Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a wet joint structure for a bridge. Background Art

[0002] Today's bridge construction often requires the wet-joining of several prefabricated bridge components. This so-called wet-jointing method involves prefabricating prestressed concrete beams in sections, then assembling them into a long-span continuous bridge using cantilevered beams. The joints between the prefabricated sections are then connected using cast-in-place concrete.

[0003] Currently, wet jointing requires the use of various types of formwork and rebar to create the joint structure, along with concrete pouring, to achieve the wet joint between the two sections. During both the mold installation process and the wood removal process after the wet joint is complete, there is a risk of debris falling from between the two bridge sections onto the ground, posing a construction safety hazard.

[0004] Therefore, it is urgent to research and develop a wet joint structure that can prevent dropped objects from falling and solve the above technical problems. Summary of the Invention

DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0024] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish names and does not represent a specific quantity or order.

[0025] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0027] like Figure 1-2 As shown, this embodiment provides a bridge wet joint structure comprising at least two bridge blocks 100. Each adjacent bridge block 100 has a cavity 110 between them, with a joint gap 120 for wet jointing formed at the top of each cavity 110. A plurality of spaced connecting top plates 200 are installed at the top of each joint gap 120, ensuring a pouring gap between each adjacent connecting top plates 200, ensuring that concrete can be poured into the joint gap 120.

[0028] The two ends of the connecting top plate 200 are connected to the bridge block 100 on the same side thereof, and the connection method can be screw fixing, steel bar welding, concrete pouring, etc., as long as the connection between the connecting top plate 200 and the bridge block 100 is achieved.

[0029] A casting plate 300 is provided at the bottom of the joint gap 120. The top surfaces of both ends of the casting plate 300 touch the bridge block 100 on the same side to shield the bottom of the joint gap 120. In actual use, concrete is directly poured into the joint gap 120 to connect the two bridge blocks 100.

[0030] Of course, the top ends of both sides of the casting plate 300 can also be connected to the bridge block 100 by using steel bars, screw locking, concrete pouring, etc. The casting plate 300 described in this embodiment is made of bamboo plywood.

[0031] In this embodiment, a first connecting rod 500 is preferably provided on the bridge block 100 or the connecting top plate 200. The bottom of the first connecting rod 500 extends to the bottom position of the bridge block 100 and is connected to a blocking baffle 700. The tops of both ends of the blocking baffle 700 touch and shield the bottom of the bridge block 100 on the same side of the cavity 110, thereby achieving the technical effect of blocking falling objects.

[0032] The installation of the first connecting rod 500 described in this embodiment is achieved by pre-embedding a number of sleeves with spaced arrangements on the bridge blocks. The first connecting rod 500 passes through the pre-embedded sleeves and is connected to the connecting top plate 200 at one end and to the connecting blocking partition 700 at the other end. Moreover, since the connecting top plate 200 is arranged at several spaced arrangements, the first connecting rod 500 is also matched with the connecting top plate 200 to set several spaced arrangements.

[0033] A plurality of thick wooden board layers 710 with a thickness of 2-5 cm are provided on the blocking baffle 700, a bamboo plywood layer 720 with a thickness of 2-6 mm is provided on the thick wooden board layer 710, a waterproof canvas layer is laid on the bamboo plywood layer 720, and a fireproof asbestos layer on one side is laid on the waterproof canvas layer, so as to realize the fireproof and waterproof properties of the blocking baffle 700 and improve the structural strength of the blocking baffle 700, thereby improving the blocking baffle 700's ability to withstand the impact force of falling objects.

[0034] The blocking plate 700 described in this embodiment is a channel steel.

[0035] It also includes a second connecting rod 600, the top of which is connected to the connecting top plate 200. The connecting top plate 200 is arranged in several arrangements to facilitate the subsequent pouring of concrete in the joint gap 120. A connecting bottom plate 400 is arranged in the cavity 110 below the casting plate 300. The connecting bottom plate 400 can be set to match all the connecting top plates 200 and the second connecting rod 600, or to match the connecting top plate 200. The second connecting rod 600 passes through the casting plate 300 and is connected to the connecting bottom plate 400. The height of the connecting bottom plate 400 is locked by threaded engagement on the connecting rod to ensure that the casting plate 300 touches the bottom of the bridge block 100 and covers the joint gap 120.

[0036] In addition, a connecting sleeve 610 is provided between the connecting base plate 400 and the casting plate 300. The connecting sleeve 610 is sleeved on the second connecting rod 600. The top end of the connecting sleeve 610 abuts the bottom of the casting plate 300, and the bottom end of the connecting sleeve 610 abuts the top of the connecting base plate 400, further improving the stability and sealing of the casting plate 300 in shielding the joint gap 120.

[0037] In this embodiment, the second connecting rod 600 is installed by a sleeve pre-buried on the connecting bottom plate 400 or the connecting top plate 200, thereby improving installation convenience.

[0038] The construction steps of a bridge wet joint structure provided in this embodiment are as follows:

[0039] First, a hole is reserved in the prefabricated bridge block 100, and a sleeve is embedded in the hole;

[0040] Then, the first connecting rod 500 is installed in the sleeve;

[0041] Then, the blocking plate 700 is connected to the bottom of the first connecting rod 500, and a thick wood board layer and a bamboo plywood layer are arranged on the blocking plate;

[0042] Then, a plurality of spaced connecting top plates 200 are installed on the top of the joint gap 120 , and a second connecting rod 600 is installed on the connecting top plates 200 ;

[0043] Then, the casting plate 300 is installed at the bottom of the joint gap 120 and is hoisted and connected to the bottom plate 400 through the second connecting rod 600;

[0044] Then, concrete is poured into the joint gap 120;

[0045] Finally, after the wet jointing is completed, the blocking plate 700, the connecting top plate 200, the connecting bottom plate 400 and the casting plate 300 are removed.

[0046] The present embodiment provides a bridge wet joint structure, which is different from the prior art. A connecting top plate 200 is set up at the top of the joint gap 120 at the top of the cavity 110 formed between the two bridge blocks 100, and the two ends of the connecting top plate 200 are connected to the bridge blocks 100 on the same side thereof, and a casting plate 300 is set at the bottom of the joint gap 120, and a connecting bottom plate 400 is set below the casting plate 300. The connecting bottom plate 400 and the connecting top plate 200 are connected and fixed by passing through the casting plate 300 through the first connecting rod 500, so that the two ends of the casting plate 300 are in contact with each other. The bottom of the bridge block 100 on the same side thereof shields the joint gap 120, ensuring the normal operation of the wet joint; and then the first connecting rod 500 embedded in the bridge block 100 or the connecting top plate 200 is extended to the bottom of the bridge block 100 to connect the blocking baffle 700, and the blocking baffle 700 shields the cavity 110. During the construction process of the wet joint or the disassembly process of the mold after the construction is completed, all dropped objects will fall into the cavity 110 and be blocked by the blocking baffle 700, avoiding the situation where the dropped objects fall directly to cause a safety accident, thereby improving construction safety.
