Referring to fig. 8, the method for manufacturing the cavity lattice wall prefabricated member includes steps S1 to S7.
And S1, paying off on the die table 6.
Here, the mold table 6 is generally horizontally disposed, and an auxiliary line of the area to be poured is drawn on the mold table 6 by a line drawing tool, so that a construction or production person can distinguish a positioning position for placing the side mold 7 or for facilitating alignment.
S2, arranging a side die 7 in the pay-off area of the die table 6, wherein the shape and the size defined by the side die 7 are matched with the shape and the size of the first wall 11 of the cavity lattice wall prefabricated member.
Wherein, side forms 7 fixed connection is on mould platform 6, through setting up side forms 7 on the unwrapping wire region, pours the material in side forms 7 and forms the wall body of required shape. For a rectangular wall, the number of the side forms 7 is generally 4, and the heights of the 4 side forms 7 can be the same or different. Because the plane of the wall 1 to be formed is parallel to the surface of the mould table 6 when the wall 1 is manufactured, the shape and the size surrounded by the side moulds 7 can be matched with the first wall 11 of the wall 1 to be formed. Of course, if the second wall 12 is located below the first wall 11 during the manufacturing process, the shape and size of the surrounding edge forms 7 can be matched with the second wall 12 of the wall 1 to be formed.
S3, a plurality of blocking devices 3 are disposed at positions corresponding to the plurality of cavities 2 of the cavity lattice wall preform. Wherein each blocking means 3 is a hollow housing having a certain spatial volume, as described with reference to the above embodiments.
When the blocking means 3 is provided, the blocking means 3 may be provided at a predetermined position, for example, by a support member, or the blocking means 3 may be fixed at a corresponding position of the structure such as the reinforcement cage 4.
S4, the first end of the die table 6 is lifted so that the die table 6 has a predetermined angle with the horizontal plane.
The first end part is the end part of the die table 6 where the feeding end is reserved during material distribution, and the lifting angle can be adjusted according to the difference of concrete proportion, workability and slump. Illustratively, the predetermined angle is 15 ° to 20 °.
And S5, distributing the material into the area surrounded by the side forms 7 from the first end part to form a first wall body.
Illustratively, the volume ratio of the material actually distributed in step S5 to the preset material required by the first wall is 105%. The preset material required by the first wall body is the volume of concrete required by the first wall body forming.
The process of above-mentioned cloth can adopt distributing machine 8 to accomplish, controls through the blowing speed and the inclination to distributing machine 8, can control the velocity of flow of material.
S6, placing the mold platform 6 flat, arranging a sealing device on the mold platform 6, wherein the shape and the size of the sealing device are matched with those of the second wall of the cavity lattice wall prefabricated member, and the height of the top surface of the sealing device is consistent with the thickness of the wall of the cavity lattice wall prefabricated member.
Here, the die table 6 is placed in a horizontal position. The edge banding device can be common channel steel, angle steel and can also be a magnetic side form. The edge banding device functions in accordance with the side forms 7 and can support and prevent concrete from flowing out sideways from the sides.
And S7, distributing the material into the area surrounded by the edge sealing device to a preset height to form a connecting wall body 13 and a second wall body 12.
Here, referring to fig. 9, when the material distribution (i.e., the second material distribution) in step S7 is performed, the first casting material 101 (i.e., the first wall 11) formed by the material distribution (i.e., the first material distribution) in step S5 is not solidified, and the second casting material 102 (i.e., the connecting wall 13 and the second wall 12) formed by the second material distribution may be connected with the first casting material 101 to form an integrally stressed wall structure.
The material in the above manufacturing method is, for example, concrete.
