Description

Technical Field

[0001] This utility model relates to the field of trumpet mouth technology, specifically an integrated structural column trumpet mouth. Background Technology

[0002] Structural columns are important lateral force resisting components in building structures. They are often set at the corners of masonry walls, the intersections of longitudinal and transverse walls, and the four corners of stairwells. Their core function is to form a spatial skeleton with components such as ring beams and ground beams, thereby enhancing the integrity and ductility of the walls and improving the crack resistance of buildings under horizontal forces such as earthquakes and wind loads. Structural columns are made of reinforced concrete cast-in-place. During construction, the walls must be built first and toothed joints must be reserved. After the walls are completed, a second pour is made to ensure a tight bond between the structural columns and the walls. Since structural columns are secondary structures, there are construction joints when the tops are connected to the main structures such as frame beams and floor slabs. The narrow space can easily lead to incomplete concrete pouring. The traditional flared opening has become a key structural measure to solve this construction difficulty.

[0003] During construction, an inverted conical flared formwork is erected at the top of the structural column to create a gradually decreasing space at the bottom and a larger top. This provides operational space for concrete pouring and vibration to ensure a full top. The construction process includes reserving the position of the structural column, erecting the flared formwork, pouring concrete from the top, and manually chiseling away the excess concrete at the flared end until it is flush with the bottom of the beam after the concrete has set. As a temporary structure for the construction of the structural column, this is a necessary measure to ensure the density of the concrete at the top. However, after the traditional flared construction, the excess concrete needs to be manually chiseled away with a pneumatic pick or chisel. The process is cumbersome, inefficient, and can easily damage the edges of the structural column. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated structural column bell mouth to solve the problem that after the construction of traditional bell mouths, it is necessary to manually remove excess concrete with a pneumatic pick or chisel, which is a cumbersome and inefficient process.

[0006] An integrated structural column bell mouth includes a main frame, a casting hole is opened on the surface of the main frame, a feeding hopper is fixedly connected to the surface of the main frame, a slidable shaping steel sheet is provided on the inner wall of the casting hole, a push plate is fixedly connected to the side of the shaping steel sheet facing the feeding hopper, and a handle is fixedly connected to the outer side of the main frame.

[0007] Preferably, the shaped steel sheet is fixedly connected to a vertically arranged reinforcing rib on the side facing the feed hopper.

[0008] Preferably, a pointed cone is fixedly connected to the bottom end of the reinforcing rib.

[0009] Preferably, the top end and the bottom end of the reinforcing rib are fixedly connected with the surface of the shaped steel sheet by welding respectively, the outer side of the main frame is fixedly connected with a guide positioning plate, and the guide positioning plate is provided with a guide hole for the reinforcing rib to penetrate.

[0010] Preferably, the bottom end of the feeding hopper is smoothly connected with the bottom wall of the pouring hole.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] 1. The integrated construction column trumpet mouth avoids defects such as surface damage, corner loss and the like of the construction column caused by chiseling in the traditional process, cancels the post chiseling process, shortens the construction time of a single construction column, reduces the chiseling labor, reduces the labor cost, and avoids dust pollution caused by chiseling.

[0013] 2. The rigid limiting structure is formed by cooperation of the guide positioning plate and the guide hole, the shaped steel sheet is forced to move along the vertical direction, deviation or shaking during manual force application is avoided, the cutting action is ensured to be stable and controllable, and the operation difficulty is reduced.
