Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, specifically to a highway bridge construction support device. Background Technology

[0002] Bridge construction support refers to the temporary support structure system adopted during the construction of bridge foundations (such as pile foundations, abutments, and piers) and superstructure to ensure construction safety, prevent slope collapse, and control structural deformation.

[0003] Chinese Utility Model Publication No. CN222183075U discloses a support device for highway bridge construction, including a base plate, a guard plate rotatably mounted at the end of the base plate, a lower support column mounted on the base plate, and an upper support column mounted on the guard plate. The upper support column and the lower support column are connected to form a vertical fixation between the guard plate and the base plate. When the guard plate is perpendicular to the base plate, the side of the guard plate contacts the end of the base plate, and the end of the base plate provides support to the bottom of the guard plate.

[0004] This device effectively extends the device's service life. However, in practical applications, it was found that the design of adjusting the positions of the first and second wedge blocks via a rotating pull screw and threaded connection has an operational bottleneck. Because the pull screw's outer wall lacks a convenient force-applying structure, and the operating space is limited, adjusting the pull screw using the traditional rotation method requires significant operating force and is quite difficult, thus limiting its practicality and leaving room for improvement.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the prior art, the highway bridge construction support device includes a base plate 1, a guard plate 2 rotatably mounted on the left side of the base plate 1, a lower support column 3 rotatably mounted on the base plate 1, an upper support column 4 mounted on the guard plate 2, and a fixing sleeve 5 threadedly mounted at the joint of the lower support column 3 and the upper support column 4. The fixing sleeve 5 is installed at the joint of the upper support column 4 and the lower support column 3 by means of threaded connection, and the two are fixed together to form a vertical fixation between the guard plate 2 and the base plate 1.

[0025] Please see Figures 1-5 The present invention relates to a highway bridge construction support device, wherein the right side of the base plate 1 is provided with a sliding groove 6, and a blocking block 7 is slidably installed in the sliding groove 6. The blocking block 7 slides to the end side wall of the sliding groove 6 and blocks one end of the lower support column 3, preventing the lower support column 3 from continuing to rotate. The inside of the blocking block 7 is provided with a sliding groove 8, and one end of the sliding groove 8 passes through one side end face of the blocking block 7. A fixing plate 9 is slidably installed in the sliding groove 8, and a fixing block 10 is fixedly installed at the other end of the fixing plate 9. The fixing block 10 is fixedly installed in the middle of the sliding groove 6, pushing the blocking block 7 to slide in the sliding groove 6. At this time, the fixing plate 9 and the blocking block 7 move relative to each other, and the fixing plate 9 slides relative to the blocking block 7 in the sliding groove 8.

[0026] The lower part of the lower support column 3 includes a support block 11. The blocking block 7 has a rectangular cross-section, and one end face of the blocking block 7 is supported on one side end face of the support block 11. The blocking block 7 moves to the end side wall of the slide groove 6 and abuts against the end face of the support block 11 to prevent it from rotating.

[0027] The upper part of the blocking block 7 is provided with a through hole 12, and a bolt 13 is installed through the through hole 12. The upper part of the bolt 13 is higher than the upper end face of the base plate 1, which facilitates the installation of the bolt 13. The upper end face of the fixing plate 9 is provided with several threaded holes 14, and the threaded holes 14 are adapted to the bolt 13. When it is necessary to fix the blocking block 7, it can be slid to the end of the slide groove 6 to abut against the support block 11, or slid into the slide groove 6 to avoid the support block 11. After the position is determined, the bolt 13 is passed through the through hole 12 and screwed into the threaded hole 14 that is currently aligned with the through hole 12, thus completing the locking of the blocking block 7 on the fixing plate 9.

[0028] A push plate 15 is fixedly installed on the upper end face of the blocking block 7. The push plate 15 slides on the upper part of the slide groove 6. When the operator presses his / her finger on one side of the push plate 15 and pushes it, the push plate 15 slides in the slide groove 6, which in turn causes the blocking block 7 to slide in the slide groove 6.

[0029] The upper part of the push plate 15 is higher than the upper surface of the base plate 1, making it easier for staff to push the push plate 15.

[0030] In summary, this highway bridge construction support device, during use, involves placing the base plate 1 stably in the construction position, ensuring the left-side rotating guard plate 2 moves freely. The lower support column 3 is rotatably installed on the base plate 1, while the upper support column 4 is installed on the guard plate 2. A fixing sleeve 5 is installed at the joint between the upper support column 4 and the lower support column 3 via a threaded connection, fixing them together to form a vertical fixation between the guard plate 2 and the base plate 1 for support. Workers press their fingers on one side of the push plate 15 and push it. Because the upper part of the push plate 15 is higher than the upper surface of the base plate 1, it facilitates the application of force. The push plate 15 slides on the upper part of the slide groove 6, thereby causing the blocking block 7 to slide within the slide groove 6. At this time, the fixing plate 9 and the blocking block 7 move relative to each other. The fixing plate 9 slides relative to the blocking block 7 in the second groove 8, and slides the blocking block 7 to the end side wall of the first groove 6, so that one end face of the blocking block 7 is supported on one side end face of the support block 11, and abuts against the end face of the support block 11 to prevent it from rotating. The bolt 13 is passed through the upper through hole 12 of the blocking block 7 and screwed into the threaded hole 14 of the upper part of the fixing plate 9, which is currently aligned with the through hole 12, to complete the locking of the blocking block 7 on the fixing plate 9. After the support is completed, the bolt 13 is unscrewed from the threaded hole 14, and then the blocking block 7 is slid into the first groove 6 without blocking the support block 11. Then the bolt 13 is screwed into the threaded hole 14 that coincides with the through hole 12 to fix the blocking block 7 on the fixing plate 9.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
