Examples

Referring to fig. 1 to 4, the simple safety protection device for prefabricated capping beam includes: the fixing component 1 is detachably arranged on the beam head of the prefabricated bent cap, the upright rods 2 are arranged on two sides of the fixing component 1, and the protection rope 3 is connected between the upright rods 2 of the beam heads at two ends of the prefabricated bent cap;

the fixing assembly 1 comprises a longitudinal beam 101, two cross beams 102 fixedly connected with two ends of the longitudinal beam 101 respectively, a sleeve 103 in sliding connection with the cross beams 102, a fastening bolt 104 arranged on the sleeve 103, and a limiting rod 105 connected between the two cross beams 102 through the sleeve 103;

in this embodiment, referring to fig. 4, the installation process of the protection device is as follows, the fixing component 1 is installed on the beam head 5 of the prefabricated capping beam 4, specifically, the longitudinal beam 101 is firstly attached to the end surface of the beam head 5, then the two cross beams 102 are respectively attached to the two side surfaces of the beam head 5, then the position of the movable sleeve 103 on the cross beam 102 is located, and the fastening bolt 104 is screwed, so that the limiting rod 105 is just attached to the other end surface of the beam head 5, and thus the rectangular frame formed by enclosing the longitudinal beam 101, the two cross beams 102 and the limiting rod 105 is fixed on the beam head 5 (i.e. the fixing component 1 is fixed on the beam head 5); then, the protection rope 3 is pulled, and the protection rope 3 is connected and fixed between the upright stanchions 2 of the beam heads at the two ends of the prefabricated bent cap in a penetrating way, so that the installation of the protection device is completed; when an operator works on the upper beam, the construction operation can be carried out only by tying the safety rope on the protection rope 3, so that the personal safety is ensured, and the construction efficiency is not influenced; in addition, since the sleeve 103 is slidably connected to the beam 102, adjusting the position of the sleeve 103 on the beam 102 allows the fixing assembly 1 to be adapted to beam heads of different sizes.
