Abstract
Description
Technical Field
[0001] This invention relates to the field of track bolt positioning and installation technology, specifically a track bolt positioning and installation method. Background Technology
[0002] In modern steel plant construction, the track foundations within the plant are pre-embedded with bolts. The biggest challenge in constructing these pre-embedded bolts lies in ensuring their installation accuracy. Conventional methods require positioning each bolt during installation, and this positioning and fixing is done on the already tied reinforcing steel in the concrete foundation. This restricts the work location and sequence, resulting in low efficiency. Furthermore, the positioning process is tedious and repetitive, consuming significant manpower, resources, and time, and it's difficult to guarantee the bolt's positional accuracy. Summary of the Invention
[0003] The present invention aims to solve the above problems and thereby provide a method for positioning and installing track bolts.
[0004] The technical solution adopted by the present invention to solve the aforementioned problem is as follows:
[0005] The installation method for track bolts shall be carried out according to the following steps:
[0006] Step 1: Perform standard concrete foundation reinforcement binding;
[0007] Step 2: Determine the installation positions of the track bolts according to the track foundation construction drawings;
[0008] Step 3: Install an adjustable bolt fixing assembly above the determined track bolt installation position. The bolt fixing assembly is fixed to the foundation steel bars below. After the track bolts are installed in the bolt fixing assembly, their position can be adjusted through the bolt fixing assembly.
[0009] Step 4: Fine-tune the position of the track bolts using the bolt fixing assembly, and then secure them with nuts after adjustment;
[0010] Step 5: Pour concrete to complete the positioning and installation of the track bolts.
[0011] Furthermore, the bolt fixing assembly includes four angle steels, which are arranged in pairs parallel to the length of the track to be installed. A gap is left between the two angle steels in each pair according to the diameter of the track bolt. The distance between the two pairs of angle steels is determined according to the distance between the two ends of the U-shaped track bolt, so that the two ends of the U-shaped track bolt can pass upward through the gap between each pair of angle steels. Support angle steels are provided below each of the four angle steels, and the support angle steels are welded and fixed to the foundation steel bars below.
[0012] Furthermore, a bolt positioning plate is provided between the two pairs of angle steels. The two sides of the bolt positioning plate rest on the two adjacent angle steels of the two pairs of angle steels respectively, and the sides are located between the gaps of each pair of angle steels. At least two pairs of latches are provided on the opposite sides of the bolt positioning plate to limit the bolt rod of the track bolt.
[0013] Furthermore, the spacing between adjacent bayonets is determined based on the spacing between two adjacent track bolts.
[0014] Furthermore, in step four, while using nuts to secure the track bolts, the ends of the track bolts will be adjusted to the design elevation.
[0015] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:
[0016] The track bolt positioning and installation method described in this invention can effectively improve construction speed, save labor costs, and improve construction quality. By welding bolt fixing components above the determined track bolt installation position, and then using the bolt fixing components to finely adjust the position of the track bolts, the track bolts can be installed quickly and accurately, improving construction speed, saving construction costs, and is simple and convenient to operate.

[0022] The present invention will be further described below with reference to embodiments, which are intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.
[0023] See Figures 1-4 The installation method for the track bolts shall be carried out according to the following steps:
[0024] Step 1: Perform standard concrete foundation reinforcement binding;
[0025] Step 2: Determine the installation position of track bolt 2 according to the track foundation construction drawings;
[0026] Step 3: Install an adjustable bolt fixing assembly 3 above the determined installation position of the track bolt 2. The bolt fixing assembly 3 is fixed to the foundation steel bar 1 below. After the track bolt 2 is installed in the bolt fixing assembly 3, the position can be adjusted through the bolt fixing assembly 3.
[0027] Step 4: Fine-tune the position of the track bolt 2 using the bolt fixing assembly 3, and then fix it with nut 21 after adjustment;
[0028] Step 5: Pour concrete to complete the positioning and installation of track bolt 2.
[0029] Furthermore, the bolt fixing assembly 3 includes four angle steels 31, which are arranged in pairs parallel to the length direction of the track to be installed. A gap is left between the two angle steels 31 in each pair according to the diameter of the track bolt 2. The distance between the two pairs of angle steels 31 is determined according to the distance between the two ends of the U-shaped track bolt 2, so that the two ends of the U-shaped track bolt 2 can pass through the gap between each pair of angle steels 31. A supporting angle steel 32 is provided below each of the four angle steels 31, and the supporting angle steel 32 is welded and fixed to the foundation steel bar 1 below.
[0030] Furthermore, a bolt positioning plate 4 is provided between the two pairs of angle steels 31. The two sides of the bolt positioning plate 4 are respectively placed on the two adjacent angle steels of the two pairs of angle steels 31, and the sides are located between the gaps of each pair of angle steels 31. At least two pairs of slots 41 are provided on the opposite sides of the bolt positioning plate 4 for limiting the bolt rod of the track bolt 2.
[0031] Furthermore, the spacing between adjacent bayonets 41 is determined based on the spacing between two adjacent track bolts 2.
[0032] Furthermore, in step four, while using nut 21 to fix track bolt 2, the end of track bolt 2 will be adjusted to the design elevation.
[0033] After the concrete has initially set, the portion of the supporting angle steel 32 that protrudes from the top of the concrete can be cut off.
[0034] The track bolt positioning and installation method described in this invention can effectively improve construction speed, save labor costs, and improve construction quality. By welding bolt fixing components above the determined track bolt installation position, and then using the bolt fixing components to finely adjust the position of the track bolts, the track bolts can be installed quickly and accurately, improving construction speed, saving construction costs, and is simple and convenient to operate.
