Description

Technical Field

[0001] The utility model relates to the technical field of water-stop steel plates, in particular to a welding-free fixing device for water-stop steel plates. Background Art

[0002] In the construction of structures such as box culverts or basements, structural deformation and construction process requirements are usually taken into consideration during the pouring of concrete for the bottom plate, side wall plate and top plate. Construction joints need to be left in the structural parts. In order to ensure that the structural construction joints do not crack and leak during the deformation and settlement process, waterstop steel plates need to be added to the construction joints to avoid the risks of structural deformation and leakage. The traditional construction process for installing waterstop steel plates is to use welding technology to fix the waterstop steel plates, which may cause deformation and damage to the steel plates during implementation, thereby reducing the use function of the waterstop steel plates and creating quality risks for the structural functions.

[0003] When pouring the lower layer of concrete, the water-stop steel plate is embedded with a 300mm×3m steel plate, of which 10 to 15cm of the upper part is exposed outside. This part of the steel plate is poured together with the concrete next time to prevent the outside pressure water from penetrating. Therefore, the water-stop steel plate has high requirements for welding nodes, and no leaks can occur, which will affect the waterproof performance. The general construction process of the existing water-stop steel plate fixing is: steel plate positioning → fixing → positioning support rib welding → inspection and acceptance.

[0004] The waterstop steel plate should be kept on the center line of the wall as much as possible; the support welding of the waterstop steel plate is generally done by spot welding small steel bars on the main bars. Its disadvantages are: one fixed point needs to be welded on both sides of the steel plate, and the fixing efficiency is low; the position of the waterstop steel plate cannot be adjusted after it is fixed, and the horizontal and vertical position problems are difficult to adjust; when the support welding of the waterstop steel plate is carried out, it is easy to cause the waterstop steel plate to be welded through, and the rectification after welding through is time-consuming and labor-intensive, and affects the waterstop effect.
