Description

Technical Field

[0001] The present invention relates to the technical field related to bridge bearings, and in particular to a bearing with a grouting and exhaust function. Background Art

[0002] As the supporting system of the bridge, the bearing is an important part of the bridge structure. When installing the bearing, the gravity grouting method is usually used to install the bearing on the cushion stone. In actual application, due to the small space, discontinuous grouting, and dense steel bar design, it will be difficult for concrete to fully pass through it. At the same time, it is not easy to vibrate and other reasons. There will be bubbles that are difficult to discharge, or water appears on the bottom of the bearing and causes it to be empty, the concrete molding quality is poor, and a large number of holes appear in the cushion stone after the concrete is poured. These problems may cause local stress concentration in the bearing and cause damage to the bearing or the bearing cushion stone, reducing the service life of the structure, and it is not beautiful. In recent years, with the vigorous development of infrastructure construction, large-span large bridges have continued to increase, and the bridge bearings have continued to increase accordingly. The plane size of the bearings has also continued to increase, and the above problems are particularly prominent.

[0003] With the rapid development of highway and railway bridges in my country, the safety performance of bridges has received more and more attention. If there is a problem of empty space at the support position and the concrete is not dense, then the support position is likely to form a sudden or creeping inward collapse, which will have a negative impact on the upper bridge structure, traffic safety and the stability of the beam itself, and in serious cases will cause major safety accidents. Therefore, effectively solving the problem of concrete density at the existing support installation position to ensure the safety of the bridge structure is a key issue that we urgently need to study and solve.

[0004] In view of the above-mentioned defects, the designer actively carried out research and innovation in order to create a support with grouting and exhaust function to make it more valuable for industrial use. Summary of the invention

[0005] In order to solve the above technical problems, the purpose of the present invention is to provide a support with grouting and exhaust function.

[0006] To achieve the above object, the present invention adopts the following technical solution:

[0007] A support with grouting and exhaust function, comprising, from top to bottom, an upper support plate, a spherical cap structure and a lower support plate;

[0008] The bottom of the lower support plate is evenly provided with a plurality of exhaust pipe grooves along the X-axis direction, and the exhaust pipe grooves are distributed along the Y-axis direction, an exhaust pipe is installed in the exhaust pipe groove, and one side of the exhaust pipe is connected to the pump;

[0009] The exhaust pipe is provided with a plurality of upper side holes for exhausting air on the side close to the upper side, and a plurality of lower side holes for draining water on the side close to the lower side.

[0010] As a further improvement of the present invention, the exhaust pipe groove is a spiral groove, and the spiral portion on the outer side of the exhaust pipe matches the exhaust pipe groove on the outer side.

[0011] As a further improvement of the present invention, the exhaust pipe is installed behind the exhaust pipe groove and spot welded in the exhaust pipe groove.

[0012] As a further improvement of the present invention, the exhaust pipe is a metal exhaust pipe.

[0013] As a further improvement of the present invention, a single-sided exhaust pipe installation gap is provided between the exhaust pipe and the exhaust pipe groove, and the exhaust pipe installation gap is 0.5-2.0 mm.

[0014] As a further improvement of the present invention, one end of the exhaust pipe is located at the center end of the support in the exhaust pipe groove, one end of the exhaust pipe is located at the edge end of the support in the exhaust pipe groove, and one end of the exhaust pipe located at the edge end of the support in the exhaust pipe groove is connected to the pump.

[0015] As a further improvement of the present invention, the diameter of the upper side hole is not greater than 3 mm, and the diameter of the lower side hole is not greater than 4.5 mm.

[0016] As a further improvement of the present invention, the upper side hole and the lower side hole are both round holes or square holes.

[0017] By means of the above scheme, the present invention has at least the following advantages:

[0018] During the grouting process of the support of the present invention, air and water in the mortar on the bottom surface of the support enter the exhaust pipe through a plurality of upper side holes and lower side holes arranged on the exhaust pipe, and at the same time, a pump connected to the exhaust pipe at the edge end of the support is used to pump out the air and water in the pipe. After the grouting is completed, the pump is removed and the port is sealed to ensure that the grouting layer on the bottom surface of the support is uniform and dense, avoid the bottom surface of the support from being emptied, and thus ensure the safety of the structure.

[0041] Preferably, the upper side hole 33 and the lower side hole 34 are both round holes or square holes.

[0042] The working principle of the present invention is briefly described as follows:

[0043] The present invention is a support with grouting exhaust function, specifically including an upper support plate 1, a lower support plate 2 and an exhaust pipe 3. The bottom surface of the lower support plate 2 is provided with a spiral exhaust pipe groove 21. The outer side of the exhaust pipe 3 is also spiral, matching the exhaust pipe groove 2 on the bottom surface of the lower support plate 2, and is placed in the exhaust pipe groove 2 on the bottom surface of the lower support plate 2. The exhaust pipe 3 is then fixed in the spiral groove by spot welding or other methods.

[0044] A plurality of side upper holes 3 with a hole diameter not greater than 3 mm are arranged on the upper side of the spiral metal exhaust pipe 3 . The side upper holes 3 can be round holes or square holes and are mainly used for exhaust.

[0045] A plurality of side lower holes 34 with a hole diameter not greater than 4.5 mm are arranged at the lower side of the spiral metal exhaust pipe 3. The side lower holes 34 can be round holes or square holes and are mainly used for drainage.

[0046] One end of the spiral metal exhaust pipe is located at the center end 31 of the support, and the other end is located at the edge end 32 of the support. This end is connected to a pump 4. During the grouting process, the pump 4 is used to simultaneously exhaust and drain.

[0047] The spiral metal exhaust pipe and the spiral groove at the bottom of the support are provided with an exhaust pipe installation gap 22 of 0.5-2mm on one side to ensure that water or gas can pass through, but mortar cannot pass through. When the support is installed and grouting is performed, the air and water in the mortar on the bottom surface of the support enter the metal exhaust pipe 3 through a plurality of upper side holes 33 and lower side holes 34 arranged on the upper side of the metal exhaust pipe 3. At the same time, the pump 4 connected to the edge end of the metal exhaust pipe 3 at the support is used to pump air and water to promote the discharge of air and water in the mortar. After the mortar automatically overflows and the grouting is completed, the connected pump 4 is removed and the metal exhaust pipe 3 is blocked at the edge end 32 of the support to ensure that the grouting layer on the bottom surface of the support is uniform and dense, and to avoid the phenomenon of hollowing out of the bottom surface of the support, thereby ensuring the safety of the structure.
