Description

Technical Field

[0001] This utility model belongs to the field of construction machine technology, and in particular relates to a wall-mounted guide rail for an inner and outer shell construction machine of the nuclear island BRX plant that can avoid interference. Background Technology

[0002] The nuclear island buildings of a power plant are generally divided into several types based on their process requirements: reactor building (BRX), nuclear fuel building (BFX), safety building (BSX), reactor gantry building (BRP), nuclear auxiliary building (BNX), radioactive waste treatment building (BWX), access building (BAX), additional cooling water and nuclear island fire water building (BEJ), and diesel generator building (BDX). The reactor building (BRX), in particular, has a very high design strength and durability for its concrete.

[0003] The reactor building (BRX), also known as the nuclear island BRX building, is specifically designed with a cylindrical outer shell on all sides and a dome on top. Construction typically involves building the inner and outer cylindrical shells first, followed by the dome. Due to the massive size of the nuclear island BRX building and the high strength requirements for the outer shell, traditional scaffolding methods are slow, require large frames, and are inconvenient for practical operation. This technical solution addresses this issue by using climbing formwork to lift and lower the formwork system during the inner and outer shell construction. The nuclear island construction machine is divided into several modules according to the nuclear island's structure, enabling rapid assembly and lifting on-site, effectively solving pain points related to safety, quality, schedule, and personnel management during construction. Furthermore, the nuclear island construction machine can interfere with embedded parts on the nuclear island shell when pre-embedding screws and climbing cones. This technical solution proposes a wall-mounted guide rail that avoids this interference, effectively resolving the interference problem. Utility Model Content

[0004] This utility model provides an interference-avoiding wall-mounted guide rail for the construction machine of the inner and outer shell of the nuclear island BRX plant. The wall-mounted guide rail includes a web plate, a guide rail panel, a template panel, and a connecting plate. The steel template has connecting holes for installing pre-embedded climbing cones, and the guide rail panel is designed with ladder stops. When the nuclear island construction machine installs the wall-mounted guide rail, the inner and outer wall-mounted guide rails are connected to the climbing cones with screws, and the guide rails are connected to the climbing cones with bolts. The screws, climbing cones, and bolts serve as the load-bearing supports for the wall-mounted guide rail. Several sets of pre-embedded parts are installed on each set of wall-mounted guide rails, with one set on each side of each set. When the pre-embedded screws and climbing cones interfere with the pre-embedded parts such as steel bars and steel pipes on the shell, the position of the screws and climbing cones can be adjusted because of the connecting holes on the template panel of the wall-mounted guide rail, thus avoiding interference components on the shell. In summary, this solves the problems in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model provides an interference-avoiding wall-mounted guide rail for the construction of the inner and outer shell of a nuclear island BRX plant, comprising a vertically arranged web, guide rail panels and template panels arranged on both sides of the web, and connecting plates located at the upper and lower ends of the web.

[0007] The width of the template panel is greater than that of the guide rail panel. Pre-embedded climbing cone connection holes are symmetrically and equally spaced on both sides of the web on the surface of the template panel. Pre-embedded climbing cones are installed in the pre-embedded climbing cone connection holes by bolts. Template panels are symmetrically arranged on both sides of the outer wall structure of the containment vessel and are connected to the pre-embedded climbing cones on both sides by pre-embedded threaded rods.

[0008] Furthermore, the guide rail panel is designed to work in conjunction with the suspension shoe of the building construction machine; the surface of the guide rail panel is provided with stair grooves at equal intervals that match the load-bearing tongue of the suspension shoe.

[0009] Furthermore, a pad is provided at the location of the pre-embedded climbing cone connection hole.

[0010] Furthermore, the template panel is provided with side steel template connecting plates on both sides, and the width of the upper and lower ends of the side steel template connecting plates is consistent with the width of the protruding part of the connecting plate.

[0011] Furthermore, the connecting plate has a T-shaped structure.

[0012] Furthermore, the side steel formwork connecting plate is provided with side steel formwork connecting holes at equal intervals on its surface.

[0013] Furthermore, reinforcing ribs are provided between the template panel, the side steel template connecting plate, and the web plate.

[0014] The present invention has the following advantages over the prior art:

[0015] (1) The wall-mounted guide rail of this technical solution includes a web plate, a guide rail panel, a template panel and a connecting plate. The steel template has a connection hole for installing the pre-embedded climbing cone, and the guide rail panel is designed with a ladder. When the nuclear island construction machine installs the wall-mounted guide rail, the inner and outer wall-mounted guide rails are connected to the climbing cone with a screw rod, and the guide rail and the climbing cone are connected with bolts. The screw rod, climbing cone and bolt serve as the force support for the wall-mounted guide rail. Several sets of pre-embedded parts are installed on each set of wall-mounted guide rails, and there is one set of pre-embedded parts on the left and right sides of each set. When the pre-embedded screw rod and climbing cone interfere with the pre-embedded parts such as steel bars and steel pipes on the shell, the position of the screw rod and climbing cone can be adjusted because there are connection holes on the template panel of the wall-mounted guide rail, so as to avoid interference parts on the shell.

[0016] (2) The wall-mounted guide rail structure of this technical solution is simple, has high structural strength, and is easy to apply and promote.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] Please see Figure 1-10 As shown, the present invention provides a wall-mounted guide rail for the construction of the inner and outer shell of the nuclear island BRX plant that can avoid interference. It includes a vertically arranged web plate 11, guide rail panels 12 and template panels 17 arranged on both sides of the web plate 11, and connecting plates 13 located at the upper and lower ends of the web plate 11. All components of the wall-mounted guide rail are made of steel. The connecting plate 13 has a T-shaped structure.

[0034] The template panel 17 is provided with side steel template connecting plates 14 on both sides. The width of the upper and lower ends of the side steel template connecting plates 14 is the same as the width of the protruding part of the connecting plate 13 on the side. The side steel template connecting plates 14 are provided with side steel template connecting holes at equal intervals on the surface. It can assist in the installation of the template and is used for concrete pouring of the outer wall structure 7 of the containment building.

[0035] The template panel 17 is wider than the guide rail panel 12. Pre-embedded climbing cone connection holes 16 are symmetrically and equally spaced on both sides of the web plate 11 on the surface of the template panel 17. Pre-embedded climbing cones 21 are installed in the pre-embedded climbing cone connection holes 16 by bolts 22. The template panels 17 are symmetrically arranged on both sides of the outer wall structure 7 of the containment vessel and are attached to the surface. The pre-embedded climbing cones 21 on both sides are connected by pre-embedded threaded rods 2. The pre-embedded climbing cones 21 are existing technology and have threads that cooperate with the pre-embedded threaded rods 2. The pre-embedded climbing cones 21 are locked and fixed to the template panel 17 by bolts 22.

[0036] The guide rail panel 12 is matched with the suspension shoe 41 of the building machine; the surface of the guide rail panel 12 is provided with stair grooves at equal intervals that match the load-bearing tongue block of the suspension shoe 41.

[0037] A pad 15 is provided at the location of the pre-embedded climbing cone connection hole 16.

[0038] Among them, the template panel 17, the side steel template connecting plate 14 and the web plate 11 are provided with reinforcing connecting ribs 18 for structural reinforcement.

[0039] like Figure 7-10 As shown, the island building machine's jacking mechanism mainly consists of jacking cylinder 4, steel formwork, wall-mounted guide rails, climbing shoes 41, triangular lattice columns 3, top steel platform 5, and suspension arms 6.

[0040] The climbing system consists of two sets of wall-mounted lifting guide rails installed on both the inner and outer sides of the nuclear island's outer shell. Pre-embedded climbing cones 21 are mounted on the two sets of lifting guide rails, and the pre-embedded climbing cones 21 are connected by pre-embedded threaded rods 2. The wall-mounted lifting guide rails are divided into upper and lower parts, connected by bolts. In this specific example, the entire mechanism consists of four sets of lifting guide rails. Tripods 31 for the inner and outer machine positions and lifting cylinders 4 are installed on the lifting guide rails.

[0041] Anti-interference wall-mounted guide rail structure: guide rail panel 12, steel formwork panel 17, side steel formwork connecting plate 14, web plate 11 between the lifting guide rail and the steel formwork, and upper and lower lifting guide rail connecting plate 13; the steel formwork has 200-module connecting holes 16 for installing pre-embedded climbing cones 21, and there are 20mm thick pads 15 on the outside of the holes. The steel formwork is designed with load-bearing blocks, and the lifting guide rail panel is designed with 200-module ladder grooves.

[0042] When installing the wall-mounted guide rails on the nuclear island construction machine, the inner and outer wall-mounted guide rails are connected to the pre-embedded climbing cones 21 using pre-embedded threaded rods 2, and the guide rails are connected to the pre-embedded climbing cones 21 using B7 high-strength flange bolts 22.

Four sets of pre-embedded parts are installed on each set of wall-mounted guide rails, with one set on each side of each set. When the pre-embedded threaded rods 2 and pre-embedded climbing cones 21 interfere with the pre-embedded parts such as steel bars and steel pipes on the outer shell, the position of the pre-embedded threaded rods 2 and pre-embedded climbing cones 21 can be adjusted because there are 200-module connection holes 16 on the template panel of the wall-mounted guide rails. This can avoid interference components on the outer shell.
