In " small on-farm water infrastructures is filled with row's canal precast concrete and made and detection technique code ", the reaction frame of the instrument for testing compressive strength of U-type groove is assembled, and each use all needs assembling, dismounting detector, is unfavorable for improving detection efficiency; And the factor such as lifting jack and member dead weight need be considered during the calculating of external pressure strength result, add the error of result of calculation; In use, due to its volume and deadweight comparatively large, be unfavorable for carrying, in addition, girder, component reinforcing bar and the U-type groove of holding up are when compression damage falls from eminence, and probably cause the injury to personnel participating in detecting, its detect security is had a greatly reduced quality.Therefore, need develop and can improve detection efficiency, accuracy, and ensure the Novel U-shaped groove detection apparatus detecting safety.
Team of the present invention also once have developed the instrument for testing compressive strength reaction frame (patent No. CN201420432758.8, Horizontal U-shaped groove instrument for testing compressive strength reaction frame) of other kinds, but only may be used for outer pressure resistance detection.Therefore, need to develop the unified U-type groove pick-up unit detected of inside and outside Compressive Strength.
Summary of the invention
The object of the present invention is to provide a kind of device that can realize the inside and outside Compressive Strength of U-type groove and detect, the inside and outside Compressive Strength of U-type groove can be realized and detect.
The present invention is achieved like this: the inside and outside Compressive Strength pick-up unit of U-type groove, comprise the reaction frame framework of the rectangle that the reaction frame cruciform bracing parallel with two by the reaction frame Frame Side Beam that two, left and right is parallel is formed, two parallel reaction frame cruciform bracings arrange lifting jack brace summer, bearing beam, the two is parallel and in same level, bearing beam at left, lifting jack brace summer on the right side; Described lifting jack brace summer, bearing beam, all can be free to slide on reaction frame cruciform bracing, reaction frame framework corner setting height(from bottom) regulates heel brace.
Preferably, described height regulates heel brace to be made up of height adjustment bolt sleeve and height adjustment bolt, and height adjustment bolt sleeve is arranged in height adjustment bolt, and height adjustment bolt sleeve and reaction frame framework corner link together.
Preferably, the two ends of lifting jack brace summer, bearing beam are all fixedly connected with sliding bearing, and each sliding bearing is set on reaction frame cruciform bracing.
Preferably, the material of reaction frame Frame Side Beam is square steel, and the material of reaction frame cruciform bracing is round steel.The material of lifting jack brace summer, bearing beam is square steel.
Preferably, for ensureing the strength and stiffness of lifting jack brace summer, using two and being formed by connecting with the square steel of the same specification of bearing beam, for ensureing that it does not produce excessive deformation and friction in use, special outfit two groups totally 4 slide blocks.
Reaction frame framework of the present invention can by being arranged on height adjustment bolt on reaction frame framework corner and height adjustment bolt sleeve regulates height.Lifting jack brace summer, bearing beam can move freely at reaction frame cruciform bracing, therefore by regulating the position of lifting jack brace summer, bearing beam, and at lifting jack brace summer, U-type groove instrument for testing compressive strength (i.e. jack system) is installed, thus achieve the comprehensive of U-type groove inside and outside Compressive Strength detector, improve detection efficiency.

Embodiment
As shown in Figure 4, the inside and outside Compressive Strength pick-up unit of a kind of U-type groove, comprise the reaction frame framework of the rectangle that the reaction frame cruciform bracing 301 parallel with two by the reaction frame Frame Side Beam 308 that two, left and right is parallel is formed, two parallel reaction frame cruciform bracings 301 arrange lifting jack brace summer 304, bearing beam 303, the two is parallel and in same level, bearing beam 303 at left, lifting jack brace summer 304 on the right side; Described lifting jack brace summer 304, bearing beam 303 all can be free to slide on reaction frame cruciform bracing 301, and reaction frame framework corner rational height adjusting bolt sleeve 306, height adjustment bolt sleeve 306 is arranged in height adjustment bolt 302.
The two ends of lifting jack brace summer 304, bearing beam 303 are all fixedly connected with sliding bearing 307, and each sliding bearing 307 is set on reaction frame cruciform bracing 301.
The material of reaction frame Frame Side Beam 308 is square steel, and the material of reaction frame cruciform bracing 301 is round steel.
The material of lifting jack brace summer 304 and bearing beam 303 is square steel.
For ensureing the strength and stiffness of lifting jack brace summer, lifting jack brace summer uses two to be formed by connecting with the square steel of the same specification of bearing beam, for ensureing that it does not produce excessive deformation and friction in use, and special outfit two groups totally 4 slide blocks.
Configuration level adjusting bolt 309 on reaction frame Frame Side Beam 308, horizontal adjustment bolt 309 has two effects, one is that can to fix lifting jack brace summer 304, two be when when U-type groove A/F is less, U-type groove instrument for testing compressive strength 305 stroke is inadequate, can Compensation Regulation horizontal level.
As shown in Figure 5, do internal pressure test when using, first regulate its whole height with the height adjustment bolt 302 of corner and height adjustment bolt sleeve 306.U-type groove is positioned over inside reaction frame framework, but lifting jack brace summer 304, bearing beam 303 are positioned over U-type groove opening inner side, and lifting jack brace summer 304 installs hydraulic jack.U-type groove instrument for testing compressive strength pressurizes, and test, now power is conducted to bearing beam 303, lifting jack brace summer 304 by hydraulic jack, thus U-type groove is strutted destruction from inside, and after off-test, hydraulic jack is by automatic retracted.
As shown in Figure 6, do external pressure test when using, first regulate its whole height with the height adjustment bolt 302 of corner and height adjustment bolt sleeve 306.U-type groove be positioned over inside reaction frame framework, lifting jack brace summer 304, bearing beam 303 are all positioned on the right side of U-type groove.Lifting jack brace summer 304 installs hydraulic jack.Pressurization, tests, and now power is conducted to reaction frame Frame Side Beam 308, the bearing beam 303 in left side by hydraulic jack 305, thus U-type groove is destroyed from external compression, and after off-test, hydraulic jack is by automatic retracted.
