Description

Technical Field

[0001] This utility model relates to the field of prefabricated housing technology, specifically a new type of composite wall panel for low-rise prefabricated steel structure housing. Background Technology

[0002] Steel-structured housing refers to dwellings whose main structure is made of shaped steel or steel plates. The various structural elements are connected by riveting, welding, or bolting. The walls of steel-structured housing typically use composite wall panels to shorten construction time.

[0003] Currently, composite wall panels generally use hollow core panels filled with thermal insulation material. Adjacent panels are typically joined using a snap-fit ​​method, with the joints filled with a waterproofing material, usually foam. In practice, the snap-fit ​​structure only provides temporary fixation and doesn't prevent lateral movement. Furthermore, the joint width varies depending on the installation process and the expansion of the waterproofing material. Additionally, gaps are left between the top surface and the bottom surface of the roof during installation. These gaps are usually filled with cement mortar or foam, which is difficult to remove later, hindering the reuse of the panels. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a new type of composite wall panel for low-rise prefabricated steel structure residential buildings.

[0005] The technical solution of this utility model is:

[0006] A novel composite wall panel for low-rise prefabricated steel structure residential buildings, comprising:

[0008] A connector, comprising a first screw and a tensioning structure, wherein the first screw and the tensioning structure are engaged to tension two adjacent wall panels in the horizontal direction;

[0009] Fasteners are used to secure the wall panel to the main steel structure.

[0010] Preferably, the inner side of the card slot and the outer side of the card block are provided with sealing elements, which are elastic and used to seal the gap between the card slot and the card block.

[0011] Preferably, the first screw is located in the slot, the head of the first screw is provided with a V-shaped groove in the circumference, and the slot is provided with an operating hole on the side near the interior, the operating hole being flush with the first screw and aligned with the V-shaped groove.

[0012] Preferably, the tensioning structure includes a threaded sleeve located inside the locking block. The threaded sleeve is positioned to match the operating hole, and a through-hole is provided radially through the center of the threaded sleeve, with the through-hole aligned with the first screw.

[0013] Preferably, the threaded sleeve has a second screw axially threaded inside, the head of the second screw being tapered and adapted to a V-groove.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0030] A novel composite wall panel for low-rise prefabricated steel structure residential buildings, comprising:

[0031] Wall panel 1, wall panel 1 includes a wall panel body, and the wall panel body has a slot 14 and a block 15 on both sides, the slot 14 and the block 15 are adapted to each other;

[0032] The wall panel body includes two panels 11, several partitions 12 are vertically arranged between the two panels 11, and a filler 13 is provided between the panels 11 and the partitions 12.

[0033] Panel 11, partition 12, slot 14 and block 15 are made of a composite material of glass fiber and cement mortar and are integrally molded.

[0034] The filler 13 can be polyurethane foam or other thermal insulation materials such as rock wool.

[0035] A sealing element 16 is provided on the inner side of the slot 14 and the outer side of the block 15. The sealing element 16 is elastic and is used to seal the gap between the slot 14 and the block 15.

[0036] The seal 16 may be made of rubber material, and the seal 16 is bonded to the groove 14 and the block 15 with adhesive.

[0037] Connector 2, which includes a first screw 21 and a tensioning structure, is engaged with the tensioning structure to tension two adjacent wall panels 1 in the horizontal direction;

[0038] The first screw 21 is located in the slot 14. The head of the first screw 21 is provided with a V-shaped groove 22 in the circumferential direction. The slot 14 is provided with an operating hole 17 on the side near the interior. The height of the operating hole 17 is flush with the first screw 21 and aligned with the V-shaped groove 22.

[0039] The first screw 21 is threadedly installed in the center of the slot 14 and is perpendicular to the axis of the slot 14.

[0040] A plug 18 is snapped into the operating hole 17, and the plug 18 is used to seal the operating hole 17.

[0041] The tensioning structure includes a threaded sleeve 23, which is located inside the locking block 15. The position of the threaded sleeve 23 is adapted to the operating hole 17. A insertion hole 24 is provided radially through the middle of the threaded sleeve 23, and the insertion hole 24 is aligned with the first screw 21.

[0042] The threaded sleeve 23 is located on the indoor side of the clamping block 15. The threaded sleeve 23 is inserted into the clamping block 15, and the top surface of the threaded sleeve 23 is flush with the surface of the clamping block 15.

[0043] Several clamping plates 25 are axially welded to the outer side of the threaded sleeve 23. The clamping plates 25 are engaged with the clamping blocks 15 to prevent the threaded sleeve 23 from rotating.

[0044] After the card block 15 is inserted into the card slot 14, the first screw 21 can be inserted into the threaded sleeve 23 through the insertion hole 24.

[0045] The threaded sleeve 23 has an axial threaded connection to a second screw 26. The head of the second screw 26 is tapered and is adapted to the V-groove 22.

[0046] When the second screw 26 is tightened, the head of the second screw 26 can be inserted into the V-groove 22, thereby driving the first screw 21 to move towards the locking block 15, which in turn causes the two sealing elements 16 to press against each other to ensure sealing.

[0047] Meanwhile, the second screw 26 and the V-groove 22 engage to prevent the two adjacent wall panels 1 from separating.

[0048] Fastener 3 is used to fix the wall panel 1 and the main steel structure.

[0049] The fastener 3 includes an upper slot 31 and a lower slot 32, which are fixedly installed on the roof and the ground respectively. The wall panel 1 is snapped between the upper slot 31 and the lower slot 32, and the wall panel 1 can slide along the axial direction of the upper slot 31 and the lower slot 32.

[0050] The upper slot 31 and the lower slot 32 are used to prevent the wall panel 1 from moving back and forth and to limit the left and right movement path of the wall panel 1, so as to ensure that the slot 14 and the block 15 are properly engaged.

[0051] The depth of the upper slot 31 is at least twice the depth of the lower slot 32. There is a gap between the top surface of the wall panel 1 and the inner top surface of the upper slot 31. A pad 33 is slidably installed between the top surface of the wall panel 1 and the inner top surface of the upper slot 31.

[0052] During installation, first insert the wall panel 1 into the upper slot 31 until the top surface of the wall panel 1 abuts against the inner top surface of the upper slot 31. Keep the wall panel 1 vertical and slowly lower it so that the bottom of the wall panel 1 is inserted into the lower slot 32. Since the depth of the upper slot 31 is at least twice the depth of the lower slot 32, the top of the wall panel 1 will not come off the upper slot 31.

[0053] Inserting the pad 33 between the top surface of the wall panel 1 and the inner top surface of the upper slot 31 can prevent the wall panel 1 from sliding upward, thus completing the fixation of the wall panel 1.

[0054] The fastener 3 also includes a side sealing plate 34, which has an L-shaped cross-section. The side sealing plate 34 is welded and installed on the main steel structure and is fixedly connected to the wall panel 1 by screws, in order to seal the gap between the side of the wall panel 1 and the main steel structure.

[0055] In this embodiment, when the operator uses this device, the upper slot 31 and the lower slot 32 are first fixed to the roof and the ground by bolts or welding.

[0056] Insert the first wall panel 1 into the upper slot 31 until the top surface of the wall panel 1 abuts against the inner top surface of the upper slot 31. Keep the wall panel 1 vertical and slowly lower it so that the bottom of the wall panel 1 is inserted into the lower slot 32.

[0057] Push the first wall panel 1 to one end of the upper slot 31 and lower slot 32, and fix it with the side sealing plate 34.

[0058] Next, insert the second wall panel 1 between the upper slot 31 and the lower slot 32, and push the second wall panel 1 toward the first wall panel 1 until the card block 15 is inserted into the slot 14.

[0059] At this time, the first screw 21 can be inserted into the threaded sleeve 23 through the insertion hole 24.

[0060] Insert the screwdriver into the operating hole 17 to drive the second screw 26 to rotate, so that the second screw 26 is screwed into the threaded sleeve 23.

[0061] When the second screw 26 is tightened, the head of the second screw 26 can be inserted into the V-groove 22, thereby driving the first screw 21 to move towards the locking block 15, which in turn causes the two sealing elements 16 to press against each other to ensure sealing.

[0062] Install the remaining wall panels 1 at once. Note that for each wall panel 1 installed, the spacer 33 needs to be inserted between the top surface of the wall panel 1 and the inner top surface of the upper slot 31.

[0063] The side sealing plate 34 is used to fix the last wall panel 1 to the main steel structure.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
