Description

Technical Field

[0001] This utility model relates to the field of building decoration tools technology, specifically a combined measuring and positioning template for custom stair treads. Background Technology

[0002] As a core component of vertical transportation in buildings, the dimensional accuracy of staircases—including tread height, width, and depth—directly affects safety and comfort. Traditional wooden or steel formwork, when assembled on-site, is prone to dimensional deviations due to material deformation and accumulated splicing errors. For example, traditional staircase pouring methods require first nailing wooden boards to create a staircase shape mold before pouring concrete step by step. However, these wooden molds are often dismantled using excessive force, and the dismantled formwork is generally not reusable. Furthermore, the treads lack cover plates; they are simply filled with concrete and smoothed. Adding anti-slip grooves requires secondary construction, resulting in low efficiency and difficulty in guaranteeing accuracy.

[0003] Chinese patent CN223003739U discloses a stair tread template with a slotted positioning component, comprising: a stair template base plate, configured as an inclined rectangular plate, with symmetrically arranged supporting side plates at both ends of the base plate, the supporting side plates being installed at the upper end of the base plate to form the main body of the stair tread template support; the stair template base plate and the supporting side plates form a U-shaped inclined structure. This stair tread template with a slotted positioning component uses a splicing installation structure with the supporting side plates installed at the upper end of the base plate. Bottom and top inserts of the stair treads at both ends of the supporting side plates are used to cooperate with the supporting side plates for support. The distance and thickness between the templates can be adjusted and customized according to different stair design requirements, making it suitable for various types of stair tread construction. The slotted structure achieves precise positioning, ensuring consistent stair tread dimensions and improving the quality and aesthetics of the staircase.

[0004] When using the aforementioned slot-type positioning component stair tread template, the tread template is usually only suitable for rectangular stair structures and cannot be adjusted accordingly for irregular stair shapes such as arcs or spirals. This results in the need for manual processing, which not only increases material waste but may also lead to dimensional deviations due to insufficient splicing precision.

[0005] To address this issue, the present invention provides a combined measurement and positioning template for custom stair treads. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a combined measurement and positioning template for custom stair treads. This solves the problem that, when using the aforementioned slot-type positioning component stair tread template, the template typically only fits rectangular stair structures and cannot be adjusted for irregularly shaped staircases such as arcs or spirals. This necessitates manual processing, which not only increases material waste but may also lead to dimensional deviations due to insufficient splicing precision.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a combined measuring and positioning template for custom stair treads, comprising a template body, an adjustment component installed inside the template body, and a support component snapped into the bottom of the template body; The adjustment component includes a mounting groove, a telescopic sleeve rod is fixed to the inner wall of the mounting groove, a sliding groove is opened inside the telescopic sleeve rod, a main bone rod is slidably connected in the sliding groove, a rotating groove is opened at the other end of the main bone rod, a hinge shaft is hinged in the rotating groove, a collar is sleeved and fixed in the middle of the hinge shaft, and a connecting bone rod is fixed at the other end of the collar. A limiting block is fixed at one end of the main skeleton near the sliding groove, and the limiting block matches the sliding groove.

[0008] Preferably, both the telescopic sleeve rod and the main skeleton rod have a first limiting groove on their sides, and an insert rod is movably inserted into the first limiting groove.

[0009] Preferably, the side of the main bone rod near the hinge shaft is set as an inclined surface, and both the left and right ends of the connecting bone rod are matched with the inclined surface of the main bone rod.

[0010] Preferably, a positioning plate is fixed to the side of the template body, a slot is provided in the positioning plate, a positioning plate is movably inserted in the slot, and a second limiting groove is provided on the side of both the positioning plate and the positioning plate, and a limiting rod is movably inserted in the second limiting groove.

[0011] Preferably, the support assembly includes a mounting slot, in which a support plate is inserted. Extension blocks are fixed at both ends of the support plate, and a support leg is fixed at the bottom of the extension block. A support plate is welded to the bottom of the support leg, and a shock-absorbing pad is installed at the bottom of the support plate.

[0012] Preferably, a spring damper is threaded onto the top of the support plate, and the spring damper is mounted on the side of the support leg.

[0013] Beneficial effects This invention provides a combined measuring and positioning template for custom stair treads. Compared with the prior art, it has the following advantages: (1) A combined measuring and positioning template for custom stair treads, by setting an adjustment component, allows the modular template to be stretched in the groove according to the actual situation. Then, by taking out the positioning rod on the side of the template, the adjustment blocks on both sides of the template can be bent and adjusted according to the actual curvature of the stair. This allows the step template to be adjusted to the same degree as the actual curvature of the stair. This not only saves the time of secondary manual processing, but also saves material waste. At the same time, by setting the positioning component, the step template after the curvature is adjusted can be positioned, so that the step template can maintain its own stability when the step template is poured and shaped, thereby avoiding the situation of pouring deviation of the stair due to template displacement.

[0014] (2) A combined measuring and positioning template for custom stair treads, which improves the installation stability of the template on the ground by setting support components, and can also prevent the template from sinking or deforming due to the weight of the concrete during concrete pouring. At the same time, by setting a shock absorption device, the template can be prevented from being affected by the vibration generated by the pile driver and concrete vibrator in the construction environment, thereby preventing the template from shaking or displacing.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please see Figure 1-3 A combined measurement and positioning template for custom stair treads includes a template body 1, an adjustment component 2 installed inside the template body 1, and a support component 3 snapped onto the bottom of the template body 1. The adjustment component 2 includes a mounting groove 21, a telescopic sleeve rod 22 fixed to the inner wall of the mounting groove 21, a sliding groove 28 inside the telescopic sleeve rod 22, a main skeleton rod 23 slidably connected in the sliding groove 28, a rotating groove 24 at the other end of the main skeleton rod 23, a hinge shaft 25 hinged in the rotating groove 24, a collar 26 fixed in the middle of the hinge shaft 25, and a connecting skeleton rod 27 fixed at the other end of the collar 26. The main skeleton rod 23 and the connecting skeleton rod 27 are hinged so that when the template body 1 needs to be bent, the main skeleton rod 23 and the connecting skeleton rod 27 can be bent in a specific direction, thereby achieving the function of adjusting the external shape of the template body 1. A limiting block 29 is fixed at one end of the main bone rod 23 near the sliding groove 28. The limiting block 29 matches the sliding groove 28. The outer diameter of the sliding groove 28 is larger than the diameter of the main bone rod 23, and the diameter of the limiting block 29 matches the sliding groove 28, thereby preventing the main bone rod 23 from detaching from the telescopic sleeve rod 22. Both the telescopic sleeve rod 22 and the main bone rod 23 have a first limiting groove 210 on their sides. An insert rod 211 is movably inserted into the first limiting groove 210. The insert rod 211 is used to limit and fix the main bone rod 23 and the telescopic sleeve rod 22 after stretching, so as to prevent the main bone rod 23 from sliding in the telescopic sleeve rod 22 when the template body 1 is bent. The side of the main rib 23 near the hinge shaft 25 is set as an inclined surface. Both ends of the connecting rib 27 are matched with the inclined surface of the main rib 23. The inclined surface setting allows the connecting rib 27 to be hinged at a large angle on the side of the main rib 23 when the main rib 23 and the connecting rib 27 are bent, thereby adapting to the bending curvature of the template body 1. A positioning plate 212 is fixed on the side of the template body 1. A slot 213 is provided in the positioning plate 212. A positioning plate 214 is movably inserted in the slot 213. A second limiting groove 215 is provided on the side of both the positioning plate 212 and the positioning plate 214. A limiting rod 216 is movably inserted in the second limiting groove 215. The positioning plate 214 is used to provide external positioning for the bent template body 1, thereby effectively preventing the template body 1 from deforming during the pouring process.

[0019] In this embodiment, when the template body 1 needs to be laid on a curved staircase floor, the template body 1 is first stretched so that the telescopic sleeve 22 inside the template body 1 slides and stretches with the main skeleton 23, thereby exposing the main skeleton 23 and the connecting skeleton 27 from the template body 1. Then, the insert rod 211 is movably inserted into the first limiting groove 210 opened in the main skeleton 23 and the telescopic sleeve 22 to position and fix the main skeleton 23. Then, according to the actual curvature required by the template body 1, the main skeleton 23 and the connecting skeleton 27 are aligned. 27 is hinged through hinge shaft 25, so that connecting rod 27 bends on the side of main rod 23, thereby allowing the external structure of template body 1 to be bent. Then, when template body 1 is bent to a suitable angle, positioning plate 214 is inserted into positioning card plates 212 on both sides of template body 1, so that positioning plate 214 positions the bent template body 1, and positioning plate 214 is limited and fixed by limiting rod 216, so that template body 1 will not deform during later pouring.

[0020] Example 2: Please see Figure 1-4 Based on Embodiment 1, this embodiment provides a technical solution for a support component 3, which includes a mounting slot 31. A support plate 32 is inserted into the mounting slot 31. Extension blocks 33 are fixed at both ends of the support plate 32. Support legs 34 are fixed at the bottom of the extension blocks 33. A support plate 35 is welded to the bottom of the support legs 34. A shock-absorbing pad 36 is installed at the bottom of the support plate 35. The shock-absorbing pad 36 is used to effectively isolate a small amount of vibration, so that the vibration is isolated from the support plate 32. A spring damper 37 is threaded onto the top of the support plate 35. The spring damper 37 is installed on the side of the support leg 34. The spring damper 37 can disperse the vibration force transmitted to the support plate 35, thereby greatly reducing the impact of the vibration force on the support plate 32.

[0021] In this embodiment, when installation on the ground is required, the support plate 32 is first movably inserted into the mounting slot 31 at the bottom of the template body 1, thereby isolating the template body 1 from the ground by the support plate 32, preventing the template body 1 from directly contacting the ground. Then, when the vibration force generated by machines such as pile drivers and concrete vibrators on the construction site is transmitted to the support plate 35 through the ground, the shock-absorbing pad 36 at the bottom of the support plate 35 can isolate part of the vibration force, and the remaining vibration force is dispersed by the spring damper 37 on the side of the support leg 34, so that the vibration force cannot be transmitted to the support plate 32, thereby avoiding any impact on the template body 1.
