Description

Technical Field

[0001] This utility model relates to the field of bridge expansion joint technology, specifically a bridge expansion joint structure for bridge construction. Background Technology

[0002] During bridge construction, in order to prevent the bridge materials from cracking or deforming due to expansion or contraction caused by temperature changes, bridge expansion structures are used. Commonly used bridge expansion structures mainly include expansion joints, elastic supports, hinged structures, sliding devices, and expansion joints.

[0003] Traditional bridge expansion joints mostly consist of steel components on both sides and a rubber strip in the middle. The rubber strip is sandwiched between the steel components on both sides, and the expansion and contraction between the bridges is achieved through the relative displacement of the steel components. However, with this structure, the rubber strip is relatively difficult to install and remove, and after long-term use, the rubber strip is prone to oxidation and wear, which affects the normal use of the entire bridge expansion joint. To address these issues, we propose a bridge expansion structure for bridge construction. Utility Model Content

[0004] The purpose of this utility model is to provide a bridge expansion joint for bridge construction, so as to solve the problems mentioned in the background art.

[0006] The steel components are provided with L-shaped components on the top of opposite sides, and with central clamping components in the middle of opposite sides. A first clamping groove is formed between the bottom end of the L-shaped component and the top end of the central clamping component, and the end of the first rubber strip is movably clamped in the corresponding first clamping groove.

[0007] A second slot is provided between the bottom end of the middle card component and the bottom of the steel component, and the end of the second rubber strip is movably engaged in the corresponding second slot.

Detailed Implementation

[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] Example: Figure 1-4 As shown, this utility model provides a bridge expansion joint for bridge construction, including a steel component 1. The steel component 1 has two symmetrically distributed components. A first rubber strip 2 and a second rubber strip 3 are provided between the two steel components 1. The first rubber strip 2 is located above the second rubber strip 3. Connecting steel plates 4 are fixedly installed on opposite sides of the steel components 1.

[0025] L-shaped components 6 are provided on the top of opposite sides of the steel component 1, and central clamping components 7 are provided in the middle of opposite sides of the steel component 1. A first clamping groove 101 is formed between the bottom end of the L-shaped component 6 and the top end of the central clamping component 7. The end of the first rubber belt 2 is movably clamped in the corresponding first clamping groove 101.

[0026] A second slot 102 is provided between the bottom end of the middle card component 7 and the bottom of the steel component 1, and the end of the second rubber belt 3 is movably engaged in the corresponding second slot 102.

[0027] Multiple evenly distributed connecting blocks 61 are welded and installed on the side of the L-shaped component 6 near the steel component 1. The side of the steel component 1 near the L-shaped component 6 has a connecting slot 601 corresponding to the connecting blocks 61. The connecting blocks 61 are movably engaged in the corresponding connecting slots 601 to perform engagement and positioning between the L-shaped component 6 and the steel component 1. This facilitates the disassembly of the L-shaped component 6 by removing the connecting blocks 61 from the connecting slots 601, and facilitates the removal of the first rubber belt 2 from the first slot 101 for inspection and replacement.

[0028] The top of the steel component 1 is equipped with a fixed anchor rod 62. Multiple fixed anchor rods 62 are evenly distributed. The fixed anchor rods 62 are threaded through the corresponding connecting block 61 to fix the L-shaped component 6 and the steel component 1.

[0029] Multiple L-shaped locking blocks 71 are welded and installed on the side of the middle locking component 7 near the steel component 1. The side of the steel component 1 near the middle locking component 7 has an L-shaped slot 701 corresponding to the L-shaped locking blocks 71. The L-shaped locking blocks 71 are movably locked in the corresponding L-shaped slots 701 to lock and position the middle locking component 7 and the steel component 1. This facilitates the disassembly of the middle locking component 7 by removing the L-shaped locking blocks 71 from the L-shaped slots 701, and facilitates the removal of the second rubber belt 3 from the second slot 102 for inspection and replacement.

[0030] The bottom ends of the first rubber belt 2 are in contact with the upper surfaces of the corresponding middle clamping components 7. By setting the first rubber belt 2, the upward movement of the middle clamping components 7 is limited, preventing the middle clamping components 7 from moving upward.

[0031] Two steel components 1 are fixedly installed with connecting steel bars 5 at their bottom ends. The connecting steel bars 5 are provided with multiple evenly distributed ones. By setting multiple connecting steel bars 5, the two steel components 1 are connected and fixed.

[0032] The connecting steel plate 4 is provided with multiple evenly distributed ones, and each connecting steel plate 4 is fixedly installed with pre-installed steel bars 41. By setting the pre-installed steel bars 41, the two steel components 1 are pre-embedded and fixed on the bridge.

[0033] Working principle: By using pre-installed steel bars 41, two steel components 1 are pre-embedded and fixed on the bridge to install and fix the entire bridge expansion structure. The bridge expansion is connected by the steel components 1 on both sides and the first rubber strip 2 and the second rubber strip 3 between them. Since there are two rubber strips, the second rubber strip 3 can still play an expansion role when the first rubber strip 2 is oxidized and damaged, thereby improving the overall performance of the bridge expansion structure.

[0034] When it is necessary to disassemble and replace the first rubber belt 2 and the second rubber belt 3, simply remove the multiple fixed anchor rods 62 from the steel component 1 first, then move the L-shaped component 6 horizontally, and disassemble the L-shaped component 6 by removing the connecting block 61 from the connecting slot 601, so as to facilitate the removal of the first rubber belt 2 from the first slot 101 for inspection and replacement.

[0035] After the first rubber belt 2 is removed, the middle clamping component 7 loses its upward movement limit. Then, by removing the L-shaped clamping block 71 from the L-shaped clamping groove 701, the middle clamping component 7 is disassembled, which makes it easier to remove the second rubber belt 3 from the second clamping groove 102 for inspection and replacement.

[0036] 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.
