Abstract
The invention discloses a cast-in-place floor joint splicing structure for a travelling crane, comprising an expansion joint (5) at the spliced part of a floor, wherein a leveling layer (3) is arranged above the floor, a distance L is remained between the edge of the leveling layer (3) and the edge of the expansion joint (5), plastic foam (1) is inlaid in the expansion joint (5), a reinforcement mat (2) is arranged at the upper end of the expansion joint (5) in a spanning manner, and compensating concrete (4) with an archy upper end is cast on the reinforcement mat (2). Compared with the prior art, the floor joint achieves simple and easily implemented structure, low cost, high strength, hard floor damage and stable crane travelling, and meets the requirement of a potroom on insulation.
Description
Technical field
The present invention relates to a kind of piece structure of floor, particularly a kind of piece structure of crossing the car cast-in-situ floor.
Background technology
In industrial construction; The situation that the mule carriage right and wrong are usually seen on the inner concrete platform of factory building, and concrete frame generally will be provided with the shrinkage joint when surpassing 55m according to standard; As shown in Figure 1; Car frequently rolls impact to the floor place of cracking in the process of walking back and forth, seam two ends floor is destroyed by driving easily.So the piece structure here haves much room for improvement.
Summary of the invention
Technical problem to be solved by this invention is, a kind of car cast-in-situ floor piece structure of crossing is provided, and makes driving steadily, and can not destroy floor.
Technical scheme of the present invention: in order to solve the problems of the technologies described above; The car cast-in-situ floor piece structure of crossing of the present invention comprises the shrinkage joint of floor jointing positions, and the top of floor is a leveling layer; Leave a distance L between the edge of leveling layer and the edge at shrinkage joint; Be embedded with plastic foam at the shrinkage joint, cross in the upper end at shrinkage joint and be placed with steel mesh reinforcement, be cast with the compensating concrete of upper end band arch on the steel mesh reinforcement.
The edge bottom of leveling layer is stretched in the both sides of steel mesh reinforcement.
The steel mesh reinforcement below is stretched in the lower end of compensating concrete, connects plastic foam.
The cross section, edge of leveling layer is an arc.
Compared with prior art, floor piece of the present invention easy realization simple in structure, cost is low, and intensity is high, and floor is survivable, and train stability satisfies the insulating requirements of potroom, remarkable in economical benefits again.
Description of drawings
Fig. 1 is intrinsic structural representation;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Embodiments of the invention 1: as shown in Figure 2, the car cast-in-situ floor piece structure of crossing of the present invention comprises the shrinkage joint 5 of floor jointing positions, and the width at shrinkage joint 5 is a.The top of floor is a leveling layer 3, and the thickness of leveling layer 3 is h0, and the cross section at the edge of leveling layer 3 is an arc, and leaves a distance L between the edge at shrinkage joint 5, and 5 are embedded with plastic foam 1 at the shrinkage joint, and the distance at top of 5 far from the shrinkage joint, the upper end of plastic foam 1 is h.
5 upper ends has steel mesh reinforcement 2 at the shrinkage joint, and steel mesh reinforcement 2 is crossed at the shrinkage joint 5 upper end, and both sides stretch into the edge bottom of leveling layer 3, promptly stretches into curved bottom.Also be cast with the compensating concrete 4 of upper end band arch on the steel mesh reinforcement 2, interplanar vertical distance is h1 on the arch top of compensating concrete 4 and the leveling layer 3, and steel mesh reinforcement 2 belows are stretched in the lower end of compensating concrete 4, connects plastic foam 1.
Wherein, h1=h=a, L=h0.
During construction, treat that floor slab structure layer construction accomplished after, 5 are embedded in plastic foam 1 at the shrinkage joint; Above shrinkage joint 5, place steel mesh reinforcement 2 then, pour into a mould leveling layer 3 again, reserve distance L during cast; After treating that leveling layer 3 intensity reach requirement; The compensating concrete 4 of cast top band arch above steel mesh reinforcement 2, the below of this compensating concrete 4 sees through steel mesh reinforcement 2, arrives plastic foam 1.
Claims (4)
1. cross car cast-in-situ floor piece structure for one kind; The shrinkage joint (5) that comprises the floor jointing positions; The top of floor is leveling layer (3), it is characterized in that: leave a distance L between the edge of the edge of leveling layer (3) and shrinkage joint (5), (5) are embedded with plastic foam (1) at the shrinkage joint; The upper end of (5) is crossed over and is placed with steel mesh reinforcement (2) at the shrinkage joint, is cast with the compensating concrete (4) of upper end band arch on the steel mesh reinforcement (2).
2. the car cast-in-situ floor piece structure of crossing according to claim 1, it is characterized in that: the edge bottom of leveling layer (3) is stretched in the both sides of steel mesh reinforcement (2).
3. the car cast-in-situ floor piece structure of crossing according to claim 1, it is characterized in that: steel mesh reinforcement (2) below is stretched in the lower end of compensating concrete (4), connects plastic foam (1).
4. the car cast-in-situ floor piece structure of crossing according to claim 1, it is characterized in that: the cross section, edge of leveling layer (3) is an arc.
