Description

Technical Field

[0001] The invention belongs to the technical field of construction, and in particular relates to a steel casing rigid-connected wall panel embedded part device and a manufacturing method thereof. Background Art

[0002] As the external protective structure of the steel structure, the prefabricated external wall panels should not only have good thermal insulation functions, but also be "lightweight and high-strength", that is, on the basis of meeting the strength requirements of the specifications, they are relatively light. Prefabricated external wall panels are generally composite wall panels (wall panels made by mixing cement, slag powder, desulfurized gypsum, fly ash and other cementitious materials with sand, polystyrene particles, etc.). Considering that this composite wall panel has the characteristics of lighter weight and lower strength compared with general concrete wall panels, the embedded parts used should also be different from the embedded parts of traditional concrete wall panels. Considering the equipment operation requirements for factory-based mass production of prefabricated external wall panels and the need to stack wall panels during transportation and stacking, wall panels with flat surfaces on both sides will undoubtedly help improve the production efficiency of wall panel preparation, and save space and ensure safety during the transportation and stacking of wall panels.

[0003] In the prior art, prefabricated external wall panels mostly use traditional π-type embedded parts or double steel plate embedded threaded sleeve embedded parts. Compared with traditional π-type embedded parts, the present invention has the advantage of better bonding integrity with prefabricated wall panels; and the connection between traditional π-type embedded wall panels and steel frames can only be achieved by direct welding or welding of connectors and then bolting, which increases the amount and difficulty of on-site construction work. Compared with double steel plate embedded threaded sleeve embedded parts, the use of bolt pre-embedded methods effectively solves the problem of materials blocking bolt holes during the casting of wall panels, and can effectively avoid the problem of bolt loosening after the wall panels are installed. In addition, the exposed bolts of traditional wall panel embedded parts will increase the difficulty and transportation cost of casting and maintenance of wall panels to a certain extent. Based on this, the present invention came into being Summary of the invention

[0004] The purpose of the present invention is to provide an embedded part for an assembled steel structure prefabricated external wall panel with a simple structure and convenient construction, so as to solve the problems of the existing embedded parts for external wall panels having a single form and inconvenient construction.

[0005] The specific technical scheme of the present invention is: a steel casing rigid connection type wall panel embedded device, the embedded device is composed of eight parts: surface steel plate, bottom steel plate, mounting bolt, round steel anchor pipe, round steel stiffening pipe, steel circular anchor plate, mounting bolt gasket and L-shaped extension screw. A circular hole is opened in the center of the surface steel plate, the mounting bolt is a right-handed thread, a concave circular hole is opened at the center of the screw end, and a left-handed thread is provided on the inner side of the hole; a left-handed thread is provided on the outer side of the long side end of the L-shaped extension screw; one end of the round steel stiffening pipe is placed in the center of the outer periphery of the circular hole on the inner surface of the surface steel plate and welded, and the other end is aligned and welded with one side of the steel circular anchor plate in the center; one end of the round steel anchor pipe is aligned and welded with the bottom steel plate in the center, and the other end is aligned and welded with the other side of the steel circular anchor plate in the center; the mounting bolt is built into the round steel anchor pipe, passes through the round steel stiffening pipe, and extends into the circular hole of the surface steel plate, forming an embedded part for the external wall panel.

[0006] Furthermore, the L-shaped extension screw can be screwed into the concave circular hole at the end of the mounting bolt, so as to pull out and lock the mounting bolt, thereby preventing the mounting bolt from idling when the nut is tightened.

[0007] Furthermore, the outer surfaces of the surface steel plate and the bottom steel plate are flush with the two sides of the wall panel respectively, the surface steel plate and the bottom steel plate are parallel to each other, the round steel anchor pipe is centered and vertically welded with the bottom steel plate, and the round steel stiffening pipe is centered and vertically welded with the surface steel plate.

[0008] Furthermore, the round steel anchor pipe, round steel stiffening pipe and steel circular anchor plate are concentric circles, and the round steel anchor pipe and round steel stiffening pipe are respectively aligned in the center and welded on both sides of the steel circular anchor plate.

[0009] Furthermore, the manufacturing method of the steel casing rigid-connected wall panel embedded part device comprises the following steps:

[0010] First, one end of the round steel stiffening tube is centered on the outer circumference of the circular hole on the inner surface of the surface steel plate and welded, and the other end is centered and aligned with one side of the steel circular anchor plate and welded; secondly, one end of the round steel anchor tube is centered and aligned with the bottom steel plate and welded; finally, the mounting bolt is built into the round steel anchor tube, passed through the round steel stiffening tube, and extended into the circular hole of the surface steel plate, and the other end of the round steel anchor tube is centered and aligned with the other side of the steel circular anchor plate and welded to complete the production of the embedded parts.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1) The embedded parts device for prefabricated external wall panels of the assembled steel structure system of the present invention is formed into a stable whole by placing the round steel anchor pipe and the round steel stiffening pipe in the middle vertically and at intervals between the bottom steel plate, the steel circular anchor plate and the surface steel plate arranged in parallel, and welding them with fillet welds. The embedded parts have good bonding and anchoring properties with the prefabricated wall panel concrete through the arrangement of the bottom plate, the round steel anchor pipe and the steel circular anchor plate.

[0013] 2) The embedded parts device for prefabricated external wall panels of the assembled steel structure system of the present invention is self-contained and can realize standardized production; the height of the embedded parts is consistent with the thickness of the wall panels, the surface steel plate and the bottom steel plate of the embedded parts are flush with the inner and outer surfaces of the prefabricated wall panels respectively, and the embedded parts mounting bolts are built into the embedded parts, which avoids the bolts being exposed on the surface of the prefabricated wall panels, and is convenient for casting, transportation and stacking of the prefabricated wall panels.

[0014] 3) The embedded parts device for the prefabricated external wall panels of the assembled steel structure system of the present invention has mounting bolts arranged inside the embedded parts. When the wall panels are installed, the L-shaped extension screw can directly take out the bolts and bolt them to the main steel structure frame. The embedded parts mounting bolts can be bolted to the U-shaped lifting rings of the special lifting device and directly used for the lifting of the wall panels, thereby effectively solving the problem of the need to bury the lifting rings for the lifting of the wall panels.
