Specific implementation

[0041] In order to make the technical problem, technical scheme and beneficial effect of the utility model to be solved more clear and obvious, the utility model is further described in detail below by combining with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0042] Please see Figure 1 And Figure 2 Now a kind of assembled modular reinforcing back latticed provided by the utility model will be described. A kind of assembled modular reinforcing back latticed, including back latticed body 1. Back latticed body 1 includes two main pipes 11 and the connecting pipe 12 fixedly connected between the two main pipes 11. Wherein, each main pipe 11 both sides have the cavity 13 formed by bending, each cavity 13 is independent and extends along the length direction of main pipe 11. Two main pipes 11 are parallel to each other, and there is a gap between the two main pipes 11, which allows the tensioning screw rod to pass through the gap between the two main pipes 11.

[0043] Compared with the existing C-shaped steel back bar, the two sides of the main pipe 11 are bent to form two independent cavities 13, which makes the cross section of the main pipe 11 B-shaped, forms multiple reinforcing support structures in the width direction of the main pipe 11, and makes the cross section of the main pipe 11 more excellent in performance and stronger in bending resistance. At the same time, the cavities 13 extend along the length direction of the main pipe 11, so that the overall structural strength of the main pipe 11 is strengthened. The two main pipes 11 form the back bar body 1 through the connecting pipe 12, and the two main pipes 11 interact and support each other, which can further strengthen the structural strength of the back bar body 1, so that the back bar body 1 is less likely to deform when supporting the building template.

[0044] Optionally, the shape of the cavity 13 can be rectangular, triangular, trapezoidal, etc.

[0045] In some embodiments, referring to Figure 2 The main pipe 11 includes a first web 111, two groups of first rib plates 112, two groups of second webs 113, and two groups of second rib plates 114. The two groups of first rib plates 112 are respectively fixedly arranged on the two sides of the first web 111 in the width direction. The two groups of second webs 113 correspond to the two groups of first rib plates 112 one by one, and the second web 113 is fixedly arranged on the side of the corresponding first rib plate 112 close to the connecting pipe 12. The two groups of second rib plates 114 correspond to the two groups of second webs 113 one by one, and the second rib plate 114 is fixedly arranged between the first web 111 and the corresponding second web 113. The first web 111, the first rib plate 112, the second web 113, and the second rib plate 114 are integrally formed and surround the cavity 13. The second web 113 and the connecting pipe 12 are fixedly connected.

[0046] In the width direction of the main pipe 11, the first web 111, the first rib plate 112, the second web 113, and the second rib plate 114 jointly act as reinforcing supports, making the stress performance of the main pipe 11 more excellent and the carrying capacity stronger, and more easily keeping stable and not deforming when bending. By fixedly connecting the two groups of second webs 113 and the connecting pipe 12, the two groups of second webs 113 are reinforced, so that the positions of the two second webs 113 remain stable, ensuring the stability of the structure.

[0047] Based on the above embodiments, further, referring to Figure 2, the first web 111 and the second web 113 are parallel, the first rib 112 and the second rib 114 are parallel, and the first web 111 and the first rib 112 are perpendicular, so that the cavity 13 formed by the first web 111, the first rib 112, the second web 113 and the second rib 114 is rectangular. The rectangular cavity 13 is simple in structure and regular in shape, and can reduce the use of materials while increasing the bending stiffness and load-carrying capacity of the main pipe 11. In construction, the regular main pipe 11 is easier to fit on the surface of the building formwork, has a larger contact area with the building formwork, and has a better supporting effect on the building formwork.

[0048] In some embodiments, referring to Figure 1 and 2 , the backrest body 1 further comprises end plates 14 fixedly arranged at both ends of the main pipe 11. The end plates 14 close the ends of the cavity 13, so that the cavity 13 forms a closed space. The end plates 14 are fixedly connected with the first web 111, the first rib 112, the second web 113 and the second rib 114, thereby connecting the first web 111, the first rib 112, the second web 113 and the second rib 114 into a whole, improving the stability of the shape between the first web 111, the first rib 112, the second web 113 and the second rib 114, improving the structural strength, and ensuring that the shape of the main pipe 11 is not easily changed during use.

[0049] It should be understood that in the prior art, the main pipe 11 can be a square pipe, a C-shaped pipe or other shaped profiles.

[0050] In some embodiments, referring to Figure 3 , Figure 4 and Figure 5 , the modularized assembled reinforcing backrest further comprises straight connectors 2, the straight connectors 2 are connected with the backrest bodies 1 through bolts, and adjacent two backrest bodies 1 are spliced through the straight connectors 2. After the adjacent two backrest bodies 1 are connected through the straight connectors 2, the two backrest bodies 1 are kept in a parallel state, thereby realizing the extension connection between the backrest bodies 1 in the same direction.

[0051] Specifically, threaded pipes are fixedly arranged on the end plates 14. The straight connectors 2 are square pipes, and connection holes for bolts to pass through are formed on both sides of the straight connectors 2. In use, the end plates 14 are placed against the straight connectors 2, so that the threaded pipes are aligned with the connection holes, and the bolts are used to pass through the connection holes and be screwed with the threaded pipes, thereby realizing the fixation of the backrest bodies 1 and the straight connectors 2. The surfaces of the end plates 14 and the straight connectors 2 abut against each other, which can make the backrest bodies 1 and the straight connectors 2 fit more closely and be less likely to be skewed.

[0052] Based on the above embodiments, further, referring to Figure 3 ,Figure 4 and Figure 5 The connecting holes are distributed on the straight connecting piece 2, so that the connection position of the backrest body 1 on the straight connecting piece 2 can be freely selected according to actual conditions, so that the adjacent two backrest bodies 1 can be spliced into a variety of different shapes of combination bodies such as a straight combination body, a flat Z-shaped combination body and a vertical Z-shaped combination body through the straight connecting piece 2. At the same time, since the backrest body 1 is composed of two main pipes 11, two bolts are required to connect the backrest body 1 and the straight connecting piece 2, which further improves the stability of the connection between the backrest body 1 and the straight connecting piece 2 and improves the connection strength.

[0053] In some embodiments, referring to Figure 6 and Figure 7 The assembled modular reinforced backrest further comprises an angle connecting piece 3, the angle connecting piece 3 and the backrest body 1 are connected through bolts, and the adjacent two backrest bodies 1 are spliced through the angle connecting piece 3. After the adjacent two backrest bodies 1 are connected through the angle connecting piece 3, the two backrest bodies 1 are kept in a perpendicular state to each other, thereby realizing the extension connection in different directions between the backrest bodies 1.

[0054] Specifically, a threaded pipe is fixedly arranged on the end plate 14. The angle connecting piece 3 is an L-shaped pipe, and connecting holes for bolts to pass through are formed on both sides of the angle connecting piece 3. In use, the end plate 14 is abutted against the angle connecting piece 3, so that the threaded pipe and the connecting hole are aligned, and the bolt is used to pass through the connecting hole and be threadedly connected with the threaded pipe, thereby realizing the fixation of the backrest body 1 and the angle connecting piece 3. The surfaces of the end plate 14 and the angle connecting piece 3 abut against each other, which can make the backrest body 1 and the angle connecting piece 3 fit more closely, and the backrest body 1 and the angle connecting piece 3 are not prone to skewing and are more stable in connection.

[0055] In some embodiments, referring to Figure 8 and Figure 9 The assembled modular reinforced backrest further comprises a lap connecting piece 4, the lap connecting piece 4 is buckled on the backrest body 1, the lap connecting piece 4 has a containing space 41 for containing the backrest body 1, and a first waist-shaped hole for a tension rod to pass through is formed on the lap connecting piece 4.

[0056] Specifically, the lap connecting piece 4 is bent into a U shape to form the containing space 41 for containing the backrest body 1, and the containing space 41 is straight through along the length direction of the lap connecting piece 4. When the adjacent two backrest bodies 1 are inserted into the containing space 41 from both ends of the lap connecting piece 4 respectively, the two backrest bodies 1 will be in an aligned state under the action of the lap connecting piece 4.

[0057] The embodiment can guide the movement of the back lath body 1 through the overlapping piece 4, prevent dislocation of the two back lath bodies 1 during movement, and make the two back lath bodies 1 remain in an aligned state. In use, the two back lath bodies 1 are moved along the length direction of the overlapping piece 4, so that the spacing between the two adjacent back lath bodies 1 can be adjusted, thereby adapting to building templates of different sizes.

[0058] Based on the above embodiment, further, see Figure 8 The reinforcing edges 42 are integrally formed on both sides of the overlapping piece 4 in the width direction. The reinforcing edges 42 can abut against the surface of the building template, support the overlapping piece 4, and prevent the overlapping piece 4 from being skewed during use. Meanwhile, the reinforcing edges 42 can enhance the structural strength of the overlapping piece 4, so that the overlapping piece 4 is not prone to bending deformation.

[0059] In some embodiments, see Figure 10 and Figure 11 A connecting hole for a bolt is formed at one end of the overlapping piece 4, so that the back lath body 1 and the overlapping piece 4 can be fixedly connected through the bolt, thereby making the two adjacent back lath bodies 1 be in a perpendicular state, and expanding the flexibility of use of the overlapping piece 4. In use, the overlapping piece 4 can be used to splice the two adjacent back lath bodies 1 into a linear shape or an L shape according to the actual construction condition.

[0060] In some embodiments, see Figure 12 and Figure 13 The modularized reinforcing back lath further includes a diagonal pull piece 5, which includes a C-shaped sleeve 51, a triangular plate 52, a bearing plate 53, and a supporting plate 54. The C-shaped sleeve 51 is fixedly connected to the back lath body 1 through a bolt, the triangular plate 52 is fixedly arranged on the C-shaped sleeve 51, the bearing plate 53 is fixedly arranged on the triangular plate 52, and a second waist-shaped hole for a tensioning screw rod is formed in the bearing plate 53, and the supporting plate 54 is fixedly arranged on the triangular plate 52 and abuts against the back lath body 1. The two adjacent back lath bodies 1 are connected through the diagonal pull piece 5 and the tensioning screw rod, so that the two back lath bodies 1 are in a perpendicular state.

[0061] Specifically, see Figure 12 and Figure 13 A connecting hole for a bolt is formed in the C-shaped sleeve 51, and a connecting hole for a bolt is formed in the main pipe 11. The C-shaped sleeve 51 is inserted between the two main pipes 11, so that the connecting holes in the C-shaped sleeve 51 and the main pipe 11 are aligned, and then the C-shaped sleeve 51 can be fixed to the back lath body 1 through the bolt.

[0062] See Figure 12 and Figure 13The oblique edge of the triangular plate 52 is inclined at 45 degrees, so that the bearing plate 53 fixed on the oblique edge of the triangular plate 52 is also inclined at 45 degrees. The supporting plate 54 abutting against the backrest body 1 can support the oblique puller 5, so that the oblique puller 5 is not easy to be skewed on the backrest body 1, and the stability of the oblique puller 5 during use is improved. When the oblique puller 5 is used to connect two adjacent backrest bodies 1, the two backrest bodies 1 are in a perpendicular state, and the oblique puller 5 is connected to the end of the two backrest bodies 1 close to each other. Then, the counter-pulling screw is passed through the second waist-shaped hole of the two oblique pullers 5, and the nut is connected to the counter-pulling screw, so that the nut abuts against the bearing plate 53, and the connection combination between the two adjacent backrest bodies 1 is realized.

[0063] In summary, compared with the prior art, the two sides of the main pipe 11 are bent to form two independent cavities 13, so that the cross section of the main pipe 11 is B-shaped, and multiple support reinforcements are formed in the width direction of the main pipe 11, so that the cross section performance of the main pipe 11 is more excellent, and the bending resistance is stronger. At the same time, the cavities 13 extend along the length direction of the main pipe 11, so that the overall structural strength of the main pipe 11 is strengthened, and the two main pipes 11 form the backrest body 1 through the connecting pipe 12, and interact and support each other, so that the structural strength of the backrest body 1 is further strengthened, and the backrest body 1 is not easy to deform when supporting the building formwork.

[0064] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
