SE518353C2 - Reinforcing device for walls - Google Patents

Abstract

The invention relates to a reinforcement device for fastening, in this context, tremendous loads to particularly weaker walls of the type wallboard coated stud frame, and to contribute to the ability of walls to resist horizontal forces. The reinforcement device comprises portions, which connect and reinforce the parts of the wall construction. Thus, exceeding a materials tensile strength can be avoided, and the forces are distributed over a larger area, wherein the resistibility thereof can be summarised to a larger resistance. In a certain embodiment the reinforcement device can be used for fastening in solid constructions, such as light concrete and hollow brick constructions.

A major disadvantage of the existing devices is that they cannot withstand being loaded with particularly large forces before the sheet material is broken, due to the fact that only one side of the wall is used.

As for the stiffness of a wall, you set the bars more closely as the need for stiffness is greater than in the nominal case wall, this usually means a distance between the bars that is 40cm. To strengthen existing walls, this presupposes that you tear off a board, and open the wall to be able to insert fl your studs, which are then re-lined with a board of normal quality fl Alternatively, you choose stiffer special boards on the market. Then you can keep the normal measurement between the bars, which is usually 60 cm. Also in this case you remove a disc. Another way is to supplement the wall with another standard board. This means that, for example, the length of a bathroom wall is usually reduced by twice the thickness of a slab, which normally means twice 13 mm, ie 26 mm. This can mean problems with, for example, dimensions of interior design, such as dimensions of bathtubs, which you may want to reinstall and which may then not fit in its previous place. A major disadvantage in this case is that any water pipe connections may end up inside the wall, so that no leakage can be detected, and if they occur, the water is forced into the wall by the sealing layer found on the surface of, for example, 10 15 20. . , ... 25. ... .run 518 3 53- *: Låiflši 3 wet room walls. In addition, all cases are labor-intensive and material-consuming and thus also very costly. Increased costs for the electricity and pipe installations usually arise if you change the number of rules and board layers regarding permanent walls.

THE INVENTION IN SUMMARY An object of the invention is to be able to load fasteners with much larger loads than the existing devices allow, and to be able to stiffen the walls of a wall. The reinforcing device can be used only for attachments, or only for stiffening, or combined, for example when extra large stresses are to be managed.

The present invention utilizes the fact that, for example, a plasterboard wall on a rule frame consists of a board on each side of a rule.

The reinforcing device is in its simplest embodiment a cylinder which is adapted to reach through one disc from its outside through the void created between the discs caused by the bolt, to the inside of the opposite disc. There, the cylinder is usually anchored by means of an adhesive joint. A fastening device has now been obtained with a lever which multiplies its ability to carry loads which are anchored at its end. The more the collars are directed vertically, the greater the importance of the cylinder's lever-forming design, especially mounted in a substantially vertical construction. What limits the bead-up capacity of the cylinder is the strength with which it is glued to the opposite plate, and the size of the abutment surface. n. ... 25 1. . . i »|.» | 518 353 a. .Oo 4 in the bushing through the upper disc. When the load is collapsed, the wire is torn off or the material in the board is crushed in the bushing. The distance between the discs can also be important.

The longer the distance, the longer the lever and thus the greater the resistance.

The cylinder must be so rigid that it does not bend.

Furthermore, the cylinder can be hollow in its length, and provided with holes through the part of its surface which grinds in the cavity of the wall.

Furthermore, you can, for example, apply an elastic fabric or foil around the cylinder, which acts as a mold for the possibly expanding masses that can be injected into the cylinder. These penetrate through the holes and fill up the form that encloses the cylinder so that you get a solid body that casts the cylinder and sticks to and fills in between the discs. This will be a reinforcing device that increases the rigidity of the wall against indentation, and in which you can mount, for example, screws and hooks which you can load with very large loads in this context.

As the surface that is glued to the opposite board and the radius of the reinforcing device in the bushing in the board that is being run increase, so does the performance.

In one embodiment, the device can be compared to a cylinder whose first and last part has a slightly larger diameter than the intermediate part. This is so that you can roll up the old cloth on the middle part so that it can follow through the hole occupied for mounting through the outer disc. As the end diameters of the spool-like cylinder increase, the performance increases. The cylinder end that is glued can in each embodiment be knurled for better adhesion. 10 15 20. . ..._ 25. .. »; >> | .... n 0 n u .. u. .n. n. .u n. n _. -. u. u u. - »u. u c: o z _. - u ~. - u ~ o e u .n .n. . . u v v u. .

In one embodiment, an elongate plate is mounted in the end of the cylinder to be glued to the opposite plate, in this way it is possible to get through as large an area as possible through the substantially circular hole.

In another embodiment, an additional elongate plate is included which is loosely threaded on the cylinder shaft. This plate can then be pulled towards the back of the first disc and glued there. This increases the strength properties of the board and thus the load-bearing capacity.

In cases where you have an elongated plate, the plates can either be oriented opposite each other, or with a 180 degree displacement, and then as a composite unit rotated to select fi in position for the entire revolution 360 degrees, depending on the direction and magnitude of the influencing forces and how for each occasion calculated how best to care for them.

In many of the different embodiments, the reinforcing device can be provided with a pre-cloth and thus reinforcing filling between the boards. 10 15 20. n.

. . . IQ q .- oc: 518 553 '6 In an embodiment where you want to improve the pressure-absorbing capacity of the wall in the horizontal joint, but dare not fill the cavity in the wall between the wall panels with more than the cylinder itself, you can design the part of the cylinder that do not glue to the rear board, slightly conical, and chamfer the hole through the board slightly conical and fill the gap thus created with a hardening joint-filling mass. This construction overcomes the horizontal forces to which the front panel may be subjected, also to the rear panel, and improves the pull-out resistance of the reinforcing device in the horizontal direction.

The cylinder tubes of all fastening devices which are intended for injection can, after possible injection of, for example, expanding mass, be provided with an adapting part between the inner cylinder area and a suitable hole for a possible screw.

The device can in certain embodiments, but especially as straight cylinders (12) and (35), or with a certain wire roll shape (18), also be applied in solid materials such as, for example, aerated concrete or hollow bricks.

The devices are then glued to the surrounding material along the entire length of the device, or as much of it as is desirable and possible. 10 15 20 ..Ii'25 11.1 »51 8 35:53 'I =" ï = ï' - '= 7 In one embodiment, one can dispense with a structural part, for example a cylinder, which enables attachment to the rear disc, without more traditionally reinforce only the front disc.

As an aid in the mounting of the device, especially in the hardening of any lines and joint masses, a fixing device belonging to the device can be used. This consists of a substantially circular cone, with a pin which can be inserted into the recess 16.

The cone has a sufficiently larger diameter than the device so that it is supported against surrounding surfaces where it can be temporarily fixed with adhesive and or pins.

It can also be provided with additional distances to compensate for differences in diameters. Such a spacer can also be mounted permanently. In cases where there are cavity filling means in the wall, such as rock wool insulation, and if you want to remove this, you can use a cavity cleaner developed for the device. It consists of a rod with an articulated upper part provided with a cutting edge. This tool is inserted through a hole in the disc, and is set in sharp rotation, for example with the help of a drill. The articulated part unfolds, revealing a volume with a radius equal to the length of the articulated part, and a volume length equal to how far you move the tool. 10 15 20 ß a »- n n: n | ævpa: 518 553 f: u .o -co 8 BRIEF DESCRIPTION OF THE DRAWINGS The drawings are marked: Fig. .., and a number, and shall be read in the order in which they Number follow it may be reversed.

. .N25. 518 353 1 2 THE INVENTION Referring to Fig. 1, the reinforcing device is shown as a cylindrical body 12. This embodiment is intended to be used for fastening fasteners, such as for example screws, for anchoring forces which are substantially perpendicular to the longitudinal section. . Figure 1F, shows the device fi- arrxi fi- ån, ie from the outside of the structure, which is usually a wall. Figure 2, shows the device from above.

A hole is made in the upper disc so that 12, provided with 14, can be inserted and attached to the rear disc.

Referring to Fig. 3, the reinforcing device is shown as a cylinder body 12, supplemented with substantially 14.

This design is intended to be used for fastening fasteners, such as screws, to anchor in relation to the longitudinal section substantially perpendicularly acting forces, however, 14 contributes to to some extent absorbing horizontal forces acting on the wall plate, the reinforcement device. Figure 3F, shows the device from the front, ie from the outside of the structure, which is usually a wall. Figure 4, shows the device from above.

A hole is made in the fi änire disc, so that 12, provided with 14, can be inserted and attached to the rear disc and the bushing. al ... 10 15 20. .... Referring to Fig. 5, the reinforcing device is shown as a cylindrical body 35, with a conical end. When 36 and 14 are made, this design is intended to be used for fastening fasteners, such as for instance screws, in order to anchor, in relation to the longitudinal section, forces acting substantially perpendicularly. However, 14 contributes to a considerable extent to absorb horizontal forces acting on the wall plate, and significantly improves the pull-out resistance in the horizontal plane, for the reinforcing device.

The figure SF, shows the device fi ami fi ån, ie from the outside of the structure, which is usually a wall. Figure 6, shows the device from above.

Assembly as in Fig.3, with addition 36, and 12 is changed to 35.

Referring to Fig. 7, the reinforcing device is shown as a cylindrical body 18, wire roll-shaped. The thread spool shape is used when you want a narrower middle body. As 20 and 15 are given a larger surface area, this design, intended to be used for fastening fasteners, such as for example screws, carries increasingly considerable forces, anchoring in relation to the longitudinal section, substantially perpendicularly. Helps to absorb to some extent horizontal forces acting on the wallboard, and significantly improves the pull-out resistance, of a larger 20, in the horizontal plane, for the reinforcing device. In cases where 18 is used, this can be provided with 21. Figure 7F, shows the device from the front, ie from the outside of the structure, which is usually a wall. Figure 8 shows the device from above.

Mounting as in Fig. 3, but 12 is changed to 18 and 14 to 25. 10 15 20. . , ... 25. ... || .-- 518 353 f; Referring to Fig. 10, the reinforcing device is shown as a cylindrical body 18, wire roll-shaped. The thread spool shape is used when you want a narrower middle body. On this intermediate body you can apply form cloth 27, when you intend to apply 26. After stepping the front cloth 27, which can be likened to a piece of a very elastic sock, on the narrower middle part of the cylinder body, you glue the cloth in points 29, with convenient a fast-melting lirn of the traditional hot-melt adhesive type.

This is so that the sealant, for example polyurethane foam, fills the mold and does not run out of it. As 20 and 15 are provided with a larger surface area, the design is intended to be used for fastening fasteners, such as, for example, screws, in order to anchor, in relation to the longitudinal section substantially perpendicularly acting, increasingly considerable forces. 25 and 26 contribute to a considerable extent to absorb horizontal forces acting on the wallboard, and significantly improve the pull-out resistance, by a larger 20, with the addition of 26, in the horizontal plane, for the reinforcing device. In cases where 18 is used, this can be provided with 21. Figure 9F, shows the device from the front, ie from the outside of the structure, which is usually a wall. Figure 9 shows the device from above, when applying 26 by means of 28. Assembly: A hole is made in the upper disc fitting the cylinder body 18. The diameter of the hole must correspond to the upper part 23 of the thread spool cylinder and the rear part 20. Glue or sealant to the joints 14 and 25 is applied. A mold cloth is threaded over the middle part of the cylinder. The cylinder body is inserted into the hole of the fi-front disc and glued to the rear disc.

Cylinder and mold are filled with e.g. polyurethane joint foam 26. Referring to Figs. 15 and Fig. 16, the reinforcing device is shown in a side view of the device in an embodiment where the rear part of the device is elongate, and as large as one possibly the thread can be threaded through the insertion hole in the front disc, and the movable part, which is similar to the rear part, is shown and can be pulled along the cylinder to the back of the front disc. In addition, the cylinder body and the part that fills the hole in the disc bushing are shown. The cylinder body 32, with its front part 30, and its rear part 31, forms a fixedly joined unit. The beveled sides of 30, give you a restraining part, especially when you pull 34, towards the back of the upper disc. The fact that the other sides of 30 are not bevelled is due to the fact that the surfaces are expected to absorb forces which are substantially perpendicular to 15, and thus horizontal forces which want to surface the fastening device are avoided. The oval shape of 31 and 34 contributes to giving a maximum large surface area on these parts which are to be passed through the opening in the inner disc, which in turn gives maximum drying strength and fastening effect. The size of 30 is also important for these effects.

Fig. 15 F Shows the device in Fig. 15 and Fig. 16, Figs. 11 and 12 show the device in Fig. 15 and Fig. 16, from above.

Assembly: The composite unit 30,32,3l, with the movable part 34, close to 31, is inserted into the hole that fits 30. The hole that fits 30 can, for example, be taken up with a traditional hole cutter, and be chamfered with a fi l , so it fits the elliptical 10 15 20. '2. out ... 518 353 16 contour that 30 has. The elongate plates 31 and 34, are held parallel along each other and inserted into the hole with the part projecting furthest from the center axis of the cylinder, first. Glue has already been applied to the part 31 which is glued to the rear gypsum board, and where applicable to the glue joint 25, on part 30, and on the part 34 which is glued to the back of the upper board. This latter line, also glues together 30, with 34. The described composite unit is pressed against the rear gypsum board, and is xered there with the aid of the x-pin. On the straps you can now thread on locks, which can be stuck, or just stay until the joints have hardened. If a hollow cylinder body has been used, it is possible, if necessary, to reduce its hole with an adapter 21. in.

This increases the ability of the reinforcing device to give, for example, a wall increased ability to absorb larger horizontal and vertical loads, in the area affected by forces, which in turn affect the fastening device.

Fig. 18 F Shows the device in Fig. 18, Fig. 14 shows the device in Fig. 18, from above.

Assembly: Same as for Figs. 15 and 16, but with the addition that the molding cloth 27 is put on, before the parts 34 and 31 are brought together.

The molding fabric must also be attached, suitably with a fast-flowing melting line of conventional type, to said parts, in order to be stretched when 34 is pulled to its position against the back of the front disc. See Figs. 18, 18F and 14.

Referring to Fig. 13, it is shown how the pre-reinforcement device is mounted according to Fig. 17, where the loose part, 34, has been able to rotate 180 degrees. The instructions for Figs. 15 and 16 are followed, but with the difference that the tension straps are wound half a turn around the cylinder body. When you pull 34, to its position towards the back of the upper disc, 34 rotates, half a turn. 10 15 518 355 '; ==' ~ ~ 1 8 Fig. 19 shows when you continue to inject sealant 26. This must be prepared by mounting a molding sheet 27, before joining 34 next to 31, insert through the fi yearling through it. the occupied hole through the upper disc. Since 34, will rotate half a turn, one must hold 31 and 34 in this the final position when attaching the forming fabric, preferably with a fast-melting melting line. Suitable framing points are: See Figs. 19 and l9F. 1. fold up the molding and fasten to 34, close to the cylinder body, but not against. 2. fold up the molding and fasten to 3 1, a piece of attachment point, at the rounded end, close to the cylinder body. 3. pull the cloth over the corner of 31, and fasten there.

The form fabric is now attached at four points, and rests on the cylinder body, as the pre-reinforcement device is mounted in the wall, and can catch, for example, polyurethane joint foam. 10 15 b ~ n f n s »in ... 20 a o | a »safu» 518 555 = 19 Referring to Fig. 20, the reinforcing device without the cylinder-shaped intermediate body is shown. The back plate is rectangular, or essentially rectangular. A hole is made in the front disc, which has a suitable size, suitable for 37 and 38. The device can be rotated in the selection fi ° in the direction of the entire turn 380 degrees. The edges of the hole are chamfered to fit 30, which is the alternative, a loose fi lower part. The plate 38, is provided with glue and connected to 30, which may be provided with glue 25, via the strips 33. The plate is inserted into the hole, which is made possible, among other things, by the length and flexibility of the strips. The loose part 30 is pressed into the hole and fills it. The plate 38, is pulled tightly together with 30, and the back of the front disc, and can be där xxed there with locks that are threaded on the straps. In addition to Fig. 20 showing the reinforcing device in this transformer, from the side, when one has chosen to place with its elliptical front face with the longer diameter horizontally, Fig. 21 shows the device seen from the side, contracted, oriented as in Fig. 20.
