Background
The house industrialization adopts the industrialized production mode to construct the building, can reduce the cost, improve the efficiency, guarantee the quality, the house industrialization has become the inevitable trend of building industry development, prefabricated stair demolding hoist and mount generally adopt pre-buried rings or pre-buried hanging nuts, the pre-buried hoist and mount of part in the stair need be pre-buried in the component production process, not only can influence stair production efficiency, and this part of burying generally only uses when demolding, cause the wasting of resources, consequently must research and develop the stair demolding hoist that can reuse, the construction installation is convenient, in order to satisfy the requirement of improving production efficiency, resources are saved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a but reuse's prefabricated stair demolding hoist structure, its connection simple structure, simple to operate can effectively solve the construction process many, the serious scheduling problem of wasting of resources.
In order to achieve the purpose, the utility model adopts the following technical proposal:
a recyclable prefabricated staircase demolding hanger structure comprises a staircase board and a hanger;
mounting holes are arranged on two sides of the stair board, and the mounting holes are cylindrical and gradually increase in diameter from one end to the other end; the mounting hole is internally provided with an embedded rod corresponding to the section of the mounting hole, the diameter of the embedded rod is gradually increased from one end to the other end, the end with the larger diameter of the embedded rod is a first end, the other end of the embedded rod is a second end, and the second end is provided with a screw hole;
the lifting appliance is L-shaped and comprises a transverse plate at the top and a vertical plate at the bottom, wherein the vertical plate is provided with a round hole and is fixedly connected with the screw hole through a fixing bolt; the transverse plate is provided with a hanging hole.
Furthermore, the transverse plate is provided with a plurality of horizontally arranged hanging holes.
Furthermore, the transverse plate extends upwards to be provided with a stiffening plate, and the hanging holes are formed in the stiffening plate.
Further, the diameter of the first end is 70mm, and the diameter of the second end is 50 mm.
The utility model has the advantages that: the utility model discloses but reuse's prefabricated stair demolding hoist structure, it can reduce the prefabricated stair built-in fitting, utilizes stair mounting hole and mounting hole built-in fitting, through bolted connection, links into an organic whole hoist and mounting hole built-in fitting, and the joint construction is simple, simple to operate, and but reuse, and it is many to effectively solve the construction process, the serious scheduling problem of wasting of resources.

Detailed Description
In order to make the technical solution and the advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the following embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-2, the utility model provides a prefabricated staircase demolding hanger structure which can be repeatedly used, comprising a stair tread 1 and a hanger 2.
The two sides of the stair board 1 are provided with mounting holes 11, the mounting holes 11 are cylindrical, and the diameter of the mounting holes is gradually increased from one end to the other end. Be equipped with the pre-buried pole 3 that corresponds with this mounting hole 11 cross-section in this mounting hole 11, this pre-buried pole 3's diameter also for following one end and to the other end crescent, and the one end that this pre-buried pole 3 diameter is big is first end 31, and the other end is second end 32, and this second end 32 has the screw. In one embodiment, the first end 31 is 70mm in diameter and the second end 32 is 50mm in diameter.
This hoist 2 is the L type, including the diaphragm 21 at top and the riser 22 of bottom, this riser 22 is equipped with round hole 23, through fixing bolt 4 and this screw fixed connection, because fixing bolt 4 is connected with the little second end 32 of diameter, hoist 2 can not drop when the atress. The transverse plate 21 is provided with hanging holes 24, preferably, the transverse plate 21 is provided with a plurality of hanging holes 24 which are horizontally arranged, and the requirement of the gravity center of prefabricated stairs with different sizes can be met. Furthermore, the transverse plate 21 extends upward to form a stiffening plate 25, and the hanging hole 24 is formed in the stiffening plate 25.
The utility model provides a but reuse's prefabricated staircase demolding hoist structure, its advantage: the utility model discloses a mounting hole is required for the installation of prefabricated staircase, the utility model discloses become the pre-buried pole of mounting hole into the demolding hoist, can effectively improve and bury a utilization efficiency, still reducible piece quantity of burying reduces the wasting of resources. The lifting appliance has the advantages that the upper part of the lifting appliance is provided with the plurality of lifting holes, the gravity center requirements of the prefabricated stairs with different sizes can be met, the lifting appliance can be connected with the embedded rod into a whole only through bolt assembly, the connection structure is simple, the installation is convenient, and the problems that the field construction workload is large and the quality is not easy to guarantee can be effectively solved.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the structure of the present invention in any way. Any simple modification, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention all still fall within the scope of the technical solution of the present invention.
