Detailed Description
As shown in figure 1, the suspension device for testing the heat resistance of the asphalt waterproof coiled material consists of a chassis 1, a bracket 2 and a sample clamp 3.
The material of chassis 1 is the stainless steel metal disc, and the shape is the rectangle, is used for fixed bolster 2 on the one hand, plays a support role, and on the other hand is used for collecting the pitch that pitch waterproofing membrane drips under high temperature.
As shown in figure 1, the support 2 comprises left and right longitudinal supports 2-1, and a transverse support 2-2 is connected between the two longitudinal supports 2-1. The longitudinal support 2-1 and the transverse support 2-2 are both made of metal iron materials.
As shown in figures 2-4, the longitudinal supports 2-1 on each side are obliquely arranged in a front-back two-piece mode to form a triangular structure, and the triangular structure is used for guaranteeing the stability of the support. The upper ends of the two longitudinal supports 2-1 are detachably connected with the connector 2-3 through threads, the lower ends of the two longitudinal supports 2-1 are horizontally bent and are respectively sleeved with the sleeves at the upper ends of the sliding blocks 2-4, the magnet sleeves 2-9 can be sleeved after the sleeve connection, the inner walls of the magnet sleeves 2-9 are fixed with the horizontal section of the longitudinal supports 2-1 through magnetic adsorption, and the end faces of the magnet sleeves 2-9 are fixed with the sliding blocks 2-4 through magnetic adsorption. In order to avoid relative rotation of the longitudinal support 2-1, square head holes are formed in the sleeve at the upper end of the sliding block 2-4 and the end head of the longitudinal support 2-1, and the corresponding magnet sleeve 2-9 can be inserted into the square head holes through a plug. And the lower end of the sliding block 2-4 is arranged on the sliding rail 2-5 in a sliding way and is locked by a bolt at one side.
As shown in fig. 3, and the transverse supports 2-2 are used for hanging asphalt waterproof coiled material test pieces, so that effective isolation between the test pieces is ensured. The longitudinal support 2-1 comprises a forward rotation threaded rod 2-6, a reverse rotation threaded rod 2-7 and a threaded sleeve 2-8, wherein the reverse side of the forward rotation threaded rod 2-6 and the reverse rotation threaded rod 2-7 is hinged with the joint 2-3, and the opposite sides of the forward rotation threaded rod 2-6 and the reverse rotation threaded rod 2-7 are in threaded connection with the threaded sleeve 2-8. Because the forward-rotation threaded rods 2-6 and the reverse-rotation threaded rods 2-7 have opposite rotation directions, the forward-rotation threaded rods 2-6 and the reverse-rotation threaded rods 2-7 are relatively close to or far away from each other when the thread sleeves 2-8 are rotated. Therefore, the overall length of the transverse support 2-2 can be adjusted, and different numbers of asphalt waterproof coiled material test pieces can be hung.
The sample clamp 3 is a stainless steel sample clamp with the width of 120mm, clamping parts on two sides are flat, and the clamped test piece can be vertically suspended.
