Detailed Description

The principles and spirit of the present utility model will be described below with reference to several exemplary embodiments shown in the drawings. It should be understood that these embodiments are described only to enable those skilled in the art to better understand and to practice the utility model, and are not intended to limit the scope of the utility model in any way.

Referring to fig. 1 to 15, an embodiment of the present utility model provides a prefabricated component mold assembly structure, including: a mould frame 1 and a fixed mould 2 for grouting sleeve in and out of a grout hole for vertical mould production. A grouting sleeve 3 is arranged in the die frame 1, and the grouting sleeve 3 comprises a slurry inlet hole 31 and a slurry outlet hole 32. It should be understood that the mould frame 1 here may be either a mould frame without insulating prefabricated parts or a mould frame with insulating prefabricated parts (i.e. for making sandwich walls), which when it is a mould frame with insulating prefabricated parts is defined as an inner leaf mould, with an insulating layer 4 and prefabricated part outer leaf moulds (indicated in fig. 1 by the outer leaf 5 having been poured) on the outside of the inner leaf mould. The composite structure may be lifted to a formwork erection platform, sandwiched between two adjacent formwork boxes, then poured with concrete to complete the fabrication of the prefabricated components, and finally the various parts of the mould composite structure removed to form the fabricated concrete structure 8.

As an example, the fixing mold 2 is substantially plate-shaped and includes a plurality of fixing portions 21 arranged at intervals, and in this embodiment, the fixing portions 21 are substantially stripe-shaped extending along the vertical direction, although other suitable shapes may be adopted. The fixing portions 21 are integrally formed with each other, and in this embodiment, the portion connecting the fixing portions 21 is referred to as a connecting portion 22, and as an example, the connecting portion 22 is substantially in a strip shape along the horizontal direction, but other suitable shapes are also possible. Since the gaps 23 remain between the fixing portions 21, the gaps 23 can still be filled with concrete poured into the mold frame 1, so that the prefabricated member does not occupy too much concrete space, and the lack of concrete is reduced relative to the continuous form (i.e., the gaps 23 are still filled to form the concrete 6). The fixing mold 2 fixes the pulp inlet hole 31 and the pulp outlet hole 32 through the first fixing hole 24 and the second fixing hole 25, respectively, and as an example, the first fixing hole 24 and the second fixing hole 25 may be respectively sleeved on the outer circumferential surfaces of the pulp inlet hole 31 and the pulp outlet hole 32, and the fixing effect may be achieved because the first fixing hole 24 and the second fixing hole 25 are sized and configured to be matched with the pulp inlet hole 31 and the pulp outlet hole 32.

Further, the outer surface of the stationary mold 2 does not exceed the outermost plane of the mold frame 1 in the thickness direction. For example, in the present embodiment, the outer surface of the fixed mold 2 is flush with the outermost plane of the mold frame 1 in the thickness direction, so that the flatness of the outer side of the mold frame can be ensured during the production of the vertical mold, and no gap is left to prevent slurry leakage when the whole mold assembly structure is clamped by the adjacent mold boxes of the vertical mold manufacturing platform.

Optionally, the connecting portion 22 is located at upper ends of the plurality of fixing portions 21, so as to connect the upper ends of the plurality of fixing portions 21 together.

Alternatively, the connection portion 22 is located at the lower ends of the plurality of fixing portions 21, thereby connecting the lower ends of the plurality of fixing portions 21 together.

Further, the mold frame 1 further includes a top mold 12, a bottom mold, and a side mold 11 to enclose the composite mold frame 1. The side form 11 includes a first assembling portion 111, a second assembling portion 112, and a third assembling portion 113 disposed between the first assembling portion 111 and the second assembling portion 112, where the first assembling portion 111, the second assembling portion 112, and the third assembling portion 113 can be assembled to form a reinforcing bar hole 114 through which a reinforcing bar of the prefabricated member passes. The side mold 11 is constructed in a combination way, and when the ends of two horizontal steel bars 7 are connected through the closed end 71, the closed end 71 is not required to be provided with a strip-shaped hole corresponding to the closed end 71. As an example, further, two sides of the third assembly part 113 are provided with half holes 113a, and the side sides of the first assembly part 111 and the second assembly part 112 close the half holes 113a to form the reinforcement holes 114. However, since the distance between the two horizontal bars 7 may be narrowed in some cases, it is necessary to design the half hole 113a to be long, that is, the inner side of the half hole 113a is closer to the middle of the third assembly part 113, and at this time, the horizontal bars 7 are limited in diameter, so that the whole long half hole is not completely filled, leaving a spare part, and slurry leakage is caused. To solve this problem, the side form 11 further includes a flange 115 closing the empty portion of the reinforcing bar hole 114. In this embodiment, flanges 115 are respectively provided on the first and second segments 111 and 112 to close the vacant portions of the reinforcing bar holes 114.

Further, a key groove is also formed on the third assembly portion 113 to replace the rough surface (not shown in the drawings) of the prefabricated member.

Further, the bottom die also belongs to a combined structure, and comprises a bottom die main body 13 of the die frame 1 and a bottom die combined part 26 connected with the fixed die 2.

Alternatively, if the connecting portion 22 is located at the lower ends of the plurality of fixing portions 21, the lower ends of the plurality of fixing portions 21 are connected together; at this time, the bottom die assembly part 26 is connected to the lower end of the connecting part 22, and is bent inwards along the direction perpendicular to the connecting part 22, and is connected to the bottom die main body 13, and the bottom die assembly part 26 is provided with a mounting hole 261 for connecting with the bottom die main body 13;

alternatively, if the connecting portion 22 is located at the upper ends of the plurality of fixing portions 21, the upper ends of the plurality of fixing portions 21 are connected together; at this time, the bottom die assembly part 26 is connected to the lower end of the fixing part 21;

optionally, the bottom die assembly and the connecting portion are connected to form a structure 27 (also having a mounting hole 261 thereon) having a substantially uniform thickness, and are connected to the lower end of the fixing portion 21.

Referring to fig. 16-18, the stationary mold 2 may be constructed as a split, i.e., divided into segments with gaps left between the segments. The fixing portion 21 is provided with a connecting hole, such as a screw hole 28, and a screw and an electric wrench are used to form a self-supporting and disassembling action during mold disassembly, and an adhesive tape and the like are used for sealing during mold assembly. Compared with the schemes of other embodiments, the split type design has higher rigidity than a long series of consecutive designs, and is free from deformation caused by falling on the ground. In addition, the repeated utilization rate is high, and the same sleeve interval can be used universally.

Specific examples are set forth herein to illustrate the utility model in detail, and the description of the above examples is only for the purpose of aiding in understanding the core concept of the utility model. It should be noted that any obvious modifications, equivalents, or other improvements to those skilled in the art without departing from the inventive concept are intended to be included in the scope of the present utility model.
