Embodiment 1

[0033] Such as Figure 1 to Figure 4 As shown, the reusable pre-embedded ring includes a U-shaped hoop 3, a pressing plate 5 and a nut 6, the pressing plate 5 is also provided with two through holes, and the U-shaped hoop 3 includes an intermediate section 31 and a The end sections 32 on both sides of the middle section 31, two through holes are used to insert different end sections 32 respectively, and at least one nut 6 is screwed on the two free ends of the U-shaped hoop 3, and the nuts The cap 6 and the middle section 31 are respectively located on different sides of the pressure plate 5, and also includes two tubular sleeves 2, which are pre-embedded in the concrete 1 when the concrete 1 is poured, and the length of each sleeve 2 is equal to The thickness of the concrete 1 in the respective pre-embedded positions is consistent, and when installed, the upper ends of the casings 2 are flush with the upper surface of the concrete 1, and the lower ends of the casings 2 are fl...

Embodiment 2

[0039] Such as Figure 1 to Figure 4 As shown, this embodiment is further defined on the basis of embodiment 1: in order to make the casing 2 embedded in the concrete 1 have a reliable bonding strength with the concrete 1 during the use of the building, and at the same time make the Next, the sleeves 2 can transmit force very well, avoiding the concrete 1 from being destroyed due to a large local stress concentration, and the outer wall surface of each sleeve 2 is provided with a plurality of protrusions, and the protrusions The part protrudes outward relative to the outer wall surface of the casing 2. Above protruding part can adopt the steel bar, steel pipe etc. that are welded on the outer wall surface of sleeve pipe 2.

[0040] In some special cases, if it is necessary to add functional layers such as wear-resistant layer, decorative layer, and waterproof layer on the surface or bottom of concrete 1, in order to facilitate the firmness of the connection between the functi...

Embodiment 3

[0042] This embodiment further limits this case on the basis of the technical solution provided in embodiment 1, as Figure 1 to Figure 4 As shown, a locking device 8 is fixed on each end section 32, and the locking device 8 includes a splint 81, a connecting bolt 82 and a jacking bolt 83, and the connecting bolt 82 is used to lock the splint 81 on the end. On the section 32, the jacking bolt 83 is threadedly connected to the splint 81, and the end of the threaded section of the jacking bolt 83 faces the cantilever beam 4. During the rotation of the jacking bolt 83, the The end of the threaded section can move toward one side of the cantilever beam 4 and contact with the cantilever beam 4 .

[0043] Since the cantilever beam 4 is to be fixed between the openings of the U-shaped hoop 3, it must be set that the width of the cantilever beam 4 is smaller than the width of the opening, and when the cantilever beam 4 is in use, the When a force other than tensile or compressive str...

Abstract

The invention discloses a reusable pre-embedded ring comprises a U-shaped ring hoop, a pressing plate and nuts. Two through holes are further formed in the pressing plate. The U-shaped ring hoop comprises an intermediate section and end sections on the two sides of the intermediate section. The one or more nuts are connected at the two free ends of the U-shaped ring hoop in a threaded mode. The reusable pre-embedded ring further comprises two tubular sleeves. By means of the structure design of the pre-embedded ring, the U-shaped ring hoop of the pre-embedded ring is convenient to dismantle after using, so that the U-shaped ring hoop can be reused, meanwhile, concrete is not damaged in the dismantling process, and accordingly guaranteeing of the performance of the concrete is facilitated.

Description

technical field [0001] The invention relates to the technical field of scaffolding construction devices for construction engineering, in particular to a reusable pre-embedded ring. Background technique [0002] Scaffolding refers to various supports erected for operators to solve vertical and horizontal transportation or operations at the construction site, such as the exterior walls and interior decoration of high-rise buildings where direct construction cannot be performed. In the prior art, in addition to the traditional method of erecting scaffolds directly from the ground, a new scaffolding construction method has been developed in recent years: using the floor slab that has been poured on the lower floor as the foundation for scaffolding. The above new scaffold construction method needs to embed embedded parts in the floor. The above embedded parts are used to fix the cantilever beams. The above cantilever beams protruding from the building are the bottom support platf...
