DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stone pillar and a stone panel in which a stone pillar and a stone panel are preliminarily formed by industrial production, and the stone pillar and the stone panel are assembled on site to easily construct a building body made of a stone material. The present invention relates to panels and their formless construction methods.

[0002]

2. Description of the Related Art The present applicant has devised a construction method for assembling a stone panel without using a form when constructing a building body made of this kind of stone material, which has been disclosed in Japanese Patent Application Laid-Open No. 5-25871. Filed.

[0003] That is, a reinforcing bar is assembled on the upper surface of a concrete foundation, and first-stage block-shaped processed stones are installed on both sides of the reinforcing bars at predetermined intervals so as to face each other. The concrete and the processed stone are integrated by being driven to near the upper end between them, and thereafter, the processed stone is stacked in multiple stages by the same procedure to integrate the concrete and the processed stone.

[0004]

However, according to the method of constructing a stone panel, a reinforcing bar must first be assembled on the upper surface of the concrete foundation at the construction site, and the first-stage processed plate stone is installed in an opposed manner. In the meantime, after concrete is poured in, the processed stones are repeatedly stacked in the same procedure in multiple stages, so not only this work requires much labor but also construction technology is required, and concrete is hardened. Since the work of assembling floors and ceilings cannot be performed until then, there remains a problem that the construction period cannot be shortened and the construction cost cannot be reduced.

Therefore, the present invention has been made to solve the above-mentioned problems, and uses a steel pillar for a pillar or a stone panel and fills it with lightweight concrete to increase the strength and reduce the weight. To provide a stone pillar, a stone panel, and a formwork-free construction method thereof that can be easily assembled at a construction site and can realize simplification of work, shortening of a construction period, and reduction of construction cost even to the fullest. The purpose is to:

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, a stone pillar according to the present invention is formed by inserting a steel frame in a vertical direction into a hollow cylindrical decorative stone material having a hollow inside and open at both upper and lower ends, and foaming. Filled with a binder such as concrete,
The steel frame has a lower end protruding from the lower end surface of the decorative stone material, and further has a base plate provided with an anchor bolt insertion hole at the lower end thereof.

In the stone panel of the present invention, a pair of thin plate-shaped decorative stones are provided opposite to each other at an appropriate distance, and a steel frame is vertically arranged between the two decorative stones, and a binder, which is lightweight concrete, is filled. The steel frame has a lower end protruding from the lower end surface of the decorative stone material, and further has a base plate having an anchor bolt insertion hole at the lower end thereof.

[0008] Further, according to the method for forming a stone pillar and a stone panel without a formwork, the stone pillar and the stone panel are erected at predetermined positions on the upper surface of a concrete foundation on which a plurality of anchor bolts are planted, and lower ends of the stone pillar and the stone panel are arranged. The insertion hole provided in the base plate is inserted through an anchor bolt, and then the nut is fastened to the anchor bolt, and thereafter, a plurality of stone pillars or stone panels are connected to the upper surface of the concrete foundation in the same procedure to be erected. is there.

[0009]

According to the present invention, a steel frame is inserted vertically into a hollow cylindrical decorative stone having open upper and lower end surfaces or between a pair of thin plate decorative stones, and a lightweight concrete binder is filled. With this configuration, a stone pillar or a stone panel can be factory-produced, and the strength can be increased by using a steel frame, and the weight can be reduced by filling with lightweight concrete. Also, at the construction site, the stone pillars and stone panels are erected on the upper surface of the concrete foundation, and the pillars and stone panels are fixed only by inserting the insertion holes provided in the base plate through the anchor bolts and tightening the nuts. A plurality of stone pillars and stone panels are erected on the upper surface of the concrete foundation without using a formwork. This not only makes assembly easier, but also shortens the construction period,
Moreover, the construction cost can be reduced.
