Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction devices, in particular to a positioning frame for installing bridge track plates. Background Art

[0002] Track slab installation is a crucial step in bridge construction, with its precision and stability directly impacting the bridge's operational safety and durability. In traditional bridge track slab installation methods, spacers play a crucial role in securing and positioning the track slab. These spacers are bolted to the track slab, providing reliable support and a positioning reference for subsequent track slab installation.

[0003] In the prior art, the installation process of the positioning frame is relatively simple. Usually, the positioning frame is pre-placed in a predetermined position and then fixed to the track plate by bolts. However, during the installation of the track plate, due to the complexity of the construction environment and the uncontrollability of the construction operation, the bolts are easily rotated by external forces, resulting in loosening. Due to the lack of a special limiting structure, it is impossible to effectively prevent the bolts from rotating during the installation process. This loosening not only affects the stability and accuracy of the positioning frame, but may also have an adverse effect on the subsequent installation of the track plate and even cause safety hazards. Utility Model Content

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model is a positioning frame for installing a bridge track plate, comprising a positioning frame body, the positioning frame body having a fixing seat, a C-shaped plate installed on the outer surface of the fixing seat, a horizontal bar matched inside the C-shaped plate, limit blocks installed at both ends of the horizontal bar, the right-view projections of the two limit blocks are both hexagonal, a sliding mouth is provided on the C-shaped plate, a vertical plate is slidably matched inside the sliding mouth, the outer surface of the vertical plate is in contact with the horizontal bar, and a socket matched with the vertical plate is provided at the bottom of the C-shaped plate.

[0007] Furthermore, a stop block is installed at the bottom of the vertical board, and an anti-slip groove is provided on the stop block, and the stop block contacts the horizontal bar.

[0008] Furthermore, a reserved hole is opened on the vertical plate, and a pull block is installed on the top of the vertical plate.

[0009] Furthermore, rectangular blocks are installed on the outer surface of the horizontal bar, and the number of the rectangular blocks is two.

[0010] Furthermore, the positioning frame body has a support rod and a vertical rod, both ends of the support rod are provided with a vertical rod, and the fixing seat is provided at the bottom of the vertical rod.

[0011] Furthermore, a light hole is opened on the fixing seat, a bolt is fitted in the light hole, and the limit block is fitted in the bolt.

[0012] The utility model has the following beneficial effects:

[0013] The utility model limits the bolts by setting the limit blocks and the vertical plates, effectively preventing the bolts from rotating due to external forces during the installation process, thereby avoiding the problem of bolt loosening, thereby improving the stability of the positioning frame body and the track plate during the installation process, and ensuring the overall safety and durability of the bridge structure;

[0014] The utility model reinforces the horizontal bar by the provided support block, and the support block contacts the outer surface of the horizontal bar, which supports the horizontal bar and prevents the horizontal bar from displacement, thereby improving the strength of the vertical plate limiting the horizontal bar, making it more stable during operation, thereby making the limit block more firmly limit the bolt, and improving the stability of the track plate and the positioning frame body when connected.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4The utility model provides a technical solution: a positioning frame for installing a bridge track plate, including a positioning frame body 1, the positioning frame body 1 has a support rod 101 and a vertical rod 102, and vertical rods 102 are provided at both ends of the support rod 101. The fixing seat 2 is arranged at the bottom of the vertical rod 102, and a light hole is opened on the fixing seat 2. The light hole is matched with a bolt 201, and the limit block 5 is matched with the bolt 201. When the bridge track plate is installed, the track plate is fixed to the positioning frame body 1 through the bolt 201. A limit block 5 is installed. The right-view projections of the two limit blocks 5 are both hexagonal. A sliding opening 301 is provided on the C-shaped plate 3. A vertical plate 6 is slidably fitted in the sliding opening 301. A reserved hole 601 is provided on the vertical plate 6. A pull block 8 is installed on the top of the vertical plate 6. By setting the reserved hole 601 and the pull block 8, when moving the vertical plate 6, the operator only needs to pull the vertical plate 6 from the reserved hole 601 and the pull block 8, which facilitates the movement of the vertical plate 6. The outer surface of the vertical plate 6 contacts the horizontal bar 4. C The bottom of the C-shaped plate 3 is provided with a socket 302 that cooperates with the vertical plate 6. After the positioning frame body 1 and the track plate are fixed by the bolts 201, the horizontal bar 4 is moved horizontally so that the horizontal bar 4 enters the interior of the C-shaped plate 3. At this time, the two limit blocks 5 are respectively engaged with the corresponding bolts 201 to prevent the bolts 201 from rotating. At this time, the vertical plate 6 is moved to the bottom so that the bottom of the vertical plate 6 is inserted into the socket 302 and fixed, so that the vertical plate 6 limits the horizontal bar 4, thereby completing the limitation of the bolts 201.

[0023] A stop block 7 is installed at the bottom of the vertical plate 6, and anti-slip grooves are provided on the stop block 7. The anti-slip grooves can increase the stability of the stop block 7 when it contacts the horizontal bar 4. The stop block 7 contacts the horizontal bar 4. After the horizontal bar 4 is fitted into the C-shaped plate 3, when the bottom of the vertical plate 6 is fitted into the socket 302, the stop block 7 set on the vertical plate 6 contacts the outer surface of the horizontal bar 4, which supports the horizontal bar 4 while preventing the horizontal bar 4 from displacement.
