Description

Technical Field

[0001] The present invention belongs to the technical field of component fire resistance performance testing and detection, in particular to a component fire resistance testing device and a component fire resistance testing method. Background Art

[0002] Due to the scarcity of land resources, cities with higher population densities generally construct high-rise buildings to improve land utilization. However, due to the dense population and concentrated property, once a fire occurs, it is very easy to cause the building to burn down or even collapse, resulting in significant casualties and economic losses. Therefore, research on the fire resistance of building components is particularly important.

[0003] In the prior art, fire resistance tests for building components are typically conducted using fire resistance test furnaces. Conventional fire resistance test furnaces are typically constructed using masonry, so their position is fixed and cannot be adjusted to suit the test component. Because each building component is exposed to different fire conditions—for example, beams are exposed to fire on three sides, including the bottom, while columns are exposed to fire on all vertical surfaces—a single fire resistance test furnace can typically only be used to test the fire resistance of one component. This includes testing columns using a column fire resistance test furnace, beam fire resistance test furnaces, and beam-column joints using a beam fire resistance test furnace. This results in limited versatility and high testing costs. Summary of the Invention

[0004] The purpose of the present invention is to provide a component fire resistance test device and a component fire resistance test method to solve the problem that the existing fire resistance test furnace can generally only perform fire resistance tests on one component, has poor versatility and high test costs.

[0016] In one embodiment, the mounting groove is formed by being recessed downward from the top of the furnace body along the depth direction of the accommodating cavity.

[0017] In one embodiment, the component fire resistance testing device further includes a moving device, which is disposed on the supporting assembly and is used to drive the furnace cover to move in a three-dimensional space.

[0038] It should be noted that, in this embodiment, the component fire resistance testing device 100 is mainly used to test the fire resistance of building components, for example, it can be used to test the fire resistance of various building components such as beams, columns, and beam-column joints; it should be further noted that, in other embodiments, the applicable test objects of the component fire resistance testing device 100 include but are not limited to the above-mentioned components 200, and other components 200 that need to undergo fire resistance testing can be applied.

[0039] The present invention provides a component fire resistance test device 100, such as Figure 1As shown, the component fire resistance testing device 100 includes a testing furnace 1 and a supporting assembly 2 .

[0040] like Figure 2 As shown, the test furnace 1 has a receiving cavity 111, and mounting grooves 112 communicating with the receiving cavity 111 are provided on the side walls on opposite sides of the test furnace 1. It is understandable that in this embodiment, the test furnace 1 can be a square body, and mounting grooves 112 are provided on the two side walls on opposite sides of the test furnace 1, that is, two mounting grooves 112 are provided on the side walls of the test furnace 1. The two mounting grooves 112 cooperate to allow the component 200 to pass through so that the component 200 spans the receiving cavity 111, and a combustion state is formed in the receiving cavity 111 to burn the component 200 to test its fire resistance. Of course, in other embodiments, the test furnace 1 can be of other suitable shapes, which are not particularly limited here.

[0041] like Figure 1 and Figure 2 As shown, the support assembly 2 includes a support structure 21 and two loading members 22; specifically in this embodiment, the support structure 21 encloses a receiving space, and the test furnace 1 is received in the receiving space; each loading member 22 is movably connected to the support structure 21, so that the loading member 22 can move up and down relative to the support structure 21 along the depth direction of the receiving cavity 111, and the loading member 22 is located outside the receiving cavity 111 of the test furnace 1 and is correspondingly arranged with the mounting groove 112. The two loading members 22 cooperate to fix the two ends of the component 200 so that the component 20 0 spans the accommodating cavity 111 and drives the component 200 to move up and down in the installation groove 112; it should be noted that there are two installation grooves 112 and two loading members 22, so the installation grooves 112 and the loading members 22 are arranged in a one-to-one correspondence, that is, the two loading members 22 are correspondingly arranged on the support structure 21 according to the positions of the two installation grooves 112 and are movably connected to the support structure 21, and the shape of the installation groove 112 adapts to the needs of the position movement of the component 200, so that the component 200 can move up and down in the installation groove 112 along the depth direction of the accommodating cavity 111. It can be understood that through the movably connected loading member 22 and the support structure 21, when the loading member 22 moves up and down relative to the support structure 21 along the depth direction of the accommodating cavity 111, it can drive the component 200 to move up and down along the depth direction of the accommodating cavity 111, so as to move the component 200 to a preset height for fire resistance testing according to the test requirements of different components 200.

[0042] It can be understood that the working principle of the component fire resistance test device 100 is roughly as follows: when it is necessary to conduct a fire resistance test on the column, one end of the column is fixed to a loading member 22, and the other end passes through the two mounting slots 112 of the test furnace 1 and is fixed to another loading member 22, so that the column body part located between the two ends is accommodated in the accommodating cavity 111, and the position of the loading member 22 relative to the supporting structure 21 is adjusted to make the column rise and fall to the center position of the accommodating cavity 111, and a combustion state is formed in the accommodating cavity 111 to evenly burn the four sides of the column, so that the four sides of the column are evenly affected by the fire. At this time, The columns are subjected to conventional compression and bending performance tests; when the beam needs to be subjected to a fire resistance test, one end of the beam is fixed to a loader 22, and the other end is respectively passed through the two mounting slots 112 of the test furnace 1 and fixed to another loader 22, so that the beam body part located between the two ends is accommodated in the accommodating cavity 111, and the position of the loader 22 relative to the supporting structure 21 is adjusted to adjust the height of the beam, so that the beam rises to the top of the test furnace 1, and a combustion state is formed in the accommodating cavity 111 to evenly burn the left, right and lower surfaces of the beam, while the upper surface of the beam is not affected by fire. At this time, the beam can be subjected to conventional compression and bending performance tests.

[0043] In summary, compared with the prior art, the component fire resistance test device 100 has at least the following beneficial effects: the component fire resistance test device 100 can perform fire resistance tests on different types of components 200 through the cooperation of the test furnace 1 and the support assembly 2; wherein, by movably connecting each loader 22 with the support structure 21, so that the loader 22 can be lifted and lowered relative to the support structure 21 along the depth direction of the accommodating cavity 111, the loader 22 is located outside the accommodating cavity 111 of the test furnace 1, and is arranged corresponding to the mounting groove 112, and the two loaders 22 cooperate to fix the two ends of the component 200, so that when the loader 22 is lifted and lowered relative to the support structure 21 along the depth direction of the accommodating cavity 111, it can drive the component 200 to be lifted and lowered along the depth direction of the accommodating cavity 111, so as to move the component 200 to a preset height for fire resistance testing according to the test requirements of different components 200, thereby improving the versatility of the component fire resistance test device 100 and reducing the test cost.

[0044] In some embodiments, as Figure 1As shown, the support structure 21 includes a connecting frame 211 and two supporting frames 212; along the intersecting direction of the extension direction from one mounting groove 112 to the other mounting groove 112, the two supporting frames 212 are arranged side by side and vertically; specifically, in this embodiment, the two supporting frames 212 are arranged side by side along the perpendicular direction from the extension direction from one mounting groove 112 to the other mounting groove 112, and the two supporting frames 212 each include at least two vertical columns and at least one horizontal beam connecting the vertical columns. Of course, in other embodiments, the supporting frames 212 can be other structures, which are not particularly limited here. Along the depth direction of the accommodating cavity 111, at least two first connecting positions 2121 are provided on the side of the supporting frame 212 close to the mounting groove 112, and second connecting positions (not shown) are provided at both ends of the connecting frame 211. The two ends of the connecting frame 211 are detachably fixed to the two supporting frames 212 through the second connecting positions and the first connecting positions 2121. The loading member 22 is provided on the connecting frame 211. It is understandable that by providing at least two first connection positions 2121 arranged along the depth direction of the accommodating cavity 111 on one side of the support frame 212 close to the mounting groove 112, the number of the first connection positions 2121 can be set according to actual conditions, for example, it can be three, four, five, etc., and is not limited here. The two ends of the connecting frame 211 are connected to the first connection positions 2121 at different positions of the support frame 212 through the second connection positions, so that the connecting frame 211 can be moved up and down in the depth direction of the accommodating cavity 111, thereby driving the loading member 22 connected to the connecting frame 211 to move up and down in the depth direction of the accommodating cavity 111, so as to drive the component 200 connected to the loading member 22 to move to a preset height for fire resistance testing, thereby improving versatility.

[0045] In some embodiments, as Figure 1 As shown, the support frame 212 has at least two first connection holes on one side near the mounting slot 112, the first connection hole being a first connection position 2121. A second connection hole is respectively formed at each end of the connection frame 211, the second connection holes being a second connection position. The ends of the connection frame 211 are fixedly mounted on the support frame 212 by fasteners passing through the second connection holes and the first connection holes in sequence, so that the connection frame 211 is firmly mounted on the support frame 212 by the fasteners and is easy to disassemble. Specifically, the fasteners can be screws, which fasten the connection frame 211 and the support frame 212 together, thereby achieving a stable connection, easy disassembly, and a simple structure. Of course, in other embodiments, the fasteners can be suitable fasteners such as pins, and this is not particularly limited here.

[0046] In some embodiments, as Figure 1As shown, the connecting frame 211 includes three frames 2111, which are connected end to end to form a triangular frame structure. It can be understood that by forming the connecting frame 211 into a triangular frame structure, the loading element 22 can be stably supported and the support assembly 2 can be balanced when the structural member 200 is subjected to performance testing. For example, in this embodiment, when a column is exposed to fire and undergoing a load-bearing performance test, when pressure is applied to the column shaft, this pressure simultaneously affects the support assembly 2. The force is first transmitted to the loading elements 22 at each end of the column, which are then transmitted to the connecting frame 211 and the support frame 212, thereby achieving self-balancing of the loading force. The connecting frame 211 of the triangular frame can further disperse the pressure to further improve the pressure-bearing capacity. In addition, specifically in this embodiment, the connecting frame 211 is connected to the transverse beam of the support frame 212. Therefore, the loading element 22, the connecting frame 211, and the transverse beam of the support frame 212 cooperate to form a self-enclosed loading system, capable of applying pressure exceeding 200 tons to the column.

[0047] In some embodiments, as Figure 1 As shown, the loading member 22 is a long strip beam, which is arranged parallel to the depth direction of the accommodating cavity 111. The loading member 22 may be provided with a groove to facilitate the fixing of the component 200. Of course, in other embodiments, the component 200 can directly abut the side wall of the loading member 22 to form a suspended state. There are two connecting frames 211, which are respectively connected to the top and bottom ends of the loading member 22, so that the loading member 22 can be stably fixed to the support frame 212 through the connecting frames 211.

[0048] In some embodiments, as Figure 1As shown, the component fire resistance testing device 100 further includes a first adjusting device 3, which is disposed at the bottom of the test furnace 1, with the top of the first adjusting device 3 abutting against the bottom of the test furnace 1. The first adjusting device 3 can adjust the height of the test furnace 1 by adjusting the height of its top. It can be understood that the entire height of the test furnace 1 is adjusted by the first adjusting device 3. Since the component 200 is fixed by the loading member 22, the test furnace 1 can be directly adjusted up and down relative to the component 200 by the first adjusting device 3, that is, the height of the test furnace 1 can be raised or lowered to adjust the position of the component 200 in the accommodating cavity 111 to meet various testing requirements for the component 200. For example, when conducting a beam test, the beam is exposed to fire on three sides. The height of the test furnace 1 is adjusted so that the upper surface of the beam is in close contact with the top of the test furnace 1, so that the upper surface of the beam is not exposed to fire, while the left, right and lower sides are exposed to fire. When conducting a column test, the height of the test furnace 1 is adjusted so that the column is adjusted to the center position of the accommodating cavity 111, so that the four sides of the column are evenly exposed to fire. Alternatively, the height of the test furnace 1 is adjusted so that the upper side of the column is in close contact with the top of the test furnace 1, so that the upper surface of the column is not exposed to fire, while the left, right and lower sides are exposed to fire. Column tests under two working conditions can be performed.

[0049] In some embodiments, as Figure 1 As shown, the first adjustment device 3 includes at least three jacks, which are dispersedly arranged at the bottom of the test furnace 1. Specifically, in this embodiment, the at least three jacks are symmetrically arranged about the central axis of the test furnace 1, and the height of the test furnace 1 is adjusted by the jacks. Of course, in other embodiments, the first adjustment device 3 can be other suitable devices for lifting and lowering, such as a wedge-shaped lifting platform, etc., and there is no particular limitation here.

[0050] In some embodiments, as Figure 1 and Figure 2 As shown, the component fire resistance test device 100 also includes a second adjustment device (not shown), which is detachably arranged in the mounting groove 112 to adjust the size of the mounting groove 112. It can be understood that the size of the mounting groove 112 is adjusted by the second adjustment device so that the size of the mounting groove 112 can adapt to components 200 of different specifications. It should be noted that since the second adjustment device is arranged in the mounting groove 112 of the test furnace 1, the second adjustment device must have fireproof performance. Specifically in this embodiment, the second adjustment device can be fireproof cotton, which is sealed in the mounting groove 112 to adjust the size of the mounting groove 112. It can be understood that by sealing the remaining space of the mounting groove 112 around the component 200 with fireproof cotton, the size of the mounting groove 112 can be adjusted to adapt to different components 200. Of course, in other embodiments, the second adjustment device can be other suitable components that can adjust the space of the mounting groove 112, and there is no special limitation here.

[0051] In some embodiments, as Figure 1 and Figure 2 As shown, the test furnace 1 includes a furnace body 11 and a furnace cover 12; the furnace body 11 has a receiving cavity 111 with an opening at one end, the furnace cover 12 is detachably covered on the opening of the furnace body 11, and the side wall of the furnace body 11 is provided with a mounting groove 112. It can be understood that by providing the furnace body 11 and the furnace cover 12 detachably covered on the furnace body 11, when it is necessary to perform a fire resistance test on the wall, the furnace cover 12 is opened relative to the furnace body 11, and at the same time, the mounting groove 112 and other holes of the furnace body 11 are sealed with fireproof cotton, and the wall is erected at the opening of the furnace body 11, so that one side of the wall is exposed to fire and the other side is in a non-fire state. At this time, conventional performance tests such as compression and bending can be performed on the wall; when it is necessary to perform a fire resistance test on beams or columns, the furnace cover 12 is covered on the opening of the furnace body 11 to form a closed receiving cavity 111 for testing. Therefore, by providing a furnace body 11 and a furnace cover 12 that can be detachably covered on the furnace body 11 to form a test furnace 1, the test furnace 1 can be adapted to fire resistance tests of various components 200 such as beams, columns and walls, further improving the versatility of the component fire resistance test device 100 and reducing the test cost. In addition, it should be noted that the furnace cover 12 includes a cover body 121 and a closing piece 122. A through hole 1211 is provided on the cover body 121, so the closing piece 122 can be detachably covered on the through hole 1211 of the cover body 121, or the closing piece 122 can be rotatably covered on the cover body 121. It can be understood that by providing the through hole 1211 on the cover body 121, when the fire resistance test of the beam is carried out, the upper side surface of the beam only fits the lower surface of the cover body 121. In order to facilitate the external load to perform compression and bending performance tests on the beam, the closing piece 122 is removed or the closing piece 122 is opened to expose the through hole 1211. The external load can apply pressure to the beam body through the through hole 1211 to test the performance of the beam component.

[0052] In some embodiments, as Figure 2 As shown, the mounting groove 112 is formed recessed downward from the top of the furnace body 11 along the depth direction of the accommodating cavity 111. It is understandable that since the component 200 needs to be placed in the mounting groove 112 of the furnace body 11 during the fire resistance test, the mounting groove 112 is formed recessed downward from the top of the furnace body 11 along the depth direction of the accommodating cavity 111. This facilitates the insertion of the component 200 into the mounting groove 112 of the furnace body 11 from the top of the furnace body 11. Of course, in other embodiments, the mounting groove 112 can also be recessed from the middle or lower portion of the furnace body 11, and this is not particularly limited here.

[0053] In some embodiments, as Figure 1As shown, the component fire resistance test device 100 also includes a moving device 4, which is arranged on the support assembly 2 and is used to drive the furnace cover 12 to move in a three-dimensional space, thereby facilitating the opening or closing of the furnace cover 12, and facilitating the component fire resistance test device 100 to change the position of the furnace cover 12 relative to the furnace body 11 when performing fire resistance tests on different types of components 200; specifically, in this embodiment, the moving device 4 is a hoisting system, which can hook the furnace cover 12 to drive the furnace cover 12 to move in a three-dimensional space.

[0054] In some embodiments, as Figure 2 As shown, corresponding to one side of the mounting groove 112, the side wall of the furnace body 11 is provided with an observation window 113 connected to the accommodating cavity 111. Through the observation window 113, the status of the component 200 can be observed intuitively and in real time, which is convenient for the next step of operation; specifically, the observation window 113 can be square, circular, etc., and there is no special restriction here.

[0055] Based on the above-mentioned component fire resistance testing device 100, the present invention further provides a component fire resistance testing method, comprising the following steps:

[0056] S100, fix one end of the component 200 to the loading piece 22, and pass the other end of the component 200 through the two mounting slots 112 of the test furnace 1 and then fix it to another loading piece 22; wherein, the two ends of the component 200 are fixed by the two loading pieces 22 so that the component 200 can be hung in the mounting slot 112 of the test furnace 1.

[0057] S200, adjust the position of the loading member 22 relative to the supporting structure 21 and make the loading member 22 move along the depth direction of the accommodating cavity 111, so as to drive the component 200 connected with the loading member 22 to move to the preset position relative to the accommodating cavity 111; it is understandable that different types of components 200 have different fire exposure states, for example, a column is subjected to fire on all four sides of the column body, a beam is subjected to fire on three sides of the beam body and one side is not subjected to fire, etc. Therefore, according to the type of different components 200, by adjusting the position of the loading member 22 relative to the supporting structure 21 and making the loading member 22 move along the depth direction of the accommodating cavity 111, the loading member 22 can be adjusted to the preset position. The carrier 22 moves along the depth direction of the accommodating cavity 111, driving the component 200 connected to the carrier 22 to move to a preset position relative to the accommodating cavity 111. That is, the component 200 is adjusted to different positions in the depth direction of the accommodating cavity 111 so that the component 200 is in a suitable position for the fire resistance test. For example, the column is adjusted to the center position of the accommodating cavity 111 so that the four sides of the column are evenly exposed to the fire; the beam is adjusted to the top of the test furnace 1 so that the left and right sides and lower surfaces of the beam are evenly burned, while the upper surface of the beam is not exposed to the fire. It should be noted that in other embodiments, the component 200 can also be left stationary and the preset position of the component 200 in the accommodating cavity 111 can be adjusted by adjusting the height of the test furnace 1.

[0058] S300 , igniting the test furnace 1 , burning the component 200 and performing a performance test, such as a conventional bending performance test.

[0059] In summary, compared with the existing technology, this component fire resistance test method has at least the following beneficial effects:
