Abstract
The invention discloses a stable element for a seamless elastomer extension device. The stable element comprises an inner rod and an outer cylinder connected with the inner rod in a sleeving manner, wherein a steel spring pushing against the end part of the outer cylinder is sleeved at one end of the inner rod, which is exposed out of the outer cylinder; the end part of the inner rod is in threaded connection with a compression nut; a gasket is arranged between the compression nut and the steel spring; the other end of the outer cylinder is a closed end; a corrugated sleeve sleeved on the outer cylinder and the steel spring is arranged between the closed end and the gasket so as to separate the inner rod, the outer cylinder and the steel spring from the outside. The stable element has constraint and extension functions and can be completely placed into a groove of the seamless elastomer extension device without the operation of welding or bolting; moving parts are not in contact with an elastomer material, so that adhesive bonding is avoided; the mounting procedure is simplified greatly and the mounting time is saved.
Description
Technical field
The present invention relates to traffic and technical field of buildings, particularly a kind of stable element for gapless elastic body stretching device.
Background technology
Gapless elastic body stretching device is to fill seam district, whole shrinkage joint with elastomeric material, and what both guaranteed to drive a vehicle is steadily comfortable, can satisfy the needs of displacement structure again with the elastic deformation of self.Because the width of the elastomeric material of filling in the gapless shrinkage joint and thickness is bigger, producing than big displacement quantity, especially during pressurized, the phenomenon that arches upward vertically unstability occurring.Therefore, be provided with stable element in the gapless elastic body stretching device than big displacement quantity, be used for the arching upward of constraint material, do not influence the normal flexible of whole device simultaneously.
Common stable element is made of axle and sleeve; its two ends need be fixed on the structural members such as angle steel of gapless elastic body stretching device by welding or bolt during installation; the part that needs earlier axle to be exposed sleeve when building elastomeric material protects; avoid axle and to water material feeding bonding and influence is stablized original paper in axial activity, increased the complexity of constructing.And also have a problem to be exactly, and whole stable original paper is when bearing vertical load, and the stress at end welding or bolt place is bigger, is easy to generate destruction.
Summary of the invention
Goal of the invention of the present invention is: at the problem of above-mentioned existence, provide a kind of stable element for gapless elastic body stretching device.
The technical solution used in the present invention is such: a kind of stable element for gapless elastic body stretching device, in comprising bar and with the urceolus of its socket, the part that bar one end exposes urceolus in described is with the steel spring that abuts to the urceolus end and is connected with clamp nut in this end thread of interior bar, be provided with pad between clamp nut and spring, the described urceolus other end is closed end, between closed end and pad, be provided with the corrugated bushing that is enclosed within urceolus and steel spring outside, interior bar, urceolus, steel spring and outside are separated.
In sum, owing to adopted technique scheme, the invention has the beneficial effects as follows: when having constraint, Telescopic, and can whole insert in the groove of gapless elastic body stretching device, and do not need welding or bolt to fix; Movable part does not come in contact with elastomeric material, avoids bonding, has simplified erection procedure greatly, has saved the set-up time.

Mark among the figure: 1 is interior bar, and 2 is urceolus, and 3 is steel spring, 4 is clamp nut, and 5 is pad, and 6 is corrugated bushing, 7 is the macromolecular elastomer packing material, and 8 is the base layer of concrete, and 9 is gusset, 10 is set bolt, 11 is waterproof adhesive tape, and 12 is stable element, and 13 is cover plate, 14 is supercrust, and 15 is roadbed.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is done detailed explanation.
Most preferred embodiment: as shown in Figure 1, a kind of stable element for gapless elastic body stretching device, in comprising bar 1 and with the urceolus 2 of its socket, the part that bar 1 one ends expose urceolus 2 in described is with the steel spring 3 that abuts to urceolus 2 ends and is connected with clamp nut 4 in interior bar 1 this end thread, 3 of clamp nut 4 and steel springs are provided with pad 5, described urceolus 2 other ends are closed end, between closed end and pad 5, be provided with the corrugated bushing 6 that is enclosed within urceolus 2 and steel spring 3 outsides, interior bar 1, urceolus 2, steel spring 3 are separated with the outside.
The present invention is used for the structure of gapless elastic body stretching device and describes:
In Fig. 2, with called after stable element 12 of the present invention.
Described stable element 12 is installed in the gapless elastic body stretching device, this gapless elastic body stretching device comprises the roadbed 15 of body with seam and covers supercrust 14 on it, be stamped cover plate 13 on the seam body of described roadbed 15, arrange in the hole of the roadbed 15 at seam body two ends base concrete layer 8 and respectively a pre-buried set bolt 10 imbed in the roadbed 15 after running through base concrete layer 8 from top to bottom always, be with gusset 9 on the described set bolt 10 and fix with nut, described stable element 12 just is arranged between the gusset 9 at seam body two ends of roadbed 15, the elastomer-filled material 7 of filled high polymer above base concrete layer 8 is until concordant with supercrust 14.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
