The truss 2 includes a base frame 2-1 and a plurality of right-angled triangular trusses 2-2 arranged vertically at intervals along the length direction of the base frame 2-1. The base frame 2-1 is a rectangular frame structure, which includes connected crossbeams and longitudinal beams, and the crossbeams and longitudinal beams are both made of section steel (such as channel steel). The right-angled triangular truss 2-2 is made of section steel, one of the right-angled sides of the right-angled triangular truss 2-2 is connected to the upper part of the base frame 2-1, and the other right-angled side of the right-angled triangular truss 2-2 forms the vertical side of the truss 2, and each right-angled triangular truss 2-2 is connected to form a whole through a connecting rib 10. The steel formwork 1 is arranged vertically, and its back is connected to the vertical side of the truss 2. The bottom of the chassis 2-1 is provided with at least two rows of hydraulic bottom supports 3 along its length direction, and each row of hydraulic bottom supports 3 includes a plurality of hydraulic bottom supports 3. The hydraulic bottom supports 3 are prior art, as shown in the attached Figure 5 As shown, the upper part of the hydraulic support 3 is connected to the bottom of the chassis 2-1 by bolts. Under the action of the hydraulic cylinder, the lower support can be extended or retracted. In order to ensure working reliability and safety, the hydraulic support is equipped with a locking device. Two rows of spiral adjustment supports 5 are arranged at the bottom of the chassis 2-1 along its length direction. Each row of spiral adjustment supports 5 includes a plurality of spiral adjustment supports 5. The spacing between the two rows of spiral adjustment supports 5 corresponds to the spacing between the two tracks 4 of the running system. The spiral adjustment supports 5 are prior art, as shown in the attached Figure 6 As shown, the spiral adjustment base 5 is threadedly connected to the base frame 2-1, and the base frame can be adjusted horizontally by the spiral adjustment base 5. Two rows of running wheels 8 are arranged at the bottom of the base frame 2-1, and the spacing between the two rows of running wheels 8 corresponds to the spacing between the two tracks 4 of the running system. The running wheels 8 are connected to the bottom of the base frame 2-1 through a connecting plate 11. The running wheels 8 are connected to an electric drive device 12, which is a prior art. The electric drive device 12 can drive the running wheels 8 to move along the track 4. In this embodiment, the running wheels 8 are arranged in four.

[0019] The present invention is applicable to the construction of long and continuous vertical wall concrete such as subway stations. When the present invention is used for vertical wall concrete pouring construction, the fine rolled threaded steel bar should be pre-embedded at the lower chamfer position when the bottom plate concrete is poured, so as to be used for the later reinforcement template. The track 4 is pre-embedded on the bottom plate, and the two tracks 4 are fixed by drilling holes and setting steel bar heads on the bottom plate. The installation is carried out step by step according to the principle of from bottom to top. The walking system and the bottom frame are installed first, and then the hydraulic bottom support and the spiral adjustment bottom support are installed and leveled. Among them, two rows of spiral adjustment bottom supports 5 fall on the two tracks 4, and the hydraulic bottom support 3 falls on the bottom plate that has been poured. Then the right-angled triangular truss on the upper part of the bottom frame is installed, and the right-angled triangular trusses are connected to form a whole through connecting ribs, and then the steel template 1 is fixed to the vertical side of the truss 2 in blocks. The template installation position should be consistent with the designed wall position, and the template is connected and fixed with the pre-embedded fine rolled threaded steel bar at the lower chamfer position. In order to ensure the overall stability, a reinforcement rod 7 can also be set between the truss and the bottom plate for reinforcement. According to the height of the vertical wall and the design of the truss, a counterweight can be set at the bottom of the truss to maintain the overall balance. The steel formwork and truss must be reinforced with the existing wall and bottom plate through steel bars, tie rods, etc. After the installation is completed and the inspection is passed, the concrete pouring operation can begin.

[0020] After the concrete reaches the requirements for demolding, the hydraulic bottom support and the spiral adjustment bottom support are folded up, the embedded parts are disconnected, and then the horizontal jack and the horizontal slideway set at the bottom of the truss are used to achieve a certain degree of horizontal movement and demolding. The mold can be closed by reverse operation during the next construction process. After the truss is moved horizontally, the running wheels at the bottom of the truss are aligned with the track of the running system, the hydraulic bottom support is lowered, the running wheels are lowered, the running wheels correspond to the track, the hydraulic bottom support is folded up to make the running wheels fall on the track, and the running wheels are driven by the electric drive device connected to the running wheels to move longitudinally along the track to enter the next cycle of construction.

[0021] The support system formed by the present invention is relatively fixed and safe to construct. The present invention takes about 3 days to assemble, and after the assembly is completed, a cycle of 3 days can be basically achieved, the construction efficiency is greatly improved, the construction progress can be accelerated, the construction period can be shortened, and the present invention can be used in a turnover manner, and the investment of manpower and hoisting equipment is reduced during the turnover process, which can save construction costs.
