Description

Technical Field

[0001] This invention relates to aluminum alloy staircase formwork technology, specifically to a prefabricated aluminum alloy staircase formwork. Background Technology

[0002] Currently, staircases in buildings are generally made of concrete or brick. Brick and stone construction requires more manpower and takes longer than concrete construction, so concrete staircases are widely used in existing technologies.

[0003] Chinese utility model patent CN202882417U discloses a stair template structure, including a stair side template and a step template. The top of the stair side template is provided with evenly distributed limiting grooves, each limiting groove including a bottom wall and a front wall and a rear wall fixed to the top of the bottom wall. The stair template structure also includes a positioning block and an axe tip set in the limiting groove. The side of the step template near the front wall abuts against the front wall, and the side of the step template away from the front wall abuts against the inner side wall of the positioning block. The end of the axe tip near the rear wall abuts against the rear wall, and the end of the axe tip away from the rear wall abuts against the outer side wall of the positioning block. This makes the installation of stair step templates toolable and standardized, saves materials, and can also effectively improve work efficiency.

[0004] However, the aforementioned stair formwork is an integral structure, so its overall structure is relatively large. In practical applications, an excessively large stair formwork will not only be easily obstructed during transportation, but will also increase the difficulty of construction and hinder the stair pouring and construction work. Summary of the Invention

[0005] The purpose of this invention is to provide a prefabricated aluminum alloy staircase formwork to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated aluminum alloy staircase template, comprising an inclined plate, a template mechanism being provided at the top of the inclined plate, the template mechanism comprising several sets of side plates distributed sequentially from bottom to top, and each set of side plates comprising two side plates symmetrically distributed on both sides of the inclined plate, an embedded strip being fixedly connected to one side of each pair of side plates facing each other, a bottom mold being provided between two adjacent side plates on the same horizontal plane, a connecting mold being provided between two adjacent side plates on the same horizontal plane, a top mold being provided at the top of the inclined plate, a feeding port being provided on the side of the top mold, a feeding port being formed between the top of the contact surface between the connecting mold and the inclined plate and between the top of the contact surface between the bottom mold and the inclined plate, a discharge port being formed between the bottom of the contact surface between the connecting mold and the inclined plate and between the bottom of the contact surface between the top mold and the inclined plate, and connecting grooves being provided on both sides of the bottom mold and both sides of the connecting mold;

[0007] A fixing mechanism is used to fix the side plate to the inclined plate, or to fix the top mold to the inclined plate.

[0008] Furthermore, the bottom mold is set at the bottom of the inclined plate surface, and the top mold is set at the top of the inclined plate. The bottom surface of the bottom mold abuts against the upper surface of the inclined plate. After installation, the bottom surface of the bottom mold is in a tight abutment with the upper surface of the inclined plate, which makes the contact sealing between the bottom mold and the inclined plate good, so that there will be no grout leakage during the grouting process.

[0009] Furthermore, both the bottom mold and the connecting mold are right-angled, and the shape and size of the connecting groove are adapted to the embedded strip.

[0010] Furthermore, the fixing mechanism includes an extension groove on the inner side of the side plate. A T-shaped plate is slidably connected to the inner side of the extension groove, and an L-shaped plate is fixedly connected to the outer side of the T-shaped plate. Two symmetrically distributed adjusting screws are threadedly connected to the transverse bottom surface of the L-shaped plate. The ends of the two adjusting screws are fixedly and rotatably connected to the same pressure plate. A threaded groove is provided on the transverse bottom surface of the L-shaped plate. The adjusting screws are threadedly connected to the threaded groove, so that during the rotation of the adjusting screws, under the action of the threaded groove, the adjusting screws can drive the pressure plate to slide along the longitudinal plane of the L-shaped plate, thereby moving it to contact and press against the bottom surface of the inclined plate. With the cooperation of the side plate, the side plate and the inclined plate can be stably connected. The movable stroke value of the T-shaped plate inside the extension groove is greater than the horizontal width value of the L-shaped plate, so that when the side plate is placed, the L-shaped plate can be pulled away from the side plate, so that its bottom is completely removed from the coverage area of ​​the inclined plate, and it will not obstruct the normal installation of the side plate.

[0011] Furthermore, the longitudinal section shape of the extension groove and the longitudinal section shape of the T-shaped plate are both T-shaped, and the size and specifications of the extension groove are adapted to the T-shaped plate. The side of the T-shaped plate is in a close fit with the inner wall of the extension groove, which makes the sliding stability of the T-shaped plate better when sliding along the inner wall of the extension groove, and when fixing the side plate, the side plate and the inclined plate can be fixed more firmly.

[0012] Furthermore, the bottom mold and the connecting mold are provided with a reinforcement mechanism on their exterior. The reinforcement mechanism includes a reinforcement groove formed on the top surface of the bottom mold and the connecting mold, and reinforcement plates are formed on the sides of the connecting mold and the top mold.

[0013] Furthermore, the reinforcing plate is right-angled, and the shape, size, and specifications of the vertical section of the reinforcing plate are adapted to the reinforcing groove. When the reinforcing plate is embedded in the reinforcing groove, the inner wall of the reinforcing groove is fully in contact with the surface of the reinforcing plate, so that the reinforcing groove can effectively restrict the movement of the reinforcing plate. Thus, after the reinforcing plate is embedded in the reinforcing groove, the horizontal connection stability between the upper and lower connecting molds, or between the connecting mold and the bottom mold, or between the connecting mold and the top mold is better.

[0014] Furthermore, the top mold is provided with a pushing mechanism, which includes guide grooves symmetrically opened on both sides of the inner wall of the top mold. The inner side of the guide groove is slidably connected to a sliding plate. A pushing plate is fixedly connected between the two sliding plates. The surface of the pushing plate is provided with a plurality of exhaust holes distributed in an array. Support columns are fixedly connected to the opposing side surfaces of the two sliding plates. A slot is opened on the side of the top mold away from the feeding port. A support rod is fixedly connected to the inner side of the slot. A U-shaped rod is slidably connected to the outside of the support rod. Sliding grooves are opened on both sides of the U-shaped rod near the opening.

[0015] Furthermore, the support column and the support rod are slidably connected on the inner side of the sliding groove. The support rod serves as a fixed fulcrum for the rotation of the U-shaped rod. Under the guidance of the guide groove, the support column can be moved vertically by rotating the U-shaped rod in conjunction with the sliding groove. When the support column moves vertically, it will drive the push plate to move vertically, so that the push plate can move downward as needed to push the slurry inside the top mold downward, making the slurry filling in the grouting space formed between the template mechanism and the inclined plate more compact.

[0016] Compared with the prior art, the prefabricated aluminum alloy stair formwork provided by the present invention has the following beneficial effects:

[0017] 1. This prefabricated aluminum alloy stair formwork, through the cooperation between side plates, bottom mold, connecting mold, top mold, embedded strips and connecting grooves, can be assembled into a complete stair mold during the cement pouring process. Moreover, the overall structural size of all the units that make up the stair mold is small, making it more convenient to handle, assemble and disassemble.

[0018] 2. This prefabricated aluminum alloy stair formwork, through the use of a fixing mechanism, can stably fix the stair formwork to the inclined plate after assembly, and the fixing process is simpler and faster, without the need to carry additional fixing parts, making the assembly and fixing process of the formwork more convenient.

[0019] 3. The prefabricated aluminum alloy stair formwork, through the use of reinforcement mechanisms, improves the horizontal connection stability between adjacent connecting molds, between connecting molds and bottom molds, and between connecting molds and top molds. Therefore, when pouring staircases in different scenarios, the number of side plates on the same horizontal plane can be selected according to actual needs, so as to meet the construction needs in cases where there are walls on the sides or not. This makes the assembly flexibility of the formwork better, while maintaining good working stability.

[0020] 4. This prefabricated aluminum alloy staircase formwork, through the use of a pushing mechanism, can push the cement slurry located at a high position downwards according to actual needs during the cement pouring process, so that the cement slurry inside the bottom cavity is filled more compactly, thereby resulting in better quality of the poured staircase.

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1:

[0033] Please see Figures 1-5 A prefabricated aluminum alloy stair template includes an inclined plate 1. A template mechanism 2 is provided on the top of the inclined plate 1. The template mechanism 2 includes several sets of side plates 21 distributed sequentially from bottom to top. Each set of side plates 21 includes two side plates 21 symmetrically distributed on both sides of the inclined plate 1. An embedded strip 22 is fixedly connected to the opposite side of the two side plates 21 in each set. A bottom mold 23 is provided between two adjacent side plates 21 on the same horizontal plane. A connecting mold 24 is provided between two adjacent side plates 21 on the same horizontal plane. A top mold 25 is provided on the top of the inclined plate 1. A feeding port 29 is opened on the side of the top mold 25. A feeding port 26 is formed between the top of the contact surface between the connecting mold 24 and the inclined plate 1 and between the top of the contact surface between the bottom mold 23 and the inclined plate 1. A discharge port 27 is formed between the bottom of the bottom mold 24 and the bottom of the contact surface between the top mold 25 and the inclined plate 1. A connecting groove 28 is opened on both sides of the bottom mold 23 and both sides of the connecting mold 24.

[0034] The fixing mechanism 3 is used to fix the side plate 21 to the inclined plate 1, or to fix the top mold 25 to the inclined plate 1.

[0035] In this embodiment, the bottom mold 23 is disposed at the bottom of the surface of the inclined plate 1, the top mold 25 is disposed at the top of the inclined plate 1, and the bottom surface of the bottom mold 23 abuts against the upper surface of the inclined plate 1.

[0036] Specifically, after installation, the bottom surface of the bottom mold 23 is in close contact with the upper surface of the inclined plate 1, which ensures good sealing between the bottom mold 23 and the inclined plate 1, so that no grout leakage will occur during the grouting process.

[0037] In this embodiment, the bottom mold 23 and the connecting mold 24 are both right-angled, and the shape and size of the connecting groove 28 are adapted to the embedded strip 22.

[0038] In this embodiment, the fixing mechanism 3 includes an extension groove 31 formed on the inner side of the side plate 21. A T-shaped plate 32 is slidably connected to the inner side of the extension groove 31. An L-shaped plate 33 is fixedly connected to the outer side of the T-shaped plate 32. Two symmetrically distributed adjusting screws 34 are threadedly connected to the transverse bottom surface of the L-shaped plate 33. The ends of the two adjusting screws 34 are fixedly and rotatably connected to the same pressure plate 35.

[0039] Specifically, the horizontal bottom surface of the L-shaped plate 33 is provided with a threaded groove. The adjusting screw 34 is threadedly connected to the threaded groove, so that when the adjusting screw 34 rotates, under the action of the threaded groove, the adjusting screw 34 can drive the pressure plate 35 to slide along the longitudinal plane of the L-shaped plate 33, thereby moving to contact and press with the bottom surface of the inclined plate 1, so that under the action of the side plate 21, the side plate 21 and the inclined plate 1 can be stably connected.

[0040] It should be further explained that the movable stroke value of the T-shaped plate 32 inside the extension groove 31 is greater than the horizontal width value of the L-shaped plate 33, so that when the side plate 21 is placed, the L-shaped plate 33 can be pulled away from the side plate 21, so that its bottom is completely removed from the coverage of the inclined plate 1, so that it will not obstruct the normal installation of the side plate 21.

[0041] In this embodiment, the longitudinal section shape of the extension groove 31 and the longitudinal section shape of the T-shaped plate 32 are both T-shaped, and the size and specifications of the extension groove 31 are adapted to the T-shaped plate 32.

[0042] Specifically, the side of the T-shaped plate 32 is in contact with the inner wall of the extension groove 31, which makes the sliding stability of the T-shaped plate 32 better when sliding along the inner wall of the extension groove 31, and when fixing the side plate 21, the side plate 21 can be fixed more firmly to the inclined plate 1.

[0043] Example 2:

[0044] Please see Figure 3 and Figure 4 This embodiment provides a technical solution based on embodiment one: a reinforcing mechanism 4 is provided on the outside of the bottom mold 23 and the connecting mold 24. The reinforcing mechanism 4 includes a reinforcing groove 41 opened on the top surface of the bottom mold 23 and the connecting mold 24, and a reinforcing plate 42 is opened on the side of the connecting mold 24 and the top mold 25.

[0045] In this embodiment, the reinforcing plate 42 is right-angled, and the shape, size, and specifications of the vertical section of the reinforcing plate 42 are adapted to the reinforcing groove 41.

[0046] Specifically, when the reinforcing plate 42 is embedded inside the reinforcing groove 41, the inner wall of the reinforcing groove 41 is fully in contact with the surface of the reinforcing plate 42, so that the reinforcing groove 41 can effectively restrict the movement of the reinforcing plate 42. Thus, after the reinforcing plate 42 is embedded inside the reinforcing groove 41, the horizontal connection stability between the upper and lower connecting molds 24, or between the connecting mold 24 and the bottom mold 23, or between the connecting mold 24 and the top mold 25 is better.

[0047] Example 3:

[0048] Please see Figures 1-7 This embodiment provides a technical solution based on Embodiments 1 and 2: a prefabricated aluminum alloy staircase template, including an inclined plate 1, a template mechanism 2 at the top of the inclined plate 1, the template mechanism 2 including several sets of side plates 21 distributed sequentially from bottom to top, and each set of side plates 21 including two side plates 21 symmetrically distributed on both sides of the inclined plate 1, an embedded strip 22 fixedly connected to the opposite side of the two side plates 21 in each set, a bottom mold 23 between two adjacent side plates 21 on the same horizontal plane, and a connecting mold between two adjacent side plates 21 on the same horizontal plane. 24. A top mold 25 is provided on the top of the inclined plate 1. A feeding port 29 is provided on the side of the top mold 25. Feed ports 26 are formed between the top of the contact surface between the connecting mold 24 and the inclined plate 1 and between the top of the contact surface between the bottom mold 23 and the inclined plate 1. Discharge ports 27 are formed between the bottom of the contact surface between the connecting mold 24 and the inclined plate 1 and between the bottom of the top mold 25 and the inclined plate 1. Connecting grooves 28 are provided on both sides of the bottom mold 23 and both sides of the connecting mold 24. A fixing mechanism 3 is used to fix the side plate 21 to the inclined plate 1 or to fix the top mold 25 to the inclined plate 1.

[0049] In this embodiment, the bottom mold 23 is disposed at the bottom of the surface of the inclined plate 1, the top mold 25 is disposed at the top of the inclined plate 1, and the bottom surface of the bottom mold 23 abuts against the upper surface of the inclined plate 1.

[0050] Specifically, after installation, the bottom surface of the bottom mold 23 is in close contact with the upper surface of the inclined plate 1, which ensures good sealing between the bottom mold 23 and the inclined plate 1, so that no grout leakage will occur during the grouting process.

[0051] In this embodiment, the bottom mold 23 and the connecting mold 24 are both right-angled, and the shape and size of the connecting groove 28 are adapted to the embedded strip 22.

[0052] In this embodiment, the fixing mechanism 3 includes an extension groove 31 formed on the inner side of the side plate 21. A T-shaped plate 32 is slidably connected to the inner side of the extension groove 31. An L-shaped plate 33 is fixedly connected to the outer side of the T-shaped plate 32. Two symmetrically distributed adjusting screws 34 are threadedly connected to the transverse bottom surface of the L-shaped plate 33. The ends of the two adjusting screws 34 are fixedly and rotatably connected to the same pressure plate 35.

[0053] Specifically, the horizontal bottom surface of the L-shaped plate 33 is provided with a threaded groove. The adjusting screw 34 is threadedly connected to the threaded groove, so that when the adjusting screw 34 rotates, under the action of the threaded groove, the adjusting screw 34 can drive the pressure plate 35 to slide along the longitudinal plane of the L-shaped plate 33, thereby moving to contact and press with the bottom surface of the inclined plate 1, so that under the action of the side plate 21, the side plate 21 and the inclined plate 1 can be stably connected.

[0054] It should be further explained that the movable stroke value of the T-shaped plate 32 inside the extension groove 31 is greater than the horizontal width value of the L-shaped plate 33, so that when the side plate 21 is placed, the L-shaped plate 33 can be pulled away from the side plate 21, so that its bottom is completely removed from the coverage of the inclined plate 1, so that it will not obstruct the normal installation of the side plate 21.

[0055] In this embodiment, the longitudinal section shape of the extension groove 31 and the longitudinal section shape of the T-shaped plate 32 are both T-shaped, and the size and specifications of the extension groove 31 are adapted to the T-shaped plate 32.

[0056] Specifically, the side of the T-shaped plate 32 is in contact with the inner wall of the extension groove 31, which makes the sliding stability of the T-shaped plate 32 better when sliding along the inner wall of the extension groove 31. When fixing the side plate 21, the side plate 21 and the inclined plate 1 can be fixed more firmly. The bottom mold 23 and the connecting mold 24 are provided with a reinforcement mechanism 4. The reinforcement mechanism 4 includes a reinforcement groove 41 opened on the top surface of the bottom mold 23 and the connecting mold 24. The sides of the connecting mold 24 and the top mold 25 are provided with reinforcement plates 42.

[0057] In this embodiment, the reinforcing plate 42 is right-angled, and the shape, size, and specifications of the vertical section of the reinforcing plate 42 are adapted to the reinforcing groove 41.

[0058] Specifically, when the reinforcing plate 42 is embedded inside the reinforcing groove 41, the inner wall of the reinforcing groove 41 is fully fitted with the surface of the reinforcing plate 42, so that the reinforcing groove 41 can effectively restrict the movement of the reinforcing plate 42. Therefore, after the reinforcing plate 42 is embedded inside the reinforcing groove 41, the horizontal connection stability between the upper and lower connecting molds 24, or between the connecting mold 24 and the bottom mold 23, or between the connecting mold 24 and the top mold 25 is better.

[0059] In this embodiment, a pushing mechanism 5 is provided inside the top mold 25. The pushing mechanism 5 includes guide grooves 51 symmetrically opened on both sides of the inner wall of the top mold 25. The inner side of the guide grooves 51 is slidably connected to the slide plate 52. A pushing plate 53 is fixedly connected between the two slide plates 52. The surface of the pushing plate 53 is provided with a plurality of exhaust holes 54 distributed in an array. Support columns 55 are fixedly connected to the opposing side surfaces of the two slide plates 52. A slot is opened on the side of the top mold 25 away from the feeding port 29. A support rod 56 is fixedly connected to the inner side of the slot. A U-shaped rod 57 is slidably connected to the outside of the support rod 56. Slide grooves 58 are opened on both sides of the U-shaped rod 57 near the opening.

[0060] In this embodiment, the support column 55 and the support rod 56 are slidably connected to the inner side of the groove 58.

[0061] Specifically, the support rod 56 serves as the fixed fulcrum for the rotation of the U-shaped rod 57. Under the guidance of the guide groove 51, the rotation of the U-shaped rod 57 can drive the support column 55 to move vertically with the cooperation of the sliding groove 58. When the support column 55 moves vertically, it will drive the push plate 53 to move vertically, so that the push plate 53 can move downward as needed to push the slurry inside the top mold 25 downward, making the slurry filling in the grouting space formed between the template mechanism 2 and the inclined plate 1 more compact.

[0062] In this embodiment, during installation, the operator places one side plate 21 of the installation base mold 23 at the bottom of the inclined plate 1, then rotates the adjusting screw 34. The adjusting screw 34 rotates and moves upward, driving the pressure plate 35 to move upward until the pressure plate 35 abuts against the bottom surface of the inclined plate 1, thereby fixing the side plate 21 on the inclined plate 1. Then, the base mold 23 is placed on the inclined plate 1, and the embedding strip 22 on its side is embedded into the connecting groove 28 on the fixed side plate 21. Then, the other side plate 21 is fixed in the same way to complete the fixing of the base mold 23.

[0063] After the bottom mold 23 is fixed, the connecting mold 24 is taken out and the reinforcing plate 42 on the connecting mold 24 is inserted into the reinforcing groove 41 on the bottom mold 23. The connecting mold 24 is supported by the cooperation of the reinforcing plate 42 and the reinforcing groove 41. Then, the two side plates 21 are taken out and the connecting grooves 28 on the two side plates 21 are aligned with the embedding strips 22 on the connecting mold 24, so that the embedding strips 22 are inserted into the connecting grooves 28. The side plates 21 are then fixed in the above-mentioned fixing method to complete the fixing of one connecting mold 24.

[0064] The required number of connecting molds 24 are assembled using the method described above;

[0065] When it is necessary to assemble the top mold 25, its external reinforcing plate 42 is inserted into the reinforcing groove 41 on the connecting mold 24, and then it is fixed in the same way to complete the assembly of the casting mold.

[0066] During the pouring process, the operator can rotate the end of the U-shaped rod 57 away from the push plate 53 upwards, so that the end of the rod close to the push plate 53 rotates downwards under the support of the support rod 56. With the cooperation of the slide groove 58, when the end of the U-shaped rod 57 close to the push plate 53 rotates downwards, it will drive the support column 55 to move downwards. The downward movement of the support column 55 will drive the push plate 53 to move downwards, so that the push plate 53 can squeeze the cement slurry inside the top mold 25 downwards, making the cement slurry inside the lower mold more fully and tightly filled, thus resulting in a better quality of the final poured staircase.

[0067] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
