Description

Technical Field

[0001] The invention relates to the technical field of modular wall panels, and in particular to a construction component for modular buildings. Background Art

[0002] Modular buildings are widely used due to their efficient assembly characteristics. As an innovative construction method, modular buildings disassemble buildings into independent functional modules, complete the whole process of prefabrication production from structural frame to interior decoration and equipment pipelines in the factory, and then quickly assemble them on site in the form of "building blocks". The wall panels in modular buildings are the core components, which adopt the standardized design prefabricated in the factory. By integrating embedded autoclaved aerated concrete (ALC) panels or light steel keel composite panels and other materials, they achieve multiple properties of light weight, high strength, thermal insulation, sound insulation and fire prevention. The wall panel module is tightly connected to the steel structure frame through the independently developed clamping system, which serves as the support system of the main structure to enhance the lateral stability.

[0003] The treatment of wall panel joints is a key link to ensure the airtightness of the structure. Traditional sealing solutions mostly use flat sealing strips, but sealing strips are usually set at the contact position between wall panels to ensure the sealing of the unsealed, but traditional flat sealing strips are often difficult to cope with the challenges of complex working conditions due to their limitations of linear contact. When two wall panels are butt-jointed through conventional sealing strips, the seemingly tight joint actually only relies on the single-line compression deformation of the elastic material to maintain the sealing effect. This design is prone to produce micro gaps when facing thermal expansion and contraction, construction and installation deviations, and stress relaxation caused by long-term pressure on materials, which ultimately leads to the attenuation of key performance such as air tightness and water tightness. For this reason, the birth of serrated sealing technology provides a solution to this problem. Its core lies in the use of bionic design principles to process the contact surface of the sealing strip into a precisely arranged trapezoidal or dovetail tooth structure. When two sealing strips are pressed together, the saw teeth will form a three-dimensional cross bite, and its operating mechanism is similar to the precise interlocking of zipper teeth. Within the displacement range, the saw teeth can automatically compensate for the change in the joint size through elastic deformation, thereby maintaining a continuous and stable sealing interface. However, during the assembly of wall panels, the existing technology relies on manual adjustment of the sealing strip position, which makes it difficult to ensure the straightness of the sealing strip. After installation, wrinkles are prone to occur, resulting in misalignment of the saw teeth, which cannot form effective meshing, resulting in gaps, and the sealing performance needs to be improved. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention proposes a modular building construction component, which can ensure the straightness of the sealing strip during installation, thereby solving the problem of misaligned teeth and poor sealing due to the presence of wrinkles.

[0007] Optionally, two force-applying torsion springs are sleeved on the installation shaft, and one end of each of the two force-applying torsion springs is fixedly connected to a support rod, the support rod extends towards the wall panel and is restricted by the limiting member; the other end of each of the two force-applying torsion springs is fixedly connected to the clamping rod.

[0008] Optionally, the limiting member is a limiting groove, the limiting groove is annular, and the support rod is slidably installed in the limiting groove.

[0009] Optionally, the installation shaft is fixedly connected to a rotating shaft, and the axis of the rotating shaft extends along the width direction of the wall panel; the rotating shaft is rotatably installed on the wall panel, and a limiting component is installed in the wall panel, and the limiting component has a locked state and an unlocked state. When the limiting component is in the unlocked state, the rotating shaft can rotate around its own axis; when the limiting component is in the locked state, the rotation of the rotating shaft is restricted; the rotating shaft is connected to a driving member for driving the rotating shaft to rotate around its own axis when the limiting component is in the unlocked state.

[0010] Optionally, the limiting component includes a limiting block, a limiting hole and an unlocking hole; the limiting block is fixedly connected to one end of the rotating shaft pointing to the wall panel; the vertical cross-section of the limiting block is square; the limiting hole is a square hole; the limiting block is slidably installed in the limiting hole; the unlocking hole is a circular hole, and the diameter of the unlocking hole is greater than the diameter of the circumcircle of the limiting block; the unlocking hole is located on the side of the limiting hole away from the sealing strip; the rotating shaft is horizontally movably installed on the wall panel.

[0011] Optionally, the driving member is a driving torsion spring; one end of the driving torsion spring is fixedly connected to the rotating shaft, and the other end is fixedly connected to the wall panel. In the initial state, the driving torsion spring is in a state of storing energy.

[0012] Optionally, the clamping rod is L-shaped; the driving torsion springs at the corresponding positions of two adjacent wall panels have opposite winding directions, so that when the two corresponding clamping rods rotate a preset angle, they are buckled with each other.

[0015] The beneficial effects of the present invention are as follows: By setting a tensioning structure, a modular building construction member of the present invention makes the sealing strip at the vertical edge of the wall panel in a tensioned state before assembling two adjacent wall panels. The upper and lower two tensioning structures straighten the sealing strip, ensuring its straightness and avoiding wrinkles of the sealing strip, thereby solving the problem of poor sealing caused by the misalignment of two serrated sealing strips and loose fitting during the process of assembling the wall; improving the sealing performance.

[0016] Furthermore, during the process of assembling the wall, the rotating shaft rotates around its own axis under the action of the driving torsion spring, and then drives the force-applying torsion spring to rotate in the rotating groove. During the above process, the sealing strip gradually returns to its natural state. When the two clamping rods at the corresponding positions of two adjacent wall panels abut again, the rotating shaft stops rotating. The upper and lower two clamping rods squeeze the sealing strip towards the middle, making the sealing strip fit more tightly; and because the clamping rod is L-shaped, when the clamping rods at the corresponding positions of two adjacent wall panels rotate and abut again, they are buckled with each other, giving a tensile force to each other, thereby solving the problem of separation and gap at the joint of two adjacent wall panels after installation, which reduces the sealing performance.

[0017] In addition, by dividing the force-bearing holes of the sealing strip into small-diameter half-holes and large-diameter half-holes; when the contact position of the clamping rod with the sealing strip moves from the small-diameter half-hole to the large-diameter half-hole, the squeezing force of the upper and lower force-applying torsion springs on the sealing strip towards the middle increases; when the position where the clamping rod abuts against the sealing strip slides from the small-diameter half-hole into the large-diameter half-hole, the force-applying torsion spring releases elastic force, and the pulling force exerted by the two mutually engaged clamping rods on each other increases, further improving the sealing performance at the joint.

Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 12 shown, a construction component for modular buildings provided by an embodiment of the present invention includes a frame 100, a plurality of wall panels 200, a plurality of sealing strips 300, and a plurality of tensioning structures 400; The frame 100 includes a top frame 110, a bottom frame 120, and a plurality of columns 130; both the top frame 110 and the bottom frame 120 are horizontally arranged and are spaced apart along the vertical direction; the columns 130 extend vertically, the upper end of the column 130 is fixedly connected to the top frame 110, and the lower end is fixedly connected to the bottom frame 120; a slide groove 140 is provided on both the lower surface of the top frame 110 and the upper surface of the bottom frame 120; the slide groove 140 is a T-shaped groove.

[0022] The long side of the wall panel 200 is vertically arranged, and slide blocks 201 are fixedly connected to the upper and lower end faces of the wall panel 200. The slide blocks 201 are T-shaped structures matching the slide grooves 140. The slide blocks 201 at the upper end of the wall panel 200 are slidably installed in the slide grooves 140 of the top frame 110, and the slide blocks 201 at the lower end of the wall panel 200 are slidably installed in the slide grooves 140 of the bottom frame 120. Its upper and lower ends are respectively slidably installed on the top frame 110 and the bottom frame 120, thereby completing modular assembly; installation grooves 210 are provided on both vertical edges of the wall panel 200; a plurality of sealing strips 300 are respectively fixedly installed in the plurality of installation grooves 210. The sealing strips 300 extend vertically, and the projection of the side of the sealing strip 300 away from the wall panel 200 on the horizontal plane is serrated. When the sealing strips 300 of adjacent wall panels 200 are spliced, an interlocking structure is formed. Each sealing strip 300 is installed with two tensioning structures 400. The two tensioning structures 400 are symmetrically installed above and below the sealing strip 300. The upper tensioning structure 400 pushes the sealing strip 300 upward, and the lower tensioning structure 400 pushes the sealing strip 300 downward.

[0023] The tensioning structure 400 includes a force-applying torsion spring 410. Two rotating grooves 220 are formed in the vertical edges of the wall panel 200. The two rotating grooves 220 are respectively located in the upper and lower parts of the wall panel 200. A conical force-receiving hole is formed at the corresponding position of the sealing strip 300, and the small end of the force-receiving hole points to the wall panel 200. An installation shaft 221 is arranged in the rotating groove 220. The installation shaft 221 extends along the thickness direction of the wall panel 200. The force-applying torsion spring 410 is sleeved on the installation shaft 221. The two ends of the force-applying torsion spring 410 are respectively fixedly connected with a support rod 411 and a clamping rod 412. The support rod 411 extends towards the wall panel 200. The clamping rod 412 passes through the force-receiving hole and extends out of the sealing strip 300. The upper clamping rod 412 abuts against the upper surface of the upper force-receiving hole, and the lower clamping rod 412 abuts against the lower surface of the lower force-receiving hole. The wall panel 200 is provided with a limiting member, and the limiting member is a limiting groove 230. The limiting groove 230 is annular. The support rod 411 is inserted into the limiting groove 230. In the initial state, the force-applying torsion spring 410 is in a state of storing energy. The limiting groove 230 is used to limit the rotation of the support rod 411 around the axis of the installation shaft 221, so as to prevent the elastic force released by the force-applying torsion spring 410 from reducing the pushing force of the clamping rod 412 on the sealing strip 300. During assembly, the wall panel 200 is installed by quickly positioning through the slider 201 and the chute 140. The force-applying torsion spring 410 has a tendency to release elastic force, but one end of the support rod 411 is inserted into the limiting groove 230, and the elastic force on this side cannot be released, so that the clamping rod 412 has a tendency to release elastic force. The clamping rod 412 of the upper force-applying torsion spring 410 pushes the sealing strip 300 upward, and the clamping rod 412 of the lower force-applying torsion spring 410 pushes the sealing strip 300 downward, thereby straightening the sealing strip 300 and making the sealing strip 300 in a tensioned state, eliminating the wrinkles of the sealing strip 300. Since the two sealing strips 300 are both in a tensioned state, when the two wall panels 200 approach each other, the serrated structures of the two sealing strips 300 are smoothly meshed with each other. By setting the tensioning structure 400, the present invention solves the problem in the prior art that during the assembly of the modular building wall, due to the misalignment of the two serrated sealing strips 300 between two adjacent wall panels 200, the joint is not tightly fitted, resulting in poor sealing performance at the joint.

[0024] In a further embodiment, two force-applying torsion springs 410 are sleeved on the mounting shaft 221. One end of each of the two force-applying torsion springs 410 is fixedly connected to a support rod 411. The support rod 411 extends towards the wall panel 200 and is restricted by a limiting member. The other end of each of the two force-applying torsion springs 410 is fixedly connected to a clamping rod 412. Symmetrical driving forces are provided through the design of the two force-applying torsion springs 410 to eliminate the offloading problem that may be caused by a single force-applying torsion spring 410.

[0025] In a further embodiment, the mounting shaft 221 is fixedly connected to a rotating shaft 222. The axis of the rotating shaft 222 extends along the width direction of the wall panel 200. The rotating shaft 222 is rotatably mounted on the wall panel 200. A limiting assembly is installed inside the wall panel 200. The limiting assembly has a locked state and an unlocked state. When the limiting assembly is in the unlocked state, the rotating shaft 222 can rotate around its own axis. When the limiting assembly is in the locked state, the rotation of the rotating shaft 222 is restricted. The rotating shaft 222 is connected to a driving member, and the driving member is used to drive the rotating shaft 222 to rotate around its own axis when the limiting assembly is in the unlocked state.

[0026] The limiting assembly includes a limiting block 430, a limiting hole 440, and an unlocking hole 450. The limiting block 430 is fixedly connected to one end of the rotating shaft 222 pointing to the wall panel 200. The vertical cross-section of the limiting block 430 is square. The limiting hole 440 is a square hole. The limiting block 430 is slidably mounted in the limiting hole 440. The unlocking hole 450 is a circular hole, and the diameter of the unlocking hole 450 is larger than the diameter of the circumcircle of the limiting block 430. The unlocking hole 450 is located on the side of the limiting hole 440 away from the sealing strip 300. The rotating shaft 222 is horizontally movably mounted on the wall panel 200. The driving member is a driving torsion spring 420. The driving torsion spring 420 is sleeved outside the rotating shaft 222, and one end of the driving torsion spring 420 is clamped to the rotating shaft 222, and the other end is fixedly clamped to the wall panel 200. In the initial state, the driving torsion spring 420 is in a state of storing energy.

[0027] During construction, as two adjacent wall panels 200 approach each other, the distance between the two clamping rods 412 at corresponding positions gradually decreases until they come into contact with each other. As the two wall panels 200 continue to approach, the two clamping rods 412 exert a horizontal thrust on each other, driving the force-applying torsion spring 410 to move horizontally, and then driving the mounting shaft 221 and the rotating shaft 222 to move horizontally within the wall, gradually moving away from the sealing strip 300. During the above process, the limiting block 430 moves horizontally in the limiting hole 440. When the limiting block 430 disengages from the limiting hole 440 and enters the unlocking hole 450, the limiting component switches from the locked state to the unlocked state. After that, the driving torsion spring 420 releases its elastic force, driving the rotating shaft 222 to rotate around its own axis, and then driving the mounting shaft 221 and the force-applying torsion spring 410 to rotate in the rotating groove 220. The clamping rod 412 rotates in the force-receiving hole. The position where the upper clamping rod 412 contacts the sealing strip 300 gradually moves downward, and the position where the lower clamping rod 412 contacts the sealing strip 300 gradually moves upward. During the process of the driving torsion spring 420 driving the rotating shaft 222 to rotate, the sealing strip 300 gradually returns to its natural state. After the rotating shaft 222 rotates a preset angle, the upper and lower clamping rods 412 come into contact with each other again, and the driving torsion spring 420 cannot continue to release its elastic force. At this time, the upper and lower clamping rods 412 squeeze the sealing strip 300 towards the middle, so that the two sealing strips 300 between two adjacent wall panels 200 fit more tightly, further improving the sealing performance.

[0028] In a further embodiment, the clamping rod 412 is L-shaped; the driving torsion springs 420 at corresponding positions of two adjacent wall panels 200 have opposite winding directions, so that when the corresponding two clamping rods 412 rotate a preset angle, they are buckled with each other.

[0029] During assembly, after the L-shaped clamping rod 412 rotates a preset angle along with the rotating shaft 222, the bent portions of the two clamping rods 412 at corresponding positions of two adjacent wall panels 200 are hooked with each other, referring to Figure 10 , to form a mechanical interlocking structure. When the two wall panels 200 tend to move away from each other, the two clamping rods 412 are tightened with each other, thereby preventing the separation of the joint positions of the two wall panels 200 and reducing the sealing performance.

[0030] In a further embodiment, the force-receiving hole includes a small-diameter half-hole 310 and a large-diameter half-hole 320; the diameter of the large-diameter half-hole 320 is larger than that of the small-diameter half-hole 310; in the force-receiving hole located above, the small-diameter half-hole 310 is located above the large-diameter half-hole 320; in the force-receiving hole located below, the large-diameter half-hole 320 is located above the small-diameter half-hole 310.

[0031] During the process of two adjacent wall panels 200 approaching each other, the two latch rods 412 at corresponding positions abut against each other and exert a thrust on each other, so that the limit block 430 disengages from the limit hole 440 and enters the unlocking hole 450, driving the torsion spring 420 to drive the rotating shaft 222 to rotate. During the process of the rotating shaft 222 rotating around itself, the latch rod 412 rotates synchronously with it. When the two latch rods 412 abut against each other, the rotating shaft 222 stops rotating. During the above process, the position where the latch rod 412 abuts against the sealing strip 300 slides from the small-diameter semi-hole 310 into the large-diameter semi-hole 320, the biasing torsion spring 410 releases elastic force, the included angle between the latch rod 412 and the support rod 411 becomes smaller, and the pulling force exerted by the two mutually engaged latch rods 412 on each other increases, further improving the sealing performance at the joint.

[0032] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
