Problems solved by technology

[0003] Since the comprehensive promotion of the policy of "no concrete and limited sticking" at the beginning of this century, blocks have been used to replace solid clay bricks in the filling walls of traditional concrete frame structures, which has achieved certain resource saving effects and reduced structural weight to a certain extent. , but because the infill wall is still a masonry structural component, its integrity is poor. In previous destructive earthquakes, the seismic damage of the infill wall, such as cross shear cracks, is still one of the typical earthquake damages. Although the ring beam structure is adopted The anti-seismic measures such as pillars, but did not fundamentally solve the occurrence of such earthquake damage
On the other hand, in order to prevent the infill wall from flashing and collapsing during the earthquake, the current codes stipulate that necessary connection measures must be taken between the masonry infill wall and the frame main structure, such as burying tie bars or laying reinforcement mesh etc. In this way, the stiffness contribution of the infill wall to the frame structure must be considered, which increases the seismic action. Some people propose to add horizontal and vertical flexible separation layers during the construction of the block wall, which can effectively reduce the impact of the block wall on the frame structure. The rigidity of the main body of the frame contributes, but the construction process is increased, the construction period is extended, and the quality of traditional masonry construction is difficult to be effectively guaranteed
It can be seen that as long as the traditional on-site masonry construction method is still used, there are two fundamental problems: the construction period is long, and the construction quality cannot be absolutely guaranteed, which leads to the fact that the impact of the filling wall on the seismic performance of the frame body cannot be fundamentally and effectively solved
[0006] Due to many reasons, the performance of prefabricated building structures cannot achieve the expected results, such as poor structural safety performance in previous earthquakes, too many on-site assembly nodes and too concentrated problems.

Embodiment Construction

[0038] The technical solutions and structures of the present invention will be described below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0039] The principles and benefits of the present invention are as follows Figure 1-Figure 11 As shown, the disclosed prefabricated integral frame structure residential system includes a cast-in-place column composite beam load-bearing frame, a split shock-absorbing prefabricated staircase, a prefabricated composite floor, and prefabricated infill interior and exterior wall panels. In the structural system, the mechanical performance requirements of "connection is completely connected, disconnection is completely disconnected" between components is fully considered, that is, beam-column joints are cast-in-place, part of primary and secondary beam joints are post-cast concrete, and prefabricated beam slabs are laid and post-cast The superimposed layers form a whole, the s...

Abstract

The invention provides an integrally assembled type frame structure housing system, and relates to the building technology of concrete structure industrialized residences. The system is characterized in that a load-bearing frame is formed by superposed beams and cast-in-place columns; separating damping type prefabricated stairs are adopted to serve as stairs of the system; floor slabs are prefabricated superposed floor systems; prefabricated infilled wall boards serve as infilled walls. Equivalent rigid joints are calculated for beam column joints through column cast-in-place, and hinged joints are calculated through the situation that grooves are preset in main beams through primary and secondary beam joints and then poured; calculation assumption of absolute rigidity in planes of the floor systems is achieved through prefabricated superimposition of beam slabs; a core clamped self-heat preservation hanging plate technology is adopted in an outer wall, a light batten with large holes serves as an inner wall, the grooves are reserved in the slabs and connected through steel dowel grouting, the inner infilled wall boards and the outreinfilled wall boards are flexibly connected with a body, and negative influences of the infilled walls on frame earthquake prevention can be effectively eliminated. The system can be well anti-seismic, is convenient and fast to construct, saves energy, protects environment and shortens the construction cycle.

Description

technical field [0001] The invention belongs to the technical field of construction of industrialized houses with concrete structures, and particularly relates to an assembled integral frame structure house system. Background technique [0002] The beam-slab-column components of traditional reinforced concrete frame structure houses are often poured concrete after the formwork is supported at the construction site. The connection between the components is reliable, the integrity and seismic performance are good, but the construction period is long and the management is complicated. [0003] Since the comprehensive promotion of the policy of "forbidding real and limiting sticking" at the beginning of this century, bricks have been used for filling walls in traditional concrete frame structures instead of solid clay bricks, which has achieved a certain effect of saving resources and reducing the weight of the structure to a certain extent. However, since the infill wall is sti...
