Hao-looking company of choice for bridge expansion joints, road bridge expansion joints prices, Baoji bridge expansion joints supplied by Hao-engineering rubber. We are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) located at: Hebei Hengshui specializes in: grid bearings, bridge expansion joints, water stop, bridge bearings, rubber bearings, ball bearing steel bridge expansion seam transmission bridge expansion joints J-75 multi-slotted transmission type bridge expansion is determined by the control arm, joystick and other ancillary pieces of composition. Joystick from the beams in through the web, and a cylindrical bearing where co shown in Figure 5-4. Mechanical movement bridge expansion joints transmission mechanism will be as follows: the beam embedded in the body of the cabinet led control arms, control arm forcing the lever rotates, joystick push to slide axially along the bridge beams, beams and prompting the lateral stringers parallel movement. Bridge expansion joints by Yan-shaped rubber seals rubber and stainless steel clamp bar and clip blocks. Side of the block is about to rubber bridge expansion joints with tooth pattern pressed into the inner recesses of the clip, clip a certain distance of the outer edge of the vertical sleeve with clip every block, the block with stainless steel bolt through the clamp, the clamp on the rubber strip stringers beneath the flange, as shown in Figure 5-5 bridge expansion joints that are generally applicable to a small stretch to close seams bridge types D60 type bridge expansion joints, it is necessary conditional on structural beam length is shorter, telescopic a small amount, it is also smaller birdie, while not worry about cracking or breakage of the bridge deck project. This seam is usually applied to the asphalt deck, and for concrete bridge deck should generally be used with caution. The main reason is the kind of bridge expansion joints seam construction features is the use of asphalt mixes telescopic nature instead of sawn reserved groove joint material, and when this mixture by a specialized company to carry out a special meet, it is difficult As a general material got, so only a small amount of use, while the situation before and after the bridge deck construction generally be selected according to the bridge. This bridge expansion joints on the following aspects have their special requirements, the mixed material should be waterproof seams, waterproof seams when a wind of material good, strong bond with the wall comb plate bridge expansion joints, can resist repeated scalable, can cope with the changes in considerable elongation and materials have resilience, waterproof seams materials are generally the best available room temperature, poured into the type of elastic joint material. According to foreign experience, as shown in its general nature. Waterproof seam construction materials must fully consider increasing their cohesiveness. Bridge expansion joints perpendicular to the sun's rays are most intense direct radiation in the summer and winter weakest, and are subject to atmospheric transparency. The structure of the solar radiation is absorbed in part by the outside of the reflective structure. Solar heat is absorbed to make the bridge structure to avoid temperature rises, and gradually transfer to the internal structure of the road bridge expansion joints price, bridge expansion joints are also part of the heat from the surrounding air due to structural wall between convection and radiation heat teach bad losses made . Convective heat exchange with the surface of the structure in addition to the custom increases. During the day, the structure of the heat from the outside into the net, bridge expansion joints so that the temperature rise of the bridge structure bridge expansion joints, on the contrary, the heat in the evening, storage and structure due to structural surface temperature above the ambient air temperature, the convective heat exchange and radiant heat exchange and thermal cooling.
