Description

Technical Field

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

[0002] Modular construction is widely used due to its efficient assembly. As an innovative construction method, modular construction breaks down buildings into independent functional modules, prefabricating everything from the structural frame to interior finishes and equipment and pipelines in a factory. These modules are then rapidly assembled on-site like "building blocks." The wall panels in modular buildings serve as core components, utilizing a standardized, factory-prefabricated design. By integrating embedded autoclaved aerated concrete (ALC) panels or lightweight steel-frame composite panels, they achieve multiple properties: lightweight, high strength, thermal insulation, sound insulation, and fire resistance. The wall panels are tightly connected to the steel structure frame using a proprietary clamping system, serving as the main structural support and enhancing lateral stability.

[0003] Treating wall panel joints is crucial for ensuring structural airtightness. Traditional sealing solutions often utilize flat sealing strips, but sealing strips are typically installed at the contact points between wall panels to ensure tightness. However, due to the limitations of linear contact, traditional flat sealing strips often struggle to meet the challenges of complex working conditions. When two wall panels are butted together using conventional sealing strips, the seemingly tight joint actually relies solely on the single-line compression deformation of the elastic material to maintain its sealing effect. This design is prone to microgaps due to thermal expansion and contraction, construction and installation deviations, and stress relaxation caused by long-term material pressure, ultimately leading to a degradation of key performance properties such as airtightness and watertightness. Serrated sealing technology has been developed to address this problem. Its core lies in employing biomimetic design principles to machine the contact surface of the sealing strip into a precisely arranged trapezoidal or dovetail-shaped tooth structure. When two sealing strips are pressed together, the serrations form a three-dimensional cross-interlocking mechanism, similar to the precise interlocking of zipper teeth. Within their displacement range, the serrations automatically compensate for variations in the joint dimensions through elastic deformation, maintaining a continuous and stable seal. However, during wall panel assembly, existing technology relies on manual adjustment of the sealing strip position, making it difficult to ensure its straightness. After installation, wrinkles can easily form, leading to misalignment of the serrations, preventing effective engagement and creating gaps. This leaves room for improvement in sealing performance. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, 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.

[0011] Optionally, two force-applying torsion springs are sleeved on the mounting shaft, one end of each of the force-applying torsion springs is fixedly connected to a support rod, the support rod extends toward the wall panel and is restricted by a limiting member; the other ends of the two force-applying torsion springs are fixedly connected to the clamping rod.

[0012] Optionally, the limiting member is a limiting groove, the limiting groove is annular, and the support rod is slidably installed in the limiting groove.

[0013] Optionally, the mounting 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 mounted on the wall panel, and a limiting assembly is installed in the wall panel, and the limiting assembly has a locked state and an unlocked state. When the limiting assembly is in the unlocked state, the rotating shaft can rotate around its own axis; when the limiting assembly is in the locked state, the rotation of the rotating shaft is restricted; the rotating shaft is connected to a driving member, and the driving member is used to drive the rotating shaft to rotate around its own axis when the limiting assembly is in the unlocked state.

[0014] Optionally, the limiting assembly includes a limiting block, a limiting hole and an unlocking hole; the limiting block is fixedly connected to the 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 larger than the diameter of the circumscribed circle 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 installed on the wall panel for horizontal movement.

[0015] 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 force storage state.

[0016] Optionally, the clamping rod is L-shaped; the driving torsion springs at corresponding positions of two adjacent wall panels rotate in opposite directions, so that the corresponding two clamping rods engage with each other when they rotate to a preset angle.

[0017] Optionally, the stress-bearing hole includes a small-diameter half hole and a large-diameter half hole; the diameter of the large-diameter half hole is larger than the diameter of the small-diameter half hole; in the stress-bearing hole located above, the small-diameter half hole is located above the large-diameter half hole; in the stress-bearing hole located below, the large-diameter half hole is located above the small-diameter half hole.

[0019] The beneficial effects of the present invention are as follows: a modular building construction component of the present invention is provided with a tensioning structure, so that the sealing strips at the vertical edges of the wall panels are in a tensioned state before two adjacent wall panels are assembled. The upper and lower tensioning structures straighten the sealing strips to ensure their straightness and avoid wrinkles on the sealing strips, thereby solving the problem of poor sealing due to misalignment of the teeth of the two serrated sealing strips and loose fit during the wall assembly process; and improving the sealing performance.

[0020] Furthermore, during the process of assembling the wall, the rotating shaft rotates around its own axis under the action of the driving torsion spring, thereby driving 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 the two adjacent wall panels abut against each other again, the rotating shaft stops rotating, and the upper and lower clamping rods squeeze the sealing strip toward the middle, making the sealing strip fit more tightly; and because the clamping rods are L-shaped, when the clamping rods at the corresponding positions of the two adjacent wall panels rotate and abut against each other again, the two are interlocked and apply tension to each other, thereby solving the problem of gaps forming at the joints of the two adjacent wall panels after installation, thereby reducing the sealing performance.

[0021] In addition, by dividing the force-bearing hole of the sealing strip into a small-diameter half hole and a large-diameter half hole; when the contact position of the clamping rod and 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 toward the middle increases; when the contact position of the clamping rod and the sealing strip slides from the small-diameter half hole to the large-diameter half hole, the force-applying torsion spring releases the elastic force, and the two clamping rods that are interlocked with each other increase the pulling force applied to each other, thereby further improving the sealing of the joint.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] like Figures 1 to 12 As shown, a modular building construction component 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;

[0042] The frame 100 includes a top frame 110, a bottom frame 120 and a plurality of columns 130; the top frame 110 and the bottom frame 120 are both arranged horizontally and spaced apart in the vertical direction; the columns 130 extend vertically, the upper ends of the columns 130 are fixedly connected to the top frame 110, and the lower ends are fixedly connected to the bottom frame 120; a slide groove 140 is provided on 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.

[0043] The long side of the wall panel 200 is arranged vertically, and the upper and lower end surfaces of the wall panel 200 are fixedly connected with a slider 201. The slider 201 is a T-shaped structure that matches the slide groove 140. The slider 201 at the upper end of the wall panel 200 is slidably installed in the slide groove 140 of the top frame 110, and the slider 201 at the lower end of the wall panel 200 is slidably installed in the slide groove 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; the two vertical edges of the wall panel 200 are provided with mounting grooves 210; multiple sealing strips 300 are respectively fixedly installed in multiple mounting grooves 210, and the sealing strips 300 extend vertically. The projection of the side of the sealing strip 300 away from the wall panel 200 in the horizontal plane is serrated. The sealing strips 300 of adjacent wall panels 200 form a staggered meshing structure when spliced;

[0044] Each sealing strip 300 is installed with two tensioning structures 400 , which are symmetrically installed on the sealing strip 300 up and down. The tensioning structure 400 located on the top pushes the sealing strip 300 upward, and the tensioning structure 400 located on the bottom pushes the sealing strip 300 downward.

[0045] The tensioning structure 400 includes a force-applying torsion spring 410; two rotation grooves 220 are provided on the vertical edge of the wall panel 200, and the two rotation grooves 220 are respectively located at the upper and lower parts of the wall panel 200; a conical force-bearing hole is provided at the corresponding position of the sealing strip 300, and the small end of the force-bearing hole points to the wall panel 200; a mounting shaft 221 is provided in the rotation groove 220, and the mounting shaft 221 extends along the thickness direction of the wall panel 200, and the force-applying torsion spring 410 is sleeved on the mounting shaft 221; the two ends of the force-applying torsion spring 410 are respectively fixedly connected to a support rod 411 and a clamping rod 412, the support rod 411 extends toward the wall panel 200, and the clamping rod 412 extends toward the wall panel 200. 12 passes through the force-bearing hole and extends out of the sealing strip 300; the upper clamping rod 412 abuts against the upper surface of the upper force-bearing hole, and the lower clamping rod 412 abuts against the lower surface of the lower force-bearing hole; the wall panel 200 is provided with a limiting member, which is a limiting groove 230. The limiting groove 230 is annular, and the support rod 411 is inserted into the limiting groove 230; in the initial state, the force-applying torsion spring 410 is in a force-storing state; the limiting groove 230 is used to limit the support rod 411 from rotating around the axis of the installation shaft 221, thereby preventing the force-applying torsion spring 410 from releasing its elastic force, thereby reducing the pushing force of the clamping rod 412 on the sealing strip 300;

[0046] During assembly, the wall panel 200 is quickly positioned and installed through the slider 201 and the slide groove 140. The force-applying torsion spring 410 tends to release the 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 tends to release the elastic force. The clamping rod 412 of the force-applying torsion spring 410 at the top pushes the sealing strip 300 upward, and the clamping rod 412 of the force-applying torsion spring 410 at the bottom pushes the sealing strip 300 downward, thereby straightening the sealing strip 300 and making the sealing strip 300 The sealing strips 300 are in a tensioned state, eliminating wrinkles on the sealing strips 300. Since both sealing strips 300 are in a tensioned state, when the two wall panels 200 are close to each other, the serrated structures of the two sealing strips 300 are smoothly interlaced and meshed. By providing a tensioning structure 400, the present invention solves the problem of poor sealing at the joints of modular buildings in the prior art during the process of assembling walls, due to the misaligned teeth of the two serrated sealing strips 300 between two adjacent wall panels 200, which are not tightly fitted.

[0047] In a further embodiment, two force-applying torsion springs 410 are sleeved on the mounting shaft 221, and one end of the two force-applying torsion springs 410 is fixedly connected to a support rod 411, which extends toward the wall panel 200 and is restricted by a limiting member; the other ends of the two force-applying torsion springs 410 are fixedly connected to a clamping rod 412; the design of the two force-applying torsion springs 410 provides a symmetrical driving force, thereby eliminating the overload problem that may be caused by a single force-applying torsion spring 410.

[0048] In a further embodiment, the mounting shaft 221 is fixedly connected to a rotating shaft 222, and 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, and a limiting assembly is installed in the wall panel 200, and 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.

[0049] 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 the end of the rotating shaft 222 pointing toward the wall panel 200. The limiting block 430 has a square vertical cross-section. 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 its diameter is larger than the diameter of the circumscribed circle 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 on the exterior of the rotating shaft 222, with one end of the driving torsion spring 420 clamped to the rotating shaft 222 and the other end fixedly clamped to the wall panel 200. In the initial state, the driving torsion spring 420 is in a charged state.

[0050] 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 abut against each other; as the two wall panels 200 continue to approach each other, the two clamping rods 412 give each other a horizontal thrust, driving the force-applying torsion spring 410 to move horizontally, thereby driving the installation shaft 221 and the rotating shaft 222 to move horizontally in the wall, gradually away from the sealing strip 300. In the above process, the limit block 430 moves horizontally in the limit hole 440. When the limit block 430 disengages from the limit hole 440 and enters the unlocking hole 450, the limit assembly switches from the locked state to the unlocked state. Thereafter, the torsion spring 420 is driven to release the elastic force, driving the rotating shaft 222 to rotate around its own axis, thereby The installation shaft 221 and the force torsion spring 410 are driven to rotate in the rotation groove 220, and the clamping rod 412 is rotated in the force hole. The contact position of the upper clamping rod 412 and the sealing strip 300 gradually moves downward, and the contact position of the lower clamping rod 412 and the sealing strip 300 gradually moves upward. In the process of driving the torsion spring 420 to drive the rotating shaft 222 to rotate, the sealing strip 300 gradually returns to its natural state. After the rotating shaft 222 rotates by a preset angle, the upper and lower clamping rods 412 abut against each other again, and the driving torsion spring 420 can no longer release the elastic force. At this time, the upper and lower clamping rods 412 squeeze the sealing strip 300 toward the middle, so that the two sealing strips 300 between the two adjacent wall panels 200 fit more tightly, further improving the sealing performance.

[0051] 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 rotate in opposite directions, so that the corresponding two clamping rods 412 engage with each other when they rotate to a preset angle.

[0052] During assembly, after the L-shaped clamping rod 412 rotates with the rotating shaft 222 at a preset angle, the bent portions of the two clamping rods 412 at corresponding positions of two adjacent wall panels 200 are hooked with each other. Figure 10, forming a mechanical interlocking structure. When the two wall panels 200 tend to move away from each other, the two clamping rods 412 pull each other tight, thereby preventing the joints of the two wall panels 200 from separating and reducing the sealing performance.

[0053] In a further embodiment, the stress-bearing 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 the diameter of the small-diameter half hole 310; in the upper stress-bearing hole, the small-diameter half hole 310 is located above the large-diameter half hole 320; in the lower stress-bearing hole, the large-diameter half hole 320 is located above the small-diameter half hole 310.

[0054] As two adjacent wall panels 200 approach each other, the two corresponding latching rods 412 abut against each other and exert a force on each other, causing the stop block 430 to disengage from the stop hole 440 and enter the unlocking hole 450, driving the torsion spring 420 to rotate the rotating shaft 222. As the rotating shaft 222 rotates, the latching rod 412 rotates synchronously with it until the two latching rods 412 abut against each other, at which point the rotating shaft 222 stops rotating. During this process, the location where the latching rod 412 abuts the sealing strip 300 slides from the smaller half-hole 310 into the larger half-hole 320, releasing the force of the torsion spring 410. The angle between the latching rod 412 and the support rod 411 decreases, and the tension exerted by the two latching rods 412 on each other increases, further improving the sealing of the joint.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
