[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] The present invention provides a single-sided formwork structure for a side wall backed by a ground-connected wall and its construction method. This structure reduces the appearance of through-holes in the ground-connected wall by providing load-bearing members, thus preventing the overall strength of the wall from being compromised. Furthermore, it utilizes diagonal braces and scaffolding to respectively support the bottom and top of the formwork, thereby reinforcing the formwork. The following describes this single-sided formwork structure for a side wall backed by a ground-connected wall and its construction method.

[0034] See Figure 1 , showing a side view of a side wall single-sided formwork structure and its construction method of the present invention. Figures 1 to 6 , the structure of a side wall single-sided formwork structure backed by a ground-connected wall and a construction method thereof is described in the present invention.

[0035] See Figure 1 The present invention provides a single-sided formwork structure for a side wall backed by a ground-connected wall and a construction method thereof, comprising: a formwork 15, a transverse rib 16, a load-bearing member connected to the ground-connected wall A, and a plurality of load-bearing members arranged on the ground-connected wall, the formwork 15 is supported on the ground and adheres to the end of the load-bearing member away from the ground-connected wall A, the transverse rib 16 is connected to the side of the formwork 15 away from the ground-connected wall A, and a plurality of diagonal braces are arranged on the formwork 15, which are supported on the corresponding transverse rib 16 and inclined, and the other end of the diagonal brace is supported on the ground, and a scaffold is horizontally supported on the corresponding transverse rib 16, and the bottom of the scaffold is supported on the ground, and the formwork 15 is supported by the scaffold and the diagonal brace to achieve support and reinforcement of the formwork 15.

[0036] Preferably, if Figure 1 As shown, the end of the load-bearing member can extend outward from the ground-connected wall and be in contact with the formwork 15, so that the load-bearing member can be connected between the ground-connected wall and the formwork 15 at the same time, and the position of the formwork 15 can be fixed by setting the load-bearing member, so that the distance between the formwork 15 and the ground-connected wall is always consistent, so that the position of the formwork 15 will not be offset during the construction process, and when pouring, the poured mud will apply an outward thrust to the formwork 15. At this time, the formwork 15 is supported by the diagonal bracing part and the scaffolding, which acts in the opposite direction to the thrust generated by the pouring, thereby improving the support strength of the formwork 15 and preventing the position of the formwork 15 from moving.

[0037] Furthermore, the cross ribs 16 are grouped in two and fixed to the formwork 15 with fasteners 17. The fasteners 17 can be expansion bolts or any fastenable components, and multiple groups are arranged at intervals from bottom to top on the side of the formwork 15 to provide support points for the diagonal bracing parts and the scaffolding on the side of the formwork 15.

[0038] See Figure 5 、 Figure 6In a specific embodiment of the present invention, the force-bearing member includes a mounting rod 11 connected to the ground-connected wall A, and the end of the mounting rod 11 extends outward from the ground-connected wall A to form a cantilevered end. The force-bearing member also includes a connecting plate 12 connected to the cantilevered end and four screws 13 connected to the connecting plate 12. The four screws 13 extend in different directions and are in contact with the template 15. A water stop plate 14 is connected to the corresponding position on the screw 13. One side of the water stop plate 14 is in contact with the template 15, and the connecting plate 12 is L-shaped.

[0039] Preferably, if Figure 5 、 Figure 6 As shown, when the mounting rod 11 is connected to the ground-connected wall A, only one end needs to be reserved on the outside of the ground-connected wall A for installing the connecting plate 12, and it does not penetrate the ground-connected wall A. Therefore, the number of holes on the ground-connected wall A can be reduced, and the overall strength of the ground-connected wall A can be avoided from being affected.

[0040] Furthermore, a nut is screwed onto the mounting rod 11. By adjusting the nut along the mounting rod 11 toward the ground connection wall A, the nut gradually approaches the ground connection wall A to squeeze the connecting plate 12, so that the connecting plate 12 is tightly attached to the ground connection wall A and fixed.

[0041] Furthermore, four screws 13 are connected to the connecting plate 12, and the screws 13 can be extended into the template 15 to connect and fix one side of the template 15, and a water stop plate 14 is provided on the screw 13 to increase the water penetration path, thereby preventing moisture in the mud from penetrating from the template 15.

[0042] See Figure 1 、 Figure 2 、 Figure 3 In a specific embodiment of the present invention, the diagonal bracing portion includes a plurality of first jacking supports 1 supported on the transverse ribs 16, diagonal bracing rods 2 connected to the corresponding first jacking supports 1, a first cross bar 3 connected to the plurality of diagonal bracing rods 2, and a first fastener 4 connected at the intersection of the diagonal bracing rod 2 and the first cross bar 3. The diagonal bracing portion also includes a plurality of anchor rods 5 supported close to the ground and located on one side of the first cross bar 3, and one end of the anchor rod 5 is set in the ground.

[0043] Preferably, if Figure 1 、 Figure 2 、 Figure 3 As shown, when the side wall is being poured, the bottom of the formwork 15 is subjected to the greatest force, so the first jack 1 can support the diagonal brace 2 below the transverse rib 16, and use the diagonal brace 2 to reinforce the bottom of the side of the formwork 15, so that the bottom of the formwork 15 is sufficiently stable when pouring the side wall to avoid being affected by the impact force generated during pouring.

[0044] Furthermore, the distance between multiple anchor rods 5 can be set according to the placement distance of the diagonal braces 2 during construction. One anchor rod 5 can be placed corresponding to each diagonal brace 2 to avoid uneven support force of the diagonal brace 2 on the bottom of the formwork 15 when pouring the side wall, further strengthening the support effect of the diagonal brace 2 on the formwork 15.

[0045] See Figure 1 、 Figure 2 、 Figure 4 In a specific embodiment of the present invention, the scaffolding includes a plurality of second top supports 6 supported on corresponding transverse ribs 16, a second cross bar 7 connected to the corresponding second top supports 6, at least two columns 8 connected to the plurality of second cross bars 7, a second fastener 9 connected at the intersection of the second cross bar 7 and the column 8, and a plurality of docking rods 10 connected between two adjacent columns 8, and the second cross bar 7 and the column 8 are perpendicular to each other.

[0046] Furthermore, if Figure 1 、 Figure 2 、 Figure 4 As shown, the second cross bar 7 not only connects the column 8 and the template 15, but also fixes the bottom of the column 8, so that the distance between the column 8 and the template 15 is always consistent, avoiding displacement of the supporting part when supporting the template 15. The connection is achieved by connecting the docking rod 10 between adjacent columns 8, so that multiple columns 8 can be placed together and connected firmly together, avoiding skewing of the columns 8 during the support process.

[0047] Furthermore, the second fastener 9 is used to lock the intersection of the diagonal brace 2 and the second cross bar 7, so that the diagonal brace 2 and the second cross bar 7 are quickly connected and can also be quickly disassembled after the construction is completed.

[0049] Provide a load-bearing member and connect the provided load-bearing member to the side of the ground-connected wall A close to the side wall to be constructed;

[0050] Providing a template 15, and placing the provided template 15 on the ground facing the ground connecting wall 16, so that the template 15 contacts the end of the load-bearing member;
