Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stair formwork, in particular to a reinforced concrete stair formwork construction device. Background Art
[0002] The formwork construction of reinforced concrete staircases generally takes the following forms: (1) using single-film laminated boards as the tread formwork, with small wooden strips connected and fixed with large wooden planks; (2) using laminated laminated boards to be customized into boxes to fully cover the stair treads; (3) using aluminum alloy formwork to be customized according to the staircase dimensions in the drawings. These formwork structures have problems such as inconvenience for workers to walk and poor forming construction quality. Specifically: (1) Formwork construction is difficult and inefficient, and is prone to deformation during concrete pouring, resulting in poor forming effects and difficult quality control. It is also inconvenient for workers to walk; (2) during concrete pouring, the quality of the concrete cannot be seen due to the full enclosure, and exhaust is not smooth, which affects the forming quality and poor forming effects.

[0005] Furthermore, the vertical baffle wood is divided into upper wood and lower wood, and both the upper and lower wood are clamped and fixed between the two vertical baffle panels. The upper wood is the same length as the vertical baffle panel, and both ends of the lower wood extend to the outside of the end of the vertical baffle panel.
[0006] Furthermore, the inner sidewalls of the side baffle panels are evenly provided with sockets, and the ends of the stair tread vertical baffles are clamped in the sockets. The sockets play a role in limiting and fixing the stair tread vertical baffles, ensuring a more stable structure.
[0007] Furthermore, the anchor hole is provided at the lower part of the socket, and the vertical baffle is inserted into the anchor hole, which is arranged at the lower part of the socket to ensure that the entire stair tread vertical baffle is fully embedded in the socket, thereby achieving higher stability.
[0008] Furthermore, galvanized sealing iron sheets are fixed on the outer side of the vertical baffle panel to increase its turnover times.
[0009] Compared with existing technologies, this new design offers the following advantages: It increases the contact area between stair treads and pedestrians' shoes; the vertical baffles are fixed to the side baffles via mortise and tenon joints, resulting in a simple structural connection, strong stability, and convenient walking for construction workers; the spaced treads reduce the loss of wood and formwork, saving costs; the concrete pouring process beneath the formwork structure is clearly visible, air exhaust is smoother, and pouring quality is guaranteed.

[0015] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.
[0016] like Figures 1 to 3 As shown, the utility model provides a reinforced concrete stair formwork construction device, including stair tread side baffles and stair tread vertical baffles 4; the stair tread side baffles are composed of a top baffle 2, a side baffle panel 1 and a bottom baffle 3, a row of anchor holes 9 are evenly distributed on the upper edge of the side baffle panel 1, and the top baffle 2 and the bottom baffle 3 are respectively fixed to the upper and lower edges of the side baffle panel 1; the stair tread vertical baffle 4 is composed of a vertical baffle panel 7 and a vertical baffle wooden square, the vertical baffle wooden square is fixed under the vertical baffle panel 7, and both ends extend to the outside of the end of the vertical baffle panel 7 respectively; the extended part of the vertical baffle wooden square is inserted into the anchor hole 9.
[0017] The vertical baffle wood is divided into an upper wood 8 and a lower wood. Both the upper and lower wood are clamped and fixed between the two vertical baffle panels 7. The upper wood 8 is the same length as the vertical baffle panel 7. The two ends of the lower wood extend to the outside of the end of the vertical baffle panel 7, and the protruding parts serve as the core 5.
[0018] In some preferred embodiments, Figure 4 As shown, the inner wall of the side panel 1 is uniformly provided with sockets 6, into which the ends of the stair tread baffles 4 are inserted. These sockets 6 secure the stair tread baffles 4, ensuring a more stable structure. Anchor holes 9 are provided below these sockets 6. These anchor holes 9 receive the baffle planks, positioned below the sockets 6 to ensure that the entire stair tread baffle 4 is fully embedded within them, enhancing stability.
[0019] Production process: A laminated multilayer board is cut into a parallelogram according to the drawing as the side panel 1. Sockets 6 are evenly spaced on the upper inner wall of the side panel 1 to secure the stair treads 4. An anchor hole 9 is provided at the bottom of each socket 6 to receive the insert 5 of the stair tread 4.
[0020] Two vertical baffle panels 7 sandwich the upper and lower wood planks and secure them with nails. The top edge of the upper wood plank 8 is flush with the vertical baffle panels 7 and its length is the same as the vertical baffle panels 7, increasing their strength, rigidity, and stability. The ends of the lower wood plank extend to the outside of the ends of the vertical baffle panels 7 to serve as inserts 5. Inserts 5 are inserted into anchor holes 9, and the vertical stair tread 4 is snapped into sockets 6, ensuring that the side edges of the vertical stair tread 4 are tightly attached to the stair tread side baffle panels 1, stably clamping the vertical stair tread 4 between the stair tread side baffles.
[0021] At the upper and lower edges of the side panel 1, wooden square strips are fixed with iron nails as the top and bottom bars 2 and 3. After fixing, the thickness of the stair tread formwork surface is widened, workers walk smoothly and conveniently, the mortise and tenon structure is firmly fixed, and the wooden square increases rigidity and does not deform.
[0022] This technical solution has been put into practical application on site, and it has been found to have the following advantages compared with the original stair formwork structure: (1) The formwork connection is firm, the construction is convenient, and the efficiency is high; (2) The loss rate of wood and formwork is reduced, saving costs; (3) The number of processes is reduced, and the construction speed is fast; (4) Workers can walk on it, and the strength, stiffness, stability and force-bearing performance are high; (5) The staircase forming effect is good, the quality is easy to control, and the turnover rate is high; (6) It has a wide range of applications and no safety hazards.
[0023] Finally, it should be noted that the above-listed examples are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and modifications fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
