Embodiment 1

[0035] like Figure 1-7 As shown, the present invention provides a deep foundation pit safety protection device for building construction, including a support column 1, a lifting oil cylinder 2, a lifting support frame 3, a protective plate 4, and a rotating base 10 is provided on the top of the support column 1, A rotating support plate 11 is movably sleeved on the surface of the rotating base 10 , a fixed sliding rail 18 is fixed on the top of the rotating base 10 , a rotating pulley 19 is fixed at the bottom of the rotating support plate 11 , and the rotating pulley 19 rolls with the fixed sliding rail 18 Connected, the rotating pulley 19 rolls on the fixed sliding rail 18, and then the rotating support plate 11 can be flexibly rotated on the rotating base 10.

[0036] A rotating support beam 13 is fixedly arranged on the outer side of the rotating support plate 11 , a support beam rod 14 is fixedly arranged at the bottom of the rotating support beam 13 , and a buffer sleev...

Embodiment 2

[0045] A kind of deep foundation pit safety protection device for building construction according to Embodiment 1 is installed in the installation method of the foundation pit, and the method is realized by the following steps:

[0046] Step 1: Install the support column 1: erect the support column 1 at the center of the bottom of the foundation pit, and install the rotating support plate 11, the lifting cylinder 2 and the lifting support frame 3 on this basis;

[0047] Step 2: Install the side wall protection device: First, fix the fixed mounting block 26 connected with the fixing nails 27 to the bottom of the foundation pit, and then fix the extension plate 25 to the mounting block 26; finally, adjust the extension plate 25 in the storage The position of the groove 24 enables the vertical position of the foundation pit fixing vertical plate 6 to be adjusted up and down according to different depths of the foundation pit, thereby fixing the foundation pit fixing vertical plate...

Abstract

The invention relates to the technical field of building construction, and discloses a deep foundation pit safety protection device for building construction and an installation method thereof. The device includes a supporting column, and a lifting cylinder is fixed inside the supporting column. The end is fixedly provided with a lifting support frame, and the top of the lifting support frame is fixedly provided with a protective plate, and both sides of the bottom of the protective plate are provided with a foundation pit pavement, and the bottom of one end of the foundation pit pavement is fixedly provided with a foundation pit fixed vertical plate. The invention provides top protection for the construction personnel at the bottom of the foundation pit through the construction protective sloping plate, and the rotating support plate can rotate on the rotating base to realize the orientation adjustment of the construction protective sloping plate. When debris falls into the foundation pit, it will be directly hit On the surface of the construction protection sloping plate, the construction protection sloping plate is forced to rotate, the buffer sleeve is pulled by the buffer connecting rod to move on the support beam, and the force is buffered by compressing the buffer spring to improve the protection effect on the top of the construction personnel.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a deep foundation pit safety protection device for building construction. Background technique [0002] The foundation pit is a soil pit excavated at the base design position according to the base elevation and the size of the base plane. Before excavation, the excavation plan should be decided according to the geological and hydrological data and the conditions of the buildings near the site, and waterproof and drainage work should be done. If the excavation is not deep, the method of placing the slope can be used to stabilize the soil slope, and the size of the slope is determined according to the relevant construction regulations; [0003] In order to ensure construction safety, it is usually necessary to fix the support structure in the building foundation pit to support the inner wall of the foundation pit. Most of the existing foundation pit support structure...
