DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of erection of a pillar for constructing a handrail, a fence, and the like on a skeleton of a concrete structure.

[0002]

2. Description of the Related Art Conventionally, in a method of erecting a support for constructing a handrail or a fence, a concrete punching die for forming a support mounting hole is attached to a temporary frame for driving a concrete, and after the concrete is hardened, A method is known in which the base of the pillar is buried and fixed in the pillar mounting hole from which the punching die has been removed, and this method is used. There is a problem that it is not always the same, and an excavation operation for correcting the position of the pole mounting hole is required. In order to solve this problem, when constructing a handrail or fence, a pillar mounting hole is excavated at the position where the pillar of the skeleton is to be mounted, and the pillar is fixed to the pillar mounting hole when constructing handrails and fences in order to solve this problem There are also ways to do that. However, in this method, there is a problem that a pillar mounting hole for burying a large-diameter pillar has to be excavated, which takes a long time for the operation and causes heavy labor.

Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes a frame constituting a terrace, a stair, and the like of a concrete structure. An anchor bolt 2 having a base buried and fixed is planted at a standing position of a column of the frame 1. Numeral 3 is a cylindrical support column made of aluminum which is inserted into the upper end of the anchor bolt 2 protruding from the upper surface of the frame. The upper end is located at a position slightly lower than the height of the anchor bolt 2 in contact therewith. Further, the support column is fixed to the anchor bolt 2 by a fixing member 4, and the fixing member 4 for fixing the column support cylinder 3 to the anchor bolt 2 is inserted through the anchor bolt 2 through the center hole to support the column. Support cylinder 3
A washer 4a is in contact with the upper edge of the anchor bolt 2, and a nut 4b is screwed into the screw portion of the anchor bolt 2 with the seat surface in contact with the upper surface of the washer 4a. Reference numeral 5 denotes a column made of aluminum having a rectangular cross section which is inserted into a column supporting cylinder 3 fixed to the anchor bolt 2. The rattling between the support column 3 and the support column 3 is prevented from increasing. Reference numeral 6 denotes a fixing member for fixing the column 5 and the column supporting cylinder 3, and the fixing member 6 is a tapping screw 6a for screwing the column 5 and the column supporting cylinder 3 together.
Numeral 7 denotes a plastic concealing member for preventing the fixing member 6 for fixing the support column 3 and the support 5 from being exposed to the outside.

[0006] In order to construct such a support structure, first, an anchor bolt insertion hole having a fixed depth is drilled in the frame 1 at a position where each support 5 is erected. The depth of the anchor bolt insertion hole is such that a resin capsule described later can be inserted and stored. After drilling, blow off the crushed debris in the anchor bolt insertion hole with a blower, clean the dust adhering to the inner surface of the anchor bolt insertion hole with a brush, and further remove the dust in the anchor bolt insertion hole with a blower. Blow it away. After cleaning the dirt in the anchor bolt insertion hole in this way, the resin capsule is inserted into the anchor bolt insertion hole. Then, the anchor bolt 2 whose tip is cut obliquely at 45 degrees is driven into the anchor bolt insertion hole into which the resin capsule is inserted, to a predetermined depth while rotating. When the anchor bolt 2 is driven, the resin capsule is broken and separated inside, and the filled main agent and the curing agent are mixed to start a curing reaction. This curing reaction time is given according to the outside temperature, and when it reaches the mountable strength,
A column support cylinder 3 is inserted from the upper end of an anchor bolt 2 planted in the frame 1 and its lower edge is brought into contact with the upper surface of the frame 1, and a washer 4 a as a fixing member 4 is passed through the anchor bolt 2. It is brought into contact with the upper edge of the support cylinder 3.

Next, a nut 4b is screwed into the anchor bolt 2, the upper surface of the column support cylinder 3 is tightened with a washer 4a, and the column support cylinder 3 is tightened and fixed to the anchor bolt 2. The support column 5 is inserted into the support column 3 thus erected, and the base of the column 5 is screwed to the support column 3 with a screw 6 a as a fixing member 6 to fix the column 5. next,
The periphery of the base of the column 5 to which the screw 6a as the fixing member 6 is attached is covered with an annular concealing member 7 to conceal the screw 6a. In this way, when a large number of columns 5 are erected, lower rails 9 are attached between the side surfaces of the columns 5, and a number of handrails 10 are vertically arranged on the upper surface of the lower rails 9, and the handrails 1
The girder 10 is attached to the upper end of the 0, the both ends of the girder 10 are fixed between the side surfaces of the support 5, and a cap 12 is attached to the upper end of the support 5 to construct a handrail. In addition,
In the preferred embodiment, the fixing member 4 for fixing the support column 3 to the anchor bolt 2 includes a washer 4a and a nut 4a.
It is used and b, but not good even eliminating the washer 4a the strut support cylinder 3 as an inverted cup shape. In addition, the column 5 has a rectangular cross section, and the column 3 has a circular cross section. However, it is a matter of course that each column may have a rectangular cross section or a circular cross section.

[0008]

As is apparent from the above description, according to the present invention, an anchor bolt insertion hole is formed in a frame, and a resin capsule containing a main agent and a hardener separately housed in the anchor bolt insertion hole is inserted. Then, while rotating the anchor bolt, the tip of which is cut obliquely at 45 ° into the anchor bolt insertion hole, it is driven to a predetermined depth to break the resin capsule, and the main agent and the curing agent that are separated and filled inside are filled. The anchor bolt is implanted by mixing and hardening, and a pillar support cylinder having an outer diameter substantially equal to the inner diameter of the pillar is inserted into the upper end of the anchor bolt protruding from the upper surface of the frame, and this pillar support cylinder is anchor bolted. Top screw
By fixing to the anchor bolts with nuts screwed to the parts , a strong support core can be easily obtained, and furthermore, the support is inserted into the support support cylinder and the support base is inserted.
Part is fixed to the support column by a screw as a fixing member.
After, the base periphery of the column on which the above-mentioned screw is attached
By simply covering the screws with the annular concealing member to conceal the screws, it is possible to construct a high-strength support for the skeleton by a simple operation. In addition, if the fixing member for fixing the support column and the anchor bolt is made of a washer and a nut that is in contact with the upper end of the support column, the fixing work can be easily performed without using special tools or devices. It can be carried out. further,
By using a screw as the fixing member for fixing the support column and the support column, the fixing operation can be performed easily at low cost. In addition, by hiding the fixing member with the concealing member, the aesthetic appearance of the support can be improved, and the merchandise value can be enhanced. Therefore, the present invention greatly contributes to the development of the industry as a method for erecting a pillar and a pillar structure that solve the conventional problems.
