Embodiment 1

[0033] The manufacturing method of the ultra-wide heat-insulating cantilever plate of the present invention comprises the following steps:

[0034] Step 1.1, according to the blank body mold, blank body size and cutting capacity of the autoclaved aerated concrete component production line, make the blank body cutting plan of the ultra-wide heat-insulating cantilever slab; set the cutting steel wire system according to the blank body cutting plan; Determine the suspension position and method of the built-in steel mesh of the ultra-wide heat-insulating cantilever plate, and the minimum distance between the steel mesh and the cutting line is 2mm to 20mm;

[0035] Step 1.2, according to the hanging position and method of the reinforcement mesh, lay the reinforcement mesh into the mold;

[0036] In step 1.3, according to the determined steam-cured aerated concrete formula, the slurry preparation and pouring are respectively completed, and the development of the ultra-wide heat-insu...

Embodiment 2

[0054] Cut the size of the ultra-wide heat-insulating cantilever plate 12 to 2000mm*900mm*120mm. The upper part of the floor slab of the frame structure of the building is overlapped and poured as a whole with the floor slab. Compared with Example 1, the overlapping position is different, but the construction technology is similar.

Embodiment 3

[0056] Such as Figure 4 shown. Cut the size of the heat-insulating cantilever plate 12 to 2100mm*400mm*120mm. As the flange of the architectural appearance of the building, it is built to the bottom layer of the outer wall. This type of lap joint is completed through the masonry of the outer wall, and it is not necessary to adopt the annular steel bar 13 and the cast-in-place method.

Abstract

The invention relates to manufacturing and lap construction methods of ultra-wide autoclaved aerated concrete cantilever slabs, and belongs to the technical field of energy-saving building wall processes. The manufacturing method is characterized by including the steps: making a blank cutting plan on a blank mould and cutting capacity of an autoclaved aerated concrete member production line; setting a cutting wire system; laying a reinforcing mesh in the mould; completing slurry preparation and pouring, and performing blank growing and cutting; and maintaining, and making into finished products. The cantilever slabs are lapped on the upper surface and the lower surface of a frame beam (slab) pouring area, and is integrally poured with the frame beam (or slab) by the aid of annular reinforcing steel inserted into the pouring area. A wall structure formed by the cantilever slabs and the lap construction method thereof partitions a thermal bridge, has excellent thermal insulation performance and enough bearing mechanical property, is in a reasonable and reliable structural form, and is convenient to construct.

Description

technical field [0001] The invention discloses a method for manufacturing and lap jointing an autoclaved aerated concrete super-wide cantilevered slab, which belongs to the technical field of energy-saving building wall technology. In particular, it relates to a manufacturing and construction method of an ultra-wide heat-insulating cantilever plate. Background technique [0002] In the field of energy-saving building technology, lightweight cement-based blocks are widely used for walls of enclosure structures, such as steam-cured aerated concrete blocks GB11968-2006, and foam concrete blocks JG / T266-2011. Since the compressive strength, especially the tensile strength, of the lightweight cement-based block material is not high, the wall body cannot bear the load of anchoring the external unit of the air conditioner and the bay window. The current professional structural design of housing construction has to design reinforced concrete cantilevered slab structural components ...
