Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, specifically to a device for reinforcing the internal support beams of a cooling tower. Background Technology

[0002] Our plant's generator units were put into operation in July 2011. After long-term operation, it was found that most of the concrete horizontal support beams inside the cooling tower were at risk of falling off. The falling off of these support beams would damage the water-spraying packing, affecting the heat exchange efficiency of the cooling tower and adversely impacting the power plant's economic and social benefits.

[0003] Through on-site inspection and review of design drawings, the cause of the support beam detachment was identified, and the main influencing factors were found to be the following two aspects:

[0004] 1) The design allowance for the lap joint of the support beam is relatively small.

[0005] The horizontal support beams inside the cooling tower are designed to overlap directly on the cooling tower ring beam. Due to the hyperbolic shape of the cooling tower, the inner wall near the cooling tower ring beam is inclined inward. In order to ensure the free expansion of the concrete support beam and prevent collision with the tower wall, the allowance for the overlap of the support beam is generally small.

[0006] 2) Impact of the internal environment of the cooling tower

[0007] Cooling towers operate in a high-humidity, high-salt environment for extended periods. Sulfate, chloride, and hydroxide ions in the water react with the internal components of the concrete, causing corrosion. As the concrete expands and contracts with temperature changes, it reaches its internal stress limit and begins to deteriorate. The small overlap area of ​​the support beams leads to concentrated stress, resulting in cracking and pulverization of the concrete. Utility Model Content

[0008] The technical problem to be solved by this utility model is how to provide a reinforcement device to solve the technical problem of support beams being prone to falling off.

[0009] This utility model solves the above-mentioned technical problems through the following technical means:

[0010] This utility model provides a device for reinforcing the internal support beam of a cooling tower, including left and right symmetrical clamping members and fixing members for fixing the clamping members. The clamping members include a support member and a hanging lug connected to the support member.

[0011] Beneficial effects: This utility model uses clamping components to clamp the support beam, and uses fixing components to fix the clamping components. The clamping components clamp and fix the support beam through the support components. It is built on the ring beam by the hanging lugs, which increases the contact area of ​​the support beam on the ring beam, while ensuring that it does not collide with the tower wall. This not only solves the problems of insufficient overlap length of the support beam, small force-bearing area, and large shear stress, but also ensures the free expansion of the support beam in the horizontal direction, avoiding the situation of concrete support beam damage and falling off during long-term operation.

[0012] Preferably, the support includes a fixing plate, and one side of the fixing plate is provided with upper and lower clamping plates, both of which are fixed to the side of the fixing plate by triangular plates.

[0014] Preferably, a reinforcing member is provided on the other side of the fixing plate, and the reinforcing member is fixed on both sides and the side of the fixing plate respectively.

[0015] Beneficial effects: This utility model strengthens the fixing plate by reinforcing the fastener, so that the support member can better clamp the support beam.

[0016] Preferably, the fixing plate is rectangular or trapezoidal in shape.

[0017] Preferably, when the fixing plate is trapezoidal, the longer side of the trapezoid is the top side, and the shorter side is the bottom side.

[0018] Preferably, the ear-hanging component includes a connecting plate, with a pad at the bottom of the connecting plate, and the height of the connecting plate is less than the height of the fixing plate.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0028] according to Figure 1-2 As shown, this embodiment provides a reinforcement device for the internal support beam of a cooling tower, including symmetrical clamping components and fixing components that fix the clamping components to both sides of the support beam. The clamping components include support components and hanging lugs connected to the support components. One end of the support beam is reinforced by the support components, eliminating the risk of the support beam falling off. The hanging lugs are then used to bring the support beam into contact with the ring beam, increasing the construction area. This not only solves the problems of insufficient overlap length, small bearing area, and large shear stress of the support beam, but also ensures the free expansion of the support beam in the horizontal direction, avoiding the situation of concrete support beam damage and falling off during long-term operation.

[0029] like Figure 1As shown, the support includes a fixed plate 10, which is trapezoidal in shape, with its top edge longer than its bottom edge. Upper and lower clamping plates are provided on one side of the fixed plate 10. The upper clamping plate 11 is fixed near the top edge, and the lower clamping plate 12 is fixed near the bottom edge. The distance between the upper clamping plate 11 and the lower clamping plate 12 is exactly the height of the support beam. The upper and lower clamping plates are fixed to the side of the fixed plate 10 by triangular plates 13. A reinforcing member 16 is provided on the other side of the fixed plate 10. The reinforcing member 16 is fixed to both sides of the fixed plate 10, and a reinforcing plate 16 is fixed in the middle of the fixed plate 10. The reinforcing plate 16 is fixed to the side of the fixed plate 10 by welding. The reinforcing member 16 strengthens the fixed plate 10, allowing the support to better clamp the support beam.

[0030] The lug includes a connecting plate 14, which is triangular in shape. Its apex is aligned with and fixed to the side of the fixing plate 10. The height of the connecting plate 14 is lower than that of the fixing plate 10. A pad 15 is provided at the bottom of the connecting plate 14. The plate 15 is used to fix the lug to the ring beam. This solves the problems of insufficient overlap length of the support beam, small bearing area, and large shear stress. It also ensures the free expansion of the support beam in the horizontal direction and avoids the situation of concrete support beam breaking and falling off during long-term operation.

[0031] The fastener is a fastening bolt 17, which fixes the symmetrical clamping parts to both sides of the support beam. Three fastening bolts 17 are used above the support beam, and two fastening bolts 17 are used below it.

[0032] The working principle of the internal support beam reinforcement device for the cooling tower in this embodiment is as follows:

[0033] 1. Measure the data of the end of the support beam and the overlapping ring beam, and determine the dimensions of the fixing plate 10 and the connecting plate 14 based on the data. In this embodiment, the fixing plate 10 is trapezoidal in shape, with a top edge of 400mm, a bottom edge of 250mm, and a height of 600mm. The connecting plate 14 is triangular in shape, with a bottom edge of 250mm and a height of 400mm. Connect them together to form a reinforcement device for the internal support beam of the cooling tower.

[0034] 2. The support beam is supported by jacks, and then the symmetrically arranged clamps are fixed on both sides of the end of the support beam. The clamps are then fixed with fastening bolts. At this point, the jacks are removed, and the hanging lugs are placed on the ring beam to increase the contact area of ​​the support beam on the ring beam, while ensuring that it does not collide with the tower wall. This solves the problems of insufficient overlap length of the support beam, small bearing area, and large shear stress, and also ensures the free expansion of the support beam in the horizontal direction, avoiding the situation of concrete support beam breaking and falling off during long-term operation.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
