Description

Technical Field

[0001] The utility model relates to the field of prefabricated component installation, in particular to a prefabricated component temporary installation device with an adjustable elevation function. Background Art

[0002] At present, the installation of prefabricated vertical exterior wall components is mainly to temporarily put the components in place by installing perforated channel steel on the side of the lower prefabricated components, and then adjust the vertical elevation of the upper prefabricated components connected to it by screws or gaskets on the top surface of the lower vertical components.

[0003] 1. Conventional perforated channel steel can only play the role of installation. Since the commonly used channel steel on the market has poor bending stiffness outside the weak axis plane, it cannot play a good role in fixing prefabricated components. When pouring concrete, it often causes horizontal deviation of the upper prefabricated components, reducing the quality.

[0004] 2. According to the design intention, the normal construction sequence is: after the prefabricated components are installed, concrete needs to be poured on the construction site to fix the relative positions of the upper and lower prefabricated components, and then the screws are loosened or the gaskets are removed to separate the upper and lower components and not directly transmit vertical forces. However, the gap between the top surface of the lower vertical component and the upper component is generally about 20 mm. Since the gap is very small and the adjustment screw is located at the center of the component, far from the edge of the component, it is almost impossible to rotate the screw through the narrow gap to achieve precise leveling of the component on site. Generally, the site is adjusted by adding gaskets later; in addition, in order to save trouble, many workers do not loosen the screws according to the design requirements after the component position is installed and concrete is poured. If gaskets are used, since the upper and lower components have been fixed, the gaskets cannot be extracted from the narrow gap, resulting in the on-site construction not being consistent with the design.
