[0032] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present disclosure, and cannot be interpreted as a limitation of the present disclosure.

[0033] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0034] The embodiments of the present disclosure are described below in conjunction with Figures 1 to 5 The specific structure of the pier formwork 100 without pull rod provided by the embodiment of the present disclosure is described.

[0035] Specifically, in the pier formwork 100 without pull rod provided by the embodiment of the present disclosure, a support structure, a panel 1 and a back lath 2 are included.

[0036] The support structure can constitute the frame of the formwork 100 and can be composed of steel frames, support rods, connecting pieces and the like. Through accurate design and installation of each component, the stability of the formwork 100 during pouring can be ensured, and deformation and displacement can be avoided. The support structure can bear the weight of the formwork and the concrete thereon and safely transmit it to the foundation or the lower structure, so as to ensure the stability and safety of the formwork during pouring.

[0037] The panel 1 can be fixed by the support structure and constitutes a space for containing concrete, such as Figure 1The intermediate region is shown. The panel 1 is the main load-bearing and forming part in the tie-bar-free formwork 100, which can be directly in contact with the concrete, and its shape and size determine the final shape of the pier concrete. Optionally, the panel 1 can be made of high-strength and wear-resistant materials to effectively ensure the durability of the formwork 100 and the forming quality of the concrete.

[0038] The back braces 2 can be connected with the support structure and arranged outside the panel 1, as shown in Figure 1 The back braces 2 can be used to support and fix the formwork 100, so as to ensure that the formwork 100 does not deviate or deform when the concrete is poured. Optionally, the back braces 2 can be connected with the support structure by welding or other means. For example, the back braces 2 can be arranged along the longitudinal and transverse directions of the formwork 100 to form a stable support system; in the longitudinal direction, the back braces 2 can be arranged along the height direction of the pier column, as shown in Figure 5 , so as to support the vertical load of the formwork 100; in the transverse direction, the back braces 2 can be arranged according to the width and shape of the formwork 100, as shown in Figure 1 , so as to ensure the lateral stability of the formwork 100.

[0039] In the embodiments of the present disclosure, as shown in Figure 1 , the formwork 100 provided is arranged with diagonal tie bars 3 outside the panel 1 on the intersecting back braces 2 at the corners. The diagonal tie bars 3 can be arranged on the intersecting positions of the back braces 2 to improve the overall stability of the formwork 100. Moreover, the diagonal tie bars 3 are located outside the panel 1 and do not affect the pier body structure formed by pouring the concrete, so that the surface of the pier column is smooth, flat and free of tie bar scars. Compared with the arrangement of the through tie bars in the counter-tie formwork of the prior art, the arrangement of the diagonal tie bars 3 can also effectively improve the installation efficiency of the formwork.

[0040] Optionally, as shown in Figure 1 , the diagonal tie bars 3 can be arranged between each vertically intersecting back brace 2 arranged on the same horizontal plane to improve the overall stability of the formwork 100. Each position arranged with the diagonal tie bars 3 can include at least one, and the two ends of each diagonal tie bar 3 are respectively connected with different back braces 2. For example, as shown in Figure 1 , two diagonal tie bars 3 are arranged at the upper left corner position of Figure 1 , and the lengths of the diagonal tie bars 3 used are different due to the different distances from the arrangement position to the panel 1.

[0041] Optionally, to improve the rigidity of the formwork 100, a truss keel can also be arranged outside the back brace 2, as shown in Figure 2 , Figure 3 and Figure 5As shown, the truss keel includes a triangular truss 21 composed of a plurality of bars, thereby forming a structure with high strength and rigidity and good stability, even if the formwork 100 is subjected to a large load and impact force during the pouring of concrete, the formwork 100 can maintain good shape and positional stability. At the same time, the truss keel is simple to assemble and disassemble, which can save a lot of construction time and labor cost. In an example, the truss keel can also include a quadrilateral truss composed of a plurality of bars.

[0042] Optionally, the support structure can include a main rib 41, a vertical rib 42, and a horizontal rib 43. As shown in Figure 1 and Figure 4 The main rib 41 is arranged horizontally along the formwork 100 and is at least partially connected to the back rib 2. As an example, the main rib 41 is arranged along the outer side (the side away from the concrete) of the panel 1. As shown in Figure 2 and Figure 3 The vertical rib 42 is arranged along the longitudinal direction of the formwork 100, can be perpendicular to some of the main ribs 41, and is connected to the main ribs 41 and the panel 1. The horizontal rib 43 is arranged along the transverse direction of the formwork 100, is perpendicular to the vertical rib 42, and is connected to the vertical rib 42 and the panel 1. The vertical rib 42 forms an integral structure with the adjacent support rib (other vertical rib 41 or horizontal rib 42), and can transmit the load received to the back rib 2.

[0043] Optionally, as shown in Figure 4 The main rib 41 and the back rib 2 can be connected by a first connecting piece. The first connecting piece includes a J-shaped piece 51 and a bolt 52. The main rib 41 has a through hole, and the first connecting piece is connected to the main rib 41 through the through hole by the side of the J-shaped piece 51 with a hook and is fixedly connected to the back rib 2 by the bolt 52 on the other side. The first connecting piece provided by the embodiment of the present disclosure realizes the connection between the main rib 41 and the back rib 2, and the hook part of the J-shaped piece 51 is inserted into the through hole and then is pulled out to complete the cooperation with the main rib 41. The cooperation of the J-shaped piece 51 and the through hole of the main rib 41 can effectively improve the installation efficiency. The back rib 2 can also have a through hole, and the other side of the J-shaped piece 51 can be fixed by the bolt 52 after passing through the through hole of the back rib 2. The cooperation of the bolt 52 and the J-shaped piece 51 can provide flexibility in the application position of the first connecting piece. As an example, the distance between some of the main ribs 41 and the back rib 2 in the formwork 100 is different, and the cooperation of the J-shaped piece 51 and the bolt 52 can flexibly adapt to different distances.

[0044] Optionally, the support structure comprises several channel steels and second connecting members, the second connecting members can be used to connect the channel steels arranged along the longitudinal direction and / or the transverse direction of the formwork 100. Exemplarily, the second connecting members can comprise longitudinal flanges 61 and transverse flanges 62, the channel steels can comprise vertical ribs 42 and horizontal ribs 43, the longitudinal flanges 61 can be used to connect the vertical ribs 42 arranged along the longitudinal direction of the formwork 100, and the transverse flanges 62 can be used to connect the horizontal ribs 43 arranged along the transverse direction of the formwork 100, as shown in Figure 2 and Figure 3 .

[0045] Optionally, the face plate 1 can be made of stainless steel plate, the stainless steel face plate 1 can make the surface of the pier body more glossy and improve the flatness of the pier structure.

[0046] Optionally, the formwork 100 further comprises a rib plate 11, the rib plate 11 can be arranged on the side of the face plate 1 away from the concrete, as shown in Figure 2 The arrangement of the rib plate 11 can be used to reinforce the face plate 1 and prevent the face plate 1 from deforming when the concrete is poured. Exemplarily, the rib plate 11 can be welded or bolted to the back of the face plate 1 to form a stable support structure. In an example, the face plate 1 is made of stainless steel with a thickness of 8mm, 6mm, a length of 3110mm and a width of 2250mm; accordingly, the rib plate 11 can be made of flat steel with a size of 100*10mm.
