Embodiment Construction

[0010] like figure 1 , 2 As shown in the figure, a construction process for connecting steel beams without steel columns includes the following steps: firstly make a steel beam 2, drill holes for tension bolts on the steel beam 2 to reinforce the formwork, and then make a pass through the middle of the concrete column The straight thread head of the steel bar 18 upper end of the shaped steel beam flange plate, the formwork 16 of the shaped steel beam 2 is supported between the concrete columns, the steel beam steel supporting iron parts 14 are installed on the formwork 16, and the steel beam bottom reinforcement 17 is installed again, The formwork 16 below adopts some vertical rods 15, which are supported in two rows, and the vertical rod spacing in the row is guaranteed to be no more than 50 centimeters to meet the weight of the steel beam. (Add 6 vertical poles at the place where the steel beams support the iron parts, and support them in two rows to ensure the support of t...

Abstract

The invention relates to a building construction method, in particular to a non-steel-column type steel beam connection construction process, which solves the problem of the connection between a steel beam and a concrete structural column during the construction. The process comprises the following steps of: firstly, fabricating the steel beam and placing a template of the steel beam between concrete columns; secondly, hoisting the steel beam, putting the steel beam on the template, installing stirrups around a concrete column tendon above the steel beam, welding the stirrups with the tendon; thirdly, installing waist ribs, installing steel beam stirrups around the steel beam, installing beam penetrating steel bars which pass through the upper and lower web plates of the steel beam and are connected with the steel bars on the middle part of the concrete column through nut sleeves, installing stirrups around the concrete column steel bars on the side of the steel beam; fourthly, applying hooks onto the stirrups; and finally, erecting the template around the steel beam for pouring concrete. The construction process solves the problem of the connection between the reinforced concrete column and the steel beam without a steel column.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction technique for connecting steel beams without steel columns. Background technique [0002] In the current high-rise building construction, the existing column and steel beam connection mode is to weld the steel beam and the steel column in the column or connect with high-strength bolts, so that the steel beam and column are connected as a whole. However, when special design requirements are encountered, for example, the second floor of the main building is designed as a conversion floor, which is a frame-supported structure, and some of the beams are steel concrete structures, and the frame pillars are required to be reinforced concrete main, and no steel sections are designed inside the columns column. In this way, it is impossible to construct according to the existing technology, but this construction task must be completed, and the safety must also reach the ef...
