AI Technical Summary
In the newly built coke oven project, the embedded bolts are bent and deformed due to inadequate protection of finished products, which cannot guarantee sufficient strength, which affects later production. The existing technology mostly relies on re-embedding bolts, but due to the dense steel bars, it is difficult to bury, which is easy to destroy beam steel bars.
After the embedded bolt is set on both sides, the steel bars are embedded, and reinforced by planting rubber, welded with angle steel to form a whole, and finally secondary grouting is performed to covert reinforcement measures.
This method uses rebar and steel plate reinforcement measures to be simple, low-cost, safe and reliable, and does not affect subsequent vehicle operation and other structural installations. It effectively reinforces embedded bolts to avoid affecting later production.

Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of coke oven installation and construction in coke oven engineering, and specifically relates to a method for reinforcing a coke oven smoke guide car track with embedded bolts. Background Art
[0002] The track of the smoke guide car of the coke oven is a device that provides guidance and support for the operation of the smoke guide car. The smoke guide car is mainly used to collect and guide the smoke dust during the coal loading process of the coke oven. The track ensures that the smoke guide car can accurately move along the specified route on the top of the coke oven, so that it can be positioned above the coal loading ports of different carbonization chambers, collect the smoke dust such as raw coal gas generated during coal loading, and guide it into the dust collection system to reduce environmental pollution during the coke oven production process.
[0003] Taking the end platform section track as an example, the track structure is generally fixed to the track beam by a track pressure plate, and the track beam is fixed to the concrete slab by embedded bolts. The design and installation of the track must ensure sufficient strength to meet the weight requirements of the smoke guide car of dozens of tons. However, in newly built coke oven projects, the embedded bolts are often bent and deformed due to various external factors that are not properly protected by the finished product, and sufficient strength cannot be guaranteed, which will affect later production. Most of the existing technologies are for the reinforcement of track beams when the furnace roof is uncovered and renovated. The actual solution on site is often to re-embed the bolts. However, since the bolts need to go deep into the concrete beams and the steel bars are dense, it is very difficult to embed them and it is easy to damage the beam steel bars. Therefore, it is very necessary to invent a reinforcement method for embedded track bolts. Summary of the invention
[0004] The purpose of the invention is to provide a safe and reliable method for reinforcing the track pre-embedded bolts of a coke oven smoke guide car.
[0005] To achieve the above purpose, the technical solution of the present invention is: A method for reinforcing the track pre-embedded bolts of a coke oven smoke guide vehicle, characterized by comprising the following steps: a. Set a row of post-embedded steel bars on both sides of the embedded bolts, so that the post-embedded steel bars and the embedded bolts are in a straight line, and are evenly arranged on both sides of the embedded bolts with the track centerline as the center; b. The embedded steel bars pass through the floor slab, and the steel plates are welded under the steel bars; c. Use anchoring glue to reinforce the embedded steel bars; d. Use angle steel to weld the embedded steel bars and bolts into a whole; e. Carry out secondary grouting to conceal the later embedded steel bars and pre-embedded bolts, and complete the reinforcement of the pre-embedded bolts of the coke oven smoke guide car track.
[0006] The method for reinforcing the coke oven smoke guide car track with embedded bolts of the present invention can also be further implemented by adopting the following technical measures.
[0007] In the aforementioned method, the steel plate is a square steel plate, and the square steel plate needs to be close to the bottom of the floor slab.
[0008] In the aforementioned method, the material of the embedded steel bars is threaded steel bars, and the top of the threaded steel bars is 60 mm higher than the floor slab.
[0009] In the aforementioned method, the angle steel is an equilateral angle steel of 50 mm.
[0010] After adopting the above technical solution, the method for reinforcing the track of the coke oven smoke guide car with embedded bolts of the present invention has the following advantages: 1. Threaded steel and steel plates are used as reinforcement measures, which are simple to make and low in cost; 2. The project quality is safe and reliable, with minimal damage to existing beam and slab structures; 3. The reinforcement measures are simple and will not affect the subsequent vehicle operation or other structural installations. The embedded bolts can be effectively reinforced to avoid affecting later production. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 Schematic diagram of the embedded bolt structure of an embodiment of the present invention. DETAILED DESCRIPTION
[0012] The present invention is further described below in conjunction with embodiments and accompanying drawings.
[0013] Example 1 During the installation of the track of the middle section of the newly built coke oven project in the steel plant, it was found that the pre-embedded bolts of the track deviated about 10mm toward the coke side. The bolt position was adjusted by bending the bolts on site. After bending, the overall thread height met the requirements. However, the bending section of the bolt formed a weak part, which needed to be reinforced by the reinforcement method of the present invention.
[0014] The method for reinforcing the track pre-embedded bolts of a coke oven smoke guide vehicle of the present invention comprises the following steps: 1) Add a row of embedded steel bars on both sides of the embedded bolt 2 of the concrete beam 1, with a spacing of 650 mm between the two newly added rows of steel bars. The two newly added rows of steel bars are in a straight line with the embedded parts and are evenly arranged on both sides of the embedded bolt 2 with the track center line 6 as the center. Figure 1 Schematic diagram of the embedded bolt structure of an embodiment of the present invention.
[0015] 2) The embedded steel bars are φ22mm threaded steel bars 4, which pass through the floor slab, and a 100mm*100mm*10mm (length*width*thickness) square steel plate 3 is welded to the bottom of the threaded steel bars. The square steel plate is close to the bottom of the floor slab, and the top of the threaded steel bars is 60mm higher than the floor slab.
[0016] 3) Use anchoring glue to reinforce the steel bars.
[0017] 4) Use 50mm equilateral angle steel 5 to weld the embedded steel bars and bolts to form a whole.
[0018] 5) After the installation is completed, secondary grouting is carried out. The width of the secondary grouting layer is 700mm and the height of the grouting layer is 60mm to conceal the additional reinforcement measures.
[0019] The present invention has substantial characteristics and significant technical progress. The method for reinforcing the coke oven smoke guide car track with embedded bolts of the present invention uses threaded steel and steel plates as reinforcement measures, is simple to manufacture, has low cost, causes little damage to existing beam and plate structures, does not affect subsequent vehicle operation and other structural installations, and can effectively reinforce the embedded bolts to avoid affecting later production.
[0020] The above embodiments are only for the purpose of illustrating the present invention, but not for limiting the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and should be defined by the claims.
