Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to an outer formwork cylinder for concrete pouring. Background Technology

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. Concrete pouring molds are generally divided into inner molds and outer molds. They are mainly used for grouting and pouring operations of cylindrical building structures. In municipal facilities, inspection wells are usually poured using this method.

[0003] The concrete pouring external formwork in related technologies typically consists of multiple layers of pouring cylinders. Adjacent layers of pouring cylinders are connected by fasteners. Workers can increase or decrease the number of pouring cylinders to achieve pouring operations for buildings of different heights. Each layer of pouring cylinder includes two semi-circular pouring slabs, and the ends of adjacent pouring slabs are connected by fasteners.

[0004] However, in the use of external molds in related technologies, the sealing between adjacent pouring cylinders relies solely on the contact between their end faces, resulting in poor sealing stability. Furthermore, the pouring cylinders are prone to deformation during prolonged use or transportation, affecting the sealing effect between adjacent layers. Using external molds for pouring operations can also lead to concrete slurry leakage, impacting the pouring quality and requiring improvement. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a concrete pouring outer mold cylinder that can improve the sealing stability between two adjacent pouring cylinders, reduce the risk of concrete slurry seepage, and thus ensure the pouring quality.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a concrete casting outer mold cylinder, comprising multiple layers of casting cylinders, with adjacent layers of casting cylinders connected by multiple fastening bolts, each layer of casting cylinder comprising two semi-circular casting plates, the two sides of the two casting plates being tightly abutted together and connected by multiple bolt lugs, each casting plate having a semi-circular sealing edge fixedly connected to the outer edge of the top of the top of the top of the top of the top of the bottom ...

[0007] In a preferred embodiment, the present invention can be further configured such that the cross-section of the sealing strip is semi-circular, and the inner wall of the sealing groove matches the outer wall of the sealing strip.

[0008] In a preferred embodiment, the present invention can be further configured such that a guide slope is provided at the inner edge of the top of the sealing edge.

[0009] In a preferred embodiment, the present invention can be further configured such that: a semi-circular sealing lip is fixedly connected to the bottom of the stepped groove, the cross-section of the sealing lip is a right triangle, and the hypotenuse of the sealing lip matches the guide slope.

[0010] In a preferred embodiment, this utility model can be further configured such that: two limiting posts are vertically fixedly connected to the top of each sealing edge, and two limiting grooves are provided at the bottom of each step groove, and the limiting posts match the corresponding limiting grooves, so as to achieve limiting after the adjacent two layers of casting cylinders are stacked and installed.

[0011] In a preferred embodiment, the present invention can be further configured such that the four limiting columns of each layer of the casting cylinder are arranged at 90° intervals, so that after the casting cylinders are stacked and installed, the gaps on both sides of adjacent layers of casting cylinders can be misaligned.

[0012] In a preferred embodiment, the present invention can be further configured such that a sealing layer is provided on both sides of each of the casting slabs.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. By combining the sealing edge with the stepped groove, and by combining the sealing strip with the sealing groove, multiple seals are achieved between two adjacent pouring cylinders, which effectively improves the sealing stability between the two adjacent pouring cylinders, reduces the risk of concrete slurry seepage, and thus ensures the pouring quality.

[0015] 2. Because a guide slope is provided at the inner edge of the top of the sealing edge, the sealing strip can quickly deform under the action of the guide slope during the stacking and installation of two adjacent layers of casting cylinders, so that the two adjacent layers of casting cylinders can be installed smoothly. At the same time, the bevel of the sealing lip can tightly abut against the guide slope, thereby improving the sealing effect. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1 , Figure 2 A concrete casting outer formwork includes multiple layers of casting cylinders 1, with adjacent layers of casting cylinders 1 connected by multiple fastening bolts 2. Each layer of casting cylinder 1 includes two semi-circular casting plates 11, with the two sides of the two casting plates 11 tightly abutting each other and connected by multiple bolt lugs 12.

[0022] Reference Figure 1 , Figure 2 Each casting slab 11 has a semi-circular sealing edge 13 integrally formed at the outer edge of its top and a stepped groove 14 at the outer edge of its bottom. When two adjacent casting cylinders 1 are stacked, the sealing edge 13 can be tightly inserted into the corresponding stepped groove 14 to achieve a seal between the two adjacent casting cylinders 1.

[0023] Reference Figure 1 , Figure 2 A semi-circular sealing strip 15 is fixedly connected to the inner wall of the stepped groove 14, and a sealing groove 16 is provided on the inner wall of the sealing edge 13. When two adjacent layers of casting cylinder 1 are stacked and installed, the sealing strip 15 can be tightly inserted into the corresponding sealing groove 16, thereby achieving a re-sealing between the two adjacent layers of casting cylinder 1.

[0024] By utilizing the cooperation between the sealing edge 13 and the stepped groove 14, and the cooperation between the sealing strip 15 and the sealing groove 16, multiple seals are achieved between two adjacent layers of casting cylinder 1, which effectively improves the sealing stability between the two adjacent layers of casting cylinder 1, reduces the risk of concrete slurry seepage, and thus ensures the casting quality.

[0025] Reference Figure 1 , Figure 2 The sealing strip 15 has a semi-circular cross-section, and the inner wall of the sealing groove 16 matches the outer wall of the sealing strip 15, so that the sealing strip 15 can undergo elastic deformation smoothly when two adjacent layers of casting cylinders 1 are stacked. At the same time, a guide slope 3 is integrally formed at the inner edge of the top of the sealing edge 13, which further ensures that the sealing strip 15 can undergo elastic deformation smoothly, so as to facilitate the smooth installation of two adjacent layers of casting cylinders 1.

[0026] Reference Figure 1 , Figure 2The bottom of the stepped groove 14 is fixedly connected with a semi-circular sealing lip 4. The cross-section of the sealing lip 4 is a right triangle, and the hypotenuse of the sealing lip 4 matches the guide slope 3, thereby improving the sealing effect between the sealing edge 13 and the stepped groove 14 and reducing the risk of concrete slurry seepage.

[0027] Reference Figure 1 , Figure 3 Each casting slab 11 has a sealing layer 5 on both sides, so that when two casting slabs 11 are joined together to form a casting cylinder 1, the two sides of the two casting slabs 11 are stably sealed, thereby improving the sealing effect of the casting cylinder 1 itself and reducing the risk of concrete slurry seepage.

[0028] In this embodiment, the sealing strip 15, the sealing lip 4, and the sealing layer 5 are made of rubber material. Of course, in other embodiments, elastic materials such as latex or silicone can also be used, which will not be listed in detail here.

[0029] Reference Figure 1 , Figure 3 Two limiting posts 6 are vertically fixed to the top of each sealing edge 13, and two limiting grooves 7 are provided at the bottom of each step groove 14. When two adjacent layers of casting cylinder 1 are stacked and installed, the limiting posts 6 can be inserted into the corresponding limiting grooves 7 to achieve the limiting after the two adjacent layers of casting cylinder 1 are stacked and installed.

[0030] Reference Figure 1 , Figure 3 The four limiting columns 6 of each layer of casting cylinder 1 are arranged at 90° intervals so that after the casting cylinder 1 is stacked and installed, the gaps on both sides of the two adjacent layers of casting cylinder 1 can be staggered, which effectively improves the sealing effect and reduces the risk of concrete slurry seepage.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
