Description

The invention relates to a reinforcement bracket for a concrete core temperature control module for Concrete ceilings or floors, with a trestle and at least one on two Vertical struts of the trestle frame arranged cross member, according to the preamble of Claim 1.

In building construction, floors or ceilings are increasingly made from prefabricated parts forms, which are either already delivered as prefabricated parts from the concrete plant, or to be completed on site. This is becoming increasingly common, especially in larger buildings Floors or ceilings installed, in which in the neutral fiber, i.e. in the central height horizontal plane in which no forces act even when the ceiling is slightly bent, Pipes are usually laid in a meandering pattern, through which a heating or cooling medium circulates. These pipes are completely cast in the concrete element sen. For tempering the building - be it that it is heated or cooled should - a medium, usually water, is pumped through the pipes where through which the concrete part heats or cools depending on In this way, an is multiple temperature control of the building possible, using this so-called concrete core temperature control mainly used to cool a building, as this makes it large Cooling powers in the range of 50-70 W / m2 can be achieved.

Such a concrete element is usually built on site on the construction site. Nor The lower formwork level is usually created on site by the shell construction company. On this lower formwork level is initially used to ensure spacers ner sufficient embedding of the lower reinforcement applied, to which the lower reinforcement layer is placed. Now put on the lower reinforcement layer so-called concrete core temperature control modules. These are Pre-assembled pipes on large-area carrier mats, so-called Q-mats which ultimately circulates the medium. Below are spacers in the bottom Reinforcement position set, after which the upper reinforcement layer is placed on this becomes.  

In order to raise the concrete core temperature control modules in the middle, it is from DE 39 06 729 C1 known to hook this in the form of suitable suspension means elements on the upper reinforcement layer, including the concrete core perforation modules must be raised.

Then the potting takes place. An alternative method, as described in DE 198 32 289 A1 is known, on the other hand, suggests the use of a rebar with cross girders that are so high on the vertical struts of the trestle that a pipe register or concrete core temperature control module attached to them in the Middle of the concrete element. Cables are used to attach them to the cross beams binder used.

The published patent application DE 100 01 039 A1 describes a structural steel construction Concrete slab element with integrated heating and cooling function, which is a reinforcement grid includes and in which the heating / cooling pipes are spaced from the reinforcement grid. For this elongated beams are used, on which the heating / cooling pipes by means of fixings are secured against floating floatation elements. For use comes a reinforcement bracket for concrete ceilings / floors to hold a concrete core temperature control module with a fixed frame and at least one on two verti Kalstreben the trestle arranged cross members on the holding means for on bring or pinching the concrete core temperature control module are provided.

It is disadvantageous in the method known from the cited prior art but that the positioning of the concrete core temperature control module is very cumbersome. In one case it is necessary to put this on the top layer of reinforcement to lift and only at the upper reinforcement layer using suitable se to hang up separate hangers, which is very cumbersome. Otherwise it has to Concrete core tempering module also raised and using around fixed cable ties to be attached to the cross members.

The invention is therefore based on the problem of specifying a reinforcement bracket, which enables easy holding of a concrete core temperature control module and for this Holding elements for hanging or clamping the concrete core temperature control module provides.  

To solve this problem with a reinforcement bracket of the type mentioned provided according to the invention that at at least one end of the cross member Holding element in the form of a barb-shaped bend in the cross member end is trained.

The reinforcement bracket according to the invention allows the concrete core to be simply connected temperature control module with the trestle, for which the holding element on the cross member is provided, in which the concrete core temperature control module is inserted in a simple manner hangs or can be pinched without any additional Holding or fastening means are required. Appropriately at both En that of the cross member such a holding element is provided to the concrete core temperature fixation module at as many points as possible.

Such a holding element is expediently arranged and designed in such a way that that the concrete core temperature control module is placed on the cross member from above can, so it rests on it.

The attachment is done in a simple manner by hooking or clamping the Concrete core temperature control module - expediently, of course, to make it more stable Carrier mat - in the hook-shaped bends.

In addition to the reinforcement trestle, the invention further relates to a concrete ceiling or a Concrete floor, comprising at least one cast-in concrete core temperature control module, that is also cast on reinforcement trestles of the type described above is supported.

Furthermore, the invention relates to a method for producing a concrete ceiling or a concrete floor of the type mentioned, comprising the following steps:

• - Connecting the reinforcement blocks of the type described above with a concrete core temperature control module,
• - Setting the reinforcement blocks together with the concrete core temperature control module in a lower one re reinforcement layer,
• - placing the upper reinforcement layer on the reinforcement trestles,
• - pouring the concrete.

In this embodiment of the invention, the reinforcement brackets are initially included connected to the concrete core temperature control module or attached to it, after which the concrete core temperature control module with the reinforcement frames arranged on it the lower reinforcement layer, which rests on the small spacers of the formwork, is set. This means that there is no further work on the formwork in the Connection with the fastening and positioning of the concrete core temperature control modules required, as these already attach the reinforcement brackets due to the fastening they are properly held and positioned.

An alternative process design for producing a concrete ceiling or a concrete floor comprises the following steps:

• - introduction of a lower reinforcement layer,
• - placing the concrete core temperature control module on the lower reinforcement layer,
• - Setting the reinforcement brackets of the type described above in the lower reinforcement position and the concrete core temperature control module,
• - Raise the concrete core temperature control module and connect the concrete core temperature ration module with the holding elements of the reinforcement blocks,
• - placing the upper reinforcement layer on the reinforcement trestles,
• - pouring the concrete.

In this embodiment of the invention, the connection of the concrete core temperature takes place module with the reinforcement frames only on the formwork, for which the concrete core temperature control module must be raised. However, the connection is very simple, since the concrete core temperature control module only in the holding elements on the jacks must be clamped or hooked in.

It is particularly useful if reinforcement blocks with holding elements in the form of barbed bends of both ends of the cross member according to claim 2 be used by twisting the reinforcement block with respect to the concrete core temperature control module can be connected to this, which is explained below is gone.  

Overall, the reinforcement frame according to the invention offers a simple one Installation and positioning option for concrete core temperature control modules to it also offers adequate protection against floating of the concrete core temperature control modules when pouring concrete, as the concrete core tempering mo dule are securely held on the holding elements on the trestles. The entire con structure and procedure using the reinforcement according to the invention trestles for secure positioning, mounting and buoyancy protection of the concrete core Pereration modules is much easier than in the prior art, since no additional Chen elements or cumbersome handles are required.

Further advantages, features and details of the invention result from the im following described embodiment and with reference to the drawings. there demonstrate:

Fig. 1 is a perspective schematic diagram of an inventive Beweh approximately bocks,

Fig. 2-4 schematic diagrams to illustrate the connection of a reinforcement block with a concrete core temperature control module, and

Fig. 5 is a schematic representation of a concrete ceiling or a concrete floor according to the invention in section.

Fig. 1 shows a reinforcement bracket 1 according to the invention consisting of a trestle frame 2 with a total of three vertical struts 3 , which are connected to each other via horizontally arranged horizontal connecting struts 4 . Via the vertical struts 3 , the reinforcement frame according to the invention is opened onto the formwork and set into a lower reinforcement layer located there, made from the known structural steel mats. On the obe ren connecting struts 4 , the upper reinforcement layer is ultimately also made of the usual steel mesh. In order to be able to attach a concrete core temperature control module in the desired height to the reinforcement bracket 1 , a cross member 5 is provided, which is attached to two vertical struts 3 , preferably welded.

At both ends holding elements 6 are provided in the form of inwardly open bends 7 of the beam ends, in which a concrete core temperature control module can be hung with its carrier mat.

How this hooking takes place is shown in principle in FIGS. 2 to 4.

Fig. 2 shows Betonkerntemperierungsmodul 8 in the form of a partial view with only the support mat 9, a so-called Q-mat is shown. Prefabricated pipelines are usually attached to this in a meandering manner, so that a prefabricated pipe register module results.

The carrier mat 9 consists of mat struts running orthogonally to one another, so that a specific mat grid of generally up to 200 × 200 mm results. The carrier mat 9 can also be a common structural steel mat, for example. In such a mesh grid 10 , the reinforcement trestle according to the invention is now set from above with its vertical struts 3 . It is adjusted until the cross member 5 , which is shorter than the diagonal of the mat grid 10, is passed through it. Subsequently, the reinforcement bracket - see Fig. 3 -, from which, for the sake of clarity, only the cross member 5 is pulled out and the other elements are shown in dashed lines, rotated somewhat, so that the support mat 9 is placed on the cross member 5 from above or he is from below can be pressed. Subsequently, as shown in Fig. 4, the reinforcement bracket 1 is rotated back slightly, the mat struts of the support mat 9 evidently inserted into the holding elements 6 , that is to say the bends, and hung or clamped there.

The reinforcement bracket 1 is thus securely connected to the carrier mat 9 and thus the concrete core temperature control module 8 .

This simple manual procedure is independent of which of the inventions Process variants according to the invention is now always applied the same. It exists the possibility of placing the reinforcement blocks either before inserting the concrete core mounting module in the formwork on the concrete core temperature control module, so that this is put on together with the already fixed reinforcement trestles.  

As an alternative, there is the option of installing the concrete core temperature control module on the lower reinforcement layer, which is already on the formwork, and then the Reinforcement trestles in the mesh grid and after lifting one slightly To fix the concrete core temperature control module in the manner described.

Fig. 5 shows, finally, a concrete slab or a concrete floor 11 according to the invention in the finished cast, however, still located in the formwork state. On a lower formwork level 12 spacers 13 are placed, on which a lower reinforcement layer 14 , usually ordinary structural steel mats, are placed. Regardless of whether the reinforcement brackets are now attached to the concrete core tempering modules before placing the concrete core tempering modules or only afterwards, the reinforcement brackets 1 are in any case on the lower formwork level. On their transverse beams 5 is a Betonkerntemperierungsmodul about the support mat 9 buildin Untitled. Finally, the upper reinforcement layer 15 , primarily also structural steel mesh, lies on the connecting struts 4 of the reinforcement bracket 1 . Then the entire configuration is poured with concrete 16 . After the concrete has hardened, the concrete ceiling or the concrete floor 11 according to the invention is completed.

Apparent runs the Betonkerntemperierungsmodul wherein germatte next to the Trä in Fig. 4 9, the pipes 18, which are attached to the support mat 9, are shown, substantially in the central horizontal plane of the concrete slab or the concrete floor 11. The correct height results automatically from the position of the cross members 5 which are firmly connected to the vertical struts 3 . The position of the upper reinforcement layer 15 is automatically determined by the height of the reinforcement blocks 1 . A reinforcement bracket 1 can therefore be dimensioned according to the desired thickness of a concrete ceiling or a concrete floor.

Since a reinforcement bracket is placed directly on the lower formwork level, the Height of the cross member and thus the location of the concrete core temperature control module as well the height of the upper connecting struts that accommodate the upper reinforcement layer, regardless of the type and height of the lower reinforcement. Especially if the barb-like bends allow the carrier mat to be pinched, there is a firm connection that is difficult to detach at the desired altitude.  

By placing the concrete core temperature control module on the cross beams from above also the accessibility of the concrete core temperature control modules, for example guaranteed during assembly of the upper reinforcement. Also results from the secure mounting on the cross members the float protection during casting ßens. Floating of the concrete core temperature control modules together with the reinforcement jacking is prevented by the weight of the top reinforcement layer. Overall, this is a simple concrete core temperature module assembly possible without additional tools.
