Description

TECHNICAL FIELD

[0001] The utility model relates to low parapet field, concretely relates to a kind of for inverted arch low parapet surface scraping ruler. BACKGROUND

[0002] The middle-buried waterstop is one of main waterproof structure layers, and the waterstop prevents water leakage, seepage and shock absorption of building structure. In the building design of general larger project, due to the reasons such as non-continuous pouring, deformation of foundation or thermal expansion and contraction of concrete member caused by temperature change, construction joint, settlement joint and deformation joint are required to be left, and the waterstop must be installed at these joints to prevent water seepage. The waterstop is mainly used in the construction joint and deformation joint of concrete cast-in-place to become an integral part of concrete structure.

[0003] The common middle-buried waterstop is a steel plate waterstop, and the upper and lower sides of the steel plate waterstop are designed with folded edges. The folded edges can better prevent water, and at the same time, the folded edges can clearly indicate the opening direction of the steel plate waterstop, and the opening direction of the steel plate waterstop faces the water-facing surface.

[0004] During specific construction, the steel plate waterstop is pre-buried when pouring the lower layer of concrete, and half of the total height of the middle-buried steel plate waterstop is exposed outside. When pouring the concrete next time, the part of the steel plate is poured into the concrete together, so as to prevent the external pressure water from seeping in.

[0005] In order to meet the requirement of middle-buried steel plate waterstop, the traditional method is to use longitudinal steel plate waterstop fixture to position the accurate position. However, when the worker pours the concrete of low parapet, the top surface position is not accurately controlled, the manual surface collection height error is large, and the middle-buried depth of the steel plate waterstop cannot be centered.
