Description

Steel pre-column

This creation relates to a pre-assembled column and, in particular, to a pre-assembled column of steel bars having a total length of more than 6 meters and using spiral stirrups.

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 earthquake 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 a plurality of pre-assembled columns before use, but the structural strength will be reduced due to the non-integral structure. Furthermore, Because a large number of stirrups are used, and different types of stirrups cannot be used simultaneously in a pre-set column, the preparation of the stirrup becomes more cumbersome.

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, this creation will propose a pre-column of steel bars with a height of more than 6 meters and using spiral stirrups.

One of the scope of this creation is to provide a pre-column of steel bars. According to a specific embodiment of the present invention, the pre-assembled column of the artificial steel bar comprises a spiral stirrup, a plurality of first main tendons, a plurality of second main tendons, and a plurality of tendons. The spiral stirrup has one continuous spiral structure and has a first side and a second side corresponding to one of the first sides. Each of the first main ribs passes through and is fixed to the first side of the spiral stirrup. Each of the second main ribs passes through and is fixed to the second side of the spiral stirrup. Each of the two ends of each of the ribs has a first curved hook and a second curved hook, and the first curved hook is fastened to the corresponding first main rib, and the second curved hook is fastened to the corresponding first Two main tendons. Wherein the first main ribs and the second main ribs are parallel to each other and are each a steel bar integrally formed and having a length exceeding 6 meters.

The pre-assembled column of the steel bar further comprises a plurality of third main ribs, which are respectively parallel with the first main ribs and the second main ribs, and are respectively fixed on the first side or the second side corresponding to the spiral stirrups.

Wherein, the third main ribs are respectively fixed on the spiral stirrups by a welding method.

Furthermore, the spiral shape is square.

The angle of the first curved hook or the second curved hook is 135 degrees.

In addition, the first ribs fixed to the same first main rib are also fixed on the same second main rib.

Compared with the prior art, the pre-assembled column of the steel bar uses a spiral stirrup to surround the main structural shape, and supports and supports the hoop and the main rib through the stage and the iron pipe to maintain the appearance of the main rib and the stirrup. . Through the above method, a steel pre-column including a main rib having a length of more than 6 meters can be obtained, thereby eliminating the steps of continuation of a plurality of pre-columns in the high-length pre-column demand to reduce the break point. And strengthen the structural strength of the original steel pre-column.
