[0003] Existing staircase auxiliary support devices typically have several drawbacks. First, their supports are unstable and prone to tilting or damage due to uneven load distribution or improper use, making it difficult to ensure safety during use. Second, the structural design of existing devices is often not standardized, resulting in difficulties in assembly and insecure fixing, causing inconvenience to construction workers. In addition, these devices often lack flexibility and cannot be effectively adjusted according to the dimensions of different staircases, including the inability to adjust the length, width, and angle of the supports. Consequently, the auxiliary support devices cannot be fully adapted to different types and shapes of staircases, failing to meet diverse construction needs.

[0124] In summary, a more specific embodiment of this utility model is as follows:

[0125] Before using the above-mentioned design structure for staircase construction formwork support component, it is necessary to install the auxiliary support device component of the design structure that has already been manufactured as a backup.

[0126] The specific installation steps are as follows:

[0127] During installation, the upper support frame 1 in this embodiment is assembled from three upper support members 11 and three sets of upper connecting locking members 12; wherein, the three upper support members 11 include: three upper fixed connecting members 111, nine upper movable extension members 112 and six upper fasteners 113; the three sets of upper connecting locking members 12 include three middle connecting rods 121, six end connecting rods 122, six locking sleeves 123 and eighteen locking nuts 124;

[0128] During the assembly of the upper support frame 1, the operator first splices the nine upper movable extension pieces 112 into three sets of upper extended support pieces of equal length. Then, one end of each of the three sets of upper extended support pieces is threaded onto the non-rotating connection end of the three upper fixed connectors 111. Next, each set is secured together using an upper fastener 113, firmly connecting the upper movable extension pieces 112 fitted into the upper fixed connectors 111. Subsequently, the operator connects three central connecting rods 121 to both ends and the middle of one of the upper support pieces 11. One of the central connecting rods 121 connects the two outer upper movable extension pieces 112 together, and the middle connecting rod 121 is threaded into the connecting hole of the upper fixed connector adjacent to the one initially installed at the upper fixed connector 111. Another central connecting rod 121 is inserted into the third upper fixed connecting hole at the other end of the upper fixed connecting member 111. Then, the middle parts of the three central connecting rods 121 are all on the upper fixed connecting member 111. Next, the locking nuts 124 are sleeved on both ends of each central connecting rod 121. After tightening the locking nuts 124, they are fixed on the upper fixed connecting member 111. The assembly steps of the other two upper fixed connecting members 111, other end connecting rods 122, and locking nuts 124 are the same as the connection method of the central connecting rods 121, and will not be repeated here. Finally, the locking sleeves 123 are threaded between the corresponding central connecting rods 121 and end connecting rods 122. After adjusting the overall spacing, the assembly of the upper support frame 1 is completed.

[0129] When assembling the bottom support frame 2, the bottom support frame 2 is spliced ​​together by three bottom support parts 21 and three sets of bottom connecting locking parts 22; the assembly steps of the bottom support frame 2 are the same as the assembly method of the upper support frame 1 mentioned above, and will not be repeated here; after the bottom support frame 2 is assembled, the operator will snap the non-upper movable extension part 112 end of the upper support frame 1 into the bottom fixed connector 211 at the non-bottom movable extension part 212 end of the bottom support frame 2, and then connect the upper support frame 1 and the bottom support frame 2 together by bottom fasteners 213 respectively. The thickness of the rotating end of the upper support frame 1 is slightly smaller than the width of the gap of the bottom fixed connector 211.

[0130] When assembling the support adjustment component 3, connect the threaded end of the upper connector 32 to one end of the adjustment part 31, and then connect the threaded end of the lower connector 33 to the other end of the adjustment part 31, thus completing the assembly of the support adjustment component 3. Three support adjustment components 3 are used. The upper part of each support adjustment component 3 is connected to the outside of the upper fixed connector connection holes of the two upper movable extension parts 112 of the corresponding upper support component 11 that are not yet locked by fasteners. The lower part of each support adjustment component 3 is connected to the upper fixed connector connection holes of the two lower movable extension parts 212 of the corresponding bottom support component 21 that are not yet locked by locking parts by locking components. After the three support adjustment components 3 are connected, the assembly of the complete support adjustment component 3 with the upper support frame 1 and the bottom support frame 2 is completed.

[0131] The tray 4 is installed by welding it at equal intervals along the width direction of the upper support frame 1 to each upper support member 11 or by detaching it from each upper support member 11.

[0132] Before use, the operator selects the appropriate upper support frame 1, bottom support frame 2, support adjustment parts 3 and tray 4 according to the length and width of the stair template 6 and assembles them. After assembly, they are ready for use.

[0133] In use, the assembled formwork support assembly for stair construction is moved to the stair formwork 6 construction site. Then, the operator uses hoisting equipment to fit the stair formwork 6 onto the pallet 4. Next, the operator can adjust the angle between the upper support frame 1 and the bottom support frame 2 by using the support adjustment part 3. By rotating the adjustment part 31, the distance between the upper support frame 1 and the bottom support frame 2 can be adjusted to achieve the installation angle and height of the stair formwork 6.

[0134] In the above-mentioned use, if the stair formwork 6 cannot reach the predetermined height when the formwork support component used for stair construction is installed, multiple supports 5 can be laid out in advance to fix the supports 5 to the ground. Then, the formwork support component used for stair construction can be placed on top of the supports 5, so that the support bracket 52 and the bottom support frame 2 are firmly locked together, and the stair formwork 6 can be installed and used. If it is necessary to adjust the width of the upper support frame 1, the locking sleeve 123 can be adjusted for fine adjustment or the width can be adjusted by loosening the locking nut 124 on the end connecting rod 122. If it is necessary to adjust the length of the upper support frame 1, simply increase the number of upper movable extension parts 112 and then connect and fix them by the lower connecting locking parts 12 or the upper fasteners 113. The width adjustment and length adjustment of the bottom support frame 2 are the same as the adjustment method of the upper support frame 1, and will not be described again here.

[0135] Example 2

[0136] This embodiment 2 is the same as embodiment 1, except that, as Figure 1 and Figure 3 As shown, it also includes a support frame 5;

[0137] The support frame 5 includes:

[0138] Support rod 51, one end of which is connected to the ground;

[0139] Support bracket 52 is connected to the other end of support rod 51 and is used to support the bottom support frame 2.

[0140] More specifically, the support rod 51 is a square or circular columnar structure, and a support base is connected to the bottom of the square or circular columnar support rod 51. The four corners of the support base are provided with mounting and tightening holes.

[0141] The support bracket 52 is an inverted, U-shaped, or C-shaped plate-like component.

[0142] When the above design structure is in use, if it is necessary to lengthen the device, the operator only needs to use the support frame 5 to support and raise the utility model.

[0143] Finally, as time goes by, once all the construction work is completed, the operators only need to dismantle this utility model according to the actual construction requirements and standards. After dismantling, the operators clean and repair each component and then transport it to the designated tool storage warehouse for storage using appropriate handling equipment or manually, so that it can be reused next time.
