Description

Technical Field

[0001] This utility model relates to the field of tooling technology for adjusting interlayer spacing, specifically a novel basket tightening device for construction. Background Technology

[0002] Traditional basket tensioners have a round hole at one end and a hook at the other, severely limiting their application. They are generally only used to tighten loose guy lines, offering a single function: tightening ropes tied to an object or securing guy ropes. However, in tunnel construction, before the secondary lining is poured, the reinforcing bars need to be positioned to ensure the spacing between adjacent bars and between inner and outer layers meets construction requirements. Existing basket tensioners cannot accurately adjust the spacing between reinforcing bar layers. Therefore, how to modify existing basket tensioners to meet the layer spacing adjustment needs of tunnel construction is a technical problem that needs to be solved. Utility Model Content

[0003] The problem to be solved is to modify the existing tightening baskets to meet the needs of adjusting the spacing between tunnel layers.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel turnbuckle tightener for construction, comprising an open-body turnbuckle tightener, the open-body turnbuckle tightener including a rotating adjusting ring, a threaded screw 1 and a threaded screw 2 respectively threadedly engaged with the rotating adjusting ring, and a first open clamping portion and a second open clamping portion disposed at both ends; the rotating adjusting ring, the threaded screw 1, and the threaded screw 2 are coaxially connected; and the threaded screw 1 is connected to the first open clamping portion, and the threaded screw 2 is connected to the second open clamping portion; the rotating adjusting ring drives the threaded screw 1 and the threaded screw 2 to synchronously move in opposite directions to adjust the distance between the first open clamping portion and the second open clamping portion.

[0020] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model:

[0021] To address the problems mentioned in the background art, this utility model provides a novel turnbuckle tightener for construction. As shown in the figure, the open-type turnbuckle tightener 2 of this utility model connects to the template 1 as the main structure of the device. The template 1 includes an inner template 11 and an outer template 12. The open-type turnbuckle tightener 2 adjusts the spacing between the inner template 11 and the outer template 12 through an internal threaded mechanism. The open-type turnbuckle tightener 2 adopts an "open-type" design with openings at both ends, allowing the clamping part to freely adjust its angle and position, adapting to templates or reinforcing bars of different sizes. This improves the traditional single-function turnbuckle into a bidirectional adjustable device, expanding its application range (such as template reinforcement, reinforcing bar layer spacing adjustment, etc.). The open-type turnbuckle tightener 2 includes a rotating adjusting ring 3, a threaded screw 4 and a threaded screw 6 respectively threadedly engaged with the rotating adjusting ring 3, and a first open clamping part 5 and a second open clamping part 7 located at both ends. The rotating adjusting ring 3, the threaded screw 4, and the threaded screw 6 are coaxially connected. The rotating adjusting ring 3 drives the threaded screw 4 and the threaded screw 6 to move synchronously in opposite directions. Through manual rotation, the total displacement of the two screws reaches 5mm with each rotation, achieving precise control of the clamping part spacing. The rotational force of the rotating adjusting ring 3 is converted into the linear displacement of the threaded screw 4 and the threaded screw 6, providing a stable and controllable adjustment method and avoiding the offset problem caused by unilateral force in traditional tighteners. Furthermore, threaded screw 4 is connected to the first open clamping part 5, and threaded screw 6 is connected to the second open clamping part 7. Threaded screw 4 and threaded screw 6 convert rotational motion into linear displacement through threaded engagement, directly driving the corresponding clamping parts to move. The thread depth of threaded screw 4 and threaded screw 6 is 1.5mm, the trough spacing is 2.5mm, and the single-cycle rotational displacement is 2.5mm, ensuring a high adjustment accuracy of 2.5mm per cycle. Both threaded screw 4 and threaded screw 6 are 150mm long, with an effective stroke of 150mm to prevent overtravel and thread slippage. The two screws move synchronously in opposite directions (total 5mm / cycle), quickly adjusting the spacing while maintaining balanced force. The rotating adjustment ring 3 drives threaded screw 4 and threaded screw 6 to move synchronously in opposite directions to adjust the spacing between the first open clamping part 5 and the second open clamping part 7. The first open clamping part 5 and the second open clamping part 7 directly clamp the inner template 11 and the outer template 12, transmitting the adjustment force. The adjustable spacing range of the open-type turnbuckle tightener 2 is 300mm to 600mm.

[0022] Embodiment 1 of this utility model is as follows Figure 2 As shown, the openings of the first opening clamping part 5 and the second opening clamping part 7 are concave, and the direction of the concave opening is perpendicular to the transverse axis of the rotating adjustment ring 3. This arrangement is suitable for adjusting the distance between the two side walls and makes it easy to clamp the wall; Embodiment 2 is as follows. Figure 3The openings of the first and second opening clamping parts 5 and 7 shown are U-shaped, with the direction of the U-shaped opening collinear with the transverse axis of the rotating adjustment ring 3. The inner template 11 and outer template 12 are longitudinally reinforced. If a square steel pipe is used, a U-shaped opening is adopted; Example 3 is as follows. Figure 4 The openings of the first and second opening clamping parts 5 and 7 are arc-shaped, with the direction of the arc-shaped openings collinear with the transverse axis of the rotating adjustment ring 3. If circular steel pipes are used for longitudinal reinforcement of the inner template 11 and outer template 12, arc-shaped openings are employed. The diverse opening forms of the first and second opening clamping parts 5 and 7 adapt to fixing objects of different shapes (such as template edges and reinforcing bars). The opening design enhances clamping stability and prevents slippage. Multi-point fixing is achieved through the movement of the first and second opening clamping parts 5 and 7, ensuring that the inner template 11 and outer template 12 maintain precise spacing during construction. Through the improvement of the proposed solution, the traditional turnbuckle is transformed into an open-type turnbuckle tightener 2. The open-type turnbuckle tightener 2 features open clamping sections at both ends, allowing for diverse opening designs. It can be used in formwork support systems on construction sites. For beams and walls of varying widths and thicknesses, the width at both ends can be adjusted by adjusting the rotation of the open-type turnbuckle tightener 2 to tighten or release the threaded rod. The open-type turnbuckle tightener 2 is simple in design, easy to use, and widely applicable. The thread depth of the open-type turnbuckle tightener 2 is h, typically 1.5mm; the spacing between the troughs of the threaded rod is L, typically 2.5mm; and the lengths of threaded rod 4 and threaded rod 6 are S, which is 150mm. When the open-type turnbuckle tightener 2 rotates one revolution, the displacement of threaded screw 4 and threaded screw 6 is 2.5mm each, and the combined displacement of threaded screw 4 and threaded screw 6 is 5mm. When the rotating adjusting ring 3 rotates one revolution, the effective change distance between the inner template 11 and the outer template 12 is 5mm, which is the width of tightening or loosening. The length of threaded screw 4 and threaded screw 6 is 150mm each. The effective stroke of the open-type turnbuckle tightener 2 is D, which is 150mm. If it is greater than 150mm, the threaded rod will fall off. The adjustable spacing of the open-type turnbuckle tightener 2 should be controlled between 300mm and 600mm.

[0023] The specific implementation steps of the flower basket tightener are as follows:

[0024] Structural assembly: Connect the two ends of the open-type turnbuckle tightener 2 to the first open clamping part 5 and the second open clamping part 7 respectively, and engage with the threaded screw 4 and the threaded screw 6 by rotating the adjusting ring 3.

[0025] Spacing adjustment: Rotate the adjusting ring 3 to drive the threaded screw 4 and the threaded screw 6 to move synchronously in opposite directions. A single rotation makes the total displacement of the two screws 5mm, thereby adjusting the spacing between the first opening clamping part 5 and the second opening clamping part 7.

[0026] Application Scenarios: Template Reinforcement: Fix the first clamping part 6 to the inner template 11, and the second open clamping part 7 to the outer template 12. Rotate the adjusting ring 3 to the required width to tighten the template. Rebar Positioning: Fix the first open clamping part 5 and the second open clamping part 7 to adjacent rebars respectively. Precisely control the rebar spacing by rotating the adjusting ring 3. Parameter Limitations: The effective stroke of the threaded rod is 150mm; exceeding this may cause it to fall off. The adjustable spacing range should be controlled between 300mm and 600mm to ensure structural stability.

[0027] This invention uses a rotating adjusting ring 3 to drive the threaded screws 4 and 6 to move in opposite directions, thereby changing the distance between the first open clamping part 5 and the second open clamping part 7, achieving precise positioning of the inner template 11 and the outer template 12. Through its open-body structure, synchronous adjustment of the dual screws, and the design of the open clamping parts, it solves the problems of traditional tensioners having limited functionality and adjustment range, making it suitable for complex construction scenarios. This device is applicable to the assembly of concrete wall templates of different thicknesses and the positioning of reinforcing bars in tunnel construction. It has the advantages of simple operation, wide applicability, and high adjustment accuracy, solving the technical problem of traditional tensioners having limited functionality and being unable to meet the requirements of layer spacing adjustment.

[0028] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
