Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a double-pier load-bearing bracket. Background Art

[0002] Steel bridges are primarily constructed of steel. Steel bridges are characterized by high strength and rigidity, while also reducing beam height and deadweight compared to concrete bridges. During installation, steel plate girders must be cut to reduce their weight and bulk. Corbels are then constructed on the piers, and the cut steel plate girders are mounted on the corbels, welded, and finally installed on the bridge supports. However, corbels have limited bearing capacity. Excessive loads can lead to structural instability. Furthermore, during installation and removal of the corbels, they can damage the pier connections, causing cracks and posing safety risks. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides a double-pier load-bearing bracket, which solves the problem in the prior art that using corbels to support steel plate beams is not only unstable but also easily causes damage to the piers.

[0004] According to the embodiment of the present invention, the present invention adopts the following technical solutions:

[0005] A double-pier load-bearing support, erected between two supports of a bridge pier, comprising:

[0006] A first support plate and a second support plate are arranged at intervals and are both provided on the top of the pier and respectively abut against both sides of the support;

[0007] Two connecting rods, both of which are provided between the first support plate and the second support plate, for connecting the first support plate and the second support plate; and

[0008] The adjusting member is provided on the first supporting plate and is connected to the two connecting rods, and is used for adjusting the distance between the two connecting rods so that the two connecting rods respectively abut against the two supports.

[0009] Preferably, the adjusting member includes an adjusting rod passing through the first support plate and two threaded sliders sleeved on the adjusting rod and respectively connected to the two connecting rods. The adjusting rod is provided with a first threaded section, and the threaded sliders are threadedly connected to the first threaded section.

[0010] Preferably, a nut is provided at one end of the first support plate, and one end of the adjusting rod passes through the end portion of the first support plate and is fixedly connected to the nut.

[0011] Preferably, the second support plate is provided with a slot, the end of the connecting rod passes through the mouth of the slot, and the end of the connecting rod is provided with a second threaded section, the second threaded section is engaged with a nut, and the nut abuts against the side of the second support plate.

[0012] Preferably, a pressing plate is sleeved on the end of the connecting rod, and the nut is rotatably arranged on the pressing plate.

[0013] Preferably, the pressing plate is provided with a clamping block, and when the nut is engaged with the second threaded section, the clamping block is clamped in the clamping groove.

[0014] Preferably, both ends of the first support plate and both ends of the second support plate are fixedly provided with limit blocks.

[0015] Preferably, the first support plate and the second support plate are both provided with a plurality of anti-slip grooves.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this solution, a load-bearing support structure can be formed by cooperating with the first support plate, the second support plate and the connecting rod, and the load-bearing support structure can be directly erected on the bridge pier. When the end of the steel plate beam is erected on the first support plate or the second support plate, the first support plate or the second support plate is subjected to a vertical downward force, and the force is transmitted to the top of the bridge pier, and supported by the bridge pier. Under the action of the adjusting member, the two connecting rods can be respectively abutted against the two supports of the bridge pier, thereby ensuring the stability of the load-bearing support structure installed on the bridge pier. Compared with the corbel support, this solution can more evenly distribute the weight of the steel plate beam through the cooperation of the first support plate, the second support plate and the bridge pier, which can avoid the instability of the load-bearing structure caused by excessive force on a single point, and the direct erection installation method ensures that the load-bearing support structure will not cause damage to the bridge pier, thereby reducing the risk of damage to the bridge pier.

[0024] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 、 Figure 2 and Figure 5 As shown, the embodiment of the present invention proposes a double-pier load-bearing support, which is erected between two supports 2 of a pier 1 and includes:

[0026] A first support plate 3 and a second support plate 4 are arranged at intervals and are both provided on the top of the pier 1 and respectively abut against both sides of the support 2;

[0027] Two connecting rods 8, both of which are provided between the first support plate 3 and the second support plate 4, for connecting the first support plate 3 and the second support plate 4; and

[0028] The adjusting member is provided on the first supporting plate 3 and connected to the two connecting rods 8 , and is used for adjusting the distance between the two connecting rods 8 so that the two connecting rods 8 respectively abut against the two supports 2 .

[0029] In the embodiment of the present invention, pier 1 is a double-pier support structure with two columns and a matching support 2. When forming the load-bearing support, a first support plate 3 and a second support plate 4 are respectively installed on the front and rear sides of pier 1, with the front-to-back direction aligned with the bridge erection direction. The first support plate 3 and the second support plate 4 are connected by two connecting rods 8 to form a complete load-bearing support structure. During installation, bolts or other methods are not required to secure the support to pier 1. Direct installation does not damage pier 1, thereby reducing the risk of damage to pier 1. Furthermore, the load-bearing support and pier 1 are independent structures, which does not affect the integrity and long-term durability of pier 1. Furthermore, the width of the first support plate 3 and the second support plate 4 is less than the distance between the support 2 and the side of pier 1, leaving a certain usable space between the first support plate 3 or the second support plate 4 and pier 1. Later, when the steel plate girder is installed, a jack can be installed in this usable space to adjust the elevation of the steel plate girder.

[0030] Secondly, when installing the steel plate beams, the cut steel plate beams are erected on the first support plate 3 or the second support plate 4 through lifting equipment, so that the first support plate 3 or the second support plate 4 is subjected to a vertical downward force, and the force is transmitted to the top of the pier 1, and supported by the pier 1. The weight of the steel plate beam is more evenly distributed through the cooperation of the first support plate 3, the second support plate 4 and the pier 1, which can avoid excessive force on a single point and cause instability of the load-bearing structure, thereby ensuring the stability of subsequent steel plate beam welding and ensuring efficiency.

[0031] Furthermore, under the action of the adjusting member, when the first support plate 3 and the second support plate 4 are erected on the pier 1, the two connecting rods 8 can be respectively abutted against the two supports 2 of the pier 1 through the adjusting member, and the first support plate 3 and the second support plate 4 will not be positioned horizontally, and the support 2 is used to limit the position, thereby ensuring the stability of the load-bearing support structure installed on the pier 1.

[0032] Based on the above scheme, if Figure 3 As shown, the adjusting member includes an adjusting rod 6 passing through the first support plate 3 and two threaded sliders 5 sleeved on the adjusting rod 6 and respectively connected to two connecting rods 8. The adjusting rod 6 is provided with a first threaded segment 601, and the threaded slider 5 is threadedly connected to the first threaded segment 601.

[0033] By rotating the adjusting rod 6, it drives the first thread segment 601 to rotate. The rotation directions of the two first thread segments 601 are opposite, and the two threaded sliders 5 are limited and can only slide along the length direction of the first support plate 3. Therefore, under the rotation of the two first thread segments 601, the two threaded sliders 5 can be driven respectively to move away from each other along the length direction of the first support plate 3 until the connecting rod 8 provided on the threaded slider 5 abuts against the side surface of the support 2, thereby realizing the limitation of the first support plate 3 and the second support plate 4 and ensuring stability.

[0034] Specifically, such as Figure 1 As shown, a nut 602 is provided at one end of the first support plate 3, and one end of the adjusting rod 6 passes through the end of the first support plate 3 and is fixedly connected to the nut 602; with the cooperation of the nut 602, when adjusting the adjusting rod 6, auxiliary tools such as wrenches can be used to adjust the adjusting rod 6, which makes the operation more convenient and labor-saving.

[0035] Specifically, such as Figure 2 and Figure 4 As shown, the second support plate 4 is provided with a slot 301, the end of the connecting rod 8 passes through the mouth of the slot 301, and the end of the connecting rod 8 is provided with a second threaded section 801, the second threaded section 801 is engaged with a nut 7, and the nut 7 abuts against the side of the second support plate 4.

[0036] After the steel plate beam is constructed, the load-bearing bracket can be disassembled for reuse. In order to avoid directly cutting the connecting rod 8 and then welding it, the connecting rod 8 and the second support plate 4 can be assembled in an assembled manner. During assembly, the slot 301 of the second support plate 4 is directly aligned with the connecting rod 8, so that the second threaded section 801 of the connecting rod 8 protrudes from the slot 301, and the nut 7 is engaged with the second threaded section 801 and abuts against the side of the second support plate 4 to complete the limited installation of the second support plate 4; when disassembling the load-bearing bracket, the first support plate 3 and the second support plate 4 are pulled out to the left and right by unscrewing the nut 7, so that they are separated from the bridge. The top of the pier 1 can be used; and a pressing plate 701 is provided on the end of the connecting rod 8, and the nut 7 is rotatably provided on the pressing plate 701. The setting of the pressing plate 701 can increase the contact area between the nut 7 and the side surface of the second support plate 4, ensuring stability while also avoiding excessive wear; and the pressing plate 701 is provided with a clamping block 702, and when the nut 7 is engaged with the second threaded section 801, the clamping block 702 is clamped in the clamping groove 301; when the nut 7 is screwed into the second threaded section 801, the clamping block 702 of the pressing plate 701 can be clamped in the clamping groove 301, limiting the pressing plate 701 to ensure that the pressing plate 701 does not rotate when the nut 7 is screwed in.

[0037] Specifically, such as Figure 2 As shown, both ends of the first support plate 3 and the second support plate 4 are fixed with limit blocks 302, which can limit the steel plate beam erected on the first support plate 3 or the second support plate 4 to avoid side sliding.

[0038] Specifically, such as Figure 1 and Figure 2 As shown, the first support plate 3 and the second support plate 4 are both provided with a number of anti-slip grooves; during the processing of the first support plate 3 and the second support plate 4, the surfaces of the first support plate 3 and the second support plate 4 can be roughened to form a number of anti-slip grooves. The anti-slip grooves can increase the roughness of the surfaces of the first support plate 3 and the second support plate 4, thereby increasing the friction between the steel plate beam and reducing the risk of sliding.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
