Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a structural column winnowing basket mechanism. Background Technology

[0002] In building construction, structural columns are important structural components that enhance the overall integrity and stability of buildings. In the traditional construction process of structural columns, a hopper is usually set up to assist in the pouring of concrete and vibration.

[0003] In the prior art, Chinese patent publication number CN221399835U discloses a structural column slurry outlet mechanism, including a template slurry outlet and a baffle. The upper end of the template has a pouring port, and the slurry outlet is set on the pouring port of the template. Its bottom extends vertically downward to form a grout-blocking baffle. The baffle is slidably connected between the template and the slurry outlet to seal the pouring port. It is in close contact with the grout-blocking baffle, and a grout collection groove is also provided at the lower end of the baffle. This structural column slurry outlet mechanism increases the contact area between the bottom of the slurry outlet and the baffle by setting a grout-blocking baffle, thereby reducing grout leakage. In addition, a grout collection groove is set at the bottom of the baffle to catch the leaked grout, thereby solving the problem of mortar settling and affecting the construction environment.

[0004] The aforementioned patent provides a slurry-filled column hopper mechanism primarily to address the issue of grout leakage. However, in practice, after constructing the structural column using this hopper mechanism, a large amount of concrete tends to accumulate inside. If this concrete cannot be drained promptly, it will solidify inside the hopper, making cleaning difficult. Existing slurry-filled column hopper mechanisms lack a mechanism for draining the internal concrete, hindering the rapid cleaning of the hopper after the structural column is poured. Utility Model Content

[0005] The purpose of this utility model is to provide a structural column hopper opening mechanism, which aims to improve the problem that the existing structural column hopper opening mechanism does not have a mechanism for discharging the concrete inside, and it is inconvenient to quickly clean the inside of the hopper opening mechanism after the structural column is poured.

[0006] This utility model is implemented as follows:

[0007] A structural column hopper opening mechanism includes a hopper, with symmetrical slide rails on both sides of the bottom opening of the hopper, a sealing plate between the two slide rails, and a screw rod vertically downward at the front end of the hopper. The bottom end of the screw rod passes through the sealing plate to fix the position of the sealing plate. A guide rail is provided at the end of the hopper facing the structural column template, and a baffle is provided between the guide rail and the structural column template. The baffle can move up and down relative to the guide rail, and a guide plate is inclinedly provided at the bottom of the baffle.

[0008] Preferably, a connecting column is provided vertically downward at the front end of the winnowing basket, and a threaded groove is provided in the middle of the connecting column; the slide rail has an L-shaped structure; and suspension columns are provided on both sides of the winnowing basket near the top and bottom.

[0009] Preferably, the guide rail is inserted into the inside of the winnowing basket, and the end of the guide rail facing the inside of the winnowing basket is provided with a guide opening, and the other end of the guide rail is provided with a fixing rod, and the fixing rod is provided with multiple bolt holes from top to bottom.

[0010] Preferably, the sealing plate is inserted into the slide rail on both sides, and the front end of the sealing plate is symmetrically provided with grips on both sides, and the sealing plate is provided with through holes at the position aligned with the screw.

[0011] Preferably, the top end of the screw is threadedly connected to the threaded groove, and a nut is provided at the end of the screw that passes through the sealing plate, the nut being pressed against the sealing plate.

[0012] Preferably, the baffle has a cutting edge at the top and multiple countersunk holes at the bottom near the guide plate, and handles at the bottom of both sides of the baffle.

[0013] Preferably, the basket also includes handles, which are disposed on both sides of the basket and are fixed to the basket by bolts.

[0014] Preferably, the handle has two connecting rods on its side, and the ends of the connecting rods have fixing plates with multiple fixing holes. Bolts pass through the fixing holes to fix the handle to the side of the winnowing basket.

[0015] Preferably, it also includes a limiting hook, the rear end of which is provided with multiple mounting holes from top to bottom, and the bottom of the limiting hook is provided with a hanging opening, and the limiting hook is provided with a set screw aligned with the hanging opening.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model features sliding rails on both sides of the bottom opening of the winnowing basket. These rails allow for the removal of a sealing plate, facilitating the discharge of residual concrete from the basket after the structural column is poured. Simultaneously, a guide rail at the end of the winnowing basket facing the structural column formwork is connected to a baffle. This baffle is inserted upwards from the bottom of the guide rail after the structural column construction is completed, separating the residual concrete from the concrete inside the winnowing basket and the concrete inside the structural column, preventing them from solidifying together. Furthermore, a guide plate at the bottom of the baffle guides the concrete during discharge, facilitating concrete recycling.

[0018] 2. This utility model, by installing handles on both sides of the winnowing basket, makes it convenient for workers to operate the winnowing basket, making it easy to hold and disassemble the winnowing basket, greatly facilitating the flexible use of the winnowing basket.

[0019] 3. This utility model provides a limiting hook, which allows for convenient positioning of the winnowing basket, facilitating its installation at the opening at the top of the structural column template. The limiting hook also makes it easy to assemble and disassemble the winnowing basket. Attached Figure Description

Then, insert the sealing plate 2 into the bottom opening of the hopper 1 and fix the sealing plate 2 with the screw 3. Then, concrete can be injected into the structural column using the hopper 1. After the structural column concrete is poured, concrete will remain inside the hopper 1. At this time, the worker needs to push the baffle 4 from the bottom of the guide rail 7 upward along the guide opening 73, so that the baffle 4 separates the concrete inside the structural column from the concrete inside the hopper 1. Then fix the position of the baffle 4, unscrew the screw 3, and pull out the sealing plate 2, so that the concrete inside the hopper 1 can flow out smoothly from the hopper 1. After the concrete inside the hopper 1 is discharged, remove the hopper 1 and the limiting hooks 6, and transfer it to the next structural column that needs to be constructed. However, the guide rail 7 and the baffle 4 cannot be removed, so multiple guide rails 7 and baffles 4 need to be prepared.

[0058] In summary, compared with the prior art, this application provides slide rails 13 on both sides of the bottom opening of the hopper 1. The sealing plate 2 can be pulled out through the slide rails 13, making it convenient to remove the sealing plate 2 after the structural column is poured, thus facilitating the discharge of the concrete trapped inside the hopper 1. At the same time, a guide rail 7 is provided at one end of the hopper 1 facing the structural column formwork. A baffle 4 is inserted between the guide rail 7 and the structural column formwork. The baffle 4 is convenient to be inserted from the bottom of the guide rail 7 upwards after the structural column construction is completed. The baffle 4 separates the concrete trapped inside the hopper 1 from the concrete inside the structural column, preventing the concrete inside the hopper 1 from solidifying together with the concrete inside the structural column. At the same time, a guide plate 44 is provided at the bottom of the baffle 4, which can guide the concrete when discharging the concrete trapped inside the hopper 1, facilitating the recycling of the concrete.
