[0002] Currently, in the prefabricated buildings that fall under the category of light steel structures, the splicing of medium-sized building modules of 1 to 3 meters requires consideration of complex technical details such as waterproofing, thermal insulation, and pipeline splicing, as well as comprehensive cost factors, including auxiliary technical details such as transportation, installation, and internal and external matching.

[0003] The prior art has the following problems:

[0004] 1. Buildings that generally adopt modular stacking structures (taking container-based buildings as an example) have always faced the problem of low sealing reliability and structural defects despite various assembly methods. In the connection method of large contact surfaces and line segments, large-span node bolt connections or customized angle code connectors or on-site welding are mainly used. It is difficult to ensure the thermal insulation performance while ensuring the sealing, and it is also difficult to ensure the overall shear resistance, torsion resistance, and tensile strength after the connection, leaving unnecessary hidden dangers after installation;

[0005] 2. Due to the limitations of the structural method, in complex construction areas (generally referring to remote, rugged, and narrow areas), it is difficult to prefabricate large modules due to transportation accessibility issues. Therefore, most of the processes and techniques are completed in the factory, and then transported to the site for assembly in smaller pieces, which increases the manpower, process steps, and error correction costs of on-site construction, affecting the construction progress and construction quality results.

DETAILED DESCRIPTION

[0038] Example 1

[0039] Please refer to Figure 1-Figure 6 , Figure 1-Figure 6 An embodiment of the present application is shown.

[0040] This embodiment provides a building module sealed splicing structure, which includes a channel steel 1 and a channel steel 2. Figure 1 As shown, the open end of channel steel 1 is arranged opposite to the open end of channel steel 2, and sealing strip 1 3 and sealing strip 2 4 are abutted between channel steel 1 and channel steel 2. Channel steel 1 and channel steel 2 are both penetrated by a plurality of bolts 5, and the bolts 5 are connected with nuts 6.

[0041] When in use, channel steel 1 and channel steel 2 are made of 14A hot-dip galvanized channel steel, which has the characteristics of ensuring excellent overall stability in terms of yield resistance, flatness, shear resistance and other indicators when realizing small module connection. Bolt 5 is made of 12.9 grade The high-strength bolt 5 is equipped with a nut 6.

[0042] It should be noted that the use of 12.9 grade high-strength bolts 5 are widely used rather than special materials. On the one hand, they can effectively reduce the overall cost, and on the other hand, they can reduce the difficulty of operation during installation and improve the installation efficiency and accuracy.

[0043] Through the above technical solution, a minimalist construction structure and a more reliable connection method are adopted, so that the overall seismic strength after splicing is not weaker than that of the container building, especially the shear and tensile resistance are reliably guaranteed; under the simple action of the sealing strips at the joints, the heat insulation effect of the broken bridge barrier is better.

[0044] This embodiment also provides a building module, which includes the above-mentioned building module sealed splicing structure 100, such as Figure 5As shown, the sealed splicing structure 100 of the building modules is arranged in a ring shape, and a plurality of outer purlins 102 are threadedly connected and / or welded to the sealed splicing structure 100 of the building modules, and the outer purlins 102 are riveted with the outer decorative panels 200 .

[0045] When in use, first use 14A hot-dip galvanized channel steel to bend and weld channel steel 1 and channel steel 2 of the D-shaped frame, turn the opening sides of channel steel 1 and channel steel 2 outward, weld a number of 50mm*50mm square tube purlins between channel steel 1 and channel steel 2 as outer purlins 102, and rivet a number of exterior panels 200 on the outer side of the outer purlin 102 to complete the prefabrication of a single building module. The prefabricated building module has a length of 2.4 meters per cabin section, and a single cabin section weighs 350kg to 550kg, and can be transported by a 4.2-meter trolley or forklift.

[0046] It should be noted that on short and medium-distance sections, an ordinary 4.2m truck can transport a single compartment, and a 6.8m truck can transport two compartments. Figure 6 As shown, long-distance trunk transport can transport four compartments at a time using a trailer.

[0047] When splicing, after the channel steel 1 and the channel steel 2 2 of the two building modules are connected with the bolts 5, the sealing strip 1 3 and the sealing strip 2 4 are respectively inserted into the inside and outside, and then the nuts 6 are tightened so that the channel steel 1 and the channel steel 2 2 squeeze and fix the sealing strip 1 3 and the sealing strip 2 4.

[0048] Through the above technical solution, the structural characteristics of being split into sections make it possible to use transportation methods such as carts or forklifts for transportation on unconventional roads; the constraints on the construction site caused by the installation of equipment are greatly reduced.

[0049] As a preferred embodiment, the sealed splicing structure 100 of the building modules is threadedly connected and / or welded with a plurality of inner purlins 103, and the inner purlins 103 are riveted with interior panels.

[0050] When in use, select interior panels with appropriate patterns for riveting according to the requirements of the interior surface.

[0051] Through the above technical solution, the inner purlin 103 is used to connect the interior decoration panels, thereby improving the customizability of the interior decoration of the module.

[0052] As a preferred implementation, the sealed splicing structure 100 of the building modules is welded with a plurality of I-shaped beams 101 , and floors are riveted above the I-shaped beams 101 .

[0053] When in use, a horizontal connecting surface (omitted in the drawings) is bent at the opening of the V-shaped steel for riveting with the floor, and the floor is made of cold-rolled steel plate or synthetic plate.

[0054] Through the above technical solution, the "J"-shaped beam 101 is used to support the floor, thereby increasing the load-bearing capacity of the module.

[0055] As a preferred implementation, the sealed splicing structure 100 of the building modules is detachably connected to a frame 300 , and a functional surface 400 is connected to the inner side of the frame 300 .

[0056] When in use, bolts 5 or nuts 6 can be pre-welded in the frame 300, and then the frame 300 and the channel steel 1 or the channel steel 2 2 are spliced ​​and fastened by connecting with bolts and nuts. If necessary, a sealing strip can be added, and the glass window and / or door frame can be glued to the inside of the frame 300.

[0057] Through the above technical solution, by replacing different functional surfaces 400, functional surfaces 400 such as window frames or doors and windows can be installed.

[0058] As a preferred implementation, the sealed building module splicing structure 100 is provided with threading holes 104 .

[0059] When in use, the threading hole 104 is specifically opened in the space between the inner purlin 103 and the outer purlin 102, so that the pipeline can be buried between the inner and outer decorative panels.

[0060] Through the above technical solution, by using the threading holes 104 set on the splicing structure, the complexity of connecting the complex pipelines of each module compartment is greatly reduced, and the accuracy is guaranteed.

[0064] When in use, a mounting opening is cut in the middle of the channel steel, and then a steel plate is welded at the opening corresponding to the mounting opening as a mounting plate. Two through holes are opened on the steel plate, and the openings of the two sections of channel steel are opposite to each other. Then, bolts 5 and nuts 6 are installed through the mounting opening for connection.

[0065] It should be noted that, because the openings of the two sections of channel steel need to abut against the sealing strip, a gap will be formed between the mounting plate 106 and the mounting plate 2 108. In order to prevent the mounting plate 106 and / or the mounting plate 2 108 from being pulled and deformed when the bolts 5 and nuts 6 are tightened, causing desoldering or affecting the secondary installation, a washer (not shown in the drawings) can be installed between the mounting plate 106 and the mounting plate 2 108 to ensure the locking force while preventing the mounting plate from being deformed. Figure 7 It is only used to illustrate the connection relationship and is not used as a limit on the length of the channel steel.

[0066] Through the above technical solution, an embedded mounting plate is used for bolts 5 to connect two sections of channel steel, which reduces the protrusion of the bolts 5 and nuts 6, enhances the compactness of the splicing structure, and improves space utilization.

[0067] This embodiment also provides a building module, which includes the above-mentioned building module sealed splicing structure 100, and the rest of the structure is the same as that of embodiment 1.
