Problems solved by technology

At present, the relevant domestic raised floor systems have not considered the relevant seismic performance in the design. The corresponding brackets and purlin systems are too thin, and the brackets and the ground are generally fixed with glue or expansion bolts, which cannot meet the preset requirements. Seismic Calculation Requirements
At the same time, when the access floor is arranged, there is a conflict between the bracket and the installation items, which makes the bracket unable to be fixed on the ground

Embodiment Construction

[0020] Such as Figure 1 to 5 As shown, an earthquake-resistant raised floor assembly includes a frame and a number of floors 5 laid on the frame. The frame includes a number of brackets and stringers 6, and two adjacent supports are connected by stringers 6 Each of the four corners of the floor 5 is provided with a first through hole 51, a bracket is placed under each first through hole 51, and the floor 5 is connected to the bracket by a detachable thread through the first through hole 51, And one edge of the two floors 5 is placed on the same stringer 6.

[0021] The bracket includes a base 1, a sleeve 2, a tray, and a support block. One end of the sleeve 2 is fixedly connected to the base 1, and a support block is installed at the other end of the sleeve 2. A locking screw 21 is provided on the pipe wall at one end.

[0022] The support block has a front end 32 with a diameter larger than the outer diameter of the sleeve 2 and a rear end 31 with a diameter smaller than the in...

Abstract

An anti-seismic movable floor assembly comprises a framework and a plurality of floor panels paved on the framework; the framework comprises a plurality of supports and stringers; two adjacent supports are connected through the stringer; four corners of the floor panel are respectively provided with a first through hole; one support is arranged below each first through hole; the floor panel is detachably screwed with the supports through the first through holes; one edges of two floor panels are arranged on the same stringer; the anti-seismic movable floor assembly can provide certain anti-seismic effect, and the supports are firmly fixed on the ground; the anti-seismic movable floor assembly cannot conflict with various items after installation.

Description

Technical field [0001] The invention relates to an anti-seismic raised floor assembly, which is a floor assembly used in the main control room of a nuclear power plant. Background technique [0002] According to the requirements of the design documents of the nuclear power plant, a 14-inch raised raised floor must be installed in the main control room of the auxiliary plant, and the raised floor system must meet the requirements of the secondary seismic performance of the nuclear power plant. At the same time, a large number of A series of installation items such as the equipment foundation, cable pipelines and duct bridge frames. At present, domestic related raised floor systems have not considered the relevant seismic performance during the design. The corresponding brackets and stringer systems are too thin. The brackets and the ground are generally fixed by glue or expansion bolts, which cannot meet the preset requirements. Seismic calculation requirements. At the same time...
