Embodiment 1

[0039] combine figure 1 , figure 2 , Figure 4~6 , a device for manufacturing air-entrained concrete blocks with holes and grooves by core pulling, including a mandrel 31, which is fixed inside the mold 20 through a fixed frame 30, and the installation position of the mandrel 31 is the same as that on the block 1 The positions of the inner hole and the groove are corresponding, and the fixed frame 30 is connected with the mold 20 through the positioning bracket 19, and the fixed frame 30 is provided with a locking pair for locking the mandrel 31.

[0040] Specifically, the fixed frame 30 is erected above the mold 20, the upper layer of the fixed frame 30 is fixed with an upper positioning backing plate 32, and the lower layer is fixed with a lower positioning backing plate 34, and an intermediate pressure is set between the corresponding pair of positioning backing plates. Tightening plate 33, the three form a group of locking pairs that fix a mandrel 31; each group of lock...

Embodiment 2

[0061] combine figure 1 , Figure 7 , Figure 4~6 , in this embodiment, specifically: in the direction of 4200mm of the embryo body 12, the L=600mm length of the block 1 is cut out from the transverse separation surface 14; The H=240mm height of the block 1; on the 600mm direction of the embryo body 12, the B=200mm width of the block 1 is cut out from the vertical vertical separation surface 15; in the 600mm direction of the embryo body 12, the On the side, a side groove 7 is prepared, and the cross-sectional size of the groove is a rectangle of 40mm×40mm and four corners R3mm.

[0062] The difference between this embodiment and embodiment 1 is:

[0063] Mandrel 31 selects the special-shaped thin-walled steel pipe of 80mm * 40mm;

[0064] Cutting can adopt the method in the patent of the applicant whose application number is 201310203569.3: "Method for making autoclaved aerated concrete components by cutting steel wires in mesh arrangement" to complete the cutting of the lon...

Embodiment 3

[0067] combine figure 1 , Figure 8 , in this embodiment, specifically: in the direction of 4200mm of the embryo body 12, the L=600mm length of the block 1 is cut out from the transverse separation surface 14; The B=200mm width of the block 1; in the direction of 600mm of the embryo body 12, the H=240mm height of the block 1 is cut out from the vertical vertical separation surface 15; the block 1 has an inner diameter of Φ25 perpendicular to the top surface hole.

[0068] The differences in this example are:

[0069] Mandrel 31 selects Φ25mm thin-walled steel pipe;

[0070] Cutting can adopt the method in the patent of the applicant whose application number is 201310203569.3: "Method for making autoclaved aerated concrete components by cutting steel wires in mesh arrangement" to complete the cutting of the longitudinal vertical separation surface 15;

[0071] The positioning position of the mandrel 31 needs to be recalculated, and the fixed frame 30 needs to be assembled o...

Abstract

The invention relates to a device and method for manufacturing aerated concrete blocks with holes and grooves in a core pulling mode, and belongs to the field of building energy conservation. A core rod (31) is fixed inside a mould (20) through a fixing frame (30), and inserting holes or locking pairs capable of locking the core rod (31) are formed in the fixing frame (30). The method for manufacturing the aerated concrete blocks comprises the following steps that (1) before or after grout is poured into the mould (20), the core rod (31) is inserted into a mould cavity of the mould (20) and is fixed; (2) after a blank is formed and before the blank is cut, the core rod (31) is pulled out; (3) according to the cutting scheme corresponding to the position of the core rod (31), cutting of the blank is completed, and a combination of block blanks stacked together is formed; (4) the combination of the block blanks is maintained and detached, and then the steamed and pressed aerated concrete blocks or foam concrete blocks with the inner holes and the grooves are formed. According to the device and method for manufacturing the aerated concrete blocks with the holes and the grooves in the core pulling mode, subsequent cutting processing is not needed, and the blocks are provided with the neat grooves or the inner holes before the maintenance of the block blanks.

Description

technical field [0001] A device and method for manufacturing aerated concrete blocks with holes and grooves by core pulling, belonging to the field of building energy conservation, in particular to a device and method for manufacturing aerated concrete blocks with holes and grooves. Background technique [0002] In the field of energy-saving buildings, most of the walls of the enclosure structure adopt autoclaved aerated concrete blocks GB11968-2006 and foam concrete blocks JG / T266-2011. Aerated concrete blocks are mostly cuboid components with length L=600mm, height H=240mm, width B=200mm (H and B also have other specifications). The outer surface of these components is a "plane" cut by the cutting wire (or ruler cutter) on the cutting machine. Get H, 4200mm (or 6000mm) cut to get B, and make the finished product after curing. [0003] In the wall masonry, it is necessary to set tie bars, so on the top (or bottom) of the block and along the length direction of the block, ...
