As shown in Figures 1 to 5, the present invention provides an aluminum alloy formwork support system, which includes a plurality of support rods 1 arranged in a rectangular matrix and an aluminum alloy formwork provided on the top of the support rods 1. Each support rod 1 includes the first section 2 and the second section 3. The second section 3 is fixedly installed on the ground. The first section 2 and the second section 3 are movably connected and a locking lifting component 4 is provided at this connection position.

In the construction of aluminum alloy formwork, vertical support rods 1 are usually used to support the aluminum alloy formwork at the top (this type of formwork is mostly used for pouring roofs). In addition, inclined support rods are also used to support the longitudinal Vertical aluminum alloy formwork (this type of formwork is mostly used for pouring walls). In the actual use of the vertical support rod 11, workers usually lift the first section of the hand-held support rod 1 to a position close to the top aluminum alloy formwork, and then rotate the spiral sleeve 14 provided on the second section 3 Make fine adjustments and place the first section against the top aluminum alloy template to form support. However, in the pouring process of some buildings, the number of vertical support rods 1 is very large, even as many as dozens or hundreds. However, the current workers still adjust the support rods 1 one by one and install the spiral sleeves 14 in circles to support the body extension of the support rod 1. This process requires a lot of work and makes the workers' work difficult. low efficiency.

Therefore, the present invention provides an aluminum alloy formwork support system to improve the current situation of troublesome operations for workers. During construction work, the vertical support poles 1 are arranged in a rectangular matrix. This device connects the support rods in the rectangular square array to form a whole, and then lifts them simultaneously to achieve the initial substantial lifting. Then it drives the movement of multiple locking lifting components 4 through the linkage device 6, and finally lifts multiple locking lifting components 4. One rod 2 is synchronously fine-tuned to achieve the purpose of contact support.

As shown in Figure 2, each first section 2 is provided with a plug-in hole 7, wherein the plug-in holes 7 on two diagonally adjacent first sections 2 are arranged oppositely, and the two ends of the connecting rod 5 are respectively Insert into two diagonally adjacent plug holes 7, and the connecting rods 5 between every four adjacent first sections 2 are arranged crosswise to form an X-shaped grid.

It can form better support for the aluminum alloy formwork. Supporting the resisting block 10 in a cross form can ensure the dispersion of the force and achieve a better supporting effect.

If each first section is connected in an S-shaped manner (multiple first sections 2 are connected in sequence through the connecting rod 5), it will not only be difficult to maintain the stability of the multiple first sections 2 together, but it will also be inconvenient to add a holding block. 10 (requires additional mounting brackets).

During the concrete pouring process, great stress is exerted on the aluminum alloy formwork. In order to prevent the aluminum alloy formwork from deforming, various process requirements are usually added during the last shift of manufacturing the aluminum alloy to ensure that it is difficult to deform under pressure. Therefore, in order to enhance the bearing capacity of the aluminum alloy formwork, in addition to the support points of the first section, a resisting block 10 is also provided as a support point at the intersection of the two connecting rods 5 for better support.
