Temperature joint structure capable of transmitting earthquake force

Abstract

The invention discloses a temperature joint structure capable of transmitting an earthquake force. The temperature joint structure capable of transmitting the earthquake force is that a force transmission part is arranged in a temperature joint; the force transmission component comprises an outer box body which is full of liquid; the left side surface and the right side surface of the outer box body are connected with a concrete component; the rest side surfaces of the outer box body are equipped with folding line plates or arc-shaped line plates; a liquid inlet / outlet hole is formed in the upper side surface of the outer box body; a liquid storing box is arranged on the outer box body; liquid which covers at least the bottom surface fills in the liquid storing box; another liquid inlet / outlet hole which communicates with the outer box body is formed in the liquid storing box. According to the temperature joint structure capable of transmitting the earthquake force, the temperature deformation is released through the flowability of liquid in the force transmission part according to large difference between the long length of concrete temperature change time and short earthquake shock cycle, the earthquake force is transmitted according to the incompressibility of liquid, and therefore, the conflict that the temperature joint cannot transmit the earthquake force in the prior art can be solved; the temperature joint structure is reasonable in design, relatively low in cost and high in practicability.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a temperature joint structure capable of transmitting earthquake force. Background technique [0002] In the field of construction engineering, due to the influence of temperature changes in warm winter and cool summer, concrete will expand and contract, and the expansion and contraction of concrete may cause cracks in the concrete structure. The construction project is divided into several structural units. This kind of joint is called temperature joint (also called deformation joint). The temperature joint cannot transmit horizontal force, and the earthquake action is also a horizontal action. Therefore, when an earthquake occurs, each structural unit forms its own system. Resist earthquake action respectively. In the construction industry, it is generally believed that the harmful expansion and contraction caused by temperature changes is a horizontal expan...

Problems solved by technology

In the construction industry, it is generally believed that the harmful expansion and contraction caused by temperature changes is a horizontal expansion and contraction, and it is a horizontal effect, and because the earthquake action is also a horizontal action, the structure that can transmit the earthquake action must transmit the temperature effect, which is a difficult problem. contradiction

In addition, in the prior art, steel bars are generally added to reduce cracks, and induced joints are set in super-long structures to induce concrete cracking. The concrete structure has the characteristics of "the crack width increases year by year" due to temperature cracking, and the cracking of the induced joints does not occur. Conducive to the transmission of earthquake force
