Description

Technical Field

[0001] This utility model relates to the field of post-cast strip pouring technology, and in particular to a small post-cast strip pouring device. Background Technology

[0002] A post-cast strip is a temporary construction joint left at corresponding positions in the foundation slab, walls, and beams according to design or construction specifications. Post-cast strips are an effective measure to address differential settlement and reduce shrinkage stress, and are therefore widely used in engineering. In building construction, to prevent harmful cracks that may occur in cast-in-place reinforced concrete structures due to uneven shrinkage or settlement, concrete strips are left at corresponding positions in the foundation slab, walls, and beams according to design or construction specifications. There are four types of post-cast strip joints: straight joints, stepped joints, grooved joints, and X-shaped joints. The width is generally 700-1000mm, with 800mm, 1000mm, and 1200mm being the most common. If the building has significant settlement issues, post-cast strips can be used to address them. However, during construction, the two parts of the post-cast strip need to be temporarily separated, and then joined together to form a whole after construction is completed.

[0003] When assembling two parts into a single unit, a pouring device is required. Typically, the post-pouring strip cannot be poured until 28 days after the concrete has set. If pouring must wait until the main structure of the building is completed or until the concrete on both sides has set, at least 60 days are needed. Currently, concrete is generally poured directly, with the concrete manually transported to the post-pouring strip. The concrete's self-flow and subsequent vibration are used to ensure uniformity. However, when multiple post-pouring strips need to be poured at a particular location, manual pouring is labor-intensive and inefficient. Utility Model Content

[0004] In order to overcome the shortcomings of existing technologies, such as large workload and low efficiency in manual pouring, this utility model provides a small post-pouring strip pouring device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a small post-pouring strip pouring device, including a mobile trolley, a fixed plate on the mobile trolley, one end of the fixed plate is hinged to the mobile trolley, the other end of the fixed plate is connected to the mobile trolley through a telescopic cylinder, the bottom of the telescopic cylinder is hinged to the mobile trolley, the output end of the telescopic cylinder is hinged to the fixed plate, a conveying pipe is fixed on the fixed plate, a spiral feeding screw is provided inside the conveying pipe, a hopper is provided at the upper part of one end of the conveying pipe, a pouring pipe is provided at the lower part of the other end of the conveying pipe, and a conveying motor connected to the spiral feeding screw inside the conveying pipe is provided on the fixed plate.

[0006] As a further improvement of this utility model, the conveying pipeline is connected to the casting pipe through a bend.

[0007] As a further improvement of this utility model, the bottom of the mobile trolley is provided with several hydraulic support columns.

[0008] As a further improvement of this utility model, a support plate is provided at the bottom of the hydraulic support column.

[0009] As a further improvement of this utility model, a handle is provided on the outside of the casting pipe.

[0010] As a further improvement of this utility model, a flexible hose is provided at the outlet of the casting pipe.

[0011] Compared with the prior art, the present invention has the following advantages: In this solution, the operator manipulates the mobile trolley to a suitable position, operates the telescopic cylinder to adjust the angle of the conveying pipe so that the pouring pipe is directly above the post-pouring strip, and the conveying motor controls the rotation of the screw feeder. The screw feeder pours the concrete in the hopper into the post-pouring strip through the pouring pipe. When pouring multiple post-pouring strips, it saves time and labor, reduces the labor intensity of workers, and improves work efficiency. Attached Figure Description
