Abstract
The utility model discloses a cast-in-place concrete pre-built-in thin-wall box which is a closed box body composed of peripheral four sidewalls, a top face and a bottom face respectively arranged at the upper and the lower parts of the sidewalls, and one or more than one axial hollow tube communicated the top and the bottom surfaces is arranged in the thin-wall box. The utility model is characterized in that at least one of the mouth parts of both the upper and the lower ends of the hollow tube is provided with a large mouth towards the funnel-shaped mouth edge of the outer side of the thin-wall box. The utility model designs the end mouth part of the hollow tube of the thin-wall box into a funnel-shaped, concrete can easily enter from the upper mouth part of the hollow tube, or diffuses to the lower side of the bottom surface of the thin-wall box from the lower mouth part, and compared with the existing straight barrel hollow tube, the utility model is more favorable for the pouring of the concrete.
Description
Technical field
The utility model relates to construction engineering technical field, especially a kind of cast-in-situ concrete pre-buried type thin-walled box.
Background technology
Concrete filling thin-walled box is mainly used in the making of steel concrete hollow slab, the thin-walled box be by around four sidewalls and the upper and lower top of sidewall, the enclosed box body that the bottom surface constitutes.Also be provided with the axial hollow section that connects top, bottom surface in the existing thin-walled box, in construction, concrete can pour into the bottom of thin-walled box from the hollow section of thin-walled box, the bottom surface of thin-walled box is combined firmly with end steel mesh reinforcement, but the hollow section of existing thin-walled box is straight barrel structure, is unfavorable for the concrete bottom surface that pours into and enter the thin-walled box.
The utility model content
The purpose of this utility model is to provide a kind of cast-in-situ concrete pre-buried type thin-walled box, and concrete is poured in the hollow section of thin-walled box than more smoothly, and is convenient to concrete and spreads in the bottom surface of thin-walled box.
The technical solution of the utility model is: a kind of cast-in-situ concrete pre-buried type thin-walled box, be by around four sidewalls and the upper and lower top of sidewall, the enclosed box body that the bottom surface constitutes; also be provided with the axial hollow section of one or more perforation top, bottom surface in the thin-walled box, at least one in the oral area of described hollow section upper/lower terminal has the big mouthful of funnel mouth edge towards the thin-walled box outside.
The oral area of described hollow section upper/lower terminal all has the big mouthful of funnel mouth edge towards the thin-walled box outside.
The upper end oral area of described hollow section has the big mouthful of funnel mouth edge towards the thin-walled box outside.
The lower end oral area of described hollow section has the big mouthful of funnel mouth edge towards the thin-walled box outside.
Also be provided with one or more than one liner plates between the sidewall of described thin-walled box.
The utility model is designed to funnel-form with the port part of the hollow section of thin-walled box, and concrete can be smoothly entered from the upper oral part of hollow section, or is diffused into the below, bottom surface of thin-walled box from infraoral, and more existing straight tube hollow section is more conducive to concrete cast.

The specific embodiment
As shown in Figure 1, embodiment one of the present utility model has the hollow section 2 that connects top, bottom surface in the thin wall box 1, and the oral area of hollow section 2 upper/lower terminals all has the big mouthful of funnel mouth outside the thin-walled box along 3.
As shown in Figure 2, embodiment two of the present utility model is with the difference of embodiment one, and hollow section 2 only in the top oral area has the big mouthful of funnel mouth towards the thin-walled box outside along 3.
As shown in Figure 3, embodiment three of the present utility model is with the difference of embodiment one, and the oral area of hollow section 2 instrument in its lower end has the big mouthful of funnel mouth towards the thin-walled box outside along 3.
As shown in Figure 4, embodiment four of the present utility model, Fig. 4 removes the vertical view of end face for thin wall box 1, two liner plates 4 have also been added between the sidewall of box body, two hollow sections 2 are located between two liner plates 4, the oral area of hollow section 2 upper/lower terminals all has the big mouthful funnel mouth towards the thin-walled box outside along 3, has only demonstrated the suitable for reading of hollow section 2 among the figure, and it is identical among mouth structure and the embodiment one down.
Innovative point of the present utility model is the big mouthful of funnel mouth edge towards the thin-walled box outside of hollow section upper and lower end; distributing position or quantity as for the laying mode that only changes liner plate or quantity and hollow section; here enumerate no longer one by one; should all belong to the simple replacement of above embodiment, still in protection domain of the present utility model.
Claims (5)
1, a kind of cast-in-situ concrete pre-buried type thin-walled box, be by around four sidewalls and the upper and lower top of sidewall, the enclosed box body that the bottom surface constitutes; also be provided with the axial hollow section of one or more perforation top, bottom surface in the thin-walled box, it is characterized in that: at least one in the oral area of described hollow section upper/lower terminal has the big mouthful of funnel mouth edge towards the thin-walled box outside.
