JP2000073443A - Load support device having function for deciding position for steel frame column and function for adjusting level - Google Patents

Abstract

PROBLEM TO BE SOLVED: To erect a column at an accurate position by only putting the steel frame column on a product or the like which can not only support a load but also adjust the level. SOLUTION: A spherical round shape is formed on the upper part of a product or the like which can not only support a load but also adjust the level. A spherical diametral recess having the same round shape or a larger shape is formed on a steel member. Assuming that a column to be erected has been erected at an accurate column position where it must be erected, a position of a product or the like which is erected on a foundation concrete at present and can support a load and adjust the level is marked at the lower part of a base plate, and then, steel members are fixed at the positions. When the column is installed on the product or the like which can support the load and also adjust the level through anchor bolts, the upper part of the product and the recess of the steel member are engaged with each other to install the column at the accurate position where it must be positioned.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a product or the like which can support a load of a column and adjust a level when a steel column is to be built in a construction method or the like. The pillars are accurate (naturally) when they are placed on a load-bearing and level-adjustable product (known as iron dumplings, which is partially embedded in the foundation concrete). This is an invention that can be installed at a position of a proper pillar. Conventionally, when building a steel column in a steel frame construction method, the support of the building load and the adjustment of the installation level are performed using products that can support the load and adjust the level (commonly known as iron dumplings partially embedded in the foundation concrete, hereinafter abbreviated). When laying the foundation, adjust the level of the buried load-bearing and level-adjustable products before placing the foundation concrete on the column base, and open the anchor bolts buried in the foundation to the steel column base plate. Install the pillars through the holes for the anchor bolts. The holes for the anchor bolts drilled in the base plate are larger than the diameter of the anchor bolts so that the anchor bolts can pass easily.
Therefore, in most cases, when a pillar is installed, it deviates from the exact position of the pillar where the pillar must be installed. Therefore, the pillar must be moved to the exact pillar location where the pillar must be installed. There are the following methods for moving.

Hit the base plate in the direction you want to move with a large hammer.

, Pull it in the direction you want to move it with a buckle, lever block, chain block, etc.

And push it in the direction you want to move with a hydraulic jack or the like.

, Etc. As mentioned above, moving the pillar position requires a lot of effort,
It requires time, effort, etc., and depending on the situation at the site, a large hammer or other equipment may not be used. The present invention has been made to eliminate the drawbacks of the present invention and will be described with reference to the drawings. (Fig. 1) 2. The steel material is provided with a concave recess having a spherical diameter similar to that of the upper spherical part of a product capable of supporting and adjusting the load. (Fig. 2) 3. Assuming that the pillar to be built has been installed at the exact position of the pillar where the pillar must be installed, the load support and level adjustment that is currently installed on the foundation concrete is possible. The position of a product, etc. is indicated at the bottom of the base plate, and steel is attached to that position. (Fig. 3) 4. Insert the holes of the base plate into the anchor bolts (on the products that can support the load and adjust the level via the anchor bolts, etc.) and install the pillars. At this time, the upper part of the load-supporting and level-adjustable product, etc. engages with the spherical hollow part of the steel material attached to the base plate, so that the column is installed at the exact position of the column where the column must be installed . (FIG. 4)

Claims (1)

[Claims] (1) The upper part of a product or the like whose load can be supported and whose level can be adjusted (which is partly embedded in basic concrete and is generally called iron dumpling) is made spherical. (B) A spherical recess (hollow) with the same or larger diameter as the upper part of a product (load-supporting and level-adjustable product that is partially embedded in the foundation concrete and is commonly called iron dumpling) is made on steel. . (C) Assuming that the pillar has been installed at the exact position of the pillar where the pillar must be installed, a product that is currently installed (buried) in the foundation concrete and has a spherical top-load-supporting and level-adjustable product The position of such as (partially embedded in the foundation concrete and commonly called iron dumpling) is indicated below the base plate of the pillar, and steel is attached to that position. (D) When the pillar is fixed to the foundation with anchor bolts, the load can be supported and the level can be adjusted in the recess (dent) of the steel material attached to the lower part of the base plate of the pillar. (Referred to as) can be installed at the exact position of the pillar. Load supporting device with level adjustment function with steel column positioning function configured as above
