Description

Technical Field

[0001] The utility model relates to the technical field of pre-embedded bases, in particular to a pre-embedded base for an assembled building wall. Background Art

[0002] Prefabricated construction refers to a construction method that transfers a large amount of on-site work in traditional construction methods to factories, prefabricating components and accessories in the factory and then transporting them to the construction site for assembly and installation.

[0003] When installing existing prefabricated walls, it is necessary to set up a pre-buried pit on the foundation, then pour the base in the pre-buried pit, and finally pour the wall on the base. However, when the existing wall is poured together with the base, in order for the concrete to fully contact the wall and the base, the staff needs to set up multiple isolation mechanisms between the wall and the base to separate the gap between the wall and the base into a gap of a certain length. Before pouring, it is also necessary to use a blocking mechanism to block the gap on both sides of the wall and the base to prevent concrete leakage, which makes pouring troublesome and has poor use effect. In addition, when pre-buried base, only the base is placed in the pre-buried pit and then poured. Due to the gap between the two sides of the base and the pre-buried pit wall, the base is easy to shake during pouring, which causes the base position to shift and the installation effect to be poor. To this end, we propose a pre-buried base for prefabricated building walls. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose an assembled building wall embedded base.

[0005] In order to achieve the above-mentioned object, the present invention adopts the following technical solution: a pre-buried base for an assembled building wall is designed, comprising a support platform, the support platform is pre-buried under the foundation, and the top of the support platform extends above the foundation, a wall is provided on the top of the support platform, and a plurality of positioning steel bars are vertically installed on the top of the support platform, and the tops of the positioning steel bars extend into the interior of the wall;

[0006] Limit baffles are installed on both sides of the top of the support platform. The top of the limit baffle extends above the support platform. The two limit baffles are connected by several partitions, and the bottom of the partition is fixed to the top of the support platform.

There are through holes on both sides of the support platform, and one end of the push rod slides through the corresponding through hole.

[0008] A strip push plate is also provided inside the accommodating groove. The surfaces close to the strip push plate and the strip moving block are provided with inclined surfaces. The two inclined surfaces are in contact and connected. Several grooves are provided on both sides of the top of the support platform. A threaded hole is provided at the bottom of each groove. The bottom of the threaded hole is connected to the accommodating groove, and an adjusting screw is provided inside each threaded hole. The bottom of the adjusting screw is rotatably connected to the strip push plate, and the top of the adjusting screw extends above the threaded hole.

[0009] Preferably, the top of the partition is located between the two limiting baffles.

[0010] Preferably, at least one reinforcing steel bar is installed between two adjacent partitions.

[0011] Preferably, wedge blocks are installed on both sides of each bar-shaped moving block, two wedge guide rails are installed in parallel on both sides of the interior of each accommodating groove, and one end of each wedge block extends into the interior of the corresponding wedge guide rail and slides with the wedge guide rail.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 4 A pre-buried foundation for an assembled building wall includes a support platform 1, which is pre-buried under the foundation, and the top of the support platform 1 extends above the foundation. A wall is provided on the top of the support platform 1, and a plurality of positioning steel bars 3 are vertically installed on the top of the support platform 1. The top of the positioning steel bars 3 extends into the interior of the wall. In the actual installation process, Figure 4 As shown, the bottom of the wall needs to be placed on the support platform 1, and the reserved opening set at the bottom of the wall will be put on the corresponding positioning steel bar 3 to complete the installation. After that, concrete is poured into the reserved opening to fix the wall and the support platform 1 together to complete the assembly.

[0025] like Figure 1 As shown, limit baffles 2 are installed on both sides of the top of the support platform 1, and the top of the limit baffles 2 extends to the top of the support platform 1. The two limit baffles 2 are connected by several partitions 4, and the bottom of the partition 4 is fixed to the top of the support platform 1. During the actual installation process, when the wall is placed on the support platform 1, the bottom of the wall will contact the top of the partition 4, so that a plurality of accommodating cavities will be formed between the bottom of the wall and the several partitions 4 and the limit baffles 2. During pouring, concrete will flow into the accommodating cavities, increasing the connection strength between the wall and the support platform 1, and the gap between the wall and the support platform 1 can be sealed by the partition 4 and the limit baffles 2, so that the concrete will not leak during the pouring process.

[0026] It should be noted that the top of the partition 4 is located between the two limit baffles 2. In this way, when the wall is placed on the top of the partition 4, the top of the limit baffle 2 will extend to both sides of the wall, limiting the wall and preventing the wall from shifting.

[0027] It should be noted that if Figure 4As shown, when the wall is placed on top of the support platform 1, the top of the limit baffle 2 extends above the bottom of the wall, and the adjacent surfaces of the two limit baffles 2 are sealed and connected to both sides of the wall, so that during pouring, concrete will not leak from the gap between the wall and the limit baffle 2.

[0028] like Figure 2 and Figure 3 As shown, a number of receiving grooves 10 are provided on both sides of the bottom of the support platform 1, and a strip-shaped moving block 11 is provided inside each receiving groove 10. A number of push rods 8 are installed on one side of each strip-shaped moving block 11. Through holes 9 are provided on both sides of the support platform 1, and one end of the push rod 8 slides through the corresponding through hole 9. In the actual process of burying the support platform 1, the push rod 8 can be used to support the wall of the pit where the support platform 1 is buried to limit the support platform 1. In this way, when the support platform 1 and the foundation are poured together, the support platform 1 will not shake.

[0029] like Figure 2 and Figure 3 As shown, a strip push plate 12 is further provided inside the accommodating groove 10, and an inclined surface 15 is provided on the adjacent surfaces of the strip push plate 12 and the strip moving block 11, and the two inclined surfaces 15 are in contact and connected. A number of grooves 6 are provided on both sides of the top of the support platform 1, and a threaded hole 16 is provided at the bottom of each groove 6. The bottom of the threaded hole 16 is connected to the accommodating groove 10, and an adjusting screw rod 7 is provided inside each threaded hole 16. The bottom of the adjusting screw rod 7 is rotatably connected to the strip push plate 12, and the top of the adjusting screw rod 7 extends above the threaded hole 16. In actual use, by rotating the adjusting screw rod 7, the adjusting screw rod 7 will drive the strip push plate 12 to move downward under the action of the threaded hole 16. With the cooperation of the two inclined surfaces 15, the strip moving block 11 will be pushed horizontally by the strip push plate 12, thereby causing the top rod 8 to move toward the outside of the support platform 1, against the foundation pit wall, and fix the support platform 1.

[0030] It should be noted that if Figure 3 As shown, wedge blocks 13 are installed on both sides of each bar-shaped moving block 11, and two wedge-shaped guide rails 14 are installed in parallel on both sides of the interior of each accommodating groove 10. One end of each wedge block 13 extends into the corresponding wedge-shaped guide rail 14 and slides with the wedge guide rail 14. With the cooperation of the wedge block 13 and the wedge guide rail 14, the bar-shaped moving block 11 can be limited and guided to keep the bar-shaped moving block 11 stable.

[0031] Specifically, when the present invention is in use, the staff puts the support platform 1 into the pre-buried pit of the foundation, and then turns the adjusting screw rod 7, which will drive the strip push plate 12 to move downward, and the strip push plate 12 pushes the strip moving block 11 to move horizontally through the inclined surface 15, so that one end of the top rod 8 extends out of the through hole 9 and rests on the pit wall, firmly fixing the support platform 1 to prevent the support platform 1 from shaking during pouring. After that, the staff puts the wall on the support platform 1. When placing it, the bottom of the wall will fall on the top of the partition 4, and the top of the limit baffle 2 will move to both sides of the wall, sealing the gap between the wall and the top of the support platform 1, and the partition 4 can divide the gap between the wall and the support platform 1 into multiple accommodating cavities, so that when pouring, the concrete will fully fill the accommodating cavity between the wall and the support platform 1, and the concrete will not leak from the gap between the support platform 1 and the wall.

[0032] Furthermore, Figure 1 As shown, at least one reinforcing steel bar 5 is installed between two adjacent partitions 4. The reinforcing steel bar 5 can increase the structural strength of the partition 4 and prevent the partition 4 from bending and breaking under stress.

[0033] Furthermore, Figure 1 As shown, the outer surface of the push rod 8 is loosely matched with the inner wall of the through hole 9 , so that the push rod 8 will not shake relative to the support platform 1 , thereby improving the fixing effect of the support platform 1 .

[0034] Furthermore, Figure 2 As shown, the end of the push rod 8 away from the strip-shaped moving block 11 is set as a cone surface, so that the end of the push rod 8 can be easily inserted into the foundation pit wall, thereby improving the fixing effect.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
