Description

Technical Field

[0001] The utility model relates to the technical field of building structure construction, in particular to an inner and outer template and a cylindrical foundation structure mold using the template. Background Art

[0002] In a pouring construction project, it is usually necessary to use a formwork to limit the pouring space. The existing formwork structure is simple and heavy, and cannot meet the existing pouring construction requirements.

[0003] As a new, lightweight, plug-in foundation structure, the barrel-type foundation structure is suitable for silt foundations with low bearing capacity. However, due to the huge size of the barrel-type foundation structure, a larger formwork is required during construction. The traditional formwork has poor sealing after assembly and is heavy, making it difficult to hoist and demould, and is increasingly unable to meet the construction needs of construction sites. Summary of the invention

[0004] The utility model solves the above problems through the following technical means:

[0005] The inner and outer formwork of the utility model comprises an outer formwork and an inner formwork which are relatively fixed by connecting bolts; the outer formwork comprises an outer formwork panel and an outer formwork truss which is arranged on the back of the outer formwork panel as a vertical support; the inner formwork comprises an inner formwork panel and an inner formwork truss which is arranged on the back of the inner formwork panel as a vertical support.

[0006] As a further improvement of the above technical solution, the back sides of the outer mold panel and the inner mold panel are welded with transverse ribs and vertical ribs.

[0007] Preferably, the outer formwork panel and the inner formwork panel include an 8 mm thick stainless steel composite plate and a guard plate provided on the back of the composite plate for connecting the outer formwork and the inner formwork together.

[0008] As a further improvement of the above technical solution, a plurality of lifting ears are provided on the top of the outer template and the top of the inner template.

[0009] As a further improvement of the above technical solution, a ladder is provided on one side of the back side of the outer template.

[0010] Preferably, sealing connection flanges are provided on the left and right sides of the outer template and the inner template.

[0011] The cylindrical basic structure mold of the utility model comprises an outer mold assembled from a plurality of straight outer mold plates and a plurality of arc-shaped outer mold plates, and an inner mold assembled from a plurality of inner mold plates respectively arranged at a plurality of compartments of the cylindrical basic structure.

[0012] As a further improvement of the above technical solution, two adjacent inner templates are connected by connecting angle plates.

[0013] As a further improvement of the above technical solution, an adjusting screw is provided on the inner side of the inner mold for connecting and controlling the inward and outward movement of the inner mold plate.

[0014] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0015] The inner and outer formwork of the utility model, the plate structure plus the truss structure as the vertical support, can not only ensure the verticality of the formwork installation, thereby ensuring that the casting space is parallel up and down and improving the casting quality, but also minimize the mass of the formwork to facilitate splicing and lifting; at the same time, the outer formwork truss and the inner formwork truss located on the back can also provide a manual working platform, which is convenient for manual operation during mold installation and mold removal operations and is easy to use.

[0016] The cylindrical foundation structure mold of the utility model has a simple structure and is light in weight. A plurality of outer molds and a plurality of inner molds assembled as a whole are hoisted or demoulded in sequence on both sides of the tied steel bars, thereby improving installation and disassembly efficiency, thereby improving construction efficiency and being able to meet the construction needs of the construction site.

[0028] Example 1

[0029] like Figures 1 to 5 As shown: the inner and outer formwork 1 described in this embodiment includes an outer formwork 1 and an inner formwork 2 relatively fixed by connecting bolts 4; the outer formwork 1 includes an outer formwork panel 11 and an outer formwork truss 12 provided on the back of the outer formwork panel 11 as a vertical support; the inner formwork 2 includes an inner formwork panel 21 and an inner formwork truss 22 provided on the back of the inner formwork panel as a vertical support.

[0030] The inner and outer formwork 1 described in this embodiment, the plate structure plus the truss structure as the vertical support, can not only ensure the verticality of the formwork installation, thereby ensuring that the casting space is parallel up and down and improving the casting quality, but also minimize the mass of the formwork to facilitate splicing and lifting; at the same time, the outer formwork truss 12 and the inner formwork truss located on the back can also provide a manual working platform, which is convenient for manual operation during mold installation and demolding operations and is easy to use.

[0031] As a further improvement of the above technical solution, transverse ribs 32 and vertical ribs 33 are welded on the backs of the outer mold panel 11 and the inner mold panel, which further enhances the strength of the outer mold panel 11 and the inner mold panel, avoids deformation, and prolongs the service life.

[0032] As a preferred implementation scheme of this embodiment, the outer mold panel 11 and the inner mold panel include an 8 mm thick stainless steel composite plate 35 and a protective plate 36 arranged on the back of the composite plate 35 for connecting the outer mold 1 and the inner mold 2 together.

[0033] As a further improvement of the above technical solution, the tops of the outer formwork 1 and the inner formwork 2 are both provided with a plurality of lifting ears 34 for facilitating lifting and bundling.

[0034] As a further improvement of the above technical solution, a ladder 13 is provided on one side of the back side of the outer formwork 1 to facilitate workers to climb to a high place to perform manual work.

[0035] As a preferred implementation of this embodiment, sealing connection flanges 31 are provided on the left and right sides of the outer template 1 and the inner template 2 to facilitate the splicing and fixing of the outer template 1.

[0036] Example 2

[0037] like Figure 6-Figure 8 As shown, the cylindrical basic structure mold described in this embodiment includes an outer mold 5 assembled from a plurality of straight outer mold plates 1 and a plurality of curved outer mold plates 1, and an inner mold 6 assembled from a plurality of inner mold plates 2 respectively arranged at a plurality of compartments of the cylindrical basic structure.

[0038] The cylindrical foundation structure mold described in this embodiment has a simple structure and is light in weight. The multiple outer molds 1 and the multiple inner molds 6 assembled as a whole are hoisted or demolded in turn on both sides of the tied steel bars, which improves the installation and disassembly efficiency, thereby improving the construction efficiency and meeting the construction needs of the construction site.

[0039] As a further improvement of the above technical solution, two adjacent inner templates 2 are connected by connecting angle plates 61, and the inner side of the inner template 6 is provided with an adjusting screw 62 for connecting and controlling the inner and outer movement of the inner template 2. Figure 6 , Figure 7 As shown, when the adjusting screw 62 is tightened, the inner formwork 2 is pushed outward by the adjusting screw 62 and combined with the connecting angle plate 61 into a mold assembly state. After pouring is completed, the adjusting screw 62 is loosened, and the two adjacent inner formworks 2 are retracted following the adjusting screw 62 and separated from the connecting angle plate 61 into a demolding state. At this time, there is a demolding gap between the inner mold 6 and the cast body, which can facilitate demolding.
