Abstract
The utility model provides a foundation anchor pile stretching resistance experimental device. The utility model is characterized in that two jacks which are symmetrically placed are arranged between an upper flat plate and a lower padding plate, and an upper connecting head is arranged on the upper flat plate. The upper and the lower two ends of an electronic force measuring transducer are respectively connected with the upper connecting head and a lower connecting head, and the lower connecting head is connected with the reinforcing steel bar of a hole pile when the utility model is used. Simultaneously the two jacks are started, and the binding strength of the reinforcing steel bar and a concrete pile can be displayed through the electronic force measuring transducer. The utility model has the advantages of simple structure, small size, convenient carrying, flexible use, good adaptability, etc., and the utility model is suitable for being used in a building site.
Description
The utility model belongs to tensile test apparatus, particularly a kind of simple and easy tensile test device of basic anchor pole that is used for the building ground.
On the building ground, in order to examine the bond strength of reinforcing bar and concrete and reinforced concrete and ground rock, after giving the fixed pouring time limit, to carry out tensile test to reinforcing bar or to whole hole stake of squeezing into rock sometimes, especially hydraulic engineering, this test is then had no choice but to.Yet the instrument that carries out this test is similar to existing universal testing machine, and volume is big, heavy, and has only R﹠D institution just to possess.Whenever do single test, move, install all and must spend many periods, the testing expenses costliness is difficult to carry out many units in charge of construction, carries out this test for the more first method of the construction of outlying mountain area.
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, carries and use the simple and easy tensile test device of all basic very easily anchor pole.
Above-mentioned task is achieved in that this test unit, by upper flat plate, lower bolster, lifting jack, electronics force cell, top connection with lower sub is formed, be combined into such structure when using; Place two lifting jack having on the lower bolster of central through hole symmetry, place upper flat plate in the above, top connection is connected the connection lower sub of electronics force cell bottom with the center pit that the screw rod of its underpart passes upper flat plate with the electronics force cell.
Below in conjunction with accompanying drawing assembling of the present utility model and operating position are described further:
Fig. 1 is the synoptic diagram of a kind of concrete structure of the utility model and user mode.
The utility model is like this work as shown in Figure 1: now lower bolster (8) is placed on the base surface, allow its central through hole (9) align piles hole, lower contact (6) is attached on the tested reinforcing bar (10) by welding or other mode of connection, nut (5) with electronics force cell (4) is screwed in the lower contact (6) then, the person of connecing is at upper symmetrical anti-two jack (7) of lower bolster (8), again upper flat plate (2) is placed on the jack (7), the screw rod of top connection (1) is passed upper flat plate (2) centre bore and electronics force cell (4) nut (3) links, and starts simultaneously at last two jack (7), and reinforcing bar (10) is carried out tension test, and its tensile strength just shows by electronics force cell (4). Through overtesting, the power value error of the utility model test can guarantee to have met instructions for use fully within≤1%.
Store behind the utility model Detachable, just assemble when transportation is used, compared with the prior art, have simple in structure, volume is little, easy to carry, use flexibly and the good advantage of adaptability.
When implementing, can be anchored on the upper flat plate (2) for the ease of top connection (1), a clamp nut (11) also is set on the screw rod of top connection (1).
Claims (2)
1, the simple and easy tensile test device of a kind of basic anchor pole, it is characterized in that it being by upper flat plate (2), lower bolster (8), lifting jack (7), electronics force cell (4), top connection (1) and lower sub (6) are formed, be assembled into following structure during use: two lifting jack (7) are symmetrically placed on the lower bolster (8), place upper flat plate (2) in the above, center pit and electronics force cell (4) binding that top connection (1) is passed upper flat plate (2) with the screw rod of its underpart, the bottom of electronics force cell (4) is connected with lower sub (5).
2, tensile test device according to claim 1 is characterized in that also being provided with a clamp nut (11) on the screw rod of top connection (1).
