At least one of the first template 1 and the second template 2 is an insulation board provided with a template framework 5, and the template framework 5 is positioned in the pouring cavity. When the first template 1 or the second template 2 is an insulation board provided with a template framework 5, referring to fig. 1 and 3, the first template 1 is set as a conventional template which needs to be removed in the later period, the second template 2 is an insulation board provided with the template framework 5, and at the moment, the concrete member is only provided with the insulation board on one side corresponding to the second template 2; another case is that the first formwork 1 and the second formwork 2 are heat insulation boards provided with a formwork framework 5, see fig. 2 and 4, and at this time, the two sides of the concrete member are provided with heat insulation boards. The first template 1 and the second template 2 are respectively provided with connecting holes, the connecting holes are used for penetrating through connecting belts 6, the first template 1 and the second template 2 are connected through the binding of the connecting belts 6, the connecting belts 6 penetrate through the connecting holes, and the connecting belts 6 enable the first template 1, the supporting piece 4, the template framework 5 and the second template 2 to be relatively fixed. The connecting belt 6 plays a role of pulling and connecting the first template 1 and the second template 2, and is matched with the supporting piece 4 to enable the first template 1 and the second template 2 to be relatively fixed; the connecting belt 6 also plays a role in binding and fixing the heat-insulating plate and the corresponding template framework 5, so that the heat-insulating plate and the corresponding template framework 5 are relatively fixed. The connecting band 6 is typically a steel wire rope.
When the first template 1 is a conventional template which needs to be dismantled in the later period and the second template 2 is a heat-insulating plate provided with a template framework 5, the connecting belt 6 can firstly bind and fix the heat-insulating plate and the template framework 5 and then is connected with the first template 1 or is connected with the outer support structure 3 of the outer plate surface of the first template 1, and particularly, the heat-insulating plate is shown in fig. 1.

The heat preservation board is provided with a template framework 5, and the strength of the heat preservation board is improved by the template framework 5. The template framework 5 is fixed in an auxiliary mode, the heat-insulating plate can be fixed in an auxiliary mode, and therefore the outer supporting structure 3 with a simple structure and low strength requirement is arranged on the outer side of the first template 1 and/or the outer side of the second template 2, the pouring construction requirement can be met, and even the outer supporting structure 3 is not arranged. For example, referring to fig. 1 and 2, the outer plate surface of the first formwork 1 is provided with an outer support structure 3, and the outer support structure 3 includes transverse ribs, vertical ribs and diagonal braces. The first template 1 is a conventional template which needs to be removed in the later period, and when the outer supporting structure 3 is arranged on the outer plate surface of the first template 1, the other end of the connecting belt 6 for binding and fixing the heat-insulating plate and the template framework 5 can be fixed on the first template 1; in order to ensure the stability of the connecting belt 6, the other end of the connecting belt 6 for binding and fixing the heat-insulating board and the template framework 5 can also pass through the connecting hole of the first template 1 to be fixedly connected with the outer supporting structure 3. The formwork framework 5 is a prefabricated concrete pole piece of a section bar or a reinforcement, for example, the formwork framework 5 is a rectangular steel pipe, a round steel pipe, I-steel, angle steel or C-shaped steel.
When the pouring cavity between the inner plate surface of the first template 1 and the inner plate surface of the second template 2 is used for binding the structural steel bars 9 and pouring concrete, the structural steel bars 9 can be arranged without considering the reinforcing effect of the template skeleton 5 or the reinforcing effect of the template skeleton 5.

If the template skeleton 5 influences the arrangement of the structural steel bars 9 in the pouring cavity, through holes for arranging the structural steel bars 9 can be formed in the template skeleton 5, and the structural steel bars 9 can pass through the through holes of the template skeleton 5. In order to enable the template framework 5 to participate in the stress calculation of the structural steel bars 9, thereby controlling the manufacturing cost, the distance between the template framework 5 and the heat insulation board needs to be controlled. In order to facilitate the control of the distance between the template framework 5 and the inner plate surface of the heat insulation plate, a cushion block 8 is arranged between the template framework 5 and the inner plate surface of the heat insulation plate, and the cushion block 8 is generally precast concrete.

When the first template 1 and the second template 2 are heat-insulating plates provided with the template framework 5, two ends of the supporting piece 4 can be respectively in tight fit with the template framework 5. In order to avoid that the support 4 influences the construction of the poured concrete, the support 4 is preferably a bar, and the centre line of the support 4 is perpendicular to the plane corresponding to the first formwork 1. Since the plane corresponding to the first die plate 1 and the plane corresponding to the second die plate 2 are parallel to each other, the center line of the support 4 is also perpendicular to the plane corresponding to the second die plate 2.
The insulation board is used as a pouring template of a concrete member and an insulation structure of the concrete member, and is generally made of a light material, for example, the insulation board is an ALC board, a graphite modified cement-based insulation board, a perlite insulation board, a foam glass insulation board, a rock wool composite board, a polystyrene composite board, a graphite polystyrene composite board, a glass wool heat insulation composite board, an extruded polystyrene foam plastic or a ceramic sheet composite board. In order to improve the bonding strength of the insulation board and the concrete member, thereby improving the stability and durability of the insulation board attached to the concrete, the inner board surface of the insulation board is provided with concave-convex structures, concave holes or textures. The cast-in-place concrete is embedded into the concave-convex structure, concave holes and textures of the heat-insulating plate, so that the combination of the concrete member and the heat-insulating plate is more stable.
