A first floor or basement roof and road square deformation joint and its construction method

Abstract

The invention provides a first floor or basement roof and road square deformation joint, which includes: a mid-buried rubber waterstop (1), a steel plate for steel bars (2), a pre-buried threaded hose (3), and an expansion joint ( 4), the waterproof layer (5) and the waterproof ointment (6), the buried rubber waterstop (1) are all welded and fixed with the steel plate (2) for the steel bar, and the buried rubber waterstop (1) has deformation hole, the center of the buried rubber waterstop (1) coincides with the centerline of the deformation joint, the waterproof layer (5) consists of two layers, which are the outdoor waterproof layer and two waterstops, and the first layer of outdoor waterproof layer closes the edge The joints and overlapping joints are tight to form a rubber ring seal. The second waterproof layer is to pre-embed two waterstops for the structural slab in the seam and take fixing measures when pouring and pounding the concrete. The waterproof ointment (6) is used for filling and fixing In the gap between the waterproof layer (5) and the expansion joint (4), the pre-embedded pipeline threaded hose (3) is installed directly below the steel plate (2) for reinforcement according to the floor position setting.

Description

technical field [0001] The invention relates to the technical field of industrial buildings and public buildings, in particular to a first-floor or basement roof-cum-road plaza deformation joint and a construction method thereof. Background technique [0002] In the prior art, there is a deformation joint pattern from the 45 node 2 on page 10J301 of the national building standard design atlas, such as figure 1 shown. Due to the deformation of the structural panels on both sides of the seam, the upper layer and the concrete protection layer often cracked. As a result, one cracked after every one was made, and water flowed into the cracks in rainy days, which even seriously affected the appearance and use of the road square. In addition, the problem of how to cross the electromechanical pipeline is not solved. In practice, the pipeline in the seam is often broken. Contents of the invention [0003] In order to overcome the three problems existing in the prior art, includin...
