Description
Technical Field
The invention relates to the field of civil engineering, in particular to a novel constructional column of a reinforced concrete structure.
Background
A constructional column is a building element that can effectively enhance the integrity, stability and load-bearing capacity of a building wall. The reinforced concrete constructional column is arranged in the wall body of the building, the upper end and the lower end of the constructional column are respectively connected with the floor slab or the ring beam, the hoop effect is achieved on the wall body, the wall body is broken and not scattered when being damaged under the action of external force, and particularly, the out-of-plane stability of the wall body is greatly enhanced, and the wall body can be effectively prevented from collapsing. Constructional columns are commonly used in architectural design to enhance the seismic performance of masonry walls.
The constructional column is arranged in the filling wall of the reinforced concrete structure, the lower end of the longitudinal bar of the conventional constructional column is generally lapped with the embedded bar of the floor or the pre-embedded bar of the floor, and the upper end of the longitudinal bar of the constructional column is generally lapped with the embedded bar of the lower surface of the upper floor. In addition to beam-free floors, beams are typically provided at the wall locations for beam-slab floors to support the weight of the wall. The construction of the column is provided with stirrups, which generally require the encryption of the stirrups at the two ends of the column.
The problems with conventional constructional columns are mainly the following:
(1) The upper ends of the longitudinal ribs of the constructional column are lapped with the planted ribs on the lower surface of the upper floor slab. The lower surface of the upper floor slab is planted with bars, which belongs to high-altitude operation, the bars at the beam bottom are dense, the bars are easy to meet the beam bars during drilling, the designed hole depth cannot be reached, and the planted bar glue is easy to flow downwards from the hole; when working aloft, the quality of the construction of workers is difficult to monitor and keep in charge. In actual engineering, most engineering constructional columns are unqualified in upper end bar planting, the connection between the upper ends of the constructional columns and the floor slab is unreliable, the constraint effect on the wall body is lost, a large number of constructional columns become furnishings virtually, and the quality common problems in the industry are caused.
In order to solve the problem, the method of embedding the reinforcing steel bars in the upper floor slab can replace the method of embedding the reinforcing steel bars in the slab bottom or the beam bottom, and the integrity of the template is destroyed because the embedded reinforcing steel bars need to be perforated in the template to pass through the reinforcing steel bars; the form is difficult to disassemble and is easy to damage. Therefore, in actual engineering, construction units are generally not willing to adopt.
(2) The connecting parts of the longitudinal ribs of the constructional column are positioned at the upper end and the lower end. Because the frame post is under the seismic action, both ends are destroyed easily, require the both ends stirrup of frame post to encrypt the setting, same reason, the regulation also requires the both ends stirrup of constructional column to encrypt the setting. The connecting parts of the longitudinal ribs of the constructional column are positioned at the upper end and the lower end, and are the parts which are easy to damage.
(3) When constructional columns are poured with concrete, the constructional columns are generally difficult to vibrate and compact.
Disclosure of Invention
The invention aims to provide a novel constructional column which is convenient to construct, reliable in quality and stable in connection between the constructional column and a floor slab and a beam.
In order to achieve the above purpose, the invention provides a novel constructional column which is positioned between an upper floor slab and a local floor slab, a concrete constructional column is arranged between the upper floor slab and the local floor slab, and constructional column longitudinal ribs are arranged in the concrete constructional column; the upper floor slab and the floor slab are embedded with sleeves at the positions of the concrete constructional columns, the upper ends of the constructional column longitudinal ribs continuously penetrate through the sleeves of the upper floor slab to the upper side of the upper floor slab, and the lower ends of the constructional column longitudinal ribs are connected with the upper ends of the constructional column longitudinal ribs of the next floor, which continuously penetrate through the sleeves of the floor slab. The floor slab comprises a beam-free floor slab and a beam slab type floor slab.
As a further improvement of the invention, the connecting position between the longitudinal ribs of the constructional column adjacent to the upper floor and the lower floor is positioned in the middle of the height of the concrete constructional column, so that the stirrup encryption area with two ends easy to damage is avoided, and the anchoring of the steel bars is reliable.
As a further improvement of the invention, the longitudinal ribs of the concrete constructional columns adjacent to the upper floor and the lower floor are connected by welding, so that each longitudinal rib of the concrete constructional column adjacent to the upper floor and the lower floor is essentially a through-length reinforcing steel bar.
As a further improvement of the invention, a gap is left between the inner wall of the sleeve and the longitudinal ribs of the constructional column, and the gap is filled with cement gel, so that the cement paste can be realized by grouting the sleeve, or cement paste naturally flows in when the constructional column is poured.
As a further improvement of the invention, the embedded sleeve is made of steel, and the adhesion and mechanical transmission of the sleeve and the steel bar are facilitated when the sleeve is grouted.
Advantageous effects
Compared with the prior art, the novel constructional column has the advantages that:
1. The upper end of the constructional column longitudinal bar continuously passes through the sleeve pipe of the upper floor plate upwards to enter the upper part of the upper floor plate, and the lower end of the constructional column longitudinal bar is connected with the upper end of the constructional column longitudinal bar of the next floor, which continuously passes through the sleeve pipe of the floor plate. The longitudinal ribs of the upper and lower constructional columns are continuously pulled through at the floor slab without joints; it can also be said that both ends of the column longitudinal ribs are anchored in the column concrete of the adjacent storey respectively. Therefore, the connection between the constructional column and the floor slab is more reliable, thereby ensuring the integrity and stability of the wall body.
2. The sleeve is embedded in the floor slab, so that the reinforcement bar is not needed, and the construction difficulty and the working strength are reduced.
3. The connecting position between the longitudinal bars of the adjacent concrete constructional columns of the upper floor and the lower floor is positioned in the middle of the height of the concrete constructional column, only one connecting joint is arranged, the stirrup encryption area with two ends easy to damage is avoided, and the steel bar anchoring is more reliable.
4. The longitudinal ribs of the concrete constructional columns adjacent to the upper floor and the lower floor are connected by welding, so that each longitudinal rib of the concrete constructional column adjacent to the upper floor and the lower floor is substantially a steel bar with a through length from top to bottom, and the drawknot action of the constructional column on the wall body cannot disappear even if the constructional column concrete is completely destroyed.
5. During construction, the vibrator can vibrate the part of the upper end of the constructional column longitudinal rib protruding out of the upper floor slab, so that the vibration of the constructional column longitudinal rib is transmitted to the concrete in the constructional column template, and the vibration effect on the concrete is realized.
