[0032] Please refer to the attached Figures 1-3 In one embodiment of the utility model, a connection structure for bridge structures 30 is provided, comprising a force transmission mechanism 10 and a connection assembly 20 for connecting to the bridge structure 30, and two bridge structures 30 arranged at intervals are connected by the force transmission mechanism 10. First of all, it should be noted that the transverse direction in the present application refers to the width direction along the bridge, and the longitudinal direction refers to the direction in which the two bridge structures are arranged at intervals; which is different from the connection method in the prior art, which has the disadvantages of low rigidity, easy to be damaged after long-term use, and difficult to dismantle, which may cause inconvenience in later maintenance and replacement. The present application solves the above-mentioned defects in the prior art by providing a connection structure and system for bridge structures. The details are as follows:

[0033] The force transmission mechanism 10 includes a first force transmission part 110 and a second force transmission part 120, and the connection assembly 20 includes a connection layer 210 and an anchoring assembly 220; wherein, the first force transmission part 110 is arranged on the top of the bridge structure 30, the connection layer 210 is connected between the first force transmission part 110 and the bridge structure 30, and both ends of the first force transmission part 110 are respectively connected to the two bridge structures 30 through the connection layer 210; both ends of the second force transmission part 120 are respectively arranged at the bottoms of the two bridge structures 30, one end of the anchoring assembly 220 is pre-buried in the bridge structure 30, and the other end of the anchoring assembly 220 extends vertically downward from the bottom of the bridge structure 30, so that the second force transmission part 120 is fixedly connected to the bridge structure 30 through the anchoring assembly 220.

[0034] Specifically, the connection structure for the bridge structures 30 in this application includes a force transmission mechanism 10 and a connection assembly 20. The force transmission mechanism 10 is used to connect the two bridge structures 30 arranged at intervals so that they jointly bear the vehicle load and deform and bear force together, while the connection assembly 20 is used to stably connect the force transmission mechanism 10 to the bridge structure 30 to enhance the connection stability.

[0035] Among them, the force transmission mechanism 10 includes a first force transmission part 110 and a second force transmission part 120. The first force transmission part 110 acts as a connection member on the upper surface of the bridge structure 30 to convert the separate force-bearing of the upper surfaces of the two bridge structures 30 into joint force-bearing. Therefore, it is arranged on the top of the bridge structure 30. Since it is arranged above, if the comfort of vehicle driving needs to be ensured, it is not convenient to use a large number of connecting parts for connection. In this application, a connection layer 210 with good adhesiveness can be used for connection, so that both ends of the first force transmission part 110 are respectively connected to the two bridge structures 30 through the connection layer 210. Preferably, the connection layer 210 in this application can adopt an epoxy mortar layer. Epoxy mortar has good bonding performance, high compressive strength and durability, and is convenient for construction; while the second force transmission part 120 is used to strengthen the connection of the lower surfaces of the two bridge structures 30, so as to form an integral body in combination with the first force transmission part 110, and jointly bear force up and down, and the deformation changes from separate deformation to coordinated deformation. Therefore, it is arranged at the bottom of the bridge structure 30. Since the driving comfort does not need to be considered at the bottom and only the connection strength needs to be ensured, the second force transmission part 120 can be reinforced and connected through the anchoring assembly 220. During construction, one end of the anchoring assembly 220 can be pre-buried and anchored in the bridge structure 30 in advance, and the other end can be extended outside the bridge structure 30 for connecting the second force transmission part 120, so that the second force transmission part 120 is fixedly connected to the bridge structure 30 through the anchoring assembly 220.

[0036] As a preferred embodiment of the present utility model, the first force transmission part 110 includes a T-shaped steel plate 111. The web 113 of the T-shaped steel plate 111 is arranged between the two bridge structures 30, and both ends of the flange plate 112 of the T-shaped steel plate 111 are respectively connected to the tops of the two bridge structures 30 through the connection layer 210.

[0037] It should be noted that the T-shaped steel plate 111 has the advantages of light self-weight and high strength. Generally, the T-shaped steel plate 111 includes two parts, namely a flange plate 112 and a web 113. The web 113 can be exactly arranged in the joint seam between the two bridge structures 30, and the flange plate 112 is used to connect the upper surfaces of the two bridge structures 30, so that both ends of the flange plate 112 are respectively laid on the two bridge structures 30. During construction, an epoxy mortar layer is applied between the flange plate 112 and the bridge structure 30, and then the T-shaped steel plate 111 can be installed. It is worth noting that the thickness of the flange plate 112 should not be too large to avoid a large height difference from the bridge deck and affect the driving comfort.

[0038] As a relatively preferred embodiment of the present utility model, the second force transmission part 120 includes a horizontal steel plate 121. Both ends of the horizontal steel plate 121 are respectively arranged at the bottoms of the two bridge structures 30, and the horizontal steel plate 121 is fixedly connected to the bridge structure 30 through the anchoring assembly 220.

[0039] It should be noted that the horizontal steel plate 121 can increase the contact area with the two bridge structures 30 by using its large cross-sectional size, so that the force is distributed dispersedly and the stress concentration is reduced. It is arranged at the bottom of the bridge structure 30. During installation, the central axis of the horizontal steel plate 121 is centered between the two bridge structures 30, which means that the widths of both ends of the horizontal steel plate 121 attached to each bridge structure 30 are the same to further ensure uniform force.

[0040] As a better embodiment of the present utility model, the anchoring assembly 220 includes two positioning steel plates 221 and a plurality of embedded bolts 222. The two positioning steel plates 221 are respectively embedded in the two bridge structures 30, and a plurality of positioning holes are arranged at intervals in the transverse direction on each positioning steel plate 221. A plurality of bolt holes corresponding to the positioning holes one by one are arranged on the horizontal steel plate 121. One end of the embedded bolt 222 penetrates through the positioning hole and is embedded in the bridge structure 30, and the other end of the embedded bolt 222 extends vertically downward from the bottom of the bridge structure 30 and penetrates through the bolt hole to be fixedly connected to the horizontal steel plate 121.

[0041] It should be noted that the positioning steel plate 221 can be used to arrange a preset installation position in advance for the installation of the horizontal steel plate 121. It is embedded in the bridge structure 30. In this way, the connection strength can be ensured through the combined connection method with the embedded bolts 222. Among them, since the two ends of the horizontal steel plate 121 are respectively arranged at the bottoms of two bridge structures 30, therefore, one positioning steel plate 221 needs to be embedded in each of the two bridge structures 30 so that the two positioning steel plates 221 are arranged opposite to each other along the joint. For the convenience of the connection of the embedded bolts 222, a plurality of positioning holes can be opened in advance on each positioning steel plate 221, and the plurality of positioning holes are arranged at intervals in the transverse direction to ensure that the positioning steel plate 221 is connected by the embedded bolts 222 along the transverse direction, thereby ensuring the connection stability; for the convenience of simplifying the construction process, a plurality of bolt holes corresponding to the positioning holes one by one can be opened in advance when prefabricating the horizontal steel plate 121. Here, the one-to-one correspondence setting means that the apertures and the number of the bolt holes and the positioning holes are the same and are arranged coaxially. Among them, bolt holes are opened at both ends of the horizontal steel plate 121, and the bolt holes at each end need to correspond to the positioning holes in the positioning steel plate 221 on one side, that is, the distance between the bolt holes at both ends is the same as the distance between the two positioning steel plates 221; during construction, the positioning steel plate 221 is embedded in advance, and one end of the embedded bolt 222 is penetrated through the positioning hole in advance and anchored in the bridge structure 30. In this way, when installing the horizontal steel plate 121, due to the fact that the positioning steel plate 221 and the embedded bolt 222 are arranged in advance, only the horizontal steel plate 121 needs to be passed through the embedded bolt 222 through the bolt holes one by one and installed and attached to the bottom of the bridge structure 30, and then high-strength nuts are added for fastening. In this way, the disassembly and assembly are relatively convenient, leaving strong operability for later transformation.

[0042] Further, a filling space is formed by surrounding the T-shaped steel plate 111, the horizontal steel plate 121 and the two bridge structures 30, and a filler 130 is filled in the filling space.

[0043] It should be noted that in the filling space, the filler 130 can strengthen the connection between the T-shaped steel plate 111, the horizontal steel plate 121 and the two bridge structures 30, so that the web 113 of the T-shaped steel plate 111 can also participate in the cooperative force. The filler 130 can be cement mortar or the like.

[0044] Further, anticorrosion layers are coated on the surfaces of the T-shaped steel plate 111 and the horizontal steel plate 121.

[0045] It should be understood that since both the T-shaped steel plate 111 and the horizontal steel plate 121 are made of steel, they are prone to corrosion and rust when exposed outdoors for a long time. Therefore, an anti-corrosion layer can be coated on the surfaces of the T-shaped steel plate 111 and the horizontal steel plate 121 to play a protective role, thereby reducing the number of subsequent maintenance and replacements.

[0046] Further, the number of the positioning holes on each positioning steel plate 221 is five, and the five positioning holes are arranged at intervals in the transverse direction.

[0047] It should be noted that the number of the positioning holes can be determined according to the length of the positioning steel plate 221 in the transverse direction, so as to ensure that the positioning steel plate 221 can evenly arrange the positioning holes for the embedded bolts 222 to connect. In a preferred embodiment of the present application, the number of the positioning holes on each positioning steel plate 221 is five, and those skilled in the art can set it according to the actual situation.

[0048] Further, the width of the horizontal steel plate 121 is 1 m to 1.5 m.

[0049] It should be noted that the larger the width of the horizontal steel plate 121, the larger the contact area with the bridge structure 30, and the more convenient for load distribution. Considering the processing cost, preferably, the width of the horizontal steel plate 121 is 1 m to 1.5 m, and it can be preferably set to 1.2 m. Those skilled in the art can select according to specific needs.

[0050] The present application also provides a connection system for between bridge structures 30, including two bridge structures 30 arranged at intervals, and further including a plurality of connection structures for between bridge structures 30 as described above. The plurality of connection structures for between bridge structures 30 are arranged at intervals in the transverse direction between the two bridge structures 30.

[0051] It can be understood that considering the bridge width, a plurality of connection structures of the present application need to be arranged to ensure uniform joint force between two independent bridge structures 30. Therefore, according to the connection method of one connection structure in the present application, a plurality of the connection structures for between bridge structures 30 are arranged at intervals in the transverse direction, so as to effectively improve the connection performance between parallel bridge structures 30.

[0052] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
