Problems solved by technology

[0002] The existing cover beam construction device, the existing reinforced concrete cover beam construction device on the reinforced concrete column basically has a support construction. When there is a support construction, there are high requirements for the foundation and high requirements for the support. When using no support construction, it is generally Add hoops to the column, put I-beams on the hoops, sometimes the hoops will slide down, which will cause the formwork to shift, so the safety and stability of the construction device without brackets is not good, and the existing construction method without brackets It is often necessary to weld threaded steel bars and I-beams to ensure stability, the process is complicated, and it is troublesome to remove

Embodiment 1

[0030] see Figure 1 to Figure 4 , a reinforced concrete cover beam on a reinforced concrete column without a support construction method, comprising the following steps:

[0031] (1) Reserving holes 001 on both sides of the reinforced concrete column 002, the direction of the holes 001 is perpendicular to the direction of the roadbed, and threaded steel bars 1 are passed through the holes 001;

[0032] (2) A rack type support block 2 is provided at both ends of the threaded steel bar 1, and the middle part of the rack type support block 3 is provided with an internal thread, and the rack type support block 2 is supported by rotating the rack type support block 2. The internal thread of the block 2 is connected with the threaded steel bar 1, and the threaded steel bar 1 is fixed on the reinforced concrete column 002 and the end of the rack-type support block 2 with the rack faces upward, and the rack-type support block 2 and the threaded steel bar are passed through The conne...

Embodiment 2

[0041]The present invention also provides a construction device for a reinforced concrete cap beam without a support on a reinforced concrete column, comprising a threaded steel bar 1, a rack-type support block 2, an I-beam 3 and a plurality of hydraulic ejector rods 4, the two ends of the threaded steel bar 1 All are equipped with a rack-type support block 2, the middle part of the rack-type support block 2 is provided with an internal thread, the rack-type support block 2 is connected with the threaded steel bar 1 through the internal thread, and through the rack-type The connection between the support block 2 and the threaded steel bar 1 can fix the threaded steel bar 1 on the reinforced concrete column 002, and prevent the said threaded steel bar 1 from rotating in the reserved hole 001 of the reinforced concrete column 002, so as to avoid safety problems. One end of the rack type support block 2 is provided with a hydraulic ejector rod 4, and the bottom of one end of the I...

Abstract

The reinforced concrete cover beam on the reinforced concrete column has no support construction method. Holes are reserved on both sides of the reinforced concrete column, and the threaded steel bars are passed through the holes; rack-type support blocks are arranged at both ends of the threaded steel bars. The middle part of the rack-type support block is provided with an internal thread, and the internal thread of the rack-type support block is connected with the threaded steel bar; a hydraulic ejector rod is arranged at one end of the rack-type support block, and the hydraulic ejector rod is passed through the The first through hole is connected to the top of the I-beam, a bottom formwork is laid on the top of the I-beam, side formwork is erected around the bottom formwork, and then concrete is poured. Remove the side formwork, bottom formwork, hydraulic ejector rod, I-beam, rack-type support block, threaded steel bar, and complete the construction of the reinforced concrete cover beam on the reinforced concrete column without support. It can prevent the rotation of the threaded steel bar, prevent the I-beam from shifting and cause safety hazards, has good structural stability, is easy to disassemble, and has a high reuse rate, which can reduce construction costs.

Description
