Adjustable sliding block inclined beam steel frame canopy guard structure for bricked residence and construction method thereof

Abstract

The invention relates to an adjustable sliding block inclined beam steel frame canopy guard structure of a bricked residence and a construction method of the adjustable sliding block inclined beam steel frame canopy guard structure of the bricked residence. The adjustable sliding block inclined beam steel frame canopy guard structure is arranged in the bricked residence with a flush gable roof erected by purlins and comprises externally-added longitudinal steel beams, externally-added horizontal steel beams, roof truss beams, externally-added inclined steel beams, adjustable sliding blocks, externally-added steel posts, transverse supports and inclined supports. The two externally-added inclined steel beams are arranged in a butt joint mode in a reversed-V shape. Top surface kidney-shaped holes are formed in the upper surface of each inclined steel beam at intervals so that the adjustable sliding blocks can be installed. Side face kidney-shaped holes are formed in the two sides of each inclined steel beam so that the adjustable sliding blocks can be fixed. The bottom ends of the two inclined steel beams are fixedly connected with one roof truss beam, an A-shaped inclined beam steel frame is formed through the two inclined steel beams and the roof truss beam, and the A-shaped inclined beam steel frame is supported on the externally-added longitudinal steel beams. The adjustable sliding blocks are implanted into the top face kidney-shaped holes of the inclined steel beams, after the erection positions of the purlins on the adjustable sliding blocks are determined, the purlins are fastened through bolts and nuts, and the adjustable sliding blocks are fixed on the inclined steel beams.

Description

technical field [0001] The invention relates to a reinforcement reconstruction measure, in particular to an adjustable sliding block slanted beam steel frame roof protection structure for a masonry house and a construction method thereof, belonging to the technical field of seismic reinforcement. Background technique [0002] All previous major earthquakes in my country have caused heavy damage to rural areas, and most of the houses have been seen to collapse as a whole. The Gansu earthquake, Qinghai Yushu and Wenchuan earthquakes all have one thing in common, that is, residential houses in areas with poor economic conditions are the weakest against earthquakes. Our country is a country with frequent earthquakes, and China is a big agricultural country. The population living in rural areas is 670 million, accounting for 50.32% of the national population. Among them, there are 150 million impoverished people. Most of the houses of these people cannot withstand earthquakes o...

Problems solved by technology

[0003] In order to overcome the above-mentioned problems, the present invention proposes an adjustable sliding block inclined beam steel frame roof protection structure and its construction method for a masonry house. The frame is transmitted to the external column, and then to the foundation, changing the force transmission mode of the original structure, and transforming the masonry structure with poor seismic performance into a mixed structure mainly relying on the external adjustable sliding block oblique beam steel frame and masonry. Fundamentally solve the problem of poor seismic performance of houses in remote areas of our country, and serious loss of personnel and property caused by earthquakes
