The utility model has the advantages of that: it can save a second processing before anchoring; it has good adaptability at the installation spot; it can at least save materials equal to anchoring groove to arrange it in the edge beams; it can connect well and prevent loosing and falling off; the edge beams can satisfy the needs of industrial quantitative production.
Description
Technical field
The utility model relates to a kind of anchoring type expansion gap device that improves structure, is used for for example covering and protective action at the shrinkage joint on railway, light rail, the highway bridge reserving in traffic infrastructure, belongs to means of transportation guard technology field.
Background technology
The structure of anchoring type expansion gap device is that industry is known, comprises the side bar of a pair of sealing both sides, shrinkage joint that are used to be set to reservation and is used for that a pair of side bar is anchored at the anchoring mechanism of sealing both sides, shrinkage joint and is bound up on the buffer zone that being used between a pair of side bar cover sealing and play protective action.Traditional anchorage style that is used for side bar is anchored in the shrinkage joint sealing mainly adopts welding or spiral marking connection.Welding is real to be caused thermal stress and tissue inter-variable easily, and has individual difference for fusion connects, and the welding position easily lost efficacy under long-term alternating stresses; Spiral marking connection then need process on side bar and be used for for the anchor bolt of anchoring mechanism or the anchoring screwed hole of title anchor rod screw-in, yet in order to process these anchor holes, just expose to have and followingly be not: the one, the processing of anchor hole is belonged to secondary operations, because it is to be the follow-up property processing done of reply actual installation after finishing in that side bar is processed in advance, must drop into manpower once more and enable corresponding apparatus and process the screw thread anchor hole, so can improve the product cost and the amount of labour used; The 2nd, the spacing of anchor hole, distributing does not have flexibility, can't regulate at random in the erecting bed, uses the situations such as distribution of the on-the-spot pre-buried muscle of reply, and if in the erecting bed side bar is processed anchor hole, then be subject to the factor restriction of equipment, power supply and so on; The 3rd, establish anchor hole between on the side bar and also can cause waste material; The 4th, operations such as the boring of processing anchor hole, tapping belong to the poor efficiency operation on side bar, are unfavorable for large-scale production.Therefore, above mentionedly anchoring mechanism and side bar are connect the welding, the spiral marking connection mode that are adopted all there is corresponding disadvantage to some extent.
Summary of the invention
The novel task of this use is to provide a kind of need not that side bar is carried out the anchoring type expansion gap device that but compliance secondary operations, the erecting bed is good and desirable, the anti-loose effect excellence of bond strength economical with materials, can satisfy the improvement structure of industrialization volume production requirement.
Task of the present utility model is finished like this, a kind of anchoring type expansion gap device that improves structure, it comprises that the side bar 1 of a pair of sealing both sides, shrinkage joint that are used to be set to reservation and at least one group are used for the anchoring mechanism 2 of the described a pair of side bar 1 of anchoring respectively and are bound up on the buffer zone 3 that being used between a pair of side bar 1 cover sealing and play protective action, be concaved with to entire body an anchoring type groove 11 on the described side bar 1, described anchoring mechanism 2 is in described anchoring type groove 11 positions and side bar 1 anchoring.
One side of side bar 1 described in the utility model is concaved with the buffer zone embedding slot 12 that is used to set described buffer zone 3.
Be formed with a through hole 13 that helps economical with materials on the side bar 1 described in the utility model.
The surface of side bar 1 described in the utility model constitutes anti-skidding bead 14.
Anchoring type groove 11 described in the utility model is formed on the side bar 1 obliquely.
The utility model directly constitutes anchoring type groove 11 on side bar 1, therefore can save the secondary operations before anchoring; Be formed on the side bar 1 because anchoring type groove 11 is entire body ground, so have good compliance, for example position that avertable embedded bar hindered in the erecting bed; Anchoring type groove 11 is found expression on the side bar 1, can save material at least corresponding to anchoring type groove 11 degree; After the groove inner nut 211 of the crab-bolt 21 of anchoring mechanism 2 placed anchoring type groove 11, the rotation of groove inner nut 211 and to move axially all be restricted was so have excellent connection and loosen and take off effect; Side bar 1 can satisfy industrialization volume production condition.
Description of drawings
Fig. 1 is an example structure figure of the present utility model.
Fig. 2 is the stereogram of side bar 1.
The specific embodiment
Please,, touch agent system by aluminium extruded with aluminum material processing side bar 1 in conjunction with Fig. 1, Fig. 2; Also can obtain side bar 1 by rolling mode by other metal material, when processing side bar 1, the anchoring type groove 11 on it, buffer zone embedding slot 12, through hole 13, anti-skidding bead 14 are integrally formed thereupon.Also illustrated both sides with buffer zone 3 to be embedded in the situation on the buffer zone embedding slot 12 respectively among Fig. 1, the material of buffer zone 3 is a rubber, by it shrinkage joint sealing between a pair of side bar 1 is covered, and prevents that rainwater etc. from entering and attacking the shrinkage joint.The anchoring type groove 11 that is formed on a pair of side bar 1 tilts, so can form splay supporting relation each other when one group of anchoring mechanism 2 after anchoring type groove 11 positions are anchored, very helps improving and the basic effect that combines.
The crab-bolt 21 of anchoring mechanism 2 is anchored at anchoring type groove 11 positions and side bar 1 by the inside and outside nut 211,212 of groove, groove inner nut 211 laterally is placed in the anchoring type groove 11, and matching with groove outer nut 212, to merge according to needing shimming 213 to make the upper end of bolt 21 be that the crab-bolt head is fixed.As crab-bolt 21, various corresponding variations are arranged unavoidably, and even the inside and outside nut 211,212 of groove also can have different variations, no matter but which kind of variation, as long as the anchoring type groove 11 of the utility model formed thereby on side bar 1 is used for taking on being provided with of task with the mutually solid similar fasteners of crab-bolt 21, so all should think within scope disclosed in the utility model, in view of the above, the restriction that is not also illustrated for the concrete shape of anchoring type groove 11.
Show that by Fig. 1 groove inner nut 211 both can be subjected to rotation tube bank in anchoring type groove 11, can be subjected to moving axially restriction again, can not occur and crab-bolt 21 between the phenomenon that gets loose.In addition, at the construction field (site), the distribution distance between each crab-bolt 21 can for example can be tackled the distribution scenario of on-the-spot embedded bar according to need adjusting, even crab-bolt 211 can also instantaneously changing or remodeled.
