Description

Technical Field

[0001] The utility model relates to the technical field of template support, in particular to a drainage ditch stabilizing inner support device. Background Art

[0002] Formwork support plays a crucial role in the construction of infrastructure such as drainage ditches. As the mold for concrete pouring, the stability and strength of the formwork are directly related to the drainage ditch's molding quality and construction safety. However, in traditional formwork support systems, the formwork often relies on simple wooden wedges or metal brackets. These support methods lack sufficient stability in complex terrain or unique engineering conditions. Especially during the concrete pouring process, the formwork is prone to displacement or deformation due to the concrete's deadweight and fluidity, thus affecting the final quality and appearance of the drainage ditch.

[0003] At the same time, traditional support devices are usually fixed and cannot be flexibly adjusted to accommodate drainage ditches of different widths and shapes. This results in construction workers having to frequently replace different support devices, increasing construction time and costs. In addition, the process of adjusting the support position on site is cumbersome and time-consuming, affecting construction efficiency. Furthermore, the operation of traditional support devices usually requires a lot of manual intervention, including manual adjustment of support positions, tightening screws, etc. This complex operation not only increases labor intensity, but may also lead to misoperation, which in turn affects construction safety and quality. In addition, during the concrete pouring process, the formwork needs to withstand continuous pressure to maintain its shape. Traditional support devices often rely on manpower or temporary mechanical means to provide extrusion force, but these methods are difficult to ensure the uniformity and continuity of the extrusion force. As a result, the formwork may become locally deformed or loose during the pouring process.

[0028] The expansion base 300 is provided with a counterweight extrusion assembly 600 for driving the expansion base 300 to perform extrusion movement, the inner support bracket 200 is provided with a counterweight assembly 700 that cooperates with the counterweight extrusion assembly 600, the expansion base 300 is provided with a telescopic extrusion assembly 500 for extruding the template, the stable base plate 100 is provided with a counterweight groove 101 that cooperates with the counterweight assembly 700, and the stable base plate 100 is provided with a counterweight buckle plate 102 that cooperates with the counterweight groove 101.

[0029] Specifically, the stable base plate 100 serves as the supporting foundation of the entire device, ensuring that the device is stably placed above the drain ditch. The inner support bracket 200 is located in the drain ditch, providing a support point for the expansion base frame 300, and realizing the expansion function by cooperating with the counterweight extrusion assembly 600. The expansion base frame 300 is connected to the inner support bracket 200 by a rotational connection, and can be expanded outward under the action of the counterweight extrusion assembly 600 to achieve stable support for the template. The movable slide rail assembly 400 provides a sliding track for the expansion base frame 300 to ensure its smooth expansion and contraction. The counterweight extrusion assembly 600 uses the gravity of the counterweight assembly 700 to drive the expansion of the expansion base frame 300 through mechanical transmission. The telescopic extrusion assembly 500 achieves tight fixation and stable support of the template by adjusting the relative position of the support frame 520 and the extrusion frame 510. The counterweight assembly 700 provides the necessary gravity and is the key to the operation of the counterweight extrusion assembly 600.

[0030] Furthermore, the movable slide rail assembly 400 includes two movable slides 410 symmetrically arranged on the stable base plate 100, and a movable rail groove 420 is provided on the movable slide 410, and a movable seat 430 that slides with the movable rail groove 420 is provided in the movable rail groove 420, and a limiting screw 440 that cooperates with the expansion support base 300 is provided on the movable seat 430.

[0031] Specifically, the movable rail assembly 400 is arranged on the bottom surface of the stable base plate 100 and slides with the top of the expansion base frame 300, allowing the expansion base frame 300 to adjust its position within a certain range to accommodate drains of different sizes. This design improves the adaptability and flexibility of the device. In actual construction, the width and shape of the drain ditch may vary, especially in complex terrain or special engineering conditions. The movable rail assembly 400 allows the expansion base frame 300 to be fine-tuned as needed to ensure that each expansion base frame 300 can accurately fit the side wall of the drain ditch and provide uniform and effective support. By adjusting the position of the movable seat 430, effective support for drains of different widths can be achieved, avoiding deformation of the formwork or deterioration of the concrete pouring quality due to uneven support. Through its unique design, the movable rail assembly 400 significantly improves the flexibility and adaptability of the drain ditch stabilizing internal support device, enabling it to better cope with various complex construction conditions. At the same time, it also simplifies the operation process and improves construction efficiency and safety.

[0032] Furthermore, the telescopic extrusion assembly 500 includes a plurality of extrusion frames 510 arranged on the inner support bracket 200, the extrusion frame 510 is provided with a support frame 520 that slides with the extrusion frame 510, the extrusion frame 510 is provided with a positioning screw 530 that cooperates with the support frame 520, the support frame 520 is provided with a connecting shock-absorbing arm 540, the connecting shock-absorbing arm 540 is provided with a connecting plate 550 connected to the template, and the connecting plate 550 is provided with a connecting screw 560 connected to the template.

[0033] Specifically, the telescopic extrusion assembly 500 includes an extrusion frame 510 and a support frame 520, connected by set screws 530. The shock-absorbing arms and connecting plates 550 on the support frame 520 are used to connect to the formwork, providing horizontal support and preventing deformation during construction. The extrusion frame 510 is fixed to the inner support bracket 200, providing a sliding track for the support frame 520. The extrusion frame 510 provides a sliding path for the support frame 520, ensuring its movement within a predetermined range. The support frame 520 slides along the extrusion frame 510, directly contacting the formwork and applying the extrusion force. The support frame 520 can precisely adjust the pressure on the formwork by sliding and being fixed by set screws 530. The connecting shock-absorbing arms 540 absorb some of the impact force, protecting the formwork from damage caused by excessive extrusion. The connecting plates 550 directly contact the formwork and are fixed by connecting screws 560 to ensure its accurate position. The connecting plates 550 provide a close contact surface with the formwork, ensuring the stability of the formwork during the pouring process.

[0034] Furthermore, the counterweight extrusion assembly 600 includes a counterweight bracket 610 connected to the inner support bracket 200, a counterweight plate 620 that cooperates with the counterweight assembly 700 is provided in the counterweight bracket 610, and a set of driving connecting rods 630 are respectively provided at both ends of the counterweight plate 620. One end of the driving connecting rod 630 is rotatably connected to the counterweight plate 620, and the other end of the driving connecting rod 630 is provided with an extrusion driving member 640 that slides with the counterweight bracket 610.

[0035] The counterweight bracket 610 is provided with a guide unit 650 that cooperates with the extrusion drive member 640, and the extrusion drive member 640 is provided with an inner expansion arm 660. An expansion drive block 670 that is rotatably connected to the inner expansion arm 660 is provided at one end of the inner expansion arm 660 away from the extrusion drive member 640, and the expansion drive block 670 is slidably matched with the expansion base 300.

[0036] Preferably, a set of driving links 630 includes two driving links 630 symmetrically arranged at both sides of the counterweight plate 620 .

[0037] Preferably, a structural design of the guide unit 650 in which two extrusion drive members 640 cooperate is provided.

[0038] First, the guide unit 650 includes a driving groove 651 formed on the counterweight bracket 610 and slidingly engaged with the extrusion driving member 640 .

[0039] Secondly, the guide unit 650 includes a plurality of driving guide rods 652 disposed on the counterweight bracket 610 and slidingly engaged with the extrusion driving member 640 .

[0040] Specifically, the counterweight extrusion assembly 600 is set on the expansion support base 300, and the gravity of the counterweight block 720 drives the expansion support base 300 to perform extrusion movement, thereby enhancing the friction between the device and the side wall of the drainage ditch and ensuring that the device will not move due to the impact during concrete pouring.

[0041] The guide unit 650 includes a driving groove 651 or a driving guide rod 652, which slides with the extrusion driving member 640 to guide the movement of the extrusion driving member 640, ensure the stable movement of the counterweight plate 620, and improve the operating accuracy of the device.

[0042] Furthermore, the counterweight assembly 700 includes a counterweight frame 710 disposed on the counterweight plate 620 , and a counterweight block 720 is disposed in the counterweight frame 710 .

[0043] Furthermore, the counterweight assembly 700 further includes a counterweight net bag 730 , in which counterweight bricks are arranged, and a connecting rope 740 connected to the counterweight plate 620 is arranged on the counterweight net bag 730 .

[0044] Specifically, the counterweight assembly 700 cooperates with the counterweight extrusion assembly 600. The counterweight assembly 700 can adjust the position and weight of the counterweight through the cooperation of the counterweight slot 101 and the counterweight buckle plate 102 to adapt to different construction requirements.

[0045] During use, the stabilizing base plate 100 is first placed over the drain ditch, ensuring that the bottom surface of the stabilizing base plate 100 is in close contact with the edge of the drain ditch. The internal support bracket 200 is then lowered into the drain ditch along with the stabilizing base plate 100. Initially, the expansion base frame 300 is pivotally connected to the internal support bracket 200 to maintain a retracted position, facilitating installation. The movable slide 410 in the movable rail assembly 400 provides a sliding track for the expansion base frame 300. The initial position of the expansion base frame 300 can be adjusted using set screws 530.

[0046] The counterweight block 720 or counterweight brick in the counterweight assembly 700 is connected to the counterweight plate 620 via the counterweight frame 710 or counterweight net 730. It is placed in the counterweight slot 101 on the stable base plate 100 and secured by the counterweight buckle plate 102. When the counterweight extrusion assembly 600 begins operation, the counterweight plate 620 moves downward due to gravity, driving the extrusion drive member 640 to slide within the guide unit 650 via the drive link 630. The movement of the extrusion drive member 640 further drives the inner expansion arm 660 to rotate. The expansion drive block 670, connected to the other end of the inner expansion arm 660, pushes the expansion base 300 to expand outward along the movable slide rail assembly 400 until it reaches the predetermined position.

[0047] As the expansion base 300 expands, the telescopic extrusion assembly 500 begins to function. The support frame 520 on the extrusion frame 510 is adjusted to the appropriate position using positioning screws 530. The connecting shock-absorbing arm 540 and connecting plate 550 securely connect the formwork to the support frame 520. Connecting screws 560 on the connecting plate 550 securely fasten the formwork to the telescopic extrusion assembly 500, ensuring that the formwork will not shift or deform due to external forces during the concrete pouring process.

[0048] After the formwork is supported and stabilized, subsequent construction operations such as concrete pouring can be carried out. After construction is completed, the counterweight extrusion assembly 600 is reversed to retract the expansion support frame 300 back to its original position. The entire internal support device can then be easily removed, facilitating subsequent maintenance and inspection of the drainage ditch.

[0049] The technical features not described in the present invention can be realized by or by adopting the existing technology, and will not be described in detail here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples.
