Abstract
The utility model discloses an assembled box steel construction utility tunnel's axial connection structure, including corrugated steel plate, corrugated steel plate in the clod wash course of working, inwards or outwards bend in corrugated steel plate's crest or trough department, form the straight flange, regard as the sealed face of connection with this straight flange, the sealed face of connection on be provided with the bolt hole, when the piping lane of constituteing by corrugated steel plate saved and saved axial connection between, butt joint the sealed face of connection of corrugated steel plate and fix. The sealing surface between the pipeline sections of the utility model is integrally made by the corrugated steel plate through the folding edge, and the sealing performance is good; no welding seam exists between the pipeline sections, so that welding deformation is avoided, the material cost and the labor cost of welding are saved, and the construction process is simple; after the welding seam is cancelled, the first sealing surface can not be torn at the corner even if the first sealing surface deforms due to the action of the fastening force of the bolt in the connecting process; the accumulation of zinc is not easy.
Description
Technical Field
The utility model relates to an axial connection structure especially relates to an assembled box steel construction utility tunnel's axial connection structure.
Background
The applicant is dedicated to research and application of an assembly type box-type comprehensive pipe gallery, the applied steel structure comprehensive pipe gallery is made of corrugated steel plate wall plates which are arched outwards, the sections (namely, the sections in the axial direction) are connected by welding with the axial end parts of the corrugated steel plates by using angle steel or other section steel as flanges, and two flange surfaces of the angle steel are used as a first sealing surface and a second sealing surface for double sealing. However, in the actual production and construction process, the connection has the following problems: the welding deformation of the angle steel seriously affects the sealing effect; automatic welding (the angle steel needs to be rolled, the radian after rolling is difficult to be consistent with the camber of a corrugated plate of an outer arch, and the height difference exists), and the manual welding is difficult and labor-consuming; the welding seam bears bending moment and is easy to crack; zinc tends to accumulate during hot galvanizing.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a sealed effectual, the simple axial connection structure of assembled box steel construction utility tunnel of construction process.
The technical scheme is as follows: the utility model discloses a corrugated steel plate, corrugated steel plate in the clod wash course of working, bend in corrugated steel plate's crest or trough department, form the straight flange, regard as the connection sealing face with this straight flange, the connection sealing face on be provided with the bolt hole, when the pipe gallery of constituteing by corrugated steel plate saved and saved the axial between being connected, butt joint the sealed face of connection of corrugated steel plate and fix.
The side face of the connecting sealing face is provided with an angle steel, the angle steel is connected with the corrugated steel plate through bolts, and therefore the connecting sealing face is guaranteed not to deform in a plane in the bolt tightening process and the sealing effect is not affected.
The angle steel is parallel to the planar top of piping lane axial lead and is equipped with the clamp plate, the clamp plate pass through the bolt and be connected with the angle steel, increased sealing performance.
And a gasket is arranged between the connecting sealing surfaces and is connected with the connecting sealing surfaces and the angle steel, so that the sealing performance is improved.
The bending mode of the connecting sealing surface adopts inward or outward bending.
The working principle is as follows: in the corrugated steel plate cold-bending course of working, bend its crest or trough, form and connect sealed face, set up the bolt hole that the axial connection used on this connection sealed face, when two sections pipe racks carry out the axial connection, tighten up the in-process at the bolt and can not appear plane deformation in order to guarantee to connect sealed face, influence sealed effect, can set up an angle steel of strengthening the usefulness in the inboard of connecting sealed face, do not weld between angle steel and the corrugated steel plate, but when being connected between the festival of pipe rack and festival, compress tightly together through bolted connection. The plane of angle steel, the plane that is on a parallel with pipe gallery axial lead can form the second through clamp plate and the gasket of connecting between the sealed face, increases sealing performance.
Has the advantages that: the sealing surface between the pipeline sections of the utility model is integrally made by the corrugated steel plate through the folding edge, and the sealing performance is good; no welding seam exists between the pipeline sections, so that welding deformation is avoided, the material cost and the labor cost of welding are saved, and the construction process is simple; after the welding seam is cancelled, the first sealing surface can not be torn at the corner even if the first sealing surface deforms due to the action of the fastening force of the bolt in the connecting process; the accumulation of zinc is not easy.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses a corrugated steel plate 1, this corrugated steel plate 1 clod wash course of working, roll over an inside or outside straight flange in corrugated steel plate 1's crest or trough department, regard as the sealed face 2 of connection with this straight flange, and set up the bolt hole that the axial connection used on this sealed face 2 of connection. When the pipe gallery formed by the corrugated steel plate 1 is connected between the axial joint and the joint, the two pipe galleries are connected and sealed correspondingly in the sealing surface 2, and are fixedly connected into a whole through bolts.
In order to ensure that the connection sealing surface 2 cannot generate plane deformation in the bolt tightening process and influence the sealing effect, an angle steel 3 for reinforcement can be arranged on the inner side of the connection sealing surface 2, the angle steel 3 and the corrugated steel plate 1 are not welded, and the angle steel is connected with the sections of the pipe gallery through bolts and is compressed together. Angle steel 3 can be equipped with clamp plate 5 on a parallel with the planar top of piping lane axial lead, can set up gasket 4 between two connection seal face 2, forms the sealed face of second through clamp plate 5 and gasket 4, has increased the sealing performance of piping lane. The pressing plate 5 is provided with bolt holes, and the pressing plate 5 and the angle steels 3 on two sides of the bottom of the pressing plate are respectively connected and fixed through the pressing plate bolts. The gasket 4 is fixed by bolts connecting the sealing surfaces 2.
During the use, in corrugated steel plate 1 cold-bending course of working, bend its crest or trough, form and connect sealed face 2, set up the bolt hole that the axial connection used on this connection sealed face 2, when two sections pipe racks carry out the axial connection, tighten up the in-process in order to guarantee to connect sealed face 2 and can not appear the plane deformation at the bolt, influence sealed effect, can set up an angle steel 3 of strengthening usefulness in the inboard of connecting sealed face 2, do not weld between angle steel 3 and the corrugated steel plate 1, but when being connected between the festival of pipe rack and festival, compress tightly together through bolted connection. The plane of angle steel 3 that is on a parallel with pipe gallery axial lead can form the second through clamp plate 5 and the gasket of connecting between the sealed face 2 and seal the face, increases sealing performance.
