Abstract

The utility model discloses a mould for producing cast-in-place concrete pre-buried thin wall box. The mould is composed of a bottom mould plate and four side mould plates, wherein the four side mould plates hinged with the circumambient side edges of the bottom mould plate and can be turned from horizontality to verticality; the shape of the bottom mould plate is approximatively matched with the shape of the bottom surface of a thin wall box, and the shape of each of the four side mould plates is approximatively matched with the shape of each of the four side walls of the thin wall box. When the side mould plates and the bottom mould plate are horizontally placed, the mould designed by the utility model can make the material of a box body be uniformly daubed on the bottom mould plate and the four side mould plates, the material of a box body can not be accumulated towards one side because of the effect of gravity, the side walls and the bottom surface of a molded box body are smooth and uniform, and the side mould plates are turned to verticality; after the material of the box body on each of the mould plates is firmly bound, and after the four side mould plates are separated with the material of the box body, the four side mould plates are turned to horizontality, and a produced thin wall box with an upper opening can be extracted from a bottom plate; then, the top surface of the thin wall box is stuck and the manufacture is completed.

Description

Make the mould of cast-in-place concrete built-in type thin-walled box

Technical field

The utility model relates to construction engineering technical field, especially a kind of mould of making cast-in-place concrete built-in type thin-walled box.

Background technology

Cast-in-place concrete built-in type thin-walled box is mainly used in the making of armored 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.The making of existing thin-walled box; be to produce former or formpiston in advance; adopt demoulding method to produce bottom surface and the opening box that sidewall constituted all around earlier; and then end face is bonded on the opening of opening box and forms enclosed box body; adopting former demoulding method is to coat the cell material demoulding then at the concave surface of former, and adopting formpiston demoulding method is to coat the cell material demoulding then in the convex surface of former.Cell material generally is solid, the pulp mixture that are constituted by filler, cement, resin glue; because mould is the structure of concave or convex; the molding plane of four sidewalls has just formed high low head naturally; institute's cell material of smearing can sink owing to self gravitation on former or the formpiston; thereby cause the box wall thickness inhomogeneous, even can produce defectives such as aperture, crack, also will adopt the way of striking off, filling up to remedy defective on the box body after the demoulding; therefore operating efficiency is lower, and defect rate is higher.

The utility model content

The purpose of this utility model is to provide a kind of mould of easy to operate cast-in-place concrete built-in type thin-walled box, can produce the uniform thin-walled box of box wall thickness.

The technical solution of the utility model is: a kind of mould of making concrete filling thin-walled box, described mould by end template and with end template around hinged can the constituting of side from four side templates that level is turned to vertical state, the bottom shape of the shape of end template and thin-walled box is approximate to be cooperated, and the shape of four side templates then cooperates with the shape approximation of four sidewalls of thin-walled box.

Described four side templates are hinged by hinge and end template.

The mould that the utility model is designed, because four side templates can be turned to vertical state from level, during therefore with side template and end template horizontal positioned, cell material can be spread upon uniformly on end template and four side templates, because end template and side template are horizontal positioned, so cell material can not piled up to a side because of gravity effect, make box side wall and bottom surface after the moulding smooth evenly, behind the sidewall and bottom surface moulding of box body, side template is turned to vertical state, box side wall on the side template dock mutually and with end template on box bottom to being connected into the opening box body, and use binding to be bonded together, when the cell material on each template bonding firmly after, four side templates are separated the back and are turned to level with cell material, the upper shed thin-walled box of making can be taken out from base plate, and then the end face that is stained with the thin-walled box is finished making.

Description of drawings

Fig. 1 is a mould deployed configuration schematic diagram of the present utility model;

Fig. 2 is the structural representation behind the die assembly of the present utility model;

The specific embodiment

As shown in Figure 1, the mould that the utility model is designed, all be hinged with four side templates 2 on each side around the end template 1 of rectangle by hinge 3, the shape of end template 1 cooperates with the bottom shape of thin-walled box is approximate, the shape of four side templates 2 then cooperates with the shape approximation of four sidewalls of thin-walled box, four side templates 2 can be turned to vertical state from level by the hinge 3 that connects separately, are combined into box shape as shown in Figure 2.

When making the thin-walled box, earlier cell material 4 is spread upon end template 1 and four side templates 2, but because end template 1 and four side template 2 equal horizontal positioned, can guarantee that cell material 4 can thickness spreads upon the surface of template uniformly, after cell material 4 fixed moulding, four side templates 2 and cell material 4 are turned to vertical state and are docking together mutually, and use and to carry out the joint of cell material 4 bonding with binding, when the cell material on each template 4 bonding firmly after, four side templates 2 are separated the back and are turned to level with cell material 4, the upper shed thin-walled box made can be taken out, and then the end face that is stained with the thin-walled box is finished making.

Claims

1, a kind of mould of making cast-in-place concrete built-in type thin-walled box, it is characterized in that: described mould by end template and with end template around hinged can the constituting of side from four side templates that level is turned to vertical state, the bottom shape of the shape of end template and thin-walled box is approximate to be cooperated, and the shape of four side templates then cooperates with the shape approximation of four sidewalls of thin-walled box.

2, mould according to claim 1 is characterized in that: described four side templates are hinged by hinge and end template.
