Description

Technical Field

[0001] The present invention relates to the field of assembled integrated pipeline anti-seismic support and hanger, and in particular to an assembled integrated pipeline anti-seismic support and hanger and an installation method. Background Art

[0002] Integrated pipe supports and hangers are used to secure a building's supporting piping systems, such as water, heating, power, electricity, and process piping, to the main structure. They bear the weight of the pipes and ensure reliable connections during operation. Traditional supports and hangers are welded on-site, requiring extensive manual labor and multiple on-site installation steps. This makes it difficult to achieve convenient multi-layer piping arrangements, resulting in inconsistent quality. Welding also causes stress concentration, damages the original structure, and affects the coating and corrosion resistance. This slows installation and impacts costs and construction time.

[0003] After searching, the publication number CN113757452B disclosed an anti-seismic support and hanger for prefabricated buildings and a construction method, which belongs to the technical field of anti-seismic support and hanger. An anti-seismic support and hanger for prefabricated buildings and a construction method, including an assembly mechanism, a connector and a positioning mechanism; the assembly mechanism includes two clamping rings A and B that are closed into a ring, and a slide groove is provided in the clamping rings A and B, and a load-bearing component is provided in the slide groove, and the two load-bearing components are clearance-matched to form a pipeline installation cavity. In this application, the traditional pipeline anti-seismic support and hanger has obvious defects: the anti-seismic performance is single, and it cannot fully absorb and disperse energy under the action of complex seismic waves, the protection effect on the pipeline is poor, and the bolts and nuts are easy to loosen. Therefore, it is urgent to develop a new type of prefabricated integrated pipeline anti-seismic support and hanger and installation method to solve the above problems. Summary of the Invention

The thread design can automatically tap and lock when screwed in, without the need for additional nuts, reducing the gap problem caused by loose nuts. Secondly, a seismic monitor is installed on the seismic support and hanger to perform longitudinal seismic performance testing on the seismic support and hanger, and provide it to the intelligent network system to ensure that the deformation or load of the seismic support and hanger can be monitored and warned in a timely and accurate manner when a sudden change occurs.

[0005] In order to achieve the above-mentioned object, the present invention adopts the following technical solution: an assembled integrated pipeline seismic support and hanger and installation method, comprising a main seismic buffer mechanism and an auxiliary seismic buffer mechanism, wherein the upper end of the main seismic buffer mechanism is fixedly connected to a first seismic connecting member and the lower end is fixedly connected to a second seismic connecting member, the upper end of the auxiliary seismic buffer mechanism is slidably connected to a slider, the side of the slider is fixedly connected to an auxiliary spring, the end of the auxiliary spring away from the slider is fixedly connected to the seismic connecting piece, and the upper end of the seismic connecting piece is provided with a rear bottom anchor bolt;

[0069] G - The gravity of non-structural components, including the gravity of personnel involved in operation, media in containers and pipelines, and items in storage cabinets.

[0071]

[0072] Table: Maximum values of horizontal earthquake influence coefficients

[0073] earthquake impact 6 degrees 7 degrees 8 degrees 9 degrees Frequent earthquakes 0.04 0.08(0.12) 0.16(0.24) 0.32 rare earthquake 0.28 0.50(0.72) 0.90(1.20) 1.40

[0074] Note: The values in brackets are used for areas with design basic seismic acceleration of 0.15g and 0.30g respectively.

[0075] Calculate and verify the node diagram, taking 1 tube 1250×320 as an example:

[0076] Calculation of comprehensive coefficient of seismic force

[0077] α Ek =γηζ1ζ2α max

[0078] Where: αmax is based on the Appendix of the Code for Seismic Design of Buildings (GB 50011). The design basic earthquake acceleration value is 0.05g. Based on the frequent earthquake items in Table 3.3.5, the value is 0.04.

[0079] Because of the hanging or swinging lamps, water supply and drainage pipes, ventilation and air conditioning pipes and cable trays in Class A buildings, γ = 1.4, η = 0.9;

[0080] The node is a hanger, so: ζ1 = 1;

[0081] The node is located at the -1 floor (total height 13 floors), so ζ2 = 1.0;

[0082] Therefore: αEK=1.4×0.9×1.0×1.0×0.04=0.05<0.5

[0083] According to the specification requirements, take αEK = 0.5;

[0084] Standard value of earthquake horizontal force

[0085] According to the standard, the mass of a 1250×320 air duct is: 49kg / m

[0086] Standard value of earthquake horizontal force of lateral seismic supports and hangers:

[0087] F side = 0.5 × 9 × 49.0 × 9.8 / 1000 = 2.161 kN

[0088] Standard value of earthquake horizontal force of longitudinal seismic supports and hangers:

[0089] F vertical = 0.5 × 18 × 49.0 × 9.8 / 1000 = 4.322 kN

[0090] Design value of earthquake horizontal force

[0091] According to the requirements of the specification, the calculation should be carried out as follows:

[0092] S=γG S GE +γ EH S EHK ; Among them, the load partial coefficient is: γG=1.2; γEH=1.3;

[0093] Since this project does not consider the co-existence of seismic supports and hangers with gravity supports and hangers, S = γ EH S EHK

[0094] Design value of earthquake horizontal force of lateral seismic supports and hangers:

[0095] S1=γEHSEHK=1.3×2.16=2.81KN

[0096] Standard value of earthquake horizontal force of longitudinal seismic supports and hangers:

[0097] S2=γEHSEHK=1.3×4.32=5.62KN

[0098] Schematic diagram of the load on the vertical poles and longitudinal and transverse braces of the seismic support and hanger. N1 is the load on the seismic brace caused by the horizontal seismic load.

[0099] N2 is the force on the vertical pole caused by the horizontal earthquake load, N2 = S 1(2)

[0100] Therefore, the force on the lateral support bracket is N1=S1 / sin45°=2.81 / sin45°=3.97KN

[0101] The force on the lateral support bracket is N2=S1=2.81KN

[0102] Therefore, the longitudinal support bracket bears force, N1=S2 / sin45°=5.62 / sin45°=7.95KN

[0103] The vertical support and hanger pole is subjected to force: N2 = S2 = 5.62KN

[0104] Accessory force check

[0105] Table: Force verification of lateral support and hanger accessories

[0106] Table: Force verification of longitudinal support and hanger accessories

[0107]

[0108] This project uses seismic anchor bolts M12 / 18X110. When steel is damaged in cracked concrete, the design tensile force of a single M12 / 18X110 is 21.0KN and the shear force is 30.2KN. The most unfavorable force on the anchor bolt is the longitudinal bracing anchor bolt force. The anchor bolt verification calculation is as follows:

[0109] N=5.62÷2=2.81KN<21.0KN, the anchor bolt tensile strength meets the requirements;

[0110] N=5.62÷2=2.81KN<30.2KN, the anchor bolt shear resistance meets the requirements;

[0111] (2.81 / 21.0)2+(2.81 / 30.2)2=0.03<1.0, the tension-shear combined force meets the requirements;

[0112] Therefore, the anchor strength meets the requirements.

[0113] Example 3, reference Figure 1-5 As shown in the technical solution of the present invention, a prefabricated integrated pipeline seismic support and hanger and installation method are shown. The seismic support and hanger node calculation results show that the root connection member has a rated load of 49.497 kN. The pipe connection member has a rated load of 49.497 kN. Hanging specifications: M12 screw, maximum service load of the hanger rod: 32.8 kN, diagonal brace length: 1400 mm, diagonal brace vertical angle: 45°, minimum turning radius: 15 mm, L / R ratio: 93.333, and maximum horizontal bearing capacity of the diagonal brace: 37.1 kN. Specifications of the diagonal brace anchor bolts: M12 / 18X110, installation direction of the diagonal brace anchor bolts: top buried drill bit diameter: 18 (mm), effective anchoring depth: 80mm, installation torque: 45 (N*m), tensile bearing capacity: 21.0 (KN), shear bearing capacity: 30.2 (KN), overall safety partial factor y=1.4.

[0114] Working principle: First, according to the architectural design drawings and pipeline layout plan, use measuring tools to determine the installation position of the fixed base on the floor, wall or beam of the building, and mark it. Then, according to the properties of the double-locking anchor bolt 1 with an expanded bottom mechanical anchor bolt, one of the lower anchor points is to cut into the concrete by itself to achieve a locking key effect, and another is to use a special mold drill bit to pre-expand the hole and then install it to embed the expansion piece. It is fixed to the main shock-absorbing mechanism 4 through the rubber buffer pad 2 and the stainless steel spring sheet 15, and the rubber buffer pad 2 is fixed to the inside of the stainless steel spring 15. Use self-locking bolts to connect the two fixed splints and tighten them in the middle. Connect the connecting ear on one side of the fixed splint to the U-shaped slot of the lateral adjustment component or the connecting seat of the longitudinal adjustment component through pins and other connectors, and then the bottom end of the main buffer mechanism 4 is the same.

[0115] According to the longitudinal installation height of the pipeline, select the longitudinal adjustment hole at the appropriate position, pass the adjustment bolt through the longitudinal adjustment hole and mate it with the threaded hole of the connecting seat at the top of the longitudinal adjustment rod. By rotating the adjustment bolt, adjust the height of the longitudinal adjustment rod so that the connecting seat of the longitudinal adjustment rod is consistent with the installation height of the pipeline, and rotate it to connect it to the omnidirectional shock-absorbing mechanism 7. According to the lateral layout requirements of the pipeline, select the transverse adjustment hole at the appropriate position, pass the transverse adjustment rod through the transverse adjustment hole, and install locking nuts at both ends of the transverse adjustment rod. By adjusting the locking nuts, fix the position of the transverse adjustment rod and adjust its extension length so that the U-shaped slot of the transverse adjustment rod is aligned with the pipeline installation position. It also includes the auxiliary shock-absorbing mechanism 17 connected through the shock-absorbing head. Install the fixed base at the marked position using expansion bolts and other connectors to ensure that the fixed base is firmly connected to the building structure. Check whether the slide rails on the fixed base are horizontal or vertical. If there are any deviations, make adjustments. These shock-absorbing mechanisms are equipped with limit holes 18, limit slots 22 and slides 23. Then the main buffer mechanism 4 is connected to the support stretcher 11 through the vertical rod 3. The support stretcher 11 is similar in structure to the all-round shock-absorbing mechanism 7. The limit block 6 can be used to adjust according to the size of the rectangular bellows 21. The fixed base is installed in the marked position through expansion bolts and other connectors to ensure that the fixed base is firmly connected to the building structure. Check whether the slide rails on the fixed base are horizontal or vertical. If there are any deviations, make adjustments. Auxiliary springs 9 are provided inside the first seismic connection member 8 and the second seismic connection member 10 to relieve vibration pressure. Different from the traditional method, the nuts are deleted and replaced with self-locking bolts, which are convenient and quick. The slider 16 connected by the auxiliary spring 9 matches the slide 23. After completing the installation of all components, the assembled integrated pipeline seismic support and hanger are debugged and inspected as a whole. Check whether the connections between the components are firm and whether the adjustment bolts and lock nuts are tightened; check whether the pipelines are firmly fixed and whether there is any shaking or looseness; if there are any problems, adjust and repair them in time to adjust and fix the auxiliary shock-absorbing mechanism 17, and finally perform seismic testing to check whether the installation is successful.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
