Description

Technical Field

[0001] This utility model belongs to the field of rebar formwork positioning technology, and in particular relates to a rebar formwork positioning device. Background Technology

[0002] In construction engineering, steel reinforcement formwork (or formwork) is used to shape concrete. The accuracy of its installation position is crucial. Steel reinforcement formwork positioning device is a key construction accessory. Its function is to firmly clamp the steel reinforcement formwork before concrete pouring, to prevent the formwork from shifting, deforming or running away due to the lateral pressure of concrete during the pouring process, thereby ensuring that the forming dimensions of the concrete component are consistent with the design.

[0003] Currently, the most common technology is a positioning device consisting of two L-shaped plates. During installation, the two L-shaped plates are placed opposite each other to form a rectangular frame. Then, the frame is fastened to the outside of the steel reinforcement formwork with bolts or other fasteners to achieve the positioning function.

[0004] However, this traditional L-shaped plate assembly structure has obvious limitations, mainly in the following two aspects: First, existing structures are designed to be assembled into rectangles, so their shape is fixed and cannot be adapted. Therefore, they can only be effectively applied to rectangular cross-section formwork. However, they cannot achieve tight wrapping and effective positioning for polygonal, irregular, or irregular cross-section steel reinforcement formwork, which is also common in engineering. Secondly, the existing structure can only position the rebar formwork for a single perimeter. Once the dimensions of the two L-shaped plates are determined, the size of the rectangular frame they form is also fixed. The applicable formwork perimeter is strictly limited to a very small range. When faced with rebar formwork of different sizes and perimeters, the construction party must equip itself with positioning devices of various specifications. This not only increases procurement and inventory costs, but also brings inconvenience to on-site management and selection, resulting in extremely poor flexibility.

[0005] Therefore, it is essential to invent a rebar formwork positioning device. Utility Model Content

[0006] To address the above problems, this utility model proposes a rebar formwork positioning device, and the technical solution used is as follows: A rebar formwork positioning device includes a first frame, a second frame, fastening holes, and fastening bolts. Several first and second frames are provided, with the first and second frames arranged alternately, and adjacent first and second frames are connected by a hinge. At least one fastening hole is provided through each of the first and second frames. A chain composed of the first and second frames wraps around the outer surface of the rebar formwork, and the length of the chain excluding the two outermost first and second frames is equal to the outer circumference of the rebar formwork. The two outermost first or second frames of the chain are fixed together by the fastening holes and fastening bolts.

[0007] Furthermore, the first frame includes a first plate, a second plate, guide posts, studs, and a hexagonal prism. The ends of the first and second plates are respectively hinged and rotatably connected to the corresponding second frame. At least two guide posts are welded to the side of the first plate near the second plate, and the guide posts are slidably disposed inside the second plate. Studs are threadedly installed on both the first and second plates, with the external threads of the studs on the first and second plates having opposite directions. A hexagonal prism is welded between the studs on the first and second plates. At least one fastening hole is provided on the first and second plates. This arrangement allows the device to adapt to steel reinforcement formwork of different sizes.

[0008] Furthermore, the sides of both the first plate and the second plate are fixed with first rubber pads by screws, wherein the outer surface of the first rubber pad is uniformly provided with several protrusions. This arrangement can prevent the device from sliding on the steel reinforcement formwork.

[0009] Furthermore, the second frame includes a third plate and a second rubber pad. The two ends of the third plate are respectively connected to the corresponding first frame by hinge rotation, and at least one fastening hole is provided on the third plate. The second rubber pad is fixed to the side of the third plate by screws. The outer surface of the second rubber pad is evenly provided with several protrusions. This arrangement can further prevent the device from sliding on the steel reinforcement formwork.

[0010] Furthermore, both the first and second frames, which are fitted together with the rebar formwork, are fixed to the rebar formwork through fastening holes and fasteners (bolts or pins). This arrangement can prevent the chain composed of the first and second frames from deforming after installation.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention can wrap the chain composed of the first frame and the second frame around the rebar template. Since the first frame and the second frame are connected by a hinge, the device can adapt to rebar templates of different shapes (such as rectangular or polygonal). After installation, the first frame and the second frame can be fixed to the rebar template by the cooperation of fastening holes and fasteners (bolts or pins), thereby preventing deformation of the chain composed of the first frame and the second frame. The first frame of this utility model can be configured to adjust the distance between the first plate and the second plate by rotating the hexagonal prism with a tool, thereby driving the stud to adjust the overall length of the first frame. By adjusting the overall length of the first frame, this device can be adapted to steel reinforcement formwork of different sizes. Attached Figure Description
