Description

Technical Field

[0001] This utility model belongs to the field of anti-leakage technology, specifically a leveling and anti-leakage device for composite plates. Background Technology

[0002] With the development of modern industrial technology, prefabricated buildings are now widely used in the construction industry. Houses can be manufactured in batches, much like machine production. Prefabricated building components are simply transported to the construction site and assembled. The main types of prefabricated components include: composite slabs, prefabricated stairs, prefabricated beams, and prefabricated columns.

[0003] Currently, in existing technologies, composite slabs with leveling and leak-proof devices are mainly used in the following types of components: composite slabs, precast stairs, precast beams, and precast columns.

[0004] Existing composite slab leveling and leak-proof devices require disassembling horizontal components into several pieces for production and on-site installation when the span of structural beams and slabs is large. The construction of the joints between these pieces directly affects the final quality of the prefabricated building. The joints between composite slabs are typically constructed with 300mm wide strips. Due to factors such as composite slab installation and formwork splicing, frequent grout leakage from the strips is a major quality problem plaguing prefabricated buildings. Therefore, this paper proposes a composite slab leveling and leak-proof device to address this issue. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a leveling and leak-proof device for composite plates and strips.

[0007] Preferably, an iron hook is fixedly connected to one side of the composite plate body; a telescopic plate is slidably connected to the inner surface wall of the composite plate body.

[0008] Preferably, a damping rod is fixedly connected to the inner surface wall of the composite plate body; the damping rod is slidably connected to the inner surface wall of the telescopic plate.

[0009] Preferably, the composite plate body is fixedly connected to a return spring via a telescopic plate; an adjusting screw is threadedly connected to the inner surface wall of the telescopic plate.

[0011] Preferably, a limiting rod is fixedly connected to the top of the pressing plate; the limiting rod is slidably connected to the inner surface wall of the telescopic plate.

[0012] Preferably, the width of the strip template is 400mm; the angle iron is made of stainless steel.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a leveling and leak-proof device for composite strips. By setting angle irons and screws, the composite plates at both ends of the strip are firmly fixed to the strip template, so that the composite plates are closely attached to the strip template. This can effectively block the lateral impact of vibrating concrete material, which can cause displacement of the strip template and composite plates, avoid the misalignment of the composite plates at both ends, ensure the flatness of the strip after the concrete structure is formed, and save the labor and cost of cleaning the strip leakage after the structure is formed.

[0015] This utility model provides a leveling and leak-proof device for composite panels. By setting a telescopic plate, the device can change the abutment length of the composite panel body. At the same time, the setting of the pressing plate can change the abutment height, thereby increasing the applicability and practicality of the device. Attached Figure Description

There is a first reinforcing screw 9; the outer wall of the first reinforcing screw 9 is threaded with a first bolt 10; during operation, after the hoisting and leveling are completed, a 400mm long angle iron 2 is left on the adjacent composite plate body 3 on both sides of the plate strip. Then, on the angle iron 2 and the plate strip template 1, a first screw hole 17 and a second screw hole 18 are left along the edge of the composite plate body 3 at both ends of the plate strip. The connected first reinforcing screw 9 and second reinforcing screw 12 are passed through the first screw hole 17 and the second screw hole 18 on the angle iron 2 and the plate strip template 1, and locked with the first bolt 10 and the second bolt 13. The composite plate body 3 at both ends of the strip is firmly clamped to the strip template 1 by the locked angle iron 2. When the concrete is poured on the plate surface, the first reinforcing screw 9 and the angle iron 2 are embedded in the structural concrete. When the strip is demolded, the first bolt 10 locked on the strip template 1 is loosened, the rubber head 11 is pried and the second reinforcing screw 12 is rotated to remove it. The opening of the rubber head 11 at the bottom of the strip is filled and leveled with mortar.

[0027] Furthermore, such as Figure 2 and Figure 4As shown, an iron hook 5 is fixedly connected to one side of the composite plate body 3; a telescopic plate 4 is slidably connected to the inner surface of the composite plate body 3; a damping rod 14 is fixedly connected to the inner surface of the composite plate body 3; the damping rod 14 is slidably connected to the inner surface of the telescopic plate 4; a return spring 15 is fixedly connected to the composite plate body 3 through the telescopic plate 4; an adjusting screw 7 is threadedly connected to the inner surface of the telescopic plate 4; a knob 6 is fixedly connected to the top of the adjusting screw 7; a pressing plate 16 is rotatably connected to the bottom of the adjusting screw 7; a limit rod 8 is fixedly connected to the top of the pressing plate 16; the limit rod 8 is slidably connected to the inner surface of the telescopic plate 4; the width of the plate strip template 1 is 400mm; the angle iron 2 is made of stainless steel. During operation, the telescopic plate 4 slides within the composite plate body 3, and the damping rod 14 and the return spring 15 serve as limiting sliding structures to change the pressing width. At the same time, by rotating the knob 6, the adjusting screw 7 can be threaded down, and the pressing plate 16 can move downward under the limit of the limiting rod 8, thereby changing the contact height.

[0028] Working principle: After the hoisting and leveling are completed, 400mm long angle irons 2 are left on the adjacent composite plate body 3 on both sides of the plate strip. Then, on the angle irons 2 and the plate strip template 1, the first screw hole 17 and the second screw hole 18 are left along the edge of the composite plate body 3 at both ends of the plate strip. The connected first reinforcing screw 9 and the second reinforcing screw 12 are passed through the first screw hole 17 and the second screw hole 18 on the angle irons 2 and the plate strip template 1, and locked with the first bolt 10 and the second bolt 13. The composite plate body 3 at both ends of the strip is firmly clamped to the strip template 1 by the locked angle iron 2.

When the strip is demolded, the first bolt 10 locked on the strip template 1 is loosened, the rubber head 11 is pried and the second reinforcing screw 12 is rotated to remove it. The opening of the rubber head 11 at the bottom of the strip is filled and leveled with putty. By using the telescopic plate 4 to slide in the composite plate body 3, and then using the damping rod 14 and the return spring 15 as the limiting sliding structure, the pressing width can be changed. At the same time, by rotating the knob 6, the adjusting screw 7 can be threaded down, and the pressing plate 16 can be moved downward under the limit of the limiting rod 8, thereby changing the abutment height.
