Description

Technical Field

[0001] This utility model relates to the technical field of fire protection installation, and in particular to a non-welded support for fire protection pipelines. Background Technology

[0002] The fire protection piping system in steel structure engineering, especially the design and construction technology of its support structure, plays a crucial role in ensuring the safety and reliability of the building. Traditional fire protection piping construction technology relies on welding methods, which have many problems, including long construction cycles, high costs, safety hazards, and high requirements for the construction environment. More importantly, welding may damage the steel structure itself, affecting the overall safety performance of the building.

[0003] Non-welded modular supports, as a novel type of fire-fighting pipeline support structure, have attracted widespread attention due to their advantages such as convenient construction and minimal structural damage. However, although this type of support solves some of the problems of traditional welding technology, its structural form, assembly method, and seismic performance still have shortcomings, requiring further technological innovation and standardization. Therefore, a steel structure fire-fighting pipeline fixing support that avoids welding is needed. Utility Model Content

[0004] The purpose of this utility model is to solve the above problems and provide a non-welded support for fire protection pipelines.

[0005] The technical solution of this utility model is: a non-welded support for fire protection pipelines, through which fire protection pipelines are installed at the bottom of flanged steel sections, and the support is provided with several of them; the support includes a crossbeam; the crossbeam abuts against the bottom surface of the flanged steel section base plate, and the two ends of the crossbeam are respectively fixed to the two flanges of the bottom of the flanged steel section by clamping components; the crossbeam is set perpendicular to the flanged steel section, and the two ends of the crossbeam extend beyond the side of the flanged steel section; the bottom of the crossbeam is provided with several through holes A, and the through holes are evenly arranged along the length direction of the crossbeam;

[0006] The bracket also includes a support rod, with a through hole B at each end of the support rod. Through hole B and through hole A are fixed together by studs.

[0007] Preferably, the through hole B is an oblong hole, which facilitates the adjustment and fixation of the support rod.

[0008] Preferably, the bracket also includes pads; there are two pads, both of which are disposed on the upper surface of the flanged steel base plate; the two pads correspond to the two ends of the crossbeam respectively;

[0009] The support structure also includes U-bolts and connecting plates; the connecting plates have through holes C at both ends; the connecting plates are positioned on top of the base plate; the two ends of the U-bolts pass through the through holes C on both sides of the crossbeam and are secured with nuts. The U-bolts fix the crossbeam and the base plate together and clamp them onto the flanged steel base plate, thereby fixing the support structure to the building's steel structure in a non-welding manner.

[0010] Furthermore, the crossbeam is a C-shaped channel steel with its opening facing upwards. A support block is installed inside the channel of the crossbeam, and the top of the support block abuts against the bottom of the pad. The support block supports the pad, ensuring that the U-bolts stably fix the pad and the crossbeam.

[0011] Preferably, a spring damper is provided in the middle of the stud; the stud includes an upper stud and a lower stud; the top of the upper stud is connected to the crossbeam by a nut, and the bottom is fixed to the upper connecting end of the spring damper by a threaded engagement; the top of the lower stud is fixed to the lower connecting end of the spring damper by a threaded engagement, and the bottom is fixed to the support rod by a nut. The spring damper can absorb vibration and prevent the fire pipeline from transmitting vibration to the steel structure of the building.

[0012] Preferably, several brackets are evenly arranged along the length of the flanged steel section. The evenly arranged brackets support the fire-fighting pipelines and secure them in place.

[0013] Preferably, a pad is provided at the bottom of the crossbeam, and the bottom of the pad is in contact with the fire protection pipeline. This avoids rigid contact between the fire protection pipeline and the crossbeam and can absorb some of the vibration of the fire protection pipeline, thereby preventing the vibration of the fire protection pipeline from being transmitted to the steel structure of the building.

[0014] Preferably, two flanged steel sections are arranged side by side, with the fire protection pipeline intersecting the flanged steel sections; the direction of the support rod is perpendicular to the direction of the fire protection pipeline; the through holes at both ends of the support rod are respectively connected to the two crossbeams via studs. By adjusting the corresponding through holes A on the two crossbeams, the deflection angle of the support rod can be adjusted, thereby cooperating with the fire protection pipeline.

[0015] Furthermore, a pad is provided at the bottom of the flanged steel section, with the bottom of the pad in contact with the fire protection pipeline. This prevents the fire protection pipeline from making rigid contact with the flanged steel section and absorbs some of the vibration of the fire protection pipeline, thereby preventing the vibration of the fire protection pipeline from being transmitted to the steel structure of the building.

[0029] Example 1: See Figure 1-4A non-welded bracket for a fire-fighting pipeline 01 is provided. The fire-fighting pipeline 01 is installed at the bottom of a flanged steel section 00 via the bracket. In this embodiment, the flanged steel section 00 is an I-beam. The bracket is provided with several sections. The bracket includes a crossbeam 11. The crossbeam 11 abuts against the bottom surface of the base plate of the flanged steel section 00. The two ends of the crossbeam 11 are fixed to the two flanges at the bottom of the flanged steel section 00 by clamping components. The crossbeam 11 is perpendicular to the flanged steel section 00, and the two ends of the crossbeam 11 extend beyond the sides of the flanged steel section 00. The bottom of the crossbeam 11 is provided with several through holes A111, which are evenly distributed along the length of the crossbeam 11.

[0030] The bracket also includes a support rod 19, with a through hole B at each end of the support rod 19. The through hole B and the through hole A 111 are fixed together by studs.

[0031] The through hole B is an oblong hole, which facilitates the adjustment and fixation of the support rod 19.

[0032] The bracket also includes pads; there are two pads, both set on the upper surface of the flanged steel 00 base plate; the two pads correspond to the two ends of the crossbeam 11 respectively;

[0033] The bracket also includes U-bolts 14 and connecting plates 15; the connecting plates 15 have through holes C191 at both ends; the connecting plates 15 are located on top of the base plate; the two ends of the U-bolts 14 pass through the through holes C191 on both sides of the crossbeam 11 and are fixed with nuts. The U-bolts 14 fix the crossbeam 11 and the base plate to each other and clamp them onto the flanged steel 00 base plate, thereby fixing the bracket to the steel structure of the building in a non-welding manner.

[0034] The crossbeam 11 is a C-shaped channel steel with its opening facing upwards. A support block 13 is installed inside the channel of the crossbeam 11, and the top of the support block 13 abuts against the bottom of the pad. The support block 13 supports the pad and ensures that the U-bolt 14 stably fixes the pad and the crossbeam 11.

[0035] A spring damper 18 is installed in the middle of the stud; the stud includes an upper stud 16 and a lower stud 17; the top of the upper stud 16 is connected to the crossbeam 11 by a nut, and the bottom is fixed to the upper connecting end of the spring damper 18 by a threaded engagement; the top of the lower stud 17 is fixed to the lower connecting end of the spring damper 18 by a threaded engagement, and the bottom is fixed to the support rod 19 by a nut. The spring damper 18 can absorb vibration and prevent the fire pipeline 01 from transmitting vibration to the steel structure of the building.

[0036] Several brackets are evenly arranged along the length of the flanged steel section 00. The fire protection pipeline 01 is placed on the brackets and fixed in place.

[0037] A pad 2A is installed at the bottom of the crossbeam 11, and the bottom of the pad 2A is in contact with the fire protection pipeline 01. This prevents the fire protection pipeline 01 from making rigid contact with the crossbeam 11 and can absorb some of the vibration of the fire protection pipeline 01, thereby preventing the vibration of the fire protection pipeline 01 from being transmitted to the steel structure of the building.

[0038] The working process of this embodiment includes the following steps:

[0039] ① Place the pad on the flanged steel 00 base plate, and install the crossbeam 11 below the pad accordingly. Then tighten and fix it with U-bolts 14.

[0040] ② The top ends of the two upper studs 16 extend into the through holes A 111 at both ends of the crossbeam 11 and are fixed with nuts;

[0041] ③ Connect the two spring shock absorbers 18 to the bottom ends of the two upper studs 16 respectively;

[0042] ④ The bottom of the two spring shock absorbers 18 is connected to the lower studs 17 respectively. The bottom of the lower studs 17 passes through the through holes B at both ends of the support rod 19 and is fixed with nuts.

[0043] ⑤ Repeat steps ①-④ to install multiple brackets;

[0044] ⑥ Raise the fire pipeline 01 so that its height is slightly higher than the height of the support rod 19;

[0045] ⑦ Insert the fire-fighting pipeline 01 between the support rod 19 and the crossbeam 11 of the bracket;

[0046] ⑧ After the fire pipeline 01 section is fully inserted, place the fire pipeline 01 on the support rod 19;

[0047] ⑨ Tighten the nut at the bottom of the support rod 19 to gradually raise the support rod 19 until the fire pipeline 01 and the crossbeam 11 are close;

[0048] ⑩ Install pad 2 between fire pipeline 01 and crossbeam 11; the bracket installation is complete.

[0049] Example 2: See Figure 5-8 Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that there are two flanged steel sections 00, and the fire pipeline 01 is arranged intersecting with the flanged steel sections 00; the direction of the support rod 19 is perpendicular to the direction of the fire pipeline 01; the through holes B at both ends of the support rod 19 are respectively connected to the two crossbeams 11 through studs. By adjusting the through holes A 111 corresponding to the studs on the two crossbeams 11, the deflection angle of the support rod 19 can be adjusted, thereby cooperating with the fire pipeline 01.

[0050] A pad 2B is installed at the bottom of the flanged steel section 00, and the bottom of the pad 2B is in contact with the fire protection pipeline 01. This prevents the fire protection pipeline 01 from making hard contact with the flanged steel section 00 and can absorb some of the vibration of the fire protection pipeline 01, thereby preventing the vibration of the fire protection pipeline 01 from being transmitted to the steel structure of the building.
