Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1 to 4: the concrete foundation preformed hole mould comprises a mould main body 1 and a demoulding film 2; the mold main body 1 is in a quadrangular frustum pyramid shape with a large upper part and a small lower part, and the mold main body 1 comprises a mold shell 11 consisting of four mold side plates 111, four corner connecting columns 15, four middle connecting columns 12 and at least two cross-shaped support frames 13; the four corner connecting columns 15 are arranged in the vertical direction, and the four corner connecting columns 15 are respectively positioned at four corners of the inner side of the die shell 11 and are connected with the adjacent die side plates 111; the middle connecting columns 12 are arranged on the inner side of the die shell 11 in the vertical direction, and the four middle connecting columns 12 are respectively connected to the middle parts of the four die side plates 111; the cross support frames 13 are horizontally arranged in the die shell 11, the cross support frames 13 are connected with the four middle connecting columns 12, and the cross support frames 13 are arranged at intervals in the vertical direction; the demoulding film 2 is wrapped outside the mould main body 1.
When the concrete foundation preformed hole mold is used, as shown in fig. 5, the concrete foundation preformed hole mold is arranged at a proper position in the concrete foundation mold 7, and then concrete is poured between the preformed hole mold and the concrete foundation mold 7. After the concrete is solidified, the concrete is only adhered to the demoulding film 2 and is not adhered to the mould main body 1, so that the mould main body 1 can be integrally moved out of a concrete foundation to realize repeated use. The mould main body 1 is big end down, and further the mould main body 1 is convenient to move out of the concrete foundation. The die main body 1 is firm in structure, can avoid damage in the pouring and moving-out processes, and prolongs the service life of the die main body 1. The release film 2 is adhered to the concrete but may be peeled off.
The parts of the mould body 1 are conventionally made of wood and the connection between the parts can be by conventional nailing or bolting. The cross supports 13 are main members for improving the strength of the mold body 1, and the number thereof is preferably three, and one is provided at each of the upper, middle, and lower portions of the mold body 1.
When the mould main body 1 is moved out of the concrete foundation, a lifting device is required to be adopted for lifting, and a hook or a rope for lifting can be connected to the cross-shaped support frame 13. In order to further facilitate the hoisting, the concrete foundation preformed hole mould comprises a hoisting structure 3, and the hoisting structure 3 is positioned at the top of the mould main body 1 and is connected with two oppositely arranged middle connecting columns 12. The hoisting structure 3 is used for connecting a hook or a rope for hoisting, and can facilitate hoisting of the die main body 1.
The concrete foundation preformed hole mould is preferably connected with the concrete foundation mould 7 when in use so as to ensure the stability when in use. In order to be connected with the concrete foundation mold 7, the concrete foundation preformed hole mold comprises two parallel and horizontally arranged connecting cross rods 4, and the connecting cross rods 4 are positioned on the outer side of the top of the mold main body 1 and connected with the mold main body 1. As shown in fig. 5, the connecting rails 4 are laid on the concrete foundation mold 7, and the connecting rails 4 are connected to the concrete foundation mold 7 by a step-by-step process.
The connection of the connecting rails 4 to the mould body 1 is preferably as follows: the concrete foundation preformed hole die comprises U-shaped blocks 14 which are arranged in one-to-one correspondence with the corner connecting columns 15 and are provided with downward openings; the top of the corner connecting column 15 is exposed out of the die shell 11, the corner connecting column 15 is connected with the U-shaped block 14, and the connecting cross rod 4 is clamped in the U-shaped block 14. The connecting cross rod 4 can clamp the mould main body 1 after being connected with the concrete foundation mould 7, so that the mould main body 1 is fixed. The connecting rails 4 may be removed from the U-shaped blocks 14.
After the concrete is solidified, although the concrete does not adhere to the mold body 1, a certain clamping force is applied. The mould main body 1 is light in weight, the required lifting force is not large, in order to save cost, a crane can not be adopted to lift the mould main body 1, the lifting equipment is usually a self-made lifting frame, and a hand-operated hoist is arranged on the lifting frame. Since the lifting force of the lifting device is limited, it is sometimes difficult to separate the mold body 1 from the concrete. In order to facilitate demoulding, the concrete foundation preformed hole mould can be further provided with the following components: the concrete foundation preformed hole mould comprises two demoulding cross rods 5; the top of the middle connecting column 12 is exposed out of the die shell 11, and the exposed part is provided with a demoulding cross rod hole 121; the demoulding cross rod 5 penetrates through the two opposite middle connecting columns 12 from the demoulding cross rod hole 121, and the two ends of the demoulding cross rod 5 are in threaded connection with demoulding ejector rods 6 arranged in the vertical direction. During demoulding, a pressure reducing plate is laid on the solidified concrete, the demoulding ejector rod 6 is rotated to move downwards, and the demoulding ejector rod 6 is ejected on the pressure reducing plate, so that the mould main body 1 can be ejected. In operation, the four knockout pins 6 should rotate a small amount in sequence to avoid generating large tilting force.
Connecting horizontal pole 4 and drawing of patterns horizontal pole 5 are not used simultaneously to the two all can be dismantled, and in order to save the cost, connecting horizontal pole 4 and drawing of patterns horizontal pole 5 structure can be the same. Therefore, the connecting cross rod 4 and the demoulding cross rod 5 can be replaced and used mutually, so that mould parts are saved, and the cost is reduced.
