Abstract

A kind of precast floor slab reinforces the connection structure, comprises the first precast floor slab, the second precast floor slab, embedded bar, horizontal cracking resistance reinforcing bar, longitudinal cracking resistance reinforcing bar; The first described precast floor slab and the second precast floor slab are built-in reinforcing cage, outside fluid concrete structure; Embedded bar is installed on two pieces of assembled seam both sides of precast floor slab, and horizontal cracking resistance reinforcing steel bar laying in two pieces of precast floor slab upper surfaces, and is welded to connect with both sides embedded bar; Longitudinal cracking resistance reinforcing steel bar laying in horizontal cracking resistance reinforcing bar upper surface, and contacts with both sides embedded bar, and horizontal cracking resistance reinforcing bar, embedded bar and longitudinal cracking resistance reinforcing bar are fixedly connected by welding.Some embedded bars are layed in two pieces of assembled seam both sides of precast floor slab by the utility model, lay horizontal cracking resistance reinforcing bar and longitudinal cracking resistance reinforcing bar, and are welded and fixed with embedded bar, the overall stress-bearing capability of reinforced assembly formula building, reduce building damaged condition.

Description

A kind of precast floor slab reinforces the connection structure
Technical field
The utility model relates to floor link technique field, has been specifically related to a kind of precast floor slab and has reinforced the connection structure; Be mainly used in sectionalized house.
Background technology
Greatly develop along with socioeconomic, " energy-conservation and environmental protection " becomes the common target in the whole world and action, the development of low-carbon (LC) building, green building is in the ascendant, especially assembled architecture, its all components have been prefabricated in the factory, then be transported to job site to assemble, time and labour saving, have much incomparable advantage; But floor is after prefabricated completing, only carries out grouting cast at seam crossing and connect, when there is earthquake, this syndeton is easy to mutual dislocation, even collapses, and threatens safely to the people; Therefore the utility model provides a kind of precast floor slab and to reinforce the connection structure, some embedded bars are layed in two pieces of assembled seam both sides of precast floor slab, after precast floor slab on-site consolidation grouting cast, lay horizontal cracking resistance reinforcing bar and longitudinal cracking resistance reinforcing bar, and be welded and fixed with embedded bar, strengthen horizontal, the longitudinal stress at precast floor slab assembled seam place, the overall stress-bearing capability of reinforced assembly formula building, reduce building damaged condition, save maintenance fund, ensure people's safety, have good economic benefit and social benefit.
Utility model content
The utility model provides a kind of precast floor slab and to reinforce the connection structure, some embedded bars are layed in two pieces of assembled seam both sides of precast floor slab, after precast floor slab on-site consolidation grouting cast, lay horizontal cracking resistance reinforcing bar and longitudinal cracking resistance reinforcing bar, and be welded and fixed with embedded bar, strengthen horizontal, the longitudinal stress at precast floor slab assembled seam place, the overall stress-bearing capability of reinforced assembly formula building, reduce building damaged condition.
The utility model is achieved by the following technical solution: a kind of precast floor slab reinforces the connection structure, comprises the first precast floor slab, the second precast floor slab, embedded bar, horizontal cracking resistance reinforcing bar, longitudinal cracking resistance reinforcing bar; First precast floor slab and the second precast floor slab are built-in reinforcing cage, outside fluid concrete structure; Embedded bar is layed in two pieces of assembled seam both sides of precast floor slab, and embedded bar one end and the built-in reinforcing cage of precast floor slab are welded to connect, and the other end is arranged at distance precast floor slab upper surface 100mm place; Horizontal cracking resistance reinforcing steel bar laying in two pieces of precast floor slab upper surfaces, and is welded to connect with both sides embedded bar; Longitudinal cracking resistance reinforcing steel bar laying in horizontal cracking resistance reinforcing bar upper surface, and contacts with both sides embedded bar, and horizontal cracking resistance reinforcing bar, embedded bar and longitudinal cracking resistance reinforcing bar are fixedly connected by welding.
Described embedded bar is layed in the assembled seam both sides of precast floor slab, and the spacing distance of every two embedded bars is identical, and spacing distance depends on precast floor slab weight capacity.
The beneficial effects of the utility model are: by some embedded bars being layed in two pieces of assembled seam both sides of precast floor slab, after precast floor slab on-site consolidation grouting cast, lay horizontal cracking resistance reinforcing bar and longitudinal cracking resistance reinforcing bar, and be welded and fixed with embedded bar, strengthen horizontal, the longitudinal stress at precast floor slab assembled seam place, the overall stress-bearing capability of reinforced assembly formula building, reduce building damaged condition, save maintenance fund, ensure people's safety, have good economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is that a kind of precast floor slab reinforces the connection structure structural representation.
Fig. 2 is that a kind of precast floor slab reinforces the connection structure centre place enlarged drawing.
Reference numeral: 1 is the first precast floor slab, 2 is the second precast floor slab, and 3 is embedded bar, and 4 is horizontal cracking resistance reinforcing bar, and 5 is longitudinal cracking resistance reinforcing bar.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail.But embodiment of the present utility model is not limited to this.
As shown in Figure 1, a kind of precast floor slab reinforces the connection structure, comprises the first precast floor slab 1, second precast floor slab 2, embedded bar 3, horizontal cracking resistance reinforcing bar 4, longitudinal cracking resistance reinforcing bar 5; First all reinforcement components do antirust treatment, and the first precast floor slab 1 and the second precast floor slab 2 are built-in reinforcing cage, outside fluid concrete structure; Embedded bar 3 is layed in two pieces of assembled seam both sides of precast floor slab, and the spacing distance of every two embedded bars 3 is identical, and spacing distance depends on floor weight capacity; Embedded bar 3 one end and the built-in reinforcing cage of precast floor slab are welded to connect, and the other end is arranged at distance precast floor slab upper surface 100mm place, then carries out the cast of precast floor slab; After factory completes, be transported to job site and carry out the assembled of precast floor slab, assembled complete after, first carry out grouting cast at the assembled seam place of floor and be fixedly connected with, again horizontal cracking resistance reinforcing bar 4 is layed in two pieces of precast floor slab upper surfaces, and is welded to connect with both sides embedded bar 3; Then longitudinal cracking resistance reinforcing bar 5 is layed in horizontal cracking resistance reinforcing bar 4 upper surface, and is connected with both sides embedded bar 3, horizontal cracking resistance reinforcing bar 4, embedded bar 3 and longitudinal cracking resistance reinforcing bar 5 are fixedly connected by welding.As shown in Figure 2, complete reinforcing the connection of precast floor slab, strengthen horizontal, the longitudinal stress at precast floor slab assembled seam place, the overall stress-bearing capability of reinforced assembly formula building.
