Cement mortar trowelling device for constructional engineering

Abstract

The invention provides a cement mortar trowelling device for constructional engineering, relates to the technical field of mortar trowelling, and aims to solve the problems that when an existing cement mortar trowelling device is used, different trowelling accessories cannot be mounted and replaced according to requirements, different trowelling accessories cannot be replaced and used, limitationis caused in using process, and tools need to be frequently replaced. The cement mortar trowelling device comprises a main body, a scraper blade, a pull piece and inner grooves, wherein the main bodyis of a rectangular plate-shaped structure, and a rectangular groove is formed in the top end of the main body; the scraper blade is mounted on the side edge of the main body, and the inner end of thescraper blade and a clamping plate are inserted into a mounting groove; the inner grooves are used for being formed inside the two ends of the main body, so that the ejection blocks can be mounted inside the inner grooves through springs, the ejection blocks can eject the connectors of mounting pieces or fixing heads of auxiliary pieces, the device can fix and mount the auxiliary pieces or the mounting pieces according to the use requirements, and therefore when the device is used, convenient and fast effects can be achieved.

Description

technical field [0001] The invention belongs to the technical field of mortar troweling, and more specifically relates to a construction engineering cement mortar troweling device. Background technique [0002] In the building construction process, in order to improve the anti-corrosion effect of the building exterior wall, prolong the service life of the exterior wall, protect the exterior wall body, and effectively reduce the moisture-proof and water seepage of the exterior wall during use, hang and fix the thermal insulation board on the exterior wall Finally, it is necessary to artificially smear and smooth the mortar on the outer wall, use coarse mortar to smear the base, and fine mortar to complete the smoothing of the outer wall. While the mortar is protecting the wall, it can also improve the durability of the outer wall. Flatness and ornamental use make the building wall more tidy. [0003] For example, the application number: CN202010027932.0 relates to a hand-wor...
