Description

Technical Field

[0001] This utility model relates to the field of housing construction technology, specifically to a modular integrated container house roof that is easy to assemble and disassemble. Background Technology

[0002] Prefabricated houses use steel structures as their load-bearing structure and can be quickly assembled into complete houses by prefabricating wall and roof materials in a factory. However, there are high transportation costs for modular houses with a span exceeding 3 meters, large transportation and storage spaces, slow on-site assembly of individual components, and labor-intensive and time-consuming processes. In addition, most prefabricated houses are used for temporary construction and rental services, creating an urgent need for larger modular houses with higher integration and reusability.

[0003] A search revealed a Chinese patent (publication number: CN215253462U) that discloses "a modular container roof that is easy to assemble and disassemble, comprising a top frame, wherein two rectangular square tubes are bolted to the inside of the top frame, and four rectangular steel plates are bolted to the rectangular square tubes. An outer frame is installed inside the top frame, and several rectangular square tubes are bolted to the inside of the outer frame. Two rectangular steel plates are bolted to the rectangular square tubes. A color-coated roll is provided on one side of the top frame and installed with the outer frame. The inside of the rectangular steel plates is connected to the inside of the rectangular steel plates by M bolts. The connection between the outer frame and the top frame is achieved by folding and overlapping, and the interlocking parts of the top frame and the outer frame are treated with adhesive."

[0004] However, in the process of implementing the relevant technologies, the aforementioned patents have certain technical defects:

[0005] First, the rectangular steel plate modules of this patent rely on bolt connections. After repeated disassembly and assembly, the bolt holes are prone to wear, leading to loose connections. Moreover, the bolt connections between modules require precise alignment of the holes. If there is a large error in the on-site installation, it may cause the modules to be misaligned, increasing the difficulty of construction.

[0006] Secondly, the outer frame of this patent uses 3mm thick flanged folded parts, which are prone to deformation under long-term loads (such as wind loads and snow loads), affecting the overall stability of the structure. In view of this, this utility model proposes a modular integrated container roof that is easy to assemble and disassemble. Utility Model Content

[0007] This invention proposes a modular integrated container roof that is easy to assemble and disassemble, solving the problem that bolted connections between modules in the prior art are prone to loosening after repeated disassembly and assembly.

[0008] The technical solution of this utility model is as follows: A modular integrated container roof that is easy to assemble and disassemble includes a main frame. Several reinforcing crossbars are fixedly connected to the inner side of the main frame and are equidistantly distributed along the width direction of the main frame. A placement groove is opened on the top surface of the main frame, and a top plate assembly is placed inside the placement groove. A first clamping member for pressing the top plate assembly is fixedly connected to the top of the main frame. Guide rails are fixedly connected to both ends of the bottom surface of the main frame. A bottom plate assembly is arranged between the two guide rails. An assembly groove is opened at one end of the guide rail, and a second clamping member for pressing the bottom plate assembly is arranged inside the assembly groove.

[0009] Preferably, a plurality of flow channels are provided around the top of the main frame, and the bottom wall of the flow channels is an inclined structure.

[0010] Preferably, the top plate assembly and the bottom plate assembly have the same structure, and a polyurethane foam layer is filled between the top plate assembly and the bottom plate assembly.

[0011] Preferably, the top plate assembly includes several steel plates placed in a placement groove, one end of the several steel plates is fixedly connected with a locking strip, and the other end of the several steel plates is provided with a locking groove. Adjacent steel plates are connected by sliding cooperation between corresponding locking strips and locking grooves.

[0012] Preferably, the gap between the steel plate and the inner wall of the placement groove is filled with sealant, and the outer side of the steel plate is coated with a fireproof coating.

[0013] Preferably, the first clamping component includes a mounting plate, both ends of which are fixedly connected to the top wall of the main frame. A plurality of elastic rods are fixedly connected to the inner side of the mounting plate, which are equidistantly distributed along the length of the mounting plate. The bottom ends of the plurality of elastic rods are fixedly connected to the same pressure strip, and the bottom of the pressure strip abuts against the top of the top plate assembly.

[0014] Preferably, the second clamping component includes a mounting plate 2, which is fastened to the assembly groove. A plurality of elastic rods 2 are fixedly connected to the inner side of the mounting plate 2 and are equidistantly distributed along the length direction of the mounting plate 2. One end of each of the elastic rods 2 is fixedly connected to the same pressure strip 2, and the pressure strip 2 abuts against one end of the base plate assembly.

[0015] Preferably, the elastic rod one and the elastic rod two have the same structure. The elastic rod two includes a sleeve, one end of which is slidably connected to a sleeve rod, and the inner side of the sleeve is slidably connected to a slider. One side of the slider is fixedly connected to the sleeve rod. A spring is sleeved on the inner side of the sleeve, one end of which abuts against the slider, and the other end of which abuts against the inner wall of the sleeve.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. By replacing traditional bolt connections with the sliding fit of the clip and the slot, the installation steps are simplified, the dependence on the accuracy of the hole position is reduced, the loosening problem caused by the wear of the bolt hole after repeated disassembly and assembly is effectively solved, and the construction efficiency is significantly improved.

[0018] 2. The top plate assembly and bottom plate assembly are subjected to continuous pressure by using elastic clamping components (elastic rod one and elastic rod two) combined with a spring structure. Even with long-term use or slight deformation of the components, they can remain stable and avoid structural failure due to loosening.

[0019] 3. The main frame is equipped with equidistant reinforcing crossbars, which, together with the guide rail design, enhance the overall compressive and deformation resistance, adapt to external forces such as wind load and snow load, and ensure the long-term stability of the roof of the large-span container house.

[0020] 4. Modular components can be quickly disassembled into compact units, reducing transportation space and facilitating storage and reuse. At the same time, the flexible compression structure reduces maintenance frequency and extends service life. Attached Figure Description

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0032] like Figures 1-8 As shown, this embodiment proposes a modular integrated container roof that is easy to assemble and disassemble, including a main frame 1. Several reinforcing crossbars 12 are fixedly connected to the inner side of the main frame 1 and are distributed at equal intervals along the width direction of the main frame 1. A placement groove 13 is opened on the top surface of the main frame 1, and a top plate assembly 2 is placed inside the placement groove 13. A first clamping member 3 for pressing the top plate assembly 2 is fixedly connected to the top of the main frame 1. Guide rails 15 are fixedly connected to both ends of the bottom surface of the main frame 1. A bottom plate assembly 4 is arranged between the two guide rails 15. An assembly groove 16 is opened at one end of the guide rail 15, and a second clamping member 5 for pressing the bottom plate assembly 4 is arranged inside the assembly groove 16.

[0033] During installation, the top plate assembly 2 is placed directly inside the placement slot 13, and then the top plate assembly 2 is pressed and fixed by the first clamping member 3. The bottom plate assembly 4 is directly inserted between the two guide rails 15, and then the bottom plate assembly 4 is pressed and fixed by the second clamping member 5. Similarly, during disassembly, the bottom plate assembly 4 and the top plate assembly 2 can be disassembled directly by gradually removing the second clamping member 5 and the first clamping member 3. The bottom plate assembly 4 and the top plate assembly 2 of the entire structure can be quickly assembled and disassembled without the need for fixing or disassembling one by one with bolts, which greatly reduces the installation difficulty.

[0034] Furthermore, the reinforcing crossbar 12 installed on the inner side of the main frame 1 can greatly improve the load-bearing capacity of the main frame 1, and the first clamping member 3 at the top of the main frame 1 can further increase the compressive strength of the main frame 1, effectively preventing the main frame 1 from deforming under external force factors (wind load, snow load).

[0035] Furthermore, several guide channels 14 are provided around the top of the main frame 1, and the bottom wall of the guide channels 14 is inclined. The guide channels 14 are used to drain rainwater, avoiding the problem that rainwater accumulates on the top of the top plate assembly 2, causing the top plate assembly 2 to be subjected to increased pressure and deformed.

[0036] Furthermore, the top plate assembly 2 and the bottom plate assembly 4 have the same structure. A polyurethane foam layer is filled between the top plate assembly 2 and the bottom plate assembly 4. The polyurethane foam layer can improve the thermal insulation performance of the roof. The top plate assembly 2 includes several steel plates 21 placed in the placement groove 13. One end of the steel plates 21 is fixedly connected with a clip 22, and the other end of the steel plates 21 is provided with a slot 23. Two adjacent steel plates 21 are connected by sliding cooperation between the corresponding clip 22 and the slot 23.

[0037] The design of the locking strip 22 and the locking groove 23 enables a quick and stable connection between adjacent steel plates 21. The steel plates 21 do not need to be fixed by bolts. They can be positioned and locked in the placement groove 13, which greatly reduces the difficulty of disassembly and assembly. Moreover, the structure is stable during long-term disassembly and assembly and can be used for a long time, which also reduces maintenance costs.

[0038] Furthermore, the gap between the steel plate 21 and the inner wall of the placement groove 13 is filled with sealant, and the outer side of the steel plate 21 is coated with a fire-retardant coating. The sealant can increase the sealing between the steel plate 21 and the main frame 1, and it can be removed by simply cutting and removing the sealant during disassembly, and can be reapplied for the next installation; the fire-retardant coating can improve the fire resistance and high temperature resistance of the steel plate 21, preventing the steel plate 21 from softening due to heat in the event of a fire.

[0039] Furthermore, the first clamping member 3 includes a mounting plate 31, both ends of which are fixedly connected to the top wall of the main frame 1. Several elastic rods 32 are fixedly connected to the inner side of the mounting plate 31, which are equidistantly distributed along the length of the mounting plate 31. The bottom ends of the elastic rods 32 are fixedly connected to the same pressure strip 33, and the bottom of the pressure strip 33 abuts against the top of the top plate assembly 2.

[0040] After the top plate assembly 2 is installed, the mounting plate 31 is fixed to the top wall of the main frame 1. Under the action of the elastic rod 32, the pressure strip 33 applies pressure to the top plate assembly 2 to fix it to the inside of the main frame 1. The elasticity of the elastic rod 32 can dynamically compensate for the pressure of the pressure strip 33, avoiding the problem of the top plate assembly 2 becoming loose due to insufficient pressure of the pressure strip 33 on the top plate assembly 2 under long-term wear.

[0041] Furthermore, the second clamping member 5 includes a mounting plate 51, which is fastened to the mounting groove 16. A plurality of elastic rods 52 are fixedly connected to the inner side of the mounting plate 51, which are equidistantly distributed along the length direction of the mounting plate 51. One end of the plurality of elastic rods 52 is fixedly connected to the same pressure strip 53, which abuts against one end of the base plate assembly 4.

[0042] After the base plate assembly 4 is installed, the mounting plate 2 51 is fixed to the inner wall of the assembly groove 16 by screws 54, so that the pressure strip 2 53 applies pressure to the base plate assembly 4 and fixes the base plate assembly 4 to the bottom of the main frame 1. The elastic characteristics of the elastic rod 2 52 can dynamically compensate for the pressure of the pressure strip 2 53, avoiding the problem of the base plate assembly 4 loosening due to insufficient pressure of the pressure strip 2 53 on the base plate assembly 4 under long-term wear.

[0043] Furthermore, the structure of elastic rod 32 is the same as that of elastic rod 52. Elastic rod 52 includes a sleeve 521, one end of which is slidably connected to a rod 522. A slider 523 is slidably connected to the inner side of the sleeve 521. One side of the slider 523 is fixedly connected to the rod 522. A spring 524 is sleeved inside the sleeve 521. One end of the spring 524 abuts against the slider 523, and the other end of the spring 524 abuts against the inner wall of the sleeve 521. The elastic properties of the spring 524 ensure that elastic rod 52 always applies a pushing force to pressure strip 53, so that the base plate assembly 4 is always under pressure and remains fixed to the main frame 1 after installation.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
