Abstract
The present invention discloses an expansion joint regulator element and an expansion joint regulator made thereof. The expansion joint regulator element is composed of an expansion back and expansion girders which are uniformly cast left and right in equal distance on one side of the expansion back, wherein the length of each expansion girder is equal, and the expansion girders are parallel mutually. The top plane and the bottom plane of the expansion back and the top surface and the bottom plane of each expansion girder are superposed. The expansion joint regulator is formed by relatively inserting the two identical elements mutually. The expansion joint regulator element of the present invention is formed in one piece by a casting method and has the advantages of simple technology, simplified structure, easy manufacture, low cost and convenient generalization and application. The two expansion elements of the expansion joint regulator are relatively inserted mutually, which avoids the resonance phenomenon caused by impact force produced in the running course of vehicles and efficiently enhances the service life of buildings of bridges, etc. Moreover, the present invention has the advantages of easy manufacture, easy construction, compact integral structure, firm structure and easy popularization and application and reaches the degree of being free from maintenance.
Description
Technical field
The present invention relates to the shrinkage joint regulator member used on the buildings such as a kind of bridge and the shrinkage joint adjuster of formation thereof.
Background technology
The shrinkage joint adjuster all has application on a lot of buildings, for bridge, the effect of shrinkage joint adjuster is more obvious.The shrinkage joint adjuster can eliminate the joint of bridge place the slit, eliminate vehicle by the time impact that produces because of beating, help application life of ease driving and prolongation bridge.
" Chinese utility model patent communique " announced a kind of patent No. is ZL93219115, name is called the utility model patent of " alternate inlay type bridge extension seam ", the shrinkage joint of this patent is the equidistant diaphragm that is fixed with in two supported boxs, between two supported boxs, arranging extensible canopy, adjacent two opposing two ends of extensible canopy are fixed on the diaphragm of supported box, running roller is equipped with at another opposing two ends, running roller is inserted into respectively between the dividing plate of relative supported box, and straight joint in the going up that a top is narrow, the bottom is wide is arranged between every adjacent two extensible canopies.This technical scheme has reached driving and has increased steady, flexible effect flexibly, but this technical scheme need be pulled metalworking, constructs by the mode of welding, and globality is poor, and complex structure is made numerous rope, is easy to produce fault, and maintenance capacity is big, is unfavorable for applying.
Summary of the invention
The object of the present invention is to provide a kind of one-time formed shrinkage joint of forging type regulator member of passing through, a kind of shrinkage joint adjuster that is made of this expansion and cotraction regulator member is provided simultaneously.
For achieving the above object, technical program of the present invention lies in having adopted a kind of shrinkage joint regulator member, this shrinkage joint member is extended successively by plural element of construction and is formed by connecting, each element of construction constitutes at the extensible canopy of the equidistant even casting of bearing of trend by the flexible back of the body and flexible back, each extensible canopy equal in length, be parallel to each other, top, the baseplane of top, baseplane and each extensible canopy of the flexible back of the body coincide, and the cross section of each extensible canopy is top, wide " worker " font structure in bottom surface.
The width of described each extensible canopy is less than the size of space between the extensible canopy.
Evenly be fixed with the threaded connector that is used to connect pre-buried connecting rod on the back side, the outside of the described flexible back of the body, the flexible back of the body overhanging formation one supporting plate plane, bottom surface.
Simultaneously, technical program of the present invention also lies in adopting the shrinkage joint adjuster that utilizes above-mentioned shrinkage joint regulator member to constitute, this adjuster is made of inserting two groups of identical described members, every group of member extended successively by plural element of construction and is formed by connecting, each element of construction constitutes at the extensible canopy of the equidistant even casting of bearing of trend by the flexible back of the body and flexible back, be provided with the reservation notch between per two extensible canopies, each extensible canopy equal in length, be parallel to each other, the baseplane of the flexible back of the body overlaps with the baseplane of reserving notch, and the cross section of each extensible canopy is the top, " worker " font structure that the bottom surface is wide.
The width of described each extensible canopy is less than the size of space between the extensible canopy.
Evenly be fixed with the threaded connector that is used to connect pre-buried connecting rod on the back side, the outside of the described flexible back of the body, the flexible back of the body overhanging formation one supporting plate plane, bottom surface.
In each extensible canopy slit each other, be filled with bipeltate.
Because shrinkage joint of the present invention regulator member is by the mode one-shot forming of casting, technology is simple, and designs simplification is easily manufactured, and is with low cost, easy to utilize.The width of each extensible canopy is less than the size of space between the extensible canopy, and extensible canopy can stretch along with the difference of stroke size like this; After extensible canopy adopts " worker " shaped sections, improved the mechanical property of product effectively, alleviated consumable quantity and product weight, both can reduce cost, can alleviate again building such as bridge from heavy load, thereby prolong application life of building.On bearing of trend, interconnect, can reduce the difficulty of casting, and help on-the-spot transportation and construction.The shrinkage joint adjuster that utilizes shrinkage joint of the present invention regulator member to be assembled into, because telescoping member plugs each other, the covibration that the impact force of having avoided being produced in the vehicle ' process causes, strengthened the application life of buildings such as bridge effectively, this shrinkage joint adjuster is easily manufactured, easy construction, compact overall structure, structure has firmly reached the degree that avoids keeping in repair, and applies easily.The present invention behind the filling-foam rubber, had both guaranteed normal Telescopic in the extensible canopy slit, avoided leaking in deposition foreign material and the beam, had reduced maintenance capacity and operation cost again.
