Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a formwork structure for building staircase construction. Background Technology

[0002] In construction engineering, staircases serve as crucial vertical passages connecting different floors, making their construction quality paramount. Currently, commonly used staircase formwork structures present several problems. Traditional formwork connections are often insufficiently stable. During concrete pouring, the weight and lateral pressure of the concrete cause loosening and deformation at the formwork joints, leading to concrete leakage and affecting the staircase's final shape and appearance. Furthermore, existing formwork support structures are inadequate, failing to effectively distribute the pressure on the formwork, resulting in insufficient stability during construction, increased safety hazards, and reduced construction efficiency. Therefore, a new type of staircase formwork structure needs to be designed to address these issues. Utility Model Content

[0037] like Figures 1-6 As shown, this utility model provides a construction formwork structure for building stairs, which mainly includes a construction base plate 1, a top formwork 2, a stair formwork 3, a reinforcing connection mechanism 4, a protective side plate 5, and a fixed support mechanism 6.

[0038] The upper surface of the construction base slab 1 is sloped to meet the slope requirements of the staircase, facilitating the subsequent pouring and shaping of the staircase. The top formwork 2 is installed on the top surface of the construction base slab 1, and its top is bolted to the upper surface of the construction base slab 1. Several pouring ports 20 are provided on the top formwork 2 for easy concrete injection. Multiple staircase formwork 3s are arranged on the upper surface of the construction base slab 1, connected end-to-end. The top staircase formwork 3 connects to the top formwork 2, and the bottom staircase formwork 3 connects to the bottom of the construction base slab 1, together forming the staircase formwork frame. Two protective side panels 5 are fixedly installed on both sides of the construction base slab 1, primarily serving a protective function to prevent grout overflow during concrete pouring, while also enhancing the overall rigidity of the formwork structure.

[0039] Main clamping plates 10 are fixedly installed on the bottom surface of the top template 2 and the bottom surface of the stair template 3. The cross-section of the main clamping plate 10 is T-shaped, and the top surface of the stair template 3 is provided with a main clamping groove 11 for engaging with the main clamping plate 10. This engaging structure can quickly position and fix each template during installation, improving construction efficiency, and also helps to enhance the tightness of the connection between templates.

[0040] Multiple reinforcing connection mechanisms 4 are fixedly installed at the connection points between the top template 2 and the stair template 3, the connection points between two adjacent stair templates 3, and the connection points between the stair template 3 and the construction base plate 1. Specifically, the reinforcing connection mechanism 4 includes a first connecting plate 41, a second connecting plate 42, and reinforcing ribs 43. A first locking block 7 is fixedly installed on the side wall of the first connecting plate 41. A first locking groove that mates with the first locking block 7 is opened on the bottom side of the top template 2 and the bottom side of the stair template 3. The initial positioning and connection of the reinforcing connection mechanism 4 is achieved through the cooperation of the first locking block 7 and the first locking groove. The second connecting plate 42 is perpendicular to the first connecting plate 41 and integrally formed. A second locking block 8 is fixedly installed on the side wall of the second connecting plate 42. A second locking groove that mates with the second locking block 8 is opened on the top side of the stair template 3 and the bottom upper surface of the construction base plate 1, further reinforcing the connection. The cross-section of the first locking block 7 and the second locking block 8 is T-shaped to ensure the stability of the connection and prevent the reinforcing connection mechanism 4 from detaching from the top template 2, the stair template 3, and the construction base plate 1. A reinforcing rib 43 is fixedly installed at the connection between the first connecting plate 41 and the second connecting plate 42 to enhance the strength of the entire reinforced connection mechanism 4, enabling it to better withstand the pressure generated during concrete pouring. Multiple first mounting holes are provided on both the first connecting plate 41 and the second connecting plate 42. First threaded holes corresponding to the first mounting holes are provided on the top template 2, the stair template 3, and the construction base plate 1. Fixing bolts 9 are threaded through the first mounting holes and connected to the first threaded holes. By threading the fixing bolts 9 through the first mounting holes and connecting them to the first threaded holes, the components are tightly connected together, further preventing loosening at the template connections.

[0041] Multiple fixed support mechanisms 6 are respectively installed on the two protective side plates 5 and used to fix them to the ground. In this embodiment, there are four fixed support mechanisms 6, respectively installed on the outer surfaces of both ends of the two protective side plates 5 to ensure stability. Specifically, each fixed support mechanism 6 includes a slider 61, a support plate 62, a mounting plate 63, and a support rod 67. The slider 61 is vertically slidably installed on the protective side plate 5 and locked by a locking assembly. One end of the support plate 62 is rotatably connected to the slider 61, and one end of the mounting plate 63 is rotatably connected to the other end of the support plate 62. When the mounting plate 63 is in a horizontal state, its bottom surface height is the same as the bottom surface height of the protective side plate 5. The mounting plate 63 has several second mounting holes 64. One end of the support rod 67 is rotatably connected to the protective side plate 5, and the other end is provided with a connecting hole 68 for connecting to the middle of the support plate 62. The support rod 67 can be bolted to the middle of the support plate 62 after the support plate 62 is unfolded, which further enhances the support strength of the fixed support mechanism 6 and makes the support plate 62 more stable and less prone to deformation when subjected to pressure.

[0042] The locking assembly includes a slide groove 65 and two fastening bolts 66. The slide groove 65 is located on the side of the protective side plate 5. The slider 61 is slidably disposed within the slide groove 65. The two fastening bolts 66 are screwed onto the end face of the protective side plate 5 and extend into the top and bottom of the slide groove 65, respectively, to abut against the slider 61. After adjusting the position of the slider 61, the fastening bolts 66 are tightened to firmly abut against the slider 61, preventing the slider 61 from sliding during construction and ensuring the stability of the fixed support mechanism 6. In this invention, to further improve stability, positioning holes for the fastening bolts 66 can be provided on the side wall of the slider 61.

[0043] The specific operating steps of this utility model are as follows:

[0044] First, the construction base plate 1 is fixed at the construction site according to the design position and slope requirements. Then, the top formwork 2 and the stair formwork 3 are installed respectively. The top formwork 2 and the multiple stair formwork 3 are positioned and installed on the upper surface of the construction base plate 1 through the cooperation of the main clamping plate 10 and the main clamping groove 11. The protective side plates 5 are fixed to the two sides of the construction base plate 1 with bolts.

[0045] After the initial installation of the template is completed, the reinforcing connection mechanism 4 is installed. The first locking block 7 of the first connecting plate 41 is aligned with the first locking groove on the bottom side of the top template 2 or the bottom side of the stair template 3. Simultaneously, the second locking block 8 of the second connecting plate 42 is aligned with the second locking groove on the top side of the stair template 3 or the bottom upper surface of the construction base plate 1. The first locking block 7 and the second locking block 8 are then inserted into the first and second locking grooves respectively. Then, the fixing bolt 9 is inserted into the first mounting hole and tightened to ensure a tight connection with the first threaded hole.

[0046] Then, install the fixed support mechanism 6 on the protective side plate 5. Loosen the two fastening bolts 66, slide the slider 61 downwards, and then tighten the fastening bolts 66 below the slide groove 65 to fix the slider 61. Rotate the support plate 62 and the support rod 67. When the support rod 67 is in a horizontal state, fix the end of the support rod 67 to the middle of the support plate 62 with bolts. Then rotate the mounting plate 63 to a horizontal state and fix the mounting plate 63 to the ground with bolts through the second mounting hole 64 on the mounting plate 63.

[0047] After the template and various mechanisms are installed, concrete can be poured into the template through the pouring port 20 on the top template 2.

[0048] This utility model enhances the stability of the connection between templates and the stability of the overall structure by setting up a reinforcing connection mechanism 4 and a fixed support mechanism 6, thereby avoiding problems such as grout leakage and template deformation during concrete pouring and improving the construction quality and efficiency of the staircase.
