Nowadays, when pre-embedding anchor bolts, there is no uniform and standard positioning mold. Usually, a large number of disposable woodworking boards are used as positioning molds for pre-embedding anchor bolts. Although the cost of woodworking boards is low, due to Can not be reused, resulting in waste of materials, and the positioning mold production cycle is long, affecting the progress of embedded construction, while the use effect is poor, and the embedded accuracy of anchor bolts is not easy to guarantee
In addition, in the actual pre-embedded construction of anchor bolts, there is no uniform, standard and reasonable construction method to follow. The construction period is difficult to be guaranteed

Embodiment Construction
[0057] like figure 1 The shown one-time construction method of pre-embedded anchor bolts in steel structure buildings, the number of pre-embedded anchor bolts 1 is N, and the N anchor bolts 1 are all buried in the concrete foundation of the steel structure building to be constructed Inside, the diameters of the N anchor bolts 1 are not greater than 50mm and they are arranged vertically, wherein N is a positive integer and N≥4. A layer of concrete cushion is arranged at the bottom of the concrete foundation, and both the concrete foundation and the concrete cushion are arranged horizontally. The concrete foundation is a reinforced concrete structure and a reinforcement cage is arranged inside it. When constructing a plurality of said anchor bolts 1, the process is as follows:
[0058] Step 1. Grouping of anchor bolts: According to the embedding positions of the N anchor bolts 1 in the concrete foundation, the N anchor bolts 1 are divided into M groups, and the anchor bolts 1 ...

The invention discloses a steel structure building construction method for pre-burying of foundation bolts. The steel structure building construction method comprises the following steps: 1. grouping of the foundation bolts: all the foundation bolts to be pre-buried are divided into a plurality of groups, the groups of the foundation bolts are respectively distributed in a plurality of bolt pre-burying areas in a concrete foundation, and the foundation bolts in each group form a bolt group; 2. grouped assembly of the foundation bolts: the bolt groups are respectively assembled, and the assembly procedure comprises manufacturing of a positioning mold, inserting of the foundation bolts, fixing of the foundation bolts, and separating of the bolt groups from positioning mold; 3. concrete cushion construction and pre-burying of fixing steel bars; 4. lower part fixing of the bolt groups; 5. binding of the steel bars and support arrangement of a template erection in the concrete foundation; 6. a position adjustment and upper part fixing of the bolt groups; 7. concrete foundation pouring. The method provided by the invention is simple in procedure, reasonable in design, convenient in implementation, and good in use effects, and has the advantages that the construction process for the high-precision pre-burying of the foundation bolts in the concrete foundation can be simply, conveniently and rapidly completed with high quality.
Description
technical field [0001] The invention belongs to the technical field of anchor bolt construction, and in particular relates to a one-time construction method for pre-embedded anchor bolts in a steel structure building. Background technique [0002] In recent years, with the rapid development of my country's national economy, various steel structure buildings have become more and more popular among users, such as various steel structure workshops, long-span bridges and various steel grid buildings. Compared with traditional reinforced concrete buildings, steel structure buildings have the characteristics of fast construction, small limitations, and high recovery rate. With the wide application of steel structure buildings, the installation accuracy of steel support columns and anchor bolts of steel structure buildings has gradually become a key process of construction. The one-time pre-embedding of anchor bolts poses a great challenge to construction. Nowadays, when pre-embed...
