Hanging nail structure and thin-wall wallboard

Abstract

The utility model provides a hanging nail structure and a thin-wall wallboard, and the hanging nail structure is arranged in the thin-wall wallboard and comprises an embedded hanging nail and a connecting unit, the embedded hanging nail is provided with a nail body and a connecting ring arranged at the bottom of the nail body. The connecting units comprise connecting steel bars penetrating through the connecting rings. The connecting steel bar penetrates through the connecting ring at the bottom of the nail body to form a penetrating type hanging bar, so that damage to wall concrete when the pre-embedded hanging nail is pulled is reduced, and the connecting strength of the pre-embedded hanging nail and the wallboard body is improved; meanwhile, the connecting steel bars also play a role of reinforcing ribs, so that the rigidity of the thin-wall wallboard is improved, and the risk that the thin-wall wallboard is bent and damaged when being lifted and overturned is reduced. The problems that due to the fact that the contact force between an embedded hanging nail of an existing prefabricated thin-wall type wallboard and wallboard concrete is small, the embedded hanging nail is prone to disengaging from a wallboard body due to the fact that the wall thickness of the wallboard is small in the hoisting process, and the embedded hanging nail is stressed are solved.

Description

Technical Field

[0001] The utility model relates to the technical field of building structures, and more specifically, to a hanging nail structure and a thin-walled wall panel. Background Art

[0002] In the domestic prefabricated building industry, round-headed hanging nails are often used for hoisting during the demoulding, transportation and installation processes of prefabricated components. During the production of prefabricated components, the round-headed hanging nails are embedded. The embedding of such round-headed hanging nails requires the use of hemispherical "wave glue" as a supporting component. During the production process, the hemispherical "wave glue" is fixed on the side mold of the prefabricated component. After the prefabricated component is poured and completed, the "wave glue" is removed, and a hemispherical space is formed around the hanging nail. Generally, the diameter of the hemisphere is 75 mm. The hoisting of prefabricated components requires the use of a "duckbill buckle" hoisting tool as a supporting component.

[0003] The production of prefabricated components such as prefabricated wall panels mainly adopts flat pouring. Before the prefabricated components are transported, they must be demoulded first, then flipped and hoisted, and directly hoisted from the mold table to adjust the prefabricated components from a lying state to an upright state. Since modular buildings integrate building forms such as structure, decoration, mechanical and electrical, and plumbing and heating, they have the characteristic of large self-weight. At present, most of the concrete MIC forms are MIC (formwork) plus cast-in-place shear wall structure forms. The hanging points are designed as embedded nuts plus hoisting tools or lifting rings / hooks plus hoisting tools. During the hoisting process, a stress concentration area is formed at the top of the hanging nail, and if the wall panel itself is a non-load-bearing wall, safety accidents are likely to occur.

[0004] The utility model patent with the publication number CN214117228U discloses a prefabricated wall panel with hanging nails. The prefabricated wall panel includes a wall panel body; the wall panel body has a first surface and a second surface that are oppositely arranged, a first end face and a second end face that are oppositely arranged, and a first side face and a second side face that are oppositely arranged; at least two through grooves are opened on the first end face and / or the second end face, and the through grooves are U-shaped in any cross-section parallel to the first surface or the second surface; an embedded hanging nail is provided in a direction perpendicular to the first end face and the second end face, one end of the embedded hanging nail is embedded in the wall panel body, and the other end extends into the through groove; the extended end of the embedded hanging nail does not exceed the first end face and / or the second end face.

[0005] However, in the above-mentioned prefabricated wall panel, since one end of the embedded hanging nail is embedded in the wall panel body and the other end extends into the through groove, the contact force between the embedded hanging nail and the wall panel concrete is small. When hoisting, due to the small wall thickness of the wall panel, especially for thin-walled wall panels with a wall thickness not exceeding 50 mm, the embedded hanging nail is stressed and easily disengages from the wall panel body. Summary of the Utility Model

[0006] Based on this, in order to solve the problem that the embedded lifting nails of the above precast wall panels are easy to break away from the wall panel body due to the small contact force with the wall panel concrete and the small wall thickness of the wall panel and the force on the embedded lifting nails during lifting, the present utility model provides a lifting nail structure and a thin-walled wall panel, and its specific technical solutions are as follows:

[0007] On the one hand, a lifting nail structure is provided in a thin-walled wall panel, including an embedded lifting nail and a connecting unit; the embedded lifting nail is provided with a nail body and a connecting ring arranged at the bottom of the nail body; the connecting unit includes a connecting steel bar passing through the connecting ring.

[0008] The above-mentioned lifting nail structure forms a through-type lifting bar by passing the connecting steel bar through the connecting ring at the bottom of the nail body, so as to reduce the damage to the wall concrete when the embedded lifting nail is in tension, thereby improving the connection strength between the embedded lifting nail and the wall panel body; at the same time, the connecting steel bar also acts as a reinforcing bar, improving the stiffness of the thin-walled wall panel and reducing the risk of bending damage when the thin-walled wall panel is lifted and flipped.

[0009] Further, the connecting unit further includes a horizontal steel bar arranged at the joint of the connecting ring and the nail body.

[0010] Further, the connecting unit further includes a reinforcing steel bar pressing the horizontal steel bar towards the connecting ring.

[0011] On the other hand, a thin-walled wall panel includes a wall panel body and a lifting nail structure; the lifting nail structure is arranged on the wall panel body.

[0012] Further, an avoidance groove is provided on the upper end surface of the wall panel body; the top of the nail body is exposed in the avoidance groove, and the protruding part of the nail body does not exceed the upper end surface of the wall panel body.

[0013] Further, the avoidance groove is a spherical groove.

[0014] Further, the connecting steel bar is a bent steel bar in a U-shaped structure, and the connecting ring is sleeved on the top of the bent steel bar.

[0015] Further, the bottom of the bent steel bar is exposed below the wall panel body.

[0016] Further, it further includes a connecting beam body arranged at the bottom of the wall panel body; a stirrup frame is arranged in the connecting beam body; the bottom of the bent steel bar is connected to the stirrup frame.

[0017] Further, the thickness of the wall panel body does not exceed 50 mm. Description of the Drawings
