In such constructions, it is desirable to tighten the assembly together to prevent significant movement of the various sheets relative to each other. The decorative panel is sufficiently integrated with the structural panel to prevent accidental loss such as slipping of the decorative panel during transportation, temporary installation, or falling off due to wind suction. However, due to non-uniform temperature gradients across the cross-section of composite panels, the effects of temperature differences can cause structural or face panels to heat up if the connections between panels are not flexible or yield capable. This will cause cracks. If the elastic behavior of the sand inch wall panel is entirely synthetic, then
The possibility of cracking due to heat increases. The present invention provides a connecting mechanism to integrate the face panel, insulating panel, and structural panel to exhibit good performance, significantly reduce thermal cracking, and provide sufficient integrity to connect the insulating spring. and 1. A tight interface is maintained between the structural panels to prevent water from entering between them.

ている。The present invention provides a concrete sandwich panel and a method of making a concrete panel having insulating lamina sandwiched between a structural concrete channel and a concrete facing panel. A scheme of panel and insulating laminate integration is provided that minimizes the composite behavior of the panel under stresses that result in thermal cracking due to temperature differential effects. The six laminated structure maintains a tight interface between the insulation panel and the structural panel. In a preferred embodiment, both concrete panels have approximately 0.
It has been found that a C-tie connecting longitudinal reinforcing ronds with diameters from 47 cm to about 0.63 CII+ provides the desired balance between stiffness and non-synthetic performance.

決めしてこれを支持する。The method of the present invention relates to the assembly of panels in which the poured construction panel is moist but the C-tie is held in place by the abutting ends of the polymeric blocks of insulation. The abutment end is pressed against the C-tether by engaging the lower hook of the C-tether with a reinforcing rod in the lower panel. The reinforcing rods for the face panels are pressed into the upper curvature of the C-shaped lumber by wooden blocks supported by insulation, properly orienting and positioning the reinforcing rods in the upper hooks until the face panel solidifies. I support this.

．． Precut insulation 20 with a length of 2 m is superimposed on the structural panel 10 of soft wire concrete. next,
C-shaped tie 16, preferably made of stainless steel
is embedded in the structural panel as shown in the second diagram, and the cable wire 14t
It can be hung instead. The tether 16 has hooked ends in gripping relationship. The tether is positioned midway between the abutting ends between adjacent insulating materials 200 as shown in FIGS. 1 and 3. The insulation materials 20 are compressed together when supported in soft wire concrete with a tie inserted. Once the insulation has been applied and the tie is inserted and held upright, four additional reinforcing ronds are placed on top of the insulation and supported at intervals along with small pieces of wood 27 above the insulation. . The pieces of wood are sized to match by pressing reinforcing ronds onto the upper hooks of the ties. Horizontal tie material 30.3
2 is also connected to reinforcing rods to prevent the edges of the sand inch panel from cracking. A layer of approximately 5 cm of concrete is then poured over the insulation and the four reinforcing rods, ties and cross ties are wrapped and transported.

Using about 1.2 m of insulation, the ties 16 are spaced apart by about 1.2 cm.

。Because of the insulation separating face panel 25 from structural panel 10, a non-uniform temperature gradient exists across the sand inch panel. Therefore, the means for fastening the first and second panels (here face panel and structural panel) 1 together must accommodate thermal expansion of the panels to avoid thermal cracking. A C-shaped tie made of approximately 0.47 cm wire or approximately 0.63 cm wire is suitable for providing a non-composite action between the face panel and the structural panel while maintaining sufficient integrity of the panel. Therefore, the face panels will not be lost during handling or erection due to wind ingestion, etc.

It was used with a binder at m intervals. The structural panel cross-section was subjected to a breath stress of approximately 15.2 c+n with approximately 5.08 cm of urethane insulation and a face panel approximately 5.08 cm thick. The test used a panel approximately 8.37 m long. The panel was supported at two points approximately 1.6 m from each end. In the panel, holes were made through the face panel and the insulating material, and when a load was applied directly to the structural panel 1o, a load of k was applied and the deflection was measured.
