Description

A C-shaped slot-type embedded part installation combination device

technical field

The utility model belongs to the technical field of pre-embedded C-shaped groove bar-type embedded parts in concrete shear walls, and in particular relates to a C-shaped groove-shaped embedded part installation combination device.

Background technique

C-shaped groove strip embedded parts (not U-shaped), such as Hafen groove, small C Shaped steel, C-shaped channel steel, etc., as embedded parts, the C-shaped channel is mostly welded with anchor bolts. The C-shaped groove strip embedded parts are embedded in the concrete shear wall, and are pre-embedded before the shear wall reinforcement is bound and the formwork is installed. After the concrete is poured, the pre-embedded C-shaped groove should be positioned accurately, and the verticality or levelness should meet the specification requirements, and the groove should be flush with the concrete shear wall.

C-shaped groove pre-embedded positioning and fixing The conventional method is to weld the positioning support bar on the shear wall steel bar to fix it. When using wooden formwork or similar composite formwork for construction, often punch holes in the corresponding formwork for the Hafen groove, and use iron wire or other The material binds the Halfen groove and the formwork tightly to ensure that the Halfen groove does not displace during the concrete construction process and the notch is flush with the concrete surface. When aluminum alloy and other combined tool formwork is used for construction, in order to protect the integrity of the combined formwork and the number of turnover times, and give full play to the value of the formwork, it is not suitable to randomly open holes on the combined formwork, so there are the following disadvantages in actual construction:

(1) In order to ensure the accurate positioning of the C-shaped groove, it is necessary to weld a large number of positioning support steel bars, wasting materials and man-hours;

(2) It is difficult to realize the close contact between the notch and the formwork by welding the supporting ribs, and the length of the supporting ribs is difficult to control. If it is too long, the formwork will not be able to be installed or the formwork will be deformed; if it is too short, there will be a gap between the notch and the formwork and it will be filled with concrete. After the formwork is removed, the entire Hafen groove will be buried in the concrete and must be chiseled out, which is time-consuming Workmanship, quality is not guaranteed;

(3) The positioning and support of the C-shaped groove is completely realized by the support of the steel reinforcement of the shear wall. During the concrete pouring and vibration process, once the steel bars are displaced, the C-shaped groove will also be displaced, and its installation deviation will also increase;

(4) Iron wires are used to tie the C-shaped groove close to the formwork. Tightened iron wires will damage the formwork. If the iron wires are not tightened, the fixing effect will not be achieved; the tightened iron wires will be deformed or loosened by external application, and the C-shaped grooves will be displaced or lead to embedding in concrete;

(5) There are too many holes on the formwork, which is a kind of damage to the formwork and will reduce the turnover rate of the formwork.

In view of the above situation, the utility model provides a combination device for installation, positioning and fastening of C-shaped groove bar-type embedded parts. quality.
