Abstract
Description
Technical Field
[0001] The utility model relates to the field of modular building structures, in particular to a square tube column module. Background Art
[0002] To ensure structural strength during stacking, hoisting, and transportation, an independent structural system is essential for each building module. In existing modular buildings, there are two primary approaches to the building and module structural systems. First, the building's structural system independently bears all loads, with the modules connected to the building's structural system as auxiliary components. Second, the modules' structural systems are interconnected to form the building's structural system.
[0003] Of the aforementioned approaches, the former approach offers a relatively simple module design, but the on-site installation workload is substantial and the building's structural system is difficult to conceal. The latter approach, on the other hand, presents a complex module design, requiring consideration of building sealing, structural connection strength, connection space, and design versatility. However, it offers greater economic advantages over the former approach. Currently, the latter approach is mostly based on a single, integrated design of a given module, lacking the design of smaller units, such as column and beam modules with a certain degree of integration. Utility Model Content
[0004] The purpose of the utility model is to provide a square pipe column module to solve the above problems, prevent joint leakage, ensure the space and connection strength of the connection operation, save costs, and have good uniformity and scalability.
[0005] Technical solution: The utility model provides a square tube column module, including: a square tube, a connecting part, the square tube is the outer frame part of the wall, connected to the wall keel or beam; the connecting part includes: a first connecting piece, a second connecting piece, a sealing strip, and an embedded nut. The first connecting piece is arranged on the outside of one side of the square tube, and the second connecting piece is arranged on the other side of the square tube, opposite to the first connecting piece. The sealing strip is arranged on the second connecting piece, and corresponding bolt holes are arranged on the first connecting piece and the second connecting piece. The embedded nut is arranged on the inner side of the first connecting piece and aligned with the bolt hole.
[0006] Furthermore, in the above-mentioned square tube column module, the first connecting member is an L-shaped shear-resistant connecting member, and the first connecting member and the square tube are fully welded on both sides in the length direction.
[0007] Furthermore, in the above-mentioned square tube column module, the second connecting member is a one-shaped connecting member, the width of which is equal to that of the first connecting member, and the second connecting member is aligned with the edge of the square tube and is fully welded.
[0008] Furthermore, in the aforementioned square column module, the sealing strip has a central notch facing the first connector, and has a cross-section that is thicker at both ends and thinner in the middle. When the second connector is slightly deformed by bolt tightening force, more pressure is distributed to the thicker areas at both ends of the sealing strip, thereby improving sealing performance.
[0009] Furthermore, in the above-mentioned square tube column module, a bolt hole is provided in the middle of the sealing strip, and the bolt hole corresponds to the position of the bolt hole on the second connecting member.
[0010] Furthermore, in the aforementioned square tube column module, the first connector is spaced a certain distance from the edge of the square tube, the distance being equal to the sum of the thickness of the second connector and the sealing strip. A reserved area is provided for self-connection. When the column module is self-connected, the second connector is placed in the reserved area and bolted to the first connector.
[0011] Furthermore, in the above-mentioned square tube column module, the sealing strip is made of rubber.
[0012] It can be seen from the above technical solution that the utility model has the following beneficial effects: the square tube column module described in the utility model has a simple structure and greater versatility, and the connection part has a certain structural strength, which helps to lighten the cross-section of the column load-bearing components and ensure the strength of the connection. The rubber seal is used to make the connection structure waterproof, which helps it to be used in other building modules. It is waterproof after installation without the need for additional on-site waterproofing treatment, which simplifies the on-site assembly process. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Example 1
[0018] like Figure 1-2The illustrated square tube column module comprises a square tube 1 and a connecting portion 2. The square tube 1 is the outer frame portion of the wall and is connected to the wall keel or beam. The connecting portion 2 comprises a first connecting member 21, a second connecting member 22, a sealing strip 23, and an embedded nut 24. The first connecting member 21 is disposed on the outside of one side of the square tube 1, and the second connecting member 22 is disposed on the other side of the square tube 1, opposite the first connecting member 21. The sealing strip 23 is disposed on the second connecting member 22. The first and second connecting members 21, 22 are provided with corresponding bolt holes. The embedded nut 24 is disposed on the inner side of the first connecting member 21 and aligned with the bolt holes. The structure is simple and is fastened by bolts, facilitating connection to the wall module. The first and second connecting members 21, 22 reduce the cross-section of the column module's load-bearing components and ensure the strength of the connection, saving costs. The sealing strip 23 is provided to provide a waterproof effect between the connecting structures.
[0019] In this embodiment, the first connector 21 is an L-shaped shear connector, fully welded to the square tube 1 along both sides of the length direction. The second connector 22 is a straight connector with a width equal to that of the first connector 21. The second connector 22 is aligned with the edge of the square tube 1 and fully welded. The L-shaped shear connector is used for structural connection and to resist shear forces parallel to the bolt direction.
[0020] Example 2
[0021] On the basis of Example 1, in this embodiment, as Figure 1 The square column module shown in the figure has a central notch on the sealing strip 23, which faces the first connector 21. The cross-section is thicker at the ends and thinner in the middle. The sealing strip 23 is made of rubber. When the second connector 22 is slightly deformed by the tightening force of the bolts, more pressure is distributed to the thicker areas at the ends of the sealing strip 23, improving sealing performance.
[0022] In this embodiment, a bolt hole is provided in the middle of the sealing strip 23 , and the position of the bolt hole corresponds to the position of the bolt hole on the second connecting member 22 .
[0023] In this embodiment, there is a certain distance between the first connecting member 21 and the edge of the square tube 1, which is equal to the sum of the thicknesses of the second connecting member 22 and the sealing strip 23; when the column modules are self-connected, the two column modules are arranged opposite to each other, the first connecting member 21 and the second connecting member 22 are fitted together, and the bolts pass through the bolt holes and are fixedly connected to the embedded nuts 24.
