Abstract
The utility model discloses a kind of embedded part for building, include head disk, head disk is distributed with fixed hole and its upper surface forms hollow cylinder along wherein axle annular, and hollow cylinder inwall is provided with internal thread, head disk upper surface also forms outwards to be dispersed and be evenly distributed three projections along its central shaft, height of projection is 1.5 ~ 2mm and its cross-sectional shape approximate right angle triangle, hypotenuse be indent arc-shaped side and triangle wherein a right angle side and head disk upper surface perpendicular, right-angled triangle indent arc-shaped side radian direction is identical with the internal thread direction arranged in hollow cylinder.The utility model structure head disk upper surface forms the leg-of-mutton projection of cross-sectional shape approximate right angle, and make when pre-buried more firm, and not easily skid when installing, in addition, protruding structure size can meet cold-heading once-through, and cost of production is low.
Description
technical field:
The utility model relates to installation fitting for building, particularly relates to a kind of embedded part for building.
background technique:
In construction industry; in order to install object on wall; usually need to fix by nailing or by imbedding embedded part to carry out installation in wall; and existing embedded part structure is all fairly simple; and nailing or common embedded part skid when usually can twist screw in installation process; and the connection between body of wall is insecure, effect is installed in impact.
In addition, traditional embedded part, in order to reduce cost of production, normally adopts cold-extrusion shaping, if therefore embedded part structure is modified many can cause it cannot cold upset forming, just considerably increase cost of production according to casting technique.
model utility content:
The purpose of this utility model is exactly to solve existing issue, and provides a kind of embedded part for building, and make when pre-buried more firm, and not easily skid when installing, in addition, protruding structure size can meet cold-heading once-through, and cost of production is low.
Technology solution of the present utility model is as follows:
A kind of embedded part for building, it includes head disk, described head disk is distributed with fixed hole and its upper surface forms hollow cylinder along wherein axle annular, and described hollow cylinder inwall is provided with internal thread, the one side that described head disk forms hollow cylinder also forms and outwards disperses and be evenly distributed three projections along its central shaft, described protruding one end is connected with hollow cylinder outer surface, its the other end is mutually concordant with head disk outer periphery, described height of projection h is 1.5 ~ 2mm and its cross-sectional shape approximate right angle triangle, described hypotenuse be indent arc-shaped side and triangle wherein a right angle side and head disk upper surface perpendicular, described right-angled triangle indent arc-shaped side radian direction is identical with the internal thread direction arranged in hollow cylinder.
As preferably, described head disk offers the counterbore corresponding with hollow cylinder interior threaded hole position, and communicates with tapped hole.
As preferably, the width b of described projection is 1/15 ~ 1/11 of head disk diameter d.
The beneficial effects of the utility model are:
In the embedded part for building of the utility model structure, head disk upper surface forms the leg-of-mutton projection of cross-sectional shape approximate right angle, installing and using in process, convex portion is imbedded in construction wall, what whole embedded part was combined with construction wall in use is more firm, simultaneously, convex cross section profile approximate right angle triangle, therefore can not there is because dynamics of tightening grasps bad the phenomenon that embedded part entirety is skidded when mounted, in addition, protruding structure size can meet cold-heading once-through, and cost of production is low.
accompanying drawing illustrates:
Fig. 1 is the utility model structure front schematic view;
Fig. 2 is the utility model schematic top plan view;
Fig. 3 is the partial cutaway schematic of Fig. 2.
In accompanying drawing: 1, head disk; 2, hollow cylinder; 3, protruding; 11, fixed hole; 12, counterbore.
embodiment:
As Figure 1-3, a kind of embedded part for building, it includes head disk 1, described head disk 1 is distributed with fixed hole 11 and its upper surface forms hollow cylinder 2 along wherein axle annular, and described hollow cylinder 2 inwall is provided with internal thread, the one side that described head disk 1 forms hollow cylinder 2 also forms and outwards disperses and be evenly distributed three projections 3 along its central shaft, described protruding 3 one end are connected with hollow cylinder 2 outer surface, its the other end is mutually concordant with head disk 1 outer periphery, described protruding 3 height h are 1.5 ~ 2mm and its cross-sectional shape approximate right angle triangle, described hypotenuse be indent arc-shaped side and triangle wherein a right angle side and head disk 1 upper surface perpendicular, described right-angled triangle indent arc-shaped side radian direction is identical with the internal thread direction arranged in hollow cylinder 2.
Particularly, described head disk 1 offer the counterbore 12 corresponding with hollow cylinder 2 interior threaded hole position and communicate with tapped hole.
Particularly, the width b of described protruding 3 is 1/15 ~ 1/11 of head disk 1 diameter d, if the size between the width b of protruding 3 and head disk 1 diameter d is too close, then makes protruding 3 direct cold-heading moldings have difficulty, cannot make.
In the embedded part for building of the utility model structure, head disk 1 upper surface forms cross-sectional shape approximate right angle leg-of-mutton protruding 3, installing and using in process, head disk 1 exposes body of wall, hollow cylinder 2 and protruding 3 parts are imbedded in construction wall, only by object by being connected with embedded part with the bolt that hollow cylinder 2 inner bolt hole matches, just need can reaching and fixing with wall connecting.
It is more firm that the shaping projection 3 of head disk 1 upper surface makes whole embedded part be combined with construction wall in use, simultaneously, protruding 3 cross-sectional shape approximate right angle triangles, therefore can not there is because the dynamics of tightening of bolt grasps bad the phenomenon that embedded part entirety is skidded when mounted, in addition, the size design of protruding 3 structures can meet cold-heading once-through, and Mold Making is convenient, and cost of production is low.
The foregoing is only preferred embodiment of the present utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
