Description

Technology Field

[0001] The present invention relates to a system support with easy height adjustment of a horizontal member, wherein a flange member is vertically movably coupled to a vertical member to join a horizontal member to the side of a mutually spaced vertical member, and a connector coupled to the flange member by a fixing pin is provided at both ends of the horizontal member, thereby ensuring constructability and safety of the system support while freely adjusting the installation height of the horizontal member. Background Technology

[0003] In order to construct concrete structures such as slabs or beams at a construction site, formwork must be installed, and temporary supports must be installed to support the formwork and transfer the construction load downwards until the concrete reaches a predetermined strength.

[0004] In cases where it is difficult or unsafe to install general steel pipe supports, such as when the floor height is 4.2m or more, or when the thickness is thick and the casting load is large, like with transfer members, a system support is used to ensure constructability and safety (Registered Patent No. 10-1276738).

[0005] System supports are completed by assembling factory-manufactured, standardized, and modular components on-site, offering the advantage of easy installation and dismantling. Furthermore, since vertical and horizontal members can be securely fastened, buckling is prevented, thereby preventing safety accidents.

[0006] These system supports are generally composed of vertical members, horizontal members, and bracing members.

[0007] The vertical members directly support the load of the formwork and are configured to be height-adjustable by combining an inner tube and an outer tube, and a U-head is provided at the top to support the yoke. Adjacent vertical members are connected and supported by horizontal members.

[0008] To connect the above horizontal member to one side of the vertical member, a flange is provided on the outside of the vertical member, and a connector is provided at the end of the horizontal member, which is fixed to the flange by fastening a fixing pin.

[0009] At this time, the above flange is fixed to the vertical member by welding, or screw-coupled to the vertical member by forming screw threads on its inner surface.

[0010] However, in the case of welding, there is a disadvantage in that the height of the flange cannot be adjusted, making it difficult to adjust the vertical spacing of the horizontal members.

[0011] In addition, screw connections are cumbersome because they require forming separate screw threads on the vertical member to connect the flange, or installing the flange only at the part where the connector is connected to secure the fixing pin. The problem to be solved

[0013] To solve the above-mentioned problems, the present invention aims to provide a system support with easy height adjustment of the horizontal member, which can ensure constructability and safety of the system support by allowing the installation position of the horizontal member to be freely adjusted. means of solving the problem

[0015] According to a preferred embodiment, the present invention comprises: a plurality of vertical members spaced apart from each other; a flange member configured to be vertically movably coupled to the vertical members and surrounding the exterior of the vertical members, the flange comprising a guide tube having a cut hole formed therein and a plurality of wing portions protruding laterally, with a fastening hole formed in the wing portion and the flange member being provided at the upper end of the guide tube; a horizontal member having a horizontal insertion groove formed at the front into which the wing portion of the flange member is inserted, a vertical insertion groove formed penetrating vertically to communicate with the fastening hole, and a connecting hole provided at both ends having a front lower portion penetrating the cut hole and coupled to a pair of adjacent vertical members; and a fixing pin formed to be penetratingly coupled to the vertical insertion groove of the connecting hole and the fastening hole of the flange member, the fixing pin being formed such that its width increases toward the top. A system support for easy height adjustment of a horizontal member is provided, characterized by being composed of such that when the fixing pin is lowered while inserted into the vertical insertion groove and the fastening hole, the connecting member moves toward the vertical member side by the inclined surface of the fixing pin, the front end of the connecting member comes into close contact with the side of the vertical member, and the inner surface of the opposite side of the guide tube comes into close contact with the vertical member.

[0019] According to another preferred embodiment, the present invention provides a system support for a horizontal member that facilitates height adjustment, characterized in that the upper end of the guide tube protrudes above the upper flange.

[0020] According to another preferred embodiment, the present invention provides a system support that facilitates height adjustment of a horizontal member, characterized in that a magnet insertion hole into which a magnet is inserted is formed in the guide tube. Effects of the invention

[0022] According to the present invention, a system support that facilitates height adjustment of a horizontal member can be provided, wherein a flange member is vertically movably coupled to a vertical member to join a horizontal member to the side of a mutually spaced vertical member, and a connector that is coupled to the flange member is provided at both ends of the horizontal member.

[0023] In particular, since the cylindrical guide tube constituting the flange member is connected to the vertical member so as to be movable up and down, the installation position of the horizontal member can be freely adjusted by adjusting the height of the flange member.

[0024] In addition, the vertical member can be joined to the end of the horizontal member simply by inserting a fixing pin through the vertical insertion groove formed vertically in front of the connector and the fastening hole of the wing portion protruding laterally from the top of the flange member, thus providing excellent constructability.

[0025] In addition, if the fixing pin is formed so that its width increases toward the top, the flange member is pulled toward the connector side and fixed in close contact with the vertical member upon insertion of the fixing pin, thereby preventing vertical movement of the flange member and ensuring safety.

[0028] The present invention will be described in detail below according to the attached drawings and preferred embodiments.

[0030] FIG. 1 is a perspective view illustrating a system support for the horizontal member of the present invention that allows for easy height adjustment. FIG. 2 is a perspective view illustrating a flange member, FIG. 3 is a perspective view illustrating a horizontal member, and FIG. 4 is a perspective view illustrating the connection relationship between the flange of the flange member and the connecting member of the horizontal member.

[0031] As illustrated in FIGS. 1 to 4, etc., the system support for easy height adjustment of the horizontal member according to the present invention comprises: a plurality of vertical members (1) spaced apart from each other; a flange member (2) configured to be vertically movably coupled to the vertical members (1), comprising a guide tube (21) that surrounds the exterior of the vertical members (1), a plurality of wing portions (221) protruding laterally, and a fastening hole (222) formed in the wing portion (221) and a flange (22) provided at the upper end of the guide tube (21); and a horizontal member (3) coupled to an adjacent pair of vertical members (1), wherein a horizontal insertion groove (311) into which the wing portion (221) of the flange member (2) is inserted is formed at the front, and a connector (31) is provided at both ends, wherein a vertical insertion groove (312) penetrating vertically to communicate with the fastening hole (222) is formed. It is characterized by being composed of: a fixing pin (4) that is coupled through the vertical insertion groove (312) of the connector (31) and the fastening hole (222) of the flange member (2).

[0032] The present invention is intended to provide a system support with an easy-to-adjust horizontal member height, which can ensure constructability and safety of the system support by allowing the installation position of the horizontal member (3) to be freely adjusted.

[0033] The system support for the horizontal member of the present invention, which allows for easy height adjustment, is configured by interconnecting a plurality of vertical members (1) with horizontal members (3).

[0034] The above vertical member (1) can be configured to be height-adjustable by inserting an inner tube (12) into the outer tube (11).

[0035] The above vertical members (1) are provided in multiple numbers spaced apart from each other.

[0036] The vertical members (1) spaced apart from each other are connected and supported by horizontal members (3).

[0037] In order to join a horizontal member (3) to the side of the vertical member (1), a flange member (2) is provided on the vertical member (1), and a connector (31) that is coupled to the flange member (2) is provided at both ends of the horizontal member (3).

[0038] The above flange member (2) is formed in a cylindrical shape and consists of a guide tube (21) that surrounds the outside of the vertical member (1) and a flange (22) provided at the top of the guide tube (21) (Fig. 2).

[0039] The above guide tube (21) is connected to the vertical member (1) so as to be movable up and down. Accordingly, the flange member (2) can be positioned at any location on the vertical member (1), and the height and number of horizontal members (3) supporting the vertical member (1) can be freely adjusted.

[0040] The above flange (22) is formed in the shape of a plate and is provided on the upper end of the flange member (2).

[0041] The above flange (22) has a circular through hole (220) formed in the center so that a vertical member (1) can pass through, and a plurality of wing portions (221) are formed protruding laterally at the outer end.

[0042] The above wing portion (221) is a part that is inserted into the connector (31) to be described later and combined with the horizontal member (3).

[0043] Each wing portion (221) has a fastening hole (222) formed that penetrates vertically for connection with a connector (31).

[0044] At both ends of the horizontal member (3), a connecting member (31) is provided for connection with the flange member (2).

[0045] A horizontal insertion groove (311) into which the wing portion (221) of the flange (22) is inserted is formed by cutting horizontally in front of the connector (31), while a vertical insertion groove (312) penetrating the connector (31) in a vertical direction is formed (Fig. 3).

[0046] The vertical insertion groove (312) is formed at a position corresponding in the vertical direction so as to communicate with the fastening hole (222) of the wing portion (221) when the wing portion (221) of the flange (22) is inserted into the connector (31) through the horizontal insertion groove (311) (Fig. 4).

[0047] With the wing portion (221) of the flange member (2) inserted into the above connector (31), a fixing pin (4) is inserted through the vertical insertion groove (312) and the fastening hole (222).

[0048] The connector (31) and the flange (22) are simply and easily fixedly joined by the above fixing pin (4), so that the end of the horizontal member (3) is joined to the vertical member (1).

[0050] FIG. 5 is a cross-sectional perspective view illustrating the fixed state of the flange by a fixing pin.

[0051] As shown in FIG. 5, the fixing pin (4) is formed so that its width increases toward the top, and can be configured so that when the fixing pin (4) is inserted, the flange member (2) is pulled toward the connector (31).

[0052] Since the guide tube (21) of the above flange member (2) must be connected to the vertical member (1) so as to be vertically movable, its inner diameter is configured to be larger than the outer diameter of the vertical member (1).

[0053] At this time, in order to fix the position of the flange member (2) to the vertical member (1) at a desired height, the guide tube (21) of the flange member (2) can be configured to be in close contact with the vertical member (1) by means of a fixing pin (4).

[0054] The above fixing pin (4) can be configured so that its front-to-back width increases as it goes upward.

[0055] When the wing portion (221) of the above flange member (2) is inserted into the horizontal insertion groove (311) of the connector (31), the fastening hole (222) is positioned further outward than the vertical insertion groove (312) and is arranged so as to be offset from each other.

[0056] At this time, when the above fixing pin (4) is lowered while inserted into the vertical insertion groove (312) and the fastening hole (222), the connecting member (31) moves toward the vertical member (1) due to the inclined surface of the fixing pin (4), the front end of the connecting member (31) comes into close contact with the side of the vertical member (1), and the flange member (2) is pulled toward the horizontal member (3).

[0057] Accordingly, on the opposite side of the connector (31), the inner surface of the guide tube (21) is in close contact with the vertical member (1), and the flange member (2) is fixed to the vertical member (1) by the frictional force between the guide tube (21) and the vertical member (1). And on the side of the connector (31), the front of the connector (31) is in close contact with the vertical member (1), and the connector (31) is fixed to the vertical member (1) by the frictional force between the connector (31) and the vertical member (1).

[0058] That is, by simply fastening the above fixing pin (4), the flange member (2) is fixed to the vertical member (1) and vertical movement is prevented.

[0060] FIG. 6 is a perspective view illustrating a flange member having a toothed portion formed thereon.

[0061] As shown in FIG. 6, a toothed section (211) may be formed in the circumferential direction on the inner surface of the guide tube (21).

[0062] In order to prevent the flange member (2) from sliding downward due to a vertical load while the inner surface of the guide tube (21) is fixed in close contact with the vertical member (1), a toothed portion (211) may be formed on the inner surface of the guide tube (21).

[0063] The above-mentioned toothed portion (211) may be formed in multiple rows in the circumferential direction on the inner surface of the guide tube (21). It is preferable that the above-mentioned toothed portion (211) be formed with a downward slope to prevent the flange member (2) from descending.

[0065] FIG. 7 is a perspective view illustrating a flange member with the lower part of the cut hole open.

[0066] As illustrated in FIGS. 2, 5, 7, etc., the guide tube (21) may have an opening (212) formed therein so that the connector (31) can pass through and be attached to one side of the vertical member (1).

[0067] The flange (22) of the above flange member (2) has a wing portion (221) that is inserted into a horizontal insertion groove (311) formed by cutting into the front center of the connector (31), and when the fixing pin (4) is fastened, the connector (31) must be fixed in close contact with the vertical member (1).

[0068] However, the above flange member (2) is provided with a guide tube (21) at the bottom of the flange (22) and interferes with the connector (31). Therefore, the connector (31) can only be in close contact with the side of the vertical member (1) at the top of the flange member (2), making it difficult to exert sufficient frictional force, and eccentricity may occur between the connection point between the connector (31) and the vertical member (1) and the flange (22), which may reduce stability.

[0069] Accordingly, an incision hole (212) may be formed in the guide tube (21) so that the above connector (31) can be in close contact with the vertical member (1) at the upper and lower parts of the flange (22).

[0070] The above-mentioned cut holes (212) can each be formed at positions corresponding to the wing portion (221) of the flange (22).

[0071] The above-mentioned cut hole (212) can be formed to be larger than the width of the connector (31) so that the connector (31) can pass through it.

[0072] Accordingly, when the above fixing pin (4) is fastened, the lower part of the front of the connector (31) can pass through the cut hole (212) and be fixed in close contact with the side of the vertical member (1) (Fig. 5).

[0073] The lower part of the above-mentioned incision (212) may be closed as in FIG. 2 or open as in FIG. 7.

[0075] The upper end of the guide tube (21) may protrude above the flange (22).

[0076] When the guide tube (21) is fastened with the fixing pin (4), the inner surface opposite the connector (31) is in close contact with the vertical member (1).

[0077] At this time, the guide tube (21) can be configured so that its upper end protrudes above the flange (22) in order to increase the friction area by ensuring that the guide tube (21) is in close contact with the vertical member (1) not only at the lower end but also at the upper end of the flange (22), and to minimize the eccentricity between the friction surfaces of the flange (22) and the guide tube (21) where the pulling force applied by the fixing pin (4) is applied.

[0078] When an incision hole (212) is formed in the guide tube (21), the incision hole (212) may be configured to extend to the top of the guide tube (21) and open upward so that the part of the guide tube (21) protruding above the flange (22) does not interfere with the connector (31).

[0080] FIG. 8 is a perspective view showing a flange member having a magnet insertion hole formed therein, and FIG. 9 is a perspective view showing the flange member temporarily fixed to a vertical member by a magnet.

[0081] As shown in FIGS. 8 and 9, a magnet insertion hole (213) into which a magnet (5) is inserted may be formed in the guide tube (21).

[0082] When the flange member (2) is fixed to the vertical member (1) by fastening the above fixing pin (4), the position of the flange member (2) is not fixed until the fixing pin (4) is fastened, so the installation work may be cumbersome.

[0083] Accordingly, a magnet (5) may be provided to temporarily fix the position of the flange member (2) until the fixing pin (4) is fastened.

[0084] To this end, a magnet insertion hole (213) into which a magnet (5) is inserted may be formed through the guide tube (21).

[0085] When the flange member (2) is moved up and down to reach a desired height, a magnet (5) can be inserted into the magnet insertion hole (213) so that the magnet (5) is attached to the side of the vertical member (1). Then, the magnet insertion hole (213) is caught on the magnet (5), so that the flange member (2) does not move up and down and is fixed in a vertical position.

[0086] After the flange member (2) is fixed to the vertical member (1) by fastening the above fixing pin (4), the magnet (5) can be removed. Explanation of the symbols
