The present invention relates to a sliding end panel, and more particularly, the side end or the upper end of the concrete wall is finished by the front panel, but separates a plurality of horizontal members fixing the front panel and the front panel, respectively, the length of the front panel A guide bar having a "c" shaped cross section in the direction, and by attaching a fitting of the "c" shaped cross section to a plurality of horizontal members so that the horizontal member is slidable up and down along the guide bar, the conventional formwork and the horizontal member are fastened The present invention relates to a sliding end panel that can improve the difficulty of fastening with a wedge-shaped fastening means because the holes do not fit.

In general, the formwork system is to form a form having a predetermined shape in advance in various construction and civil works such as houses, apartments, buildings, dams, bridges, tunnels, water and sewerage, subway construction, and then cast concrete in the space and sufficiently cured It is used to separate and disassemble formwork.

Such conventional formwork can be broadly divided into those using wood, plywood and the like and those using iron plates. The formwork of the wood or plywood material is made in a simple way to form a mold by nailing the plate and the plate together, so that not only a lot of manpower and time is required during the assembling and dismantling work but also such as assembly and separation and dismantling work is repeated. Therefore, the connection part of the plate is damaged, there is a disadvantage that the service life is not long.

Therefore, the steel concrete formwork is easier to assemble and dismantle than the wooden concrete formwork, and the bonding strength is excellent when the formwork is connected to the formwork to obtain a flat concrete wall surface, and the durability is excellent and can be reused repeatedly for a long time. There are advantages to it.

On the other hand, in a formwork system, a formwork edge panel is used to form a space portion where a door frame or window frame is coupled to a predetermined position of a concrete wall.

However, the conventional formwork edge panel is not supported by the side panel when placing concrete, because the front panel (flat tie) made of thin plywood is supported by the support wood and the spacer so that the center part of the front panel is not supported. I can't.

Therefore, as the center portion of the front panel is deformed outward and the fixing nails fixed to the support tree are separated, the corners of the retaining wall are not even after the concrete is cured, and thus there is a problem that the construction of the window and the window frame cannot be performed smoothly.

In addition, since the support wood and the spacer is made of wood, the weight is light and easy to carry and the manufacturing cost is low, but there is a problem that the life is short, the assembly process is difficult, and precise construction is impossible.

In order to solve such a conventional problem, various types of sliding end panels have been proposed and used in recent years, and have been filed on May 9, 1995 (application number 1995-009759), as shown in FIGS. 5 and 6.

The 130 is coupled by welding, and a plurality of horizontal members 140 are welded in the horizontal direction to the outside of the vertical member 120 facing the front panel 110.

In this case, fixing holes 142 are formed at both ends of the plurality of horizontal members 140, and the wedge-shaped fixing means 150 penetrates the vertical member 160 of the formwork through the fixing holes 142. The other wedge-shaped fixing means penetrates in the vertical direction to the coupling hole 152 formed in the wedge-shaped fixing means 150, thereby fixing the edge panel to the formwork.

However, since the horizontal member is pre-welded to the vertical member at regular intervals, the coupling hole formed in the vertical member of the formwork used in the actual construction site and the fixing hole of the horizontal member are often inconsistent in manufacturing or construction. There is a hassle that needs to be reconstructed after blowing the horizontal member with oxygen in the field.

The present invention has been made in view of the above, the front panel is attached to the guide bar of the "c" shaped cross-section in the longitudinal direction, the "c" shaped cross-section of the plurality of horizontal members each attached to the guide portion of the guide By sliding on the bar, the horizontal member is adjusted up and down according to the site situation, fits into the fastening hole of the formwork, and then is fastened by the wedge-shaped fastening means.
