The utility model provides a set of precast concrete culvert that butt joint stability is good for the personnel, set up protruding mouth and the notch of pegging graft each other respectively to culvert both ends, when playing the direction effect, can improve the intensity of culvert butt joint, set up the hoisting machine who supplies hoisting equipment to tie the knot in a flexible way and connect, make the convenience of later stage handling construction better, it is comparatively smooth to solve current precast concrete box culvert because of the butt joint face, do not can help the butt joint grafting structure between the box culvert, lead to the box culvert easily to be moved by the crust of the earth and produce the problem of dislocation of sinking in later stage use.
Description
Technical Field
The utility model relates to the technical field of concrete prefabricated parts, in particular to a concrete prefabricated part.
Background
The concrete prefabricated culvert box for road and bridge construction is very popular, and standardized production is adopted, so that the site construction time and labor cost can be greatly reduced, and the environment protection is facilitated.
The prefabricated culvert of current concrete is in the concatenation use period, because of being the plane to the interface between the adjacent culvert, leads to the direct unable direction grafting of accomplishing of culvert, influences the connectivity of integration after the culvert concatenation.
The concrete prefabricated member based on the existing culvert box has the following defects: the existing concrete precast box culvert has the problems that the box culvert is easy to sink and misplace due to the fact that the butt joint surface is smooth and the butt joint splicing structure between the box culvert is not facilitated, and the box culvert is easy to be moved by the crust in the later use. To this end we propose a concrete preform.
Disclosure of Invention
The utility model mainly aims to provide a concrete prefabricated member, which can effectively solve the problems in the background technology.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a concrete prefab, includes prefabricated culvert, grafting tang and grafting notch, still includes connecting hole, connecting rod and rings, prefabricated culvert one end is provided with the grafting tang with it an organic whole, prefabricated culvert other end is provided with the grafting notch with it an organic whole, through grafting tang and grafting notch grafting connection between the prefabricated culvert.
Further, the corners of the grafting convex opening and the grafting concave opening are respectively provided with a connecting hole, and the connecting rods are sequentially inserted into the connecting holes of the adjacent butt-joint prefabricated culvert boxes.
Further, hanging rings are arranged on two sides of the top of the prefabricated culvert box, and embedded rings integrated with the hanging rings are bent on the hanging rings.
Further, the length, width and height of the inner cavity of the inserting concave opening are consistent with the length, width and height of the inserting convex opening.
Compared with the prior art, the utility model has the following beneficial effects: through prefabricated culvert, grafting tang, grafting notch, connecting hole, connecting rod and rings component, realize providing the prefabricated culvert of concrete that a set of butt joint stability is good for the personnel, set up tang and notch of pegging graft each other respectively to culvert both ends, when playing the direction effect, can improve the intensity of culvert butt joint, set up the hoisting mechanism that can supply hoisting equipment nimble tie to connect, make the convenience of later stage handling construction better, it is comparatively smooth because of the butt joint face to solve current prefabricated box culvert, do not have to help the butt joint grafting structure between the box culvert, lead to the box culvert easily to be by the problem of the dislocation of sinking of crust motion in later stage use.

Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
As shown in fig. 1-4, a concrete prefabricated member comprises a prefabricated culvert box 1, an inserting convex opening 2, an inserting concave opening 3, a connecting hole 4, a connecting hole 5 and a hanging ring 6, wherein one end of the prefabricated culvert box 1 is provided with the inserting convex opening 2 integrated with the prefabricated culvert box, the other end of the prefabricated culvert box 1 is provided with the inserting concave opening 3 integrated with the prefabricated culvert box, and the prefabricated culvert boxes 1 are connected with the inserting concave opening 3 in an inserting mode through the inserting convex opening 2.
The connecting holes 4 are respectively formed in the corners of the inserting convex openings 2 and the inserting concave openings 3, and the connecting rods 5 are sequentially inserted into the connecting holes 4 of the adjacent butt-joint prefabricated culvert boxes 1.
The two sides of the top of the prefabricated culvert box 1 are provided with hanging rings 6, and the hanging rings 6 are bent to form an embedded ring 7 integrated with the hanging rings 6.
The length, width and height of the inner cavity of the inserting concave opening 3 are consistent with those of the inserting convex opening 2.
It should be noted that, the utility model is a concrete prefabricated member, when in operation, constructors pour concrete materials into the corresponding mould of the prefabricated culvert 1, and insert the embedded ring 7 at the bottom of the hanging ring 6 into the concrete for embedding, after the concrete is solidified, the mould is opened, the prefabricated culvert 1 can be obtained, constructors prepare the prefabricated culvert 1 with required number, and tie the hanging ring 6 by the hoisting equipment, the prefabricated culvert 1 can be hoisted to the road section of the required construction, based on the arrangement of the splicing convex opening 2 and the splicing concave opening 3, the adjacent prefabricated culvert 1 is spliced, the prefabricated culvert 1 is spliced, then the connecting rod 5 is sequentially inserted and connected with the connecting hole 4 of the prefabricated culvert 1, so as to further ensure the connection integrity between the prefabricated culvert 1, and when the earth crust movement occurs in the later stage, the larger dislocation phenomenon between the prefabricated culvert 1 can not occur, and the stability of the use between the prefabricated culvert 1 of the concrete is greatly ensured.
