Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction column pouring technology, and particularly relates to a guide pouring construction column concrete construction method. BACKGROUND

[0002] The construction column is formed by construction on the wall that has been constructed, and is a key component of the partition wall project and plays a role in enhancing the overall stability of the building. The traditional construction method is to install a construction column steel bar or a steel reinforcement cage at the position where the construction column needs to be constructed, then install a formwork on both sides of the wall, so that the formwork is attached to the wall surface, and then a pouring opening is formed at the top end of the formwork to realize the pouring of the concrete in the construction column (for example, as shown in Figs. Figure 4 、 Figure 5 ).

[0003] For the construction column concrete pouring process, it is usually necessary to pour concrete into the formwork from the top end of the construction column. However, since the top of the construction column is already attached to the floor slab, it is difficult to pour concrete into the construction column, and even the compactness of the concrete near the top of the construction column is affected, which affects the overall quality of the construction column.

[0004] In view of this, the prior art has designed a concrete guide structure for the construction column pouring process in order to facilitate the pouring of concrete into the construction column formwork and to reduce the difficulty of pouring concrete into the construction column formwork. For example, patent application No. 201910463099.1 discloses a switchable pouring structure at the pouring opening at the upper end of the construction column formwork. Through the arrangement of the pouring structure, the concrete can enter the construction column formwork under the action of the movable plate-two side plates, and the concrete at the top of the construction column can be filled and compacted through the adjustable action of the movable plate, thereby reducing the difficulty of pouring concrete into the construction column formwork. However, the pouring structure of the device structure does not have an arc surface structure, resulting in poor concrete guide effect.

[0005] For another example, patent No. 201621246827.1 discloses a construction column pouring formwork based on a standard section combination, which includes a pouring hopper. The pouring hopper structure is used to realize the function of guiding the concrete into the construction column formwork, thereby reducing the difficulty of pouring concrete into the construction column formwork from the top end of the construction column formwork. However, the design of the hopper gate structure is inserted from the top, and the top is often occupied by the floor (as shown in Figs. Figure 3 or Figure 4 ), which makes it difficult to open the hopper gate, and the application range of the device is limited.

[0006] For example: Patent No. 202111282605.0 discloses a adjustable construction column pouring port template structure, including a template and a construction column pouring port located at the top edge of the template, the outer side of the template and located on both sides of the construction column pouring port is fixed with a fixed plate, the two fixed plates are provided with a movable plate, the movable plate is hinged to the bottom edge of the construction column pouring port, the movable plate can be shielded by rotating, the outer side of the movable plate is slidably connected with a supporting plug, the supporting plug can be inserted into the supporting hole when the movable plate is rotated outward, the fixed plug is slidably connected to the movable plate, when the movable plate is rotated to shield the construction column pouring port, the fixed plug can be extended outside the bottom edge of the movable plate and abutted on the outer side of the template to limit the outward rotation of the movable plate, so as to facilitate the pouring of concrete and reduce the pouring difficulty, but the pouring structure of the device structure does not have an arc surface structure, resulting in poor concrete flow guiding effect.

[0007] Based on the above technical defects, the research team combines the actual construction of the construction column, and aims at the defects of the flow guiding device in the construction column concrete pouring process, in order to reduce the difficulty of concrete pouring, enhance the concrete flow guiding effect, and improve the concrete pouring efficiency, so as to shorten the construction period of the construction column concrete pouring and reduce the construction cost. Based on the purpose, the flow guiding device structure for construction column concrete pouring is researched, and the flow guiding device structure as shown in Figures 2 to 12 is provided to solve the above technical problems.

[0008] However, whether it is the construction column pouring template structure in the prior art or the flow guiding device structure as shown in Figures 2 to 12 , there are still some problems. After the construction column concrete pouring is completed, part of the concrete will accumulate in the flow guiding groove, so that the construction column concrete solidifies into a whole and protrudes at the position of the flow guiding device structure, and then the protruding part needs to be cut, which causes the construction period of the construction column to be long, the cutting difficulty to be high, and the cost to be high.

DETAILED DESCRIPTION

[0050] In order to facilitate those skilled in the art to correctly understand the present invention and enable those skilled in the art to fully understand the technical content of the present invention, the technical solution of the present invention is further explained below in conjunction with specific implementation methods, but this explanation does not limit the scope of protection required for the present invention. The scope of protection of the present invention by those skilled in the art cannot be limited to the following explanations. Any equivalent replacement or change made by any those skilled in the art or persons familiar with the technology in this field, on the basis of the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

[0051] In the prior art, the construction of structural columns is usually as follows Figure 4 and Figure 5As shown, the construction column structure is provided on the wall body 8, the construction column pouring position is reserved through the wall body 8 masonry process, and the construction column column bar 10 (steel reinforcement cage) and the like are provided on the construction column pouring position, then after the wall body 8 masonry is completed, the construction column formwork 4 is used to adhere and close on both sides of the wall body 8, and the pouring opening 5 (usually a square, rectangular structure, etc.) for pouring concrete is opened at the top end of the construction column formwork 4 on one side, so as to facilitate the construction column concrete pouring; however, the top of the construction column is often affected by the slab 7, which leads to the difficulty of the top pouring concrete construction, and often leads to the large concrete pouring loss rate, and when the concrete in the construction column is poured to the top, the opening of the pouring opening often leads to the difficulty of the concrete pouring filling to the surface of the slab 7, even if it can be close, but the local density is poor, which leads to the poor overall quality of the construction column. Therefore, in the construction column concrete pouring process, the installation of the flow guide device capable of pouring concrete from the pouring opening 5 on the construction column formwork 4 has been widely studied, but there are: the pouring opening 5 is opened into a square or rectangular structure, so that the flow guide structure part in the flow guide device is square, which makes the concrete difficult to flow into the center of the construction column, and dispersed in the construction column formwork, which leads to the poor density of the center of the construction column; at the same time, due to the unreasonable design of the flow guide structure part, the concrete sliding efficiency is poor, which affects the construction efficiency.

[0053] In use, one side of the construction column template 4 is selected to have a pouring opening 5 at the top end, and a plurality of mounting holes 6 are provided along the pouring opening 5 to form a structure as shown in Figure 3 The construction column template 4 is installed on both sides of the wall 8 at the predetermined position of the construction column and is fastened. A template (wooden board, steel plate, etc.) with a width less than that of the construction column template 4 is used as the mounting plate 1, and an opening corresponding to and matching the pouring opening 5 is provided on the mounting plate 1. An arc-shaped flow guide groove 2 is cut and bent from a steel plate or an aluminum plate, which can cover the pouring opening 5, and is used as the flow guide groove 2.

[0055] As shown in Figure 8 , in some embodiments, the mounting hole 6 is provided with an internal thread that can match the mounting bolt 9. The positioning hole 3 is provided with an internal thread that can match the mounting bolt 9. The mounting bolt 9 is twisted into the positioning hole 3 on the mounting plate 1, and then is twisted into the mounting hole 6 through the positioning hole 3, and the stable connection between the construction column template 4 and the mounting plate 1 is achieved, so that a smooth surface can be formed on the side of the construction column template 4 close to the construction column.

[0059] As shown in Figure 11 and Figure 12 , in some embodiments, the hanging piece 12 is provided with a piece hole 13 that can match the installation bolt 9. During installation, the installation bolt 9 is twisted into the installation hole 6 from the positioning hole 3 and connected by extending into the piece hole 13 through the installation hole 6. In some embodiments, the piece hole 13 is provided with an internal thread that can match the installation bolt 9 to enhance the integrity of the connection.

This helps to enhance the stability of the connection between the installation plate 1 and the construction column formwork 4.

[0061] In some embodiments, the installation plate 1 is provided with a hanging piece 12 on the side surface near the top end on one side of the construction column formwork 4 (as shown in Figures 9-14 ), the installation plate 1 is integrally formed with an extension plate 19 at the bottom end, the extension plate 19 and the construction column formwork 4 are provided with rear disassembly holes 23 at corresponding positions, the rear disassembly holes 23 are provided with rear disassembly bolts 18, and the rear disassembly bolts 18 connect the extension plate 19 and the construction column formwork 4 into a whole (as shown in Figures 13-19The installation plate 1 is stably connected with the constructional column template 4 after the installation bolt 9 is removed, the concrete inserted into the flow guide groove 2 from left to right or from right to left is facilitated, the construction period is shortened, and the construction difficulty is reduced.

In use, after the concrete is poured into the constructional column template 4 and until the concrete is poured to fill the flow guide groove 2, the inserted and cut plate 17 (a steel plate with a thickness of 0.5 mm, 1 mm, 2 mm, or the like) is inserted through the inserted and cut groove 16 from left to right as shown in Figure 15 to form a structure as shown in Figure 16 , which can cut the concrete poured into the flow guide groove 2, and after the concrete in the constructional column is solidified and cured, the constructional column template 4 is directly removed, so that the top end of the constructional column is flat on the surface side of the wall 8, the cutting process after the concrete in the constructional column is solidified is avoided, and the cutting difficulty is reduced.

[0063] As shown in Figures 15 to 19 In some embodiments, the constructional column template 4 is provided with a second fixing hole 22 along the pouring opening 5, and the second fixing hole 22 is located at an end of the positioning hole 3 away from the pouring opening 5; the inserted and cut plate 17 is provided with a first fixing hole 21, the first fixing hole 21 is provided corresponding to the second fixing hole 22, and the second fixing hole 22 and the first fixing hole 21 can be matched and connected with the installation bolt 9.

After the concrete in the constructional column is poured, the installation bolt 9 is screwed out, the inserted and cut plate 17 is pushed to the right, the inserted and cut plate 17 cuts the concrete and passes out from the right end of the inserted and cut groove 16, and after the first fixing hole 21 at the right end of the inserted and cut plate 17 is aligned with the second fixing hole 22, the first fixing hole 21 and the second fixing hole 22 are screwed and connected with the installation bolt 9 to form a structure as shown in Figure 15 .
