Description

Technical Field

[0001] This invention relates to the field of grid beam construction technology, specifically to an integral formwork assembly for pouring grid beams for slope protection and its construction method. Background Technology

[0002] Grid reinforcement technology is a slope protection technique that uses grouted rubble masonry, cast-in-place reinforced concrete, or precast prestressed concrete for slope protection, and then secures it with anchor bolts or cables. After forming grid beams, the slope protection achieves both aesthetic appeal and safety. Grid beams are further divided into grouted rubble masonry grid beams and cast-in-place reinforced concrete grid beams.

[0003] Key points for the construction of cast-in-place reinforced concrete lattice structures: 1) Reinforced concrete lattices can be embedded in or overlaid on slopes; 2) The slope surface of the reinforced concrete lattice slope protection should be flat, compacted, and free of slippery surfaces, creeping bodies, and loose rock blocks; 3) The reinforcing bars used for casting the lattice should be stored in a dedicated warehouse to avoid contamination and corrosion. Ordinary Portland cement is generally used, and damp or expired cement should be avoided. Cast-in-place reinforced concrete lattice beams are generally constructed by first assembling prefabricated formwork into lattice units, and then pouring concrete between the lattice units. However, the commonly used formwork connections for cast-in-place reinforced concrete lattice beams are complex, have poor overall integrity, and are inconvenient to install and dismantle, increasing the construction period and difficulty.

[0004] Some existing technologies have made optimizations and improvements to this, such as patent CN209703525U, which provides a prefabricated lattice beam for slopes connected by wet joints. This includes prefabricated lattice beams and anchoring structures. The prefabricated lattice beam is a grid structure formed by splicing together several prefabricated lattice beam units, with wet joints connecting adjacent units. Each prefabricated lattice beam unit has several outwardly extending parallel connecting rings at its end. The connecting rings of adjacent units overlap at the wet joint, and a ring-shaped stirrup is vertically inserted and fixed at the intersection. Concrete is poured into the wet joint to connect the ends of adjacent units. Each unit includes a cross-shaped lattice beam with a central anchor hole, and the anchoring structure is fixed to the center of the cross-shaped lattice beam. However, this patent still does not solve the problem of inconvenient disassembly of the prefabricated lattice beam formwork, and large lifting equipment cannot be used in conjunction with the construction. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an integral formwork assembly for pouring slope protection grid beams and its construction method.

[0006] The technical solution of this invention is:

[0007] An integral formwork assembly for casting a slope protection grid beam includes formwork blocks, a rectangular grid unit formed by eight formwork blocks, and an overlapping assembly for connecting two grid units. Any two formwork blocks are rotatably connected by a movable shaft. A cross-shaped adapter is provided inside one of the formwork blocks on each side of the grid unit. A steel sling is rotatably connected inside the cross-shaped adapter. All four steel slings are rotatably connected to the bottom of a weighted hanging plate located at the center of the grid unit.

[0008] The overlapping components are provided in two sets and symmetrically arranged at the upper and lower ends of the same side of the lattice unit. The overlapping components include a snap-fit ​​block that snaps into the template block. The outer side of the snap-fit ​​block is provided with a telescopic rod. The end of the telescopic rod is provided with an L-shaped snap-fit ​​block. The inner side of the end of the L-shaped snap-fit ​​block is provided with several springs. The end of the springs is provided with a slider. The two sliders of the two sets of overlapping components are inclined on opposite sides, which are used to connect the lattice unit when it descends and limit the lattice unit. The top of the snap-fit ​​block is provided with a first fixing block, and the top of the L-shaped snap-fit ​​block is provided with a second fixing block. A threaded rod is provided between the first fixing block and the second fixing block. One end of the threaded rod is rotatably connected to the outer side of the first fixing block, and the other end of the threaded rod is rotatably connected to the threaded groove provided in the middle of the second fixing block, which is used to drive the second fixing block, the L-shaped snap-fit ​​block and the slider to move synchronously.

[0009] Furthermore, in each of the two template blocks on each side of the lattice unit, the cross-shaped adapter is installed on the inner rear wall of the template block that is relatively forward in a clockwise direction, and the steel sling is also rotatably connected to the bottom of the weighted hanging platform through a cross-shaped adapter.

[0010] Note: By strictly controlling the position of the cross joints on the template blocks, the lattice unit can remain stable during hoisting, and the template blocks on each side can be folded inward synchronously, ensuring the safety and efficiency of hoisting.

[0011] Furthermore, the cross adapter includes two clamping plates, with a connecting shaft fixedly connected between the clamping plates. Each of the two ends of the steel sling has a movable hole, one of which is connected to the connecting shaft of the cross adapter on the template block, and the other movable hole is connected to the connecting shaft of the cross adapter on the weighted lifting plate.

[0012] Note: The cross-shaped adapter allows the steel slings to rotate while ensuring lifting strength.

[0013] Furthermore, the weight-bearing platform is a regular square, with four cross-shaped adapters at the bottom of the platform located at the four corners of the platform, and the four cross-shaped adapters are arranged end to end. The top of the weight-bearing platform is equipped with a lifting ring.

[0014] Explanation: By strictly controlling the position of the four cross joints, the weighted lifting platform can remain stable during hoisting, and the weight of the platform can be used to gradually extend each template block when placing the lattice unit, ensuring the safety and efficiency of hoisting.

[0015] Furthermore, a snap-fit ​​groove is provided at the middle position of the bottom of the snap-fit ​​block, and the snap-fit ​​groove is slidably connected to the template block.

[0016] Note: The snap-fit ​​slot facilitates the placement and removal of the snap-fit ​​blocks.

[0017] Furthermore, there are two springs, with the ends of the springs extending into the grooves on the back of the slider, and the springs are fixedly connected to the bottom of the grooves. The inner sidewall of the L-shaped block end is provided with a limiting groove at the middle position of the two springs, and a limiting block is slidably connected inside the limiting groove.

[0018] Explanation: The spring and slider configuration allows the lattice unit to be placed relatively quickly and roughly positioned. As long as the two corners of the lattice unit correspond to the two sliders, the sliders can be pressed down and the springs squeezed, causing the two sets of springs to contract synchronously. This, in turn, causes the back of the sliders to touch the limit block, thus aligning the two lattice units horizontally.

[0019] Furthermore, a regular hexagonal nut is fixedly provided in the middle of the threaded rod.

[0020] Note: The nut design allows workers to easily use tools to turn the screw, thereby adjusting the spacing of the lattice units.

[0021] The present invention also provides a construction method for an integral formwork assembly for pouring slope protection grid beams based on any one of the above-mentioned methods, comprising the following steps:

[0022] S1. Lifting the lattice unit: Measure the distance and mark the lines on the slope where the lattice beam needs to be installed. Use a crane to lift the heavy-duty lifting platform of the lattice unit. As the heavy-duty lifting platform rises, it drives the four steel slings to rotate. As the heavy-duty lifting platform continues to move upward, the four steel slings gradually tighten and pull the corresponding template blocks through the cross joints located on the template blocks. This causes the middle of the four sides of the lattice unit to contract inward. At the same time, the entire lattice unit leaves the ground and is placed at the designated position on the slope. During placement, the heavy-duty lifting platform presses down on the four steel slings under its own weight, causing the steel slings to rotate downward and push each template block back to its original position. This causes the middle of the four sides of the lattice unit to extend outward. Finally, the lattice unit returns to a rectangle, completing the placement of the first lattice unit.

[0023] S2. Overlapping lattice unit: Hoist the second lattice unit using the same method as in step S1. Simultaneously, install two overlapping components on the upper and lower sides of the first lattice unit. When the lattice unit descends, its bottom contacts the inclined surfaces of the two sliders, causing the lattice unit to descend while pressing the two sliders to the sides, causing the springs to contract. When the lattice unit descends to the ground, the two sliders fix the two corners of the lattice unit under the action of the springs. Then, the weighted hoisting platform presses down on the four steel slings under its own weight and the external force, causing the steel slings to rotate downwards while pushing each template block back to its original position, so that the middle of the four sides of the lattice unit extends outwards. Finally, the lattice unit returns to a rectangle. The two sliders fix the upper and lower sides of the lattice unit under the action of the springs. Then, rotate the threaded rod so that it rotates in the threaded groove of the second fixing block, causing the second fixing block to move towards the side of the first lattice unit, thereby moving the entire second lattice unit towards the side of the first lattice unit until the distance between the two lattice units reaches the preset distance. Remove the two overlapping components and install them on the upper and lower sides of the second lattice unit.

[0024] S3. Pouring concrete: Place each row of lattice units in sequence according to the methods in steps S1 and S2. Nail positioning steel bars at the four corners of each lattice unit. Install triangular fixing angle irons at the upper part of the middle position of the two template blocks at each corner of each lattice unit. Install water-blocking angle irons above the template blocks above each lattice unit. Install spacing fixing angle irons between the template blocks of two adjacent lattice units. Then pour concrete between each lattice unit.

[0025] S4. Dismantling the lattice unit: After the concrete has solidified, use a crane to lift the weighted platform of the lattice unit, remove the lattice unit, and dismantle each lattice unit in turn.

[0026] Preferably, in step S2, when the overlapping component moves the entire second lattice unit toward the side of the first lattice unit, a limiting ruler is placed on the outer side of the template block corresponding to the second lattice unit on the side of the first lattice unit. The length of the limiting ruler is the preset distance between the two lattice units. When the side of the second lattice unit touches the limiting ruler, the distance between the two lattice units reaches the preset distance.

[0027] Note: The limit ruler helps staff confirm the spacing between two lattice units.

[0028] The beneficial effects of this invention are:

[0029] (1) The integral formwork assembly for pouring slope protection grid beams of the present invention integrates 8 formwork blocks into a whole as a grid unit, which facilitates the hoisting with large hoisting equipment during construction and avoids the drawbacks of traditional slope protection formwork, such as cumbersome disassembly and assembly, consumption of a lot of manpower, and inability to use large equipment for construction.

[0030] (2) The integral template assembly for pouring slope protection grid beams of the present invention enables the grid units to be roughly positioned according to their approximate location by setting the overlapping components. As long as the two corners of the grid unit correspond to the two sliders, the sliders can be pressed down and the springs squeezed, so that the two sets of springs contract synchronously and work together to make the back of the sliders touch the limit block, so that the two grid units can be horizontally aligned, which greatly improves the positioning efficiency of the grid units. The positioning is also accurate. The setting of the nut makes it convenient for workers to use tools to turn the screw, thereby realizing the adjustment of the spacing of the grid units. After placement, the overlapping components can be quickly disassembled and then quickly installed on the next grid unit to place the next set of grid units.

[0031] (3) The integral formwork assembly for pouring slope protection grid beams of the present invention strictly controls the position of the cross joints on the formwork blocks, so that the grid unit can remain stable during hoisting, and the formwork blocks on each side can be folded inward synchronously, ensuring the safety and efficiency of hoisting; the setting of the cross joints enables the rotation of the steel slings, while ensuring the hoisting strength; by strictly controlling the position of the four cross joints, the weighted lifting platform can remain stable during hoisting, and the weight of the weighted lifting platform can be used to gradually extend each formwork block when placing the grid unit, ensuring the safety and efficiency of hoisting.

[0032] (4) The construction method of the integral formwork assembly for pouring slope protection grid beam of the present invention provides a detailed description of the structure of the formwork assembly, and at the same time, the limit ruler facilitates the staff to confirm the spacing between two grid units.

Detailed Implementation

[0046] Example 1

[0047] like Figure 1 , 2As shown in Figures 7, 9, and 10, an integral formwork assembly for pouring a slope protection grid beam includes formwork blocks 1, a rectangular grid unit 2 formed by eight formwork blocks 1, and an overlapping assembly 3 for connecting two grid units 2. Any two formwork blocks 1 are rotatably connected via a movable shaft 11. A cross-shaped adapter 4 is provided inside one of the formwork blocks 1 on each side of the grid unit 2. Steel slings 5 ​​are rotatably connected inside the cross-shaped adapter 4. All four steel slings 5 ​​are connected to a heavy-duty sling located at the center of the grid unit 2. The bottom of the plate 6 is rotatably connected. In the two template blocks 1 on each side of the lattice unit 2, a cross-shaped adapter 4 is installed on the inner wall of the rear end of the template block 1 that is relatively forward in the clockwise direction. The steel sling 5 is also rotatably connected to the bottom of the heavy-duty hanging plate 6 through a cross-shaped adapter 4. The heavy-duty hanging plate 6 is set in a regular quadrilateral shape. The four cross-shaped adapters 4 at the bottom of the heavy-duty hanging plate 6 are located at the four corners of the heavy-duty hanging plate 6, and the four cross-shaped adapters 4 are set end to end. The top of the heavy-duty hanging plate 6 is provided with a lifting ring 61.

[0048] like Figures 7-10 As shown, the cross adapter 4 includes two clamping plates 41, and a connecting shaft 42 is fixedly connected between the clamping plates 41. Each of the two ends of the steel sling 5 is provided with a movable hole 51. One movable hole 51 is connected to the connecting shaft 42 of the cross adapter 4 on the template block 1, and the other movable hole 51 is connected to the connecting shaft 42 of the cross adapter 4 on the weighted hanging plate 6.

[0049] like Figures 3-5As shown, the overlapping components 3 are provided in two sets and symmetrically arranged at the upper and lower ends of the same side of the lattice unit 2. The overlapping components 3 include a snap-fit ​​block 31 that snaps into the template block 1. A snap-fit ​​groove 311 is provided at the middle position of the bottom of the snap-fit ​​block 31, and the snap-fit ​​groove 311 is slidably connected to the template block 1. A telescopic rod 32 is provided on the outer side of the snap-fit ​​block 31, and an L-shaped snap-fit ​​block 33 is provided at the end of the telescopic rod 32. Two springs 34 are provided on the inner side of the end of the L-shaped snap-fit ​​block 33. A slider 35 is provided at the end of the spring 34. The end of the spring 34 extends into the groove hole 351 provided on the back of the slider 35, and the spring 34 is fixedly connected to the bottom of the groove hole 351. A limiting groove 331 is provided on the inner side wall of the end of the L-shaped snap-fit ​​block 33 at the middle position of the two springs 34. The limiting groove 331 is equipped with a limiting block 39 that slides up and down inside. The two sliders 35 of the two sets of overlapping components 3 have an inclined surface on one side, which is used to dock the lattice unit 2 when it descends and limit the lattice unit 2. The top of the snap block 31 is equipped with a first fixing block 36, and the top of the L-shaped snap block 33 is equipped with a second fixing block 37. A threaded rod 38 is provided between the first fixing block 36 and the second fixing block 37. One end of the threaded rod 38 is rotatably connected to the outer side of the first fixing block 36, and the other end of the threaded rod 38 is rotatably connected to the threaded groove 371 provided in the middle of the second fixing block 37, which is used to drive the second fixing block 37, the L-shaped snap block 33 and the slider 35 to move synchronously. A regular hexagonal nut 381 is fixed in the middle of the threaded rod 38.

[0050] Example 2

[0051] The difference between this embodiment and Embodiment 1 is that:

[0052] Four springs 34 are provided on the inner side of the end of the L-shaped block 33, and the limiting groove 331 is located in the middle of the two springs 34.

[0053] Example 3

[0054] This embodiment is a construction method for an integral formwork assembly for pouring slope protection grid beams, as described in Embodiment 1, and includes the following steps:

[0055] S1. Lifting of lattice unit 2: Measure the distance and mark the lines on the slope where the lattice beams need to be installed. Use a crane to lift the weighted lifting platform 6 of lattice unit 2. As the weighted lifting platform 6 rises, it drives the four steel slings 5 ​​to rotate. As the weighted lifting platform 6 continues to move upward, the four steel slings 5 ​​gradually tighten and pull the corresponding template block 1 through the cross-shaped adapter 4 located on the template block 1, causing the middle of the four sides of the lattice unit 2 to contract inward. At the same time, the entire lattice unit 2 leaves the ground. Figure 6As shown in the diagram, the lattice unit 2 is placed at the designated location on the slope. During placement, the weighted lifting platform 6 presses down on the four steel slings 5 ​​under its own weight, causing the steel slings 5 ​​to rotate downwards while pushing each template block 1 back to its original position. This causes the middle of the four sides of the lattice unit 2 to extend outwards, ultimately restoring the lattice unit 2 to a rectangular shape, completing the placement of the first lattice unit 2. Figure 1 The state shown;

[0056] S2, Overlapping lattice unit 2: Hoist the second lattice unit 2 using the same method as in step S1, while simultaneously installing two overlapping components 3 on the upper and lower sides of the first lattice unit 2, such as... Figure 2 In the state shown, when the lattice unit 2 descends, its bottom contacts the inclined surfaces of the two sliders 35, as indicated. Figure 11 As shown in the diagram, while the lattice unit 2 descends, it presses the two sliders 35 to both sides, causing the spring 34 to contract. When the lattice unit 2 descends to the ground, the two sliders 35 fix the two corners of the lattice unit 2 under the action of the spring 34. Then, the weighted hanging plate 6 presses down the four steel slings 5 ​​under its own weight and the external force, so that the steel slings 5 ​​push each template block 1 back to its original position while rotating downwards, so that the middle of the four sides of the lattice unit 2 extends outwards. Finally, the lattice unit 2 returns to a rectangle. The two sliders 35 fix the upper and lower sides of the lattice unit 2 under the action of the spring 34. Then, the threaded rod 38 is rotated so that it rotates in the threaded groove 371 of the second fixing block 37, causing the second fixing block 37 to move towards the side of the first lattice unit 2, thereby causing the entire second lattice unit 2 to move towards the side of the first lattice unit 2, until the distance between the two lattice units 2 reaches the preset distance of 30cm. The two overlapping components 3 are removed and installed on the upper and lower sides of the second lattice unit 2.

[0057] like Figure 12 In the state shown, when the overlapping component 3 moves the entire second grid unit 2 toward the side of the first grid unit 2, a limiting ruler 7 is placed on the outer side of the template block 1 on the side of the first grid unit 2 corresponding to the second grid unit 2. The length of the limiting ruler 7 is the preset distance between the two grid units 2, which is 30cm. When the side of the second grid unit 2 touches the limiting ruler 7, the distance between the two grid units 2 reaches the preset distance of 30cm.

[0058] S3. Pouring concrete: Place each row of lattice unit 2 in sequence according to the methods in steps S1 and S2. Nail positioning steel bars at the four corners of each lattice unit 2. Install triangular fixing angle irons at the upper part of the middle position of the two template blocks 1 at each corner of each lattice unit 2. Install water-blocking angle irons above the template block 1 above each lattice unit 2. Install spacing fixing angle irons between the template blocks 1 of two adjacent lattice units 2. Then pour concrete between each lattice unit 2.

[0059] S4. Demolition of lattice unit 2: After the concrete has solidified, use a crane to lift the weighted lifting platform 6 of lattice unit 2, remove lattice unit 2, and demolish each lattice unit 2 in sequence.

[0060] Example 4

[0061] The difference between this embodiment and Embodiment 3 is that:

[0062] The preset spacing between the two lattice units 2 is 10cm, and the length of the limiting ruler 7 is also 10cm.

[0063] Example 5

[0064] The difference between this embodiment and Embodiment 3 is that:

[0065] The preset spacing between the two lattice units 2 is 50cm, and the length of the limiting ruler 7 is also 50cm.

[0066] Experimental Example

[0067] The following describes the actual operation of a construction method for an integral formwork assembly for pouring slope protection grid beams according to the present invention. After multiple constructions on different slopes, the construction efficiency results were statistically analyzed and compared with other construction methods.

[0068] Comparative Example 1 did not use the lattice unit 2 and overlapping component 3 of the present invention, but simply used template block 1 for on-site assembly;

[0069] Comparative Example 2 did not use the overlapping component 3 of the present invention, and manual distance measurement was used to adjust the spacing of the lattice unit 2.

[0070] Ultimately, we found that under the same lattice beam quality, the construction method in Example 3 had a significantly shorter working time than the other two methods. Compared with Comparative Example 1, Example 3 improved the installation efficiency by 20-30% and the demolition efficiency by 15-20%. Compared with Comparative Example 2, Example 3 improved the installation efficiency by 5-10%. It can be seen that the template component of the present invention, combined with the construction method of the present invention, can achieve good results and greatly shorten the construction period.
