Description

Technical Field

[0001] The invention relates to the technical field of hanging plate casting, and in particular to a prefabricated pipe pile hanging plate concrete segmented casting and sealing plate device and a construction process. Background Art

[0002] Layered concrete pouring is a method of pouring concrete in layers of defined thickness during the concrete pouring process. The basic principle is to rationally divide the pouring layers so that each layer can be covered by newly poured concrete before initial setting, thereby ensuring the integrity and good performance of the concrete structure. This method primarily considers factors such as heat dissipation during the pouring process, vibration compaction, and preventing cracks in the concrete.

[0003] Concrete pouring layers include: full layering, segmented layering and oblique layering. For prefabricated pipe pile hanging slab concrete structure, since its structural thickness is not large but the area is large, the prefabricated pipe pile hanging slab concrete structure adopts segmented pouring method.

[0004] Since the prefabricated pipe pile hanging slab concrete structure adopts the segmented pouring method, it is necessary to seal the end of each segmented concrete pouring. After pouring, the sealed surface needs to be roughened. However, since the contact surface between the hanging slab concrete and the prefabricated pipe pile is not flat, it is easy to touch the surface of the prefabricated pipe pile during the roughening process. Improper operation can easily scratch the surface of the prefabricated pipe pile, resulting in a decrease in the overall waterproof performance of the hanging slab. In addition, due to high-altitude operations, the roughening process also requires the construction of a steel frame, which is inconvenient.

[0005] In order to facilitate later construction and reduce the possibility of damage to prefabricated pipe piles, reduce the later roughening process, and also to reduce the inclination of the hanging plate, so as to facilitate the adjustment of the inclination during hanging plate casting, the present invention provides a prefabricated pipe pile hanging plate concrete segmented casting and sealing plate device and construction process.

Obviously, the described embodiments are not all embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0067] It should be noted that, unless otherwise specifically stated, the relative arrangements of components and steps, and numerical expressions set forth in these embodiments should not be construed as limiting the scope of the present invention.

Technologies, methods, and apparatus known to those skilled in the art may not be discussed in detail herein, but to the extent applicable, such technologies, methods, and apparatuses should be considered part of this specification.

[0069] Example 1

[0070] This embodiment provides a prefabricated pipe pile hanging plate concrete segmented casting sealing device, such as Figure 1 As shown, it includes a first fixing member 1, a tooth groove template 2, and a second fixing member 3. The first fixing member 1 is fixedly connected to the prefabricated pipe pile 4, and the second fixing member 3 is fixedly connected to the steel bar support system 5 on the surface of the hanging plate; the tooth groove template 2 is arranged between the first fixing member 1 and the second fixing member 3; the inner surface of the tooth groove template 2 is provided with a plurality of bosses 201;

[0071] like Figure 2 As shown, a sinking platform is provided on the inner side of the first fixing member 1, one end of the tooth groove template 2 is provided in the sinking platform, and a first connecting member 6 is provided on the inner side of the tooth groove template 2 for fixing one end of the tooth groove template 2 in the sinking platform; specifically, the upper end of the tooth groove template 2 has a step, the lower end of the first connecting member 6 is provided in the step of the tooth groove template 2, and the inner side of the first connecting member 6 is flush with the inner surface of the tooth groove template 2.

[0072] like Figure 3As shown, a groove is provided on the inner side of the second fixing member 3, and the other end of the tooth groove template 2 is embedded in the groove. A second connecting member 7 is provided on the inner side of the tooth groove template 2 for fixing one end of the tooth groove template 2 embedded in the groove.

[0073] As a preferred embodiment, Figure 2 As shown, an embedding groove is provided on the inner side of the sink of the first fixing member 1, and the first connecting member 6 includes a first limiting plate 601 and a second limiting plate 602. The second limiting plate 602 is arranged perpendicular to the first limiting plate 601. The upper end of the first limiting plate 601 is embedded in the embedding groove, and the lower end of the first limiting plate 601 is used to fix the tooth groove template 2; the upper surface of the second limiting plate 602 abuts the first fixing member 1. The width of the upper end of the first limiting plate 601 is smaller than the width of the embedding groove, thereby allowing the first connecting member 6 to be adjusted left and right to adapt to the inclination of the tooth groove template 2.

[0074] A flexible gasket 8 is provided between the upper surface of the second limiting plate 602 and the first fixing member 1 to cushion the pressure on the first fixing member 1 during pouring. A flexible pad 9 is provided between the outer surface of the notch formwork 2 and the first fixing member 1, and a flexible pad 9 is provided between the outer surface of the notch formwork 2 and the second fixing member 3 to reduce the pressure exerted by the notch formwork on the second fixing member 3 during pouring.

The surface where the connecting plate 10 connects to the prefabricated pipe pile 4 is an arcuate surface. The connecting plate 10 is fixedly connected to the inner side surface of the first fixing member 1. The surface where the connecting plate 10 connects to the first fixing member 1 is flat and conforms to the inner side surface of the first fixing member 1. The connecting plate 10 converts the arcuate connection between the first fixing member 1 and the prefabricated pipe pile 4 into a flat connection, thereby enhancing the connection strength between the first fixing member 1 and the prefabricated pipe pile 4.

[0076] A steel pipe 11 is provided on the outer side of the notch formwork 2. Horizontal tie bars 12 are provided on the notch formwork 2.

After pouring, the tie bars 12 are poured into the slab, and the steel pipe 11 can be removed and reused. The tie bars 12 and the steel pipe 11 are used to offset the pressure of the poured concrete on the notch formwork 2, thereby preventing the notch formwork 2 from exerting excessive pressure on the first fixing member 1 and the second fixing member 3, which could lead to cracks between the first fixing member 1 and the connecting member 10, or between the second fixing member 3 and the steel support system 5, and thus quality problems.

[0077] As a preferred embodiment, Figure 2As shown, a first fastener 13 is provided at the contact point between the tooth groove template 2 and the first connecting member 6, and the first fastener 13 securely connects the first connecting member 6 to the tooth groove template 2. Specifically, a stepped hole is provided on the first limiting plate 601 of the first connecting member 6, and the first fastener 13 is provided in the stepped hole. The other end of the first fastener 13 is threadedly connected to the tooth groove template 2.

Specifically, a step hole is provided on the second connecting member 7, and the second fastener 15 is provided in the step hole. The other end of the second fastener 15 is threadedly connected to the tooth groove template 2.

[0079] like Figure 4 As shown, the boss 201 of the tooth groove template 2 is a rectangular boss, and a vertical hole 14 is provided in the boss 201. The vertical hole 14 is used to allow cooling air to pass through, and the cooling air is used to locally cool the poured concrete.

[0080] Example 2

[0081] The difference between this embodiment and the first embodiment is that the structure of the boss 201 is as follows: Figure 5 As shown, both side surfaces of the boss 201 are inclined surfaces, and the inclination directions of the two side surfaces are the same, and the inclination angles are both less than 5°.
