Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, specifically relating to a wall fixing structure for prefabricated exterior wall systems. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] In existing technologies, considering that steel structures have advantages such as high material strength, good plasticity and toughness, recyclability, and environmental friendliness, their application in building structures can reduce structural self-weight, improve structural seismic performance, and speed up construction. As a result, their use is increasing.

[0004] Using steel structures to construct composite frames is an existing technology:

[0005] The applicant published a utility model patent entitled "Four-corner connected corrugated steel plate shear wall" (authorization announcement number: CN215054259U) on June 23, 2021, which forms a frame through frame columns and frame beams.

[0006] The applicant published a utility model patent entitled "A Composite Frame with Corrugated Steel Plate" (authorization announcement number: CN218911737U) on December 8, 2022, which forms a frame through steel beams and steel columns.

[0007] The applicant published a utility model patent entitled "Hybrid Frame of Support and Corrugated Steel Plate Wall" (authorization announcement number: CN220058440U) on April 26, 2023, which forms a frame through frame beams and steel columns.

[0008] How to stably install factory-processed modular walls onto steel beams is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0009] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art, and to provide a wall fixing structure for prefabricated exterior wall systems. This structure can stably install modular walls processed in the factory onto the steel beams of the prefabricated exterior wall system on site, which can shorten the construction cycle, reduce on-site labor costs, improve the economic efficiency of the building, and prevent damage to the wall structure itself.

[0010] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0011] The wall fixing structure for prefabricated exterior wall systems is characterized by comprising components, limiting components, and connectors. The components are fixed on the steel beams of the prefabricated exterior wall system. The limiting components are installed on the components and are used to limit the outer side of the wall of the prefabricated exterior wall system. The connectors are fixed on the components and are used to limit the inner side of the wall of the prefabricated exterior wall system, so that the wall of the prefabricated exterior wall system is set vertically.

[0012] Furthermore, the limiting component uses a through-bolt, which includes a bolt part one and a bolt part two connected together. Bolt part one limits the component, and the upper end of the wall is limited by bolt part two. The through-bolt is cylindrical, and when it limits the wall, it makes point and surface contact, so the through-bolt is less affected by unevenness of the wall; moreover, the through-bolt is low in cost, easy to manufacture, improves construction efficiency, and saves construction costs.

[0013] Furthermore, the component is provided with a limiting hole, and the bolt part passes through the limiting hole. The bolt part is provided with a nut, and the component is limited between the two nuts of the bolt part. By changing the position of the nuts, the position of the through bolt at the component can be adjusted. When the through bolt limits the wall, the wall is set at the set position on the floor slab, improving the overall integrity.

[0014] Furthermore, the limiting component adopts a limiting plate, which includes a first limiting part and a second limiting part connected to each other. The first limiting part is fixed to the component, and the upper end of the wall is limited by the second limiting part. The limiting plate can limit the upper end of the wall and can withstand the force applied by the wall, so that the modular wall can be set vertically. The limiting plate is easy to process and can be installed quickly, improving construction efficiency.

[0015] Furthermore, the limiting part is fixed to the component by welding.

[0016] Furthermore, the component includes a plate and folded edges, with the folded edges located on both sides of the plate, giving the component a U-shape and good strength.

[0017] Furthermore, the component is provided with a through hole, and the connector is provided with a fixing bolt. The fixing bolt passes through the through hole and moves along the length of the steel beam in the through hole. The fixing bolt is provided with a nut, which allows the connector to be adjusted on the component along the length of the steel beam, facilitating the connection between the wall and the connector.

[0018] Furthermore, the connector has two through holes, a second and a third. A first fixing bolt passes through the second through hole, allowing the connector to move along the width of the steel beam on the first fixing bolt. The wall has a second fixing bolt, which passes through the third through hole, allowing the connector to move along the height of the steel beam on the second fixing bolt. The second fixing bolt has a nut. This allows the connector to be adjusted along the width and height of the steel beam, enabling it to act on the inner side of the wall and fix a wall of a certain thickness.

[0019] Furthermore, the connector is L-shaped.

[0020] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0021] (1) The prefabricated exterior wall system of this utility model is made of steel beams, steel columns and floor slabs. The wall is a modular wall processed in the factory. After the wall is processed, it is transported to the construction site. The wall of this utility model is made of light steel keel, which has the effect of energy saving and environmental protection.

[0022] To achieve rapid and stable installation of modular walls, this invention fixes components at the steel beams, then installs limiting devices at the components, and subsequently limits the upper end of the wall to the limiting devices, thus confining the limiting devices to the outer side of the prefabricated exterior wall system. Finally, connectors are installed at the components, confining them to the inner side of the prefabricated exterior wall system, completing the stable connection between the modular wall and the steel beams. This shortens the construction cycle, reduces on-site labor costs, improves the economic efficiency of the building, and prevents damage to the wall structure itself.

[0023] (2) The limiting component of this utility model uses two methods to limit the wall:

[0024] Method 1: The limiting component uses a through-bolt. The through-bolt consists of two connected bolt parts. Bolt part one limits the wall component, and the upper end of the wall is limited by bolt part two. The through-bolt can limit the upper end of the wall and can withstand the force applied by the wall, allowing the modular wall to be installed vertically. The through-bolt is cylindrical, and when limiting the wall, it is in point and surface contact, so the through-bolt is less affected by unevenness of the wall. Moreover, the through-bolt is low in cost, easy to manufacture, improves construction efficiency, and saves construction costs.

[0025] The component of this utility model is provided with a limiting hole, and a bolt part passes through the limiting hole. The bolt part is provided with a nut, and the component is limited between the two nuts of the bolt part. The position of the through bolt at the component can be adjusted. When the through bolt limits the wall, the wall is set at the set position on the floor slab, improving the overall integrity.

[0026] Method 2: The limiting component uses a limiting plate, which includes a first limiting part and a second limiting part connected together. The first limiting part is fixed to the component, and the upper end of the wall is limited by the second limiting part. The limiting plate can limit the upper end of the wall and can withstand the force applied by the wall, allowing the modular wall to be set vertically. The limiting plate is easy to process and quick to install, improving construction efficiency. Attached Figure Description

Detailed Implementation

[0044] like Figure 7 The diagram shows a prefabricated exterior wall system, comprising steel beam a, steel column b, floor slab c, and wall f. The wall f of this invention is constructed using a lightweight steel keel, which is processed in a factory to obtain a modular wall f. This allows for control over the processing quality of wall f, shortens the on-site construction cycle, and the lightweight steel keel wall system offers energy-saving and environmentally friendly benefits. Steel beam a and floor slab c are fixed vertically to steel column b, forming a frame with cavities e (such as...). Figure 8 (As shown). The outer side of wall f is equipped with dry-hanging fittings, on which keels are installed. The keels are Z-shaped, and the decorative panels are fixed to the keels. The inner side of wall f is equipped with a steel structure. The steel structure of this utility model is square steel. Wall panel d has washing holes, and self-tapping screws are installed between the washing holes and the square steel.

[0045] like Figures 1 to 15 As shown, this utility model is a wall fixing structure for a prefabricated exterior wall system, which can fix the wall f and the steel beam a.

[0046] Example 1,

[0047] This utility model includes a component 1, a limiting component 2, and a connecting component 3. The component 1 is fixed to the steel beam a of the prefabricated exterior wall system by welding. The component 1 includes a plate 4 and flanges 5. The flanges 5 are located on both sides of the plate 4. The component 1 can be made into a U-shape by stamping. The component 1 has good strength.

[0048] The limiting member 2 is installed on the component 1, and the limiting member 2 is used to limit the outer side of the wall f of the prefabricated exterior wall system. The connecting member 3 is fixed on the component 1, and the connecting member 3 is used to limit the inner side of the wall f of the prefabricated exterior wall system, so that the wall f of the prefabricated exterior wall system is set vertically.

[0049] In Embodiment 1, the limiting component 2 is a through-bolt 2, which includes a bolt part 6 and a bolt part 7. The bolt part 6 and the bolt part 7 are formed by bending. The bolt part 6 is horizontally limited on the component 1, and the upper end of the wall f is limited on the vertical bolt part 7. The through-bolt 2 can limit the upper end of the wall f and can withstand the force applied by the wall f, so that the modular wall f is set vertically. The through-bolt 2 is cylindrical, and when it limits the wall f, it is in point and surface contact, so the through-bolt 2 is less affected by the unevenness of the wall f. Moreover, the through-bolt 2 is low in cost, easy to manufacture, improves construction efficiency, and saves construction costs.

[0050] The flange 5 of component 1 is provided with a limiting hole 9. Bolt part 6 passes through the limiting hole 9 and is provided with a nut 8. A single through bolt 2 uses two nuts 8 to limit component 1. By adjusting the position of the nuts 8 on bolt part 6, the position of through bolt 2 at component 1 can be adjusted. When through bolt 2 limits wall f, wall f is set at the set position of floor slab c, improving the overall integrity and keeping wall f vertical.

[0051] The plate 4 of component 1 has a through hole 10 and an enlarged hole 11. The connector 3 has a fixing bolt 12. Component 1 is U-shaped, and there is a space between it and the steel beam a. The fixing bolt 12 is installed in the through hole 10 after passing through the enlarged hole 11. The fixing bolt 12 extends into the space to satisfy the installation of the fixing bolt 12. The fixing bolt 12 moves along the length of the steel beam a in the through hole 10. The fixing bolt 12 has a nut 13, which allows the connector 3 to be adjusted on component 1 along the length of the steel beam a, facilitating the connection between the wall f and the connector 3.

[0052] The L-shaped connector 3 has two through holes, 15 and 14. A fixing bolt 12 passes through the second through hole 15, allowing the connector 3 to move along the width of the steel beam a on the fixing bolt 12, facilitating the connection between the wall f and the connector 3. The wall f has a fixing bolt 19, which passes through the third through hole 14, allowing the connector 3 to move along the height of the steel beam a on the fixing bolt 19. The fixing bolt 19 has a nut 20. This allows the connector 3 to be adjusted along the width and height of the steel beam a on the component 1, enabling the connector 3 to act on the inner side of the wall f and fix a wall f of a certain thickness.

[0053] Example 2,

[0054] Based on the structure of Embodiment 1, Embodiment 2 replaces the through bolt 2 used in the limiting member 2 with a limiting plate.

[0055] The limiting plate includes a first limiting part 16 and a second limiting part 17, which are formed by bending. The first limiting part 16 is horizontally fixed to the component 1 by welding, and the upper end of the wall f is limited by the vertical limiting part 17. The limiting plate can limit the upper end of the wall f and can withstand the force applied by the wall f, so that the modular wall f is set vertically. The limiting plate is easy to process and quick to install, improving construction efficiency. The first limiting part 16 has an opening 18. When installing the fixing bolt 12, the fixing bolt 12 passes through the opening 18 and is limited by the first limiting part 16.

[0056] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
