Abstract

The invention relates to a slidable lap joint structure of a spliced corrugated plate culvert. Increase of the lap joint length of corrugated steel plates or the number of bolts easily causes faulting of slab ends in construction and is not beneficial to misplaced splicing construction, and fastening connection cannot adapt to the large deformation demand. According to the slidable lap joint structure, a kidney-shaped hole is formed in one end of each corrugated plate, a round hole is formed in the other end of the each corrugated plate, and the kidney-shaped holes and the round holes of the adjacent corrugated plates are mutually in lap joint and are connected through high-strength bolts. The high-strength bolts are provided with upper gaskets and lower gaskets respectively on the upper side and the lower side of the spliced position of the adjacent corrugated plates and are fixed through nuts. Multiple balls or sliding plates are arranged on the faces, in contact with the lower gaskets, of the corrugated plates. The corrugated plates of the slidable lap joint structure are connected through lap joint of the kidney-shaped holes and the round holes in a bolted mode, a certain moving displacement amount is achieved, the load and deformation demands are met, the balls or the sliding plates are arranged between the movable corrugated plates and the gaskets, the friction force in the sliding process can be decreased, stress concentration can be prevented, and sliding can be easier.

Description

The slidably bridging arrangement that pin-connected panel corrugated sheet is contained
Technical field
The invention belongs to transport development technical field, be specifically related to the slidably bridging arrangement that a kind of pin-connected panel corrugated sheet is contained.
Background technology
Infrastructure construction is in recent years greatly developed, frequent needs are with a varied topography, bad environments, the mountain area building highway of ravines and guillies criss-cross, in order to reach the address routing indicator of speedway, one of high-fill roadbed common type becoming High Grade Highway in Mountain Area, the plain plate of same thickness is rolled into the corrugated steel with bellows-shaped, its moment of inertia significantly increases, the ability of opposing load significantly strengthens, so steel corrugated sheet culvert can resist the dead load of the soil body and the dynamic load of driving better, ensure the safety after being open to traffic, its safety factor increases greatly, the application of corrugated sheet culvert in engineering is more and more extensive.
Because the geological condition of culvert substrate is comparatively complicated, in work progress, usually can cause corrugated steel tube after backfill, even just produce the distortion exceeding permissible value in backfilling process; Meanwhile, because there is link bolt hole individual layer corrugated steel end, when corrugated steel plate is spliced to form tube coupling, there is the stressed concentration problem in corrugated steel end, may cause the potential safety hazard of local yielding in the armor plate strength decay of stitching position; In addition, high roadbed culvert need bear larger soil pressure, if the excessive deflection exceeding it and can bear of soil pressure, the cracking of culvert also can be caused even to destroy.
In order to solve the problem, generally can lengthen steel plate lap length, increasing bolt quantity, or can thicken the steel plate wall of corrugated steel culvert or add backing plate, so not only increase financial cost, and easily produce faulting of slab ends, be unfavorable for the assembling construction that misplaces.
Summary of the invention
The object of this invention is to provide the slidably bridging arrangement that a kind of pin-connected panel corrugated sheet is contained, not only ensure the intensity of corrugated sheet overlapping part, also make corrugated sheet overlapping part that reliable sliding function is set, meet pin-connected panel corrugated sheet and contain the movable displacement demand in construction and use procedure.
The technical solution adopted in the present invention is:
The slidably bridging arrangement that pin-connected panel corrugated sheet is contained, is characterized in that:
Arrange waist-shaped hole in one end of corrugated sheet, the other end arranges circular hole, and waist-shaped hole and the circular hole of adjacent corrugated sheet overlap mutually, are connected by high-strength bolt;
High-strength bolt is respectively arranged with upper gasket and lower gasket in the both sides up and down of adjacent corrugated plate stitching portion, and is fixed by nut.
The surface that upper gasket and lower gasket contact with corrugated sheet is set to the radian identical with corrugated sheet.
The contact surface of corrugated sheet and lower gasket is provided with multiple ball, and ball is embedded in the groove that lower gasket is arranged.
The contact surface of corrugated sheet and lower gasket is provided with slide plate, and slide plate is embedded in the groove that lower gasket is arranged.
Slide plate is tetrafluoro plate, modified Teflon plate or ultra-high molecular weight polyethylene board.
The contact surface of adjacent corrugated sheet overlap joint arranges antifriction material.
The present invention has the following advantages:
1, adjacent corrugated sheet adopts waist-shaped hole and circular hole mutually to overlap rear bolt, can realize certain movable displacement, thus meets the needs of load and distortion.
2, corrugated sheet such as to arrange at the packing ring with radians such as corrugated sheets between being connected with high-strength bolt, can play the function of reinforcement, avoid the stressed concentration problem in corrugated steel end to overlapping part.
3, ball or slide plate are set between movable corrugated sheet and packing ring, the frictional force in sliding process can be reduced, prevent stress from concentrating, make slip easier.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be described in detail.
The present invention relates to the slidably bridging arrangement that a kind of pin-connected panel corrugated sheet is contained.Arrange waist-shaped hole in one end of corrugated sheet, the other end arranges circular hole, and waist-shaped hole and the circular hole of adjacent corrugated sheet overlap mutually, are connected by high-strength bolt 4.High-strength bolt 4 is respectively arranged with upper gasket 6 and lower gasket 3 in the both sides up and down of adjacent corrugated plate stitching portion, is all fixed by nut 5.The surface that upper gasket 6 and lower gasket 3 contact with corrugated sheet is set to the radian identical with corrugated sheet.The contact surface of adjacent corrugated sheet overlap joint arranges antifriction material, as steel backing antifriction material, metal-plastic Anti-friction Composite Material, metal-solids sliding agent Anti-friction Composite Material etc.
Embodiment 1:
See Fig. 1-3, the contact surface of corrugated sheet and lower gasket 3 can arrange multiple ball 7, and ball 7 is embedded in the groove that lower gasket 3 is arranged.The present invention can realize relative displacement in waist-shaped hole, and the ball 7 between corrugated sheet with lower gasket 3 avoids corrugated sheet and directly contacts with lower gasket 3, and sliding friction is conjugated rolling friction, is conducive to sliding.
