Description

Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to a fixing and protecting device for a vibration damping pad on a pile foundation top. Background Art

[0002] Buildings (structures) within the operating range of the subway are often affected by the vibration of the buildings (structures) during the operation of the subway. Therefore, vibration reduction and isolation measures are often taken at the top of the foundation in the project to ensure the comfort of the building (structure) during use. Rubber pads are often applied to the top of the foundation to achieve vibration reduction and isolation. During the placement of the rubber pads, fixing measures should be adopted to avoid dislocation or deflection of the rubber pads during the construction process, thereby affecting the effect of vibration reduction and isolation.

[0003] At present, the installation of building vibration isolation bearings often uses pre-buried anchor bolt steel plates on the top of the foundation, and then fastens the vibration isolation bearings to the pre-buried steel plates with bolts. This operation requires precise measurement and positioning throughout the installation process, and requires large equipment for hoisting. The operation accuracy requirements are strict, and it is difficult to correct any operational errors. For this reason, it is very meaningful to study a foundation top vibration isolation pad protection device with simple structure, low cost, and convenient construction in combination with the actual situation on site.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a fixing and protecting device for a vibration-damping pad on a pile foundation top, comprising a base plate, a fixing portion and a limiting portion; the fixing portion is fixedly connected to the base plate, and the fixing portion is adapted to the shape of the base plate; the limiting portion is arranged on the periphery of the fixing portion to limit the movement of the fixing portion and the bottom; the fixing portion is a mesh structure formed by a skeleton staggered in a longitudinal and transverse direction.

[0006] A further improvement is that the shape of the bottom plate is the same as that of the pile foundation; the diameter of the bottom plate is 10-30 mm larger than the diameter of the pile foundation; the thickness of the bottom plate is 3-8 mm. The shape of the bottom plate can be round or square.

[0007] A further improvement is that the diameter of the bottom plate is 20 mm larger than the diameter of the pile foundation; and the thickness of the bottom plate is 5 mm.

[0008] A further improvement is that the bottom plate is provided with an opening in the middle for the prestressed beam in the pile foundation to pass through. The size of the opening in the middle of the bottom plate is adapted to the size of the prestressed beam in the pile foundation.

[0009] A further improvement is that the spacing between the vertically and horizontally staggered frames of the fixing part is 80-120 mm; and the diameter of the frame selected for the fixing part is 10-30 mm.

[0010] A further improvement is that the spacing between the vertically and horizontally staggered frames of the fixing part is 100 mm; and the diameter of the frame selected for the fixing part is 20 mm.

[0011] A further improvement is that the spacings between the frames of the fixing part that are staggered vertically and horizontally are all the same.

[0013] A further improvement is that the angle steel has a size of 50x50x5 and a length of 100-130 mm.

[0014] A further improvement is that the angle steel is 120 mm.

[0016] A further improvement is that the number of the limiting parts is at least 3.

[0017] A further improvement is that the material used for the frame of the fixing part is steel bars, and the diameter of the steel bars is 5-15 mm.

[0018] A further improvement is that the diameter of the steel bar is 10 mm.

[0019] After the rubber shock-absorbing pad (the diameter of the shock-absorbing pad is the same as the diameter of the pile foundation) is installed, the fixed protection device obtained by the utility model is placed on the upper part of the shock-absorbing pad. The mesh structure formed by the skeleton and the bottom plate on the top of the fixed protection device limit the vertical movement of the shock-absorbing pad, and the limiting parts around it limit the lateral movement of the rubber shock-absorbing pad. At the same time, the fixing device of the utility model has a certain rigidity, so the disturbance in the construction project will not cause the dislocation and deflection of the shock-absorbing pad, thereby ensuring the accuracy of the position of the rubber shock-absorbing pad.
