Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a modular roof connection node for prefabricated buildings. Background Technology

[0002] Prefabricated construction is being used more and more widely in the construction industry, such as in high-rise and multi-story buildings. Modular prefabricated buildings not only require waterproof performance, but also require guaranteed appearance quality. They also require that most of the prefabrication work be completed in the factory to reduce the difficulty and uncertainty of on-site construction, improve construction efficiency, and ensure construction quality.

[0003] To avoid unforeseen severe weather (such as rain) during hoisting in existing modular buildings, lightweight steel roofs are used. These roofs cannot be prefabricated in a factory and must be installed on-site, increasing on-site workload and requiring at least three days for the entire construction period. Furthermore, lightweight steel roofs do not meet the construction requirements for modular buildings and present challenges related to transportation, construction progress, the large amount of on-site work, and difficulty in controlling on-site quality. Utility Model Content

[0004] The purpose of this utility model is to provide a modular roof connection node for prefabricated buildings, which can process the waterproof layer in the factory and eliminates the need for a light steel roof.

[0005] The technical solution of this utility model is: a modular roof connection node for prefabricated buildings, used to connect n sequentially spliced ​​main modules, where n≥2. The modular roof connection node for prefabricated buildings includes a connecting plate. Each main module has a connecting plate laid on its upper surface. One connecting plate connects two adjacent main modules simultaneously. The connecting plate forms a slope with gradually decreasing height from the first main module to the nth main module. The first main module is connected to the connecting plate by an angle aluminum, and an anchor bolt extending into the main module is provided on the angle aluminum. The nth main module is connected to the connecting plate by an anchor bolt and a gutter.

[0006] In the above solution, the connecting plates are placed on each main module, which can be prefabricated in the factory together with the main module. Each connecting plate connects two adjacent main modules at the same time. That is, during on-site assembly, the connecting plates cover the joints of the main modules. Before the roof is installed, the connecting plates are quickly overlapped to form a waterproof layer, which prevents rainwater from seeping into the room from the main modules, thus achieving good waterproof performance. Moreover, there is no need to use a light steel roof.

[0007] Preferably, the connecting plate on the nth main module includes a second plate, and the connecting plates on the remaining main modules include a first plate and a second plate. The first plate is laid on the upper surface of the main module and forms the slope. The second plate is laid on the upper surface of the first plate. The second plate of the upper level is pressed onto the second plate of the lower level. The second plate of the nth level is pressed onto the side surface of the main module and connected to the gutter. The second plate of the first level is connected to the angle aluminum.

[0008] Preferably, the first plate, the second plate, and the main module are fixed by anchor bolts.

[0009] Preferably, the anchor bolts on the first plate, the second plate, and the main module are covered by the second plate of the previous level. The previous level refers to the one above.

[0010] Preferably, the connecting plate further includes a third plate embedded in the first plate, the third plate being located at the seam between every two main modules.

[0011] Preferably, the first board is an extruded polystyrene board and the second board is a TPO board.

[0012] Preferably, sealant is provided between the angle aluminum and the main module, between the angle aluminum and the connecting plate, and between the gutter and the connecting plate.

[0013] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0014] 1. The connecting plates are set on each main module, which can be prefabricated in the factory together with the main module. Each connecting plate connects two adjacent main modules at the same time. That is, during on-site assembly, the connecting plates cover the joints of the main modules. Before the roof is installed, the connecting plates are quickly overlapped to form a waterproof layer, which prevents rainwater from seeping into the room from the main modules, thus achieving good waterproof performance. Moreover, there is no need to use a light steel roof.

[0015] Second, by placing the connecting plates on each main module, they can be prefabricated in the factory along with the main module. Furthermore, the fixing holes for the angle aluminum and gutter can be pre-drilled in the factory, thereby speeding up the on-site construction and reducing the construction cycle from 4-5 days to 4 hours, greatly improving work efficiency.

[0016] Third, most of the prefabrication of the main modules is carried out in the factory, and the quality is strictly controlled through the factory assembly line operation. On-site, only corresponding assembly and finishing are required, thereby ensuring the on-site construction progress and quality and reducing the number of on-site workers.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0023] like Figure 1 , Figure 2 As shown in the figure, this embodiment provides a modular roof connection node for prefabricated buildings, which is used to connect n main modules 1 that are sequentially spliced ​​along the Y direction. n≥2, and in this embodiment, n=3.

[0024] like Figure 3 Each main module 1 has a connecting plate 2 on its upper surface. The connecting plate 2 includes a first plate 21, a second plate 22, and a third plate 23. The first plate 21 is laid on the upper surface of the main module 1. Among the three main modules 1, the first plate 21 on the first main module 1 is the thickest, and then the thickness gradually decreases at each level (such as the second, third, etc.), so that the first plate 21 forms a slope with varying heights.

[0025] A third plate 23 is provided on the upper surface of the seam 7 between the two mating main modules 1, and the third plate 23 is embedded in the first plate 21. The second plate 22 is laid on the upper surfaces of the first plate 21 and the third plate 23.

[0026] The prefabricated structure of each main module 1 is as follows: The first main module 1 has the thickest first plate 21, and the perimeter of the first plate 21 is shorter than that of the main module 1. The perimeter of the second plate 22 extends horizontally to the outside of the main module 1 to form a hoisting position. The second plate 22, the first plate 21, and the main module 1 are fixed by anchor bolts 4 (nylon anchor bolts).

[0027] The prefabricated structure of the second main module 1 is as follows: At one end in the Y direction (closer to the first main module 1), a first plate 21 of the same thickness as the first plate 21 of the first main module 1 (e.g., 50mm thick) is installed. A thinner first plate 21 (e.g., 30mm thick) is then connected to the side of this first plate 21, forming a step with a height difference between the two first plates 21. The second plate 22 on the first main module 1 extends beyond the outer side of the 50mm thick first plate 21 on the second main module 1. Similarly, the first plate 21 on the second main module 1 is shorter than the main module 1 on all four sides. The end of the second plate 22 facing the third main module 1 and both ends in the X direction extend to the outside of the main module 1 to form a hoisting position. The second plate 22, the first plate 21, and the main module 1 are fixed by anchor bolts 4.

[0028] The prefabricated structure of the third main module 1 is as follows: One end of the third main module 1 (near the second main module 1) has a first plate 21 of the same thickness as the first plate 21 of the second main module 1 (e.g., 30mm). The first plate 21 is shorter than the main module 1 on all four sides, and extends only a short section in the Y direction. The connecting plate 2 of the third main module 1 consists only of a second plate 22. One end of the second plate 22 is fastened and fixed to the first plate 21 by anchor bolts 4. The other three sides of the second plate 22 extend to the outside of the third main module 1 to form a hoisting position. A short section of the first plate 21 on this main module 1 forms a step with a height difference from the second plate 22. The second plate 22 on the second main module 1 needs to extend beyond the outer side of the short section of the first plate 21 on this main module 1. The second plate 22 and the main module 1 are fixed by anchor bolts 4.

[0029] like Figure 3 , Figure 4 As shown, during on-site installation, multiple main modules 1 are hoisted and connected one by one. A third plate 23 is installed at the joint 7. The second plate 22 forming the hoisting position is bent on-site to cover the anchor bolt 4, and after wrapping the step, it is attached to the upper surface of the next-level second plate 22, and then fixed by on-site welding. The remaining second plates 22 on each main module 1 are bent on-site to wrap around the first plate 21 and the main module 1, or directly wrap around the main module 1.

[0030] A gutter 5 is installed on one outer end of the nth main module 1 in the Y direction (on the side away from the previous main module 1), and sealant 6 is applied between the gutter 5 and the second plate 22. Angle brackets 3 are installed on the remaining three sides of all main modules 1. The angle brackets 3 are placed outside the second plate 22, and anchor bolts 4 (covered with sealant 6) are installed on-site on the angle brackets 3, the second plate 22, and the main module 1, with sealant 6 applied around their perimeter.

[0031] The first plate 21 is an extruded polystyrene board, the second plate 22 is a TPO board (thermoplastic polyolefin), and the third plate 23 is a reinforced TPO roll.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
