Description

Technical Field

[0001] This utility model relates to the field of prefabricated component manufacturing technology, and in particular to a prefabricated component vertical mold that can fix a corrugated pipe. Background Technology

[0002] The production of precast components usually involves pre-assembling precast component molds, then pouring concrete into the molds, and removing the molds after the concrete has solidified to obtain the finished precast component.

[0003] Depending on design requirements, internal modules are typically incorporated into the precast component molds to form internal structures such as concrete pouring channels and cast-in-place zones. For example, in related technologies, corrugated pipes can be installed within the molds to construct concrete pouring channels.

[0004] The fabrication of precast components includes flat mold fabrication and vertical mold fabrication. Taking vertical mold fabrication as an example, the precast component mold is fixed between two adjacent mold boxes, and then the casting is carried out in a vertical state. After the casting is completed, the two mold boxes are separated, and then the mold and the cast precast component are removed together. After the mold is removed, the finished product is obtained.

[0005] However, taking the mold with corrugated pipe mentioned earlier as an example, the corrugated pipe has a poor fixing effect when the mold is erected and poured, and it is easily squeezed and deformed during the pouring process, which affects the quality of the finished precast component.

[0006] Therefore, this utility model is proposed. Utility Model Content

[0007] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a precast component vertical mold that can fix the corrugated pipe, so as to solve the technical problems in the related technology.

[0010] Optionally, the upper part of the mold frame is further provided with a top mold, and the upper end of the upper part of the core mold is connected to the top mold through a connecting mechanism.

[0011] Optionally, the mold frame is further provided with vertical reinforcing bars. The vertical reinforcing bars extend from bottom to top outside the corrugated pipe and the core mold, and continue to extend after exceeding the upper end of the core mold at the top. They bend towards the direction close to the vertical projection area of ​​the core mold and continue to extend upward after bending, so that the vertical projection plane of the part of the vertical reinforcing bars that continues to extend upward after bending is located in the horizontal section of the upper part of the core mold.

[0012] Optionally, the vertical projection plane of the portion of the vertical reinforcing bar that continues to extend upward after bending is located at the edge of the horizontal section of the upper part of the mandrel.

[0013] Optionally, the inner side of the top formwork is provided with a reinforcing bar fixing groove, and the upper part of the vertical reinforcing bar is disposed in the reinforcing bar fixing groove.

[0015] Optionally, at least one surface on the front and rear sides of the core mold is provided with a vertically penetrating steel bar groove; vertical steel bars are provided inside the mold frame, and the vertical steel bars are arranged in the steel bar groove.

[0016] This utility model provides a precast component vertical mold for fixing corrugated pipes.

This can play a supporting role during the concrete pouring process and prevent the corrugated pipe from deforming. The corrugated pipe is removed from the upper part of the anchoring area. In a preferred embodiment, a steel bar groove can also be reserved on the surface of the core mold. Attached Figure Description

Detailed Implementation

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] According to one aspect of this utility model, an embodiment of the present utility model provides a precast component vertical mold for fixing corrugated pipes, combined with... Figure 1-9 The mold includes a mold frame. The mold frame includes a bottom mold 1, the upper surface of which is provided with one or more flanges 2 with cavities. A bellows 3 is also provided inside the mold frame, the bottom of which is sleeved on the outside of the flanges 2. A core mold 4 is also provided inside the mold frame, which is coaxially arranged with the bellows 3. The core mold 4 includes an upper core mold 5 and a lower core mold 6. The lower core mold 6 passes through the bellows 3 until it extends into the inside of the flanges 2.

[0034] In traditional techniques, the corrugated pipe occupies the entire vertical reinforcing steel of the mold frame from top to bottom without effective support, making it prone to deformation during pouring. In this application, the corrugated pipe 3 is fixed at its bottom by a flange 2 set on the bottom mold 1. Simultaneously, the bottom of the core mold 4 is inserted into the corrugated pipe 3 to form support, thus fixing the anchorage area of ​​the precast wall corrugated pipe 3. Furthermore, the corrugated pipe 3 is only located in the bottom anchorage area; the upper part of the anchorage area is not the corrugated pipe 3, but rather the core mold 4. The core mold 4 is integrally formed in two parts, i.e., a one-piece mold. This provides support during concrete pouring, preventing deformation of the corrugated pipe 3.

[0035] The upper part of the mold frame is also provided with a top mold 7, which can be set above the mold box 8. The upper end of the core mold 4 is connected to the top mold 7 through a connecting mechanism 9. In this embodiment, the connecting mechanism 9 is a hanging structure, which allows the core mold 4 to be hung on the top mold 7 for fixation.

[0036] The mold frame also includes vertical reinforcing bars 10, which extend upwards from the bottom on the outside of the corrugated pipe 3 and the core mold 4. After exceeding the top of the core mold 4, the bars continue to extend and bend towards the vertical projection area of ​​the core mold 4, forming a bent portion 11. This ensures that the vertical projection plane of the portion 12 of the vertical reinforcing bar extending upwards after bending is located within the horizontal section of the upper part of the core mold 4. The purpose of this design is that, during the assembly of the upper and lower wall layers, the top of the vertical reinforcing bars 10 can extend into the upper corrugated pipe 3, i.e., the anchorage area, and form a bond with the cast-in-place concrete of the corrugated pipe 3, thus forming an anchorage and improving the connection strength of the precast components.

[0037] As an example, the vertical projection plane of the portion 12 extending upwards after the vertical reinforcing bar 10 is located at the edge of the horizontal section of the upper part of the mandrel 4. Since the corrugated pipe 3 at the bottom needs to remain inside the precast component after the concrete is poured, its corrugated surface and concrete form an interlock, increasing the bonding area between the concrete and the corrugated pipe 3 and improving the anchorage strength. The upper mandrel 4 needs to be removed. Because the vertical reinforcing bar 10 itself has a certain degree of elasticity, when the mandrel 4 is removed, it will move relative to the bent portion of the vertical reinforcing bar 10, thus being removed smoothly. Furthermore, since the vertical projection plane of the portion extending upwards after the bend is located at the edge of the horizontal section of the upper part of the mandrel 4, rather than the center, the mandrel 4 is less affected by the reinforcing bar during removal.

[0038] In this embodiment, the inner side of the top mold 7 is provided with a steel bar fixing groove 13, and the upper part of the vertical steel bar 10 is placed in the steel bar fixing groove 13, thereby fixing the position of the vertical steel bar 10.

[0039] On the left and right sides of the core mold 4, the side closest to the vertical reinforcing bar 10 (referred to as the vertical side 14) is set vertically, and the other side (referred to as the inclined side 15) is set at an angle. In this way, the vertically set side ensures that the core mold 4 is minimally affected by the vertical reinforcing bar 10 when it is pulled out, and the inclined side forms a wedge-shaped structure to reduce the resistance of the core mold 4 when it is pulled out.

[0040] In another embodiment, such as Figure 10-11 At least one of the front and rear sides of the core mold 4 has a vertically extending steel bar groove 16 on its surface; vertical steel bars 10 are provided inside the mold frame, and the vertical steel bars 10 are set in the steel bar groove 16 with their tops extending out of the steel bar groove 16. This also serves to fix the position of the vertical steel bars 10. In the precast component 17 produced, a concrete pouring channel 18 corresponding to the core mold 4 can be constructed, the bottom of which is a corrugated pipe embedded in the precast component 17.

[0041] In some other embodiments, such as Figure 12-13 The core mold 4 may not have a steel bar groove 16 on its surface, nor a steel bar fixing groove 13 on its top. Instead, it may use a post-insertion steel bar, that is, after the precast component 17 is made, steel bars are inserted into the concrete pouring channel 18 formed by the core mold to connect with the anchorage area of ​​the upper precast component.

[0042] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
