Description

Improved generation is built-in fitting for building

Technical Field

The utility model belongs to the building field, specificly relate to an improved generation built-in fitting for building.

Background

In the field of buildings, particularly high-rise buildings, the building of external frames is a prerequisite for other constructions. However, considering the strength of the steel pipe of the built external frame, when the floor reaches a certain height, the structure of the cantilever frame is adopted, namely, when concrete is poured on the low floor, I-shaped steel is embedded through the wall in advance and extends out of the building by a certain length, and the outward extending parts are used as bearing points of the external frame of the higher floor. The embedding direction, the extending length and the like of the I-shaped steel are arranged according to specific design. Because of the large load-bearing capacity of the i-beams, for safety reasons, it is common to fix and reinforce indoor parts, for example, floor surfaces and floor beams by u-shaped embedded part anchoring. When the construction is finished, all the exposed parts of the I-beams indoors and outdoors are required to be cut, damaged parts of the building body are required to be repaired, and the I-beams embedded in the concrete are continuously reserved. The traditional mode is labor-consuming and material-consuming and is not suitable.

Various technical improvement attempts are made in the industry, and at present, a special embedded part is successfully adopted, and is embedded into a mold in advance before concrete pouring, and a fixing position of I-shaped steel is reserved. Thus, the I-steel can be detached and recycled, and the damage of the embedded part to the floor is much smaller than that of the traditional structure, for example, the patent application with the publication number of CN 204098470U. However, in practical use, the scheme also has many problems, for example, the diameter of the temporary fixing screw is small, but the reserved through hole is too large, the temporary fixing screw is only fixed by the screw thread in the plastic protective cover, because the concrete is quickly and largely toppled downwards on the construction site, the embedded part is easy to deviate from the position and even be damaged by punching, and the length of the embedded part in the design is fixed, so when the length of the embedded part needs to be lengthened on the construction site, the scheme in the patent is not applicable.

Preferably, the embedded pipe (1) further comprises a first limiting disc (11), the reducing plug (2) further comprises a second limiting disc (22), the first limiting disc (11) and the second limiting disc (22) are both recessed inwards, and the second limiting disc (22) is contained in a recessed cavity formed by the first limiting disc (11) in an assembly state.

The utility model provides a under the technical scheme condition, construction side not only can increase a clamping screw's impetus when using, still because the inside sunken design of first spacing dish and the spacing dish of second for the built-in fitting of this scheme is better for the sealed effect of template, is more difficult for letting the concrete liquid infiltration built-in fitting influence later stage use. Furthermore, due to the fact that the fixing piece 3 is designed, the application range of the embedded part is expanded better, and the depth of the embedded part can be modified on site by a construction party.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

The concrete scheme, as shown in fig. 1, the utility model discloses the built-in fitting that technical scheme mentioned includes: the pipe joint comprises a pre-buried pipe 1, a reducing plug 2 and a fixing piece 3.

As shown in the figure, a plurality of supporting pieces 21 are arranged on the columnar part of the reducing plug 2 along the radial direction, all the supporting pieces 21 are tangent to the inner diameter pipe wall of the embedded pipe 1 at the corresponding position, and the reducing plug 2 is clamped at one end of the embedded pipe 1.

The other end of the embedded pipe 1 is provided with an internal thread, the fixing piece 3 is provided with a matched external thread, and the fixing piece 3 is in threaded connection with the embedded pipe 1.

Particularly, the utility model discloses reducing stopper 2 that mentions in the scheme still is provided with interior through-hole, and mounting 3 is provided with threaded blind hole. The inner through hole of the variable diameter plug 2 has the same diameter as the threaded blind hole of the fixing piece 3, and the centers of the holes are on the same straight line under the assembling condition. It should be noted that the direction of the thread in the blind hole of the fixing member 3 is opposite to the direction of the external thread of the fixing member 3. And the diameter of the inner through hole of the reducing plug 2 is the same as that of the threaded blind hole of the fixing piece 3 and that of the fixing screw rod 4, and the threads of the blind hole of the fixing piece 3 are matched with those of the fixing screw rod.

As shown in fig. 4 and 5, the embedded part provided by the present invention can be extended.

After the rotating thread of the fixing screw rod 4 is mutually engaged with the thread of the blind hole of the fixing piece 3, the fixing piece 3 and the fixing screw rod 4 are driven to rotate together in one direction, so that the fixing piece 3 is separated from the embedded rod 1 and continuously extends until the fixing piece is abutted to the other side of the template, as shown in fig. 5. At the moment, the side face of the template pressed by the pressing part on the fixing screw rod 4 is rotated, so that the embedded part is fixed on the template.

The utility model provides a technical scheme can also change the pre-buried degree of depth of built-in fitting to the concrete beam of different width outside reducing stopper department increases an impetus for the built-in fitting has bigger application range, operation that can be nimble.

Particularly, the utility model provides an in the scheme, reducing stopper 2 still is provided with the spacing dish 22 of second, and buried pipe 1 still includes first spacing dish 11 in advance, and first spacing dish 11 all inwards caves in under the assembled state with the spacing dish 22 of second spacing dish 22 contain in the sunken intracavity that first spacing dish 11 formed. Because the embedded part shell, including first spacing dish 11 and second spacing dish 22 are all made of plastic, have some elasticity slightly, so when the workman is in the in-process of fixed embedded part on template 5, just can compress tightly the side of first spacing dish 11 and template 5, avoid the liquid infiltration in the concrete embedded part.

In addition, because the reducing plug 2 can be dismantled, after dismantling the template and take off the pull rod, can insert the original position of buried pipe 1 again with reducing plug 2, when follow-up workman mends concrete and tiling like this, because the hole is littleer, more convenient operation, and because the sunken shape of first spacing dish 11 and second spacing dish 22, the concrete of replenishment can be more firm.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
