Description
Technical field
A kind of frame concrete punching press of the utility model impact test apparatus, belongs to building materials testing inspection field.
Background technology
A kind of concrete punching press impact test method is defined: one impacts base by the plain plate base of rigidity be firmly welded thereon four pieces of surperficial baffle plates and form in National Standard of the People's Republic of China's " cement concrete and mortar synthon " GB/T21120, four pieces of baffle plates are relative between two, and the center around steel plate base is uniformly distributed.First, level is put and is surely impacted base, again a round pie concrete sample is placed in base center, then place the hardened steel ball of a specified diameter in test specimen upper surface center, the height then making a square steel hammer specify directly over steel ball freely falls, and by steel ball, impact is acted on test specimen, repeated multiple times, contact until test specimen breaks to any three pieces in four pieces of baffle plates, record number of shocks now, in order to calculate the punching press impact property index of this test specimen.Utilize the method to test, need the test unit be suitable for, precisely control plane set-hammer height of drop, the object of handled easily to reach.
Summary of the invention
A kind of frame concrete punching press of the utility model impact test apparatus, the plane set-hammer height of drop of this device controls precisely, operates and conveniently moving.
The technical scheme that the utility model is taked is:
A kind of frame concrete punching press impact test apparatus, comprises the framed structure of base, column, crossbeam composition, four pieces of baffle plates between two relative, separated by a distance, be uniformly distributed around base center, four pieces of baffle plates are fixedly connected with base.Test specimen is placed on base, and steel ball is placed in the upper surface center of test specimen.Plane set-hammer is suspended on crossbeam by supporting rod by clamper.
Two root posts, in the mode be threaded, are vertically fixed on the both sides of base symmetrically.
Crossbeam is a strip band steel plate, two ends perforate, and crossbeam is connected with the upper end of column, and the junction of crossbeam and column is provided with setting nut.
The middle part perforate of crossbeam, clamper is fixed on crossbeam by the mode connected by screw rod.
Clamper is a manually fastened drill bit folder, and when being fixed on crossbeam, Open Side Down.
Plane set-hammer is a cube bloom, and one center side place has screw, is threaded connection supporting rod.
Steel ball is hardened steel ball.
Described base is a rectangle steel plate.
Supporting rod is that threaded short thin rod iron is established in one end, and its diameter is in the suitable clamping range of clamper.
A kind of frame concrete punching press of the utility model impact test apparatus, the framed structure that the steel plate base of this test unit, column, crossbeam form, fixedly support is provided for plane set-hammer, the distance that falls of accurate calibration plane set-hammer is convenient in the setting of setting nut, clamper is manually fastened drill bit folder, can freely fix and discharge plane set-hammer, easy to operate.In device except steel ball, other each several part can be combined, and forms an entirety, is convenient to mobile.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model test unit.
Embodiment
As shown in Figure 1, a kind of frame concrete punching press impact test apparatus, is made up of base 1, baffle plate 2, column 3, crossbeam 4, clamper 5, supporting rod 6, plane set-hammer 7, steel ball 8 and setting nut 10.
Base 1 is a rectangle steel plate, and between two relatively and the distance of regulation of being separated by, the upper surface center around steel plate base is uniformly distributed, and is welded on securely in steel plate base for four pieces of baffle plates 2.Two root posts 3 are vertically fixed on the both sides of steel plate base symmetrically in the mode be threaded.Crossbeam 4 is a strip band steel plate, and two ends perforate, is connected with the upper end of column 3, and by setting nut 10 adjusting position with fixing.The middle part perforate of crossbeam 4, is fixed on clamper 5 on crossbeam 4 in order to the mode connected with screw rod.Clamper 5 is manually fastened drill bit folders, and when being fixed on crossbeam 4, Open Side Down.Plane set-hammer 7 is cube blooms, and one center side place has screw, is firmly connected to supporting rod 6 by screw thread.Supporting rod 6 is for establishing threaded short thin rod iron in one end, and its diameter is in the suitable clamping range of clamper 5.Plane set-hammer 7, by supporting rod 6, can be suspended on crossbeam 4 by clamper 5.Steel ball 8 is the hardened steel ball of a specified diameter.
During use, first each several part of test unit is fitted together, be steadily positioned on solid supporting surface, such as ground.Then, the setting nut 10 of adjustment both sides, makes falling apart from the regulation meeting specification of plane set-hammer 7.Then, test specimen 9 is lain against the upper surface center position of steel plate base, then steel ball 8 is placed in the upper surface center position of test specimen 9, unclamp clamper 5, plane set-hammer 7 falls, and impacts steel ball 8, realizes impacting the punching press of test specimen 9.Observe test specimen 9 whether to contact, if do not had with any three pieces in four pieces of baffle plates 2; Then plane set-hammer 7 is clamped on clamper 5 by supporting rod 6 again, continues punching press impact test piece 9, until test specimen 9 breaks to the degree of regulation, write down number of shocks, termination test.
