Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a modular template for the concrete treads at the bottom of a steel ladder that is easy to assemble and disassemble. Background Technology

[0002] A steel ladder is a type of staircase made of steel. During installation and use, concrete steps are typically built at the bottom of the steel ladder. The pouring of these concrete steps requires the use of prefabricated formwork. This involves installing the formwork in a predetermined area, then pouring concrete into the inside of the formwork, allowing it to be shaped. Once the concrete has hardened, the concrete steps are formed. However, existing prefabricated formwork is generally composed of individual support panels, which means that each panel needs to be handled separately during assembly and disassembly, making the process cumbersome. Summary of the Invention

[0003] The purpose of this invention is to provide a modular template for the concrete treads at the bottom of a steel ladder that is easy to assemble and disassemble, in order to solve the problem mentioned in the background art that the existing modular templates are generally composed of individual support plates, which leads to the need to process each piece of the modular template individually during the assembly and disassembly process, which is quite troublesome.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] Please see Figure 1 A modular template for the concrete treads at the bottom of a steel ladder, which is easy to assemble and disassemble, includes: a first side panel 1 and a second side panel 2 in a stepped shape, with the first side panel 1 located on the left and the second side panel 2 located on the right; a front panel 3 is hinged to the front side of the first side panel 1 via a rotating assembly 6, and a rear panel 4 is fixedly installed on the rear side of the first side panel 1. The right side of the rear panel 4 is hinged to the rear side of the second side panel 2 via the rotating assembly 6, and the front side of the second side panel 2 is detachably connected to the right side of the front panel 3; a step panel assembly is hinged to the top of the rear panel 4 via the rotating assembly 6. The step panel assembly is stepped and is used to limit the front sidewall of the step between the first side panel 1 and the second side panel 2. The step panel assembly is detachably connected to the front panel 3.

[0026] It should be noted that the first side baffle 1, the second side baffle 2, the front baffle 3, the rear baffle 4, and the step baffle assembly together form a template, all of which can be made of steel.

[0027] It should also be noted that, according to Figure 1As shown, the fixed template in this application is mainly for pouring concrete three-step concrete, but it is not only for concrete three-step concrete; other concrete steps can be poured by changing the shape of the fixed template.

[0028] In this embodiment, as a further optimization, please refer to... Figure 1 The step baffle assembly includes several sets of step baffles 7 arranged in a stepped manner (according to...). Figure 1 As shown, for the pouring of three concrete steps, there are two step baffles 7. The number of step baffles 7 is one less than the number of concrete steps being poured, and they are used to limit the front side of the treads, but do not include the bottom concrete step (i.e., excluding the first step). The step baffles 7 are provided with connectors 8. Adjacent step baffles 7 are connected by connectors 8. The upper step baffle 7 is connected to the rotating assembly 6 by connectors 8, and the lower step baffle 7 is detachably connected to the front baffle 3 by connectors 8. The connectors 8 can be made of steel bars.

[0029] In this embodiment, as a further optimization, please refer to... Figure 1 The front baffle 3 is provided with a third pin cylinder 12, and the front side of the second side baffle 2 is provided with a second pin 13. The second pin 13 is inserted into the third pin cylinder 12 and is used to connect the front side of the second side baffle 2 with the right side of the front baffle 3. When the second pin 13 is removed from the third pin cylinder 12, the connection between the second side baffle 2 and the front baffle 3 is disconnected. The front baffle 3 is provided with a second pin cylinder 10, and the lower connecting member 8 is provided with a first pin cylinder 9. A first pin 11 is inserted between the first pin cylinder 9 and the second pin cylinder 10 and is used to connect the front side of the step baffle assembly with the front baffle 3. When the first pin 11 is removed from the first pin cylinder 9 and the second pin cylinder 10, the connection between the step baffle assembly and the front baffle 3 is disconnected.

[0030] In this embodiment, as a further optimization, please refer to... Figure 1 Both the first pin 11 and the second pin 13 have external threads on their outer walls, and the first pin cylinder 9, the second pin cylinder 10 and the third pin cylinder 12 have internal threads for matching the external threads; these are used to fix the first pin 11 and the second pin 13 so that they will not move easily, and to ensure the stability of the connection between the front baffle 3 and the second side baffle 2 and the step baffle assembly.

[0031] In this embodiment, as a further optimization, please refer to... Figure 1 The outer walls of the first side baffle 1, the second side baffle 2 and the rear baffle 4 are all provided with reinforcing ribs 5; these are used to increase the strength of the first side baffle 1, the second side baffle 2 and the rear baffle 4 and improve the reusability of the molded template.

[0032] Working principle: Before pouring the concrete steps, the formwork is placed in a fixed area. Then, the front baffle 3 is rotated backward and the second side baffle 2 is rotated to the left until they come into contact and are connected. Next, the step baffle assembly is rotated downward and connected to the front baffle 3. After the connection is completed, the formwork is fixed to prevent it from moving automatically. Concrete is poured into the formwork and the concrete is treated (such as leveling; the processing procedure during the concrete step pouring process is not described in detail here, as this method is existing technology). After the pouring is completed, the concrete is allowed to solidify. The connection between the step baffle assembly and the front baffle 3 is disconnected, the step baffle assembly is rotated upward, and the connection between the front baffle 3 and the second side baffle 2 is disconnected. The second side baffle 2 is rotated to the right, and the front baffle 3 is rotated forward. Finally, the entire formwork is moved and removed from the poured concrete steps.

[0033] Example 2

[0034] As a further optimization of Example 1, please refer to Figure 2 The rotating assembly 6 includes a mounting member 61 and a kit 62 rotatably sleeved on the outer wall of the mounting member 61. A torsion spring 63 is sleeved on the outer wall of the mounting member 61, and the two ends of the torsion spring 63 are respectively connected to the inner wall of the kit 62 and the outer wall of the mounting member 61. When the connection between the step baffle assembly and the front baffle 3 is disconnected, the torsion spring 63 of the rotating assembly 6 acts to make the kit 62 rotate on the outer wall of the mounting member 61, so as to make the step baffle assembly rotate upward and automatically lift it up. The torsion spring 63 also provides support for the rotated kit 62. This prevents the step baffle assembly from automatically resetting after rotation, thus preventing it from automatically moving downwards. Similarly, when the connection between the front baffle 3 and the second side baffle 2 is disconnected, the rotating assembly 6 can also rotate and unfold the second side baffle 2 and the front baffle 3, supporting them and preventing them from resetting. This ensures that the front baffle 3, the second side baffle 2, and the step baffle assembly will not touch the concrete steps during the removal of the template, making it easier to disassemble the template without having to support all three.

[0035] In this embodiment, as a further optimization, please refer to... Figure 2The mounting component 61 has a connecting block 65 at one end of the assembly 62. A limiting block 66 is slidably mounted on the connecting block 65. An elastic element (spring) is installed between the connecting block 65 and the limiting block 66. The limiting block 66 moves along the length of the assembly 62. A stop block 64 is provided on the outer circumference of the assembly 62. The end of the stop block 64 is in contact with the end of the limiting block 66 to prevent the limiting block 66 from moving. During the rotation of the assembly 62 with the torsion spring 63, the stop block 64 and the limiting block 66 are misaligned and do not contact each other. Under the action of the elastic element, the limiting block 66 moves, so that the limiting block 66 and the stop block 64 are on the same circular motion trajectory. The presence of the limiting block 66 and the stop block 64 prevents the assembly 62 from rotating and resetting, so that the front baffle 3, the second side baffle 2 and the step baffle assembly will not touch the concrete step during the removal of the molded template, thus avoiding scratching the concrete step and protecting the concrete step.

[0036] In this embodiment, as a further optimization, please refer to... Figure 2 , Figure 3 and Figure 4 The mounting component 61 includes a movable block 611 and a mounting block 613. The movable block 611 is rotatably inserted into the inner cavity of the kit 62. The mounting block 613 has a mounting groove 615 on the side near the movable block 611. The movable block 611 has a moving block 612 on the end away from the kit 62. The moving block 612 is inserted into the inner cavity of the mounting groove 615 (the moving block 612 can slide or rotate in the mounting groove 615). A screw hole is opened in the mounting groove 615. The screw hole is coaxial with the moving block 612. A screw rod 616 for screwing into the screw hole is provided on the inner end of the moving block 612. An elastic element 614 (spring) is provided between the mounting groove 615 and the moving block 612. The mounting component 61 is the mounting component 61 between the first side baffle 1 and the front baffle 3, and between the second side baffle 2 and the rear baffle 4 (that is, the mounting component 61 on the step baffle assembly is not composed of the above structure, but is a separate mounting component 61).

[0037] It should be noted that during the rotation of the front baffle 3 and the second side baffle 2, the movable block 611 is rotated, causing the moving block 612 to rotate along with the screw 616, moving the screw 616 out of the screw hole, and expanding through the elastic element 614, causing the movable block 611 to move upward with the kit 62, raising the height of the front baffle 3 and the second side baffle 2, preventing them from contacting the ground during the unfolding process, facilitating their rotation, and making it easy to remove the shaping template.

[0038] In this embodiment, as a further optimization, please refer to... Figure 4An mounting ring 617 is rotatably mounted on the inner end of the movable block 612, and the elastic element 614 is connected to the mounting ring 617. During the rotation of the movable block 612, the mounting ring 617 can also rotate on the inner end of the movable block 612, so that the elastic element 614 will not be twisted during the rotation of the movable block 612.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
