Description

Technical Field

[0001] This utility model relates to the field of cold-formed steel modular building technology, and in particular to a hoisting and connection structure and a cold-formed steel modular building. Background Technology

[0002] In the field of modular construction and similar prefabricated construction, buildings are broken down into standardized modular units. After the entire process of prefabrication, including structure, decoration, and electromechanical systems, is completed in the factory, the units are transported to the site and assembled into a whole building through reliable connections. This approach has multiple advantages, including efficient construction, green and low-carbon construction, and controllable quality. Modular units form building units after assembly. As the demand for assembly increases, the building units need to be stacked before being connected to each other. Stacking building units requires hoisting.

[0003] In existing technologies, when hoisting building units, lifting rings need to be installed on the top of the building unit and connected to external hoisting equipment through the lifting rings before the building unit is hoisted. However, the lifting rings on the building unit are all fixedly connected to the building unit and are discarded after hoisting. At the same time, after hoisting, separately designed connectors are required for connection, which makes the connection structure design complex. This not only increases the difficulty and cost of building unit production, but also brings many inconveniences to on-site installation and positioning, and prolongs the construction period. Utility Model Content

[0004] The purpose of this utility model is to provide a hoisting and connection structure and a cold-formed steel modular building, which can solve the above-mentioned technical problems.

[0005] This utility model provides a hoisting and connection structure, including:

[0006] Mounting plate and first auxiliary plate, first longitudinal plate, second longitudinal plate and second auxiliary plate are arranged vertically on the four sides of the mounting plate in sequence;

[0007] An operating gap is formed between the first auxiliary plate and the second auxiliary plate; and an installation space is formed between the first auxiliary plate, the first longitudinal plate, the second longitudinal plate, and the second auxiliary plate.

[0008] A locking body is mounted on the mounting plate and placed within the mounting space; and the locking body is positioned opposite to the connection hole opened on the mounting plate.

[0009] The hoisting body is connected to the locking body after passing through the connecting hole at one end.

[0010] As a further technical solution, it also includes: a positioning body, which, after the lifting body and the locking body are separated, passes through the connecting hole and connects to the locking body.

[0011] As a further technical solution, the positioning body includes a connecting section and a protective section. One end of the connecting section passes through the connecting hole and is connected to the locking body, while the protective section is located at the other end of the connecting section.

[0012] As a further technical solution, the connecting section is a locking bolt, and the protective section is a cap nut.

[0013] As a further technical solution, the locking body is a fixed nut.

[0014] As a further technical solution, the fixing nut is welded to the mounting plate.

[0015] As a further technical solution, the lifting body is a lifting ring, and one end of the lifting ring is connected to the locking body through a lifting bolt.

[0016] As a further technical solution, the lifting ring is threadedly connected to the lifting bolt.

[0017] This utility model also proposes a cold-formed steel modular building, including a hoisting and connecting structure; a locking bolt is provided between adjacent mounting plates in the vertical direction, one end of the locking bolt is connected to the locking body, and a locking nut is provided on the other end.

[0018] As a further technical solution, a washer is provided between the locking nut and the mounting plate.

[0019] The technical solution of this utility model adopts a detachable connection design between the hoisting body, the locking body, and the mounting plate. After hoisting, the hoisting body can be removed and reused. There is no need to configure a special hoisting ring for each building unit, which greatly reduces material waste and lowers the cost of consumables and the investment in the disposal of waste hoisting rings.

[0020] Meanwhile, through the design of the mounting plate, auxiliary plate and locking body, while meeting the hoisting function, the installation space and the matching relationship of the locking body provide basic support for the connection of building units, eliminating the need for additional independent connecting parts, simplifying the overall design of building units, reducing the processing and assembly difficulty in the production stage and the operational complexity in the construction stage, and improving work efficiency.

[0021] In addition, the operating gap formed by the first auxiliary plate and the second auxiliary plate provides convenient space for the disassembly and assembly of the hoisting body and the alignment and adjustment of the building unit; the precise fit between the locking body and the connecting hole can serve as a connection positioning benchmark, reducing the time for on-site error adjustment, effectively solving the problem of inconvenient installation positioning, significantly shortening the construction cycle, and meeting the needs of efficient construction of modular buildings.

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] like Figure 1-5 As shown, the present invention proposes a hoisting and connection structure, comprising:

[0034] Mounting plate 101 and first auxiliary plate 102, first longitudinal plate 104, second longitudinal plate 105, and second auxiliary plate 103 arranged vertically on the four sides of mounting plate 101 in sequence; it should be noted that the lengths of the first auxiliary plate 102, first longitudinal plate 104, second longitudinal plate 105, and second auxiliary plate 103 are set according to the requirements of cold-formed steel modular building, and this utility model does not further limit them; in addition, an operating gap 106 is formed between the first auxiliary plate 102 and the second auxiliary plate 103; and an installation space is formed between the first auxiliary plate 102, first longitudinal plate 104, second longitudinal plate 105, and second auxiliary plate 103; during installation, the components in the installation space can be operated through the operating gap 106, which can effectively improve work efficiency; wherein, the range of the operating gap is 50-100mm, and the specific size of the first auxiliary plate 102 and the second auxiliary plate 103 can be adjusted according to the actual situation, which will not be further described in this utility model.

[0035] The locking body 200 is mounted on the mounting plate 101 and placed within the installation space; the locking body 200 is positioned opposite to the connection hole on the mounting plate 101; in this invention, the locking body 200 is fixed to the mounting plate 101 to ensure that the locking body 200 will not shift during subsequent use; in this invention, the preferred locking body 200 is a fixing nut; it is connected to the mounting plate 101 by welding, and the threaded hole on the locking nut 403 corresponds to the connection hole; one end of the lifting body 300 passes through the connection hole and connects to the locking body 200; after the lifting body 300 is installed, it can be connected to external lifting equipment, and under the action of the lifting body 300, the whole body moves simultaneously with the lifting equipment;

[0036] It should be noted that within the cold-formed steel modular building, the number of hoisting and connecting structures is set according to actual needs, and the number of hoisting bodies 300 is selected as needed to ensure that the cold-formed steel modular building can be hoisted to the designated position by hoisting equipment with the cooperation of multiple hoisting bodies 300; the number of hoisting bodies 300 is determined according to actual usage requirements, and this utility model does not further limit it.

[0037] The technical solution of this utility model adopts a detachable connection design between the hoisting body 300, the locking body 200, and the mounting plate 101. After hoisting, the hoisting body 300 can be removed and reused. There is no need to configure a special hoisting ring 301 for each building unit, which greatly reduces material waste and lowers the cost of consumables and the investment in the disposal of waste hoisting rings 301.

[0038] Meanwhile, through the design of the mounting plate 101, auxiliary plate and locking body 200, while satisfying the hoisting function, the installation space and the matching relationship of the locking body 200 provide basic support for the connection of building units, eliminating the need for additional independent connecting parts, simplifying the overall design of building units, reducing the processing and assembly difficulty in the production stage and the operational complexity in the construction stage, and improving work efficiency.

[0039] In addition, the operating gap 106 formed by the first auxiliary plate 102 and the second auxiliary plate 103 provides convenient space for the disassembly and assembly of the hoisting body 300 and the alignment and adjustment of the building unit; the precise fit between the locking body 200 and the connecting hole can serve as a connection positioning benchmark, reduce the time for on-site error adjustment, effectively solve the problem of inconvenient installation positioning, significantly shorten the construction cycle, and meet the needs of efficient construction of modular buildings.

[0040] like Figure 2As shown, this utility model also includes a positioning body. After the lifting body 300 is separated from the locking body 200, the positioning body passes through the connecting hole and connects to the locking body 200. Specifically, after the lifting is completed, the lifting body 300 can be separated from the locking body 200 and taken out for later use or for other purposes. After the lifting body 300 is taken out, the positioning body is placed in the installation space through the operating gap 106 and connected to the locking body 200. After the positioning body is connected, one end of the positioning body is placed on the outside of the mounting plate 101. In this way, during subsequent installation, the positioning body can play a positioning role. When installing other components, the position of the mounting hole can be accurately obtained, improving the overall installation efficiency.

[0041] The positioning body includes a connecting section and a protective section. One end of the connecting section passes through the connecting hole and connects to the locking body 200. The protective section is located at the other end of the connecting section. In this utility model, the connecting section is a locking bolt 401 and the protective section is a cap nut 402. When connecting, the locking bolt 401 is passed through the locking body 200 and threadedly connected to the locking body 200 until the nut of the locking bolt 401 contacts the locking body 200. The cap nut 402 is then connected to the end of the locking bolt 401 that is outside the installation space to protect that end and prevent damage to the threads caused by collisions during subsequent installation, which would affect the subsequent connection.

[0042] like Figure 1-3 As shown, the lifting body 300 is a lifting ring 301, and one end of the lifting ring 301 is connected to the locking body 200 through a lifting bolt 302. Specifically, before lifting, the lifting bolt 302 is passed through the connecting hole and threadedly connected to the locking body 200 to fix the lifting ring 301. During lifting, the lifting equipment is connected to the lifting ring 301 to perform the corresponding lifting operation. Of course, in this utility model, the lifting ring 301 and the lifting bolt 302 can be an integral structure. When lifting is not required, the lifting ring 301 and the lifting bolt 302 can be disassembled and a positioning body can be installed inside the locking body 200.

[0043] Of course, in another embodiment of this utility model, the lifting ring 301 is threadedly connected to the lifting bolt 302; thus, after the lifting is completed, the lifting ring 301 and the lifting bolt 302 can be separated, and a cap nut 402 can be installed on the connection end of the lifting bolt 302 and the lifting ring 301. The lifting bolt 302 replaces the locking bolt 401, so that the locking bolt 401 does not need to be installed again.

[0044] This utility model also proposes a cold-formed steel modular building, including a hoisting and connecting structure; a locking bolt 401 is provided between adjacent mounting plates 101 in the vertical direction, one end of the locking bolt 401 is connected to the locking body 200, and a locking nut 403 is provided on the other end; as Figure 4 and Figure 5As shown, after the adjacent mounting plates 101 come into contact, the cap nut 402 on the locking bolt 401 is removed, and the locking nut 403 is installed. When installing the locking nut 403, it can be operated through the operating gap 106. After the locking nut 403 is fixed, the adjacent mounting plates 101 are fixed together. The connection hole opened on the mounting plate 101 has two uses: it is used to install the lifting ring 301 during hoisting. After the hoisting is completed and the lifting ring 301 is removed, the locking body 200 can also be used to connect with the bolts of the upper column base to solve the column connection problem between the upper and lower boxes.

[0045] In addition, to reduce the pressure of the locking nut 403 on the mounting plate 101, a pad 500 is provided between the locking nut 403 and the mounting plate 101 in this utility model; the pad 500 prevents the locking nut 403 from directly contacting the mounting plate 101 and avoids wear on the mounting plate 101; specifically, the pad 500 is a round or square metal pad, the material of which is the same as that of the mounting plate 101, the thickness is 2-4mm, and the area is not less than the supporting area of ​​the locking nut 403.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
