TST Bridge Expansion Joint Installation
1. When installing, determine the installation width according to the actual temperature.
2. The expansion joint installation process must be arranged neatly with an expansion joint device to maintain a certain inclination. Ensure that the higher plane of the telescopic device is flush with the completed bridge deck.
3. Construction method
Clean the notch to reach the designed width and depth, remove the steel bars that interfere with the embedding of the displacement box. The opening of the reserved pit must be greater than the installation width of the expansion joint. Check whether the gap between the beams of the telescopic device meets the installation temperature requirements, otherwise, use horizontal jacks and fixtures to adjust until they meet the design requirements. After adjustment, install special fixtures immediately.
According to the central position of the expansion joint, a lifting device is installed, the expansion device is installed in the slot, and the top surface of the expansion device is the same as the elevation of the bridge deck. At the same time, note that the vertical and horizontal slopes should also be consistent with the bridge deck. After the telescopic device is hoisted into the reserved groove, its center line should be aligned with the center line of the reserved gap at the beam end, and its length should be aligned with the width of the bridge. Adjust the straight section of the telescopic device and make the gap of each longitudinal beam uniform. 13785855258
TST bridge expansion joint principle:
The special and special RS elastomer, the main material of the elastomer, is heated and dissolved, and poured into the heated gravel to form a "TCS bridge joint elastomer". The gravel supports the vehicle load, and the special adhesive TCS-Z guarantees the interface strength.
TST Bridge Expansion Joint Features:
a. The TCS elastoplastic body is directly laid on the bridge joint, forming a continuum with the front and rear bridge decks or pavement. The bridge deck is smooth and seamless, and the driving is naturally smoother, more comfortable, noise-free, and vibration than the bridge with seams. It is small and has the advantages of easy maintenance, cleaning and snow removal.
b. The structure is simple, without the need to install special telescopic members and pre-embedded anchor steel bars at the beam end, the construction is convenient and fast, and the traffic can be opened after the paving is cooled.
c. This kind of elastic joint can absorb all aspects of deformation and vibration, and has high damping property, which is beneficial to bridge vibration reduction, and can meet the expansion and deformation of curved bridge, slope bridge, inclined bridge and wide bridge in three directions of vertical, horizontal and vertical directions. .
d. Because the joints and bridge deck pavement are integrated, the seal is waterproof and resistant to acid and alkali corrosion.
e. The expansion joints of the old bridge can be replaced, and the construction can be carried out on the half side, and the traffic is not interrupted on the busy road sections.
f. Low cost, durable, less maintenance and replacement, and significant economic and social benefits.
