Description

Technical Field

[0001] The utility model relates to the technical field of building exterior walls, in particular to a fireproof building exterior wall. Background Art

[0002] When the insulation material on the exterior wall of a building catches fire, the fire will spread rapidly through combustion, heat radiation, and flying fire due to the influence of combined factors such as high-altitude wind and the microclimate of the fire scene.

[0003] In order to improve the fire resistance of building exterior walls and slow down the spread of fire, fire protection technology has been developed.

[0004] For example, in the patent with the publication number CN204609022U, a "exterior wall fire protection and thermal insulation system" is disclosed, see Figure 1 The patent includes an insulation board 1 and a fireproof connector 2. The fireproof connector 2 is arranged at intervals on the outer surface of the outer wall 3. The insulation board 1 includes an outer wall insulation board 11 and a filling insulation board 12. The outer wall insulation board 11 is embedded between two adjacent upper and lower fireproof connectors 2, and the filling insulation board 12 is filled in the interior of the fireproof connector 2.

[0005] The working principle of the above patent is that the fireproof connector 2 separates the exterior wall insulation board 11 to avoid a large-scale fire, plays a role in fire isolation and fire prevention, and delays the spread of fire.

[0006] However, since the outer side surfaces of the exterior wall insulation board 11 and the fireproof connector 2 are flush, as the fire increases and the flames rise, the flames can easily spread along the surface of the fireproof connector 2 to the exterior wall insulation board 11 above, igniting the exterior wall insulation board 11 above, so that the fire prevention effect needs to be improved.

[0007] Therefore, how to improve the fire prevention effect is a technical problem that needs to be solved at present. Utility Model Content

[0008] The utility model aims at the above-mentioned deficiencies in the prior art and provides a fireproof building exterior wall. The utility model can improve the fireproof effect.

[0009] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0010] A fireproof building exterior wall comprises an insulation board and a fireproof connector. The fireproof connector is arranged at intervals on the outer side of the exterior wall. The insulation board comprises an exterior wall insulation board and a filling insulation board. The exterior wall insulation board is arranged between two adjacent upper and lower fireproof connectors. The filling insulation board is filled in the interior of the fireproof connector. A slot is provided on the upper outer side of the fireproof connector. A fireproof plug-in plate is horizontally inserted in the slot. The fireproof plug-in plate is connected to the bottom of the slot through a first elastic member. The fireproof plug-in plate is connected to one end of a connecting rope. The other end of the connecting rope is buried in the interior of the exterior wall insulation board below the fireproof connector.

[0011] Furthermore, the fireproof connecting piece includes a top plate, a connecting plate, a bottom plate, and a connecting column. The top plate is connected to the upper end of the connecting plate at the end away from the outer wall, and the lower end of the connecting plate is connected to the end of the bottom plate away from the outer wall. The top plate, the connecting plate, the bottom plate and the outer wall surround to form a accommodating cavity, and the filling insulation board is arranged in the accommodating cavity. The top plate is connected to the upper end of the connecting column at the end close to the outer wall, and the lower end of the connecting column is connected to the end of the bottom plate close to the outer wall. The top plate is provided with the slot, and the lower slot wall of the slot is provided with a rope threading hole, which passes downward through the connecting column and the bottom plate, and the connecting rope is arranged in the rope threading hole.

[0012] Furthermore, the top plate is bent upward to form a first folded edge at one end close to the outer wall, and the bottom plate is bent downward to form a second folded edge at one end close to the outer wall, and both the first folded edge and the second folded edge are connected to the outer wall through anchor bolts.

[0013] Furthermore, the exterior wall insulation board is connected to the exterior wall via insulation nails.

[0014] Furthermore, a flip groove is provided on the top surface of the fireproof plug plate, and a fireproof flap is provided in the flip groove. The fireproof flap is rotatably connected to the groove wall of the flip groove through a rotating shaft at the end away from the outer wall. A second elastic member is provided on the flip groove, and the second elastic member is used to bounce the fireproof flap upward.

[0015] Furthermore, a hidden groove is provided on the lower groove wall of the flip groove, and the second elastic member is provided in the hidden groove.

[0016] The utility model has the beneficial effects:

[0017] 1. When a certain external wall insulation board catches fire, the connecting rope inside the external wall insulation board will also burn. When the part of the connecting rope located inside the external wall insulation board is burned out, the connecting rope no longer pulls the fireproof plug plate. The elastic force of the first elastic member pushes the fireproof plug plate out of the slot, so that the fireproof plug plate can block the flame from the horizontal direction, increasing the difficulty for the flame to contact the external wall insulation board above. The connecting plate in the fireproof connector blocks the flame from the vertical direction. Compared with the background technology that only blocks the flame from the vertical direction, the fireproof effect is improved.

[0018] 2. As long as the external wall insulation board is burning, the connecting rope inside the external wall insulation board will be burned, and the fireproof plug board can be extended horizontally out of the slot without the need for manual operation by workers, which can respond in time and help improve emergency response capabilities.

[0019] 3. When a certain external wall insulation board catches fire, the connecting rope inside the external wall insulation board will burn, and the connecting rope will lose its pulling effect on the fireproof plug board. The elastic force of the first elastic member will push the fireproof plug board out of the slot. When the fireproof plug board extends from the slot, the flip groove on the top surface of the fireproof plug board and the fireproof flap in the flip groove are exposed. There is no obstruction above the fireproof flap, and the fireproof flap can be bounced upward under the elastic force of the second elastic member. At this time, the fireproof plug board can block the flames from the horizontal direction, and the fireproof flap further expands the blocking range of the fireproof plug board, further improving the fireproof effect.

[0020] 4. By arranging the second elastic member in the hidden groove, the second elastic member can be prevented from occupying the space in the flip groove, which is beneficial to reducing the depth of the flip groove, and then conveniently reducing the thickness of the entire fireproof plug board, thereby saving processing consumables.

[0040] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings. It is worth noting that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] Example:

[0042] See also Figure 2-Figure 11 A fireproof building exterior wall comprises an insulation board 1 and a fireproof connector 2.

[0043] The fireproof connecting pieces 2 are arranged at intervals on the outer side of the outer wall 3 .

[0044] The fireproof connecting piece 2 includes a top plate 21 , a connecting plate 22 , a bottom plate 23 , and a connecting column 24 .

[0045] The top plate 21 is welded to the upper end of the connecting plate 22 at the end away from the outer wall 3, and the lower end of the connecting plate 22 is welded to the end of the bottom plate 23 away from the outer wall 3, so that the top plate 21, the connecting plate 22, the bottom plate 23 and the outer wall 3 surround to form a accommodating cavity.

[0046] The top plate 21 is welded and fixed to the upper end of the connecting column 24 at one end close to the outer wall 3 , and the lower end of the connecting column 24 is welded and fixed to the end of the bottom plate 23 close to the outer wall 3 .

[0047] The top plate 21 is provided with a slot 211 on a side facing away from the outer wall 3 , and a rope threading hole 212 is provided on a lower slot wall of the slot 211 , and the rope threading hole 212 passes through the connecting column 24 and the bottom plate 23 downward.

[0048] The top plate 21 is bent upward to form a first folded edge 213 at one end close to the outer wall 3 , and the bottom plate 23 is bent downward to form a second folded edge 231 at one end close to the outer wall 3 . Both the first folded edge 213 and the second folded edge 231 are fixed to the outer wall 3 by anchor bolts 25 .

[0049] The insulation board 1 includes an external wall insulation board 11 and a filling insulation board 12. The external wall insulation board 11 is arranged between two adjacent upper and lower fireproof connectors 2, and the external wall insulation board 11 is fixed to the external wall 3 by insulation nails 111. The filling insulation board 12 is filled in the accommodating cavity.

[0050] A fireproof plugboard 4 is horizontally inserted into the slot 211 .

[0051] The fireproof plug plate 4 is connected to the bottom of the slot 211 through the first elastic member 5 at one end close to the outer wall 3. The first elastic member 5 can be a spring. One end of the spring is welded and fixed to the fireproof plug plate 4, and the other end of the spring is welded and fixed to the bottom of the slot 211. The first elastic member 5 is used to push the fireproof plug plate 4 out of the slot 211.

[0052] A connecting rope 6 is tied to one end of the fireproof plug plate 4 close to the outer wall 3, and the other end of the connecting rope 6 continues to extend downward after passing through the rope hole 212. After passing through the rope hole 212, the connecting rope 6 is buried inside the outer wall insulation board 11 under the fireproof connector 2.

[0053] The working principle of this embodiment is:

[0054] When no fire occurs, the connecting rope 6 overcomes the elastic force of the first elastic member 5 and pulls the fireproof plug plate 4, so that the fireproof plug plate 4 is accommodated in the slot 211, and the first elastic member 5 is in a compressed energy storage state.

[0055] When an exterior wall insulation board 11 catches fire, the connecting rope 6 located inside the exterior wall insulation board 11 also burns. When the part of the connecting rope 6 located inside the exterior wall insulation board 11 is burned out, the connecting rope 6 no longer pulls the fireproof plug board 4. The elastic force of the first elastic member 5 pushes the fireproof plug board 4 out of the slot 211, so that the fireproof plug board 4 can block the flames from the horizontal direction, increasing the difficulty for the flames to contact the exterior wall insulation board 11 above. The connecting plate 22 in the fireproof connector 2 blocks the flames from the vertical direction. Compared with the background technology that only blocks the flames from the vertical direction, the fireproofing effect is improved.

[0056] Furthermore, from the above introduction, it can be seen that as long as the external wall insulation board 11 is burning, the connecting rope 6 inside the external wall insulation board 11 will be burned, and the fireproof plug board 4 can be horizontally extended out of the slot 211 without the need for manual operation by workers, and timely response can be achieved, which is conducive to improving emergency response capabilities.

[0057] Embodiment 2:

[0058] This embodiment 2 is further improved on the basis of embodiment 1:

[0059] See also Fig.12 A flip groove 41 is provided on the top surface of the fireproof plug plate 4, and a fireproof flap 411 is provided in the flip groove 41. The fireproof flap 411 is rotatably connected to the groove wall of the flip groove 41 through a rotating shaft 412 at the end away from the outer wall 3. A hidden groove 413 is provided on the lower groove wall of the flip groove 41. A second elastic member 414 is provided in the hidden groove 413. The second elastic member 414 can also be a spring. The lower end of this spring is welded and fixed to the bottom of the hidden groove 413. The upper end of this spring abuts against the bottom surface of the fireproof flap 411. The second elastic member 414 is used to bounce the fireproof flap 411 upward.

[0060] When no fire occurs, the connecting rope 6 overcomes the elastic force of the first elastic member 5 to pull the fireproof plug plate 4 so that the fireproof plug plate 4 is accommodated in the slot 211, and the fireproof flap 411 on the top surface of the fireproof plug plate 4 is pressed by the upper slot wall of the slot 211, and the second elastic member 414 is in a compressed energy storage state.

[0061] When a certain external wall insulation board 11 catches fire, the connecting rope 6 located inside the external wall insulation board 11 will burn, and the connecting rope 6 will lose the pulling effect with the fireproof plug board 4. The elastic force of the first elastic member 5 will push the fireproof plug board 4 out of the slot 211. When the fireproof plug board 4 extends from the slot 211, the flip groove 41 on the top surface of the fireproof plug board 4 and the fireproof flap 411 in the flip groove 41 are exposed. There is no obstruction above the fireproof flap 411, and the fireproof flap 411 can be bounced upward under the elastic force of the second elastic member 414. At this time, the fireproof plug board 4 can block the flames from the horizontal direction, and the fireproof flap 411 further expands the blocking range of the fireproof plug board 4, further improving the fire blocking and fire prevention effect.

[0062] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
