Abstract
A kind of lightweight steel joist system, including day ground joist and several centre keels, its ground joist includes ground keel and top keel, the centre keel is arranged between ground keel and top keel, the bottom of the ground keel and top keel is equipped with several reinforcing ribs, and the centre keel is equipped with groove corresponding with reinforcing rib with the base contact surface of ground keel and top keel.The utility model can make centre keel top to world keel bottoms, improve support force.
Description
Technical field
The utility model relates to a kind of light steel construction field, in particular to a kind of lightweight steel joist system.
Background technique
As shown in figure 4, the section of prior art lightgage steel joist is plane, lightgage steel joist bottom is equipped with reinforcing rib, centre keel
It pushes up onto the reinforcing rib of day ground joist, centre keel and day ground joist are connected with gap, can not support to world keel bottoms, make to erect
The support force of keel is greatly lowered.
Summary of the invention
The purpose of this utility model is to provide a kind of lightweight steel joist system, it can be achieved that centre keel can be pushed up to day pheretima
Support force is improved in bone bottom.
To achieve the above object, the utility model uses following technical scheme:
A kind of lightweight steel joist system, including day ground joist and several centre keels, day ground joist include ground keel and
Top keel, the centre keel are arranged between ground keel and top keel, the ground keel and top keel
Bottom is equipped with several reinforcing ribs, and the centre keel is equipped with and reinforcing rib phase with the base contact surface of ground keel and top keel
Corresponding groove.
Further, the reinforcing rib is arc-shaped or triangle or trapezoidal.
Further, the bottom surface both side of the ground keel and top keel is equipped with a chamfering or fillet, and described is perpendicular
Keel correspond to and are provided with the first notch at chamfering or fillet, and first notch is greater than chamfering or fillet.
Further, the upper end of the ground keel and top keel is provided with opposite with centre keel with centre keel contact surface
The second notch is answered, second notch is through to the bottom of bottom surface keel and top keel for centre keel.
After adopting the above technical scheme, the utility model can realize that centre keel can be pushed up to world keel bottoms, support is improved
Power.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
As shown in Figure 1 to 4, present embodiment discloses a kind of lightweight steel joist systems, including day ground joist and perpendicular dragon
Bone 2, day ground joist include top keel 1 and ground keel 3, and centre keel 2 is arranged between top keel and ground keel 3, are erected
Self-drilling screw is fixed between keel 2 and top keel and ground keel 3.
The bottom of top keel 1 and ground keel 3 is provided with several reinforcing ribs 31, and reinforcing rib 31 is for increasing top dragon
The intensity of bone 1 and ground keel 3, reinforcing rib 31 can be round, triangle or trapezium structure, the corresponding top of centre keel 2 dragon
Bone 1 is provided with corresponding groove 21 with the position of the reinforcing rib 31 of ground keel 3, and groove 21 is opened up on centre keel 2 so as to perpendicular dragon
Bone 2 can circumvent the top to the bottom of top keel 1 and ground keel 3 of reinforcing rib 31.
Top keel 1 and the two sides of the bottom of ground keel 3 are equipped with corresponding chamfering or fillet 32, with top keel 1 and
There are also the first notch 22 on the position of the corresponding chamfering of the centre keel 2 that ground keel 3 connect or fillet 32, the first notch 22 is greater than to fall
Angle or fillet 32 avoid on the top to chamfering or fillet 32 of centre keel 2, and centre keel 2 can not be pushed up to top keel 1 and ground keel 3
Bottom, cause and bottom be every sky, make self-drilling screw not only and need to act on connection be also subjected to vertical supporting by shearing force, drop
The support force of low centre keel 2.
Top keel 1 offer corresponding with 2 size of centre keel with the contact surface of the upper end of ground keel 3 and centre keel 2
The second notch, the second notch can allow centre keel 2 lead directly to top keel 1 and ground keel 3 bottom.
In conclusion the utility model can realize that centre keel can be pushed up to world keel bottoms, support force is improved.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
