[0002] With the introduction of three-dimensional layout of oil and gas field stations, a large number of ground pipelines need to be arranged on steel platforms or in steel-structured industrial plants. However, due to the different diameters and media of pipelines, the pipeline layout and direction are complicated, and the pipeline layout is difficult. For example, when arranging and fixing pipelines between the platforms or plant floors, when the pipeline diameter is small and the span is large, for example, the pipeline diameter is less than 0.1m and the span is greater than 6m, the pipeline is prone to bending and deformation during the layout process, which leads to the phenomenon that the pipeline cannot be arranged.

[0030] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] The present invention is used for a pipe support device of a steel structure project, such as Figure 1As shown, it includes pillars 1, and there are several pillars 1 and they are arranged side by side. A support beam is provided on the side wall of each pillar 1. There are several support beams, and the several support beams are evenly distributed along the axial direction of the pillar 1. By arranging the support beams and cooperating with the pillars 1, the support spacing when arranging the pipeline 4 can be effectively shortened, thereby facilitating the pipeline arrangement. The device has a simple structure, effectively reduces the amount of pillars 1, and then reduces the amount of support steel. While realizing large-span arrangement of pipelines with smaller diameters, the cost of pipeline support arrangement is saved.

[0032] The distance L between every two adjacent pillars 1 is not less than 6 m. A distance of not less than 6 m can reduce the number of pillars 1 used, reduce the amount of supporting steel, and save the cost of pipeline support layout.

[0033] A base is provided at the bottom of the support 1, and the support 1 is connected to the base by bolts. The base is also provided with a plurality of fixing holes, through which the support 1 is fixed. At the same time, the base can be fixed to the ground through the fixing holes.

A plurality of cross beams 3 are fixed to the longitudinal beam 2, and the cross beams 3 are perpendicular to the plane where the longitudinal beam 2 and the pillar 1 are located.

[0035] Stringer 2, such as Figure 2 As shown, a diagonal brace 7 is provided at both ends of the longitudinal beam 2. Each diagonal brace 7, the longitudinal beam 2 and the pillar 1 together form a triangular structure. The diagonal brace 7 supports the longitudinal beam 2. The extension length of the two ends of the longitudinal beam 2 from the pillar 1 is A, specifically:

[0036] A>L-6

[0037] Wherein, A: the extension length of both ends of the longitudinal beam 2 from the support 1, unit: m;

[0038] L: The distance between two adjacent pillars 1, unit: m.

[0039] The extension length of both ends of the longitudinal beam 2 from the support 1 is A, and A>L-6, which effectively shortens the span length when arranging the pipeline 4, so that the span of the pipeline 4 with a smaller diameter between two adjacent supports 1 is always less than 6m, thereby avoiding the phenomenon that the pipeline 4 with a smaller diameter is bent and deformed due to the long span.

[0040] Beam 3, such as Figure 3 As shown, the longitudinal beam 2 is provided with cantilevers on both the upper and lower sides, the cross section of the longitudinal beam 2 is U-shaped, and the cross beam 3 is fixedly connected to the top of the cantilever. The longitudinal beam 2 can reduce the spacing between the corresponding support beams on two adjacent pillars 1, effectively shortening the span length of the pipeline 4. And the cantilever lengths at both ends of the longitudinal beam 2 can be adjusted according to the column spacing of the pillars 1 and the allowable span of the pipeline 4.

[0041] A pipe clamp 5 is also provided on the cross beam 3, and the pipe clamp 5 is fixed to the cross beam 3 by bolts 6. The cross section height of the cross beam 3 is less than that of the longitudinal beam 2. A pipe 4 can be arranged on the cross beam 3, and the pipe clamp 5 can fix the pipe 4.

[0042] The cross-sectional height of the cross beam 3 is less than the cross-sectional height of the longitudinal beam 2. The cross-sectional height of the longitudinal beam 2 is as follows:

[0044] Wherein, h: cross-sectional height of longitudinal beam 2;

[0045] I x : Section moment of inertia;

[0046] The overall stability factor of the longitudinal beam 2;

[0047] f: design value of flexural strength of steel;
