Description

Technology Field

[0001] This invention relates to a variable tie for angle and length adjustment capable of adjusting the angle and length, and in particular, to a variable tie for angle and length adjustment capable of adjusting the angle and length that ensures sufficient support while maintaining a constant distance between a composite wall formwork and a support pile equipped with a retaining plate. Background Technology

[0003] Generally, multi-story high-rise building structures are constructed by repeating the process of reinforcing steel in the ground floor, building a concrete floor surface, and then setting up formwork vertically or horizontally on the floor surface to fill with concrete.

[0004] A concrete composite wall is a wall constructed during basement construction where one side is supported by the soil layer of the excavated underground space and formwork is installed only on the other side; it is constructed while supported by a composite wall support.

[0005] The composite wall support is configured such that a vertical support bar, which is provided adjacent to the formwork in a triangular truss shape, is connected to a horizontal support bar in a direction perpendicular to the lower end, and while both ends of the vertical support bar and the horizontal support bar are each connected obliquely by a connecting bar, a fixing part is provided at the point where the vertical support bar and the horizontal support bar intersect, and the fixing part is configured to be connected to an anchor bolt protruding above the floor concrete by passing through it and joining with a nut.

[0006] There was a problem in that the lower part of the wall support was simply supported by anchor bolts embedded in the floor concrete, and thus could not sufficiently resist the lateral pressure of the concrete during the concrete pouring process, resulting in bulging.

[0007] Meanwhile, regarding such conventional technology, a connection structure between a retaining wall and a concrete underground wall using a king pile for a retaining wall was proposed in Registered Patent Publication No. 10-0633013 (September 29, 2006). In the proposed underground wall, one side of the formwork support is screw-coupled to the fixing member of the king pile, and the other side of the formwork support penetrates the formwork and is connected by a fixing means, thereby allowing concrete to be poured into the interior to integrate the retaining wall and the concrete underground wall, thereby increasing the rigidity of the concrete underground wall and minimizing the work required for installing the formwork for wall construction. However, there were many difficulties in the process of aligning the center of the formwork support with the center of the fixing member and connecting them, and there was a problem of low workability because the formwork support was only provided in a direction perpendicular to the king pile and could not be changed to an arbitrary angle.

[0008] In addition, there was a problem where the formwork could not be reused because it was damaged during the process in which the other side of the formwork support penetrated the formwork and was joined by a fixing means. Prior art literature

Specific details for implementing the invention

[0029] An embodiment of the invention is described below with reference to the attached drawings.

[0032] The angle and length adjustable variable tie (A) according to the present invention prevents damage and deformation caused by penetration of the existing composite wall formwork, thereby extending its lifespan and enabling repeated reuse, and achieves high workability to reduce the cost and time required for construction. As shown in FIGS. 1 to 6, it is provided between the composite wall formwork (MP) and the support pile (SP) equipped with the earth retaining plate (RP).

[0033] To this end, the variable tie (A) is provided with a length-adjustable flat tie (10), a circular tie (20), a hook (30), a fixing bracket (40), a sleeve (50), and a nut (60).

[0034] Here, the length-adjustable flat tie (10) is positioned on one side, while the circular tie (20) is provided on the other side, and the hook (30) is screw-coupled to the other side of the circular tie (20), so that the hook (30) provided on the other side of the circular tie (20) is hooked into the hook hole (401) of the fixing bracket (40) provided on the front of the support pile (SP), thereby enabling angle adjustment.

[0035] On the other side of the length-adjustable flat tie (10), the cylindrical sleeve (50) is joined by a welded joint (WJ), and one side of the circular tie (20) is inserted through and exposed into the sleeve (50) provided on the other side of the length-adjustable flat tie (10), and is screw-coupled with the nut (60) to enable length adjustment.

[0036] The above-mentioned length-adjustable flat tie (10) has one end formed flat so that it can easily pass between the joint wall formwork (MP) and the adjacent joint wall formwork (MP), and the flat end of the length-adjustable flat tie (10) is provided with a wedge pin hole (101) into which a wedge pin (WP) is inserted, and a notch groove (102) is provided on the inside of the wedge pin hole (101).

[0037] The above notch groove (102) is positioned at a certain distance from the inner wall of the composite wall formwork (MP) so that it is embedded in the poured concrete, and when the concrete is cured and the composite wall formwork (MP) is separated, if tension is applied using a separate tool, the part equipped with the notch groove (102) is cut, thereby preventing a part of the length-adjustable flat tie (10) from being exposed to the outside.

[0038] At the other end of the length-adjustable flat tie (10), an inwardly inclined inclined portion (10a) is provided by being bent, and a horizontal portion (10b) is provided by being bent at the other end of the inclined portion (10a), so that the cylindrical sleeve (50) is joined to the horizontal portion (10b) by a welded joint (WJ), thereby ensuring sufficient support.

[0039] This is so that one side of the circular tie (20) is inserted through and exposed in the sleeve (50) provided on the other side of the length-adjustable flat tie (10), and when the nut (60) is screwed into the male screw portion (MS) on one side of the circular tie (20), a space is formed between one side of the circular tie (20) and the length-adjustable flat tie (10) to facilitate the screwing or loosening of the nut (60).

[0040] It is preferable that the outer diameter of the sleeve (50), which is joined to the other horizontal portion (10b) of the flat tie (10) by a welded joint (WJ), be wider than the width of the horizontal portion (10b). This is to ensure a more complete weld between the other horizontal portion (10b) of the flat tie (10) and the sleeve (50).

[0041] The above circular tie (20) is provided with a male screw (MS) on part or all of its outer circumference, and a nut (60) is screwed into one end and a hook (30) is screwed into the other end so as to be movable in the axial direction.

[0043] The outer circumference of the above-mentioned hook body (310) is provided to have a shape that is either circular or curved, and a female screw (FS) is formed to penetrate the interior so as to be screw-coupled to the male screw (MS) of the circular tie (10).

[0044] The outer side of the hook piece (320) is formed as a gentle curved portion (321), and the inner side is formed as an L-shaped hook portion (322), so that when the hook (30) is hooked into the hook hole (401) of the fixing bracket (40) described later, the hook (30) can be arbitrarily angle-adjusted in the hook hole (401) and is not easily detached by the L-shaped hook portion (322).

[0045] The above-mentioned fixed bracket (40) is bent into an L-shape so that the vertical portion is butted against the support pile (SP) and joined by a welded joint (WP) to maintain sufficient fixing force, and the horizontal portion is provided with four or more hanging holes (401) in the horizontal direction so that the hanging angle of the above-mentioned hanging member (30) can be easily adjusted, and it is preferable that these hanging holes (401) have a circular shape.

[0046] The sleeve (50) is configured so that the length-adjusted state can be maintained by having a nut (60) hooked onto the end of the sleeve (50) at a specific position, while allowing the circular tie (20) to move easily inside to adjust the length.

[0047] To this end, the sleeve (50) is provided on the other side of the length-adjustable flat tie (10), and has a through hole (501) inside the body so that the circular pie (20) can freely reciprocate.

[0048] After one side of the circular tie (20) is inserted through and exposed into the sleeve (50) provided on the other side of the length-adjustable flat tie (10), a nut (60) is screw-coupled to the side of the circular tie (20) exposed through the sleeve (50) so that it can be fixed (pulled) and maintained.
