Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, specifically relating to a prefabricated wall. Background Technology

[0002] Precast walls, also known as prefabricated walls, can be mass-produced in factories and then transported to the site for assembly. Precast walls are widely used in the construction industry due to their advantages such as low cost and convenient and quick construction.

[0003] Existing prefabricated walls are usually installed and positioned by hoisting. In order to improve the stability of the prefabricated wall, the steel bars of the wall and the column are connected. Anchor bars are pre-embedded in the wall. Before the wall is hoisted and positioned, the anchor bars need to be bent to avoid the anchor bars interfering with the installation of the wall. That is, the anchor bars make way for the steel bars of the column. After the wall is installed in the designated position, the workers need to manually bend the anchor bars to restore the anchor bars to their original position and make them abut against the steel bars of the column.

[0004] However, in actual use, the anchor bars have high strength and some are located at high positions. Bending them manually is labor-intensive and not conducive to practical use. Utility Model Content

[0005] The present invention aims to provide a prefabricated wall to solve the problem mentioned above that the installation and positioning of existing prefabricated walls is relatively labor-intensive.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precast wall, comprising...

[0007] The wall body has a protruding part on its side wall, and the side wall of the protruding part has embedded steel bars, the axis of which is parallel to the thickness direction of the wall body.

[0008] An anchoring assembly includes an mounting plate and anchor bars. The mounting plate has mounting holes adapted to the pre-embedded reinforcing bars. The mounting plate is connected to a protrusion, and the outer wall of the mounting plate is flush with the side wall of the wall body. The anchor bars are fixed to the mounting plate.

[0009] The principle and effects of this technical solution:

[0010] 1. By installing the anchor bars onto the mounting plate, the anchor bars are separated from the wall body. This allows for the separate installation of the wall body and the mounting plate. The installation positioning of the wall body is not limited by the anchor bars or column reinforcement. Furthermore, by installing the mounting plate on the protruding part, the anchor bars can abut against the column reinforcement during the installation of the mounting plate, thus limiting the position of the wall body. This avoids the need for manual bending of the reinforcement, saving manpower and improving installation efficiency, making installation faster and more convenient.

[0011] 2. By setting up pre-embedded steel bars, the mounting plate is more capable of withstanding lateral forces, which means that the stability between it and the protrusion is stronger.

[0012] The present invention is further configured such that: the anchoring assembly also includes a connecting screw and a connecting nut, the connecting screw is slidably inserted into the mounting plate and the wall body respectively, and the two ends of the connecting screw are respectively threaded onto the connecting nut, the connecting nut abutting against the outer wall of the mounting plate.

[0013] The principle and effect of this technical solution: By aligning the mounting holes of the mounting plate with the pre-embedded reinforcing bars, the mounting plate can be abutted against the protrusion. The mounting plate and the protrusion are connected and limited by the connecting screw and the connecting nut, so that the mounting plate and the protrusion can be stably abutted together. The connecting screw restricts the movement of the mounting plate along the side of the column's reinforcing bars, and the connecting nut restricts the mounting plate from moving away from the protrusion.

[0014] The present invention is further configured such that: the side of the mounting plate near the protrusion has a grouting groove, and the pre-embedded steel bars and connecting bolts pass through the grouting groove respectively.

[0015] The principle and effect of this technical solution: By setting up the grouting groove, the mounting plate and the protrusion are connected by connecting screws and connecting nuts. Cement can also be poured into the grouting groove during column casting. By filling the grouting groove with cement, the embedded steel bars, the protrusion, the mounting plate and the connecting screws are formed into a whole under the filling of cement, thereby further enhancing the stability between the mounting plate and the protrusion.

[0016] The present invention is further configured such that: the side wall of the protrusion has reinforcing ribs, the reinforcing ribs are adapted to the grouting groove, and there is a grouting cavity between the reinforcing ribs and the grouting groove.

[0017] The principle and effect of this technical solution: By setting reinforcing ribs, the load-bearing capacity of the protrusion is improved, and the fit between the protrusion and the mounting plate is strengthened, thereby improving the stability of the mounting plate.

[0018] The present invention is further configured such that the top of the grouting cavity is connected to the outside, and the bottom surface of the grouting cavity is higher than the bottom surface of the wall body.

[0019] The principle and effect of this technical solution: By connecting the top of the grouting cavity with the outside, the grouting cavity can be poured from the top of the wall body during the grouting process. The bottom sealing design prevents cement from flowing out from the gaps on the bottom surface, reducing the impact of cement pouring on the outside environment, and making the pouring process quick and convenient.

[0020] The present invention is further configured such that: the top of the wall body has a positioning steel bar, and the bottom of the wall body has a positioning hole adapted to the positioning steel bar.

[0021] The principle and effect of this technical solution: By setting up positioning steel bars and positioning holes, the top of the wall body can be positioned and connected by positioning steel bars when installing the wall body or the top floor slab, thereby improving the connection strength between the upper wall body or the top floor slab and the lower wall body.

[0022] The present invention is further configured such that: the interior of the mounting plate has a reinforced concrete structure, and the ends of the anchor bars are anchored to the interior of the mounting plate.

[0023] The principle and effect of this technical solution are as follows: By making the interior of the mounting plate have a reinforced concrete structure, the strength of the mounting plate is the same as that of the wall body, thus increasing the service life of the mounting plate. Furthermore, by anchoring the anchor bars inside the mounting plate, the connection strength between the anchor bars and the mounting plate is improved. Attached Figure Description

[0033] Example:

[0034] As attached Figure 1-4 As shown, this utility model discloses a precast wall, including a wall body 110 and an anchoring assembly. The left and right side walls of the wall body 110 are respectively provided with protrusions 120. Both the wall body 110 and the protrusions 120 are made of reinforced concrete. The front and rear side walls of the protrusions 120 are respectively provided with reinforcing ribs 121. The protrusions 120 are pre-embedded with pre-embedded steel bars 130. The two ends of the pre-embedded steel bars 130 pass through the reinforcing ribs 121 on both sides respectively. The axial direction of the pre-embedded steel bars 130 is parallel to the thickness direction of the wall body 110. The top of the wall body 110 is provided with positioning steel bars 140, which are pre-embedded in the wall body 110. The bottom of the wall body 110 is provided with positioning holes (not shown in the figure) that are adapted to the positioning steel bars 140.

[0035] Multiple sets of anchoring components are provided, and the anchoring components are respectively provided on both sides of a protrusion 120. The anchoring components include an installation plate 210, an anchoring bar 220, a connecting screw 230 and a connecting nut 240. The interior of the installation plate 210 has a reinforced concrete structure, and the end of the anchoring bar 220 is anchored to the interior of the installation plate 210. The side of the installation plate 210 near the protrusion 120 has a grouting groove 212. The reinforcing bar 121 is adapted to the grouting groove 212, and there is a grouting cavity 250 between the reinforcing bar 121 and the grouting groove 212. The top of the grouting cavity 250 is connected to the outside, and the bottom surface of the grouting cavity 250 is higher than the bottom surface of the wall body 110.

[0036] The mounting plate 210 has mounting holes 211 that are compatible with the pre-embedded steel bars 130. The connecting screws 230 are slidably inserted into the mounting plate 210 and the wall body 110 respectively. The two ends of the connecting screws 230 are threaded onto the connecting nuts 240. The connecting nuts 240 abut against the outer wall of the mounting plate 210, and the outer wall of the mounting plate 210 is flush with the side wall of the wall body 110. The pre-embedded steel bars 130 and the connecting screws 230 pass through the grouting groove 212 respectively. The cross-section of the anchor bar 220 is L-shaped.

[0037] The specific implementation process is as follows:

[0038] During installation, the positioning holes of the wall body 110 are aligned with the exposed reinforcing bars on the bottom surface using a hoisting method, thus placing the wall body 110 on the ground (or installing it on the lower floor slab). Then, the mounting plate 210 is hoisted to align with the protrusion 120, at which point the anchor bar 220 aligns with the column reinforcing bar 310. The mounting plate 210 is then fitted onto the embedded reinforcing bar 130, and the anchor bar 220 moves to abut against the column reinforcing bar 310. After the mounting plate 210 is in place, it is connected by the connecting bolt 230 and the connecting nut 240. The mounting plate 210 is positioned relative to the wall, allowing it to be stably placed on the wall. This process eliminates the need for manual bending of the reinforcing bars, saving manpower. Furthermore, the installation of the mounting plate 210 and the anchoring bars 220 relative to the column reinforcing bars 310 is quick and convenient. The column reinforcing bars 310 are fitted with stirrups 320. After installation, the column reinforcing bars 310 need to be cast (casting the column). During casting, the grouting cavity 250 is also cast simultaneously, thereby ensuring that the mounting plate 210 is stably fixed to the protrusion 120 and the wall body 110. The construction steps are simple and convenient.
