Description

Technical Field

[0001] The utility model relates to the field of building construction safety protection facilities, in particular to a standardized hole protection device. Background Art

[0002] With the rapid development of science and technology and economy, high-rise buildings are springing up in large numbers. Elevators have become an indispensable means of transportation for high-rise buildings. Each elevator will generate n elevator door openings. If the number of elevators is multiplied by the number of floors of each high-rise building, the number of elevator door openings generated will be an astonishing number. For this reason, the protection of elevator door openings is particularly important. It is also common to fall from elevator door openings during construction. The main reasons are: the elevator shaft door opening is not protected, the elevator shaft door opening protection is removed, and the elevator shaft protection door is unqualified. Therefore, the protection of elevator shaft door openings is particularly important for construction safety. However, how to protect them in a timely and effective manner is of great significance to avoiding safety accidents. Utility Model Content

After the assembly of the utility model is completed, the gypsum board 14 is fixed to the C-shaped keel 9 by bolts through the gypsum board 14 on the C-shaped keel 9, which is more beautiful and improves the protective effect.

[0024] In this embodiment: when installing the standardized opening protection device at the position of the elevator door opening, first, use expansion bolts to pass through the fixing holes 10 to fix the C-shaped keel 9 to the upper, lower, left and right sides of the elevator door opening. After the C-shaped keel 9 is fixed, align the longitudinal rod 1 and the transverse rod 2 with the C-shaped keel 9, and install the longitudinal rod 1 and the transverse rod 2 on the C-shaped keel 9 according to the size that the distance between the longitudinal rods 1 is less than 1 meter and the distance between the transverse rods 2 is less than 0.3 meters. During installation, the construction worker holds the top rod 3 with one hand and inserts his fingers into the handle 6. The buffer pad 12 on the handle 6 protects the construction worker's hand, making the contact between the construction worker's hand and the handle 6 more flexible. Then, the handle 6 is moved in the directions of both sides of the top rod 3. The handle 6 moves outward to drive the slider 7 and the tooth block 5 to move outward. The slider 7 prevents the handle 6 from completely moving the tooth block 5 out of the top rod 3. The guide block 13 on the slider 7 enables the slider 7 to move more stably in the top rod 3. When the tooth block 5 is separated from the rack 4 by the handle 6, the construction worker maintains the holding state at this time and then moves his hand toward the C-shaped keel 9 to drive the handle 6 to move. The movement of the handle 6 drives the tooth block 5 separated from the rack 4 to move. The movement of the tooth block 5 drives the top rod 3 to move toward the C-shaped keel 9 until the end of the top rod 3 is inserted into the C When the C-shaped keel 9 is at its deepest point, the handle 6 is released, and the spring 8 drives the handle 6 to reset. The reset of the handle 6 drives the tooth block 5 to engage with the rack 4 again to fix the position of the push rod 3. The limit block 11 at the end of the push rod 3 allows the push rod 3 to be inserted into the fixing hole 10 when it is inserted into the deepest point of the C-shaped keel 9 to prevent the push rod 3 from being displaced. The holding method enables the construction personnel to better operate the push rod 3 with one hand, and the other hand can hold objects such as ladders to protect themselves. The above method is repeated to insert the push rods 3 at both ends of each longitudinal rod 1 and transverse rod 2 into the C-shaped keel 9 to complete the protection of the elevator door opening. Through the gypsum board 14 on the C-shaped keel 9, after the utility model is assembled, the gypsum board 14 is fixed to the C-shaped keel 9 by bolts, which is more beautiful and improves the protection effect.
