Description

Technical Field

[0001] The invention relates to the technical field of nuclear power construction, and in particular to an attached passage device for a nuclear island construction elevator. Background Art

[0002] At present, in the nuclear power construction field, during the construction of the nuclear island, personnel mainly rely on construction elevators to go up and down. Because the installation of the construction elevator is restricted by the environment, the supporting wall of the construction elevator cannot be normally connected to the nuclear island shell in the early and middle stages of construction and cannot be put into use. Only a box-type revolving ladder is used for passage, and the efficiency of personnel passage is low. The construction elevator is only installed in the middle and late stages of construction, and its use has strong limitations. At the same time, after the construction elevator is installed, in order to avoid power outages that cause obstruction of personnel passage, it is still necessary to continue to set up artificial passages. In order to effectively solve the above problems, it is necessary to develop a nuclear island construction elevator attached passage device that can be used with the construction elevator. Summary of the invention

[0003] In view of the defects existing in the prior art, the object of the present invention is to provide an attachment passage device for a nuclear island construction elevator.

[0004] The present invention is achieved through the following technical solutions:

[0005] A nuclear island construction elevator attachment passage device, comprising a plurality of vertical standard sections connected in combination, characterized in that a connecting mechanism for connecting with a construction elevator support wall is provided on the vertical standard section;

[0006] A ladder is also provided inside the vertical standard section.

[0007] The nuclear island construction elevator attachment passage device provided in this solution solves the problem that the construction elevator is restricted by the installation environment during the nuclear island construction process.

[0008] In the traditional nuclear island construction process, box-type revolving ladders are usually used for passage in the early and middle stages. Elevators are only installed in the middle and late stages of construction, and corresponding artificial passages are still required to avoid power outages that cause obstruction to personnel passage. This construction method is seriously inefficient.

[0009] The nuclear island construction elevator attached passage device described in this scheme effectively solves this problem. The device is assembled from a number of vertical standard sections, and the number of vertical standard sections can be flexibly selected according to the requirements of the building construction height. The construction elevator support wall is installed on the vertical standard section through a connecting structure, which can break through the limitations of the installation environment and can be installed and used in the early stage of nuclear island construction. This device is also suitable for the installation of elevators during the construction of some high-rise buildings with unconventional shapes. At the same time, there is a ladder inside the vertical standard section, which can be used for the passage of personnel during power outages, eliminating the inconvenience of setting up an additional artificial passage on the basis of installing the elevator in conventional technology, and has high social and economic benefits.

[0010] Furthermore, the connecting mechanism includes a crossbeam and a buttress connecting piece; the buttress connecting piece is arranged on the crossbeam and is used to be connected to the buttress of the construction elevator.

[0011] Furthermore, the vertical standard section also includes supporting columns and diagonal braces, and the diagonal braces are cross-arranged; the two ends of the crossbeam are respectively connected to the supporting columns on both sides, and the crossbeam passes through the intersection of the two diagonal braces.

[0012] Furthermore, each vertical standard section is combined and connected by connecting bolts. The use of bolt connection can facilitate the assembly and disassembly of each vertical standard section.

[0013] Furthermore, a walking passage is provided on the side of the vertical standard section, and the walking passage is used to connect the vertical standard section with the building.

[0014] Furthermore, the walking channel is installed on the vertical standard section through connecting ear plates.

[0015] Furthermore, the ladder is arranged at an angle, connecting the bottom and the top of the vertical standard section. The ladder is arranged at an angle at a certain angle, which is more conducive to the passage of operators and has higher passage efficiency than the vertical arrangement.

[0016] The installation process of the above-mentioned nuclear island construction elevator attachment passage device is as follows:

[0017] Step 1: According to the building construction height requirements, select a suitable number of vertical standard sections, assemble and fix them to the ground using connecting bolts;

[0018] Step 2: Install and connect the walking passage connected to the building with the vertical standard section through the connecting ear plate;

[0019] Step 3: During the installation of the construction elevator, connect the buttress of the elevator with the buttress connection hole on the vertical standard section beam;

[0020] Step 4: Repeat steps 2 and 3 to complete the assembly installation of the entire device in sequence according to the set height.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The nuclear island construction elevator attachment passage device provided by the present invention can be applied to the installation of construction elevators during the construction of nuclear islands and some high-rise buildings with unconventional shapes.

[0023] The elevator is connected to the building through this device, which not only ensures the safe use of the construction elevator, but also improves the efficiency of people going up and down the building; and the device has a simple structure and is easy to install, which can improve work efficiency, has high social and economic benefits, and can be widely used and promoted.
