Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a rapid support device for steel reinforcement layers based on the linkage of a scale upright and a hook inclined lever. Technical Background

[0002] Reinforcing trestles are temporary support devices used in reinforced concrete construction to fix the spacing of double-layer steel meshes. They are key components to ensure the accurate positioning of the double-layer steel meshes. Their core functions are to maintain the designed spacing between the upper and lower layers of steel bars to ensure reasonable structural stress; to control the thickness of the concrete cover to prevent corrosion or concrete cracking; and to resist construction loads to prevent deformation of the steel mesh.

[0003] In traditional cast-in-place concrete structure construction, the usual sequence is to first lay the lower layer of reinforcing bars, then erect the reinforcing bar support frame, and finally lay the upper layer of reinforcing bars, which needs to be pre-welded or tied for fixation. However, when faced with unforeseen circumstances such as design changes, construction errors, insufficient support, reinforcing bar settlement, or dynamic loads during construction, replacing or modifying the support frame requires locally loosening the reinforcing bars, which may affect the overall structural integrity, significantly impact the construction schedule, delay the delivery date, and increase costs.

[0004] Therefore, there is an urgent need to develop a rapid support device for steel reinforcement layers based on the linkage between the scale upright and the hook inclined lever to efficiently and conveniently add or modify trestles between steel reinforcement layers. Summary of the Invention

[0005] This utility model aims to overcome the problems of difficult operation and low efficiency in adding or modifying trestles between double-layer steel meshes, and provides a rapid support device for steel layer based on the linkage of scale upright and hook inclined lever, which greatly makes the above process more convenient and efficient, and eliminates technical barriers to a certain extent.

[0006] To achieve the above objectives, this utility model provides a rapid support device for steel reinforcement layers based on the linkage of a graduated pole and a hook-shaped inclined lever; it includes a graduated pole, an inclined rod assembly set on the graduated pole, and a height control rod set on the graduated pole.

[0007] The middle part of the diagonal bar assembly is movably mounted on the upright ruler of the pole through an adjustment mechanism to form a lever structure, and the adjustment mechanism can lock the position of the diagonal bar assembly.

[0008] The height control lever can move up and down along the marker ruler and is locked by the lever locking mechanism.

[0009] Furthermore, the bottom of the measuring rod is provided with a base, and the outer wall of the measuring rod in the vertical direction is provided with a scale.

[0010] Furthermore, the diagonal bar assembly includes a diagonal bar body, a hook disposed at one end of the diagonal bar body, and a force-applying pedal disposed at the other end of the diagonal bar body.

[0011] Furthermore, the adjustment mechanism includes a screw and a wing nut. The screw passes radially through the inclined rod body and the marker ruler, and the wing nut is used to install the inclined rod body on the marker ruler.

[0012] Furthermore, the rod locking mechanism includes a U-shaped steel plate and a wing screw. The U-shaped steel plate is disposed at one end of the height control rod, and the open end of the U-shaped steel plate is fitted onto the standard rod ruler. The wing screw passes through the threaded hole of the U-shaped steel plate and contacts the standard rod ruler.

[0013] Furthermore, the inclined rod body is provided with a mounting through hole for the screw to pass through, and the distance between the mounting through hole and the hook is less than the distance between the mounting hole and the force application pedal.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. By using a simple lever consisting of a standard ruler and a diagonal bar, a relatively small force can be applied to the force application pedal to hook the front end of the diagonal bar up the upper steel mesh, saving manpower and improving efficiency.

[0016] 2. Millimeter-level precise height control is achieved through a graduated ruler. The height of the added trestles is selected according to the design elevation of the upper layer of steel bars to achieve precise operation.

[0017] 3. The use of a wing nut in conjunction with the screw facilitates quick and easy locking of the diagonal rod structure, enabling single-person operation and saving labor.

[0018] 4. The device can be reused, reducing construction costs. Attached Figure Description

[0021] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0022] like Figure 1As shown, a rapid support device for steel reinforcement layer based on the linkage between the scale upright and the hook inclined lever includes a scale upright 1, an adjustment mechanism 2, an inclined rod assembly 3, a rod locking mechanism and a height control rod 4;

[0023] The diagonal bar assembly 3 is movably connected to the pole ruler 1 through the adjustment mechanism 2. Specifically, the adjustment mechanism can realize the rotational connection between the diagonal bar assembly 3 and the pole ruler 1, and can lock and fix the rotational position. More specifically, the middle part of the diagonal bar assembly 3 is movably set on the pole ruler 1 through the adjustment mechanism 2 to form a lever structure.

[0024] In one embodiment, the diagonal bar assembly 3 includes a diagonal bar body, a hook 31 disposed at one end of the diagonal bar body, and a force-applying pedal 32 disposed at the other end of the diagonal bar body; and the diagonal bar body is provided with a mounting through hole for the adjustment mechanism 2, and the distance between the mounting through hole and the hook 31 is less than the distance between the mounting hole and the force-applying pedal 32, thus forming the above-mentioned lever structure.

[0025] In one embodiment, the adjustment mechanism 2 includes a screw 21 and a wing nut 22. The screw 21 passes radially through the inclined rod body and the marker ruler 1, and the inclined rod body is mounted on the marker ruler 1 by the wing nut 22.

[0026] The height control lever 4 is set on the vertical ruler 1 and can be moved up and down along the vertical direction of the vertical ruler 1 for adjustment.

[0027] In one embodiment, the height control lever 4 can move up and down along the marker ruler 1 and is locked by a lever locking mechanism. The lever locking mechanism includes a U-shaped steel plate 41 and a wing screw 42. The U-shaped steel plate 41 is disposed at one end of the height control lever 4, and the open end of the U-shaped steel plate 41 is fitted onto the marker ruler 1. The wing screw 42 passes through the threaded hole of the U-shaped steel plate 41 and contacts the marker ruler 1.

[0028] In one embodiment, the bottom of the marker ruler 1 is provided with a base to ensure the stability of the marker ruler 1. The outer wall of the marker ruler 1 in the vertical direction is provided with a scale to facilitate observation of the movement position of the height control rod 4. Example

[0029] Taking the process of adding stirrups as an example, before using this device, determine the height difference between the upper and lower layers of reinforcing mesh and the location where stirrups need to be added. Place the measuring rod 1 vertically on the lower layer of reinforcing mesh, or through the reinforcing mesh and on the ground, ensuring it is placed stably. Loosen the wing screw 42 and adjust the diagonal rod assembly 3 so that the hook 31 hooks onto the upper layer of reinforcing mesh. Observe the scale and adjust the height control rod 4 to the target scale. Hold the measuring rod 1 with one hand and apply pressure to the force application pedal 32 with the other foot until the upper layer of reinforcing mesh reaches the height control rod 4. Tighten the wing nut 22 to fix the angle of the diagonal rod assembly 3. Then select a suitable stirrup to add between the two reinforcing meshes. After removing the device, a stable space is formed between the reinforcing meshes, and concrete can be poured directly. Similarly, after hooking up the upper layer of reinforcing mesh, the unnecessary stirrups can be removed.

[0030] This utility model provides a rapid support device for steel reinforcement layers based on the linkage of a graduated upright and a hook-shaped inclined lever. When it is necessary to add, remove, or modify trestles during the construction of cast-in-place concrete structures, using this device can help construction personnel operate quickly, efficiently, accurately, and conveniently. To a certain extent, it overcomes the limitations of limited manpower and technology, and reduces the time and labor costs of construction.
