Description

Technical Field

[0001] This utility model relates to the field of template technology, specifically to a template for pouring foundation pits in hydropower construction. Background Technology

[0002] In the field of hydropower engineering construction, the formwork for pouring concrete in foundation pits is a key support device to ensure the formation of concrete structures. Traditional foundation pit formwork mostly adopts a support system composed of rigid plates and supporting rods. Its design is mainly for the pouring needs of conventional square, rectangular and other vertical structures. However, it is often necessary to pour concrete structures with non-vertical geometric features such as inclined right-angled sides in the foundation pit (such as the transition section of the diversion pier, the slope of the stilling basin, etc.).

[0003] In existing technologies, construction workers typically adjust the angle of the formwork by cutting its edges on-site or splicing multiple panels to meet the support requirements of irregular structures. At inclined right-angled edges, workers need to bevel or wedge-cut the formwork to match the angle of inclination. On-site cutting is inefficient, and its accuracy depends on manual experience, which can easily lead to grout leakage at corner intersections. Furthermore, the reuse rate of cut formwork is low, resulting in significant material waste and increased costs. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a formwork for pouring foundation pits in hydropower construction, which solves the issues of uncontrollable precision and difficulty in reusing the corner intersections of sloped surfaces when cutting formwork on-site.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a formwork for pouring foundation pits in hydropower construction, comprising a support plate and a support member. The support plate includes a main fixing plate, a side fixing plate, an outer plate, an inner rotating plate, and an inner sliding plate. The adjacent connections of the main fixing plate, the side fixing plate, the inner rotating plate, and the inner sliding plate are provided with protrusions and grooves. The inner rotating plate is slidably installed on one side of the outer plate, and the inner sliding plate is slidably installed on the other side of the outer plate. One end of the support member is slidably inserted into the plate.

[0006] The outer jacket includes a first plate, a groove, a positioning hole, and a slot. The first plate is hollow. A groove is formed on the outer surface of the first plate away from the poured concrete, and the positioning hole is formed on the upper and lower sides of the groove. A slot is formed on the bottom inner side of the first plate. The bottom of the inner rotating plate is engaged with the slot. The rotating end of the inner rotating plate is slidably connected to the groove. The sliding end of the inner sliding plate is slidably connected to the groove.

[0007] The main fixing plate has a straight cross-section, with a protrusion, a groove, and a limiting groove at each end. The side fixing plate has an L-shaped cross-section, with a protrusion, a groove, and a limiting groove at each end. The inner rotating plate has a groove and a limiting groove on the side away from the outer plate, and the inner sliding plate has a protrusion and a limiting groove on the side away from the outer plate.

[0008] The inner rotating plate includes a second plate, a first adjusting rod, and a locking tooth. The second plate is slidably installed inside the first plate. A cylinder is fixedly installed on the surface of the second plate. The first adjusting rod is slidably fitted onto the surface of the cylinder. A first protruding post is fixedly installed on the free end of the first adjusting rod. A bolt is provided on the free end of the first adjusting rod. The bottom of the second plate has an arc surface, and a locking tooth is fixedly installed on the arc surface.

[0009] The inner sliding plate includes a third plate and a second adjusting rod. The third plate is slidably installed inside the first plate. A square post is fixedly installed on the surface of the third plate. The second adjusting rod is fixedly sleeved on the surface of the square post. A second protruding post is fixedly installed on the free end of the second adjusting rod. A bolt is provided on the free end of the second adjusting rod.

[0010] The support component includes a sliding sleeve, a connecting plate, a rotating seat, a push rod, and a push plate. A connecting plate is fixedly installed on one side of the sliding sleeve, a slider is slidably installed inside the sliding sleeve, a rotating seat is fixedly installed on the surface of the slider, and a push rod is fixedly installed on the rotating end of the rotating seat. The push rod and the push plate are connected by a thread.

[0011] The number of the support components is multiple sets, and each set of connecting plates is slidably installed in the adjacent limiting grooves of the main fixing plate, side fixing plate, inner rotating plate and inner sliding plate. The push rod consists of a crossbar and a screw. One end of the crossbar is fixedly connected to one side of the rotating end of the rotating seat, and the other end of the crossbar is rotatably connected to one end of the screw. The other end of the screw is threadedly connected to the push plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention allows the inner rotating plate to slide inside the first plate by pulling it. The horizontal movement of the inner rotating plate is converted into a flipping motion by the meshing connection between the slot and the bottom of the inner rotating plate. This causes the side fixing plate connected to the inner rotating plate to adjust its angle. The side fixing plate provides sufficient support for the inclined right-angled edge of the poured concrete, preventing grout leakage. Furthermore, the rotation of the inner rotating plate inside the first plate allows for adjustment of the tilt angle of the side fixing plate. Compared to cutting templates, this design allows for repeated use, increasing material reuse and reducing waste. By pushing the inner sliding plate to slide inside the first plate, the overall dimensions and width of the outer plate, inner rotating plate, and inner sliding plate are changed. After the tilt angle of the side fixing plate is adjusted by the inner rotating plate, the side fixing plate can be quickly moved to the designated position. Attached Figure Description

Protrusions and grooves are provided at adjacent connections of the main fixing plate 1, the side fixing plate 2, the inner rotating plate 4, and the inner sliding plate 5. The inner rotating plate 4 is slidably installed on one side of the outer plate 3, and the inner sliding plate 5 is slidably installed on the other side of the outer plate 3. One end of the support member 6 is slidably inserted into the plate. The outer plate 3 includes a first plate body 301. The slide 302, positioning hole 303 and slot 304 are provided. The first plate 301 is hollow. The slide 302 is provided on the outer surface of the first plate 301 away from the concrete being poured. The positioning hole 303 is provided on the upper and lower sides of the slide 302. The slot 304 is provided on the bottom inner side of the first plate 301. The bottom of the inner rotating plate 4 is engaged with the slot 304. The rotating end of the inner rotating plate 4 is slidably connected to the slide 302. The sliding end of the inner sliding plate 5 is slidably connected to the slide 302.

[0026] Specifically, the support plate is used to support the area to be poured to ensure the stable formation of concrete. The main fixing plate 1, the side fixing plate 2, the inner rotating plate 4 and the inner sliding plate 5 are connected and fixed by the support member 6. The main fixing plate 1 serves as the main body of the plate when it is supported, the side fixing plate 2 serves as the four corners when it is supported, and the outer plate 3, the inner rotating plate 4 and the inner sliding plate 5 serve as rotating members connected to the main fixing plate 1 when the side fixing plate 2 needs to be tilted.

[0027] The main fixing plate 1 has a straight cross-section, with a protrusion, a groove, and a limiting groove at both ends. The side fixing plate 2 has an L-shaped cross-section, with a protrusion, a groove, and a limiting groove at both ends. The inner rotating plate 4 has a groove and a limiting groove on the side away from the outer plate 3. The inner sliding plate 5 has a protrusion and a limiting groove on the side away from the outer plate 3. The protrusion and the groove are arranged correspondingly, and the limiting groove and the support member 6 are arranged correspondingly.

[0028] Specifically, the connection between the protrusion and the groove facilitates the quick interconnection of the main fixing plate 1, the side fixing plate 2, the inner rotating plate 4, and the inner sliding plate 5. The limiting groove enables the support member 6 to limit and fix the connection of the main fixing plate 1, the side fixing plate 2, the inner rotating plate 4, and the inner sliding plate 5.

[0029] The inner rotating plate 4 includes a second plate 401, a first adjusting rod 402, and a locking tooth 403. The second plate 401 is slidably installed inside the first plate 301. A cylinder is fixedly installed on the surface of the second plate 401. The first adjusting rod 402 is slidably fitted onto the surface of the cylinder. A first protrusion is fixedly installed on the free end of the first adjusting rod 402. The first protrusion is slidably inserted into the interior of the sliding groove 302. A bolt is provided on the free end of the first adjusting rod 402. The bolt passes through the first adjusting rod 402 to the interior of the positioning hole 303. The bottom of the second plate 401 is provided with an arc surface, and a locking tooth 403 is fixedly installed on the arc surface. The locking tooth 403 is engaged with the locking groove 304.

[0030] Specifically, the second plate 401 is rotated stably in the slot 304 by engaging the locking teeth 403 at the bottom of the second plate 401 with the slot 304. By pulling the first protrusion of the first adjusting rod 402, it slides inside the slide groove 302, thereby driving the second plate 401, which is rotatably connected to the first adjusting rod 402, to move inside the first plate 301. The tilt angle of the side fixing plate 2 connected to the second plate 401 is quickly adjusted. By turning the bolt at the first adjusting rod 402 into the positioning hole 303, the first adjusting rod 402 and the first plate 301 are connected and fixed.

[0031] The inner slide plate 5 includes a third plate body 501 and a second adjusting rod 502. The third plate body 501 is slidably installed inside the first plate body 301. A square post is fixedly installed on the surface of the third plate body 501. The second adjusting rod 502 is fixedly sleeved on the surface of the square post. A second protruding post is fixedly installed on the free end of the second adjusting rod 502. The second protruding post is slidably inserted into the interior of the slide groove 302. A bolt is provided on the free end of the second adjusting rod 502. The bolt passes through the second adjusting rod 502 to the interior of the positioning hole 303.

[0032] Specifically, the overall width of the outer jacket plate 3, inner rotating plate 4 and inner sliding plate 5 is adjusted by sliding the third plate 501 inside the first plate 301. The second protrusion of the second adjusting rod 502 is pulled to slide inside the slide groove 302, thereby driving the sliding of the third plate 501. The second adjusting rod 502 is connected and fixed to the first plate 301 by tightening the bolt at the second adjusting rod 502 into the positioning hole 303.

[0033] The support component 6 includes a sliding sleeve 601, a connecting plate 602, a rotating seat 603, a push rod 604, and a push plate 605. The connecting plate 602 is fixedly installed on one side of the sliding sleeve 601. A slider is slidably installed inside the sliding sleeve 601. A bolt fastener is provided at the slider. The bolt fastener passes through the surface of the sliding sleeve 601 and the slider. The rotating seat 603 is fixedly installed on the surface of the slider. The push rod 604 is fixedly installed at the rotating end of the rotating seat 603. The push rod 604 is threadedly connected to the push plate 605.

[0034] Specifically, the slider drives the rotating seat 603 to slide inside the sliding sleeve 601, thereby facilitating the change of the angle of the push rod 604 and the push plate 605, adjusting the push plate 605 to a stable support position, and by turning the push rod 604 to make it rotate on the push plate 605, a reverse force is applied to the sliding sleeve 601, the connecting plate 602 and the rotating seat 603 at the other end, pressing the support plate.

[0035] The number of support members 6 is multiple sets, and each set of connecting plates 602 is slidably installed in the adjacent limiting grooves of the main fixing plate 1, the side fixing plate 2, the inner rotating plate 4 and the inner sliding plate 5. The push rod 604 is composed of a crossbar and a screw. One end of the crossbar is fixedly connected to the rotating end of the rotating seat 603, and the other end of the crossbar is rotatably connected to one end of the screw. The other end of the screw is threadedly connected to the push plate 605.

[0036] Specifically, the connecting plate 602 is inserted into the adjacent limiting grooves of the main fixing plate 1, the side fixing plate 2, the inner rotating plate 4 and the inner sliding plate 5 to connect and fix them respectively. The screw is turned to make it rotate at the push plate 605, and the push rod 604 is pushed.

[0037] In summary: When using this utility model, during the pouring of foundation pit concrete, the workers align the adjacent main fixing plate 1, side fixing plate 2, inner rotating plate 4, and inner sliding plate 5 in pairs, so that the protrusions and grooves interlock. The connecting plate 602 is then slidably inserted into the limiting groove to connect and fix the adjacent main fixing plate 1, side fixing plate 2, inner rotating plate 4, and inner sliding plate 5. If the pouring concrete requires a right-angled side, the first protrusion of the first adjusting rod 402 can be pulled to slide inside the sliding groove 302. The first adjusting rod 402 pulls the second plate 401 to move inside the first plate 301. Relying on the engagement of the locking teeth 403 and the locking groove 304, the lateral pulling force causes the second plate 401 to rotate inside the first plate 301, adjusting the tilt angle of the side fixing plate 2 connected to the second plate 401. After reaching the desired angle, the first adjusting rod is turned. Bolt 402 into positioning hole 303 to limit and fix the first adjusting rod 402. If there is a gap between the horizontal position of the side fixing plate 2 and the designated position, the second protrusion of the second adjusting rod 502 can be pulled to slide inside the slide groove 302, driving the third plate 501 to move inside the first plate 301. Adjust the overall width of the outer plate 3, inner rotating plate 4 and inner sliding plate 5. Tighten the bolt at the second adjusting rod 502 to limit and fix it. Press the support plate as a whole to insert it into the soil, submerging the gap between the bottom and the ground when the second plate 401 flips and drives the side fixing plate 2 to rise. Adjust the support plate to the designated position. Insert or attach the push plate 605 into the foundation pit. Tighten the screw of the push rod 604 to rotate it at the push plate 605, pushing the support plate to provide support force. The installation of the template is completed. After the pouring is completed, the template can be recycled and reused.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
