[0002] With the development of social economy, high-rise buildings have gradually become the mainstream of housing construction. The number of horizontal floor openings reserved for construction measurement, pipeline pre-embedding, construction material delivery and material transportation has also gradually increased. People stepping on the openings and falling or objects falling from the openings are prone to accidents that threaten life safety. Therefore, the safety protection and blocking of horizontal openings in the project are extremely important. At present, the safety protection devices for horizontal openings in the project are mostly directly covered with plates, and the blocking is mostly done by the method of supporting the template at the bottom and casting concrete on the top. This safety protection device and blocking device have the following disadvantages in installation, use and disassembly:

[0003] 1. The horizontal opening is directly covered with a plate, which is easy to move and poses a safety hazard;

[0004] 2. When plugging, the installation and support of the lower formwork is complicated and difficult, and it is easy to cause leakage due to poor plugging due to unstable support;

[0005] 3. After the plugging is completed, the disassembly process of the lower formwork is rather cumbersome. The components of the support system are too large and too heavy, and it is impossible for one person to complete the disassembly work, which increases labor costs. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a dual-purpose device for horizontal opening safety protection and hanging formwork construction blocking, in view of the shortcomings of existing horizontal opening safety protection devices and blocking devices. The device can not only improve the safety of the horizontal opening safety protection device and the convenience of installation and disassembly of the blocking device, but also improve the one-time forming quality of the secondary pouring of concrete at the opening, thereby improving the stability, safety and durability of the overall structure, improving construction efficiency and saving labor costs.

[0007] The utility model solves the technical problem by adopting a technical solution: a dual-purpose device for horizontal opening safety protection and hanging formwork construction plugging, comprising a plugging template, square steel, a screw rod, a first nut, a gasket and a steel wire rope;

[0008] When used as a safety protection device for horizontal openings, the blocking template is located at the upper part of the horizontal opening of the floor slab, and square steel is provided at the upper part of the blocking template and the lower part of the horizontal opening of the floor slab respectively. The screw rod passes through the upper square steel, the blocking template and the lower square steel in sequence, and is reinforced by the first nut and the gasket at both ends, and one end of the steel wire rope is fixedly connected to the upper end of the screw rod;

[0009] When used as a plugging device for hanging formwork construction, the plugging template is located at the lower part of the horizontal opening of the floor slab, and square steels are respectively provided at the lower part of the plugging template and the upper part of the horizontal opening of the floor slab. The screw rod passes through the upper square steel, the plugging template and the lower square steel in sequence, and is reinforced by the first nut and gasket at both ends. One end of the steel wire rope is fixedly connected to the upper end of the screw rod, wherein a gasket is provided between the upper square steel and the floor slab, a second nut is provided between the plugging template and the screw rod, and a sleeve is provided outside the second nut.

[0010] Furthermore, the blocking template is provided with a circular hole for installing a screw.

[0011] Furthermore, the square steel is provided with a round hole for installing a screw rod.

[0012] Furthermore, the sleeve has a structure that is narrow at the bottom and wide at the top.

[0013] Furthermore, the top end of the sleeve is higher than the upper end surface of the floor slab.

[0014] Furthermore, the bottom end of the sleeve is tightly sleeved on the second nut.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the plugging template is closely attached to the floor slab by square steel, screw rod, first nut and gasket, so as to achieve the two effects of safety protection and preventing plugging leakage, improve the safety of the horizontal hole safety protection device, and improve the one-time forming quality of the secondary pouring of concrete at the hole. Since the components of the device are simple and easy to install and disassemble, only one worker is required to complete it, and when pouring concrete to plug the hole, the device can be completely taken out, which improves the stability, safety and durability of the overall structure, improves the construction efficiency and saves labor costs.
