Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a continuous beam end formwork reinforcement structure and a construction method thereof. Background Art

[0002] During the reinforcement construction of the continuous beam end formwork, it is common to encounter welding damage to the main beam reinforcement and steel formwork surface due to formwork reinforcement problems, low efficiency in reinforcement and removal of formwork, low efficiency in recycling steel bars and steel sections used for reinforcement formwork, and various reinforcement styles, which lead to inconsistencies with the plan and briefing and final rework. At present, the engineering industry has no targeted formwork design method for this, and the conventional process has the following main defects:

[0003] (1) Reinforcement usually uses steel bars or steel sections. The steel bars or steel sections must be welded to the main bars of the beam and the steel formwork surface, and must be cut off when dismantling. Welding and cutting will cause great damage to the main bars of the beam, and cause welding damage to the steel formwork surface, which will damage the quality of the beam and increase the workload of repairing the steel formwork surface.

[0004] (2) The reinforcement welding efficiency is low, and the reinforced steel bars and steel sections cannot be recycled after being cut off, resulting in a large amount of reinforcement auxiliary construction materials being wasted, resulting in increased construction costs.

[0005] (3) The various reinforcement methods lead to inconsistencies with the plan and the reinforcement methods given in the briefing. The reinforcement quality cannot be guaranteed and the concrete pouring process is prone to mold slippage, causing quality and safety hazards. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects of the prior art and provide a continuous beam end formwork reinforcement structure and a construction method thereof, so as to solve the problem that the reinforcement method of the continuous beam end formwork is not considered in the existing continuous beam formwork reinforcement design, which is easy to weld the main reinforcement of the beam body and damage the steel formwork panel, and the connection quality cannot be guaranteed, which is easy to cause formwork slippage and cause safety accidents.

[0008] In a continuous beam end formwork reinforcement structure of the present invention, a mesh connection formed by a plurality of reinforcement pipes and a plurality of support members in a vertical and horizontal manner is used to ensure the reinforcement quality of the end formwork surface, and a limit assembly is used to ensure a stable connection between the support members and the main reinforcement. There are no welding connection points on the main reinforcement and the steel formwork panel, thereby improving the reinforcement quality of the continuous beam end formwork. The structure is quick to install and disassemble, can be recycled, further improves work efficiency, and reduces costs.

[0009] A further improvement of the continuous beam end formwork reinforcement structure of the present invention is that both ends of the support member are provided with slots for the main reinforcement to pass through.

[0010] A further improvement of the continuous beam end template reinforcement structure of the present invention is that a plurality of the reinforcement tubes are arranged in parallel.

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] See also Figure 1 , showing a front view of a continuous beam end template 20 reinforcement structure of the present invention. The present invention provides a continuous beam end template 20 reinforcement structure, comprising: a plurality of reinforcement tubes 10, the plurality of reinforcement tubes 10 are arranged at intervals on the outer wall of the continuous beam end template 20, and the reinforcement tubes 10 are arranged between the main bars 21 of the continuous beam.

[0022] Among them, multiple reinforcement tubes 10 are arranged along the length direction of the end template 20. The length of the reinforcement tube 10 corresponds to the length of the end template 20. The reinforcement tube 10 can be made of steel pipe, which has low cost. The reinforcement tube 10 is connected to the template by spot welding to facilitate subsequent dismantling.

[0023] A plurality of support members 11 are arranged on the outside of the reinforcing tube 10 , each support member 11 spans across the plurality of reinforcing tubes 10 and is connected to each reinforcing tube 10 , and main ribs 21 pass through both side ends of the support members 11 .

[0024] Among them, the support member 11 is made of channel steel and is easy to obtain. The support member 11 is arranged along the width direction of the end head template 20. The length of the support member 11 is greater than the distance between the main reinforcements 21 on both sides and is less than or equal to the width of the end head template 20.

[0025] A plurality of limiting components 12 are respectively arranged at the ends of both sides of the support member 11 , and the limiting components 12 clamp the ends of the support member 11 and the main reinforcement 21 for limiting.

[0026] Among them, the limiting component 12 is arranged on the outside of the support member 11, and the limiting component 12 limits the ends on both sides of the support member 11 to prevent the support member 11 from shifting and causing insufficient supporting force on the reinforcement pipe 10, resulting in the end template 20 being easily offset.

[0027] In this embodiment, the number of support members 11 and reinforcing tubes 10 can be increased or decreased according to the end height and web width of different continuous beams, so that the end template 20 can be most strongly supported.

[0028] In this embodiment, the connection between the support member 11 and the main rib 21 further provides support force for the reinforcement tube 10, ensuring that the support member 11 and the reinforcement tube 10 support the end template 20, making the position of the end template 20 difficult to move.

[0029] See also Figure 1 , showing a front view of a continuous beam end template 20 reinforcement structure of the present invention. The present invention provides a continuous beam end template 20 reinforcement structure, and both side ends of the support member 11 are provided with slots 13 for the main reinforcement 21 to pass through.

[0030] Among them, the slots 13 on both sides of the support member 11 are relative to each other, and the opening directions of the slots 13 on both sides are opposite. The width of the slot 13 is larger than the diameter of the main reinforcement 21, and the error can be allowed. The extension direction of the slot 13 is consistent with the length direction of the support member 11, which is convenient for installation during construction.

[0031] See also Figure 1 , showing a front view of a continuous beam end template 20 reinforcement structure of the present invention. The present invention provides a continuous beam end template 20 reinforcement structure, wherein a plurality of reinforcement tubes 10 are arranged in parallel.

[0032] Among them, the spacing between adjacent reinforcement pipes 10 is equal, so that the force on the end template 20 is uniform. The spacing is set according to the actual load-bearing requirements and is not specifically limited here.

[0040] The buckle 122 is arranged on the outer side of the end of the support member 11 , and the buckle 122 is buckled on the outer side of the main rib 21 and the connecting rod 121 .

[0041] The buckle 122 restricts the support member 11 at the connection point with the main reinforcement 21 , thus having a limiting effect.

[0042] In this embodiment, two buckles 122 are stacked and buckled in opposite directions to each other, which further strengthens the clamping effect of the buckles 122 on the main rib 21 and the support member 11.
