The utility model discloses an upright post assembling structure applied to a photovoltaic shed, which comprises an upright post component and a connecting component, the upright post component is connected with a foundation structure through an embedded screw, the connecting component comprises a plurality of fasteners, and the upright post component is connected with the embedded screw through the fasteners so as to realize non-welding type assembling. According to the utility model, non-welding type assembly is realized by connecting the upright post component and the pre-embedded screw rod through the fastener, the traditional welding process is replaced, the potential quality hazards such as weld pores and cracks caused by severe field welding operation environment and technical level difference of welders are eliminated, and the structural strength of the connecting part is stable and reliable. A standardized fastener connection mode is adopted, a common constructor can quickly complete the installation operation without professional welding equipment and certified welders, the site construction intensity and construction difficulty are greatly reduced, the installation efficiency is improved, and when the height or angle needs to be adjusted, the fastener is convenient to assemble and disassemble.

The application discloses a node combined beam assembling method, optimizes the port form of the node combined beam, and changes the upper flange plate of the port to be short, the lower flange plate to be long and the middle web plate to be vertical and in the middle of the node combined beam in the deck piece land prefabrication stage. The upper flange plate of the port to be installed is short, the lower flange plate is long and the middle web plate is long, and the whole is in the form of an inverted "convex character" port. In the deck piece land prefabrication stage, the upper flange plate of the port is changed to be long, the lower flange plate is changed to be short and the middle web plate is changed to be vertical and in the middle. When the node combined beam to be installed is hoisted in the air, the original horizontal hoisting insertion hole mode is optimized to be a vertical hoisting seat bottom type, and then the splicing joint assembling and welding work is completed. The application is convenient for on-site command hoisting and positioning, reduces construction strength, improves hoisting efficiency and improves construction precision.

The application discloses a construction method of a road and bridge safety guardrail, and comprises the following steps: (a) marking a construction area; (b) installing a first cross beam between two stand columns to obtain a stand column combination; (c) installing a buffer cylinder between two stand column combinations; (d) butting a second cross beam with a connecting seat, and then installing the connecting seat on the first cross beam; (e) butting the second cross beam with two adjacent connecting seats; (f) fixing the stand column in place; (g) installing on the second cross beam; (h) locking a first anti-glare plate; and (i) installing a limiting rod between two adjacent anti-glare plates. The application has the advantages of simple construction, small quantity of bolts, low operation difficulty, low labor intensity, high construction efficiency, step-by-step order, guaranteed assembly quality of the guardrail, reliable and effective light blocking wall formed by the anti-glare plates, difficult penetration of light of an opposite vehicle, good light blocking effect, and solved problem of opposite vehicle light glare.

The application provides a large-diameter steel pipe column top-down method verticality control device and a use method. The device comprises a connecting ring seat arranged on the ground and located outside the pile hole, and an operation seat arranged on the connecting ring seat and used for connecting with the upper end of the steel pipe column and leveling the upper end of the steel pipe column. The verticality of the lower end of the steel pipe column does not need to be adjusted manually, the construction efficiency is greatly improved, the construction intensity of the construction personnel is greatly reduced, the economy is improved, the construction period can be ensured, the safety hidden danger is reduced, the stability is improved, the verticality of the steel pipe column is not easily interfered with when the device is recovered after the verticality of the steel pipe column is adjusted, the verticality of the steel pipe column is not easily reduced, the device is not easily caused to fall, the verticality of the steel pipe column can be quickly adjusted, and the verticality precision is improved.
