Detailed Description
The utility model is further described below in connection with specific embodiments.
Example 1
As shown in fig. 1, the embodiment mainly shows a carbon fiber cloth reinforcement mode of a cross-shaped mortise-tenon joint.
The wood beam 1 is in mortise-tenon connection in a transverse mode and a longitudinal mode, the distance between two end points of the wood beam 1 and the node is longer, and the carbon fiber cloth 2 cannot be reinforced through the end points of the wood beam 1.
Before the mounting, firstly filling special glue for the carbon fiber cloth 2 into the mortise and tenon structure gaps in the cross joints, and brushing corresponding glue on the positions where the carbon fibers 2 are required to be mounted.
And then, in the vertical parallel direction of the wood beam 1, the strip-shaped carbon fiber cloth 2 is attached through the joints, the carbon fiber cloth 2 is bent when passing through the mortise and tenon joint, the attachment is continuously carried out along the right-angle direction of the cross joint, and the four split L-shaped structures are formed at the four right-angle positions of the cross joint.
The carbon fiber cloth 2 in the complete parallel direction is continuously attached, the annular reinforcing part 3 is the carbon fiber cloth 2, the carbon fiber cloth 2 in the parallel direction is covered at the position close to the mortise and tenon joint for surrounding attachment, and the attachment stability of the carbon fiber cloth 2 in the parallel direction and the strength of the mortise and tenon joint are further enhanced.
The structure of the reinforcement can be further reinforced in the direction of the object of the mortise and tenon joint in an X-shaped manner, and the reinforcement mode is not expressed in fig. 1 because of the need of displaying the mounting mode of the foundation, but the reinforcement can be further reinforced according to specific requirements in practical application.
Example 2
As shown in fig. 2, this embodiment is a carbon fiber cloth reinforcement method for T-shaped mortise and tenon joints.
The wood beams 1 are connected by mortise and tenon in a transverse and longitudinal manner, which is different from the embodiment 1 in that the connection mode of the embodiment is that the end point of one wood beam 1 is connected by mortise and tenon with the middle position of the other wood beam, and two connection conditions of fig. 2 and 3 can be generated according to whether the wood beam 1 inserted by the end point at the mortise and tenon joint penetrates through the other wood beam 1.
As shown in fig. 2, when the longitudinal wooden beams 1 are connected with the transverse wooden beams 1, a part of the ends of the longitudinal wooden beams 1 protrude from the outer surface of the transverse wooden beams 1. Under the T-shaped nodes, the long edges of the three wood beams 1 are attached by two carbon fiber cloth 2 with L-shaped structures in the same manner as in the embodiment 1, and glue in the embodiment 1 is poured into joints of the mortise and tenon joints.
The protruding part above the T-shaped node is reinforced by adopting a whole piece of carbon fiber cloth 2, the protruding end point of the protruding longitudinal wood beam 1 is directly bent from the parallel direction of the transverse wood beam 1, the protruding end point returns to the parallel direction of the transverse wood beam 1 from the other side surface, and finally the annular reinforcing part 3 is attached to the mortise and tenon joint.
Because the protruding longitudinal wood beam 1 is shorter, the whole carbon fiber cloth 2 is adopted for reinforcement, and the waste is not too much, so the reinforcement in the mode can achieve better performance than the reinforcement of the left and right sides respectively.
As shown in fig. 3, the end of the longitudinal wooden beam 1 does not protrude from the inside of the transverse wooden beam 1, so that the mortise and tenon joint of the transverse wooden beam 1 is smooth, and the mounting of two L-shaped structures is performed under the T-shaped joint similarly to the mounting method of fig. 2.
The difference is that the bending type carbon fiber cloth 2 can not be attached above the transverse wood beam 1 any more, the way of replacing and reinforcing is to attach from the front side or the rear side of the longitudinal wood beam 1, bypass the transverse wood beam 1 connected with the top, and finally return to the longitudinal wood beam 1 from the other side, so that a side reinforcing component 4 is formed, and the concrete structure is shown in figure 3.
And finally, mounting the annular reinforcing part 3 to finish the smooth T-shaped node reinforcing mounting.
Example 3
As shown in fig. 4, this embodiment is a carbon fiber cloth reinforcement method for right angle mortise and tenon joints.
The wood beam 1 is also mortise-tenon connected horizontally and vertically, but the difference from the previous embodiment is that the connection points of the longitudinal wood beam 1 and the transverse wood beam 1 are all near the tail end of the wood beam 1, and can also be regarded as cross-shaped nodes with two shorter end points, and the concrete structure is shown in fig. 4.
The same as in example 1, pouring glue in the gaps of the mortise and tenon joints is firstly carried out, then the carbon fiber cloth 2 with an L-shaped structure is attached between two longer wood beams 1, the reinforcing mode of two shorter end points is similar to that in example 2, a longer whole piece of carbon fiber cloth 2 is adopted, the tail ends of the two shorter end points are sequentially wound from the parallel direction of the transverse wood beams 1, finally the attaching is completed until the side face of the parallel direction of the longitudinal wood beams 1, and finally the attaching of the annular reinforcing part 3 is carried out.
Similar to the smooth T-shaped joint of example 2, the right-angle joint also has a structure in which two wooden beams are embedded into each other through mortise and tenon joints and do not protrude, so that the mounting reinforcement scheme around the end points cannot be performed.
Therefore, by adopting a scheme similar to that of the smooth T-shaped joint in embodiment 2, the round mounting of the mortise and tenon joint is performed on the front and rear sides of the wooden beam, while the mounting is required to be performed on the longitudinal wooden beam 1 and the transverse wooden beam 1 respectively in the smooth right-angle joint, so as to form two side reinforcing members 4, and finally, the mounting of the annular reinforcing member 3 is performed, and the specific mounting mode is shown in fig. 5.
