Embodiment Construction

[0010] from figure 1 It can be seen that the present invention has a panel 1 , a panel 2 and longitudinal and transverse ribs 3 , and a number of light-weight thermal insulation sandwich blocks are embedded in the bottom plate 1 , panel 2 and longitudinal and transverse ribs 3 at equal intervals. The bottom plate 1 is made of prestressed reinforced concrete, the face plate 2 is made of plain concrete with the same label as the bottom plate 1, the vertical and horizontal ribs 3 are made of thermal insulation concrete, and the sandwich block is a block of thermal insulation material. The production can be carried out on the long-line prestressed hollow slab pedestal, the prestressed steel bars are stretched, the shaping mold is raised, the floor concrete is poured for the first time, and the sandwich material blocks are equally spaced after troweling. Then pour the vertical and horizontal rib insulation concrete, the two poured panel concrete, vibrate and compact, and then smoot...

Abstract

The invention discloses a prestressed reinforced concrete sandwich heat insulating roof-panel which is characterized in that the reinforced concrete sandwich warming roof-panel comprises a reinforced bar concrete bottom board 1, a concrete face plate 2, a heat insulating concrete vertical and horizontal rib 3 and light heat insulating sandwich blocks 4 which are embedded in the reinforced bar concrete bottom board 1, the concrete face plate 2 and the heat insulating concrete vertical 3 at interval. The prestressed reinforced concrete sandwich heat insulating roof-panel is also characterized in that reinforced bars in the reinforced bar concrete bottom board 1 are prestressed reinforced bars 5. The heat insulating roof-panel integrates the bearing of the structure and the heat insulation and has the characteristics of light dead-weight, good structural performance, heat insulation and sound insulation, rapid and convenient construction, low cost and the like and is a new green energy-saving roof panel material with excellent cost performance.

Description

Technical field: [0001] The invention relates to a prestressed reinforced concrete sandwich insulation roof panel used for building roofs. Background technique: [0002] With the rapid growth of my country's economy, the crisis of energy shortage is also increasing. According to relevant statistics, in the total energy consumption, building energy consumption accounts for more than 20%. In order to ensure the sustainable development of my country's economy, construction Energy saving has become the top priority of my country's energy saving work. As the outer enclosure structure of a building, the roof is an important part of building energy conservation. At present, for buildings with flat roofs, the commonly used building energy-saving design is to build a thermal insulation layer on the roof panel to meet the design standards for building energy efficiency. The method of roof insulation and heat insulation houses, firstly, it needs to increase the construction process, a...
