Rod and multilayer boards combined T-shaped beam of bottom-chord built-in reinforcement steel bar and manufacturing method of T-shaped beam

Abstract

The invention discloses a rod and multilayer boards combined T-shaped beam of a bottom-chord built-in reinforcement steel bar and a manufacturing method of the T-shaped beam, belonging to the field of constructional engineering. Two semi-cylindrical rods with grooves in hole cores and a tensile reinforcement steel bar form a circular bottom-chord rod of the built-in reinforcement steel bar by bamboo nails; a rod with arc-shaped slots in upper and lower ends is arranged between the circular bottom-chord rod and the semi-cylindrical rods which are parallel to each other, and is vertical to the circular bottom-chord rod and the semi-cylindrical rods; the arc-shaped slots in the two ends respectively contact the circular outer surfaces of the circular bottom-chord rod and the semi-cylindrical rods, and are connected together by the bamboo nails; a layer of multilayer boards is fixed on each of the lower side of the bottom-chord rod of the formed part and the left and right sides of the formed part; another rod is arranged on each of the outer sides of the left and right multilayer boards of the rod; the three rods are connected by a connecting reinforcement steel bar to form a flange of the T-shaped beam; and the layer of multilayer boards is fixed on the outer surface of the exposed rod to form the rod and multilayer boards combined T-shaped beam of the bottom-chord built-in reinforcement steel bar. According to the rod and multilayer boards combined T-shaped beam of the bottom-chord built-in reinforcement steel bar and the manufacturing method of the T-shaped beam provided by the invention, the rods resources are utilized to the greatest extent; the resource waste is reduced; the yield of construction waste is reduced; the manufacturing process is simple; and the construction is convenient.

Description

Technical field: [0001] The invention relates to a T-shaped beam combined with a small log and a multi-layer plate with a built-in steel bar in the lower chord by using the processed small log through bamboo nails, assembling and other processes, and then combining it with a multi-layer board, belonging to the construction industry. field of engineering technology. Background technique: [0002] With the development of the timber harvesting industry and the thinning of fast-growing timber such as fir, poplar, and fir in their young stages, the proportion of small round logs has increased significantly. Due to the shortcomings of small diameter, unstable material, and high collection and transportation costs, small round logs are not fully utilized, and are even discarded as waste. With the rapid development of society, people realize the sharp reduction of global resources, and have begun to study the application of small logs. Some existing small round logs are used to ma...

AI Technical Summary

Problems solved by technology

At present, some small round logs are used to make blockboard cores, integrated boards, etc., but the utilization rate is low and the production cost is high, so they cannot be used alone in beams with high strength requirements
