In the embodiment shown in fig. 7, 8 and 9, the support 43 and the diagonal brace connection plate 44 are not mounted on the second column connection member 42, but it should be apparent to those skilled in the art that the structure in which the ground beam 5 and the rib plate 52 are connected to the casing 4 through the diagonal brace connection plate 44 and the support 43 is predicted.
Wherein, the ground beam 5 adopts H-shaped steel, and the web and the pterygoid lamina of the ground beam 5 are connected to the floor 52.
The construction process of the temporary support system comprises the following steps:
step one, drilling holes on the structural column 1 to install a first anchor bolt 11, and fixing a first column connecting piece 41 and a second column connecting piece 42 through the first anchor bolt 11 and a first nut 12;

In the above temporary support system, since the casing 4 needs to be sleeved on the outer side of the structural column 1, the casing 4 must be welded or spliced on site for this purpose, and the structural columns 1 of different buildings have different sizes, which makes it difficult to recycle the casing 4, and the cost of discarding the casing 4 is too high.
To solve the above technical problems, the following provides an embodiment of a structural column casing for a temporary support system for foundation reinforcement, please refer to fig. 10, 11, 12, 13:
the first column connector 41 or the second column connector 42 includes: anchor bolt connection plates 45 and corner plates 46;
the anchor bolt connecting plate 45 is in a flat plate shape, the anchor bolt connecting plate 45 is attached to the surface of the structural column 1, a gap is formed between two vertical edges of the anchor bolt connecting plate 45 and corners of the structural column 1, and through holes 451 which are in one-to-one correspondence with each first anchor bolt 11 are formed in the anchor bolt connecting plate 45;
the corner protection plate 46 is angle steel, the corner protection plate 46 is attached to two sides of the corner of the structural column 1, two vertical edges of the corner protection plate 46 are covered on the outer wall of the anchor bolt connecting plate 45, long holes 461 corresponding to the through holes 451 one by one are formed in the corner protection plate 46, and the first anchor bolts 11 penetrate through the through holes 451 and the long holes 461 to be connected with the first nuts 12 so as to fixedly connect the anchor bolt connecting plate 45 and the corner protection plate 46.
The corner protector 46 has different thicknesses at different locations so that the corner protector 46 is in the side adjacent to the structural post 1: a part of the corner protection plates 46 are attached to the wall surface of the structural column 1; while another portion of the gusset 46 engages the outer wall of the anchor web 45 and covers the gap between the anchor web 45 and the corner of the structural column 1. As the size of the structural column 1 changes, the width of the void changes, as does the area of overlap between the corner plates 46 and the anchor web 45, thereby allowing the casing 4 formed by the anchor web 45 and the corner plates 46 to accommodate structural columns 1 in a range of sizes.
Referring to fig. 14 and 15, when the first and/or second post connecting members 41 and 42 are/is connected with the support member 43, the support member 43 is connected with the anchor bolt connecting plate 45, and the corner protector 46 is provided with a first notch 462 for avoiding the support member 43.
Further, when the structural column 1 is deflected, the force applied to the anchor bolt connecting plate 45 to which the supporting member 43 is connected is perpendicular to itself, and the force applied to the anchor bolt connecting plate 45 to which the supporting member 43 is not connected is parallel to itself, if the long hole 461 is horizontally arranged, the corner protector 46 is connected to the first anchor bolt 11 only by the friction of the first nut 12 when the corner protector 46 moves along the length direction of the long hole 461, and in order to solve this problem, please refer to fig. 12:
the length direction of the long hole 461 is inclined to the horizontal plane.
When the corner protector 46 moves in the horizontal direction, the tensile force applied to the first anchor 11 by the corner protector 46 is applied to the first anchor 11 through the inclined inner wall of the long hole 461.
Further, since the corner protection plate 46 is connected to the first anchor bolt 11 through the slot 461, the corner protection plate 46 will slightly displace when being stressed, and further the internal corner of the corner protection plate 46 will press the corner of the structural column 1 when displacing, resulting in the corner breakage of the structural column 1, in order to solve this problem, please refer to fig. 13 and 15:
the inside corner of the corner protector 46 is provided with an inwardly concave second notch 463, the second notch 463 being adapted to avoid the corner of the structural pillar 1.
When the corner protector 46 is slightly displaced, the corner of the structural post 1 moves relative to the corner protector 46 inside the second notch 463, so that the corner protector 46 avoids pressing the corner of the structural post 1.
