Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a positioning component for steel reinforcement pouring. Background Technology

[0002] After the reinforcing bars of walls, columns, and beams are tied, formwork needs to be erected around them for concrete pouring. Formwork erection must strictly follow the drawings; therefore, construction lines must be marked on the ground, aligning the formwork edges with these lines to determine the formwork's position. However, the length of beams and walls is considerable, and the gap between the construction lines and the formwork edges increases with their length, causing the formwork to deviate from its correct position. To address this, positioning bars need to be welded to the main reinforcing bars of the wall and beam. The ends of these positioning bars should be flush with the two sides of the wall and beam. During formwork erection, the formwork surface should rest against the positioning bars, and then the positioning bars should be directly poured into the beam and wall. Alternatively, when marking the wall and beam edges, auxiliary lines are typically marked 20 centimeters away from each edge to check the correct formwork erection and to inspect the dimensions and position of the poured wall and beam. During formwork erection, holes are drilled on the auxiliary lines, positioning bars are inserted into the holes, and then a 20-centimeter-wide formwork is placed between the positioning bars and the main reinforcing bars of the wall and beam, with the back of the formwork resting against the positioning bars. Compared to the first method, it does not require cutting steel bars to a specific length, nor does it involve casting steel bars into beams and walls, thus avoiding some damage to the main structure. However, it does require drilling holes in the ground, and the dust generated during drilling can cause some harm to the human body. Furthermore, it requires custom-made templates of specific dimensions. Utility Model Content

[0003] The purpose of this invention is to provide a positioning component for reinforcing steel pouring, in order to solve the above-mentioned problems.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A positioning component for reinforcing steel pouring includes multiple mounting seats. Each mounting seat has a fixing component at its bottom and a cavity within it. A horizontal worm and an internally threaded cylinder are disposed within each cavity. The worm's two ends are rotatably connected to the left and right side walls of the cavity, respectively, and extend to the outside of the cavity. The internally threaded cylinder's two ends are rotatably connected to the front and rear side walls of the cavity, respectively. The internally threaded cylinder is located above the worm, and their axial directions are perpendicular to each other. A worm wheel is fixedly connected to the outer wall of the internally threaded cylinder, and the worm and worm mesh. A screw is threadedly connected to the internally threaded cylinder. The screw is fixedly connected to a parallel limiting rod via a connecting piece. The limiting rod passes through the mounting seat and is slidably connected to it. The component also includes a connecting rod that passes through the worms on the multiple mounting seats along their axial direction, thereby connecting the multiple positioning components. The connecting rod is fixedly connected to the worm via a connecting component.

[0006] Using the above technical solution, the connecting rod passes through the worm gear of each positioning component, and is fixed to the worm gear by the connecting component. Then, the positioning component is fixed to the auxiliary line by the fixing component. The end of the limiting rod is flush with the auxiliary line. Rotating according to the width of the template rotates the connecting rod, which drives the worm gear of each positioning component to rotate. The worm gear drives the internal threaded cylinder to rotate through the worm wheel it meshes with. The rotation of the internal threaded cylinder drives the screw connected to it to move. The screw drives the limiting rod to move a corresponding distance. The template is placed between the positioning component and the main reinforcement of the wall beam. The back of the template rests against the end of the limiting rod, and the bottom edge of the template coincides with the edge of the wall beam. This ensures that the template is placed in the correct position, avoiding errors in the size and position of the beam and wall after pouring. It eliminates the need to cut steel bars of a specific length, weld them to the main reinforcement, and then pour them together, thus avoiding damage to the main structure. It also eliminates the need to drill holes in the ground, which generates dust that may affect human health, and eliminates the need to make templates of a specific width so that their bottom edge coincides with the edge of the wall beam after resting against the positioning reinforcement standing on the auxiliary line.

[0007] Preferably, the limiting rod is provided with a scale line, and the position of the zero scale line on the limiting rod is flush with the opening of the through hole of the mounting base through which it passes.

[0008] Using the above technical solution, depending on the template width, the connecting rod is rotated to make the screw drive the limiting rod to move. Referring to the scale line, the limiting rod is moved an appropriate distance so that the distance from the end of the limiting rod to the edge of the wall beam is equal to the width of the template.

[0009] Preferably, the connector is a bolt, which is threaded onto the outer wall of the worm located outside the cavity of the mounting seat, and the end of the bolt contacts the connecting rod passing through the worm.

[0010] Using the above technical solution, the connecting rod is passed through the worm gear of the positioning component, and the bolt is tightened to make it press against the connecting rod, thereby fixing the connecting rod and the worm gear.

[0011] Preferably, the connecting rod can be a wooden rod available on site, which is passed through the worm gear of each positioning component. Then, the connecting rods passing through each positioning component are connected in series. When connecting, wooden strips are placed on two adjacent wooden rods, and then the wooden strips are fixed to the wooden rods with nails, thereby fixing the two connecting rods.

[0012] The above technical solution is easy to obtain materials, and connecting rods of different lengths can be made according to beams and walls of different lengths.

[0013] Preferably, the fastener is a wall nail, and a connecting plate is fixedly connected to the bottom of the mounting base. The connecting plate has two round holes, and the line connecting the centers of the two round holes is perpendicular to the axis of the screw. A wall nail passes through each round hole.

[0014] Using the above technical solution, the two round holes on the positioning component connecting plate are placed on the auxiliary line, and then two wall nails are passed through the two round holes and nailed to the auxiliary line to fix the positioning component.

[0022] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0023] See Figures 1 to 6A positioning component for reinforcing steel pouring includes multiple mounting seats 1. Each mounting seat 1 has a connecting plate 10 integrally formed at its bottom, with two circular holes, each through which a wall nail 11 passes. Each mounting seat 1 has a cavity containing a horizontal worm gear 2 and an internally threaded cylinder 3. The two ends of the worm gear 2 are rotatably connected to the left and right side walls of the cavity of the mounting seat 1, respectively, and extend to the outside of the cavity. Bolts 9 are threadedly connected to the outer wall of the worm gear 2 outside the cavity of the mounting seat 1. The two ends of the internally threaded cylinder 3 are rotatably connected to the front and rear side walls of the cavity, respectively. The internally threaded cylinder 3 is located above the worm gear 2, and the axial directions of the two are perpendicular to each other. A worm wheel 4 is integrally formed on the outer wall of the internally threaded cylinder 3, and the worm wheel 4 meshes with the worm gear 2. The internally threaded cylinder 3 is threadedly connected to a screw 5. The screw 5 is fixedly connected to a parallel limiting rod 6 via a connecting piece. The limiting rod 6 passes through the mounting base 1 and is slidably connected to the mounting base 1. The limiting rod 6 is provided with a scale line 8, and the position of the zero scale line 8 on the limiting rod 6 is flush with the opening of the through hole of the mounting base 1 through which it passes. It also includes a connecting rod 7, which passes through the worm gear 2 of multiple positioning components along its axial direction, thereby connecting the multiple positioning components. The end of the bolt 9 on the worm gear 2 contacts the connecting rod 7 passing through the worm gear 2.

[0024] Working principle: Insert the screw 5 of each positioning component onto a wooden rod, then place each positioning component on the auxiliary line, aligning the two round holes on the positioning component connecting plate 10 with the auxiliary line. Insert wall nails 11 into each round hole, securing the two wall nails on the auxiliary line, thus fixing the positioning component. The end of the limiting rod 6 is flush with the auxiliary line. Then, place wooden strips on the wooden rods of two adjacent positioning components, and fix the wooden strips to the two wooden rods with nails, thus connecting the wooden rods together. Tighten the bolt 9 to press against the connecting rod 7, thus fixing the connecting rod 7 to the worm gear 2. Rotate according to the width of the template, rotating the connecting rod 7. The connecting rod 7 drives the worm gear 2 of each positioning component to rotate. The worm gear 2, through its meshing worm wheel 4, drives the internal threaded cylinder 3 to rotate. The rotation of the internal threaded cylinder 3 drives the screw 5 threadedly connected to it to move. Referring to the scale line 8, the screw 5 drives the limiting rod 6 to move a corresponding distance. The distance from the auxiliary line to the beam wall edge line minus the distance moved by the limiting rod 6 equals the width of the template. The template is placed between the positioning piece and the main reinforcing bars of the wall beam, with the back of the template resting against the end of the limiting rod 6. The bottom edge of the template coincides with the edge of the wall beam, thus ensuring the template is placed in the correct position and preventing errors in the size and position of the beam and wall after pouring. This eliminates the need to cut reinforcing bars to a specific length, weld them to the main reinforcing bars, and then pour the concrete together, thus avoiding damage to the main structure. Furthermore, it eliminates the need to drill holes in the ground, avoiding dust that could affect human health, and it eliminates the need to create templates of a specific width so that their bottom edge coincides with the edge of the wall beam after resting against the positioning bars erected on the auxiliary line.
