Description

Technical Field

[0001] The present application relates to the field of building technology, and in particular to an assembled light steel composite wall panel. Background Art

[0002] The current light steel profile structural wall panels have a loud hollow sound when knocked, and the wall's earthquake resistance, heat preservation, fire resistance, and weather resistance need to be improved. The hollow sound, poor airtightness, and poor corrosion resistance of the wall are the main factors restricting the promotion and application of traditional light steel frame walls. In addition, the traditional light steel frame truss beam system, corrugated steel plate reinforced concrete floor, and roof height are large, and the traditional light steel frame wall panels have insufficient vertical load-bearing capacity, which seriously affects the net height of the floor building. In addition, the current structural wall panels lack fire extinguishing capabilities. When a fire occurs indoors, it is impossible to prevent the fire from spreading. After the fire spreads to the wall, the wall temperature rises sharply, which will cause damage to the wall structure. Summary of the invention

[0003] In order to overcome the shortcomings of the current structural wall panels that lack fire extinguishing capability and cannot prevent the spread of fire when a fire occurs indoors, the present invention provides an assembled light steel composite wall panel.

[0004] The technical implementation scheme of the present invention is: an assembled light steel composite wall panel, including a wall panel; also including an outer steel pipe, a steel plate, a pipe cover, a heat conducting plate, an inner steel pipe and an energy storage component; a plurality of outer steel pipes are fixedly connected in the wall panel, and all the outer steel pipes are arranged in a rectangular array; a steel plate is fixedly connected to the front of each outer steel pipe; each steel plate is fixed to the wall panel, and the front side of each steel plate is flush with the wall panel; a pipe cover is clamped with a flange in front of each outer steel pipe, and the pipe cover is made of rubber material, and the front side of the pipe cover is flush with the front side of the steel plate; an inner steel pipe is slidably connected in each outer steel pipe, and the outer side of the inner steel pipe fits the inner side of the outer steel pipe; each inner steel pipe is filled with expanding fireproof sand; a plurality of heat conducting plates are fixedly connected in each inner steel pipe at equal distances; each inner steel pipe is connected to an energy storage component, and the energy storage component is used to store energy in the expanding fireproof sand at the rear of the inner steel pipe.

[0005] In addition, it is particularly preferred that the energy storage assembly includes a separation plate and a clamping rod; each inner steel tube is slidably connected to a separation plate, and the separation plate is set to a rubber material; each separation plate is slidably connected to a number of heat conduction plates; a number of clamping rods are equidistantly fixed in the inner steel tube; the front side of each separation plate is in contact with a number of clamping rods.

[0006] Furthermore, it is particularly preferred that a plurality of rectangular grooves are formed at equal intervals on the front side of each steel disc.

[0007] Furthermore, it is particularly preferred that the front side of the front flange of the outer steel pipe is beveled.

[0008] Furthermore, it is particularly preferred that a gas hole is respectively opened at the rear portion of each outer steel tube.

[0009] Furthermore, it is particularly preferred that the pore walls are configured in a conical shape.

[0010] In addition, it is particularly preferred that a slot is opened in the middle of the rear side of each pipe cover, and the front part of each inner steel pipe is located in the slot on the rear side of the corresponding pipe cover.

[0011] Furthermore, it is particularly preferred that a plurality of grooves are respectively formed on the front portion of each heat conducting plate.

[0012] Furthermore, it is particularly preferred that the rear portion of the inner steel pipe is beveled.

[0013] In addition, it is particularly preferred that a connecting rod is further included; a connecting rod is fixedly connected to the front side of each partition plate; and the connecting rod is slidably connected to the heat conducting plate.

[0014] The beneficial effects of the present invention are as follows: 1. When a fire occurs indoors, the steel plate will be heated and transfer the heat to the outer steel pipe, and the outer steel pipe will heat the fireproof sand inside it through the inner steel pipe and the heat conduction plate. The expanding fireproof sand is composed of expanding microspheres and flame retardants. The expanding fireproof sand will expand when heated and accumulate expansion potential energy in the inner steel pipe. After the potential energy reaches a certain value, the pipe cover will be flushed off, and then the accumulated expansion potential energy will be released at one time, thereby throwing the flame retardant to the fire scene to play a role in fire extinguishing and fire prevention; the internal fireproof sand can be directly heated by the heat conduction plate, avoiding heating the fireproof sand only by the inner wall of the inner steel pipe, resulting in the fireproof sand in the middle of the inner steel pipe being heated slowly, and the time for the microspheres in the middle to be heated and expanded lags behind the microspheres close to the inner wall of the inner steel pipe, resulting in a prolonged response time of the entire system, affecting the fire extinguishing efficiency.

[0015] 2. The present invention provides a separation plate in the middle of the inner steel pipe, and the separation plate separates the fireproof sand in the inner steel pipe into two parts, the front part and the rear part. When the fireproof sand in the front part of the outer steel pipe is heated to wash off the pipe cover and sprinkle the flame retardant to the fire scene, the fireproof sand in the rear part of the inner steel pipe is still blocked by the separation plate. In this way, the fireproof sand in the rear part of the inner steel pipe can accumulate expansion potential energy after being heated. When the potential energy reaches a certain value, the separation plate is forced to deform through the clamping rod and then slide out of the inner steel pipe. Then, the flame retardant can be sprinkled to the fire scene to play a role in fire extinguishing and fire prevention. In this way, the fireproof sand in the rear part of the inner steel pipe can also be sprinkled very far, thereby improving the fire extinguishing and fire prevention effect.

[0016] 3. When the separator plate slides out of the inner steel tube, the separator plate will slide on the heat conduction plate. At this time, the heat conduction plate is used as a guide plate to guide and restrict the separator plate to prevent the separator plate from drastic deformation, so that the separator plate can slide out of the inner steel tube smoothly, avoiding the separator plate from being skewed and stuck during the sliding out of the inner steel tube, thereby hindering the spraying of the flame retardant.

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 creative work are within the scope of protection of the present invention. Example 1

[0029] An assembled light steel composite wall panel, such as Figure 1-7 As shown, it includes a wall panel 1;

[0030] It also includes an outer steel pipe 2, a steel plate 3, a pipe cover 4, a heat conducting plate 5, an inner steel pipe 6 and an energy storage component; a plurality of outer steel pipes 2 are fixedly connected to the wall panel 1, and all the outer steel pipes 2 are arranged in a rectangular array; a steel plate 3 is fixedly connected to the front of each outer steel pipe 2; each steel plate 3 is fixedly connected to the wall panel 1, and the front side of each steel plate 3 is flush with the wall panel 1; a pipe cover 4 is clamped to the front of each outer steel pipe 2 through a flange, and the pipe cover 4 is made of rubber, and the front side of the pipe cover 4 is flush with the steel plate 1. The front side of the disk 3 is flush; an inner steel tube 6 is slidably connected to each outer steel tube 2, and the outer side of the inner steel tube 6 fits the inner side of the outer steel tube 2; each inner steel tube 6 is filled with expanding fireproof sand, which is composed of expanding microspheres and flame retardants, and the expanding microspheres will expand when heated; four heat conduction plates 5 are equidistantly welded in each inner steel tube 6; each inner steel tube 6 is connected to an energy storage component, which is used to store energy in the expanding fireproof sand at the rear of the inner steel tube 6.

[0031] The energy storage assembly includes a separation plate 21 and a clamping rod 22; each inner steel tube 6 is slidably connected with a separation plate 21, and the separation plate 21 is set to a rubber material; each separation plate 21 is slidably connected with four heat conducting plates 5; four clamping rods 22 are equidistantly welded in the inner steel tube 6; the front side of each separation plate 21 is in contact with the four clamping rods 22.

[0032] In order to increase the heating area, six rectangular grooves are equidistantly formed on the front side of each steel plate 3 .

[0033] In order to facilitate manual covering of the pipe cover 4 on the front flange of the outer steel pipe 2, an oblique angle is provided on the front side of the front flange of the outer steel pipe 2.

[0034] In order to facilitate manual pulling of the inner steel tube 6 from the outer steel tube 2 , an air hole 2 a is respectively opened at the rear portion of each outer steel tube 2 .

[0035] In order to prevent outdoor rainwater from gathering and remaining in the air hole 2a, the wall of the air hole 2a is set to be tapered.

[0036] In order to facilitate sealing of the inner steel tube 6 , a slot is respectively opened in the middle of the rear side of each tube cover 4 , and the front part of each inner steel tube 6 is respectively located in the slot on the rear side of the corresponding tube cover 4 .

[0037] In order to increase the friction between the fingers and the heat conducting plate 5 and facilitate pulling the heat conducting plate 5 and the inner steel tube 6 out of the outer steel tube 2 , a plurality of grooves are respectively formed at the front of each heat conducting plate 5 .

[0038] In order to facilitate the insertion of the inner steel tube 6 into the outer steel tube 2 , the rear portion of the inner steel tube 6 is provided with an angled shape.

[0039] After the wall panel 1 is installed at the designated location, the front side of the wall panel 1 faces the interior. Figure 1 The position of the middle steel plate 3 is the reference, the position of the steel plate 3 is the front side, and the rear side of the wall panel 1 faces the outside. When a fire occurs indoors, the steel plate 3 will be heated and transfer the heat to the outer steel pipe 2. The outer steel pipe 2 then heats the fireproof sand inside it through the inner steel pipe 6 and the heat conducting plate 5. The expanding fireproof sand is composed of expanding microspheres and flame retardants. The expanding fireproof sand will expand when heated and accumulate expansion potential energy in the inner steel pipe 6. After the potential energy reaches a certain value, the pipe cover 4 will be flushed away, and then the accumulated expansion potential energy will be released at one time, thereby throwing the flame retardant to the fire scene to play a role in fire extinguishing and fire prevention; the internal fireproof sand can be directly heated by the heat conducting plate 5 to avoid heating the fireproof sand only by the inner wall of the inner steel pipe 6, resulting in the fireproof sand in the middle of the inner steel pipe 6 being heated slowly, and the time for the microspheres in the middle to be heated and expanded lags behind the microspheres close to the inner wall of the inner steel pipe 6, resulting in a prolonged response time of the entire system and affecting the fire extinguishing efficiency.

[0040] When a fire occurs indoors, the steel plate 3 will be heated and transfer the heat to the outer steel pipe 2, and the outer steel pipe 2 will then heat the fireproof sand inside it through the inner steel pipe 6 and the heat conducting plate 5. In this process, the heat is gradually transferred from front to back on the outer steel pipe 2, causing the fireproof sand in the front of the inner steel pipe 6 to heat faster. The fireproof sand in the front is first heated and expanded to accumulate expansion potential energy to wash away the pipe cover 4, and release the flame retardant to the fire scene, while the fireproof sand in the rear of the inner steel pipe 6 is heated and expanded and ejected. In this process, without the obstruction of the pipe cover 4, the expansion potential cannot be accumulated, resulting in the inability to throw the flame retardant very far, and the fire extinguishing and fire prevention effect is low. Therefore, in the inner steel pipe A partition plate 21 is provided in the middle of 6, and the partition plate 21 divides the fireproof sand in the inner steel pipe 6 into two parts, the front part and the rear part. When the fireproof sand in the front part of the outer steel pipe 2 is heated to wash away the pipe cover 4, and the flame retardant is thrown to the fire scene, the fireproof sand in the rear part of the inner steel pipe 6 is still blocked by the partition plate 21. In this way, the fireproof sand in the rear part of the inner steel pipe 6 can accumulate expansion potential energy after being heated. When the potential energy reaches a certain value, the partition plate 21 is forced to deform through the clamping rod 22, and then slide out of the inner steel pipe 6, and then the flame retardant can be thrown to the fire scene to play a role in fire extinguishing and fire prevention. In this way, the fireproof sand in the rear part of the inner steel pipe 6 can also be thrown very far, thereby improving the fire extinguishing and fire prevention effect.

[0041] The thrusts from the fireproof sand at different places on the rear side of the separator plate 21 are different, which causes the separator plate 21 to tilt and get stuck when it slides out of the inner steel pipe 6, thereby hindering the flame retardant from spraying out; when the separator plate 21 slides out of the inner steel pipe 6, the separator plate 21 will slide on the heat conducting plate 5, and at this time the heat conducting plate 5 is used as a guide plate, which guides and restricts the separator plate 21 through the heat conducting plate 5 to prevent the separator plate 21 from drastic deformation, so that the separator plate 21 can slide out of the inner steel pipe 6 smoothly, thereby preventing the separator plate 21 from tilting and getting stuck during the sliding out of the inner steel pipe 6, thereby hindering the flame retardant from spraying out.

[0042] When a fire occurs, after the fireproof sand in the inner steel tube 6 is sprayed out, and after the fire is over, the fireproof sand can be refilled into the inner steel tube 6, and then the tube cover 4 can be snapped back into the outer steel tube 2 for reuse; however, the inner steel tube 6 is in a horizontal state, which is not conducive to filling the inner steel tube 6 with fireproof sand, and the obstruction of the heat conducting plate 5 makes the filling operation more difficult. In order to facilitate the filling of the fireproof sand into the inner steel tube 6, the front part of the heat conducting plate 5 can be manually pinched, and the heat conducting plate 5 and the inner steel tube 6 can be pulled out of the outer steel tube 2. Since the outer side surface of the inner steel tube 6 and the inner side surface of the outer steel tube 2 are in contact, when the inner steel tube 6 is pulled out of the outer steel tube 2, a negative pressure will be generated between the inner steel tube 6 and the outer steel tube 2, and a lot of manual effort is required to pull the inner steel tube 6 out of the outer steel tube 2. Therefore, an air hole 2a is opened at the rear part of the outer steel pipe 2, so that when the inner steel pipe 6 is pulled out from the outer steel pipe 2, the outside air will enter the outer steel pipe 2 through the air hole 2a, thereby avoiding the generation of negative pressure between the inner steel pipe 6 and the outer steel pipe 2, so as to facilitate the manual pulling of the inner steel pipe 6 from the outer steel pipe 2. After the inner steel pipe 6 is pulled out from the outer steel pipe 2, the inner steel pipe 6 is manually erected, and then the fireproof sand is filled into the inner steel pipe 6. After filling, the pipe cover 4 is covered on the inner steel pipe 6, and the upper part of the inner steel pipe 6 is stuck in the card groove in the middle part of the pipe cover 4. In this way, the inner steel pipe 6 is sealed to prevent the fireproof sand from falling. Then the inner steel pipe 6 is inserted into the outer steel pipe 2. At this time, the air in the outer steel pipe 2 is discharged through the air hole 2a, and the pipe cover 4 is re-stuck on the outer steel pipe 2. Example 2

[0043] On the basis of Example 1, Figure 7 As shown, a connecting rod 23 is also included; a connecting rod 23 is welded to the front side of each partition plate 21; and the connecting rod 23 is slidably connected to the heat conducting plate 5.

[0044] When refilling the inner steel pipe 6 with fireproof sand, when the fireproof sand is close to the clamping rod 22, stop filling, then manually hold the connecting rod 23, and then insert the connecting rod 23 and the partition plate 21 into the inner steel pipe 6, so that the partition plate 21 is deformed and passes through the clamping rod 22, and then fill the inner steel pipe 6 with fireproof sand. At this time, the connecting rod 23 is set to facilitate manual installation of the partition plate 21 back to its original position; in addition, the connecting rod 23 is slidably connected to the heat conducting plate 5, and the connecting rod 23 is restricted by the heat conducting plate 5. When the partition plate 21 is removed from the inner steel pipe 6, the separating plate 21 will synchronously push the connecting rod 23 to slide under the restriction of the heat conducting plate 5, and since the connecting rod 23 is restricted by the heat conducting plate 5, the connecting rod 23 will only come out horizontally when it is ejected from the inner steel tube 6, that is, the connecting rod 23 will slide out of the inner steel tube 6 with the separating plate 21 horizontally, and then the separating plate 21 will be restricted and guided by the connecting rod 23, so that the separating plate 21 can slide out of the inner steel tube 6 smoothly, avoiding the separating plate 21 from being skewed and stuck during the sliding out of the inner steel tube 6, thereby hindering the spraying of the flame retardant.

[0045] like Figure 8-Figure 10 As shown, the structure of the wall panel 1 is, from front to back, 10mm hardened mortar plastering, 50mm graphite polystyrene board insulation layer, 30mm wire mesh light concrete outer leaf, 90mm light steel truss light concrete surface layer (with hidden steel tube concrete hidden column and C-type light steel keel), 25mm wire mesh light concrete inner leaf and 5mm inner rolled alkali-resistant glass fiber mesh anti-cracking mortar surface layer, and the total thickness of the wall panel 1 is 210mm; the wall panel 1 is a new type of structural exterior wall, that is, steel tube concrete columns and steel tube ring beams are used to strengthen the constraints on the exterior wall panel 1 to form a reinforced exterior wall, which significantly improves the horizontal seismic bearing capacity and significantly improves the vertical bearing capacity; the new type of structural exterior wall is simpler in structure than the traditional cold-bent thin-walled steel wall panel 1, and overcomes the disadvantage of hollow drum sound when knocked.

[0046] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea.
