The bottoms of the four round bars are connected with a lower slide head. The lower joint comprises a base plate, four round bars connected with the base plate and an upper slide head connected with the round bars. The upper slide head and the lower slide head are both provided with openings which enable round bars at the same side to slide. A test piece is arranged between the upper slide head and the lower slide head. The invention can provide a simple device for testing tensile strength. Meanwhile, by the utilization of the device and by means of a general servo press, a tensile stress-strain full curve of building materials such as concrete and the like can be measured, and the effect is remarkable. The multipurpose compressive tensile reaction frame has good business value and experiment effect.

Based on this, provide a kind of counterforce device of delicate structure, realize general pressing machine convert pressure to pulling force by arranging reaction frame, just seem particularly important.
Summary of the invention
For solving above-mentioned prior art Problems existing, a kind of multipurpose press is the object of the present invention is to provide to draw reaction frame.The present invention can convert pressure to pulling force, and due to larger pulling force will be provided more difficult, but provide larger pressure to be easy to realize, a lot of instrument all can only provide pressure not provide pulling force at present, and most of pressing machine can only the compressive strength of test block and compressive stress-strain full curve, and cannot tested for tensile strength and tension stress-strain full curve, but tensile strength is also an important indicator in our concrete building material, especially tension stress-strain full curve is at component, be absolutely necessary during the analysis of structural finite element analysis scheduling theory condition, patent of the present invention can provide a kind of simple mechanism of tested for tensile strength, we can utilize this device and measure the tension stress-strain full curve of the building materialss such as concrete by general servo-pressing machine simultaneously, this is maximum beneficial effect.
For achieving the above object, technical scheme of the present invention is:
A kind of multipurpose press draws reaction frame: comprise top connection and lower sub, described top connection comprises top board and is connected four round bars with top board, lower slider head is connected bottom four round bars, four round bars that described lower sub comprises base plate and is connected with base plate, and the upper slide head to be connected with round bar, described upper slide head and lower slider head are provided with the perforate of sliding for homonymy round bar, between described upper slide head and lower slider head, are provided with test specimen.
Further, described upper slide head and the center perforate of lower slider head, be connected with the bolt for fixing test specimen, be provided with pad between bolt and upper slide head and lower slider head.
Further, described top board area is less than base plate.
Further, described bolt is connected with backing plate, compresses test specimen by the backing plate of test specimen both sides.
Relative to prior art, beneficial effect of the present invention is:
The present invention can convert pressure to pulling force, and due to larger pulling force will be provided more difficult, but provide larger pressure to be easy to realize, a lot of instrument all can only provide pressure not provide pulling force at present, and most of pressing machine can only the compressive strength of test block and compressive stress-strain full curve, and cannot tested for tensile strength and tension stress-strain full curve, but tensile strength is also an important indicator in our concrete building material, especially tension stress-strain full curve is at component, be absolutely necessary during the analysis of structural finite element analysis scheduling theory condition, patent of the present invention can provide a kind of simple mechanism of tested for tensile strength, we can utilize this device and measure the tension stress-strain full curve of the building materialss such as concrete by general servo-pressing machine simultaneously, Be very effective, there is good commercial value and experiment effect.

Embodiment
Below in conjunction with the drawings and the specific embodiments, technical solution of the present invention is described in further detail:
As Figure 1-5: a kind of multipurpose press draws reaction frame: comprise top connection 1 and lower sub 2, described top connection 1 comprises top board 3 and is connected four round bars 4 with top board 3, lower slider 5 is connected bottom four round bars 4, four round bars 4 that described lower sub 2 comprises base plate 6 and is connected with base plate 6, the upper slide head 7 that round bar 4 other end connects, described upper slide head 7 and lower slider 5 is provided with the perforate of sliding for homonymy round bar 4, between described upper slide head 7 and lower slider 5, is provided with test specimen 8.
Further, the 5 center perforate of described upper slide head 7 and lower slider, are connected with the bolt 8 for fixing test specimen, are provided with pad 10 between the connected upper slide head 7 of bolt 8 and lower slider 5.
Further, described top board 3 area is less than base plate 6.
Further, described bolt 9 is connected with backing plate 11, compresses test specimen 8 by the backing plate 11 of test specimen 8 both sides.
1-top connection, 2-lower sub, 3-top board, 4-round bar, 5-lower slider head, 6-base plate, the upper slide head of 7-, 8-test specimen, 9-bolt, 10-pad, 11-backing plate.
Principle of work of the present invention is: the present invention makes pressure replace actual pulling force by arranging reaction frame.Reaction frame principle of work: whole reaction frame is divided into two can the top connection 1 of mutual socket of self-movement and lower sub 2, is connected test specimen 8 by the bolt 9 in upper slide head 5 and the lower slider 7 at middle part or is connected test specimen 8 through backing plate 11.By giving top board 3 and base plate 6 pressure, through round bar 4 and the upper slide head 7 connected thereof and lower slider 5, pressure is converted to pulling force, thus realize pressure and draw conversion, make two of reaction frame the entirety of self-movement can produce motion mutually, pulling force is produced in the upper and lower surface of test specimen, and make ordinary press by original only to produce pressure, produce pulling force by the effect of reaction frame.While loading, computer system can gather the distortion of test specimen.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
