Description

Technical Field

[0001] The utility model relates to a pre-buried steel bar device for a structural column. Background Art

[0002] Concrete columns made in the specified parts of the walls of multi-story masonry houses according to the construction reinforcement and the construction sequence of first building the wall and then pouring the concrete columns are usually called concrete structural columns, or structural columns for short. In order to improve the seismic performance of the masonry structure of multi-story buildings, the specification requires that reinforced concrete columns should be set at appropriate parts of the masonry of the house and connected with the ring beam to jointly strengthen the stability of the building. This kind of reinforced concrete column is usually called a structural column. The structural column is not mainly used to bear vertical loads, but to resist shear force, earthquake and other lateral loads. Structural columns are usually set at the rest platform of the stairwell, at the intersection of the vertical and horizontal walls, at the corners of the wall, and at the middle part of the wall with a length of five meters. In recent years, in order to improve the bearing capacity or stability of the masonry structure without increasing the cross-sectional size, the structural columns in the wall are not only set at the corners and edges of the house wall, but also set in the middle part of the wall as needed, and the ring beam must be set in a closed state.

[0003] At present, the conventional method of structural columns is: after the main structure concrete is poured, the structural column is located at the bottom of the beam, and then a drill is used to drill holes, plant reinforcement, and then tie the reinforcement cage to form the structural column reinforcement. Then, the formwork is supported on the outside of the structural column steel and concrete is poured. The above method has low construction efficiency. Utility Model Content

Figure 4 A schematic diagram of the structure of another type of sealing cover for the hole where the embedded steel bars are placed in a structural column. Figure 5 This is a schematic diagram of the structure of another sealing cover for the hole where the embedded steel bars are placed in the structural column. Figure 1-Figure 5 As shown, the pre-embedded steel bar device for structural columns comprises: a concrete casting and forming template 1 for the bottom of the beam body, on which a pre-embedded steel bar placement hole 11 for the structural column is opened at the structural column setting position; a sealing cover 2 for the pre-embedded steel bar placement hole for the structural column, which is installed below the corresponding pre-embedded steel bar placement hole 11 for the structural column; and a structural column pre-embedded steel bar positioning hole system 3, which is opened on the sealing cover 2 for the pre-embedded steel bar placement hole for the structural column and cooperates with the corresponding pre-embedded steel bar 4 for the structural column.

[0028] The specific method of using the above-mentioned structural column pre-embedded steel bar device is as follows: first, before casting the beam, a structural column pre-embedded steel bar placement hole 11 is opened on the concrete casting and forming template 1 at the bottom of the beam body at the designed position of the structural column, and then the prefabricated structural column pre-embedded steel bar placement hole sealing cover 2 is installed below the corresponding structural column pre-embedded steel bar placement hole 11, and then the corresponding structural column pre-embedded steel bar 4 is inserted into each structural column pre-embedded steel bar positioning hole of the structural column pre-embedded steel bar positioning hole system 3, and the structural column pre-embedded steel bar 4 is tied and fixed to the steel bar in the beam, thereby completing the installation of the structural column pre-embedded steel bar. Thereafter, the concrete casting and forming of the beam is carried out, thereby anchoring the end of the structural column pre-embedded steel bar 4 in the beam. Afterwards, the structural column template is set up and the concrete casting and forming of the structural column is carried out.

[0029] Specifically, the inner side surface of the sealing cover 2 for placing the pre-embedded steel bars in the structural column has a recess 21, a positioning end surface 22 located around the recess 21, and an inclined surface 23 connecting the outer edge of the recess 21 and the inner edge of the positioning end surface 22. The positioning end surface 22 is in contact with the surface of the concrete casting template 1 at the bottom of the beam body. The inclined surface 23 forms a raised frustum at the bottom of the beam body cast by concrete. The positioning holes 3 for the pre-embedded steel bars in the structural column are arranged at intervals inside the outer edge of the recess. The inclined surface 23 forms a raised frustum at the bottom of the beam body cast by concrete, which facilitates the formation of a reliable mortise and tenon structure between the structural column and the bottom of the beam body, thereby improving the bearing capacity and stability of the connection between the structural column and the beam body.

[0030] Specifically, the positioning end surface 22 forms a flange, and the flange is connected to the concrete casting forming template at the bottom of the beam body through a connecting piece. The connecting piece is specifically a steel nail.

[0031] like Figure 2-Figure 5 As shown, according to the position and shape of the structural column, the outer edge of the recess forms a rectangular or L-shaped structure, and at least part of the structural column embedded steel bar positioning holes are arranged at the corners of the outer edge of the recess.

[0032] The above-mentioned structural column embedded steel bar device has the following advantages:

[0033] 1) Improve the construction efficiency of structural columns:

[0034] By pre-setting the holes for placing embedded steel bars of the structural columns, sealing covers for placing embedded steel bars of the structural columns and matching sealing covers and positioning hole systems on the concrete pouring and forming template at the bottom of the beam body, the steel bars of the structural columns can be accurately arranged in advance before pouring the beam body, thus avoiding the tedious process of manually tying steel bars on site in traditional construction and greatly improving the efficiency of structural column construction.

[0035] 2) Ensure accurate positioning of embedded steel bars in structural columns:

[0036] The structural column pre-embedded steel bar positioning holes set on the sealing cover of the structural column pre-embedded steel bar placement hole cooperate with the structural column pre-embedded steel bars to accurately fix the position and angle of the structural column pre-embedded steel bars, ensure the accuracy of the structural column steel bar layout, and reduce construction errors.

[0037] 3) Save time and labor, reduce costs:

[0038] The use of this structural column embedded steel bar device can reduce the workload of on-site manual steel bar tying, save construction time and labor costs, and improve construction economy. At the same time, the factory-prefabricated sealing cover and positioning hole system are highly accurate, which can reduce the cost of repairing common quality problems in structural column construction.
