Description

Technical Field

[0001] This invention belongs to the field of integrated casting of stair treads, specifically, it relates to an integrated casting mold for stair treads. Background Technology

[0002] Currently, in building construction, stair treads are mostly precast stair components cast using molds. Different specifications of precast stair components are required depending on the usage environment, such as different tread heights, widths, and stair component widths. Therefore, different specifications of stair treads need to be cast. Current stair tread casting molds have relatively limited functionality and several problems: demolding is time-consuming and labor-intensive; tread heights, widths, and slab thicknesses are not adjustable; they lack landings, or the thickness of the landings and slab widths are not adjustable. Consequently, stair tread casting molds have low adaptability, requiring molds to be specifically made for only one type of staircase, resulting in wasted casting molds. Summary of the Invention

[0003] This invention provides an integrated casting mold for stair treads, which solves the problems of limited adjustable parameters and low adaptability of stair tread casting molds.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A stair tread integrated casting mold includes an assembly base, a tread bottom mold, an adjustable tread module, a mold release drive device, and an inclined hydraulic cylinder. The tread bottom mold is arranged vertically, and its lower end is detachably connected to the assembly base. One end of the mold release drive device is detachably connected to the adjustable tread module, and the other end is hinged to the assembly base. The mold release drive device is used to drive the adjustable tread module to move towards or away from the tread bottom mold. The adjustable tread module and the tread bottom mold form a tread casting cavity with its upper end in an open state. One end of the inclined hydraulic cylinder is hinged to the assembly base, and the other end is hinged to the lower end of the mold release drive device.

[0006] Furthermore, the adjustable step module includes a plurality of step components arranged sequentially. Each step component includes a step template and a fixing base. The step template and the fixing base are detachably connected. The step template includes a horizontal plate template and a vertical plate template connected vertically. Several slots are spaced apart on the vertical plate template along its length direction, and each slot extends vertically. The horizontal plate template of the step template abuts against the vertical plate template of the adjacent step template, and the two are detachably connected by connecting bolts passing through the slots.

[0007] Furthermore, n width adjustment strips are installed between the horizontal and vertical molds of two adjacent step templates, where n ≥ 1 and n is an integer.

[0008] Furthermore, a translation component parallel to the adjustable step module is fixed above the mold release drive device. The translation component includes a first guide rail and a second guide rail, both of which extend in a direction parallel to the bottom mold of the step. At least one pair of roller sets is provided at the end of each fixed seat that contacts the first guide rail. When there are multiple pairs of roller sets, these pairs of roller sets are spaced apart along the length direction of the first guide rail. Each roller set includes two roller bodies arranged vertically. The first guide rail is located between the two roller bodies, and the two roller bodies roll on the two opposite end faces of the first guide rail. A transverse roller is provided at the end of each fixed seat that contacts the second guide rail, and the transverse roller rolls on the end face of the second guide rail.

[0009] Furthermore, an upper rest platform module is provided at one end of the adjustable step module, and the upper rest platform module has an upper rest platform pouring cavity that is connected to the step pouring cavity.

[0010] Furthermore, the upper rest platform module includes an upper rest platform flat mold, an upper rest platform bottom mold, and a hinge bolt. The upper rest platform casting cavity is formed between the upper rest platform flat mold and the upper rest platform bottom mold, which are arranged opposite to each other. The upper end of the upper rest platform casting cavity is in an open state. The upper rest platform flat mold is detachably connected to one end of the adjustable step module, and the upper rest platform bottom mold is hinged to one end of the step bottom mold. One end of the hinge bolt is detachably connected to the lower end face of the upper rest platform bottom mold, and the other end is detachably connected to the mounting base.

[0011] Furthermore, a lower rest platform module is provided at the other end of the adjustable step module, and the lower rest platform module has a lower rest platform pouring cavity that is connected to the step pouring cavity.

[0012] Furthermore, the lower rest platform module includes a lower rest platform flat mold, a lower rest platform bottom mold, an adjustable tie rod, and a support bolt. The lower rest platform casting cavity is formed between the lower rest platform flat mold and the lower rest platform bottom mold, which are arranged opposite to each other, and the upper end of the lower rest platform casting cavity is in an open state. The lower rest platform flat mold is detachably connected to the other end of the adjustable step module, and the lower rest platform bottom mold abuts against the other end of the step bottom mold. One end of the adjustable tie rod is detachably connected to the lower rest platform bottom mold, and the other end is detachably connected to the step bottom mold. One end of the support bolt is detachably connected to the step bottom mold, and the other end is detachably connected to the lower end face of the lower rest platform bottom mold.

[0013] Furthermore, the mold release drive device includes a movable base, a linear cylinder, and a traveling unit. One end of the movable base is hinged to the upper end face of the assembly seat. Both ends of the inclined cylinder are respectively hinged to the assembly seat and the movable base. The traveling unit is disposed on the upper end face of the movable base. One end of the linear cylinder is connected to the movable base, and the other end is hinged to the traveling unit.

[0014] Furthermore, the walking unit includes two transmission components respectively mounted on both sides of the upper end of the movable base. The transmission components include gears, racks, guide rails, and walking components. The gears and racks mesh with each other, and the guide rails are connected to the walking components. The gears are welded to the walking components via flange shafts. The walking components include front and rear rollers. A locking bolt is installed at one end of the rear roller. The locking bolt passes through the movable base and extends along the mold release direction, and abuts against the rear roller. The two gears are fixedly connected via synchronous shafts.

[0015] The present invention, by employing the aforementioned structure, achieves the following technological advancements compared to existing technologies: When the parameters of the adjustable step module are modified, the inclined hydraulic cylinder extends obliquely, thereby driving the mold release drive device to rotate clockwise by a certain angle around the hinge between the mold release drive device and the mounting base. This causes the adjustable step module to separate from the step bottom mold, completing the demolding action. Then, the parameters of the adjustable step module are modified, followed by the mold closing action. The use of the inclined hydraulic cylinder and the mold release drive device makes mold release and closing more time-saving and labor-saving; the adjustable step module design expands the mold's adaptability; and the universal step bottom mold improves the mold's reusability.

Detailed Implementation

[0038] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0039] This invention discloses an integrated casting mold for stair treads, such as... Figure 1-19As shown, the system includes an assembly base 1, a step bottom mold 28, an adjustable step module 30, a mold release drive device, and an inclined hydraulic cylinder 3. The step bottom mold 28 is arranged vertically, and its lower end is detachably connected to the assembly base 1. One end of the mold release drive device is detachably connected to the adjustable step module 30, and the other end of the mold release drive device is hinged to the assembly base 1. The mold release drive device is used to drive the adjustable step module 30 to move toward or away from the step bottom mold 28. The adjustable step module 30 and the step bottom mold 28 form a step casting cavity 29 with its upper end in an open state. One end of the inclined hydraulic cylinder 3 is hinged to the assembly base 1, and the other end of the inclined hydraulic cylinder 3 is hinged to the lower end of the mold release drive device. The working principle and technological advancements of this invention are as follows: In actual use, the inclined hydraulic cylinder 3 extends obliquely, thereby driving the mold-separating drive device to rotate clockwise by a certain angle around the hinge between the mold-separating drive device and the mounting base 1, causing the adjustable step module 30 to separate from the step bottom mold 28. The parameters of the adjustable step module 30 are modified according to actual requirements, and then the inclined hydraulic cylinder 3 is controlled to reset, completing the mold-closing action. The stair reinforcement frame is then placed into the step pouring cavity 29, and concrete is poured into the step pouring cavity 29 to complete the pouring. Simultaneously, according to actual needs, different amounts of concrete can be poured to different heights, thus realizing the function of pouring precast stair step slabs of different widths. When it is necessary to remove the precast stair step slab, the inclined hydraulic cylinder 3 drives the adjustable step module 30 to separate from the step bottom mold 28, and then the mold-separating drive device separates the adjustable step module 30 from the step bottom mold 28 by a greater distance to facilitate the removal of the precast stair step slab. The use of the inclined hydraulic cylinder 3 and the mold release drive device makes mold release more time-saving and labor-saving; the adjustable step module 30 makes the mold involved in this invention more adaptable; the step bottom mold 28 is universal, which improves the reusability of the mold involved in this invention; by controlling the amount of concrete poured, the function of pouring precast stair step slabs of different widths is realized.

[0040] As a preferred embodiment of the present invention, such as Figure 2 , Figure 13 and Figure 17As shown, the adjustable step module 30 includes multiple step components arranged sequentially. Each step component includes a step template and a fixing base 15. The step template and the fixing base 15 are detachably connected. The step template includes a horizontal plate mold and a vertical plate mold connected vertically. Several slots 56 are spaced apart along the length of the vertical plate mold, each slot 56 extending vertically. The horizontal plate mold of the step template abuts against the vertical plate mold of the adjacent step template, and the two are detachably connected by adjusting bolts 57 passing through the slots 56. The working principle and advantages of this invention are: when the step height is adjusted according to actual needs, in the demolded state, the adjusting bolts 57 are loosened, and the position of the vertical plate mold of the step template is adjusted along the opening direction of the slots 56, thereby adjusting the step height. This design allows for adjustable step height, making the invention more widely applicable.

[0041] As a preferred embodiment of the present invention, such as Figure 18 As shown, the adjustable range of the step height is controlled between 150mm and 200mm. Based on the actual needs of the staircase step height during construction, the step height can be adjusted without steps within the range of 150mm to 200mm.

[0042] As a preferred embodiment of the present invention, such as Figure 18 , 19 As shown, n width adjustment strips 18 are installed between the horizontal and vertical mold plates of two adjacent step templates, where n ≥ 1 and n is an integer. The advantage of this invention is that the width adjustment strips 18 are installed between two adjacent step templates and fixed between them by adjusting bolts 57. The specific number of strips can be selected according to actual needs. Since the thickness of the width adjustment strips 18 is constant, this achieves stepped adjustment of the step width.

[0043] As a preferred embodiment of the present invention, such as Figure 19 As shown, the thickness of the width adjustment strip 18 is 10 mm. The advantage of this invention is that, according to the specific needs of staircase construction, the range of width adjustment will not be too large. Therefore, the thickness of the width adjustment strip 18 is designed to be 10 mm. By adjusting the number of width adjustment strips 18, the step width can be adjusted in stages, with an adjustment range between 240 mm and 300 mm.

[0044] As a preferred embodiment of the present invention, such as Figure 14 , 16As shown, a translation component parallel to the adjustable step module 30 is fixed above the mold release drive device. The translation component includes a first guide rail 13 and a second guide rail 12. Both the first guide rail 13 and the second guide rail 12 extend in a direction parallel to the bottom mold 28 of the step. At least one pair of roller groups 50 is provided at the end of each fixed seat 15 that contacts the first guide rail 13. When there are multiple pairs of roller groups 50, these pairs of roller groups 50 are spaced apart along the length direction of the first guide rail 13. Each roller group 50 includes two roller bodies arranged vertically. The first guide rail 13 is located between the two roller bodies, and the two roller bodies roll on the two opposite end faces of the first guide rail 13. A transverse roller 52 is provided at the end of each fixed seat 15 that contacts the second guide rail 12. The transverse roller 52 rolls on the end face of the second guide rail 12. The working principle of this invention is as follows: In the demolded state, the fixed base 15 connected to the adjustable step module 30 is constrained between the first guide rail 13 and the second guide rail 12. Due to the joint constraint of the first guide rail 13 and the second guide rail 12, the fixed base 15 can be stably constrained between the first guide rail 13 and the second guide rail 12. By increasing the number of roller sets 50 in contact with the first guide rail 13, the stability of the fixed base 15 is improved. Under the action of external force, the fixed base 15 and the connected adjustable step module 30 can move along the direction of the first guide rail 13 and the second guide rail 12 towards both ends of the first guide rail 13 and the second guide rail 12. The advantage of this invention is that it realizes the translation function of the adjustable step module.

[0045] As a preferred embodiment of the present invention, such as Figure 2 , 6 As shown, an upper rest platform module 17 is provided at one end of the adjustable step module 30. The upper rest platform module 17 has an upper rest platform casting cavity 48 that communicates with the step casting cavity 29. The advantage of this invention is that, since the upper rest platform casting cavity 48 and the step casting cavity 29 are connected, the stair steps and the upper rest platform can be cast integrally during the actual casting process, reducing workload and improving work efficiency. At the same time, since the steps and the upper rest platform can be cast integrally rather than separately, the stability of the connection between the stair steps and the upper rest platform is increased.

[0046] As a preferred embodiment of the present invention, such as Figure 6As shown, the upper rest platform module 17 includes an upper rest platform flat mold 33, an upper rest platform bottom mold 32, and a hinge bolt 31. The upper rest platform casting cavity 48 is formed between the upper rest platform flat mold 33 and the upper rest platform bottom mold 32, which are arranged opposite to each other. The upper end of the upper rest platform casting cavity 48 is in an open state. The upper rest platform flat mold 33 is detachably connected to one end of the adjustable step module 30. The upper rest platform bottom mold 32 is hinged to one end of the step bottom mold 28. One end of the hinge bolt 31 is detachably connected to the lower end face of the upper rest platform bottom mold 32, and the other end is detachably connected to the mounting base 1. The working principle and advantages of this invention are as follows: When the adjustable step module 30 moves along the first guide rail 13 and the second guide rail 12 under the action of external force, the upper rest platform flat mold 33 and the adjustable step module 30 are detachably connected, so the upper rest platform flat mold 33 also moves; at the same time, since the upper rest platform bottom mold 32 is hinged to the step bottom mold 28, the pitch angle of the upper rest platform bottom mold 32 can be adjusted, and then the upper rest platform bottom mold 32 is fixed by the hinge bolt 31, and then the upper rest platform module 17 is locked by the T bolt, thereby realizing the adjustment of the thickness of the upper rest platform casting cavity 48, and thus realizing the thickness adjustment of the upper rest platform.

[0047] As a preferred embodiment of the present invention, such as Figure 2 , Figure 7 As shown, a lower rest platform module 16 is provided at the other end of the adjustable step module 30. The lower rest platform module 16 has a lower rest platform casting cavity 47 that communicates with the step casting cavity 29. The advantage of this invention is that, since the lower rest platform casting cavity 47 and the step casting cavity 29 are connected, the stair steps and the lower rest platform can be cast as a single unit during the actual casting process, reducing workload and improving work efficiency. At the same time, since the steps and the lower rest platform can be cast as a single unit rather than being connected separately, the stability of the connection between the stair steps and the lower rest platform is increased.

[0048] As a preferred embodiment of the present invention, such as Figure 7As shown, the lower rest platform module 16 includes a lower rest platform flat mold 25, a lower rest platform bottom mold 26, an adjustable tie rod 27, and a support bolt 37. The lower rest platform casting cavity 47 is formed between the lower rest platform flat mold 25 and the lower rest platform bottom mold 26, which are arranged opposite to each other. The upper end of the lower rest platform casting cavity 47 is in an open state. The lower rest platform flat mold 25 is detachably connected to the other end of the adjustable step module 30. The lower rest platform bottom mold 26 abuts against the other end of the step bottom mold 28. One end of the adjustable tie rod 27 is detachably connected to the lower rest platform bottom mold 26, and the other end is detachably connected to the step bottom mold 28. One end of the support bolt 37 is detachably connected to the step bottom mold 28, and the other end is detachably connected to the lower end face of the lower rest platform bottom mold 26. The working principle and advantages of this invention are as follows: When the adjustable step module 30 moves along the first guide rail 13 and the second guide rail 12 under the action of external force, after the thickness of the upper rest platform is adjusted and locked, the lower rest platform flat mold 25 and the adjustable step module 30 are detachably connected, so the lower rest platform flat mold 25 also moves; at the same time, since the lower rest platform bottom mold 26 abuts against the step bottom mold 28, and the support bolt 37 is detachably connected to the step bottom mold 28, the pitch angle and position of the lower rest platform bottom mold 26 can be adjusted by adjusting the adjustable tie rod 27 and the support bolt 37, and then the lower rest platform module 16 is locked by the T-bolt, thereby realizing the adjustment of the thickness of the lower rest platform casting cavity 47, and thus realizing the thickness adjustment of the lower rest platform.

[0049] As a preferred embodiment of the present invention, such as Figure 1 , 4 As shown, the mold release and closing drive device includes a movable base 2, a linear hydraulic cylinder 6, and a traveling unit. One end of the movable base 2 is hinged to the upper surface of the mounting base 1. Both ends of the inclined hydraulic cylinder 3 are hinged to the mounting base 1 and the movable base 2, respectively. The traveling unit is disposed on the upper surface of the movable base 2. One end of the linear hydraulic cylinder 6 is connected to the movable base 2, and the other end is hinged to the traveling unit. The working principle and advantages of this invention are: during the mold release and closing process, the linear hydraulic cylinder 6 drives the traveling unit to move, thereby causing the adjustable step module 30 to move away from or towards the step bottom mold 28, making the entire mold release and closing process more time-saving and labor-saving.

[0050] As a preferred embodiment of the present invention, such as Figure 4 , 5As shown in Figures 9, 10, and 11, the walking unit includes two transmission components respectively mounted on both sides of the upper end of the movable base 2. The transmission components include a gear 10, a rack 5, a guide rail 4, and a walking component 7. The gear 10 and the rack 5 mesh with each other, and the guide rail 4 is connected to the walking component 7. The gear 10 and the walking component 7 are welded together via a flange shaft. The walking component 7 includes a front ground roller 8 and a rear ground roller 9. A locking bolt 11 is installed at one end of the rear ground roller. The locking bolt 11 passes through the movable base 2 and extends along the mold release direction, and abuts against the rear ground roller. The two gears 10 are fixedly connected by a synchronous shaft 46. The working principle and advantages of this invention are as follows: When the linear cylinder 6 moves, the gear 10 in the transmission assembly moves on the rack 5, and the walking assembly 7 moves on the guide rail 4. At the same time, since the gear 10 and the walking assembly 7 are welded together through the flange shaft, the consistency of movement between the transmission assembly and the walking assembly 7 is ensured. Meanwhile, the two gears 10 are fixedly connected through the synchronous shaft 46, which further ensures the consistency of movement between the transmission assembly and the walking assembly 7 mounted on both sides of the upper end of the movable base 2. This makes the movement of the entire mold release drive device more stable and coordinated, and realizes the stability and accuracy of the adjustable step module 30. Since a locking bolt 11 is installed at one end of the rear roller of the walking assembly 7, the locking bolt 11 passes through the movable base 2 and extends along the mold release direction. When the mold release drive device moves to a certain position, the distance between the adjustable step module 30 and the step bottom mold 28 changes. At this time, the locking bolt 11 is pressed against the rear roller to fix it in this position, so that the thickness of the stair tread changes, realizing the function of stepless adjustment of the thickness of the stair tread.

[0051] As a preferred embodiment of the present invention, the thickness of the stair tread can be adjusted from 90mm to 190mm, depending on the specific construction requirements of the stair tread.

[0052] As a preferred embodiment of the present invention, such as Figure 9 , 12 As shown, anti-tilt components 42 are installed on the walking components 7 located on both sides of the upper surface of the movable base 2. Limiting rollers 55, which contact the two sides of the guide rail 4, are respectively installed on the two opposite inner surfaces of the anti-tilt components 42. Fastening bolts 58 are installed vertically downwards at the upper end of the anti-tilt components 42. The working principle and advantages of this invention are as follows: the limiting rollers 55, which contact the two sides of the guide rail 4, restrict the walking components 7 to the guide rail 4. The fastening bolts 58 at the upper end of the anti-tilt components 42 fix the anti-tilt components 42 to the walking components 7. The anti-tilt components 42 can move together with the walking components 7, preventing the adjustable step module 30, which is fixedly installed on the walking components 7, from detaching from the guide rail 4 under unstable external forces, thus preventing damage to the adjustable step module 30.

[0053] As a preferred embodiment of the present invention, such as Figure 2As shown, a similarly structured walking component 7 is positioned between the two walking components 7 located on either side of the upper surface of the movable base 2, in a direction away from the adjustable step module 30, with a matching guide rail below it. This arrangement allows the adjustable step module 30 to move more stably on the movable base 2.

[0054] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
