The fixed furred ceiling that does not need each specialty to punch alone to and the vexation of cross operation. When the clean room ceiling is constructed, after the C-shaped steel is pre-embedded for one time, the MEP electromechanical pipeline support is hung on the clean room ceiling and is shared with the ceiling. The method reduces the complexity of working procedures in the aspect of construction, can not be well connected in order, and simultaneously reduces the work of cleaning for a plurality of times due to multiple pollution.

Description

Method for installing upper fixed node of clean ceiling of electronic factory building

Technical Field

The invention belongs to the field of ceiling installation, and particularly relates to an installation method of an upper fixed node of a clean ceiling of an electronic factory building.

Background

The ceiling of the clean room is connected with the structural floor slab, and the expansion anchor bolt single-point fixing is adopted in the conventional method.

At present, chinese patent with publication number CN105507478A discloses a furred ceiling installation component, including lead screw, main joist, connection hanger, triangle fossil fragments, the lead screw passes through expansion bolts to be fixed to the building top surface, it uses the nut to pass through to connect hanger the screw with lead screw swing joint, the main joist cup joints in the connection hanger, still includes bilateral hanging piece, bilateral hanging piece carries on the main joist, the part of the suspension clasp at bilateral hanging piece both ends is do not the straining triangle fossil fragments reach the atress and spread out smoothly, the direction of triangle fossil fragments with the direction of main joist is perpendicular.

The prior art comprises the following contents: typesetting according to the size of the ceiling board of the clean room, firstly carrying out construction setting in the X-axis direction and the Y-axis direction, mechanically punching and installing an expansion anchor bolt lower hanging suspender at a cross point, and then installing a hanging part and a keel.

The existing installation process has the following defects: if the construction paying-off and punching positions are inaccurate, construction deviation exists, and accumulated deviation exists, the installation cannot be carried out, secondary punching and hole patching are carried out, and the installation is relocated; even small deviations can affect the verticality of the lower suspension system.

Disclosure of Invention

The invention aims to provide a method for installing a fixed node at the upper part of a clean ceiling of an electronic factory building. The device has the advantages of convenient, quick, flexible and bidirectional adjustment in field installation, one-time pre-embedding and multiple sharing.

The purpose of the invention can be realized by the following technical scheme:

a method for installing a fixed node at the upper part of a clean ceiling of an electronic factory building comprises the following installation steps:

s01, paying off at the bottom of the structural floor slab, and installing C-shaped steel by using anchor bolts;

s02, mounting a screw rod of the suspended ceiling through a spring nut at the lower notch of the C-shaped steel;

s03, adjusting the position of the suspender in the X direction of the lower notch of the C-shaped steel according to the arrangement of the ceiling tiles;

s04, installing a connecting piece at the lower part of the suspender, and fixing the connecting piece with the ceiling keel to realize Y-direction adjustment;

s05, mounting an MEP electromechanical pipeline support in the suspended ceiling, and fixing the suspended ceiling with the C-shaped steel through a spring nut;

and S06, checking and accepting, finally installing the ceiling board, adjusting the levelness and the verticality, and finishing the installation.

Adopt rearmounted pre-buried C shaped steel mode, fix C shaped steel in the structure bottom with the crab-bolt earlier, then hang substructure through C shaped steel notch, satisfy toilet's suspension system problem promptly, also solved MEP electromechanical pipeline support hanging point problem simultaneously. The fixed furred ceiling that does not need each specialty to punch alone to and the vexation of cross operation.

When the clean room ceiling is constructed, after the C-shaped steel is pre-embedded for one time, the MEP electromechanical pipeline support is hung on the clean room ceiling and is shared with the ceiling. The method reduces the complexity of working procedures in the aspect of construction, can not be well connected in order, and simultaneously reduces the work of cleaning for a plurality of times due to multiple pollution.

The invention has the beneficial effects that:

(1) the traditional single-point fixing method is changed by adopting a post-embedded C-shaped steel mode;

(2) the ceiling of the clean room is convenient to install, and meanwhile, the ceiling problem of the MEP electromechanical pipeline support can be solved;

(3) in the aspect of construction process, the construction method is used for multiple times through one-time pre-embedding;

(4) avoid punching and pre-burying for many times, dust pollution for many times brings the vexation for cleaning work.

Detailed Description

Example 1: a method for installing a fixed node at the upper part of a clean ceiling 5 of an electronic factory building, as shown in figures 1 and 2, comprises the following installation steps:

s01, constructing and paying off at the bottom of the structural floor slab, and installing C-shaped steel 2 by using anchor bolts 1;

s02, mounting a screw rod of the suspended ceiling 5 on the lower notch of the C-shaped steel 2 through a spring nut 3;

s03, adjusting the position of the suspender 6 in the X direction of the lower notch of the C-shaped steel 2 according to the arrangement of the ceiling 5 plates;

s04, installing a connecting piece 7 at the lower part of the suspender 6, and fixing the connecting piece 7 with a keel of the suspended ceiling 5 to realize Y-direction adjustment;

s05, mounting an MEP electromechanical pipeline support 9 in the suspended ceiling 5, and fixing the suspended ceiling 5 and the C-shaped steel 2 through the spring nut 3;

and S06, checking and accepting, finally installing the suspended ceiling 5 plate, adjusting the levelness and the verticality, and finishing the installation.

Adopt rearmounted pre-buried C shaped steel 2 mode, fix C shaped steel 2 in the structure bottom with crab-bolt 1 earlier, then hang substructure through C shaped steel 2 notches, satisfy toilet's suspension system problem promptly, also solved MEP electromechanical pipeline support 9 simultaneously and hung a little problem. The fixed suspended ceiling 5 does not need to be punched independently by each specialty to and the trouble of cross operation is avoided.

When the clean room suspended ceiling 5 is constructed, after the C-shaped steel 2 is pre-embedded for one time, the MEP electromechanical pipeline support 9 is hung on the top and is shared with the suspended ceiling 5. The method reduces the complexity of working procedures in the aspect of construction, can not be well connected in order, and simultaneously reduces the work of cleaning for a plurality of times due to multiple pollution.

(1) The traditional single-point fixing method is changed by adopting a mode of rear pre-embedding C-shaped steel 2;

(2) the clean room ceiling 5 is convenient to install, and meanwhile, the problem of the MEP electromechanical pipeline support 9 ceiling 5 can be solved;

Finally, it should be noted that: although the present invention has been described in detail with reference to the above embodiments, it should be understood by those skilled in the art that: modifications and equivalents may be made thereto without departing from the spirit and scope of the invention, and the appended claims are intended to cover such modifications and equivalents as fall within the true spirit and scope of the invention.
