Bridge and highway expansion joint Sealing strip The microwave vulcanization process is used for one-time molding, with smooth and beautiful surface, good elasticity, compression resistance, weather aging resistance, ozone resistance, chemical resistance, wide temperature range (- 40 ℃~120 ℃) and other good properties. For products with different shapes, different materials, or cold resistance, heat resistance, body, and special performance requirements, Both can meet the needs of design and use. Main functions: insect proof, wind proof, light proof, anti-collision, sound proof, smoke proof and waterproof Manufacturing standard:

Rubber strip for bridge expansion joint: it is characterized by oil resistance, purity, ozone aging resistance, high strength, beautiful appearance, etc. It is the use of good materials for protective sealing, decoration and other products. I don't know whether careful friends have found it. However, there are more or less transverse joints on the bridge deck. Yes, this is the product I want to introduce - bridge expansion joints, Also called bridge expansion device. Expansion joint is an important part of bridge structure. Under the influence of factors such as temperature change, concrete shrinkage, live load, settlement and creep of bridge piers and abutments, the bridge span structure will deform, thus causing displacement of the beam end. In order to apply this displacement and maintain the smoothness of vehicles running on the bridge, transverse expansion joints must be set between the two ends of the bridge deck and between the beam end and the abutment back wall. Once the bridge expansion joint is damaged, it will lead to vehicle jumping, noise, water leakage, impact on driving safety and shorten the service life of the bridge
Road bridge expansion joint rubber strip The rubber strip of bridge expansion joint is not supposed to be installed for the expansion of the gap. The expansion of the bridge expansion joint depends on the width of the slot, which is why we often say that there are 80 such gaps. In fact, they are slot width gaps, because there are sliding bearings under the bridge where the bridge expansion joint is installed, which can facilitate expansion. The main function of the bridge expansion joint adhesive strip is waterproof and dust-proof, in order to prevent sundries from entering the gap and affecting the expansion. As for the installation of the rubber strip, it can be said that it is very simple. First, insert one end into one end of the profile steel of various holes, and then stretch the other end. When installing the profile steel of the other end, I have seen the bending tool used to install the inner tube of the bicycle. The sealant strip in the bridge expansion joint uses the rubber's air tightness and water expansion to effectively prevent rainwater leakage, protect the normal function of the bridge expansion joint and the road and avoid damage. The sealing strip can not only resist tension, but also carry out lateral and vertical displacement
