The utility model discloses reinforced structure includes a plurality of strength steel units, and strength steel unit parallel arranges between the original reinforcing bar of floor, and the both ends of strength steel unit link to each other with shear force wall or roof beam. The utility model discloses the settlement zone at existing building reinforced concrete floor consolidates the processing, adopts the reinforced structure of powerful steel high-strength concrete, and the original structure of make full use of floor, the atress is reasonable, does not increase original floor thickness, does not influence original space.
Description
Technical Field
The utility model belongs to the floor field of consolidating, concretely relates to reinforced structure of large-span floor.
Background
In recent years, with the improvement of economic living standard of people, the space of a living room or a public area in a newly built house is continuously enlarged, a large number of large-span floor slabs are generated, but the large-span floor slabs have the problems of insufficient bearing capacity, cracking, overlarge deflection and the like due to the design, construction quality and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a reinforced structure of large-span floor to solve the large-span floor and appear that the bearing capacity is not enough, fracture and the too big scheduling problem of amount of deflection.
The technical scheme of the utility model is that: the utility model provides a reinforced structure of large-span floor, includes a plurality of strength steel units, and strength steel unit parallel arrangement is between the original reinforcing bar of floor, and the both ends of strength steel unit link to each other with shear force wall or roof beam.
As a further improvement of the utility model, the strength steel unit is formed by connecting a plurality of strength steel sections in sequence.
As a further improvement, the steel connecting plate is connected between the adjacent steel sections and fixed on the steel sections through the connecting bolts.
As the utility model discloses a further improvement, strength steel unit passes through the tip steel sheet and is connected with shear force wall or roof beam, and the buried plate welding of tip steel sheet lateral part and shear force wall or roof beam, tip steel sheet pass through high strength bolt to be fixed on strength steel unit.
The beneficial effects of the utility model are that: the utility model discloses the settlement zone at existing building reinforced concrete floor consolidates the processing, adopts the reinforced structure of powerful steel high-strength concrete, and the original structure of make full use of floor, the atress is reasonable, does not increase original floor thickness, does not influence original space. The utility model discloses implement portably, material saving provides an environment-friendly reinforcement method.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 4, a reinforcing structure of a large-span floor slab includes a plurality of steel units 1, the steel units 1 are arranged in parallel between original steel bars 2 of a floor slab 3, and both ends of the steel units 1 are connected to a shear wall or a beam 5.
The steel unit 1 is formed by connecting a plurality of steel sections 4 in sequence. Adjacent steel sections 4 are connected through connecting steel plates 6, and the connecting steel plates 6 are fixed on the steel sections 4 through connecting bolts 7.
The steel section 4 is made of I-shaped steel.
The strength steel unit 1 is connected with the shear wall or beam 5 through the end steel plate 8, the side part of the end steel plate 8 is welded with the buried plate 9 of the shear wall or beam 5, and the end steel plate 8 is fixed on the strength steel unit 1 through the high-strength bolt 10.
A method for reinforcing a large-span floor slab comprises the following specific steps:
firstly, unloading the load of a floor slab 3, reliably supporting the bottom of the floor slab 3, and performing inverted arch support at the bottom of a settlement area of the floor slab 3;
chiseling concrete in a settlement area of the floor slab 3, and reserving the original steel bars 2 of the floor slab 3;
thirdly, sequentially penetrating the steel sections 4 through the original steel bars 2 of the floor slab 3 and supporting the steel bars 2, connecting the adjacent steel sections 4 to form steel units 1, arranging a plurality of steel units 1 in parallel in the settlement area of the floor slab 3, and connecting two ends of each steel unit 1 with a shear wall or beam 5 to form a whole span support;
and step four, pouring high-strength concrete (larger than C45) in the chiseled area, pouring low-strength concrete at the joint of the high-strength concrete and the original floor slab 3, and tamping to prevent the low-strength concrete from flowing into the high-strength concrete pouring part.
The utility model discloses not increasing original floor thickness, not influencing under the prerequisite in original space, the settlement zone to existing building reinforced concrete floor 3 consolidates the processing, the original structure of make full use of floor 3, chiseling off floor 3's settlement zone's concrete after, utilize a plurality of strength steel unit 1 to support between floor 3 original reinforcing bar 2, then removing regional high strength concrete grade concrete pouring with chiseling, resume floor 3's original appearance, do not increase floor 3 thickness, occupation space not. The end part of the steel unit 1 is connected with the shear wall or beam 5, and the bearing of the floor slab 3 is not increased. The steel unit 1 is formed by connecting a plurality of steel sections 4, so that construction is facilitated.
