Description
Technical Field
The utility model relates to the field of engineering construction, in particular to a steel bar truss structure.
Background
The steel bar truss is formed and processed in a background processing field, and the length can be prefabricated. In order to provide construction efficiency, the steel bar truss is often prepared together with the bottom die, is directly installed after being transported to a construction site, and is poured with concrete after customer acceptance is finished. After the construction of the traditional steel bar truss is finished, the template cannot be removed, so that the cost of the template is high. Many removable forms have been developed over the years, but the construction is mostly more complex.
Chinese patent document CN200820087255.6 discloses: an assembled steel bar truss template. The patent document discloses a structure capable of disassembling a steel bar truss construction bottom die, but the structure is stored in actual use, the cooperation of a connecting fastener and a connecting bolt is time-consuming, and meanwhile, the problems of more small parts, complex field installation and the like are caused.
Disclosure of utility model
Aiming at the defects in the prior art, the utility model provides the steel bar truss structure which is simple to operate, saves materials, is convenient to install and is convenient to detach the bottom die.
In order to achieve the aim of the utility model, the utility model adopts the following technical scheme:
The steel bar truss structure comprises a plurality of upper chord tendons which are distributed in parallel, wherein two lower chord tendons are arranged below the horizontal position of each upper chord tendon; the upper chord rib is connected with the lower chord rib through the web rib, and the lower chord rib is connected with the bottom die, and is characterized in that: the lower chord rib is connected with a connecting part, and the lower part of the connecting part is connected with the bottom die.
Further, the upper chord tendons are connected into a net rack through distribution tendons.
Further, the connecting part is tubular and is connected with the bottom die through a screw.
Further, the web bars are alternately connected with the upper chord bars and the lower chord bars.
Further, the web bars are wavy, and the bending parts are alternately connected with the upper chord bars and the lower chord bars.
Further, the bending part of the web rib extends out of the upper chord rib and the lower chord rib.
Compared with the prior art, the utility model has the following advantages:
1. the bottom die can be directly fixed by using screws or air nails through the connecting parts, so that the bottom die is very convenient to assemble and disassemble;
2. The connecting part is hollow, so that on one hand, the autogenous strength of the connecting part is ensured, and the bottom die is smoother after being connected;
3. The web member is wave, and the kink of web member stretches out last chord muscle and lower chord muscle simultaneously, makes web member and each junction of last chord muscle and lower chord muscle, has two at least tie points, has guaranteed structural strength.

Detailed Description
The following description of the embodiments of the present utility model is provided to facilitate understanding of the present utility model by those skilled in the art, but it should be understood that the present utility model is not limited to the scope of the embodiments, and all the utility models which make use of the inventive concept are protected by the spirit and scope of the present utility model as defined and defined in the appended claims to those skilled in the art.
Example 1
As shown in fig. 1 and 2, the steel bar truss structure with the bottom die convenient to detach comprises a plurality of upper chord tendons 101 which are distributed in parallel, and the number of the upper chord tendons 101 is more distributed according to the design size of each steel bar truss. Two lower chord ribs 102 are arranged below the horizontal position of each upper chord rib 101, and one upper chord rib 101 and two lower chord ribs 102 form a triangle when seen from the side.
The upper chord tendons 101 are connected to the adjacent lower chord tendons 102 by web tendons 103. The web ribs 103 ensure a stable structure between the upper chord rib 101 and the lower chord rib 102.
The lower chord rib 102 is connected with a connecting part 4, and the bottom die 3 is connected below the connecting part 4.
In the implementation process of the technical scheme of the application, the connecting part 4 can be of a strip-shaped or flat plate-shaped structure and is fixedly connected to the lower chord rib 102. The bottom die 3 and the connecting part 4 are directly fixed by screws or air nails when the bottom die 3 is installed.
Example 2
In this embodiment, the upper chord ribs 101 are vertically connected with distribution ribs 201, and the upper chord ribs 101 are connected into a whole net rack through the distribution ribs 201.
Example 3
In the present embodiment, the connecting portion 4 is tubular and is connected to the bottom die 3 by a screw. The tubular structure promotes the rigidity of connecting portion 4 under the condition that does not increase the dead weight on the one hand, and on the other hand is connected the back with die block 3, and screw or gas nail can not wrap up after cement pouring, makes things convenient for the later stage drawing of patterns.
In the implementation process of the technical scheme of the application, the cross section of the connecting part 4 can be rectangular, circular, trapezoid and the like. In actual use, the rectangle is convenient to process, and the bottom is flat and connected with the bottom die 3, so that more is adopted.
Example 4
In this embodiment, the web members 103 are in a wave shape, the web members 103 are alternately connected with the upper chord rib 101 and the lower chord rib 102, and the bending parts of the web members 103 are alternately connected with the upper chord rib 101 and the lower chord rib 102.
In the implementation process of the technical scheme of the application, the bending part of the web rib 103 extends out or is higher than the upper chord rib 101 and the lower chord rib 102, so that the technical scheme of the application has two welding points and is more stable compared with the traditional method that the bending part is directly connected with the upper chord rib 101 or the lower chord rib 102 by single-point welding during processing and welding.
