Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] During the specific implementation: a method for controlling the expansion and deformation of the ground of the factory building for vehicles and protecting the load. In this method, expansion joints are set in the ground structure of the workshop for vehicles to control the expansion and deformation of the ground, and at the same time, expansion joints are set in the expansion joints for force transmission The load-bearing protection of the ground is carried out by the structure, which is characterized in that the force transmission structure of the expansion joint adopts a horizontally arranged plate-shaped member so that its two ends are connected to the two side walls of the expansion joint, and at least one end of the plate-shaped member is formed so that the horizontal direction is different. Constrained free end.

[0034]In this way, when the gr...

Abstract

The invention discloses a ground expansion deformation control and force-bearing protection method for a plant for vehicle passing. According to the method, expansion joints are arranged in a ground structure of the plant for vehicle passing to conduct ground expansion deformation control, and meanwhile, expansion joint force transmission structures are arranged in the expansion joints to conduct ground force-bearing protection. The method is characterized in that horizontally-arranged plate-like members are adopted in the expansion joint force transmission structures to enable the two ends of each expansion joint force transmission structure to be connected to the two side walls of the corresponding expansion joint, and at least one end of the expansion joint force transmission structure is a free end which is not restrained in the horizontal direction. By means of the method, while the function of the ground expansion joints is not affected, the force bearing and transmitting effects of the ground on the two sides of the expansion joints can be improved, and the ground protection effect is improved.

Description

technical field [0001] The invention relates to the technical field of building ground structure protection; in particular, it relates to a method for controlling the expansion and contraction deformation of the ground of a vehicle workshop and protecting the load. Background technique [0002] Modern industrial plants have higher and higher requirements for the flatness and crack resistance of large-area ground, especially for large-area load-bearing industrial plant floors, because they often need to be open to traffic and load-bearing, concrete floors made of concrete and cement are generally used. However, the floor of the factory building is generally wider and larger, and the cement floor usually cracks due to its own expansion and deformation after the cement floor area is large. [0003] But the existence of expansion joints destroys the integrity of the pavement. In order to ensure the load-transmitting capacity of the joints, the load-bearing concrete floor is equ...
