Description

Technical Field

[0001] This utility model relates to the field of concrete wall panel technology, specifically modular prefabricated concrete wall panels. Background Technology

[0002] Concrete wall panels are reinforced concrete slab components manufactured in prefabrication plants or on construction sites for use in building assembly. Using prefabricated concrete wall panels to build prefabricated large-panel buildings can improve the degree of factory and mechanized construction, reduce on-site wet work, save on-site labor, overcome seasonal influences, and shorten the construction cycle.

[0003] According to publication number CN222275925U, a precast concrete wall panel includes a reinforced concrete wall body. The left and right sides of the reinforced concrete wall body are respectively provided with recessed pouring areas. Multiple layers of butt-joint reinforcing steel rings with closed-loop structures are pre-embedded on the left and right sides of the reinforced concrete wall body. At least a portion of the butt-joint reinforcing steel rings protrudes from the reinforced concrete wall body and is located within the pouring areas. A grout-blocking plate is formed on the outer part of the reinforced concrete wall body at the pouring area. This utility model facilitates quick and reliable connection with adjacent walls, and assembly is simple and reliable. Because a grout-blocking plate is formed on the outer part of the pouring area, scaffolding and formwork sealing are not required on the outer side of the wall during pouring operations; only the inner side of the wall needs to be sealed with formwork. This greatly reduces the workload of on-site scaffolding erection and formwork dismantling, significantly improves construction efficiency, and shortens the construction cycle.

[0004] The connection between wall panels can be achieved through the above-mentioned rebar rings and other structures. However, after the connection is completed, the connection stability is poor because it is only connected by rebar. Separation is likely to occur during the grouting process, which will affect the assembly effect. Utility Model Content

[0005] The purpose of this utility model is to provide modular prefabricated concrete wall panels to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular prefabricated concrete wall panel, comprising a concrete wall panel with symmetrically formed grooves on both sides, and multiple pre-embedded holes inside the grooves. Two connecting plates are symmetrically arranged on one side of the concrete wall panel, forming a casting reserved area between the two connecting plates and the concrete wall panel. The connecting plates are located inside the grooves, and slots are formed on the side of the connecting plates closest to the concrete wall panel. Expansion screws are provided between the connecting plates and the pre-embedded holes.

[0007] As a further preferred embodiment of this technical solution, two connecting plates are symmetrically arranged on the side of the concrete wall panel away from the first connecting plate. An insert plate is fixedly connected to the side of the connecting plate away from the concrete wall panel. The insert plate and the slot are compatible. An expansion screw is provided between the connecting plate and the pre-embedded hole.

[0008] As a further preferred embodiment of this technical solution, the concrete wall panel is provided with a plurality of transverse steel bars in the vertical direction, the transverse steel bars penetrating the concrete wall panel and forming connecting steel bar rings on both sides.

[0009] As a further preferred embodiment of this technical solution, multiple longitudinal steel bars are symmetrically welded to both sides of the interior of the transverse steel bars, and the longitudinal steel bars and transverse steel bars constitute a steel cage.

[0010] As a further preferred embodiment of this technical solution, the concrete wall panel has multiple symmetrically provided interfaces on its upper and lower sides, and the interfaces are compatible with the longitudinal reinforcing bars.

[0011] As a further preferred embodiment of this technical solution, the concrete wall panel is provided with a thermal insulation layer inside, which is located between the longitudinal and transverse reinforcing bars, and the thermal insulation layer is made of rock wool and polystyrene foam.

[0012] As a further preferred embodiment of this technical solution, the bottom of the concrete wall panel is provided with a pre-embedded grouting groove, and multiple grouting ports are symmetrically provided on both sides of the bottom of the concrete wall panel, the grouting ports and the pre-embedded grouting groove forming a grouting channel.

[0013] This utility model provides a modular prefabricated concrete wall panel, which has the following beneficial effects:

[0014] (1) This utility model uses the mounting holes and pre-embedded holes on the connecting plate 1 and the connecting plate 2 to correspond, and uses expansion screw 1 and expansion screw 2 to fix the connecting plate 1 and the connecting plate 2 to the concrete wall panel. When assembling the two concrete wall panels, the insert plate is inserted into the slot. Since the size of the insert plate and the slot are compatible, the two concrete wall panels are limited to ensure the connection stability after assembly.

[0015] (2) This utility model sets multiple transverse and longitudinal steel bars inside the concrete wall panel and uses the transverse and longitudinal steel bars to form a steel cage. After the concrete wall panel is made, the steel cage enhances the tensile and bending resistance of the wall panel. In addition, a thermal insulation layer is set inside the steel cage, which can improve the energy efficiency of the building and increase the thermal insulation effect of the concrete wall panel.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, the modular prefabricated concrete wall panel includes a concrete wall panel 1. The concrete wall panel 1 has grooves 2 symmetrically opened on both sides. Multiple pre-embedded holes 3 are opened inside the grooves 2. Two connecting plates 4 are symmetrically arranged on one side of the concrete wall panel 1. A casting reserved area 7 is formed between the two connecting plates 4 and the concrete wall panel 1. The connecting plates 4 are located inside the grooves 2. A slot 5 is opened on the side of the connecting plates 4 near the concrete wall panel 1. An expansion screw 6 is provided between the connecting plates 4 and the pre-embedded holes 3.

[0023] Two connecting plates 8 are symmetrically arranged on the side of the concrete wall panel 1 away from the connecting plate 4. A plug plate 9 is fixedly connected to the side of the connecting plate 8 away from the concrete wall panel 1. The plug plate 9 and the slot 5 are compatible. An expansion screw 10 is provided between the connecting plate 8 and the pre-embedded hole 3.

[0024] Align the insert plate 9 on the second connecting plate 8 with the slot 5 on the first connecting plate 4, and align the mounting holes and pre-embedded holes 3 on the second connecting plate 8 and the first connecting plate 4 with each other. Use expansion screws 1-6 and 2-10 to fix the first connecting plate 4 and the second connecting plate 8 to the concrete wall panel 1. The cooperation of the insert plate 9 and the slot 5 can restrict the movement between the two concrete wall panels 1 to ensure the stability of the connection after assembly. After the first connecting plate 4 and the second connecting plate 8 are installed, a top-opening pre-casting area 7 can be formed between them and the concrete wall panel 1. Pouring grout into it can prevent the leakage of adhesive. After the grout solidifies, the assembly of the concrete wall panel 1 can be completed.

[0025] Multiple transverse steel bars 11 are arranged vertically inside the concrete wall panel 1. The transverse steel bars 11 penetrate the concrete wall panel 1 and form connecting steel bar rings 13 on both sides.

[0026] Multiple longitudinal steel bars 12 are symmetrically welded to both sides of the interior of the transverse steel bar 11. The longitudinal steel bars 12 and the transverse steel bars 11 form a steel cage.

[0027] Multiple transverse steel bars 11 and longitudinal steel bars 12 are set inside the concrete wall panel 1, and a steel cage is formed by the transverse steel bars 11 and longitudinal steel bars 12. Thus, after the concrete wall panel 1 is made, the tensile and bending resistance of the wall panel is enhanced by the steel cage.

[0028] Multiple joints 15 are symmetrically provided on the upper and lower sides of the concrete wall panel 1, and the joints 15 are compatible with the longitudinal steel bars 12.

[0029] The interior of the concrete wall panel 1 is provided with a thermal insulation layer 14, which is located between the longitudinal steel bars 12 and the transverse steel bars 11. The thermal insulation layer 14 is made of rock wool and polystyrene foam.

[0030] An insulation layer 14 is installed inside the steel cage, which can improve the building's energy efficiency and increase the insulation effect of the concrete wall panel 1.

[0031] A pre-embedded grouting groove 16 is provided at the bottom of the concrete wall panel 1, and multiple grouting ports 17 are symmetrically provided at the bottom of both sides of the concrete wall panel 1. The grouting ports 17 and the pre-embedded grouting groove 16 form a grouting channel.

[0032] This utility model provides a modular prefabricated concrete wall panel, the specific working principle of which is as follows:

[0033] In use, the concrete wall panel 1 is inserted into the pre-drilled hole in the base through the longitudinal reinforcing bar 12. Grout is injected into the pre-embedded grouting groove 16 through the grouting port 17. After the grout solidifies, the concrete wall panel 1 can be fixed to the base. Using a hoisting tool, another concrete wall panel 1 is moved to the installation position, so that the connecting reinforcing bar ring 13 on the concrete wall panel 1 and the connecting reinforcing bar ring 13 on the original concrete wall panel 1 are staggered and in contact with each other. The hoisting tool moves the concrete wall panel 1 downward, and the connecting reinforcing bar ring 13 on the concrete wall panel 1 moves inside the connecting reinforcing bar ring 13 on the original concrete wall panel 1, until the two concrete wall panels 1 are aligned. The top of the concrete wall panel 1 is flush with the base, and the longitudinal steel bar 12 is inserted into the reserved hole of the base. The concrete wall panel 1 is fixed to the base in the same way. The insert plate 9 on the connecting plate 2 8 and the slot 5 on the connecting plate 1 4 are aligned, and the mounting holes on the connecting plate 2 8 and the connecting plate 1 4 are aligned with the pre-embedded holes 3. The connecting plate 1 6 and the connecting plate 2 10 are used to fix the connecting plate 1 4 and the connecting plate 2 8 to the concrete wall panel 1. The movement between the two concrete wall panels 1 can be restricted by the cooperation of the insert plate 9 and the slot 5. The connecting plate 1 4 and the connecting plate 2 8 form a reserved area for pouring. Grout is poured into it and the assembly of the concrete wall panel 1 is completed after solidification.
