Structure for reinforcing masonry structure through flat steel tie rods and adopting angle steel base plates and ring beam constructional columns for connecting end parts and construction method

Abstract

The invention relates to a structure for reinforcing a masonry structure through flat steel tie rods and adopting angle steel base plates, ring beams and constructional columns for connecting end parts and a construction method. The structure comprises the flat steel tie rods, the angle steel base plates, tie bolts, grooves, the ring beams and the constructional columns. The flat steel tie rods are arranged in wall surface ash grooves which cling to the horizontal position of the wall surface and at the lower side of a floor slab or a roof panel; the flat steel tie rods are made of Q235B flat steel with the width of 100 mm and the thickness of 6 mm; tie bases are formed by welding tie plates, stiffening ribs and the flat steel tie rods; the grooves are ash removing grooves with the size of 180 mm* 25 mm, and the grooves are operation spaces facilitating connection and tensioning between the flat steel tie rods and the tie bases; the flat steel tie rods are connected with an original structure outer wall through the angle steel base plates and are poured together with the ring beams and the constructional columns; and two oval mounting holes are formed in each angle steel base plate, and the angle steel base plates are fixedly connected with the tie bases at the inner sides of the original structure outer wall through the tie bolts.

Description

technical field [0001] The invention relates to a flat steel tie rod reinforced masonry structure end which is connected with an angle steel backing plate and a ring beam structural column and a construction method thereof, which belongs to the field of comprehensive transformation of seismic reinforcement. Background technique [0002] In the seismic reinforcement of existing masonry structures, the traditional reinforcement methods are mostly wet work of cast-in-place concrete, which requires supporting formwork and demolition, and the construction period is long. Sometimes it is necessary to increase the thickness of the wall and reduce the usable area of ​​the building. It needs to be demolished, and the disadvantages such as making up after construction have increased the amount of work and construction costs. At the same time, due to the great influence of the environment and the site, the selection and use of traditional reinforcement methods are limited. Therefore, a...

[0002] In the seismic reinforcement of existing masonry structures, the traditional reinforcement methods are mostly wet work of cast-in-place concrete, which requires supporting formwork and demolition, and the construction period is long. Sometimes it is necessary to increase the thickness of the wall and reduce the usable area of ​​the building. It needs to be dismantled and repaired after construction, etc., which increases the amount of work and construction costs.

At the same time, due to the great influence of the environment and the site, the selection and use of traditional reinforcement methods are limited. Therefore, a new and reasonable reinforcement method is studied - using flat steel tie rods to strengthen the end of the masonry structure. Angle steel backing plate and ring beam structure column to connect
