Description

Technical Field

[0001] The present application relates to the technical field of bridge structures, and in particular to a connection structure between a bridge deck and a truss. Background Art

[0002] A bridge is an important engineering structure that is built over water surfaces such as rivers, lakes, and seas to enable smooth traffic for vehicles and pedestrians.

[0003] In the connection structure between the concrete bridge deck and the truss, steel formwork is generally used as the formwork for concrete pouring.

[0004] However, the adhesion between steel formwork and concrete is often poor, which will have a negative impact on the overall stress condition of the truss beam bridge, thereby affecting the normal use of the bridge. Utility Model Content

[0005] Based on this, it is necessary to provide a connection structure between the bridge deck and the truss to address the above technical problems.

[0006] The utility model provides a connection structure between a bridge deck and a truss, which includes two connecting members, a pushing assembly and a pushing assembly. The pushing assembly is arranged on one side of the connecting member and is used to drive the two connecting members to move toward each other or move away from each other so that the two connecting members are connected or disconnected; the clamping assembly is slidably connected to the two connecting members and is used to clamp the two connected members.

[0007] In one embodiment, the pushing assembly includes a pushing member, a bidirectional screw, two sliding blocks and two groups of pulling rods. The end of the bidirectional screw is rotatably connected to the pushing member, and the two sliding blocks are threadedly connected to the bidirectional screw and slidably connected to the pushing member. One end of each group of pulling rods is hinged to two connecting members, and the other end is hinged to a sliding block. By rotating one end of the bidirectional screw, the two sliding blocks can move toward or away from each other in the length direction of the bidirectional screw to adjust the pulling angle between each group of pulling rods, so that the two groups of pulling rods drive the two connecting members to move toward or away from each other.

[0008] In one embodiment, the pushing member includes a pushing plate and an adjusting plate, the pushing member includes a pushing plate and an adjusting plate, the adjusting plate is arranged on opposite sides of the pushing plate, one end of the bidirectional screw is rotatably connected to the adjusting plate, and the other end extends out of the adjusting plate.

[0009] In one embodiment, both connecting members include a first truss and a second truss, which are connected and slidably connected on the surface of the clamping assembly. An embedding groove is provided on the end face of one first truss relative to the other first truss, and a plug-in block is provided on the end face of the other first truss relative to the embedding groove. When the two connecting members are connected, the plug-in block can be inserted into the embedding groove.

[0010] In one embodiment, the clamping assembly includes a profiled shell, conical protrusions spaced apart inside the profiled shell, fastening steel bars disposed on the conical protrusions, and fastening screws disposed between the fastening steel bars and the conical protrusions, wherein each fastening screw is evenly spaced apart between the fastening steel bars and the conical protrusions.

[0011] In one embodiment, the clamping assembly also includes a protective assembly, which includes a protective sleeve and a protective rod. The protective sleeve is arranged between the fastening steel bar and the conical protrusion and is arranged outside the fastening screw. The number of protective rods is configured to be three, and one end of the three protective rods is evenly spaced outside the protective sleeve, and the other end is arranged on the fastening steel bar.

[0012] The technical effects of the utility model are:

[0013] 1. The combination of connectors, pushing components and pressing components improves the reliability and stability of the connection structure and the concrete pavement, while reducing the cost of maintenance and replacement. In this connection structure, the pushing component can drive the connector to move toward or away from each other to achieve the connection and separation of the two connectors; and the pressing component is placed on the upper surface of the connector when the two connectors are connected, thereby improving the stability and bearing capacity of the connection. Compared with the traditional bolt connection method, the design of the pushing component and the pressing component no longer requires a large number of welded bolts, avoiding the stress and deformation problems caused by the screw welding process, and reducing the risk of cracking and falling off. At the same time, the setting of the pushing component and the pressing component can easily connect or separate the two connectors, facilitate replacement and maintenance, and save maintenance costs and time.

[0014] 2. By coordinating the vertical and transverse reinforcements, a steel grid is formed, which reduces the use of bolts when the bridge deck and truss connection structure is in use, avoiding the occurrence of residual stress and deformation during the welding process. The presence of the steel grid increases the shear bearing capacity of the connection between the concrete and the steel plate, avoiding the risk of cracking. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See Figure 1, shows a schematic diagram of a connection structure between a bridge deck and a truss in an embodiment of the present application, wherein the connection structure 100 includes a connector 10, a pushing assembly 20 and a pressing assembly 30, wherein the pushing assembly 20 is arranged on one side of the connector 10, and is used to drive the two connectors 10 to move toward or away from each other so that the two connectors 10 are closer to or farther away from each other; when the two connectors 10 are connected, the pressing assembly 30 can be placed on the upper surface of the connector 10 facing away from the pushing assembly 20 and is used to press the two connectors 10, and a concrete pavement layer 200 is provided above the pressing assembly 30. The combination of the connector 10, the pushing assembly 20 and the pressing assembly 30 improves the reliability and stability of the connection structure 100 and the concrete pavement layer 200, while reducing the cost of maintenance and replacement. In this connection structure 100, the pushing assembly 20 can drive the connector 10 to move toward or away from each other, so that the two connectors 10 can move closer to or farther away from each other, thereby adjusting the distance range between the two connectors 10, which can better adapt to different loads and load conditions, thereby reducing or avoiding vibration and displacement between the bridge deck and the truss, and improving the stability and reliability of the connection structure 100 and the concrete pavement layer 200; and the pressing assembly 30 is placed on the upper surface of the connector 10 when the two connectors 10 approach each other to a preset position, thereby improving the stability and bearing capacity of the connection. In addition, a concrete pavement layer 200 is also provided on the connection structure 100, which can not only play a protective role but also provide a comfortable and smooth road surface. Compared with the traditional bolt connection method, the design of the pushing component 20 and the clamping component 30 no longer requires a large number of welded bolts, which avoids the stress and deformation problems caused by the screw welding process and reduces the risk of cracking and falling off. At the same time, the setting of the pushing component 20 and the clamping component 30 can easily connect or separate the two connecting parts 10, facilitate replacement and maintenance, and save maintenance costs and time.

[0028] like Figure 2 As shown, Figure 3 As shown, the two connectors 10 each include a first truss 11 and a second truss 12, which are connected to each other in a T-shape. One first truss 11 is provided with an embedding groove 111 on the end face of the other first truss 11, and the other first truss 11 is provided with a plug-in block 112 on the end face of the embedding groove 111. When the two first trusses 11 move toward each other until the two first trusses 11 are connected to each other, the plug-in block 112 can be inserted into the embedding groove 111, thereby connecting the connectors 10 and further improving the connection stability and bearing capacity of the connectors 10. In addition, the first trusses 11 are slidably connected between the clamping assemblies 30, and the two connectors 10 can move toward each other or away from each other on the first truss 11. When the two connectors 10 are connected, the clamping assembly 30 can compress the two connectors 10, further improving the stability and bearing capacity of the connection.

[0029] like Figure 3 As shown, Figure 4 As shown and Figure 5 As shown, the pushing assembly 20 includes a pushing member 21, a bidirectional screw 22, two sliding blocks 23 and two sets of pulling rods 24. The pushing member 21 includes a pushing plate 211 and an adjusting plate 212. The adjusting plate 212 is arranged on opposite sides of the pushing plate 211. One end of the bidirectional screw 22 is rotatably connected to the adjusting plate 212, and the other end extends out of the adjusting plate 212. The two sliding blocks 23 are respectively connected to the positive thread and the negative thread of the bidirectional screw 22, and the two sliding blocks 23 are slidably connected to the surface of the pushing plate 211. Each set of pulling rods 24 There are two pull rods 24, one end of each set is hinged to the two first trusses 11, and the other end is hinged to the sliding block 23. By rotating the end of the bidirectional screw 22 extending outside the adjustment plate 212, the two sliding blocks 23 can move toward or away from each other along the length of the bidirectional screw 22. Each set of pull rods 24 can rotate relative to the bidirectional screw 22, and the pulling angle between each set of pull rods 24 can be adjusted, so that both sets of pull rods 24 drive the two first trusses 11 to slide toward or away from each other on the clamping assembly 30. During the process of the two first trusses 11 moving toward each other, the plug-in block 112 can be inserted into the embedding groove 111, and the clamping assembly 30 is pressed against the top of the two first trusses 11, improving the stability and bearing capacity of the connection and meeting work requirements.

[0030] like Figure 3 As shown, the clamping assembly 30 includes a profiled shell 31, a conical protrusion 32, a fastening steel bar 33 and a fastening screw 34. The profiled shell 31 is slidably connected above the first truss 11; the conical protrusions 32 are arranged at intervals inside the profiled shell 31, and the fastening steel bars 33 are arranged on the conical protrusions 32. The fastening steel bars 33 include transverse steel bars 331 and vertical steel bars 332. The transverse steel bars 331 and the vertical steel bars 332 can be connected by bonding or binding. The fastening steel bars 33 are set on the conical protrusions 32 by fastening screws 34. There are five groups of fastening screws 34 in this embodiment. Each group of fastening screws 34 is evenly spaced on the conical protrusions 32. The evenly spaced arrangement of the fastening screws 34 can also increase the uniformity and stability of the connection structure, thereby ensuring the overall performance and safety of the bridge system.

[0031] like Figure 3 As shown, Figure 4As shown, in this embodiment, the compression assembly 30 further includes a protective assembly 35, which includes a protective sleeve 351 and a protective rod 352. The protective sleeve 351 is disposed between the fastening steel bar 33 and the conical protrusion 32 and is sleeved over the fastening screw 34. There are three protective rods 352, one end of each of the three protective rods 352 is evenly spaced outside the protective sleeve 351, and the other end is disposed on the fastening steel bar 33. The provision of the protective sleeve 351 can protect the fastening steel bar from direct external impact and wear, thereby preventing the fastening steel bar 33 from being damaged or falling off. The three protective rods 352 can increase the uniformity and stability of the protective assembly 35, prevent the protective assembly 35 from deformation or sliding, and protect the stability and load-bearing capacity of the connection structure 100.

[0032] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
