Description

Technical Field

[0001] The invention belongs to the field of underground building construction, and in particular relates to a hollow concrete partition wall of an underground shopping mall. Background Art

[0002] At present, in some big cities, due to the large population and shortage of resources in all aspects, especially the usable area of ​​buildings, some large shopping malls choose to open in shopping plazas or basements of large buildings. As we all know, the basements of large buildings are empty. Opening a large shopping mall in an empty basement requires structural transformation of its building space, including building partition walls to separate the space. The partition walls required for underground shopping malls need to meet the characteristics of light weight, high temperature insulation, sound insulation, warmth preservation, corrosion resistance, fire resistance and combustion resistance, electrical insulation and environmental protection.

[0003] However, since partition walls are not load-bearing components, there will be material waste during production. In addition, integrated prefabricated partition walls will be difficult to transport, difficult to install, and have insufficient insulation and fire protection. Summary of the invention

[0004] In order to solve the above-mentioned technical problems, the present invention provides a new type of hollow concrete partition wall for underground shopping malls, mainly for developing a hollow concrete partition wall and connection method for underground shopping malls with good integrity, simple structure, convenient connection, safety and reliability, which can effectively solve the problems of construction difficulties, complex installation, cumbersome construction, long construction period, loose connection, low stability, etc., and can also reasonably arrange the hollow parts with insulation, sound insulation and other materials.

[0005] The technical solution adopted by the present invention is as follows:

[0006] The hollow concrete partition wall of the underground shopping mall includes a single-leaf concrete wall, a concrete wall connector, a concrete cuboid short column, a connecting thin steel plate, and a high-strength bolt; the single-leaf concrete wall is provided with a T-shaped cylindrical rib, a cylindrical protruding empty groove, an L-shaped rib, and a reserved steel plate groove; the L-shaped rib is arranged in the middle of the single-leaf concrete wall, and the T-shaped cylindrical rib and the cylindrical protruding empty groove are symmetrically distributed on both sides of the L-shaped rib; A reserved steel plate groove is arranged under the single-leaf concrete wall, and a connecting thin steel plate is inserted into the reserved steel plate groove. The length of the connecting thin steel plate is less than the length of the single-leaf concrete wall. A reserved bolt hole is arranged on the connecting thin steel plate. The two connecting thin steel plates inserted into the reserved steel plate groove are connected by high-strength bolts, thereby connecting the upper and lower single-leaf concrete walls; when the two single-leaf concrete walls are opposite to each other, the flanges of the two L-shaped ribs overlap each other, and the T-shaped cylindrical rib on one side of the single-leaf concrete wall is inserted into the cylindrical protruding hollow groove on the other side of the single-leaf concrete wall, and a rectangular groove is formed between the two L-shaped ribs. A concrete rectangular short column is inserted into the groove to fix the two opposite single-leaf concrete walls to form a partition wall; one end of the partition wall is connected to the concrete wall connector.

[0007] Furthermore, the L-shaped rib is higher than the cylindrical protruding slot by the thickness of the L-shaped rib flange.

[0008] Furthermore, a rectangular rib is prefabricated on the concrete wall connector, and a plurality of reserved bolt holes are arranged on the rectangular rib; the reserved bolt holes on the rectangular rib correspond to the reserved bolt holes at one end of the single-leaf concrete wall, and the rectangular rib and the single-leaf concrete wall are connected by high-strength bolts.

[0009] Furthermore, two reserved bolt holes are symmetrically arranged on the connecting thin steel plate to facilitate the connection of the upper and lower single-leaf concrete walls.

[0010] Furthermore, the rectangular ribs on the wall connectors are arranged according to the wall positions, which include side walls, corner walls, corner walls and four walls. The types of rectangular ribs corresponding to the wall connectors are straight, L-shaped, T-shaped and cross-shaped, and the numbers of rectangular ribs corresponding to the wall connectors are one, two, three and four.

[0011] Beneficial effects of the present invention: the hollow concrete partition wall of an underground shopping mall of the present invention has a simple structure, convenient connection, good integrity, safety and reliability, convenient construction, fast construction speed, convenient transportation, light material, reduced cost, firm structure, reduced energy loss, and greatly improved construction efficiency; at the same time, the empty slot part can be reasonably utilized to arrange various materials according to needs. The present invention is used for the partition of underground shopping malls to divide large spaces into small spaces. Since it does not bear weight, the hollow part in the middle can be added with either thermal insulation foam board or sound insulation cotton to play a role of thermal insulation and sound insulation. It can be flexibly used to adapt to the development of underground construction. BRIEF DESCRIPTION OF THE DRAWINGS
