RU219384U1 - ANCHOR WITH SLEEVE - Google Patents

Abstract

The utility model relates to elements of building structures and building materials, and more precisely, to anchor devices designed for fastening light (aluminum, wood, plastic) structures to solid bases (concrete, brick) due to mechanical wedging of the sleeve. The product is an anchor with a sleeve, consisting of a screw with a partial metric thread, a hollow sleeve with projections and cuts, a flare nut with a partial metric thread and projections. Due to the long spacer zone of the hollow sleeve and the free through hole in the flare nut, the anchor with the sleeve can be used in any solid base, which makes its application universal. The screw is partially threaded, and the flare nut is also partially threaded. Hidden fastening is created due to the countersunk shape of the screw head. The hidden shape of the cap during installation allows you to delve into the attached object without visible protrusions. The product differs in that it has a bulge in the form of a washer on the screw head, the screw has an incomplete metric thread and a countersunk head with a slot type Z at the same time, the cone nut has a threaded part and a hollow part at the same time, the hollow sleeve has a long spacer zone, the cone nut has three projections for fixing in the hollow sleeve. A utility model can be manufactured on an industrial scale for subsequent use by end users when performing repair, installation, and construction work.

Description

Field of technology to which the utility model belongs

The utility model relates to elements of building structures and building materials, and more precisely, to anchor devices designed for fastening light (aluminum, wood, plastic) structures to solid bases (concrete, brick) due to mechanical wedging of the sleeve.

State of the art

There are many types of metal anchors for fastening in solid bases.

Thus, according to the patent of the Russian Federation for utility model No. 42840, a sleeve anchor is known, containing a sleeve, in the hole of which there is a fixing element and a rope covered by a fixing element made in the form of a spiral, characterized in that on the sleeve along its ends flanges are made, partially overlapping the opening of the sleeve, and the fixing element is located between the above-mentioned flanges.

In addition, according to the patent of the Russian Federation for utility model No. 24694, a sleeve anchor is known, containing a sleeve in which a cable is placed, and between them - a latch, characterized in that the latch is made in the form of a tape or tube carrying locking elements that can interact with the inner surface of the sleeve and with the cable. The fixing elements can be made in the form of metal particles placed on the tape or on the tube, as well as in the form of metal balls placed on the tape or on the tube.

The disadvantages of these products are the features of the application - they are divided according to the application in a particular base (either foam concrete, or concrete with cracks, or concrete without cracks, brick or solid, or hollow), that is, they are not universal. In addition, known anchors after installation have a visible part in the form of a protruding stud with a nut or bolt, and do not allow hidden fastening. Also, their production is quite costly, there is no way to reduce such costs.

Disclosure of the essence of the utility model

The objective of this utility model is to develop a product that can be used in any solid base, which makes its use universal, has a hidden fastening.

The product is an anchor with a sleeve, consisting of a screw with a partial metric thread, a hollow sleeve with projections and cuts, a flare nut with a partial metric thread and projections.

Implementation of the utility model

Due to the presence of a sleeve with a circular cross section, the attached object fits snugly with the walls of the through hole along the entire length of the anchor, which does not allow the attached object to become loose under dynamic loads. The design of the anchor allows you to fix the object, having access from one side (wall panel, beam or plinth), install the anchor with a sweat (hidden fastening), use it in all types of bases, including foam concrete and hollow brick.

The anchor consists of

screw 1, on which a partial metric thread 3 is applied, on the smooth side 2 of the screw there is a countersunk head 4 with an extension for flush installation, on the head cone there is a protrusion with a diameter of 10 mm in the form of a washer 5, on the head there is a slot 6 type Z No. 3 GOST 10753-86;

hollow sleeve 7 of circular cross section with technological cuts 9 and protrusions 8, which create an effective spacer zone of the anchor and are necessary to prevent the flare nut from turning during installation. The protrusions 8 serve as a fixing element of the anchor in the hole.

flare nut 10 with a through hole with a partial metric thread 11, three protrusions 12 in the form of guide rails, which are necessary for fixing the flare nut 8 in the hollow sleeve 7 and to prevent the flare nut from turning and tightening direction during installation. Portion of the flare nut hole is hollow (13).

At the moment, there are many types of metal anchors for fastening in solid bases. All of them are divided according to their application in a specific base, either foam concrete, or concrete with cracks, or concrete without cracks, brick, or solid, or hollow. Due to the long spacer zone of the hollow sleeve and the free through hole in the flare nut, the anchor with the sleeve can be used in any solid base, which makes its application universal.

The screw has a partial thread with a length of not more than 50 mm, as well as a cone nut has a partial thread.

All known anchors after installation have a visible part in the form of a protruding stud with a nut or bolt. The anchor with a sleeve is installed in the through hole of the attached object with a diameter of 10 mm and a length of 50 to 200 mm, and at the same time has

hidden fastening. Hidden fastening is created due to the countersunk shape of the screw head. The hidden shape of the cap during installation allows you to delve into the attached object without visible protrusions.

During installation (tightening the screw), the hollow sleeve rests against the washer on the cap with a diameter of 10 mm, which allows the countersunk sleeve to expand.

The above makes the anchor with a sleeve a universal fixing element.

The product is different in that:

1) has a bulge in the form of a washer with a diameter of 10 mm on the screw head;

2) the screw has an incomplete metric thread and a countersunk head with a slot type Z at the same time;

3) the flare nut has a threaded part and a hollow part at the same time;

4) the hollow sleeve has a long spacer zone of at least 20 mm;

5) the flare nut has three projections for fixing in the hollow sleeve.
