Description
Technical field
The utility model relates to a kind of detection clamping device, refers in particular to two indented bars anchor poles and detects clamping device and detection system.
Background technology
Because groundwater table is higher, when the deadweight of structure and structural load descended buoyancy of water irresistibly, the anti-floating problem of underground building was also following, and needs solution badly at coastal region.In the prior art, measure of anti float commonly used is for being provided with anti-float anchor rod, and anti-float anchor rod is because it has cheap, quick, stressed advantage, its applied more and more of clearly waiting of construction.
Single indented bars anchor pole in actual engineering is owing to receive the restriction of the intensity of reinforcing bar own, the uplift resistance that can provide less (being not more than 280kN), and it is more to resist the required anchor pole quantity of unit anti-floating power; Can cause economically unreasonable, therefore, in practical engineering application; The most common with two indented bars anchor poles; Both easy to make, economical rationality is again used at most.
By the national regulation requirement, any engineering should be carried out fundamental test and detected before the formal construction of anchor pole, with the accuracy of checking design parameters and construction technology; After anchor pole has formally been constructed, should and be no less than 6 according to anchor pole sum 5% and carry out the detection of anchor pole acceptance test, whether reach designing requirement to confirm the anchor bolt construction quality, whether can carry out the construction of subsequent processing.Common anchor pole detection method generally all is a detection method of indiscriminately imitating uplift pile at present, after soon the anchor rod body reinforcing bar passes reaction beam or steel plate, is exceeding 2 bar dowels of reaction beam or steel plate part welding; Reaction beam or steel plate pass to anchor pole through these two bar dowels with uplift force; After this root anchor pole detection finishes, must reaction beam or the above reinforcing bar of steel plate be excised with cutting machine or gas cutting, just can move to next root anchor pole and detect; Every reinforced anchor bolt welding and the time of cutting need about 40 minutes approximately; An anchor pole required time is similar with detecting, and greatly reduces detection efficiency, the promptly time-consuming resource of wasting again.
The utility model content
The purpose of the utility model is to provide a kind of detection efficiency two indented bars anchor poles high, that can recycle, economize on resources and reduce cost to detect clamping device and detection system.
For reaching above-mentioned purpose, the solution of the utility model is:
A kind of two indented bars anchor poles detect clamping device, comprise anchor clamps and intermediate plate; Anchor clamps are conical, and two axial round taper holes are set on it, and the periphery in hole is provided with fan-shaped intermediate plate, and fan-shaped intermediate plate inboard is provided with the thread that is used for the clamping reinforcing bar.
Further, thread is " 7 " shape.
Further, fan-shaped intermediate plate is set to three.
Further, two axial round taper holes are symmetrical set, and two axial round taper holes are the axial symmetry setting.
A kind of two indented bars anchor pole detection systems comprise counter-force girder steel, jack, two datum line beams, two displacement transducers and are used for the anchor clamps and the intermediate plate of clamping reinforcing bar; Jack is arranged on the counter-force girder steel that places foundation pad, top, the upper end anchor clamps of jack; Two datum line beams are set in parallel in the jack both sides, and its upper end is provided with crossbeam, and crossbeam is provided with two displacement transducers that are connected with reinforcing bar respectively under the user mode; Anchor clamps are conical, and two axial round taper holes are set on it, and the periphery in hole is provided with fan-shaped intermediate plate, and fan-shaped intermediate plate inboard is provided with " 7 " the shape thread that is used for the clamping reinforcing bar.
Further, fan-shaped intermediate plate is set to three.
Further, two axial round taper holes are symmetrical set, and two axial round taper holes are the axial symmetry setting.
Further, also comprise the supportive device that is used to support the counter-force girder steel, supportive device is arranged under the counter-force girder steel, supportive device or be sleeper, or be girder steel.
Further, also comprise steel plate, steel plate is arranged between jack and the anchor clamps.
After adopting such scheme, the utility model passes an indented bars respectively with the every hole of two hole circle tapered fixtures in use, and anchor clamps are mounted to the jack upper end; In the hole, filling in intermediate plate then fixes indented bars; Pull out when detecting load when applying, uplift force is delivered on the indented bars of anchor pole through anchor clamps and intermediate plate through jack, thus the detection of realization anti-pulling capacity; After treating that this anchor pole detection finishes; Regain jack piston earlier, utilize the space between anchor clamps and the jack piston to knock chucking surface, promptly dismountable this checkout gear with weight.
Therefore, need not welding or technology such as cutting in the whole testing process, assembling and disassembling is rapid, has improved detection efficiency greatly, and it can recycle, and has practiced thrift resource, has reduced use cost.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done detailed explanation.
Consult Fig. 1 and shown in Figure 2, a kind of two indented bars anchor poles that the utility model discloses detect clamping device, comprise anchor clamps 1 and intermediate plate 2.
Two axial round taper holes 11 are symmetrical set, and two axial round taper holes 11 are the axial symmetry setting.
Fan-shaped intermediate plate 2 inboards are provided with the thread 21 that is used for the clamping reinforcing bar, and thread 21 is " 7 " shape, and " 7 " shape thread 21 is covered with fan-shaped intermediate plate 2 inboards.
Consult shown in Figure 3ly, a kind of two indented bars anchor pole detection systems that the utility model discloses comprise the anchor clamps 1 and intermediate plate 2, counter-force girder steel 3, jack 4, two datum line beams 5 and two displacement transducers 6 that are used for the clamping reinforcing bar.
Jack 4 is arranged on the counter-force girder steel 3 that places foundation pad a, and top, the upper end anchor clamps 1 of jack 4 withstand anchor clamps 1 better for making things convenient for jack 4, and supportive device 8 can be set below counter-force girder steel 3, supportive device 8 or be sleeper, or be girder steel; Simultaneously, steel plate 10 can also be set between jack and anchor clamps.
Two datum line beams 8 are set in parallel in jack 4 both sides, and its upper end is provided with crossbeam 9, and two displacement transducers 6 that are connected with reinforcing bar respectively under the user mode are set on the crossbeam 9.
