Embodiment Construction
[0051] The invention discloses a method for reinforcing wood structure nodes by adopting angle steel. The angle steel used in the method is a straight plate angle steel, and the two ends of the angle steel are respectively provided with a wing plate for connecting and installing with beams and columns. After the specifications and parameters of the angle steel are determined, the wing plate is connected to the beam and column through self-tapping screws to achieve the purpose of reinforcing the joint. The angle between the wing plates at both ends of the angle steel and the angle steel is 135°. The specific steps are as follows:
[0052] Step 1, measure the rotation angle of the node that needs to be reinforced, and determine whether the node needs to be reinforced, and if it needs to be reinforced, perform step 2;
[0053] The joints of traditional rural wooden houses generally use dovetail tenon and straight tenon joints, so this project mainly studies these two structures....

The invention discloses a method for reinforcing wood structure joints by the use of angle iron. The method comprises following steps: determining whether joints are required to be reinforced; determining the linear rigidity ratio of beams and columns; determining the specification of the angle iron; determining the quantity of self-tapping screws; and determining the length of angle iron flanges. According to the invention, a scientific process for reinforcing the wood joints by the use of the angle iron is established, a mass of investigations and test experimental researches are carried out for determining the process, every parameter of the reinforcing process by the use of the angle iron is scientifically verified and determined, the wood joint reinforcing process is standardized and meets structure and mechanics demands, and the method contributes much to and can promote researches on wood structure anti-seismic and using aspects. Reinforcement materials can be easily obtained. The reinforcing method is simple, scientific and reasonable, and can be easily mastered by farmers. By employing the method, the construction is convenient, and substantial reinforcing effects can be achieved under a condition that the engineering cost is less. The construction can be carried out based on an original structure, and the method can be used together with other reinforcing manners.
Description
technical field [0001] The invention relates to a reinforcement method, in particular to a method for reinforcing nodes with angle steel to increase the overall strength of nodes and buildings. Background technique [0002] Due to historical and economic reasons, wooden structures and brick-wood structures are widely distributed in rural areas of our country, especially in the southwest and northwest high-intensity areas, where there are still a large number of load-bearing buildings with wooden frames. Since these are self-built houses by farmers, the anti-seismic construction measures are not perfect, especially many joints are directly connected with straight tenons, and the anti-seismic performance is poor. Once a high-intensity earthquake occurs, it will pose a serious threat to people's lives and property safety. During the Wenchuan Earthquake, a large number of wooden structure joints in the hardest-hit areas such as Southwestern Sichuan, Northern Sichuan, Southern S...
