Description
Technical Field
The invention belongs to the technical field of C-shaped groove pre-embedding and fixing of a concrete shear wall, and particularly relates to a method for installing and fixing a C-shaped groove strip-shaped embedded part of a minimally invasive template.
Background
Pipeline brackets such as utility tunnel pipe, pipeline vestibule, electricity distribution room, equipment room support and bury piece, slide rail etc. and bury piece and adopt C-channel shape strip-type to bury piece (non-U-shaped) mostly, like hafen groove, small-size C shaped steel, C type channel-section steel etc. as burying the piece, the C-channel has the anchor crab-bolt more to weld. The C-shaped groove strip-shaped embedded part is embedded in the concrete shear wall, and is embedded before the reinforcing steel bars of the shear wall are bound to install the template. The C-shaped groove pre-embedded after concrete pouring is accurate in positioning, the vertical degree or the horizontal degree meets the standard requirements, and the notch is flush with the concrete shear wall surface.
The conventional method for pre-embedding, positioning and fixing the C-shaped groove is to weld positioning support bars on the reinforcing steel bars of the shear wall for fixation, when a wooden template or a similar composite template is used for construction, holes are often punched on a corresponding template embedded in the Hafen groove, and the Hafen groove and the template are tightly bound by iron wires or other materials so as to ensure that the Hafen groove does not displace and the notch is flush with the concrete surface in the concrete construction process. When the combined tool templates such as aluminum alloy and the like are adopted for construction, in order to protect the combination templates to be intact and the using turnover number, the use value of the templates is fully exerted, and random holes are not suitable to be formed on the combination templates, so that the following defects exist in the actual construction:
(1) in order to ensure accurate positioning of the C-shaped groove, a large amount of positioning support steel bars need to be welded, and materials and working hours are wasted;
(2) the notch and the template are tightly attached by welding the support rib with high difficulty, and the length of the support rib is not easy to control. The longer the length, the template can not be installed or deformed; the notch and the template are short, gaps can be formed between the notch and the template and are filled with concrete, and after the template is removed, the whole Halfen groove can be buried in the concrete and needs to be chiseled out, so that the time and labor are wasted, and the quality cannot be guaranteed;
(3) the positioning and the supporting of the C-shaped groove are completely realized by the support of the shear wall steel bars, and in the concrete pouring and vibrating process, once the steel bars displace, the C-shaped groove also displaces, and the installation deviation of the C-shaped groove also increases;
(4) the C-shaped groove is tightly attached to the template by binding iron wires, the template can be damaged by the tightly twisted iron wires, and the C-shaped groove cannot play a role in fixation without being tightly twisted; the tightened iron wires can deform or relax under the action of external application, and the C-shaped groove can displace or be buried in concrete;
(5) the template is damaged due to excessive holes on the template, and the turnover utilization rate of the template can be reduced.
In view of the above situation, the invention provides a method for installing and fixing a C-shaped groove strip-shaped embedded part of a minimally invasive template, which can ensure the installation quality through a simple auxiliary device.
