Description

Technical Field

[0001] This utility model relates to the field of prefabricated component manufacturing mold technology, specifically to a detachable wind tunnel forming structure applied to arc-shaped component molds. Background Technology

[0002] Currently, in curved components with wind tunnels, both the side core mold and the center core mold have wind tunnels, and the forming mold at the wind tunnel has a single function. It needs to be completely disassembled during demolding. The mold at the wind tunnel has a large contact area with the concrete, resulting in high demolding resistance and difficult operation. This leads to a high rate of concrete damage at the edge of the hole, and at the same time, grout leakage is easy at the joint. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a detachable wind tunnel forming device for arc-shaped component molds, the specific technical solution of which is as follows:

[0004] A detachable wind tunnel forming structure for use in arc-shaped component molds is provided for installation between the side walls of two side core molds and the two wind tunnel reserved positions on the left and right sides of the middle core mold of the arc-shaped component. The structure includes a main body, comprising a top plate and a bottom plate. Upper wedge-shaped side plates are provided on the left and right sides of the top plate; lower wedge-shaped side plates are provided on the left and right sides of the bottom plate. The two upper wedge-shaped side plates are mirror-symmetrical; the two lower wedge-shaped side plates are mirror-symmetrical; the top plate, bottom plate, two upper wedge-shaped side plates, and two lower wedge-shaped side plates form a cuboid structure with front and rear openings; the upper and lower wedge-shaped side plates on the same side are fixed together by bolts; the two upper wedge-shaped side plates are connected to the top plate, and the two lower wedge-shaped side plates are connected to the bottom plate.

[0005] Preferably, at least two sets of double connecting ears are provided at equal intervals on the top and bottom edges of the intermediate core mold near its cavity, where the wind tunnel is reserved; the top plate and bottom plate are provided with a bearing seat corresponding to the position of each set of double connecting ears, the bearing seat being located in the middle of each set of double connecting ears, and the shaft hole of the bearing seat corresponding to the ear hole of the connecting ear; the front ends of the top plate and bottom plate are respectively hinged to the intermediate core mold through the ear hole and shaft hole via a rotating shaft.

[0006] Preferably, the left and right sides of the rotating shaft are provided with limit pin holes near the ends along its radial direction, and anti-disengagement pins are provided in the limit pin holes.

[0007] Preferably, the side wall of the side core mold is provided with a plurality of first positioning holes, and the back plates of the upper wedge-shaped side plate and the lower wedge-shaped side plate are provided with second positioning holes at the positions used for the first positioning holes; the first positioning holes and the second positioning holes are connected by positioning cones.

[0008] Preferably, the upper wedge-shaped side plate and the lower wedge-shaped side plate are also provided with several ribs at equal intervals along their width direction.

[0009] Preferably, the inner walls of the top plate and bottom plate on the side away from the intermediate core mold are also provided with hand handles.

[0010] More preferably, the width of both the top plate and the bottom plate is less than the sum of the heights of the upper wedge-shaped side plate and the lower wedge-shaped side plate.

[0011] Furthermore, preferably, sealing gaskets are provided at the connections between the top plate and the upper wedge-shaped side plate, the upper wedge-shaped side plate and the lower wedge-shaped side plate, and the lower wedge-shaped side plate and the bottom plate.

[0012] More preferably, when the arc-shaped component requires a wind tunnel structure, the rear ends of the bottom plate and top plate, and the rear ends of the upper wedge-shaped side plate and lower wedge-shaped side plate are all bolted to the outer side wall of the side core mold; the front ends of the upper wedge-shaped side plate and lower wedge-shaped side plate are bolted to the inner side wall of the intermediate core mold; the front ends of the top plate and bottom plate are hinged to the connecting lug of the intermediate core mold through a bearing seat and fixed to the inner side wall of the intermediate core mold with bolts.

[0013] When the arc-shaped component does not require a wind tunnel structure, remove all bolts, pull out the two upper wedge-shaped side plates and the two lower wedge-shaped side plates. The front ends of the top plate and the bottom plate are hinged to the connecting lugs of the intermediate core mold only through the shaft seat and flipped to the inside of the mold cavity of the intermediate core mold. Then, use the sealing component to seal the wind tunnel reserved area of ​​the intermediate core mold and the bolt holes and the first positioning hole of the side core mold side wall.

[0014] The beneficial effects of this utility model are:

[0015] 1. Compared with traditional wind tunnel inlet forming molds, this utility model only requires opening wind tunnel inlets on both sides of the central core mold, and the side core mold does not need to be opened, so that the preparation of two types of arc-shaped components with or without wind tunnels can be realized at the same time.

[0016] 2. This utility model, by setting a hinged top plate and bottom plate, and bolted upper and lower wedge-shaped side plates, allows for quick demolding and easy demolding when wind tunnel casting is not required. The top plate and bottom plate can be flipped into one side of the cavity of the middle core mold, and then the upper and lower wedge-shaped side plates can be pulled out. The wind tunnel opening on the middle core mold and the bolt holes and positioning holes on the side core molds can then be sealed. This method can quickly achieve demolding and is easy to demold, and is less likely to cause damage to the edges of the holes, thus effectively improving production efficiency.

[0017] 3. All joints of the components of this utility model are equipped with sealing gaskets, which effectively solves the problem of grout leakage in the gaps. Attached Figure Description

Detailed Implementation

[0028] The specific implementation of a detachable wind tunnel forming structure for arc-shaped component molds provided by this utility model will be further described with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-2 The diagram illustrates a detachable wind tunnel forming structure for use in arc-shaped component molds. It is primarily installed between the side walls of the two side core molds 2 and the two pre-reserved wind tunnel locations on the left and right sides of the central core mold 1. Notably, this invention only requires pre-reserved wind tunnel openings on the central core mold 1. In contrast, traditional wind tunnel molds require pre-reserved wind tunnel structures on both the central core mold 1 and the side core molds 2, which are inconvenient for sealing, prone to grout leakage at the joints, and have a larger contact area between the mold and concrete at the wind tunnel locations, making demolding difficult.

[0030] like Figure 4As shown, the structural body 3 includes a top plate 301 and a bottom plate 302; wherein, upper wedge-shaped side plates 303 are provided on the left and right sides of the top plate 301; and lower wedge-shaped side plates 304 are provided on the left and right sides of the bottom plate 302; the top plate 301, bottom plate 302, two upper wedge-shaped side plates 303, and two lower wedge-shaped side plates 304 together form a cuboid structure with openings at the front and back. Preferably, the two upper wedge-shaped side plates 303 and the two lower wedge-shaped side plates 304 are mirror-symmetrical. During installation, the upper wedge-shaped side plates 303 and the lower wedge-shaped side plates 304 on the same side are fixed together with bolts; the two upper wedge-shaped side plates 303 are butted together with the top plate 301, and the two lower wedge-shaped side plates 304 are butted together with the bottom plate 302.

[0031] like Figure 5-6 As shown, at least two sets of double connecting ears 101 are equally spaced on the top and bottom edges of the reserved wind tunnel of the intermediate core mold 1 near its mold cavity; the top plate 301 and the bottom plate 302 are each provided with a bearing 305 corresponding to the position of each set of double connecting ears 101, wherein the bearing 305 is located in the middle of each set of double connecting ears 101 and the shaft hole of the bearing 305 corresponds to the ear hole of the connecting ear 101; during installation, the front ends of the top plate 301 and the bottom plate 302 are respectively hinged to the intermediate core mold 1 through the ear hole and the shaft hole via a rotating shaft.

[0032] like Figure 3 As shown, the left and right sides of the rotating shaft are provided with limit pin holes near the ends along its radial direction. Anti-detachment pins 4 are provided in the limit pin holes to prevent the rotating shaft from detaching from the ear hole or shaft hole when the top plate 301 or bottom plate 302 rotates.

[0033] Preferably, the side wall of the side core mold 2 is provided with a plurality of first positioning holes, and the back plates of the upper wedge-shaped side plate 303 and the lower wedge-shaped side plate 304 are provided with second positioning holes 6 at the positions used for the first positioning holes (e.g., Figure 7-8 As shown), the first positioning hole and the second positioning hole 6 are connected by a positioning cone, thereby ensuring the accuracy of the installation position when the structure is connected to the mold, and ensuring that the wind tunnel is free of deviation after the detachable wind tunnel forming device is reused.

[0034] To ensure the mechanical stability of the structure, the upper wedge-shaped side plate 303 and the lower wedge-shaped side plate 304 are also provided with several ribs 5 at equal intervals along their width direction.

[0035] To facilitate the rotation of the top plate 301 and the bottom plate 302 during disassembly and assembly, a hand handle 306 is provided on the inner wall of the top plate 301 and the bottom plate 302 on the side away from the intermediate core mold 1.

[0036] More preferably, the widths of the top plate 301 and the bottom plate 302 are both less than the sum of the heights of the upper wedge-shaped side plate 303 and the lower wedge-shaped side plate 304, so as to ensure that when the structure is dismantled, the top plate 301 and the bottom plate 302 can be smoothly flipped to one side of the mold cavity of the intermediate core mold 1.

[0037] To address the issue of grout leakage at the joints, the present invention provides sealing gaskets (not shown in the figure) at the connection surfaces of the top plate 301 and the upper wedge-shaped side plate 303, the upper wedge-shaped side plate 303 and the lower wedge-shaped side plate 304, and the lower wedge-shaped side plate 304 and the bottom plate 302.

[0038] The specific method of using this utility model is as follows:

[0039] When the curved component requires a wind tunnel structure, the rear ends of the top plate 301 and bottom plate 302, and the rear ends of the upper wedge-shaped side plate 303 and lower wedge-shaped side plate 304 are all bolted to the outer side wall of the side core mold 2; the front ends of the upper wedge-shaped side plate 303 and lower wedge-shaped side plate 304 are bolted to the inner side wall of the intermediate core mold 1; the front ends of the top plate 301 and bottom plate 302 are hinged to the connecting lug 101 of the intermediate core mold 1 through the bearing seat 305 and simultaneously fixed to the inner side wall of the intermediate core mold 1 with bolts, further improving the tightness of the connection between the components and avoiding grout leakage during pouring;

[0040] When the arc-shaped component does not require a wind tunnel structure, remove all bolts, pull out the two upper wedge-shaped side plates 303 and the two lower wedge-shaped side plates 304. At this time, the front ends of the top plate 301 and the bottom plate 302 are hinged to the connecting lug 101 of the intermediate core mold 1 only through the bearing seat 305. Then, flip the top plate 301 and the bottom plate 302 to one side of the mold cavity of the intermediate core mold 1. Then, use the existing sealing components to seal the wind tunnel reserved area of ​​the intermediate core mold 1 and several bolt holes and the first positioning hole on the side wall of the side core mold 2.

[0041] This invention, by incorporating hinged top and bottom plates and bolted upper and lower wedge-shaped side plates, enables rapid assembly and disassembly, facilitates demolding, and minimizes damage to the edges of openings. This effectively improves production efficiency while also solving the problem of grout leakage through gaps. Compared to traditional wind tunnel molding structures, only wind tunnel openings need to be created on both sides of the central core mold, reducing the contact area between the mold and concrete at the wind tunnel location and effectively lowering the breakage rate during concrete demolding.
