Description

W E B O - solid core - assembly design with H E R A K L I T H full thermal protection Short description of the invention: "WEBO-HERAKLIT-Bauart" Field of application: Construction Purpose of the invention: quality improvement, shortened construction time, cost reduction.

Type of invention: S t ü t z 1 e i t e r for the formation of a concrete wall, whose special type and arrangement brings both economic advantages, as also brings out the functionality of the building materials used more effectively.

Known: Since the invention is based on a concrete cladding rationalization The following are the disadvantages of the known ones which are eliminated by the invention Shell concrete construction methods shown in detail.

The known types of concrete cladding differ in the main by the type of shell concrete shuttering element, a) insulation shuttering blocks b) Insulation panels clamped at a distance.

Both main types have the following disadvantages: 1. Freehand layering The cladding concrete elements (insulation material filler) are laid out in layers as well as bricks Freehand layered and aligned. So they are just as wage-intensive, like (iie conventional masonry constructions.

Sheet - 1 - of the patent specification "WEBO-HERAKLIT-Bauart" The technical one The difference between the application of mortar and the filling of concrete is only an external phenomenon.

In economic terms, both the conventional masonry-stone construction methods, as well as the well-known shell concrete constructions in that each wall length with high labor costs must be stratified and straightened.

2. The composite effect According to the latest findings, there is a composite of coated concrete with plaster layers applied directly to the insulation layers on both sides a major disadvantage in terms of airborne sound insulation. Despite the heavy wall weight (Sound reflection) and the porous insulation materials upstream of the heavy core (sound absorption) a disadvantageous combination effect occurs. The heavy wall puts together with the plaster cladding on both sides represents a double wall, its resonance frequency is in the audible range. For example, cladding concrete walls have a heavy concrete core Of 12 cm and 2.5 cm thick wood wool lightweight boards on both sides, only one measure of airborne sound insulation of minus -13 dB. According to DIN 4109 iatt 2 table 1, the minimum value for sound insulation is for partition walls at + -o dB. Walls next to passageways, etc.

must have a sound insulation level of at least 3 dB.

3. Crossbar formation Differentiate between the different types of concrete cladding basically just differ from each other by the way in which the inner and outer Damm-coat apart to an exact wall dimension and against the inflation bulge pressure is held together.

The transverse webs that hold the shell plates together have an effect one way or another always detrimental.

The statically ineffective ones interrupt with the insulating shell stones Insulation crossbars the monolithic connection of the concrete core, so that one of the special advantages of cladding concrete, the high load-bearing capacity of a monolithic Schwerbwton core layer, cannot come into its own.

Sheet - # - of the patent specification "WEBO-HERAKLITH-Bauart" for wire stapling (Spacer nails, spacer stirrups, etc.) from pond construction panels to clad concrete fillers the monolithic connection of the core concrete is not hindered. Here they go But brackets from the inside plaster layer to the outside plaster layer through and form - so far they are metallic - a punctiform cold bridge from the inside to the outside. With newer ones Methods, plastic nails (or steel nails in plastic sleeves) are used, with which the cold bridge problem is largely eliminated. The biggest weakness the wire nails or wire hanger bracing lies in the small contact surface the end of the line. The wire ends or nail heads cut into with filling pressure the resilient shell plates, so that bulges between the brackets in the Combined with the incision of the nail head or the end of the staple wire, the dimensional accuracy the wall is always endangered. Statically unjustifiable eccentricities are no exceptions and the teaching costs for the plaster compensation on bumpy wall surfaces are usually considerable. Here and there one tries to get over the evil by one produces more solid confessional building boards with a higher proportion of binding agent, which do not cut easily at the ends of the wire. Due to the higher proportion of However, binders naturally result in higher panel weights, which means a reduction the insulation ability of the jacket panels. So it just becomes an evil exchanged with another bel.

4. The position of the cladding panels According to the building physics rule of thumb should be the thermal resistance of an outer wall of a house from the inside to the outside increase, but the diffusion resistance decreases in the same direction. at the known types of concrete cladding, the thermal insulation (cladding panels) is made of constructive Reasons, however, are usually arranged half in the inside and half outside.

However, this has the consequence that the penetrated into the solid core Can only store heating heat to a reduced extent, as it is due to the reduced external insulation escapes to the outside accordingly quickly.

5. The waterproofing As with conventional stone construction are usually bilateral, even with the known types of concrete cladding sheet - # - of the patent specification "WEBO-HERAKLITH-Bauart" lime cement wet plaster on the insulation jackets arranged. In terms of the room, this is (apart from the deterioration in soundproofing that has already been discussed and the introduction of mortar moisture) with regard to moisture protection justifiable. However, the application of plaster mortar on the outside is unacceptable. The dense exterior plaster doesn't just keep out rain, snow and wind, it also prevents it also the escape of room humidity that has penetrated the wall. This vapor barrier lies directly on the important, outer Nantelplatte, which is below all Must remain dry under certain circumstances if it is to serve its purpose. about right here occurs with an unfavorable constellation of low and high outside temperatures Indoor air humidity a build-up of moisture and an accumulation of moisture as a result Condensation of diffusing room air humidity, which the thermal insulation capacity the outer shell plate eliminated. The so weakened in their functionality, The outer insulation layer can then also be used at normal temperatures and room humidity no longer fulfilling their task, which leads to the well-known moisture damage in the Wall leads, which are at the top of all structural damage.

It goes without saying that this is a fatal situation in terms of building physics even in the case of the notorious concrete cladding construction methods, by ventilating one from behind Arranges facade shell. However, this requires subsequent anchoring of the facade substructure in the hardened concrete core behind the outer insulation jacket.

Such a subsequent anchoring is, of course, always very good time consuming, costly and technically unsatisfactory.

Task: The inventive task was posed, which is below 1st to 5th

outlined, economic, technical and building physics Disadvantages of the known types of shell concrete by changing the working method without adding new, other disadvantages as a result of the change can.

Task solution: The progress was triggered by the idea of creating a Nantelbeton- Sheet - # - of the patent specification "WEBO-HERAKLITH-Bauart to develop a type of construction, which in terms of its nature and work technology is no longer the conventional one Masonry construction methods, but is more closely related to ready-made assembly methods.

The solution was found with a new type of support, which is used as a multi-purpose element, the transition from concrete cladding to prefabricated assembly and thus economic, technical and structural advantages he brings.

The advantages of the WEBO-HERAKLITH design: Essentially, the The advantages of the new WEBO-HERAKLITH design are that the (under known 1. until 5.

shown) disadvantages of the known types of concrete cladding can be avoided. The inventively brought about progress becomes with the following, alternative comparison of the WEBO-HERAKLITH design to the detailed points 1.-sc of the known types of concrete cladding justified: to point 1. (free-hand inspection The working methods of the conventional masonry-stone construction methods and related ones Shell concrete construction methods in which every single stone and every single wall layer must be stratified and straightened by hand are replaced by each new wave of wages hit fully. The shift in construction costs from material to wages occurs with every wave of prices more clearly in appearance During production, transport and delivery of the building material there was still some possibility of rationalization with which the price increase for building materials could be slowed down. At the last manipulation The material - the freehand layering - could never be rationalized Development can therefore only have an economic effect if it the manipulation of the building materials on the construction site, i.e. the working methods are decisive changed This is the Pall with the WEBO-HERAKLITH design. Hit the new WEBO support ladder the work process "layering and leveling" is significantly shortened, i.e. more rational - and therefore also more economical.

Sheet - 6 - of the 2atentschrii "t WEBO-HERAKLITH-Bauart" to point 2. (Composite effect) With the WEBO-HERAKLITH type of construction, the fatal, soundproofing deteriorating cladding concrete composite effect as a result turned off that the spars of the WEBO support ladders on both sides of the wall between The jacket and covering come to rest, which results in favorable resonance frequencies, so that even with an unfavorable layer of concrete, the sound insulation level is still within the prescribed level Plus area is.

By means of wall coverings that are unevenly thick and unevenly heavy and and / or additional backing of flexible insulation materials, or a combination of soft and hard insulation materials, the airborne sound insulation can be changed if necessary to enhance.

to point 3 (cross web training) With regard to the training of the The WEBO-HERAKLITH type provides the opposite side with the lateral webs that absorb the filling pressure the following advantages over the known concrete-clad construction: a) the punched-out web plates the WEBO support ladders hinder the monolithic connection of the core concrete j inner steepness of the wall and neither lead to the formation of cavities or that are static Strength-reducing disadvantages.

b) The web plates of the WEBO support ladders both end in the wood of the Holme, so that they cannot act as cold bridges.

c) The jacket plate contact surface on the bars of the WEBO support ladders is many times larger than the pressure-absorbing wire ends and magel heads the well-known cladding plate clamps.

In addition, the WEBO-HERAKLITH design has the weakest point the shell plate - the cut joint - on the pressure-absorbing spar of the support ladder at.

d) Even in the case of a jacket plate deflection between the spars As a result of filling errors, this cannot result in any negative effects, since the dinging takes place in the air space formed by the spar between the jacket and the surface, where it can't hurt.

Sheet - t - of the patent specification "WEBO-HERAKLITH-Bauart" to point 4. (The position of the shell plates) Because the WEB0-HERAKLITH design has loose shell plates can be deposited, can also have different thicknesses and different effectiveness Shell plates are used. Usually used when creating House outer walls in WEB0-H £ RAKLITH design on the inside thinner jacket plates (which can just about withstand the expected filling pressure) and lay on the outside thicker or more insulating cladding panels.

(1/3 of the insulation value inside, 2/3 of the insulation value is outside) the WEBQ-HERAK'lITH design mainly provides thermal insulation that is shifted to the outside the following advantages: a) The thinner, inner shell plate only acts as a thermal brake off, i.e. the heating heat first warms the room, before slowly through the braking Inner jacket is attracted by the core concrete.

b) The heating heat that has penetrated into the concrete core is absorbed by the mainly external thermal insulation effectively obstructed the further passage. Thereby the penetrated heating heat becomes in the mass weight of the heavy concrete core jammed and stored.

Full thermal protection on the outside and heat storage capacity in the Wall are known to be the safest conditions for a living climate favorable Temperature equalization in the room and keeping the outer walls dry, which in turn the full functionality of the insulation layers is guaranteed.

c) The thermal insulation of a WEB0-HERAKLITH outer wall can be adjusted depending on reinforce the climatic situation of the construction site to measure.

So it is without any technical difficulty and with little additional cost possible to insulate climatically exposed weather sides particularly strongly. The same applies to expensive heating systems, such as electric night-time storage heaters, etc. where the full thermal insulation and the heat storage of the wall are particularly favorable affects.

to point So (The sealing) With the WEB0-JiERAKLITH-Bauart in each case a ventilated outer shell (5i zetter shell) is arranged. These arrangement Sheet - # - of the patent specification "WEBO-HERAKLITH-Bauart already results from the use of the WEBO support ladder, which is a multi-purpose element first serves as a cladding concrete assembly support and after integration it is already an aligned one anchored substructure for attaching wall coverings on both sides of all Kind of educates.

The spars of the WEBO support ladders anchored in the core concrete form as Spacer an air layer between the jacket and the covering, which is on the inside for inserting installation lines and on the outside for rear ventilation the weather shell can be used.

With the - with the WEBO support ladder - constructively enforced rear ventilation The outer shell has the following advantages: a) When choosing the clothing material for the outside you don't need to take breathability into account and can be completely dense materials, such as asbestos-cement panels, aluminum sheets, plastic-coated Sheet steel, plastic plates, etc.

use.

b) Excess indoor air humidity, which through the outer wall diffuses, is no longer blocked by any wall covering and can pass through unhindered the rear ventilation escape, the outwardly decreasing diffusion resistance, the haupteächlioh to the outside relocated full heat protection and the heat storage capacity of hiking provide a guarantee for a good funlttloning protection against moisture not only in front of the wall, but also in the wall.

Economic advantages result from the air layer-forming The bars of the WEBO support ladder also on the inside, where all the small installation lines (Electric-Gas-Water-Haizungs-Telefon, etc.) in the air layer between the inner jacket and dry plaster covering can be laid. This makes the usual ones unnecessary Chiselling and slotting work to bury the lines, which usually also include a Bringing a reduction in the static wall strength and thermal insulation. As a result of that with the WEBO-HERA-KLITH design, the inner jacket plate is undamaged between the Concrete core and the pipe pipe is both a structure-borne sound transmission to the concrete core, as well as a temperature transfer of the water-carrying pipes avoided.

The possibility of efficient attachment of dry and clothing and other prefabricated technical measures, also enables significant reductions in construction time.

Sheet - # - of the patent specification "WEBO-HERAKLITH-Bauart" WEBO - support ladder (according to Figure 1 + 1.1 of the patent sketches) Height variable, usually 2.75m (wall + ceiling) Width II "O, 25m stiles" "24 / 48mm (wooden slats) web plates" "as sketch 1.1 M 1: 1 nailing flush or pull-out protruding (as in the sketches) Principle of the WEBO-HERAKLITH design The WEBO support ladder in the desired wall thickness and height is placed across the wall to be formed. (Fig. 1) The HERAKLITH nantel slats in the the desired thickness and texture are stored upright, so that the ladder stiles cover the jacket joints.

So that the shell plates remain in place before filling the punched sheet metal fingers of the web plates (Fig. 1,1) bent so that they the shell plates hold on the spar, (Fig.2) The solid core filling of this so formed, lost Formwork is done all around in layers of 50 cm. Heavy concrete is poured in according to static calculation. The filling pressure is absorbed by the jacket and conductor. (Fig. 3) After the core concrete has hardened, the cladding is attached to the integrated support ladder stiles assembled. (Fig. 4) Functional description (according to Figure 5 of the patent sketches) The function of the finished WEBO-HERAKLITH wall according to Figure 5 a - g from the inside to the outside: a) dry plasterboard Mounted (nailed) on the inner rails of the WSB0 support ladders. This prefabricated Measure enables quick and dry use.

Sheet - ## - of the patent specification "WEB0-HERAKLITH-Bauart n If requested The inner slatted spars of the WEBO support ladders are wet plastered by withdrawing the peeled off protruding nails. The protruding sheet metal web ends are left and right folded over and form an additional holder for the HERAKLITH jacket plates. A conventional interior wet plaster is applied directly to the flared plaster base.

b) The inner layer of air which through the inner slat spar between Dry plaster and cladding plate is formed, is used to bring in all small lines. The stiles can be placed between the web anchors for horizontal cable laying can be sawn through at will.

c) the inner shell plate serves as a thermal brake, formwork and intermediate cushion between the pipes and the concrete core.

d) the solid core, which is usually placed in heavy concrete B 160 B 2 is is monolithically connected at all points. The web plates lying in the concrete are permeable to the concrete and due to the bending of the stamped sheet metal fingers securely anchored.

e) the outer shell plate has the main load of the thermal insulation wear. For this reason it is thicker on the outside than on the inside.

This insulation layer has the task of the internal thermal brake heating heat penetrated into the concrete core on the further passage; to the outside to prevent effectively, so that the penetrated heat accumulates and stores in the concrete core got to.

f) The outer layer of air is used for rear lifting. The diffusing Indoor humidity is initially slowed down by the dense concrete core, but can then the easier it is to escape through the permeable, outer jacket layer for ventilation.

g) Weather shell The outer wall cladding can be made of completely dense Material exist because they are no longer breathable because of the rear ventilation needs. 5. A conventional external plaster layer can also be applied. (Bitumen cardboard, expanded metal, external plaster). When applying = sbestzementschingeln a counter batten is placed on the upright stiles. Also vertical or Horizontal wooden cladding can be attached in this way.
