Description

High stability rag bolt

[ technical field ] A method for producing a semiconductor device

The utility model relates to a technical field of fastener, especially rag bolt's technical field.

[ background of the invention ]

The anchor bolts can be divided into fixed anchor bolts, movable anchor bolts, anchor expansion anchor bolts and bonding anchor bolts. Wherein the utility model is divided into the following parts according to different shapes: l-shaped embedded bolts, 9-shaped embedded bolts, U-shaped embedded bolts, welded embedded bolts and bottom plate embedded bolts.

The installation method comprises a one-time embedding method and a reserved hole method. Primary embedding method: when concrete is poured, the anchor bolts are buried. When the high tower is controlled by overturning, the foundation bolt is preferably embedded once. Preformed hole method: the equipment is put in place, cleans the hole, puts the rag bolt into the hole, and the reuse is higher than former basis and is poured with the fine aggregate concrete that does not have the shrink one-level after the equipment location alignment, and it is closely knit to tamp. The distance from the center of the foundation bolt embedded once to the edge of the foundation is not less than 2dd, the diameter of the foundation bolt is not less than 15mmd and not more than 20, the diameter of the foundation bolt is not less than 10mm, the width of the foundation bolt is not less than half of the width of the anchor plate plus 50mm, and when the requirements cannot be met, appropriate measures are taken to reinforce the foundation bolt. The diameter of the foundation bolt for the structure is not smaller than 20 mm. When the anchor bolt bears earthquake action, double nuts are adopted for fixing, or other measures for effectively preventing looseness are adopted, but the anchoring length of the anchor bolt is increased by 5d compared with that of the anchor bolt without earthquake action.

The contact area between the chassis of the existing bottom plate embedded bolt and concrete is small, and the requirement of high stability in some projects cannot be met.

[ Utility model ] content

The utility model aims at solving the problem among the prior art, provide a high stability rag bolt, have very high stability, prevent that rag bolt from being extracted.

In order to achieve the purpose, the utility model provides a high stability rag bolt, including the bolt body, the top of bolt body is equipped with the screw thread section, the bottom of bolt body is equipped with the chassis, be equipped with the gusset plate between bolt body and the chassis, a plurality of draw-in grooves have evenly been seted up to the periphery on chassis, install the stationary blade on the draw-in groove.

Preferably, the fixing plate comprises a mounting edge, a slot is formed in the mounting edge, and the slot is inserted into the slot.

Preferably, two side edges of the fixing sheet adjacent to the mounting edge are provided with side bends, a reinforcing plate is arranged on the side edge of the fixing sheet opposite to the mounting edge, and the reinforcing plate is connected with the two side bends.

Preferably, the outer surface of the thread section is provided with a nano ceramic coating.

Preferably, the base plate is circular, and the clamping grooves are uniformly and annularly formed in the peripheral edge of the base plate.

Preferably, the depth of the slot is smaller than the depth of the slot.

The utility model has the advantages that: the utility model discloses a set up a plurality of stationary blades, increase the area of contact of rag bolt embedded part and castable, prevent effectively that rag bolt from being extracted, improve rag bolt's stability; the fixing piece is detachably connected with the foundation bolt, so that the foundation bolt is convenient to transport; the intensity of stationary blade has been improved in the setting of bending of stationary blade, prevents that the stationary blade from taking place to warp.

The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.
