Sliding formwork supporting device for brick wall reinforcement and construction method

Abstract

The invention provides a sliding formwork supporting device for brick wall reinforcement and a construction method. A supporting steel frame is connected with a floor on one side of a brick wall; a sliding rail is arranged on the side, close to the brick wall, of the supporting steel frame; the sliding rail is parallel to the brick wall; a formwork is arranged at the to-be-reinforced position on one side of the brick wall; one end of a supporting steel rod is connected with a pulley; the pulley is arranged on the sliding rail; the other end of the supporting steel rod is connected to the formwork; the formwork slides up and down along the sliding rail by utilizing the characteristics of the sliding formwork supporting device; the ground clearance of the formwork is controlled; and then the brick wall is subjected to layered formwork supporting reinforcement. The brick wall reinforcement requirement can be met; construction is convenient and fast; the brick wall is not damaged, and the historical building protection requirement is met; steel pipes, square timbers, fasteners and other reinforcement materials are not needed, the formwork supporting cost is low, and economic benefits are high; and the construction site environment limitation is small. Compared with a traditional formwork supporting mode, the sliding formwork supporting device is easy and convenient to use, the brick wall is not damaged, and the reinforcement efficiency and the reinforcement quality are improved.

Description

technical field [0001] The invention relates to a sliding formwork support device and a construction method for brick wall reinforcement. Background technique [0002] In many famous historical and cultural cities in my country, there are a large number of historical buildings that urgently need to be repaired, remodeled and reused. Since modern times, the repair and reuse of historically protected buildings has become a hot spot in academic research. Most of the existing historically protected buildings use brick walls as the main vertical load-bearing components. These masonry load-bearing walls have accumulated varying degrees of damage during long-term service, resulting in varying degrees of degradation in their performance. At the same time, the early design and construction methods of most historical buildings are quite different from the current design code concepts, and their bearing capacity and earthquake resistance need to be considered when repairing and updati...

Problems solved by technology

Among them, the double-drawing screw formwork support technology is to pass the screw through the wall, and fix the formwork on both sides of the screw with square wood, steel pipe, mountain clip, nut and other fasteners to form a formwork supporting form of double-drawing. The double-drawing screw will meet the brick wall. Cause damage, not suitable for some buildings with high protection requirements

The single-sided integral formwork fixes the formwork by means of diagonal braces. In actual engineering, the reinforcement height of the single-sided integral formwork is high, and the formwork is subject to large lateral pressure. The formwork system is easy to deform and leak, and the reinforcement quality is difficult to guarantee.
