[0002] In modern infrastructure construction, sinking pipe tunnel is widely used in river-crossing and sea-crossing engineering due to its advantages of fast construction speed and small environmental impact. The sinking pipe tunnel is assembled by multiple prefabricated sinking pipes, and each sinking pipe is a reinforced concrete component. These components are manufactured in the prefabrication yard and then transported to the construction site for assembly. During the prefabrication of the sinking pipe, the binding of the reinforcement cage is one of the key processes.

[0003] The reinforcement cage of the sinking pipe is completed by sequentially binding the bottom plate reinforcement cage, the side wall reinforcement cage and the top plate reinforcement cage. To improve the strength and stability of the reinforcement cage, a rigid skeleton is usually installed inside the reinforcement cage. In particular, during the binding process of the side wall reinforcement cage, the outer facade reinforcement layer needs to be bound first, then the side wall skeleton in the rigid skeleton is installed, and finally the binding of the inner facade reinforcement layer is completed. However, since the outer facade reinforcement layer and the inner facade reinforcement layer of the side wall reinforcement cage are both bound through the side wall binding jig frame built on one side, the inner facade reinforcement layer is far away from the binding jig frame, and the side wall skeleton occupies a certain space between them, making the binding of the inner facade reinforcement layer extremely difficult. Workers need to operate in a narrow space, which not only increases the difficulty and labor intensity of construction, but also affects the accuracy of the reinforcement position and the firmness of the binding due to the limited operating space, and further affects the binding quality and construction efficiency.

[0029] As Figures 1 to 2 As shown in one illustrative embodiment of the utility model's side wall steel bar binding jig frame structure using rigid skeleton, the side wall steel bar binding jig frame structure using rigid skeleton includes vertically fixedly installed side wall skeleton 1, and the side wall skeleton 1 is part of rigid skeleton, located in side wall steel bar cage.

[0030] The side wall skeleton 1 has outer frame 11, and transversely arranged cross support beam 12 is welded and installed on the outer frame 11.The outer frame 11 is rectangular, and the cross support beam 12 is located in the area surrounded by the outer frame 11 on its inner side, and the outer frame 11 has two vertical beams 13 on the inner and outer sides respectively, and the two ends of the cross support beam 12 are welded and connected to the corresponding vertical beams 13.

[0031] The side wall skeleton 1 is arranged at least two along the longitudinal direction, and the footboard 2 is arranged horizontally between adjacent side wall skeletons 1, and the two ends of the footboard 2 are penetrated into the inner space of the corresponding outer frame 11 and are arranged on the corresponding cross support beam 12, so that the two cross support beams 12 support the two ends of the footboard 2 respectively, and keep the footboard 2 horizontal along the longitudinal direction.

[0032] During the binding process of the side wall steel bar cage, the outer side side wall binding jig frame 3 is used to bind the adjacent outer facade steel bar layer 4 on the inner side, and after the binding of the outer facade steel bar layer 4 is completed, the side wall skeleton 1 is fixedly installed. Because the footboard 2 is arranged between the adjacent side wall skeletons 1, the footboard 2 provides an operation platform for the workers, so that the workers can bind the inner facade steel bar layer 5 in the space of the side wall skeleton 1 in the side wall steel bar cage, which fully expands the operation space of the workers, and the horizontal steel bars 51 and vertical steel bars 52 of the inner facade steel bar layer 5 are adjacent to the footboard 2, so that the workers can be closer to the inner facade steel bar layer 5, and the workers can stand straight to bind the steel bars, or sit on the stool placed on the footboard 2 to bind the steel bars, without needing to reach in to bind the steel bars, which reduces the construction difficulty and labor intensity.

[0033] In the above exemplary embodiment, the side wall steel bar binding formwork structure using the lateral bracing beam 12 of the rigid skeleton, the scaffold is erected between the two side wall skeletons 1, which provides an operation platform for the workers, fully utilizes the space area where the rigid skeleton is located, expands the space for the workers to operate, and makes the workers operate closer to the position where the inner vertical steel bar layer 5 is located, which reduces the difficulty and labor intensity of construction, enables the workers to pay more attention to the precision and firmness of steel bar binding during construction, thereby improving the binding quality and construction efficiency of the inner vertical steel bar layer 5 binding, and solving the problem of low construction efficiency and binding quality caused by the limited space for the inner vertical steel bar layer 5 binding of the current side wall steel bar cage.

[0034] In some embodiments, the lateral bracing beams 12 are arranged at intervals from top to bottom on the outer frame 11, so as to divide the space surrounded by the outer frame 11 into a plurality of structural spaces 10. The plurality of structural spaces 10 are divided into construction spaces 101 and reinforcing spaces 102, and the diagonal of the reinforcing space 102 is welded with a diagonal bracing beam 14. There is at least one construction space 101, and the construction spaces 101 of adjacent side wall skeletons 1 are longitudinally aligned.

[0035] The diagonal bracing beam 14 is arranged obliquely, one end of which is connected to the connection point of one lateral bracing beam 12 and one side vertical beam 13, and the other end of which is connected to the connection point of the adjacent other lateral bracing beam 12 and the other side vertical beam 13, so as to support the rectangular frame structure corresponding to the reinforcing space 102, avoid deformation, and ensure the structural strength of the side wall skeleton 1.

[0036] The construction spaces 101 are longitudinally aligned, so as to form a construction channel together with the scaffolding boards 2 in the longitudinal direction. When the scaffolding boards 2 are longitudinally arranged through the plurality of side wall skeletons 1, the workers can not only perform the steel bar binding operation of the inner vertical steel bar layer 5 on the scaffolding boards 2, but also move longitudinally through the outer frame 11 via the construction spaces 101, so as to perform the binding operation at each position of the inner vertical steel bar layer 5 in the longitudinal direction.

[0037] After the binding of the inner vertical steel bar layer 5 is completed, the scaffolding boards 2 can be removed, and the diagonal bracing beams 14 are welded and installed between the opposite corners of the construction spaces 101, so as to change the construction spaces 101 into reinforcing spaces 102, ensure that each part of the side wall skeleton 1 has high stability, and ensure that the side wall skeleton 1 stably supports the side wall steel bar cage.

[0038] In some embodiments, the inclined directions of the diagonal bracing beams 14 in adjacent reinforcing spaces 102 are opposite. More specifically, when the bottom end of one diagonal bracing beam 14 is connected to the connection point of the cross bracing beam 12 and the inner side vertical beam 13, the top end of the adjacent other diagonal bracing beam 14 below is also connected to the connection point of the cross bracing beam 12 and the inner side vertical beam 13, so that the same connection point of the cross bracing beam 12 and the vertical beam 13 can be supported by two diagonal bracing beams 14, improving the reinforcing effect of the structure and the stability of the side wall framework 1.

[0039] In some embodiments, the reinforcing spaces 102 are located at the bottom of the side wall framework 1, and the construction spaces 101 are located above the reinforcing spaces 102. When the top of the side wall framework 1 supports the scaffold board 2 and leaves space for the longitudinal movement of workers, the bottom of the side wall framework 1 is a reinforcing structure with diagonal bracing beams 14 and strong structural stability, which stably supports the structure at the top of the side wall framework 1, maintains the structural stability, and thus ensures the stability of the scaffold board 2 and the safety of the inner facade steel bar binding construction.

[0040] In some embodiments, the height of the construction space 101 is greater than or equal to twice the height of the reinforcing space 102. The two cross bracing beams 12 above and below the reinforcing space 102 are close to each other, making the structure denser and stronger, ensuring the structural stability of the side wall framework 1, and at the same time ensuring that the construction space 101 has sufficient height, so that workers do not need to bend down when passing through, further reducing the work intensity, and also facilitating the passage of materials through the side wall framework 1, making the longitudinal material transportation along the scaffold board 2 smooth.

[0041] In some embodiments, the top end of the outer frame 11 is open, and a scaffold board 2 is arranged on one of the cross bracing beams 12 adjacent to the top end of the outer frame 11, i.e., the scaffold board 2 is arranged on the topmost cross bracing beam 12 of the outer frame 11, so that workers can work at a higher position without obstruction from the scaffold board 2 or other structures above, making movement and operation more convenient, not only facilitating the placement of horizontal steel bars 51, but also facilitating the positioning and placement of vertical steel bars 52, making the working mode of workers more flexible. After the inner facade steel bar layer 5 is bound, the cross bracing beam 12 is welded and installed at the top end of the outer frame 11 to seal the open part, ensuring the structural stability of the side wall framework 1.

[0042] In some embodiments, the inner and outer edges of the scaffold board 2 are attached to the inner walls of the corresponding sides of the outer frame 11, so that the two vertical beams 13 inside and outside the outer frame 11 limit the scaffold board 2 in the transverse direction, improving the stability of the scaffold board 2 and preventing the scaffold board 2 from moving transversely, which can cause workers to fall or even fall, improving the safety of construction.

[0043] In some embodiments, guardrails 6 are horizontally arranged between adjacent side wall skeletons 1, both ends of the guardrails 6 are welded and connected to the outer frames 11 of the corresponding side wall skeletons 1. The guardrails 6 have a plurality of, respectively located above the outer side edges and the inner side edges of the scaffolds 2.

[0044] The adjacent side wall skeletons 1 can be supported in the longitudinal direction by the guardrails 6, improving the stability of the side wall skeletons 1, and further improving the stability of the scaffolds 2, so that the workers can work on a stable platform. The guardrails block the passage space above the scaffolds 2 from the inside and the outside, preventing workers from falling from the front or rear side of the scaffolds 2, and improving construction safety. In addition, after the scaffolds 2 are removed, the guardrails can be retained and connected to the vertical steel bars 52 of the inner vertical steel bar layer 5, so that the side wall skeletons 1 can support the inner vertical steel bar layer 5 in a larger range through the guardrails,

[0045] In some embodiments, as shown in Figure 3 The outer frame 11 is vertically arranged inside the inner side of the vertical beam 13, and a plurality of support short rods 7 are horizontally arranged on the vertical beam 13. The plurality of support short rods 7 all extend inward, and are arranged at equal intervals from top to bottom.

[0046] The upper and lower adjacent support short rods 7 and the inner vertical beam 13 form a positioning groove structure with the opening facing the inside. When the inner vertical steel bar layer 5 is tied, the horizontal steel bars 51 of the inner vertical steel bar layer 5 can be placed in the corresponding positioning groove structure from bottom to top one by one, ensuring that the horizontal steel bars 51 are evenly arranged, so that the inner vertical steel bar layer 5 after tying has uniform steel bar distribution and uniform structural strength. In addition, the horizontal steel bars 51 are vertically supported by the support short rods 7, so that the workers only need to align and tie, without the need for supporting operation, further reducing the working strength of the workers.

[0047] In some embodiments, the outer end of the bottom plate skeleton 8 installed in the bottom plate steel cage is welded and connected to the inner side edge of the bottom of the outer frame 11, so that the side wall skeleton 1 is integrally connected with the bottom plate skeleton 8, realizing the assembly of the stiff skeleton, and at the same time enabling the side wall skeleton 1 to be vertically fixed and installed through the bottom plate skeleton 8, improving the stability of the side wall skeleton 1, and further improving its carrying capacity for the scaffold and the workers thereon, so that the workers can work stably and safely on the scaffolds 2.

[0048] Finally, it should be noted that: the embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts of each embodiment can be referred to each other.

[0049] The above examples are only used to illustrate the technical solutions of the present application and not to limit them; although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the specific embodiments of the present application can be modified or some technical features can be replaced by equivalent ones; without departing from the spirit of the technical solutions of the present application, they should be covered in the technical solution range claimed by the present application.
