Problems solved by technology

The construction technology and method of this method are relatively complicated, and the improvement of the seismic performance after reinforcement is limited, and buttress columns are added outside the original building, which seriously affects the appearance of the original building and looks too bulky. In addition, when the wall is thicker, It will also increase the construction difficulty of grooving and reinforcement

Embodiment 1

[0023] Follow the technical scheme of the present invention, such as figure 1 As shown, this embodiment is a six-storey brick-concrete office building with a brick wall thickness of 370 mm, and structural columns are added at the intersection of vertical and horizontal walls in the middle of the building. The surface of the wall at the junction of the vertical and horizontal walls extends longitudinally and transversely by 1 / 2 brick length, i.e. 120mm, to determine the size range of the pre-installed structural columns, such as figure 1 As shown, then cut and remove the original building surface mortar and 60mm thick brick masonry wall 1 at the structural column, and finally set up the formwork on the outside of the wall, the formwork is flush with the original wall surface, and pour high ductility fiber concrete 2 after curing 2 - After 3 days, the formwork was removed, and the high-ductile fiber concrete poured was finally integrated with the original wall structure.

Embodiment 2

[0033] Such as figure 2 As shown, this embodiment is a six-storey brick-concrete office building with a brick wall thickness of 370mm, and structural columns are added at the intersection of vertical and horizontal walls at the corners of the building. The wall surface at the intersection of vertical and horizontal walls extends 120mm longitudinally and horizontally respectively, and the size range of pre-installed structural columns is determined, such as figure 2 shown. The difference between this example and embodiment 1 is that the additional construction column is a corner column, and the shape and size of the additional construction column are different, and other construction procedures are the same as embodiment 1.

[0034] The present invention not only improves the shear strength and anti-seismic ability of the brick masonry wall, but also improves its integrity by utilizing the advantages of the mechanical properties of the high-ductility fiber concrete and the g...

Abstract

The invention discloses a construction method of a high elongation concrete embedded constructional column. The method is applicable to a brick masonry structure with wall thickness larger than 240mm. During construction, firstly the size of a pre-added constructional column at a connection position of a vertical wall and a transverse wall of the brick masonry structure is determined, then surface mortar of an original building at the pre-added constructional column position and a part of brick masonry wall are removed, and finally a formwork is built and high elongation fiber concrete is poured. By means of mechanical performance advantages of the high elongation fiber concrete and good bonding performance between the high elongation fiber concrete and the brick masonry, a constructional column is added to greatly improve shear capacity, avoid brittle failure and greatly improve anti-seismic performance of the brick masonry wall. The method has the advantages that reinforcing effect is good, construction process is simple, and appearance of the original building after reinforcing is not affected.

Description

technical field [0001] The invention belongs to the technical field of anti-seismic and reinforcement of building structures, and in particular relates to a construction method of a high-ductility concrete embedded structural column suitable for a brick masonry structure with a wall thickness greater than 240 mm. Background technique [0002] At present, the commonly used seismic strengthening method for masonry structures is to add concrete buttress columns. The construction technology and method of this method are relatively complicated, and the improvement of the seismic performance after reinforcement is limited, and buttress columns are added outside the original building, which seriously affects the appearance of the original building and looks too bulky. In addition, when the wall is thicker, It will also increase the construction difficulty of slotting and reinforcement. Contents of the invention [0003] The object of the present invention is to provide a kind of...
