A foldable light surface collecting maintenance integrated platform attached to a dam panel slip form

Abstract

This invention discloses a foldable, lightweight integrated platform for surface finishing and curing attached to a dam panel slipform. The platform is hinged to the slipform, enabling it to fold and flip. It can be directly integrated with the slipform, reducing the overall volume to achieve overall slipforming and avoiding repeated disassembly and assembly. The telescopic folding fence and sunshade / rain shelter can be almost completely folded and stored, eliminating the need for secondary installation after the slipform has risen 2-3 meters. This does not restrict the normal slipforming process and significantly reduces bolt connections and on-site welding work. When used for single-panel pouring in skip-slot construction, the platform can be folded and stored as a whole, and directly hoisted to the next panel with the slipform, eliminating the need for disassembly, transportation, and reassembly. This greatly simplifies the process and improves the efficiency of multi-panel construction.

Description

Technical Field

[0001] This invention relates to the field of slipform construction technology for dam concrete panels, and in particular to a foldable, lightweight integrated platform for surface finishing and curing attached to dam panel slipform construction. Background Technology

[0002] The concrete face construction of rockfill dams in hydropower stations typically employs trackless slipform technology. A finishing platform is usually attached behind the main slipform, serving as a key auxiliary structure for facilitating the finishing and smoothing of the freshly poured concrete. The finishing platform is located at the rear of the slipform and can be raised synchronously with the slipform or raised separately by a dedicated lifting mechanism.

[0003] In the slipform construction of dam concrete panels, the slipform slides continuously along the slope, allowing for simultaneous pouring and demolding. After the concrete is removed from the slipform, it must be immediately hand-finished and smoothed to prevent early cracking and improve impermeability and durability. The finishing platform provides a safe and stable operating space for workers, ensuring that the demolded concrete surface can be promptly finished to meet the requirements of a smooth and dense finish. The finishing platform is typically fixed to the end of the slipform truss. Curing is generally carried out after concrete pouring, either by installing perforated pipes on the dam crest or by manual water spraying.

[0004] The disadvantages of existing technology are: 1. Significant workload in disassembly and assembly: Due to the obstruction of the horizontal toe plate at the bottom of the panel, traditional finishing platforms are generally only ready for installation after the slipform has been raised 2-3 meters. The numerous bolt connections or on-site welding operations are extremely labor-intensive and significantly hinder the normal slipform raising process. Some projects use a separate lifting system for pulling the finishing platform, which requires additional dam crest traction equipment, reducing the working space on the dam crest.

[0005] 2. Low site transfer efficiency: In dam projects, multiple panels need to be poured in stages. When a panel is completed in slipform construction and needs to be hoisted to the next panel, the traditional extended fixed platform needs to be transported separately to the bottom of the slipform before installation, which is a cumbersome process.

[0006] 3. Curing: The traditional curing method for the panel is to lay curing pipes on the top of the dam after the slipform is completed, and the curing pipes flow from the top to the entire panel for curing. However, the slipform time for a single panel is generally 2-4 days. The bottom of the concrete that has already begun to set cannot be cured in time or can be cured manually, which is labor-intensive and has poor curing effect.

[0007] 4. Inconvenient storage: Slipforms with large fixed platforms require large warehouses or storage yards for storage, which increases operating costs.

[0008] Therefore, it is necessary to develop a foldable, lightweight integrated maintenance platform for dam panel slipforming to solve the above problems. Summary of the Invention

[0009] The purpose of this invention is to design a foldable, lightweight, integrated surface finishing and maintenance platform attached to the slipforming of dam panels in order to solve the above-mentioned problems.

[0010] The present invention achieves the above objectives through the following technical solutions: A foldable, lightweight, integrated maintenance platform for dam panel slipforming includes: Platform frame; the first end of the platform frame is hinged to the sliding mold through multiple sliding mold and platform hinge devices; in the working state, the first end of the platform frame is pressed against the lower end of the sliding mold, and the platform frame is fixed in posture relative to the sliding mold. Telescopic folding fence; the first end of the telescopic folding fence is hinged to the second end of the platform frame; Sunshade and rainproof awning; the sunshade and rainproof awning is installed on the telescopic and folding fence and is used to provide sunshade and rain protection for construction workers working in the working position on the platform frame; Integrated maintenance structure; the integrated maintenance structure is installed on the second end of the platform frame.

[0011] Specifically, the platform frame includes a square steel main frame, a sliding formwork side angle steel frame, and a patterned steel plate platform. The first end of the sliding formwork side angle steel frame is connected to one end of the square steel main frame, and the sliding formwork side angle steel frame is perpendicular to the square steel main frame. The first end of the patterned steel plate platform is connected to the other end of the square steel main frame, and the patterned steel plate platform is in a horizontal state during operation.

[0012] Furthermore, the platform frame also includes obliquely welded angle steel and triangular reinforcing steel plates. The obliquely welded angle steel is connected to the upper and lower crossbars of the angle steel frame on the slipform side, and the two sides of the triangular reinforcing steel plates are connected to the square steel main frame and the angle steel frame on the slipform side, respectively.

[0013] Specifically, the telescopic folding fence includes multiple fence foot baffles, multiple square steel guardrail main frames, and multiple horizontal square steel guardrail frames. The multiple fence foot baffles are installed side by side above the second end of the patterned steel plate platform. The fence foot baffles are formed into hollow cuboids. The upper end of the fence foot baffles and the first side facing the square steel main frame are both open. The first end of the square steel guardrail main frame is placed inside the fence foot baffles. The square steel guardrail main frame is hinged to the fence foot baffles. The horizontal square steel guardrail frames are installed between the second ends of two adjacent square steel guardrail main frames. Two inclined welded round steel guardrails are installed between two adjacent square steel guardrail main frames. The two welded round steel guardrails are arranged crosswise.

[0014] Furthermore, the telescopic folding fence also includes multiple fence locking bolt and nut assemblies, each consisting of a bolt and a nut. Each fence foot baffle has two first limiting holes, which are positioned opposite each other on the two side walls of the fence foot baffle. A positioning hole is provided at the first end near the main frame of the square steel fence. When the main frame of the square steel fence rotates downwards to abut against the patterned steel plate platform, the bolt shank passes through the two first limiting holes in sequence and connects with the nut. The bolt shank is used to lock the main frame of the square steel fence upwards. When the main frame of the square steel fence rotates upwards to a vertical position, the bolt shank passes through one first limiting hole, the positioning hole, and the other first limiting hole in sequence and connects with the nut. The bolt shank locks the main frame of the square steel fence in its locked position.

[0015] Specifically, the sunshade and rainproof awning includes multiple steel frames with telescopic guardrail channels, multiple sets of fixing bolts and nuts for the roof keel, multiple roof keel fixing brackets, multiple foldable roof keels, multiple foldable hooks, and multiple awnings. The steel frames with telescopic guardrail channels are formed into hollow cuboids. The upper end, lower end, and first side facing the square steel main frame of the steel frames with telescopic guardrail channels are all open. The steel frames with telescopic guardrail channels can slide up and down inside the square steel guardrail main frame. The first end of the foldable roof keel extends into the upper end of the steel frames with telescopic guardrail channels and is hinged to the steel frames. The width of the foldable roof keel is smaller than the inner width of the steel frames with telescopic guardrail channels. The foldable keel of the canopy is a hollow cuboid. The top, bottom, and first side of the foldable keel are all open. The first end of the foldable keel fixing bracket extends into the interior from the first side of the foldable keel and is hinged to the foldable keel. The second end of the foldable keel fixing bracket is detachably connected to the middle of the guardrail expansion groove steel frame through the foldable keel fixing bolt and nut assembly. Each foldable keel has multiple foldable hooks inside. A canopy is set between two adjacent foldable keels. The two ends of the canopy are connected to the foldable hooks of the two foldable keels respectively. The canopy is placed directly above the patterned steel plate platform.

[0016] Furthermore, the sunshade and rainproof canopy also includes multiple spring ball plungers. The spring ball plungers are installed below the side wall of the steel frame of the guardrail expansion channel. Correspondingly, spring ball plunger holes are reserved at the top and bottom of the side wall of the main frame of the square steel guardrail, respectively. When the steel frame of the guardrail expansion channel is fully retracted into the main frame of the square steel guardrail, the spring ball plungers engage with the reserved spring ball plunger holes at the bottom of the main frame of the guardrail. When the steel frame of the guardrail expansion channel extends out of the main frame of the square steel guardrail, the spring ball plungers engage with the reserved spring ball plunger holes at the top of the main frame of the guardrail.

[0017] Furthermore, the length of the ceiling keel fixing bracket is less than or equal to the first length, which is the length from the second end of the ceiling foldable keel to the junction of the ceiling keel fixing bracket and the ceiling foldable keel. The length of the ceiling foldable keel is less than the second length, which is the length of the guardrail expansion groove steel frame extending out of the square steel guardrail main frame when the spring ball plunger engages with the reserved spring ball plunger hole on the upper part of the guardrail main frame.

[0018] Specifically, the sliding form and platform hinge device includes a sliding form connecting steel plate, a sliding form pin steel plate, a platform connecting bolt, a platform connecting nut, a platform fixing pin, a platform fixing steel plate, and a platform connecting steel plate. The sliding form connecting steel plate and the sliding form pin steel plate are installed side by side on the sliding form. The sliding form connecting steel plate has a first connecting hole and a second connecting hole arranged side by side. The first connecting hole is located near the end of the sliding form connecting steel plate. The sliding form pin steel plate has a third connecting hole. The platform fixing steel plate and the platform connecting steel plate are installed side by side on the second end of the side angle steel frame near the sliding form. The platform connecting steel plate has a fourth connecting hole and a fifth connecting hole arranged side by side. The connecting holes are located near the end of the platform connecting steel plate. The shank of the platform connecting bolt passes through the first connecting hole and the fourth connecting hole in sequence and then engages with the platform connecting nut. In the working state, the foldable lightweight surface curing platform flips downward under the action of gravity and is pressed against the lower end of the sliding mold by the side angle steel frame. In the non-working state, the foldable lightweight surface curing platform flips upward. After flipping into place, the platform fixing steel plate presses against the sliding mold. The second, fifth, and third connecting holes are coaxially distributed. The platform fixing pin passes through the second, fifth, and third connecting holes in sequence to lock the platform frame.

[0019] Specifically, a perforated steel pipe is installed below the second end of the square steel main frame. The length of the perforated steel pipe is the same as the length of the second end of the square steel main frame. The first end of the perforated steel pipe is connected to a curing water switch ball valve, and the second end of the perforated steel pipe is closed.

[0020] The beneficial effects of this invention are as follows: The foldable lightweight surface maintenance integrated platform and the slipform are hinged to achieve the flip-folding function. It can be directly connected to the slipform to reduce the overall volume to achieve the purpose of overall slip-raising, avoiding repeated disassembly and assembly. The telescopic folding fence and sunshade and rainproof canopy can be completely folded and stored without the need for secondary installation after the slipform has been raised 2-3 meters. It does not restrict the normal slip-raising of the slipform and greatly reduces the amount of bolt connection and on-site welding work.

[0021] After the single panel is completed in the skip-slot casting process, the platform can be folded up and transported directly to the next panel with the slipform, without the need for disassembly, transportation, and reassembly. This greatly simplifies the process and improves the efficiency of multi-panel construction.

[0022] The integrated curing structure slides up synchronously with the slipform, allowing for immediate water spraying and curing of the concrete immediately after demolding. This solves the problems of delayed curing by traditional dam crest pipes, low efficiency and poor results of manual curing, effectively preventing early cracking of concrete and improving the impermeability and durability of the panel.

[0023] The finishing work platform, safety guardrail, sunshade and rainproof canopy, and concrete curing structure are integrated into one unit, eliminating the need for separate protective and curing facilities, reducing labor input, and lowering the overall construction cost.

[0024] When not in use, the platform frame, telescopic folding fence, and sunshade and rainproof canopy can be completely retracted, significantly reducing the overall volume and eliminating the need for large storage yards / warehouses, thus reducing storage space costs.

[0025] The telescopic folding fence, sunshade and rainproof canopy, and platform frame flipping are all equipped with a multi-locking structure of bolts, spring ball plungers, and fixing pins, ensuring no shaking in operation and no loosening in non-operational state, thus guaranteeing the safety of construction personnel.

[0036] The main body of the slipform 1 is welded from materials such as square steel, angle steel, I-beams, and steel plates; the finishing platform is welded as a single piece.

[0037] like Figure 2 and 19 As shown, the platform frame 2.2 includes a square steel main frame 2.2.1, a sliding formwork side angle steel frame 2.2.2, and a patterned steel plate platform 2.2.3. The first end of the sliding formwork side angle steel frame 2.2.2 is connected to one end of the square steel main frame 2.2.1, and the sliding formwork side angle steel frame 2.2.2 is perpendicular to the square steel main frame 2.2.1. The first end of the patterned steel plate platform 2.2.3 is connected to the other end of the square steel main frame 2.2.1, and the patterned steel plate platform 2.2.3 is in a horizontal state during operation.

[0038] like Figure 2 and 19 As shown, the platform frame 2.2 also includes diagonally welded angle steel 2.2.4 and triangular reinforcing steel plate 2.2.5. The diagonally welded angle steel 2.2.4 connects the upper and lower crossbars of the angle steel frame 2.2.2 on the sliding form side, respectively. The two sides of the triangular reinforcing steel plate 2.2.5 connect the square steel main frame 2.2.1 and the angle steel frame 2.2.2 on the sliding form side, respectively. Both the diagonally welded angle steel 2.2.4 and the triangular reinforcing steel plate 2.2.5 are used to strengthen the overall structure of the platform frame 2.2.

[0039] like Figure 15-18 As shown, the telescopic folding fence 2.1 includes multiple fence foot baffles 2.1.1, multiple square steel fence main frames 2.1.2, and multiple horizontal square steel fence frames 2.1.5.

The two welded round steel fences 2.1.3 are arranged crosswise to form an X shape. The main frame of the square steel fence 2.1.2 can rotate within a 90-degree range.

[0040] like Figure 17 and 18As shown, the telescopic folding fence 2.1 also includes multiple fence locking bolt and nut sets 2.1.4. Each set includes bolts and nuts. Each fence foot plate 2.1.1 has two first limiting holes, which are positioned opposite each other on the two side walls of the fence foot plate 2.1.1. A positioning hole 2.1.17 is provided at the first end near the main frame of the square steel fence 2.1.2. When the main frame of the square steel fence 2.1.2 moves... When the bolt rotates downwards to abut against the patterned steel plate platform 2.2.3, the bolt shank passes through the two first limit holes in sequence and connects with the nut. The bolt shank is used to lock the square steel guardrail main frame 2.1.2 upwards. When the square steel guardrail main frame 2.1.2 rotates upwards to a vertical position, the bolt shank passes through one first limit hole, positioning hole 2.1.17, and another first limit hole in sequence and connects with the nut. The bolt shank locks the square steel guardrail main frame 2.1.2 in a locked position.

[0041] like Figure 11-17 As shown, the sunshade and rainproof awning includes multiple steel frames with telescopic guardrails 2.1.6, multiple sets of roof keel fixing bolts and nuts 2.1.7, multiple roof keel fixing brackets 2.1.8, multiple foldable roof keels 2.1.9, multiple foldable hooks 2.1.12, and multiple awnings 2.5. The steel frames with telescopic guardrails 2.1.6 are formed into hollow cuboids. The upper end, lower end, and the first part of the square steel main frame 2.2.1 of the steel frame with telescopic guardrails 2.1.6 are... Both sides are open. The steel frame 2.1.6 of the guardrail expansion channel can slide up and down inside the main frame 2.1.2 of the square steel guardrail. The first end of the foldable roof keel 2.1.9 extends into the upper end of the steel frame 2.1.6 of the guardrail expansion channel and is then connected to the hinge device 2.1.10 of the roof keel to the steel frame 2.1.6 of the guardrail expansion channel via the guardrail expansion channel. The width of the foldable roof keel 2.1.9 is smaller than the inner width of the steel frame 2.1.6 of the guardrail expansion channel. The foldable roof keel 2.1.9 is formed into a hollow cuboid shape. The top, bottom, and first side of the foldable roof keel 2.1.9 are all open. The first end of the roof keel fixing bracket 2.1.8 extends into the interior from the first side of the foldable roof keel 2.1.9 and is connected to the roof keel hinge device 2.1.11 via the fixing bracket, which is hinged to the foldable roof keel 2.1.9.

The canopy 2.5 is placed directly above the patterned steel plate platform 2.2.3.

[0042] The structures of the guardrail expansion groove steel frame connecting the canopy keel hinge device 2.1.10, the fixed bracket connecting the canopy keel hinge device 2.1.11, and the fence foot baffle connecting the fence main frame hinge device 2.1.13 are the same, and all use pin shafts.

[0043] like Figure 11 and 14 As shown in Figures 16, 17, and 18, the sunshade and rainproof canopy also includes multiple spring ball plungers 2.1.16. The spring ball plungers 2.1.16 are installed below the side wall of the steel frame 2.1.6 of the guardrail expansion groove. Correspondingly, spring ball plunger holes 2.1.15 are reserved above the side wall of the main frame 2.1.2 of the square steel guardrail, and spring ball plunger holes 2.1 are reserved below the side wall of the main frame 2.1.2 of the guardrail. 14. When the steel frame 2.1.6 of the guardrail expansion channel is fully retracted into the main frame 2.1.2 of the square steel guardrail, the spring ball plunger 2.1.16 engages with the pre-drilled spring ball plunger hole 2.1.14 at the bottom of the main frame; when the steel frame 2.1.6 of the guardrail expansion channel extends out of the main frame 2.1.2 of the square steel guardrail, the spring ball plunger 2.1.16 engages with the pre-drilled spring ball plunger hole 2.1.15 at the top of the main frame. Through the pre-drilled spring ball plunger hole 2.1.14 at the bottom of the main frame, the pre-drilled spring ball plunger hole 2.1.15 at the top of the main frame, and the spring ball plunger 2.1.16, the retraction and extension of the steel frame 2.1.6 of the guardrail expansion channel is achieved, thus demonstrating an overall expansion and contraction effect on the ceiling frame. like Figure 11 As shown, the length of the ceiling keel fixing bracket 2.1.8 is less than or equal to the first length, which is the length from the second end of the ceiling foldable keel 2.1.9 to the junction of the ceiling keel fixing bracket 2.1.8 and the ceiling foldable keel 2.1.9. The length of the ceiling foldable keel 2.1.9 is less than the second length, which is the length by which the guardrail expansion groove steel frame 2.1.6 extends beyond the square steel guardrail main frame 2.1.2 when the spring ball plunger 2.1.16 engages with the reserved spring ball plunger hole 2.1.15 on the upper part of the guardrail main frame.

[0044] like Figure 8 and 9As shown in Figures 10 and 21, the sliding form and platform hinge device 2.3 includes a sliding form connecting steel plate 1.1, a sliding form pin steel plate 1.2, a platform connecting bolt 2.3.1, a platform connecting nut 2.3.2, a platform fixing pin 2.3.3, a platform fixing steel plate 2.3.4, and a platform connecting steel plate 2.3.5. The sliding form connecting steel plate 1.1 and the sliding form pin steel plate 1.2 are installed side by side on the panel sliding form 1. The sliding form connecting steel plate 1.1 has a first connecting hole 1.3 and a second connecting hole 1.4 arranged side by side. The first connecting hole 1.3 is located near the end of the sliding form connecting steel plate 1.1. The sliding form pin steel plate 1.2 has a third connecting hole 1.5. The platform fixing steel plate 2.3.4 and the platform connecting steel plate 2.3.5 are installed side by side on the second end of the sliding form side angle steel frame 2.2.2. The platform connecting steel plate 2.3.5 has a fourth connecting hole 2.3.6 arranged side by side. Five connecting holes 2.3.7 are provided near the end of the platform connecting steel plate 2.3.5. The shank of the platform connecting bolt 2.3.1 passes through the first connecting hole 1.3 and the fourth connecting hole 2.3.6 in sequence and then engages with the platform connecting nut 2.3.2. In the working state, the foldable lightweight surface curing platform 2 flips downward under the action of gravity and is pressed against the lower end of the panel sliding mold 1 by the sliding mold side angle steel frame 2.2.2. In the non-working state, the foldable lightweight surface curing platform 2 flips upward. After flipping into place, the platform fixing steel plate 2.3.4 presses against the panel sliding mold 1. The second connecting hole 1.4, the fifth connecting hole 2.3.7, and the third connecting hole 1.5 are coaxially distributed. The platform fixing pin 2.3.3 passes through the second connecting hole 1.4, the fifth connecting hole 2.3.7, and the third connecting hole 1.5 in sequence to lock the platform frame 2.2.

[0045] The sliding formwork connecting steel plate 1.1 is made of 1cm thick steel plate. Two sliding formwork connecting steel plates 1.1 are welded to both ends of the sliding formwork 1. The main function of the sliding formwork connecting steel plate 1.1 is to be hinged through the holes inserted by the platform connecting bolts 2.3.1 and the holes on the platform connecting steel plate 2.3.5 on the platform, and to be fixed with the platform connecting nuts 2.3.2 to prevent it from falling off, so that the platform can rotate within the range.

[0046] like Figure 20As shown, a perforated steel pipe 2.4.2 is installed below the second end of the main square steel frame 2.2.1. The length of the perforated steel pipe 2.4.2 is the same as the length of the second end of the main square steel frame 2.2.1. The first end of the perforated steel pipe 2.4.2 is connected to a curing water switch ball valve 2.4.1, and the second end of the perforated steel pipe 2.4.2 is closed. Curing water flow holes of 4mm are drilled every 15cm on the perforated steel pipe 2.4.2. The curing water flows downwards through the perforations, forming a small but continuous and stable flow to cure the dam panel concrete below the slipform 1. The ball valve switch is connected to an external hose or PE pipe, which supplies curing water through the curing water pipeline system on the dam top and can be opened and closed.

[0047] Working principle: In its non-operational state, the structure of this application is as follows: Figure 7 As shown, when work is required, remove all platform fixing pins 2.3.3. With the assistance of hoisting equipment, the platform slowly rotates downwards under gravity until it is pressed against the lower end of the sliding mold panel 1 by the angle steel frame 2.2.2 on the sliding mold side. At this time, the structure is as follows. Figure 6 As shown; then remove the fence locking bolt and nut assembly 2.1.4, rotate the square steel fence main frame 2.1.2 upwards by 90 degrees, and then install the fence locking bolt and nut assembly 2.1.4. The bolt shank of the bolt should pass through one first limiting hole, positioning hole 2.1.17, and another first limiting hole in sequence before connecting with the nut. The bolt shank should lock and block the square steel fence main frame 2.1.2. At this point, the structure is as follows: Figure 5 As shown; then, press the spring ball plunger 2.1.16 inward at the pre-drilled spring ball plunger hole 2.1.14 at the lower part of the main frame of the guardrail, and pull up the steel frame 2.1.6 of the guardrail expansion groove until the spring ball plunger 2.1.16 pops out from the pre-drilled spring ball plunger hole 2.1.15 at the upper part of the main frame of the guardrail and locks in place. At this time, the structure is as follows. Figure 4 As shown; then, rotate the foldable roof keel 2.1.9 upwards 90 degrees from inside the guardrail expansion channel steel frame 2.1.6 and remove it. Remove the roof keel fixing bracket 2.1.8 downwards from inside the foldable roof keel 2.1.9. Connect the lower end of the roof keel fixing bracket 2.1.8 to the guardrail expansion channel steel frame 2.1.6 using the roof keel fixing bolt and nut assembly 2.1.7. The structure is now as shown. Figure 3 As shown; finally, hang the awning 2.5 on the multiple foldable hooks 2.1.12 below the multiple foldable roof joists 2.1.9. At this point, the structure is as follows. Figure 1 As shown, the operator can then work on the patterned steel plate platform 2.2.3; connect a hose or PE pipe to the ball valve switch, open the ball valve switch, and water can be sprayed through the perforated steel pipe 2.4.2 to cure the concrete of the dam panel below the slipform 1; the operation can be reversed when storing.

[0048] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
