Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
As shown in fig. 1 to 4, the inner support span reducing device for foundation pit of the present invention is adapted to, at the time of operation, fully weld and reinforce the steel connecting beam 6 with the steel plate 1 having a thickness of h ═ 10mm, so that the steel connecting beam 6 is integrated to increase the overall stability of the steel connecting beam 6,
The round steel 3 passes through
The length of the steel tube 4 is,
the round steel 3 is fully welded on the steel connecting beam 6 at two sides, and then two round steel 3 are used
The first steel cables 5 are respectively hooped on
Round steel 3 and
the first roller consisting of the steel pipe 4 is wound around the second roller on the upper part of the steel connecting beam 6 and then buckled on two S-shaped hooks
L is 240 and 00 type basket screw 1.3 spiral buckle, and another end of the basket spiral buckle is connected with a second steel cable and finally connected to the lattice column, thus two groups of basket spiral buckles can be adjusted to force two groups of first steel cables 5, and the steel connecting beam 6 generates upward force under the effect of two groups of first steel cables 5, so that the steel connecting beam 6 which influences the erection of the formwork support can still bear the weight of steel support, two groups of first steel cables 5 need to keep a certain distance and bear force simultaneously, when the span reducing device works, the steel connecting beam 6 which influences the height of the scaffold can be cut, and then the scaffold can be conveniently erected, thereby facilitating the next construction process.
