Technical Points of Colored Steel Plate Installation on Walls in Animal Laboratories
创建于04.09
In the construction of animal laboratories, the selection and installation of wall materials are of great significance. Colored steel plates, with their numerous advantages such as good heat insulation, fire resistance, moisture resistance, as well as being aesthetically pleasing and easy to clean, have become an ideal material for the walls of animal laboratories. As Guangzhou Cleanroom Construction Co., Ltd., which specializes in the production of purification equipment, we deeply understand the importance of colored steel plate installation technology in creating a high - quality animal laboratory environment. Today, we will introduce in detail the technical points of colored steel plate installation on walls in animal laboratories.
I. Preparation Work before Installation
(1) Material and Tool Preparation
Selection of Colored Steel Plates
According to the specific needs of the animal laboratory, select colored steel plates of appropriate specifications and quality. Generally, attention should be paid to the thickness of the colored steel plate, the quality of the coating, the type of core material, etc. For example, for areas with high requirements for environmental cleanliness, colored steel plates with rock wool as the core material can be selected. Rock wool has good fire - resistance, heat - preservation, and sound - insulation properties, and is not easy to breed bacteria. At the same time, ensure that the surface of the colored steel plate is flat, without scratches, deformation, or other defects.
Preparation of Auxiliary Materials
Prepare all kinds of auxiliary materials required for installation, such as sealants, self - tapping screws, angle irons, channel steels, etc. The sealant should have good weather resistance, water resistance, and sealing performance to ensure the sealing effect of the wall; the self - tapping screws should be selected in appropriate specifications according to the thickness of the colored steel plate to ensure firm fixation.
Tool Equipping
The installation tools include electric drills, screwdrivers, cutting machines, spirit levels, straightedges, etc. Ensure that the tools are in good condition and their accuracy meets the requirements. For example, spirit levels and straightedges are used to ensure the verticality and horizontality of wall installation.
(2) On - site Investigation and Planning
Measuring and Marking
Before installation, accurately measure and mark the installation position of the walls in the animal laboratory. Determine the axis position of the walls according to the design drawings, and draw ink lines on the ground and ceiling. Pay attention to error control during the measurement process to ensure that the positions of each wall are accurate, providing a benchmark for subsequent installation.
Wall Base Treatment
Check the condition of the wall base to ensure that the base is flat, firm, and dry. If there are uneven or loose phenomena in the base, leveling and reinforcement treatments are required. For example, for a concrete wall, if there are unevenness, it should be leveled with cement mortar; for an old wall, clean the dust, oil stains, and other impurities on the surface to ensure good adhesion between the colored steel plate and the base.
II. Technical Points during the Installation Process of Colored Steel Plates
(1) Installation of Keels
Selection and Processing of Keels
According to the size of the colored steel plate and the wall structure, select appropriate keel materials. Generally, light - steel keels are used. Process the keels, cut them into corresponding lengths according to the measured and marked positions, and carry out rust - removal and anti - corrosion treatments.
Installation and Fixation of Keels
First, install the vertical keels, fix them to the embedded parts or expansion bolts on the ground and ceiling to ensure that the keels are vertical. The spacing of vertical keels should be reasonably set according to the width of the colored steel plate, generally not exceeding 600mm. Then install the horizontal keels, and fix them to the vertical keels through connectors to form a stable keel framework. During the installation process, use a spirit level and a straightedge to check the verticality and horizontality of the keels at any time, and control the deviation within the allowable range.
(2) Installation of Colored Steel Plates
Cutting of Colored Steel Plates
Cut the colored steel plates accurately according to the size of the keel framework. Use a professional cutting machine when cutting to ensure that the cut is neat, smooth, and the size is accurate. Note to leave a certain installation margin to ensure that the colored steel plates are tightly spliced after installation.
Installation Sequence of Colored Steel Plates
Start from one end of the wall and install the colored steel plates one by one. Insert the colored steel plates into the keel framework, making the tongues of the colored steel plates interlock with the tongues of adjacent colored steel plates. Use self - tapping screws to fix the colored steel plates to the keels. The screw spacing is generally 200 - 300mm, evenly distributed around the colored steel plate. During the installation process, check the flatness and verticality of the colored steel plates at any time, and adjust them in time if there are deviations.
Treatment of Yin and Yang Corners
At the yin and yang corners of the wall, special yin and yang corner lines are required for treatment. Fix the yin and yang corner lines to the colored steel plates and keels to ensure that the yin and yang corner lines are straight, beautiful, and enhance the overall stability and sealing performance of the wall.
(3) Sealing Treatment
Sealing of Plate Joints
After the installation of colored steel plates is completed, seal the plate joints. First, use a sealant gun to evenly inject the sealant into the plate joints, fill them fully, and then use a scraper to scrape the sealant flat to make it flush with the surface of the colored steel plate. The sealant should be applied evenly, without missing coating, air bubbles, or other phenomena to ensure the sealing performance of the wall and prevent the entry of dust, microorganisms, etc.
Sealing of Penetrating Holes
For various penetrating holes on the wall, such as holes through which electrical conduits, water pipes, etc. pass, materials with good fire - resistance, water - resistance, and sealing performance should be used for blocking. First, fill the holes with fire - resistant putty, and then apply sealant on the surface to ensure that the holes are tightly sealed and do not affect the environmental control effect of the laboratory.
III. Inspection and Acceptance after Installation
(1) Appearance Inspection
Overall Flatness
Observe whether the colored steel plate wall is overall flat, without obvious unevenness. Use a straightedge to check the flatness of the wall, and the deviation should meet the relevant standard requirements, generally not exceeding 2mm.
Quality of Plate Joints
Check whether the plate joints of the colored steel plates are uniform and straight, whether the sealant is applied smoothly and without cracking or falling off. The width of the plate joints should be controlled within the design requirements, generally 3 - 5mm.
Effect of Yin and Yang Corners
Check whether the yin and yang corner lines are firmly installed, whether the lines are straight, and whether the angles of the yin and yang corners meet the requirements, generally 90°.
(2) Performance Testing
Sealing Performance Testing
Use methods such as smoke testing or pressure testing to test the sealing performance of the wall. Create a certain concentration of smoke inside the laboratory and observe whether there is smoke leakage outside the wall; or pressurize the inside of the laboratory and detect the pressure drop rate to determine whether the sealing effect of the wall meets the requirements.
Strength Testing
Check whether there are hollow sounds by tapping the colored steel plate wall to determine whether the connection between the colored steel plate and the keel is firm. If necessary, professional testing instruments can be used to test the strength of the wall to ensure that the wall can withstand a certain external force and meet the use requirements of the animal laboratory.
