Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a prefabricated concrete frame structure. Background Art

[0002] Usually, when installing pipes through walls, holes need to be drilled in the wall. Drilling holes in a built wall has the following disadvantages: (1) Drilling holes in a built wall can easily disturb the wall structure, affecting the overall stability of the wall and causing waste of materials. (2) During the drilling process, noise and dust pollution will be caused. At the same time, a large amount of construction waste will be generated, increasing the workload of subsequent cleaning, resulting in low work efficiency and failing to meet the green and environmentally friendly construction concept. (3) The holes drilled are large in size and irregular in shape, which increases the need for subsequent hole repair processes. Utility Model Content

[0003] The utility model aims to provide a prefabricated concrete frame structure to solve the problems of poor overall stability of the wall, material waste, noise pollution, dust pollution, heavy workload, low work efficiency and complicated working procedures.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a precast concrete frame structure, including a precast concrete block, the precast concrete block is provided with a receiving hole, the receiving hole is used to install a pipe, the lower side, left side and right side of the precast concrete block are provided with a plurality of No. 1 reinforcement grooves, the No. 1 reinforcement grooves are in the shape of a positive cone, and the upper side of the precast concrete block is provided with a plurality of No. 2 reinforcement grooves, the No. 2 reinforcement grooves are in the shape of an inverted cone.

[0005] The beneficial effect of this solution is: this technical solution uses prefabricated concrete blocks, so that when wall construction is carried out, the concrete prefabricated blocks and wall construction are carried out simultaneously, that is, the concrete prefabricated blocks are directly built on the wall, and when installing pipes, the pipes can be directly passed through the accommodating holes.

[0006] When installing pipes, this technical solution does not need to drill holes in the built walls, will not cause disturbance to the walls, and will not affect the overall stability of the walls. At the same time, it will not waste materials, cause noise and dust pollution, or generate construction waste due to drilling holes. It meets the green and environmentally friendly construction concept, and can reduce workload and improve work efficiency.

[0007] The precast concrete blocks of the present technical solution can be mass-produced according to the size and shape of the pipeline, thus realizing the factory production of the precast concrete blocks. The precast concrete blocks have the advantages of simple and quick construction, which can significantly improve work efficiency and at the same time meet the installation quality of the pipeline.

[0008] Since the pipes will rub against the side walls of the receiving hole when installing the pipes, the connection position between the precast concrete block and the wall is prone to loosening. However, the technical solution sets the No. 1 reinforcement groove and the No. 2 reinforcement groove. When the precast concrete block and the wall are built simultaneously, the concrete can flow into the No. 1 reinforcement groove and the No. 2 reinforcement groove, thereby improving the connection strength between the precast concrete block and the wall and making it less likely for the connection position between the precast concrete block and the wall to loosen.

[0009] The technical solution sets the No. 1 reinforcement groove into a positive cone shape, so that the concrete can easily fill the No. 1 reinforcement groove, thereby improving the connection strength between the precast concrete block and the wall; the technical solution sets the No. 2 reinforcement groove into an inverted cone shape, so that the concrete on the upper side of the precast concrete block can easily fill the No. 2 reinforcement groove under the action of gravity. At the same time, since the inner aperture of the No. 2 reinforcement groove is larger than the outer aperture, the solidified concrete is not easy to be pulled out of the No. 2 reinforcement groove, thereby further improving the connection strength between the precast concrete block and the wall.

[0010] Furthermore, a number of No. 1 annular grooves are provided on the inner wall of the No. 1 reinforcement groove, and a number of No. 2 annular grooves are provided on the inner wall of the No. 2 reinforcement groove.

[0011] The beneficial effect of this solution is as follows: due to the setting of the No. 1 annular groove and the No. 2 annular groove, when the concrete in the No. 1 reinforcement groove and the No. 2 reinforcement groove solidifies, the solidified concrete will engage with the No. 1 annular groove and the No. 2 annular groove, thereby restraining the solidified concrete, reducing the possibility of the solidified concrete in the No. 1 annular groove and the No. 2 annular groove being pulled out, and further improving the connection strength between the concrete precast block and the wall.

[0012] Furthermore, a steel mesh is provided inside the prefabricated concrete block.

[0013] The beneficial effect of this solution is that due to the provision of the steel mesh, this technical solution can improve the strength of the precast concrete blocks and prevent the precast concrete blocks from being deformed.

[0014] Furthermore, a waterproof layer is provided on the side of the receiving hole.

[0015] The beneficial effect of this solution is that due to the provision of the waterproof layer, this technical solution can prevent the wall from being affected by moisture and affecting the pipeline, thereby shortening the service life of the pipeline.

[0016] Furthermore, the diameter of the large diameter end of the No. 2 reinforcement groove is 1.3-1.5 times the diameter of the small diameter end.

[0017] The beneficial effect of this solution is: this technical solution sets the diameter of the large diameter end of the No. 2 reinforcement groove to 1.3-1.5 times the diameter of the small diameter end, so that concrete can smoothly enter the No. 2 reinforcement groove, fill the No. 2 reinforcement groove and the No. 2 annular groove, and prevent the formation of voids in the No. 2 reinforcement groove and the No. 2 annular groove.

[0018] Furthermore, the diameter of the minor diameter end of the No. 2 reinforcement groove is 3cm-4cm.

[0019] The beneficial effects of this solution are as follows: this technical solution sets the diameter of the small diameter end of the No. 2 reinforcement groove to 3cm-4cm, so that concrete can easily enter the No. 2 reinforcement groove and fill the No. 2 reinforcement groove, thereby improving the connection strength between the concrete precast block and the wall.

[0021] Figure 2 It is a longitudinal cross-sectional view of a prefabricated concrete frame structure of the utility model. DETAILED DESCRIPTION

[0022] The following is further described in detail through specific implementation methods:

[0023] The reference numerals in the drawings of the specification include: precast concrete block 1, receiving hole 2, waterproof layer 3, No. 1 reinforcement groove 4, No. 1 annular groove 5, No. 2 reinforcement groove 6, No. 2 annular groove 7.

[0024] Example

[0025] like Figure 1 A precast concrete frame structure shown includes a precast concrete block 1, a front side of the precast concrete block 1 is provided with a through receiving hole 2, the receiving hole 2 is used to install a pipe, and a waterproof layer 3 is sprayed on the side wall of the receiving hole 2. Due to the provision of the waterproof layer 3, it is possible to prevent the wall from being affected by moisture and affecting the pipe, thereby shortening the service life of the pipe; a steel mesh is cast inside the precast concrete block 1. Due to the provision of the steel mesh, the strength of the precast concrete block 1 can be improved and the precast concrete block 1 can be prevented from being deformed. In this embodiment, the receiving hole 2 is a circular hole, but it is not limited thereto. The receiving hole 2 can be designed into different shapes according to actual needs.

[0026] like Figure 2As shown, four No. 1 reinforcing grooves 4 are provided on the lower side, left side and right side of the concrete prefabricated block 1. The No. 1 reinforcing grooves 4 are in a positive cone shape. The diameter of the No. 1 reinforcing grooves 4 increases successively on the side close to the accommodating hole 2. Two No. 1 annular grooves 5 are provided on the inner wall of the No. 1 reinforcing grooves 4. Due to the provision of the No. 1 reinforcing grooves 4, on the one hand, the weight of the concrete prefabricated block 1 can be reduced, which is convenient for the installation of the concrete prefabricated block 1 and is also convenient for the staff to carry. On the other hand, due to the No. 1 reinforcing grooves 4 being in a positive cone shape, when the concrete prefabricated block 1 is synchronously built with the wall, the concrete at the bottom, left side and right side of the concrete prefabricated block 1 can flow more easily into the No. 1 reinforcing grooves 4, thereby improving the connection strength between the concrete prefabricated block 1 and the wall. By providing the No. 1 annular grooves 5 on the inner wall of the No. 1 reinforcing grooves 4, the concrete is meshed with the No. 1 annular grooves 5 after solidification. The No. 1 annular grooves 5 play a role in restraining the solidified concrete, reducing the possibility of the concrete in the No. 1 reinforcing grooves 4 being pulled out, thereby further improving the connection strength between the concrete prefabricated block 1 and the wall.

[0027] like Figure 2As shown, four No. 2 reinforcing grooves 6 are opened on the upper side of the concrete prefabricated block 1, and the No. 2 reinforcing grooves 6 are in the shape of an inverted cone. The diameter of the No. 2 reinforcing grooves 6 decreases gradually towards the side close to the accommodating hole 2. The diameter of the large diameter end of the No. 2 reinforcing groove 6 is 1.3-1.5 times the diameter of the small diameter end, and the diameter of the small diameter end of the No. 2 reinforcing groove 6 is 3cm-4cm. Two No. 2 annular grooves 7 are opened on the inner wall of the No. 2 reinforcing groove 6; due to the provision of the No. 2 reinforcing groove 6, on the one hand, the weight of the concrete prefabricated block 1 can be reduced, which is convenient for the installation of the concrete prefabricated block 1, and at the same time, it is also convenient for the staff to carry it. On the other hand, due to the No. 2 reinforcing groove 6 in the shape of an inverted cone, when the concrete prefabricated block 1 is synchronously built with the wall, the concrete can enter the No. 2 reinforcing groove 6 under the action of gravity and fill the No. 2 reinforcing groove 6, and the diameter inside the No. 2 reinforcing groove 6 is 1.3-1.5 times the diameter of the small diameter end. The diameter of the small diameter end of the No. 2 reinforcing groove 6 is 3cm-4cm. The diameter is large and the diameter is small on the side close to the wall, so that the concrete solidified in the No. 2 reinforcement groove 6 is not easy to be pulled out from the No. 2 reinforcement groove 6. Therefore, the connection strength between the concrete precast block 1 and the wall can be improved. By arranging the No. 2 annular groove 7 on the inner wall of the No. 2 reinforcement groove 6, the concrete is engaged with the No. 2 annular groove 7 after solidification. The No. 2 annular groove 7 plays a role in restraining the solidified concrete, reducing the possibility of the concrete in the No. 2 reinforcement groove 6 being pulled out, and further improving the connection strength between the concrete precast block 1 and the wall. By setting the diameter of the large diameter end of the No. 2 reinforcement groove 6 to 1.3-1.5 times the diameter of the small diameter end, the diameter of the small diameter end of the No. 2 reinforcement groove 6 is 3cm-4cm, so that the concrete can smoothly enter the No. 2 reinforcement groove 6, and at the same time, the No. 2 reinforcement groove 6 and the No. 2 annular groove 7 can be filled. In this embodiment, the diameter of the large diameter end of the No. 2 reinforcement groove 6 is 1.3 times the diameter of the small diameter end, and the diameter of the small diameter end of the No. 2 reinforcement groove 6 is 4 cm. It should be noted that the number of the No. 1 reinforcement groove 4 and the No. 2 reinforcement groove 6 are both four, and the number of the No. 1 annular groove 5 and the No. 2 annular groove 7 are both two, but this is not limited to it. The number of the No. 1 reinforcement groove 4, the No. 2 reinforcement groove 6, the No. 1 annular groove 5 and the No. 2 annular groove 7 can be increased or decreased according to actual needs.
