The temporary anchoring structure supports and fixes the bottom plate 21, and the insulation side plate 23 is fixed to the truss 22 by fasteners, and the insulation roof 24 is fixed to the top of the truss 22 by fasteners. The closed space surrounded by the bottom plate 21, the insulation side plate 23 and the insulation roof 24 accommodates the construction area of ​​the No. 0 block at the upper end of the pier 7 and achieves the insulation effect. The steam generator 3 and the hot air gun 4 are powered by the generator, and the construction personnel operate the steam generator 3 and the hot air gun 4 to adjust the temperature in the closed space, and control the temperature of the construction materials at an appropriate temperature, so that the No. 0 block can be constructed even when the external ambient temperature is low, ensuring the construction progress and quality of the project.

[0032] Preferably, combined Figure 1 , Figure 3 and Figure 4As shown, the fastener includes a fixing clamp and a sleeve, and the fixing clamp and the sleeve cooperate to fix the insulation side plate 23 and the insulation roof 24 on the truss 22.

Taking the fixing of the heat-insulating side panel 23 as an example, a plurality of first through holes are provided on the truss 22, and the screw rod 251 is passed through the heat-insulating side panel 23 and the first through holes in sequence and then screwed into the sleeve 261. When the screw rod 251 is screwed into a certain position, the first clamping plate 253 and the second clamping plate 263 respectively abut against the heat-insulating side panel 23 from both sides. The arrangement of the first elastic member 252 and the second elastic member 262 enables the screw rod 251 to be further screwed in, and the heat-insulating side panel 23 deforms the first elastic member 252 through the first clamping plate 253 and the second elastic member 262 through the second clamping plate 263. The elastic force generated by the first elastic member 252 and the second elastic member 262 acts on the first clamping plate 253 and the second clamping plate 263, thereby clamping the heat-insulating side panel 23.

[0033] Preferably, the first elastic member 252 is in an excellent arc shape, the screw 251 is arranged along the radial direction of the first elastic member 252, both ends of the first elastic member 252 are fixed on the first clamping plate 253, and the arc portion of the first elastic member 252 is connected to the screw 251 through a first connecting assembly.
