Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Example (b):

a novel prestressed carbon fiber plate comprises a carbon fiber single plate 1 and a clamping and fixing strip 2, wherein a clamping groove 11 penetrating the length of the carbon fiber single plate 1 is formed in the side wall of the carbon fiber single plate 1, the clamping and fixing strip 2 is provided with a clamping strip 21 which is clamped in the clamping groove 11 in a matched mode, the clamping and fixing strip 2 is of a gourd shape, and the cross section of the clamping strip 21 is of a large semicircular shape; when two carbon fiber veneer 1 splice into a whole when needs, place joint fixed strip 2 between two plate bodys to install joint strip 21 cooperation in joint groove 11, thereby connect into a whole with two carbon fiber veneer 1, such concatenation mode is simple relatively convenient, and when depositing the transportation, mosaic structure also does not influence at all.

As shown in fig. 1, the side wall of the carbon fiber single plate 1 is provided with a groove 12 penetrating the length thereof, and the clamping groove 11 is arranged in the groove 12.

As shown in fig. 1 and 3, the length of the clamping strip 21 is smaller than that of the clamping groove 11; the fixing block 13 is further included, and a clamping block 131 which is matched and clamped at the end portion of the groove 12 is arranged on the fixing block 13.
