Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operating principle etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
As Fig. 1 is depicted as this foundation pile for building, comprise bar steel plate 1 and pile 2, the both ends that pile 2 is fixed on bar steel plate 1 form a foundation pile unit, and foundation pile unit has one at least; Multiple foundation pile unit combination can use according to actual conditions by above-mentioned foundation pile unit, the center correspondence of the bar steel plate 1 on single foundation pile unit is fixed together during combination, composition foundation pile combination as shown in Figure 1.During use, this foundation pile is inserted in the pedestal installing hole excavated on stone surface, mountain, can thereon by normal procedure building constructions thing after foundation pile installs.
As shown in Fig. 2, the main body of pile 2 is in the pedestal installing hole that inserts foundation surface and excavate, this foundation pile seat is that whole building provides support by the stable reinforcement stabilising arrangement arranged on each pile 2, this reinforcement stabilising arrangement can trigger under the Action of Gravity Field of building main body, the stability of single stanchion can be strengthened, thus strengthen the stability of whole pedestal, guarantee that whole pedestal has enough support forces, whole foundation pile is modularized design in addition, so whole foundation pile is installed, convenient disassembly.
As shown in Fig. 3 ~ 7, this pile 2 comprises epimere 21 and hypomere 22, hypomere 22 is inserted in epimere 21, be inserted in the many motion bars 3 in hypomere 22, be located in the epimere 21 of pile 2 for driving the motion bar 3 laterally outwardly actuator 51 that stretches out of side, and the back-moving spring 32 for resetting, actuator 51 is provided with the conical drive surface contacted with motion bar 3.The inside of pile 2 epimere 21 is fixedly installed the mounting blocks 5 for installing actuator 51 at bottom position place.As shown in Fig. 7, actuator 51 is cone, and the drive surface of actuator 51 is taper seat, actuator 51 is arranged on the bottom surface of mounting blocks 5, mounting blocks 5 is cylindrical, and mounting blocks 5 is bolted on the epimere 3 of pile 2, and the outer circumference surface of mounting blocks 5 is provided with screwed hole.
As shown in Figure 7, actuator 51 and mounting blocks 5 are formed in one, and form an entirety.As shown in Fig. 5,6, the back-up block 4 for installing motion bar 3 is fixedly installed in the inside of pile 2 hypomere 22, four motion bars 3 are installed in back-up block 4, motion bar 3 is uniformly distributed along the circumferential of back-up block 4, in order to fixing more firm, the stability of further enhancing foundation pile, suitably can increase the number of motion bar 3.
As shown in Figure 4, back-up block 4 is cylindrical, back-up block 4 is provided with the pilot hole 42 for laying motion bar 3 allowing actuator 51 insert centre bore 41 wherein and transversely to arrange, the drive surface of actuator 51 contacts in centre bore 41 with motion bar 3, and pilot hole 42 extends to the outer circumference surface of the hypomere 22 of pile 2 always.As shown in Figure 3,4, the return unit that foundation pile stablizes stiffening device comprises back-moving spring 32 and motion bar 3, and back-moving spring 32 resets for promoting actuator 51, is longitudinally located between mounting blocks 5 and back-up block 4, one end is against the bottom surface of mounting blocks 5, and the other end is against the end face of back-up block 4.Back-moving spring 32 resets for promoting motion bar 3, and it is enclosed within motion bar 3, and back-moving spring 32 one end is against on the inwall of back-up block 4, and the other end is against on the flange 31 of setting on motion bar 3.As shown in Figure 3, motion bar 3 is oval bar, and the outer circumference surface that flange 31 is located at motion bar 3 is integrated with motion bar 3.
In addition, when the pile 2 of this foundation pile needs to be arranged in darker ground or hole, as shown in Fig. 1, a same pile 2 can be connected again at the hypomere 22 of every pile post 2, or adjacent two pile posts 2 can be threaded connection, to extend the length of whole pile 2 by more pile posts 2.
When using this foundation pile, first need to carry out geological prospecting, then in the soil body, massif or mountain stone, get out installing hole, to insert pile 2, orientation and the degree of depth of each installing hole to be measured in advance, calculated the length needed for every pile post 2, guarantee that the hypomere 22 of pile 2 will be pressed at the bottom of hole.When the building on foundation pile because of earthquake or wind-force larger time shake, the deadweight of building produces downward downforce to pile 2, at this moment actuator 51 moves down to drive motion bar 3 to stretch out towards the outside of pile 2, be pushed against on the installing hole wall of each pile 2, strengthen the stability of ground pedestal.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
