Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of positioning brackets, and in particular to a positioning bracket for embedded sleeves of rail bolts. Background Art

[0002] In scenarios where large lifting equipment is used, such as port terminals, railway freight stations and container yards, track construction is the top priority of civil construction. Pre-embedded bolts are usually required in track construction. The accuracy of the positioning of these pre-embedded bolts directly affects the installation accuracy of rail fasteners. In order to ensure the accurate positioning of the pre-embedded bolts, the use of straight-rod screw designs has gradually emerged in the field of heavy-duty rails in recent years. This mainly ensures the accurate positioning of the screws through the construction process of precise secondary pre-embedded bellows sleeves. During the construction process of precise secondary pre-embedded bellows sleeves, track bolt pre-embedded sleeve positioning frames are usually used to assist in positioning the screws.

[0003] At present, there are various methods for positioning bolt embedded sleeves in cast-in-situ track beam construction. According to the material of the positioning frame components, they are mainly divided into steel plate perforated positioning or angle steel, channel steel positioning frames, etc. According to the fixing method, they are divided into auxiliary reinforcement welding fixation, bolt fixation, etc. According to the characteristics of sleeve embedded construction, there are the following disadvantages: 1. The commonly used embedded parts positioning method is the positioning plate auxiliary positioning method. Although the positioning is accurate, it will affect the subsequent concrete pouring process for relatively small components such as track beams, and it is not very suitable. 2. The method of directly welding the auxiliary reinforcement positioning on the steel cage has poor positioning accuracy and low work efficiency. It is suitable for large embedded parts, and welding can easily cause damage to the sleeve. 3. The method of auxiliary positioning with angle steel and channel steel positioning frames consumes a large amount of steel and is not very economical. At the same time, after retrieval, the publication number of the publication on March 12, 2021 is CN212689 The Chinese utility model patent of 623U discloses a steel structure anchor bolt embedded positioning frame, which is roughly described as including a horizontally arranged upper positioning member, a lower positioning member arranged parallel to and directly below the upper positioning member, and a plurality of anchor bolts vertically connecting the upper positioning member and the lower positioning member and embedded in the concrete. The upper positioning member and the lower positioning member are each provided with a plurality of first bolt holes and second bolt holes distributed circumferentially, the first bolt holes and the second bolt holes are coaxially arranged in a one-to-one correspondence, and the number of anchor bolts is equal to that of the first bolt holes. It also includes a plurality of pairs of nuts for fixing the upper positioning member and the lower positioning member on the anchor bolts, and limiting stirrups for fixing all the anchor bolts. When in use, the anchor bolts are respectively connected to the upper positioning member and the lower positioning member by installing the anchor bolts in the first bolt holes and the second bolt holes, thereby realizing auxiliary positioning during the embedding process of multiple anchor bolts.

[0004] Although the existing technical solution can be applied to auxiliary positioning construction during the pre-embedding process of anchor bolts, the position of the first bolt hole set on the upper positioning member is relatively fixed, and the position of the second bolt hole set on the lower positioning member is also relatively fixed. Therefore, when multiple anchor bolts are pre-embedded, the relative distance between two adjacent rows of anchor bolts is relatively fixed. At the same time, the structure of the upper positioning member and the structure of the lower positioning member are relatively fixed, and the flexibility of use is low. Summary of the Invention

The sleeve is conveniently connected and positioned relative to the full-thread screws through the cooperation of a plurality of nuts; the first direction and the second direction are perpendicular to each other, thereby achieving the positioning of a single sleeve and thus adjusting the relative distance between the plurality of full-thread screws installed on the first mounting square tube and the two rows of full-thread screws installed on the second mounting square tube; the main structure is assembled, which has good flexibility in use, and the assembly operation is relatively simple, the construction efficiency is high, and it is convenient to disassemble after construction, and the transportation and storage after disassembly are relatively easy. The following will be explained and introduced through multiple embodiments.

Then insert the full-thread screw 2 into the mounting hole, and use the nut 1 to fix the position of the full-thread screw 2 in the mounting hole. Seal the top and bottom ends of the sleeve 3 with the perforated plug 7 to ensure that the seal is tight, and then fix it to the full-thread screw 2 on the positioning frame with the nut 8.

[0061] 2. Initial adjustment

[0062] The positioning frame is installed in the tied steel cage. During the installation of the positioning frame, the first installation square tube 4 installed with the first assembly part is connected and assembled with the horizontal square tube 6, and then the second installation square tube 5 installed with the second assembly part is connected and assembled with the horizontal square tube 6. In this process, the two first half-set connecting frames 18 are pushed away from each other, and then the horizontal square tube 6 is made to enter the space between the two first half-set connecting frames 18. The two first half-set connecting frames 18 are pushed closer to each other, and the two first half-set connecting frames 18 are pressed against each other by the first bolts 19. The connection between the two first half-set connecting frames 18 and the horizontal support square tube 6 is realized, and the connection between the second half-set connecting frame 24 and the horizontal support square tube 6 is completed similarly. After the installation is completed, use a total station to measure and verify, adjust the horizontal and planar positions of the positioning frame, and use tools such as carpenter clamps 13 to tighten it. When the track beam is long, multiple first mounting tubes and multiple second mounting tubes can be set, and the multiple first mounting tubes can be connected end to end. Similarly, multiple second mounting tubes can be 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-thread screw 2.

[0063] 3. Final Adjustment

[0064] Use the method of pulling a horizontal line to check the elevation of the top of sleeve 3. If there is any deviation in the elevation, adjust it to meet the design requirements.

[0065] 4. Completion

[0066] After the final adjustment is completed, the reinforcement and plane position of the positioning frame are reviewed, and the positioning installation is completed after confirmation.

[0067] 5. Disassembly

[0068] After the concrete is poured and reaches a certain strength, it can be removed. During the removal process, first loosen the nut 8 at the top of the sleeve 3, and then screw (using an electric tool) the bolt cap 31 that is spot-welded to the top of the full-thread screw 2 and fixed to the full-thread screw 2 to unscrew the full-thread screw 2. After all are removed, the positioning frame can be removed.
