USE OF BETONYP BOARD

5.1 SHUTTERING

The BETONYP building boards are adaptable to prepare several kinds of form-works or to make a complete shuttering system creating a full scale of sizes and types of boards.

Re-applicable as well as built-in form-works can be created.

In both cases any configuration, building wing or plane intended to be created by shuttering will be prepared for further uncomplicated surface formation methods.

Shuttering types can be formed with BETONYP building boards:

Dry form-works for socle and lost-in shuttering called shuttering block as well

Prefabricated lost-in shuttering mounted with reinforced concrete sometimes with heat insulation for walls of cellar or other buildings

Roof form-works

For the architecture to the built-up BETONYP building boards with appropriate thickness and size should be selected in order that to meet the static requirements and regulations for the construction.

When using re-applicable dry form-works, a special anti-binding additive must be applied so as to avoid the formation of a permanent joint between the form-works and the construction body. In case of lost-in form-works to create perfectly gap-free surfaces, formation of a secondary casing is recommended with gypsum or gypsum-fibre boards.

5.2 EXTERNAL CLADDINGS

Using finished or unfinished BETONYP building boards a frame-based cladding technics with built-up elements can be created which is suitable to the simultaneous cladding and insulation of facades.

Applicable to create

External cladding of facades such as:

Aesthetical cladding,

Cladding combined with supplementary insulation,

Additional protection against rainfalls.

Supplementary elements for external claddings such as:

Requires dry technics for implementation,

Implementation is independent of seasons or weather.

Regarding the aspects of maintenance:

The general maintenance required in a cycle of 10 years for traditional plasters can be eliminated.

Only worn colour must be refreshed.

The external cladding has the same durability than the base construction has.

Using BETONYP building boards the following cladding systems can be created:

Cladding systems with big elements,

Cladding systems with intermediate elements,

Cladding systems with small elements.

The ways of fixing can be:

Visible or invisible.

Setting of covering elements can be:

Accentual or unaccentual and overlapped in a scaly way.

When using the BETONYP building boards for cladding, instructions for the base material should be taken into consideration.

5.3 INTERNAL CLADDINGS

The cement grey coloured BETONYP building boards can be used for creating several kind of internal claddings which are designed, machined to dimensions, and finished according to the requirements of the final utilization.

Applicable as room divider in:

Public institutions

social institutions as an aesthetical and fire protective cladding, thermal insulation, airborne sound insulation, and protection against vapour diffusion.

Applicable as supplementary element for interior decoration like:

side-rails for staircase, aesthetical accessories

aesthetical covering for pipe fittings and cables

sounding-boards

5.4 FLOOR COVERINGS, STILTED FLOORS FOR COMPUTER ROOMS

Mechanical properties of BETONYP building boards offers a wide range of utilization, such as replacement of concrete base layers or information of stilted floors for computer rooms.

A new product the BETONYP PLUS fibre-forced building board can offer many new possibilities for application. One side of this board is reinforced with a fibreglass-polyester net of high tensile strenght. When bending stress occurs this fibre net situated in the section of tensile load.

Therefore tensile strenght of the building board is significantly increased.

To cover floors or replace concrete base layers boards of standard sizes can be applied or prefabricated and custom-made boards can be prepared with a supplementary insulating layer of several types of materials and thickness.

Finished floor elements can be applied for:

panel,

moulded or light-weight building methods.

Applicable in:

family dwelling-houses, living rooms

public institutions, rooms with warm floor

office buildings, office rooms

Advantages of application for floor coverings are as follow:

the weight of construction can be minimized,

fast implementation, excellent sound and heat insulation properties,

provides an ideal under-plate for parquet floors, PVC floors, and broadloom carpets,

offers a building method not requiring additional water content to avoid the unintended damage of existing constructions.

Floor coverings made of BETONYP building boards should be designed to meet the requirements of the final utilization of the construction and mechanical properties of building boards should be taken into account.

Physical and mechanical properties of BETONYP building boards allow their utilization as a covering material for assembly tunnels hidden above suspended ceilings or under stilted floors of computer rooms.

In case of utilization for the above-mentioned applications the following aspects should be taken into account:

Thickness tolerance of the BETONYP building boards can reach +- 1,0 mm. Therefore application of products prepared with justified sanding is offered.

Thickness and dimension scale of the required elements determined by the supporting frame system.

Further mechanical properties recommended to be taken into account are:

- general strenght properties,

- creep of building boards due to bending stress,

- equilibrium conditions for loading of boards.

The BETONYP boards meet the former requirements and possess the needed dimension scale can be finished and cladded according to the customer’s requirements with material appropriate to create anti-static walking surface.

5.5 ELEMENTS FOR SUSPENDED CEILINGS

After proper design of the construction the BETONYP building boards can be offered as a cladding material for suspended ceiling systems.

Using suspending elements the following applications can be made:

unaccentual suspended ceiling with hidden fixing points

accentual or jointed suspended ceiling with visible fixing frame

The field of application can be wide because of the properties of system elements and of the construction. Applicable for intermediary and roof ceilings of any building to create plane and horizontal suspended ceilings with the following functions:

fire protection,

decoration,

heat insulation,

airborne sound insulation.

Occasionally the functions of application are multiple:

fire pretection with the insulation of airborne sound,

insulation of airborne sound and decoration.

The building construction should be designed according to the mixed requirements and mechanical properties of either the other components and of the BETONYP building boards as a main component should be taken into consideration.

5.6 SELF-SUSTAINING WALL AND PANEL CONSTRUCTIONS

In the building industry the application of light-weight constructions spreads widely, and gets gradually accepted, even more in certain areas their application is essentially required besides the traditional solutions. The possibility of a fast implementation and the relatively low expanses are the main reasons for this tendency.

A small segment of the application and utilization possibilities of the BETONYP building boards has been introduced by the previously mentioned solutions. In light-weight architecture this product has a significant role during the creation of the different kinds and types of wall constructions and building board systems.

Regarding the function of the wall construction the following applications are offered:

external and internal load-bearing walls, wall-panels,

deviders, wall-panels,

frame filling wall-panels,

roof and ceiling constructions, panel constructions,

other supplementary constructions and panels.

Regarding the construction the following types can be created:

small panel constructions,

intermediate and large panel constructions,

constructions mounted on a frame,

frame-constructions mounted on the spot.

The BETONYP building boards can be mounted on the following frame types:

wooden-frame constructions,

metal-frame constructions,

the frame construction itself made of BETONYP building boards, too.

The above-mentioned constructional solutions can be applied to construct several kinds of buildings on a wide range from communal institutions and industrial facilities through sheds and hangars to dwelling houses.

Prior to the building process these constructions should be designed according to and in compliance with the requirements proceeded from the final utilization of the building. During the design procedure all instructions referring to the application of BETONYP building boards should be strictly observed.

It is important to study what kind of other materials will be applied during the construction and whether the contractor staff will have the required skill and expertise to work with these materials.

Mechanical properties and main features of both the BETONYP building boards and the other base materials should be taken into consideration in order that constructions can be developed in a functionally and technologically correct way. Therefore the expedient design procedure of the construction has a special importance.

Building constructions may have so called secondary functions as well which depends on the environment they are intended to be built in or on architectural and regional regulations must be complied.

Regarding the secondary functions the construction can be an additional:

heat insulation,

fire protection,

sound insulation.

In accordance with experience of several years it can be stated that architects familiar with mechanical properties of BETONYP building boards have designed and built several constructions meeting all those requirements – even special ones too – which are to be taken into consideration.

Some special physical properties which can be provided with the application of BETONYP building boards:

Accounting on thermal properties energy saving constructions can be designed according to requirements of our days.

Constructions with excellent coefficients of thermal conductivity and heat transmission can be designed.

Good critical values of fire resistance can be reached with expedient board constructions.
Regarding the high density value of BETONYP building boards they can be used for acoustical applications too, but principally in constructional forms.

Design of special constructions has to be inspected by assigned authorities in any case.

6. Additional information on constructions made of BETONYP building boards

When building a construction applying BETONYP building boards, some of the final skilled works has to be accomplished in a different way than it is usually made and a special care is required.

In the following chapters some of these skilled works requiring special expertise and care will be introduced.

6.1 BRICKLAYING OF CHIMNEYS

In the roof a hole for the chimney-shaft must be prepared during the construction of the building. The roof structure must be evolved not to contain any break through the load-bearing beams, and this rule has to be taken into consideration during the design and the implementation process.

At the brickwork of a chimney it is an important instruction that the chimney-shaft must be placed at least 10 cm far from the wall-boards. The chimney-hole in the roof and the wall-board around the chimney-shaft must be covered by asbestos boards.

When placing a stove or a fireplace by the well-boards, a similar procedure of construction must be followed.

Any heating device is recommended to be built in the same room the chimney-shaft, on the contrary the smoke outlet has to be led to it through the light-weight structure of the wall.

6.2 ELECTRICAL INSTALLATIONS

In a building structure the horizontal and vertical electrical cables must be led in standard plastic wall-tubes of a diameter of 23 or 16 mm.

Preparation of holes for sockets and fittings:

Socket holes can be prepared using a special borer with a diameter of 68 mm designed expediently for sinking socket holes. The applicable sockets – type UGD 60 is recommended – should be placed into these holes.

The plastic sockets with 60 mm of diameter and also 60 of depth can be mounted from only on side of the wall in order that aesthetical fittings can be applied. The fastener tongues of UGD 60 flush-mounted socket provide firm fixing to boards with 8-30 mm of thickness.

Any building structure can be selected by the customer, but it is very important that electrical installations must be accomplished with a special care and expertise.

During the setting of spot, halogen or other type of lights can be flushed into the roof or ceiling, the instructions of the manufacterer should be applied with special attention to technical conditions that can occur at these constructions.

6.3 BUILDING CONSTRUCTIONAL WOKS

6.301 Hot and cold water supply

In constructions made of BETONYP building boards a plastic conduit-pipe system can be applicable for providing both hot and cold water supply.

Its main advantage over steel pipes is that the flexibility of plastic pipes ensures that they can be flush-mounted into the light-weight wall construction without crossing any vertical frame-rib.

Since fittings can be found at the ends of the pipes the plastic water pipe can be led in an intubation tube with a diameter of 23 mm in any place.

Installation holes for flush-mounted pipes and fittings can be prepared using carbide tipped disk saws with cutting depth adjusted to 12 mm or other cutting tools can be used such as compass-saw or socket-place borer used at electrical installations.

Leading pipes through the roof or a wall-board, a metal or PVC sleeve must be placed into the hole as a liner.

Set up on the wall:

Equipment with weight above 5 kg (basin, WC, flush-box) can be firmed on the wall by using a steel plate with a thickness of 2,5 mm which must be mounted direct to the wall-board.

The plate size and the fixing position on the wall should be defined in order that the plate can be connected to two frame-beam at least.

6.02 INSTALLATION OF HEATING SYSTEMS

For heating of buildings made of light-weight construction principally the application of central heating is recommended (with radiators or by floor-heating).

Preparation of wall break-throughs and installation of fittings are similar to of water supply described in the previous chapter.

Using radiators for heating purposes the application of flexible mild steel pipes is recommended. The mild steel pipes envoloped with double plastic liner are perfectly corrosion-resistant. Therefore on the ground-floor the pipes can be sunk in the base concrete without any heat insulation and on the upper floors the pipes can be flush mounted into the floor-aligning BETONYP boards having a thickness of 20 mm under the floor covering.

On the ground-floor and technics of construction and installation of the floor-heating system equals to the generally applied flush-mounting technics using cement-aestrich.

In case of built-in upper stories, because of restrictions derived from the construction, only dry building technics can be applied for flush-mounted floor-heating. One solution is offered by the application of heating lamellars and an other by the application of radiating aluminium foil.

After laying the heating pipes the construction must be covered with a BETONYP board with 20 mm of thickness so as to avoid the harmful overloading of the plastic pipes by the walking surface and active load.

As a covering for the walking surface broadloom carpet, plastic covering, and tile covering embedded in flexible adhesive can be recommended.
