Description

Technical Field

[0001] The utility model belongs to the field of building construction, and in particular relates to a lattice column reinforcement structure and a lattice column tower crane foundation structure. Background Art

[0002] With the widespread application of steel lattice column tower crane foundations (steel lattice column tower crane: reinforced concrete cast-in-place pile foundation, lattice columns are positioned inside the piles to form a square structural tower crane support, and the exposed parts are reinforced by welding angle steel inter-column supports (horizontal and vertical supports), horizontal supports: horizontal supports are set on the four sides of the structure to close the structure, and the middle horizontal scissors-bracing connection is made in the middle; vertical supports: vertical scissors-bracing connections are set on the four sides of the structure to form a whole.), due to the influence of various uncertain factors such as geology, construction environment, construction methods, and personnel operation, various new problems will arise during construction. For example, after the lattice column and the steel cage are overlapped at the lower hole, the lattice column will be affected by various factors and will rotate at multiple angles in the original horizontal direction, resulting in abnormal phenomena such as the four lattice columns not being able to be regularly positioned (the four sides are not arranged in the same direction), resulting in the inability to connect the inter-column supports and the lattice columns normally. Therefore, a new solution needs to be proposed to address this abnormal phenomenon. Utility Model Content

[0003] The purpose of the utility model is to overcome the defects in the prior art and provide a lattice column reinforcement structure and a lattice column tower crane foundation structure.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0005] A lattice column reinforcement structure includes a horizontal reinforcement structure and a vertical reinforcement structure; the horizontal reinforcement structure is at least two layers of horizontal flanges arranged up and down around the lattice column; the vertical reinforcement structure includes a plurality of vertical connecting plates connecting two adjacent layers of the horizontal flanges.

[0006] The cross-sectional size of the lattice column is 450*450mm; the horizontal flange is circular with a diameter of 900-1000mm and a thickness of 10-20mm.

[0007] The number of the vertical connecting plates is ≥8; the thickness of the vertical connecting plates is 10-20 mm.

[0008] The horizontal flange is connected to the lattice column and the vertical connecting plate independently by welding; the vertical connecting plate is connected to the lattice column by welding.

[0009] The utility model also includes a lattice column tower crane foundation structure, which includes four lattice columns, and horizontal supports and scissors braces connecting adjacent lattice columns; the horizontal supports and scissors braces are connected to the lattice columns through the lattice column reinforcement structure.

[0010] The horizontal support is connected to the horizontal flange; the scissors support is connected to the vertical connecting plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The technical solution of the present invention sets up a lattice column reinforcement structure at the node where the supports between the lattice columns are connected. The horizontal support and the scissors brace are directly connected to the horizontal flange or the vertical connecting plate through the horizontal flange and the vertical connecting plate. This solves the connection difficulty problem caused by the torsion of the steel lattice column, ensures the normal installation of the inter-column support reinforcement, and realizes the integrity of the steel lattice column tower crane.

[0015] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and the best embodiment.

[0016] Figure 1 A lattice column reinforcement structure is shown, including a horizontal reinforcement structure and a vertical reinforcement structure; the horizontal reinforcement structure is at least two layers of horizontal flanges 3 arranged up and down around the lattice column 1; the vertical reinforcement structure includes multiple vertical connecting plates 2 connecting two adjacent layers of the horizontal flanges.

[0017] As one embodiment, the cross-sectional size of the lattice column is 450*450mm; the horizontal flange is circular with a diameter of 900-1000mm, and as a preferred embodiment, the diameter is 950mm. Figure 1 As shown in FIG, the thickness of the horizontal flange is 10-20 mm, and as a preferred form, the thickness is 16 mm.

[0018] The number of the vertical connecting plates is ≥8; preferably 8 (if the welding angle of the column supports is inappropriate, additional vertical connecting plates can be added to connect with the supports). The thickness of the vertical connecting plates is 10-20 mm, and as the preferred form, the thickness is 16 mm; the size of the vertical connecting plates is 580*200*16 mm.

[0019] The horizontal flange is independently connected to the lattice column and the vertical connecting plate; the vertical connecting plate is welded to the lattice column; the vertical connecting plates are arranged as evenly as possible around the lattice column, and are fully welded to the horizontal flange and the lattice column, with a weld height of 10mm to ensure strength.

[0020] Figure 2 A lattice column tower crane foundation structure is shown, comprising four lattice columns 1, and horizontal supports 5 and scissor braces 4 connecting adjacent lattice columns. The horizontal supports 5 and scissor braces 4 are connected to the lattice columns 1 via the lattice column reinforcement structure, specifically by welding. The total length of the weld between the horizontal flange and the horizontal support 5 is no less than 500 mm.

[0021] The horizontal support 5 is connected to the horizontal flange 3 ; the scissors support 4 is connected to the vertical connecting plate 2 .

[0022] Function of the horizontal flange: Serving as a horizontal adapter, it solves the abnormal problem that the horizontal support 5 cannot be properly connected to the lattice column due to the rotation of the lattice column.

[0023] Function of the vertical connecting plate: As a vertical adapter, it solves the abnormal problem that the scissor brace 4 cannot be properly connected to the lattice column due to the rotation of the lattice column.

[0024] The combined structure of horizontal flange and vertical connecting plate also enhances the torsional strength of the tower crane support structure and improves its ability to resist deformation.

[0025] In summary, the use of the new lattice column reinforcement structure of the present application not only increases the torsional strength, integrity, safety, and deformation resistance of the lattice column tower crane, but also achieves the effect of increasing and improving all performance of the steel lattice column tower crane.

[0026] The specific advantages are summarized as follows: 1) This reinforcement connection method has higher stress strength; 2) This reinforcement method can ignore the horizontal rotation angle of the lattice column, and is easy to construct; 3) This reinforcement method uses simple materials and has a long service life, which can save material costs; 4) It is easy to maintain daily, and the welds must be inspected for corrosion and other phenomena within the specified time, and the inclination must be checked on time; 5) It has good stability and high safety. 6) It has a simple structure, reasonable stress, convenient operation, and easy construction. It has universal applicability and can be widely promoted and used.

For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
