Description

Technical Field

[0001] The present invention relates to a bubble suppression bucket device for pouring fresh concrete, and particularly to a bubble suppression bucket device for pouring fresh concrete that utilizes gravity to pour fresh concrete at a low flow rate and reduces the generation of bubbles in the concrete.

Background Art

[0002] Generally, in the process of building construction, concrete is widely used as a main material. When using concrete, mainly various materials are put into a concrete mixer for mixing and stirring to form fresh concrete with fluidity and plasticity. Then, the concrete is pumped into a formwork using a concrete pump device and hardened and solidified to form various-shaped structures.

[0003] However, in the process of transporting concrete by the pump of the concrete pump device, a large amount of air is mixed into the concrete, so a large amount of bubbles remain in the concrete. After the concrete is hardened and solidified, the bubbles in the concrete form holes, which not only reduce the structural strength after hardening and solidification but also affect the aesthetics. Generally, bubbles with a diameter exceeding 100 μm are regarded as "bubbles with high harmfulness", and this type of bubbles has the most significant impact on the performance of concrete. Bubbles with a diameter of 100 - 50 μm are regarded as "bubbles with medium harmfulness", and although their impact is not as great as that of bubbles with high harmfulness, they still require attention. Bubbles in the range of 50 - 20 μm in diameter are regarded as "bubbles with low or no harmfulness" and usually do not have a significant impact on the structural performance in concrete. Bubbles with a diameter of less than 20 μm are regarded as beneficial bubbles, and the uniform presence of these bubbles in the concrete can give the concrete a certain stability.

[0004] Before concrete hardens and solidifies, it is possible to use vibrators or tamping rods to vibrate and agitate it, which helps to remove air bubbles from the concrete. However, since vibrators and tamping rods require slow, manual operation, this leads to wasted labor costs and time. [Overview of the project] [Problems that the invention aims to solve]

[0005] Reducing the labor required during the injection of ready-mix concrete and suppressing the generation of air bubbles is a matter of urgency.

[0006] The objective of this invention is to provide a bubble-suppressing bucket device for injecting ready-mix concrete that can inject ready-mix concrete at a low flow rate using gravity, thereby reducing the generation of air bubbles in the concrete. [Means for solving the problem]

[0007] The bubble-suppressing bucket device for injecting ready-mixed concrete according to the present invention includes at least a frame, a bucket, and a valve body, wherein the frame is capable of being stably erected on the ground and is provided with a plurality of suspension holes on the outer circumference of its top, the bucket is installed on the frame and has an outlet at its bottom and can hold a certain amount of ready-mixed concrete and be used for injecting ready-mixed concrete, and the valve body is installed facing the bottom of the outlet and can open and close the outlet. [Effects of the Invention]

[0008] According to this invention, when the outlet is closed with the valve, the user lifts the frame and moves it to the position of the concrete mixer, puts concrete into the bucket, then lifts the frame and moves it to the concrete injection destination, opens the outlet with the valve, and injects the concrete in the bucket at a low flow rate using gravity, thereby controlling and suppressing the generation of air bubbles.

[Modes for carrying out the invention]

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It goes without saying that the present invention is not limited to the embodiments described below.

[0011] The bubble-suppressing bucket device for injecting ready-mix concrete according to the present invention includes at least a frame 10, a bucket 20, and a valve body 30.

[0012] The frame 10 is capable of being stably erected on the ground and is equipped with a plurality of suspension holes 11 provided on the outer circumference of its top.

[0013] The bucket 20 is mounted on the frame 10 and has an outlet 21 at its bottom, allowing it to hold a certain amount of concrete and be used for injecting ready-mix concrete. Bucket 20 has a rectangular or square funnel structure in plan view. A plurality of ribs 22 are respectively installed on the outer periphery of the bucket 20.

[0014] The valve body 30 is installed facing the bottom of the outlet part 21 and can open and close the outlet part 21. The valve body 30 is pivotally attached to the outlet part 21 of the bucket 20. At least one handle 31 is installed on the valve body 30.

[0015] Furthermore, it includes a transparent partition plate 40 installed above the concrete injection point B. The transparent partition plate 40 is arranged corresponding to the lower part of the bucket 20, and during the injection of fresh concrete, the user can check the fresh concrete injection situation through the transparent partition plate 40. At least one opening 41 is provided on the transparent partition plate 40, and fresh concrete can pass through the opening 41.

[0016] Furthermore, it includes a hose 50. One end of the hose 50 is connected to the outlet part 21 of the bucket 20 and is used to circulate fresh concrete. The hose 50 is a flexible tube.

[0017] When using the air bubble suppression bucket device for fresh concrete injection, the hook A of the crane is connected by using the suspension hole 11 at the top of the frame 10 (see Fig. 2), and the frame 10 can be lifted by the crane and moved to the position of the concrete mixer or the concrete injection point B. When the frame 10 is moved to the position of the concrete mixer (not shown) and the valve body 30 closes the outlet part 21 of the bucket 20 (see Fig. 2), the concrete stirred by the concrete mixer can be put into the bucket 20. After the concrete in the bucket 20 reaches a certain amount, the frame 10 is lifted and moved to the concrete injection destination B (see Fig. 3). The valve body 30 opens the outlet 21 of the bucket 20 (see Figs. 3 and 4), and the concrete placed in the bucket 20 is injected at a low flow rate using gravity, and air bubbles are discharged during the process of the concrete flowing at a low flow rate (not shown), thereby achieving the purpose of controlling and suppressing the generation of air bubbles.

[0018] In addition, in a preferred embodiment of the present invention, the bucket 20 has a rectangular or square funnel structure in plan view. Preferably, a plurality of ribs 22 are respectively installed on the outer periphery of the bucket 20 (see Figs. 1 to 4), and the structural strength of the bucket 20 can be strengthened by the ribs 22. However, the bucket 20 may select a funnel structure of other shapes.

[0019] In addition, in an embodiment of the present invention, the valve body 30 is pivotally attached above the outlet 21 of the bucket 20 (see Figs. 1 to 4), and the user can rotate the valve body 30 to control the opening and closing of the outlet 21 of the bucket 20. Preferably, at least one handle 31 is installed on the valve body 30 (see Figs. 1 to 4) so that the user can control the valve body 30 using the handle 31.

[0020] In a preferred embodiment of the present invention, it further includes a transparent partition plate 40 installed above the concrete injection destination B (see Fig. 5). The transparent partition plate 40 is arranged corresponding to the lower part of the bucket 20 (see Fig. 6). When the user performs the operation of injecting fresh concrete, the situation of injecting fresh concrete can be confirmed through the transparent partition plate 40. And at least one opening 41 is provided on the transparent partition plate 40 (see Fig. 5), and the opening 41 can allow fresh concrete to pass through.

[0021] In another preferred embodiment of the present invention, a hose 50 is further included, with one end of the hose 50 connected to the outlet 21 of the bucket 20, and the other end of the hose 50 extended and positioned at the concrete injection destination B (see Figures 6 and 7), and the hose 50 is used to circulate the ready-mix concrete. The concrete flowing out from the outlet 21 of the bucket 20 is accurately sent through the hose 50 to the concrete injection destination B, and injection can be carried out.
