Description

Technical Field

[0001] This invention relates to the field of lock construction technology, and in particular to a detachable steel reinforcement frame for lock chambers and its construction method. Background Technology

[0002] Currently, the sidewalls of ship locks often adopt a trapezoidal cavity design. The formwork for this structure is mostly constructed using traditional full-span scaffolding. However, the installation of this traditional full-span scaffolding often consumes a large amount of manpower and resources, increasing construction costs. Furthermore, due to the limited internal space of the hollow wall structure, the installation and dismantling of the scaffolding is extremely difficult, resulting in low scaffolding construction efficiency and extending the overall project construction period.

[0003] Chinese patent document CN 112900442 A describes a method for rapid construction of high concrete formwork for lock piers. However, this method has high requirements for the height of the formwork, requires full-span scaffolding, and necessitates a matching trolley during the process. However, the height of a lock chamber is generally around 20 meters, resulting in high trolley usage costs and relatively low construction efficiency. Chinese patent document CN214738076 U describes a construction device for pouring concrete for lock chamber walls, but it still has the above-mentioned problems and its use has defects, requiring improvement.

Detailed Implementation

[0018] like Figure 1-5In this paper, a detachable steel reinforcement frame for a lock chamber includes support frames 1 on both sides of a connecting rod 2. The two support frames 1 are connected by the connecting rod 2. Each support frame 1 includes two parallel vertical supports 101. One vertical support 101 has multiple toothed plates 4, and the other vertical support 101 has multiple sliding tubes 3 slidably connected to it. The ends of the multiple sliding tubes 3 are connected by diagonal braces 5. The support frames 1 and the lowermost sliding tube 3 are detachably mounted on a limiting component 8. The diagonal braces 5 have multiple toothed plates 4. The support frames 1, sliding tubes 3, toothed plates 4, and diagonal braces 5 are connected to form an operating space 7. In traditional construction, when pouring concrete as a whole, a full-span scaffold is required for tying the reinforcing steel and supporting the formwork. This limits the construction pace, and the safety risks increase with the height of the scaffold. For lock chambers with a single section length of 15-20 meters, the amount of scaffolding used is very large, and the workload of installation and dismantling is correspondingly high. At the same time, appropriate trolleys are required for coordination, resulting in high operating costs. This solution uses layered casting, which requires only simple minor adjustments to ensure the ease of splicing and binding of the reinforcing bars before each layer of the standard segment is poured. At the same time, the lower layer 6, which has been poured, provides a stable foothold and support point during construction, ensuring safe and efficient use. The height of the skeleton can be adjusted layer by layer along the height to achieve rapid construction of different levels.

[0019] like Figure 6-8 In the preferred embodiment, the outer side of the vertical brace 101 is provided with multiple first connecting seats 107, each with a fourth through hole 108. The outer side of the diagonal brace 5 is provided with multiple second connecting seats 503, each with a seventh through hole 506. The toothed plate 4 is provided with multiple through slots 401 and fifth through holes 402. Screws 15 are respectively inserted into the fourth through hole 108 and the fifth through hole 402, and the seventh through hole 506 and the fifth through hole 402. The reinforcing bars are fitted into the through slots 401. This structure allows the vertical brace 101 and the diagonal brace 5 to cooperate with each other, thereby facilitating the stable installation of the toothed plate 4. The toothed plate 4 is firmly connected and easy to install and disassemble. At the same time, as a load-bearing component of the frame, the toothed plate 4 contributes to the overall structural stability of the frame, facilitating high precision in reinforcing bar splicing projects and resulting in good performance.

[0020] like Figure 9-12In the preferred embodiment, the two vertical supports 101 are connected by multiple horizontal supports 102. The sliding tube 3 passes through the horizontal supports 102. A fixing block 10 is also provided between the vertical supports 101 and the horizontal supports 102. The fixing block 10 has a tenth through hole 1001 in the middle. The connecting rod 2 passes through the tenth through hole 1001. The two sides of the connecting rod 2 are connected to the fixing block 10 by multiple nuts 13. The cast-in-place layer 6 is provided with a pre-embedded sleeve 16 and a pad 17. The pad 17 is supported on the bottom of the sliding tube 3. The support frame 1 is connected to the pre-embedded sleeve 16 by fixing nails 11. The fixing nails 11 pass through the support frame 1. This structure allows the pad 17 to support the slide pipe 3 from the bottom, ensuring that the support frame 1 and the slide pipe 3 are in stable and full contact with the poured layer 6, resulting in stable stress and thus ensuring the accuracy of the rebar splicing and high construction safety. The embedded sleeve 16 ensures that the support frame 1 is firmly locked, providing operators with good load-bearing capacity and anti-overturning ability during construction.

[0021] In the preferred embodiment, the cross brace 102 has first oblong holes 103 extending through both sides. An adjustment component 9 is detachably installed on the first oblong hole 103 near the slide tube 3. The adjustment component 9 includes a drive gear 902, and the slide tube 3 has multiple toothed grooves 302. The drive gear 902 and the toothed grooves 302 are meshed together. This structure allows the operator to quickly adjust the position of the slide tube 3, while also providing convenient locking and avoiding the problem of parts loss when using other connection methods.

[0022] like Figure 16-17 In the preferred embodiment, the drive gear 902 is provided with a base 901 on both sides, the base 901 is connected to the cross brace 102, the shaft 903 passes through the base 901 and the drive gear 902, the shaft 903 is also provided with a limiting gear 904 and a turntable 905 on one side, the limiting gear 904 is detachably fitted with a fixing sleeve 907, the fixing sleeve 907 is connected to a round rod 908 through a baffle 906, the round rod 908 is threadedly connected to a top sleeve 909 on both sides, the round rod 908 is provided with an annular groove 910 in the middle, the upper part of the tenth through hole 1001 is provided with a third threaded hole 1002, the fixing nail 11 is located in the third threaded hole 1002, the diameter of the fixing nail 11 matches the width of the annular groove 910, the vertical brace 101 is also provided with a first through hole 104, the fixing nail 11 is threadedly connected to the first through hole 104, and the end of the fixing nail 11 abuts against the side wall of the slide tube 3. This structure allows the position of the slide tube 3 relative to the support frame 1 to be adjusted by rotating the turntable 905 of the adjustment component 9 in both directions. After adjustment, the fixed sleeve 907 on one side of the baffle 906 is used for locking, which is convenient and has a good fixing effect. The fixing nail 11 further ensures that the contact area between the fixed sleeve 907 and the limiting gear 904 is large, making it flexible to use.

[0023] In a preferred embodiment, the end of the sliding tube 3 is provided with a hinge joint 301, and one side of the diagonal brace 5 is provided with a first mounting seat 501. Multiple second mounting seats 502 are provided on the upper side of the first mounting seat 501. A sixth through hole 504 and a second oblong hole 505 are respectively provided through the first mounting seat 501 and the second mounting seats 502. The hinge joint 301 is connected to the first mounting seat 501 and the second mounting seats 502 respectively via a pin 12. This structure ensures the stability of the diagonal brace 5 connection and allows for adjustment of the angle between the diagonal brace 5 and the sliding tube 3 as needed, adapting to changes in the angle of the gate chamber's sidewall, meeting stress requirements, and ensuring convenient construction.

[0024] like Figure 13-15 In a preferred embodiment, a limiting component 8 is detachably provided between the slide tube 3 and the diagonal brace 5. The limiting component 8 includes two adapter seats 801, which are respectively installed on the slide tube 3 and the diagonal brace 5. One adapter seat 801 is hinged to a first rotating plate 802 via a pin 12, and the other adapter seat 801 is hinged to a second rotating plate 803 via a pin 12. The first rotating plate 802 has an eighth through hole 804 and a first threaded rod 806 on both sides, and the second rotating plate 803 has a ninth through hole 805 and a second threaded hole 810 on both sides. The pin 12 passes through the eighth through hole 804 and the ninth through hole 805, respectively. The first threaded rod 806 is connected to the second rotating plate 803 via a locking sleeve 807. The locking sleeve 807 has a first threaded hole 808 and a second threaded rod 809 on both sides, and the first threaded rod 806 and the first threaded hole 808 are threadedly connected, as are the second threaded rod 809 and the second threaded hole 810. This structure allows for further locking of the slide tube 3 and the diagonal brace 5. The limiting component 8 connects the slide tube 3 and the diagonal brace 5 to form a triangular force model. The overall locking effect is good and the adjustment is convenient. By changing the position of the locking sleeve 807, the connection state between the first rotating plate 802 and the second rotating plate 803 can be changed.

[0025] In a preferred embodiment, the outer side of the support frame 1 is detachably provided with a support frame 1 along both the horizontal and vertical directions. The vertical support 101 has multiple second through holes 105 and third through holes 106. The two horizontally connected support frames 1 are connected by screws 15, which pass through the second through holes 105. The two vertically connected support frames 1 are connected by a telescopic assembly 14. The telescopic assembly 14 includes two opposing base plates 1401, which are connected to the vertical support 101 by screws 15, which pass through the third through holes 106. A threaded sleeve 1402 is provided in the middle of the base plate 1401. The two opposing threaded sleeves 1402 have opposite thread directions and are connected by a bidirectional threaded rod 1403. The bidirectional threaded rod 1403 has a hexagonal head 1404 in the middle. This structure allows the support frame 1 to be extended in both length and width directions as needed, ensuring strong load-bearing capacity and sufficient force distribution, thereby guaranteeing overall construction safety and efficiency, convenient operation, and easy installation and dismantling.

[0026] In a preferred embodiment, a construction method for a detachable steel reinforcement frame for a lock chamber includes the following steps: S1. Process the support frame 1, connecting rod 2, sliding tube 3, toothed plate 4 and diagonal brace 5 according to the cross-sectional dimensions of the lock chamber sidewall. Since the design dimensions of the lock chamber sidewalls of different locks are different, appropriate support frames 1 and sliding tubes 3 can be set and their dimensions can be flexibly changed through matching. S2. Assemble the components from S1 into a whole, and then debug it; S3. Hoist the entire device from S2 to the top of the side wall of the gate chamber, unfold and lock it in place after initial adjustment. The built-in design avoids interference with existing steel bars during hoisting, thus preventing operational inconvenience. S4. Position and tie the vertical and longitudinal reinforcing bars on the support frame 1 and the diagonal brace 5 respectively; S5. Tie the tied steel bars to ensure rigidity; S6. Remove the toothed plate 4 on the support frame 1 and the diagonal brace 5 in sequence, then retract the slide tube 3 into the support frame 1 and fix it. S7. After fixing the toothed plate 4 to the support frame 1, retract the device to its minimum state and then lift it out of the rebar area. S8. Provide formwork support on the upper part of the already poured layer 6, complete the pouring and curing; S9. Based on the height variation of the poured layer 6, the entire device extends and ties the reinforcing bars on top of the poured layer 6. S10. Repeat S3 to S9 until the overall construction of the gate chamber sidewall is completed.

[0027] In the preferred embodiment, in S3, the support frame 1 is first positioned and locked according to the design drawings and the width of the top surface of the poured layer 6. Then, the position of the slide tube 3 is adjusted and extended using the adjustment component 9. Once the slide tube 3 meets the set dimensions, it is fixed. At the same time, when each layer is poured, the pre-embedded sleeve 16 and pad 17 are embedded at the corresponding position on the top. In S7, the slide tube 3 is also adjusted and retracted using the adjustment component 9.
