Abstract

The utility model relates to a fastening means for fixing a power device and a device base, comprising a square head foundation bolt (12), an anchor plate (7), and a baffle block (10). The foundation bolt (12) traverses through the anchor plate (7), and is rotated by 90 DEG and is spaced by the baffle block (10). A bolt is fastened through a nut, and the anchor plate (7) and a power device base (1) are fastened together. The fastening means is advantageous in that a power device base (1) and a device base (3) can be stably connected together, and a foundation bolt (12) can be replaced, and thereby the problems that the replacing of a foundation bolt is inconvenient when the foundation bolt is damaged, and a conventional fastening method requires two times of concrete watering can be resolved.

Description

A kind of securing means

Technical field

The utility model relates to a kind of securing means, relates in particular to a kind of installation securing means that is used for power equipment and basic fixed.

Background technique

Power equipment in use, there is very large dynamic load on the basis relatively.For guaranteeing the power equipment reliable operation, require equipment to be fixed on the dynamic foundation very securely.

Traditional method adopts the directly buried type stone bolt to fix.Be about to stone bolt and imbed in the concrete on basis, equipment and basis are tightened to one with nut and stone bolt.Rely on the outer surface of stone bolt and the vibration of concrete frictional force absorption equipment.

During construction; Considering the difficulty of installing and locating and construction casting, generally all is the hole of backup land foot bolt when building on the bulk basis, then power equipment pedestal and stone bolt is placed on the bulk basis together; After stone bolt had good positioning, carry out the final grouting concrete again.See shown in Figure 1.

Stone bolt such as Fig. 2 commonly used show.Because processing nut screw thread is difficult for, stone bolt is generally used the Q235 round steel.In particular cases adopt Deformed Steel Bars.

Conventional fixed mode shortcoming:

Based on the fixing power equipment of this technology; Because stone bolt and concrete frictional force are less; Secondary is built and is difficult for combining firmly with original mass concrete, and reason such as construction quality is wayward, therefore; The phenomenon that stone bolt becomes flexible or comes off in the using process takes place easily, can cause equipment to use when serious.

With the present invention similar be ordinary casing-anchor slab stone bolt.After the sleeve pipe of stone bolt and bolt were made respectively, under casing elder generation is back cover not.Before using bolt from the under casing bottom threading, anchor slab and under casing top board are adjacent to, and find the center, fix bolt and cover plate, cover plate and sleeve pipe spot welding then, at last the under casing back cover, bolt has just become an integral body with sleeve pipe like this.When the pouring basis, imbed in the basis as the direct-burried bolt, when centering is installed, to knock the solder joint at cover plate and sleeve pipe place open, bolt just can be free movable in sleeve pipe, and anchor slab also can be movable under casing.Behind the final grouting, they all will be shut fixing.

The shortcoming of this method is that stone bolt will be shut in the basis after construction was accomplished.If problem such as be damaged, can only all parts be dug out and change.

The model utility content

The purpose of the utility model is to solve fixedly securing of power equipment basis, in addition, when stone bolt is damaged, can change.

In order to achieve the above object; The technological scheme of the utility model has provided a kind of securing means; Comprise square countersunk head stone bolt, anchor slab, block, it is characterized in that: square countersunk head stone bolt (12) one ends are the rectangular countersunk head, and the other end is a screw thread, and anchor slab (7) is provided with the corresponding oblong openings of rectangular countersunk head with square countersunk head stone bolt (12); Said rectangular countersunk head is positioned at said oblong openings below, and the two long side direction is orthogonal; The below of anchor slab (7) is provided with under casing (9), is provided with the block (10) of the rectangular countersunk head rotation of the square countersunk head stone bolt of restriction (12) in the under casing (9); The screw thread end of square countersunk head stone bolt (12) cooperates with nut.

The beneficial effect of the utility model is:

(1) adopts this programme, when construction, alleviated the work of anchor location greatly, reduced difficulty of construction.

(2) stone bolt is replaceable, for the working service of equipment provides convenience.

Wherein: 1-power equipment pedestal, 2-stone bolt, 3-concrete foundation, the concrete foundation of 4-final grouting, 5-cover plate, 6-sleeve pipe, 7-anchor slab, 8-stone bolt fixture block, 9-under casing, 10-block, 11-fixed bearing, the square countersunk head stone bolt of 12-.

Embodiment

Below in conjunction with accompanying drawing 4-6 the utility model is done further to describe.

As shown in Figure 4; Before placement of concrete basis 3; With fixed bearing 11 power equipment pedestal 1 is supported leveling earlier; Accomplish the welding processing of cover plate 5, sleeve pipe 6, anchor slab 7, under casing 9 and block 10, before the grouting, entire sleeve anchor slab device is fixedly connected with equipment base 1 (can airtight weldering dead).On pedestal, during fixed sleeving under casing 9, guarantee that anchor slab 7 oblong aperture and pedestal 1 bolt hole satisfy positioning relation.

A kind of structural type of stone bolt 12 is seen Fig. 5, and an end is the rectangular countersunk head, and the other end is a screw thread.7 perforates of anchor slab are rectangular, can turn 90 degrees when countersunk head revolves just in time through the countersunk head end of stone bolt 12, will blocked and can not pass through by the hole of anchor slab 7.After sleeve pipe under casing 9 grades and pedestal 1 are fixing, can stone bolt 12 countersunk head ends be put into anchor slab 7 belows from the pedestal screw, revolve and turn 90 degrees; Then countersunk head is spacing by anchor slab 7 holes, can not extract out, and spacing by block 10; Can not rotate again, at this moment, tighten stone bolt through nut, spring pad etc. at other end of stone bolt; Anchor slab sleeves etc. are closely linked together with pedestal 1 by the stone bolt pretension.Grouting finishes, and after concrete reached preset strength, foot bolt 12 securely made equipment firmly be connected with ground once more.

Because stone bolt 12 no longer exposes and imbeds in the concrete foundation, but is sealed in Equipment Foundations and the sleeve pipe 6.When stone bolt 12 is damaged, can directly take out replacing.
