Description

Technical Field

[0001] The present invention belongs to the technical field of modular buildings, and in particular relates to a modular building and an assembly method thereof. Background Art

[0002] Modular construction involves breaking a building down into a series of standardized modules, which can be designed, processed, and assembled in a factory and then transported to the construction site for rapid assembly. Because most construction work is completed in the factory, modular construction enables higher quality control and engineering efficiency, reducing human error and construction time. The on-site construction workload of modular buildings is greatly reduced, so the noise and dust generated during construction are also reduced, resulting in less impact on the environment.

[0003] Problems with existing technologies:

[0004] Large space volume: Although the main frame of some modular houses is processed in the factory, due to its large space, the number of main frames transported at one time is too small, which requires more manpower and financial resources to transport the frames;

[0005] The fixed construction is cumbersome: When splicing the modular houses, a full-scale splicing work needs to be carried out between each two separate buildings, which makes the splicing work too cumbersome and seriously time-consuming and labor-intensive;

[0006] Poor sound insulation: Modular houses are commonly used to build temporary construction site dormitories, temporary convenience stores, temporary hospitals, etc. Compared with traditional concrete buildings, these buildings generally have poor sound insulation, and the vibration transmission effect of the structure with steel frame as the main body is very obvious.

[0025] Step 2: Assemble the main structure. Open the wall windows on both sides of the central frame and pull out four side wall panels.

[0027] Step 4: Connect and fix the buildings on each floor. Assemble the four bottom support pipes to the bottom ends of the four square steel columns of the lowest building. Use a crane to complete the stacking of the multi-story buildings and ensure that the square steel columns are aligned and plugged in. Assemble the four top cover pipes to the top ends of the square steel columns of the top building. Finally, tighten the nuts and pull through the second block. The anchor heads in each square steel column will be hooked and pulled upward. At this point, the fixing work of the buildings on each floor is completed.

[0028] Step 5: Interior decoration, lay the interior panels on all the inner walls of the building and seal the gaps, then arrange the electrical wires and water pipes, install doors and windows, etc.

[0029] The technical effects achieved by the present invention are:

[0030] According to the present invention, after the modular wall assembly is disassembled, deformed and stored, its volume is only about one-third of the volume of the finished building. After storage, the floor space is greatly saved, and multiple modular wall assemblies are conveniently transported at one time, thereby greatly improving the efficiency of transportation work.

[0031] The present invention, with the help of the vertical connection assembly, makes the square steel columns, top cover tubes and bottom support tubes located in the same vertical direction be under the same fixed stress, so that the multiple square steel columns that are plugged in are firmly fixed. In this way, the fixing work of the building on each floor can be completed, and when it is necessary to dismantle a multi-story building, it is only necessary to remove the top cover tube at the top to easily complete the dismantling work of the multiple square steel columns.

[0032] The present invention has a negative pressure cover that is in contact with the lower surface of the central frame, and its interior is in a negative pressure state. By virtue of the characteristic of the negative pressure state that can hinder the propagation of sound, it can play an effect of hindering the propagation of sound between the upper and lower floors of the building, thereby optimizing the sound insulation effect of the modular building. In addition, the spring, the soft pad and the ring pad can simultaneously play a vibration reduction effect, thereby hindering the process of vibration sound transmission.

[0033] According to the present invention, when the negative pressure hood moves up to a specified position, the negative pressure tube automatically stops pumping air into the negative pressure hood, and when the negative pressure hood slides down to the specified position due to gas infiltration, the negative pressure tube automatically resumes pumping air into the negative pressure hood, thereby ensuring the sound insulation effect of the negative pressure hood.

[0034] The present invention uses an assisting member to provide external force to rotate and fold the bottom wall panels, thereby solving the problem that it is inconvenient for workers to apply force from the bottom of the house, promoting the rotation and folding of the bottom wall panels, and facilitating the combination, deformation and storage of the modular wall.

[0059] Example 1:

[0060] Refer to the attached Figure 1-Figure 3The top plate 101 is fixedly installed on the inner wall of the top of the middle frame 2, and the two top wall panels 102 are hinged on both sides of the top plate 101 respectively. Square steel 112 is integrally provided on both sides of the two top wall panels 102 away from the hinge. The four bottom wall panels 107 are folded and rotated and assembled in sequence, and the two bottom wall panels 107 at both ends are rotated and assembled with the bottom ends of the corresponding end wall panels 103 at the same time. The adjacent bottom wall panels 107 and the end wall panels 103 and the bottom wall panels 107 are rotated and assembled through adapters 108.

[0061] Refer to the attached Figure 1-Figure 3 When the two end wall panels 103 and the four bottom wall panels 107 are unfolded at the same time, the end wall panel 103 is located at the end of the top wall panel 102 and the square steel column 105 is aligned with the corresponding square steel 112. The eight side wall panels 109 are respectively assembled in an array at the two ends of the corresponding bottom wall panel 107, and the bottom wall panel 107 and its adjacent wall panels are connected by fixings at the same time. The inner wall of the unfolded single building house is paved with interior panels 110 for decoration and sealing. One of the end wall panels 103 is penetrated by a door and window 104, and the other end wall panel 103 is penetrated by a pipeline hole 106.

[0062] Refer to the attached Figure 3-Figure 4 、 Figure 9 The outer walls of the two top wall panels 102 near one end of the hinge are fixed with an arc-shaped guide frame 111, and the inner walls on both sides of the middle frame 2 are fixed with guide columns 202, and the guide columns 202 can move through the corresponding arc-shaped guide frames 111.

Then, a crane is used to complete the stacking of the multi-story building house, and ensure that each square steel column 105 is aligned and plugged. When the upper and lower square steel columns 105 are aligned and connected, the inner steel 114 located on the upper side penetrates the corresponding square steel 112 and is inserted into the top of the lower square steel column 105, and the four top cover pipes 305 are assembled. Assembled at the top of the square steel column 105 of the top building, the second inner piercing steel 306 penetrates the corresponding square steel 112 and is inserted into the top of the square steel column 105 below. During the above process, the anchor head 302 will contact the corresponding anchor hook 1 304 or anchor hook 2 309. Finally, the nut 313 is tightened and the piercing block 2 308 is pulled up.

The inner side of the bowl tube body 401 is sealed and lifted and slidably assembled with a negative pressure cover 404, and an air port 405 is opened at the most concave point of the center of the negative pressure cover 404. A negative pressure pipe 406 is connected to the bottom of the negative pressure cover 404 and at the position corresponding to the air port 405. The negative pressure pipe 406 passes through the bowl tube body 401, and a top rod 407 is fixedly connected to the bottom of the negative pressure cover 404 and on one side of the negative pressure pipe 406. The top rod 407 passes through the bowl tube body 401.

[0073] Refer to the attached Figures 9-12, an air valve 408 is fixedly installed on one side of the center of the bottom circle of the bowl tube body 401, and both sides of the air valve 408 are rotatably assembled on the gear 409, and the gear 409 is fixedly connected to the valve core inside the air valve 408, and a rotating core frame 410 is fixedly installed on the bottom of the bowl tube body 401 and on one side of the air valve 408, and a pry bar 411 is rotatably assembled on the bottom end of the rotating core frame 410, one end of the pry bar 411 is connected to the bottom end of the top rod 407, and the other end of the pry bar 411 is integrally provided with a gear rod 412 for meshing with the gear 409, the end of the negative pressure tube 406 is connected to one of the interfaces of the air valve 408, and an annular air pipe 413 is fixedly provided at the bottom of the bowl tube body 401, and the annular air pipe 413 is connected to another interface of the air valve 408, and the top of the air valve 408 is connected to an air supply pipe.

[0074] Refer to the attached Figures 9-12 The outer wall of the edge of the bowl tube body 401 is assembled with an injection pipe 415 in an array-like rotation manner, and the end of the injection pipe 415 is assembled with a piston 416 in a telescopic manner. The end of the piston 416 is rotatably installed on the bottom surface of the support moat body 204. The surface of the piston 416 located on the outer part of the injection pipe 415 is provided with a spring 2 417. The outer wall of the injection pipe 415 near one end of the bowl tube body 401 is respectively connected to the intake pipe 418 and the outlet pipe 419, and the ends of the intake pipe 418 are connected to the annular air pipe 413. The intake pipe 418 and the outlet pipe 419 are both installed with a one-way valve.

[0075] According to the above structure, when the upper structure is deformed due to the activities of the people inside, the deformation of the middle frame 2 in the middle is more obvious than that at the edge. At this time, the bowl tube body 401 fitted with it will undergo a slight displacement, and the spring 1 402 will deform accordingly. The air injection pipe 415 and the piston 416 at the edge of the bowl tube body 401 will also undergo telescopic movement. The spring 2 417 will also deform. The gas inside the air injection pipe 415 will be squeezed out through the air outlet pipe 419, and then the air will be sucked in through the air intake pipe 418. This suction force acts on the negative pressure cover 404 at the same time through the negative pressure pipe 406. 14 is fitted with the lower surface of the middle frame 2 to form a closed space. When the air inside the top of the negative pressure cover 404 is gradually reduced, the negative pressure cover 404 will gradually slide upward until it is stably fitted with the lower surface of the middle frame 2. In the above process, the negative pressure cover 404, which is fitted with the lower surface of the middle frame 2, is in a negative pressure state. By virtue of the characteristic that the negative pressure state can hinder the propagation of sound, it can play an effect of hindering the propagation of sound between the upper and lower floors of the building, thereby optimizing the sound insulation effect of the modular building. In addition, the spring 1 402, the soft pad 205 and the ring pad 414 can also play a vibration reduction effect, thereby hindering the process of vibration sound transmission.

[0076] When the negative pressure cover 404 moves upward, the push rod 407 can pull the pry bar 411 to rotate, and the gear rod 412 at the other end of the pry bar 411 will mesh with the gear 409, causing the valve core in the air valve 408 to rotate. When the negative pressure cover 404 moves upward to the limit position, the air valve 408 will close the connection between the negative pressure pipe 406 and the ring air pipe 413, and the ring air pipe 413 will be connected to the air supply pipe. At this time, the negative pressure in the negative pressure cover 404 is maintained; when the negative pressure cover 404 penetrates into the interior of the negative pressure cover 404 and moves downward, during the downward movement, The push rod 407 will cause the pry bar 411 to reverse, and finally the valve core in the air valve 408 will reverse, and the negative pressure tube 406 and the ring air tube 413 will be restored to the connection state, and the air injection tube 415 will resume the work of extracting the air inside the negative pressure cover 404. In the above process, the negative pressure cover 404 can automatically stop the negative pressure tube 406 from pumping air inside it when it moves up to the specified position, and when the negative pressure cover 404 slides down to the specified position due to gas infiltration, the negative pressure tube 406 can automatically resume the pumping work of the negative pressure cover 404, thereby ensuring the sound insulation effect of the negative pressure cover 404.

[0077] The working principle of the present invention is as follows: when multi-story buildings are stacked, the support trench body 204 on the top of a middle frame 2 will fit in with the lower surface of the middle frame 2 above it, and the soft pad 205 on the surface of the support trench body 204 will also have the effect of sound absorption and vibration reduction, and the sound insulation part 4 installed inside each support trench body 204, among which the bowl tube body 401 will fit in with the lower surface of the upper middle frame 2 under the elastic support of the spring 1 402, and the ring pad 414 on the top edge of the bowl tube body 401 and the spring 1 402 also have the effect of sound absorption and vibration reduction. When the upper building is deformed due to the activities of the people inside, the deformation degree of the middle frame 2 in the middle is more obvious than that at the edge. The bowl tube body 401 that fits thereto will undergo a slight displacement, and the spring 1 402 will be deformed accordingly. The air injection tube 415 and the piston 416 at the edge of the bowl tube body 401 will also undergo telescopic movement, and the spring 2 417 will also be deformed. The gas inside the air injection tube 415 will be squeezed out through the air outlet pipe 419, and then the air will be sucked in through the air intake pipe 418. This suction force will act on the negative pressure cover 404 at the same time through the negative pressure pipe 406. Since the ring gasket 414 fits with the lower surface of the middle frame 2 to form a closed space, when the air inside the top of the negative pressure cover 404 gradually decreases, the negative pressure cover 404 will gradually slide upward until it stably fits with the lower surface of the middle frame 2.

[0078] When the negative pressure cover 404 moves upward, the push rod 407 can pull the pry rod 411 to rotate, and the gear rod 412 at the other end of the pry rod 411 will mesh with the gear 409, causing the valve core in the air valve 408 to rotate. When the negative pressure cover 404 moves upward to the limit position, the air valve 408 will close the connection between the negative pressure pipe 406 and the annular air pipe 413, and the annular air pipe 413 will be connected to the air supply pipe. At this time, the negative pressure in the negative pressure cover 404 is maintained; when the negative pressure cover 404 infiltrates into the inside of the negative pressure cover 404 and slides downward, during the downward movement, the push rod 407 will pull the pry rod 411 to reverse, and finally the valve core in the air valve 408 will reverse, the negative pressure pipe 406 and the annular air pipe 413 will be restored to the connection state, and the air injection pipe 415 will resume the work of extracting air from the inside of the negative pressure cover 404.

[0079] Example 4:

[0080] Refer to the attached Figure 13-14 , both sides of the middle part of the bottom of the middle frame 2 are symmetrically provided with storage grooves 203, and one end of each storage groove 203 is provided with a through-hole 206, the power assist member 5 includes a slot frame 501 rotatably installed inside the corresponding storage groove 203, and the two adjacent slot frames 501 are symmetrically arranged, the outer wall of the end of the slot frame 501 is integrally provided with a coil spring shell 502, and the slot frame 501 is assembled with a knock rod 503 through the elastic rotation of the coil spring shell 502 inside the coil spring shell 502, the outer wall of the slot frame 501 at the transfer point is integrally provided with an extension plate 504, and both sides of the middle part of the bottom of the middle frame 2 are slidably assembled with push blocks 505, the push blocks 505 are used to squeeze the extension plate 504, and a spring three 506 is connected between its inner wall and the inner wall of the middle frame 2.

[0081] According to the above structure, when dismantling the building, in order to facilitate the rotation and folding of the bottom wall panels 107 at the bottom, the staff only needs to use a long rod to push the push block 505, and the push block 505 moves toward the inner side of the bottom of the middle frame 2 and squeezes the spring 3 506. The push block 505 will also squeeze the extension plate 504 and cause the slot frame 501 to rotate. When the slot frame 501 rotates to the position of the through-hole 206, one end of the knock rod 503 will suddenly lose its obstruction, and the knock rod 503 will be in the coil spring housing 5 02 rotates rapidly under the action of the internal coil spring. At this time, one end of the knock rod 503 will quickly pass through the through-hole 206, and the other end of the knock rod 503 will hit the junction of two bottom wall panels 107, causing the two bottom wall panels 107 to rotate in opposite directions. In this way, with the help of the assisting member 5, an external force is provided to rotate and fold the bottom wall panels 107, which solves the problem that it is inconvenient for the staff to apply force from the bottom of the house, promotes the rotation and folding of the bottom wall panels 107, and facilitates the deformation and storage of the modular wall combination 1.

[0082] The working principle of the present invention is as follows: the staff uses a long rod to push the push block 505, and the push block 505 moves toward the inner side of the bottom of the middle frame 2 and squeezes the spring three 506. The push block 505 will also be squeezed with the extension plate 504 and cause the slot frame 501 to rotate. When the slot frame 501 rotates to the position of the through-opening 206, one end of the knocking rod 503 will suddenly lose its obstruction, and the knocking rod 503 will rotate rapidly under the action of the coil spring inside the coil spring shell 502. At this time, one end of the knocking rod 503 will quickly pass through the through-opening 206, and the other end of the knocking rod 503 will hit the junction of two bottom wall panels 107, causing the two bottom wall panels 107 to rotate in opposite directions, making it convenient for the bottom wall panels 107 to rotate and fold.

At the same time, align the square steel 112 at the end of the top wall panel 102 with the top of the corresponding square steel column 105. Then, assemble the eight side wall panels 109 on both sides of the building. Repeat this operation to complete the assembly of the main structure of multiple buildings.
