Description
Technical field
Straight cutting dish pin formula falsework node pull-out bond test member, belongs to building template support experimental facilities field, is specifically related to a kind of falsework forces testing device.
Background technology
Promotion and application along with building operation straight cutting dish pin formula falsework, its popularity is more and more extensive, feature due to its support system, its security is subject to increasing attention, node withdrawal resistance is an important indicator of its security of reflection, therefore, node pull-out bond test is very important, and traditional straight cutting dish pin formula falsework node pull-out bond test member processing method is various, but all more random, processing is inconvenient, operate not strict, there is a big difference for the withdrawal resistance size that makes to record and True Data, the security performance that can not effectively reflect support.For this reason, need to design a kind of more convenient operation, be easy to use, measured value can more accurately reflect the test component of support node withdrawal resistance size.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to operate, measured value is accurate, can more effectively reflect the test component of straight cutting dish pin formula falsework node withdrawal resistance size.
The utility model solves the technical scheme that its technical matters adopts: this straight cutting dish pin formula falsework node pull-out bond test member, it is characterized in that: comprise vertical rod and the cross bar that can be plugged in together, top, described vertical rod outer ring is socketed with terminal pad, on terminal pad, have a plurality of dishes hole, the uniform a plurality of lower attaching nuts in bottom, vertical rod outer ring, dish hole is identical with lower attaching nut's quantity and coaxial corresponding up and down; Described cross bar termination is connected with straight inserting head, and insertion dish in straight inserting head bottom in hole links together vertical rod and cross bar, and straight inserting head top is provided with a upper attaching nut, upper attaching nut and the lower attaching nut corresponding with it be connected with respectively vertically towards connecting rod.Fixture on instrument clamps respectively upper and lower connecting rod by experiment, and experimental apparatus applies respectively pulling force to upper and lower two connecting rods, thereby test straight inserting head departs from the power size in the dish hole of terminal pad, draws support node withdrawal resistance size.
Described vertical rod and cross bar all adopt steel pipe cutting to be made.
Described terminal pad adopts steel plate more than thickness 10mm to be made, and terminal pad center has the center circle adapting with vertical rod external diameter, and center circle periphery evenly has the dish hole of a plurality of rectangles.Terminal pad is socketed in vertical rod outer ring firm welding.
A side of described straight inserting head bottom is for being with angled dip plane.Straight inserting head bottom can be stretched in rectangular disk hole.
The threaded rod that described connecting rod adapts for the internal thread with lower attaching nut and upper attaching nut, the connecting rod on top stretches out upward, and the connecting rod of bottom stretches out down.The link end by experiment fixture of instrument is fixed.
Compared with prior art, the beneficial effect that the utility model has is:
This straight cutting dish pin formula falsework node pull-out bond test element structure is simple, main vertical rod and the cross bar mechanism being plugged in together that arrange, and can scientific and effectively reflect node withdrawal resistance size by the experimental facilities that pulling capacity is tested in cooperation, easy to operate, test figure by experiment equipment accurately reflects, avoided rough formula test method in the past, be conducive to test specification, and made data reflect more accurately straight cutting dish pin formula falsework node withdrawal resistance size.
Accompanying drawing explanation
Fig. 1 is the front view of this straight cutting dish pin formula falsework node pull-out bond test member.
Fig. 2 is the vertical view of this straight cutting dish pin formula falsework node pull-out bond test member.
Wherein: 1, vertical rod 2, terminal pad 3, straight inserting head 4, cross bar 5, lower attaching nut 6, connecting rod 7, upper attaching nut.
Embodiment
Fig. 1 ~ 2nd, most preferred embodiment of the present utility model, is described further below in conjunction with 1 ~ 2 pair of the utility model of accompanying drawing.
With reference to accompanying drawing 1,2: straight cutting dish pin formula falsework node pull-out bond test member, comprise vertical rod 1 and the cross bar 4 that can be plugged in together, vertical rod 1 and cross bar 4 all adopt steel pipe cutting to be made, and vertical rod 1 specification is Φ 48.3mm * 3.6mm, and cross bar 4 specifications are Φ 48.3mm * 3.0mm.
Principle of work is as follows: during test, with being not less than the hand hammer that 0.5kg is heavy, beat straight inserting head 3 tops, straight inserting head 3 bottoms are closely inserted in the dish hole of terminal pad 2, for avoiding occurring eccentric force when the pull-out test, upper attaching nut 7 on straight inserting head 3 and the lower attaching nut 5 of below correspondence are on same axis, the connecting rod of upper and lower 6 is screwed into respectively in the lower attaching nut 5 of upper attaching nut 7 and below correspondence, with be fixedly clamped the respectively connecting rod 6 of upper and lower of the fixture on experimental apparatus, and carry out pull-out test, the size of the power in the dish hole of test straight inserting head 3 disengaging terminal pads 2, draw falsework node withdrawal resistance size, the numerical value recording is accurate.
