Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an intermittent expansion reinforcement belt positioning device. Background Technology

[0002] Expansion reinforcement strips are a technical measure that reduces or eliminates post-cast strips and expansion joints and extends the continuous casting length of components by pouring shrinkage-compensating concrete at the pre-set post-cast strip location in the structure. Intermittent expansion reinforcement strips refer to the concrete at the expansion reinforcement strip location being poured simultaneously with the concrete on one side, while the other side is a construction joint.

[0003] The concrete in the expansion reinforcement zone needs to be separated from the adjacent concrete on one side by a dense wire mesh. The main purpose is to control the free expansion of the expansion concrete, ensure its directional compensation for shrinkage, and at the same time guarantee the integrity and durability of the structure.

[0004] Traditional positioning of dense wire mesh involves welding the dense wire mesh inside a metal frame, then binding the metal frame with wire to fix it to the rebar frame to achieve positioning of the dense wire mesh. The wire binding requires a lot of manual labor, and the operation is difficult due to the limited space, which affects the positioning efficiency of the dense wire mesh and the construction period. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an intermittent expansion reinforcement belt positioning device, which has the advantages of quickly positioning dense wire mesh, thereby improving positioning efficiency and accelerating the construction period. It solves the problem that traditional dense wire mesh positioning requires a lot of manual operation and is difficult to operate due to the limited space, thus affecting the positioning efficiency of dense wire mesh and the construction period.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An intermittent expansion reinforcing belt positioning device includes an angle iron frame, a dense wire mesh, a water-stop steel plate and an assembly column. The angle iron frame is provided with a dense wire mesh inside. The top and bottom walls of the inner frame of the angle iron frame are provided with strip-shaped holes that are distributed horizontally at equal intervals. The surface of the water-stop steel plate is provided with connecting holes that are adapted to the strip-shaped holes.

[0007] The angle iron frame is distributed vertically, the water-stop steel plate is located between the angle iron frames, and the strip-shaped hole is connected to the corresponding connecting hole by the same bolt.

[0008] The rear side of the assembly column is fixedly connected to a frame plate distributed vertically. A short rod adapted to the strip hole is fixedly connected to the opposite side of the frame plate. The top of the assembly column is rotatably connected to a bolt head screw extending into it. A locking assembly is provided on the outside of the bolt head screw, which is drivenly connected to it and extends to the rear side of the assembly column.

[0009] The beneficial effects of this utility model are:

[0010] This intermittent expansion reinforcement positioning device places the angle iron frame on top of the bottom rebar frame. By moving the assembly column, the short rod moves within the strip-shaped hole until the locking component aligns with the bottom rebar frame. An electric wrench rotates the bolt head screw, which in turn moves the locking component upward until the bottom rebar frame is clamped between the locking component and the angle iron frame. A water-stop steel plate is placed on top of the angle iron frame, and another angle iron frame is placed on top of the water-stop steel plate, aligning the strip-shaped hole with the connecting hole. Then, bolts are used to fix the lower angle iron frame, water-stop steel plate, and upper angle iron frame together. The top rebar frame is then laid on top of the upper angle iron frame, and the operation is the same as fixing the lower angle iron frame to the bottom rebar frame. By fixing the upper angle iron frame to the top rebar frame, the positioning of the dense wire mesh is completed. This device offers the advantages of quick positioning of dense wire mesh, thereby improving positioning efficiency and accelerating the construction period.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, a rectangular hole communicating with the interior is provided on the rear side of the assembly column;

[0013] Furthermore, the locking assembly includes an internally threaded cylinder, a support rod, a T-shaped support plate, and a locking groove. The outer side of the bolt head screw is threadedly connected to an internally threaded cylinder located inside the assembly column. The rear side of the internally threaded cylinder is fixedly connected to a support rod extending through a rectangular hole to its rear side. The top of the rear end of the support rod is fixedly connected to a T-shaped support plate, and the top of the T-shaped support plate has a locking groove adapted to the reinforcing bar.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the steel reinforcement frame is located between the T-shaped frame piece and the angle iron frame, and any locking groove is aligned with the steel reinforcement frame. The bolt head screw is rotated by an electric wrench. Since the internal threaded cylinder is threadedly connected to the bolt head screw, the internal threaded cylinder is driven to move axially in the assembly column. Thus, the T-shaped frame piece is driven by the frame rod to clamp the steel reinforcement frame between the locking groove and the angle iron frame. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the embodiments, by Figure 1-5 The present invention provides an intermittent expansion reinforcement belt positioning device, comprising an angle iron frame 1, a dense wire mesh 2, a water-stop steel plate 3, and an assembly column 6. The angle iron frame 1 is provided with a dense wire mesh 2 inside. The top and bottom walls of the inner frame of the angle iron frame 1 are provided with horizontally equidistant strip holes 4. The surface of the water-stop steel plate 3 is provided with connecting holes 5 that are adapted to the strip holes 4.

[0023] The rear side of the assembly column 6 is fixedly connected to a frame plate 7 distributed vertically. A short rod 8 adapted to the strip hole 4 is fixedly connected to the opposite side of the frame plate 7. A bolt head screw 9 extending into the top of the assembly column 6 is rotatably connected. A locking assembly 10 is provided on the outside of the bolt head screw 9 and is connected to it in a transmission manner and extends to the rear side of the assembly column 6.

[0024] A rectangular hole 11 communicating with the interior is provided on the rear side of the assembly column 6;

[0025] The locking assembly 10 includes an internally threaded cylinder 101, a support rod 102, a T-shaped support plate 103, and a locking groove 104. The outer side of the bolt 9 is threadedly connected to the internally threaded cylinder 101 located inside the assembly column 6. The rear side of the internally threaded cylinder 101 is fixedly connected to the support rod 102, which extends to the rear side through the rectangular hole 11. The top of the rear end of the support rod 102 is fixedly connected to the T-shaped support plate 103. The top of the T-shaped support plate 103 is provided with a locking groove 104 that is adapted to the reinforcing bar.

[0026] Position the rebar frame between the T-shaped frame 103 and the angle iron frame 1, and align any one of the locking grooves 104 with the rebar frame. Use an electric wrench to rotate the bolt head screw 9. Since the internal threaded cylinder 101 is threadedly connected to the bolt head screw 9, the internal threaded cylinder 101 will then move axially within the assembly column 6. This will cause the T-shaped frame 103 to clamp the rebar frame between the locking groove 104 and the angle iron frame 1 via the frame rod 102.

[0027] The angle iron frame 1 is distributed vertically, the water-stop steel plate 3 is located between the angle iron frames 1, and the strip hole 4 is connected to the corresponding connecting hole 5 by the same bolt 12.

[0028] The lower angle iron frame 1 is fixedly connected to the bottom steel reinforcement frame. The water-stop steel plate 3 is placed on top of the angle iron frame 1. Another angle iron frame 1 is then placed on the water-stop steel plate 3 so that the strip hole 4 and the connecting hole 5 are aligned. Then, the lower angle iron frame 1, the water-stop steel plate 3 and the upper angle iron frame 1 are fixedly connected by bolts 12.

[0029] Working principle:

[0030] Step 1: Place the angle iron frame 1 on top of the bottom steel reinforcement frame. Move the assembly column 6 to allow the short rod 8 to move within the strip hole 4 until the steel reinforcement frame is positioned between the T-shaped frame piece 103 and the angle iron frame 1, and align any locking groove 104 with the steel reinforcement frame. Use an electric wrench to rotate the bolt head screw 9. Since the internal threaded cylinder 101 is threadedly connected to the bolt head screw 9, it will then move axially within the assembly column 6. This will cause the T-shaped frame piece 103 to clamp the steel reinforcement frame between the locking groove 104 and the lower angle iron frame 1 via the frame rod 102, thus fixing the lower angle iron frame 1 to the bottom steel reinforcement frame.

[0031] Step 2: The lower angle iron frame 1 is fixedly connected to the bottom steel bar frame. The water-stop steel plate 3 is placed on top of the angle iron frame 1. Then another angle iron frame 1 is placed on the water-stop steel plate 3 so that the strip hole 4 and the connecting hole 5 are aligned. Then the lower angle iron frame 1, the water-stop steel plate 3 and the upper angle iron frame 1 are fixedly connected by bolts 12.

[0032] Step 3: Lay the top layer steel reinforcement frame above the upper angle iron frame 1, so that the steel reinforcement is located between the locking groove 104 and the upper angle iron frame 1, and the locking groove 104 is aligned with the steel reinforcement frame. This is the same as the fixing operation method of the lower angle iron frame 1 and the bottom steel reinforcement frame in the first step. This will fix the upper and lower angle iron frames 1 and the top steel reinforcement frame, thus completing the positioning of the dense wire mesh 2.
