Description

Technical Field

[0001] The utility model relates to the field of lattice tower crane foundation construction, in particular to a movable lattice column adjusting device. Background Art

[0002] Lattice columns are common compression-bending members in the field of building construction. Their cross-sections are generally made of steel or steel plates designed to be biaxially symmetrical or uniaxially symmetrical. Lattice system members are composed of limbs and tie members. The limbs mainly bear axial forces, and the tie members mainly resist lateral forces. By arranging the material area far from the inertia axis, the bending resistance of the member can be enhanced under the same axial resistance conditions, and materials can be saved. Due to the common construction organization arrangement in the current construction field, when the pile foundation of the lower part of the lattice column is formed, the top elevation of the lattice column is usually below the construction surface.

[0003] In the "A reusable lattice column precise positioning device" disclosed in the publication number CN110685285A, it includes a lattice column body, a steel casing, a pile foundation layer, a lattice column joint, a positioning plate and a transparent level housing. The top of the lattice column body is provided with a detachable lattice column joint. The lattice column body and the lattice column joint are both arranged in the steel casing. The upper end of the lattice column joint is provided with a detachable transparent level housing. The above device can be reused and accurately positioned, but the verticality and direction of the lattice column below the construction surface cannot be controlled, which will cause deviation and displacement, resulting in reduced accuracy of the lattice column. Summary of the invention

[0004] In order to overcome the defects in the above-mentioned prior art, a movable lattice column adjustment device is provided which has a simple structure, is convenient and practical, and is used to control the verticality and direction adjustment during the early construction of the lattice column.

[0005] The technical solution of the utility model is as follows: a movable lattice column adjustment device is assembled on the upper part of the fixed lattice column; it includes a movable lattice column, a connecting long angle steel and an adjustment and positioning assembly; the connecting long angle steel is used to connect the fixed lattice column and the movable lattice column, and the movable lattice column is composed of multiple angle steels and multiple gussets; the connecting long angle steel is connected to the inner side of the ends of the multiple angle steels; the adjustment and positioning assembly includes a rotating shaft sleeve and a fixing member; the fixing member is assembled on the connecting long angle steel through the rotating shaft sleeve, and is used to control the verticality and direction of the movable lattice column. The adjustment and positioning assembly makes it difficult for the fixing member and the movable lattice column to rotate in the horizontal direction and deviate in the vertical direction, which effectively ensures the control of the verticality and direction angle.

[0006] Preferably, the fixing member includes an abutment member and a positioning column; the abutment member is L-shaped, and the positioning column is assembled at the concave corner of the abutment member. The L-shaped abutment member can effectively prevent the movable lattice column from deflecting or rotating when subjected to external force through the interaction of its two vertical parts.

[0007] Preferably, the ends of the connecting long angle steel and the fixed lattice column are provided with fixing holes for the positioning column to pass through. The provision of the fixing holes ensures that the positioning column can be accurately aligned and inserted during assembly, simplifies the installation process, and improves the accuracy of adjustment.

[0008] Preferably, one end of the abutment piece abuts against the inner side of the connecting long angle steel, and the other end of the abutment piece is connected to the rotating shaft sleeve, thereby enhancing the stability and bearing capacity of the fixing piece, and improving the accuracy of adjustment and construction efficiency.

[0009] Preferably, at least four fixing holes are provided, which are located at the same height on the side connecting the long angle steel and the fixed lattice column. The same height ensures that the positioning column can be evenly stressed when inserted, which helps to reduce structural damage or deformation caused by local stress concentration, thereby improving the stability of the overall structure.

[0010] Preferably, the abutment member and the positioning column are an integrally formed structure, which improves the structural strength of the fixing member and simplifies the manufacturing process.

[0011] Preferably, the fixing hole is a rectangular hole with a rounded chamfer. The rounded chamfer can reduce stress concentration at the edge of the hole and improve the fatigue resistance and durability of the hole. The rectangular hole provides a larger opening area, which is convenient for installation and adjustment.

[0012] As a preferred embodiment, a pad is installed between the connecting long angle steel and the plurality of angle steels. By adding the pad, the rigidity of the region can be effectively improved, and the stability of the overall structure can be enhanced.

[0013] Preferably, the shaft sleeve and the fixing member are rigidly connected to improve the stability of the adjustment and positioning assembly.

[0014] Preferably, a plurality of gusset plates are assembled between a plurality of angle steels and are evenly arranged along the length direction of the plurality of angle steels, which can significantly improve the overall stability, bearing capacity and anti-deformation capacity of the structure.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] A movable lattice column adjustment device can achieve precise adjustment of the movable lattice column, including verticality and direction control, by adjusting the rotating shaft sleeve and fixing parts in the assembly. Traditional support or load-bearing structures often have large errors during installation, and this device can significantly reduce these errors through its flexible adjustment mechanism and improve the stability and safety of the overall structure.

[0017] Furthermore, the long angle steel is used as a connecting piece to tightly connect the fixed lattice column with the movable lattice column, ensuring the stability and reliability of the connection. This stable connection avoids safety accidents caused by loose connections. The fixing piece in the adjustment and positioning assembly is used to lock the shaft sleeve, thereby ensuring that the movable lattice column can remain stable after being adjusted in place. Structural deformation or instability caused by external forces is prevented.

[0018] Furthermore, the movable lattice column adjustment device can simplify the construction process and reduce unnecessary steps and processes, which helps to reduce construction costs and time and improve the economic benefits of the overall project.

[0019] Other features and advantages of the present invention will be disclosed in detail in the following specific implementations and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0027] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0028] like Figures 1 to 3 As shown, when the lower pile foundation of the lattice column is formed, the top elevation of the lattice column is usually located below the construction surface. In order to control the verticality and direction of the subsequent upper lattice column, a movable lattice column adjustment device is installed on the lower pile of the lattice column, that is, the upper part of the fixed lattice column 4 in the embodiment at this time; the adjustment device improves the verticality of the entire lattice column to avoid structural instability caused by construction errors.

[0029] The movable lattice column adjustment device includes a movable lattice column 1, a connecting long angle steel 2 and an adjustment and positioning assembly 3; the connecting long angle steel 2 is used to connect the fixed lattice column 4 and the movable lattice column 1, and the movable lattice column 1 is composed of multiple angle steels 11 and multiple gussets 12; the connecting long angle steel 2 is connected to the inner side of the ends of the multiple angle steels 11, and the connecting long angle steel 3 is arranged parallel to the angle steel 1; the adjustment and positioning assembly 3 includes a rotating shaft sleeve 31 and a fixing member 32; the fixing member 32 is assembled on the connecting long angle steel 2 through the rotating shaft sleeve 31, and is used to control the verticality and direction of the movable lattice column 1. By rotating and adjusting the rotating shaft sleeve 31, precise control of the movable lattice column 1 can be achieved. When the required verticality and direction are achieved, the rotating shaft sleeve 31 is locked using a fixing member to ensure the stability of the movable lattice column 1.

[0030] Multiple gussets 12 are assembled between multiple angle steels 11 and evenly arranged along the length direction of multiple angle steels 11 to ensure that the structure is balanced in force in all directions and improve stability; a pad is assembled between the long angle steel 2 and multiple angle steels 11; the main function of the pad is to increase the rigidity of the connection between the long angle steel 2 and multiple angle steels 11. Since the connection between the angle steels 11 is the weak link of the structure and is easily deformed by external forces, the rigidity of this area can be effectively improved by adding pads, thereby enhancing the stability of the overall structure.

[0031] Among them, the rotating shaft sleeve 31 and the fixing member 32 are rigidly connected, the connection method is simple and reliable, and there is no high processing requirement, which is convenient for actual operation on site; the stability of the adjustment and positioning component 3 is improved, so that when the rotating shaft sleeve 31 drives the fixing member 32 to rotate, precise control of the movable lattice column 1 is achieved.

[0032] The fixing member 32 includes an abutment member 321 and a positioning column 322; the abutment member 321 is an L-shaped structure, and the positioning column 322 is assembled at the concave corner of the abutment member 321. The precise assembly position of the positioning column 322 helps to achieve precise adjustment of the movable lattice column 1. During the adjustment process, the alignment of the positioning column 322 and the fixing hole 322-1 can be observed to determine whether the movable lattice column 1 has reached the required verticality and direction, which makes it easier to achieve fine adjustment of the movable lattice column 1 and improves the construction efficiency. The abutment member 321 and the positioning column 322 are an integrally formed structure, which reduces the risk of reduced structural strength due to loose connection or weld failure; one end of the abutment member 321 abuts against the inner side of the connecting long angle steel 2, and the other end of the abutment member 321 is connected to the rotating shaft sleeve 31. The two vertical parts of the L-shaped structure can be used to contact the corresponding parts of the connecting long angle steel 2 and the movable lattice column 1, respectively, so as to ensure that the fixing member can firmly lock the position of the movable lattice column.

[0033] The ends of the connecting long angle steel 2 and the fixed lattice column 4 are provided with fixing holes 322-1 for the positioning column 322 to pass through. The setting of the fixing hole 322-1 ensures that the positioning column 322 can be accurately aligned and inserted during assembly. This precise alignment not only simplifies the installation process, but also improves the accuracy of adjustment. Workers can more easily achieve precise position control of the movable lattice column by observing and adjusting the alignment of the positioning column and the fixing hole. There are at least 4 fixing holes 322-1. This multi-point fixing method significantly enhances the connection strength, making the movable lattice column more stable when subjected to external forces, and not prone to displacement or falling off; they are respectively located on the sides of the same height of the connecting long angle steel 2 and the fixed lattice column 4, ensuring that the positioning column can be evenly stressed when inserted. This uniform force distribution helps to reduce structural damage or deformation caused by local stress concentration, thereby improving the stability of the overall structure.

[0034] Furthermore, the fixing hole 322-1 is a rectangular hole with a rounded chamfer, which provides a larger opening area, making it easier for workers to assemble; the rounded chamfer can reduce stress concentration at the edge of the hole, and improve the fatigue resistance and durability of the hole. During the installation process, the positioning column 322 in the adjustment and positioning assembly 3 and the movable lattice column 1 are not prone to horizontal angular rotation and vertical position deviation, effectively ensuring the control of verticality and direction angle, and facilitating partial recycling of the fixing parts after use, meeting the requirements of green environmental protection.

[0035] The specific operation includes the following steps:

[0036] Step 1: hoist the movable lattice column adjustment device above the fixed lattice column 4, slowly lower it to extend the connecting long angle steel 2 into the inner side of the ends of the plurality of angle steels 11 until the fixed lattice column 4 and the movable lattice column 1 are connected.

[0037] Step 2: Install the adjustment positioning assembly 3. One end of the abutment 321 abuts against the inner side of the connecting long angle steel 2. The other end of the abutment 321 is connected to the shaft sleeve 31. The positioning column 322 is fixed in the fixing hole 322-1. The verticality and direction of the movable lattice column 1 are adjusted through the shaft sleeve 31.

[0038] Step 3: Weld the suspension rod on the movable lattice column 1, lift it 20mm-30mm, let it stand for 2 minutes, and observe the overall stability.

[0039] Step 4: After confirming that the stability is reliable, lower the movable lattice column 1 to the design elevation and adjust the movable lattice column 1.

[0040] Step 5: After measurement and verification, and continuous adjustment until the error is less than the specification requirement, the movable lattice column 1 is fixed.

[0041] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
