Embodiment 1

[0046] In this embodiment, a kind of assembled formwork for reinforcing square cross-section columns, such as figure 1, figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As shown, it includes: standard formwork section 1, column top formwork section 2, fastening bolt 3, and connecting plate 4.

[0047] The standard formwork section 1 is a prefabricated lightweight panel with a concave cross section, and three splicing holes 11 are provided at both ends of the notch; a bolt hole 12 is provided in the middle of the back side. The length of the long side of the back side of the standard formwork section 1 is the same as the side length of the reinforced column, and the length of the short sides on both sides is equal to 1 / 2 of the side length of the reinforced column. After two standard formwork sections 1 are matched and docked, they can be formed A square with the same cross-sectional dimensions as the reinforced column.

[0048] The bolt hole 12 is a concave stepp...

Abstract

The invention discloses an assembling type template for reinforcing a square cross-section column and a construction method of the assembling type template. The assembling type template for reinforcing the square cross-section column is characterized by comprising standard template sections, a column top template section, fastening bolts and connecting inserting plates. Upper and lower layers of adjacent templates are in butt joint in a staggered manner, and the template which is used as a part of a reinforcing structure is not dismounted after construction is finished. The template can be prefabricated in a factory, can be used as a column body bearing structure, has the characteristics of light self weight, high strength and good integrality, and is suitable for rebuilding, reinforcing and maintaining old buildings, a construction process can be simplified, working hours are shortened, and the adaptability is high.

Description

Technical field: [0001] The invention relates to an assembled formwork for reinforcing a square-section column and a construction method thereof, belonging to the technical field of civil engineering construction. Background technique: [0002] With the development of the times, people have put forward higher requirements for buildings in terms of safety, applicability and durability, and the original building codes and industry rules have been continuously adjusted and modified. Therefore, how to economically and quickly Strengthening and maintaining old buildings has become a major issue in the current construction field. [0003] The reinforcement of the original columns is one of the main links in the reinforcement and maintenance of old buildings; the reinforcement method is usually to set additional steel bars around the original columns and pour concrete reinforcement layers to increase the stress area of ​​the columns and the column body. Material strength. During ...
