Description

Technical Field

[0001] The invention relates to the technical field of fire-fighting and life-saving devices, and in particular to a life-saving passage for a high-rise building and a manufacturing method thereof. Background Art

[0002] With the development of society, there are more and more high-rise buildings in cities and rural areas. When a fire occurs in a high-rise building, how to escape in time has always been a difficult problem. At present, when a fire occurs in a high-rise building, people escape in two ways: one is to evacuate quickly through the fire passage, that is, the stairs (it is common sense that elevators cannot be taken during a fire). This method is easily blocked by the stairs due to the fire, which may interrupt the escape passage; the other is to wait for fire rescue, evacuate through the fire ladder or jump on the inflatable cushion downstairs to evacuate, but waiting for fire rescue takes time. In the process of fire, time is life. In addition, in some places, it is difficult for fire trucks to enter, and the height of the fire ladder of some high-rise buildings cannot be reached. It also takes time to inflate the fire inflatable cushion, and people jumping on the inflatable cushion are also prone to injury. These are all limitations of fire rescue. In order to solve the problem of people escaping when a fire occurs in a high-rise building, the research on using soft slides for high-rise building fire escape has increased in recent years. For example, a fire-fighting life-saving soft slide disclosed in the Chinese patent document with publication number CN2195955Y, and an emergency escape passage disclosed in the Chinese patent document with authorization announcement number CN205145430U, etc., among which the former has only one entrance and cannot be used for people on different floors to escape at the same time, and there is no deceleration structure in the passage, and the descent speed of the escaped people cannot be controlled, which is easy to cause injuries. The latter has the problem that it is difficult for people to enter the main slide from the secondary slide due to structural limitations, and the main slide is provided with a pedal barrier to slow down the descent of the escaped people in the main slide, which has limited effect and thus poses a safety hazard. The above two patent documents only involve the structure of the soft slide-type life-saving passage, and do not involve its specific manufacturing method.

[0003] The Chinese patent document with application publication number CN116657305A discloses a cylindrical cloth and a weaving method for making a deceleration channel from top to bottom. Its specification claims that it can be used as a life-saving channel in the wild, and also involves its weaving method. However, from its deceleration structure, it is obviously not suitable for high-rise building fire escape. The Chinese patent document with application publication number CN116641167A discloses a wave-type elastic cylindrical cloth and a weaving method. Its specification claims that it can be used for high-altitude escape, but it has only one inlet and outlet and one channel. When used for high-rise building fire escape, it is obviously only suitable for escaping from one point (the roof or a certain floor) and cannot be used for escaping from all floors of the same unit at the same time. In addition, both cylindrical cloths are woven with shuttle looms, have many defects, many yarn joints, and are not strong enough.

[0004] Therefore, it is necessary to develop a high-rise building fire escape device and a manufacturing method thereof of a safer and more effective soft slide class. Summary of the invention

[0005] The purpose of the present invention is to provide a high-rise building lifesaving passage and a manufacturing method thereof in view of the problems existing in the prior art.

[0006] The technical scheme of the present invention is: the high-rise building life-saving passage of the present invention comprises a body, a fire-retardant layer fixedly coated on the inner and outer end surfaces of the body, and a matching connector for fixing the body to the roof or floor when in use, and its structural characteristics are: the above-mentioned body is a foldable integrated part woven once by a double-layer double-rapier jacquard velvet loom, a main passage penetrating up and down is provided in the middle of the body, a main passage entrance and a main passage exit are respectively provided on the upper and lower sides of the main passage, side seams are provided on the left and right sides of the main passage, narrow interval sections and wide interval sections are alternately provided from top to bottom between the main passage entrance and the main passage exit of the main passage, and the number of groups of the narrow interval sections and the wide interval sections is the same as the number of floors of the high-rise building to which it is applied; a floor passage obliquely arranged from top to bottom and communicating with the main passage is provided on the body for each floor, the floor passage is provided with a floor passage entrance and a floor passage exit, and the floor passage exit of each floor passage is communicated with a corresponding wide interval section, and when in use, the floor passage entrance of each floor passage corresponds to the window or balcony position of a corresponding floor of the high-rise building.

[0007] A further solution is that the narrow interval section is a hollow section which is wide at the upper and lower sides and narrow in the middle, and the wide interval section is a hollow section which is narrow at the upper and lower sides and wide in the middle.

[0008] A further solution is that the width of the narrow middle part of the narrow interval segment is smaller than the shoulder width of a normal adult; the width of the narrow upper and lower parts of the wide interval segment is larger than the shoulder width of a normal adult.

[0009] A further solution is that the material used to weave the above-mentioned body is a warp yarn made of a strong industrial chemical fiber material and a weft yarn made of a strong industrial chemical fiber stretch yarn material.

[0010] A further solution is: the above-mentioned strong industrial chemical fiber yarn is 1000d high-strength and low-stretch polyester-polyester chemical fiber yarn; the strong industrial chemical fiber stretch yarn is a mixture of 800d high-strength yarn and 300d spandex yarn.

[0011] A method for manufacturing the above-mentioned high-rise building rescue passage comprises the following steps: The first step is to design the pattern on the pattern paper, including the following steps: ① Draw the structure of the high-rise building rescue passage as mentioned above on the design paper; ② Determine the width of the narrow interval section of the main passage on both sides and the width of the narrowest part in the middle, the width of the wide interval section at the widest part in the middle, and the length of the narrow interval section and the wide interval section in the vertical direction respectively, and make the sum of the lengths of the narrow interval section and the wide interval section equal to the height of one floor of the high-rise building; ③ Determine the diameter, inclination angle, and location of the floor passage entrance and exit, and make the distance between two adjacent floor passage entrances equal to the height of one floor; ④ Considering the shrinkage rate of the main body during weaving and finishing, the parameters are magnified accordingly, and finally the final parameters of the main body weaving process are determined; ⑤ Paint all channels on the pattern paper white and all side seams black; and clearly express how the first to fourth warp yarns used to weave the side seams of the main body are transformed into the first warp yarn of the upper layer, the first warp yarn of the lower layer, the second warp yarn of the upper layer, and the second warp yarn of the lower layer in the channels where black and white are alternating, i.e., wide becomes narrow and narrow becomes wide; The second step is to weave the main body according to the design on the pattern paper, which specifically includes the following steps: ① Arrange the warp yarn: hang the total warp of the entire width including the main channel of the main body, the floor channel and the side seam on the jacquard creel of the double-layer double-rapier jacquard velvet loom; ② Drawing in the reed: All the warp yarns are inserted into the velvet warp heddle of the jacquard in the order of four yarns from left to right, from the first to the fourth yarn; ③Lifting the harness, throwing the shuttle and beating the weft: The main channel of the main body, the floor channel and the entire width of the side seam are all woven with 4 warp yarns as a warp unit, and 2 upper and 2 lower layers, a total of 4 weft yarns as a weft unit, and the specific method is: First shuttle: lift up the first warp yarn of the upper layer in the jacquard velvet warp heald in the channel, and sink the first warp yarn of the lower layer in the jacquard velvet warp heald in the channel; put the second warp yarn of the upper layer in the jacquard velvet warp heald in the channel in the middle, and put the second warp yarn of the lower layer in the jacquard velvet warp heald in the channel in the middle; lift up the first warp yarn and the second warp yarn of the jacquard velvet warp heald in the side seam, and sink the third warp yarn and the fourth warp yarn of the jacquard velvet warp heald in the side seam; then, uniformly put in the first weft yarn of the upper layer and the first weft yarn of the lower layer, and beat the weft for weaving; Second shuttle: lift up the second warp yarn of the upper layer in the jacquard velvet warp heald in the channel, sink the second warp yarn of the lower layer in the jacquard velvet warp heald in the channel, put the first warp yarn of the upper layer in the jacquard velvet warp heald in the channel in the middle, put the first warp yarn of the lower layer in the jacquard velvet warp heald in the channel in the middle; lift up the third warp yarn and the fourth warp yarn in the jacquard velvet warp heald in the side seam, sink the first warp yarn and the second warp yarn in the jacquard velvet warp heald in the side seam, and then uniformly put in the second weft yarn of the upper layer and the second weft yarn of the lower layer to beat the weft for weaving; Repeat step ③ according to the design on the sample paper to weave in a loop until the entire weaving of the body is completed; The third step is the post-finishing of the body: the fire retardant layer is fixed on the inner and outer end surfaces of the body; The fourth step is to provide connecting parts for fixing during use.

[0012] A further solution is: in step ④ of the first step of the above manufacturing method, the parameters are correspondingly enlarged with the shrinkage rate of the body being 70%, and finally the final parameters in the body weaving process are determined.

[0013] The present invention has positive effects: (1) The high-rise building rescue passage of the present invention, through the improvement of the overall structure, especially the structure of the sliding passage and the floor passage, enables the fire escapers of the high-rise building to use the present invention to safely and effectively slide down to the ground for escape no matter which floor they are on, effectively preventing the risk of the escapers sliding down to the ground and getting injured, solving the corresponding technical problems existing in similar devices in the prior art, and the structure is simple, the price is relatively low, easy to promote, and easy to store and use.

DETAILED DESCRIPTION

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] (Example 1) See Figures 1 to 3 The high-rise building rescue passage of this embodiment mainly consists of a body 1, a fire-retardant layer (not marked in the figure) fixedly coated on the inner and outer end surfaces of the body 1, and a matching connector (not shown in the figure) used to fix the body 1 to the roof or floor when in use. Among them, the fire-retardant layer and the connector provided on the inner and outer end surfaces of the body 1 are mature existing technologies and are not described in detail.

[0018] The body 1 is a foldable integrated part made of warp yarns made of strong industrial chemical fiber and weft yarns made of strong industrial chemical fiber elastic yarn through one-time continuous weaving on a double-layer double rapier loom. Among them, the strong industrial chemical fiber is 1000d high-strength and low-stretch polyester nylon chemical fiber (1000d is a professional term in the textile field, indicating that 9000 meters of yarn is 1000 grams); the strong industrial chemical fiber elastic yarn is a mixture of 800d high-strength yarn and 300d spandex yarn.

[0019] A main passage 11 is provided in the middle of the main body 1, which is connected vertically. A main passage entrance 11-1 and a main passage exit 11-2 are provided at the upper and lower sides of the main passage 11, respectively. Narrow interval sections 11-3 and wide interval sections 11-4 are provided alternately from top to bottom between the main passage entrance 11-1 and the main passage exit 11-2 of the main passage 11. The number of groups of the narrow interval sections 11-3 and the wide interval sections 11-4 is the same as the number of floors of the high-rise building to which it is applied, that is, each floor of the high-rise building corresponds to a combination of a narrow interval section 11-3 and a wide interval section 11-4 of the main passage 11 of the main body 1. Side seams 11-5 are provided on the left and right sides of the main body 1. The main body 1 has a floor passage 12 arranged obliquely from top to bottom and communicating with the main passage 11 for each floor. The floor passage 12 has a floor passage entrance 12-1 and a floor passage exit 12-2. The floor passage exit 12-2 of each floor passage 12 communicates with a corresponding wide interval section 11-4. When in use, the floor passage entrance 12-1 of each floor passage 12 corresponds to the window 102 or balcony position of the corresponding floor of the high-rise building. The narrow interval section 11-3 is a hollow section with wide upper and lower sides and narrow middle. The width of the narrow middle part of the narrow interval section 11-3 is less than the shoulder width of a normal adult; the wide interval section 11-4 is a hollow section with narrow upper and lower sides and wide middle. The width of the narrow upper and lower sides of the wide interval section 11-4 is greater than the shoulder width of a normal adult.

[0020] The use method and principle of the high-rise building rescue passage of this embodiment are briefly described as follows: The high-rise building rescue passage of this embodiment is very convenient to fold due to the overall structure of the main body 1. It is usually stored in a folded state on the roof of a high-rise building or in the home of a high-rise resident. When a fire occurs, it is only necessary to fix the upper end of the main body 1 with the provided connecting piece on the side of the roof or high-rise home where there is no fire and there is a window 102 or a balcony, and then throw the main body 1 down along the wall 101 with the side of the main body 1 provided with the floor passage 12 facing the floor window 102 or the balcony, so that the roof personnel can enter the main body 1 from the main passage entrance 11-1 of the main body 1. 1, the residents of each floor can escape from the main passage 11 through the floor passage entrance 12-1 and the floor passage exit 12-2 of the corresponding floor passage 12, and each escapee slides to the ground under the action of gravity by relying on his own weight in the main passage 11. During the sliding process, due to the existence of a narrow interval section 11-3 on each floor, the sliding speed of the escapee is blocked and the descending speed is slowed down, so that the escapee can slide safely to the ground and escape to the ground from the main passage exit 11-2 of the main passage to achieve safe escape.

[0021] The manufacturing method of the high-rise building lifesaving passage of this embodiment includes the steps of weaving the body 1, post-treatment of the body 1 with fire retardant, and provision of connectors, wherein the weaving of the body 1 is the core of the manufacturing method of the present invention, and the weaving of the body 1 uses 1000d high-strength and low-stretch polyester nylon chemical fiber as the warp yarn, and 800d high-strength silk plus 300d spandex silk strong industrial chemical fiber elastic yarn as the weft yarn, and on a double-layer double-rapier jacquard velvet loom, the warp and weft yarns are interwoven by using the upper rapier, the lower rapier, and the jacquard velvet warp heald. The manufacturing method specifically includes the following steps: The first step is to design the pattern on the pattern paper. The specific steps include: ① Draw the structure of the high-rise building rescue passage of the above-mentioned present embodiment on the sample paper.

[0022] ② Determine the width of the upper and lower sides of the narrow interval section 11-3 of the main passage 1 and the width of the narrowest part in the middle, the width of the wide interval section 11-4 at the widest part in the middle, and the length of the narrow interval section 11-3 and the wide interval section 11-4 in the upper and lower directions respectively, and make the sum of the lengths of the narrow interval section 11-3 and the wide interval section 11-4 equal to the height of one floor of the high-rise building.

[0023] ③ Determine the diameter and inclination angle of the floor passage 12 and the positions of the floor passage entrance 12-1 and the floor passage exit 12-2. The distance between two adjacent floor passage entrances 12-1 is equivalent to the height of one floor.

[0024] ④ Considering that the shrinkage rate of the main body 1 during weaving and finishing is generally 70% according to industry experience, the above-mentioned related parameters are correspondingly amplified to determine the final weaving parameters of the main body 1 during the weaving process.

[0025] ⑤ For the convenience of viewing the drawings and subsequent description during the weaving process, all channels on the sample paper are painted white and all side seams are painted black. And it is clearly expressed how the first to fourth warp yarns used for the side seams of the weaving body are transformed into the first warp yarn of the upper layer, the first warp yarn of the lower layer, the second warp yarn of the upper layer, and the second warp yarn of the lower layer in the channels where black and white are alternating, i.e., wide becomes narrow and narrow becomes wide; The second step is to weave the body 1 according to the design on the pattern paper, which specifically includes the following steps: ① Arrange the warp yarn: hang the total warp of the entire width including the main channel 11 of the main body 1, the floor channel 12 and the side seam 11-5 on the jacquard creel of the double-layer double-rapier jacquard velvet loom.

[0026] ② Drawing in the reed: Insert all the warp yarns into the jacquard velvet warp heddle in the order of the first to the fourth warp yarns from left to right, with four yarns as a unit.

[0027] ③Lifting the harness, throwing the shuttle and beating the weft: On the sample paper, the main channel 11 of the main body 1, the floor channel 12 and the entire width of the side seam are all woven with 4 warp yarns as a warp unit, and 4 weft yarns, 2 yarns in the upper layer and 2 yarns in the lower layer, as a weft unit, for shuttle weaving.

[0028] See also Figure 3 In order to describe the weaving process more clearly, this step is first artificially divided into the following two steps: Ⅰ and Ⅱ: Ⅰ. For all the white channels on the sample paper, use the following method to beat the weft: First shuttle: lift up the first warp yarn a in the jacquard velvet warp heald in the channel, sink the first warp yarn b in the jacquard velvet warp heald in the channel; put the second warp yarn c in the jacquard velvet warp heald in the channel in the middle, and put the second warp yarn d in the jacquard velvet warp heald in the channel in the middle; put in the first weft yarn W1 in the upper layer and the first weft yarn W3 in the lower layer, and beat the weft for weaving; Second shuttle: lift up the upper second warp yarn c in the jacquard velvet warp heald in the channel, sink the lower second warp yarn d in the jacquard velvet warp heald in the channel, put the upper first warp yarn a in the middle, put the lower first warp yarn b in the jacquard velvet warp heald in the channel; put in the upper second weft yarn W2 and the lower second weft yarn W4, and beat the weft for weaving; Thereby a double-layer cloth with an upper layer and a lower layer is woven, but without side seams 11-5.

[0029] Ⅱ. For all the black parts on the sample paper, i.e. the edge seams, beat the weft as follows: First shuttle: lift up the first warp yarn T1 and the second warp yarn T2 in the velvet warp heald of the large jacquard pattern at the side seam, and sink the third warp yarn T3 and the fourth warp yarn T4 in the velvet warp heald of the large jacquard pattern at the side seam; put in the first double weft yarn W5 which is transitioned from the upper first weft yarn W1 and the lower first weft yarn W3 for beating weaving; Second shuttle: lift up the third warp yarn T3 and the fourth warp yarn T4 in the velvet warp heald of the large jacquard at the edge seam, sink the first warp yarn T1 and the second warp yarn T2 in the velvet warp heald of the large jacquard at the edge seam, put in the second double weft yarn W6 which is transitioned from the upper second weft yarn W2 and the lower second weft yarn W4, and beat the weft for weaving.

[0030] Thereby, the upper layer of cloth and the lower layer of cloth are connected through the side seam 11-5 to form a cylindrical cloth with the side seam 11-5.

[0031] In fact, the method of weaving by lifting the harness, throwing the shuttle and beating the weft in this step is to combine the above-mentioned steps Ⅰ and Ⅱ together, and the specific steps are as follows: First shuttle: lift up the first warp yarn a in the jacquard velvet warp heald in the channel, and sink the first warp yarn b in the jacquard velvet warp heald in the channel; put the second warp yarn c in the jacquard velvet warp heald in the channel in the middle, and put the second warp yarn d in the jacquard velvet warp heald in the channel in the middle; lift up the first warp yarn T1 and the second warp yarn T2 in the jacquard velvet warp heald at the side seam, and sink the third warp yarn T3 and the fourth warp yarn T4 in the jacquard velvet warp heald at the side seam; then, uniformly put in the first weft yarn W1 in the upper layer and the first weft yarn W3 in the lower layer to beat the weft for weaving.

[0032] Second shuttle: lift up the second warp yarn c in the jacquard velvet warp heald in the channel, sink the second warp yarn d in the jacquard velvet warp heald in the channel, put the first warp yarn a in the jacquard velvet warp heald in the channel in the middle, and put the first warp yarn b in the jacquard velvet warp heald in the channel in the middle; lift up the third warp yarn T3 and the fourth warp yarn T4 in the jacquard velvet warp heald at the side seam, sink the first warp yarn T1 and the second warp yarn T2 in the jacquard velvet warp heald at the side seam, and then put in the second weft yarn W2 in the upper layer and the second weft yarn W4 in the lower layer to beat the weft; Repeat step ③ according to the design on the sample paper to weave in a loop until the entire weaving of the main body 1 is completed. After weaving is completed, open the main body 1 to obtain the following: Figure 1 , 2 Body 1 shown.

[0033] The third step is the post-processing of the body 1: the fire-retardant layer is fixedly coated on the inner and outer end surfaces of the body 1. This is a prior art and will not be described in detail.

[0034] The fourth step is to equip the connecting piece for fixing during use. The connecting piece can be a fireproof rope, hook or other tools used for fixing in the prior art, which is the same as the prior art and will not be described in detail.

[0035] At this point, the manufacture of the high-rise building rescue passage of this embodiment is completed.

[0036] The above embodiments are descriptions of specific implementation methods of the present invention rather than limitations of the present invention. Technical personnel in the relevant technical field can make various changes and modifications to obtain corresponding equivalent technical solutions without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should be included in the patent protection scope of the present invention.
