SUPPORT INTEGRATED WAFFLE FORM SYSTEM FOR WAFFLE SLAB AND CONSTRUCTION METHOD FOR THE SAME

The present invention relates to a waffle slab formwork system and a construction method thereof, and more particularly, to a support-integrated waffle slab formwork system in which the formwork support is integrally formed with the waffle slab formwork to facilitate installation, movement and demolding of the formwork; It is about the construction method.

In general, a reinforced concrete structure structure is constructed by installing a formwork, placing reinforcing bars inside the formwork, and then pouring concrete. In the construction of such reinforced concrete structures, the formwork installation process is necessarily followed. The formwork installation process takes a lot of time and manpower, as well as a lot of time and money to dismantle the concrete after hardening. have.

Various methods have been proposed to reduce the cost and time required for the formwork installation process. Among them, building-type structures such as apartments are standardized to a certain standard, so installation and dismantling are easy and can be used repeatedly several times. Euroform and table form for a formwork having a form are widely used.

However, even in the case of such a Euroform or table form for a formwork, since many supports must be installed, not only a lot of time and money is required to install the supporter, but also the installation and manufacturing of the Euroform formwork itself is cumbersome and complicated.

On the other hand, the waffle slab, which is used as a method of reducing the weight of the slab, does not increase the height of the floor and can be expected to be lightweight without increasing its own weight. The formwork was difficult to install, dismantle, and reuse, and its use was limited due to the increase in temporary construction cost.

Hereinafter, with reference to the accompanying drawings, a support-integrated waffle slab formwork system and a construction method thereof according to the present invention will be described in detail as examples.

1 to 7 , the support integrated waffle slab formwork system according to the present invention includes a plurality of waffle forms 20 and a support assembly 10 .

The support assembly 10 is provided under the waffle foam to support the waffle foam, and as shown in FIGS. 8A to 8C , it is composed of a unit module having a certain area and is disposed around the pillar 3 of the structure.

The support assembly 10 includes an upper support assembly 100 and a lower support assembly 110 .

The lower support assembly 110 includes a vertical member 111 and a horizontal member.

In this embodiment, the vertical member 111 is formed of a copper pipe, and it is assumed that four vertical members are installed in one support assembly 10 . The vertical member 111 is composed of an exterior 300 and an inner tube 400, and the inner tube 400 is inserted into the exterior and is configured to be fixed at a predetermined position according to the user's needs. It is designed to be adjustable in height.

The exterior is formed of a copper pipe, and a connecting flange to which the horizontal pipe of the horizontal member is fastened is formed on the outer circumferential surface of the exterior. The connecting flange is installed in a pair of upper and lower sides on the outer peripheral surface of the exterior, and after the fastening head 141 of the horizontal pipe is inserted, a fastening pin 142 is inserted into the fastening hole provided in the connecting flange to be connected to the horizontal pipe. is composed

As shown in FIGS. 10 to 16 , the vertical member 111 includes an exterior 300 , an inner tube 400 , a position fixing part 330 , and a fastening fixing part 500 .

A position fixing part 310 is provided at the other end of the exterior. The position fixing part 310 has a screw thread formed on its outer circumferential surface, and the locking handle 330 moves up and down while screwing with the screw thread to be positioned at a desired position. Elongated slits are formed in the mounting fixing part 310 to insert a locking pin into the locking handle 330, and the locking pin is inserted again into the locking hole of the inner tube to fix the position of the outer tube and the inner tube. do.

The outer tube 400 is accommodated in the outer tube (300). The inner tube 400 has a smaller diameter than the outer tube is accommodated in the outer tube is configured to be able to ascend or descend from the outer tube.

Since the inner tube 400 is configured to have a smaller diameter than the outer tube, there is inevitably a gap or shaking between the inner tube 400 and the outer tube while being inserted into the outer tube. Conventionally, it is attempted to minimize the gap or shake between the inner tube and the outer pipe by securing a sufficient overlap length, but even if the overlap length is long, there is no choice but to cause gap or shake, and if the overlap length is long, it is disadvantageous in economic feasibility and constructability as described above. will do

The vertical member of the present invention has a fastening fixing part 500 to solve this problem.

The fastening fixing part 500 is formed to surround the exterior. The fastening fixing part 500 is configured to press the outer tube and the inner tube to prevent shaking between the outer tube and the inner tube.

The fastening fixing part 500 includes a fastening fixing body part 501 , a ball receiving part 502 , and a fastening fixing ball 510 .

The fastening and fixing body portion 501 is formed in a substantially ring shape or a bracelet shape and is formed of a plastic material or a metal material to surround the exterior.

The ball receiving portion 502 is formed by being spaced apart at a predetermined interval along the circumference of the tightening and fixing body portion 501 .
