Description

Technical Field

[0001] This utility model relates to the field of civil engineering bridge technology, specifically a compound main beam for civil engineering bridge construction. Background Technology

[0002] Double-deck bridges are a type of duplex bridge. They have two levels, one above the other, which can be used for different modes of transportation, such as the upper level for highways and the lower level for railways or other purposes. This design makes double-deck bridges conform to the definition of duplex architecture in terms of both function and structure, that is, to contain two or more different functions and structures in the same space.

[0003] Currently, the main beams on both sides of a double-layered bridge are supported by diagonal braces to form a triangular stable structure. However, the diagonal braces are generally fixed. When the diagonal braces between the two main beams are accidentally hit by vehicles on the bridge below, they may bend or break. The fixed diagonal braces make it difficult to replace the damaged ones, affecting the stability of the double-layered main beam and thus the stability of the double-layered bridge. To address this, we propose a double-layered main beam for civil engineering bridge construction. Utility Model Content

[0022] 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.

[0023] As mentioned in the background section, this invention addresses the problem of inconvenience in replacing damaged diagonal braces in existing technologies. It proposes a compound main beam for civil engineering bridge construction. Example

[0024] Reference Figures 1 to 3 A compound main beam for civil engineering bridge construction includes two identical beam slabs 1, which are respectively connected to the upper and lower bridge layers, and beam slabs 1 are provided on both sides of each bridge layer.

[0025] Mounting seats 2 are evenly arranged on opposite sides of the two beams 1;

[0026] Both sides of the mounting base 2 are provided with sliding grooves 3, and the mounting plate 4 is slidably connected to the sliding grooves 3 along the front and back direction;

[0027] A diagonal brace 5 is provided between the upper and lower mounting plates 4. The diagonal brace 5 supports the mounting base 2 through the mounting plates 4, thus supporting the upper bridge.

[0028] The mounting base 2 is provided with bolts 6 that connect to the mounting plate 4. The bolts 6 fix the mounting base 2 and the mounting plate 4 together, so that the mounting plate 4 can be disassembled. This allows the damaged diagonal bar 5 to be removed, and the mounting plate 4 can be slidably connected to the mounting base 2 through the sliding groove 3, making the installation of the mounting plate 4 more convenient.

[0029] Both ends of the slide rail 3 are equipped with electric guide rails 8. Electric telescopic rods 9 are installed on the output ends of the electric guide rails 8. Clamping plates 10 are installed on the output ends of the electric telescopic rods 9. The opposite sides of the clamping plates 10 are in contact with the mounting plate 4. The electric guide rails 8 are arranged in the front-back direction, and the electric telescopic rods 9 are arranged in the left-right direction. Both are powered and controlled by existing technology to facilitate use when assembling and disassembling the diagonal rod 5.

[0030] When it is necessary to remove the damaged diagonal bar 5, the corresponding electric telescopic rod 9 drives the clamping plate 10 to hold the mounting plate 4, then the bolt 6 is removed, and the electric guide rail 8 drives the electric telescopic rod 9 to move forward, so that the clamping plate 10 can move the mounting plate 4 forward away from the slide groove 3. This can save manpower to move the mounting plate 4 out of the mounting base 2. Similarly, when moving it in, the mounting plate 4 can also be inserted by clamping the mounting plate 4, thus effectively saving manpower during disassembly and assembly. Example

[0031] Reference Figure 1 and Figure 3 The outer ring of the diagonal bar 5 is fitted with a protective pad 7, which can improve the anti-collision capability of the diagonal bar 5. After the protective pad 7 is installed, the diagonal bar 5 is welded and fixed to the mounting plate 4.

[0032] The rest of the structure is the same as in Example 1.

[0033] 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.
