Application of planting bar (bolt) technology in technical transformation

In the technical transformation, the reinforcement and reinforcement technology of the reinforced concrete structure mainly used by a factory is: bonded steel, sticky carbon fiber, and planted steel bar (bolt). One of the easiest to use, convenient, and most economical is the reinforcement of steel (bolt) technology. The construction method of this technology is as follows:

(1) Firstly, the steel bar (bolt) is unloaded according to the structural position and the steel bar (bolt) diameter and the planting hole diameter designed by the drawing;

(2) Construction of scaffolding or construction platform on the lower side of the convenient beam and column section, which is fixed and reliable;

(3) Positioning and staking the ribs (bolts) on the beam and column sections, and simultaneously rusting the steel bars;

(4) According to the concrete section size, strength and anchoring requirements of the beam and column, the price of the cement foam board should be selected by drilling the hole, the hole diameter should be larger than the diameter of the steel bar, and the hole depth should meet the design requirements or construction requirements;

(5) Use air compressors and other tools to carry out high-pressure drilling and dust removal, clean the hole surface with acetone, and seal the drill hole with cotton wool after drying to prevent debris from intruding into the hole.

(6) Select and prepare GE/MG anchoring agent on site according to the dryness and wetness of the hole. After mixing evenly, inject or insert into the anchoring section of the hole in time. The ratio of the glue used by the GEMG-1 anchoring agent to the diluent is 10B1; the mixing ratio of the GEMG-2 anchoring agent to the clean water is 1B0135;

(7) Insert the rust-removed steel bars (bolts) into the anchor holes, and vent them to fix them in place;

(8) After the glue is solidified, clean the cross section of the beam and column, and use mortar or other materials for sealing measures such as orifice sealing.

At the end of construction, the reinforcement part is cured. If the temperature of the site is above zero, the curing period can be adjusted to 4d by adjusting the mixing ratio of the adhesive. When the temperature is below zero, the temperature can be raised by the heating rod, and the construction can still be carried out. Maintenance, to meet the requirements of use. After the curing is completed, the rubber (bolt) of the glue can be pulled and tested. When the thickness of the building cannot meet the depth of the reinforcing bar (bolt), an expansion bolt (self-processing) can be added to the end of the reinforcing bar (bolt).

In the technical transformation, the problems that should be paid attention to during the construction of the planting bar (bolt):

(1) The construction technology of the planting bar (bolt) has a good use prospect in the renovation of the old reinforced concrete frame structure multi-storey building, which can save a lot of time and investment. In the presence of water, it can be applied with a GEMG2 type binder.

(2) This process must be used when the original reinforced concrete strength is greater than C15 and the concrete quality must be qualified.

(3) Sometimes the positional deviation occurs when drilling, because the original steel bar is encountered, and it needs to be strictly controlled during construction.

(4) When the process is practical, the position of the planting bar shall not be less than 50mm from the outside of the concrete foundation, otherwise the original concrete foundation will be destroyed.

Therefore, the application of the planting bar (bolt) technology can not only solve the redesign of the anchor bolt position when the equipment is updated, but also replace the equipment after the bolt breakage. Add the lifting ring and the lifting beam to the original reinforced concrete structure. The technical problems of various aspects such as the joint use of old reinforced concrete structures; and effectively overcome the limitations of site conditions, the construction period is short, and the construction cost is greatly reduced.
