[0032] The reinforcement device provided by the present invention supports the circular frame column 5 through the forward reinforcement component, and supports the rectangular beam 6 through the lateral support component 2. The support frame 1 is used as the supporting body. The force points of the forward reinforcement component plus the force points of the two lateral support components 2 form a triangular force, which can maintain the balance of the support frame 1 and realize reliable reinforcement of the paper mold at the connection between the circular column and the rectangular beam 6, avoiding the occurrence of expansion mold quality defects.

[0033] On the basis of the above embodiments, the connection direction of the two lateral supporting components 2 is perpendicular to the extension direction of the positive reinforcement rotating rod 3. Figure 2 As shown, the force is more stable and the fixing effect is good.

[0035] On the basis of the above-mentioned embodiments, a slot 3-1 is fixedly provided at one end of the forward reinforcement rotary rod 3, and the forward top plate 4 is detachably installed in the slot 3-1. Specifically, the slot 3-1 can be a stainless steel slot 3-1, which is welded and fixed to the end of the forward reinforcement rotary rod 3. When the position of the forward reinforcement rotary rod 3 is adjusted to be close to the surface of the circular frame column 5, the forward top plate 4 is installed in the slot 3-1.

Figure 2 As shown, a reinforcement device is installed between every two rectangular beams 6 , and two adjacent reinforcement devices act on both sides of the rectangular beam 6 at the same time, and under the interaction, they have the effect of clamping the rectangular beam 6 .

[0042] In a specific embodiment, the reinforcement device includes four parts: a trapezoidal support frame 1, lateral top supports, a forward reinforcement rotary rod 3 and an arc-shaped top plate. During construction, the lateral top supports on both sides are screwed and extended to the wooden back ribs on both sides of the rectangular beam 6 for fixation, and then the forward reinforcement rotary rod 3 is screwed, and the paper mold at the beam-column joint is firmly tightened and fixed through the front arc-shaped top plate, thereby finally achieving the function of avoiding concrete expansion mold quality accidents at the beam-column connection.

[0043] Specifically, 1. Introduction to the functions of each component:

[0044] ① Support frame 1: The bottom rod is a 48.3mm galvanized steel pipe of national standard, the top rod and the diagonal rod are £30*30mm square steel pipes, and a hole is opened in the middle of the top rod and the bottom rod with a diameter of 25mm. Double nuts are welded on both sides of the hole to receive the positive reinforcement rotating rod 3, forming the trapezoidal main body of the device;

[0045] ② Two-side supports: modified from national standard steel pipe supports, in which the arc-shaped top plate of the supports is rotated inward 45° to better and more tightly connect and fix with the rectangular beam 6 back ribs;

[0046] ③ Positive reinforcement rotary rod 3: It is made of HRB400E steel bar with a diameter of 20mm. Specifically, the diameter of the rotary rod can be adjusted according to the actual needs such as the diameter of the cylinder and the size of the concrete side pressure of the beam-column joint;

[0047] ④ Arc-shaped top plate: According to the diameter of the column and the width of the paper template at the beam-column joint, prepare several different specifications of arc-shaped steel plates, and replace them according to actual needs.

[0048] 2. Means of implementation of the solution:

[0049] Steps to achieve a firm reinforcement of the paper model at the connection between the cylinder and the rectangular beam 6:

[0050] ① Installation of circular frame column 5 paper model, i.e. cylindrical paper model: hoist the cylindrical paper model of specified diameter and length into place according to the requirements of the design drawings;

[0051] ② Installation of rectangular beam 6 wooden formwork: According to the requirements of the design drawings, the bottom formwork of the primary and secondary beams is installed in place, and then the beam mouth is opened on the top plate of the cylindrical paper formwork according to the beam bottom elevation, and finally the side formwork of the beam is installed and reinforced;

[0052] ③ Check the position of the cylindrical paper model: Use a tape measure and plumb line to check the plane position and verticality of the cylindrical paper model. Only after the check is correct can the beam-column joint template be fixed;

[0053] ④ Beam-column joint, i.e., reinforcement of the circular frame column 5 and the rectangular beam 6: firstly, screw and extend the lateral supports on both sides to the wooden back ribs on both sides of the rectangular beam 6 for fixing, then screw the forward reinforcement rod 3, and firmly tighten and fix the paper mold at the beam-column joint through the arc-shaped top plate in front;

[0054] ⑤ Pouring concrete: first pour the concrete of the circular frame column 5, then pour the concrete of the rectangular frame beam, and pour symmetrically in layers to ensure uniform force on the formwork components;

[0055] ⑥ Formwork removal: After concrete pouring is completed, it should be cured on time. After reaching the design strength requirements, it should be removed according to the principle of first removing non-load-bearing structures and then weighing structures, first supporting structures and then removing structures, and then supporting structures and then removing structures. At the same time, attention should be paid to the protection of finished products to avoid damaging the concrete surface.

[0056] ⑦ Observation of concrete appearance: After the formwork is removed, the quality of concrete appearance molding is observed in time. The overall molding effect is good and meets the standards of fair-faced concrete.

[0057] The reinforcement device, through the overall design, is a combination of a trapezoidal main body, a lateral top support, a positive reinforcement rotary rod 3 and an arc-shaped top plate; it can achieve reliable reinforcement of the paper mold at the connection part of the column and the rectangular beam 6, and can realize the turnover use of the reinforcement parts at the connection part of the column and the rectangular beam 6, thereby reducing the project cost; at the same time, it can achieve excellent concrete molding quality at the connection part of the column and the rectangular beam 6, reaching the standard of fair-faced concrete.
