Problems solved by technology

[0004] However, there are still major defects in the existing technology, such as: prefabricated concrete walls are prone to thermal expansion and contraction under the external environment, which makes the joints of the two prefabricated concrete walls squeeze each other or move away from each other, resulting in two prefabricated concrete walls The problem that the wall connection is easy to break and damage

Embodiment 1

[0040] A connection structure for prefabricated concrete walls, comprising a wall 1, one end of the wall 1 is fixedly connected with several plugs 2, and the other end of the wall 1 is provided with plugs for inserting the plugs 2 of adjacent walls 1 one by one. Slot 101, insert the insert block 2 into the slot 101 of the adjacent wall body 1 to realize the connection between the adjacent wall bodies 1, and improve the connection between the adjacent wall bodies 1 through the matching connection of multiple slots 101 and the insert block 2 Strength, the end of the plug 2 away from the wall 1 is provided with a chute 201, and the slot 101 is fixed with an elastic bag 3 for storing evaporating liquid. The evaporating liquid can be water, and the plug 2 is inserted into the slot 101 and squeezed In the elastic bag 3, the evaporating liquid is heated and evaporated to form a gas, and the evaporated gas is liquefied again to form a liquid. The evaporating liquid enters the runner g...

Embodiment 2

[0051] Embodiment 2 On the basis of Embodiment 1, the connection of the wall body 1 is optimized, that is: there is a gap between adjacent wall bodies 1, and the gap is fixed and adhered by the elastic layer 20, and the elastic layer 20 is preferably made of asphalt. , by leaving a gap between adjacent walls 1, reduce the damage of thermal expansion to the junction of adjacent walls 1, and further reduce the damage of thermal expansion to the junction of adjacent walls 1 by applying elastic layer 20, and apply the elastic layer 20 also plays windproof, attractive in appearance effect.

Embodiment 3

[0053] Embodiment 3 On the basis of Embodiment 1, an elastic water-proof ring 21 is added, that is, an elastic water-proof ring 21 is fixedly connected to the inner wall of the elastic bag 3 close to the resistance groove 103, and the first resistance rod 12 slides through the elastic water-proof ring. The setting of the ring 21 and the elastic water-proof ring 21 prevent the evaporating liquid from flowing out through the connection between the first resistance rod 12 and the elastic bag 3, which will bring harm to the overall device.

Abstract

The invention discloses a connection structure of a prefabricated concrete wall and a construction method thereof. One end of the wall is fixedly connected with an insertion block, and the other end of the wall is provided with a slot, and the end of the insertion block far away from the wall is provided with a chute, and the end faces of the extrusion block and the chute that are close to each other are fixedly connected with extrusion-fit elastic bumps, and an elastic bag for storing evaporative liquid is fixedly arranged in the slot, and the heating and cooling circuit includes a first semiconductor plate, the second semiconductor board, the first power supply, the second power supply and a bidirectional switch, the bidirectional switch includes a sliding connecting rod, a first resistance rod, an insulating connecting rod and a second resistance rod, and in use of the present invention, through evaporation The evaporation and expansion of the liquid absorbs the external heat, reducing the thermal expansion hazard of the wall connection, and through the setting of the heating and cooling circuit, the first semiconductor board can perform self-adjustable thermal compensation on the wall connection, further reducing the heat loss caused by the wall connection. Damage due to thermal expansion and contraction.

Description

technical field [0001] The invention relates to the technical field of concrete connection structures, in particular to a connection structure of prefabricated concrete walls and a construction method thereof. Background technique [0002] Prefabricated concrete structure is suitable for industrialization and is the development direction of housing industrialization. The joint connection structure between prefabricated components in precast concrete structures determines the overall performance of the structure. The existing prefabricated concrete structure nodes are generally the weak link of the assembled integral concrete structure, which affects the mechanical performance, and the structure is relatively complicated, and it is easy to crack and affect the performance during the use stage. [0003] In the prior art, a connection structure of precast concrete walls with the application number "201210329579.7" includes a first precast concrete wall and a second precast con...
