Embodiment Construction

[0022] The following combination figure 1 with figure 2 , a preferred embodiment of the present invention is described in detail.

[0023] It should be noted that in this article, relational terms such as "first" and "second" are only used to distinguish one entity from another entity, and do not necessarily require or imply any such relationship between these entities. Actual relationship or sequence. It is to be understood that the terms so used are interchangeable under appropriate circumstances.

[0024] Such as figure 1 As shown, the overall hoisting method of the primary and secondary structures of the portal frame steel structure provided by the present invention includes the following steps:

[0025] S1. Complete the assembling of the portal frame steel structure with two adjacent column distances in the same span on the ground, as the overall hoisting unit of the roof; which includes in turn: assembling two steel beams 1, connecting and installing between the two...

Abstract

The invention relates to a gate-type steel frame steel structure primary-secondary structure overall hoisting method. The gate-type steel frame steel structure primary-secondary structure overall hoisting method comprises the steps that 1, every two adjacent gate-type steel frame steel structures in the same span are spliced on the ground to serve as a roof overall hoisting unit, specifically, according to the steps in sequence, two steel beams are spliced, a plurality of purlines are connected and mounted between the two steel beams, a plurality of inter-purline supports and a plurality of inter-purline oblique supports are connected and mounted between every two adjacent purlines, and the spliced roof overall hoisting unit forms a structure with the unchanged geometry and space stability; 2, the roof overall hoisting unit is suspended and mounted on the roof supporting structure; and 3, the step 1 and the step 2 are repeatedly executed till a gate-type steel frame steel structure workshop is completely hoisted. By adopting the method that the two adjacent steel beams are spliced on the ground to form the roof overall hoisting unit, the space stability is extremely good, the safety risk of construction can be effectively controlled, the mounting quality is improved, the construction speed is increased, and the mounting construction period of a main steel frame can be saved by50%.

Description

technical field [0001] The present invention relates to a method for overall hoisting of the primary and secondary structures of a portal frame steel structure, and specifically refers to a method for integral hoisting of the primary and secondary roof structures of a portal frame steel structure factory building during installation and construction, which belongs to the field of building energy-saving construction technology field. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. Steel has the characteristics of good toughness, good plasticity, uniform material, high structural reliability, and good heat resistance. When the temperature is below 150 ℃, the change of steel properties is small. In addition, the demolition of steel structure buildings will hardly generate construction waste, and all materials can be recycled and reused. Therefore, steel structures have been widely...
