Rubber blanket slurry stopping process for position of prefabricated part protruding bars

Abstract

The invention discloses a rubber blanket slurry stopping process for the position of prefabricated part protruding bars. Polypropylene slurry stopping strips are replaced by rubber slurry stopping blankets, the rubber slurry stopping blankets of which the diameter is equal to that of the protruding bars can be selected according to the diameter of the protruding bars during operation, the protruding bars are sleeved with the rubber slurry stopping blankets, positions of the rubber slurry stopping blankets are adjusted so that circular washers of backseats of the rubber slurry stopping blankets can be closely attached to an inner formwork, no gap exists between the rebars and the rubber slurry stopping blankets as well as between the rubber slurry stopping blankets and the formwork, and the slurry stopping effect is achieved. Due to the fact that cylindrical rubber rings can well wrap the rebars in a fastening mode, and meanwhile baffle pieces are arranged on the rear portions of the rubber slurry stopping blankets, so that the phenomenon of loosening or falling of slurry stopping materials caused during adjustment of the length of the rebars and vibration is well eliminated, and the better slurry stopping effect is achieved.

Description

technical field [0001] The invention relates to the technical field of concrete construction, in particular to a process for preventing the slurry of rubber pads at the overhanging steel bars of prefabricated components. Background technique [0002] In the construction process of high-piled wharf, prefabricated non-prestressed concrete components are often required. When the number of non-prestressed components is large and the construction period is tight, steel formwork prefabrication is often used. Most of the prefabricated components will have overhanging steel bars. At this time, it is necessary to open holes on the steel formwork to expose the steel bars. The diameter of the openings in the formwork is a few millimeters larger than the diameter of the overhanging steel bars to facilitate the later removal of the formwork, but the concrete slurry will flow out from the aperture during concrete pouring. , it is necessary to take measures to stop the pulp. In the past, p...

Problems solved by technology

Most of the prefabricated components will have protruding steel bars. At this time, it is necessary to open holes in the steel formwork to expose the steel bars. The diameter of the formwork openings is a few millimeters larger than the diameter of the protruding steel bars to facilitate the removal of the formwork later. However, the concrete slurry will flow out of the holes during concrete pouring. , it is necessary to take anti-slurry measures. In the past, polypropylene rubber strips were usually used to wrap the gap between the exposed steel bars and the wooden formwork to achieve the anti-slurry effect. However, when the length of the extended steel bars is adjusted, the sealed anti-slurry strips are often loosened. Or fall off, the loose grout stop strips are easy to fall off when vibrating when pouring concrete, resulting in grout leakage, poor appearance quality of concrete components, and difficult repairs, etc.
