Description

 Steel bar pre-column and manufacturing method thereof  

The present invention relates to a pre-column and a method of fabricating the same, and in particular to a pre-column of steel bars having a total length of more than 6 meters and a method of making the same.

The beam-column structure in the building is used to support the backbone of the whole building structure. In the general reinforced concrete design structure, in order to strengthen the structural shock resistance, the hoops are generally used to bundle the steel bars and concrete to make the steel bars. It can still be effectively combined with concrete during the earthquake.

Generally speaking, the reinforced concrete beam and column is composed of a plurality of main ribs and a plurality of stirrups to strengthen the surrounding force of the whole structure, and then a steel cage is completed, and then the steel cage is injected into the concrete to obtain the required reinforced concrete beam and column. The conventional practice is to erect the main ribs in the predetermined ground at the construction site, and then tie the stirrups one by one and bundle the plurality of main ribs, then fix the relative positions of the main ribs and the stirrups by lashing, and then pour the concrete into the concrete. Complete reinforced concrete beam and column operations. Another conventional practice is to first traverse the main ribs, then flatten the required stirrups one by one, then put them into the upper main ribs, and move the stirrups to the position, and then use the lashing method to fix the upper main ribs, and then the remaining main ribs. After the waistband is inserted into the stirrup, the tie is ligated, and finally the steel cage is erected and poured into the concrete after being predetermined. All of the above methods require a large amount of manpower to complete, and the latter method requires manual work to carry out the work, which is likely to cause personal injury and structural deformation.

Among them, the position of the stirrup is an important factor for the strength of a strengthened structure in the reinforced concrete beam-column structure, and it is also one of the important components of the effective earthquake resistance when the beam and column are damaged. At the same time, in order to strengthen the surrounding force of the stirrup, it is often An anchoring section is designed on the stirrup or the relative position of the main tendon and the stirrup is fixed by increasing the tendon. Therefore, the position and shape of the stirrup affect the structural safety of the building.

However, in the prior art, the staff members need to bundle the stirrups on the main ribs at the construction site. It is likely that the gap between the stirrups may be caused by the limitation of the high-altitude field area and the improper operation of the personnel. Wrong, and the resulting structural strength is not as expected.

Furthermore, with the change of architectural styles, in order to shorten the construction period requirements, reduce the construction cost and pollution, it is now a trend to pre-group the steel cages and then transport them to the required construction site.

The conventional pre-column is composed of a plurality of stirrups to be positioned and then the main tendons are inserted into the desired position, or the main tendons are placed in an array and then a plurality of stirrups are placed on the main tendons. Since the required stirrups and the main ribs can be prepared in advance and are easy to stack, the material preparation and assembly speed of the pre-column are more efficient than the conventional methods of construction, and the construction cost is also reduced. Its environmental pollution.

However, whether it is made in the form of a main rib or a stirrup, the structural composition of the pre-column is easy because the shape of the stirrup is slightly deformed, or the appearance of the main rib changes due to gravity, resulting in The height of the set of columns cannot be too long. When the required structural height is greater than the structural limit of the pre-column, it is necessary to use a splicer to combine multiple pre-assembled columns before use, but the structural strength will be reduced due to the non-integral structure.

It can be seen that there are still many shortcomings in the above-mentioned prior art, which is not a good design, and needs to be improved. In view of this, the present invention will propose a steel bar pre-column having a height of more than 6 meters and a manufacturing method thereof.

One aspect of the present invention is to provide a pre-column of steel bars. According to a specific embodiment of the present invention, the steel pre-assembled column of the present invention comprises a plurality of stirrups and a plurality of main bars. The stirrups are arranged at an axial interval, wherein each stirrup comprises a frame body, and a plurality of tie bars are staggered in the frame body and have a plurality of joint portions. Each of the main ribs passes through and is secured to the joints of the corresponding stirrups. Each of the main ribs is an integrally formed steel bar having a length of more than 6 meters.

Furthermore, the free end of one of the frames or the free end of one of the ribs is bent to form a hook, which is 135 degrees.

The frame and the ribs are formed by bending the steel bar integrally.

Furthermore, the stirrup can also be a combined stirrup.

In addition, the stirrups are made by leveling a flat tool.

Another aspect of the present invention is to provide a method of making a pre-column of steel bars. According to another embodiment of the present invention, the production of reinforced pre-column group of the present invention, comprising the following _steps: S _1: preparing an a plurality of stirrups, each stirrup which includes a housing, a casing with a staggered a plurality of ribs are pre-positioned with a plurality of joints, S ₂ : leveling the stirrups, S ₃ : preparing a stage having a plurality of grooves, and vertically setting the stirrups one by one On the grooves, S ₄ : preparing a plurality of main ribs, respectively guiding each of the main ribs through the joint portions of the corresponding stirrups, S ₅ : respectively fixing each main rib corresponding thereto The stirrups are used to create the steel pre-column.

After the frame 121 is wrapped around the main rib 14, the frame 121 is fixed by the tie 122. Wherein, the tendon 122 may have a U-shaped appearance or a lip-shaped appearance to surround the main rib 14 .

Moreover, the frame 121 can also be a combined frame, which is constructed by upper and lower frame synthesis or other means to achieve the benefit of combining components into large workpieces.

Of course, the combined stirrup can also be composed of a plurality of combined components including the frame 121 portion and the partial tie 122.

In addition, the stirrups 12 are made by leveling a flat tool.

In practical applications, because the stirrups 12 may be affected by storage placement or instability during the process, the position of each joint is slightly different, and the steel pre-column 1 is formed up to 6 meters or more. If there is a slight error in the joint, the main rib 14 cannot be effectively passed through the plurality of stirrups 12, or the stirrup 12 is deformed so that the steel pre-column 1 loses its original structural strength.

In addition, the main ribs 14 are respectively fixed to the joint portions of the corresponding stirrups 12 by a fixing manner, which is fixed in a welding manner or a binding manner.

Among them, the welding method is to use carbon dioxide cold welding.

Another aspect of the present invention is to provide a method of fabricating a steel bar pre-assembly column 1. According to another embodiment of the present invention, the method for manufacturing the steel pre-assembled column 1 of the present invention comprises the following steps: S ₁ : preparing a plurality of stirrups 12, wherein each stirrup 12 comprises a frame 121, a frame A plurality of ribs 122 are staggered in the body 121 and a plurality of joints are pre-set, S ₂ : leveling the stirrups 12, S ₃ : preparing a stage having a plurality of grooves, and preparing the same The stirrups 12 are respectively vertically disposed on the grooves, and S ₄ : preparing a plurality of main ribs 14 for guiding each of the main ribs 14 respectively through the joint portions of the stirrups 12 corresponding thereto. S ₅ : fixing each of the main ribs 14 and the corresponding stirrups 12 corresponding thereto, thereby generating the steel pre-assembled columns 1 . Each of the main ribs 14 is an integrally formed steel bar having a length of more than 6 meters.

The frame body 121 and the rib 122 are formed by bending the steel bar integrally.

Furthermore, the stirrup 12 can also be a combined stirrup.

In practical applications, a steel bar may be bent into a shape of a stirrup 12 including a frame body 121 and a tie bar 122, or a separate frame body 121 and a plurality of tie bars 122 may be combined into a desired stirrup. 12.

Furthermore, the free end of one of the frames 121 or the free end of one of the ribs 122 is bent to form a bent hook 123, which has a 135 degree angle.

In practical applications, the curved hook 123 is formed as an anchoring section, and when the reinforcing steel pre-column 1 is poured into the concrete to obtain a reinforced concrete column, the reinforcing steel pre-assembled column 1 can be kept in a bundled force. In addition, there may be more than one curved hook 123 in a stirrup 12, and the other curved hooks 123 may also be formed by a 90 degree angle or other forms of corners.
