Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a road and bridge construction support device. Background Art

[0002] Bridge construction support devices, also known as bridge bearings, are a crucial component of bridge structures. Their primary function is to absorb and appropriately transfer the various loads transmitted from the superstructure to the substructure, while also allowing the bridge structure to undergo necessary movement within a certain range. This movement typically includes linear changes in the bridge structure due to temperature fluctuations, vehicle loads, wind loads, uneven foundation settlement, or earthquakes. The bearing design must allow for axial and lateral displacements, as well as axial rotation, to ensure the structure can operate safely and effectively under external loads.

[0003] There are many types of bridge bearings on the market, including thin rubber gaskets, plate-type rubber bearings with alternating layers of rubber and steel plates, spherical bearings that allow for large rotations and displacements, and sliding bearings that utilize rolling or sliding mechanisms. These various designs can provide appropriate support and movement capabilities for specific bridge applications. The selection of bridge bearings requires comprehensive consideration of factors such as bridge type, load characteristics, displacement requirements, and ease of construction and maintenance. Through precise engineering design and material selection, the proper use of bearings can significantly enhance bridge safety and durability.

[0004] In the prior art, when installing bridge supports, the bridge supports are usually lifted up on the piers by jacks and bolted to complete the connection between the bridge supports and the bottom surface of the bridge. Then, after the jacks are removed from the bottom surface of the bridge supports, concrete pads are set between the bottom of the bridge supports and the piers. This operation method is relatively common at present, but it also requires auxiliary equipment during installation, that is, construction workers are required to lift the jacks onto the piers to cooperate with the bridge supports for processing. It is impossible to first set the pads and then complete the connection between the bridge supports, piers and pads.

[0005] Therefore, a road and bridge construction support device is proposed to solve or alleviate the above problems. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a road and bridge construction support device.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A road and bridge construction support device includes a bridge support and a height adjustment component fixedly connected to the bottom surface thereof, the height of the height adjustment component is proportional to its internal volume, and the bridge support includes a connecting plate and a base fixedly connected thereto, a primary threaded hole is provided at the inner corner of the connecting plate, and a plurality of fixing plates located above the height adjustment component are fixedly connected to the outer peripheral wall of the base, a secondary threaded hole is provided on the fixing plate that is coaxially arranged with the primary threaded hole and extends into the height adjustment component, a screw is threadedly connected to both the primary threaded hole and the secondary threaded hole, and the length of the screw is greater than the maximum height difference from the connecting plate to the height adjustment component.

[0009] Preferably, the height adjustment assembly includes a top plate fixedly connected to the bottom surface of the base, a bottom plate, and a guide plate slidably connected therebetween. The top and bottom surfaces of the guide plate are inclined, and the surfaces where the top plate and the bottom plate fit with the guide plate are also inclined. The fitting surfaces between the guide plate and the top plate and the fitting surfaces between the guide plate and the bottom plate are cross-surfaces, and the secondary threaded hole is provided on the top plate.

[0010] Preferably, oblique grooves are provided on the top and bottom surfaces of both sides of the guide plate, and the top plate and the bottom plate are fixedly connected with oblique protrusions that are slidably connected.

[0011] Preferably, the side walls of the top plate and the bottom plate are provided with sliding grooves parallel to their bottom and top surfaces, and the height adjustment assembly also includes a vertically arranged connecting piece, both ends of the connecting piece are fixedly connected with sliders slidably connected in the sliding grooves, and a threaded hole is provided in the thickness direction of the connecting piece, and a positioning bolt that interferes with the side wall of the guide plate is threadedly connected in the threaded hole.

[0012] Preferably, the height adjustment assembly also includes a connecting pipe fixedly connected to the guide plate and vertically arranged, a horizontal pipe connected to the connecting pipe and horizontally arranged, and a sealing plug detachably connected to the horizontal pipe. The top plate and the bottom plate are provided with through grooves connected to the connecting pipe, and the through grooves pass through the top surface of the top plate and the bottom surface of the bottom plate respectively.

[0015] The utility model has the following beneficial effects:

[0016] During the bridge construction process, the assembly operation of the utility model is simple and efficient. Specifically, when installing this support device on the pier, the main step is to first reserve a groove that meets the specifications on the pad stone on the top of the pier, so that the bottom plate of the support device can be firmly embedded in it. Then, use the height adjustment component in the support device to place it in the reserved groove and adjust it to the required height. This process enables the upper bridge support and the bottom surface of the bridge to be smoothly connected, and through the coupling and the length of the extended screw, a stable connection is achieved. The construction process does not need to rely on complicated auxiliary devices such as traditional jacks. Once the height adjustment is complete and the bridge supports are confirmed to be in the ideal position, the construction team will then fill the cross tubes of the height adjustment components with concrete. This is done to ensure that the supports are fully consolidated in terms of structural strength. After the initial concrete pouring, in order to further improve the stability and durability of the overall structure, the staff will carefully inject concrete again into the already placed formwork. This not only greatly increases the load-bearing capacity of the support device, but also avoids any adjustments and repairs that may be required later, greatly saving time and costs. After installation, the entire structure has excellent mechanical properties, is stable and reliable, and can withstand various loads and potential environmental impacts.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] A road and bridge construction support device, such as Figure 1As shown, it includes a bridge support and a height adjustment component fixedly connected to its bottom surface. The height of the height adjustment component is proportional to its internal volume, and the bridge support includes a connecting plate 10 and a base 7 fixedly connected thereto. A primary threaded hole 11 is provided at the inner corner of the connecting plate 10. Several fixing plates 8 located above the height adjustment component are fixedly connected to the outer peripheral wall of the base 7. A secondary threaded hole 9 is provided on the fixing plate 8, which is coaxial with the primary threaded hole 11 and extends into the height adjustment component. A screw is threadedly connected to the primary threaded hole 11 and the secondary threaded hole 9. The length of the screw is greater than the maximum height difference from the connecting plate 10 to the height adjustment component.

[0022] like Figure 1 and 2 As shown, the height adjustment component includes a top plate 5 fixedly connected to the bottom surface of the base 7, a bottom plate 1, and a guide plate 3 slidably connected therebetween. The top and bottom surfaces of the guide plate 3 are inclined, and the surfaces where the top plate 5 and the bottom plate 1 fit with the guide plate 3 are also inclined. The fitting surfaces of the guide plate 3 and the top plate 5, and the fitting surfaces of the guide plate 3 and the bottom plate 1 are cross surfaces. Secondary threaded holes 9 are provided on the top plate 5, and oblique grooves 16 are provided on the top and bottom surfaces of both sides of the guide plate 3. The top plate 5 and the bottom plate 1 are fixedly connected with oblique protrusions 15 that are slidably connected. The side walls of the top plate 5 and the bottom plate 1 are provided with slide grooves 6 that are parallel to their bottom and top surfaces. The height adjustment component also includes a vertically arranged connecting piece 12, and the two ends of the connecting piece 12 are fixedly connected It is connected to a slider 14 that is slidably connected to the slide groove 6, and a threaded hole is provided in the thickness direction of the connecting piece 12, and a positioning bolt 13 that interferes with the side wall of the guide plate 3 is threadedly connected to the threaded hole. The height adjustment assembly also includes a connecting pipe 2 that is fixedly connected to the guide plate 3 and vertically arranged, a horizontal pipe that is connected to the connecting pipe 2 and horizontally arranged, and a sealing plug 4 that is detachably connected to the horizontal pipe. Specifically, the sealing plug 4 includes a threaded column and a connecting head fixedly connected to it. The cross-section of the connecting head is polygonal, and an internal thread is provided in the horizontal pipe. The threaded column is threadedly connected to the internal thread.

[0026] Then screw the screw into the primary threaded hole 11 of the connecting plate 10 of the bridge support, and then the screw enters the secondary threaded hole 9 until it enters the height adjustment assembly and collides with the top surface of the guide plate 3. At the same time, the coupling extends the upper end length of the screw to fix it to the bottom surface of the bridge.

[0027] Finally, after the formwork is connected, concrete slurry is introduced into the through hole to completely seal the height adjustment component, so that the structure is connected to the pad stone as a whole. After the connection, the support device is fixedly connected to the pier and bridge, maintaining a strong connection strength.
