Description

Technical Field

[0001] This utility model belongs to the field of underground engineering construction, and in particular relates to a fire-receiving device for protecting the waterproofing of large-volume concrete in subway stations. Background Technology

[0002] In underground engineering construction, waterproofing has a significant impact on structural quality. Therefore, ensuring proper waterproofing construction and protection of underground structures is a key focus, especially in subway station construction. Welding or cutting operations are often performed on both sides of the steel supports of the retaining structure. During these operations, the large volumes of concrete below are already waterproofed. Sparks from welding or cutting can easily ignite and damage the waterproofing material, compromising its effectiveness and compromising the quality of the subsequent project. Currently, it is difficult to secure welding torches when welding or cutting large volumes of concrete in subway stations. Fixing the torch to the concrete wall can easily damage the wall structure and prevents it from moving with changes in construction location, making practical operations very inconvenient. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a fire-receiving bucket device for protecting the waterproofing of large-volume concrete in subway stations.

[0004] This invention is achieved through the following technical solution: A fire-receiving device for protecting the waterproofing of large-volume concrete in subway stations includes a fire-receiving bucket. Two vertical connecting rods are symmetrically welded upwards on one side of the fire-receiving bucket. A horizontal sleeve is welded to the upper end of the vertical connecting rods, and a horizontal connecting rod passes through the horizontal sleeve. Magnets are fixed at both ends of the horizontal connecting rods. Embedded steel plates are provided at the welding or cutting positions on both sides of the steel support of the enclosure structure, and the magnets can be attracted to the embedded steel plates. The horizontal sleeve is provided with a threaded hole B, and a bolt B is screwed into the threaded hole B to fix the horizontal sleeve to the horizontal connecting rod.

[0005] Preferably, the length of the transverse connecting rod is 2-4m.

[0006] Preferably, the outer surface of the embedded steel plate is flush with the concrete wall surface.

[0007] Preferably, the vertical connecting rod includes a vertical adjusting rod and a vertical fixing rod sleeved together. The vertical adjusting rod can slide up and down inside the vertical fixing rod. The vertical fixing rod has a plurality of threaded holes A from bottom to top. Bolts A are screwed into the threaded holes A, and the vertical fixing rod and the vertical adjusting rod are fixed together by the bolts A.

[0008] Preferably, the vertical connecting rod includes a vertical adjusting rod and a vertical fixing rod sleeved together. The vertical adjusting rod can slide up and down inside the vertical fixing rod. Both the vertical fixing rod and the vertical adjusting rod are provided with several corresponding adjusting holes, which all penetrate the vertical fixing rod and the vertical adjusting rod. The vertical adjusting rod and the vertical fixing rod are fixed together by bolts passing through the adjusting holes.

[0009] Preferably, a transverse reinforcing bar is welded between the vertical connecting rods.

[0010] This invention features a pre-embedded steel plate at the steel support of a large-volume concrete enclosure structure in a subway station. A fire-catching device is installed near the steel support by attaching it to the pre-embedded steel plate with a magnet. During welding or cutting operations, the fire-catching device can be moved according to the work position, which not only protects the waterproofing below from damage but also allows for flexible adjustment of its position, making it highly practical.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0014] This embodiment includes a welding hopper 1, which can be a conventional welding hopper for high-altitude welding operations. Two vertical connecting rods are symmetrically welded upwards on one side of the welding hopper 1, and a horizontal reinforcing rod 12 is welded between the vertical connecting rods. A horizontal sleeve 2 is welded to the upper end of the vertical connecting rods, and a horizontal connecting rod 3 passes through the horizontal sleeve 2. The horizontal sleeve 2 can slide left and right along the horizontal connecting rod 3, and the position of the welding hopper 1 below can be adjusted by sliding the horizontal sleeve 2. Preferably, the length of the horizontal connecting rod 3 is 2-4m. Magnets 4 are fixed at both ends of the horizontal connecting rod 3. The magnets 4 are used to adhere to the wall surface of the enclosure structure. To cooperate with the magnets 4, a pre-embedded steel plate 5 is installed in the wall surface of the enclosure structure in advance during the construction of the enclosure structure. The position of the pre-embedded steel plate 5 is set at the welding or cutting positions on both sides of the steel support. The length and width of the pre-embedded steel plate 5 are set according to the needs of the welding or cutting operation. The outer surface of the pre-embedded steel plate 5 embedded in the concrete wall surface is flush with the concrete wall surface, and the magnets 4 can adhere to the pre-embedded steel plate 5.

[0015] The aforementioned transverse sleeve 2 is provided with a threaded hole B6, and a bolt B7 is screwed into the threaded hole B6. By tightening the bolt B7, the transverse sleeve 2 can be fixed on the transverse connecting rod 3, so that the transverse sleeve 2 can no longer slide along the transverse connecting rod 3.

[0016] The vertical position of the preferred fire-receiving bucket 1 is also adjustable. This invention sets the vertical connecting rod as a telescopic structure. The vertical connecting rod can directly adopt a conventional extension rod with a snap-lock stop, or other telescopic structures can be used. In this embodiment, the preferred vertical connecting rod includes a vertical adjusting rod 8 and a vertical fixing rod 9 sleeved together. The vertical adjusting rod 8 can slide up and down within the vertical fixing rod 9, adjusting the total length of the vertical connecting rod. The lower end of the vertical adjusting rod 8 is welded to the fire-receiving bucket 1, and the upper end of the vertical fixing rod 9 is welded to the transverse sleeve 2. The fixing structure between the vertical adjusting rod 8 and the vertical fixing rod 9 can take various forms; this invention does not impose any special limitations. Two simple fixing structures are given in this embodiment, as described below: First type of fixed structure: as shown in the attached document. Figure 3 As shown, several threaded holes A10 are provided on the vertical fixing rod 9 from bottom to top. Bolts A11 are screwed into the threaded holes A10. By tightening the bolts A11, the vertical fixing rod 9 and the vertical adjusting rod 8 can be fixed together. The number of threaded holes A10 and bolts A11 can be selected according to the actual situation, as long as it can ensure that the vertical adjusting rod 8 and the vertical fixing rod 9 no longer slide relative to each other.

[0017] The second type of fixed structure: as shown in the attached document. Figure 4As shown, several corresponding adjustment holes 13 are provided on both the vertical fixed rod 9 and the vertical adjusting rod 8. The adjustment holes 13 all pass through the vertical fixed rod 9 and the vertical adjusting rod 8. The vertical adjusting rod 8 and the vertical fixed rod 9 are fixed together by bolts passing through the adjustment holes 13.

[0018] During construction, first, according to the work location, attach the magnets 4 at both ends of the horizontal connecting rod 3 to the appropriate positions on the pre-embedded steel plate 5. Slide the horizontal sleeve 2 to adjust the left and right positions of the lower fire-receiving bucket 1. After adjustment, tighten bolt B7 so that the horizontal sleeve 2 can no longer slide along the horizontal connecting rod 3. Then, slide the vertical adjusting rod 8 to adjust the up and down position of the fire-receiving bucket 1. After adjustment, tighten bolt A11 or pass a bolt through the adjusting hole 13 to prevent the vertical adjusting rod 8 from sliding up and down. Once everything is adjusted, high-altitude welding can be performed. The fire-receiving bucket 1 prevents sparks from splashing onto the pre-done waterproofing below, thus avoiding damage to the waterproofing caused by welding. During welding, as the welding position moves, the horizontal sleeve 2 can be slid to adjust the position of the fire-receiving bucket 1. After welding at this position is completed, attach the device to another pre-embedded steel plate 5 to continue the work. Once all welding work on this layer is completed, normal waterproofing can be carried out on the wall surface where the embedded steel plate 5 is located. Move the device to the embedded steel plate 5 on the next layer and continue the welding work. The device protects the waterproofing below. This process can be repeated from bottom to top until all welding work is completed.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
