Abstract

The invention discloses a connection board for combination stair stand, comprising an elongated main body which comprises two fixed connection holes along the length direction, characterized in that at least one of the fixed connection holes is a fixed connection groove spread along the length direction. When the connection board connecting together to be a stair stand, a connection bar can move in the fixed connection groove via installing the connection bar in the relative position of the connection groove with no need to bend the connection board and adjusting the direction of height and width conveniently. The connection board not only has a simple structure and applies in large scale working, but also is easy to assemble.

Description

technical field [0001] The invention relates to a combined staircase, in particular to a connecting plate of a combined staircase support and a combined staircase support. Background technique [0002] As a building component, the existing stairs mainly include wooden stairs, steel stairs and reinforced concrete stairs. Since these stairs need to be further constructed on site when they are manufactured, they occupy a large area, have a long construction period, and are bulky in appearance. After the staircase is completed, it cannot be moved as a whole. For this reason, people have invented the combined staircase that can be easily disassembled and installed. The Chinese utility model patent No. 03252951.1 authorized by the announcement on October 6, 2004 discloses an assembleable combined staircase, wherein the side boards of the stairs are composed of several connecting boards, and the two sides of each stair tread have the same connection up and down. The boards are cr...
