Column shoe bolt assembling and positioning device and construction method thereof

Abstract

The invention provides a column shoe bolt assembling and positioning device and a construction method thereof. The column shoe bolt assembling device comprises a steel pipe portal frame I and an elevation positioning plate, wherein the elevation positioning plate and a steel bar bag are respectively arranged on the upper and lower parts of the steel pipe portal frame I, a plurality of column shoe bolts are evenly arranged in the steel bar bag, the upper parts of the column shoe bolts extend out of the steel bar bag and penetrate through bolt holes in the elevation positioning plate to be fixedly connected with the elevation positioning plate, a set distance is formed between the top end surface of the column shoe bolt and the upper end surface of the elevation positioning plate, and the lower parts of the column shoe bolts are fixedly connected with the steel bar bag through additional steel bars. According to the column shoe bolt assembling and positioning device, the main body structure can be completed only by connecting hollow steel pipes through cross fasteners, local materials can be used, the increment cost is basically avoided, and the assembly and manufacturing are simple; and independent foundation column shoe bolts and raft foundation column shoe bolts can be assembled, positioned and fixed, the universality is high, the operation is simple, and the efficiency is high.

Description

Technical field [0001] The present invention relates to the field of assemblies, in particular, relate to a column shoe bolt assembly and a positioning device and a construction method thereof. Background technique [0002] Bolt connections are commonly used in assembled buildings. For example, between the prefabricated column and the foundation, the bolt bolts are connected to the base, and the column booth is embedded in the foundation, and the column shoe is effectively connected to the upper structure and the lower basis. It plays a role in which the column is loaded, such as shaft force, bending moment, and shear to reinforced concrete. The embedding accuracy of the column shoe bolt directly affects the installation accuracy of the prefabricated member to the installation quality of the entire assembled structure, and if an incomplete error can cause rework, waste, time delay, etc., therefore precise positioning column boots bolts The construction quality of the position and...

Problems solved by technology

However, this method cannot guarantee the stability of the installation position of the column shoe bolts, and the workload of setting out the wires is large

At present, there is also a method of placing the column shoe bolts in the assembly fixture to fix them as a whole and then transport them to the construction site for installation, but there are disadvantages such as inconvenient transportation, high transportation costs, and easy loose skeletons, and because the column shoe bolts fix the components If it is not assembled at the construction site, it may not be able to adapt to the complex construction site environment and construction deviation, so that the precise positioning of the plane position and elevation of the column shoe bolts cannot be fully guaranteed

At the same time, different foundation types also have a great influence on the positioning of the column shoe bolts. For example, the positioning of the column shoe bolts of the raft foundation is different from that of the independent foundation. The column shoe bolt positioning of the independent foundation can use the foundation side form as the column shoe The bolt elevation support and the datum of the control axis are relatively easy to realize the positioning and fixing of the plane position and elevation of the column shoe bolts, while the raft foundation column shoe bolts are relatively difficult to locate because there is no foundation side form as a datum and support. There are obvious differences in the positioning and fixing of shoe bolts

In addition, some existing column shoe bolt positioning molds need to be specially designed, customized, and produced, and the versatility is not strong, resulting in waste of materials and relatively high cost
