[0001] This utility model relates to the field of building engineering technology, and in particular to a positioning steel plate device. Background Technology

[0002] Currently, the positioning of reinforcing bars in the transfer layer of prefabricated buildings on construction sites is usually achieved by using wooden formwork, square steel pipe clamps for temporary fixation, or angle steel for positioning and fixation. However, the above methods have the disadvantages of poor positioning accuracy and the inability to adjust the height of the positioning device, which makes the extension length of the vertical reinforcing bars uncontrollable, resulting in poor overall performance and affecting the quality of construction.

[0003] Therefore, how to improve the efficiency of rebar positioning and enhance construction quality is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning steel plate device for high-efficiency rebar positioning, thereby improving construction quality.

[0008] The elevation adjustment section is used to adjust the height of the positioning steel plate body from the ground.

[0009] Optionally, in the above-mentioned positioning steel plate device, the reserved hole of the vibrator extends along the length direction of the positioning steel plate body, and the positioning holes of the reinforcing bars are distributed at both ends of the reserved hole of the vibrator.

[0010] Optionally, in the above-mentioned positioning steel plate device, the elevation adjustment part includes an adjustment rod, a support block, and a locking structure. The positioning steel plate body has adjustment mounting holes penetrating two opposite sides of the positioning steel plate body. The adjustment rod passes through the adjustment mounting holes. The support block is attached to the side of the elevation adjustment part facing the ground and can move along the extension direction of the adjustment rod to support the positioning steel plate body. The locking structure is used to restrict the movement of the support block on the adjustment rod.

[0011] Optionally, in the above-mentioned positioning steel plate device, the support block is provided with a threaded hole, and the adjusting rod is provided with a thread that mates with the threaded hole, so that the adjusting rod and the support block are connected by threads to form the locking structure.

[0012] Optionally, in the above-mentioned positioning steel plate device, the locking structure includes a clamp disposed on the support block, and the support block is clamped and fixed to the adjusting rod by the clamp.

[0013] Optionally, in the above-mentioned positioning steel plate device, the adjusting rod is provided with scale markings for indicating the adjustment distance.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The core of this utility model lies in providing a positioning steel plate device for high-efficiency rebar positioning, thereby improving construction quality.

[0029] like Figure 1 As shown in the figure, this utility model discloses a positioning steel plate device, including a positioning steel plate body 100 and an elevation adjustment part. The positioning steel plate body 100, having two opposing surfaces, has rebar positioning holes 110 and vibrator pre-drilling holes 120. Both the rebar positioning holes 110 and the vibrator pre-drilling holes 120 penetrate both surfaces of the positioning steel plate body 100. During use, the vertical rebars of the transition layer are inserted into the rebar positioning holes 110, enabling rapid positioning of the rebars. After concrete pouring, the vibrator can extend into the concrete through the vibrator pre-drilling holes 120, facilitating vibration and mixing of the concrete and eliminating voids in the concrete. During the placement of the positioning steel plate body 100, the height of the positioning steel plate body 100 can be adjusted via the elevation adjustment unit. By adjusting the height of the positioning steel plate body 100, the length of the vertical reinforcing bars extending from the reinforcing bar positioning holes 110 can be controlled. Simultaneously, this adjustment ensures that the bottom surface of the positioning steel plate body 100 is at the same height as the finished concrete structure surface, guaranteeing that the height of the hardened concrete structure meets the construction requirements. Therefore, the positioning steel plate device provided in this embodiment achieves adjustable height of the positioning steel plate body 100, controls the extension length of the reinforcing bars, reduces the risk of reinforcing bar misalignment and insufficient extension length of vertical reinforcing bars during construction, improves on-site quality control, and ensures better construction quality.

[0030] In a specific installation and use process, before installing the positioning steel plate body 100, the on-site concrete structure pouring surface, i.e., the beam and slab reinforcement binding, must be cleaned up in a timely manner after the work is completed. After cleaning, the wall control lines of the vertical precast components and the elevation control lines of the concrete structure pouring surface are marked on the site. According to the elevation control lines, the positioning steel plate body 100 is accurately placed and the elevation of the positioning steel plate body 100 is initially adjusted. After the positioning steel plate body 100 is placed, the height of the positioning steel plate body 100 is further adjusted through the elevation adjustment part so that the bottom surface of the positioning steel plate body 100 and the concrete structure pouring surface are at the same height. After the height of the positioning steel plate body 100 is adjusted and its position is stable, the vertical steel bars are cut according to the structural and structural construction drawings. The vertical steel bars are inserted into the wall through the positioning steel bar holes. In order to facilitate the construction personnel to control the extension length of the vertical steel bars more quickly and accurately, PVC pipes with the same extension length as the steel bars are also processed and manufactured. The construction personnel can directly put the PVC pipes onto the extension vertical steel bars to check whether the extension length of the vertical steel bars meets the design requirements. This is simple and quick, improving the efficiency and quality of construction. Then, the vertical steel bars are fixed firmly using wire ties.

[0031] like Figure 1 As shown, the pre-drilled hole 120 for the vibrator provided in this embodiment is located in the middle of the positioning steel plate body 100, and extends along the length of the positioning steel plate body 100 to both ends, increasing the length of the pre-drilled hole 120. This allows the vibrator to move along the pre-drilled hole 120 when vibrating and mixing the poured concrete, increasing the distance the vibrator can move. This allows the vibrator to more thoroughly vibrate and mix the concrete at each location, ensuring the entire concrete structure is compacted and that the solidified concrete structure has high structural strength. Meanwhile, the rebar positioning holes 110 are distributed at both ends of the pre-drilled hole 120, with a gap between the rebar positioning holes 110 and the edges of the pre-drilled hole 120. This reduces the interference of the vibrator in the pre-drilled hole 120 with the rebar in the rebar positioning hole 110 during concrete vibration construction, further ensuring the accuracy of rebar positioning.

[0032] In the positioning steel plate device provided in this embodiment, the elevation adjustment part includes an adjustment rod, a support block, and a locking structure. The positioning steel plate body 100 has an adjustment mounting hole 130 that penetrates both opposite sides of the positioning steel plate body 100. The adjustment rod extends into the adjustment mounting hole 130 of the positioning steel plate body 100. The support block is movably mounted on the adjustment rod and moves up and down along the length of the adjustment rod. The support block is in contact with the ground-facing side of the positioning steel plate body 100 to support and position the positioning steel plate body 100. Then, by moving the support block up and down along the adjustment rod, the height of the positioning steel plate body 100 is adjusted. The locking structure restricts the movement of the support block on the adjustment rod. Thus, after the height adjustment of the positioning steel plate body 100 is completed, the locking structure prevents the support block from moving further, ensuring the stability of the position of the positioning steel plate body 100.

[0033] In one specific embodiment, the support block has a threaded hole penetrating through it, and the adjusting rod has a thread that matches the threaded hole. The support block and the adjusting rod are connected by threads, and rotating the support block allows it to move along the height direction of the adjusting rod through the threads. Simultaneously, the threaded connection forms a locking structure, ensuring the stability of the positioning steel plate body 100 after its height adjustment. In another specific embodiment, the adjusting rod is a bolt, the support block is a nut used with the bolt, and the adjusting mounting hole 130 is also a threaded hole that matches the bolt. The adjusting rod is connected to the support block and the mounting hole via threads, improving the stability of the locking and fixing. After the concrete is poured but before it initially sets, the support bolt and matching nut are disassembled, the positioning steel plate body 100 is removed, and the PVC pipe fitted onto the reinforcing steel is promptly cleaned and recycled for reuse, achieving multiple recycling, environmental protection, and cost savings.

[0034] In another specific embodiment, the locking structure includes a clamp connected to the support block. After the height of the positioning steel plate body 100 is adjusted by moving the support block, it can be clamped onto the adjusting rod by the clamp to limit the displacement of the support block. This ensures that the positioning steel plate body 100 on the support block has good stability. During subsequent concrete pouring and the vibration mixing of the concrete by the vibrator, the positioning steel plate body 100 will not easily fall off or shake, thus improving the stability of the positioning of the steel bars in the steel bar positioning hole 110. Throughout the construction process, the steel bars maintain a high degree of accuracy.

[0035] Furthermore, the adjusting rod is also equipped with scale marks, which are distributed at intervals along the extension direction of the adjusting rod. The distance between two adjacent scale marks can be set according to actual needs. Therefore, during the adjustment of the positioning steel plate body 100, the moving distance of the support block can be clearly and quickly determined according to the scale marks on the adjusting rod, which is conducive to the staff quickly adjusting the positioning steel plate body 100 to a suitable position and significantly improving the efficiency of the height adjustment work of the positioning steel plate body 100.

[0036] like Figure 1 As shown, in the positioning steel plate device provided in this embodiment, the pre-drilled hole 120 of the vibrator extends along the length of the positioning steel plate body 100. Although this increases the opening length of the pre-drilled hole 120 of the vibrator, facilitating concrete pouring and the vibration mixing of the concrete by the movement of the vibrator, the longer pre-drilled hole 120 of the vibrator will reduce the overall structural strength of the positioning steel plate body 100. Therefore, the positioning steel plate device provided in this embodiment also provides multiple angle steels 140. The angle steels 140 are arranged in the pre-drilled hole 120 of the vibrator, and each angle steel 140 is distributed at intervals along the extension direction of the pre-drilled hole 120 of the vibrator. The multiple angle steels 140 strengthen the overall structure of the positioning steel plate body 100 and enhance the rigidity of the positioning steel plate body 100. When subjected to external forces during use, it is not easy to deform, which further improves the accuracy of vertical reinforcement positioning.

[0037] like Figure 1 As shown, each angle steel 140 arranged in the pre-drilled hole 120 of the vibrator is perpendicular to the extension direction of the positioning steel plate body 100. One end of the angle steel 140 is perpendicularly connected to one side of the positioning steel plate body 100, and the other end of the angle steel 140 is perpendicularly connected to the other side of the positioning steel plate. The angle steels 140 are evenly distributed. The vertical connection and uniform distribution of the angle steels 140 are suitable for bearing axial tensile and compressive loads. The force transmission path is direct and the stress distribution is uniform. In this example, the angle steels 140 are connected and fixed to the positioning steel plate body 100 by welding. Right-angle welding can effectively resist bending moment, especially providing stability in frame nodes, and has strong resistance to torsional loads.

[0038] In a specific embodiment, the diameter of the pre-drilled hole 120 of the vibrator is in the range of 90mm-110mm, such as 90mm, 100mm or 110mm. If the initial diameter of the pre-drilled hole 120 is smaller than this range, it may be difficult for the vibrator to move during the concrete vibration mixing process, thus affecting the efficiency of concrete vibration mixing construction. If the initial diameter of the pre-drilled hole 120 is larger than this range, the opening diameter of the pre-drilled hole 120 is larger, which will significantly reduce the overall structural strength of the positioning steel plate body 100. This will make the positioning steel plate body 100 more susceptible to deformation under external forces during construction, and may even cause structural damage, reducing reliability and service life.

[0039] Furthermore, the thickness range of the positioning steel plate body 100 in the positioning steel plate device provided in this embodiment is 3mm-7mm, such as 3mm, 5mm, 6mm, or 7mm. If the thickness of the positioning steel plate body 100 is less than this range, the thinner positioning steel plate body 100 has insufficient structural strength and is prone to deformation and damage during construction. If the thickness of the positioning steel plate body 100 is greater than this range, although the thicker positioning steel plate body 100 has higher structural strength, it increases production costs, which is not conducive to cost savings in the project. Moreover, the thicker positioning steel plate body 100 also... This results in a waste of resources. Meanwhile, the length and width dimensions of the positioning steel plate body 100 can be designed according to the dimensions of the vertical prefabricated components. For example, when the length and thickness of the vertical prefabricated component is 2100mm and 200mm respectively, the length, width and thickness of the positioning steel plate body 100 are 2100mm×300mm×5mm. Furthermore, the diameter, quantity and position of the rebar positioning holes 110 and adjustment installation holes 130 opened in the positioning steel plate body 100 can be designed by those skilled in the art according to actual needs.

[0040] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
