Abstract

The utility model relates to the pipe gallery structure field, in particular to a novel long-span pipe bridge structure. The novel long-span pipe bridge structure comprises a first pipe bridge, a second pipe bridge, an end portion rigid frame and a support. The novel long-span pipe bridge structure is characterized in that one end of the first pipe bridge is fixedly connected with one side of the end portion rigid frame. One end of the second pipe bridge is connected with the other side of the end portion rigid frame to form a connecting node through a bolt at the time of field assembly. Positioned strength-bearing brackets are arranged at the top ends of the second pipe bridge and the support. Compared with the prior art, the novel long-span pipe bridge structure has the advantages that the multi-span continuous truss structure is used for enabling the several sectional bridge frames to be connected into a unity so as to eliminate eccentric distance load of the support, improve bearing capacity of the bridge frames, decrease effectively deformations of the bridge frame and improve the manufacture quality of the pipe bridge.

Description

A kind of New Types of Super-span Pipe Bridges structure

Technical field

The utility model relates to the Pipe rack field, relates in particular to a kind of New Types of Super-span Pipe Bridges structure.

Background technology

Piping lane is the bridge that connects each equipment, and is general for laying the various pipelines such as process pipelines, utility line, instrument pipeline and cable on it.See accompanying drawing 3, the tradition piping lane is connected to form by the multistage pipe bridge, consist of the single span freely supported structure, two adjacent pipe bridges one (1) and the end rigid frame one (3) separately of using respectively of pipe bridge two (2) are connected with support (5) with end rigid frame two (4), general two pipe bridges weld rear and all there is eccentric throw in carriage center, and when particularly support both sides pipe bridge was uneven in length, then support can be subject to an eccentric force, must increase thus support cross section and bracket basis size, the distortion of piping lane is strengthened.

Summary of the invention

The purpose of this utility model provides a kind of New Types of Super-span Pipe Bridges structure, overcomes the deficiencies in the prior art, adopts multispan continuous trusse structure, and a plurality of crane span structures are connected, and improves the bearing capacity of crane span structure, and reduces the crane span structure distortion.

For solving the problems of the technologies described above, the technical solution of the utility model is:

A kind of New Types of Super-span Pipe Bridges structure, comprise pipe bridge one, pipe bridge two, end rigid frame and support, one end of pipe bridge one is fixedly connected with a side of end rigid frame, is connected to form continuous nodes during the opposite side Assembling of an end of pipe bridge two by bolt and end rigid frame.

Described pipe bridge two and cantilever tip are provided with the load rest of location.

Compared with prior art, the beneficial effects of the utility model are: by adopting multispan continuous trusse structure, make a plurality of segmentation crane span structures be linked to be an integral body, eliminated support eccentric throw load, improved the bearing capacity of crane span structure, and effectively reduced the distortion of crane span structure, improved pipe bridge and made quality.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:

See Fig. 1, Fig. 2, it is a kind of New Types of Super-span Pipe Bridges structure of the utility model example structure schematic diagram, comprise pipe bridge 1, pipe bridge 22, end rigid frame 8 and support 5, before dispatching from the factory, one end of pipe bridge 1 is fixedly connected with a side of end rigid frame 8, during Assembling, an end of pipe bridge 22 and the opposite side of end rigid frame 8 consist of continuous nodes, and the end plate 6 that winds up of pipe bridge 27 is connected with the opposite side of end rigid frame 8 respectively by bolt 9 with lower edge end plate 7.

In order to satisfy the positioning requirements of pipe bridge 22, pipe bridge 22 and support 5 tops are provided with the load rest 10 of location, transmit vertical force by load rest 10, the end plate 6 that winds up links to each other with end rigid frame 8 by bolt 9 with lower edge end plate 7 and transmits horizontal force, adjacent two crane span structures share an end rigid frame, a plurality of crane span structures are connected, become the multispan continuous trusse, effectively eliminated support eccentric throw load, improve the bearing capacity of crane span structure and reduced the crane span structure distortion, be particularly suitable for the making of Types of Super-span Pipe Bridges, save investment, improve speed of application.
