Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering construction, in particular to a combined bridge deck system. Background Art

[0002] Most of the existing bridge decks are cast in situ. Cast-in-situ bridge decks are cast as a whole according to the actual situation. The strength of this type of bridge deck is greater than that of prefabricated bridge decks, but its construction process is more complicated, which affects the construction efficiency and is more expensive. A large number of templates are used in the construction process, and the cost of the templates accounts for a large proportion of the total cost of the bridge deck. Cast-in-situ bridge decks need to be cast on site.

[0003] In order to solve this problem, the existing scheme adopts prefabricated bridge panels, and the entire bridge deck paving is completed by splicing the prefabricated bridge panels. However, in the existing scheme, the prefabricated bridge panels are easily positioned due to the later hoisting, and the assembly gap is large, which is prone to leakage in the later stage. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a combined bridge deck system which is convenient for on-site splicing.

[0005] In order to solve the above problems, the utility model provides the following technical solutions:

[0006] A combined bridge deck system comprises a plurality of prefabricated bridge decks, wherein one side of the prefabricated bridge deck is provided with a plurality of T-shaped blocks with protruding end faces along the length direction, and the other side of the prefabricated bridge deck is provided with a plurality of slots opening upward and outward along the length direction, wherein C-shaped brackets are arranged in the slots, and the C-shaped brackets correspond to the T-shaped blocks on the left and right in a one-to-one manner, and two adjacent prefabricated bridge decks are connected by inserting the T-shaped blocks buried in the C-shaped brackets.

[0007] Further technology of the utility model:

[0008] Preferably, the upper end and side wall of the C-shaped bracket are open, the open side wall is flush with the other end face of the prefabricated bridge deck, the T-block is inserted into the C-shaped bracket from top to bottom, and the opposite end faces of two adjacent prefabricated bridge decks are in contact without gap.

[0009] Preferably, the T-block is inserted into the C-shaped bracket and the groove is sealed with mortar, and the mortar is filled until it is flush with the upper surface of the prefabricated bridge deck.

[0010] Preferably, a plurality of vertical ridges are provided on the groove wall of the groove, and a vertical slot matching with the ridges is provided on the side wall of the C-shaped bracket.

[0011] Preferably, one side of the prefabricated bridge deck is provided with a transverse ridge along the length direction, and the other side is provided with a transverse groove along the length direction, and the transverse ridges and transverse grooves of two adjacent prefabricated bridge decks match each other.

[0012] The beneficial effects of the above technical solution are:

[0013] The utility model inserts the T-block of the rear bridge panel into the C-block bracket buried in the front bridge panel to form an interlocking connection. After the insertion, it is filled with mortar. There is no gap after assembly. Multiple prefabricated bridge panels are connected by the interlocking connection at the contact ends, which avoids position deviation in the splicing process of the prefabricated bridge panels. The transverse convex ridges and the matching transverse grooves at the bottom of the prefabricated bridge panels reduce the occurrence of leakage. The interlocking connection plays a positioning role, and the installation of the bridge panels becomes simpler and the connection is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 In this embodiment, a combined bridge deck system is provided, including a plurality of prefabricated bridge decks 10, wherein one side of the prefabricated bridge deck 10 is provided with a plurality of T-blocks with protruding end faces along the length direction, and the other side of the prefabricated bridge deck 10 is provided with a plurality of slots 12 with openings facing upward and outward along the length direction, wherein a C-shaped bracket is provided in the slot 12, and the C-shaped bracket corresponds to the T-shaped block on the left and right, and two adjacent prefabricated bridge decks 10 are connected by inserting the T-shaped blocks buried in the C-shaped bracket.

[0022] The upper end and side wall of the C-shaped bracket are open, and the open side wall is flush with the other end surface of the prefabricated bridge panel 10. The T-shaped block is inserted into the C-shaped bracket from top to bottom, and the opposite end surfaces of two adjacent prefabricated bridge panels 10 are in contact without gap.

[0023] In this embodiment, the slot is set to open upward and outward, and the bottom is not through. The purpose of this is that after the T-block is inserted and buried in the C-shaped bracket, and the two adjacent prefabricated bridge panels are spliced, there is no exposed connection structure when viewed from the bottom. At the same time, the T-block is directly inserted into the bottom of the slot. Compared with a through slot, there will be no misalignment between the prefabricated bridge panels up and down, which plays a limiting role.

[0024] The T-block is inserted into the C-shaped bracket and then the notch 12 is sealed with mortar 14 , which is filled until it is flush with the floor of the prefabricated bridge deck 10 .

[0025] A plurality of vertical ridges 15 are provided on the groove wall of the groove opening 12, and a vertical slot 16 cooperating with the ridges is provided on the side wall of the C-shaped bracket.

[0026] It should be noted that, in the present embodiment, the T-shaped block and the C-shaped bracket are placed during the casting process of the prefabricated bridge deck 10 and are formed integrally with the prefabricated bridge deck 10 .

[0027] The prefabricated bridge deck 10 is hoisted, and the T-shaped bracket of the rear bridge deck is inserted into the C-shaped bracket buried in the front bridge deck, such as Figure 2 , after insertion, filled with mortar 14, such as Figure 1 The mortar 14 filling can not only prevent the bridge deck from being flat, but also protect the connection structure of the T-block and the C-bracket.

[0028] The prefabricated bridge deck has a transverse ridge 17 on one side along the length direction and a transverse groove 18 on the other side along the length direction. The transverse ridges of two adjacent prefabricated bridge decks match the transverse grooves. The transverse ridges and the matching transverse grooves at the bottom of the prefabricated bridge deck reduce the occurrence of leakage.
