Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
The first embodiment is as follows: as shown in fig. 1-2, a temporary support loose joint assembly for partial disassembly of building components comprises two i-beams 1, four pairs of upper rectangular steel plates 2 and four pairs of lower rectangular steel plates 3, wherein the upper rectangular steel plates 2 and the lower rectangular steel plates 3 are used in pairs, bolt holes are respectively and correspondingly arranged at two ends of the upper rectangular steel plates 2 and the lower rectangular steel plates 3, the distance between the bolt holes arranged on the upper rectangular steel plates 2 is greater than the width of the i-beams 1, the distance between the bolt holes arranged on the lower rectangular steel plates 3 is greater than the width of the i-beams 1, each pair of the upper rectangular steel plates 2 and the lower rectangular steel plates 3 is respectively provided with two long screws 4, external threads are arranged at two ends of each long screw 4, each long screw 4 is provided with a high-strength hexagon nut, a gasket can also be used, and the length of each long screw 4 is greater than the thickness of the upper rectangular steel plates 2, the sum of the thickness of the I-shaped steel 1, the thickness of the structural plate 5 to be punched and the thickness of the lower rectangular steel plate 3. The upper rectangular steel plate 2 is provided with a hanging ring 6.
When the structural slab 5 is a concrete slab, the dismantling construction mode is as follows:
