Abstract
The invention discloses a tension capacity field test device for a plastic anchor bolt. The device comprises the plastic anchor bolt, wherein the plastic anchor bolt comprises a disk and an anchor rod; the disk is arranged in a C-shaped clamp and is connected with a movable pulling rod through a switching connector at the inner side of the C-shaped clamp; the other end of the movable pulling rod is arranged on a center hole type jack; a supporting plate is arranged at an opening in the C-shaped clamp; the upper and lower parts of the supporting plate are fixed to the center hole type jack through supporting feet; a heat insulating material layer is arranged on the other side of the supporting plate; a base layer wall body is arranged outside the heat insulating material layer; the anchor rod penetrates through the supporting plate and extends into the heat insulating material layer and the base layer wall body. According to the technical scheme provided by the invention, the tension capacity field test device for the plastic anchor bolt is convenient to operate, high in efficiency and wide in application range; a detection method is reliable, and data are accurate; damage to an external heat insulating system of an outer wall, caused by detection, is reduced.
Description
Technical field
The present invention relates to the construction quality detection field, be specifically related to a kind of plastics crab-bolt tension bearing capacity site test device.
Background technology
Carry out at present plastics crab-bolt tension bearing capacity site test and there is no special-purpose equipment.Most of units are used binding strength detecting instrument to carry out plastics crab-bolt tension bearing capacity site test, this instrument manufactures and designs according to " construction work cohesive strength of decorative tile test stone " JGJ110-2008, principle is first to adopt the on-gauge plate of different size and tapestry brick to be checked to carry out secure bond, by active pull rod, on-gauge plate is connected with detector, then tests value of thrust while disconnecting of tapestry brick and basic unit and then calculate cohesive strength.The precision of this principle and instrument all can meet the requirement of plastics crab-bolt Research of Tensile Loading Capacity Test.
While with binding strength detecting instrument, detecting plastics crab-bolt tension bearing capacity, key is to solve active pull rod on the bonding strength test instrument and the connectivity problem of plastics crab-bolt, could carry out smoothly the test of tension bearing capacity.If by on-gauge plate and plastic disc surface bonding due to disc surfaces flatness and structure reasons, be difficult to effectively bond with on-gauge plate, can't complete test, even if can cement, tackifier also can be from plastic disc hole seepage flow to the base material by anchoring, and result can cause crab-bolt tension bearing capacity data bigger than normal.
The unit had has now made corresponding fixture, but need to will after plastics crab-bolt and the on-the-spot installation of this fixture, just can be tested while detecting, this method wastes time and energy, heat-insulation layer is had to damage in various degree, also do not reach the requirement of mounted plastics crab-bolt being carried out to spot sampling check, reinspection simultaneously.
Summary of the invention
The present invention is for the active pull rod solved on the bonding strength test instrument is connected with the effective of plastics crab-bolt, make easy to detect, result is effective, and a kind of plastics crab-bolt tension bearing capacity site test device is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of plastics crab-bolt tension bearing capacity site test device, comprise the plastics crab-bolt, described plastics crab-bolt comprises disk and anchor pole, described disk is arranged in the C clamp tool, described disk connects an active pull rod by the X-over of described C clamp tool inboard, the described active pull rod other end is arranged on centre-hole jack, opening part in described C clamp tool is provided with back up pad, the upper and lower of described back up pad fixes by leg and described centre-hole jack, described back up pad opposite side is provided with adiabator layer, the described adiabator layer outside is base course wall, described anchor pole through described back up pad and extend to described adiabator layer and described base course wall in.
Preferably, described leg is that two-section and inside are provided with coil tension spring.
Preferably, described active pull rod is connected by screw thread with described centre-hole jack, and bar place, described active pull rod outer end also is equipped with handle.
The invention has the beneficial effects as follows:
Adopt technical solution of the present invention, easy to operate, efficiency is high, applied range, and detection method is reliable, data are accurate, reduces the damage because of the detection External Thermal Insulation Composite Systems.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Number in the figure explanation: 1, plastics crab-bolt, 11, disk, 12, anchor pole, 2, the C clamp tool, 3, X-over, 4, active pull rod, 41, handwheel, 5, centre-hole jack, 6, back up pad, 7, leg, 8, adiabator layer, 9, base course wall.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 1, a kind of plastics crab-bolt tension bearing capacity site test device, comprise plastics crab-bolt 1, it is characterized in that, described plastics crab-bolt 1 comprises disk 11 and anchor pole 12, described disk 11 is arranged in C clamp tool 2, described disk 11 connects an active pull rod 4 by the X-over 3 of described C clamp tool 2 inboards, described active pull rod 4 other ends are arranged on centre-hole jack 5, opening part in described C clamp tool 2 is provided with back up pad 6, the upper and lower of described back up pad 6 fixes by leg 7 and described centre-hole jack 5, described back up pad 6 opposite sides are provided with adiabator layer 8, described adiabator layer 8 outsides are base course wall 9, described anchor pole 12 passes described back up pad 6 and extends in described adiabator layer 8 and described base course wall 9.
Further, described leg 7 is provided with coil tension spring for two-section and inside.
Further, described active pull rod 4 is connected by screw thread with described centre-hole jack 5, and described active pull rod 4 bar places, outer end also are equipped with handle 41
Principle of the present invention:
While detecting test, shake the handwheel 41 on active pull rod 4, uniform and stable loading load, be loaded on plastics crab-bolt 1 design load, records load value, checks the fixing situation of plastics crab-bolt 1.Utilize after active pull rod 4 without the crab-bolt fixture is installed in advance, without configuring again other fixture, because of adiabator layer 8 skin hardnesses low, may cause the sinking of detector during pull-out test, impact detects data, need to a back up pad 8 be set at C clamp tool 2 and adiabator layer 8, after site test proof adopts this device, solve effective connectivity problem of active pull rod 4 on the bonding strength test instrument and plastics crab-bolt 1.
