Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of construction elevator joint, especially point to a kind of platform connecting device for construction elevator and floor. BACKGROUND

[0002] ‌The connecting relationship between construction elevator and floor is mainly realized through connecting plate, and the connecting plate is the bridge between construction elevator and floor, mainly plays the role of supporting and stabilizing elevator, it not only bears the weight of elevator itself, but also bears dynamic load in transportation process. Common connecting plate types include cantilever type, wall attachment type and self-lifting type, and the cantilever type connecting plate is suitable for the case that the elevator cannot be fixed on the floor outer wall;The wall attachment type connecting plate is fixed on the floor outer wall to provide support;The self-lifting type connecting plate is automatically lifted with the lifting of the elevator. When selecting connecting plate, the model of construction elevator, floor height, structural characteristics and site environment and other factors need to be considered. Regardless of which connecting plate is used, a certain gap between construction elevator and floor needs to be ensured, which not only easily causes tools or building materials to fall and injure workers on site, but also may cause the risk of stepping on the passengers and causing crush injury. Therefore, how to handle the gap is a key factor to ensure the safety of construction elevator and cargo.

[0003] In the prior art, the commonly used methods for handling the gap between construction elevator and floor mainly include the following.

[0004] I. Directly filling the gap between elevator and floor: this is the simplest and most common solution, and the specific operation is to install a layer of building board or rock wool board at the bottom of the elevator, and then seal the edge with waterproof material. This method has low cost, but moisture and fireproofing problems need to be considered.

[0005] II. Install foam filling material: foam filling material has the functions of shock absorption, sound insulation and heat preservation, and is simple to use, only need to spray foam material between the gap. However, it needs to be noted that the density of foam material itself is relatively light and can be compressed, so it is necessary to reasonably select foam source.

[0006] III. Install stair closing steel plate: this method is more beautiful, and the size of closing steel plate can be made according to actual situation, if the floor needs to be used later, the closing steel plate can be directly removed. However, this method is more complicated, needs professional construction personnel to construct, and will increase the cost of construction.

[0007] Due to the above processing method of the gap between the construction elevator and the floor, there are obvious deficiencies, therefore, the utility model patent with the authorization announcement date of 2020.09.25 and the authorization announcement number of CN 211569828 U discloses a construction elevator gap compensation device, which comprises a compensation head and a compensation sleeve, one side of the compensation sleeve towards the building is installed to the bottom of the construction elevator, and the opening of the compensation sleeve is horizontally outward; the compensation head is slidingly connected to the compensation sleeve, a first spring is arranged in the compensation sleeve, and the first spring pushes the compensation head to extend out of the compensation sleeve; the left and right ends of the compensation head are provided with inclined surfaces, so that the cross section of the compensation head is isosceles trapezoidal.

[0008] The technical solution disclosed by the above utility model patent fills the gap between the elevator and the building in a specific case, and can be applied to different distances between the elevator and the building. That is, when the elevator door is opened, the compensation head extends out of the compensation sleeve under the pushing of the first spring, thereby abutting against the building to compensate the gap and improve safety; when the elevator door is closed, the bottom of the elevator door pushes the inclined surfaces on both sides of the compensation head, so that the compensation head retracts into the compensation sleeve. However, there are the following deficiencies: first, it is only applicable to the construction elevator with horizontally split doors, and cannot be applied to the construction elevator with lifting type opening and closing; second, it completely depends on the precise control of the construction elevator, and the lifting and stopping of the construction elevator depend on the observation and manual operation of the elevator operator. Only when the construction elevator stops at the position corresponding to the height of the compensation head and the floor, the compensation head can abut against the target position, otherwise, the height difference between the compensation head and the floor will be generated, which not only makes it difficult for the construction trolley to pass between the construction elevator shaft and the floor, but also reduces the safety of the workers passing.

[0009] In summary, it is urgent to design a platform connecting device between the construction elevator and the floor, which is applicable to construction elevators with various door opening modes, and can compensate the horizontal gap and the height difference between the construction elevator and the floor.
