Embodiment 1

[0022] Such as figure 1 Shown, a kind of outdoor construction elevator foundation reinforcing device comprises building exterior wall 6, indoor reinforced concrete floor slab 8, original soil layer 4, I-beam 1 and construction elevator foundation 5, and described building exterior wall 6 and described original soil There is backfill soil 10 between the layers 4, and the building exterior wall 6 is provided with installation holes 9, and a concrete cushion 3 is poured on the original soil layer 4, and the concrete cushion 3 can improve the stress strength of the construction elevator foundation 5, Two round bars 2 are pre-embedded on the concrete cushion 3, and the root of the installation hole 9, the upper surface of the indoor reinforced concrete floor 8 and the upper surface of the concrete cushion 3 are all located on the same horizontal plane, so that Make the force-bearing surface of the bearing construction elevator foundation 5 uniformly stressed. One end of the I-beam...

Embodiment 2

[0025] The difference from Example 1 is that a round steel 2 is pre-embedded on the concrete cushion 3 .

Embodiment 3

[0027] The difference from Example 1 is that one end of the I-beam 1 is fixedly installed on the indoor reinforced concrete floor 8 through a fixed iron block 7, and the side of the fixed iron block 7 is fixed on the outer wall 6 of the building. On the inner surface, this setting can strengthen the fixed installation of one end of the I-beam 1, so that the elevator is not easy to move during construction and avoids danger.

Abstract

The invention discloses an outdoor construction elevator foundation reinforcing apparatus, comprising a building exterior wall, an indoor reinforced concrete floor, a primitive soil layer, an I-beam and a construction elevator foundation; backfill soil is arranged between the building exterior wall and the primitive soil layer, the building exterior wall is provided with a mounting hole, a concrete cushion is cast above the primitive soil layer, a plurality of round bars are embedded in the concrete cushion, all the bottom of the mounting hole, the upper surface of the indoor reinforced concrete floor and the upper surface of the concrete cushion are positioned on a same horizon, one end of the I-beam is passed through the mounting hole and is fixedly mounted on the indoor reinforced concrete floor, the other end of the I-beam is fixedly mounted on the concrete cushion through the round bars, and the construction elevator foundation is arranged on the I-beam. The construction elevator foundation is supported with the I-beam; the outdoor construction elevator foundation reinforcing apparatus simple to operate and convenient to construct, non-uniform settlement of the construction elevator foundation can be avoided effectively, and safety is good.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to an outdoor construction elevator foundation reinforcement device. Background technique [0002] As a vertical transportation tool, construction elevators are widely used in construction projects. For deep foundation pit engineering, when the building is equipped with a construction elevator, it often occurs that the construction elevator is located on the backfill soil between the building and the outside of the foundation pit. Insufficient ground will lead to uneven settlement of the construction elevator foundation. With the prolongation of construction time, the deformation of the backfill soil will increase, which may lead to uneven stress on the steel pipe scaffolding support system, and some of them may not even function as a support, thus affecting the normal use of the construction elevator. , and even serious security problems.
