Description

DECK ATTACHMENT BRACKETS
AND BUILDING USING SAME
FIELD
[0001] The improvements generally relate to attachment of a deck to a concrete foundation of a building and more specifically relate to deck attachment brackets which avoid contact with sidings of the building.
BACKGROUND
[0002] A building such as a house typically has a concrete foundation protruding from the ground, and a structure fixedly disposed on the concrete foundation. In some climates, especially in northern climates, the structure generally includes insulated walls externally covered by sidings for protecting the building from weather hazards. In some instances, an outdoor floor made of wood or woodlike materials (referred to herein as "deck") is attached to the building to provide additional surface to the building, especially for use in fair weather.
Such attachment is generally done using deck attachment brackets. Although existing deck attachment brackets were satisfactory to a certain degree, there remains room for improvement.
SUMMARY
[0003] A need occurred in providing a deck attachment bracket which can avoid altering the siding of the structure which can, in turn, avoid insulation issues.
Another need occurred in providing a deck attachment bracket which can rigidly attach the deck to the building.
Another need occurred in providing a deck attachment bracket which can facilitate the process of attaching the deck to the building using a plurality of identical deck attachment brackets.
[0004] In accordance with one aspect, there is provided a deck attachment bracket comprising: a first metal strip having a first portion leading to a first fold, a second portion extending from the first fold to a second fold, and a third portion extending from the second fold, the first portion having at least one bore, the first and third portions being parallel to one another and extending in opposite directions relative to the second portion; a second metal strip being welded to the second portion, in a position extending parallel and adjacent to the third portion, and being spaced from the third portion by a joist receiving spacing, and at least one joist fastener aperture extending across both the third portion of the first metal strip and the second metal strip; and a metal web structurally connecting at least the second portion of the first metal strip and the first portion of the first metal strip.
[0005] Another need occurred in providing a deck attachment bracket which prevents vibration of the deck during use thereof.
[0006] In accordance with another aspect, there is provided a deck attachment bracket for attaching a deck to a concrete foundation of a building, the deck attachment bracket comprising: an attachment portion being attachable to the concrete foundation of the building for use; a siding clearing portion being made integral to the attachment portion and extending perpendicularly from the attachment portion; a joist receiving member being made integral to the siding clearing portion, the joist receiving member having two spaced-apart members configured to receive a joist from above and being spaced from the concrete foundation by a siding clearing distance during use; and a reinforcing web made integral to and extending perpendicularly from the attachment portion, along and under the siding clearing portion, and upwardly along an external face of the joist receiving member during use.
[0007] In accordance with another aspect, there is provided a building having a deck attached using a plurality of deck attachment brackets as presented herein.
[0008] Many further features and combinations thereof concerning the present improvements will appear to those skilled in the art following a reading of the instant disclosure.

DETAILED DESCRIPTION
[0013] Fig. 1 shows an example of a deck attachment bracket 100 attaching a deck 10 to a building 20. For ease of reading, the deck attachment bracket 100 is shown in an exemplary environment where it can be used. For instance, the building 20 is shown to have a concrete foundation 30 and a structure 40 fixedly disposed on the concrete foundation 30.
As depicted, the structure 40 has a wall 50 which is externally covered by a siding 60.
[0014] Broadly described, the deck attachment bracket 100 has an attachment portion 102 which is attachable to the concrete foundation 30, a siding clearing portion 104, a joist receiving member 106 for receiving at least a joist 70 of the deck 10 and a reinforcing web 108.
[0015] The siding clearing portion 104 extends from the attachment portion 102 for providing at least a siding clearing distance L sufficient to clear the siding 60 during use of the deck attachment bracket 100. In other words, the siding clearing portion 104 extends from the attachment portion 102 in a direction away from the concrete foundation 30 when the deck attachment bracket 100 is attached to the building 20.
[0016] The joist receiving member 106 is made integral to the siding clearing portion 104 and is spaced from the siding clearing distance L from the attachment portion 104 to leave room for the siding 60 of the building 20. More specifically, the joist receiving member has two spaced-apart members configured to receive the joist(s) 70 from above during use. The joist receiving member 106 is configured to receive and maintain into position the joist(s) 70 of the deck 10 during use of the deck attachment bracket 100.
[0017] The reinforcing web 108 is made integral to and extends perpendicularly from the attachment portion 102, along and under the siding clearing portion 104, and upwardly along an external face of the joist receiving member 106 during use, which can provide satisfactory structure to the deck attachment bracket 100.
[0018] The attachment portion 102, the siding clearing portion 104, the joist receiving member 106 and the reinforcing web 108 are each made of a structural material such as metal or molded plastic. The attachment portion 102, the siding clearing portion 104, the joist receiving member 106 and the reinforcing web 108 are made integral to one another in a manner sufficient to provide satisfactory strength to the deck during use.
[0019] For ease of understanding, the following paragraphs present one possible embodiment of the deck attachment bracket 100 which has been found satisfactory.
However, in alternate embodiments, it is understood that the attachment portion 102, the siding clearing portion 104, the joist receiving member 106 and the reinforcing web 108 can be provided in other forms. For instance, the reinforcing web 108 can be flat.
[0020] Referring to Figs. 1 and 2, the deck attachment bracket 100 has a first metal strip 110 having a first portion 110a leading to a first fold Fl, a second portion 110b extending from the first fold Fl to a second fold F2, and a third portion 110c extending from the second fold F2. The first metal strip 110 has an external face 112 and an inward face 114. As it can be seen in Fig. 1, the first metal strip 110 has a Z-like shape when so folded. For ease of reference, it is noted that the external face 112 faces towards the deck 10 and the inward face 114 faces the concrete foundation 30 during use of the deck attachment bracket 100. As depicted, the first and third portions 110a and 110c are parallel to one another and the second portion 110b extends perpendicularly between the first and third portions 110a and 110c.
[0021] The deck attachment bracket 100 also has a second metal strip 116 which extends parallel and adjacent to the third portion 110c. The second metal strip 116 is typically perpendicular to the second portion 110b of the first metal strip 110. In this embodiment, the second metal strip 116 is welded to the inward face 114 of the second portion 110b at a given distance (such as the siding clearing distance L) from the fold Fl between the first and second portions 110a and 110b to provide a joist receiving spacing. Exemplary lengths of the siding clearing distance L and of the joist receiving aperture can each be of about 7 cm.
The deck attachment bracket 100 has at least one joist fastener aperture extending across both the third portion 110c of the first metal strip 110 and the second metal strip 116. As depicted in Fig. 1, the joist receiving spacing snugly receives the joist(s) 70 during use.
[0022] As shown, the first and third portions 110a and 110c of the first metal strip 110 and the second metal strip 116 each has at least one bore 118. The bore(s) 118 of the first portion 110a of the first metal strip 110 are generally used for attaching the attachment portion 110 directly to the concrete foundation 30 using fastener(s) such as concrete screw(s) 120. An example of such a concrete screw 120 is the Hilti KWIK HUS.
In the embodiment shown, the bore(s) 118 of the third portion 110c of the first metal strip 110 and of the second metal strip 116 are generally used for clamping the joist(s) 70 of the deck 10 using a nut and bolt connection 122 during use. Also shown, the other bore 118 of the third portion 110c of the first metal strip 110 can be used to attach the deck attachment bracket 100 to the joist(s) 70 of the deck 10 using a fastener such as a wood screw 124.
[0023] As mentioned above, the reinforcing web 108 is provided in the form of a flat metal web 126 which structurally connects the second portion 110b of the first metal strip 110 and the first portion 110a of the first metal strip 110. The flat metal web 126 has a fixed end welded to the external face 112 of the second and third portions 110a and 110b of the first metal strip 110 and an opposing free end. Optionally, the flat metal web 126 is made integral to the third portion 110c of the first metal strip 110, such as shown in Figs.
1-3. As better seen in Fig. 2, the flat metal web 126 is welded to the external face 112 of the first, second and third portions 100a, 110b and 110c of the first metal strip 110 to provide satisfactory strength to the deck attachment bracket 100. In the embodiment shown, the flat metal web 126 can be positioned between one of the longitudinal edges 128a and 128b of the first metal strip 110 and the bores 118 along the external face 112, which was found convenient.
In this embodiment, the flat metal web 126 has a perimeter which snugly corresponds to the profile of the external face 112 of the deck attachment bracket 100. In an embodiment, the configuration of the fixed and free edges is designed such as to provide satisfactory structure to the deck attachment bracket 100 while requiring a minimum amount of material to save costs.
[0024] In an embodiment where metal is used, the attachment portion 102, the siding clearing portion 104, the joist receiving member 106 and the reinforcing web 108 can be made integral to one another via one or more welding joints. In such an embodiment, metal such as steel (e.g. in compliance with the standard CAN/CSA G40.21 300W) has been found satisfactory. For instance, the first metal strip 110 and the second metal strip 116 can be made from an extruded steel flat strip having a cross section of 76 mm per 5 mm. It is also noted that the strength of the welding joint can provide satisfactory structure to the deck attachment bracket 100. A welding joint in compliance with the standard CAN/CSA ASTM
A123 has been found satisfactory. However, any type of joint can be used.
[0025] Three (3) deck attachment brackets 100 are shown in Fig. 3 during use.
More than two or three deck attachment brackets can also be used. More specifically, the three deck attachment brackets 100 collectively receive the joists 70 and are attached to the concrete foundation 30. The deck attachment brackets 100 shown are suitably distributed along a width of the concrete foundation 30 for distributing the load applied by the deck 10 evenly along the concrete foundation 30. It was found that decks attached to the building using existing deck attachment brackets can lack rigidity (e.g. due to their plurality of assembled parts) which caused the deck to vibrate. Such vibration of the deck was found inconvenient for users. Accordingly, the deck attachment bracket 100 includes the flat metal web 126 which is perpendicular to the first metal strip 110 and which is made integral to the external face 112 of the first metal strip 110. The flat metal web 126 provides satisfactory rigidity to the deck such that vibrations are deemed acceptable (e.g. at least partially perceptible). The deck attachment bracket 100 can thus be referred to as "anti-vibration".
[0026] A method of making the deck attachment bracket 100 is also provided.
The method includes a step of folding the first metal strip 110 in a first direction to form the first fold Fl. The method includes a step of folding the first metal strip 110 in a different direction to form the second fold F2, opposite the first fold Fl. The method includes a step of welding the second metal strip 116 to the second portion 110b of the first metal strip 110, between the first and second folds Fl and F2 such that the second metal strip 116 extends parallel to and adjacent the third portion 110c of the first metal strip 110. Optionally, the method can include a step of welding the flat metal web 126 along the first metal strip 110. The method can also have a step of drilling a plurality of bores in the first and third portions 110a and 110c of the first metal strip 110. More specifically, the step of drilling can include drilling a bore in the third portion 110c and drilling another bore in the second metal strip 116, where these bores are aligned to one another to receive the nut and bolt connection 122. The step of drilling can also include drilling another bore in the third portion 110c for receiving the wood screw 124. The step of drilling can also include drilling at least two bores in the first portion 110a of the first metal strip 110 for receiving the concrete screws 120.
[0027] As can be understood, the examples described above and illustrated are intended to be exemplary only. For instance, the first portion of the first metal strip can form a non-zero angle relative to the third portion of the first metal strip. It is understood that the folds of the first metal strip can form a non-perpendicular angle relative to the second portion thereof in another embodiment. In another embodiment, the second metal strip can form a non-perpendicular angle relative to the second portion of the first metal strip. The deck attachment bracket can be used for attaching a deck on any type of foundation.
The dimensions and/or proportions of the deck attachment bracket can vary depending on the load of the deck to support. For instance, the third portion of the first metal strip can be twice as long as the first portion of the first metal strip. The second portion of the first metal strip and the third portion of the first metal strip can have a similar length. The first portion of the first metal strip and the second metal strip can have a similar length. In an embodiment, the first portion of the first metal strip has a length of at least 30 cm, the second portion of the first metal strip has a length of at least 15 cm, the third portion of the first metal strip has a length of at least 15 cm, and the second metal strip has a length of at least 15 cm. For instance, the metal web can protrudes forwardly of at least 4 cm from the third portion of the first metal strip. As mentioned, the deck attachment bracket can have any satisfactory dimensions and/or proportions. The scope is indicated by the appended claims.
