Embodiment Construction
[0019] The method for solving the expansion joint structure of the present invention specifically comprises the following steps:
[0020] S010. Chisel the bridge deck or the construction point of house 1 (between building number building and building number building) (to figure 1 Requirements), shape the ground installation groove, and remove the ash to ensure good connectivity of the concrete; chiseling on the bridge deck or one side of the house, if there is large cement or other hard objects in the seam, do not remove it in time It will affect the expansion and contraction between the seams.
[0021] S020. Spread waterproof tape 3 that meets the standard requirements on the gap and the lowest chiseled surface 2 on both sides of the gap (to figure 2 requirements);
[0022] S030. Install stainless steel corner strips 5 on the waterproof tape 3 on both sides of the gap and on the chiseled surface 2 that is not covered with waterproof tape (such as image 3 As shown, 3 turn...

The invention relates to a method capable of solving problems existing in an expansion joint structure. The method comprises the following steps of roughening construction points of bridge floors or beam houses to obtain roughened floors in the shape of a right angle step, and thoroughly removing ash; laying and sticking waterproof adhesive tapes at the joint and on the lowest roughened floors on two sides of the joint; assembling and fixing stainless steel angle wrapping strips on the upper surfaces of the waterproof adhesive tapes at the two sides of the joint and the roughened floors not laid with waterproof adhesive tapes, and loading foam insulation adhesive on the waterproof adhesive tape in the joint; assembling a loading steel plate on the upper base surfaces of the stainless steel angle wrapping strips, fixing two sides of the loading steel plate to the bridge floors or houses, and assembling telescopic springs between outside ends of the loading steel plate and the stainless steel angle wrapping strips of turned right angles; assembling a stainless steel antiseptic decorative plate on the upper base surface of the stainless steel angle wrapping strips in the shape of the right angle and the loading steel plate; and locking and fixing the part, corresponding to the upper surface of the foam insulation adhesive, of the loading steel plate and the part, corresponding to the upper surface of the foam insulation adhesive, of the stainless steel antiseptic decorative plate to the foam insulation adhesive. The method disclosed by the invention is simple to operate, can guarantee expansion joints to be waterproof, and is good in concrete binding performance at the joint, good in stress, and convenient to mount, and high integrated intensity can be guaranteed.
Description
technical field [0001] The invention relates to the engineering technical field of building bridges and houses (between buildings and buildings), and specifically relates to a method for solving expansion joint structures. Background technique [0002] In order to meet the deformation requirements of the bridge deck and houses, expansion joints are usually set between the two ends of the bridge, between the beam end and the abutment or at the junction of the bridge; The comprehensive structural joints set up in the case of settlement and vibration can meet the needs of thermal expansion and contraction deformation. The existing solution to the expansion joint structure is prone to water leakage after a long period of use, thus affecting its service life. Contents of the invention [0003] In view of the above problems, the present invention proposes a solution to the expansion joint structure that has a reasonable concept, simple operation, can ensure that the expansion j...
