Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to a prefabricated frame column and steel bar integrated connector. Background Technology

[0002] Pouring is a crucial step in concrete construction. Before pouring, the formwork and reinforcing bars must be inspected to ensure their accurate and secure positioning. Pouring should be done in layers, with each layer generally not exceeding 1.25 times the length of the vibrator's effective section. Vibration is used to compact the concrete; immersion vibrators or plate vibrators are typically used. The vibration time should be until the concrete surface no longer settles, no more air bubbles appear, and a layer of cement paste begins to form.

[0003] The existing concrete columns require the construction of corresponding frames based on the height of the concrete during construction, which results in a significant waste of resources and generates a large amount of construction waste. Furthermore, the time wasted in setting up the formwork increases labor costs. Utility Model Content

By inserting the connecting assembly into the position between the first steel bar and the second steel bar, then the construction personnel erects the formwork between the position of the cement floor and the frame column, and then pours the concrete. At this time, attention should be paid to not pouring the concrete into the inside of the connecting assembly. When the concrete solidifies, the formwork is removed, and the slurry is injected into the inside of the connecting cylinder through the feeding end until it is completely filled, thereby completing the construction of the frame column. Through the construction method of the patent, the generation of construction waste can be effectively reduced, and the prefabricated frame column is fast to install on site. A large prefabricated column is hoisted by a crane and the like. A skilled construction team can install multiple columns in a day.

[0014] The driving group comprises a worm gear fixedly connected with the lead screw, a worm is meshingly connected to one side of the worm gear, the worm penetrates through and is rotatably connected with the mounting seat, and a connecting head is fixedly installed at the upper end of the worm;

[0015] In actual application, when the support rod needs to support the position of the frame column, the upper end of the support rod is installed on the outer wall of the frame column, then the support rod is installed at the position of the mounting seat according to needs, when the mounting seat is installed and the support rod needs to be fine-tuned in the inclined state, the worker first twists the threaded rod, so that the limiting columns at the lower ends of the lock plates are separated from the limiting holes, then a tool is used to rotate the connecting head, the connecting head drives the worm to rotate, the worm drives the worm gear to rotate, the worm gear drives the lead screw to rotate, then the sliding seat can move left and right, thereby fine-tuning the posture of the support rod;

[0016] The device limits the movement of the sliding seat by inserting the limiting column into the inside of the limiting hole, thereby avoiding damage to the screw rod screw teeth in the process of force.

[0017] The cooperation of the worm wheel and the worm in the driving group can not only change the operation direction, thereby facilitating the rotation of the connecting head by the staff, but also has the labor-saving effect.

[0018] Further, one end of the locking plate is fixedly provided with a guide rod, and the inside of the sliding seat is provided with a guide hole matched with the guide rod, so that the locking plate can only move up and down, and tilting of the locking plate is avoided.

[0020] 1、The patent is provided with a connecting assembly, which is inserted into the position between the first steel bar and the second steel bar, and then the staff erects the formwork between the cement floor and the frame column, and then pours concrete. At this time, attention should be paid to not pouring concrete into the inside of the connecting assembly. After the concrete solidifies, the formwork is removed, and the slurry is poured into the inside of the connecting cylinder through the feeding end until it is completely filled, thereby completing the construction of the frame column. The construction method of the patent can effectively reduce the generation of construction waste, and the prefabricated frame column is fast to install on site.
