Description
Technical field
The utility model is related to construction engineering technical field, is related to a kind of hardware being embedded in concrete, especially
It provides a kind of bolt type channel-section steel embedded parts.
Background technology
Built-in fitting is that the component being pre-installed in concealed work is exactly the component and fitting disposed when structure is poured, is used for
The overlap joint of building body structure and attachment formation is poured, so that the installation of field engineering Equipment Foundations fixes built-in fittings mostly by metal
Manufacture.
It is groove type embedded part that application is more on the market at present, and groove type embedded part is a kind of new product, it is adaptable in groove
High-mechanic requirement on steel horizontal stroke, longitudinal direction.
Groove type embedded part is made up of a C-shaped channel steel and dowel, and connected other structures part is substantially
It is fixed using bolt and the nut of matching with it, and it is most of using directly passing through welding between dowel and C-shaped channel steel
Or the mode of riveting is fixed, the bottom termination of dowel uses cold-heading termination, and complex manufacturing is time-consuming, is unfavorable for
The control of quality, and bearing capacity is not strong.
The content of the invention
In order to overcome drawbacks described above, the utility model provides a kind of bolt type channel-section steel embedded parts, it is to avoid directly utilize welding
With riveting stress, concise production process, bearing strength is high, and quality is easily controllable.
The purpose of this utility model is achieved through the following technical solutions：A kind of bolt type channel-section steel embedded parts, including c-type
Three identical circular holes are provided with the web of channel-section steel, dowel, circular hole, wherein C-shaped channel steel, each circular hole is correspondingly arranged on one
Individual identical dowel, the dowel is divided into top and threaded shank, and top diameter is more than the diameter of circular hole, and the diameter of threaded shank is less than
The diameter of circular hole, threaded shank is provided with screw thread close to bottom termination, the nut that has with screw thread corresponding matching, the screw thread of threaded shank with
Nut is carried out coordinating the bottom for making dowel to be nut termination, and the threaded shank of dowel is all poured into when concrete is poured,
Nut is directly wrapped in concrete simultaneously, makes the bearing strength of whole built-in fitting higher, between increase dowel and mixed mud
Frictional force and concrete to the mechanical snap power of dowel, through circle at the front openings that the threaded shank of dowel passes through C-shaped channel steel
On the web that C-shaped channel steel is stayed at the top of hole, dowel, then welded
It is fixed.
The beneficial effects of the utility model are：First, dowel is penetrated from the web of C-shaped channel steel and welded again, is only served
Fixation, it is quick for installation without welding stress；2nd, the bottom of dowel is using nut as termination, and resistance to tensile strength is high, quality
Easily controllable, firmness is higher.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is the overall top view of the utility model；
Fig. 3 is the utility model dowel structural representation.
Embodiment
With reference to embodiment and compare accompanying drawing and say that the utility model is described further.
Specific embodiment of the present utility model is as follows：
Embodiment：As shown in Figure 1, Figure 2, Figure 3 shows, a kind of bolt type channel-section steel embedded parts, including C-shaped channel steel 1, dowel 2, circular hole
3, three identical circular holes 3 are wherein provided with the web of C-shaped channel steel 1, each circular hole 3 is correspondingly arranged on an identical anchor
Muscle 2,2 points of the dowel is top 21 and threaded shank 22, and the diameter of top 21 is more than the diameter of circular hole 3, and the diameter of threaded shank 22 is small
In the diameter of circular hole 3, threaded shank 22 is provided with screw thread 23 close to bottom termination, has nut 24, spiral shell with the corresponding matching of screw thread 23
The screw thread 23 of bar portion 22 carries out coordinating the bottom for making dowel 2 to be the termination of nut 24, dowel 2 when concrete is poured with nut 24
Threaded shank 22 all pour into, while nut 24 is directly wrapped in concrete, make the resistance to tensile strength of whole built-in fitting
It is higher, frictional force and coagulation between increase dowel 2 and mixed mud
Mechanical snap power of the soil to dowel 2.
Circular hole 3, dowel are passed through at the front openings that the threaded shank 22 of dowel 2 is passed through into C-shaped channel steel 1 in implementation installation process
2 top 21 is stayed on the web of C-shaped channel steel 1, is then carried out
It is welded and fixed.
Claims (1)
1. a kind of bolt type channel-section steel embedded parts, including C-shaped channel steel, dowel, it is characterised in that：Also include circular hole, screw thread, nut,
Three identical circular holes are wherein provided with the web of C-shaped channel steel, each circular hole is correspondingly arranged on an identical dowel, institute
State dowel and be divided into top and threaded shank, top diameter is more than the diameter of circular hole, and the diameter of threaded shank is less than the diameter of circular hole, screw rod
