[0026] Top I-beams 1-1, there are two top I-beams 1-1, which are connected and fixed by a detachable connecting plate 1-2 and bolt assemblies;

[0027] Diagonal bracing I-beams 1-3, there are two diagonal bracing I-beams 1-3, which are fixed inwardly at the bottom of the two top I-beams 1-1; and the bottom ends of the two diagonal bracing I-beams 1-3 are fixedly connected by a bottom I-beam 1-4; sealing edges 1-7 are arranged between the two flange plates of the bottom I-beam 1-4, and a reinforcing I-beam 1-8 is connected between the inner ends of the diagonal bracing I-beam 1-3 and the top I-beam 1-1;

[0028] Bottom connecting steel plate 1-5, the bottom connecting steel plate 1-5 is fixed to the bottom of the bottom I-beam 1-4; diagonal bracing reinforcement plates 1-6 are fixed in the two groove surfaces of the diagonal bracing I-beam 1-3, the top end of the diagonal bracing reinforcement plate 1-6 is fixed to the top I-beam 1-1, and the bottom end is fixed to the bottom connecting steel plate 1-5; several bottom reinforcement plates 1-10 are fixed between the bottom connecting steel plate 1-5 and the bottom I-beam 1-4; the vertical sides of the bottom reinforcement plates 1-10 are fixed to the sealing edges 1-7;

[0029] Steel plate positioning grooves 1-9, there are three steel plate positioning grooves 1-9, which are respectively fixed on the two top I-beams 1-1 and the bottom I-beam 1-4.

[0030] The manufacturing and installation method of the present utility model is as follows:

[0031] 1. Laser cutting method is adopted for plate cutting to ensure consistent dimensions. Each finished plate after cutting and forming needs to be clearly marked;

[0032] 2. For pipe and section steel cutting, use a cold saw. For welding rods, use E55 and above. Just do surface grinding and no paint is required.

[0033] 3. After the manufacturer finishes production, transport it to the site. Use a tower crane to assist in installation. First, install the bottom anchor support 4. After positioning, mark the position of the rear anchor bolts and drill holes to implant M20 mechanical anchor bolts. Then lift the bottom anchor support 4 and align it with the mechanical anchor bolts. After calibrating with a level, tighten the screws. Use double nuts. For uneven parts at the bottom, use steel plates to level. After all installations are completed, fill it with 1:1 cement mortar.

[0034] 4. Next, install the middle fixed support 3. After lifting, align it with the upper and lower connecting plate holes and insert M20-8.8 grade bolts and tighten them. Then hoist the upper adjusting support 2 for the installation of the previous section. The installation is similar to that of the standard section.

[0035] 5. Before installing the top support 1, measure the elevation. Since the dimensions have been considered not to be too high during production and all are on-site measurement data, it is generally a little lower. According to the actual situation, use shims to add and level the height. After the elevation is satisfied, hoist the top support slowly and align it with the bolt holes, insert M20-8.8 grade bolts and tighten them.

[0036] 6. In the design of this support structure, it is considered that the independent stability can meet the construction requirements without using any bracing. However, for greater safety in case of any eventuality, a steel bar tie rod 5 is set to increase safety measures. Hoist the first section of the pipe truss main beam into the top support 1. At this time, remove the detachable connecting plate 1-2 in the middle of the top support 1. After the pipe is placed in the top support 1, the installation of the detachable connecting plate 1-2 can be restored and the bolts are tightened to make them an integral whole. Next, hoist the 2 main pipes at the top. After adjusting the elevation, the middle struts can be welded. Since the main pipes are 12 meters long, a strut is welded every about 3 meters. After all welding is completed, this support structure can be removed and reused for the installation of the next truss support, saving materials.

[0037] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model provides a tool rack type support structure for on-site welding and installation of a roof pipe truss, which is segmented and adjustable, fabricated in the factory and assembled on-site, facilitating construction, and can be reused by simply changing the length of the upper adjusting section.

[0038] For those skilled in the art, they can modify the technical solutions recorded in the foregoing embodiments and perform equivalent replacements of some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
