Background technique

In the scenarios where large-scale lifting equipment is used in ports, railway freight stations, and container yards, rail construction is the top priority of civil construction, in which pre-embedded bolts are usually required in rail construction. Are these pre-embedded bolts accurate or not? It directly affects the installation accuracy of rail fasteners. In order to ensure the accurate positioning of the embedded bolts, in recent years, the design of straight rod-shaped screws has gradually emerged in the field of heavy-duty rails. The construction process is used to ensure the accurate positioning of the screw, and in the construction process of the precise secondary pre-embedded bellows sleeve, the track bolt pre-embedded sleeve positioning frame is usually used to assist the positioning of the screw.

At present, there are various positioning methods for pre-embedded sleeves of cast-in-place rail beam construction bolts. According to the material of the positioning frame, it is mainly divided into steel plate perforation positioning or angle steel, channel steel positioning frame, etc. Etc., according to the characteristics of the sleeve embedded construction, the shortcomings are as follows: 1. The commonly used positioning methods for embedded parts include the positioning plate-assisted positioning method. Although the positioning is accurate, for the relatively small components such as track beams, it will It affects the subsequent concrete pouring process and is not very suitable. Second, the method of welding the auxiliary reinforcement directly to the reinforcement cage has poor positioning accuracy and low work efficiency. It is suitable for large embedded parts, and the welding is easy to cause damage to the sleeve. 3. The assisted positioning method of angle steel and channel steel positioning frame uses a large amount of steel and is not very economical. At the same time, after searching, the Chinese invention patent published on March 12, 2021 with the publication number CN212689623U discloses a steel structure ground The anchor bolt pre-embedded positioning frame is roughly described as including a horizontally arranged upper positioning member, a lower positioning member arranged in parallel directly below the upper positioning member, and several vertically connected upper positioning members and lower positioning members and embedded in concrete. Anchor bolts, the upper positioning member and the lower positioning member are respectively provided with a number of first bolt holes and second bolt holes distributed in the circumferential direction, the first bolt holes and the second bolt holes are coaxially arranged in one-to-one correspondence, and the anchor bolts are arranged with the first bolt holes and the second bolt holes. The number of bolt holes is equal, and it also includes several pairs of nuts for fixing the upper positioning piece and the lower positioning piece on the anchor bolts, and limit stirrups for fixing all the anchor bolts. The anchor bolts are installed in the first bolt hole and the second bolt hole, so as to realize the connection of the anchor bolts with the upper positioning member and the lower positioning member respectively, so as to realize the auxiliary positioning during the pre-embedding process of the multiple anchor bolts.

Although the prior art solution can be applied to the auxiliary positioning construction during the pre-embedding process of the anchor bolts, the position of the first bolt hole provided on the upper positioning member is relatively fixed, and the position of the second bolt hole provided on the lower positioning member is also relatively stable. Therefore, when multiple anchor bolts are embedded, the relative distance between the adjacent two rows of anchor bolts is relatively fixed, and the structure of the upper positioning member and the lower positioning member are relatively fixed, and the use flexibility is low. .

The connection between the half-sleeve connecting frame 18 and the horizontal support square tube 6 is completed in the same way, and the connection of the second half-sleeve connecting frame 24 relative to the horizontal support square tube 6 is completed. After the installation can be completed, use the total station to measure and review, and adjust the positioning frame. The horizontal and plane positions of the rails should be fastened with tools such as woodworking clamps 13. When the track beam is long, multiple first installation pipes and multiple second installation pipes can be set, and the multiple first installation pipes can be connected end to end. In the same way, multiple second installation pipes are connected end to end and used in series. In order to facilitate disassembly and prevent concrete pollution, lubricating oil can be brushed on the full-tooth screw 2.

3. Final tone

Use the method of pulling the horizontal line to check the elevation of the top of the sleeve 3. If there is a deviation in the elevation, adjust it to meet the design requirements.

4. Complete

After the final adjustment is completed, check the reinforcement and plane position of the positioning frame, and complete the positioning installation after confirming that it is correct.

5. Disassembly

After the concrete is poured and reaches a certain strength, it can be dismantled. During the dismantling process, first loosen the top nut 8 of the sleeve 3, and then by screwing (power tools can be used) the top of the full-thread screw 2 is spot welded with the full-thread screw 2 The fixed bolt cap 31 can be screwed out of the full-thread screw 2, and the positioning frame can be removed after all the removal.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that it can still be The technical solutions described in the foregoing embodiments are modified, or some technical features thereof are equivalently replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
