[0024] Please see Figure 1-4 ,

[0025] Example 1: A stair formwork erection device for building construction includes a stair formwork body 1. Three sets of formwork erection support components 2 are evenly and symmetrically arranged at the bottom end of the stair formwork body 1. Two stability enhancement components 3 are symmetrically arranged on both sides of the formwork erection support components 2.

[0026] The template support assembly 2 includes a support base 201 set at the bottom of the stair template body 1. The top of the support base 201 has an adjustment slot 202. The side of the top of the support base 201 has a fixing screw hole 203. A fastening bolt 204 is inserted into the fixing screw hole 203. The top of the support base 201 has a top support column 205. Two bottom support columns 206 are vertically arranged on both sides of the bottom end of the top support column 205. The bottom end of the bottom support column 206 is inserted into the adjustment slot 202. Two end screw holes 207 are symmetrically opened at both ends of the top support column 205. A side wall fixing bolt 208 is inserted into each end screw hole 207. A connecting sleeve 209 is sleeved on the side wall fixing bolt 208. The top of the connecting sleeve 209 is connected to a side wall contact plate 210.

[0027] The stability enhancement component 3 includes end connecting frames 301 symmetrically arranged on the bottom sides of both ends of the top support column 205. A grounding support rod 302 is inserted into the end connecting frame 301. The top end of the grounding support rod 302 is rotatably connected to the end connecting frame 301 by a rotating pin 303. A grounding fixing plate 304 is provided at the bottom end of each grounding support rod 302. The grounding fixing plate 304 is rotatably connected to the bottom end of the grounding support rod 302 by a pin. A grounding screw 305 is inserted into each grounding fixing plate 304.

[0028] Example 2: The difference between this example and Example 1 is that a support plate is provided at the bottom of the support base 201.

[0029] This effectively increases the contact area between the support base 201 and the ground, thereby improving the support stability of the support base 201.

[0030] Example 3: The difference between this example and Example 1 is that the end of the fastening bolt 204 is provided with anti-slip texture, and the end of the fastening bolt 204 abuts against the side wall of the bottom support column 206 inserted into the adjustment slot 202.

[0031] This allows the end of the fastening bolt 204 to abut against and fix the side wall of the bottom support column 206, which is pulled upward from the adjustment slot 202.

[0032] Example 4: The difference between this example and Example 1 is that the end of the side wall fixing bolt 208 is provided with a rotating connecting block.

[0033] This makes it easier for users to rotate the side wall fixing bolt 208.

[0034] In this embodiment, since the existing construction of stair formwork in building construction mostly uses support columns erected at the bottom of the formwork for support, when concrete is poured on the surface of the formwork to bear pressure, the formwork may shift laterally. At this time, the support columns set at the bottom of the stair formwork alone are not suitable.

[0035] In summary, during specific implementation, when a user needs to assemble the stair formwork body 1 in building construction, the user can first support the bottom plate of the stair formwork body 1 using the formwork assembly support component 2, so that the top support column 205 in the formwork assembly support component 2 fits against the bottom plate of the stair formwork body 1. The bottom end of the top support column 205 is inserted into the adjustment slot 202 through the bottom support column 206, thereby allowing the height of the bottom support column 206 and the top support column 205 to be adjusted. This results in different support heights for every two sets of top support columns 205 and bottom support columns 206 in the formwork assembly support component 2, which can effectively meet the inclination slope setting of the stair formwork body 1 and better support the bottom of the stair formwork body 1.

[0036] Next, upper side wall fixing bolts 208 are inserted into the end screw holes 207 opened at both ends of the top support column 205. A connecting sleeve 209 is fitted on the side wall fixing bolt 208. The user can rotate the side wall fixing bolt 208 so that the side wall fixing bolt 208 abuts against the connecting sleeve 209, so that the side wall abutting plate 210 connected on the connecting sleeve 209 can abut and fix the two sides of the stair formwork body 1.

[0037] Furthermore, the grounding support rod 302 in the stability enhancement component 3 contacts the ground, thereby providing stable support to both sides of the top support column 205. This ensures stable support of the bottom of the stair formwork body 1 by the formwork erection support component 2. When concrete is poured on the stair formwork body 1, the side wall contact plates 210 on both sides of the top support column 205 can contact and clamp the side plates of the stair formwork body 1, and the grounding support rod 302 provides support to both sides of the top support column 205. This effectively prevents the stair formwork body 1 from shifting laterally when concrete is poured on it, ensuring that the stair formwork body 1 is more stable during construction and use, improving the stability of the stair construction, and facilitating user use.
