Description

Technical Field

[0001] The utility model relates to the field of underground garage fire wall door components, in particular to an underground garage fire wall door component and an underground garage system. Background Art

[0002] At present, in order to divide the underground garage into fire zones, fire shutters need to be installed at certain intervals, usually at the driveway. However, due to the large span at the driveway and the 1.2-1.5m covering soil on the upper part of the upper roof of the driveway, the structural load is large, so the height of the beam at the fire shutter is relatively high. The net height of the garage is generally ≥2.2m, and the water and electricity pipelines must be stretched through the basement. At present, the common approach is to arrange the water and electricity pipelines along the driveway, and at the fire shutter, the water and electricity pipelines pass under the beam at the fire shutter to avoid drilling holes in the beam, which will cause the beam to be weakened. However, this will increase the basement floor height and greatly increase the construction cost of the basement. Utility Model Content

[0003] The purpose of the utility model is to overcome the disadvantage of a high beam position at an underground garage fire door in the background art, and to provide an underground garage fire wall door assembly and an underground garage system.

[0004] In a first aspect, the utility model provides an underground garage fire wall door assembly, comprising two first columns spaced apart, a first crossbeam connected between the two first columns, a second crossbeam disposed on a side of the first column away from the first crossbeam, the first crossbeam being higher than the second crossbeam, a second column connected on a side of the second crossbeam away from the first column, a net distance L1 between the second column and an adjacent first column, a net distance L2 between adjacent first columns, and L1 < L2;

[0005] It also includes a water and electricity pipeline, which passes through the second beam from the lower part of the second beam, and the bottom height of the water and electricity pipeline is equal to or higher than the bottom height of the first beam.

[0006] The underground garage fire wall door assembly described in the present application is configured such that a first crossbeam is arranged between two of the first columns, and both the first crossbeam and the second crossbeam are supported by the first columns, so that the bottoms of the first crossbeam and the second crossbeam do not need to be at the same height. On this basis, the height of the second crossbeam is lowered by avoiding the water and electricity pipelines from the first crossbeam at the upper part of the driveway and by shortening the net distance between the second column and the adjacent first column, thereby making room for the height of the water and electricity pipelines at the lower part of the second crossbeam. Without damaging the first crossbeam and the second beam, the space requirements of the water and electricity pipelines are met without increasing the height of the basement, thereby saving construction costs.

[0007] Preferably, 3m≤L1≤4m, 5m≤L2≤7.5m.

[0008] Preferably, the top of the second crossbeam is higher than that of the first crossbeam.

[0009] On the basis of making room for water and electricity pipelines at the lower part of the second beam, by making the top of the second beam higher than the first beam, the second beam can meet better load-bearing requirements, thereby ensuring the safety of the building structure beam.

[0010] Preferably, along the length direction of the first crossbeam, the first crossbeam and the second crossbeam at least partially overlap.

[0011] Preferably, the first crossbeam and the second crossbeam are connected.

[0012] Preferably, the first crossbeam and the second crossbeam are integrally provided.

[0013] Preferably, a fire wall is provided at the lower portion of the second cross beam, and holes are provided on the fire wall, and the water and electricity pipelines pass through the holes, and the water and electricity pipelines are sealed with the holes.

[0014] Preferably, the water and electricity pipeline includes a water pipe and an electric bridge, and the water pipe is located on one side of the electric bridge.

[0015] To minimize the overall height of the water and electricity pipelines.

[0016] Preferably, the first column supports a longitudinal beam, and the longitudinal beam is perpendicular to the first transverse beam.

[0017] Preferably, the thickness of the longitudinal beam is smaller than the width of the first column.

[0018] Preferably, the water and electricity pipelines pass through the longitudinal beam from the lower part of the longitudinal beam.

[0019] Preferably, the bottom of the longitudinal beam is flush with the bottom of the second transverse beam.

[0020] Preferably, the water and electricity pipelines pass through the longitudinal beam from the lower part of the longitudinal beam so as not to affect the strength of the longitudinal beam.

[0021] In a second aspect, the utility model provides an underground garage system, comprising an underground garage fire wall door assembly as described in the present application, wherein the first beam is located above the driveway.

[0022] An underground garage system described in the present invention includes a driveway and an underground garage fire wall door assembly described in the present application. By arranging a first crossbeam between two first columns, and the first crossbeam and the second crossbeam are both supported by the first column, the bottoms of the first crossbeam and the second crossbeam do not need to be at the same height. On this basis, by avoiding the water and electricity pipelines from the first crossbeam at the upper part of the driveway and shortening the net distance between the second column and the adjacent first column, the height of the second crossbeam is lowered, thereby making room for the height of the water and electricity pipelines at the bottom of the second crossbeam. Without damaging the first crossbeam and the second beam, the space requirements of the water and electricity pipelines are met without increasing the height of the basement, thereby saving construction costs.

[0023] Preferably, two first upright columns arranged at intervals and the first crossbeam together enclose a door opening for vehicles to pass through.

[0024] Preferably, the underground garage system described in this embodiment further includes a fireproof rolling shutter door, which includes a curtain plate and a roller for retracting and extending the curtain plate, the roller is located in a roller shutter box, and the roller shutter box is located on one side of the first beam.

[0025] By setting the rolling shutter box on one side of the first crossbeam, the height occupied by the fire shutter door as a whole can be effectively reduced while meeting the minimum height of the door opening, so that the underground garage fire wall door assembly described in this application can still meet the height requirements for the installation and use of the fire shutter door while reducing the overall height of the basement.

[0026] Preferably, the top support of the underground garage fire wall door assembly is connected with a layer plate structure.

[0027] Preferably, a covering layer is provided above the layer plate structure.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The underground garage fire wall door assembly described in this embodiment sets a first crossbeam between the two first columns, and the first crossbeam and the second crossbeam are both supported by the first column, so that the bottoms of the first crossbeam and the second crossbeam do not need to be at the same height. On this basis, the height of the second crossbeam is lowered by avoiding the water and electricity pipelines from the first crossbeam at the upper part of the driveway and shortening the net distance between the second column and the adjacent first column, thereby making room for the height of the water and electricity pipelines at the bottom of the second crossbeam. Without damaging the first crossbeam and the second beam, the space requirement for the water and electricity pipelines is met without increasing the height of the basement, thereby saving construction costs.

[0043] Example 1

[0044] like Figure 1-5 As shown, the underground garage fire wall door assembly described in this embodiment includes two first columns 2 arranged at intervals, a first cross beam 3 is connected between the two longitudinal beams 1, a second cross beam 4 is arranged on the side of the first column 2 away from the first cross beam 3, and the bottom of the second cross beam 4 is higher than the bottom height of the first cross beam 3.

[0045] In a preferred embodiment, the height of the first crossbeam 3 is higher than the second crossbeam 4, and the second crossbeam 4 is connected to the second column 17 on the side away from the first column 2. The net distance between the second column 17 and the adjacent first column 2 is L1, and the net distance between adjacent first columns 2 is L2, L1<L2; preferably, L1≤4m, L2≤7.5m.

[0046] More preferably, 3m≤L1≤4m. Still more preferably, 5m≤L2≤7.5m.

[0047] In a preferred embodiment, it further includes a water and electricity pipeline 5 , which passes through the second crossbeam 4 from the lower part of the second crossbeam 4 , and the bottom height of the water and electricity pipeline 5 is equal to or higher than the bottom height of the first crossbeam 3 .

[0048] The underground garage fire wall door assembly described in this embodiment sets the first crossbeam 3 between the two first columns 2, and the first crossbeam 3 and the second crossbeam 4 are both supported by the first column 2, so that the bottoms of the first crossbeam 3 and the second crossbeam 4 do not need to be at the same height. On this basis, the water and electricity pipeline 5 is avoided by the first crossbeam 3 on the upper part of the driveway and the net distance between the second column 17 and the adjacent first column 2 is shortened to reduce the height of the second crossbeam 4, thereby making room for the water and electricity pipeline 5 at the bottom of the second crossbeam 4. Without damaging the first crossbeam 3 and the second beam 4, the space requirement of the water and electricity pipeline 5 is met without increasing the height of the basement, thereby saving construction costs.

[0049] To address the drawback of the relatively high beam position at the fire door of the underground garage, this embodiment reduces the span of the frame beam, i.e., the second beam 4, at an adjacent position to lower the beam height of the second beam 4, thereby freeing up height space for the water and electricity pipelines 5, allowing the water and electricity pipelines 5 to pass through the lower part of the second beam 4 without increasing the height of the basement, thereby solving the above problem without significantly increasing the construction cost of the basement.

[0050] From another perspective: the underground garage fire wall door assembly described in this embodiment is achieved by arranging the first crossbeam 3 between the two columns 2, and the first crossbeam 3 and the second crossbeam 4 are both supported by the first column 2. At the same time, the bottoms of the first crossbeam 3 and the second crossbeam 4 do not need to be at the same height. On this basis, the water and electricity pipeline 5 is avoided by the first crossbeam 3 on the upper part of the driveway, and the net distance between the second column 17 and the adjacent first column 2 is shortened to reduce the height of the second crossbeam 4. The lower part of the second crossbeam 4 can make room for the water and electricity pipeline 5. Without damaging the second crossbeam 4, the height of the underground garage fire wall door assembly is reduced. Furthermore, while complying with the minimum height of the building structure beam and being safe, the overall height of the basement can be reduced, thereby saving construction costs.

[0051] In a preferred manner, along the length direction of the first crossbeam 3 , the first crossbeam 3 and the second crossbeam 4 at least partially overlap.

[0052] In a preferred embodiment, the first crossbeam 3 and the second crossbeam 4 are connected.

[0053] In a preferred embodiment, the first cross beam 3 and the second cross beam 4 are integrally provided.

[0054] In the above preferred embodiment, along the length direction of the first crossbeam 3 , the first crossbeam 3 and the second crossbeam 4 at least partially overlap.

[0055] In a preferred embodiment, a fire wall 6 is provided at the lower portion of the second cross beam 4 , and a hole 8 is provided on the fire wall 6 , through which the water and electricity pipeline 5 passes, and the water and electricity pipeline 5 is sealed and matched with the hole 8 .

[0056] Specifically, the water and electricity pipeline 5 and the hole 8 are sealed by a rubber strip that can withstand high temperatures or a flexible sleeve that can withstand high temperatures.

[0057] In a further preferred embodiment, the water and electricity pipeline 5 includes a water pipe 15 and an electric bridge 16 , and the water pipe 15 is located on one side of the electric bridge 16 to minimize the overall height of the water and electricity pipeline 5 .

[0058] The electric bridge 16 is also commonly called a cable bridge or a wire bridge, and is preferably a frame structure or a square tube structure.

[0059] Example 2

[0060] The underground garage fire wall door assembly described in this embodiment is different from that in Example 1 in that: on the basis of making room for the water and electricity pipeline 5 at the lower part of the second crossbeam 4, the top of the second crossbeam 4 is made higher than the first crossbeam 3, thereby meeting the better load-bearing requirements of the second crossbeam 4 and ensuring the safety of the building structure beams.

[0061] Example 3

[0062] like Figure 1-5 As shown, the underground garage fire wall door assembly described in this embodiment is different from that of embodiment 1 or 2 in that: a longitudinal beam 1 is supported on the first column 2, and the longitudinal beam 1 is perpendicular to the first cross beam 3.

[0063] During construction, the longitudinal beam 1 is preferably arranged parallel to the side lane 18 .

[0064] In a preferred embodiment, the thickness of the longitudinal beam 1 is smaller than the width of the first column 2 .

[0065] In a preferred embodiment, the water and electricity pipeline 5 passes through the longitudinal beam 1 from the lower part of the longitudinal beam 1.

[0066] In a preferred embodiment, the bottom of the longitudinal beam 1 is flush with the bottom of the second transverse beam 4 .

[0067] In a further preferred embodiment, the water and electricity pipeline 5 passes through the longitudinal beam 1 from the lower part of the longitudinal beam 1 so as not to affect the strength of the longitudinal beam 1 .

[0068] In a preferred embodiment, the longitudinal beam 1, the first cross beam 3 and the second cross beam 4 are all supported by the corresponding first column 2. In this case, the diameter of the first column 2 needs to be larger, and the increased cost is much smaller than the cost saved by the overall reduction of the underground garage.

[0069] In a preferred embodiment, two first upright columns 2 disposed at intervals and the first crossbeam 3 together enclose a door opening 7 for vehicles to pass through.

[0070] In a preferred embodiment, the thickness of the longitudinal beam 1 is smaller than the width of the first column 2 .

[0071] Example 4

[0072] like Figure 1-5 As shown, an underground garage system according to this embodiment includes an underground garage fire wall door assembly according to embodiment 1, 2, or 3, wherein the first crossbeam 3 is located above the driveway 18. By arranging the first crossbeam 3 between the two first columns 2, and the first crossbeam 3 and the second crossbeam 4 being supported by the first columns 2, the bottoms of the first crossbeam 3 and the second crossbeam 4 do not need to be at the same height. On this basis, by avoiding the water and electricity pipeline 5 from the first crossbeam 3 at the upper part of the driveway and shortening the net distance between the second column 17 and the adjacent first column 2, the height of the second crossbeam 4 is lowered, thereby freeing up height space for the water and electricity pipeline 5 at the lower part of the second crossbeam 4. Without damaging the first crossbeam 3 and the second crossbeam 4, the space requirement for the water and electricity pipeline 5 is met without increasing the height of the basement, thereby saving construction costs.

[0073] From another perspective, the underground garage system described in this embodiment can reduce the height of the underground garage fire wall door assembly, and thus reduce the overall height of the basement while meeting the minimum height of the building structure beams and being safe, thereby saving construction costs.

[0074] By making room for the water and electricity pipelines 5 at the lower part of the second beam 4 without damaging the second beam 4, the height of the underground garage fire wall door assembly can be lowered. In addition, while meeting the minimum height of the building structure beams and ensuring safety, the overall height of the basement can be lowered, thereby saving construction costs.

[0075] In a preferred embodiment, two first upright columns 2 arranged at intervals and the first crossbeam 3 together enclose a doorway 7 for vehicles to pass through. The doorway 7 is located on a lane 18 .

[0076] In a preferred embodiment, an underground garage system described in this embodiment further includes a fireproof rolling shutter door 9, wherein the fireproof rolling shutter door 9 includes a curtain plate 10 and a reel 11 for retracting and extending the curtain plate 10, and the reel 11 is located in a shutter box 12. By arranging the shutter box 12 on one side of the first beam 3, the height occupied by the fireproof rolling shutter door 9 as a whole can be effectively reduced on the basis of meeting the minimum height of the door opening 7, so that the underground garage fire wall door assembly described in this application can still meet the height requirements for installation and use of the fireproof rolling shutter door 9 while reducing the overall height of the basement.

[0077] In a preferred embodiment, the top support of the underground garage fire wall door assembly is connected with a layer plate structure 13.

[0078] In a preferred embodiment, a covering layer 14 is provided above the layer plate structure 13 .

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
