In the prior art, an assembly type building is formed by splicing and pouring a plurality of prefabricated components on a construction site. To accomplish splicing and casting of two or more prefabricated units, the prefabricated units are usually provided with several prepared holes near their edges. The preformed hole is generally arranged in the thickness direction of the prefabricated part in a penetrating mode, and is used for being matched with the screw rod to fix the prefabricated part and the support, and then two or more prefabricated parts fixedly arranged at preset positions are fixed in a cast-in-place mode.
However, the size and dimension of the prefabricated components, and the size, position and shape of the prepared holes can be changed according to the change of the assembled building style; at this time, the size and the dimension of the hole forming die for processing the prepared hole also need to be changed, so that the framework of the hole forming die also needs to be adjusted adaptively. The framework made of plastic steel or glass fiber reinforced plastic generally needs injection molding, and independent die sinking is needed when adjusting the size and the shape of the framework, so that the cost is high, and the framework is not suitable for processing small-batch and multi-size pore-forming dies.
To solve the above problems, the present embodiment provides a pore-forming module including a skeleton and a flexible layer 200. The bottom end of the backbone is provided with a connecting part, and the connecting part is used for fixedly mounting the pore-forming module on the bottom die; the flexible layer 200 is formed on the skeleton and wraps the skeleton except for the connection portion.
In the present embodiment, the frame is made of a metal material, such as stainless steel, aluminum alloy, titanium alloy, or the like; therefore, the framework of the embodiment can be manufactured in a turning mode, additional die sinking is not needed, and cost can be saved to a large extent. In addition, the reinforcing structure provided on the skeleton can improve the connection strength between the skeleton and the flexible layer 200, thereby improving the pullout resistance of the entire pore-forming module.
Example 1
Referring to FIG. 1, in this embodiment, the pore-forming module includes a backbone and a flexible layer 200. The skeleton comprises a backbone and a plurality of reinforcing structures arranged on the backbone, the backbone can be made of metal materials, so that turning machining is facilitated, a connecting portion 131 is arranged at the bottom end of the backbone, the connecting portion 131 and the backbone can be of an integrated structure, and external threads can be formed in the connecting portion 131 and used for being matched with a mounting hole formed in a bottom die and provided with internal threads.
The flexible layer 200 is formed on the skeleton by glue injection, and the skeleton is wrapped except for the connecting part, that is, the connecting part at the bottom end of the skeleton is exposed out of the bottom end of the flexible layer 200. The flexible layer 200 may be made of a gel material, particularly a silica gel material, or a rubber material, and the flexible layer 200 may be formed by injecting glue and wrapped on the skeleton 210; in addition, the flexible layer can also be made of soft plastic materials, such as TPU, TPE, TPR, TPV, CPE.
In this embodiment, the reinforcing structure may be a reinforcing ring 131, and the reinforcing ring 131 may be connected to the stem by welding. More specifically, the reinforcement ring 131 may be a metal washer. When the framework is machined, the metal gasket can be sleeved on the backbone and placed at a designed position, and then the inner ring of the metal gasket is fixedly connected with the backbone in a welding mode.
Still further, in the present embodiment, the reinforcement ring 131 may be provided in several numbers, for example, 1, 2, 3, or more. When the number of the reinforcement rings 131 is 3 or more, 3 or more reinforcement rings 131 may be uniformly distributed along the axis of the stem.
Of course, 3 or more reinforcing rings 131 may be unevenly distributed, and particularly, when the flexible layer 200 has a truncated cone shape with a large top and a small bottom, the distance between adjacent reinforcing rings 131 gradually increases along the axis of the stem in the direction from the end close to the connecting portion to the end far from the connecting portion. Therefore, the density of the reinforcing rings 131 on the axis of the backbone is positively correlated with the amount of the sizing material used for the flexible layer, so that the overall strength of the hole forming die is improved.
In addition, along the axis of the backbone, the outer diameter of the reinforcement ring 131 gradually decreases from the end close to the connecting portion to the end far from the connecting portion, so as to fit the flexible layer 200 in the shape of a truncated cone with a small top and a large bottom.
In this embodiment, the flexible layer 200 may be a circular truncated cone structure, and the outer diameter of the flexible layer 200 gradually increases from the top end to the bottom end, that is, the circular truncated cone shape with the above-mentioned "big top and small bottom". In the forming die, the pore-forming module is fixed on the die table, and one end with the smaller diameter of the pore-forming module is arranged back to the die table, so that the inner diameter of the preformed hole on the upper surface of the preformed unit is smaller than the inner diameter of the preformed hole on the lower surface of the preformed unit.
It should be emphasized that, due to the need to install embedments, the upper surface of the prefabricated part is usually used as an inner facade in the forming mold; therefore, in this embodiment, the flexible layer 200 is set to be in a circular truncated cone shape with an outer diameter gradually increasing from the top end to the bottom end, so that on one hand, convenience in demolding can be improved, and on the other hand, a reserved hole structure with a small inner part and a large outer part can be formed on the prefabricated part, so that waterproof performance of the prefabricated part is improved.
Further, the bottom of the flexible layer 200 may be formed with a projection 220 in a truncated cone shape, and an inclination of an outer sidewall of the projection 220 may be greater than an inclination of an outer sidewall of the flexible layer 200. After the prefabricated part is processed, the slope of the wall of the preformed hole is smaller than that of the wall of the flaring hole, and therefore the anti-leakage capacity of the prefabricated part is further improved.
In addition, as another embodiment, the bottom of the flexible layer 200 may be further provided with a protruding portion 220 having a truncated cone shape, and a step structure is formed between the protruding portion 220 and the flexible layer 200. Of course, when the bottom of the flexible layer 200 is provided with the protrusion 220, the lower end of the stem may be exposed to the bottom end surface of the protrusion 220.
When a step structure is formed between the protrusion 220 and the flexible layer 200, the backbone is provided with a reinforcing structure at a position corresponding to a mesa of the step structure; when the reinforcing structure is a reinforcing ring 131, the upper ring surface of the reinforcing ring 131 can be substantially parallel to the mesa of the step structure, thereby improving the strength of the entire pore-forming module.
The part of the flexible layer 200 above the upper end of the skeleton is a head 210, and the height of the head 210 can be larger than that of the protrusion 220, so that the distance between the upper end of the skeleton and the inner vertical surface of the prefabricated part is increased, when the prefabricated part is demolded with the pore-forming mold, the head 210 can absorb the pulling force applied to the pore-forming mold by the prefabricated part and deform, and the top of the flexible layer 200 is prevented from being punctured by the upper end of the skeleton.
The embodiment also provides a forming mold of the prefabricated part, which comprises a bottom mold and a plurality of side molds arranged on the bottom mold, wherein the bottom mold and the plurality of side molds jointly form a forming cavity of the prefabricated part. The forming cavity can be provided with a plurality of hole forming modules, and the hole forming modules are hole forming modules in the embodiment and are used for forming a plurality of reserved holes on the prefabricated part.
Example 2
Referring to fig. 2, in the present embodiment, the outer sidewall of the stem is provided with external threads from the top to the bottom thereof. Specifically, after the stem is formed by turning, an external thread may be turned on the stem, and the external thread may be extended from the connection portion to the tip of the stem to form a structure similar to a screw.
When the outer side wall of the backbone is provided with external threads from the top to the bottom, the rubber material of the flexible layer 200 can enter the lines of the threads when pouring, so that the contact area between the flexible layer 200 and the backbone is increased, the connection strength between the flexible layer 200 and the framework is increased, and the overall anti-pulling performance of the pore-forming module is improved.
Example 3
Referring to fig. 3, in the present embodiment, the reinforcing structure may be at least 3 reinforcing protrusions 132 circumferentially disposed around the backbone, for example, 3, 4, 6, or more.
The reinforcing bump 132 and the backbone can be an integral structure formed by turning; in addition, after the stem is formed by turning, a plurality of reinforcing bumps 132 may be connected to the stem by welding to form the reinforcing structure.
In the same reinforcing structure, more than 3 reinforcing bumps 132 can be uniformly distributed in the circumferential direction of the backbone, so that the stress balance between the flexible layer 200 and the reinforcing structure is improved, and the flexible layer is prevented from being punctured by the reinforcing bumps 132.
The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, without departing from the spirit of the utility model, the person skilled in the art shall not inventively design the similar structural modes and embodiments to the technical solution, but shall fall within the scope of the utility model.
