Description
Technical field
The utility model relates to a kind of fastening or engineering element that fixed equipment is used, and in particular, the utility model relates to a kind of stone bolt of vibrations than large equipment that be used to install.
Background technique
General stone bolt is in order to fixed equipment among the concreting basis time is embedded in the basis.Equipment is installed and is mainly contained two types with stone bolt traditionally:
One of which is the placement of concrete basis at equipment to be installed place, and on the basis, reserves anchor (bolt) hole, treats to install when equipment is installed stone bolt again, after the equipment adjustment is qualified, expects second pouring with pea gravel concreten or from levelling grouting again.Such bolt is not high to the required precision in pre-embedded anchoring bolts hole, but can only be used for stressed less position or less important position.
They are two years old; Be the direct-burried stone bolt, require stone bolt to be fixed on the bolt frame inspection bolt center line and the qualified after-pouring concrete of absolute altitude at equipment to be installed place; And in the concreting process, note the variation of inspection bolt center line and absolute altitude; In time proofread and correct simultaneously, the equipment of treating carries out the handing-over of bolt when installing checks and accepts, and secondary is built the grouting material after equipment is installed adjustment.Such bolt usually is used for stressed bigger position, is that the center permissible error of requirement pre-embedded anchoring bolts is ± 2 millimeters to the installation precision of bolt among the GB50204-2002 " concrete structure engineering construction quality acceptance specification ".
So high required precision has increased the difficulty of civil engineering, and especially in concreting process, the shaking force of concrete impact force and vibrating spear is all installed bolt and produced considerable influence.Some engineering is to find just that when civil engineering specialty and equipment are installed specialty handing-over examination bolt position and absolute altitude deviation are excessive; The correction and stone bolt does not allow to get angry; So; Can only the bolt hole of equipment be enlarged, with the installation precision of assurance equipment, and this correction mode often has a negative impact to equipment operation.
For guaranteeing that the equipment smooth installation carries out and guarantee the installation precision of equipment, can finely tune stone bolt when being preferably in erection unit, therefore, adopted the tup bolt in some engineering.Described tup bolt belongs to a kind of special shape of direct-burried bolt; Mounting type as the one of which is: when concrete foundation is built, special moulding box (anchor plate) is embedded in the basis; Like this, can when erection unit, dismantle or a certain amount of adjustment stone bolt.But the processing of tup bolt is difficulty relatively, complex process, and most owners are reluctant to adopt.
The model utility content
The utility model technical problem to be solved remedies the defective of above-mentioned existing technology exactly, and a kind of adjustable ground foot bolt of vibrations than large equipment that be used to install is provided for this reason.
The technique effect of the utility model is achieved through following technological scheme:
A kind ofly be used to install the adjustable ground foot bolt of vibrations, comprise screw rod and be arranged on the outside sleeve pipe of said screw rod than large equipment; The upper end of said sleeve pipe is provided with the last anchor slab that has center hole, and the lower end of said sleeve pipe is provided with the following anchor slab that has center hole; Said screw rod stretches out said upper end of going up the anchor slab center hole and is provided with tightening nut, welding shearing piece on the described upward anchor slab; Said screw rod stretches out the said lower end of anchor slab center hole down and is threaded with setscrew nut, and described setscrew nut is welded on the said bottom of anchor slab down.
The said diameter of going up center hole on the anchor slab equals the diameter of said sleeve pipe.
The diameter of center hole is greater than the diameter 1～3mm of said screw rod on the said anchor slab down.
The beneficial effect of the utility model is:
(1) only need common engineering elements such as steel pipe, steel plate, nut just can accomplish processing, technology is simple, saves human and material resources, time.
(2) can reliably be connected with fixing frame, have certain adjustment amount, thereby guarantee precision of equipment installation.
(3) can be after detecting himself installation precision equipment in place, and after the detection facility installation precision pouring grouting material, both guaranteed precision of equipment installation, need not to enlarge the bolt hole of equipment bay again.
(4) setting of said shearing-resistance blocks has strengthened the equipment that is mounted and basic integrity, can guarantee to shake the normal operation than large equipment.
