[0034] See also Figures 1 to 5 .

[0035] The sliding reinforcement structure on the temperature post-cast strip beam comprises an embedded component, a track component, a sliding component and a fixed component.

[0036] The embedded components include three first embedded screws 110 and three second embedded bolts 120. The three first embedded screws 110 and the three second embedded bolts 120 are respectively embedded in the temperature post-casting beams 500 on both sides. The ends of the first embedded screws 110 or the second embedded bolts 120 extend out of the corresponding temperature post-casting beams 500. Both the first embedded screws 110 and the second embedded bolts 120 are made of high-strength screws of φ22.

[0037] The track assembly includes a fixed plate 210 and two slide rails 220. Three fixing holes 211 are opened on the fixed plate 210 corresponding to the positions of the three first embedded screws 110. The ends of the two slide rails 220 are respectively fixedly connected to the end faces of the fixed plate 210. The two slide rails 220 span the gap between the two temperature post-casting strip beams 500. A sliding channel 221 is formed between the two slide rails 220. The slide rails 220 are made of 16 I-beams.

[0038] The sliding assembly includes three sliding blocks 310, six first sliding wheels 311 and twelve second sliding wheels 312. The three sliding blocks 310 correspond to the three second embedded bolts 120 one by one. The sliding block 310 is provided with connecting holes 313 running through the upper and lower end surfaces thereof. The two sides of the sliding block 310 cooperate with the two sliding rails 220 of the track assembly. The sliding block 310 can move along the sliding channel 221.

[0039] The six first sliding wheels 311 are arranged in groups of two, and each group of first sliding wheels 311 is respectively mounted on a plurality of sliding blocks 310, and the first sliding wheels 311 are in contact with the surface of the temperature post-casting strip beam 500. The twelve second sliding wheels 312 are arranged in groups of four by four, and each group of second sliding wheels 312 is respectively mounted on a sliding block 310, and the second sliding wheels 312 are in contact with the upper end surface of the slide rail 220 of the track assembly.

[0040] The fixing assembly includes three first fixing nuts 410 and three second fixing nuts 420. The three first fixing nuts 410 correspond to the three first embedded screws 110 one by one. The first embedded screws 110 of the embedded assembly pass through the corresponding fixing holes 211 of the fixing plate 210 and cooperate with the first fixing nuts 410. The outer diameter of the first fixing nuts 410 is larger than the aperture of the fixing holes 211 of the fixing plate 210. The first fixing nuts 410 abut against the fixing plate 210 of the track assembly.

[0041] The three second fixing nuts 420 correspond one by one to the three second embedded screws. The second embedded screws of the embedded assembly pass through the connecting holes 313 of the corresponding sliding blocks 310 of the sliding assembly and cooperate with the second fixing nuts 420. The outer diameter of the second fixing nuts 420 is larger than the aperture of the connecting holes 313 of the sliding blocks 310 (a sliding gasket is placed before the first embedded screw 110 and the second embedded screw are installed, and the nuts are installed after the gaskets are installed).

[0042] In the main structure, the common widths of the temperature casting strips are 1000mm and 800mm. No matter whether the steel bars are connected or disconnected at the post-cast strips, the beams and slabs passing through the post-cast strips will be changed from the original continuous structural system to a cantilever structural system. The steel bars configured for the beams and slabs according to the original structural system may not meet the requirements of the construction stage.

[0043] The method for reinforcing the temperature post-casting belt beam by using the sliding reinforcement structure on the temperature post-casting belt beam comprises the following steps:

[0044] Three first embedded screws 110 and three second embedded screws are respectively embedded at the top or bottom of the temperature post-casting beam 500 on both sides (the foundation beam is embedded at the top of the beam, and the standard layer is embedded at the bottom of the beam). When the concrete strength of the temperature post-casting beam 500 reaches 50% of the design strength, the fixing hole 211 of the fixing plate 210 cooperates with the first embedded screw 110, and the three second embedded bolts 120 are in the sliding channels 221 of the two sliding rails 220 (the two sliding rails 220 are parallel to the temperature post-casting beam 500), the sliding block 310 cooperates with the two sliding rails 220, and the first sliding wheel 311 contacts the surface of the temperature post-casting beam 500, so that the sliding block 310 can slide freely with the concrete contact surface of the temperature post-casting beam 500. The second sliding wheel 312 contacts the upper end surface of the slide rail 220 of the track assembly, and transmits force through the fixed plate 210 and the two slide rails 220 of the track assembly to form the temperature post-casting strip beams 500 on both sides into a whole. After the track assembly is installed, the support frame of the temperature post-casting strip formwork support system formwork can be removed.

[0045] The above is only one embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the principle of the present invention, and these should also be regarded as belonging to the protection scope of the present invention.
