Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a positioning tool for a pre-embedded sleeve of a ballastless track beam. Background Technology

[0002] In the construction of ballastless track beams, the accurate positioning of embedded sleeves has always been a key challenge. Traditional methods for positioning embedded sleeves lack professional and effective auxiliary tools, relying heavily on manual estimation and placement based on experience. This often leads to deviations in the position of the embedded sleeves during actual operation, and their verticality is difficult to guarantee, greatly affecting the smooth progress of subsequent construction procedures.

[0003] Inaccurate positioning of the embedded sleeves can lead to several problems. First, during subsequent assembly of related components, the sleeves' positional deviation can cause inaccurate alignment, necessitating significant manpower and resources for secondary adjustments or even rework, severely slowing down construction progress. Second, it can also cause instability issues in the overall track structure, posing a potential threat to the long-term safe operation of the ballastless track. Therefore, to address these issues, a positioning fixture for embedded sleeves in ballastless track beams is proposed to meet practical application needs. Utility Model Content

[0004] This utility model provides a positioning fixture for pre-embedded sleeves of ballastless track beams, which solves the technical problem of inaccurate positioning of pre-embedded sleeves caused by relying on workers' experience.

[0005] To solve the above-mentioned technical problems, this utility model provides a positioning fixture for a pre-embedded sleeve of a ballastless track beam, including a positioning angle steel and a positioning plate. The positioning angle steel has a positioning groove on its side and a slot is formed on the bottom of the positioning plate. There are two positioning angle steels, which are placed in parallel. The positioning plate is inserted into the top of the positioning angle steel through the slot.

[0006] In some embodiments, the width of the positioning groove matches the diameter of the pre-embedded sleeve.

[0007] In some embodiments, the positioning angle steel is provided with a positioning auxiliary component, which includes a fixed mold and a movable mold. The fixed mold is fixedly installed above the positioning groove, and the movable mold is located on the side of the fixed mold. A first connecting rod and a second connecting rod are movably connected to the side of the fixed mold.

[0008] In some embodiments, the inner walls of both the fixed mold and the movable mold are semi-circular, and the fixed mold and the movable mold are combined to form a cylindrical shape that matches the pre-embedded sleeve.

[0009] In some embodiments, the number of positioning aids is the same as the number of positioning slots.

[0010] In some embodiments, the first link and the second link are parallel to each other.

[0011] In some embodiments, the positioning aid component further includes a crossbar, which is fixedly mounted on the side of the movable mold.

[0012] In some embodiments, the bottom edge of the positioning plate is abutted against the top edge of the crossbar.

[0013] Compared with related technologies, the positioning fixture for the pre-embedded sleeve of the ballastless track beam provided by this utility model has the following advantages:

[0014] Beneficial effects:

[0015] This utility model provides a positioning fixture for pre-embedded sleeves in ballastless track beams. The positioning angle steel is made of angle steel material, and the positioning groove is precisely drilled according to the bridge construction drawings. The width of the groove is precisely matched with the diameter of the pre-embedded sleeve. With the combination of the slot of the positioning plate and the insertion design of the positioning angle steel, the accurate positioning of the pre-embedded sleeve is ensured from multiple dimensions. This effectively solves the position deviation problem caused by traditional manual positioning methods and provides a solid foundation for the accurate docking of subsequent construction components.

[0016] This utility model provides a positioning fixture for pre-embedded sleeves in ballastless track beams, and the setting of positioning auxiliary components further improves the positioning effect. The fixed mold and the movable mold form a cylindrical shape adapted to the pre-embedded sleeve. Under the linkage of the first link and the second link, the movable mold can hold one side of the pre-embedded sleeve with its own weight, increasing the lateral positioning capability, reducing the risk of displacement of the sleeve due to external forces during construction, and ensuring the positional stability of the pre-embedded sleeve in complex construction environments.

[0022] Example 1

[0023] This embodiment provides a positioning fixture for a pre-embedded sleeve on a ballastless track beam, such as... Figure 1 As shown, this utility model includes a positioning angle steel 1 and a positioning plate 2. A positioning groove 11 is provided on the side of the positioning angle steel 1, and a slot 12 is provided on the bottom of the positioning plate 2. There are two positioning angle steels 1, placed parallel to each other. The positioning plate 2 is inserted into the top of the positioning angle steel 1 through the slot 12. The width of the positioning groove 11 matches the diameter of the pre-embedded sleeve.

[0024] In this embodiment, the positioning angle steel 1 is made of ∠63*63 angle steel material. The positioning groove 11 is precisely drilled according to the requirements of the bridge construction drawings. Then, the two positioning angle steels 1 are placed on the beam formwork. The slots 12 of multiple positioning plates cooperate with the positioning angle steels 1 to position the two positioning angle steels 1. Then, the positioning angle steels 1 are fixed, thereby using the positioning groove 11 to accurately position the pre-embedded sleeve.

[0025] Example 2

[0026] Based on Example 1, such as Figure 2-3 As shown, the positioning angle steel 1 in this embodiment is provided with a positioning auxiliary component 3. The positioning auxiliary component 3 includes a fixed mold 31 and a movable mold 32. The fixed mold 31 is fixedly installed above the positioning groove 11, and the movable mold 32 is located on the side of the fixed mold 31. The side of the fixed mold 31 is movably connected to a first connecting rod 33 and a second connecting rod 34. The inner walls of the fixed mold 31 and the movable mold 32 are both semi-circular. The fixed mold 31 and the movable mold 32 are combined to form a cylindrical shape that matches the pre-embedded sleeve. The number of positioning auxiliary components 3 is the same as the number of positioning grooves 11. The first connecting rod 33 and the second connecting rod 34 are parallel to each other.

[0027] In this embodiment, the fixed mold 31 and the movable mold 32 are used to further position the embedded sleeve. The first connecting rod 33 and the second connecting rod 34, which are parallel to each other, allow the movable mold 32 to move along a certain route. The movable mold 32 can also use its own weight to hold one side of the embedded sleeve, increasing the positioning capability of the embedded sleeve. After the embedded sleeve is fixed, the movable mold 32 can move freely when the positioning angle steel 1 is removed, without affecting the removal efficiency.

[0028] Example 3

[0029] Based on Example 1, such as Figure 4 As shown, the positioning auxiliary component 3 in this embodiment also includes a crossbar 35, which is fixedly installed on the side of the movable mold 32, and the bottom edge of the positioning plate 2 is in contact with the top edge of the crossbar 35.

[0030] In this embodiment, the positioning plate 2 is used to press down the crossbar 35, which further increases the pressure on the movable mold 32, thereby increasing the ability to position the pre-embedded sleeve and preventing the pre-embedded sleeve from moving.
