Description

Technical Field

[0001] The utility model relates to the field of structural beam reinforcement fixing, in particular to an ultra-wide and ultra-high structural beam reinforcement fixing skeleton structure. Background Art

[0002] In the construction of reinforced concrete structures, as the span of the structure continues to increase, a large number of ultra-wide and ultra-high structural beams appear. At the same time, the number of beam reinforcements has also increased significantly and is relatively complex, often placing high demands on the construction quality of the beams. Combined with the construction site, it was found that due to the inadequate control of the installation and binding of the reinforcement and the large deviation of the beam clearance cross-sectional dimensions, the beam reinforcement arrangement could not meet the standard spacing requirements, and a large number of struts were used in the beam formwork. At the same time, due to the large and dense beam reinforcement, the reinforcement binding is dense, and all operations are carried out at high altitude, especially the reinforcement of the middle structural beam is more dense, which makes it difficult to ensure the quality of the reinforcement binding construction of the structural beam, affecting the quality of the structural beam reinforcement and concrete construction. Usually, the construction of structural beam reinforcement uses steel pipes to set up temporary reinforcement supports. After the installation and binding are completed, the temporary supports are removed. The process requires sufficient hoisting working surface and lifting equipment, which is relatively difficult to construct. Therefore, the construction of ultra-wide and ultra-high structural beams has greatly increased the construction difficulty. Utility Model Content

[0028] Further, the working principle of the utility model is:

[0029] 1) Make steel skeleton

[0030] A rectangular or square steel frame is manufactured according to the cross-sectional dimensions of the structural beam 1, using HRB400 steel bars with a diameter of ≥20 mm as raw material. The steel frame is welded into a steel frame according to the number and number of rows of the upper distributed steel bars 2 and the lower distributed steel bars 3 of the structural beam 1. The frame comprises a frame body 51 and upper and lower positioning steel bars. The width of the frame body 51 is made consistent with the cross-sectional dimensions of the structural beam 1, so as to control the thickness of the beam side cover 7 and the beam bottom cover 8, and to serve as internal support for the formwork 9.

[0031] 2) Set up the steel skeleton

[0032] After the template 9 at the bottom of the beam is installed, begin to arrange the steel bars and the steel skeleton on the template 9 at the bottom of the beam. When tying the frame beam reinforcement, set the steel skeleton inside the frame beam reinforcement at a spacing of 3m. Install and fix the processed steel skeleton along the longitudinal direction of the structural beam 1. Fix the upper distributed steel bars 2 and the lower distributed steel bars 3 of the structural beam 1 to the steel skeleton by electric welding. Ensure that the upper distributed steel bars 2 and the lower distributed steel bars 3 are stable and firm to the steel skeleton. At the same time, adjust the position of the steel skeleton to ensure that it is in the center of the beam structure section.

[0033] 3) Installation and binding of main reinforcement of frame structure beam 1

[0034] Arrange the beam corner reinforcement according to the beam reinforcement diagram, then install the beam stirrups in sections along the length of the frame, thread the upper and lower main reinforcements of the frame beam in sequence, and then tie and secure the beam reinforcement; finally, install the torsion reinforcement or structural reinforcement on the beam side as waist reinforcement 4;

[0035] 4) Installation and fixing of structural beam 1 formwork 9

[0036] The steel skeleton is used as the internal support of the template 9, thereby accurately controlling the clearance size of the template 9 and ensuring the structural size of the frame beam;

[0037] 5) Concrete pouring of structural beam 1

[0038] The concrete of the frame beam is vibrated twice, and vibrated once more before the concrete begins to set to enhance the density of the concrete and reduce shrinkage. During the pouring process, a special person is assigned to watch over the site to prevent problems such as displacement and deformation of the skeleton, which should be repaired and handled in time. After pouring, the concrete maintenance of the beam is strengthened. In addition to watering the top of the beam, water should also be poured on the side of the beam. Before the full-floor load-bearing scaffolding is removed, the beam is watered and maintained with a high-pressure water gun, and the demoulding time of the beam side formwork is delayed.

Any changes or substitutions that a person skilled in the art can conceive within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
