Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a thermal insulation structure of a wall, which is suitable for use in a steel structure prefabricated wall. Background Art

[0002] Steel structures are a new type of building. Compared to traditional concrete buildings, steel structures use steel plates or steel sections instead of reinforced concrete, resulting in higher strength and improved earthquake resistance. Furthermore, because components can be factory-fabricated and installed on-site, construction time is significantly reduced. The reusability of steel significantly reduces construction waste, making it more environmentally friendly. Consequently, steel structures are widely adopted worldwide for both industrial and residential construction.

[0003] Patent publication number CN111636584A provides a prefabricated low-energy wall system for buildings, comprising a steel structure and wall panels. The wall panels are mounted on the outside of the steel structure and connected to the steel structure using a first connecting member. The wall panels are prefabricated insulation panels, and adjacent prefabricated insulation panels are connected using a second connecting member. Sealing strips are installed in the gaps between the prefabricated insulation panels. Both the first and second connecting members are installed inside the building and extend no deeper than half the thickness of the prefabricated insulation panels. The prefabricated low-energy wall system of the present invention includes sealing strips installed between the wall panels to ensure the wall's tightness.

[0004] Steel plates or steel sections are used as the main supporting body of the building, and then plates are attached to the supporting body and fixed to the supporting body with bolts or screws. They are used as the walls of the building. The plates used have the functions of thermal insulation, heat insulation and noise reduction. However, in the actual construction process, various types of bolts or partial welding are required, which makes the construction more complicated, consuming manpower and financial resources. In addition, the plates exposed to the sun will crack and need to be replaced. The early construction and fixing method makes the later dismantling more troublesome. Summary of the Invention

[0005] The main purpose of the present invention is to provide a thermal insulation structure for a wall, which can not only realize the fast and convenient installation of a steel structure assembled wall, but also achieve the effects of thermal insulation, heat insulation and noise reduction.

[0006] To achieve the above-mentioned purpose, the present invention proposes a thermal insulation structure of the wall, comprising wall steel columns, and horizontal plates fixedly connected horizontally between two adjacent wall steel columns; a plurality of clamping blocks are provided on both sides of each horizontal plate, and the clamping blocks are L-shaped, one end of the clamping block is welded to the horizontal plate, and the other end of the clamping block points vertically upwards, an outer wall panel is arranged on the outer side of the horizontal plate, and an inner wall panel is arranged on the inner side of the horizontal plate; a hanging plate is provided at the upper and lower positions of the inner side surfaces of the outer wall panel and the inner wall panel, and the cross section of the hanging plate is L-shaped, one end of the hanging plate is fixed to the inner side surfaces of the corresponding outer wall panel and inner wall panel, the other end of the hanging plate points vertically downwards and is buckled on the clamping block, and the gap between the outer wall panel and the inner wall panel is filled with a foaming agent; the assembled wall, that is, the wall is prepared and produced in advance, and the wall is divided into a plurality of small modules for easy transportation and installation. The plate body of the outer wall panel is generally made of outer wall insulation The outer wall panels are made of warm boards, and the inner wall panels are made of polystyrene boards. The outer wall panels and the inner wall panels are fixed to the blocks on the horizontal boards through hanging panels, and then foaming agent is poured into the gap between the outer wall panels and the inner wall panels. The foaming agent expands and fills the gap. At the same time, the foaming agent expands and squeezes the outer wall panels and the inner wall panels to fix them. It can not only realize the fast and convenient installation of steel structure prefabricated walls, but also achieve the effects of thermal insulation, heat insulation and noise reduction. In actual use, the outer wall panels are exposed to the sun and are prone to cracking. After cracking, rainwater penetrates. At this time, the outer wall panels need to be replaced. The cracked outer wall panels are broken off, and then the hanging panels are exposed. The hanging panels are removed. There is a concave part in the foaming agent at this position, which is the concave part left by the original cracked outer wall panels. At this time, the new modular outer wall panels can be buckled on. The replacement is also relatively convenient and quick, and will not damage the surrounding modular outer wall panels, reducing losses.

[0007] Preferably, a concave point is provided on the vertical inner side wall of each card block; a through hole is provided on the vertical part of each hanging plate, and a limit pin is provided in the through hole, and the limit pin is slidably connected in the through hole by a compression spring, and the outer end of the limit pin is close to the concave point, and a cam block is provided on one side of the inner end of the limit pin, and the cam block is rotatably connected in the through hole, and the outer ring of the cam block is fixed with a lever; in order to facilitate the installation of the inner and outer wall panels, the hanging plate is hung on the card block, and the hanging plate and the card block are in a loose state at this time. At the same time, the gap between the inner and outer wall panels is narrow, and some wrenches or screwdrivers are difficult to operate on the fastening bolts, especially near the crossbeam position of the horizontal steel structure, where the inner and outer wall panels are connected. The upper edge of the panel is close to the lower surface of the beam and the operating space is limited. Therefore, a cam block and a limit pin are provided to avoid the inconvenience of tightening the bolts. First, push the lever downward, and the lever drives the cam block to rotate. The convex part of the cam block presses on the limit pin, and the inner end of the limit pin protrudes from the vertical inner wall of the hanging panel. Then hang the hanging panel on the inner wall panel or the outer wall panel on the block, and adjust the wall panel left and right. When the inner end of the limit pin is embedded in the concave point, the inner wall panel and the outer wall panel are fixed. When the foaming agent is injected, the inner wall panel and the outer wall panel can resist the extrusion force of the expansion of the foaming agent, thereby ensuring the stability of the inner wall panel and the outer wall panel and reducing the possibility of movement of the inner wall panel and the outer wall panel.

[0008] Preferably, the cam block includes a rotating shaft, a push rod and a block body; the two ends of the rotating shaft are fixed in the through hole, and a plurality of limit strips are evenly fixed on the outer ring of the rotating shaft.

When the outer end of the push rod is placed in the groove, the inner end of the push rod is embedded in the gap between two adjacent limit bars. At this time, the block body and the rotating shaft are fixed, which improves the stability of the cam block, thereby improving the stability of the vertical inner side wall of the hanging plate where the outer end of the limit pin protrudes, and then ensures that the limit pin is stably embedded in the groove.

[0009] Preferably, a socket is provided on one side of the inner wall panel, and a plug is fixedly connected to the other end of the inner wall panel. For two adjacent inner wall panels on the left and right, the plug on the right inner wall panel is inserted into the socket on the left inner wall panel; a pipe is laid inside the inner wall panel, and the pipe is bent and coiled inside the inner wall panel, with both ends of the pipe connected to the socket and the plug respectively; a pipe is set inside the inner wall panel, and the end of the external hot water pipe is connected to the socket on one inner wall panel, and then hot water is injected into the pipe, so that the surface of the inner wall panel is heated, and the house is heated to provide users with a comfortable living environment in winter; and modular inner wall panels, according to user needs, some areas in the house do not require heating, and at this time, hot water is not passed into the inner wall in the area, or the height of the inner wall panel required to be heated, the hot water pipe can be connected to the inner wall panel of the corresponding height, and it can be installed flexibly.

[0010] Preferably, there is a gap between the left and right adjacent inner wall panels, the gap distance is 0.4-0.6CM, and a notch is opened on the inner vertical edge of the inner wall panel, and the notch is in the shape of a quarter circle; a gap of 0.4-0.6CM is left between the inner wall panels, the purpose of which is to allow the foaming agent to penetrate into the gap. In actual installation, there are gaps between the inner wall panels, and these gaps cannot be completely avoided. For this reason, the gaps are deliberately flowed out so that the foaming agent can smoothly penetrate into the gaps, so that the foaming agent can fully expand in the gaps. At the same time, limit pins are set to fix the inner wall panels, which helps to seal and fill the gaps. At the same time, a gap of 0.4-0.6CM is also reserved between the outer wall panels, which is also deliberately allowed to allow the foaming agent to smoothly flow into the gaps and expand and fill the gaps.

[0011] Preferably, a plurality of pits are evenly arranged on the inner wall of the inner wall panel, the pits are spherical, and the outer diameter of the pits is smaller than the inner diameter of the pits; the pits are arranged on the inner wall of the inner wall panel so that the foaming agent can flow into the pits, effectively increasing the contact area between the inner wall of the inner wall panel and the foaming agent, and improving the stability of the inner wall panel after being fixed.

A plug is fixedly connected to the inward position of the arc seat, and the arc seat is half wrapped around the outer ring of the insert, and the plug is filled into the water inlet. After the pipeline has been used for a long time, scale remains in the pipeline and needs to be cleaned. Since the curved and spiral circumference of the pipeline in the inner wall panel is long, the traditional pulse cleaning method is difficult to be competent. For this reason, the inner wall panels are cleaned modularly one by one. First, the caulking plate is picked out, and the gap between the two adjacent inner wall panels is cleaned. The gap leaks out, and then the water inlet pipe of the pulse cleaning machine is inserted into the socket in the inner wall panel, or into the water inlet hole on the insert pipe exposed in the gap, and then the water outlet pipe of the pulse cleaning machine is inserted into the insert pipe on the inner wall panel, that is, the outlet pipe is inserted into the water inlet hole opened on the outer wall of the insert pipe, and clean water flows in from the water inlet pipe, flows through the pipe in the inner wall panel, and then is discharged from the outlet pipe. The following inner wall panels are cleaned one by one according to the above cleaning method, which reduces the cleaning pressure of the pulse cleaning machine and ensures the cleanliness of the pipe in each inner wall panel; after cleaning, the caulking plate is embedded in the gap again, the arc-shaped seat is half-wrapped on the insert pipe, the plug is inserted into the water inlet hole, and the water inlet hole is filled and sealed.

When the rod is not in use, it is stored so that the rod can be given to the cleaning personnel for operation.

[0014] Preferably, a plurality of connecting rods are provided on the upper and lower inner end surfaces of the caulking plate, one end of the connecting rod is vertically fixed to the caulking plate, and the other end of the connecting rod is inserted into the gap between the two inner wall panels; the connecting rod is arranged so that after the caulking plate is embedded in the gap, the other end of the connecting rod can touch the foaming agent, and the connecting rod is fixed in the gap, thereby fixing the caulking plate in the gap, and when the gap plate is picked out, the caulking plate can be dragged with force, and when backfilling, the connecting rod can be inserted into the original hole.

[0015] Preferably, a plurality of semicircular grooves are provided on the surface of the connecting rod to increase the contact area with the foaming agent; rubber pads are provided on the side walls of the caulking plate, and the rubber pads are provided through the two side walls of the caulking plate and protrude from the surface of the two side walls of the caulking plate; the provided rubber pads increase the extrusion force between the caulking plate and the gap, because after the connecting rod is pulled out once, a gap appears between the connecting rod and the foaming agent agglomerate, and the looseness occurs, and the rubber pads are provided to make up for the connection strength between the connecting rod and the foaming agent, thereby ensuring that the protrusions stably fill and seal the water inlet hole.

[0016] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0017] (1) In the present invention, a foaming agent is poured into the gap between the exterior wall panel and the interior wall panel. The foaming agent expands and fills the gap. At the same time, the foaming agent expands and squeezes the exterior wall panel and the interior wall panel to fix them. This can not only realize the fast and convenient installation of the steel structure prefabricated wall, but also achieve the effects of heat insulation, heat insulation and noise reduction. In actual use, the exterior wall panel is exposed to the sun and is prone to cracking. After cracking, rainwater penetrates. At this time, the exterior wall panel needs to be replaced. The cracked exterior wall panel is broken and then the hanging panel is exposed. The hanging panel is removed. There is a concave part in the foaming agent at this position, that is, the concave part left by the original cracked exterior wall panel. At this time, the new modular exterior wall panel can be buckled on. The replacement is also relatively convenient and quick, and the surrounding modular exterior wall panels are not damaged, thereby reducing losses.

[0018] (2) The convex portion of the cam block of the present invention is pressed against the limit pin, and the inner end of the limit pin protrudes from the vertical inner wall of the hanging plate. Then, the hanging plate on the inner wall panel or the outer wall panel is hung on the clamping block, and the wall panel is adjusted left and right. When the inner end of the limit pin is embedded in the concave point, the inner wall panel and the outer wall panel are fixed. When the foaming agent is injected, the inner wall panel and the outer wall panel can resist the extrusion force of the expanding foaming agent, thereby ensuring the stability of the inner wall panel and the outer wall panel and reducing the possibility of movement of the inner wall panel and the outer wall panel.

[0044] A plurality of semicircular grooves are provided on the surface of the connecting rod 29 to increase the contact area with the foaming agent; rubber pads 30 are provided on the side walls of the caulking plate 23, and the rubber pads 30 are provided through the two side walls of the caulking plate 23 and protrude from the surface of the two side walls of the caulking plate 23; the provided rubber pads 30 increase the extrusion force between the caulking plate 23 and the gap, because after the connecting rod 29 is pulled out once, a gap appears between the connecting rod 29 and the foaming agent agglomerate, which becomes loose, and the rubber pads 30 are provided to make up for the connection strength between the connecting rod 29 and the foaming agent, thereby ensuring that the protrusions 27 stably fill and seal the water inlet 22.

[0045] Working principle: prefabricated wall, that is, the wall is prepared in advance and divided into multiple small modules for easy transportation and installation. The outer wall panel 4 is generally made of outer wall insulation board, and the inner wall panel 5 is made of polystyrene board. The outer wall panel 4 and the inner wall panel 5 are fixed on the block 3 on the horizontal plate 2 through the hanging plate 6. Then, the foaming agent is poured into the gap between the outer wall panel 4 and the inner wall panel 5. The foaming agent expands and fills the gap. At the same time, the foaming agent expands and squeezes the outer wall panel 4 and the inner wall panel 5 to fix them, which can realize the steel structure prefabrication. The wall can be installed quickly and conveniently, and can also achieve the effects of heat insulation and noise reduction. In actual use, the exterior wall panels 4 are exposed to the sun and are prone to cracking, which allows rainwater to penetrate. At this time, the exterior wall panels 4 need to be replaced. The cracked exterior wall panels 4 are broken, and then the hanging panels 6 are exposed. The hanging panels 6 are removed. There is a concave part in the foaming agent at this position, which is the concave part left by the original cracked exterior wall panels 4. At this time, the new modular exterior wall panels 4 can be buckled in. The replacement is also relatively convenient and quick, and the surrounding modular exterior wall panels 4 are not damaged, reducing losses.

[0046] In order to facilitate the installation of the inner wall panels 5 and the outer wall panels 4, the hanging panels 6 are hung on the clamping blocks 3. At this time, the hanging panels 6 and the clamping blocks 3 are in a loose state. At the same time, the gap between the inner wall panels 5 and the outer wall panels 4 is narrow, and some wrenches or screwdrivers are difficult to operate on the fastening bolts, especially near the crossbeam position of the horizontal steel structure. The upper edges of the inner wall panels 5 and the outer wall panels 4 are close to the lower surface of the crossbeam position, and the operating space is limited. For this reason, a cam block 10 and a limit pin 9 are provided to avoid the inconvenience of tightening the bolts. First, push the lever 11 downward, and the lever 11 drives the cam block 10 to rotate, and the convex part of the cam block 10 presses on the limit pin 9. The inner end of the limit pin 9 protrudes from the vertical inner side wall of the hanging plate 6. Then, the inner wall panel 5 or the hanging plate 6 on the outer wall panel 4 is hung on the clamping block 3, and the wall panel is adjusted left and right. When the inner end of the limit pin 9 is embedded in the concave point 7, the inner wall panel 5 and the outer wall panel 4 are fixed. When the foaming agent is injected, the inner wall panel 5 and the outer wall panel 4 can resist the extrusion force of the expanding foaming agent, thereby ensuring the stability of the inner wall panel 5 and the outer wall panel 4 and reducing the possibility of movement of the inner wall panel 5 and the outer wall panel 4.

[0047] When the hanging plate 6 moves on the card block 3 and the limit pin 9 finds the concave point 7, the hanging plate 6 collides with the card block 3, and the generated vibration force easily causes the cam block 10 to rotate by itself, so that the convex part of the cam block 10 disengages from the inner end surface of the limit pin 9, and the limit pin 9 is ineffectively squeezed into the groove 16; when the cam block 10 is rotated, the inner end of the push rod 13 gradually approaches the limit bar 15, and at the same time, the outer end of the push rod 13 is gradually placed in the groove 16. When the outer end of the push rod 13 is placed in the groove 16, the inner end of the push rod 13 is embedded in the gap between the two adjacent limit bars 15. At this time, the block 14 and the rotating shaft 12 are fixed, which improves the stability of the cam block 10, thereby improving the stability of the vertical inner wall of the hanging plate 6 where the outer end of the limit pin 9 protrudes, and then ensures that the limit pin 9 is stably embedded in the groove 16;

[0048] A pipe 19 is provided inside the inner wall panel 5. The end of the external hot water pipe is connected to the socket 17 on one side of the inner wall panel 5. Then, hot water is injected into the pipe 19, causing the surface of the inner wall panel 5 to heat up, thereby heating the house and providing a comfortable living environment for users in winter. The modular inner wall panel 5 can be installed flexibly according to user needs. Some areas in the house do not require heating. In this case, hot water is not supplied to the inner walls of the area. Alternatively, if the height of the inner wall panel 5 to be heated is desired, the hot water pipe can be connected to the inner wall panel 5 at the corresponding height.

[0049] A gap of 0.4-0.6CM is left between the inner wall panels 5, so that the foaming agent can also penetrate into the gap. In actual installation, there are gaps between the inner wall panels 5, and these gaps cannot be completely avoided. For this reason, the gaps are deliberately left so that the foaming agent can smoothly penetrate into the gaps and fully expand in the gaps. At the same time, a limit pin 9 is provided to fix the inner wall panels 5, which helps to seal and fill the gaps. At the same time, a gap of 0.4-0.6CM is also reserved between the outer wall panels 4, so that the foaming agent can smoothly flow into the gaps and expand and fill the gaps.

[0050] A recess 21 is provided on the inner wall of the inner wall panel 5 so that the foaming agent can flow into the recess 21, effectively increasing the contact area between the inner wall of the inner wall panel 5 and the foaming agent, thereby improving the stability of the inner wall panel 5 after being fixed;

[0051] After long-term use, the pipe 19 will have scale remaining in it and needs to be cleaned. Since the pipe 19 in the inner wall panel 5 has a long curved circumference, the traditional pulse cleaning method is not competent. Therefore, the modular inner wall panels 5 are cleaned one by one. First, the caulking plate 23 is removed to expose the gap between the two adjacent inner wall panels 5. Then, the water inlet pipe of the pulse cleaning machine is inserted into the socket 17 in the inner wall panel 5, or into the water inlet hole 22 on the intubation pipe 18 exposed in the gap. Then, the water outlet pipe of the pulse cleaning machine is inserted into the intubation pipe 1 on the inner wall panel 5. 8. That is, the outlet pipe is inserted into the water inlet hole 22 provided on the outer wall of the insert 18. Clean water flows in from the water inlet pipe, flows through the pipe 19 in the inner wall panel 5, and is then discharged from the outlet pipe. The following inner wall panels 5 are cleaned individually according to the above-mentioned cleaning method, reducing the cleaning pressure of the pulse cleaning machine while ensuring the cleanliness of the pipe 19 in each inner wall panel 5. After cleaning, the caulking plate 23 is re-inserted into the gap, the arc-shaped seat 24 is half-wrapped on the insert 18, and the plug 25 is inserted into the water inlet hole 22 to fill and seal the water inlet hole 22.

[0052] An insertion rod 26 is provided to fit into the insertion tube 18 in the gap. When cleaning the pipe 19, the water outlet pipe and the water inlet pipe of the pulse cleaning machine are connected to the through hole 28 in the insertion rod 26. Then, the insertion rod 26 is inserted into the gap so that the protrusion 27 is embedded in the water inlet hole 22, which facilitates the connection between the water inlet hole 22 and the pulse cleaning machine and facilitates the operation of the cleaning staff. When the insertion rod 26 is not in use, it is stored so that the insertion rod 26 can be given to the cleaning staff for operation.

[0053] A connecting rod 29 is provided so that after the caulking plate 23 is embedded in the gap, the other end of the connecting rod 29 can touch the foaming agent, fixing the connecting rod 29 in the gap, thereby fixing the caulking plate 23 in the gap, and when the gap plate is pulled out, the caulking plate 23 can be dragged with force, and when backfilling, the connecting rod 29 can be inserted into the original hole; the rubber pad 30 is provided to increase the extrusion force between the caulking plate 23 and the gap, because after the connecting rod 29 is pulled out once, a gap appears between the connecting rod 29 and the foaming agent agglomerate, and it becomes loose. The rubber pad 30 is provided to make up for the connection strength between the connecting rod 29 and the foaming agent, thereby ensuring that the protrusion 27 stably fills and seals the water inlet hole 22.
