Description

Technical Field

[0001] This utility model relates to the technical field of steel molds for reinforcing concrete pouring in manholes, and more specifically, to a combined steel mold for reinforcing concrete pouring in manholes. Background Technology

[0002] Inspection wells, as a major urban drainage facility, are mostly located on road surfaces. As a weak point in urban roads, inspection wells are prone to subsidence and collapse. Therefore, it is necessary to pour reinforced concrete at the wellhead to form a reinforcing concrete. Currently, when pouring reinforcing concrete at the wellhead, there is no device to block the concrete in the reinforcing concrete, which can easily lead to the collapse of the undried concrete, thus causing trouble for the pouring of the reinforcing concrete. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a combined steel mold for pouring reinforced concrete for inspection wells, which can prevent the concrete poured at the wellhead of the inspection well from collapsing, thus facilitating the pouring of reinforced concrete.

[0004] This utility model provides a combined steel mold for reinforcing concrete pouring in inspection wells, including an inner steel cylinder and an outer steel cylinder. The inner steel cylinder is coaxially arranged inside the outer steel cylinder, and the upper end face of the inner steel cylinder is on the same horizontal plane as the upper end face of the outer steel cylinder. The upper end of the inner steel cylinder and the upper end of the outer steel cylinder are fixed by several connecting plates that are circumferentially spaced. The lower end of the inner steel cylinder protrudes from the lower end of the outer steel cylinder and is used to insert into the inspection well and abut against the inner wall of the inspection well. The lower end of the outer steel cylinder is supported on the upper end of the inspection well. A pouring area for pouring reinforcing concrete at the upper end of the inspection well is formed between the inner steel cylinder and the outer steel cylinder.

[0005] By adopting the above structure, the lower end of the inner steel cylinder is inserted into the manhole of the inspection well, and the lower end of the outer steel cylinder abuts against the upper end of the inspection well. A pouring area for pouring reinforcement concrete can be formed between the inner and outer steel cylinders. When the concrete is poured into this pouring area, the concrete collapse can be avoided, which can facilitate the pouring of reinforcement concrete.

[0006] In one possible implementation, one end of each connecting plate is welded and fixed to the upper end of the inner steel cylinder, and the other end of each connecting plate is welded and fixed to the upper end of the outer steel cylinder. With this structure, both ends of each connecting plate can be reliably fixed to the upper ends of the inner steel cylinder and the upper ends of the outer steel cylinder, respectively, and the inner and outer steel cylinders can be reliably fixed together.

[0007] In one possible implementation, an annular conical surface is provided on the outer wall of the lower end of the inner steel cylinder; with this structure, during the process of inserting the inner steel cylinder into the inspection well, the annular conical surface can cooperate with the inner wall of the inspection well opening to guide the lower end of the inner steel cylinder into the inspection well opening.

[0008] In one possible implementation, the combined steel formwork for reinforcing concrete pouring of the inspection well also includes a lifting plate; the lifting plate is used to fix the upper ends of the inner and outer steel cylinders, and a lifting ring is fixed in the middle of the upper end of the lifting plate; with this structure, when the inner and outer steel cylinders need to be removed from the inspection well and the reinforcing concrete, the lifting plate can be fixed to the upper ends of the inner and outer steel cylinders, and the lifting plate, inner and outer steel cylinders can be lifted by the cooperation of the hook and the lifting ring, so that the inner and outer steel cylinders can be removed from the inspection well and the reinforcing concrete.

[0009] In one possible implementation, the lower end face of the lifting plate is provided with clearance grooves that correspond vertically to several connecting plates. Each connecting plate is used to fit into the clearance groove at the corresponding position from bottom to top so that the lower end face of the lifting plate is in close contact with the upper end face of the inner steel cylinder and the upper end face of the outer steel cylinder. With this structure, when the lifting plate is fixed to the upper end of the inner and outer steel cylinders, the clearance grooves can avoid the connecting plates, thereby enabling the lifting plate to be reliably fixed to the upper end of the inner and outer steel cylinders, which facilitates the lifting of the lifting plate, the inner steel cylinder and the outer steel cylinder.

[0010] In one possible implementation, the upper end of the inner steel cylinder is provided with a plurality of first threaded holes circumferentially, and the lifting plate is provided with first countersunk holes corresponding vertically to the plurality of first threaded holes. The lifting plate and the upper end of the inner steel cylinder are fastened together by first bolts passing through the first countersunk holes and threadedly connected to the first threaded holes. The upper end of the outer steel cylinder is provided with a plurality of second threaded holes circumferentially, and the lifting plate is provided with second countersunk holes corresponding vertically to the plurality of second threaded holes. The lifting plate and the upper end of the inner steel cylinder are fastened together by second bolts passing through the second countersunk holes and threadedly connected to the second threaded holes. With this structure, the lifting plate can be reliably fixed together with the upper ends of the inner steel cylinder and the upper ends of the outer steel cylinder.

[0011] In one possible implementation, a connecting hole is vertically provided in the middle of the lifting plate, and the threaded part of the lifting ring is threadedly connected to the connecting hole; by adopting this structure, the lifting ring can be reliably fixed in the middle of the lifting plate.

The lower end of the outer steel cylinder 2 is supported on the upper end of the inspection well 4. A pouring area 6 for pouring reinforcing concrete 5 at the upper end of the inspection well 4 is formed between the inner steel cylinder 1 and the outer steel cylinder 2.

[0021] One end of each connecting plate 3 is welded and fixed to the upper end of the inner steel cylinder 1, and the other end of each connecting plate 3 is welded and fixed to the upper end of the outer steel cylinder 2.
