Description

Multi bracket for non-welding square pipe connection {THE MULTY BRACKET CONNETING THE SQUARE PIPE}

In the present invention, horizontal beams and vertical columns can be interconnected by non-welding in a formal and traditional building, as well as horizontal beams and vertical columns in a non-standard, non-geometrical and deformed building by non-welding. It is a technical field related to multi brackets that can be connected.

In modern times, architecture and interior design have moved away from the existing geometric shapes and the concept of atypical or non-linear has become more prominent. An architectural method that uses free curves to develop unpredictable and atypical spaces is emerging.

This atypical type of building includes both cases where a straight line is inherent in the cross section or not, and after constructing a truss by connecting vertical columns and horizontal beams to form a curved surface, exterior finishing materials and insulation materials are applied to the surface. . At this time, the truss is completed by interconnecting a plurality of square tubes disposed in mutually orthogonal, parallel, curvature, etc. directions.

In relation to the method of interconnecting the square tubes, there are a method of welding the connecting part of the square tubes and a method of fastening (connecting) using brackets, bolts, and nuts.

Among them, the method of connecting each tube by welding depends on the process time, cost, and completeness of construction, etc., depending on the skill of the welder, especially in the case of atypical buildings. An additional process is required, such as polishing the generated beads or cutting out one side of the finishing material to increase adhesion with the surface of the frame. Furthermore, when a welding defect occurs, the bead falls, cracks occur, or the smoothness of each tube is lowered, affecting the rigidity of each tube, and there is a high risk of safety accidents such as fire risk due to welding sparks. There is a problem.

In addition to the welding method, as a non-welding method, a method of connecting each tube using brackets and brackets is disclosed in Korean Patent Registration No. 10-2113954, Utility Model Registration No. 20-0480783, and Registered Design No. 30-0463787. has been

Document 1 is a configuration in which a fitting member is placed at the bottom and coupled with a coupling member at the top when connecting square pipes vertically and horizontally, and Document 2 is a square pipe connector by inserting a square pipe into an opening surface to connect the pipe and the pipe. It is a structure that fastens the bracket. In the case of the above documents 1 and 2, it is applied to a standard type of building, and is limited only to interconnecting vertical columns and horizontal beams orthogonally and in parallel. Therefore, in order to develop an atypical building, a welding process is indispensable, and it is vulnerable to the load of vertically and horizontally connected frames, or it is not easy to construct a finishing material covering the frame because the coupling member protrudes from the square pipe, or the pipe and bracket are connected. There is a problem in that the process efficiency is significantly reduced as a connection member must be separately added to the area to be.

In other words, the square pipes constituting the truss are interconnected, making it impossible to express the curved surface of the exterior of the building, and distorted circles due to inefficiency of finishing materials, arcs whose center cannot be recognized, curves with various curvatures, Non-parallel lines cannot be expressed three-dimensionally through the exterior form and interior space of the building, and it is costly to combine the pipes that make up the truss, and it is difficult to process the finishing materials. Therefore, there is a need for a new method that does not involve a welding process and can solve the above problems.

One object of the present invention is to be able to combine vertical columns and horizontal beams at free angles by non-welding so that free expression of modern atypical buildings can be developed, and horizontal beams and vertical columns can be inserted by inserting square tubes into brackets without using a welding process. By interconnecting them, not only simplify the work but also promote the accuracy and convenience of the work.

A c-shaped bracket according to one aspect of the present invention to solve the above problems;

The bracket 1 includes a fixing surface 10 having one surface fixed to the vertical pillar D1; And upper and lower surfaces 20 extending from both ends of the fixing surface 10; Including, the fixing surface 10, a display unit 100 for guiding the reference position of the installation point of the exterior finishing material and the fastening position of the bracket on one side; A first through hole 40 disposed at a predetermined distance so as to be coupled to the vertical pillar D1 by a fastening member; and a support portion 400 extending from the fixing surface 10 and bending on the other side; Including, the fixed surface and the upper and lower surfaces are connected by a guide unit 200 for guiding and controlling the position where the horizontal beam D2 is inserted and disposed, and the upper and lower surfaces 20 are disposed at a predetermined distance through the second through ball 41; It is characterized in that it includes.

The upper and lower surfaces 20 have a structure that surrounds the cross section of the horizontal beam D2 so that the horizontal beam D2 can be connected to the vertical column D1 at a predetermined angle, and the guide part 200 is connected to the path through which the horizontal beam is inserted. It is characterized by an end shape capable of guiding and controlling the fixed position.

In the method of forming a support truss using a non-welding multi-bracket according to another embodiment of the present invention, one surface of the fixing surface 10 is disposed on one surface of the vertical column D1, and the fastening member is connected through the first through hole 40. Step 1 of fastening the vertical pillar (D1) and the fixing surface (10);

Insert the horizontal beam (D2) into the insertion part 500 to adjust the angle to achieve a predetermined angle with the vertical column (D1), match the end of one side of the coupling matching surface 50 and the horizontal beam (D2) or support ( Step 2 of contacting one surface of the horizontal beam (D2) with 400) and then fastening the horizontal beam (D2) and the upper and lower surfaces (20) with a fastening member through the second through hole (41); a third step of arranging a metal panel on the outer surface of the support truss formed in the first and second steps on the same line as the display unit 100; and 4 steps of constructing finishing materials; It is characterized in that it includes.

The multi-bracket for connecting square tubes without welding according to an embodiment of the present invention has the effect of three-dimensionally expressing the curved surfaces of an atypical building by connecting vertical columns and horizontal beams at various angles.

Furthermore, vertical columns and horizontal beams can be connected without a welding process even in the case of additional deformation of a formal building, which not only blocks the risk of fire, but also reduces the difference in completion due to the skill of the welder, saves construction time and costs, and forms a stable and solid bond. can do.

In addition, by minimizing the interference surface between the finishing material and the square tube in the step of processing the finishing material after the formation of the frame, not only the construction of the finishing material can be facilitated, but also the contact surface between the finishing material and the square tube can be firmly adhered.

In particular, by placing the display unit 100 on one side of the fixing surface, it is easy to see the reference position of the installation point of the external finishing material installed on the bracket truss and the fastening position between the brackets. In addition, the guide part 200 can be placed to control and guide the position where the horizontal beam is inserted into the bracket, and after fixing the vertical column and the bracket with a screw, interference with the horizontal beam inserted can be minimized.

In addition, as a structure in which a part of the plate is folded, a bracket by a non-welding manufacturing method is used for connecting the non-welding square pipe, and thus, there is an advantage in that it is easy to manufacture brackets of various shapes.

Hereinafter, a bracket for connecting a non-welded square pipe according to an embodiment of the present invention will be described with reference to the drawings.

Recently, a specific building has been designated as a trademark symbolizing a region or place, and in particular, atypical structures including curvature such as oblique shapes, curved shapes, unidirectional curved shapes, and double bending curved shapes that combine with straight lines rather than straight or parallel sections. Buildings are harmonizing with the existing surroundings or creating new spaces.

These atypical buildings are macroscopically progressed through temporary construction, earthwork, frame work, and interior and exterior finishing work. In particular, the framing work is a basic construction that determines the shape of a building, and various framing materials such as wood and steel are used. For example, in the case of using square pipe-type square tubes as a frame, the square tubes are set apart as vertical columns (D1), and the vertical columns (D1) are interconnected with horizontal beams (D2) to complete the support truss. The connection of is common to connect the vertical column (D1) and the horizontal beam (D2) by welding. However, the welding truss construction method has the disadvantages that the fire risk has recently been highlighted, the construction time is long, and the completion of construction is not uniform depending on the skill of the welder.

In particular, in the case of atypical buildings, it is necessary to connect the horizontal beam (D2) at a predetermined angle to the vertical column (D1), which requires additional time and cost, such as positioning and processing of square pipes, compared to the welding process that implements general straight and parallel lines. It takes

The present invention shows a multi-bracket capable of connecting square tubes at various angles in a non-welded manner in FIGS.

Specifically, the present invention fixes the bracket for connecting the c-shaped square tube to the vertical column (D1), and then inserts and fixes the horizontal beam (D2) to the insertion portion 500 to mutually connect the vertical column (D1) and the horizontal beam (D2). connect

A multi-bracket for connecting square tubes without welding according to an embodiment of the present invention includes a fixing surface 10 and an upper and lower surface 20 as shown in FIGS. 1 and 2.

Specifically, the c-shaped bracket is composed of upper and lower surfaces 20 into which the horizontal beam D2 is inserted and fixed based on the fixing surface 10 in contact with some of the side surfaces of the vertical pillar D1, as shown in FIGS. 3 and 4, but one A portion of the plate is bent to form the fixing surface 10 and the upper and lower surfaces 20.

At this time, one side of the fixing surface 10 includes a display unit 100 disposed on the same line as the edge of the vertical pillar D1 and guiding the fastening position between the plurality of brackets and the reference position for installing the exterior finishing material.

In the case of fixing the fixing surface 10 to the side surface of the vertical pillar (D1), the position of the groove and the marker marked on the side surface of the vertical pillar (D1) are matched to accurately fix the fixing surface 10 to the vertical pillar (D1). can be combined In addition, after fixing the plurality of vertical columns (D1) to the ground, in the process of connecting the vertical columns (D1) and the horizontal beams (D2) by brackets, the brackets are matched with the markers displayed on the vertical columns (D1) to match the positions of the grooves It is coupled to each vertical pillar (D1). Then, by inserting the horizontal beam D2 into the bracket, the positions of both ends of the horizontal beam D2 coupled to the plurality of vertical pillars D1 can be arranged on the same line. Therefore, it is possible to easily and conveniently connect the vertical columns (D1) and the horizontal beams (D2), and to secure the horizontality of both ends of the horizontal beams (D2) on the same line of the plurality of vertical columns (D1).

In addition, after constructing the support truss by connecting the vertical column (D1) and the horizontal beam (D2) with brackets, in the process of combining the panels covering the surface of the support truss, the operator can easily recognize the position where the panel is placed by the groove By disposing the exterior finishing material on the display unit 100 located at the center of one surface of the fixing surface 10, the convenience, precision, and robustness of exterior finishing material construction can be significantly improved, and process efficiency can be improved. Furthermore, there is an advantage in that the accuracy of the entire process can be improved by not only being able to precisely place the panel at a desired location, but also being able to guide the mutual position of the materials used during the construction process.

The upper and lower surfaces 20 may have a fan shape, a segmented curved surface, or an oblique shape that can support the horizontal beams D2 disposed at various angles on the vertical pillar D1, and may have a shape similar to a fan shape.

The upper and lower surfaces 20 may include a coupling reference plane in which a constant radius point extending at an angle of 0 to 90 based on a specific point coincides with the distal end of the horizontal beam D2, and the angle is the vertical column D1 And can correspond to the angle formed by the horizontal beam (D2), it is possible to easily predict the coupling position of the horizontal beam (D2) coupled to the vertical column (D1) at various angles, the upper and lower surfaces (20) to the vertical column (D1) By forming a stable coupling with the end of the horizontal beam (D2) to be coupled, it is possible to achieve a stable coupling of the vertical column (D1) and the horizontal beam (D2). For example, when the vertical column (D1) and the horizontal beam (D2) are combined at an angle of 20, the radius point extended at an angle of 20 based on a specific point on the upper and lower surfaces (20) is one side of the corner of the horizontal beam (D2). It can be combined with the structure shown in FIG. In addition, when the vertical column (D1) and the horizontal beam (D2) are combined at an angle of 55, the radius point extended at an angle of 55 based on a specific point on the upper and lower surfaces (20) coincides with one side of the edge of the horizontal beam (D2) structure can be combined.

Alternatively, when the coupling angle is large as shown in FIG. 5 and the diameter of the cutting surface of the horizontal beam is relatively large compared to the width of the bracket, the horizontal beam can be stably supported by the bracket by contacting the horizontal beam to the support part. As shown in Figure 5, if the horizontal beam (D2) is sharply bent at an angle of 45 to the vertical pillar (D1), attach a rectangular vertical pillar or another vertical pillar to fasten the bracket and the vertical pillar with a fastening member can do.

In one embodiment of the present invention, the radius value extended from a specific point at an angle corresponding to the coupling angle of the vertical column (D1) and the horizontal beam (D2) is used as the coupling matching surface 50, but the vertical column and processing in the actual field Depending on the state of the horizontal beam, the position of the bracket disposed on the vertical column can be adjusted back and forth, and the horizontal beam can be stably supported by the coupling matching surface 50 and / or the support unit and coupled to the vertical column.

On one side of the fixing surface 10, the upper and lower surfaces 20 are extended and bent as they are along the distal end of the guide portion, while the upper and lower surfaces 20 on the other side of the fixing surface 10 protrude more than the distal end of the guide portion and are bent. 6, even when the horizontal beam D2 is coupled to the vertical pillar D1 at a predetermined angle, the upper and lower surfaces 20 can stably support the horizontal beam D2.

Meanwhile, the other side of the fixing surface 10 may include a support part 400 that extends from the fixing surface 10 and is bent. When the horizontal beam D2 is inserted into the bracket as shown in FIGS. 3 and 4, the support 400 may be located outside or inside the horizontal beam depending on the angle.

For example, when the horizontal beam (D2) is fastened to the vertical column (D1) at a 90 degree position, the support part 400 surrounds the horizontal beam (D2) or the support part 400 is inserted into the inner surface of the bracket to form a horizontal beam. It can be stably supported by brackets. Or, as shown in FIG. 4, when the horizontal beam D2 is fastened to the vertical pillar surface D1 at an angle of 20, the support 400 is inserted inside the horizontal beam to form a certain number of horizontal beams D2 and vertical pillar D1. angle can be stably supported. At this time, the fastening member for fastening the bracket to the vertical column (D1) is located at the end of the vertical column (D1), that is, the support part 400 is a horizontal beam according to the angle formed by the vertical column (D1) and the horizontal beam (D2). It wraps around the outside of (D2) or is inserted inside to serve to support the vertical pillar (D1) and the horizontal beam (D2) to be stably fastened and maintained.

Furthermore, the support part 400 is obtained by cutting and bending a portion of one plate, and has an effect of preventing distortion of each fixing surface 10 and the upper and lower surfaces 20 and improving structural rigidity.

The fixing surface 10 includes a first through hole to couple one surface of the vertical pillar D1 by a fastening member. At this time, it is preferable to configure the first through hole to match the outer diameter of the fastening member. For example, when the fixing surface 10 is placed on one surface of the vertical pillar D1 and then a screw having an inner diameter similar to the diameter of the first through hole is inserted to combine the vertical pillar D1 and the bracket, vibration, etc. can prevent shaking from external force.

Furthermore, since the position of the horizontal beam (D1) inserted into the bracket is different depending on the angle at which the horizontal beam (D2) is inserted into the bracket, it is possible to stably fix the horizontal beam (D2) inserted at various angles without cracking. In consideration of the edge distance of the horizontal beam and the fastening member, the first through-holes may be distributed in a dispersed manner so as to be able to do so.

Meanwhile, the fixing surface and the upper and lower surfaces may be connected by the guide part 200 . In detail, when the vertical pillar (D2) is inserted from the outer surface to the inner surface of the bracket toward the insertion portion 500, the vertical pillar (D2) can be inserted along the guide portion 200, so that the vertical pillar (D2) is inserted into the bracket. ) can guide and control the inserted path. In addition, interference with the head of the fastening member fastened to the vertical pillar D1 and the fixing surface 10 can be prevented by the guide unit 200 .

For example, after arranging the fixing surface 10 on the vertical pillar D1, the tool fastens the fixing surface 10 and the vertical pillar D1 with a screw (fastening member) through the insertion part 500. The head of the screw protrudes into the inside of the face 10. At this time, the protruding head and the end of the horizontal beam (D2) inserted toward the fixing surface 10 play a role in guiding the horizontal beam (D2) into which the protruding guide portion 200 is inserted to be placed in an appropriate position so that the end of the horizontal beam (D2) inserted toward the fixing surface 10 does not interfere. do.

In detail, the guide part 200 is partially or entirely disposed on the same line as the distal end of the horizontal beam inserted toward the fixing surface, and the horizontal beam D2 is inserted toward the fixing surface to determine the position where the distal end is fixed. A shape that can be guided and controlled is desirable.

Preferably, the guide part 200 may have an end shape capable of guiding and controlling a path into which the horizontal beam D2 is inserted and a fixed position. For example, it may be a stair shape, a slot shape or a protrusion shape as shown in FIGS. 1 and 2, and is commonly disposed on the same line as the most distal end of the horizontal beam to be inserted, and the head of the fastening member can accommodate the protruding height. Provide a separation space between the horizontal beam and the fixed surface to However, it is not limited to this, and if the end shape is located at a predetermined interval so that the most distal end of the horizontal beam does not interfere with the fastening member head of the inner side of the fixing surface, it is not greatly limited.

One side of the guide includes a second through hole 41 for accommodating a fastening member to connect the horizontal beam D2 and the upper and lower surfaces 20 of the bracket, as shown in FIG. After inserting the horizontal beam (D2) into the bracket, the fastening member is inserted into the second through hole (41) through the upper and lower surfaces (20) to fasten the horizontal beam (D2) and the bracket.

At this time, the second through hole is different from the position of the horizontal beam (D1) inserted into the bracket according to the angle at which the horizontal beam (D2) is inserted into the bracket, like the above-mentioned first through hole, the horizontal beam ( In order to stably fix D2) without cracking, the second through-holes may be distributed in a dispersed manner in consideration of the edge distance between the horizontal beam and the fastening member.

Furthermore, it is possible to block the problem that the frame constructed by welding fails to accept external forces such as vibration and break, and also to accommodate minute errors that occur during the construction process, thereby improving the completeness of construction and securing quality. do.

As described above, the bracket for connecting square tubes of the embodiment of the present invention is a structure capable of connecting and coupling vertical and horizontal square tubes by configuring one plate and a part of the plate as a coupling part. In other words, the bracket for connecting the square pipe used to form the frame by connecting the vertical and horizontal pipe tubes to each other by the non-welding method also uses the structure of the bracket itself, so no welding process is added and the bracket for connecting the square pipe is formed by non-welding. can do. This means using a non-welding manufacturing bracket for the non-welding support truss manufacturing process.

In particular, as shown in FIGS. 4 to 7, the angle of the horizontal beam (D2) connected to the vertical column (D1) can be variously changed and constructed with one multi-bracket, so that the truss of the atypical building can be freely implemented to improve the appearance of the atypical building. There is an advantage that can be expressed in various ways by the non-welding method.

Meanwhile, according to another embodiment of the present invention, a method for connecting the square tubes using the above-described multi-bracket for connecting the square tubes without welding will be described.

In this regard, building construction is completed by combining the square pipes vertically and horizontally to complete the support truss, and then installing finishing materials such as exterior materials. At this time, as a finishing material such as an exterior material, a plate-shaped plate of metal or non-metal material, a heat insulating finishing material for insulation, and the like are used.

The above-mentioned finishing material construction methods include the intermittent heat method used simultaneously with exterior work when attaching plate-shaped plates and stones, the internal heat insulation method of putting insulation inside the frame, that is, making walls with gypsum board, etc. Likewise, there is an external insulation method in which the frame is wrapped with an insulation material from the outside and finished on top of it. Among them, the external insulation method, which is a method of wrapping the outside of the frame with an insulation material and finishing on it, can directly block the absorption and conduction of cold air or heat from the outside, and is a highly efficient method among insulation methods.

In particular, the external insulation method is a construction method that wraps the outer surface of the frame with a finishing material. Mold growth can be minimized.

The cause of the above problem is as follows.

If the ┼-shaped, T-shaped, or oblique connection parts among the square pipe connections are connected by welding, the bead by welding will create a void between the outer surface of the square pipe and the finishing material. Similarly, even when the square tubes are connected using brackets, when the brackets are placed in the area where the outer surface of the square tubes and the finishing material are in contact, a gap is generated between the outer surface of the square tube and the finishing material in contact.

Accordingly, the present invention describes a method of forming a lower frame using the above-described non-welding bracket for connecting square tubes. Specifically, after marking the portion where the horizontal beam D2 is disposed on the vertical column D1, arranging the display unit 100, which is the groove of the bracket, at the marked place, and then using the first through hole 40 as a fastening member to the vertical column. Step 1 of fastening (D1) and the fixing surface 10, after inserting the horizontal beam (D2) into the insertion part 500, the upper and lower surfaces of the horizontal beam (D2) as a fastening member through the second through hole (41) 20), step 3 of placing a metal panel on the outer surface of the frame formed in step 1 and step 2 on the same line as the display unit 100, and step 4 of constructing a finishing material.

In particular, as shown in FIGS. 4 to 7, there is an advantage that only one bracket can be coupled while varying the angle of the horizontal beam (D2) disposed on the vertical column (D1).

In addition, by using the display unit 100 to guide the arrangement of a plurality of brackets and the reference position of the installation point of the exterior finishing material, convenience of work can be pursued and precision can be improved.

As described above, the multi-bracket for connecting the non-welded square pipe according to the present invention includes the display unit 100, the support unit 400, and the guide unit 200 to facilitate the vertical column D1 and the horizontal beam D2 and the bracket. can be combined Furthermore, since the multi-bracket for connecting non-welded square tubes of the present invention has a structure in which one plate is cut and bent, it not only blocks structural defects and fire hazards that may occur by welding in advance, but also uses its own structure to achieve a non-welding method. Brackets can be manufactured by That is, since a bracket for connecting a non-welded square pipe is used to manufacture a non-welded lower frame, a separate welding process for manufacturing the bracket is not required, which has the effect of improving process efficiency.

In addition, since the lower frame is formed by the non-welding method, it has the advantage of easy disassembly and re-construction by releasing the piece.

On the other hand, the protection scope of the present invention is not limited to the description and expression of the embodiments explicitly described above. In addition, it is added once again that the scope of protection of the present invention cannot be limited due to obvious changes or substitutions in the technical field to which the present invention belongs.
