[0003] Because the bearing surface of the rock is uneven and even has a difference in height, in the process of laying the rail steel, in order to ensure that the rail steel is at the same level, it is necessary to support the bottom of the rail steel. Currently, the support for the bottom of the rail steel The pad mainly adopts the method of stacking multiple wooden blocks and chasing and squeezing multiple small wooden wedges. This method is not only difficult to adjust the height, but also the stacked wooden blocks will vibrate, dislocate or even collapse due to the vibration of the rail steel. In addition, ready-made wood blocks are not easy to obtain and store, and it is not environmentally friendly, so the reuse rate of wood blocks is very low

Embodiment Construction
[0019] The applicant of this patent takes Minnan Construction Engineering Group Headquarters Building as the specific implementation location, and provides the following specific examples:
[0020] Such as figure 1 , figure 2 As shown, a laminated rail steel backing device used in conjunction with a rock foundation cutting machine is composed of a plurality of flat support plates 1, a plurality of half-side hole support plates 2, a plurality of double-sided hole support plates 3, and a plurality of long The foot nail 6, a plurality of short foot nails 7, and a plurality of cross-shaped buckle nails 8 are characterized in that,
[0021] There are cross-shaped buttonholes 4 around the multi-piece flat support plate 1, the multi-piece half-side hole support plate 2, and the multi-piece double-sided hole support plate 3;
[0022] A plurality of double-sided hole support plates 3 are stacked together, and each double-sided hole support plate 3 is provided with a plurality of fir...

Disclosed is a laminated type rail steel cushioning device used in cooperation with a rock foundation cutting machine. Cross buckling holes are formed in the periphery of a plurality of flat supporting plates, the periphery of a plurality of hemi-side hole supporting plates and the periphery of a plurality of double-side hole supporting plates; the double-side hole supporting plates are laminated together; the left side and the right side of each double-side hole supporting plate are each provided with a plurality of first nail holes; the hemi-side hole supporting plates are laminated together and are laminated over the double-side hole supporting plates; a plurality of second nail holes are formed in one side of each hemi-side hole supporting plate; the flat supporting plates are laminated together and are laminated over the hemi-side hole supporting plates; the top faces of the flat supporting plates are horizontally cushioned at the bottom of rail steel; long shackles can be strung into the first nail holes and are strung into the second nail holes upwards; short shackles can be strung into the first nail holes; cross buckling nails can be put into the cross buckling holes respectively from top to bottom. The laminated type rail steel cushioning device has the advantages of being novel in structure, easy and convenient to operate, flexible in height adjustment, high in cushioning stability and long in service life.
Description
technical field [0001] The invention belongs to the field of building construction equipment, and relates to a laminated rail steel backing device used in conjunction with a rock foundation cutting machine. Background technique [0002] The main body of the building needs to excavate the foundation before the construction. During the downward excavation of the foundation, it will be encountered that the foundation in some places is completely rock, especially granite. In this case, it is necessary to use the mine cutting machine To cut the rock longitudinally, it is first necessary to lay and fix the rail steel on the rock, so that the mine cutting machine can move back and forth along the rail steel to achieve the purpose of long-line cutting. [0003] Because the rock load-bearing surface is uneven and even has a difference in height, in the process of laying the rail steel, in order to ensure that the rail steel is at the same level, it is necessary to support the bottom ...
