Problems solved by technology

Although this type of wall insulation system achieves the purpose of thermal insulation and the same lifespan as the wall structure, because the inner and outer concrete walls are mainly tied by the abdominal wires in the steel grid frame, a large number of abdominal wires are needed, which causes the wall The heat loss of the body insulation system reduces the thermal insulation performance and causes a waste of energy. As my country's building energy-saving design standards gradually approach the energy-saving rate of 75%, and even increase to higher requirements, this type of reinforced grid insulation board The wall insulation system of cast-in-place concrete on both sides is becoming more and more difficult to meet the new requirements of building energy saving

Embodiment 1

[0049] Such as Figure 1-Figure 3 As shown, a composite insulation board cast-in-situ concrete sandwich wall structure is composed of insulation board 1, fireproof layer 2, inner concrete structure layer 3, outer concrete protection layer 4 and tie positioning parts 5. The inner concrete structure layer 3 is used as the load-bearing structure of the building. The insulation board 1, the fireproof layer 2 and the outer concrete protection layer 4 together constitute the non-load-bearing insulation structure of the building. Reliable connection.

[0050] In order to increase the tie between the insulation board 1, the outer concrete protection layer 4 and the inner concrete structure layer 3, the tie positioning part 5 is installed after the insulation board 1 is arranged in the construction process, and they are tied together by the tie positioner 5 , tie locator 5 is made up of tie rod 12, locator piece 13 and concrete block 14, adopts reinforced composite concrete block, has...

Embodiment 2

[0053] As shown in Figure 4-7, a composite insulation board cast-in-place concrete sandwich wall structure is composed of insulation board 1, fireproof layer 2, inner concrete structure layer 3, outer concrete protection layer 4 and tie positioning parts 5, The inner concrete structure layer 3 is used as the load-bearing structure of the building. The insulation board 1, the fireproof layer 2 and the outer concrete protection layer 4 together constitute the non-load-bearing insulation structure of the building. Reliable connection.

[0054] In order to increase the tie between the insulation board 1, the outer concrete protection layer 4 and the inner concrete structure layer 3, they are tied together through the tie locating piece 5, and the diameter of the steel bar used for the tie locating piece 5 is not less than 6mm. According to the height of the building and The thickness of the outer concrete protective layer 4, the tie anchors 5 extending into the inner concrete stru...

Abstract

The invention relates to the technical field of building structure heat-insulation system devices. A composite heat-insulation plate cast-in-place concrete sandwiched wall structure is characterized by comprising a bearing structure layer, a non-bearing structure layer and a drawknot locating part for connecting the bearing structure layer with the non-bearing structure layer. The drawknot locating part comprises a drawknot rod and locating pieces arranged at at least one end of the drawknot rod. Synchronous construction of wall heat insulation and a building bearing structure is achieved, construction processes are reduced, the goal of the same service life of heat insulation and a building wall is achieved, the 75% and even higher requirements of the energy-saving design standard are met, and the composite heat-insulation plate cast-in-place concrete sandwiched wall structure has the advantages of being good in heat insulation effect, free of hidden fire danger, high in construction quality and safe and durable in structure.

Description

technical field [0001] The invention relates to the technical field of thermal insulation system devices for building structures, in particular to a composite thermal insulation board cast-in-situ concrete sandwich wall structure. Background technique [0002] With the continuous deepening of my country's wall material innovation and building energy-saving work, a new structural system with the same life span as thermal insulation and building walls has been developed rapidly. Since the shear wall structure and frame-shear wall structure engineering mainly composed of cast-in-place concrete account for a large proportion of new buildings; there are also a variety of wall insulation structures with cast-in-place concrete on both sides of the reinforced grid insulation board. The inner and outer concrete walls are connected by a steel grid that penetrates the insulation board. Although this type of wall insulation system achieves the purpose of thermal insulation and the same...
