Description

The utility model relates to the field of construction, namely to the construction of a reinforced concrete wall panel for a pre-fabricated building.

The design of a building reinforced concrete block is known from the prior art, see patent EA 006995 B1, IPC E04B 1/21, E04C 3/34, E04C 3/44, E04B 1/20, E04C 3/20, publ. June 30, 2006, containing two vertical columns and cross beams, rigidly connecting the columns to each other to form a reinforced concrete frame.

The disadvantages of the design described above are the lack of funds for the collapsible connection of blocks, increased labor intensity and increased construction time of the building, due, among other things, to the need to perform concrete work.

A load-bearing wall panel is known from the prior art, see patent RU 160648 U1, IPC E04C 2/296, publ. 03/27/2016, containing a frame in the form of rigidly coupled to each other two steel frames, while the frames are equipped with fastening elements for bolting adjacent wall panels. This solution allows you to reduce the construction time of the building.

The disadvantages of the wall panel known from the patent RU 160648 U1 are associated with the design features.

Fragility - metal is an order of magnitude less durable than reinforced concrete. All surfaces of the metal frame are subject to corrosion, which leads to a decrease in the strength of the building structure.

High cost - a metal structure is several times more expensive than a reinforced concrete structure.

The presence of cold bridges. The frames are bolted together through an insulating gasket that does not prevent cold from entering the panel.

A reinforced concrete wall panel with a crossbar and columns integrated into it is also known from the prior art, see patent RU 2563871 C2, IPC E04B 1/18, publ. September 27, 2015

The disadvantages of the above-described reinforced concrete wall panel are the small glazing area, increased labor intensity and increased construction time of the building, due, among other things, to the need to perform concrete work.

For the closest analogue of the claimed utility model, a reinforced concrete wall panel is taken, see patent US 7958687 B2, IPC E04B 1/04; E04B 1/38; E04B 2/08; E04B 5/02; E04B 7/04; E04B 7/20; E04C 2/04, publ. June 14, 2011

The structure of a reinforced concrete wall panel includes vertical columns connected by transverse beams. Vertical columns and cross-beams are provided with holes for connecting the panel to the floor slabs and adjacent wall panels using threaded elements - "pipe bolts" and nuts.

The disadvantages of the closest analogue are:

- significant time frame for the construction of the building;

- inability to quickly dismantle the building.

The disadvantages listed above are due, in particular, to the need to perform concrete work during the construction of the building.

Other disadvantages of the closest analogue are:

- the inconvenience of the construction and operation of the building, namely the inaccessibility of the locations for the elements of threaded connections;

- limited area of possible glazing.

The task to achieve which the claimed device is directed is to create a reinforced concrete wall panel for the construction of prefabricated prefabricated buildings while maintaining the requirements for the durability and reliability of reinforced concrete buildings, as well as increasing the variety of space-planning architectural solutions implemented with its help.

The technical results to be achieved by the utility model are to reduce the time for erection and dismantling of the building and to increase the convenience of erection, dismantling and operation of the building.

The specified technical results are achieved in a reinforced concrete wall panel, including two columns connected by lower and upper horizontal beams, provided with holes for threaded connection of the panel with floor slabs and other wall panels, as well as provided with holes for laying pipes.

The technical results are achieved by the fact that each column consists of two supports, interconnected by upper and lower bridges, with a technological cavity formed between them and intended for placement and maintenance of pipes and threaded elements connecting the panel with floor slabs and other wall panels, and holes for laying pipes are made in the upper and lower webs of each column.

In this case, at least one horizontal beam can be made in cross-section in the shape of the letter P or G.

In this case, a selection can be made in the lower part of the column for deepening the panel relative to the floor level of the floor slab and placing the outlet of the floor slab in it.

In this case, the column of the wall reinforced concrete panel can be equipped with concrete samples for mechanical adhesion to the thermal insulation material.

The term "support" in this application means a vertically oriented part of the column, which is a load-bearing reinforced concrete bar; each column includes two such rods.

The utility model is illustrated by the following pictures.

The proposed utility model can be implemented as follows.

Column 2 is made of reinforced concrete (see Fig. 3, 4). At the same time, supports 3 are formed in column 2 (see Fig. 4, the area for placing supports 3 is highlighted by filling and dash-dotted lines), which outwardly do not go beyond the column body, but are characterized by the absence of technological holes and provide the bearing capacity of column 2.

The supports 3 are interconnected by the upper 8 and lower 9 jumpers, as well as by the wall 6.

In the column 2, between the supports 3, the bridges and the wall 6, a technological cavity is formed for the placement and maintenance of pipes and threaded elements connecting the panel with floor slabs and other wall panels.

In the lintels 8, 9 of the column 2, coaxial holes 13 of an oval shape are made, intended for laying sewage pipes, heating, water supply, drainage of water from the roof, ventilation and electrical wiring.

In the wall 6 of the column 2, openings 7 are made. The openings 7 are used to access threaded connections that tighten the interfloor wall panels (vertical ties), i.e. concealed installation is provided. The second purpose of the openings 7 is access to the technological cavities, where all communications are located, including the sewage system. A hinged toilet can be attached to the wall 6 of the column 2, in which the opening 7 is located, and the drain can be discharged directly into the sewer pipe, which runs vertically through the oval-shaped holes 13.

Column 2 during manufacture is supplied with embedded parts with fastening holes, as well as reinforcement outlets (reinforcement outlets are not shown in the Fig.).

Regardless of the manufacture of columns 2, the upper 4 and lower 5 reinforced concrete horizontal beams are also made. They are made in the shape of the letter P or G, which allows you to reduce the weight of the beams while maintaining sufficient strength.

An opening 11 is made in the upper beam 4, and an opening 12 is made in the lower beam 5.

Openings 11 and 12 in beams 4,5 serve to access threaded joints that pull wall panels of the same level to each other. This solution makes the installation hidden. Also, through the opening 12 you can get to the location of the threaded connection in the foundation panel, for tightening the foundation slab and the wall panel.

In addition, these technical niches can be used to accommodate heating radiators, recuperators, air conditioners, as well as indoor roller blinds.

All communications passing in the technological channel of the columns of wall panels are brought out into a niche between the wall panel of the first floor and the foundation panel, access to which is provided by the opening 12 on the first floor, and through the channels in the foundation panel they reach the place where the communications enter the building.

After the manufacture of columns 2, upper 4 and lower 5 beams, a reinforced concrete wall panel 1 is produced on the slipway.

On a special slipway, columns 2 are positioned relative to each other with high precision using embedded parts. Using metal embedded parts, shapers (metal molds) are screwed to the columns in such a way that the outlets of the column reinforcement are located in the formed cavities. The upper 4 and lower 5 reinforced concrete beams are also installed on the slipway. Then the cavities are spilled with a concrete solution and left until the concrete hardens, after which the finished reinforced concrete wall panel is removed from the slipway and delivered to the construction site of the building.

The finished reinforced concrete wall panel 1 is used in the construction of reinforced concrete buildings without the use of concrete work. Connections of reinforced concrete panels of wall, foundation, floors are carried out by means of bolted connections and tightening with monostrends. This makes it possible to drastically reduce the terms of erection and dismantling of the building.

The opening in the reinforced concrete wall panel 1 between the columns 2 and the beams 4,5 during the construction of the building, if the wall panel is inside the building, either is not filled at all, or is filled to the thickness of the wall partition. Thus, in the case of no filling, an inner passage panel is obtained. In the case of partial filling, an internal panel is obtained with a solid wall partition (thickness from 8 to 15 cm), or with a doorway.

If a reinforced concrete wall panel is used as an external one, then in the support that is located on the outside of the building, concrete is periodically sampled to a depth necessary to form reliable mechanical adhesion to the thermal insulation material (see Fig. 5). The weakening of the bearing capacity of this support will not affect the strength of the building, because the external load-bearing supports of the columns in this case do not collect the superior load, but only transfer the load from the enclosing and heat-insulating structures to the internal load-bearing column through the column wall of the wall panel.

Fastening of wall reinforced concrete panels to each other is carried out (see Fig. 7, 8, 9):

- using threaded rods 17;

- using the self-centering elements of the reinforced concrete wall panel in the form of pins 15, which also serve to prevent the panels from shifting relative to each other; and

- with the help of monostrends 16, thereby eliminating the work of concrete in tension.

In the reinforced concrete wall panel, all elements of fastening the panels to each other - pins, rods and monostrends - are taken out into the internal easily accessible technological cavities. This contributes to an increase in the convenience of construction, dismantling and operation of the building.

The structure of the column of the wall reinforced concrete panel allows:

1. Using the recess 10 in the lower part, support it on the foundation panel beam in such a way that the lower lintel of the wall panel forms a single floor level with the floors in the building. In this case, the cavity formed by the recess 10 serves to accommodate the beam of the foundation panel there, which ensures the bearing capacity of this beam of the foundation panel when the wall panel is pressed on it;

2. Support on the column of the wall panel both the column of the wall panel of the second floor and the outlet of the floor panel of the second floor - cut 10 in the column of the wall panel allows to place the outlet of the floor slab there.

3. Ensure the transportation of the wall panel in the design position, i.e. enables multiple transportation by attaching the wall panel to the traverse at the sampling point.

4. Use horizontal sampling planes to support bolted connections and monostrends when pulling wall panels together and with the foundation panel beam.

5. Perform the final finishing of the panel on a turnkey basis at the factory.

6. Implement the possibility of building prefabricated reinforced concrete buildings.

7. Carry out a gradual completion of the building already in operation.

The use of the inventive wall reinforced concrete panel allows (see Fig. 10) to carry out the support of the floor slab on the wall reinforced concrete panel with a hinge, without pinching the floor slab. There is also no error incursion from bearing on the floor slab.

By changing the length of the reinforced concrete horizontal beams 4, 5, it is possible to obtain reinforced concrete wall panels of several types.

The design of the reinforced concrete wall panel allows making beams 4, 5, which connect the columns 2, of considerable height, which, in turn, makes it possible to transport them without conductors and increases their strength when calculating for seismic resistance.

The technological cavity in the column 2 between the supports 3, the lintels and the wall 6 can be used for the installation and fastening of the self-supporting end wall panels of the building. In this case, the self-supporting end wall panel 19, an exemplary embodiment of which is shown in FIG. 11, can be equipped with two outboard consoles 20, each of which can be supported on the lower lintel 9 of the column 2 of the corresponding wall reinforced concrete panel 1. The exact relative position of the self-supporting end wall panel 19 and the claimed wall reinforced concrete panel 1 is achieved by connecting through a pin.

The joint of the wall reinforced concrete panel 1 with the self-supporting end wall panel 19 is shown in FIG. 12.

The possibility of using the technological cavity in column 2 for the installation and fastening of self-supporting end wall panels makes it possible to complete the building. In this case, it is enough to outweigh the end wall panel 19 on the reinforced concrete wall panel added in the process of completing the building.

Operation of a reinforced concrete wall panel made in accordance with the declared utility model confirmed the industrial applicability of the utility model and its compliance with the declared technical results.
