Abstract
The present invention relates to technical field of buildings, title is a kind of stair built-in fitting of perforation type, including embedded part body, has the bottom of expansion below the embedded part body；It is characterized in that：The embedded part body has upper and lower perforative through hole, there is the first screw thread in the through hole, the embedded part body has the baffle extended to surrounding above and below, there is the dowel extended to surrounding among the embedded part body, it is divided into two parts among the embedded part body, it is that outwardly and inwardly, external inner face and internal outside have the advantages that the second screw thread of cooperation and the stair built-in fitting as the second threaded connection have and be easy installation stair respectively.
Description
Technical field
The present invention relates to technical field of buildings, concretely relate to stair built-in fitting.
Background technology
Stair built-in fitting includes embedded part body, has the bottom of expansion below the embedded part body；The prior art
In, it is welding plane above embedded part body, installation stair seek to stair being welded on welding surface, and when installation just needs to weld
Machine has the shortcomings that inconvenient for use.
Invention content
The mesh of the present invention provides a kind of easy stair built-in fitting of installation aiming at disadvantages mentioned above --- a kind of perforation type
Stair built-in fitting.
The technical solution used in the present invention is：A kind of stair built-in fitting of perforation type, including embedded part body, it is described
There is the bottom of expansion below embedded part body；It is characterized in that：The embedded part body has upper and lower perforative through hole.
Further speaking, there is the first screw thread in the through hole.
Further speaking, the embedded part body has the baffle extended to surrounding above and below.
Further speaking, there is the dowel extended to surrounding among the embedded part body.
Further speaking, be divided into two parts among the embedded part body, be respectively outwardly and inwardly, external inner face and
Internal outside has the second screw thread of cooperation and is threadedly coupled with second.
The beneficial effects of the invention are as follows：Such stair built-in fitting has the advantages that installing stair is easy.
Description of the drawings
Fig. 1 is the vertical section structure schematic diagram that the present invention is mounted on stair.
Wherein；1, embedded part body 2, expansion bottom 3, through hole 4, the first screw thread 5, baffle 6, dowel 7,
Inside 8, external 9, second screw thread.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of stair built-in fitting of perforation type, including embedded part body 1, below the embedded part body
Bottom 2 with expansion；It is characterized in that：The embedded part body has upper and lower perforative through hole 3.
In use, this built-in fitting is prefabricated inside stair preformed layer, above this built-in fitting and the upper surface of stair are at one
In plane, below this built-in fitting and stair below in one plane, i.e., this built-in fitting run through stair thickness direction, installation
It requires have screw rod below stair when stair, screw rod is inserted through in hole, stair are installed, do not have to welding, screw tightening screw rod is solid
It is fixed, have the advantages that easy for installation.
Further speaking, there is the first screw thread 4, the screw rod below such stair to tighten the first screw thread in the through hole
, install more secured.
Further speaking, the embedded part body has the baffle 5 extended to surrounding above and below.
Further speaking, there is the dowel 6 extended to surrounding among the embedded part body.
Installation of embedded parts is more secured in this way.
Further speaking, it is divided into two parts among the embedded part body, is inside 7 and outside 8, external inner face respectively
There is the second screw thread 9 of cooperation with internal outside and be threadedly coupled with second.Entire built-in fitting can be adjusted in this way
Highly, it is suitble to the stair installation of different-thickness, is more convenient.
Above is only a specific embodiment of the present invention, but the structure feature of the present invention is not limited to this, any ability
The technical staff in domain in the field of the invention, made by changes or modifications all cover the present invention the scope of the claims in.
