Abstract
The utility model provides a spiral ground anchor base for a building. The spiral ground anchor base realizes rapid and safe construction and reduction of building cost. The spiral ground anchor base comprises a spiral anchor rod pillar and basic steel pipe components. The spiral anchor rod pillar is formed through cold twisting of a steel plate with the yield strength of 400MPa and is spiral leftwards and rightwards. The top of the spiral anchor rod pillar is provided with a flange plate and the tail of the spiral anchor rod pillar is provided with edges on the left and right sides through grinding and is in the shape of a drill bit. The basic steel pipe components are made of carbon steel pipes. The basic steel pipe components also comprise welded side wings and the top flange plate. The flange plate is provided with a rectangular hole in the middle. The spiral anchor rod pillar can pass through the hole in a rotary manner and thus can be inserted into the deep of formation vertically. The flange plates of two parts overlap with each other and are fixedly connected with a flange plate of the ground building through bolts.
Description
Technical field
The utility model relates to a kind of screw anchor basis.
Background technology
The building foundation of civil construction, industrialized agriculture, installation street lamp, billboard, direction board, steel house etc. all adopts the reinforced concrete foundation pouring procedure.
In the concrete foundation construction, in order to make cast-in-situ concrete, need to excavate, the facility of compacting, formwork supporting plate etc., and because the gravity of foundation is larger, soft or have the place of water all to be not suitable for construction, the more cities and towns of underground pipeline are not only inapplicable, process the problems such as welding but also can produce roach.
Concrete foundation has the operation of formwork supporting plate, form removal, cast, maintenance, needs consuming time month.
The utility model content
Main purpose of the present utility model is: utilize spiral self-locking condition principle, a kind of screw anchor basis is provided.
Secondary objective of the present utility model: the one, can change the job practices on reinforced concrete building basis, the 2nd, protect environment and shortened the construction period, the 3rd, the simple and safe property of constructing is high, without roach.
Technical solution adopted in the utility model:
The screw anchor basis comprises: Screw Anchor roofbolt, basic steel tube component; The Screw Anchor roofbolt adopts cold the twisting of the steel plate of yield strength 400Mpa to form left-handed or dextrorotation; The basis steel tube component adopts carbon steel pipes to make, with flank.
Screw Anchor roofbolt in the screw anchor basic components is that the cold stubborn pitch of professional equipment equates, and is left-hand screw or the right-hand screw cylinder of same axis, and the installation connecting element of same material is welded in the spiral anchor rod column top, and afterbody puts the first edge on a knife or a pair of scissors and is the drill bit shape.
Basic steel tube component in the screw anchor basic components also comprises flank and the top flange dish of welding, and rectangular opening is left at this flange center, and the Screw Anchor roofbolt rotates through from this hole, guarantees that spiral anchor rod can vertical insert into stratum depths.
Building field is not only used on the screw anchor basis, can also use in fields such as agricultural, forestry, water conservancy, advertisements; Use that the screw anchor basis can greatly be improved efficiency of construction, saved time, reduction of erection time, reduction cost of labor.
Description of drawings
The screw anchor basis is comprised of shown in the accompanying drawing Screw Anchor roofbolt, basic steel tube component.
Fig. 1 is screw anchor basis spiral anchor rod cylinder
Fig. 2 is screw anchor basis steel tube component
Fig. 3 is screw anchor basis composite diagram
Fig. 4 is screw anchor basis Screw Anchor roofbolt plan

The specific embodiment
The above structure steel material (seeing accompanying drawing 1) of yield strength 400mpa is selected on screw anchor basis (seeing accompanying drawing 3), screw anchor foundation anchor post, and basic steel tube component is selected Q235 carbon steel material (seeing accompanying drawing 2).
Screw Anchor roofbolt main body spiral is processed by special equipment, become the spiral component of left-handed or dextrorotation, the top is for installing the connector of same material, afterbody is drill bit shape grinding sword (seeing accompanying drawing 4 upper figure), steel tube component top, basis is the flange of middle opening, and the bottom is the steel pipe (seeing accompanying drawing 5) with assistant, and then electrode is processed, form anticorrosion corrosion resistant material, guarantee its application life.
After determining the building foundation position, first basic steel tube component 90% is pressed into soil layer, reserves 10% as adjusting the space, then the opening part of Screw Anchor roofbolt from basic steel pipe upper flange dish vertically inserted, use again pressure at right angle rotating screw anchor pole post, make it pass steel pipe insert into stratum depths.The supercharging in steel pipe of the first half of spiral increases the earth anchor uplift resistance; The latter half is anchored at below the frozen soil layer, by the latching characteristics of spiral, eliminates the unbalanced sedimentation of ground, guarantees the stability of building structure.
Screw Anchor roofbolt connector, basic steel tube component flange are fixedly connected with bolt with surface structures member flange on the basis.
Claims (3)
