Abstract

In one of the methods, connecting elements made by using concrete are produced by first pouring a fluid mortar, on the inside of a wall (1), into openings (5) of a template (2), with the addition of an adhesion promoter. A bell- or disc-shaped casting mould, which is filled with earth-moist concrete and is centred by the openings, is then placed upon this fluid mortar. The form elements thus produced can be stacked for hardening, with the interposition of thin plates, and subsequently joined to form form-element halves, for example by adhesive bonding. Modified methods produce the form elements by using dumbbell-shaped connecting elements made with the aid of axially separated mould halves. Form elements produced according to the method permit numerous modifications. <IMAGE>

Description

The present invention relates to a method for producing a formwork assembly for a concrete structure suitable for walls, in particular for exterior walls, and to a formwork assembly produced thereby.

Wall concrete structures use large form elements of rigid foam material. These formwork elements are provided with grooves and tongues at their edges, thereby securing the formwork elements in relative predetermined positions. A connection member is provided on the inner surface of the formwork element, which is located on a side wall surface of the formwork assembly, to support a force generated when concrete is poured into the formwork assembly. This type of assembly, for example,
It is disclosed in DE-AS 26 18 125 and DE-OS 3405736. The connecting members used in such an assembly include a substantially dumbbell shaped connecting member made of concrete, the connecting member comprising two mutually opposed flanges and an intermediate portion connecting the flanges. Have. The flange has free end grooves and tongues which mate with corresponding grooves and tongues on the inward side of the side wall portion of the respective formwork assembly. When the formwork assembly is filled with concrete, the connecting members are homogeneously integrated with the concrete to form an integral structure. Unlike a mold assembly that uses a metallic coupling member, such a structure in which the coupling member is made of concrete does not cause a thermal bridge phenomenon between the side wall portions of the mold assembly. Furthermore, compared to a mold assembly using a connecting member made of a rigid foam material formed integrally with the side wall of the assembly,
In the structure using the connecting member made of concrete, the occurrence of the acoustic bridging phenomenon is substantially suppressed, and the possibility that the flame propagates through the form assembly in the connecting member region can be substantially sealed. Furthermore, since it is made of concrete or a similar material, the connecting member is relatively heavy, so that when the lightweight concrete is introduced into the formwork arrangement, the formwork assembly does not rise, so to speak, on its surface. The weight of the connecting members generates considerable pressure, such as between the mutually contacting edges of the stacked form assemblies in the formwork structure, and this pressure sufficiently collapses the gap between the form assemblies and from a setting process perspective. No significant cement grout is spilled. Furthermore, the weight of the connecting members makes the rigidity and stability of the formwork during a storm, for example, at a considerably high level.

The dumbbell-shaped connecting member made of concrete is integrally cast separately from the side walls of the rigid foam constituting the side portions of the formwork assembly, and the inner grooves formed on the inward side surfaces of the side walls of each formwork assembly. It is fitted, engaged or fixed by the bonding means put inside. This operation can be performed continuously at the factory or at the construction site. The dumbbell-shaped connecting member may be cast in two parts and interconnected by an intermediate part in the form of an eye, hook, wire, bar, screw or the like. This is described, for example, in DE-OS 36 01 878.

Formwork assemblies of the above type have proven to be quite successful, but their manufacturing costs are relatively high,
In addition, it takes a long time for the concrete portion of the connecting member to harden, and a considerable space is required.

According to the present invention, there is provided a formwork assembly for a concrete wall structure, comprising at least one connecting member made of concrete or concrete-like material interconnecting the first and second wall portions. And a method of manufacturing a substantially dumbbell-shaped formwork assembly comprising flange means which can be fixed to a wall portion in which the connecting members are arranged opposite to each other and an intermediate portion between the flange means. A) mounting a template having an opening conforming to the shape of the flange means inside one of the wall portions; b) introducing a flowable mortar into the opening; Smoothing with a glue that is suitable for the material of the part and joins the mortar to the wall part; and c) conforms to the flange means to be produced and forms the flange. Filling the dump concrete into a mold having an oriented opening to finish smoothly; d) turning the mold upside down to fit the flange forming opening with the mortar in the opening of the template; e) the mold and the template. Removing the method.

In another aspect, the invention provides a formwork assembly made by the above method, wherein at least one wall portion is made of a rigid foam material.

In the above-described method of the present invention, the connecting member is directly cast into the wall portion of the mold assembly, so that another manufacturing step is not required. By using a flowable mortar or float mortar with a suitable adhesive, a very good and durable connection can be made to the wall of the formwork assembly that can withstand tensile stresses. While it is easy to add the adhesive to the mortar, the adhesive may be applied to the wall at least in the opening area of the template, for example by spraying, painting or coating. The adhesive may also be applied to the wall of the assembly by dipping the wall in a suitable bath.

According to another preferred feature, a colorant may be added to the adhesive to provide a coloring effect on the snow white outer surface, especially when a rigid foam material is used for the wall portion of the assembly. This dazzling pure white appearance can cause various problems, especially when exposed to sunlight, and can lead to a disease similar to that known as snow blindness.

According to another preferred feature of the invention, the freshly made wall sections can be stacked on top of one another to allow the concrete to fully harden or store, significantly reducing the space required for the production and storage of formwork assemblies. be able to. To that end, the finished wall sections are layered on a substantially flat surface, with the flanges of the wall sections located on the upper side, and then a thin sheet layer, such as a plywood panel, is placed on the flanges of the connecting members. And then another layer of the wall section is placed on the intermediate board. These steps are repeated to form a stack that can be several meters high. After forming each layer,
At the beginning of the layer, the concrete of the connecting member is sufficiently hardened, so that placing the next layer in place on the thin intermediate plate no longer risks deformation of the connecting member. To this end, each adjacent layer of the wall portion is fixed for a period of time so that sufficient time has passed before setting the next layer in place on the intermediate plate placed on the previously formed layer. Must be the same length. Prior to forming the wall sections in such a stack, the free ends of the flanges of the respective wall sections are set at a predetermined height, for example by means of a template. The template may, for example, be in the form of a bridge, and may be formed, for example, by scraping or removing a small amount of material or by lightly pressing the end of the flange portion. Formwork assemblies formed from these are of very accurate and uniform form, with very precise internal and external dimensions.

In accordance with yet another aspect of the present invention, the coupling member can be of a wide variety of shapes and dimensions. The flange is preferably circular, but may be oval, rectangular, or square. The mold into which the concrete is cast may be substantially bell-shaped. In that case, the stem portions join the respective flanges. For the purpose of joining the two wall parts to obtain the formwork assembly, the free ends of the stem parts are fixed to each other by adhesive means. Using a simple form of instrument, the ends of the stem portions can be precisely matched to provide a precise formwork assembly. Prior to the hardening of the material, at least one groove-shaped depression can be formed at the transition between the respective flange and stem portion and used as a mounting site for a reinforcing rod or bar. This can be done, for example, by pushing the rod or bar into place.

However, the mold for making the flange may be configured to make a substantially disk-shaped flange. The flange has a central recess, which is preferably cylindrical. In order to interconnect the first and second wall portions to obtain a formwork assembly, the rod-shaped intermediate portions are secured with an adhesive in opposing recesses of each of the wall portions. The middle or part acts as a connecting element. By varying the length of each intermediate portion, the internal dimensions of the formwork assembly can be adjusted, and thus the thickness of the concrete wall to be subsequently cast.
The intermediate part may be made of concrete by means of a hollow cylindrical mold. Before the material is cured, a groove-shaped depression may be formed in the region at both ends of the intermediate portion, and a reinforcing rod or a reinforcing bar may be attached later.

According to another preferred feature of the invention, a rod, a bar,
Lateral securing means, such as hooks, eyes, screws, wires, metal strips, etc., may be embedded in the flange or adjacent stem portion prior to curing of the material. Similarly, the holes may be pressed into the flange by a suitable tool, such as a nail or a pin, in a basic form. These holes serve as mounting positions for later fitting of the lateral fixing means.

The uniform spacing (e.g., 25 cm) of the connecting members made by using the template provides a certain dimensional pattern in which the connecting members are present at specific intervals in the formwork formed by the formwork assembly. . At the actual construction site, the formwork assembly can be sawed between the connecting members, but the assembly cannot be sawn at the actual connecting member position. According to a further preferred feature of the invention, this limitation can be overcome as follows. That is, the flange is fitted into a mold for manufacturing, and the stem-like intermediate portion is a center plate extending in the height direction of the mold assembly along the axis of the connecting member. The finished formwork assembly can be cut off parallel to and aligned with the respective separating plate, so that what can be referred to as a half formwork assembly, i.e., exactly at the center of the connecting member It is possible to use the cut formwork assembly. In general, the formwork assembly must be cut in this manner in the area of each end, so that in this preferred feature, the separator is a flange-like or stem-like intermediate piece adjacent each end of the wall portion of the assembly. Used only for parts.

As mentioned above, in the formwork assembly made by the method according to the invention, at least one wall part is made of a rigid foam material, but in general both side wall parts and any end wall parts which may be used Consists of a rigid foam material. The wall of the formwork assembly can also be made of materials such as gypsum, lightweight gypsum, gypsum, cement, concrete, clay, and the like. This wall later forms the interior surface of the concrete wall formed by the plurality of formwork assemblies, substantially preventing sound from propagating along the concrete wall. In addition, such walls do not produce hollow sound when tapped or impacted.

Here, it should be understood that the method according to the invention allows the formwork assembly to be made from smooth plates cut from blocks. However, a stitching structure may be provided on the inner surface of the wall portion in order to increase the holding force between the flange of the connecting member and the side wall portion of each mold assembly. Preferably, the groove has an undercut for improving the fixing of the flange. The cross-sectional shape of the groove may be selected according to any given situation, for example, the special requirements associated with a bee-shaped, open semi-circular, full circular or other configuration. The wall portion may have retaining grooves at the top and at the end.

According to another preferred feature of the invention, the fixing wire may be cast in the flange. The wire is then withdrawn from both sides through a tubular intermediate section. The intermediate portion has edge openings or holes at both ends. The wire is then guided outward through the hole and twisted to provide tension. Thus,
The formwork assembly can be easily achieved on site, with the requirements associated with each. Different wall thicknesses can be obtained by using different length intermediate sections.

An end piece for closing the formwork assembly in a wall edge or corner configuration may be glued to or between the ends of the wall portion of the formwork assembly. In this case, for example, in order to improve the stability at the window or door opening, the end parts of the plurality of formwork assemblies arranged one above the other may form a continuous plate or panel structure.

For a strong connection between the flange and the wall part of the formwork assembly, the wall part may be provided with a slot extending from top to bottom, at least in the region of the flange. The width of the slot may be half the diameter of the flange. This slot can later be sawed in the field, the concrete of the respective elements can be continuously connected to each other at the wall joints or corner joints, and there are also interruptions due to the rigid foam wall sections It is not allowed. This increases the strength of the structure and eliminates the risk of acoustic bridges and flame propagation through the wall structure.

Referring first to FIGS. 1 and 2, the individual steps of a method of manufacturing a formwork assembly are shown.

Reference numeral 1 indicates a side wall portion that is a part of the formwork assembly, and the formwork assembly is composed of two such side wall portions. Formed on the side wall part 1 is a formwork 2, which is made of a suitable material such as a plastics material or a metal. The positioning pin 3 places the side wall portion 1 and the template 2 in a precise positional relationship, for example, on a surface of a work bench or the like. The side wall portion 1 is made of, for example, a rigid foam.

Unlike the side wall part 1 shown in FIG. 1, the wall part 1 shown in FIG. 2 has a plurality of dovetail-shaped grooves 4.
However, as pointed out above, the groove 4 is only an additional preferred feature of the present invention and need not be provided.

The template 2 has a plurality of openings 5 which are circular as shown and are evenly spaced from one another to define the dimensional pattern of the connecting member which it is to form. ing. The openings 5 may be different in shape, may be unevenly spaced from each other, or may be arranged at eccentric positions. After the template 2 has been placed on the wall part 1, its arrangement is in the form shown in FIG. Next, a flowable or floatable mortar containing an adhesive suitable for the material of the wall portion 1 is introduced into each opening 5, and the mortar is flattened. The result is the state shown in FIG. 2b, which is shown for the two openings 5 on the right side of FIG.

Here, it should be noted that instead of mixing with the mortar, the adhesive may be applied to the wall part in the form of a coating at least in the region of the openings 5 or may be applied, for example, by dipping. The adhesive may be colored.

Subsequently or in parallel with the step in the state shown in FIG. 2b of the method, concrete 8 is filled in a casting mold 7 having a substantially bell-shaped configuration. Concrete is dump concrete with low moisture content. The mold is filled with its large opening facing upwards, and thus in an inverted position relative to the position shown in FIG. 2b. Thus, concrete 8
Can be easily and conveniently introduced into the mold 7.

The mold 7 is turned upside down and applied to the mortar 6 in each opening 5 while the concrete 8 is still wet. The edges of the mold 7 are received in the respective openings 5, and the mold 7 is precisely positioned with respect to the openings 5 as shown in FIG. 2c. Next, the mold 7 is removed.
Perhaps with the help of light vibrations and beatings to make the concrete 8 easier to peel from the mold 7. Subsequently, the template 2 may also be removed to obtain the configuration shown in FIG. 2d.

As shown in FIG. 3, the wall portion 1 forming the connecting member portion (indicated by reference numeral 10 in FIG. 3 and consisting of concrete 8 and mortar 6) has a substantially flat surface, for example, on a concrete floor of a building. In a row. For example, the length of a row is 10 to 30 meters or more. When such multiple layers of one layer are created, a thin plate member 11 (eg, a plywood panel or panel member of another material, 10
(Having a size of 0 cm × 200 cm × 0.3 cm) at a predetermined position on the connecting member portion 10. Next, the next layer of the connecting member portion 10 is set at a predetermined position on the plate member 11. In this way, for example, a stack with a height of a few meters can also be formed.
In any case, it is necessary to allow sufficient time for the concrete 8 of the connecting part 10 to firmly solidify so as to be able to support the loads applied by the stacked layers.

Referring now to FIG. 4, here, the two wall portions 1 of the formwork assembly having the connecting member portions 10 are attached to each other by fixing the end surfaces of the connecting member portions 10 to each other with an adhesive. A method for forming a mold assembly is schematically illustrated. If a simple tool (not shown) is used, an accurate mold assembly can be obtained by accurately aligning the end faces of the connecting member portion 10. In this way, a substantially dumbbell-shaped connecting member 20 can be obtained, which is formed by the first and second portions 10, respectively, and each connecting member 20 connects the first and second flanges 12 to them. And an intermediate portion 13. The intermediate part 13 has a substantially stem shape in the embodiment shown.

In the embodiment shown in FIG. 5, a connecting member portion is manufactured using a mold (not shown) having a shape of a shallow dish or bowl different from the mold 7 shown in FIG. 2d. Has only a flange 22 having a central depression indicated by 14. When assembling the two wall parts 1 with the flanges 22, the stem-shaped intermediate part 23 is fitted into the recess 14 and secured thereto, for example with an adhesive.

In the two embodiments shown in FIG. 4 and FIG.
3, 23 each form a groove-like depression, generally indicated at 15, in the region of the transition to the respective flange 12 or 22, before the concrete hardens. This indentation will later serve, for example, for mounting a reinforcing rod or a reinforcing bar (not shown).

Next, refer to FIG. Shown here is a casting mold 17, which generally corresponds to the mold 7 shown in FIG. 2d,
There is a central separator 16 thereon. The connecting element part made of the mold 17 shown in FIG. 6 is the same as the part 10, but is divided into two parts and subsequently the mold made by the wall part 1 provided with such a connecting member. The frame assembly can be split at this location. This is shown, for example, in FIG.
Can be carried out by sawing as schematically shown in FIG. Therefore, in addition to separating the formwork assembly between the respective connecting members 20 in the area indicated by the broken line 19, the formwork assembly can be formed according to a dimensional pattern determined by a spacing of, for example, 25 cm between adjacent connecting members 20. It can be cut off at half of the dimensional pattern described above, so that the formwork assembly can be easily adapted to the respective structural requirements of a given site.

FIG. 8 shows another embodiment of a formwork assembly according to the present invention, which also includes a flange 22 and a central recess 14 similar to that shown in FIG. These flanges are cast into the wall part 1 in the manner described above. Prior to hardening of the concrete, a further wire 24 is fixed to the flange 22. For the purpose of assembling the two wall sections 1 with the flanges 22, a tubular intermediate section 33 is used, which may also be made of concrete. The wire 24 passes through the inner diameter hole of the tubular intermediate portion 33 from both sides and is pulled out,
It is then twisted and tensioned, whereby the wall parts 1 are drawn towards each other and come into firm contact with the intermediate part 33. The opening 25 at the edge of the middle part 33 allows the wire to be easily pulled out of the middle part.

In the embodiment shown in FIG. 9, a metal strip 26 is fixed to the flange 22. The two wall sections 1 with the flanges 22 are interconnected by this strip 26. For example, the holes in each strip 26 may be interconnected through screws or wires, or
The connection may be performed by spot welding. An elongated piece 28 having a hole 27 can be incorporated to extend the spacing and increase the internal width of the formwork assembly.

FIG. 10 is a schematic view of a form of a corner connection portion. FIG. 10a shows the first layer of the formwork assembly and subsequent layers which are the odd numbered layers, and FIG. 10b shows the second layer of the formwork assembly and the subsequent even numbered layers. . In FIG. 10 a, in the region of the left intermediate part 20, the inner wall part 1 is provided with a cut-out or opening 29, which faces the bottom of the flange 12. When the formwork is filled with concrete,
A connection of the concrete structure is made at the flange 12 and a continuous concrete wall structure extending as a unitary structure through the corners is obtained, and is interrupted by the presence of the rigid foam wall part 1 in the concrete body. No part. Therefore, this structure becomes a fire-resistant wall. A similar configuration is applied to the next upper layer as shown in FIG. 10b, where there is an opening 29 through which the concrete extends continuously through the corner configuration.

Figures 11a and 11b each show a wall joint with alternating layers. This structure also has an opening 29 for providing a continuous concrete section to the wall structure. This type of continuous concrete core configuration not only prevents acoustic bridging, but also reduces the risk of flame propagation through walls and can withstand higher static loads.

Here, it should be noted that FIG. 10 also shows end 30, which is fixed between the wall portions with an adhesive or the like, closing the form assembly outside. A similar part is indicated at 30 in FIG. 11b, which also closes the structure between the ends of the wall part 1.

As is evident from the foregoing description, the above-described method of manufacturing a formwork assembly for a concrete wall structure is an improved method that can reduce manufacturing costs and withstand greater loads that will be subjected in the future. Provide an inexpensive formwork assembly. Also, the task of casting a flange of concrete or similar material is greatly simplified because concrete can be introduced downward into a relatively large opening that defines the surface connecting the connecting member to the corresponding wall member. The mold is reusable, and the template ensures good dimensional accuracy and repeatability of the formwork assembly.

A particular advantage of the formwork assemblies produced by the above method and its variants is that it uses smooth walls, for example cut out of blocks, preferably hard foam material, without using grooves or other depressions or related features. It is possible to do that. There is no need to use expensive injection molds, so the formwork assembly is cheaper and can be manufactured, for example, like hollow building blocks. Due to the relatively high weight of the concrete connecting member itself, optimum stability is ensured even for walls at the height of the ceiling, which can then be filled with ordinary concrete or lightweight concrete. Similarly, the weight of the concrete connection member prevents the mold assembly from lifting when filled with lightweight concrete. If this arrangement provides an additional safety measure against wind or storms, for example, the stacked form assemblies may be glued together prior to filling with concrete.

In a variant of the method of manufacturing a formwork assembly for a concrete wall structure, the assembly comprises a first and a second wall part and at least one connection of concrete or concrete-like material interconnecting the wall parts. Consisting of components,
The corner connecting member is substantially dumbbell-shaped and has flange means for fixing to mutually facing wall portions, with an intermediate portion between the flange means and divided axially. A mold part having an internal contour corresponding to one half of the dumbbell-shaped connecting member is filled with concrete or concrete-like material and flattened along the separating plane for the axially divided connecting member. next,
First and second mold parts necessary to construct a secure mold are aligned with each other along the plane. After the material is at least partially cured, the mold portion is removed and the connecting member is glued to the first and second opposed wall portions using an adhesive with approximately the same volume as in the previous embodiment. In this alternative embodiment, the substantially dumbbell-shaped connecting member is made by a mold part that corresponds to half of the axially separated connecting member. The mold parts may be mated immediately after filling with cocrete or concrete-like material. Then, the concrete portions filling the two combined mold portions can be combined to form respective connecting members. However, as another feature of the present invention, a separating agent or separating material (eg, foil) between the two mold parts
It is also possible to make the respective parts of the dumbbell-shaped connecting member. These connecting member portions may be used individually while pressed against each other to create a formwork assembly, or may be secured together by an adhesive. The operation of filling the mold part with concrete or concrete-like material can be manual or mechanical and can be performed by pouring concrete into the mold part, stirring, pressing and shaking. Depending on the method used, the concrete or concrete-like material may be between a dumped state (ie, low moisture content) and a liquid state.

In a further variant of the method according to the invention, a first and a second mold part, each having an internal contour corresponding to one half of a substantially dumbbell-shaped connecting member divided axially, are separated by a separating plane of the connecting member part. Are aligned with each other and then joined together to form one mold. The mold is placed on a flat surface and its axis is vertical before filling with concrete or concrete-like material.
After the concrete has at least partially hardened, the mold part is removed. Next, the connecting member is bonded to the first and second mutually facing wall portions using an adhesive. Thus, in this method configuration, two axially-divided mold parts of the type described above are used in alignment with one another and then secured together by clamping or clipping means. Thereafter, the concrete or concrete-like material is filled to form a mold for receiving the concrete or concrete-like material. The connection at the edge of the cooperating mold part can be further improved by means of a stitch configuration. The operation of filling the mold thus made can also be performed by injecting the material into the mold, mixing it in the mold and applying pressure from above and below.

In the above two variants, the reinforcing wire may be introduced into the mold or in each mold part at a position substantially in the axial direction. This makes it possible, in particular, to contour the wire and to weld it to the end of the wire, or to form it by swollen swaths, or to bend the ends at the ends so as to form a thickened part and engage the hook action. , The tensile strength can be considerably increased. For example, if the connecting member breaks during transportation, the wall portions of the formwork assembly can still be connected by wires, and a high level of tensile strength can be obtained.

In the present invention, the mold portion can be made of any suitable material, for example, a metal (eg, a steel plate) or a plastic material.

While various forms of the method and formwork assembly have been described, these are merely illustrative of the invention, and various changes and modifications may be made without departing from the invention as defined in the appended claims. It should be understood.
