Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology, specifically to an integrated prefabricated steel structure fireproof, heat-insulating, and decorative exterior wall and its construction process. Background Technology

[0002] Existing methods for splicing exterior walls often involve using bolts for mutual fixing, resulting in low installation efficiency, long installation times, and significant manpower requirements. This leads to resource waste and project delays. Furthermore, due to the excellent thermal conductivity and temperature sensitivity of steel structural materials, without cooling design, the steel plate frame is more susceptible to temperature effects in high-temperature environments, accelerating its aging process, reducing its strength and stability, shortening its service life, increasing the cost of building maintenance and exterior wall replacement, and affecting the stability and safety of the entire building structure. To address these issues, a prefabricated steel structure fireproof, thermal insulation, and decorative integrated exterior wall and its construction technology are provided. Summary of the Invention

[0003] The purpose of this invention is to address the problems mentioned in the background art by providing an integrated prefabricated steel structure fireproof, heat-insulating, and decorative exterior wall and its construction process. This invention features an efficient splicing mechanism, significantly shortens construction time, reduces construction costs, and can collect rainwater to cool the steel plate frame, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an integrated prefabricated steel structure fireproof, heat-insulating, and decorative exterior wall, comprising: a steel plate outer frame, a cavity extending through the upper part of the steel plate outer frame, a first lower fixing groove and a second lower fixing groove on the side of the steel plate outer frame, a limiting fixing plate below the first lower fixing groove, multiple sets of vertical fixing screws below the limiting fixing plate, a sliding groove on the side of the steel plate outer frame, multiple sets of splicing protrusions fixedly connected inside the sliding groove, multiple sets of splicing groove blocks fixedly connected to the other side of the steel plate outer frame, a rock wool sandwich panel fixedly connected inside the cavity, a porous sponge layer fixedly connected to the side of the rock wool sandwich panel, and a water storage and equalization mechanism above the rock wool sandwich panel;

[0005] The water storage and equalization mechanism includes a water receiving chute, a water storage tank is provided on the side of the water receiving chute, a water distribution and equalization box is fixedly connected below the water storage tank, multiple sets of evenly distributed equalization and drainage holes are opened below the water distribution and equalization box, a sliding plate groove is opened on the side of the water distribution and equalization box, a servo motor is fixedly connected below the water storage tank, a gear is fixedly connected to the rotating shaft of the servo motor, a movable adjustment slide plate is slidably connected in the sliding plate groove, multiple sets of adjustment and drainage holes are opened inside the movable adjustment slide plate, and a toothed plate is fixedly connected to the side of the movable adjustment slide plate.

[0006] As a further embodiment of the present invention: multiple sets of heat dissipation holes are opened on the side of the steel plate outer frame and penetrate into the cavity; a fixing through hole is opened on the side of the steel plate outer frame and penetrates the steel plate outer frame and the cavity; a horizontal fixing screw is installed inside the fixing through hole; two sets of inner slots are symmetrically opened on the inner side of the cavity; a lower insert block is fixedly connected to the lower part of the steel plate outer frame; side spring slots are opened on both sides of the lower insert block; a support spring is fixedly connected inside the side spring slot; and a trapezoidal top block is fixedly connected to the other end of the support spring.

[0007] As a further aspect of the present invention: the number of splicing protrusions and splicing grooves are corresponding, and the splicing protrusions and splicing grooves are compatible. When it is necessary to splice the integrated exterior wall in the horizontal direction, it is only necessary to unscrew the vertical fixing screw, remove the limiting fixing plate, align the splicing protrusion with the sliding groove, insert it and push it upward, so that the splicing protrusion is inserted into the splicing groove.

[0008] As a further embodiment of the present invention: multiple sets of through holes are provided on the inner side of the limiting and fixing plate, and multiple sets of threaded holes adapted to the vertical fixing screw are provided on the inner side of the first lower fixing groove and the second lower fixing groove. After the splicing protrusion and splicing groove are spliced, the vertical fixing screw passes through the through hole provided on the inner side of the limiting and fixing plate and is threadedly connected to the threaded hole provided on the inner side of the first lower fixing groove and the second lower fixing groove, thereby completing the horizontal splicing of the integrated exterior wall.

[0009] As a further embodiment of the present invention: the number and spacing of the adjustable drainage holes are the same as the number of equal flow drainage holes, and the gear meshes with the gear plate.

[0010] As a further embodiment of the present invention: the water storage and equalization mechanism is fixedly connected to the top of the rock wool sandwich panel via a water storage tank, the water distribution and equalization box is attached to the top of the porous sponge layer, and the inside of the water receiving trough is connected to the inside of the water storage tank via a pipe.

[0011] As a further embodiment of the present invention: the fixing through hole extends from the side of the steel plate outer frame through the cavity to the other side of the steel plate outer frame.

[0012] As a further embodiment of the present invention: the outer wall and the inner wall can be fixed by passing through one side of the steel plate outer frame with the horizontal fixing screw, and then passing through the rock wool sandwich panel and the porous sponge layer inside the cavity respectively.

[0013] As a further aspect of the present invention: when the supporting spring is not subjected to external force, the trapezoidal top block is partially located inside the side spring groove. When it is necessary to splice the integrated exterior wall in the vertical direction, first align the lower insert block with the cavity of another integrated exterior wall and insert it from above. The inclined surface of the trapezoidal top block is pressed inward by force, the supporting spring contracts, and after they fit tightly, the trapezoidal top block is located on the side of the inner slot. The supporting spring extends and pushes the trapezoidal top block into the inner slot, thus splicing the two sets of integrated exterior walls tightly in the vertical direction.

[0014] As a further embodiment of the present invention: the construction process of an integrated prefabricated steel structure fireproof, heat-insulating, and decorative exterior wall includes the following steps:

[0015] Step 1: When the integrated exterior wall needs to be spliced ​​horizontally, first, unscrew the vertical fixing screw and easily remove the limiting fixing plate to prepare for splicing. Next, align the splicing protrusion with the sliding groove and push it upward to ensure that the splicing protrusion can be fully inserted into the splicing groove. At this time, since the limiting fixing plate has a through hole on the inside, and the first and second lower fixing grooves also have threaded holes that match the vertical fixing screw, after the splicing protrusion and splicing groove are spliced, re-penetrate the vertical fixing screw through the through hole on the inside of the limiting fixing plate and connect it with the threaded holes on the inside of the first and second lower fixing grooves. This will securely complete the horizontal splicing of the integrated exterior wall.

[0016] Step 2: When vertical splicing of integrated exterior walls is required, first, align the lower insert of one integrated exterior wall with the cavity of another integrated exterior wall and slowly insert it from above. During the insertion process, the inclined surface of the trapezoidal top block will be subjected to pressure and squeezed inward, and the support spring will contract accordingly. When the two integrated exterior walls are tightly attached, the support spring will naturally extend, pushing the trapezoidal top block into the inner groove, achieving a tight vertical splicing. This design not only ensures the stability of the splicing but also greatly simplifies the construction process.

[0017] Step 3: By using horizontal fixing screws to penetrate one side of the steel plate outer frame, the rock wool sandwich panel inside the cavity, and the porous sponge layer, the assembled outer wall and inner wall can be fixed together.

[0018] Step 4: The water collection chute collects rainwater or other water sources and introduces the water into the storage tank through pipes. When the temperature of the steel plate frame is high, the servo motor can be started to drive the gears to rotate. The rotation of the gears will cause the moving adjustment slide to move left and right in the slide groove, thereby adjusting the size of the overlapping part of the adjustment drain hole and the equalizing drain hole. In this way, the rate at which water flows from inside the storage tank to the porous sponge layer can be precisely controlled. After absorbing water, the porous sponge layer will use its porous shape to accelerate the evaporation of water, thereby cooling the steel plate frame. At the same time, the heat dissipation perforations will promote air circulation in the cavity, further accelerating the evaporation of water and the heat dissipation effect. This automatic cooling design delays the aging of the exterior wall steel plate frame and extends the service life of the exterior wall. The rock wool sandwich panel, as a fireproof layer, has excellent fire resistance. At the same time, the porous sponge layer not only has a cooling function, but also has a certain heat insulation effect, which can reduce the temperature difference between indoors and outdoors.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention significantly improves the splicing efficiency of exterior walls through a convenient and quick splicing design. Horizontal splicing is achieved by unscrewing the fixing screws, removing the fixing plate, inserting the protrusion, and re-fixing the fixing plate, resulting in a fast and stable connection. Vertical splicing is achieved through the cooperation of the lower insert block and the inner slot, utilizing the automatic action of the support spring and the trapezoidal top block to ensure a tight and stable connection. This efficient splicing mechanism greatly shortens construction time and reduces construction costs.

[0021] 2. In this invention, rainwater is collected through a water storage and equalization mechanism, and the rate at which water flows to the porous sponge layer is precisely controlled by the cooperation of a servo motor and an adjusting slide plate. The porous sponge layer uses its porous shape to accelerate the evaporation of water and cool the steel plate frame. At the same time, the heat dissipation perforations promote air circulation in the cavity, further enhancing the cooling effect. This automatic cooling system effectively delays the aging of the exterior wall steel plate frame, extends the service life of the exterior wall, and also improves the comfort and energy efficiency of the building.

[0033] Reference Figures 1 to 8 In this embodiment of the invention, the prefabricated steel structure fireproof, heat-insulating, and decorative integrated exterior wall and its construction process include: a steel plate outer frame 1, a cavity 2 extending through the upper part of the steel plate outer frame 1, a first lower fixing groove 11 and a second lower fixing groove 12 on the side of the steel plate outer frame 1, a limiting fixing plate 13 below the first lower fixing groove 11, multiple sets of vertical fixing screws 14 below the limiting fixing plate 13, a sliding groove 15 on the side of the steel plate outer frame 1, multiple sets of splicing protrusions 16 fixedly connected inside the sliding groove 15, and multiple sets of splicing groove blocks 17 fixedly connected to the other side of the steel plate outer frame 1. The number of splicing protrusions 16 and splicing groove blocks 17 corresponds, and the splicing protrusions 16 and splicing groove blocks 17 are compatible. When it is necessary to splice the integrated exterior wall horizontally, only the vertical fixing screws need to be unscrewed. 14. Remove the limiting fixing plate 13, align the splicing protrusion 16 with the sliding groove 15 and push it upward so that the splicing protrusion 16 is inserted into the splicing groove 17. The limiting fixing plate 13 has multiple sets of through holes on its inner side. The first lower fixing groove 11 and the second lower fixing groove 12 have multiple sets of threaded holes that are compatible with the vertical fixing screw 14 on their inner sides. After the splicing protrusion 16 and the splicing groove 17 are spliced, the vertical fixing screw 14 passes through the through hole on the inner side of the limiting fixing plate 13 and is threadedly connected to the threaded hole on the inner side of the first lower fixing groove 11 and the second lower fixing groove 12, thus completing the horizontal splicing of the integrated exterior wall. A rock wool sandwich panel 18 is fixedly connected inside the cavity 2. A porous sponge layer 19 is fixedly connected to the side of the rock wool sandwich panel 18. A water storage and equalization mechanism 20 is provided above the rock wool sandwich panel 18.

[0034] The water storage and equalization mechanism 20 includes a water receiving chute 201, a water storage tank 202 on the side of the water receiving chute 201, and a water distribution and equalization box 203 fixedly connected below the water storage tank 202. Multiple sets of evenly distributed equalization and drainage holes 204 are opened below the water distribution and equalization box 203. A sliding plate groove 205 is opened on the side of the water distribution and equalization box 203. A servo motor 206 is fixedly connected below the water storage tank 202, and a gear 207 is fixedly connected to the rotating shaft of the servo motor 206. A movable adjustment slide plate 208 is slidably connected inside the sliding plate groove 205. Multiple sets of adjustment drainage holes 209 are opened inside the movable adjustment slide plate 208. A toothed plate 2010 is fixedly connected to the side of the movable adjustment slide plate 208. The number and spacing of the adjustment drainage holes 209 are the same as the number of equalization and drainage holes 204. The gear 207 meshes with the toothed plate 2010. The rotation of the servo motor 206... The movement can drive the gear 207 to rotate, thereby driving the movable adjustment slide 208, which is fixedly connected to the toothed plate 2010, to move left and right, thereby adjusting the size of the overlapping part of the adjustment drain hole 209 and the flow equalization drain hole 204, thus transferring the water inside the water storage tank 202 to the porous sponge layer 19, evaporating and cooling the steel plate outer frame 1 that is in close contact with the porous sponge layer 19. The porous shape of the porous sponge layer 19 can accelerate the evaporation of water. The heat dissipation perforation 3 can promote the air circulation in the cavity 2, accelerate the evaporation of water in the porous sponge layer 19, cool the steel plate outer frame 1, and extend its service life. The water storage and flow equalization mechanism 20 is fixedly connected to the top of the rock wool sandwich panel 18 through the water storage tank 202. The water pouring and flow equalization box 203 is attached to the top of the porous sponge layer 19. The water receiving chute 201 is connected to the inside of the water storage tank 202 through a pipe.

[0035] Reference Figures 1 to 5The steel plate outer frame 1 has multiple sets of heat dissipation perforations 3 that penetrate into the cavity 2 on its side. The steel plate outer frame 1 also has a fixing through hole 4 that penetrates both the steel plate outer frame 1 and the cavity 2. The fixing through hole 4 extends from the side of the steel plate outer frame 1 through the cavity 2 and exits from the other side of the steel plate outer frame 1. A horizontal fixing screw 5 is installed inside the fixing through hole 4. The horizontal fixing screw 5 passes through one side of the steel plate outer frame 1 and then through the rock wool sandwich panel 18 and the porous sponge layer 19 inside the cavity 2 to fix the outer wall to the inner wall. Two sets of internal slots 6 are symmetrically provided inside the cavity 2. A lower insert block 7 is fixedly connected to the bottom of the steel plate outer frame 1. Side openings are provided on both sides of the lower insert block 7. A spring groove 8 is fixedly connected to a support spring 9 inside the side spring groove 8. A trapezoidal top block 10 is fixedly connected to the other end of the support spring 9. When the support spring 9 is not subjected to external force, the trapezoidal top block 10 is partially located inside the side spring groove 8. When it is necessary to splice the integrated exterior wall in the vertical direction, first align the lower insert 7 with the cavity 2 of the other integrated exterior wall and insert it from above. The inclined surface of the trapezoidal top block 10 is pressed inward by force, the support spring 9 contracts, and after it fits tightly, the trapezoidal top block 10 is located on the side of the inner slot 6. The support spring 9 extends and pushes the trapezoidal top block 10 into the inner slot 6, thus splicing the two sets of integrated exterior walls tightly in the vertical direction.

[0036] The construction process of prefabricated steel structure fireproof, thermal insulation and decorative integrated exterior wall includes the following steps:

[0037] Step 1: When it is necessary to splice the integrated exterior wall horizontally, firstly, unscrew the vertical fixing screw 14 and easily remove the limiting fixing plate 13 to prepare for splicing. Next, align the splicing protrusion 16 with the sliding groove 15 and insert it, and push it upward to ensure that the splicing protrusion 16 can be completely inserted into the splicing groove block 17. At this time, since the limiting fixing plate 13 has a through hole on the inner side, and the first lower fixing groove 11 and the second lower fixing groove 12 also have threaded holes that are compatible with the vertical fixing screw 14, after the splicing protrusion 16 and the splicing groove block 17 are spliced, re-penetrate the vertical fixing screw 14 through the through hole on the inner side of the limiting fixing plate 13 and connect it with the threaded holes on the inner side of the first lower fixing groove 11 and the second lower fixing groove 12. In this way, the splicing of the integrated exterior wall in the horizontal direction is completed securely.

[0038] Step 2: When vertical splicing of integrated exterior walls is required, first, align the lower insert 7 of one integrated exterior wall with the cavity 2 of another integrated exterior wall and slowly insert it from above. During the insertion process, the inclined surface of the trapezoidal top block 10 will be subjected to pressure and squeezed inward, and the support spring 9 will contract accordingly. When the two integrated exterior walls are tightly attached, the support spring 9 will naturally extend, pushing the trapezoidal top block 10 into the inner slot 6, achieving a tight vertical splicing. This design not only ensures the stability of the splicing but also greatly simplifies the construction process.

[0039] Step 3: By using horizontal fixing screws 5 to penetrate one side of the steel plate outer frame 1, the rock wool sandwich panel 18 inside the cavity 2, and the porous sponge layer 19, the assembled outer wall and inner wall can be fixed together.

[0040] Step 4: The water receiving chute 201 collects rainwater or other water sources and introduces the water into the water storage tank 202 through pipes. When the temperature of the steel plate outer frame 1 is high, the servo motor 206 can be started to work, driving the gear 207 to rotate. The rotation of the gear 207 will drive the moving adjusting slide plate 208 to move left and right in the slide plate groove 205, thereby adjusting the size of the overlapping part of the adjusting drain hole 209 and the equalizing drain hole 204. In this way, the rate at which water flows from inside the water storage tank 202 to the porous sponge layer 19 can be precisely controlled. After the porous sponge layer 19 absorbs water... The porous structure accelerates moisture evaporation, thereby cooling the steel frame 1. At the same time, the heat dissipation perforations 3 promote air circulation in the cavity 2, further accelerating moisture evaporation and heat dissipation. This automatic cooling design slows down the aging of the steel frame 1 and extends the service life of the exterior wall. The rock wool sandwich panel 18, as a fireproof layer, has excellent fire resistance. Meanwhile, the porous sponge layer 19 not only has a cooling function but also a certain degree of heat preservation, which can reduce the temperature difference between indoors and outdoors, improve the building's heat preservation performance, and provide a safer and more comfortable living environment for the building.

In this way, the splicing of the integrated exterior wall in the horizontal direction is completed steadily. Step 2: When it is necessary to vertically splice the integrated exterior wall, firstly, align the lower insert (7) of one integrated exterior wall with the cavity (2) of another integrated exterior wall and slowly insert it from above. During the insertion process, the inclined surface of the trapezoidal top block (10) will be subjected to pressure and squeezed inward, and the support spring (9) will contract accordingly. When the two integrated exterior walls are tightly attached, the support spring (9) will naturally extend and push the trapezoidal top block (10) into the inner slot (6) to achieve a tight vertical splicing. This design not only ensures the stability of the splicing, but also greatly simplifies the construction process. Step 3: By using horizontal fixing screws (5) to penetrate one side of the steel plate outer frame (1), the rock wool sandwich panel (18) inside the cavity (2) and the porous sponge layer (19), the spliced ​​outer wall and inner wall can be fixed together; Step 4: The water collection chute (201) is responsible for collecting rainwater or other water sources and introducing the water into the water storage tank (202) through pipes. When the temperature of the steel plate outer frame (1) is high, the servo motor (206) can be started to work, driving the gear (207) to rotate. The rotation of the gear (207) will drive the moving adjustment slide plate (208) to move left and right in the slide plate groove (205), thereby adjusting the size of the overlapping part of the adjustment drain hole (209) and the equalization drain hole (204). In this way, the flow of water inside the water storage tank (202) to the porous sponge layer can be precisely controlled. At a rate of 19), after the porous sponge layer (19) absorbs water, it will use its porous shape to accelerate the evaporation of water, thereby cooling the steel plate frame (1). At the same time, the heat dissipation perforations (3) will promote the air circulation in the cavity (2), further accelerating the evaporation of water and the heat dissipation effect. This automatic cooling design delays the aging of the outer wall steel plate frame (1) and extends the service life of the outer wall. The rock wool sandwich panel (18) has excellent fire resistance as a fireproof layer. At the same time, the porous sponge layer (19) not only has a cooling function, but also has a certain heat preservation effect, which can reduce the temperature difference between indoors and outdoors.
