Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering tools, in particular to a reusable hopper tool for casting construction columns. Background Technique
[0002] A construction column is a vertical member set at the main corner parts of a wall or when the wall exceeds a set height. It is a concrete column made according to the construction sequence of first building the wall and then casting the concrete column. The density of the concrete column can effectively ensure the stiffness and stability of the construction column, and is used to improve the overall stiffness and overall ductility of the building. A construction column with qualified casting quality can, together with the ring beam, strengthen the connection of the longitudinal and transverse walls, improve the shear and bending resistance of the wall, restrain the development of wall cracks, and effectively resist the action of earthquakes on the building. Therefore, the casting quality of the construction column is particularly crucial in construction.
[0003] To ensure the density of the concrete at the top during the casting of the construction column, a wooden formwork is conventionally used to make a hopper at the construction site and fixed on the formwork of the construction column for concrete casting. However, this structure cannot be removed until the concrete solidifies, resulting in poor fluidity during construction. Moreover, after the formwork is removed, concrete blocks in the shape of "triangular prisms" will be formed at the hopper, which need to be chiseled after the concrete solidifies, consuming a large amount of labor costs, and the risk coefficient for workers to perform high-altitude chiseling operations is extremely high.
[0004] Therefore, setting a hopper structure that can be used in the casting of construction columns and is easy to disassemble and turnover can play a huge role in the casting process of construction columns. Content of the Utility Model
[0005] In order to solve the problems existing in the above background technique, the purpose of the utility model is to provide a reusable hopper tool for casting construction columns. By setting a hopper support, a baffle and a hopper, after opening the baffle, the main structure of the construction column is cast by feeding materials from the hopper. After the casting is completed, the baffle is covered and fixed, so that the top of the construction column is filled densely and solidified in one time. The hopper support is detachably connected to the hopper, which is convenient for the repeated turnover and utilization of the hopper, and improves the construction efficiency of the construction column.
[0006] The utility model realizes the above technical purpose through the following technical solutions:
[0007] A reusable hopper tool for casting construction columns includes a hopper support, a baffle and a hopper. The baffle is movably connected to the hopper support, and the hopper is detachably connected to the hopper support and located outside the baffle.
[0008] As a further preferred solution of the above technical solution: an opening is provided at the upper end of the hopper support, and the baffle is movably connected below the opening.
[0009] A further preferred solution is as follows: at least one baffle is provided on the dustpan mouth support, and the baffle is limited and fixed by the baffle.
[0010] A further preferred solution is as follows: a plurality of card slots are further provided on the dustpan mouth support, and the plurality of card slots are symmetrically arranged on both sides of the opening.
[0011] As a further preferred solution to the above technical solution: the baffle is hinged to the dustpan mouth support through a hinge.
[0012] As a further preferred solution to the above technical solution: the dustpan mouth is a right-angled triangular prism structure, which includes a bottom support plate and two side plates, and the bottom support plate is obliquely connected to the bottoms of the two side plates.
[0013] A further preferred solution is as follows: a plurality of cards are provided on the side plate, and each card is clamped on the corresponding card slot.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. By detachably connecting the dustpan mouth to the dustpan mouth support, it is convenient for the repeated turnover and utilization of the dustpan mouth. At the same time, by using the baffle that rotates and cooperates with the dustpan mouth support, the remaining concrete in the dustpan mouth is filled to the top of the structural column, so that the top of the structural column is poured in one time, replacing the "triangular prism" structure formed by the existing tools for pouring, reducing the workload of later chiseling and repairing, and effectively saving the construction process.
[0016] 2. The use of the utility model can not only improve the construction quality of the concrete pouring of the structural column, but also reduce the construction cost, reduce the safety risk, improve the construction efficiency, and has a broad promotion prospect in the industry.

[0028] Refer to Figure 1-7 , the present utility model proposes a reusable dustpan opening tool for pouring structural columns. The tool is made of metal material as a whole. To reduce the weight of the tool, aluminum alloy material is preferably used. It includes a dustpan opening support 1, a baffle 2 and a dustpan opening 3. The baffle 2 is movably connected to the dustpan opening support 1, and the dustpan opening 3 is detachably connected to the dustpan opening support 1, and the dustpan opening 3 is located outside the baffle 2.
[0029] Specifically, the size of the dustpan opening support 1 is 350mm * 350mm. An opening 4 is provided at the upper end of the dustpan opening support 1. Refer to Figure 3-5 , the opening 4 is located in the middle of the upper end of the dustpan opening support 1. The size of the opening 4 is 150mm * 150mm. The baffle 2 is connected to the dustpan opening support 1 below the opening through a hinge 7. The size of the baffle 2 is 150mm * 150mm.
[0030] As Figure 2 , Figure 5 , Figure 7As shown in the figure, at least one retaining piece 5 is provided on the dustpan mouth support 1. The retaining piece 5 is rotatably connected to the dustpan mouth support 1 by a pin shaft. After the baffle 2 is pushed up to be parallel to the opening 4, the retaining piece 5 is rotated to the horizontal state to limit and fix the baffle 2.
[0031] Furthermore, a plurality of card slots 6 are also provided on the dustpan mouth support 1. As Figure 2 , Figure 4 , Figure 6 shown, the plurality of card slots 6 are symmetrically arranged on both sides of the opening 4. In this embodiment, a total of four card slots 6 are provided, and they are symmetrically distributed in pairs on both sides of the opening 4.
[0032] Referring to Figure 2-3 , the dustpan mouth 3 is a right triangular prism structure, and its dimensions of length * width * height are 200mm * 200mm * 200mm. It includes a bottom support plate 8 and two side plates 9. The bottom support plate 8 is inclinedly connected to the bottoms of the two side plates 9 to form a feeding channel. A plurality of cards 10 are provided on the side plates 9. In this embodiment, a total of four cards 10 are provided, and they are symmetrically and fixedly connected to both sides of the side plates 9. Each card 10 is clamped in the corresponding card slot 6, which is convenient for quickly disassembling the dustpan mouth 3 from the dustpan mouth support 1 or installing it on the dustpan mouth support 1. Embodiment 2
[0033] A reusable dustpan mouth tool for pouring construction columns, which is used as a part of the construction column formwork. During actual application:
[0034] First, the dustpan mouth support 1 is attached to the wall of the construction column close to the ring beam, and the dustpan mouth support 1 is fixed with four 1-cm-long cement nails. Two of the cement nails support the bottom of the dustpan mouth support 1, and the other two cement nails are respectively clamped on the left and right sides of the dustpan mouth support 1;
[0035] Then, the construction column formwork located below the dustpan mouth support 1 is installed by using tie rods;
[0036] After the formwork installation is completed, as Figure 3-5 shown, the baffle 2 is opened. The dustpan mouth 3 is connected to the dustpan mouth support 1 through the cooperation of the cards 10 and the card slots 6. At this time, the baffle 2 is attached to the bottom support plate 8. Concrete is poured through the feeding channel of the dustpan mouth 3. When the height of the concrete in the construction column is 3 cm away from the top of the column, stop pouring the concrete. Manually push up the baffle 2 to ensure that the remaining concrete in the dustpan mouth 3 fills the top of the entire construction column during the process of the upper leg of the baffle. When the baffle 2 is flush with the dustpan mouth support 1, rotate the retaining piece 5 to lock the baffle 2 (at this time, it is the Figure 1-2 shown state), ensuring that the concrete in the construction column does not leak.
[0037] Finally, clean the remaining materials on the dustpan opening 3, and detach the dustpan opening 3 from the dustpan opening support 1. Refer to Figure 7 . Thus, the concrete pouring of the structural column is completed. Transfer and install the dustpan opening 3 onto the next structural column to be poured.
[0038] Application cases and effects:
[0039] When this utility model is used at the construction site, compared with the existing construction methods, it can bring greater economic and environmental benefits.
[0040] (1) Using the conventional construction method in the early stage, it is necessary to chisel the protruding "triangular prism" concrete blocks. It is estimated that the number of structural columns that need to be chiseled and repaired is 1,100. 10 structural columns are chiseled and repaired every day, and the daily chiseling cost of the workers is 400 yuan. The total cost for repair is 1100 / 10*400 = 44,000 yuan.
[0041] (2) After using the tool of this utility model, the cost of the tool is 150 yuan per piece. A total of 6 pieces are made on-site, and the cost is 150*6 = 900 yuan.
[0042] Therefore, after using the tool of this utility model, the cumulative cost savings is 44,000 - 900 = 43,100 yuan. The amount of work for chiseling the structural columns in the later stage is reduced by approximately 1,100, the cost is reduced by 43,100 yuan, and the construction efficiency on-site is improved. At the same time, the environmental pollution and noise pollution caused by concrete grinding and repair on-site are reduced, which conforms to the principles, policies, and concepts of energy conservation, emission reduction, pollution control, haze reduction, and green environmental protection.
[0043] It should be clear that the above detailed description of the embodiments of the present utility model provided in the drawings is only for further illustration of the present utility model, and is not intended to limit the scope of the present utility model to be protected. Instead, it only represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, some non-essential improvements and adjustments made by those of ordinary skill in the art according to the above content of the present utility model all fall within the protection scope of the present utility model.
