Description

Angle steel tower reinforcing apparatus of mosaic structure

Technical Field

The utility model relates to the technical field of angle steel tower reinforcement, in particular to an angle steel tower reinforcement device with a splicing structure.

Background

At present, two methods for reinforcing the angle steel tower are mainly adopted. Firstly, through modes such as adding auxiliary materials or transverse planes, the section calculation graph is changed, so that the stress mode of the angle steel tower part structure is changed, and the reinforcement effect is achieved. The method has the advantages of high construction difficulty and less application. And secondly, reinforcing devices are added on the original tower materials to form a new section form, so that the diagonal steel tower is reinforced. The method has a cross-shaped, Z-shaped, T-shaped, C-shaped and other various forms on the section, and has welding type, bolt type and other connecting modes on the connecting modes, and the method is commonly applied to reinforcing angle steel towers, but still has the defects. The method for adding the reinforcing device on the original tower material is that angle steel with the same specification as the original tower material is adopted, the new angle steel is parallel to the original tower material and keeps a certain gap, and the original tower material and the new angle steel are connected in parallel by bolts through a connecting component, so that rigid connection between the original tower material and the new angle steel is realized, and a new tower material section form is formed. The stress of the original tower material is transmitted to the new angle steel through the connecting component, the new angle steel can bear the stress together with the original tower material and share the load, the stress of the original tower material is reduced, and the structure is reinforced. The reinforcing method can reinforce the diagonal steel tower, but needs to open bolt holes on the original angle steel tower, so that the original angle steel tower is easy to damage, the high-altitude drilling difficulty is high, and in addition, the reinforcing structure and the original angle steel tower structure interfere due to the fact that the diagonal steel tower structure is not fully considered, so that the construction difficulty is improved. To the above-mentioned problem that exists, it is very necessary to study and design a novel angle steel tower reinforcing apparatus of mosaic structure, overcome the problem that exists in the reinforcing of current angle steel tower.
