Problems solved by technology

[0006] (2) Secondly, from the perspective of structural performance, it is difficult to guarantee the design of strong joints and weak members after pouring joints
[0007] (3) Finally, in terms of construction technology, the operation of pouring concrete into the joint formwork is complicated, and the joint solidification process requires special support, which is labor-intensive and time-consuming
[0008] Moreover, under wet connection, the splicing structure is disposable, and the splicing components cannot be reused

Embodiment 1

[0039] Such as Figure 1-8 As shown, a detachable prefabricated frame structure based on section steel connection of the present invention includes the following three parts: prefabricated beam 100 , buckle, and prefabricated column 300 .

[0040] The prefabricated beam 100 will be introduced first. Such as figure 2 As shown, the prefabricated beam 100 includes a prefabricated beam body, a beam I-beam 1 embedded in the left and right ends of the prefabricated beam body, and a beam reinforcement cage welded together with the beam I-beam 1 at the left and right ends (in the figure not shown), and the concrete beam body 2 of the embedded beam reinforcement cage and part of the I-shaped steel 1 at the left and right ends. The above structure endows the foundation of prefabricated beams with a reinforced concrete structure, guaranteeing its basic connection properties and strength.

[0041] Further, the beam I-beam 1 is connected to the upper and lower longitudinal ribs inside ...

Embodiment 2

[0056] A kind of detachable prefabricated frame structure based on section steel connection formed based on the optimal technical scheme of embodiment 1, its assembly method is as follows:

[0057] S1, the connection between the prefabricated column and the prefabricated beam. During installation, the beam I-beam at one end of the prefabricated beam is docked with the I-beam of the same specification column exposed at the steel column-beam joint of the prefabricated column-beam-column, and connected through the cover plate and bolts Recycling can be achieved by removing the bolts during later disassembly;

[0058] S2. After connecting two different prefabricated columns up and down, install the flat head buckle and the oblique head buckle. Fixed position, when disassembling, first remove the spot welding connection, remove the flat head buckle and the oblique head buckle to realize the disassembly.

[0059] The above embodiments illustrate that the present invention is strong...

Abstract

The invention provides a detachable frame structure based on sectional steel connection and a fabricating method thereof. The detachable frame structure structurally comprises prefabricated columns, prefabricated beams and buckles, wherein detaching points of the prefabricated columns are arranged near points of inflection of the columns, and the prefabricated columns are connected through mutualnesting of inner rings at the two ends of the prefabricated columns and inner barrels as well as mutual butt-joint of outer rings and outer barrels and fixing through the buckles; each buckle comprises a flat-headed buckle body and an inclined-headed buckle body; steel column-beam joints formed by welding square steel tubes and column I-shaped steel are arranged at beam-column joint portions of the prefabricated columns, and the prefabricated columns and the prefabricated beams are butt-jointed through a method that the column I-shaped steel on the steel column-beam joints and beam I-shaped steel at one end of each prefabricated beam are connected and then fixed through cover plates and bolts. The invention further provides a fabricating method based on the frame structure. A dry-connection mode is adopted, using can be achieved immediately after connection, the connecting quality is reliable and easy to detect, detaching is achieved through the structural form, the construction mode is concise, and the standards of higher speed, more reliability and more saving can be achieved.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a detachable prefabricated frame structure based on section steel connection and an assembly method thereof. Background technique [0002] Prefabricated structures (hereinafter referred to as: prefabricated structures) are widely used all over the world, and prefabricated structures can realize the industrialized production of buildings. In the case of declining demographic dividend and high cost of on-site construction personnel, the development of prefabricated structures may be a new direction of building construction. At the same time, the prefabricated structure is energy-saving and environmentally friendly, and can greatly reduce the adverse effects of on-site construction. Under high environmental protection requirements, the cast-in-place operation on the construction site will be impacted. The use of fully prefabricated structures can well overcome on-site...
