Description

Technical Field

[0001] The utility model relates to the field of assembled steel structure buildings, in particular to a modular building connection node that is easy to assemble. Background Art

[0002] In recent years, as the Chinese government vigorously promotes prefabricated, low-carbon, and green buildings, modular buildings have become one of the important trends in the development of building industrialization. Modular buildings refer to the division of buildings into several space modules. All structures, equipment, pipelines, decorations, fixed furniture, facade decorations, etc. in the modules are assembled before being transported to the construction site. At the construction site, you only need to assemble the house like "building blocks". Modular buildings provide a new way of building construction, which has the advantages of high assembly rate, clean construction site, and fast construction speed.

[0003] Modular buildings rely on the connection between module units to form a structural whole to resist external loads, so the connection between modules should provide sufficient mechanical properties. In addition, the connection and installation between modules is a key factor affecting the efficiency and quality of modular building construction. The connections in modular buildings include the connection between modules and foundations, the connection between modules and lateral force resisting components, and the connection between module units. The connection between module units includes horizontal connection and vertical connection.

[0004] Modular buildings are not yet mature in my country. At present, the bolt connection nodes recommended in the Technical Code for Integrated Modular Buildings of Box-type Steel Structures T / CECS 641-2019 are as follows: Figure 6 As shown ( Figure 6 The figure shows the assembly of four modules). The connection nodes of this structure make it difficult to position the bolts of the hoisted modules at high altitudes. The bolt holes cannot be aligned in one hoisting operation, and the high-strength bolts are difficult to tighten. In addition, this connection structure makes it very easy for each module to form a structural sound transmission channel at the connection, resulting in poor sound insulation. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] This embodiment is described with respect to the assembly nodes between modules in a modular building. In this embodiment, a single module is a rectangular frame structure, such as Figure 2 As shown, a single module is mainly assembled by steel 1 and box-type node connection box 2. The steel 1 is usually H-shaped steel. Multiple steels 1 are combined into a rectangular frame, and a node connection box 2 is provided at each corner of the rectangular frame. The node connection box 2 is a rectangular hollow box structure. Bolt holes 3 and positioning holes 4 are respectively provided on the splicing surface of the node connection box 2 (the bolt holes 3 and the positioning holes 4 are located on the same surface). The positions and numbers of the bolt holes 3 and the positioning holes 4 are not limited and can be as follows: Figure 3 As shown, the positioning hole 4 is opened at the end away from the corner joint, and the bolt hole 3 is opened at the end close to the corner joint; Figure 4 As shown, the bolt hole 3 is opened at the end away from the corner joint, and the positioning hole 4 is opened at the end close to the corner joint. In order to facilitate the bolt tightening operation, an operation port 5 is also opened on the node connection box 2. The operation port 5 is not on the same surface as the bolt hole 3 on the node connection box 2. The operation port 5 can be Figure 3 As shown, it is opened on the outer side adjacent to the surface where the bolt hole 3 is located, and it can also be opened as shown in FIG. Figure 4 As shown, it is opened on the surface opposite to the surface where the bolt hole 3 is located. The operation port 5 needs to be connected with the internal cavity of the node connection box 2, so that the operator can easily reach into the operation port 5 to tighten the bolt.

[0026] The multiple modules of the above structure are assembled to form Figure 1 The partial structure of the modular building shown, in order to clearly show the modules connected to each other, Figure 1 Different colors are used to distinguish modules. The red module in the middle is a separate module, which is assembled with two green modules on the top and bottom, and with two yellow modules on the left and right. Figure 3 and Figure 4 The four modules of upper left module A, upper right module B, lower left module C, and lower right module D are captured for demonstration. When assembling the modules, they are assembled in a detachable manner through connecting components. The connecting components in this embodiment include a connecting plate 6 and a positioning plug 8. The connecting plate 6 needs to correspond to the positions of the bolt holes 3 and the positioning holes 4 on the node connection box 2, and corresponding bolt holes and positioning holes are also provided. The positioning plug 8 is used to be embedded in the positioning hole of the connecting plate 6. The two ends of the positioning plug 8 are exposed. The two ends of the positioning plug 8 are respectively inserted into the positioning holes 4 of the node connection box 2 on the two modules assembled up and down to achieve alignment between the modules.

[0027] In accordance with the above, the positioning plug 8 and the connecting plate 6 can be designed as split components (such as Figure 5 (a)), a combination of connecting components is formed by assembling on the construction site. The positioning plug block 8 and the connecting plate 6 can also be formed into an integrated structure during factory processing, eliminating the need for on-site assembly. The shape and structure of the positioning plug block 8 are not limited in the utility model, as long as it can be quickly aligned by plugging. Figure 5 Only four shapes of positioning plugs (8-1, 8-2, 8-3, 8-4) are listed in order to illustrate that the shapes of the positioning plugs 8 can be diverse.

[0028] In order to cut off the structural sound transmission path between modules and achieve better sound insulation effect for modular buildings, in this embodiment, rubber sound insulation pads 7 are also added between the modules that are assembled to each other, and bolt holes and positioning holes are also provided on the sound insulation pads 7. When assembling between modules, first hoist the lower module and put it in place, place the connecting plate 6 with the positioning plug 8 installed on the joint surface of the node connection box 2 of the lower module, and then lay the sound insulation pad 7 on the surface of the connecting plate 6, and then hoist the upper module, insert the positioning plug 8 into the positioning hole of the node connection box 2 of the upper module, and finally insert the high-strength bolt 9 into the bolt hole, and complete the assembly of the connection node by tightening the high-strength bolt 9 through the operation port 5.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
