In paragraph 2, Each of the first adjusting member (215) and the second adjusting member (225) is, It has a "∩" shaped cross-section, At each other end, an extension piece (330) extending outwardly toward the first adjusting member (215) and the second adjusting member (225); These are provided side by side, The above-mentioned locking pin (320) is mounted to pass through the above-mentioned extension piece (330) facing it side by side, and The first length member (210) and the second length member (220) each pass through the space between the "∩" shaped cross section of each of the first adjustment member (215) and the second adjustment member (225) and the locking pin (320). When the first adjusting member (215) and the second adjusting member (225) are each rotated to form an incline with the first length member (210) and the second length member (220), respectively, the space between the "∩" shaped cross section of the first adjusting member (215) and the second adjusting member (225) and the locking pin (320) is expanded, causing the locking pin (320) to disengage from the locking groove (310), thereby enabling movement of the first adjusting member (215) and the second adjusting member (225), respectively. When the locking pin (320) moves to the position of the locking groove (310), the first adjusting member (215) and the second adjusting member (225) are each rotated to overlap parallel to the first length member (210) and the second length member (220), respectively. A self-supporting, non-dismantling beam formwork fixing device characterized in that a locking pin (320) engages with the locking groove (310) to prevent movement of the first adjusting member (215) and the second adjusting member (225).
  4. In any one of paragraphs 1 through 3, The coupling projection (340) provided at one end of each of the first adjusting member (215) and each of the second adjusting member (225) is, column portion (341); and, A head portion (342) having a cross-section that is more extended than that of the column portion (341) at the end of the column portion (341); It consists of, The above head portion (342) is characterized by having a cross-section that can pass through the insertion portion (151) of the fixing device coupling hole (150) of the self-supporting non-dismantling beam formwork but cannot pass through the seating portion (152).

Description

Self-supporting non-removable beam formwork and fixing device The present invention relates to a fixing device capable of preventing deformation of a prefabricated beam formwork without stirrups being connected, and a self-supporting, non-dismantling beam formwork that can be used with such a fixing device. Generally, beams are installed below the ceiling of a building, and to form these beams, beam formwork capable of pouring concrete is installed. Conventional beam formwork is primarily made of plywood and is mostly demolding type, meaning it is removed once the concrete hardens. However, as such demolding forms reduce work efficiency and cause problems such as damage to the exterior surface of the concrete during dismantling, non-dismantling beam formwork is increasingly being used recently. Recently used non-dismantling beam formwork utilizes materials such as steel, and for economic reasons, thin plate structures are welded or bent for use. The prior art related to this is as follows. (1) Registered Patent No. 10-2211478 is a non-dismantling beam formwork including a recessed space formed to allow concrete to be poured, as shown in FIG. 1, comprising: a lower unit positioned at the bottom of the recessed space and including a bottom portion and a pair of ribs formed by bending from both ends of the bottom portion and extending toward a first direction to support the bottom of the recessed space; and a pair of first side units positioned at both lower corners of the recessed space and connected to both sides of the lower unit, each comprising a bottom portion connected to the bottom portion of the lower unit, a side portion formed by bending from the bottom portion, and a pair of ribs formed by bending from the bottom portion and the side portion, respectively, and extending toward the recessed space in the first direction, third direction, or fourth direction to support the side and bottom of the recessed space. and at least one pair of second side units disposed on the left and right sides of the recessed space and connected to the first side unit, comprising a side portion and a pair of ribs formed by bending from both ends of the side portion and extending toward the recessed space in the third direction or the fourth direction; wherein, among the two ribs in face-to-face contact, the end of one rib is formed by bending in the fourth direction, and the end of the other rib is formed in a "U" shape including a groove formed in the center so that the end of the one rib is inserted into the groove of the other rib, and the end of the other rib is formed by bending and extending in the first direction, and the inner end thereof includes an insertion groove into which a stirrup reinforced in the recessed space can be inserted, wherein the insertion groove has an opening into which the stirrup is inserted with a width wider than the diameter of the stirrup, thereby enabling correction of the error range of the insertion groove continuously disposed inside the recessed space. The stirrup is inserted up to the inner end of the insertion groove, and the stirrup is capable of three-point welding in the insertion groove, but there is a problem in that a means to prevent deformation of the formwork while being joined to the vertical part of the opposing stirrup is not specifically presented. (2) Registered Patent No. 10-2170355, as illustrated in FIG. 2, is a formwork assembly for constructing a beam that distributes the load of a slab at the bottom of a slab, wherein a lower support plate is formed by bending it at the bottom end so as to be parallel to the ceiling surface of the slab, and a pair of left and right side plates are formed by folding at least one folded part that is formed protruding from the inner vertical surface so that the plates overlap each other, and the ends of a pair of lower support plates extending from the pair of left and right side plates facing each other are joined and fixed to face each other to form a seating part that protrudes to a certain height; The device is characterized by having a plurality of main reinforcing bars aligned in the longitudinal direction of the side plate, and a plurality of stirrup reinforcing bars that are positioned and placed on the seating portion and supported in contact with the folding portion, and is inserted and arranged in the pouring space formed between the left and right pair of side plates and embedded in the concrete filled in the pouring space, wherein the reinforcing bar is characterized by having a plurality of main reinforcing bars consisting of a plurality of upper reinforcing bars and a plurality of lower reinforcing bars, and having a stirrup reinforcing bar formed by bending into a closed cross-section to contact the folding portion while positioning the main reinforcing bars consisting of a plurality of lower reinforcing bars, and having a stirrup reinforcing bar formed by bending into an open cross-section open to the top to conta
