Furthermore, a cover plate is arranged at the top of the embedded cylinder.

Furthermore, pull rings are arranged at the joints of the three connecting rods.

Furthermore, the bottom of the inserted link of the stabilizing claw is provided with a threaded hole, and a lower nut is rotationally connected in the threaded hole.

Further, the nut diameter of the lower nut is larger than that of the inner inserting pipe so as to fix the independent pipe piece.

Furthermore, through holes are formed in the joints of the three connecting rods, screw rods are inserted into the through holes in the two different stabilizing claws, and an upper locking nut and a lower locking nut are respectively arranged at the two ends of each screw rod.

The utility model has the advantages that:

the utility model discloses the mode that utilizes grafting and screw thread locking has realized the fixed of pre-buried external member, and the dismouting is also convenient, and the cost of manufacture is low, is fit for popularizing and applying.

In the figure: 11 independent segments, 12 inner inserting tubes, 21 pull rings, 22 connecting rods, 23 inserting rods, 24 threaded holes, 25 lower nuts, 26 screw rods, 27 upper locking nuts and 28 lower locking nuts.

Detailed Description

As shown in fig. 1 to 4, a reusable hole pre-buried kit comprises a pre-buried cylinder and a stable paw, wherein the pre-buried cylinder comprises an independent segment 11 and an inner insert tube 12. The inner wall of each independent duct piece is fixedly connected with an inner inserting pipe 12, and the three independent duct pieces in the annular array form a closed annular ring. The stabilizing paw comprises a pull ring 21, three connecting rods 22 are arranged at the bottom of the pull ring, and an inserting rod 23 is vertically connected to each connecting rod and inserted into the insertion tube 12.

The top of the embedded cylinder is provided with a cover plate to prevent concrete from entering the embedded cylinder.

The working mode is as follows:

1) firstly, the reserved position of a hole is determined, and the pre-buried process is firstly assembled.

2) The pre-buried external member is wrapped by the transparent adhesive tape after the assembly is completed (the concrete construction is prevented from leaking slurry).

3) And (5) pre-embedding and fixing, and fixing and positioning by using four iron nails.

4) Aim at pre-buried pipe fitting edge with the apron and add the lid fixed, prevent that the concrete from falling into pre-buried section of thick bamboo, avoid demolising for the later stage and cause the difficulty.

5) When the pipe piece is dismantled, the cover plate is taken off firstly, then the stabilizing claw in the embedded part is pulled out, and then a small hammer is used for tapping one side of the three independent pipe pieces to complete the dismantling work.

The scheme takes DN200mm floor opening embedded part as an example, and other diameter opening embedded parts are used in the same way.

1. Material preparation

Materials: DN200mm steel tube and steel tube are 200mm long, DN20mm steel tube is 30mm long, phi 14 round steel is 600mm long, and phi 8 steel bar is 200mm long.

2. Principle of fabrication

1) A360-degree section of the DN200mm steel tube is equally divided into 3 parts according to 120 degrees, and the cut is cut into an angle of 45 degrees, so that the steel tube is easy to remove.

2) And after the steel pipe is cut into equal parts, welding a DN20mm steel pipe on the inner side of the steel pipe, and welding joints at the middle lower part of the concave side of the steel pipe.

3) And (3) manufacturing a stable paw: three phi 14 steel pipes are cut out, the length of the three phi 14 steel pipes is 200mm, the center point of a steel pipe made of DN200mm steel is used as a center, each claw is separated by 120 degrees and just inserted into an inner welding steel pipe, the length of each claw is welded according to the steel pipe (DN20mm), and a handle is welded on the claw.

4) And manufacturing the cover plate by using the waste template on site. Grooves with the depth of 200mm and 5mm are formed around the cover plate, so that the circular cover can be conveniently covered and fixed.

A second embodiment of the stabilizing finger is shown in fig. 5 and differs from the first embodiment in that the bottom of the shank of the stabilizing finger is provided with a threaded hole 24 in which a lower nut 25 is rotatably attached, the lower nut having a nut diameter larger than the inner insert 12 for securing the individual segments 11 against detachment from the stabilizing finger.

A third embodiment of the stabilizing paw is shown in figures 6 and 7.

The stabilizing claw does not have a pull ring 21 which is convenient for people to grab, the stabilizing claw is in the form that an upper pipe orifice and a lower pipe orifice of an inner inserting pipe are respectively inserted with one stabilizing claw, a through hole is formed in the center of a connecting rod, a screw rod 26 is inserted in the through holes in two different stabilizing claws, and an upper locking nut 27 and a lower locking nut 28 are respectively arranged at two ends of the screw rod. Like this through the independent section of jurisdiction of two stable paws chucking pre-buried section of thick bamboos for three independent section of jurisdiction forms a complete ring mechanism, and convenient pre-buried.

In addition to the technical features described in the specification, the technology is known to those skilled in the art.
