Embodiment Construction

[0025] The present invention will be further described below with specific examples, and the resin concrete mixed reinforced concrete frame structure schematic diagram of anti-seismic energy dissipation of the present invention is shown in figure 1 shown.

[0026] The invention discloses a method for preparing an anti-seismic and energy-dissipating resin concrete mixed reinforced concrete frame. The resin concrete can be manually stirred or stirred by an ordinary concrete mixer according to the size of the reinforced concrete. Specific steps are as follows:

[0027] Step 1: After the frame steel bars are bound, reserve the beam-column joints and column roots of the frame structure (that is, the positions where plastic hinges may appear in the frame), and pour other parts according to the original construction design;

[0028] Step 2: After the concrete poured in the frame has been cured for 14 days, the stubble of the concrete around the reserved position is chiseled out (to ...

Abstract

A preparation method for an anti-seismic and energy-dissipating resin concrete mixed reinforced concrete frame, which has six major steps: 1. Reserve the position where plastic hinges may appear in the frame, and pour the rest of the frame according to the original construction design; 2. Pouring in the frame After curing the concrete for 14 days, chisel out stubble from the concrete around the reserved position, remove gravel and dust, and clean the surface with acetone; 3. Use resin cement as a base layer with a thickness of 3-5 mm; 4. The formwork is supported at the reserved position; 5. Prepare and pour resin concrete; 6. The resin concrete frame is maintained at an environment above 10 degrees Celsius, and the formwork is removed after 72 hours. The present invention utilizes the characteristic that the ultimate compressive strain of resin concrete is much greater than that of ordinary concrete, and fills resin concrete at an appropriate position in an ordinary reinforced concrete frame to form a mixed frame structure, so that the frame can consume earthquake energy without destroying the whole frame , it has practical value in the field of civil engineering technology.

Description

(1) Technical field [0001] The invention relates to a method for preparing an anti-seismic energy dissipation resin concrete mixed reinforced concrete frame, which is mainly used in the fields of buildings, bridges and water conservancy, and belongs to the technical field of civil engineering. (2) Background technology [0002] my country is an earthquake-prone country, and earthquake disasters have a huge destructive effect on building structures. The seismic design and reinforcement design of new structures are two important aspects of earthquake disaster mitigation, and they are also the research focus and hotspot of scholars at home and abroad. [0003] In recent years, the energy dissipation and shock absorption technology has been firstly applied to the seismic design and reinforcement of structures in my country. This technology is to place a certain number of energy dissipation equipment or set a certain number of energy dissipation components in the structure. At p...
