[0031] In this embodiment, the I-shaped structural member 2 is an integrally formed structure. The I-shaped structural members 2 can be installed on the rectangular tube 1 at different intervals and in different numbers according to the length of the rectangular tube 1 during construction and specific construction requirements.

[0032] See also Figure 3 and Figure 4 The U-shaped fixture 7 comprises a fixture body 7-1 of a U-shaped structure, a fixture connection hole 7-3 is provided in the middle of the fixture body 7-1, and two ends of the fixture body 7-1 are provided with a clamp block 7-2 which can be embedded in the clamping slot 4. The U-shaped fixture 7 is a universal connector in this back corrugation system, which can complete the connection of most parts of the entire back corrugation system.

[0033] In this embodiment, the inner surface of the slot 4 is provided with sawtooth patterns, and the outer surface of the block 7-2 is also provided with corresponding sawtooth patterns. The sawtooth pattern structure can increase the friction between the slot 4 and the block 7-2, making the connection between the parts more stable.

[0034] See 5 and Figure 6 The large female angle connector includes an arc-shaped first bend portion 8, the arc of the first bend portion 8 is 90°, and the U-shaped clamps 7 are fixedly provided at both ends of the first bend portion 8, and the U-shaped opening of the U-shaped clamp 7 faces the inner side of the arc.

[0035] See also Figure 7 and Figure 8 The small female angle connector includes an arc-shaped second bend portion 9, the arc length of the second bend portion 9 is smaller than the arc length of the first bend portion 8, the arc of the second bend portion 9 is 90°, and the U-shaped clamps 7 are fixedly provided at both ends of the second bend portion 9, and the U-shaped opening of the U-shaped clamp 7 faces the outside of the arc.

[0036] The large internal angle connector and the small internal angle connector are both designed by deformation based on the U-shaped fixture 7. The large internal angle connector and the small internal angle connector are used together to complete the support and fixation of the back rib at the internal angle.

[0037] See also Fig. 9 and Fig.10 The male angle connector includes a right angle block 10, which is a hollow structure and has a block bolt hole 11. The U-shaped fixture 7 is fixedly arranged along the extension line of a right angle side of the right angle block 10, and the U-shaped fixture 7 and the right angle block 10 are located on the opposite side of the right angle side. The fixed installation of the back rib at the male angle can be completed by the cooperation of the male angle connector and the U-shaped fixture 7.

[0038] In this embodiment, the large female angle connector, the small female angle connector and the male angle connector are all integrally formed structures, which are stronger and more durable, and can be reused through cleaning and finishing.

[0039] In this embodiment, the rectangular tube 1 is made of high-strength steel. Under the condition of achieving the same strength, the overall weight of the back-rib system is lighter and easier to construct.

[0040] The installation and use method of the present invention in construction is:

[0041] See also Fig.11 and Fig.12 , Assembly of the back corrugation body: First, connect the rectangular tube 1 and the I-shaped structural member 2 by bolts and nuts to form a single-row back corrugation monomer; then place the two groups of back corrugation monomers on the side with the I-shaped structural member opposite to each other, insert the clamping block 7-2 of the U-shaped fixture 7 into the clamping groove 4 of the two opposite groups of I-shaped structural members 2 respectively, and then pass the bolts through the fixture connection holes 7-3 of the two opposite U-shaped fixtures 7 to lock, so as to form a double-row back corrugation structure, and the combined double-row back corrugation has higher strength. The U-shaped fixture 7 can also be used to complete the linear connection between the back corrugation monomers. In this embodiment, the back corrugation system rectangular tube has a modulus of 300cm, and the length includes a variety of specifications such as 300 / 600 / 900-3000, which can meet the requirements of different templates by using them alone or in combination.

[0042] See also Fig.13 , Connection of the internal angle: Place two sets of assembled double-row back ribs vertically at the internal angle of construction to form a right angle, place the large internal angle connector on the outside of the right angle, and the blocks 7-2 at both ends of the first bend 8 are respectively inserted into the slots 4 on the outside of the double-row back ribs; place the small internal angle connector on the inside of the right angle, and the blocks 7-2 at both ends of the second bend 9 are respectively inserted into the slots 4 on the inside of the double-row back ribs, pass the bolts through the fixture connection holes 7-3 of the large internal angle connector and the small internal angle connector and tighten them with nuts. The large internal angle connector and the small internal angle connector are used together inside and outside the internal angle, and the angle can be adjusted to ensure the forming requirement of the 90° right angle of the back rib at the internal angle. In the specific construction process, in order to prevent the back rib angle at the internal angle from being unstable or not tightened in place, an oblique pull rod can be set between the mutually perpendicular back ribs, and fixed with a basket screw or the like, which plays a role in further tightening the connection.

[0043] See also Fig.14 , Connection of the external corner: Place the two sets of assembled double-row back ribs vertically at the construction external corner to form a right angle, place the two external corner connectors on the outside of the two sets of double-row back ribs respectively, set U-shaped clamps 7 at the corresponding positions on the inner sides of the double-row back ribs, clamp the right-angle block 10 with the edge of the back rib, and insert the clamping block 7-2 on the external corner connector into the clamping groove 4 of the double-row back rib. Connect and fix the external corner connector to the U-shaped clamp 7 with bolts, and then insert the tension bolts into the bolt holes 11 of the block of the two external corner connectors to lock them, so as to complete the support and fixation of the back rib at the external corner.

[0044] The square tube back rib of the present invention has a module of 300 and a length of 300 / 600 / 900-3000 and other specifications. It can meet the requirements of different templates by being used alone or in combination. There is almost no need for welding in the processing process. After the tube is cut, it can be used by combining it with connectors such as U-shaped clamps, yin and yang angle connectors. The yin and yang angles are connected, and there are fixed angle parts and diagonal rods, and the angle can be adjusted to ensure the forming requirement of 90-degree right angles. Considering the cost, the new back rib system saves the renovation cost when it is reused, and there are almost no waste and customized parts. After cleaning and counting, it can be combined again for the next project.
