Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a sill placement point structure for an elevator door. Background Art

[0002] Elevators are an indispensable part of modern buildings, and the safety of elevators is also an issue we are very concerned about. Among them, the requirements for the clearance and firmness of the elevator door sill are one of the important indicators of elevator safety.

[0003] During the construction of the main body of the elevator shaft, the reservation of the placement point of the elevator door sill is often ignored. Later angle steel reinforcement is often used to fill the gap between the elevator floor door and the main structure. The elevator sill is a position where people frequently step on it. The angle steel reinforcement method has the problem of loose fixation and loose combination with the civil decoration layer. After long-term stepping, it will appear uneven, posing a safety hazard. In view of this situation, an elevator door sill placement point structure is invented, which is a reinforced concrete structure. It can be constructed together with the main structure of the elevator shaft and can be effectively combined with the subsequent decorative layer. It is both stable and safe. Utility Model Content

[0004] The utility model aims to provide a structure for placing a sill of an elevator door to solve the problems mentioned in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an elevator door sill resting point structure, which is arranged on the elevator shaft and used to protect the floor, comprising:

[0006] A door frame shell is arranged on the elevator shaft and is used to increase the strength of the floor.

[0007] Preferably, the height of the door frame shell is consistent with the height of the elevator shaft, ensuring that the elevator in the elevator shaft will not be knocked during use.

[0008] Preferably, the door shell includes a through-length rod arranged in the elevator shaft, and a fixing rod arranged on the through-length rod for fixing the through-length rod, and the door shell is a floor in front of the elevator.

[0009] Preferably, the number of the through-length rods is not less than two, the number of the fixed rods is not less than five, all of the through-length rods and the fixed rods are connected and fixed to strengthen the quality of the door shell, and all of the through-length rods and the fixed rods are connected to form a trapezoid to increase stability.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the elevator door sill resting point structure improves the quality of the threshold resting point by changing the shape of the door rafter and adding steel bars such as full-length rods and fixed rods therein, thereby increasing its service life, and does not cause the problem mentioned in the background technology that people frequently step on it, and the door sill will become uneven after stepping on it for a long time, which poses a safety hazard.

[0016] 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.

[0017] like Figure 1 As shown, the utility model provides a technical solution: an elevator door sill resting point structure, which is arranged on the elevator shaft 1 and is used to protect the floor, comprising: a door sill shell 2, which is arranged on the elevator shaft 1 and is used to increase the strength of the floor.

[0018] like Figure 2As shown, the height of the door shell 2 is consistent with the height of the elevator shaft 1, ensuring that the elevator in the elevator shaft 1 will not be knocked when in use, thereby reducing the gap between the door shell 2 and the elevator, and the door shell 2 protrudes to the inside of the elevator. The shape of the door shell 2 is triangular, which is used to enhance the stability of the door shell 2. The door shell 2 is a reinforced concrete structure. The door shell 2 includes a through-length rod 4 set in the elevator shaft 1. The length of the through-length rod 4 is the same as the width of the door opening. The steel bars are all ribbed steel bars with a diameter of 8 mm, and are set in the through-length rod 4. The long rod 4 is used to fix the fixing rod 3 of the full-length rod 4. The fixing rod 3 is arranged on the steel bar with a spacing of 200mm, and then the full-length rod 4 is arranged. The door shell 2 is the floor in front of the elevator. The number of the full-length rods 4 is not less than two, and the number of the fixing rods 3 is not less than five. The two full-length rods 4 are arranged in parallel up and down, and then the two full-length rods 4 are ring-fixed and welded through five fixing rods 3. All the full-length rods 4 and the fixing rods 3 are connected and fixed to strengthen the quality of the door shell 2. All the full-length rods 4 and the fixing rods 3 are connected into a trapezoid to increase stability.

[0019] As shown above, in this embodiment, during the main construction of the elevator shaft 1, a door sill shell 2 is arranged on the lower side of the opening of the elevator shaft 1, which is fastened securely by means of a fixing rod 3 and a through-length rod 4, a formwork is set, and concrete is poured together with the main structure. The finished surface elevation of the door sill shell 2 is 30 mm lower than the elevation of the side structure surface. In this way, a reinforced concrete elevator door sill resting point structure is formed, which can reduce the gap between the elevator floor door and the structure and is very firm without any safety hazards.

[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
