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, such as the diameter of the temporary fixing screw rod is small, but the reserved through hole is too large, the temporary fixing screw rod is only fixed by the screw thread in the plastic protective cover, and because the concrete is rapidly and largely poured downwards on the site, the embedded part is easy to deviate from the position and even be damaged by washing.

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.
As shown in fig. 5, the utility model provides an improved generation built-in fitting for building includes: the embedded part comprises an embedded part body 1, a rectangular through hole cavity 11, a square nut 111, a rectangular through hole cavity end cover 112, a reducing plug 12 and a second positioning plate 13.
As shown in fig. 1 to 4, the second positioning plate 13 is disposed at one end of the embedded part body 1, and the rectangular through hole cavity 11 is disposed at the other end of the embedded part body 1. The square nut 111 is received in the rectangular through hole cavity 11. The second positioning plate 13, the embedded part body 1 and the square nut 111 are all provided with circular through holes, and the centers of the three through holes are on the same straight line in an assembling state.
The rectangular through hole cavity end cover 112 is buckled at one end, far away from the embedded part body 1, of the rectangular through hole cavity 11, an end cover protrusion 1121 is arranged outwards of the rectangular through hole cavity end cover 112, a blind hole with internal threads is arranged on the end cover protrusion 1121, and the center of the blind hole of the end cover protrusion 1121 and the center of the through hole of the embedded part body 1 are on the same straight line.
As shown in fig. 4, the reducing plug 12 includes a section of cylinder, a plurality of supporting members 121 are radially disposed along the outside of the cylinder, a first positioning plate 122 is disposed at one end of the reducing plug, and the outer diameter of the first positioning plate 122 is greater than the diameter of the through hole of the second positioning plate. The straight of the through hole of the second positioning disc 13 is matched with the diameter of the pull rod. Particularly, the inner diameter of the reducing plug 12 is matched with the inner diameter of the fixing screw, and the inner diameter of the reducing plug 12 plus 2 times of the thickness of the cylinder plus 2 times of the height of the support 121 is just the diameter of the through hole of the second positioning disk 13. The reducing plug 12 is clamped at the through hole of the second positioning plate 13.
Therefore, when using the utility model provides a during the built-in fitting, when the built-in fitting is fixed on the template, have at least two atress departments of reducing stopper 12 and rectangle through hole chamber end cover 112, when the concrete under the construction, the built-in fitting will be stabilized a lot. When the concrete is solidified and the pull rod is required to be installed after the formwork is dismantled, the reducing plug is taken down. Because the utility model provides a support piece 121 is used to the reducing stopper for the frictional force of reducing stopper 12 and built-in fitting body 1 is not big, can take out very easily. During the in-service use, the gap between the fixed screw that operating personnel utilized manufacturing tolerance to produce and reducing stopper 12 can make the fixed screw can move about a little in the through-hole of reducing stopper 12, and in the in-process of taking out the fixed screw, a pressure fixed screw is pressed downwards a little, and the end face that makes the screw thread of fixed screw catch reducing stopper 12 in the through-hole of built-in fitting body 1 can take out reducing stopper 12.
Preferably, the first positioning plate 122 of the present invention is made of plastic material and is recessed inwards, and this structure has at least 2 benefits: 1. when the embedded part is fixed with the template, only one layer of the edge of the inwards-recessed first positioning disc 122 contacts the template, so that the pressure intensity is higher under the same pressure, a proper sealing effect can be realized, and the fact that liquid in concrete does not permeate into the template is really found in an experiment; 2. after the construction is completed and the cantilever beam is removed, the concrete is required to be repaired and subsequent procedures such as tiling are carried out, and the first positioning disc 122 is inwards sunken, so that more concrete can be contained in the part, and the concrete is more firmly bonded and is not easy to fall off.
As shown in FIG. 2, the utility model discloses a square nut 111 has changed the fixation nut who originally is similar to the hexagon, sets up like this and can let built-in fitting stability better.
As shown in fig. 6, the rectangular through hole cavity end cap 112 and the rectangular through hole cavity 111 paper in the solution of the present invention adopt a fastening or direct fixing connection manner, so that the rectangular through hole cavity end cap 112 and the rectangular through hole cavity 111 are not well connected to cause slipping when the fixing screw is tightened.
To sum up, the utility model provides a pair of improved generation built-in fitting compares with prior art, and is higher with the stability of template, is difficult to the accident in the use to discovery and prior art in the experiment compare the condition that the concrete seepage can not appear basically and advance the through-hole. Furthermore, the design provided by the scheme can also optimize subsequent construction quality, so that the supplemented concrete is not easy to fall off, and if the outer wall has the requirement of tiling, the bricks at the through holes of the embedded part are not easy to fall off and the normal concrete wall has no difference.
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.
