Description

Technical Field

[0001] The present invention relates to the field of prefabricated buildings, and in particular to a quick connection structure for prefabricated buildings. Background Art

[0002] Prefabricated buildings are buildings that shift much of the traditional on-site construction work to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connections. With the development of modern industrial technology, building can now be manufactured in batches and sets, just like machine production. Simply transport the prefabricated building components to the construction site and assemble them.

[0003] A Chinese invention patent, published with the publication number CN221345915U, discloses a prefabricated building structure that facilitates rapid assembly and disassembly. The structure comprises an assembly wall, wherein two adjacent assembly walls are connected by assembly columns. The columns have slots formed on their left and right sides, and the assembly walls are fixedly mounted within the assembly column slots. The assembly column slots are provided with sealing gaskets. The assembly wall and the assembly columns are secured by several sets of fastening devices. By providing these fastening devices, when disassembly is required, a pull plate is pulled to release the block from the slot, facilitating disassembly. This structure is suitable for prefabricated buildings, resolving the cumbersome problem of bolted fastening and disassembly in existing prefabricated buildings. This improves the efficiency of disassembly and facilitates rapid assembly and disassembly.

[0004] During the construction of existing prefabricated building structures, operators need to repeatedly pull the pull plates to ensure that each set of fastening devices can be correctly installed and fixed. A large number of assembly walls and assembly columns need to be connected. If each connection point requires multiple operations of the fastening device, there will be a problem of cumbersome installation steps, which will seriously delay the construction progress. Summary of the Invention

[0010] In some of these embodiments, the four limiting plates respectively fit the outer wall surfaces of both sides of the two card slots.

[0011] In some of these embodiments, the first end of the first spring extends into the assembly frame and is fixedly connected to the inner wall surface of the assembly frame, and the second end is fixedly connected to the outer wall surface of the connecting frame that fits the assembly frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] Referring to Figures 1-4 , an embodiment of the present invention provides a quick connection structure for prefabricated buildings, including an assembled wall 1, a connection mechanism 2 and an adjustment mechanism 3.

[0025] The number of the assembled walls 1 is multiple, and the assembled walls 1 are spliced. Limiting grooves 207 are provided on both sides of the splicing ends of two adjacent assembled walls 1. Limiting grooves 207 are provided on both sides of the splicing ends of the two assembled walls 1, and each limiting groove 207 is arranged along the length direction of the splicing ends of the two assembled walls 1.

[0026] The connection mechanism 2 includes an assembly frame 204, a limiting block 203, a limiting plate 201, a connection frame 202 and a first spring 205.

[0027] Two opposite sides of the assembly frame 204 have two card slots, and two adjacent assembled walls 1 are respectively arranged in the two card slots.

[0028] The limiting block 203 penetrates through both sides of the two card slots and is inserted into the limiting grooves 207 on both sides of the two assembled walls 1. The limiting blocks 203 on the same side of the two card slots are connected into a whole.

[0029] There are four limiting plates 201, and the four limiting plates 201 are respectively arranged outside both sides of the two card slots. Limiting blocks 203 are fixed on one side of the four limiting plates 201 facing the card slots. Among them, a plurality of limiting blocks 203 are fixed on the four limiting plates 201, and each limiting block 203 is arranged along the length direction of the card slot. The four limiting plates 201 are all strip-shaped structures, and the length direction of each limiting plate 201 is the same as the arrangement direction of each limiting block 203. The four limiting plates 201 respectively fit the outer wall surfaces of both sides of the two card slots.

[0030] There are two connection frames 202, and the two connection frames 202 are respectively arranged on both sides of the assembly frame 204. The two connection frames 202 are fixedly connected to the two limiting plates 201 located outside the same side of the two card slots.

[0031] The first end of the first spring 205 is connected to the assembly frame 204, and the second end is connected to the connection frame 202. Among them, the first end of the first spring 205 extends into the assembly frame 204 through a through hole 206 provided on the assembly frame 204 and is fixedly connected to the inner wall surface of the assembly frame 204, and the second end is fixedly connected to the outer wall surface of the connection frame 202 that fits the assembly frame 204.

[0032] By pulling the connecting frame 202 to drive the limiting plate 201 and the limiting block 203 to move, and then using the elastic retraction of the connecting frame 202 to make the limiting block 203 slide into the limiting groove 207, the rapid assembly of the assembled wall 1 and the assembled frame 204 can be realized. This operation method is simple and convenient, without complex tools and cumbersome installation steps, greatly saving construction time and improving the construction efficiency of prefabricated buildings, especially suitable for large-scale construction projects.

[0033] The adjusting mechanism 3 includes a second spring 301, a sliding plate 303, a fixed frame 304, a bidirectional screw 307, a turbine and a worm 305.

[0034] The second spring 301 is movably arranged in two clamping grooves in a direction parallel to the assembled wall 1. The second spring 301 is arranged in a direction parallel to the assembled wall 1 and abuts against the two assembled walls 1.

[0035] There are two sliding plates 303. The two sliding plates 303 are respectively arranged in the two clamping grooves. The two sliding plates 303 are both perpendicular to the two sides of the clamping groove. A second spring 301 is fixed to one side of each of the two sliding plates 303 close to the opening of the clamping groove. A plurality of second springs 301 are fixed to each of the two sliding plates 303, and each second spring 301 is arranged along the length direction of the clamping groove. The two sliding plates 303 are both strip-shaped structures, and the length direction of each sliding plate 303 is the same as the arrangement direction of each second spring 301.

[0036] The fixed frame 304 is fixedly connected inside the assembled frame 204.

[0037] The bidirectional screw 307 includes a central section and two screw sections. The central section is rotatably arranged on the fixed frame 304. The two screw sections are respectively arranged on both sides of the central section. The threads of the two screw sections are arranged in opposite directions. The two screws are respectively perpendicular to the two sliding plates 303, and the two screw sections are respectively threadedly connected to the two sliding plates 303.

[0038] The turbine is coaxially and fixedly connected to the outside of the central section.

[0039] The worm 305 is meshed and connected with the turbine. Both ends of the worm 305 extend out of the assembled frame 204. Knobs 302 are fixedly connected to both ends of the worm 305.

[0040] By rotating the knob 302 to drive the bidirectional screw 307 to drive the sliding plate 303 to move, so that the second spring 301 applies pressure to the side surface of the assembled wall 1 for side limiting. This adjusting mechanism 3 can effectively enhance the stability of the assembled wall 1 in the assembled frame 204 and ensure the firmness of the connection structure. Even when affected by external forces or environmental factors, it can ensure that the connections between the components of the prefabricated building are tight and reliable, improving the overall safety and durability of the building.

[0041] Working principle: First, perform the preparatory actions before inserting the assembled wall 1. The operator holds the connecting frames 202 on both sides of the assembly frame 204 respectively, and then applies an outward pulling force. Since one end of the connecting frame 202 is fixedly connected to the limit plate 201, under the action of the pulling force, the connecting frame 202 will drive the limit plate 201 and the limit block 203 fixedly connected to the limit plate 201 to slide outward of the assembly frame 204. At this time, the first spring 205 will pass through the through hole 206 opened at the corresponding position on the outer surface of the assembly frame 204, and the first spring 205 fixedly connected to the outer surface of the connecting frame 202 will undergo elastic deformation during the stretching process and store elastic potential energy. When the limit plate 201 and the limit block 203 are pulled to a suitable position where the assembled wall 1 can smoothly enter the assembly frame 204, the operator carefully aligns the assembled wall 1 with the assembly frame 204 and inserts the assembled wall 1 smoothly into the interior of the assembly frame 204 along the sliding mating surface between the assembly frame 204 and the assembled wall 1. During the insertion process, it is necessary to pay attention to maintaining the horizontal and vertical states of the assembled wall 1 to ensure its accurate positioning. After the assembled wall 1 is completely inserted into the assembly frame 204, the operator releases the hand holding the connecting frame 202. At this time, the previously stretched first spring 205 begins to release elastic potential energy and generates a contraction force. Under the action of this contraction force, the connecting frame 202 starts to move back, thereby driving the limit plate 201 and the limit block 203 to also slide into the interior of the assembly frame 204. And the outer surface of the assembled wall 1 is pre-opened with a limit groove 207 adapted to the limit block 203. When the limit block 203 moves to a position corresponding to the limit groove 207 as the connecting frame 202 retracts, the limit block 203 will accurately slide into the limit groove 207 under the action of the spring contraction force and the guiding effect of the assembly frame 204. The cooperation between the limit block 203 and the limit groove 207 realizes the preliminary positioning and connection of the assembled wall 1 and the assembly frame 204, completes the key step of rapid assembly, and effectively fixes the assembled wall 1 in the horizontal direction.

[0042] After the preliminary assembly is completed, in order to further enhance the stability of the connection between the assembled wall 1 and the connection mechanism 2, it is necessary to limit the side of the assembled wall 1. The operator rotates the knob 302 on the outer surface of the assembly frame 204, and the rotation of the knob 302 directly drives the worm 305 fixedly connected thereto to rotate synchronously. Since the worm 305 meshes with the worm wheel 306 fixed on the bidirectional screw 307, the rotation of the worm 305 will drive the worm wheel 306 to rotate, and then drive the bidirectional screw 307 to rotate on the inner wall of the fixed frame 304. Since the outer surface of the bidirectional screw 307 is threadedly connected to the two groups of sliding plates 303, and the threads of the bidirectional screw 307 are designed bidirectionally, when the bidirectional screw 307 rotates, it will drive the two groups of sliding plates 303 to move in opposite directions along the outer surface of the fixed frame 304. As the sliding plate 303 moves, multiple groups of second springs 301 fixed on the outer surface of the sliding plate 303 will gradually approach the side of the assembled wall 1. When the second spring 301 contacts the side of the assembled wall 1, as the sliding plate 303 continues to move, the second spring 301 will be compressed and undergo elastic deformation. According to Hooke's law, the compressed second spring 301 will exert a reverse pressure on the side of the assembled wall 1, causing the side of the assembled wall 1 to fit tightly with the adjusting mechanism 3. In this way, the assembled wall 1 is also firmly limited in the side direction, and the entire connection structure is more stable and reliable, and can better withstand various external forces that may occur during building construction and use.

[0043] The rapid connection structure for prefabricated buildings of the present invention has the following beneficial effects:

[0044] 1. By pulling the connection frame 202 to drive the limit plate 201 and the limit block 203 to move, and then using the elastic retraction of the connection frame 202 to make the limit block 203 slide into the limit groove 207, the rapid assembly of the assembled wall 1 and the assembly frame 204 can be realized. This operation method is simple and convenient, without complex tools and cumbersome installation steps, greatly saving construction time and improving the construction efficiency of prefabricated buildings.

[0045] 2. By rotating the knob 302 to drive the bidirectional screw 307 to drive the sliding plate 303 to move, so that the second spring 301 exerts pressure on the side of the assembled wall 1 for side limit. This adjusting mechanism 3 can effectively enhance the stability of the assembled wall 1 in the assembly frame 204 and ensure the firmness of the connection structure. Even when affected by external forces or environmental factors, it can ensure that the connections between the components of the prefabricated building are tightly and reliably connected, improving the overall safety and durability of the building.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
