Problems solved by technology
However, there are many problems in this method: there are discontinuous thermal insulation and cold bridge problems, which affect the external thermal insulation effect, and when there is a temperature difference in the corresponding room, it is easy to form condensation, which leads to mildew on the wall; the added outer panels not only Increasing the thickness of a single component also increases the self-weight of a single component; due to the increase in self-weight, it not only affects the flexibility of component disassembly, but also increases the difficulty and cost of production and transportation of components; in addition, the increase in self-weight of a single component, It also affects the site for on-site stacking, hoisting equipment, and management requirements
[0007] At present, no effective solutions have been proposed for the problems in the related technologies that the integrated insulation board cannot be prefabricated, on-site construction is required, the thickness of the insulation integrated board is thick and its weight is large, and the insulation is discontinuous.

Abstract
The invention relates to a PC heat-insulation integrated board and a production method thereof. The PC heat-insulation integrated board comprises a heat-insulation board, a plurality of anchoring elements, a wall board and a plurality of reinforcing steel bars, wherein the dry density of the heat-insulation board is 160-220 kg / m<3>, and the compressive strength of the heat-insulation board is greater than or equal to 0.30 MPa; the anchoring elements are mounted on the heat-insulation board in a penetrating manner; the wall board is fixedly arranged on the inner end surface of the heat-insulation board, and the distance between at least one edge of the heat-insulation board and the edge, corresponding to the edge of the heat-insulation board, of the wall board is 0-600 mm; and the reinforcing steel bars are fixedly arranged in the wall board. The PC heat-insulation integrated board has the advantages that the heat-insulation board and the wall board are integrally prefabricated, so that the working procedures of erecting a template and pasting the heat-insulation board on a construction site are reduced; the edge of the heat-insulation board protrudes out of the edge of the wall board, so that the external heat insulation is continuous, and a cold bridge problem is avoided; and the problem that the heat-insulation board falls off is avoided within a relatively long time after project completion.
Description
technical field [0001] The invention relates to the technical field of building prefabricated panels, in particular to a PC thermal insulation integrated panel and a production method. Background technique [0002] Precast concrete (PC) is usually used to prepare concrete building components, such as exterior wall panels, floor slabs, stairs, etc. The design and implementation process of PC exterior wall panel components are taken as an example to illustrate. The existing PC exterior wall panel member is a structural groove with a lower part that overlaps the upper and lower plates, and the outer side is protruding and the inner side is concave. Structural reinforcement is reserved, that is, a cast-in-place section needs to be set up between the upper PC exterior wall panel component and the lower PC exterior wall panel component through on-site formwork, so that the upper PC exterior wall panel component and the lower PC exterior wall panel component Component connection....
