Detailed Description

In order to facilitate understanding of the technical solutions of the present invention, the following detailed description is made with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 1 and 2, the present embodiment provides a prefabricated part mold set including: the forming die comprises two forming dies 1 and a plurality of demolding mechanisms 2, wherein the forming dies 1 are arranged at intervals along the transverse direction, and the demolding mechanisms 2 are arranged between two adjacent forming dies 1 at intervals along the longitudinal direction (the transverse direction is defined as the width direction of the forming dies 1, and the longitudinal direction is defined as the length direction of the forming dies 1). Of course, when the prefabricated member mold set has three or more molding molds 1, the demolding mechanism 2 may be arranged between adjacent two molding molds 1. The forming die 1 comprises a bottom die plate 11 and side die plates 12 which are vertically arranged on two sides of the bottom die plate 11 and connected with the demolding mechanism 2, the demolding mechanism 2 can enable the side die plates 12 to move towards the direction far away from the prefabricated part 3 in a self-adaptive mode when the prefabricated part 3 is lifted and demolded, demolding gaps are formed between the prefabricated part 3 and the side die plates 12, and therefore the prefabricated part 3 can be conveniently detached.

In the structure, because in the production process, concrete materials are distributed in the forming die 1, in the concrete setting process, the volume of concrete is increased, the side die plates are inclined towards the outer side of the die cavity under the pressure of the concrete, and when the die is demolded, large extrusion force is generated between the oppositely arranged side die plates on the prefabricated part, so that the friction force between the side die plates and the prefabricated part is large, the demolding is not easy to occur, the demolding is repeatedly lifted, internal damage and surface irregular cracks are easily caused to a product, and the product quality is seriously influenced. Therefore, in the embodiment, after the production is finished, the demolding mechanism 2 arranged between two adjacent molding dies 1 automatically moves the side mold plates in the direction away from the prefabricated part 3 without the assistance of other power devices when the prefabricated part 3 is lifted for demolding, so that the prefabricated part 3 is separated from the side mold plates 12, and the prefabricated part 3 is convenient to be demolded.

In addition, the prefabricated part 3 needs to be steam-cured during the production process to improve the condensation rate of the prefabricated part 3 and the structural strength after condensation. In the structure, the forming die 1 is a U-shaped die formed by enclosing a bottom die plate 11 and two side die plates 12 vertically arranged on two sides of the bottom die plate 11. The forming die 1 can be directly fixed on the hard bearing surface, the concrete retaining wall is arranged around the forming die 1, the forming die 1 is surrounded to form the steam curing pool, the forming die 1 is arranged in the steam curing pool at intervals along the transverse direction, a plurality of prefabricated parts 3 can be produced in the one-step production process, the forming die 1 is prevented from being lifted in a workshop, the forming die 1 is prevented from being damaged, and the safety of workers in the production process is improved.

As shown in fig. 9, the forming die 1 in this embodiment is used for forming the variable cross-section square pile, that is, the prefabricated member is the variable cross-section square pile (the variable cross-section square pile is defined as the square pile with the cross-sectional area size varying in the axial direction), so that the forming die 1 is formed with the coarse die cavities and the fine die cavities alternately distributed in the longitudinal direction.

Specifically, the forming die 1 forms the variable-section square pile by forming the prefabricated part 3 into the necking section 31 by arranging the bottom die plate 11 and/or the side die plate 12 at intervals. Compared with the traditional square pile, namely the square pile with smooth periphery, the variable cross-section square pile has the necking section 31, and the friction force between the variable cross-section square pile and the soil layer is larger, so that the anti-pulling and anti-pressure performance of the variable cross-section square pile is stronger than that of the traditional square pile. Preferably, the protrusions are connected to the bottom form 11 and/or the side forms 12 by connectors, so as to increase the versatility of the molding die 1, and may be integrally molded when the bottom form 11 and/or the side forms 12 are manufactured.

Further, the demolding mechanism 2 in this embodiment includes a trapezoidal carrier 21 standing between two adjacent molding dies, and a slider 22 slidably engaged with an inclined surface of the trapezoidal carrier 21; wherein, in the lifting demoulding direction, the transverse width of the trapezoid bearing body 21 is gradually reduced; the sideforms 12 and the slider 22 are integrally formed, or the slider 22 and the sideforms 12 are detachably connected.

In the above structure, since, in the initial state, there is a large frictional force between the prefabricated units 3 and the sideforms 12, thus, when the prefabricated unit 3 is lifted and moved upward, the sideforms 12 are frictionally moved upward together with the prefabricated unit 3, and because the sideform 12 and the slider 22 are integrally formed or detachably connected, and the slider 22 is slidably engaged with the inclined surface of the trapezoidal carrier 21, the sliding body 22 will generate a component force upward along the inclined surface of the trapezoidal carrier 21, so as to urge the sliding body 22 and the sideform 12 to move obliquely upward along the inclined surface of the trapezoidal carrier 21, at this time, the pressing force between the sideform 12 and the prefabricated component 3 is gradually reduced, when the sideforms 12 move together with the slider 22 to a certain extent, the deformation of the sideforms 12 disappears, the sideforms 12 are completely separated from the prefabricated unit 3, and the prefabricated unit 3 can be easily lifted out of the cavity.

Furthermore, as shown in fig. 3, in order to realize the sliding engagement between the slider 22 and the trapezoid carrier 21, in the present embodiment, at least one dovetail groove 222 is provided on the inner side surface of the slider 22, and a dovetail block 211 corresponding to the dovetail groove 222 of the slider 22 is provided on the inclined surface of the trapezoid carrier 21. Wherein, the axes of the dovetail groove 222 and the dovetail block 211 are parallel to the contour generatrix of the inclined surface of the trapezoid carrier 21.

With the above structure, it is ensured that the slider 22 can slide only along the inclined surface of the trapezoidal carrier 21. Of course, at least one dovetail block 211 may be provided on the inner surface of slider 22, and dovetail grooves 222 corresponding to dovetail blocks 211 of slider 22 may be provided on the inclined surface of trapezoidal carrier 21.

More specifically, the dynamic friction factor μ between the inclined surface of the trapezoidal carrier 21 and the slider 22 is smaller than the tangent value of the inclined surface angle θ of the trapezoidal carrier 21, i.e., μ < tan θ.

In the above structure, if μ is greater than or equal to tan θ, after the prefabricated part 3 is separated from the side mold plates 12, the side mold plates 12 and the sliding body 22 are in a friction self-locking state, the state when the prefabricated part 3 is lifted away can be maintained, at this time, the side mold plates 12 and the sliding body 22 stay on the inclined surface of the trapezoidal carrier 21 together, at this time, the side mold plates 12 are in a demolding state, and the side mold plates 12 and the sliding body 22 need to be manually reset together during the next production, so as to ensure that the side mold plates 12 can abut against the bottom mold plate 11, otherwise, the next production cannot be performed, and manual operation cannot be ensured, because the side mold plates 12 and the sliding body 22 are inconvenient in weight, operation is performed, and meanwhile, safety cannot be. Therefore, in order to enable the sliding body 22 and the side mold plates 12 to be automatically reset after the prefabricated part 3 is hung away, by adopting the structure, the side mold plates 12 and the sliding body 22 can slide down along the inclined surfaces of the trapezoidal carrier 21 under the action of self gravity to reset again, so that the side mold plates 12 are abutted with the bottom mold plate 11 and are restored to the mold closing state, and the production efficiency is improved.

Furthermore, due to the heavy weight of the side mold plates 12 and the slider 22, when the slider 22 of the side mold plates 12 slides down along the inclined plane of the trapezoidal carrier 21 under the action of its own gravity, impact force may be generated on the hard bearing surface and counter impact force may be generated on the trapezoidal carrier and the slider 22, which may cause the displacement of the bottom mold plate 11, the trapezoidal carrier 21 and the slider 22, thereby causing damage to the equipment. Therefore, an elastic buffer 223 is provided at the bottom of slider 22 and/or the bottom edge of trapezoidal carrier 21 to slow down the sliding speed of slider 22 and sideform 12, and reduce the impact force and counter impact force. In this embodiment, a resilient bumper 223 is provided at the bottom edge of the trapezoidal carrier 21. Preferably, the elastic buffer 223 is a buffer spring.

In addition, in order to prevent the leakage of the concrete mortar after the distribution from the joint gap between the side form 12 and the bottom form 11, which results in the waste of raw materials and the unevenness of the surface of the prefabricated part, the sealing tape 13 is filled in the gap between the side form 12 and the bottom form 11. In order to prevent the side mold plate 12 from colliding with the bottom mold plate 11 when the slider 22 slides down the movable side mold plate 12 automatically, and thus the side mold plate 12 and the bottom mold plate 11 are damaged, it is preferable that the sealing strip 13 is an elastic sealing strip.

Example 2

In this embodiment, the same portions as those in embodiment 1 are given the same reference numerals, and the same description is omitted.

As shown in fig. 4, 5 and 6, the demolding mechanism 2 in the present embodiment includes a trapezoidal carrier 21 disposed between two adjacent molding dies, and a slider 22 slidably engaged on an inclined surface of the trapezoidal carrier 21; wherein, slider 22 and side form 12 slip joint.

In the above structure, when the prefabricated part 3 is lifted and moved upwards, the slide body 22 is slidably engaged with the sideform 12, so that the sideform 12 is moved upwards together with the prefabricated part 3 until the sideform 12 is relatively engaged with the slide body 22, at this time, if the friction force between the sideform 12 and the prefabricated part 3 is small, the sideform 12 can be directly separated from the prefabricated part 3 when the prefabricated part 3 is lifted continuously, and if the sideform 12 cannot be separated from the prefabricated part 3, the prefabricated part 3 is lifted continuously, at this time, the sideform 12 and the slide body 22 are moved upwards obliquely along the inclined surface of the trapezoidal carrier 21 together under the action of the friction force, so that the sideform 12 is separated from the prefabricated part 3 gradually. The principle of the slider 22 moving obliquely upward along the inclined surface of the trapezoidal carrier 21 is described in embodiment 1 and will not be described in detail.

Further, as shown in fig. 7, in order to realize the sliding engagement between the sideform 12 and the slider 22, in the present embodiment, at least one T-shaped block 121 is disposed on the outer side surface of the sideform 12, and a T-shaped groove 221 corresponding to the T-shaped block 121 of the sideform 12 is disposed on the outer side surface of the slider 22. In the present embodiment, the outer side surface of the slider 22 and the outer side surface of the sideform 12 are perpendicular or substantially perpendicular to the bottom form 11. In addition, the axes of the T-shaped block 121 and the T-shaped groove 221 are parallel to the contour generatrix of the outer side surface of the sliding body 22.

With the above structure, it is ensured that the sideform 12 can move only up and down along the outer side surface of the slider 22. Of course, at least one T-shaped groove 221 may be provided on the outer side surface of the sideform 12, and the T-shaped block 121 corresponding to the T-shaped groove 221 of the sideform 12 may be provided on the outer side surface of the slider 22.

Furthermore, as shown in fig. 8, the sliding body 22 is provided with a stop 2211 at the top of the T-shaped groove 221, and a stop 1211 at the bottom of the T-shaped block 121 to prevent the sideform 12 from separating from the sliding body 22 after the sideform 12 moves upward together with the prefabricated unit 3.

When the sideforms 12 move upward together with the prefabricated units 3, without the above structure, after the sideforms 12 are separated from the sliders 22, the prefabricated units 3 are separated from the sideforms 12, but the sideforms 12 may directly fall down, and may turn over due to lack of other limit positions, and the sideforms 12 have a heavy weight, which may cause great damage to the bottom forms 11 and the sliders 22. In addition, in the next production, the T-shaped block 121 of the sideform 12 needs to be fitted into the T-shaped groove 221 of the slider 22 again, and the production efficiency is lowered. Therefore, with the above configuration, the sideform 12 can be directly locked to the slider 22 after sliding a certain distance, and the sideform 12 can be prevented from being separated from the slider 22. And after the sideforms 12 are separated from the prefabricated part 3, the sideforms 12 can be dropped by their own weight to return to the original mold-clamping state. In order to prevent the side formworks 12 from causing great damage to the bottom formwork 11 in the falling process, elastic sealing strips are filled in gaps between the side formworks 12 and the bottom formwork 11, and concrete mortar leakage can be reduced when the elastic sealing strips are used for distributing materials.

The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is defined by the scope defined by the claims, and a plurality of modifications and decorations made by those skilled in the art without departing from the spirit and scope of the present invention should also be regarded as the protection scope of the present invention.
