Detailed Description
As shown in fig. 1 to 3, the utility model relates to a prefabricated strong and weak current box concrete frame, including concrete frame main part and pre-buried two-layer reinforcing bar 3 in concrete frame main part inboard.
The whole rectangle frame column structure that is of concrete frame main part, concrete frame main part include two relative long frames 2 that set up and two relative short frames 1 that set up, but the surperficial undercut at 2 middle parts of one of them long frame is equipped with wire casing 5 that the power supply line passed, and the electric wire in the strong and weak current case can be worn out prefabricated strong and weak current case concrete frame by wire casing 5 during the fitment. Each layer of steel bars 3 extends inside the two long frames 2 and the two short frames 1 respectively. Each layer of steel bar 3 is an integral steel bar which continuously penetrates through the two long frames 2 and the two short frames 1, the integral steel bar is formed by bending one steel bar and is connected end to end, and the integral outline of the integral steel bar is rectangular, as shown in fig. 3.
Be equipped with the isolating device that can prevent that different layer reinforcing bars 3 from touching each other between two-layer reinforcing bar 3, isolating device is also pre-buried in the concrete frame main part. In this embodiment, the isolation device is a square precast concrete pad 4, and the precast concrete pads 4 are respectively arranged between two layers of the steel bars 3 at intervals. During construction, the precast concrete cushion blocks 4 are respectively arranged between the turning positions of the reinforcing steel bars at the four corners of the two layers of reinforcing steel bars 3, so that the precast concrete cushion blocks 4 can effectively isolate the two layers of reinforcing steel bars 3, concrete is poured into a precast strong and weak electric box concrete frame mold (not shown in the figure), and a precast strong and weak electric box concrete frame can be obtained after the concrete is condensed. Two-layer reinforcing bar 3 is by pouring the concrete after keeping apart, and each layer of reinforcing bar 3 can effectually contact with the concrete, does not have some reinforcing bar surface and does not contact the department to the concrete, and the easy oxidation influences the atress of prefabricated strong and weak electric box concrete frame. The precast concrete pad 4 is a pad that is molded by casting concrete in advance, and the precast concrete pad 4 may also be directly purchased in the market.
The construction comprises the following steps: 1. building the prefabricated strong and weak electric box concrete frame finished product on the position of a masonry electric box at the position where the strong and weak electric box is reserved, wherein the mortar control is consistent with the masonry engineering requirement, and the width and the thickness are controlled to be about 10 mm; 2. checking that the embedded pipeline at the position of the connecting pipeline corresponds to the reserved position of the electrical box niche; 3. when the prefabricated strong and weak electric box concrete frame is installed, a horizontal through line is pulled, the vertical verticality is controlled by a horizontal ruler, and the horizontal, horizontal and vertical directions and the correct position are ensured; 4. technical rechecking is carried out in time in the installation and forming process, the displacement and the stability of the concrete frame of the prefabricated strong and weak electric box need to be monitored in the concrete pouring process, and once the displacement is generated, the displacement is adjusted and reinforced in time.
The above embodiments are only preferred embodiments of the present invention, the structure of the present invention is not limited to the forms illustrated in the above embodiments, and any modifications, equivalent substitutions, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
