[0036] The top end of the force-bearing member 2 is hinged to the two ends of the support rod 1 respectively, and the force-bearing member 2 is closely arranged on the outer side of the template 9 to be reinforced;

[0037] The tie rod 3 is located below the support rod 1, and the tie rod 3 is located above the positioning plate 8. The tie rod 3 passes through the load-bearing component 2, and is fixed on the outside or inside of the load-bearing component 2 by a fixing device;

[0038] The positioning plate 8 is fixedly connected to the inner side of the force bearing member 2, the positioning plate 8 is provided with a first hole 81, the template to be reinforced 9 is provided with a second hole 91, and the position of the first hole 81 corresponds to the position of the second hole 91;

[0039] The pin 7 passes through the first hole 81 and the second hole 91 and is connected to the positioning plate 8 and the template to be reinforced 9 .

[0040] The tie rods are fixedly connected to the load-bearing components. During the pouring process, the height of the tie rods is limited to be always higher than the height of the formwork to be reinforced, thereby limiting the height of the tie rods to be always higher than the height of the strip foundation. After the pouring is completed, the tie rods are pulled out horizontally. During the process of pulling out the tie rods, they do not contact the already poured strip foundation, do not occupy the area of ​​the foundation pit, and do not need to increase the width of the foundation pit, effectively saving the land occupied area during the strip foundation construction process. During the pouring process, the expansion force generated by the formwork is transmitted to the support rod through the load-bearing components to prevent damage to the load-bearing components. The pins and positioning plates play a connecting role.

[0041] In a specific embodiment, it also includes a fixing nut 4 and a limiting nut 5. The fixing nut 4 is arranged on the outside of the load-bearing component 2 and is close to the load-bearing component 2. The limiting nut 5 is arranged on the inside of the load-bearing component 2 and is close to the load-bearing component 2. The fixing nut plays a role in reinforcing the load-bearing component to prevent the mold from expanding during the pouring process and causing the position of the load-bearing component to move. The limiting nut plays a role in controlling the width of the strip foundation and the template to be reinforced.

[0042] In a specific embodiment, threads are provided at both ends of the tie rod 3, which are correspondingly connected to the fixing nut 4 and the limiting nut 5, so that the tie rod and the load-bearing member are fixedly connected together.

[0043] In a specific embodiment, the upper portion of the pin 7 is connected to the limit nut 5 by a flexible connector 6 to prevent the pin from being lost during use.

[0044] In a specific embodiment, the diameter of the first hole 81 is the same as the diameter of the second hole 91 to facilitate the insertion of a pin.

[0045] The same purpose, such as Figure 2 The present invention also provides embodiment 2: a construction method for reinforcing a component using the strip foundation formwork, comprising the following steps:

[0046] Step 1: After the bottom elevation of the foundation pit meets the requirements, wooden beams 10 are respectively set on both sides of the strip foundation to be cast. The wooden beams 10 are perpendicular to the strip foundation to be cast, and the top elevation of the wooden beams 10 is equal to the bottom elevation of the template 9 to be reinforced. Figure 2 As shown;

[0047] Step 2: embed the steel pile 11 into the ground by no less than 30 cm. The length of the steel pile 11 is greater than the length of the template 9 to be reinforced. Install the template 9 to be reinforced on the outside of the steel pile 11. The template 9 to be reinforced is close to the steel pile 11. Figure 3 As shown;

[0048] Step 3: The inner side of the force-bearing component 2 is closely arranged on the outer side of the template 9 to be reinforced, and the force-bearing component 2 is inserted downward along the outer side of the template 9 to be reinforced;

[0049] Step 4: penetrate the tension rod 3 and set it on the force-bearing member 2, and install the fixing nut 4 and the limiting nut 5;

[0050] Step 5: hinge the support rod 1 to the top end of the load-bearing member 2;

[0051] Step 6: Insert the pin 7 into the first hole 81 and the second hole 91, and lock the fixing nut 4 and the limiting nut 5. After completing steps 3 to 6, Figure 4 As shown;

[0052] Step 7: Casting. The top view of the strip foundation casting process is as follows Figure 5 As shown;

[0053] Step 8: After the strip foundation concrete pouring is completed, the pin 7 is pulled out;

[0054] Step 9: Loosen the fixing nut 4 and the limiting nut 5;

[0055] Step 10: Pull out the tension rod 3, and remove the load-bearing component 2 and the support rod 1.

[0056] A construction method utilizing the strip foundation formwork reinforcement component is adopted to cast the strip foundation, the wooden planks play the role of controlling the elevation of the formwork, the steel piles play the role of measuring positioning and ensuring stability, and since the height of the tie rod is higher than the strip foundation, there is no need to increase the construction land of the strip foundation during the process of pulling out the tie rod, and there is no need to leave the PVC pipe inside the concrete after the casting is completed. The strip foundation formwork reinforcement component is easy to install and disassemble, which saves the time of pulling out the tie rod after the casting is completed, reduces the damage to the tie rod due to leakage accidents during the casting process, and improves the reuse rate of the tie rod, which can save land resources, speed up the construction schedule, reduce the investment in construction equipment, and improve construction stability.
