Description

Description: TECHNICAL FIELD The present invention relates to a column support member for building a reinforced concrete building.

[Related Art] In general, reinforced concrete buildings have economic advantages such as lower construction costs than steel frames, but they require more steps and lower labor productivity, and improvements have been demanded.

For this reason, even in conventional reinforced concrete buildings, the use of precast (PCa) members for columns, etc., has been used to shorten the construction period, but not only is the PCa member heavy, but also the joint between the column and beam There were problems such as the complexity of the part and the need for an experiment for confirming the integrity.

[Problems to be Solved by the Invention] The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to use a conventional reinforced concrete construction method while maintaining a central portion of a column. Construction of a reinforced concrete building that allows two or more layers of column and beam reinforcement to be constructed at the same time by connecting two or more layers of column support members so that they can be connected, thereby saving labor and shortening the process. An object of the present invention is to provide a column support member.

[Means for Solving the Problems] A column supporting member for building a reinforced concrete building according to the present invention is a column supporting member on a lower floor which is embedded in a central portion of a column and is buried in column concrete which is cast in place. In the construction pillar support member configured to attach a pillar member to the upper part of the building, and to connect the pillar support member on the upper floor via the pillar member,
The support member is extended so as to penetrate a beam line of a beam to be joined on the column, a connection plate is attached to an upper end thereof, and a lower end column support member is connected to a lower end of the column support member. A pillar substrate for connecting to a plate is provided. Further, the present invention is characterized in that the column supporting member is configured by filling concrete in a steel pipe.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

1 and 2, reference numeral 1 denotes a column supporting member, which is set at the center of a column A between the floor slab 2 and the beam 3.

As shown in FIGS. 3 and 3A, the column supporting member 1 is formed by filling a steel pipe 1a with a concrete 1b inside a spiral pipe having a diameter of about 200 mm or the like. This column support member 1 is buried and killed in the column concrete cast in place.

A pillar substrate 1c is attached to the lower end of the pillar support member 1. A recess 1d is formed at the lower end of the pillar support member 1 and at the center of the pillar substrate 1c so that the head of a fixing bolt described later can be accommodated therein. (See also FIG. 3B) A column member 4 is integrally inserted above the column supporting member 1. The support member 4 is made of a large-diameter steel bar or an iron pipe.

The beam 3a of the beam 3 is set on the support member 4. In order to receive the beam 3a, for example, a beam bar 4a shown by a virtual line may be provided.

As shown in FIGS. 4 (A) and 4 (B), a connection plate 5 for connecting to the pillar substrate 1c of the pillar support member 1 on the upper floor is attached to the upper end of the pillar member 4. . The connection plate 5 is attached and fixed to the upper end of the support member 4 by a fixing tool 5a such as a fixing bolt. A connection bolt 5b is implanted at a corner of the upper surface of the connection plate 5.

6 is a column, 7 is a girder PCa member, and 8 is a PCa balcony.

Next, a construction method using the column support member 1 will be described.

First, as shown in FIG. 5, the column supporting member 1 is set on the column supporting member 1 'on the lower floor. In addition, when there is no pillar support member 1 'below, it is set on a floor slab.

When the column supporting member 1 is set, as shown in FIG. 6, a column bar 6 is arranged around the column supporting member 1 and
A beam bar 3a is erected above the column supporting member 1. After or simultaneously with the installation of the beam bars 3a, the half-PCa slab 2 is installed.
The semi-PCa slab 2 is installed by being supported by a support member 7 ′ buried in a door boundary wall or a beam formwork (not shown). The slab may be an all-PCa slab or a cast-in-place slab in addition to the half-PCa slab.

Simultaneously with or before or after the reinforcement of the column reinforcement 6 or the installation of the beam reinforcement 3a, as shown in FIG. 4, it is connected to the upper end of the support member 4 above the column support member 1 by the fixture 5a. The plate 5 is mounted, and the column support member 1 "on the upper floor is set thereon as shown in Fig. 7. The column support member 1" is set as shown in Fig. 3. A pillar substrate 1c provided at the base of the pillar support member 1 ″ on the connection plate 5 of the support member 1
Is carried out and tightened and fixed to the connection bolt 5b with a nut.

When the column supporting member 1 "is connected and set on the upper floor, a column bar is arranged around the column supporting member 1", and a beam bar is also set on the column supporting member 1 ". Assemble the frame and cast concrete in place.

[Effects of the Invention] (1) The steel pipe is filled with concrete and the column members are extended in the upper axial direction, so that the column and beam reinforcements and the girder PCa are simultaneously installed on two or more floors. The members can be erected, thereby saving labor and shortening the process.

(2) Since the conventional reinforced concrete method is used, economic advantages of the conventional method can be utilized.
