Description

Structural building elements

The present invention relates to a structural building element, and more particularly to a connector for joining an elongate member to a frame, such as a post wall and a frame member.

In the frame of the column wall, the horizontal channel is used to fix the ceiling and the floor, while the vertical column of the formed metal is placed in the channel and then fixed in place. Horizontal wooden brick walls of profiled metal can also be placed between the columns to increase the strength of the overall structure when needed. The sheet is then fixed to the frame structure and joined together to form a wall. This conventional frame theory has a number of disadvantages, including the need to use a variety of different forming metals and/or joining each horizontal channel, vertical column, and horizontal wood frame brick wall, while requiring further structure to construct a building frame that surrounds the entrance and exit. And provide a fixing point for the electrical box such as a power socket; in order to construct the frame structure, the frame member requires a relatively high degree of cutting precision, and then is tightened or otherwise fixed together. This is quite difficult and time consuming.

The international patent application PCT/EP2014/079322, which is hereby incorporated by reference, discloses a method of solving the problems by means of a connector which can be axially pushed into one end of a first channel-section frame member such that the connector The end portion protrudes axially from the frame member. The projection is provided with a laterally extending chute on at least one pair of opposite sides thereof. In use, the protruding end is inserted into the open channel of the second frame member, which extends 90 degrees or is inclined to the first frame member. The first frame member is then rotated about its longitudinal axis such that the chute receives a respective inwardly directed lip on the passage opening of the second frame member. In this way, no screws or other fixing means are required. Any incompatibility in the length of the first frame member can be counteracted by axial movement of the connector relative to the first frame member. In this way, only a low degree of cutting accuracy is required.

Frame members of the aforementioned type are typically made of a thin metal that is not strong enough to support the door frame. When forming the opening of a door, current practice often involves the use of double thickness metal and sometimes wood inserts. Therefore, more components are needed, including more steps in the measurement, cutting, folding, assembly and fixing of the components.

According to a first aspect of the present invention, there has been provided a connector for joining first and second elongate frame members, at least a first member comprising a hollow extending axially along the member, at least a second member having a second member having a rib-like longitudinally extending forming surface, the connector comprising: a first elongated end portion adapted to be slidably received at one end of the first frame member; and a second end portion having a distal end surface located perpendicular to a longitudinal axis of the first end portion and the distal end surface including a contour complementary to a contoured surface of the second frame member; and a fastening device for fastening the distal end surface Abutting against the forming surface of the second frame member.

In use, the door frame can be constructed by inserting the first end of the connector into one end of the first frame member, and then the second end of the connector is positioned against the molding surface of the second frame member, thus connecting The distal end of the piece abuts upwardly and enters a state of complementary engagement with the forming surface of the second frame member. The tolerance of any of the first frame members over the length may be offset by displacement of the connector in the axial direction relative to the first frame member. The end face of the connector then abuts against the contoured surface of the second member to form an L-shaped structure to form the sides of the desired frame.

The manner in which the shaped distal end of the connector is combined with the contoured surface of the second frame member ensures precise positioning of the two frame members such that the connector is nearly incapable of rotation or misalignment, providing a combination of frames without protruding metal overlap or fixation elements The advantages of the front and rear end faces of the tablet.

The second frame member can be vertically fixed and formed of a thicker metal than the frame member of the passage section conventionally used, and can be strengthened to withstand the weight of the door panel without any additional reinforcement; the entire door frame can be By using a frame member having the connector of the present invention at each corner, however, conventional frame members (without a forming surface) can also be used for one or more sides of the frame.

The second connector may be inserted at the opposite end of the first frame member such that the first frame member may be secured between the two frame members; the risk is that when one connector is inserted at one end of the first frame member, the connector may It will slide into the hollow when another connector is fixed into the other end. In this case, the connector needs to be pushed back before connecting the two components. Accordingly, the connector may include a pair of stops to prevent the first end of the connector from being pushed excessively into the frame member, the stop being resiliently deformable to allow the connector to enter the first frame member as intended, and It is frictionally bonded to the inner surface of the first frame member to prevent it from sliding completely.

The embodiments of the present invention are merely illustrative of the following figures, which are:

Referring to Figure 1 of the drawings, the connector 1 is incorporated into the channel 3 of the vertically disposed C-shaped elongated frame member 2. To achieve this, the outer dimension of the cross section of the connector 1 is roughly matched to the interior of the channel 3. Dimensions, the component D shown in Fig. 1 indicates the conventional reference numerals of the various dimensions of the connector 1; the longest dimension of the connector 1 extends vertically in Fig. 1 and is indicated as the length L, and the remaining dimensions are related to the connector A cross section of 1 comprising a shortest (narrow) cross-sectional dimension W1 and a longest (wide) cross-sectional dimension W2. The end of the connecting member 1 is coupled to the passage 3, the end of which is the first end portion 20, and the passage 3 of the C-shaped elongated frame member 2 is the end of the end of the C-shaped elongated frame member 2 (the end to which the connecting member 1 is connected in Fig. 1) Extend to the other end. The manner of bonding may be a relatively loose sliding combination that allows the connector 1 to move axially relative to the C-shaped channel 3 for reasons described later (so that the connector 1 can slide relatively or slide out of the channel 3 of the member 2) Or it can also be a combination of relatively tight fits. The C-shaped frame member 2 includes an opening 4 into the passage 3 which extends along one side (side) of the C-shaped member 2, and the side of the C-shaped member 2 having the opening also includes a longitudinal lip (flange) 5a, 5b, which extend along the opening 4, thereby retaining the connector 1 in the channel 3.

Above the first figure, the horizontally disposed C-shaped frame member 6 has a longitudinally traversing passage 7 having an opening 8 into the passage 7 which extends along one side (side) of the C-shaped member 6, C-shaped The side of the member 6 having the opening also contains longitudinal lips (flanges) 9a, 9b which extend along the opening 8. It can be seen from Fig. 1 that the frame members 2, 6 preferably have the same profile and have the same profile (cross section). When the connector 1 is used, the connector can combine two elongated members having the same profile (section). .

The end portion of the connector 1 remote from the first end portion 20 is designated as a second end portion 21, and the second end portion 21 is provided at a predetermined distance from the end of the (closest) connector 1 to provide a predetermined distance. A groove 10 extending laterally around the four sides of the connector 1.

The second end portion 21 of the connector 1 is thereby bonded to the frame member 6. To achieve this, the connector 1 is positioned at an ideal distance along the length of the frame member 6 at the opening 8 of the channel 7; the connector 1 is relatively The frame member 6 and the first rotational position of the passage 7 are provided upward (direction arrow A) to the passage 7, and the first rotational position is the widest side (dimension W2) of the joint 1 parallel to the edge of the opening 8, or The narrowest side (dimension W1) of the joint 1 between the edges of the opening 8 is spanned. In this orientation, the connector 1 can be inserted through the opening 8 into the channel 7 of the member 6, as can be seen in Figure 1 that the connector 1 is not in the first rotational position, once lifted up to the channel 7, the connection The piece 1 will rotate clockwise (direction arrow B) to bring the groove 10 close to the lips 9a, 9b; when the connecting member 1 rotates, the lips 9a, 9b will enter the groove 10, and then continue to rotate to 90 The degree until the shortest edge (dimension W1) is parallel to the edge of the channel 8, which is the second rotational position of the connector 1 relative to the member 6, as can be seen in Figure 1 that the connector 1 is in the second rotational position. In the second rotational position, the maximum cross-sectional dimension W2 of the connecting member 1 extends across the opening 8 and is substantially filled in the width of the channel 7, and the connecting members 1 are angled along the two square edges of the length, the connecting member The beveled edge 12 of 1 makes it easier to rotate within the channel 7; without this beveled edge, the maximum cross-sectional dimension W2 of the connector 1 needs to be reduced so that the connector 1 can be rotated from the first rotational position to the first Two turning positions. In other words, when at least two edges adopt beveled edges, the maximum cross-sectional dimension W2 of the connector 1 will be closer to the width of the channel 7, so that the lips 9a, 9b will have more areas to accommodate. Within the groove 10, a stronger bonding force of the connector 1 and the member 6 is provided. The insertion fixing mechanism is based on the friction between the thin groove 10 and the edge contour of the metal segment, and therefore, the four edges are inclined because the contact area of the groove 10 with the lips 9a, 9b is lowered instead of An ideal design.

When the connector 1 is joined to the member 6 by the second end portion 21, the sliding engagement of the second end portion 20 of the connector 1 allows the member 2 to be up or relative to the connector 1 (which itself is fixed to the member 6) Sliding down (direction arrow C), it is understood that the connector 1 can be used for vertical uprights to be secured to the ceiling and (horizontal) floor channels. The sliding combination will absorb the top deflection of the ceiling channel relative to the floor channel with the deformation of the mounting post; in addition, because the length can be adjusted by the connector 1, the sliding combination can reduce the length of the member 2 requiring precise cutting; Further, since a portion of the distance is spanned by the connector itself, the member 2 will be shorter than the conventional length.

It can be understood that the above sliding combination can also be replaced by a horizontal member, and the torsion combination can replace the vertical member; on the other hand, when used to form a ceiling or a floor structure, both members can be horizontal; When the frame of the roof is inclined, one or both of the members may have an oblique angle. However, in these examples, it can be understood that the connection between the two members is a right angle connection; however, in theory, when the first end portion (sliding fixed) and the second end portion (torsion fixed) are not simply straight lines The present invention can also be used in the case of a non-orthogonal connection when the structure is a curved surface or an angled structure.

The connector 1 described herein is identical to the connector disclosed in the international patent application PCT/EP2014/079322, the entire disclosure of which is incorporated herein by reference. The wall also forms a relatively thin piece of metal.

Referring to Figures 2-6 of the drawings in accordance with the present invention, the present invention further includes a second type of C-shaped frame member 23 having an axially extending passage 24 through which the frame member 23 is formed from sheet metal. And slightly thicker than the metal sheet used in the frame members 2, 6 disclosed in FIG. 1; it includes an opening 25 extending along one side (side) of the C-shaped member 23 into the passage 24, the C-shaped member This side having the opening 25 also includes lips 26a, 26b extending along one side of the opening 25 and formed by a double folded thickness of metal.

The frame member 23 further includes a pair of axially extending passages 27 on the outwardly facing bottom wall, the passages 27 and the folded lips 26a, 26b providing additional dimensions relative to the members 2, 6 disclosed in FIG. strength. The frame member 23 made of the above-mentioned thicker metal sheet will be more suitable for forming a frame around the opening in the door, and the internal dimensions of the passage 24 are roughly the same as those of the members 2 and 6 in Fig. 1, so that the connecting member 1 can be bonded to the channel 24 in the same manner as described in the aforementioned first figure.

For example, when forming a frame around the door, the frame member 23 is vertically fixed to the side of the opening, by which the side is suspended from the door, and the frame member 23 is made of a wooden brick wall or a cross member. Support (not shown) is attached and attached to the channel 24 using the connector 1 and attached in the same manner as described in FIG. Since the frame member 23 does not provide a passage toward the opening in the door, the horizontal top frame member (or the top) cannot be attached, and the connector 1 is used in the same manner as described in Fig. 1.

The second end 21 of the connecting member 1 has a distal end surface which is disposed perpendicular to the long axis of the first end portion 20 and includes a pair of ribs 22 extending in the W1 direction in FIG. 1 and having a rib cross section The distal end face of the contour is contoured and matched to the outer surface of the frame member 23 of the cross-sectional channel profile. In use, the connector 1 slides into the end of the horizontal top frame member 28 in the same manner as the connection member 2 of Fig. 1; the top frame member 28 is identical to the frame members 2, 6 of the prior art in Fig. 1, or It may also comprise components of the frame member 23 of the present invention. The second end 21 of the connector 1 is then positioned against the contoured surface of the frame member 23 such that the ribbed distal end of the connector 1 abuts upwardly and into a state of complementary engagement with the channel profile of the frame member 23. The tolerance of any of the top frame members 28 in length may be offset by the displacement of the connector 1 in the axial direction relative to the top frame member 28. The end face of the connecting member 1 is fixed by the screw 30 through the opening 31 formed in the end wall of the connecting member 1 by the opening 32 of the bottom surface of the connecting member 1, and abuts against the passage surface of the frame member 23. . In this way, a strong L-shaped structure can be provided to form both sides of the desired door frame; the groove 29 can extend longitudinally along the center of the passage surface outside the frame member 23, thereby lifting the position of the screw 30 Tips and prevent slippage during insertion.

The manner in which the ribbed distal end of the connector member 1 is combined with the channel surface of the frame member 23 ensures precise positioning of the two frame members 23, 28 such that the connector member 1 is nearly incapable of rotation or misalignment, providing no protruding metal overlap or The advantages of the front and rear end faces of the flat frame of the fixing element.

The connector 1 includes a pair of stops 33 for avoiding excessive pushing of the first end of the connector 1 into the frame member 28, the stop 33 being resiliently deformable to allow the connector 1 to enter the frame member 28 as intended, And it is frictionally bonded to the inner surface of the frame member 28 to prevent it from sliding completely.

The connector 1 can be single-molded from a plastic material and includes an open front wall and ribs 34 extending between the side walls 35. The ribs 34 extend laterally of the connector 1 and define one or more spaces 36. , to the power outlet fixed.

The first end portion 20 of the connecting member 1 includes a distal end surface 37 which is inclined to the long axis of the first end portion 21 and includes a groove 38 extending on the opposite side and extending laterally; the groove 38 and the The groove 10 of the two end portions 21 has the same function, please refer to FIG. 4D, thereby providing a joint structure for connecting the channel type frame member, which makes the second end portion of the connector 1 at an oblique angle of 32 to 50 degrees. The part 21 is inserted into the frame member. The first end portion 20 of the connector 1 is then secured in its original position by a screw through an elongated opening 39 formed in the distal end face 37.

Referring to FIGS. 7A-7C, the connector 1 includes a weak transverse line 40 adjacent to the first and second ends 20, 21, which is a thinner material of the connector 1 along the line in different regions. Formed on the side wall, the end of the horizontal line extends to the edge of the connector without reducing its thickness to avoid inadvertent damage of the connector 1. In use, the user can cut the tool to simply cut the edge (e.g., 41) so that the connector 1 spans both sides, thus enabling the connector 1 to be truncated, such as when the connector 1 is inserted into a shorter length frame member.

If desired, the connector can be adjusted to securely secure the ends of the frame member relative to each other, such as by turning a screw through the associated frame member into the connector, and the frame member can include a groove to aid the screw. Positioning.

The connector disclosed in accordance with the present invention is simple and inexpensive in construction, and enables a wide variety of frame members to be easily and securely attached and secured together using a single connector.
