Description

Technical Field

[0001] This utility model relates to the field of construction formwork technology, specifically a detachable lowering formwork device. Background Technology

[0002] To prevent leaks in the structural slabs of bathrooms and kitchens, a 50mm drop in the slab height is typically designed. During floor slab construction, this area requires suspended formwork. Currently, most construction companies weld square steel for the suspended formwork based on the drop slab dimensions, or customize it using square timber. Both methods have low reuse rates during the suspended formwork process. Furthermore, the concrete strength is generally not very high when the suspended formwork is removed, requiring considerable force and the use of pry bars to dismantle it. This often results in extensive damage to the concrete edges and corners. In addition, due to the current decline in the construction market and the need to reduce costs, some bathroom and kitchen designs do not include leveling measures. This damage to the edges and corners severely affects the subsequent application of waterproof coatings in the bathrooms and results in a poor appearance of the concrete.

[0003] Therefore, it is necessary to develop a detachable lowering plate hoisting device. Utility Model Content

[0004] The purpose of this invention is to provide a detachable lowering plate hoisting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable lowering plate hoisting device, comprising a square steel, a screw rod installed on the upper part of one outer wall of the square steel, and a gasket installed on one side of the outer wall of the screw rod;

[0006] An angle steel is installed on one side of the top of the square steel.

[0007] Preferably, the screw and the square steel are welded together, and the screw is at a 45-degree angle.

[0008] Preferably, a mounting hole A is provided at the center of the surface of the gasket, and the interior of the mounting hole A is slidably connected to the outer wall of the screw.

[0009] Preferably, a mounting hole B is provided at the center of the surface of the angle steel, and the interior of the mounting hole B is slidably connected to the outer wall of the screw.

[0010] Preferably, a nut is installed on the other side of the outer wall of the screw, and the inner wall of the nut is threadedly connected to the outer wall of the screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By welding the screw rod at a 45-degree angle to the corner of the square steel, and sliding the mounting hole B on the angle steel to the outer wall of the screw rod, then inserting a washer and tightening the nut, the angle steel is smoothly and firmly connected to the square steel, allowing for concrete formwork installation. After the concrete reaches the demolding strength, the nut, washer, and angle steel are removed in sequence, enabling easy and quick disassembly and assembly of the suspended formwork. Combined with the suspended formwork support and elevation control during concrete pouring, the appearance of the concrete in the lowered slab area can be greatly improved, effectively enhancing the construction quality and efficiency in the lowered slab area.

[0018] 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.

[0019] This utility model provides the following technical solution: a detachable lowering plate hoisting formwork device, please refer to... Figures 1-4 The structure includes a square steel 1, a screw 2 installed on the upper part of one outer wall of the square steel 1, the screw 2 and the square steel 1 are welded together, the screw 2 is at a 45-degree angle, a gasket 3 is installed on one side of the outer wall of the screw 2, and a mounting hole A4 is opened at the center of the surface of the gasket 3. The interior of the mounting hole A4 is slidably connected to the outer wall of the screw 2, and the gasket 3 plays the role of vertical force bearing.

[0020] An angle steel 5 is installed on one side of the top of square steel 1. An installation hole B6 is opened at the center of the surface of angle steel 5.
