Description

Technical Field

[0001] The invention relates to the technical field of fire door frame grouting, in particular to an L-shaped template tool for fire door grouting. Background Art

[0002] The current fireproof door frame grouting process is to use foam glue to seal the joints between the door frame and the wall before grouting, and then perform grouting after sealing. After the grouting liquid has finally set, the foam glue is removed and mortar is used for secondary sealing.

[0003] However, the existing grouting construction method of fire doors has the following disadvantages: this process has certain defects. On the one hand, it increases the cost of secondary construction. On the other hand, it is subject to management constraints and is prone to the process of directly applying fireproof glue or putty without deducting the foam glue, which can easily cause fire hazards that the fire protection level does not meet the requirements. In addition, during the grouting process, the door frame is affected by the grouting and its stability becomes poor and it is easy to move. Therefore, a device is needed to solve the above problems. The present invention sets up an aluminum mold, and the aluminum mold is erected parallel and perpendicular to the intersection of the wall to form an L shape, a grouting strip is used at the intersection of the aluminum mold and the wall, and a positioning screw is used. The aluminum mold sets up the fire door frame After completion, the L-shaped aluminum formwork is made perpendicular to the wall, and positioning screws and positioning nuts are used for positioning according to the width of the fire door frame. The screws are tightened, and after positioning with the positioning screws and positioning nuts, the L-shaped aluminum formwork is reinforced. After completing the above construction process, grouting holes are reserved for the fire door frame for grouting. After the grouting is finally set, the formwork is removed. According to the L-shaped formwork tool for grouting of fire doors in this embodiment, when in use, the L-shaped formwork tool is used to grout the fire door frame. The construction is simple, the one-time molding effect is good, and no secondary repair or sealing is required. It meets the fire protection acceptance requirements of the fire door and saves labor costs and construction period. Summary of the Invention
