Description

Technical Field

[0001] This utility model relates to the field of sealing technology in building construction, and in particular to a sealing device that does not require formwork. Background Technology

[0002] A double-T slab is a reinforced concrete load-bearing component that combines slab and beam elements. It consists of a wide panel and two narrow, tall ribs. The panel serves as both a transverse load-bearing structure and the compression zone for the longitudinal load-bearing ribs.

[0003] Double-T panels are mostly used for prefabricated roof panels in factories or workshops. After being manufactured in the factory, they are transported to the site, hoisted onto the roof truss, and the joints between the panels are sealed before the roof composite layer is poured. Due to construction errors, the joints between the panels can be 20-50mm. Currently, if grouting is used to seal the panels, scaffolding needs to be erected for both installation and removal. The process of sealing the joints between the panels is complicated, has a long construction period, and is time-consuming and labor-intensive. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a formwork-free sealing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] A formwork-free sealing device includes a reinforcing spring, a pull tab, and a sealing base plate. Multiple vertically arranged pull tabs are fixedly connected at equal intervals in the upper middle part of the sealing base plate. A reinforcing spring is fixedly connected to the upper end of each pull tab. The reinforcing spring, pull tab, and sealing base plate form an "I" shaped structure.

[0007] The reinforcing spring is an elastic arc plate;

[0008] The sealing base plate includes a connecting strip, sealing side plates, and a pull ring. The connecting strip is fixedly connected to the lower part of the pull plate, and sealing side plates are connected to both sides of the connecting strip. A pull ring is fixedly connected to the lower end of the connecting strip.

[0009] As a further improvement of this utility model, the pull tab has a hollow mesh structure, and the reinforcing spring is a flexible metal arc plate.

[0010] As a further improvement of this utility model, the reinforcing spring sheet has a hollowed-out mesh structure.

[0011] As a further improvement of this utility model, a tear slit is provided at the connection between the sealing side plate and the connecting strip, which facilitates the removal of the sealing side plate by pulling the connecting strip.

[0012] As a further improvement of this utility model, the connecting strip, the sealing side plate, and the pull ring are made of polyethylene.

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

[0014] This utility model has a simple structure and low manufacturing cost. When using it, before hoisting the double T-panel on the roof, the burrs on the edges of the panels are ground off, and the device is directly fitted onto the edge of the panel. After the second panel is hoisted into place, the other half of the device is fixed to the edge of the second panel, and the bottom of the joint between the two panels is sealed tightly. Then, concrete is poured. This eliminates the need for wooden formwork and hoisting. After the concrete reaches the design strength, a long hook is inserted into the removal ring on the indoor ground, and the sealing bottom plate is removed by force. No scaffolding is required, saving time and labor. Attached Figure Description

[0020] Please refer to Figs. 1-2 A formwork-free sealing device includes a reinforcing spring 1, a pull tab 2, and a sealing base plate 3. Multiple vertically arranged pull tabs 2 are fixedly connected at equal intervals in the upper middle part of the sealing base plate 3. A reinforcing spring 1 is fixedly connected to the upper end of each pull tab 2. The reinforcing spring 1, pull tab 2, and sealing base plate 3 form an "I" shaped structure.

[0021] Reinforcing spring 1 is an elastic arc plate;

[0022] The sealing base plate 3 includes a connecting strip 31, a sealing side plate 32, and a pull ring 33. The connecting strip 31 is fixedly connected to the lower part of the pull plate 2. The sealing side plates 32 are connected to both sides of the connecting strip 31. The pull ring 33 is fixedly connected to the lower end of the connecting strip 31.

[0023] The pull tab 2 has a hollow mesh structure, the reinforcing spring tab 1 has a hollow mesh structure, and the reinforcing spring tab 1 is a flexible metal arc plate.

[0024] A tear slit 34 is provided at the connection between the sealing side plate 32 and the connecting strip 31. The connecting strip 31, the sealing side plate 32 and the pull ring 33 are made of polyethylene material, which makes it easy to pull the connecting strip 31 to remove the sealing side plate 32.

[0025] Before hoisting the double T-panel on the roof, grind off any burrs on the edges of the panels and directly slip the device onto the edge of the panel. After the second panel is hoisted into place, fix the other half of the device onto the edge of the second panel, press the two ends of the reinforcing spring 1 to make the reinforcing spring 1 form an arched structure, and pull upward to seal the bottom plate 3, thereby sealing the bottom of the joint between the two panels. Then pour concrete and vibrate it. After the concrete has initially set, use the long rod with hooks to pull the pull ring 33 to pull and tear the connecting strip 31 and the sealing side plate 32 apart. Then the connecting strip 31 and the sealing side plate 32 fall off, thus achieving disassembly.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
