Combined pouring template for gap of outer side opening of smoke duct

Abstract

The invention discloses a combined pouring template for a gap of an outer side opening of a smoke duct. The combined pouring template solves the problems that an existing hanging template is low in repeated utilization rate, and iron wires for hanging the template can cause the hidden danger of water leakage of a floor plate. Four kinds of universal splicing template modules are designed through square steel, wherein the first kind of splicing template modules are L-shaped large-section square steel template modules, the second kind of splicing template modules are cross-shaped large-section square steel template modules, the third kind of splicing template modules are cross-shaped small-section square steel template modules, and the fourth kind of splicing template modules are L-shaped small-section square steel template modules. For the smoke duct with the periphery not abutting against a wall, the two +-shaped large-section square steel template modules and the two cross-shaped small-section square steel template modules are combined and connected in a sleeved mode to form a square shape on the lower bottom face of the floor plate where the smoke duct is located, the four modules are tensioned and fixed under the gap of the smoke duct through split bolts, and the gap of the smoke duct is closed through the upper top face of the formed square-shaped template. Manufacturing and machining are easy, the geometric dimension deviation is small after splicing, and the combined pouring template can be used in a turnover mode.

Description

Technical field[0001]The present invention relates to a smoke trail on a cast-in-in-situ concrete building floor, and in particular, a pouring template and a method of supporting the outer cave of smoke arranged on a floor.Background technique[0002]On each floor of the currently cast concrete building, there is generally provided with a smoke, the cross section of the smoke trail is a rectangular shape. It is usually the opposite side of the wall, or the adjacent sides facing the wall. Set, there is also a four-sided facade is not rely on the wall; in order to facilitate the mounting of the smoke, the smoke ventift reserved on the floor is generally larger than the cross section of the smoke, when the smoke After the installation is completed, there is a hole gap between the outer side of the smoke wind surface, and there is a hole gap, and the slit of the hole is needed. The prior art is through the method of hanging templates, the hole gap is blocked. That is, by hanging iron wire...
