Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The utility model provides a floor pad roof beam for EMUs, including lower part section bar 1 and upper portion section bar 2, lower part section bar 1 and upper portion section bar 2 all are the shape of U font, the upper end back-off of lower part section bar 1 has upper portion section bar 2, rubber column 7 has all been placed between two medial surfaces of the bottom surface of upper portion section bar 2 and two lateral surfaces of lower part section bar 1, on two lateral surfaces of lower part section bar 1 and the below that lies in two rubber column 7 has all welded protruding piece, just rubber column 7 all closely laminates with two lateral surfaces of lower part section bar 1, two medial surfaces of upper portion section bar 2 and protruding piece, rubber pad 4 has been placed to the upper surface of upper portion section bar 2, the surface of rubber pad 4 and upper portion section bar 2 is provided with a pair of perforation 11 and trapezoidal hole 10 respectively, just it has been interpenetrated between perforation 11 and trapezoidal hole 10 type countersunk head self-plugging rivet 5, through setting up lower part section bar 1 and upper portion section bar 2 that is the U font, upper portion section bar 2 can back-off the back-off on lower part section bar 1, and upper portion section bar 2 just the atress section bar 2 and lower part 2 belongs to wrap up the mode each other, and the clearance between 7, and also can not only take place the atress portion of rubber column and also can all take place the atress big resistance, and all receive the atress big enough to push down when the atress 2, and can all the atress section bar 2, and take place the atress, and can all the atress section bar 2.

Specifically, the two side walls of the lower section bar 1 incline towards each other, the two side walls of the upper section bar 2 incline towards opposite directions, the distance between the side walls of the lower section bar 1 and the side walls of the upper section bar 2 is just equal to the thickness of the rubber columns 7, the two rubber columns 7 are convenient to place, and the arrangement is more beneficial to tight connection under the matching of the rubber columns 7, so that the inclination is not easy to occur.

Specifically, the bottom surface of upper portion section bar 2 just is located and is provided with stiffening plate 3 between the both sides wall of lower part section bar 1, just stiffening plate 3 passes through enclosed type countersunk head self-plugging rivet 5 to be fixed in the bottom surface of upper portion section bar 2, sets up stiffening plate 3 and can consolidate enclosed type countersunk head self-plugging rivet 5 and upper portion section bar 2's firm connection.

Specifically, the adjusting pad 6 is placed on the upper surface of the rubber pad 4, and the cross section of the adjusting pad 6 is the same as that of the rubber pad 4, so that the rubber pad 4 is prevented from being affected by the excessive downward pressing of the pile driver.
