Description

Technical Field

[0001] This invention relates to the field of bridge bearing pad technology, and in particular to a construction method for bearing pads used in road and bridge construction. Background Technology

[0002] The pad stone is set at the top of the abutment and pier and the connection with the support. It is mostly cast in place with concrete. The reinforcing steel of the pad stone is connected by spot welding. When constructing the abutment cap beam, attention should be paid to the placement of the embedded steel bars. The top surface of the pad stone must be kept flat and clean to ensure a tight fit with the support. When the support has uneven bearing or aging, it is necessary to replace the support and recast the pad stone.

[0003] When replacing a bearing, the original pad stone must first be destroyed. After the pad stone is broken, the resulting debris and reinforcing bars are cleaned up, and then new holes are drilled to install the reinforcing bar support. Concrete is then poured around the pad stone using a cast-in-place slab. Although this method can reshape the pad stone, it is difficult to determine the location of the holes drilled in the reinforcing bars of the destroyed pad stone. Furthermore, when fixing the cast-in-place slab, upper limit bolts need to be installed on the base surface to be used for positioning via triangular plates, making the process very troublesome. Therefore, this invention proposes a construction method for re-casting pad stones when replacing bearings. Summary of the Invention

[0004] The purpose of this invention is to at least address one of the aforementioned technical deficiencies.

[0005] The purpose of this invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a method for constructing support pad stones for roads and bridges.

[0006] The objective of this invention is achieved through the following technical solution: a construction method for a road and bridge support pad, wherein the road and bridge support pad includes a frame 2, horizontal bars 3, vertical bars 4, reinforcing bars 5, a mesh plate 6, a pad 7, a baffle 8, and a limiting plate 9. The construction method based on this road and bridge support pad includes the following steps:

[0007] S1. The position of the vertical rod 4 is set at the gap between the two corresponding steel bars 5. The gap position of the steel bars 5 is determined according to the position of the vertical rod 4. The original pad stone 7 is destroyed by using an electric hammer to avoid the internal steel bars 5. The bottom of the original pad stone 7 is dug deeper and the embedded steel bars are removed, thus completing the first step of destroying the original pad stone 7.

[0008] S2. Clean up the steel bars and gravel generated from the original foundation stone 7;

[0009] S3. Drill new holes according to the position of frame 2 and install the new casting frame;

[0010] S4. Install baffles 8 around the casting frame and limit them with limiting plates 9. If there is a small error between the limiting plate 9 and the vertical bar 4, the vertical bar 4 can be bent with a hammer.

[0011] S5. Re-pour concrete inside the casting frame to complete the new foundation stone 7.

[0012] A support pad for road and bridge includes a base surface, a frame is provided inside the base surface, a horizontal bar is fixedly connected to the outer surface of the frame, a vertical bar is fixedly connected to the end of the horizontal bar, a steel bar is inserted inside the frame, a mesh plate is fixedly connected inside the steel bar, a pad is provided inside the steel bar and the mesh plate, a baffle is overlapped on one side of the pad, a limiting plate is overlapped on one side of the baffle, and the other side of the limiting plate overlaps with the vertical bar.

[0013] Preferably, the frame is made of steel, the inner diameter of the frame is larger than the size of the pad stone, the frame is embedded in the base surface, and the top surface of the frame is parallel to the base surface.

[0014] By adopting the above technical solution, it is easy to determine the location of the newly poured foundation stone.

[0015] Preferably, the frame is a rectangular frame, with horizontal bars welded to all four sides of the frame. Three horizontal bars are welded to one side of each of the two long sides of the frame, and two horizontal bars are welded to one side of each of the two short sides of the frame. Vertical bars are welded to the ends of the horizontal bars. Both the horizontal bars and the vertical bars are made of steel bars, and the top surface of the vertical bar is four centimeters above the base surface.

[0016] By adopting the above technical solution, the protruding vertical rod can overlap and cooperate with the limiting plate to limit the position of the baffle.

[0017] Preferably, the base surface has an insertion hole on the side near the inner wall of the frame, and a steel bar is inserted into the insertion hole. The number of steel bars is several, and the several steel bars are evenly distributed inside the frame. The number of mesh plates is three, and the three mesh plates are linearly arranged on one side of the steel bars. The mesh plates are connected to the steel bars by welding.

[0018] By adopting the above technical solution, the casting frame composed of the mesh plate and the reinforcing bars is inserted into the hole through the reinforcing bars, which facilitates the subsequent pouring of concrete.

[0019] Preferably, the baffle is composed of four rectangular plates, the shape of the baffle is a rectangular frame, the internal dimension of the baffle is larger than the combination of the crossbar and the mesh plate, the interior of the baffle is filled with pad stones, the height of the baffle is greater than the height of the pad stones, and the material of the baffle is a wooden board.

[0020] By adopting the above technical solution, the four wooden baffles can be placed according to the position of the frame.

[0021] Preferably, the limiting plate is a right-angled triangle plate, the number of limiting plates is the same as the number of vertical bars, one right-angled side of the limiting plate overlaps with the baffle, the other right-angled side of the limiting plate overlaps with the base surface, and the material of the limiting plate is wood.

[0022] By adopting the above technical solution, multiple limiting plates can position the four sides of the baffle.

[0023] Preferably, the mesh panel is welded from a number of long rods and a number of short rods, the reinforcing bars surround the inner wall of the frame to form a rectangular frame, the mesh panel is adapted to the rectangular frame, and the connection between the mesh panel and the reinforcing bars is wrapped with iron wire.

[0024] By adopting the above technical solution, the wire is first used for positioning, and then welded to fix it, thus facilitating welding.

[0025] Preferably, the length of the horizontal bar is adapted to the length of the bottom edge of the limiting plate, and the connection angle between the horizontal bar and the vertical bar is ninety degrees.

[0026] By adopting the above technical solution, when destroying the original pad stone, the gap position of the reinforcing bars can be determined according to the position of the vertical bar, which makes it easier to destroy the original pad stone with an electric hammer, avoiding the internal reinforcing bars and achieving the purpose of protecting the electric hammer.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1. The bridge and road use a supporting pad stone construction method. By setting up a frame, a frame is set inside the base surface. Horizontal bars are fixedly connected to the outer surface of the frame, and vertical bars are fixedly connected to the ends of the horizontal bars. The frame is embedded in the base surface. The position of the frame corresponds to the position of the support. After the original pad stone is destroyed and the debris and reinforcing steel are cleaned, holes are drilled again according to the position of the frame and a new pouring frame is installed. Baffles are installed around the pouring frame and limited by limiting plates. Concrete is poured again in the pouring frame to complete the new pad stone. The limiting plates can be directly connected to the vertical bars. The frame design can quickly locate the position of the new pad stone. The position of the frame is the position of the baffle, which facilitates the re-pouring of the pad stone.

[0029] 2. The bridge uses a supporting pad stone construction method. Vertical rods are installed, and the ends of horizontal rods are fixedly connected to vertical rods. The other side of the limiting plate overlaps with the vertical rod. The position of the vertical rod corresponds to the gap between two reinforcing bars. When damaging the original pad stone, the gap position of the reinforcing bars can be determined according to the position of the vertical rod, which makes it easy to use an electric hammer to damage the original pad stone. The internal reinforcing bars can be avoided, thus protecting the electric hammer. If there is a slight error between the limiting plate and the vertical rod, the vertical rod can be bent with a hammer for reuse. The vertical rod can be used every time a new pad stone is replaced.

The construction method based on this bridge and road support pad includes the following steps:

[0040] S1. The position of the vertical rod 4 is set at the gap between the two corresponding steel bars 5.

[0045] like Figure 1-4 As shown, a bridge support pad stone includes a base surface 1, a frame 2 embedded inside the base surface 1, the frame 2 being positioned corresponding to a support, the frame 2 being made of steel, the inner diameter of the frame 2 being larger than the size of the pad stone 7, the frame 2 being embedded inside the base surface 1, the top surface of the frame 2 being parallel to the base surface 1, a number of insertion holes being opened on the side of the base surface 1 near the inner wall of the frame 2, the insertion holes being filled with reinforcing bars 5, the number of reinforcing bars 5 being several, the number of reinforcing bars 5 being several, evenly distributed inside the frame 2, the number of mesh plates 6 being three, the three mesh plates 6 being linearly arrayed on one side of the reinforcing bars 5, the mesh plates 6 being connected to the reinforcing bars 5 by welding.

[0046] With the above setup, the original pad stone is destroyed and the rubble and steel bars 5 are cleaned up. A new casting frame is then installed according to the position of the frame 2.

[0052] As a preferred technical solution of the present invention, the baffle 8 is composed of four rectangular plates. The shape of the baffle 8 is a rectangular frame. The internal size of the baffle 8 is larger than the combination of the crossbar 3 and the mesh plate 6. The baffle 8 is filled with pad stones 7. The height of the baffle 8 is greater than the height of the pad stones 7. The material of the baffle 8 is a wooden board.
