Description

Technical Field

[0001] The utility model belongs to the technical field of precast walls, and particularly relates to a precast wall structure. Background Technique

[0002] An assembled building refers to transferring a large amount of on-site operation work in the traditional construction method to the factory. Building components and fittings, such as floor slabs, wall panels, etc., are processed and manufactured in the factory and transported to the building construction site, and assembled and installed on-site through reliable connection methods. The precast structure is essential in assembled buildings. The precast structure refers to a finished structure prefabricated according to the construction environment in the factory, which is the basic element of assembled buildings and can be directly assembled and used as a wall at the building construction site. The use of precast walls is beneficial to improving the construction speed and saving costs. Precast walls are forming a trend and are gradually applied to buildings;

[0003] When the existing precast walls are in use, it is necessary to align the holes at the bottom of the wall with the steel bars on the ground one by one for splicing, which is difficult to operate. Moreover, the wall is likely to bend the steel bars, and its practicability is not high. At the same time, most precast wall panels are made by pouring cement. If only cement is used for pouring, the strength of the wall structure cannot be guaranteed. Over time, cracks will appear on its surface, greatly reducing the service life of the wall and affecting the safety of the surrounding people. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the objectives, technical solutions and advantages of the technical solutions of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the drawings of the specific embodiments of the present utility model. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0027] Refer to Figures 1-4, an embodiment of the utility model proposes a precast wall structure, which includes a base 1. Through holes 11 are provided on both sides of the base 1. A wall panel 2 is arranged on the base 1. A through hole 21 is horizontally provided at the bottom end of the wall panel 2. The through hole 11 corresponds to the through hole 21. A casting hole 5 is provided on the surface of the base 1. The base 1 has a concave structure with an upward opening. The casting hole 5 is communicated with the internal cavity of the base 1. The wall panel 2 has a convex structure. The bottom of the wall panel 2 is adapted to the concave opening of the base 1. When splicing, the bottom of the wall panel 2 is directly placed into the base 1, so that the bottom of the convex-shaped wall panel 2 can be well engaged into the concave opening of the base 1.

[0028] Referring to Figures 1-4 , a reinforcement component 3 is arranged in the base 1 and the wall panel 2. The reinforcement component 3 includes a number of first reinforcement bars 31 longitudinally penetrating through the wall panel 2 and a second reinforcement bar 32 penetrating through the through hole 21. A reinforcement hole 311 is provided at the bottom end of the first reinforcement bar 31. The reinforcement hole 311 corresponds to the through hole 11 and the through hole 21. The second reinforcement bar 32 passes through the reinforcement hole 311 of the first reinforcement bar 31, so that the second reinforcement bar 32 firmly fixes the wall panel 2 in the base 1 through the first reinforcement bar 31, greatly improving the fastening degree between the wall panel 2 and the base 1. Through the arrangement of the first reinforcement bar 31 and the second reinforcement bar 32, the strength and bearing capacity of the wall panel 2 can be greatly improved.

[0029] Referring to Figures 1-4 , a number of connecting reinforcement bars 4 are also arranged on the wall panel 2. The connecting reinforcement bars 4 are located on the side wall surfaces of the wall panel 2. The connecting reinforcement bars 4 are U-shaped. Through the U-shaped connecting reinforcement bars 4, other steel bars can be wound together with the connecting reinforcement bars 4, so that multiple wall panels 2 can be spliced together.

[0030] The specific implementation method is as follows: During use, hoist the prefabricated concrete wall panel 2 to the platform where installation is required. The wall panel 2 is pre - provided with a first reinforcing steel bar 31 in advance. Place the wall panel 2 into the base 1 on the platform, so that the convex - shaped wall panel 2 can be engaged into the concave - shaped opening of the base 1. Then, pass the second reinforcing steel bar 32 through the first through - hole 11 and the second through - hole 21. When passing through the first through - hole 11 and the second through - hole 21, it will also sequentially pass through the reinforcing holes 311 at the end of the first reinforcing steel bar 31, so that the second reinforcing steel bar 32 firmly fixes the wall panel 2 in the base 1 through the first reinforcing steel bar 31. Then, pour concrete into the first pouring hole 5 so that the space between the bottom of the wall panel 2 and the base 1 is filled with concrete. Then, pour concrete into the first through - hole 11 so that the concrete fills the second through - hole 21 at the bottom of the wall panel 2. Further, after waiting for the concrete to solidify, the purpose of firmly fixing the second reinforcing steel bar 32 and the first reinforcing steel bar 31 can be achieved, so that the entire wall panel 2 can be firmly fixed in the base 1 under the action of the first reinforcing steel bar 31 and the second reinforcing steel bar 32. After installing multiple wall panels 2, build and connect steel bars in the connecting steel bars 4 on both sides of each wall panel 2, so that multiple wall panels 2 are connected to each other. Then, pour concrete at the steel bar connection points so that multiple wall panels 2 are fixed as a whole.
