Abstract
Description
Technical Field
[0001] The utility model relates to the field of concrete construction equipment for building projects, in particular to an auxiliary tool for pouring secondary structural columns. Background Art
[0002] Secondary structure refers to the structural part added on the basis of the main structure to meet the functional and aesthetic requirements of the building, mainly including structural columns, lintels, ring beams, infill walls, etc. In modern building structures, the main structure and the secondary structure are closely related. They are interdependent and supportive of each other, and together constitute a complete building system. Among them, the secondary structural column, as one of the commonly used structural components in buildings, has the function of increasing the stability and seismic performance of the building.
[0003] The traditional method of pouring structural columns usually sets a dustpan mouth slightly higher than the column head on one side of the column top, and then uses an ash bucket filled with concrete to pour concrete into the dustpan mouth, and then the concrete slowly flows into the structural column formwork. During the reciprocating process, the structural column formwork is constantly and gently tapped, so that the concrete falls due to the knocking vibration, bubbles float up, and vibrates and compacts. However, during the pouring of concrete, it was found that when the traditional ash bucket pours concrete into the dustpan mouth, a large amount of concrete will be scattered around. However, it is stipulated in the engineering that the dust on the ground is prohibited from being reused, which will cause a waste of resources and an increase in material loss. At the same time, when the top of individual structural columns is close to the bottom of the board, the ash bucket is often restricted from use due to its large size and lack of operating space, leaving quality risks. There is even a phenomenon of using a shovel to shovel concrete into the dustpan mouth, which reduces work and efficiency, increases working hours, and thus increases engineering costs. Therefore, there is an urgent need for an auxiliary tool that can be used to cast secondary structural columns. Utility Model Content
[0004] The content of the utility model is used to introduce the concepts in a brief form, which will be described in detail in the following specific implementation. The content of the utility model is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.
[0005] In view of the problems and shortcomings in the prior art, the purpose is to provide an auxiliary tool for pouring secondary structural columns. The utility model can overcome the concrete dripping when pouring secondary structural columns by installing a first handle and a second handle on a PVC loading pipe, and setting one end of the PVC loading pipe as a bevel. In addition, the manufacturing materials of the utility model can be taken on site, so it has strong turnover and applicability, and is more environmentally friendly to use. In order to solve the problems raised in the above background technology.
[0006] To achieve the above purpose, the utility model provides the following technical solutions: including a charging tube, the charging tube is a tubular structure with two ends open, one end of the charging tube is set as a beveled surface, and the other end is connected through a bottom plugging cap, the barrel of the charging tube is symmetrically provided with handle mounting holes on both sides, the two ends of the first handle are respectively inserted into the handle mounting holes and bent inwards to be fixed, and the outer side of the bottom plugging cap is also connected to a second handle. During use, the construction personnel can hold the first handle with one hand to lift the charging tube, and hold the second handle with the other hand to assist in lifting the charging tube, so that the charging tube can be lifted more easily and the concrete pouring can be completed, which can save time and effort for the construction personnel when performing the operation.
[0007] Preferably, a reinforcing bolt is added at the connection between the bottom plugging cap and the charging tube. The bottom plugging cap is selected to match the size of the charging tube, and the bottom plugging cap and the charging tube are connected by glue. However, in order to ensure the stability of the connection between them, a plurality of reinforcing bolts are added around the connection between the bottom plugging cap and the charging tube for further tightening to improve safety during use.
[0008] Preferably, the first handle is formed by bending φ4 steel bars. φ4 steel bars indicate that the diameter of the steel bars is 4 mm. Steel bars have good tensile strength and compressive strength, and cracks are not easily generated on the surface of the bent part after being bent. They are a material with high strength and good toughness.
[0009] Preferably, the second handle is formed by connecting a plurality of wooden strips by bolts. The second handle is a wooden handle, and specifically three wooden strips with a thickness of 1 cm and a width of 3 cm can be used, which are connected to each other by bolts to form a groove-shaped handle structure.

[0010] Preferably, the bevel angle of the beveled end of the charging tube is 45 degrees. One end of the charging tube is set as a beveled surface, and its bevel angle is optimally set to 45 degrees. Not only can the concrete in the charging tube be poured quickly and conveniently, but also the state of the concrete pouring process can be observed in real time. The posture and pouring method during pouring can be adjusted in time according to the state observed in real time, so as to minimize the spillage of concrete during pouring.
[0011] Preferably, the charging tube is a PVC tube with a diameter of 150 mm. The charging tube made of PVC tube is light in weight, low in cost, and easy to carry and turn over. In addition, the inner wall of the tube is smooth and has a low friction coefficient, which can prevent excessive contamination of the charging tube when it is reused. The diameter of the PVC tube is 150 mm, so it can be used even in special cases where it is inconvenient to support a flare or a 10 cm wide small-size structural column, thereby increasing the scope of use and ensuring construction quality.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model has a simple structure, quick assembly and disassembly, and a low technical threshold, and can realize standardized mass production.

Handle mounting holes 4 are symmetrically opened on both sides of the barrel of the charging tube 1. The two ends of the first handle 3 are respectively inserted into the handle mounting holes 4 and bent inward to be fixed. A second handle 5 is also connected to the outer side of the bottom plugging cap 2. The construction personnel can hold the first handle 3 with one hand to lift the charging tube 1, and hold the second handle 5 with the other hand to assist in lifting the charging tube 1, so that the charging tube 1 can be lifted more easily and the concrete pouring can be completed, which can save time and effort for the construction personnel when performing the operation.
[0021] This embodiment also includes that the second handle 5 is formed by connecting a plurality of wooden strips by bolts, the first handle 3 is formed by bending φ4 steel bars, and the loading tube 1 is a PVC tube with a diameter of 150 mm. Among them, the second handle 5 is designed as a wooden handle, which can assist the first handle 3 to quickly lift the loading tube 1 without increasing the weight of the overall utility model structure. The first handle 3 is designed to be bent by φ4 steel bars, which can further enhance the stability and safety during use. The loading tube 1 made of PVC tube is light in weight, low in cost, and easy to carry and turn over. In addition, the inner wall of the tube is smooth and has a small friction coefficient, which can prevent excessive contamination of the loading tube 1 during repeated use.
[0022] This embodiment also includes that a reinforcing bolt 6 is added to the connection between the bottom plugging cap 2 and the loading tube 1, and the angle of the beveled end of the loading tube 1 is 45 degrees. The bottom plugging cap 2 and the loading tube 1 are connected by glue. In order to further ensure the stability of the connection between them, a plurality of reinforcing bolts 6 are added around the connection between the bottom plugging cap 2 and the loading tube 1 for further tightening to improve safety during use. The angle of the beveled end of the loading tube 1 is optimally set to 45 degrees, which can not only quickly and conveniently dump the concrete in the loading tube 1, but also observe the state of the concrete during the pouring process in real time. The posture and method of pouring are adjusted in time according to the real-time observed state to minimize the spillage of concrete during pouring.
[0023] The method of using this embodiment is as follows:
[0024] The utility model provides an auxiliary tool for pouring a secondary structural column, which mainly includes a charging pipe 1, a bottom plugging cap 2, a first handle 3 and a second handle 5, wherein the charging pipe 1 adopts a PVC pipe with a diameter of 150 mm, the first handle 3 is formed by bending a φ4 steel bar, the second handle 5 is made of wood, and the reinforcing bolts 6 are self-tapping screws. When in use, one end of the PVC pipe is beveled at 45 degrees, and the other end is selected with a bottom plugging cap 2 of a size matching the PVC pipe, and the bottom plugging cap 2 is connected to the charging pipe 1 by glue. In order to ensure the stability of the bottom plugging cap 2, four self-tapping screws are also used to reinforce the bottom plugging cap 2 around it. On both sides of the charging pipe 1, symmetrical handle fixing holes 4 are opened 5 cm away from the edge of the beveled end of the charging pipe 1, and the φ4 steel bar is passed through the handle fixing hole 4. Then, the parts of the φ4 steel bar extending into the handle fixing hole 4 at both ends are bent inward twice for fixing, and the bending angle is 90 degrees. Finally, a second handle 5 is connected to the outside of the bottom plugging cap 2. The second handle 5 can be made of 1 cm thick and 3 cm wide wooden strips spliced together by self-tapping screws. The spliced second handle 5 is then connected to the bottom plugging cap 2 with self-tapping screws.
[0025] When the utility model is used, the construction worker needs to hold the second handle 5 at the end with one hand and the first handle 3 with the other hand to fill the interior of the charging tube 1 with concrete. At this time, the first handle 3 rotates to a natural vertical state. Then release the second handle 5 at the bottom of the charging tube 1, lift the charging tube 1 with only one hand and climb to the specified height, and hold the second handle 5 again with the other hand to lift it to the dustpan mouth at the top of the secondary structural column. Then lift the bottom of the charging tube 1 high above the dustpan mouth, and tilt the beveled end of the charging tube 1 toward the dustpan mouth. Watch the concrete slowly flow into the dustpan mouth along the beveled port of the charging tube 1, and control the speed of the concrete flowing into the dustpan mouth in real time to prevent the concrete from sliding too fast and overflowing to cause waste, until all the concrete in the charging tube 1 is poured out. This cycle is repeated until the dustpan mouth is filled with concrete and no longer sinks. It should be noted that before each use, the inside of the charging tube 1 needs to be moistened with water to prevent adhesion, and the charging tube 1 needs to be cleaned in time after use to prevent aggravation of pollution and affect the next use.
