Abstract
The utility model relates to a toothed dovetail groove embedded part and belongs to the field of general engineering. The toothed dovetail groove embedded part comprises C-shaped channel steel. The inner end face of the open face flanging of the C-shaped channel steel is provided with ladder-shaped teeth. According to the toothed dovetail groove embedded part, the inner end face of the open face flanging of the C-shaped channel steel is provided with the ladder-shaped teeth, and the ladder-shaped teeth are fixedly connected with the back face of the C-shaped channel steel through a rivet, thus, such a structure not only can be used for enabling a connecting bolt to be accurately and movably adjusted along the longitudinal direction of the channel steel but also has higher bearing capacity. The toothed dovetail groove embedded part is suitable for the high-bearing requirements on the channel steel in the longitudinal direction. Loads which reach up to 3kN even can be absorbed by the high-performance channel steel. The accurately used bearing capacity is ensured by the specially designed side teeth; and the danger that slippage occurs is eliminated.
Description
Technical field
The utility model relates to a kind of band tooth dovetail groove built-in fitting, belongs to the common engineering field.
Background technology
In project building construction, especially in the curtain wall engineering construction, often can use built-in fitting.The building curtain wall built-in fitting is the important component of curtain wall built-in fitting, and its function of tonic chord is load and the effect that curtain wall is born, by built-in fitting effectively, reliable delivery is on agent structure.China's common built-in fitting that adopts in building curtain wall comprises C type channel-section steel at present, holdfast, bolt, and the opening surface flanging inner face of C type channel-section steel is zigzag, anchor pole is positioned at the C type channel-section steel back side; Bolt is arranged in the inboard chute of C type channel-section steel.The built-in fitting of this structure has the not strong shortcoming of interlock effect, and controllability is not strong, mechanical property is bad, and a little less than the bearing capacity, when wall construction, security performance is not ideal enough.
Summary of the invention
The purpose of this utility model is to provide a kind of result simple, and bearing capacity is strong, and adjustability is strong, convenient a kind of band tooth dovetail groove built-in fitting of realizing that multidimensional is installed.
Technical solution
The utility model comprises C type channel-section steel, and the opening surface flanging inner face of described C type channel-section steel is provided with the trapezoidal shape teeth.
The opening surface flanging of the C type channel-section steel of describing is the right angle flanging.
The opening surface flanging inner face of the utility model C shaped steel groove is for being provided with trapezoidal chute-like teeth, because holdfast is fixedly connected on the back side of C type channel-section steel, this structure can make connecting bolt along groove to accurately mobile adjustment, has again higher supporting capacity.Make it to be applicable to the high-bearing requirement on the channel-section steel longitudinal direction.These high-performance channel-section steels even can absorb load up to 3kN.The heel teeth of particular design has guaranteed the supporting capacity of accurate use, has eliminated the danger that slippage occurs.

Fig. 2 is the utility model partial sectional view.
The specific embodiment
Chute 4 opening surface flangings 3 inner faces of the utility model C type channel-section steel 1 divide and are being furnished with trapezoidal shape teeth 6, and trapezoidal shape teeth 6 highly are 1-6mm, and the stepped tooth tooth top width is 1-4mm, and space width is 4-8mm, and the ramp angles of stepped tooth is 40 °-80 °.The opening surface flanging 3 of the C type channel-section steel 1 of describing is the right angle flanging, and holdfast 2 is positioned at the C type channel-section steel back side; Bolt 5 is arranged in the inboard chute of C type channel-section steel.Band tooth dovetail groove type built-in fitting can be realized the hard-wired all conditions of lifting guide rail: three-dimensional moving band high bearing capacity.These channel-section steels also are applicable to vertical installation, as in bearing the concrete column of longitudinal load-bearing.
