Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of fireproof plugging materials, in particular to a thermal expansion carbonization formed plugging structure and a plugging system. BACKGROUND

[0002] Fire blocking bag is a common fireproof plugging material, mainly used for fireproof plugging of cable holes, pipe wall holes, equipment gaps and other positions in the fields of building, power and communication, so as to prevent the spread of fire, high temperature and toxic smoke.

[0003] Early fire blocking bags usually adopt a simple structure of "filling particles + outer cloth bag", please refer to Figure 1 for details. However, the early fire blocking bags have the following shortcomings:

[0004] Poor fire resistance integrity: when encountering fire, the outer glass fiber bag of the fire blocking bag is easy to be damaged, and the internal filling particles are scattered, resulting in loss of fire resistance integrity and inability to effectively prevent the spread of fire;

[0005] Poor moisture resistance: the moisture resistance of the traditional fire blocking bag is limited, and in a humid environment such as an underground cable trench, a tunnel and the like, the traditional fire blocking bag has poor moisture resistance, so that the internal filling particles will be deteriorated due to moisture, affecting the expansion performance and heat insulation effect when encountering fire, and even causing the fire blocking bag to lose the fire blocking ability; due to the agglomeration of the filling particles after absorbing water, the weight of the fire blocking bag increases sharply, causing the fireproof thermal expansion carbonization formed plugging structure to collapse and be damaged.

[0006] Large amount of dust: since the expanded light material and the flame retardant are filled in the fire blocking bag in a single individual, and the flame retardant is generally in powder form, the internal filling particles in powder form are easy to overflow from the gap or sewing port of the outer cloth bag during the installation process due to external extrusion, which not only pollutes the installation site environment, but also interferes with the operation of the user.

[0007] In order to solve the technical problems of the traditional fire blocking bag, a new type of fire blocking bag is disclosed in Chinese patent document No. CN 104069600 A. However, in actual application, for some thermal expansion carbonization formed plugging structures with relatively large plugging space, multiple fire blocking bags are usually stacked and attached. However, due to the size of the plugging space being not fixed, when stacking on site, the remaining gap between the last row of fire blocking bags and the hole is often smaller than the thickness of the fire blocking bag, and at this time, multiple small size fire blocking bags need to be replaced, resulting in the need to carry multiple small size fire blocking bags to adapt to different size gaps for plugging, and the multiple small size fire blocking bags have a high probability of being missed.

As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0035] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments,

[0036] As Figure 1 and Figure 2As shown, the thermal expansion carbonization formed plugging structure 10 in an embodiment includes a first elastic fireproof module 100 and a thermal expansion carbonization formed fire blocking module 200, the thermal expansion carbonization formed fire blocking module 200 is used to be embedded in the hole 20 to be plugged, the thermal expansion carbonization formed fire blocking module 200 is correspondingly formed with a threading groove 210, the first elastic fireproof module 100 is embedded in the threading groove 210, the first elastic fireproof module 100 is formed with a wire hole 110, the thermal expansion carbonization formed plugging structure 10 further includes a second elastic fireproof module 400, the second elastic fireproof module 400 is embedded in the remaining gap between the thermal expansion carbonization formed fire blocking module 200 and the hole 20; the second elastic fireproof module 400 is an integrated structure; the thermal expansion carbonization formed fire blocking module 200 is stacked by a plurality of thermal expansion carbonization formed fire blocking bags 220, the thermal expansion carbonization formed fire blocking bag 220 includes a fireproof wrapping bag and a plurality of polyurethane thermal expansion carbonization formed fireproof and flame-retardant particle blocks filled in the fireproof wrapping bag.

[0037] It can be understood that, since the second elastic fireproof module 400 is embedded in the remaining gap between the thermal expansion carbonization formed fire blocking module 200 and the hole 20, and the second elastic fireproof module 400 is an integrated structure, the user can cut the second elastic fireproof module 400 according to the stacking situation on site, effectively avoiding the problem that the traditional fire blocking bag has a high probability of being missed due to the need to carry a variety of small-sized fire blocking bags at the same time; and the integrated second elastic fireproof module 400 is convenient for the user to quickly assemble, reduces the stacking times to improve the assembly efficiency, and since the second elastic fireproof module 400 has good elasticity, it can well adapt to plugging of a variety of different size gaps, thereby improving the adaptability of the thermal expansion carbonization formed plugging structure 10.

[0038] It can also be understood that, since the thermal expansion carbonization formed fire blocking module 200 is stacked by a plurality of thermal expansion carbonization formed fire blocking bags 220, the thermal expansion carbonization formed fire blocking bag 220 includes a fireproof wrapping bag and a plurality of polyurethane thermal expansion carbonization formed fireproof and flame-retardant particle blocks filled in the fireproof wrapping bag, that is, the polyurethane thermal expansion carbonization formed fireproof and flame-retardant particle blocks are used as filling materials, the moisture resistance of the polyurethane thermal expansion carbonization formed fireproof and flame-retardant particle blocks is improved, thereby improving the stability of the thermal expansion carbonization formed plugging structure 10 during long-term storage, so that it is not necessary to additionally increase the number of layers of the fireproof wrapping bag to ensure that the thickness of the fireproof wrapping bag does not become thicker, thereby ensuring that the plurality of polyurethane thermal expansion carbonization formed fireproof and flame-retardant particle blocks filled therein can quickly absorb the heat of the flame to effectively control the problem that the initial fire spreads more seriously, thereby avoiding the problem that the traditional fireproof wrapping bag causes the filling particles to be unable to quickly absorb the heat of the flame due to the increase in the number of layers, resulting in more serious spread of the flame, which is especially suitable for plugging applications in buildings with high humidity.

[0039] In one of the embodiments, the plugging structure further comprises a cable trough box 930, which is arranged between the first elastic fireproof module 100 and the thermal expansion carbonization formed fireproof module 200, i.e. the cable trough box 930 is embedded in the wire trough 210, the first elastic fireproof module 100 is embedded in the cable trough box 930, and the first elastic fireproof module 100 is formed with a plurality of wire holes 110, each wire hole 110 is arranged in one-to-one correspondence with each cable 931, so that the added cable trough box 930 can realize better collection, induction and classification of a plurality of cables 931, so as to facilitate subsequent rapid installation.

[0040] In one of the embodiments, the thermal expansion carbonization formed plugging structure 10 further comprises a first metal composite fireproof plate 600, which is arranged on the first side of the thermal expansion carbonization formed fireproof module 200; the first metal composite fireproof plate 600 is correspondingly formed with the wire trough 210, so that the added first metal composite fireproof plate 600 can further improve the fireproof and flame-retardant performance of the thermal expansion carbonization formed plugging structure 10, and the added first metal composite fireproof plate 600 can be used as a support plate to better adapt to the application of some hole 20 without support structure, such as the plugging application of the hole 20 of the cable shaft, cable tunnel and channel, as shown in Figure 3 and Figure 5 .

[0041] For example, as shown in Figure 3 , in one of the embodiments, the application of the thermal expansion carbonization formed plugging structure 10 in the cable shaft, the hole 20 is formed with a first accommodating cavity and a second accommodating cavity in communication, the first accommodating cavity is used to accommodate the first elastic fireproof module 100, the metal composite fireproof plate is arranged at the bottom of the second accommodating cavity and forms a plugging cavity with the inner wall of the second accommodating cavity, the thermal expansion carbonization formed fireproof module 200 is arranged in the plugging cavity, and the second elastic fireproof module 400 is sealed and filled in the gap between the thermal expansion carbonization formed fireproof module 200 and the inner wall of the plugging cavity, so as to effectively plug the hole 20 of the cable shaft.

[0042] It can be understood that, since the thermal expansion carbonization formed fireproof module 200 is stacked by a plurality of thermal expansion carbonization formed fireproof packages 220, i.e. the user needs to stack the fireproof packages one by one on site, which will cause the problem of low assembly efficiency, especially for some relatively large plugging space, the phenomenon of low assembly efficiency will be more obvious.

[0043] Therefore, as shown in Figure 4 and Figure 5As shown, in one embodiment, the thermal expansion carbonization formed plugging structure 10 further comprises a second metal composite fireproof plate 700 and a fireproof mounting frame 800, which is used for detachable connection with the inner wall of the hole 20, so that the user can disassemble; the second metal composite fireproof plate 700 is arranged on the second side of the fireproof mounting frame 800, and together with the first metal composite fireproof plate 600 and the fireproof mounting frame 800, it forms a mounting cavity 810, and the thermal expansion carbonization formed fireproof module 200 is clamped in the mounting cavity 810, so that the first metal composite fireproof plate 600, the second metal composite fireproof plate 700, the thermal expansion carbonization formed fireproof module 200, the fireproof mounting frame 800 and the first elastic fireproof module 100 can be used as a whole, which is convenient for the user to assemble and fix the first metal composite fireproof plate 600, the second metal composite fireproof plate 700, the thermal expansion carbonization formed fireproof module 200, the fireproof mounting frame 800 and the first elastic fireproof module 100 in advance, so that the user can quickly install on site, thereby improving the efficiency of on-site assembly and effectively avoiding the problem of low assembly efficiency caused by the need to stack fireproof blocks one by one during traditional on-site assembly; the second metal composite fireproof plate 700 corresponds to the wire slot 210, so that the cable 931 can pass through.

[0044] It can be understood that the number of cable passing through the cable tunnel or channel is relatively large, which causes the hole 20 of the cable tunnel or channel to be larger than the conventional hole. If the equipment is not purchased in place and the project is in urgent need of operation, the number of cable passing through in the early stage is relatively small, which causes the actual plugging space to be relatively large. Since the plugging space is relatively large and there is no support in the middle part, if a plurality of thermal expansion carbonization formed fireproof blocks 220 are directly stacked, the middle part of the relatively large plugging space is prone to collapse. Therefore, in one embodiment, the thermal expansion carbonization formed plugging structure 10 further comprises a fireproof support frame 900, which is arranged in the middle part of the mounting cavity 810 and connected with the fireproof mounting frame 800, so that the added fireproof support frame 900 can better support the stress of part of the thermal expansion carbonization formed fireproof blocks 220, effectively avoiding the problem that the middle part of the relatively large plugging space is prone to collapse.

[0045] It can also be understood that the added fireproof support frame 900 can play a certain limiting role and flatness correction role for the stacked thermal expansion carbonization formed fireproof blocks 220, so as to ensure the flatness and plugging effect of the thermal expansion carbonization formed fireproof module 200, and effectively avoid the problem that the thermal expansion carbonization formed fireproof blocks 220 cannot better control the flatness of the final stacking due to the movable gap of the thermal expansion carbonization formed fireproof and flame-retardant particles, resulting in poor plugging effect.

[0046] As shown, Figure 4As shown, in one of the embodiments, the fireproof support frame 900 includes a main frame 910 and a plurality of cross supports 920, the main frame 910 is vertically arranged at the middle of the fireproof mounting frame 800, and a plurality of cross supports 920 are arranged along the length direction of the main frame 910, and the first mounting groove and a plurality of second mounting grooves are respectively formed in the heat expansion carbonization formed fireproof module 200, the first mounting groove is used to accommodate the main frame 910; the second mounting groove is used to accommodate the cross support 920, so as to ensure that the added main frame 910 and a plurality of cross supports 920 can provide support, limiting and flatness correction for the stacked plurality of heat expansion carbonization formed fireproof packs 220, so as to realize effective sealing of the larger plugging space, and also avoid the problem that the middle of the larger plugging space is prone to collapse.

[0047] As shown in the embodiment, the first end of the cross support 920 is connected with the main frame 910, and the second end of the cross support 920 is connected with the fireproof mounting frame 800, so as to enhance the connection strength of the cross support 920, so as to ensure that the plurality of heat expansion carbonization formed fireproof packs 220 stacked on the cross support 920 are not prone to collapse, and so as to ensure that the cross support 920 can provide better flatness correction and support for the stacked plurality of heat expansion carbonization formed fireproof packs 220. Figure 4 In the embodiment, since the cross support 920 is made of metal fireproof composite material, the cross support 920 itself has better flatness, so as to ensure that the cross support 920 can provide better flatness correction for the stacked heat expansion carbonization formed fireproof packs 220, and effectively avoid the phenomenon that the larger plugging space collapses due to too many stacked quantities.

[0048] As shown in the embodiment, the first end of the cross support 920 is connected with the main frame 910, and the second end of the cross support 920 is connected with the fireproof mounting frame 800, so as to enhance the connection strength of the cross support 920, so as to ensure that the plurality of heat expansion carbonization formed fireproof packs 220 stacked on the cross support 920 are not prone to collapse, and so as to ensure that the cross support 920 can provide better flatness correction and support for the stacked plurality of heat expansion carbonization formed fireproof packs 220.

[0049] Figure 5 As shown in the embodiment, the threading groove 210 includes a first threading sub-groove 211, a second threading sub-groove 212 and a third threading sub-groove 213, the heat expansion carbonization formed fireproof module 200 is provided with the first threading sub-groove 211, the second threading sub-groove 212 is formed at the position corresponding to the first threading sub-groove 211 of the first metal composite fireproof plate 600, and the third threading sub-groove 213 is formed at the position corresponding to the first threading sub-groove 211 of the second metal composite fireproof plate 700, and the first elastic fireproof module 100 is sequentially embedded in the first threading sub-groove 211, the second threading sub-groove 212 and the third threading sub-groove 213, so that the first elastic fireproof module 100 can be sealed and filled in the threading groove 210 of the first metal composite fireproof plate 600, the second metal composite fireproof plate 700 and the heat expansion carbonization formed fireproof module 200, thereby effectively ensuring the plugging effect.

[0050] ​In one embodiment, the total amount of expansion of each of the polyurethane thermal expansion carbonization formed fireproof and flame-retardant granular blocks is not less than the unfilled amount of the fireproof wrapping bag, so that each of the polyurethane thermal expansion carbonization formed fireproof and flame-retardant granular blocks expands to form a fireproof and heat-insulating barrier layer without particle scattering when encountering an open flame.

[0051] It can be understood that, since the total amount of expansion of each of the polyurethane thermal expansion carbonization formed fireproof and flame-retardant granular blocks is not less than the unfilled amount of the fireproof wrapping bag, it is ensured that all the polyurethane thermal expansion carbonization formed fireproof and flame-retardant granular blocks filled in the fireproof wrapping bag can completely fill the fireproof wrapping bag after expansion when encountering an open flame. Thus, as the temperature continuously rises, the polyurethane thermal expansion carbonization formed fireproof and flame-retardant granular blocks filled in the fireproof wrapping bag can be in close contact and bonded to form a whole, effectively avoiding the problem of falling of the polyurethane thermal expansion carbonization formed fireproof and flame-retardant granular blocks, so that all the polyurethane thermal expansion carbonization formed fireproof and flame-retardant granular blocks confined in the fireproof wrapping bag will eventually carbonize and expand to form a whole uniform porous fireproof and heat-insulating barrier layer without particle scattering, and the specific heat capacity of the whole uniform porous fireproof and heat-insulating barrier layer is extremely low, which can effectively prevent the spread of flames and smoke in a fire.

[0052] In one embodiment, the filling amount of each of the polyurethane thermal expansion carbonization formed fireproof and flame-retardant granular blocks in the fireproof wrapping bag is 75%-90%, so as to ensure that the filling amount of the polyurethane thermal expansion carbonization formed fireproof and flame-retardant granular blocks filled in the fireproof wrapping bag is appropriate. On the one hand, it ensures that there is a certain activity gap between the polyurethane thermal expansion carbonization formed fireproof and flame-retardant granular blocks filled in the fireproof wrapping bag, so as to better adapt the thermal expansion carbonization formed fireproof and flame-retardant bag 220 to different types and sizes of thermal expansion carbonization formed plugging structures 10 with higher humidity; on the other hand, it ensures that the polyurethane thermal expansion carbonization formed fireproof and flame-retardant granular blocks filled in the fireproof wrapping bag can rapidly absorb heat and expand when encountering an open flame, and form a whole uniform porous fireproof and heat-insulating barrier layer on the fire surface of the polyurethane thermal expansion carbonization formed fireproof and flame-retardant granular blocks, thereby ensuring the fireproof integrity of the thermal expansion carbonization formed fireproof and flame-retardant bag 220, and effectively preventing the spread of flames and smoke.

[0053] It can be understood that, since the general fireproof wrapping bag has a certain porosity, if the particle size of the polyurethane thermal expansion carbonization formed fireproof and flame-retardant particle block is less than 1 mm, it is easy to cause the problem of leakage of the thermal expansion carbonization formed fireproof bag 220, and if the particle size of the polyurethane thermal expansion carbonization formed fireproof and flame-retardant particle block is greater than 10 mm, it is easy to cause the problem that the thermal expansion carbonization formed fireproof bag 220 is damaged due to external force during installation. Therefore, in one embodiment, the particle size of each polyurethane thermal expansion carbonization formed fireproof and flame-retardant particle block is 2 mm-10 mm, so as to avoid the problem of leakage of the thermal expansion carbonization formed fireproof bag 220 due to too small polyurethane thermal expansion carbonization formed fireproof and flame-retardant particle block, and also avoid the problem of high probability of damage of the fireproof wrapping bag during installation due to too large polyurethane thermal expansion carbonization formed fireproof and flame-retardant particle block.

[0054] It is worth mentioning that the formula of the polyurethane thermal expansion carbonization formed fireproof and flame-retardant particle block belongs to the prior art and can be obtained from existing literature, and does not belong to the protection scope of the present disclosure. The present disclosure only protects the connection method of the polyurethane thermal expansion carbonization formed fireproof and flame-retardant particle block and the fireproof wrapping bag.

[0055] In one embodiment, the fireproof wrapping bag is a glass fiber bag with a thickness of 0.1 mm-1.0 mm. In this way, the number of layers of the fireproof wrapping bag does not need to be increased, so as to ensure that the thickness of the fireproof wrapping bag does not increase, thereby ensuring that the plurality of polyurethane thermal expansion carbonization formed fireproof and flame-retardant particle blocks filled therein can quickly absorb the heat of the flame, so as to effectively control the problem of serious spread of the initial fire, thereby avoiding the problem that the spread of the flame is more serious due to the fact that the filling particles cannot quickly absorb the heat of the flame in the traditional fireproof wrapping bag with increased number of layers.

[0056] In one embodiment, the thermal expansion carbonization formed plugging structure 10 further comprises a locking member, the fireproof mounting frame 800 is correspondingly provided with a mounting hole, and the inner wall of the hole 20 is correspondingly formed with a threaded hole. The locking member sequentially passes through the mounting hole and the threaded hole and is screwed with the inner wall of the threaded hole, so as to realize the detachable setting of the fireproof mounting frame 800 and the hole 20.

[0057] The present disclosure also provides a plugging system comprising the thermal expansion carbonization formed plugging structure 10 according to any one of the above embodiments.

[0058] Compared with the prior art, the present disclosure has at least the following advantages:

[0059] 1) Since the second elastic fireproof module 400 is embedded in the remaining gap between the thermal expansion carbonization forming fireproof module 200 and the hole 20, and the second elastic fireproof module 400 is an integral structure, the user can cut the second elastic fireproof module 400 according to the on-site stacking situation, effectively avoiding the problem that the traditional fireproof package has a high probability of being missed due to the need to carry a variety of small-sized fireproof packages at the same time; and the integrally formed second elastic fireproof module 400 is convenient for the user to quickly assemble, reduces the stacking times to improve the assembly efficiency, and since the second elastic fireproof module 400 has good elasticity, it can well adapt to the plugging of various different size gaps, thereby improving the adaptability of the thermal expansion carbonization forming plugging structure 10.

[0060] 2) Since the thermal expansion carbonization forming fireproof module 200 is stacked by a plurality of thermal expansion carbonization forming fireproof packages 220, the thermal expansion carbonization forming fireproof package 220 includes a fireproof wrapping bag and a plurality of polyurethane thermal expansion carbonization forming fireproof and flame-retardant particle blocks filled in the fireproof wrapping bag, that is, the polyurethane thermal expansion carbonization forming fireproof and flame-retardant particle blocks are used as fillers, which improves the moisture resistance of the polyurethane thermal expansion carbonization forming fireproof and flame-retardant particle blocks, thereby improving the long-term storage stability of the thermal expansion carbonization forming plugging structure 10, so that the number of layers of the fireproof wrapping bag does not need to be increased, to ensure that the thickness of the fireproof wrapping bag does not thicken, thereby ensuring that the plurality of polyurethane thermal expansion carbonization forming fireproof and flame-retardant particle blocks filled therein can quickly absorb the heat of the flame, to effectively control the problem of more serious initial fire spread, to avoid the problem that the traditional fireproof wrapping bag causes the filling particles to be unable to quickly absorb the heat of the flame due to the increase in the number of layers, resulting in more serious flame spread, especially suitable for plugging applications in buildings with higher humidity.

[0061] The above-described embodiments only express several embodiments of the present disclosure, which are described in a more specific and detailed manner, but should not be understood as limiting the scope of the disclosed patent. It should be noted that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present disclosure, which are within the scope of protection of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the appended claims.
