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

The invention relates to a method for making a shock-resistant and energy-dissipating framework by mixing resin concrete and reinforced concrete, which comprises the following six steps of: (1) reserving a position of the framework, at which a plastic hinge is possible to emerge, and pouring other parts of the framework according to an original construction design; (2) conserving the concrete poured in the framework for 14 days, carving burrs from the concrete around the reserved position, clearing gravels and dust off and cleaning the surface by acetone; (3) priming a layer with a thickness of 3 to 5mm by resin cement; (4) supporting a template at the reserved position; (5) preparing and pouring the resin concrete; and (6) standing and conserving the resin concrete framework over 10 DEG C for 72 hours and stripping a mold. Because the ultimate compression strain of the resin concrete is far greater than that of the ordinary concrete, the resin concrete is filled at an appropriate position in an ordinary reinforced concrete framework to form a mixed framework structure. Therefore, the framework can consume earthquake energy on the premise of not being damaged entirely. The method has a practical value in the technical field of civil engineering.

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...
