Description

Technical Field

[0001] This utility model relates to the field of building construction engineering, and in particular to a comprehensive construction tool for preventing root rot of tall frame columns. Background Technology

[0002] The base of existing high-support frame columns is prone to root rot, and the main reasons for this are as follows:

[0003] (1) The excessive free fall height of the concrete during the pouring of the tall frame column makes it prone to segregation. In addition, the blocking effect of the stirrups of the frame column will slow down the falling speed of the stones in the concrete, which will destroy the concrete mix ratio. Furthermore, the grout in the early stage of the concrete is prone to adhere to the stirrups inside the tall frame column, which further aggravates the segregation of the bottom concrete, causing the tall frame column to rot at the root.

[0004] (2) The concrete at the bottom of tall frame columns is difficult to vibrate or not vibrated properly, resulting in uneven vibration of the stones and grout at the bottom of the tall frame columns, which in turn leads to root rot.

[0005] (3) The gaps at the base of the formwork of the tall frame column were not sealed properly, which led to grout leakage and caused the tall frame column to rot at the base. Utility Model Content

[0006] One of the purposes of this utility model is to provide a comprehensive construction tool for preventing root rot in tall frame columns, which aims to solve the problem of root rot easily occurring at the bottom of existing tall frame columns.

[0007] The technical solution of this application is:

[0008] A comprehensive construction tool for preventing root rot in tall frame columns is used to be installed inside the cavity of tall frame columns. It includes a PVC delivery pipe, a circular steel bar, fixed long bars, and fixed short bars. The circular steel bar is provided on the inner side of the upper end of the PVC delivery pipe. Multiple fixed long bars and multiple fixed short bars are provided at intervals on the periphery of the circular steel bar. The fixed short bars and fixed long bars all extend out of the outer side of the PVC delivery pipe.

[0009] As one technical solution of this application, the fixed long bar and the fixed short bar are arranged alternately on the periphery of the circular steel bar.

[0010] As one technical solution of this application, the fixed long bar includes two bars, which are symmetrically arranged relative to the circular steel bar.

[0011] As one technical solution of this application, the fixed long bar includes a first connecting bar, a second connecting bar and a third connecting bar that are integrally formed and connected vertically in sequence. The first connecting bar is connected to the circular steel bar, and the first connecting bar and the third connecting bar are both on the same side of the second connecting bar.

[0012] As one technical solution of this application, the length of the first connecting rib is greater than the length of the third connecting rib.

[0013] As one technical solution of this application, the fixed short bar includes two bars, which are symmetrically arranged relative to the circular steel bar.

[0014] As one technical solution of this application, the circular steel bar is detachably provided with a feed funnel for pouring concrete.

[0015] As one technical solution of this application, a template is installed on the periphery of the tall frame column, and a vibration port is reserved at the lower part of the template for vibrating the concrete at the bottom of the inner cavity of the tall frame column.

[0016] As one technical solution of this application, a double-sided adhesive layer is pasted between the lower part of the template and the concrete base plate of the tall frame column, and a cement mortar layer is provided on the outer side of the template.

[0017] As one technical solution of this application, the height h of the tall frame column is 5-8 meters; the length of the PVC conveying pipe is h-1 meter, and the diameter is smaller than the size of the limiting cavity formed by the transverse stirrups and longitudinal stirrups at the most central position in the inner cavity of the tall frame column.

[0018] The beneficial effects of this utility model are:

[0019] This tool is a prefabricated, integrated structure made of PVC delivery pipes, circular reinforcing bars, fixed long bars, and fixed short bars. It is then lowered slowly from above the tall frame column containing concrete through the internal stirrups using a tower crane. This creates a chute within the column, allowing the concrete to fall slowly and effectively reducing its descent speed to prevent segregation. It also effectively addresses the problem of segregation at the base of the frame column caused by excessive free fall during concrete pouring, which can lead to root rot. Therefore, this device is simple in structure, easy to use, and effectively solves the problem of root rot at the base of tall frame columns. Attached Figure Description

[0034] Example:

[0035] Please refer to Figure 1 (Refer to) Figures 2 to 5This application provides an auxiliary tool for comprehensive construction of tall frame columns to prevent root rot. It is installed inside the cavity of the tall frame column 1 and includes a PVC delivery pipe 3, a circular reinforcing bar 4, fixed long bars 5, and fixed short bars 6. The PVC delivery pipe 3 has a circular reinforcing bar 4 on its inner upper end. Multiple fixed long bars 5 and multiple fixed short bars 6 are spaced apart on the periphery of the circular reinforcing bar 4. Furthermore, the fixed short bars 6 and fixed long bars 5 extend outwards from the outside of the PVC delivery pipe 3, and are alternately arranged on the periphery of the circular reinforcing bar 4. The fixed long bars 5 and fixed short bars 6 support and fix the PVC delivery pipe 3 during hoisting. After the PVC delivery pipe 3 is hoisted by a tower crane and placed into the stirrups inside the tall frame column 1 to be poured concrete, the two fixed long bars 5 can be supported by square steel or timber to fix the PVC delivery pipe 3.

[0036] It should be noted that in this embodiment, two fixed long reinforcing bars 5 are used, and they are symmetrically arranged with respect to the circular reinforcing bar 4. In other embodiments, the number and shape of the fixed long reinforcing bars 5 can be adapted to actual construction needs and are not limited to the design method in this embodiment.

[0037] Furthermore, the fixed long bar 5 includes a first connecting bar 7, a second connecting bar 8, and a third connecting bar 9, which are integrally formed and vertically connected in sequence. The first connecting bar 7 is connected to the circular steel bar 4 and is vertically arranged. The first connecting bar 7 and the third connecting bar 9 are both located on the same side of the second connecting bar 8 and are both horizontally arranged. Moreover, the length of the first connecting bar 7 is greater than the length of the third connecting bar 9.

[0038] In this embodiment, two short fixing bars 6 are used, and they are symmetrically arranged relative to the circular reinforcing bar 4. In other embodiments, the number and shape of the short fixing bars 6 can be adapted to actual construction needs and are not limited to the design method in this embodiment.

[0039] In addition, a feed hopper 10 for pouring concrete is detachably provided on the circular steel bar 4, through which the concrete to be poured enters the inner cavity of the tall frame column 1.

[0040] It should be noted that a formwork 2 is installed on the perimeter wall of the tall frame column 1. A vibration port 11 is reserved at the lower part of the formwork 2 for vibrating the concrete at the bottom of the inner cavity of the tall frame column 1. The reserved vibration port 11 is located approximately 1 meter away from the bottom slab on one side of the formwork 2, and is 50cm x 50cm in size. This facilitates enhanced vibration of the concrete at the bottom of the frame column during concrete pouring, preventing root rot caused by insufficient vibration. The reserved vibration port 11 is sealed tightly just before the concrete is poured to the level of the vibration port 11. A double-sided adhesive layer 12 is adhered between the lower part of the formwork 2 and the concrete bottom slab of the tall frame column 1. Cement mortar is applied to the outer side of the formwork 2 and compacted to form a cement mortar layer 13. This measure effectively prevents grout leakage at the bottom of the formwork 2.

[0041] It should be noted that the height h of the tall frame column 1 is 5-8 meters; the length of the PVC conveying pipe 3 is h-1 meter, and the diameter of the PVC conveying pipe 3 is 150 mm. This diameter is smaller than the size of the limiting cavity formed by the transverse and longitudinal stirrups at the very center of the inner cavity of the tall frame column 1. Specifically, the size of the limiting cavity is 180 mm × 180 mm, allowing the PVC conveying pipe 3 to be smoothly placed into the limiting cavity of the tall frame column 1 to be poured concrete. For example, when the height h of the tall frame column 1 to be poured concrete is 1 meter, the length of the PVC conveying pipe 3 is h-1, meaning the free fall height of the concrete is 1 meter. This effectively prevents segregation caused by excessive free fall height during concrete pouring.

[0042] The construction process of the tall frame column 1 is as follows:

[0043] First, double-sided adhesive layer 12 is pasted between the lower part of the formwork 2, which is closed around the tall frame column 1, and the concrete base slab of the tall frame column 1. Then, cement mortar is applied to the outer perimeter of the formwork 2 and compacted to form a cement mortar layer 13. Next, a 50cm high vibration port 11 is pre-positioned on one side of the formwork 2, about 1m away from the base slab of the tall frame column 1. The PVC conveying pipe 3 is hoisted by a tower crane to the top of the tall frame column 1 to be poured with concrete, and slowly lowered from the stirrups inside the tall frame column 1. The concrete is fed through the feed funnel 10 and the PVC conveying pipe 3. The PVC delivery pipe 3 is poured to the bottom of the tall frame column 1, which effectively reduces the height of the concrete falling freely. The PVC delivery pipe 3 acts as a chute, which can further reduce the falling speed of the concrete and prevent segregation. During the concrete pouring process, the concrete at the bottom of the tall frame column 1 is strengthened by vibrating through the vibrating port 11. Finally, when the concrete is about to be poured to the vibrating port 11, the reserved vibrating port 11 is sealed tightly. This can effectively solve the problem of segregation during the concrete pouring process of the tall frame column 1 under the high formwork system, which can cause the bottom of the frame column to rot.

[0044] In summary, this tool integrates the PVC delivery pipe 3 with the circular steel bar 4, fixed long bars 5, and fixed short bars 6 into a prefabricated structure. Using a tower crane, it is slowly lowered from above the tall frame column 1 (to be poured concrete) through the internal stirrups of the column. This creates a chute within the column, allowing the concrete to fall slowly. This effectively reduces the falling speed of the concrete and prevents segregation. It also effectively addresses the problem of segregation at the base of the frame column caused by excessive free fall during concrete pouring. Therefore, this device is simple in structure, easy to use, and effectively solves the problem of root rot at the base of tall frame columns 1.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
