Construction process of concrete-stone combined railing

Abstract

The invention relates to a construction process of a concrete-stone combined railing, and belongs to the field of urban bridge guardrails. The railing comprises anchoring stress ribs, a breast board,a handrail, a railing base, a column head and a stand column, an upper tenon and a lower tenon are arranged at the upper end and the lower end of the breast board respectively, an upper mortise is formed in the upper end of the stand column, a lower mortise is formed in the railing base, and the left end and the right end of the breast board and the left end and the right end of the handrail are in joggle joint with the stand column. The lower end of the stand column and the lower tenon are installed in the lower mortise, the handrail is installed on the upper tenon, the column head is installed in the upper mortise, the anchoring stress ribs are arranged in the stand column, and one ends of the anchoring stress ribs are located in the lower mortise. According to the combined railing, thedefects of an existing stone railing are overcome from the aspects of structural construction, connecting modes, construction technologies and the like, the concrete-stone railing which is higher in bearing capacity, more reliable in connection, better in integrity and convenient and fast to construct is provided, and the combined railing has great application and popularization value.

Description

technical field [0001] The invention relates to a construction technique for a concrete-stone composite railing, which belongs to the field of urban bridge guardrails. Background technique [0002] Stone railings are widely used in small and medium-span bridges in cities because of their elegant appearance, thick and durable structure, and strong expressive force. The stone railing is mainly composed of columns and handrails. The lateral force acts on the handrails. The handrails are used as force-transmitting components to transfer the load to the columns. All lateral forces are ultimately borne by the columns. The bending bearing capacity of the stone itself is small, and it is difficult to resist a large lateral force. Designers often increase the cross-sectional size of the railing to meet the requirements of the code for bearing capacity. This approach not only resulted in the compression of the net width of the sidewalk and the increase in the amount of materials used...

AI Technical Summary

Problems solved by technology

The safety of the railing mainly depends on the reliability and durability of the connection between the mortise and tenon, and the mortise and tenon connection has high requirements for construction technology and workers' skills. As time goes by, the railing is prone to loose tenon and mortar Phenomena such as falling off have had adverse effects on operation management and structural safety
