Problems solved by technology

However, there are still the following disadvantages in its application to steel structure houses: (1) It is necessary to set up a full house of scaffolding on site, set up formwork to tie steel bars, and pour concrete. The workload on site is large, which cannot meet the needs of rapid assembly of steel structure buildings.
(2) It is difficult to connect with the steel column, and it is difficult to connect the steel bar with negative bending moment to the steel column
(3) The earthquake resistance is poor, and the applicable height in the earthquake zone is greatly restricted
(4) The punching resistance is weak, and column caps are usually installed, which affects the utilization of indoor space
The above problems make it difficult to apply it to steel structure houses.

Embodiment Construction

[0032] The present invention will be described more fully below using examples. This invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein.

[0033] For ease of description, spatially relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature relative to another element or feature shown in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientatio...

Abstract

The invention discloses an assembly type steel structure overlapped hollow floor which comprises steel beams, prefabricated bottom slabs, ribbed beams, filling bodies and cast-in-place concrete layers. The section of each steel beam is in an H shape. Each steel beam is composed of an upper flange, a web and a lower flange, and the lower flange is wider than the upper flange. The assembly type steel structure overlapped hollow floor is good in anti-seismic performance, through the arrangement of a shear connection structure, cooperative work of the steel beams and the hollow floor can be guaranteed, due to the restriction of longitudinal ribs and hoopings in the solid areas where the steel beams intersect with the hollow floor, the effect similar to steel reinforced concrete hidden beams is achieved, and the anti-seismic performance is good.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an assembled steel structure laminated hollow floor and a construction method thereof. Background technique [0002] In steel structure buildings, the floor structure mostly adopts cast-in-place concrete floor slabs, reinforced truss floor slabs, and profiled steel plate composite floor slabs. The floor slab rests on the upper flange of the steel beam. Morph so the two can work together. The above-mentioned floor forms have been widely used in steel structure buildings due to their good economy and simple construction. However, the size of the steel beams is relatively large, and when used in residential buildings, the position of the steel beams will protrude from the interior, which will affect the viewing and use of the interior. In addition, the floor span is limited, resulting in a dense column network, which makes it difficult to make full use of the light...
