Problems solved by technology
[0003] The current foundation pit maintenance boards are generally inserted vertically into the foundation pit through various insertion structures, but there are many deficiencies in the use of this structure of maintenance boards. The biggest disadvantage is that when working on the edge of the foundation pit, the external force makes the foundation pit Squeeze the maintenance plate, and then separate the maintenance plate from the inner wall of the foundation pit. Once the maintenance plate is separated, the entire foundation pit is very easy to collapse, causing accidents
The way of fixing perpendicular to the inner wall of the foundation pit is easy to loosen once a pressure is applied from the side. This is the most common problem in the use of maintenance panels at present. If it is fixed by concrete pouring, it will be very troublesome to disassemble later

Embodiment Construction
[0020] Such as figure 1 and figure 2 As shown, the foundation pit maintenance board of this building includes more than one maintenance board device installed in the foundation pit 4. The maintenance board device includes fixed stop rods 5 fixedly inserted and installed in the upper and lower ends of the foundation pit 4, and the fixed stop rods 5 are installed More than one maintenance plate 1, one side of the maintenance plate 1 on the fixed stop bar 5 is provided with more than one reinforcement mechanism 6, the upper and lower ends of the maintenance plate 1 are respectively in contact with the reinforcement mechanisms 6 on the fixed stop bar 5, through the upper and lower ends The reinforcement mechanism 6 deforms the maintenance plate 1 into an arched shape, and the deformed arched surface of the maintenance plate 1 is arranged close to the wall of the foundation pit.
[0021] Among them, such as image 3 As shown, the reinforcement mechanism 6 includes a fixed cavity...

The invention discloses maintenance boards for a building foundation pit. The maintenance boards comprise more than one maintenance board device installed in the foundation pit, wherein the maintenance board devices comprise fixed stop levels fixedly inserted and installed at the upper and lower ends of the foundation pit, more than one maintenance board is installed between the fixed stop levels,more than one reinforcement mechanism is respectively provided on the side of the fixed stop levels opposite to the maintenance boards, the upper and lower ends of the maintenance boards respectivelycontact the reinforcement mechanisms on the fixed stop levels, the upper and lower end reinforcement mechanisms make the maintenance boards deformed into an arch shape, and the arched surfaces of themaintenance boards after deformation are set close to the foundation pit wall. The maintenance boards of the invention change the traditional installation method such that the maintenance boards canact the force applied by the foundation pit on the fixed stop levels at the upper and lower ends, and has a secondary reinforcement function to greatly improve the protection strength of the maintenance boards and prevent the maintenance boards from loosing and falling off.
Description
technical field [0001] The invention relates to the construction field, in particular to a building foundation pit maintenance board. Background technique [0002] Housing construction projects refer to various types of housing construction and its ancillary facilities, as well as supporting lines, pipelines, equipment installation projects and indoor and outdoor decoration projects. , to meet the needs of people's production, living, learning, public activities, etc. During the construction of building foundation pits, in order to ensure construction safety and prevent landslide accidents, support measures must be taken for the excavated building foundation pits. The protection design and construction should comprehensively consider the engineering geological and hydrogeological conditions, foundation pit type, foundation pit excavation depth, drainage conditions, the requirements of the surrounding environment for the displacement of the foundation pit side wall, the surro...
