The utility model comprises upper and lower two loading heads, and fixedly connected a plate below last loading head, the center line of this web joint and last loading head are positioned on the same vertical axis, and detachable bolt group is set on web joint; The upper fixed of following loading head connects a base, arranges detachable bolt group on base.
In the time need testing to the nail specimen joints that the OSB plate is connected with dimension stock band direction, vertically be connected web joint on by detachable bolt group dimension stock, the OSB oriented wood chipboard also laterally is connected on the base by corresponding detachable bolt group, will goes up the upper grip and the lower chuck of loading head, following loading head and drawing machine respectively and fix.By drawing machine work, just can test out the relevant parameter value of this nail specimen joints.
In the time need testing to the nail specimen joints that the OSB plate is connected with dimension stock rift grain direction, vertically be connected web joint on by detachable bolt group dimension stock, the OSB plate also vertically is connected on the base by corresponding detachable bolt group, will goes up the upper grip and the lower chuck of loading head, following loading head and drawing machine respectively and fix.By drawing machine work, just can test out the relevant parameter value of this nail specimen joints.
The utility model is simple and reasonable for structure, the convenient making, and convenient the use by this simple and easy to do auxiliary clamp, need not be transformed especially, just can test out nail node component parameter by general drawing machine.
In order to strengthen connective stability to tested object, arrange four detachable bolt groups on the web joint, be divided into two rows and arrange that two detachable bolt groups of every row are arranged symmetrically in the center line both sides of web joint.
For making things convenient for the clamping test object, between web joint and detachable bolt group, be provided with top board.
In like manner,, also arrange four detachable bolt groups on the utility model base, be divided into two rows and arrange that two detachable bolt groups of every row are arranged symmetrically in the center line both sides of web joint in order to strengthen connective stability to tested object.
Simultaneously, between base and detachable bolt group, be provided with lower platen.
For convenience, on the last loading head horizontal connecting hole can be set with being connected of drawing machine.During test, in connecting hole, place coupling bolt, can be connected with the drawing machine chuck easily by coupling bolt.
In like manner, also horizontal connecting hole can be set on the following loading head.
