The high-strength grouting material enables the round bar and the brick masonry wall to be integrated, and the upper layer brick and the lower layer brick are occluded, so that the aim of improving the shear strength of the brick masonry wall is fulfilled.

Description

Novel brick masonry wall reinforcing technology

Technical Field

The invention belongs to the technical field of earthquake resistance and reinforcement of building structures, and particularly relates to a brick masonry wall reinforcement technology.

Background

For economic reasons, although some civil residences built with a large number of multi-storey masonry structures are gradually dismantled from 50 s in China, a plurality of buildings are still in use, and even up to now, the multi-storey masonry structures are still one of the main forms of rural buildings in China. Along with the increase of service life, all masonry buildings are damaged in different degrees, and due to the brittle characteristics of masonry materials, large construction quality difference and other factors, the shear strength, the tensile strength and the bending strength of masonry structures are low, the overall anti-seismic performance of the structures is poor, and the cracking and the collapse of brick masonry walls under the action of earthquakes are discovered from macroscopic seismic damage and experimental research and mainly due to the fact that the shear strength and the deformation capacity of the walls are insufficient. Under the era background that the standard of brickwork for seismic fortification is gradually improved, the method is necessary to repair and reinforce the unrepaired brick masonry structure and improve the seismic performance of the brick masonry structure.

Bricks and mortar are difficult to replace as materials which are built, so that the domestic reinforcement technology for brick masonry walls comprises a reinforcing mesh mortar surface layer reinforcement method, a reinforced concrete wallboard reinforcement method, a constructional column reinforcement method, a counterfort column method and the like. The existing reinforcement technology is backward in overall level, the construction method and the construction process are complex, the original wall body is seriously damaged, the newly added part and the existing structure cannot work together, the stress performance of the reinforced brick masonry wall is not obviously improved, and the overall reinforcement cost is high. In view of the current situation, a reinforcement technology which is convenient and fast to construct, good in performance after reinforcement and low in cost is urgently needed.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a reinforcement technology of a brick masonry wall, which is convenient and quick to construct, good in performance after reinforcement and low in cost. The reinforcement technology is used for seismic reinforcement of the brick masonry wall in a mode of drilling a hole on the brick masonry wall, putting a precast concrete round bar into the hole, and finally filling high-strength grouting material in a gap between the brick masonry wall and the precast concrete round bar.

The above object of the present invention is achieved by the following technical solutions: the utility model provides a novel brickwork wall reinforcing technique specifically includes brickwork wall, brick, mortar joint, circular entrance to a cave, precast concrete pole, the grout that excels in, brickwork wall is built by laying bricks or stones by a plurality of bricks and is formed, drills at the mortar joint department of upper and lower floor's brick and gets circular entrance to a cave, circular entrance to a cave for lining up the hollow entrance to a cave of wall body, circular entrance to a cave in put into the precast concrete pole, the precast concrete pole forms wholly with the pouring into of the brickwork wall gap department on every side of the precast concrete pole.

Compared with the prior art, the brick masonry wall reinforcing method provided by the invention has the beneficial effects that:

according to the invention, the high-strength grouting material is poured into the gap between the precast concrete round bar and the surrounding brick masonry wall, the round bar and the brick masonry wall are integrated by the high-strength grouting material, and the grouting material realizes mutual occlusion of the upper layer brick and the lower layer brick, so that the shear resistance of the brick masonry wall is improved.

Detailed Description

The present invention will be further described with reference to specific examples, which are only illustrative and not intended to limit the scope of the present invention, and all designs identical or similar to the present invention shall fall within the scope of the present invention.

A novel brickwork wall reinforcing technology is shown in detail in figures 1-4 and comprises brickwork walls 1, bricks 2, mortar joints 3, circular holes 4, precast concrete round bars 5 and high-strength grouting materials 6. The brick masonry wall 1 is formed by building a plurality of bricks 2, and the bricks 2 are similar solid bricks with the size of 240mm multiplied by 115mm multiplied by 53 mm.

And further drilling a circular hole 4 shown in the figure 1 at the mortar joint of the upper layer brick and the lower layer brick of the masonry wall 1, wherein the circle center of the circular hole is positioned at the central line of the horizontal mortar joint, the radius is 1/3-1/2 brick height, and the size of the circular hole is in accordance with the actual construction requirement, so that the construction is convenient.

The drilled round hole 4 is further filled with a precast concrete round bar 5 as shown in fig. 2.

Further pour into high strength grouting material 6 in the gap department of circular entrance to a cave 4 and precast concrete pole 5, grouting material should standardize the configuration as required, realizes through high strength grouting material 6 that precast concrete pole and brick masonry wall form wholly, and grouting material can provide the interlock of upper and lower adjacent layer brick, and then reaches the purpose that promotes brick masonry wall shear strength, and the in-process should prevent the not closely knit precast concrete pole that leads to of slip out the destruction of entrance to a cave when the atress.

The invention is not limited to the above-described preferred embodiments, but may be modified or changed by those skilled in the art, and any modification, equivalent replacement, or improvement made within the spirit and principle of the invention should be included in the protection scope of the invention.
