Support plates are inserted at the four corners of the two inner slots. The two outer frames have outer slots on their inner sides. The two outer frames are respectively fitted onto the four support plates on the left and four support plates on the right through the cooperation of the outer slots. The sealing body includes eight cover plates symmetrically distributed on the left and right sides of the inner frame. The four cover plates on the left are spliced ​​together and installed on the four support plates on the left. The four cover plates on the right are spliced ​​together and installed on the four support plates on the right. The outer walls of the cover plates are aligned with the outer walls of the inner and outer frames. The left and right ends of the cover plates abut against the inner and outer frames respectively.

[0007] Preferably, each of the support plates has two symmetrical support plate screw holes on both the left and right sides, and two symmetrical frame screw holes are provided at the four corners on both sides of the outer wall of the inner frame and at the four corners of the two outer frames. Each frame screw hole is screwed with a long bolt. The support plate is inserted into the corner of the inner frame by the cooperation of the long bolt and the frame screw hole with the support plate screw hole. Each outer frame is inserted into the four support plates by the cooperation of the long bolt and the frame screw hole with the support plate screw hole.

[0008] Preferably, each cover plate has four symmetrically arranged cover plate screw holes, and each support plate has four splicing screw holes on its outer wall corresponding to the position of the cover plate screw holes.

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0021] Example

[0022] Please see Figures 1-6This utility model discloses an assembled fire exhaust pipe, comprising an inner frame 1, two outer frames 4, and eight cover plates 6 symmetrically distributed on the left and right sides of the inner frame 1. The inner frame 1 has rounded corners at all four corners, and inner slots 2 are provided at both ends of the inner frame 1. Support plates 3 are inserted into the four corners of the two inner slots 2. Outer slots 5 are provided on the inner sides of the two outer frames 4, and the two outer frames 4 are respectively inserted into the four support plates 3 on the left and four on the right through the cooperation of the outer slots 5. The four cover plates 6 on the left are spliced ​​together and installed on the four support plates 3 on the left. The four cover plates 6 on the right are spliced ​​together and installed on the four support plates 3 on the right. The outer wall of the cover plate 6 is aligned with the outer wall of the inner frame 1 and the outer frame 4. The left and right ends of the cover plate 6 abut against the inner frame 1 and the outer frame 4 respectively. Two support plate screw holes 7 are symmetrically provided on both sides of the support plate 3. Two frame screw holes 8 are symmetrically provided at the four corners on both sides of the outer wall of the inner frame 1 and at the four corners of the two outer frames 4. Each frame screw hole 8 Each of the upper and lower support plates 6 is screwed with long bolts 9. The support plates 3 are inserted into the corners of the inner frame 1 through the cooperation of the long bolts 9 and the frame screw holes 8 and the support plate screw holes 7. Each outer frame 4 is inserted into the four support plates 3 through the cooperation of the long bolts 9 and the frame screw holes 8 and the support plate screw holes 7. Each cover plate 6 has four symmetrical cover plate screw holes 10. Each support plate 3 has four splicing screw holes 11 on its outer wall corresponding to the position of the cover plate screw holes 10. Each cover plate screw hole 10 is screwed with a short bolt 12. The cover plate 6 is installed on the support plate 3 by the cooperation of short bolts 12 with the cover plate screw holes 10 and splicing screw holes 11. In use, the main frame and sealing body are assembled to form a fire exhaust pipe. During transportation, the main frame and sealing body are disassembled and independent, that is, the inner frame 1, the support plate 3, the outer frame 4 and the cover plate 6 are all separate and can be stacked together for transportation. This greatly reduces the space occupied during transportation and makes transportation more convenient. After arriving at the site, they can be reassembled.

[0023] The inner frame 1, support plate 3, and cover plate 6 can be provided in multiple sets, with each set containing one inner frame 1, eight support plates 3, and a cover plate 6. When the pipe length is insufficient, it can be connected. To connect, simply remove the outer frame 4 on one side of the pipe, insert the inner frame 1 into the outer end of the support plate 3, then insert the support plate 3 into the inner slot 2, then splice and install the cover plate 6 on the support plate 3, and finally insert the outer frame 4 into the four outermost sets of support plates 3 to complete the pipe connection and lengthening.

[0024] Spring washers 13 are fitted onto both the frame screw hole 8 and the short bolt 12; by setting the spring washers 13, loosening can be effectively avoided after the frame screw hole 8 and the short bolt 12 are tightened.

[0025] The inner frame 1, support plate 3, outer frame 4, and cover plate 6 are all made of stainless steel; by using stainless steel, rust on the surface of the pipe can be avoided.

[0026] This utility model discloses a modular fire exhaust pipe. During transportation, the main frame and sealing body are disassembled and independent. The inner frame 1, support plates 3, outer frame 4, and cover plate 6 are all separate and can be stacked together for transport. The long bolts 9 and short bolts 12 can be packed in bags for transport, greatly saving transport space. Upon arrival at the destination, they can be assembled. During assembly, the support plates 3 are first inserted into the corners of the inner slots 2, and the four sets of support plates 3 are then secured sequentially using the long bolts 9. Finally, the outer frame 4 is inserted into the four sets of support plates 3. On the outside, the outer frame 4 is fixed to the support plate 3 with long bolts 9, thus completing the assembly of the main frame. After the main frame is assembled, the cover plate 6 is spliced ​​onto the four sets of support plates 3. The support plate 3 is a right-angled arc structure, and the upper and lower sides of the cover plate 6 are arc-shaped, with the arc being half the arc of the support plate 3. This allows the upper and lower sides of the cover plate 6 to fit with the support plate 3 after splicing, thus ensuring that adjacent cover plates 6 are in contact. Then, the cover plate 6 is fixed onto the four sets of support plates 3 in sequence with short bolts 12 to complete the overall assembly of the pipeline. With the support of the four sets of support plates 3, the overall strength of the pipeline can be guaranteed.

[0027] The present invention relates to a modular fire exhaust pipe, the installation method, connection method or setting method of which are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.
