JPS5853848Y2 - Fixing device at the bottom end of the column - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a column lower end fixing device that allows the position and height of the lower end of a column to be freely adjusted when fixing the lower end of a column in an attached building such as a balcony or entrance.

Conventionally, the lower ends of pillars of attached buildings such as balconies have been fixed using metal fittings that are fixed with anchor bolts buried in advance before the pillar is assembled, but in some cases, the lower ends of pillars attached to the upper structure, A positional or height deviation may occur between the anchor bolt and the anchor bolt that has been buried in advance, and in such a case, it is virtually impossible to correct the position or height using the conventional fixing method of pre-installing the anchor bolt.

In this invention, the position and height of the fixing device can be adjusted arbitrarily, and the lower end of the column can be fixed accurately and easily.In addition, by providing a protrusion on the base plate and pouring mortar, it is possible to easily fix the lower end of the column on the base concrete. The purpose of the present invention is to provide a fixing device for the lower end of a column that can be fixed to the lower end of a column.

An embodiment of the column lower end fixing device of the present invention will be described below with reference to the drawings.

The column lower end fixing device 1 of the present invention consists of a column holder 2 and a foundation fixing device 3.

The pillar holder 2 has a spiral tube 5a, which is a screw member 5, suspended from the lower surface of a U-shaped pillar holder 4 that opens upward and can hold the lower end surface of the pillar. A through hole 7 for inserting the hole 6 into the port 1 is bored in the hole 4.

The foundation fixture 3 is screwed onto the screw tube 5a by a base plate 9 having a protrusion 8 on its upper surface which is partially bent upward to protrude in the shape of a claw. A screw shaft 10a, which is a rotatable screw member 10, is set upright.

However, as shown in FIG. 2, a bolt hole 12 is provided in the lower end 11 of a column previously attached to an upper structure (not shown), and a bolt 6 is inserted through the column receiver 4. Pillar holder 4
After fixing the base plate 9 to the base concrete 1 while adjusting the screwing depth between the screw tube 5a and the screw shaft 10a.
The base plate 9 is placed on the base plate 9 while aligning the top end position and the mounting position, and then a decorative mortar 15 is laid on the top surface of the base plate 9 to hide a part of the base plate 9 and the screw members 5 and 10.

The protrusions 8 are in close contact with the mortar 15 to fix the base plate 9 to the base concrete 13.

The fixing device for the lower end of the column of the present invention, like the one on the diagonal, can be installed by aligning the position with the already installed column, so it eliminates the trouble of embedding the anchor bolt in the base concrete in advance, and also reduces the need for anchor bolts. It is possible to omit measurements for positioning the column, and the installation error when fixing the top end of the column can be absorbed, allowing for accurate and easy construction. The number of man-hours required for construction can be reduced, leading to significant labor savings.
