Description

Variable type detachable beam deck system

The present invention stacks the inner and lower decks and side decks of two or more support frames that match the width and height of the beams to be constructed, so as to be easy to assemble and construct in the field according to the width and height of the beams. It relates to a variable demolding beam deck system that is easy to demold (dismantle) even after beam construction is completed.

In general, the formwork for making a ceiling beam formed by curing concrete to enter only the reinforcing steel frame is used by combining wood panels one by one, so it takes a lot of work time and wastes manpower. The waste of materials that are used only once has been caused. Especially, the wooden formwork is made of expensive wood because of its low durability due to its material characteristics, so it has low economic value due to the defect that it can be reused only a few times (5-6 times). It is accompanied by a problem.

A conventional prefabricated iron formwork for rebar concrete structural ceiling beam structures (see Patent Document 1) for solving this, as shown in FIG. 26, in constructing a ceiling beam formwork installed under the deck plate (D), the deck plate (D) An iron panel (1) connecting the lower part of the formwork and the two side panels by the lower guide (8) installed on the upper guide (2) attached to the bottom surface and the b-beam member (9) supported on the panel support (4). The panel support (4) in which the panel assembly means (6) (6') equipped with the panel assembly means and the barge strip (5) having a height adjustment bar (5') are installed on both sides is a well-known support steel pipe. An iron formwork having a beam structure space (P) is made by a panel support means that is supported by (3) to support the iron panel (1).

However, since the bottom and side surfaces of the single iron panel 1 are configured, an iron panel 1 suitable for a change in length must be provided, and the single iron panel 1 is equipped with a trouser stand 6, 6'. It is very difficult to install on a crane and so on.

On the other hand, another conventional variable beam formwork 100 (see Patent Document 2), as shown in Figures 27 to 29, the support member 102 and the support member 102, which is installed on the upper portion of the support 110 The first and second formwork (120,130) which is slidably installed along the longitudinal direction from the upper part of the guide nut (142,144) coupled to the lower part of the first and second formwork (120,130) and having a female thread formed on one side, and both sides It is configured to include a working bolt 150 formed with a male screw portion 152 of the left screw structure and a male screw portion 154 of the right screw structure, which are fastened to the female screw portions of the guide nuts 142 and 144, respectively.

The support 110 includes an outer surface 112 coupled to the supporting member 102, an extender 112 connected to the lower end of the outer surface 112, and the extender 114 in the state inserted into the lower end of the extender 114. 114) and a pin (116) fixed through the pin (117).

The first and second dies 120 and 130 are composed of lower plates 122 and 132 for forming the lower surface of the beam, and side plates 124 and 134 for forming both side surfaces of the beam, and lower plates 122 and 132 and the side plates 124 and 134. Are mutually coupled in a vertically arranged state.

On the other hand, when the gap between the first and second dies 120 and 130 is widened and the gap between the two lower plates 122 and 132 is increased, an empty space is generated between the gaps, and the lower dies of the beam are provided in the empty space with both lower plates 122 and 132. To form a surface, a plate-shaped insert plate 180 having a horizontal width size corresponding to an interval between the lower side plates 122 and 132 is installed.

However, the configuration of forming an empty space for installation of the insert plate 180 is very complicated.

In addition, since the lower plates 122 and 132 and the side plates 124 and 134 are integrally combined, in order to adjust the side height of the beam, first and second dies 120 and 130 having different side lengths must be prepared for each construction site. It is economical.

On the other hand, the pillar (copper) of Patent Documents 1 and 2 is a common one, and it is necessary to manually fix the post (copper) between pillars and pillars according to the width of the formwork. It takes effort.

In addition, it is very difficult to mount the beam formwork by precisely aligning the width center of the formwork with the width center of the post. In other words, even if the width sensor of the prop is correct, it is very difficult to mount it in line with the lifted beam formwork sensor, so it takes a lot of time and effort to mount.
