Description

Technology Field

[0001] The present invention relates to a formwork support wailer for constructing a column, which is installed for support on the outer side of a formwork for constructing a concrete column. More specifically, the invention relates to a formwork support wailer for constructing a column that enables simple and rapid fixing and connecting or separating of a supporting means of a support wailer and an adjacent supporting wailer, which are installed intersectingly on the outer side of the formwork. Background Technology

[0003] Generally, the construction of a concrete column involves installing a square formwork outside the reinforced steel and then pouring and curing concrete inside the formwork.

[0004] In this process, the above formwork is installed to be supported by connecting and fixing it to adjacent formworks using fastening pins.

[0005] However, the above formwork could not withstand the strong pressure generated during the concrete pouring and curing process solely through the fastening force of the fastening pins, causing the gaps between the formwork to widen and resulting in a problem where the construction quality of the concrete column deteriorated.

[0006] To address these problems, numerous support waler technologies have been disclosed in Registered Utility Model No. 20-213278, Registered Patents No. 10-907088 and No. 10-1129493, etc., which support the formwork by fixing the support walers together in an intersecting manner along the outer perimeter of the formwork for column construction.

[0007] This conventional support waler is configured with an insertion connection on one side of a square pipe-structured body and an assembly hole on the other side into which the insertion connection is inserted horizontally in an intersecting direction, wherein the assembly hole is composed of a pressure plate and a pressure control unit connected to the pressure plate by a rod to adjust the forward and backward movement of the pressure plate while applying pressure to fix the insertion connection inserted into the assembly hole.

[0008] In particular, the above-mentioned pressure control unit has a rod of the pressure plate spirally coupled inside the rotating handle, and as the rod moves back and forth by the forward and reverse rotation of the rotating handle, the pressure plate is pressure-fixed. Since the operator has to repeatedly rotate the rotating handle to move the pressure plate back and forth during the pressure-fixing operation, the process of fixing and separating the support waler is very difficult and requires a large number of personnel and working time, and there were problems such as a significant decrease in the workability of installing and dismantling the formwork.

[0020] In order to explain the operational advantages of the present invention and the objectives achieved by the implementation of the present invention, preferred embodiments of the present invention are illustrated below and will be examined with reference to the accompanying drawings.

[0021] The column construction formwork support waler (100) of the present invention is configured to support the formwork by being installed in a square shape on each outer side of the column construction formwork (5) as shown in FIGS. 1 to 8, with a support means (10) and a fixing means (20), and then easily and quickly fixedly joined to support the formwork.

[0022] The above support means (10) is formed as a rectangular body (11) having a rectangular cross-sectional structure, and is configured to have a plurality of insertion holes (12) spaced apart along the length direction on one side of the rectangular body (11).

[0023] The above insertion hole (12) may be formed in a circular shape to support the support projection described later, but as shown in the drawing, it is configured to be formed in the shape of a left and right elongated hole to facilitate the insertion of the support projection.

[0024] The above fixing means (20) is configured to be installed on the other side of a rectangular body (11), and comprises a support member (21) inserted into the body (11) and moving along the length direction of the body, front and rear support plates (22a) (22b) protruding forward and rearward from the upper side of the support member and forming an assembly groove (22) into which a support means of an adjacent support waler is inserted, a support pin (24) that supports a support means by being inserted into an insertion hole (12) formed in a support means of an adjacent support waler and a front and rear insertion hole (23a) (23b) formed in a position opposite to the front and rear support plates, a fixing bolt (25) that is fixedly coupled to protrude backward from the rear support plate, a tightening nut (26) that is thread-coupled to the fixing bolt, and a stop plate (14) coupled to one side of the body (11) and inserted and guided into a central guide hole (14a) to prevent the fixing bolt from coming loose.

[0025] At this time, the guide hole (14a) of the stop plate (14) is configured to have a catch (25a) at the rear end of the fixing bolt caught in it to prevent the fixing bolt from moving forward.

[0026] The above support pin (24) is configured to have a cross-sectional structure in which the left and right thickness is thicker than the top and bottom thickness, and to form a catch portion (24a) (24b) protruding left and right at the front and rear ends, and to form a step portion (23c) in the front insertion hole (23a) of the front support plate (22a) to be supported by the catch portion (24a) (24b) of the support pin.

[0027] At this time, the support pin (24) is configured such that a portion including a locking projection on one side is separated and installed by inserting it into the front insertion hole (23a) of the front support plate, and then the remaining separated portion is joined by welding or bolt fastening.

[0028] The above fixing bolt (25) is configured to be fixedly connected to the rear support plate (22b) by means such as welding.

[0029] In addition, the stop plate (14) is installed so as to be spaced apart from the front of the end plate (15) which is coupled to the rear end of the body (11) of the support means, and the end plate (15) is configured to form a through hole (15a) through which the rear end of the fixing bolt can move back and forth.

[0030] At this time, a square pipe (18) is inserted and fixed between the stop plate (14) and the end plate (15) to support the stop plate and the end plate.

[0032] Next, we will examine the operation and function of the present invention configured as described above.

[0033] First, a formwork (5) for constructing a concrete column is installed in a square structure as shown in Fig. 8.

[0034] And four support walers (100) are installed on the outer side of the above formwork (5) so as to intersect each other to support the formwork (5) (see FIG. 1 and FIG. 8).

[0035] To explain this in more detail, a fixing means (20) is installed in an alternating manner on one side of the supporting means (10) of a supporting waler installed on the outside of the formwork and on the other side of the supporting means (10) of a supporting waler adjacent to it.

[0036] That is, the support member (21) of the fixing means provided on the other side of the support means (10) of the support waler adjacent to one side of the support means (10) of the support waler is moved back and forth along the body (11) of the support means so that the support means (10) of the support waler is inserted and supported in the assembly groove (22) formed between the front and rear support plates (22a) (22b) on the upper side of the support member (see FIG. 7).

[0037] At this time, the support pin (24) inserted into the front insertion hole (23a) formed in the front support plate (22a) of the upper part of the support member is pulled forward, so that the catch portion (24b) at the rear of the support pin catches on the step portion (23c) of the front insertion rod to prevent detachment, and does not protrude into the assembly groove (22) inside the front support plate (22a), thereby allowing the support means (10) of the adjacent support waler to be smoothly inserted into the assembly groove (22).

[0038] In this way, the support means of the support member adjacent to the support member (21) can be moved simply and quickly and supported regardless of the distance between them by a one-touch operation that moves the support member (21) back and forth along the support means (10).

[0039] In this state, the support pin (24) inserted into the front insertion hole (23a) of the front support plate is pushed toward the assembly groove (22) and inserted into the multiple insertion holes (12) formed in the support means of the adjacent support waler and the rear insertion hole (23b) of the rear support plate, thereby supporting the support means of the adjacent support waler to be fixedly coupled.

[0040] At the same time, the fixing bolt (25), which is fixedly coupled to protrude backward from the rear support plate (22b), also moves back and forth. The fixing bolt (25) moves back and forth by being guided along the guide hole (14a) formed through the stop plate (14) and the through hole (15a) of the end plate (15) coupled to the rear end of the body (11) of the support means.

[0041] In this state, the tightening nut (26), which is spirally connected to the fixing bolt (25), is spirally rotated so that the tightening nut (26) is pressed and fixed to the stop plate (14), thereby fixing the fixing means of the support waler so that the supporting means of the adjacent support waler does not move back and forth in the supported state.

[0042] In this way, support walers (100) installed crosswise on the outer side of the formwork for building the column are simply and quickly fixedly connected to each other to support the outer side of the formwork.

[0043] Meanwhile, the separation process of the support walers is performed in the reverse order of the aforementioned fixed coupling process by rotating the tightening nut (26) of the fixing bolt (25) in reverse to release the tightening, retracting the support pin, and then separating the support means from the assembly groove of the support member, and moving the support member backward with a single touch to separate the support walers from each other.

[0044] Accordingly, the present invention supports the formwork by installing support walers in a square shape and intersecting them on each outer side of the formwork (5) for building a column, thereby supporting the formwork. In this invention, the support walers are fixedly connected by the tightening operation of a fixing bolt and a tightening nut, by installing a fixing means (20) on the other side of a rectangular support means (10) and moving the support member (21) of the fixing means back and forth with a single touch, thereby inserting the support means (10) of an adjacent support waler into the assembly groove (22) on the upper part of the support member and fixing it in a supported state.

[0046] Although specific embodiments of the present invention have been described above by way of example, these are for illustrative purposes only and are not intended to limit the scope of protection of the present invention. It will be obvious to those skilled in the art that various substitutions, modifications, and changes are possible within the scope of the technical spirit of the present invention.
