Ash smearing device and construction method in large-area ground flatness control of ash smearing device

Abstract

The invention discloses an ash smearing device and a construction method in large-area ground flatness control of an ash smearing device. The ash smearing device comprises ash cakes and a scraping lever. The ash cakes are symmetrically arranged on ground base layers of the left side and the right side of the ground to be cast, and multiple ash cakes of the left side and the right side of the ground to be cast are arranged at intervals in a concrete casting direction. The ash cakes of either of the left side and the right side are provided with an angle iron guide rail, and the scraping lever is arranged between two angle steel guide rails. The construction method comprises the following steps that a level controlling line is confirmed, the ground base layer is cleaned, the ash cakes are set, the angle steel guide rails are placed, and concrete casting is performed. The ash smearing device and the construction method in large-area ground flatness control of the ash smearing device solve the technical problem that in a traditional ash smearing project, even if the flatness of the upper surfaces of the ash cakes can be ensured, when casting bottom ash is cast by exceeding the thickness of the ash cakes and the lever is scraped, the requirement for flatness of the large-area ground can still not be met.

Description

technical field [0001] The invention relates to a plastering device and a construction method for large-area cast-in-place concrete ground construction. Background technique [0002] In the construction of construction projects, the traditional construction methods of plastering are generally leveling by pulling wires, setting ash cakes (markers), marking bars, and plastering the bottom layer of ash. When plastering the ground, the thickness of the plastering is generally determined first, then the wires are pulled to level it, and then the ash cakes (markers) are placed in sequence on the ground to be poured as control points to control the flatness of the ground, and then the reinforcement is marked, and then Pour the bottom ash and scrape the bars for leveling. [0003] The disadvantage of the traditional construction method of plastering is: because the large-area cast-in-place concrete floor has high requirements for flatness, even if the flatness of the upper surface ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a plastering device and its construction method in large-area ground flatness control, to solve the problem that in traditional plastering projects, even if the flatness of the upper surface of the ash cake can be guaranteed, when pouring exceeds the ash After pouring the bottom ash with the thickness of the cake and scraping the bars, it still cannot meet the technical problem of large-area ground surface flatness requirements
