Problems solved by technology
However, due to the excessive reliance of the section method on welding construction, this has caused a series of inevitable problems: it is difficult to avoid complicated construction operations such as overhead welding when reinforcing the existing structure under load; When the round steel rods are welded under load, the strength of the heat-affected zone of the weld will drop sharply, which will directly affect the safety of the reinforcement construction; the residual stress generated by the welding operation will also bring safety hazards to the use of the reinforced structure

Embodiment 1
[0030] Such as Figure 1~6 As shown, an assembled mortise and tenon reinforcement system for H-shaped steel includes a reinforced bottom plate 2, an L-shaped inner plate 3, and an L-shaped outer plate 4. The reinforced bottom plate 2 is close to the web of the H-shaped steel to be reinforced. There is a dovetail-shaped tenon, the reinforced bottom plate 2 and the L-shaped inner plate 3 are connected by a dovetail tenon, and the L-shaped inner plate 3 and the L-shaped outer plate 4 are respectively arranged on the inner and outer sides of the H-shaped steel flange to be reinforced and connected by bolts. Two adjacent L-shaped outer plates 4 on the outer side are connected by bolts, and one piece of H-shaped steel to be reinforced requires two reinforced bottom plates, four L-shaped inner plates 3 and four L-shaped outer plates 4 .
[0031] The reinforced bottom plate 2 and the two L-shaped inner plates 3 on the same side of the web can slide along the height direction of the we...

The invention discloses an assembled mortise and tenon reinforcement system for H-shaped steel, which comprises a reinforced bottom plate, an L-shaped inner plate and an L-shaped outer plate, the reinforced bottom plate is closely attached to the web plate of the H-shaped steel to be reinforced, and a dovetail shape is arranged on the outer side of the bottom plate The tenon, reinforced bottom plate and L-shaped inner plate are connected by dovetail tenons. The L-shaped inner plate and the L-shaped outer plate are respectively arranged on the inner and outer sides of the H-shaped steel flange to be reinforced and connected by bolts. Two adjacent L-shaped plates on the outer side of the flange The outer plates are connected by bolts, and one H-shaped steel to be reinforced requires two reinforced bottom plates, four L-shaped inner plates and four L-shaped outer plates. The invention has the advantages of fully assembled construction, simple and high-efficiency operation, obvious reinforcement effect and the like. It can be widely used in the design or reinforcement of H-shaped steel components. The reinforcement method can achieve the purpose of improving the bearing capacity of the rods by suppressing the lateral deformation of the components.
Description
technical field [0001] The invention relates to an assembled mortise and tenon reinforcement system for H-shaped steel and an assembly method thereof, belonging to the technical field of assembled structures in engineering. Background technique [0002] Steel is the most widely used metal building material in modern structural engineering. In production and construction, after the steel structure has been tested and verified for reliability, if it is deemed that it does not meet the requirements, it must be reinforced. When the steel structure has the following conditions, it needs to be strengthened and transformed: [0003] (a) Increased load due to changes in service conditions; [0004] (b) due to shortcomings in the design or construction work, the load-bearing capacity of the structure or its parts does not meet the design requirements; [0005] (c) The structure or joints are weakened due to wear, corrosion, and the load-bearing capacity of the structure or its part...
