Abstract: A waterproof and electricity-insulating support structure for solar panels includes a base frame having a top portion with two side portions disposed at two sides of the top portion. Each of the side portions connects with a bottom portion to be fixed on a steel frame forming a roof. A fastening member is fixed to the top portion of the base frame to form an assembling space for solar panels therebetween. A plurality of rubber strips for waterproofing and insulating from electricity are disposed between the side portions and the solar panels and between the fastening member and the solar panels.

Abstract: A ladder made by plastic material includes a first ladder unit which includes two side rails with a plurality of rungs integrally connected between the two side rails. A head step is integrally connected to two respective top ends of the two side rails. The first ladder unit includes an open first side and a closed second side. Each of the rungs includes a latitude rib and altitude ribs connected to an inner periphery of the open first side so as to define a plurality of chambers in the open first side of each rung, and each side rail includes two sidewalls and a plurality of latitude ribs connected between the two sidewalls so as to define chambers separated by the latitude ribs. Each rung has an anti-slip top surface. A second ladder unit can be pivotably connected to the first ladder unit at two respective head steps.
Abstract translation: 由塑料材料制成的梯子包括第一梯形单元，该梯形单元包括两个侧轨，多个梯级一体地连接在两个侧轨之间。 头部台阶一体地连接到两个侧轨的两个相应的顶端。 第一梯形单元包括打开的第一侧和闭合的第二侧。 每个梯级包括与开放的第一侧的内周边连接的纬度肋和高度肋，以便在每个梯级的敞开的第一侧中限定多个室，并且每个侧轨包括两个侧壁和多个纬度 肋连接在两个侧壁之间，以便限定由纬度肋分隔的室。 每个梯级都有防滑顶面。 第二梯形单元可以在两个相应的头部步骤可枢转地连接到第一梯形单元。
