Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a construction shaft for construction engineering. Background Art

[0002] In some underground projects, in order to ensure the normal progress of underground projects, vertical shafts are needed to assist in the transportation of materials and to provide ventilation. However, the current vertical shafts cannot ensure the safe escape of construction workers when danger occurs.

[0003] In order to solve the above problem, patent number CN202222382028.9 discloses a construction shaft for construction engineering. When the construction workers take emergency shelter, they climb on the ladder 104, select the nearest shelter room 105, and contact the arc plate 110. The distance between the sliding plate 109 and the shelter room 105 is related to the size of the construction workers. According to the size of the construction workers, the sliding plate 109 slides upward. At this time, the roller 108 rotates and moves on the sliding rail 107 to change the distance between the sliding plate 109 and the shelter room 105, so that the construction workers can enter the shelter room 105 for emergency shelter. After the construction workers enter the shelter room 105, the sliding plate 109 slides downward under the action of its own gravity. The buffer plate 112 is provided on the placement block 111, and the buffer plate 112 buffers the impact force of the sliding plate 109.

[0004] The construction shaft disclosed in the above patent uses an up-and-down sliding plate to block the opening. The opening is relatively small and danger often occurs in an instant. The workers cannot quickly slide the sliding plate up by hand and then drill into the shelter room from the opening. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4 The foldable door body 3 is hinged to the upper and lower parts of the escaping compartment 1 by hinges 2, and the foldable door body 3 is hinged to the upper and lower parts of the escaping compartment 1 by hinges 2.

[0021] Furthermore, the outer limit assembly includes a second outer top baffle 14 fixedly installed on the lower part of the outer side wall of the door body 3, the second outer top baffle 14 is placed at the lower part of the first outer top baffle 13, and the first outer top baffle 13 is fixedly installed on the top of the bottom outer baffle 5, and is limited on the outside to prevent the door body 3 from being lifted outward and opened at will; further, the bottom outer baffle 5 can be removably installed at the bottom of the opening of the vertical shaft escape chamber 1 through the screw holes and bolts 6 at its left and right ends, so as to facilitate the rapid rescue of rescue personnel outside; further, a plurality of air holes 7 are opened on the back of the vertical shaft escape chamber 1 for convenient ventilation; further, a tool box 8 is fixedly installed in the vertical shaft escape chamber 1 for convenient tool placement; further, a storage stool 9 is fixedly installed in the middle part of the inner side wall of the vertical shaft escape chamber 1, and a stool cover 10 is hinged at the top opening of the storage stool 9, so that the escapee can sit down and place some food, water and other items.

[0022] In the present scheme, when in use, the construction shaft opening of the utility model is hinged with a foldable door body 3 through a hinge 2. When emergency escape is needed, the staff can quickly enter the shaft escape chamber 1 by pushing the door body 3 inwards, and the escape probability is high. In addition, an outer limit assembly and a slidable inner limit assembly are provided, and the protective effect is still very strong. When not in use, the two T-shaped sliding blocks 15 are located in the middle and are separated from the limit seat 11. When an emergency occurs, the staff hits the door body 3 with their bodies, and the door body 3 can be pushed inwards along the top hinge 2 in an instant. The door body 3 is formed by a plurality of transverse pieces 4 hinged at the ends by the hinge 2. At this time, it can be bent to a certain extent, so that the staff can quickly fall into the vertical shaft escape chamber 1, and then the staff can use the slidable internal limit assembly, that is, pull the pull ring 12 to slide the two T-shaped sliding blocks 15 along the T-shaped slide groove 16 to the left and right ends respectively, until they are inserted into the limit seat 11, to prevent the door body 3 from being smashed open by rocks outside. Because the second outer top baffle 14 at the lower part of the outer end of the door body 3 is blocked by the first outer top baffle 13, the door body 3 is difficult to be pushed outward, and it can be safely avoided. When the internal staff is trapped for too long and unconscious and it is difficult to open the door body 3 from the inside by themselves, the rescuers remove the bolts 6 and the bottom outer baffle 5 to carry out rescue.
