Abstract
The utility model relates to a tip bearing structure is contained to arch buckled plate. The tip of arch culvert supports and adopts directly and the concrete form of concrete foundation at present, has retrained its rotational degrees of freedom, and under the deformation and circumferential force effect of the left and right sides orientation that the pressure that bankets caused, here very easily produces stress concentration, is unfavorable for line pipe culvert hole safety. The utility model discloses the crest of buckled plate bottom or trough pass through connecting bolt and link to each other with the pin, and the pin below sets up the base, and the groove phase adaptation cooperation that sets up is gone up with concrete foundation to the base, the base is halfcylinder structure or spherical support structure, is provided with pre -buried steel sheet in concrete foundation's the recess, and the base is fixed in concrete foundation through pre -buried steel sheet. The utility model discloses can realize that the buckled plate articulates the support mode, have the load and rotate the function, better bearing because the banket deformation and the circumferential force of the left and right sides direction that pressure aroused to avoid stress concentration, improve the atress of buckled plate, increase of service life.
Description
Technical field
This utility model belongs to transport development technical field, is specifically related to a kind of arch corrugated plate and contains end support structure。
Background technology
Infrastructure construction in recent years is greatly developed, it is frequently necessary to the mountain area building highway at a varied topography, bad environments, ravines and guillies criss-cross, in order to reach the address routing indicator of highway, one of high-fill roadbed common type becoming High Grade Highway in Mountain Area, corrugated steel relatively flat plate the moment of inertia dramatically increases, the ability of opposing load is obviously enhanced, so Performance Test of Corrugated Steel Culvert can better against the dynamic load of the dead load of the soil body and driving, ensure the safety after being open to traffic, its safety coefficient is greatly increased, and the application in corrugated culvert engineering is more and more extensive。
Generally, when carrying out arch corrugated plate and containing design and mechanical property calculating, owing to barrel is longer, a root length beam can be regarded as, therefore vertically can intercept with unit length section along culvert longitudinal axis, process as plane strain problems。Considering displacement structure characteristic, its two ends adopt hinged constraint, retrain end displacement, release end rotational freedom。
But the end of arch culvert supports at present is adopt direct and concrete foundation consolidation form, constrain its rotational freedom, under the deformation and circumferential force effect of the left and right directions banketed caused by pressure, as easy as rolling off a log generation stress is concentrated herein, is unfavorable for stricture of vagina pipe culverts safety。
Summary of the invention
The purpose of this utility model is to provide a kind of arch corrugated plate and contains end support structure, can not only bear the circumferential force owing to banketing caused by pressure, and can adapt to banket the deformation of left and right directions that pressure causes by flexible rotating, it is achieved hinge function。。
The technical scheme that this utility model adopts is:
A kind of arch corrugated plate contains end support structure, it is characterised in that:
The crest of corrugated plating bottom or trough are connected with pin by connecting bolt, and pin is arranged below pedestal, and pedestal adapts with the groove arranged in concrete foundation and coordinates。
Pedestal is semicylinder structure；
Being provided with pre-embedded steel slab in the groove of concrete foundation, pre-embedded steel slab is the semi-cylindrical form groove with pedestal same radius, and the ball impression degree of depth of pre-embedded steel slab is less than the ball impression degree of depth of pedestal。
Pedestal is spherical bearing structure, including upper spherical plate and recessed ball plate；
Being provided with pre-embedded steel slab in the groove of concrete foundation, pedestal is fixed on concrete foundation by pre-embedded steel slab。
Pedestal is rubber support or pot bearing；
Being provided with pre-embedded steel slab in the groove of concrete foundation, pedestal is fixed on concrete foundation by pre-embedded steel slab。
Between concrete foundation and the pin of soil body side, sealing plate is set, sealing plate one end be embedded in concrete foundation, the other end and pedestal and corrugated plating are fixed。
This utility model has the advantage that
This utility model solves the rotational problems of corrugated culvert Support Position, corrugated plating hinged support mode can be realized, there is the dual-use function of load and rotation, can better bear the deformation due to the left and right directions caused by pressure that bankets and circumferential force, thus avoiding stress to concentrate, improve the stress of corrugated plating, increase the service life。

Detailed description of the invention
Below in conjunction with detailed description of the invention, this utility model is described in detail。
This utility model relates to a kind of arch corrugated plate culvert end support structure, and the crest of corrugated plating bottom or trough are connected with pin 2 by connecting bolt 3, and pin 2 is arranged below pedestal 4, and pedestal 4 adapts with the groove arranged in concrete foundation 5 and coordinates。Arranging sealing plate 7 between concrete foundation 5 and the pin 2 of soil body side, one end of sealing plate 7 is embedded in concrete foundation 5, and the other end is fixed with pedestal 4 and corrugated plating 1。
Embodiment 1:
Pedestal 4 is semicylinder structure。Being provided with pre-embedded steel slab 6 in the groove of concrete foundation 5, pre-embedded steel slab 6 is and the semi-cylindrical form groove of pedestal 4 same radius, and the ball impression degree of depth of pre-embedded steel slab 6 is less than the ball impression degree of depth of pedestal 4。
Embodiment 2:
Pedestal 4 is spherical bearing structure, including upper spherical plate and recessed ball plate。Being provided with pre-embedded steel slab 6 in the groove of concrete foundation 5, pedestal 4 is fixed on concrete foundation 5 by pre-embedded steel slab 6。
It addition, pedestal 4 also can adopt rubber support or pot bearing, same, the groove of concrete foundation 5 is provided with pre-embedded steel slab 6, pedestal 4 is fixed on concrete foundation 5 by pre-embedded steel slab 6。
