Description
Technical field
The utility model relates to Test Technology of Pile Foundation field, and especially a kind of foundation pile vertically pulling-resistant detects connector.
Background technology
It is a kind of method of the stake in engineering being carried out to testing inspection that unit for single-pile vertical anti-pulling static loading test detects, to determine vertical ultimate uplift resistance of single pile; Judge whether vertically pulling-resistant bearing capacity meets design requirement; By Internal forces and deformation test, measure the resistance to plucking frictional resistance of stake.
Traditional detection method is after welding the main muscle of spreading pile cages, symmetry is wrapped on reaction beam, when can not ensure that the main muscle of stake stretches, out of plumb causes pulling force uneven, welding operation is not strong, when being overlapped on reaction beam, reinforcing bar and reaction beam edge are point cantact, when stressed for easily to be cut, there is potential safety hazard, reason is as follows: (1) by bar splicing at reaction beam, lap segment contacts with reaction beam with certain radian shape, namely sentencing point contact mode in reaction beam two edges, there is drawback in this way of contact, and this point easily produces cutting in tension process.(2) the main muscle of reinforcing cage is overlapped on after on reaction beam, and in inverted-triangular tension, stake top reinforcing cage intermediate concrete pressurized, the not free vertical tension of main muscle, discontinuity, does not represent the true uplift resistance of stake.
Utility model content
The utility model is for the deficiencies in the prior art, and propose a kind of foundation pile vertically pulling-resistant and detect connector, structure is ingenious, easy to use.
In order to realize above-mentioned utility model object, the utility model provides following technical scheme: a kind of foundation pile vertically pulling-resistant detects connector, comprise reaction beam, jack, supporting plate, pull bar and cylinder, described reaction beam is erected at directly over foundation pile, described jack is positioned on the described reaction beam directly over described foundation pile, described supporting plate is located on described jack, and described cylinder is fixedly connected with the main muscle cage of described foundation pile, and described pull bar two ends are fixedly connected with described cylinder with described supporting plate respectively.
Further, on the axis being centrally located at described foundation pile of described reaction beam.
Further, described pull bar is provided with even number, is connected to equably on described cylinder.
Further, the external diameter of described cylinder and the equal diameters of the main muscle cage of described foundation pile.
Further, the main muscle cage of described cylinder and described foundation pile is for being welded and fixed.
Further, described pull bar two ends are each passed through described supporting plate and described cylinder, are fixedly connected with corresponding nut.
Compared with prior art, the utility model has the following advantages: on reaction beam, arrange jack and supporting plate, then combines the cylinder be connected with the main muscle cage of foundation pile, and the face contact of employing substitutes traditional point cantact, increases by force intensity; The connection of cylinder and main muscle cage is even, such that the main muscle of every root is parallel, uniform stressed state, makes safety in resistance to plucking process, reliable, strong operability.
Accompanying drawing explanation
Fig. 1 is that the utility model foundation pile vertically pulling-resistant detects the structural representation of connector and installs and uses schematic diagram.
Detailed description of the invention
Be described in detail the utility model below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
A kind of foundation pile vertically pulling-resistant as shown in Figure 1 detects connector, comprise reaction beam 2, jack 3, supporting plate 4, pull bar 5 and cylinder 6, described reaction beam 2 is erected at directly over foundation pile 8, described jack 3 is positioned on the described reaction beam 2 directly over described foundation pile 8, described supporting plate 4 is located on described jack 3, described cylinder 6 is fixedly connected with the main muscle cage 7 of described foundation pile 8, and described pull bar 5 two ends are fixedly connected with described cylinder 6 with described supporting plate 4 respectively.
Carry out leveling compacting to all grounds of detected engineering pile stake, setting up reaction beam 2 by directly over inspection foundation pile 8, lift jack 3 in the middle of reaction beam 2, jack 3 is placed in directly over foundation pile 8 center, and jack 3 provides power.The supporting plate 4 made in advance is covered, each remaining 4 tie rod holes of supporting plate 4 front two rows above jack 3.Then in hole, put on front and back 2 arrange totally eight pull bars 5, upper end is connected with supporting plate 4 nut, the suspention of pull bar 5 lower end connects cylinder 6, connecting cylinder 6 surrounding sidewall weld foundation pile 8 extends on main muscle cage 7, connect herein and need firm welding, in case testing inspection process generation security incident, finally screw square bolt on supporting plate 4, keep pull bar 5 little tension.
The each main muscle stretched out by foundation pile reinforcing cage 7 adjusts, and makes it ensure nature straight configuration, is close to by main muscle outside cylinder 6 and ensures to increase contact area, carry out the welding compared with long overlap length.
Cylinder 6 top is stretched out two row's pull bars 5 directly to carry out nut with supporting plate 4 and be connected, pull bar 5 equalization is symmetrically distributed in reaction beam 2 both sides.Supporting plate 4 drops on jack 3, and jack 3 drops on reaction beam 2, and reaction beam 2 is erected at above foundation pile 8 through buttress 1.
By the mounting means shown in Fig. 1, foundation pile 8 arranges displacement meter 11, and datum line beam 9, magnetic stand 10 are aside set, can complete and the vertically pulling-resistant power of foundation pile 8 is detected.
Foundation pile vertically pulling-resistant detects connector, and bottom is arranged and foundation pile 8 reinforcing cage 7 equal diameter or smaller cylinder 6, and the main muscle of reinforcing cage 7 overlaps with cylinder 6 sidewall and welds, and ensures that main muscle evenly vertically freely stretches.Cylinder 6 upper end closed arranges two row's tie rod holes, and pull bar 5 carries out nut with top supporting plate 4 and is connected, and supporting plate 4 directly connects with the jack 3 on reaction beam 2, and structure is simple, with low cost, simple to operate, easy to use, operating efficiency is high, and can reuse, and does not restrict in addition by space factor.
The utility model improves uplift resistance hereditary property and there occurs change, instead of traditional point contact with the contact of face formula, to cause in loading procedure uniform force, safe and reliable.
The utility model carries out simple nuts connection, changes uplift resistance and transmits form, safe and reliable.In addition, carry out simple bolt and nut and connect and the main muscle welding of cylinder, and fast connect, strong operability.
