Description
Technical Field
The utility model relates to a building field, concretely relates to constructional column reinforcing bar positioning mechanism.
Background
It is now common for residential infill walls to use structural columns as a means of reinforcing the connection to the main structure and to enhance the seismic performance of the infill wall. However, the construction of the constructional column is troublesome, and the main bars of the constructional column are usually constructed by means of bar planting.
The conventional method for embedding the main reinforcements of the constructional column in the construction site comprises the steps that after a beam template at the top of the constructional column is pulled out, workers mark the pre-estimated positions of the main reinforcements of the constructional column on the beam by chalk, drill the reinforcement embedding holes which are 4mm larger than the reinforcement embedding holes in the top and the bottom of the beam by using impact electric drills, the reinforcement embedding holes are blind holes, the upper holes and the lower holes of the same beam are not communicated, then a fan is used for blowing off slag powder in the holes, then wrapping reinforcement embedding glue at the anchoring ends of rear-embedded short reinforcements, then the reinforcing steel bars are quickly inserted into the reinforcement embedding holes by holding, the reinforcement embedding glue is solidified, a reinforcement embedding and drawing test is carried out, then the main reinforcements are blanked, the upper ends and the lower ends of the main reinforcements are respectively bound with the upper short reinforcements and the lower short reinforcements which are subjected to the drawing test.
This conventional approach suffers from the following disadvantages: 1. when the rib planting hole is drilled, due to inaccurate positioning, repeated drilling is often carried out for many times, because the beam steel bars at the top of the constructional column are usually very dense, the position for drilling the rib planting hole can be very narrow, and the position for drilling and planting the rib can be very difficult to accurately find out after the mould is removed, so that a plurality of useless drilling holes are often formed at the periphery of the rib planting position of the constructional column; 2. the upper part and the lower part of the steel bar of the constructional column are not vertical, because the conventional method is operated by a bar planting worker, the steel bar planting worker cannot accurately position the steel bar, so that the upper part and the lower part of the main steel bar of the constructional column are not vertical, and the structural performance of the constructional column is poor; 3. the beam stressed main ribs on the top of the constructional column are easily damaged, and because an operator cannot identify whether the beam main ribs exist at the drilling position when drilling the bar planting hole, a drill bit of a drilling machine is easy to damage the beam stressed main ribs on the top of the constructional column during the drilling process; 4. the defects of high dust emission and high noise exist in the drilling process; 5. the same main reinforcement of each layer of constructional column is provided with two reinforcement binding joints, so that the workload is large; in summary, it is very important to provide a construction method of a constructional column without drilling and planting steel bars.

As optimization, the embedded rod is round steel wrapped with a layer of foam cotton, so that the round steel is easier to separate from the main body beam, and the grouting pipe is a steel pipe.
In this way, because the embedded rod is round steel, the round steel is prevented from directly contacting with concrete in the beam by wrapping a layer of foam cotton on the periphery of the round steel, and the surface of the round steel has no crescent pattern, so that the round steel and the foam cotton can slide up and down, and workers can save more labor when pulling out the embedded rod; the grouting pipe is arranged as the steel pipe, so that the grouting pipe is not easy to deform due to the stress change of concrete in the beam, the positioning hole is formed in the steel pipe, the limiting rigidity of the embedded rod can be guaranteed by the positioning hole, the embedded rod is not easy to shift left and right due to the stress change of the concrete, and the embedding precision of the embedded rod is guaranteed.
Preferably, the end part of the lower end of the grouting pipe is positioned between the middle part of the side surface of the main body beam and the bottom layer steel bar in the main body beam.
In this way, the positioning hole on the grouting pipe is positioned between the middle-lower part of the beam height and the lower floor steel bar, namely the middle-lower part of the embedded bar, and the steel bracket is positioned at the top end of the embedded bar, so that the positioning hole and the steel bracket are respectively positioned at two sides of the middle part of the embedded bar, and the limiting effect on the embedded bar is better; simultaneously, when the lower extreme of slip casting pipe was located the middle part of main part roof beam and the bottom reinforcing bar, space was more sufficient when pre-buried slip casting pipe in the roof beam like this, had made things convenient for the pre-buried of slip casting pipe.
Preferably, the upper end of the grouting pipe is covered with an upper cover to prevent concrete of the main body beam from entering the grouting pipe and blocking the grouting pipe.
To sum up, the beneficial effects of the utility model reside in that: through at the pre-buried positioning mechanism of major structure construction stage, when subsequent constructional column construction, the preformed hole that the embedded stick formed after extracting is vertical through-hole in the main part roof beam, need not carry out mechanical drilling on the main part roof beam, the follow-up construction process of giving the constructional column has been simplified, and the upper end through the constructional column owner muscle that has accomplished stretches into in this floor, fixed effect has been played to the constructional column owner muscle, consequently also need not be planted the muscle and also be the reinforcing bar and draw the experiment, the construction cycle of constructional column has been shortened, and the reinforcing bar joint of every floor constructional column has been reduced, workman's work load has been reduced, building material has also been practiced thrift.
