The chinese patent of bulletin number CN219118765U discloses a simple and easy pre-buried sleeve mounting structure, utilizes fixed iron nail to fix spacingly, ties respectively on four fixed iron nails, connects the location iron nail at the other end of four tie wires and carries out mark point calibration, and this mode is implemented still relatively complicated, and the location iron nail is located the sleeve pipe top, and the mark point is located the die block board, and constructor's sight deviation has greatly influenced the accuracy of location iron nail, still appears positional deviation easily.
Disclosure of Invention
In order to solve the technical problems, the utility model provides a fixing structure of a cast-in-place concrete embedded sleeve, which is rapid and accurate in positioning, reduces the construction time of sleeve fixing and has high turnover utilization rate.
In order to achieve the technical purpose, the utility model adopts the following scheme:
the fixing structure of the cast-in-place concrete embedded sleeve comprises a sleeve and a bottom template; still include locating bottom plate, fixing bolt, cope match-plate pattern and stopper, locating bottom plate connects on the die block board, locating bottom plate upper surface and fixing bolt one end fixed connection, and fixing bolt's the other end is connected with the cope match-plate pattern, and the lower surface mounting of cope match-plate pattern has the stopper, and the lateral wall and the sheathed tube inside wall of stopper closely laminate, and the sleeve pipe is placed on the die block board.
Compared with the prior art, the utility model has the beneficial effects that: the positioning bottom plate is fixed at the position of the marking point, the position of the preformed hole is accurately positioned, the sleeve is quickly clamped through the limiting block by taking the fixing bolt as the axis, the upper die plate is limited and fixed, the fixed installation of the sleeve is accurately and quickly completed, the working efficiency is improved, and meanwhile, the fixing structure can be repeatedly utilized for many times, and the turnover utilization rate is high; the problem that the sleeve is not easy to fix under the condition of limited field space is solved, and the problem that the floor slab leaks due to the fixed sleeve is also solved.
The preferable scheme of the utility model is as follows:
the upper template is a square template, and the side length of the square is the same as the outer diameter of the sleeve.
The limiting blocks are symmetrically arranged in pairs about the center of the upper end face of the sleeve, and the distance between the outer side walls of the two limiting blocks in each group is the same as the inner diameter of the sleeve.
The set screw is collinear with the axis of the sleeve.

Detailed Description
The present utility model will be described in detail with reference to the following embodiments for a full understanding of the objects, features and effects of the present utility model, but the present utility model is not limited thereto.
As shown in fig. 1 to 3, the fixing structure of the cast-in-place concrete embedded sleeve provided by the utility model comprises a bottom template 1, a sleeve 6, a positioning bottom plate 2, a fixing bolt 3, an upper template 4, a limiting block 5 and the like, wherein the positioning bottom plate 2 is fixed at a mark point of the bottom template 1, the positioning bottom plate 2 is fixedly connected with one end of the fixing bolt 3, the upper template 4 is penetrated and arranged at the other end of the fixing bolt 3, the limiting block 5 distributed in a cross shape is fixed on the lower surface of the upper template 4, the outer side wall of the limiting block 5 is tightly attached to the inner side wall of the upper part of the sleeve 6, and the lower end of the sleeve 6 is placed on the bottom template 1.
In the field construction process, the positioning bottom plate 2 is fixed at the marking point of the bottom template 1 through dovetail wires or wood screws, and the fixed bolts 3 welded on the positioning bottom plate 2 are opposite to the marking point, namely the positioning center of the sleeve 6. The upper end of the fixing bolt 3 defines the height position of the upper template 4 through a nut. Preferably, the upper template 4 adopts a square wood template, the side length is the outer diameter of the sleeve, two pairs of limiting blocks 5 are symmetrically arranged about the fixing bolt 3, the distance between the outer side walls of the two limiting blocks 5 of each pair is the same as the inner diameter of the sleeve 6, and the limiting blocks 5 are tightly attached to the inner wall of the sleeve 6. The diameter of the through hole formed in the upper die plate 4 is the same as the outer diameter of the fixing bolt 3, so that the poured concrete is prevented from falling into the sleeve 6.
When the concrete pouring device is used, the position of the upper template is adjusted according to the height of the sleeve 6, the upper template 4 can only be adjusted in height and cannot move left and right, so that the position of the sleeve 6 is fixed, the positioning is accurate, and the position and deformation are not easy to move during concrete pouring. When the structure is jointly installed in a plurality of casings in a pipe well, compared with the traditional multi-casing fixing method, the structure can reduce the use of fixing measure materials.
The utility model reduces the construction time for fixing the sleeve, improves the working efficiency of workers, has high turnover rate, high mounting and dismounting speed and high recycling rate, saves manpower and material resources, solves the problem that the sleeve is not easy to fix under the condition of limited field actual space, and simultaneously solves the leakage problem caused by fixing the sleeve.
Finally, it should be noted that: the above list is only a preferred embodiment of the present utility model, and it is understood that those skilled in the art can make modifications and variations thereto, and it is intended that the present utility model be construed as the scope of the appended claims and their equivalents.
