Description

Technical Field

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

[0002] With the acceleration of my country's construction industrialization process, prefabricated buildings have become a key construction method promoted due to their advantages such as fast construction speed, less environmental pollution, and controllable quality. However, the existing roof connection structures of prefabricated houses still have many shortcomings:

[0003] First, traditional roof connections mostly use welding or on-site drilling and bolt fixing, which is not only inefficient and requires professional welders and large equipment, but also the heat-affected zone of welding is prone to deformation of profiles and damage to the coating, resulting in the risk of rust and cracking after long-term use.

[0004] Secondly, the connection between the roof panels and the sloping panels mostly relies on screws or clips, requiring multiple people to work together and using cumbersome tools. Furthermore, they are prone to loosening and falling off under strong winds or earthquakes, posing a safety risk.

[0005] Furthermore, the existing structure lacks effective elastic buffering and anti-slip design, and temperature difference deformation can easily cause roof panels to warp, leak, or make abnormal noises.

[0006] Therefore, it is necessary to further improve the roof connection mechanism for prefabricated houses. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the existing defects and provide a roof connection mechanism for prefabricated houses. By combining a T-shaped groove modular frame, magnetic locking, elastic support and rigid limit, the mechanism achieves long-term stability of roof installation, improves the efficiency of prefabricated roof installation, and effectively solves the problems in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a roof connection mechanism for prefabricated houses, including a crossbeam and a horizontal plate. The outer side of the crossbeam is uniformly provided with a first T-shaped groove along its length. The lower surface of the horizontal plate is provided with a T-shaped block and is assembled into the first T-shaped groove on the upper surface of the crossbeam. The lower surface of the horizontal plate is provided with a second T-shaped groove on the left and right sides respectively. Angle brackets are respectively assembled into the first T-shaped grooves on the left and right sides of the crossbeam by fixing components. The angle brackets are assembled into the second T-shaped grooves on the lower surface of the horizontal plate by fixing components, so as to achieve a fixed connection between the crossbeam and the horizontal plate.

[0009] The upper surface of the horizontal plate is fixedly connected to the inclined plate by the connecting frame. The upper surface of the inclined plate is equipped with the roof plate by the limiting component. The lower surface of the roof plate is provided with the locking component. The left and right sides of the inclined plate are provided with locking grooves. The locking component is locked to the second permanent magnet in the locking groove by magnetic attraction.

[0010] Preferably, the horizontal plate has a strip groove on its upper surface, the strip groove is filled with a supporting sponge strip, the supporting sponge strip elastically abuts against the lower surface of the roof plate, and the horizontal plate and the roof plate have corresponding pin holes, in which a fixing pin passes.

[0011] Preferably, the fixing component includes a T-nut and an internal hex bolt, the T-nut being slidably disposed in a first T-groove and a second T-groove, and the internal hex bolt passing through the mounting hole of the bracket and threadedly connected to the T-nut.

[0012] Preferably, the limiting component includes a groove and a limiting strip. The groove is formed on the upper surface of the inclined panel, and the limiting strip is set on the lower surface of the roof panel. The limiting strip is slidably connected along the groove to facilitate the limiting and assembly of the roof panel.

[0013] Preferably, the locking assembly includes a latch, a mounting shell, and a first permanent magnet. The mounting shell is fixedly installed on the lower surface of the roof panel, the latch is slidably installed inside the mounting shell, and the first permanent magnet is disposed in the mounting groove of the latch, and the first permanent magnet is magnetically attracted to a second permanent magnet in the locking groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses T-slots, corner brackets, and T-nuts to fix the cross beam and horizontal plate at a cross joint, eliminating the need for welding and drilling. The T-nuts can slide and position freely within the slots, adapting to construction errors and resulting in high installation efficiency. It is particularly suitable for rapid construction scenarios such as emergency housing and temporary exhibition halls.

[0016] The roof panel of this utility model adopts a limiting strip and a sliding groove for guidance and pushing in. With the first permanent magnet driving the locking tongue to automatically insert into the locking groove, the installation is completed when a "click" is heard. It can be installed quickly. The supporting sponge strip provides compression elastic support and absorbs temperature difference deformation. The fixing pin passes through the double-layer pin hole to form a hard limit, which solves the problems of loosening of traditional buckles and screw falling off. Attached Figure Description

[0024] Please see Figure 1-4 This utility model provides a technical solution: a roof connection mechanism for prefabricated houses, including a crossbeam 10 and a horizontal plate 1. The outer side of the crossbeam 10 is evenly provided with a first T-shaped groove 8 along the length direction. The lower surface of the horizontal plate 1 is provided with a T-shaped block 14 and is assembled in the first T-shaped groove 8 on the upper surface of the crossbeam 10. The lower surface of the horizontal plate 1 is provided with a second T-shaped groove 13 on the left and right sides respectively. Angle brackets 9 are respectively assembled in the first T-shaped grooves 8 on the left and right sides of the crossbeam 10 through fixing components 7. The angle brackets 9 are assembled in the second T-shaped grooves 13 on the lower surface of the horizontal plate 1 through fixing components 7, so as to realize the fixed connection between the crossbeam 10 and the horizontal plate 1.

[0025] Specifically, the crossbeam 10 serves as the main load-bearing frame and achieves multi-directional modular docking through the evenly distributed first T-shaped grooves 8; the T-shaped block 14 on the lower surface of the horizontal plate 1 is inserted into the first T-shaped groove 8 at the top of the crossbeam 10 to form longitudinal positioning; the corner bracket 9 spans the side of the crossbeam 10 and the lower surface of the horizontal plate 1, and is locked in both directions by the fixing component 7 to form a stable cross-shaped connection node.

[0026] The T-block 14 and the first T-slot 8 are fitted with a clearance to ensure smooth insertion without wobbling. The first T-slot 8 and the second T-slot 13 provide standardized tracks. The T-nut 701 can slide and be positioned at any position in the slot. The internal hex bolt 702 provides adjustable preload.

[0027] The corner bracket 9 is a 90° L-shaped aluminum alloy steel plate. The first T-slot 8 and the second T-slot 13 provide standardized connection interfaces. The corner bracket 9 and the T-nut 701 achieve mechanical fixation without welding. The internal hex bolt 702 and the T-nut 701 are made of stainless steel finished parts, which are beautiful and rust-proof. No electric welding is required on site, and two people can complete the assembly of four nodes in 30 minutes.

[0028] The crossbeam 10 can be made of 6061-T6 aluminum alloy extruded profile, and the horizontal plate 1 can be made of SMC molded plate or aluminum alloy die casting.

[0029] The upper surface of the horizontal plate 1 is fixedly connected to the inclined plate 3 by the connecting frame 2. The connecting frame 2 is a cross-shaped support component, which is fixed to the upper surface of the horizontal plate 1 and the lower surface of the inclined plate 3 by welding. After the inclined plate 3 is welded, the top surface should be a slope of 15° to 45° to form the roof drainage slope.

[0030] The horizontal plate 1 is integrated with the inclined plate 3 via the connecting frame 2. The height of the connecting frame 2 and the tilt angle of the inclined plate 3 can be customized to adapt to the rainfall requirements of different regions. Installation does not require welding and can be directly installed, improving installation efficiency.

[0031] The roof panel 5 is installed on the upper surface of the inclined panel 3 by means of the limiting component 11. The limiting component 11 consists of a sliding groove 1101 and a limiting strip 1102, forming a dovetail-shaped guide rail structure. The roof panel 5 is slidably installed along the upper surface of the inclined panel 3 to prevent lateral displacement and overturning.

[0032] One person can complete the installation of the roof panel with one hand, improving installation efficiency; the dovetail-shaped guide rail structure is windproof and safe.

[0033] A locking component 12 is provided on the lower surface of the roof panel 5, and locking grooves 15 are provided on both the left and right sides of the inclined panel 3. The locking component 12 is locked to the second permanent magnet in the locking groove 15 by magnetic attraction.

[0034] Specifically, when the roof panel 5 is pushed into place, the first permanent magnet 1203 and the second permanent magnet in the locking groove 15 generate magnetic attraction, which drives the locking tongue 1201 to automatically extend and insert into the locking groove 15, forming a mechanical lock.

[0035] Furthermore, a strip groove is provided on the upper surface of the horizontal plate 1, and a supporting sponge strip 4 is filled in the strip groove. The supporting sponge strip 4 elastically abuts against the lower surface of the roof plate 5. Corresponding pin holes are provided on the horizontal plate 1 and the roof plate 5, and a fixing pin 6 is inserted into the pin hole.

[0036] Specifically, the supporting sponge strip 4 is bonded and filled into the strip groove with a compression of 25%, providing uniform elastic support for the roof panel 5, absorbing the micro-deformation of the roof panel 5 caused by temperature difference or load, reducing vibration and noise, and the fixing pin 6 passes through the double-layer pin hole to form a rigid limit to prevent the roof panel 5 from sliding along the slope direction.

[0037] The pin holes of the roof panel 5 are opened in the splicing groove of the roof panel 5 so that the fixing pin 6 in the pin hole can be pressed tightly after the next roof panel 5 is installed in place, thereby increasing the connection strength and ensuring the connection stability.

[0038] The double-insurance design (elasticity + rigidity) prevents the roof panel 5 from warping and slipping; the sponge strip is replaceable, with low maintenance costs, and the supporting sponge strip 4 can be made of closed-cell EPDM foam strip or PU soft foam strip.

[0039] Furthermore, the fixing component 7 includes a T-nut 701 and an internal hex bolt 702. The T-nut 701 is slidably disposed in the first T-groove 8 and the second T-groove 13. The internal hex bolt 702 passes through the mounting hole of the corner bracket 9 and is threadedly connected to the T-nut 701.

[0040] Specifically, the T-nut 701 can slide freely along its length in the first T-groove 8 and the second T-groove 13. After the hexagon socket bolt 702 is tightened, the T-nut 701 is pulled and fixed in the groove, forming an adjustable mechanical locking mechanism.

[0041] Furthermore, the limiting component 11 includes a groove 1101 and a limiting strip 1102. The groove 1101 is formed on the upper surface of the inclined panel 3, and the limiting strip 1102 is set on the lower surface of the roof panel 5. The limiting strip 1102 slides along the groove 1101 to facilitate the limiting and assembly of the roof panel 5.

[0042] Specifically, the slide 1101 and the limiting strip 1102 form a dovetail-shaped guide rail structure, and the roof panel 5 is slidably installed along the inclined surface to prevent longitudinal displacement. One person can complete the installation of the roof panel 5, which improves efficiency and facilitates maintenance and replacement.

[0043] Furthermore, the locking assembly 12 includes a locking tongue 1201, a mounting shell 1202, and a first permanent magnet 1203. The mounting shell 1202 is fixedly installed on the lower surface of the roof panel 5, the locking tongue 1201 is slidably installed inside the mounting shell 1202, and the first permanent magnet 1203 is disposed in the mounting groove of the locking tongue 1201. The first permanent magnet 1203 is magnetically attracted to the second permanent magnet in the locking groove 15.

[0044] Specifically, when the roof panel 5 is pushed into place, the first permanent magnet 1203 and the second permanent magnet attract each other magnetically, causing the locking tongue 1201 to extend and insert into the locking groove 15, forming a mechanical lock and performing lateral locking, thereby improving installation efficiency.

[0045] The method of using this utility model is as follows:

[0046] Align the T-shaped block 14 of the horizontal plate 1 with the first T-shaped groove 8 at the top of the crossbeam 10 and push it into place along the length direction; pre-insert the T-shaped nut 701 into the first T-shaped groove 8 and the second T-shaped groove 13, and align the two corner brackets 9 with the left and right sides of the crossbeam 10 and the horizontal plate 1 respectively; pass the hexagonal socket bolt 702 through the mounting hole of the corner bracket 9 and tighten it with the T-shaped nut 701 to make the corner bracket 9 firmly connected to the crossbeam 10 and the horizontal plate 1;

[0047] Align the limiting strip 1102 of the roof panel 5 with the groove 1101 of the inclined panel 3, so that the roof panel 5 is installed on the upper surface of the inclined panel 3, and ensure that the supporting sponge strip 4 elastically abuts against the lower surface of the roof panel 5.

[0048] Continue pushing the roof panel 5 until the locking component 12 is aligned with the locking groove 15. A "click" sound indicates that the roof panel 5 is locked. This means that the locking tongue 1201 of the locking component 12 extends and inserts into the locking groove 15. Align the locking pin 6 with the pin hole and insert the fixing pin 6. Use a rubber hammer to gently tap the fixing pin 6 into place for re-locking.

[0049] EPDM sealing strips can be embedded between adjacent roof panels 5, and the supporting sponge strip 4 supports the lower surface of the roof panel 5, which can fill the gaps and reduce vibration. The fully modular design allows for simple and quick on-site assembly, improving overall installation efficiency.

[0050] It is worth noting that: dry film lubricant can be pre-coated in the first T-groove 8, the second T-groove 13, and the slide 1101 to reduce insertion resistance. The magnetic locking area is equipped with a dust cover to prevent magnetic items such as mud and sand from entering the locking groove 15 during transportation. When the roof panel 5 needs to be installed, the dust cover can be removed.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
