Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] The construction method of reserved holes for tight-set steel casing, the construction steps are as follows:

[0036] (1), construction preparation:

[0037] (1.1) Familiar with the construction drawings, draw the reserved drawings of the pipeline holes and the production drawings of the perforated steel casings, and prepare for the technical disclosure to the operators;

[0038] (1.2) Configure the perforated steel casing that needs to be positioned, and process and manufacture the perforated steel casing according to the specification requirements and the drawings of the perforated steel casing. The perforated steel casing is composed of positioning screw 1, positioning screw base 2, and retaining Hole steel casing body 4, casing top cover 3 and nut 5 are composed, figure 1 , figure 2 and image 3 ;

[0039] (1.3) Configure the t...

Abstract

The invention discloses a hole reserving construction method for a tightly-fixed steel sleeve, which adopts a hole-reserved steel sleeve to replace a PVC sleeve which is adopted in the traditional reserving step, has the characteristics of recyclability, no nail remaining at a reserved hole, nice appearance and remarkable economical benefit, and is easy in assembly. According to the construction drawing and a structure datum point, the center of the hole is determined and used as the central position for a fixed screw, and the reserved sleeve is fixed through the tightening effect of the fixed screw. In the method, the deflection of the center of the vertical hole is adjusted by utilizing a plumb line or a laser plummet apparatus every other 5 to 8 layers, and the center of the bottom hole is led to the bottom of an upper formwork to position an upper hole, so that the deflection of the centers of two holes which are symmetric up and down caused by errors of a civil support formwork can be effectively avoided. According to the invention, a reserved hole of a finished product sleeve can be fixed by a screw so as to achieve the aims of time conservation and rapidness in assembly.

Description

technical field [0001] The invention relates to a construction method for reserved holes, in particular to a construction method for reserved holes of tight-set steel sleeves. Background technique [0002] During the construction of building water supply, drainage and heating projects, problems such as reserved holes for unavoidable installation (sanitary appliances, equipment and pipelines) are often encountered. Especially in the construction stage of residential buildings, hotels, and other similar types of buildings where kitchens and bathrooms or pipelines are relatively concentrated, the characteristics of this type of hole reservation are concentrated specifications, heavy workload, and many turnover times. The conventional construction technology of using PVC pipes or wooden boxes to leave holes will deform the holes for a large number of repeatedly pre-buried holes, and the construction safety and economy are poor. Contents of the invention [0003] The technical...
