Description

Technical Field

[0001] The utility model belongs to the technical field of steel tube trusses, and in particular relates to a steel tube truss and a concrete composite plate with the steel tube truss structure. Background Art

[0002] Concrete composite slabs are made by inserting steel pipes or steel bars into the concrete slabs to increase the strength of the slabs themselves and strengthen the connections between the slabs.

[0003] The current steel tube truss is composed of horizontally arranged steel tubes and continuously bent web reinforcements on both sides. The existing patent CN217652152U discloses a steel tube reinforcement frame, which describes: "The arc section at the upper end of each web reinforcement is higher than the steel tube, and the web reinforcements on both sides of the arc section are welded to the steel tube". The connection position has less contact and the connection strength is not high. The steel tube and the web reinforcement are easily separated when collided, which poses certain safety hazards.

[0004] Therefore, in order to solve the above problems, it is necessary to design a steel tube truss and a concrete composite slab with a steel tube truss structure. Utility Model Content

[0005] The utility model aims to provide a steel tube truss and a concrete composite slab with the steel tube truss structure, so as to solve the technical problem that the steel tube and the web reinforcement are easily separated.

[0006] In order to solve the above technical problems, the utility model provides a steel tube truss, comprising:

[0007] A steel pipe and web reinforcements arranged on both sides of the steel pipe; wherein

[0008] The abdominal muscles are in a continuously bent wave shape; and

[0009] The web ribs include: a plurality of bent portions formed by bending;

[0010] The bent portion at the top is connected to the side surface of the steel pipe.

[0011] Furthermore, the angle between the center lines of the two abdominal muscles is 20° to 30°.

[0012] Furthermore, the ratio of the diameters of the steel pipe and the web reinforcement is 4.5:1.

[0013] Furthermore, the web ribs further include: a plurality of straight portions connected to the bent portions;

[0014] The angle between the center lines of adjacent straight portions is 20° to 80°.

[0015] Furthermore, filler is provided inside the steel pipe.

[0016] On the other hand, the utility model also provides a concrete composite slab with a steel tube truss structure, comprising:

[0017] A plate body and a plurality of steel tube trusses equidistantly arranged on the plate body.

[0018] Furthermore, the bent portion at the bottom is embedded in the plate body.

[0019] Furthermore, the plate body is provided with a plurality of equidistantly arranged transverse ribs;

[0020] The transverse ribs penetrate the plate body.

[0021] The beneficial effects of the utility model are:

[0022] (I) The utility model increases the contact area compared with the traditional steel tube truss by connecting the bent part with the side of the steel tube, so as to achieve the effect of convenient welding and integrated welding, making the connection between the steel tube and the web more stable and not easy to separate.

[0023] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by practicing the utility model.
