The tensile frock of this kind of anchor board simple structure is adapted to and carries out tensile test to various anchor board test pieces, and can guarantee that the atress acts on along anchor board test piece axis, but bulky, weight are heavy, very inconvenient use. After the lower jaw is used for multiple times, the lower end of the lower pull rod 15 is repeatedly clamped by the lower jaw, the appearance is seriously damaged, and the clamping effect is influenced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art not enough, provide a tensile frock of anchor board small, light in weight and facilitate the use.
In order to solve the technical problem, the utility model discloses the technical scheme who takes is:
an anchoring plate stretching tool comprises a stretching rod, a stretching tool shell and a stretching base plate movably arranged in the stretching tool shell; a center hole is formed in the center of the top end of the stretching tool shell, and a center hole is also formed in the center of the stretching base plate; the bottom of tensile frock casing opens the setting, the top of tensile pole is provided with the inflation head to the inflation head passes through threaded connection in the bottom mouth of tensile frock casing.
Furthermore, double threads are formed in the inner wall of the open end of the stretching tool shell, and double threads are formed in the outer peripheral surface of the expansion head.
Furthermore, the bottom end of the stretching rod is connected with an outer sleeve through threads.
Further, a handle is arranged on the outer wall of the stretching tool shell.
Adopt the produced beneficial effect of above-mentioned technical scheme to lie in:

Compare with current tensile frock, the utility model discloses greatly reduced frock weight, small, convenient to use have improved test efficiency.
The utility model discloses there is the outer tube at the position of the bottom of tensile pole by keeping silent the centre gripping down, can protect tensile pole effectively and avoid the centre gripping injury of keeping silent down, can be convenient change after the outer tube damages, and need not change tensile pole, just so prolonged the life of tensile pole greatly, reduced experimental expense.
Drawings
FIG. 1 is a schematic structural diagram of a conventional anchor plate stretching tool;
FIG. 2 is a schematic structural view of the anchor plate stretching tool of the present invention;
in the figure: 11. the device comprises an upper bottom plate, 12, a lower bottom plate, 13, a sleeve, 14, bolts, 15, lower pull rods, 16 and an anchoring plate test piece; 21. the device comprises a stretching rod 22, an outer sleeve 23, a stretching tool shell 24 and a stretching base plate.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2, the utility model discloses an anchor plate stretching tool, which comprises a stretching rod 21, a stretching tool shell 23 and a stretching base plate 24 movably arranged in the stretching tool shell 23; a center hole is formed in the center of the top end of the stretching tool shell 23, and a center hole is also formed in the center of the stretching base plate 24; the bottom end of the stretching tool shell 23 is opened and arranged, the top end of the stretching rod 21 is provided with an expansion head, and the expansion head is connected into the bottom end opening of the stretching tool shell 23 through threads.
The utility model discloses a tensile backing plate 24 can be changed according to stock (reinforcing bar) specification to realize the tensile test of different specification anchor boards.
Double threads are formed in the inner wall of the open end of the stretching tool shell 23, and double threads are formed in the outer peripheral surface of the expansion head. Threaded connection between the bottom end of the stretching tool shell 23 and the expansion head of the stretching rod 21 adopts a double-thread structure, so that an operator can conveniently rotate and close the stretching tool shell 23 and the stretching rod 21, and the test efficiency is improved.
