The thermal insulation wall comprises a structural wall body, a thermal insulation wallboard, a thermosensitive trigger assembly and a connecting assembly. The heat preservation wallboard is fixed to the structural wall through the connecting assembly, the thermosensitive trigger assembly controls the connecting assembly, and when the environment temperature exceeds a set value, the thermosensitive trigger assembly judges that a fire happens on site, and the thermosensitive trigger assembly triggers the connecting assembly to enable the heat preservation wallboard to be separated from the structural wall. The thermal insulation wallboard is made of flame-retardant materials and can resist fire for a certain time, in addition, compared with a traditional fixed thermal insulation wall, due to the fact that the thermal insulation wallboard is separated from the structural wall body, the influence of the fire on the structural wall body is reduced in the time period of fire resistance and final failure combustion of the thermal insulation wallboard, and the thermal insulation effect is improved. The fire resisting time of the whole thermal insulation wall is greatly prolonged, and the flame retardant effect is better.

Description

Technical Field

[0001] The invention relates to the field of construction, and in particular to a thermal insulation wall with a flame retardant function. Background Art

[0002] An insulation wall is a wall that has a stronger ability to insulate heat transfer than an ordinary wall. It is often used in cold areas and some occasions that require special insulation. In the prior art, the basic structure of an insulation wall is to install an insulation layer on the structural wall, and sometimes other additional materials such as a reinforcement layer and a decorative layer are configured as needed. When facing fire protection design requirements, the insulation walls in the prior art are all based on the material perspective, and flame-retardant materials are selected as much as possible to make the insulation layer, so that the entire insulation wall has a certain flame retardant ability. However, the flame retardant ability of flame retardant materials has an upper limit. When facing a fire, the insulation layer in the prior art can only withstand a certain period of time, and the safety performance is limited. Summary of the invention

[0003] The technical problem to be solved by the present invention is that the thermal insulation wall of the prior art only relies on flame retardant materials to achieve the fire protection function, and the flame retardant performance is limited.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: an insulation wall with flame retardant function, including a structural wall, an insulation wall panel, a thermal trigger component and a connection component.

[0005] The thermal insulation wall panel is fixed to the structural wall through a connecting component, and the thermal trigger component controls the connecting component. When the ambient temperature exceeds a set value, the thermal trigger component determines that a fire has occurred on site, and the thermal trigger component triggers the connecting component to separate the thermal insulation wall panel from the structural wall.

[0006] The insulation wall panels themselves are made of flame-retardant materials and can resist fire for a certain period of time. In addition, compared with traditional fixed insulation walls, since the insulation wall panels of the present invention are separated from the structural walls, the impact of the fire on the structural walls is reduced during the period when the insulation wall panels resist fire and eventually fail to burn, so that the entire insulation wall of the present invention can resist fire for a greatly extended time and has a better flame retardant effect.

[0007] Specifically, the connecting assembly includes a base, an outer tube, a bolt, a first spring, a lock tongue plate and a plate pulling mechanism, the bolt fixes the base to the structural wall, the outer tube is sleeved on the base, and an opening is provided on the outer tube to facilitate the entry of tools into the outer tube to rotate the bolt; the first spring is compressed between the outer tube and the base, and the lock tongue plate is radially inserted into the outer tube so that the outer tube is stuck on the base, ensuring that the first spring is in a compressed and force-accumulating state; the outer tube is connected to the insulation wall panel; the plate pulling mechanism is used to pull out the lock tongue plate, and the plate pulling mechanism is controlled by a thermal trigger assembly.

[0008] When the thermal trigger component detects a fire, the plate pulling mechanism pulls out the lock tongue plate, and the first spring with stored force will pop out of the outer tube, and the thermal insulation wall panel connected to the outer tube will also pop out together, so that in the early stage of the fire, the thermal insulation wall panel is immediately separated from the structural wall, delaying the time when the fire source contacts the structural wall, thereby achieving the purpose of flame retardancy.

[0009] Specifically, the plate pulling mechanism includes a turntable, a force-storage torsion spring and a bayonet. The turntable is concentric with the outer cylinder. The force-storage torsion spring is sleeved on the outer cylinder and connected to the turntable. The force-storage torsion spring is used to drive the turntable to rotate. After the force is twisted and stored, the bayonet is inserted from the outer ring edge plate on the surface of the outer cylinder and clamps the turntable. The bayonet is controlled by a thermal trigger component; a circular shaft is provided on the surface of the turntable, an inclined groove is provided on the lock tongue plate, and the circular shaft is inserted into the inclined groove; a movable groove along the radial direction of the outer cylinder is provided in the thermal insulation wall panel, and the lock tongue plate is in the movable groove.

[0010] When the thermal trigger assembly detects a fire, the thermal trigger assembly pulls out the latch pin, and the force-storage torsion spring drives the turntable to rotate. The turntable uses the circular shaft and the inclined groove to drive the lock tongue plate to translate in the moving groove, thereby realizing the pulling-out action of the lock tongue plate.

[0011] Furthermore, a connecting rope is provided in the outer tube, and the two ends of the connecting rope are respectively connected to the outer tube and the base; the function of the connecting rope is: after a fire occurs, the outer tube and the insulation wall panel are ejected, but the insulation wall panel will still be hung on the structural wall by the connecting rope of appropriate length, which is beneficial for the insulation wall panel to shield the fire source for the structural wall on the one hand, and can also prevent the insulation wall panel from directly falling and injuring people who are escaping on the other hand.

[0012] Furthermore, the thermal trigger assembly includes a thermal trigger and a pull rope assembly, the thermal trigger includes a sliding plate, a second spring and a thermistor, the sliding plate is L-shaped and there are two of them, the sliding plate is provided with a sliding rail and a sliding groove, the sliding grooves of the two sliding plates are respectively inserted into each other's sliding rails, the thermistor and the second spring are both located between the two sliding plates, the second spring is in an elongated state, and the thermistor is supported between the two sliding plates; the sliding plate is connected to the bayonet through the pull rope assembly.

[0013] Thermistors are products widely used in the field of fire protection, mainly including a glass shell and a thermal liquid enclosed inside the glass shell. When a fire occurs, the ambient temperature rises, and the thermal liquid expands due to the heat and breaks the glass shell, causing the entire thermistor to break. After losing the support of the thermistor, the two sliding plates will move closer to each other under the action of the second spring, and the sliding plates will pull the pull rope assembly during the translation process.

[0014] Furthermore, there are multiple thermal triggers; the pull rope assembly includes a first pull rope, a second pull rope and a pull rod, one end of the pull rod is provided with a through hole and the other end is connected to the second pull rope, and the second pull rope is connected to the pin; the first pull rope passes through the through hole, and the two ends of the first pull rope are respectively connected to the sliding plates of two adjacent thermal triggers.

[0015] When a fire occurs, the thermistor is broken, and the sliding plate moves horizontally to first pull the first pull rope, and then the first pull rope drives the pull rod and the second pull rope to move horizontally, and the second pull rope pulls out the bayonet.

[0016] Specifically, the thermal insulation wall panel is a multi-layer structure, generally including multiple or all of a composite board layer, a thermal insulation layer, a fixing layer, a reinforcement board layer and a decorative layer.

[0017] Furthermore, the thermal insulation wall of the present invention further comprises a sprayer, which is installed on the surface of the structural wall; the sprayer comprises an outer shell, a fire extinguishing agent and a thermal sensitive liquid, and a partition is arranged inside the outer shell, which separates an inner cavity and an outer ring cavity inside the outer shell, wherein the fire extinguishing agent is placed in the inner cavity and the thermal sensitive liquid is filled in the outer ring cavity. After a fire occurs, the thermal sensitive liquid expands due to heat and breaks the outer shell, so that the internal fire extinguishing agent is sprayed out, achieving the effect of fire extinguishing or flame retardancy.

[0018] Beneficial effects: (1) The thermal insulation wall with flame retardant function of the present invention utilizes a thermal trigger component and a connection component to realize the automatic separation of the thermal insulation wall panel and the structural wall when a fire occurs, delaying the time when the fire source contacts the structural wall, and improving the flame retardant effect of the entire thermal insulation wall. (2) The thermal insulation wall with flame retardant function of the present invention integrates the various components in the connection component inside and outside the outer tube, and has a delicate structure; the entire connection component is pre-set in the thermal insulation wall panel in advance, so that the thermal insulation wall panel of the present invention is almost the same as the installation process of the traditional thermal insulation wall panel, without adding any additional installation cost. (3) The thermal insulation wall with flame retardant function of the present invention is equipped with a connecting rope in the outer tube, and the thermal insulation wall that pops up after a fire occurs will be hung on the structural wall, which is beneficial for the thermal insulation wall panel to shield the fire source for the structural wall on the one hand, and can also prevent the thermal insulation wall panel from directly falling and injuring people who are escaping on the other hand. (4) The thermal insulation wall with flame retardant function of the present invention is equipped with a sprinkler on the structural wall, and the sprinkler automatically sprays out the fire extinguishing agent after a fire occurs, further improving the flame retardant ability of the thermal insulation wall.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with specific implementation modes.

[0031] Example 1

[0032] like Figures 1 to 4 As shown, the thermal insulation wall with flame retardant function of this embodiment includes a structural wall 100, a thermal insulation wall panel 200, a thermal trigger component 300, a connection component 400 and a sprayer 500.

[0033] The insulation wall panel 200 is fixed to the structural wall 100 through the connecting component 400. The thermal trigger component 300 controls the connecting component 400. When the ambient temperature exceeds the set value, the thermal trigger component 300 determines that a fire has occurred at the scene. The thermal trigger component 300 triggers the connecting component 400 to separate the insulation wall panel 200 from the structural wall 100.

[0034] like Figures 5 to 7 As shown, the connection assembly 400 includes a base 410, an outer cylinder 420, a bolt 430, a first spring 440, a locking tongue plate 450 and a plate pulling mechanism. The bolt 430 is a hexagon socket bolt. The bolt 430 fixes the base 410 to the structural wall 100. The outer cylinder 420 is sleeved on the base 410. An opening is provided on the outer cylinder 420 to facilitate the entry of a tool into the outer cylinder 420 to rotate the bolt 430; the first spring 440 is compressed between the outer cylinder 420 and the base 410, and the locking tongue plate 450 is radially inserted into the outer cylinder 420 so that the outer cylinder 420 is stuck on the base 410, ensuring that the first spring 440 is in a compressed and stored state; the outer cylinder 420 is connected to the thermal insulation wall panel 200; the plate pulling mechanism is used to pull out the locking tongue plate 450, and the plate pulling mechanism is controlled by the thermal trigger assembly 300. When the thermal trigger assembly 300 detects a fire, the plate pulling mechanism pulls out the lock tongue plate 450, and the first spring 440 with stored force will pop out of the outer tube 420, and the thermal insulation wall panel 200 connected to the outer tube 420 will also pop out together, so that at the early stage of the fire, the thermal insulation wall panel 200 is immediately separated from the structural wall 100, delaying the time when the fire source contacts the structural wall 100, thereby achieving the purpose of flame retardancy.

[0035] The plate pulling mechanism includes a rotating disk 460, a force storage torsion spring 470 and a bayonet 480. The rotating disk 460 is concentric with the outer cylinder 420. The force storage torsion spring 470 is sleeved on the outer cylinder 420 and connected to the rotating disk 460. The force storage torsion spring 470 is used to drive the rotating disk 460 to rotate. After the force storage and twisting, the bayonet 480 is inserted from the outer ring edge plate on the surface of the outer cylinder 420 and clamps the rotating disk 460. The bayonet 480 is controlled by the thermal trigger assembly 300; Figure 8 As shown, the surface of the rotating disk 460 is provided with a circular shaft 461, and the locking tongue plate 450 is provided with an inclined groove 451, and the circular shaft 461 is inserted into the inclined groove 451; the thermal insulation wall panel 200 is provided with a moving groove along the radial direction of the outer cylinder 420, and the locking tongue plate 450 is in the moving groove, ensuring that the locking tongue plate 450 can only move along the radial direction of the outer cylinder 420. When the thermal trigger component 300 detects a fire, the thermal trigger component 300 pulls out the latch 480, and the force storage torsion spring 470 drives the rotating disk 460 to rotate, as shown in FIG. Fig. 9 and Fig.10 As shown, after the rotating disk 460 rotates clockwise, the rotating disk 460 drives the locking tongue plate 450 to move along the radial direction of the outer cylinder 420 by means of the circular shaft 461 and the inclined groove 451, thereby realizing the pulling-out action of the locking tongue plate 450.

[0036] like Figure 6As shown, a connecting rope 490 is also provided in the outer cylinder 420, and the two ends of the connecting rope 490 are respectively connected to the outer cylinder 420 and the base 410; the function of the connecting rope 490 is: after a fire occurs, the outer cylinder 420 and the insulation wall panel 200 are ejected, but the insulation wall panel 200 will still be hung on the structural wall 100 by the connecting rope 490 of appropriate length, which is beneficial for the insulation wall panel 200 to shield the structural wall 100 from the fire source on the one hand, and can also prevent the insulation wall panel 200 from directly falling and injuring people who are escaping on the other hand.

[0037] like Figure 4 As shown, the thermal trigger assembly 300 includes a thermal trigger 310 and a pull rope assembly 320. The thermal trigger 310 includes a sliding plate 311, a second spring 312 and a thermal tube 313. The sliding plate 311 is L-shaped and there are two of them. The sliding plate 311 is provided with a sliding rail 311-1 and a sliding groove 311-2. The sliding grooves 311-2 of the two sliding plates 311 are respectively inserted into the sliding rails 311-1 of each other. The thermal tube 313 and the second spring 312 are both located between the two sliding plates 311. The second spring 312 is in an elongated state. The thermal tube 313 is supported between the two sliding plates 311. There are multiple thermal triggers 310.

[0038] The pull rope assembly 320 includes a first pull rope 321, a second pull rope 322 and a pull rod 323. One end of the pull rod 323 is provided with a through hole and the other end is connected to the second pull rope 322. The second pull rope 322 is connected to the pin 480. The first pull rope 321 passes through the through hole, and the two ends of the first pull rope 321 are respectively connected to the sliding plates 311 of two adjacent thermal triggers 310.

[0039] When a fire occurs, the thermistor 313 breaks. After losing the support of the thermistor 313, the two sliding plates 311 move closer to each other under the action of the second spring 312. When the sliding plate 311 moves, it first pulls the first pull rope 321, and then the first pull rope 321 drives the pull rod 323 and the second pull rope 322 to move, and the second pull rope 322 pulls out the pin 480.

[0040] The thermal insulation wall panel 200 in this embodiment is a multi-layer structure, including multiple or all of a composite board layer, a thermal insulation layer, a fixing layer, a reinforcement board layer and a decorative layer.

[0041] The sprinkler 500 is installed on the surface of the structural wall 100; the sprinkler 500 includes a shell, a fire extinguishing agent and a thermal liquid. A partition is provided inside the shell, and the partition separates an inner cavity and an outer cavity inside the shell. The inner cavity is filled with the fire extinguishing agent, and the outer cavity is filled with the thermal liquid. After a fire occurs, the thermal liquid expands due to heat and breaks the shell, so that the internal fire extinguishing agent is sprayed out to achieve the effect of fire extinguishing or flame retardancy.

[0042] The thermal insulation wall with flame retardant function in this embodiment uses the thermal trigger component 300 and the connection component 400 to realize the automatic separation of the thermal insulation wall panel 200 and the structural wall 100 when a fire occurs. The thermal insulation wall panel 200 itself is made of flame retardant material and can resist the fire for a certain period of time. Compared with the traditional fixed thermal insulation wall, the thermal insulation wall panel 200 actively separated in this embodiment delays the time when the fire source contacts the structural wall 100, so that the entire thermal insulation wall can resist the fire for a much longer time, and the flame retardant effect is better.

[0043] Although the embodiments of the present invention are described in the specification, these embodiments are only for reference and should not limit the protection scope of the present invention. Various omissions, substitutions and changes within the scope of the present invention should be included in the protection scope of the present invention.
