Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides hollow panels (hereinafter simply referred to as panels) formed by extrusion molding of inorganic materials such as asbestos cement. inside formwork or inside,
The purpose of the present invention is to provide a method for constructing a concrete building, which can be used as an outside formwork and can simultaneously complete the exterior or interior of a building, or the interior and exterior, by integrating the panel with poured concrete. As proposed, panel fixing fastener A is attached to the building beam B.
A plurality of hollow parts 1a having a rectangular cross section are arranged at approximately equal intervals between the first step of attaching the engaging protrusions 1C provided at both ends, and forming a through cavity over the entire length in the vertical direction. a second step of erecting the extrusion-molded panel 1 with the mounting fittings a and b set in advance on the building beam B by connecting the mounting fittings a and b to the panel fixing fastener A;
After the engaging tool 2 is engaged with the engaging protrusions 1c of a large number of extrusion molded panels 1 built on the building beam B in the second step, one end of the spacing member 3 is attached to the engaging tool 2. After the inner formwork 4 is attached to the other end of the spacing member 3, the space between the side inner formwork 4 and the extrusion molded panel 1 erected in the second step is A method for constructing a concrete building using an extruded panel as a formwork, comprising a fourth step of pouring concrete.
This is related to.

Hereinafter, the present invention will be specifically explained with reference to FIGS. 1 to 3.

In these figures, 1 is a panel made of an inorganic material such as asbestos cement, and as shown in FIGS. 1 and 2, the panel 1 has a vertical hollow part 1a, and both horizontal edges A bilaterally symmetrical protrusion 1c is formed on the inner surface of the protrusion 1b.
A bent portion 1d for engaging the engagement metal is provided inside c. Further, a vertical projection 1e is provided protruding approximately at the center of the inside of the panel 1, and the projection 1e is designed to prevent the panel 1 from becoming an integral part of the concrete when concrete is poured, as will be described later. It helps to strengthen the system. a and b are connected to panel fixing fasteners A to be described later, and in order to erect panel 1 on building beam B (see Fig. 2), the panel 1 is attached in advance at a factory etc. as shown in Fig. 2. When forming an outer formwork with panel 1 using mounting brackets fixed with bolts etc., first attach the panel fixing fastener A to the building beam B that has been installed in advance.
Then, as shown in FIG. 2, the mounting brackets a, b are fixed by welding or the like to the tips of the fasteners A, and the panel 1 is attached to the mounting brackets a, b,
It is installed on the outside of the building beam B via the panel fixing fastener A. In this way, connect a large number of panels 1 to the outside of the building beam B with joints c between adjacent panels 1.
are provided, and packing materials 8 are fitted into the joints c and fixed in order to form an outer formwork with the panel 1. Next, after engaging the engagement tool 2 with the protrusion 1c on the inner surface of the adjacent panel 1, the engagement tool 2
Attach one end of the spacing member 3 to the spacer as shown in FIG. Next, after attaching the cone 6 to the other end of the spacing member 3, the inner formwork 4 is erected, and the horizontal flap material 7 is set so as to maintain a certain distance H from the outer formwork formed by the panel 1. The inner formwork 4 holding the is installed. Then, by pouring concrete 5 into the spaces of the inner and outer formwork and hardening it, a concrete building in which the outer formwork (panel 1) and the concrete 5 are integrated is constructed. After the concrete hardens, the inner formwork 4 is removed and a first
As shown in the figure, the concrete building is completed by filling with sealing material 9.

As described above, the present invention uses an extruded panel made of asbestos cement, etc., so it has excellent surface precision, is lightweight, and has high strength.
forms the exterior wall surface of the building as it is, so according to the present invention, not only the construction period of the building is significantly shortened, but also each panel (outer formwork) is attached to the building beam B by the fastener A for fixing the panel. Since it is fixed through the panel, there is no need to adjust the accuracy of the entrance and exit of the outer surface. Also, if the panel has an uneven surface pattern or tiles attached, it is possible to create any desired surface decoration, which is highly economical. The following practical effects can be mentioned.
