TST桥梁伸缩缝厂家批发生产销售施工安装

TST伸缩缝不仅适用于温差变化不大南方地区，对于温差较大的我国西北，东北等地也可以使用。在全国范围内都可以正常使用。由于TST的高温粘附特性，在施工时可与现有路面牢固粘结变快，常温不粘，冷却后也不会被带走。TST伸缩缝使用寿命长，如果严格按照生产工艺安装的无缝粘接料，它的使用寿命是一般改性沥青路面的两倍左右。并且有很好的舒适性，能充分吸收各种大型车辆振动冲击，车辆驶过舒适平稳。
TST expansion joint is not only suitable for the southern region with little temperature difference, but also can be used in the northwest and northeast of China with large temperature difference. It can be used normally nationwide. Due to the high temperature adhesion characteristics of TST, it can be firmly bonded with the existing road surface during construction and become faster. It is not sticky at normal temperature and will not be taken away after cooling. TST expansion joint has a long service life. If the seamless bonding material is instalLED in strict accordance with the production process, its service life is about two times that of the general modified asphalt pavement. And has a good comfort, can fully absorb the vibration and impact of a variety of large vehicles, vehicle passing comfortable and stable.
TST伸缩缝安装注意事项：
1.伸缩缝在安装前一旦碰撞变形，很难修复为合格产品，所以在安装的全过程中，一定要采取措施保护，严禁任何车辆通过。
2.安装伸缩缝要求严格，一定要精心操作。由于现场不易调整，所以成品检查一定要认真、仔细。不合格不可运至现场。
3.伸缩缝安装前，要与设计图和现场核对位置、尺寸无误后，再稳放入预留槽。
4.桥上各接缝处缝隙一定要用聚苯乙烯泡沫板塞严，防止浇注保护带混凝土时灌入，使缝失效。同时，也不可将装置内灌进混凝土，以免更换V形象胶带时受阻。
5.伸缩缝保护带混凝土浇筑后，前七日一定要及时洒水养护，以利强度增长和防止裂缝出现。
1. once the expansion joint is deformed by collision before installation, it is difficult to repair it as a qualified product, so in the whole process of installation, we must take measures to protect it, and it is strictly prohibited for any vehicle to pass through.
2. The installation of expansion joints is strictly required and must be carefully operated. Because the site is not easy to adjust, so the inspection of finished products must be careful and careful. Disqualified can not be transported to the site.
3. Before the installation of the expansion joint, it is necessary to check the position and size with the design drawing and the site, and then steadily put it into the reserved slot.
4. The gap at the joint of the bridge must be blocked with polystyrene foam board to prevent pouring into the protective belt concrete, so that the joint failure. At the same time, the device can not be filLED with concrete, in order to avoid the replacement of V image tape blocked.
5. after the concrete pouring of the expansion joint protection belt, the first seven days must be timely sprinkling maintenance, in order to increase the strength and prevent cracks.
TST伸缩缝原理与特点
所谓“弹性接缝”就是一种粘弹性结合材料来做的接缝，使接缝产生一定的弹塑变形来适应结构的变形。其性能特点如下：
1)TST伸缩缝是一种特制的高粘弹塑性材料，常温下呈弹塑态，高温熔溶后可热灌人碎石中，成型后如同沥青砼状，能承受车辆荷载，又有弹性，可代替小伸缩缝的功能。
2)构造简单，TST碎石直接铺在桥梁接缝处，与前后的桥面铺装形成连续体，桥面平整无缝。这种弹性接缝能吸收各方面的变形和振动，行车平稳、舒适、无噪音、振动。
3)施工方便快捷，铺装冷却后，即可开放交通。当伸缩缝需要进行更换时，可半边施工。对交通繁忙路段不中断交通。
4)接缝和桥面铺装联成一体，密封防水性好，且造价低、耐用。
TST无缝伸缩缝适用一年中的各个时期，通常在零下-40℃时桥面不会变脆，在夏季高温达80℃时不会流动。
1)TST expansion joint is a kind of special high viscoelastic plastic material, elastic plastic state at room temperature, high temperature melt can be hot poured into the gravel, after forming like asphalt concrete, can bear the load of vehicles, and elastic, can replace the function of small expansion joint.
2) Simple structure, TST gravel is directly laid at the bridge joints, forming a continuum with the front and rear deck pavement, and the bridge deck is smooth and seamless. This elastic joint can absorb all aspects of deformation and vibration, driving smooth, comfortable, no noise, vibration.
3) The construction is convenient and fast. After the pavement is cooLED, the traffic can be opened. When the expansion joint needs to be replaced, half construction can be carried out. Traffic will not be interrupted on the busy road sections.
4) joint and bridge deck pavement together, sealing water resistance is good, and low cost, durable.
TST seamless expansion joint is suitable for all periods of the year, usually at minus 40 degrees Celsius when the bridge deck will not become brittle, in summer high temperature up to 80 degrees Celsius will not flow.
