Construction method for quickly reserving air supply outlet casing pipes under arc-shaped stand

Abstract

The invention relates to the technical field of building construction methods, and particularly relates to a construction method for quickly reserving air supply outlet casing pipes under an arc-shaped stand. The construction method comprises the following steps that the arc-shaped radius of the arc-shaped stand is calculated according to a construction drawing, an arc-shaped stand casing pipe reserving auxiliary tool is prepared, and site construction is conducted through the arc-shaped stand casing pipe reserving auxiliary tool. According to the construction method, according to the principle that the radiuses of circles are the same, on the same arc-shaped stand, the distances between the adjacent casing pipes are the same, and the positions of the other casing pipes on the same arc line can be determined only by determining the positions of the two adjacent casing pipes; and the arc-shaped stand casing pipe reserving auxiliary tool is manufactured for auxiliary positioning, only the positions of the first two points need to be determined, the other casing pipes on the same arc line can be quickly positioned according to the auxiliary tool, the positioning accuracy is improved, the construction efficiency is improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of building construction methods, in particular to a construction method for rapidly reserving sleeves of air outlets under arc-shaped stands. Background technique [0002] The air-conditioning air supply in large venues, lecture halls, lecture halls and other buildings is under the seats. There are multiple rows of seats, and each row is arranged in an arc-shaped structure. During the construction process, the floor slabs are poured twice. The first pouring is for a thick sloping floor, and the second pouring is for stair steps. The seat air supply sleeve needs to be reserved for the first pouring of the sloping floor. There is no step as a reference, and the positioning is difficult, and the number is large. Each Both require accurate positioning, are error-prone, and have low efficiency. During the pre-embedded construction in cooperation with the reservation, casing positioning, fixing and installation ...
