Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a beam form supporting frame for supporting a floor form and a beam form immediately after placing concrete.

[Conventional technology]

Immediately after placing concrete, floor and beam forms need to be supported for a considerable period of time by concrete support until the concrete shows sufficient strength, but conventionally, beam forms are supported from below by pipe supports, etc. Was common, which was an obstacle to the passage of workers.

The pipe support is extremely convenient because its length can be freely changed, but since it is necessary to install many pipe supports one by one, its installation and management were extremely troublesome.

For this reason, in recent years, various beam form supporting frames dedicated to the beam form have been devised in order to reduce the use of the pipe supports and to simplify the assembly of the supporting work as much as possible.

Most of them are installed on the lower side of the beam formwork at a right angle to this, and are supported by at least two pipe supports.
The configuration is such that the level is adjusted by appropriately changing the length of the pipe support, and the present applicant has also developed and implemented some of them.

[Problems to be solved by the device]

However, according to this type of beam form supporting frame, when the beam form is almost the same or not so different, one type of beam form supporting frame is sufficient, but when the beam form is largely different, the supporting frame is Since the vertical movement of the robot becomes large, it is not only difficult to adjust the level, but it is not possible to deal with one type, and several types of beam formwork support frames are required.

Also, at least two pipe supports were required under the beam formwork, and there was a long way to go before the pipe supports were largely omitted.

The present invention has been made in order to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a beam form frame support frame capable of supporting beam form frames of one type, which are greatly different in beam formation. To aim.

[Means for solving the problem]

A beam form supporting frame according to the present invention includes an upper horizontal rod and a lower horizontal rod, which are installed under the beam form to be constructed so as to be orthogonal to the beam form, and the upper horizontal rod. A plurality of intermediate vertical rods which are erected at predetermined intervals between the lower horizontal rods,
