First, preparation before installation
Before the entrance of the entrance, the floor plans, doors and windows, and large-scale drawings must be integrated, and then the site openings and actual quantities should be compared to ensure that the windows and doors, large-scale drawings, specifications, models, and quantities are consistent. In order to grasp the installation of each part and the corresponding baseline data, Party A needs to make a technical explanation in written form. To avoid unnecessary disputes during the installation process. Pay attention to the following points when submitting the bottom: A. Install according to the building's 1000NM line. B. Data reserved for the intersection of the frame and the wall (especially tiling and hanging marble); wall displacement or corresponding changes, data, etc.
Installation of door frames
The steel fire door frame that has arrived at the site is sorted and transported to the corresponding floor according to the specifications, model and quantity. The frame is filled with cement mortar, and then the door frame is transported to the installation position. Then check whether the level line and opening direction of the opening match. Fire-resistant door with buckle edge and electrical equipment is installed by the wall; other walls are installed. After the conditions are met, the door frame is erected at the opening of the hole and fixed with a special wooden plug to make the door frame horizontally at an appropriate position (suitable for the level of the level), and measure the diagonal, flatness, verticality, and elevation line, and then use the sides of the door frame. 10mm * 100mm expansion bolts or tension bars are fixed on the wall, and finally check whether the installation standard of the door frame meets the requirements of the code.
Installation of door leaf
According to the actual situation of the construction site, propose an appropriate delivery date. When the product is delivered to the construction site, find an appropriate place to place it. During installation, it is transported in place according to the model classification, and the fan is connected to the frame with a hinge. Adjust the door seam evenly according to the technical requirements. If it rebounds, it should be corrected in time. If the size and keyhole are found to be inaccurate, it can be processed in time. If it cannot be put back into the finished product storage area, report to the supervisor for treatment measures. Remember: Double-doors should be adjusted after the door seam is adjusted. If there is deformation, do not knock. Use the corresponding tools to operate it, otherwise you will lose sight, and the door will not close tightly and loose when the door is opened.
Installation of door accessories
Before operation, you must understand the performance of the accessories, and then check whether the door frame and door leaf are qualified for commissioning, and then configure the corresponding number of accessories according to the contract before installation, but you must pay attention to the following points:
a) Each panel and screw of the door lock should be flat or rusty screws should be replaced.
b) The misaligned keyholes and screw holes must be handled in time, and can not be forced to install: it can not be replaced with other screws or nails: when the power tool must be handled with a power tool, it should be reported to the supervisor in time.
c) The number of the door lock must be compiled according to the requirements of the owner.
d) After completion, check the opening of the door lock, and check whether the screws and holes are missing.
e) Do not hit the door frame with a hammer during operation, otherwise the door frame will be deformed and empty.
f) Packaging paper bags must not be littered. Use them to bundle locks, do a good job of protection, prevent pollution and rust, and clear the field after completion.
g) Double-open fire doors of evacuation aisles shall be installed with door closers, sequencers, and aisle locks. Single-open, large and small fans shall be installed with double-opened door closers and aisle locks. Double-open fire doors in the equipment room should be installed with door closers, sequencers, and fire locks, and double-opened doors with large and small fans should be installed with door closers and fire locks. Install tube well locks on all tube wells. Finally, it is necessary to perform function debugging.
Five, clean up
The completion date and progress of the project are well mastered. The debris on the door frame should be cleaned at an appropriate time. The method is: press the edge of the door with a hanging ruler, draw a straight line with a blade, and then clean up. If the mortar on the door frame is too much and too thick, you should pay attention to cleaning methods, and gently tap to keep the edge of the door frame horizontal and vertical. Because all the door paint on the construction site has been prepared, it must be repaired in case of collision injuries. Door leaf is cleaned in the same way). Keep in mind that you must clean up the site after all the procedures are completed, develop habits and achieve civilized construction. Good construction habits can leave a deep impression on Party A.
