Abstract
The utility model discloses an extension rubber edge-block, belonging to a technical field of a gap extension connecting device for connecting two girder bodies or a girder and a bridge platform. The utility model is characterized in that the extension rubber edge-block are provided with a protruding block and a notching joint on two edges, a connecting screw of the edge-block is provided with a notching joint ring on the side wall and a rubber cap which is buckled on the screw is provided with a stiffener rib on the top portion and a protruding ring on the lateral side. The utility model solves the problem of the extension rubber edge-block, such as forming the gap because the edge-block can not be connected with each other and making the sewage water and the waste pass through the gap to the girder body which causes the easy deformation and has the advantages of simple structure and obvious effect.
Description
The utility model belongs between the beam body of bridge, the linkage technical field between beam body and the abutment, discloses a kind of rubber limit briquetting that is used for fixing the shrinkage joint specifically.
Between the beam body of railway or highway bridge, all be fixed with rubber fastening band in the shrinkage joint between beam body and the abutment, at present in case fluid stopping water enters the beam body.And the dual-side of waterstop is fixed by parallel rubber press.Owing to formed the slit between the rubber press,, worked the mischief to pontic so sewage and foul thereof are very easily invaded pontic from formed slit.And without any the connection measure, rubber press very easily is out of shape between the rubber press, does not have the effect of briquetting.
The purpose of this utility model just provides a kind of connection shrinkage joint rubber limit briquetting closely.
The technical scheme that realizes rubber limit, the shrinkage joint briquetting that the utility model proposed is: its front has the fixing threaded hole of several screw Capsules, one end of described rubber limit briquetting is at least one projection, and the other end is a groove corresponding with projection and can be meshing.
Be the bottom that described projection and groove are in rubber limit briquetting respectively in addition; One groove ring is arranged on the sidewall of described screw; Described connecting hole can be garden shape or ellipse garden shape; The side of described Capsule has bulge loop; The end face of described Capsule has reinforcing rib.
Rubber limit, the shrinkage joint briquetting that the utility model proposed is compared with prior art, have the following advantages: owing to be provided with projection and the groove that is used to connect at the two ends of rubber limit, shrinkage joint briquetting, the two butt joint makes between briquetting and the briquetting and closely is connected, and has avoided the appearance of seam; In addition because in the side of the fixing threaded hole of briquetting; an annular groove is arranged, and the side of the rubber cap of its screw fixing hole has corresponding convex ring, connects so rubber cap buckles into to be tightly connected behind the fixing hole; prevented the intrusion of sewage foul, played protective effect screw.
Be described further below in conjunction with the structure of accompanying drawing rubber limit, the shrinkage joint piece that the utility model proposed:
Fig. 1: be the structural representation of rubber limit, shrinkage joint briquetting;
Fig. 2: be the front view of limit briquetting shown in Figure 1;
Fig. 3: be the structural representation of limit briquetting rubber cap;
Fig. 4: be the front view of rubber cap shown in Figure 3.
Be the structure and the front schematic view of rubber limit, shrinkage joint briquetting as shown in Figure 1, 2.The bottom that this rubber limit, shrinkage joint briquetting is strip, an end has projection 1, and other end bottom be one with projection 1 corresponding groove 2, and projection and corresponding groove can be several, when the projection 1 of limit briquetting one end inserts in the groove 2 of another limit briquetting, make to form seamless link between the briquetting.Have several fixing threaded holes 3 in addition on rectangular briquetting, this fixing hole can be that garden shape also can be an ellipse garden shape as shown in the figure, and its medial surface is a groove ring 4.Be depicted as the screw Capsule structure chart that fixing hole 3 is sealed as Fig. 3,4, this screw Capsule is corresponding with fixing threaded hole 3, and its side is a bulge loop 5, in addition, reinforcing rib 6 is arranged at the top, and after Capsule buckled into fixing threaded hole, bulge loop 5 just in time snapped in and makes the fixing hole sealing in the annular recess 4.The projection that the utility model adopted, groove connected mode are connected as a single entity several limit briquettings, and are with the Capsule of bulge loop to make the fixing threaded hole sealing, have prevented that sewage, foul from immersing the generation that beam embodies elephant.
Claims (6)
