Definitions
- This invention relates to a metal hanger for use in the building industry, in particular for connecting horizontally extending members such as roof trusses or joists to vertically extending, supporting masonry.
- Roof truss hangers and joist hangers are widely used in the building industry, but the hangers currently in use are of a construction such that working loads to which the supported roof trusses or joists may be subjected, are only safely achievable when there is a restraining body of masonry on top of the hanger. If this requirement cannot be met, as may be the case for example at the junction of a roof ridge and a supporting wall, relatively complex solutions, such as double trusses coupled by tie beams, have to be employed to enable safe load bearing.
- a primary aim of the present invention is to provide a solution to these problems.
- a metal hanger for connecting horizontally extending structural members to vertically extending, supporting masonry, comprising a member having an inverted, generally L-shaped part for in engagement with the supporting masonry with a first limb extending over the top of a course of brickwork or blockwork and a second limb extending down the internal face of the masonry, and integrally connected with the aforesaid second limb an inverted, generally U-shaped part for locating the end of a horizontally extending structural member, wherein stiffening means are incorporated substantially to prevent bending of the L-shaped part at the connection between the first and second limbs and the arrangement is such that in use the hanger is able to support the load of the horizontally extending structural member without requiring a body of masonry above it
- a hanger as aforesaid includes a lip on the outboard edge of the first limb which in use hooks over the supporting masonry wall and ensures that the second limb lies flat against the internal face of the wall
- a hanger according to the invention does not prevent further masonry being built up on top if required but does enable the hanger to be used without the additional masonry in place
- the U-shaped part is formed from spaced apart side cheeks and a base on which, in use, the end of the horizontally extending structural member will rest and the base extends on either side of the spaced apart cheeks to form, in use, two horizontal wings which are attached to or extend integrally from the lower edge of the second limb of the hanger, to provide lateral strengthening thereof
- a hanger embodying the invention can be adapted to support two horizontally extending side-by-side structural members, by providing three equally spaced apart cheeks, the middle one of which separates the two side-by-side members, and the two ends of which are sandwiched between the middle cheek and the two outer cheeks of the hanger
- a method of building a masonry wall from building blocks using a hanger constructed in accordance with the invention, to support a horizontally extending structural member may comprise the following steps;
- Fig 1 shows one embodiment of hanger in perspective, when in use
- Fig 4 shows a still further modification.
- Fig 5 shows a hanger embodying the invention adapted to support a double beam or double joist
- Fig 6 shows in more detail how a hanger such as shown in Fig 1 or Fig 5 is built in to blockwork
- Fig 7 is a perspective view showing a typical application for a hanger of the invention.
- the hanger illustrated in Fig 1 has an inverted, generally L-shaped part 10 integrally connected with an inverted, generally U-shaped part 12. Both parts are made of sheet metal, typically sheet steeel.
- the part 10 locates over the top of a vertically extending masonry wall 14, with limb 16 lying against the top face and limb 18 against the internal vertical face.
- the part 12 is integrally connected with the front face of the limb 18, as by welding.
- This part 12 serves to locate one end of a horizontally extending structural member 20, such as a joist or the bottom member of a roof truss. Commonly, the other end of the horizontal structural member will be similarly supported.
- the hanger corresponds to the construction of a conventional roof truss or joist hanger, which for safe working practice requires a body of masonry to be built on top of it.
- the hanger in accordance with the invention also includes two stiffening elements 24, 24A of strip-like form, welded in position to interconnect the top edge of the part 12 with the top face of the limb 16 of the part 10, and a dependent lip 22 along the back of the limb 16 of the part 10
- the lip 22 in use hooks over the back of the supporting masonry wall 14 to ensure that the limb 18 of the part 10 lies flat against the internal face of the wall, thus to some extent relieving the bending moment between the limbs 16 and 18, while the elements 14, 14A serve positively to prevent bending between the limbs 16 and 18.
- the above described hanger in accordance with the invention will safely support all normal roof trusses and floor joists without requiring the restraint of additional masonry on top of it. This avoids the need for complex solutions where no space for additional masonry is available.
- the elements 24, 24A are readily accommodated, if necessary, at joints between building blocks or courses of building blocks.
- the hanger will be manufactured in a range of sizes suited to differing masonry wall thicknesses and differing dimensions of horizontal members to be supported and the loads to be taken by these horizontal members, which will typically be roof trusses and/or floor joists.
- the span of the U-shaped part 12, marked as 75mm in width will in practice be suited to the thickness dimensions of the roof truss or joist to be supported, whilst the length of the limb 16 will match the thickness of the masonry wall 14. In all instances, it is ensured that the resistance to bending of the hanger afforded by the stiffening means is sufficient to resist the forces imposed by the loads supported by the hanger.
- Fig 2 shows a modification of the metal hanger of Fig 1 in which the part 10 has the same width as the part 12, and the lip 22 along the back of the limb 16 is omitted, the building operator being relied upon to fit the hanger closely against the internal face of the wall 14.
- Fig 3 shows a further modification in which the greater width of the part 10, as compared to the width of the part 12, is utilised to enable L-shaped stiffening strips 26, 26A to be employed, extending around the corner of the part 10 between the limbs 16 and 18 in planes parallel to the sides of the U-shaped part 12, as illustrated but not essentially the outside edges of the part 10.
- This modification also serves to make it clear that, although in connection with the embodiment of Fig 1 the stiffening elements are stated to be welded in position, it is alternatively possible for the stiffening elements to be integrally formed with one of the parts 10, 12, part 10 in the case of the Fig 3 embodiment. Moreover, only one, or more than two such L-shaped stiffening strips may be provided, if desired.
- Fig 4 shows a still further embodiment, in which the stiffening elements 24, 24A or 16, 26A are replaced by a stiffening bulge 28 or analogous deformity integrally formed, as by pressing, into the part 10 at the connection between the limbs 16 and 18 of this part.
- the deformity stiffens the part 10 by creating a discontinuity in the bending line between the limbs 16 and 18, sufficient to provide the bending resistance necessary to resist the forces imposed by loads supported by the hanger.
- Fig 5 three spaced apart plates 30, 32 and 34 are shown welded to a base plate 36 which comprises an outwardly bent flange of a backplate 38 to which the upright edges of the plates 30, 32 and 34 are also welded.
- the backplate 38 is bent over to form an integral upper flange 40, the outboard end of which is bent down to define a lip 42 for hooking over the bricks or blocks such as 44 of a masonry wall from which the hanger is to support a pair of horizontally extending members 46, 48 such as the two beams of a double beam or the ends of a pair of adjacent roof trusses.
- wings 13 and 15 are shown as aligned extensions of the base of the U-shaped section 12, on either side thereof.
- the wings 13, 15 are most conveniently formed integrally with the limb 18 of the part 10, and the U-shaped part 12 is formed by welding two plates 17, 19 to the front face of the limb 18.
- the reinforcing parts 24, 24a of Fig 1 may be integrally formed with the plates 13, 15.
- the outboard end of the limb 54 is downturned at 58 to form a lip and the distance between the vertically extending limb 60 and the lip 58 is such as to accommodate the thickness of the building block 56.
- the block or blocks forming the next course of blocks 62 are cut away as at 64 to accommodate the upstanding reinforcing ribs, one of which is denoted by 66.
- Flooring timbers 68 are shown laid on the joist 52 and the underside of these timbers may need to be cut away also to accommodate the upstand 66.
- a ceiling sheet 69 is shown attached to the underside of the joist 52
- FIG. 70 Three nail or screw holes are shown at 70, 72 and 74 to allow the joist 50 to be secured to the side cheeks of the hanger, one side cheek of which is denoted by 76 in Fig 6.
- Fig 7 shows how a hanger such as 50 can be used to advantage in a situation where minimal masonry is permitted above the horizontal limb 54 due to the design of the building and in particular in this case the roof.
- one such hanger is denoted by 78 and is shown supporting one end of a horizontal member 80 of a roof truss generally designated 82, at a position where only a small triangular block section (typically constructed by cutting a conventional rectilinear block in manner known per se), can be accommodated above the hanger
