Abstract
The utility model discloses a superimposed concrete slab joint seam structure, and belongs to the field of building structures. According to the design, the superimposed concrete slab joint seam structure is composed of superimposed concrete slab prefabricated bottom plates, angle iron connecting pieces and cast-in-place concrete. Symmetrical bevel edges are arranged on the two longitudinal sides of the superimposed concrete slab prefabricated bottom plates. The angle iron connecting pieces are evenly embedded in the bevel edges on the two sides of the superimposed concrete slab prefabricated bottom plates at intervals. The exposed ends of the embedded angle iron connecting pieces of the bevel edges of every two adjacent superimposed concrete slab prefabricated bottom plates are fastened and connected correspondingly through bolts, and slope-shaped grooves are formed between the exposed ends. Concrete is poured along the surfaces of the spliced superimposed concrete slab prefabricated bottom plates and the slope-shaped grooves between the spliced superimposed concrete slab prefabricated bottom plates to form superimposed concrete slab joint seams which are integrally connected with superimposed concrete slab surface plates. The superimposed concrete slab joint seam structure is simple in structure, symmetrical in structure and easy, convenient and rapid to manufacture and construct, and cracks can be effectively prevented from appearing in joints due to the fact that the thicknesses of cast-in-place concrete layers of the joints are increased through the design of the longitudinal bevel edges of the prefabricated layers.
Description
Technical field
A kind of concrete folding plate splicing seams structure of the utility model, belongs to building structure field.
Background technology
Concrete folding plate splicing seams reinforcement frame or the assembling reinforcement cages made separately of adopting at present more, be arranged between adjacent concrete superimposed sheet, then it is carried out to concreting, although the initial stage structure after construction is very firm, because preformed layer is different from in-situ layer setting time, therefore, it is still stratiform, in conjunction with insecure, As time goes on or for a long time use, even there will be the phenomenons such as crack in the stitching portion of preformed layer and in-situ layer.Therefore, extremely pay close attention in the industry superimposed sheet splicing seams place and produce crack problem and solution thereof.
Utility model content
The purpose of this utility model is to provide a kind of concrete folding plate splicing seams structure, with simple structural reinforcing seam crossing bond strength, thereby effectively prevents that crack from appearring in junction, improves whole building performance.
The utility model patent is achieved by the following scheme:
A kind of concrete folding plate splicing seams structure of the utility model, by concrete folding plate prefabricated panel, angle iron connecting piece and cast-in-situ concrete composition, there is symmetrical groove limit the longitudinal both sides of described concrete folding plate prefabricated panel, and the even interval of described angle iron connecting piece is embedded in groove limit, concrete folding plate prefabricated panel both sides; The pre-buried angle iron connecting piece exposed junction on adjacent two block concrete superimposed sheet prefabricated panel groove limits, be fastenedly connected by bolt correspondence respectively, and form betwixt domatic groove, along the surface of the concrete folding plate prefabricated panel having spliced and domatic groove concreting therebetween, form the concrete folding plate splicing seams being connected with concrete folding plate panel one.
Described concrete folding plate is made up of concrete folding plate prefabricated panel and concrete folding plate panel.
A kind of concrete folding plate splicing seams structure of the utility model, simple in structure, be arranged symmetrically with, manufacture and easy construction are quick, and the design of the longitudinal groove of preformed layer limit has increased stitching portion cast-in-situ concrete layer thickness, in conjunction with firmly, can effectively prevent that crack from appearring in stitching portion.
Accompanying drawing explanation
Fig. 1 the utility model concrete folding plate prefabricated panel groove limit and pre-buried angle iron connecting piece schematic diagram;
The adjacent two block concrete superimposed sheet prefabricated panels of Fig. 2 the utility model are by angle splice joint schematic diagram;
The adjacent two block concrete superimposed sheet splicing seams structure section schematic diagrames of Fig. 3 the utility model.
The specific embodiment
How a kind of concrete folding plate splicing seams structure of existing accompanying drawings the utility model is implemented:
A kind of concrete folding plate splicing seams structure of the utility model, by concrete folding plate prefabricated panel 4, angle iron connecting piece 1 and cast-in-situ concrete composition, there is symmetrical groove limit 5 the longitudinal both sides of described concrete folding plate prefabricated panel 4, evenly be arranged at intervals with pre-buried angle iron connecting piece 1 along groove limit, concrete folding plate prefabricated panel both sides 5, the vertical end of this pre-buried angle iron connecting piece 1 is exposed outside, and sees Fig. 1; The pre-buried angle iron connecting piece 1 on the groove limit of adjacent two block concrete superimposed sheet prefabricated panels 4, be fastenedly connected by bolt 2 correspondences respectively, and form betwixt domatic groove C, see Fig. 2, along the surface of the adjacent two block concrete superimposed sheet prefabricated panels 4 that spliced and domatic groove C concreting therebetween, form the concrete folding plate splicing seams 3 being connected with concrete folding plate panel 3-1 one, see Fig. 3.
Described concrete folding plate is made up of concrete folding plate prefabricated panel 4 and concrete folding plate panel 3-1.
Claims (2)
1. a concrete folding plate splicing seams structure, it is characterized in that, by concrete folding plate prefabricated panel, angle iron connecting piece and cast-in-situ concrete composition, there is symmetrical groove limit the longitudinal both sides of described concrete folding plate prefabricated panel, and the even interval of described angle iron connecting piece is embedded in groove limit, concrete folding plate prefabricated panel both sides; The pre-buried angle iron connecting piece exposed junction on adjacent two block concrete superimposed sheet prefabricated panel groove limits, be fastenedly connected by bolt correspondence respectively, and form betwixt domatic groove, along the surface of the concrete folding plate prefabricated panel having spliced and domatic groove concreting therebetween, form the concrete folding plate splicing seams being connected with concrete folding plate panel one.
