Description
Technical Field
The utility model belongs to construction electrical engineering field, concretely relates to strong and weak current crane span structure tee bend, especially a bottom opening bridge height difference tee bend.
Background
It is known that in the construction of strong and weak cables and wires, bridges are generally used as carriers. Often conflict with other professional pipelines in space in the crane span structure installation, because of the crane span structure possesses strong, the light characteristics of plasticity, under the pipeline collision condition, often select the crane span structure to dodge other pipelines, lead to the crane span structure to take place a large amount of bends. The main road bridge frame is required to be provided with branch road bridge frames in general, when other pipelines exist at the same height with the main road bridge frame and the other pipelines and the main road bridge frame do not have enough horizontal distance, only one upward turning bend and one downward turning bend can be made on the main road bridge frame, the installation can be realized only by arranging a horizontal tee between the two turning bends, the installation method occupies a large space, and the installation process is relatively complicated. And if the method is adopted when a plurality of parallel bridges are branched at the same position, because the bent horizontal tee joint section of the main road bridge exists, a plurality of branched branch bridges can be installed only by being spaced apart by a certain distance and cannot be arranged closely.
Especially, the pipelines are increasingly complex, the compressor is mounted in the space as much as possible in order to pursue the space for building, and it is important to reduce the time and space for mounting the bridge frame under the condition that the labor cost is increased continuously.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a bottom opening bridge height difference tee bend that uses when having the difference in height.
The technical scheme of the utility model outlines as follows:
a bottom opening bridge height difference tee joint comprises an upper groove 1 with a U-shaped section, wherein the upper groove comprises an upper groove bottom plate 2 and side plates 3, hems 4 are arranged at the upper ends of the side plates, two end parts of each side plate are respectively provided with four oval connecting holes 13, a rectangular hole 5 is arranged in the middle of the upper groove bottom plate, four sides of the rectangular hole 5 are respectively fixedly connected with the upper end of a cylinder formed by connecting an isosceles trapezoid plate 6, a parallelogram plate 7, a second isosceles trapezoid plate 9 and a second parallelogram plate 15, the lower end of the isosceles trapezoid plate 6 is connected with the upper end of a rear rectangular plate 8, the lower end edge of the parallelogram plate 7 is connected with part of the upper end of a right-angle trapezoid plate 10, the lower end of the second parallelogram plate 15 is connected with part of the upper end of a second right-angle trapezoid plate 16, the lower end of the rear rectangular plate 8 is connected with the rear end of a bottom plate 14, the other part of the upper end of the right-angle trapezoid plate 10 and the other part, right trapezoid board 10 and second right trapezoid board 16 are provided with four oval connecting holes 12 respectively, and the both ends of back rectangular plate 8 are connected with right trapezoid board 10 and the 16 hypotenuses of second right trapezoid board respectively, and the both sides limit of bottom plate 14 is connected with right trapezoid board 10 and the 16 lower extremes of second right trapezoid board respectively.
The included angle between the two side edges of the isosceles trapezoid plate 6 and the upper edge (i.e. the lower bottom of the isosceles trapezoid) is between 30 ° and 90 °.
The utility model has the advantages that:
the utility model solves the problems that when a branch is arranged on a bridge frame at the dense part of a pipeline, a main line and a branch line are connected through a three-way junction with an opening at the bottom, thereby avoiding the use of excessive connecting pieces and abnormal-shaped pieces, increasing the stability of the bridge frame, reducing the construction procedures and saving the material and labor force of the bridge frame; and the horizontal distance between the main road bridge frame and other pipelines at the same height can be infinitely close under the condition of meeting the standard, so that the occupied space of the bridge frame is reduced, and meanwhile, the reasonability and the attractiveness of the comprehensive arrangement of the pipelines are ensured.
