Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a reinforcement structure for the over-limit verticality of lattice columns of a lattice tower crane foundation. Background Technique
[0002] The lattice tower crane foundation is one of the commonly used tower crane foundation forms. The safety of the lattice tower crane foundation determines the safety of the use of the tower crane. During the pile foundation construction stage of the lattice tower crane foundation, the verticality of the lattice column is an important control index. In actual construction, due to various uncertain factors, the situation of the lattice column tilting is inevitable. However, if the verticality of the lattice column exceeds the set limit and the vertical load cannot be guaranteed, it is a major safety hazard for the use of the tower crane.
[0003] At present, when the verticality of the lattice column exceeds the limit, the conventional solution is to reselect the location of the lattice tower crane foundation and reconstruct the lattice column. Although the solution of the existing technology can ensure the safety of the tower crane foundation, it will lead to the delay of the construction period and the increase of costs, and at the same time disrupt the construction plan. Therefore, it is necessary to provide a reinforcement structure for the over-limit verticality of the lattice column of the lattice tower crane foundation, which can solve the problems of construction period delay, cost increase and construction plan disruption caused by reselecting the location of the lattice tower crane foundation after the verticality of the lattice column exceeds the limit in the existing technology. Summary of the Invention
[0004] The purpose of the utility model is to provide a reinforcement structure for the over-limit verticality of the lattice column of the lattice tower crane foundation, which can solve the problems of construction period delay, cost increase and construction plan disruption caused by reselecting the location of the lattice tower crane foundation after the verticality of the lattice column exceeds the limit in the existing technology.
[0005] The utility model is realized as follows:
[0006] A reinforcement structure for the over-limit verticality of the lattice column of the lattice tower crane foundation includes a first reinforcement batten plate, a second reinforcement batten plate and a reinforcement angle steel; one end of the first reinforcement batten plate is lapped with the batten plate of the lattice column, and the other end of the first reinforcement batten plate extends along the inclined direction of the lattice column. A pair of first reinforcement batten plates are symmetrically arranged on both side surfaces of the lattice column; one ends of a pair of reinforcement angle steels are respectively lapped with the other ends of the pair of first reinforcement batten plates, and the second reinforcement batten plate is lapped between the other ends of the pair of reinforcement angle steels; a pair of reinforcement angle steels are vertically symmetrically arranged on the inclined side of the lattice column, and the lower ends of the pair of reinforcement angle steels are fixed on the bottom substrate or soil layer.
[0007] The first reinforcement batten plate and the second reinforcement batten plate form a reinforcement batten plate, and several reinforcement batten plates are horizontally connected between the pair of reinforcement angle steels and the lattice column respectively.
[0008] The described first reinforcement batten plate, second reinforcement batten plate and reinforcement angle steel are welded to the lattice column to form an integral structure.
[0009] There is a third spacing between one end of the described first reinforcement batten plate and the end of the angle steel of the lattice column, and there is a first spacing between the other end of the first reinforcement batten plate and the corner of the reinforcement angle steel.
[0010] There is a second spacing between the end of the described second reinforcement batten plate and the corner of the reinforcement angle steel.
[0011] Compared with the prior art, the present utility model has the following beneficial effects:
[0012] Since the present utility model is provided with a first reinforcement batten plate, a second reinforcement batten plate and a reinforcement angle steel, a pair of first reinforcement batten plates form a tie between a pair of reinforcement angle steels and the lattice column, the second reinforcement batten plate forms a tie between a pair of reinforcement angle steels, and a pair of reinforcement angle steels are arranged vertically. The horizontal force generated due to the excessive verticality of the lattice column can be transmitted through the first reinforcement batten plate and the second reinforcement batten plate. At the same time, the horizontal force and part of the vertical load are transmitted to the bottom substrate or soil layer through a pair of reinforcement angle steels, ensuring that the bearing capacity of the lattice column meets the requirements for the safe use of the tower crane, without the need to reselect the position of the tower crane foundation and reconstruct the lattice column, thereby reducing the construction cost and ensuring the normal implementation of the construction period progress and construction plan. Description of the Drawings
[0013] Figure 1 It is a plan view of the reinforcement structure for the excessive verticality of the lattice column of the lattice type tower crane foundation of the present utility model.
[0014] In the figure, 1 is the lattice column, 101 is the batten plate, 102 is the angle steel, 2 is the first reinforcement batten plate, 3 is the second reinforcement batten plate, and 4 is the reinforcement angle steel. Detailed Embodiment
[0015] The present utility model will be further described below in conjunction with the drawings and specific embodiments.
[0016] Please refer to the attached Figure 1 , a reinforcement structure for the excessive verticality of the lattice column of a lattice type tower crane foundation, including a first reinforcement batten plate 2, a second reinforcement batten plate 3 and a reinforcement angle steel 4; one end of the first reinforcement batten plate 2 is lapped with the batten plate 101 of the lattice column 1, the other end of the first reinforcement batten plate 2 extends along the inclined direction of the lattice column 1, and a pair of first reinforcement batten plates 2 are symmetrically arranged on both side surfaces of the lattice column 1; one end of a pair of reinforcement angle steels 4 is respectively lapped with the other end of a pair of first reinforcement batten plates 2, and the second reinforcement batten plate 3 is lapped between the other ends of a pair of reinforcement angle steels 4; a pair of reinforcement angle steels 4 are vertically and symmetrically arranged on the inclined side of the lattice column 1, and the lower ends of a pair of reinforcement angle steels 4 are fixed on the bottom substrate or soil layer.
[0017] Due to the over-limit verticality of the lattice column 1, that is, the lattice column 1 has a certain degree of inclination. At the inclined part, the cross-section of the lattice column 1 is increased by connecting the U-shaped reinforcement structure, which can adjust the center of gravity of the lattice column 1. The force is transmitted to the lower base plate or soil through a pair of reinforcement angle steels 4 to share part of the vertical load of the lattice column 1, so as to ensure the bearing capacity of the overall structure formed by the lattice column 1 and the reinforcement structure.
[0018] The size of the first reinforcement batten plate 2 can be adjusted adaptively according to the inclination angle of the lattice column 1 and the reinforcement requirements. The sizes of the first reinforcement batten plates 2 at different heights can be different according to the inclination situation to ensure the reliable connection between the first reinforcement batten plate 2 and the reinforcement angle steel 4. The size of the second reinforcement batten plate 3 is selected adaptively according to the spacing between a pair of reinforcement angle steels 4 to ensure the reliable connection between the second reinforcement batten plate 3 and a pair of reinforcement angle steels 4.
[0019] By using the first reinforcement batten plate 2, the second reinforcement batten plate 3 and the reinforcement angle steel 4 to reinforce the lattice column 1 and share the load, there is no need to reselect the position of the tower crane foundation, so as to reduce the construction cost while meeting the safety of the tower crane foundation and ensure the construction plan and construction period progress.
[0020] The first reinforcement batten plate 2 and the second reinforcement batten plate 3 form a reinforcement batten plate. Several reinforcement batten plates are horizontally connected between a pair of reinforcement angle steels 4 and the lattice column 1 respectively.
[0021] Several reinforcement batten plates form a connection and reinforcement between a pair of reinforcement angle steels 4 and the lattice column 1. The whole reinforcement structure is connected with the lattice column 1 as a whole, which can be used for the transmission of horizontal force and vertical load. Due to the inclination of the lattice column 1, a horizontal force will be generated when the vertical load acts on the lattice column 1, so that the horizontal force is transmitted to a pair of reinforcement angle steels 4 through the reinforcement batten plate, and then a pair of reinforcement angle steels 4 transmit the horizontal force and part of the vertical load downward to the base plate or soil layer to ensure the force safety of the lattice column 1, thus ensuring the safety of the tower crane foundation.
[0022] The first reinforcement batten plate 2, the second reinforcement batten plate 3 and the reinforcement angle steel 4 are welded to form an integral structure with the lattice column 1.
[0023] The first reinforcement batten plate 2, the second reinforcement batten plate 3 and the reinforcement angle steel 4 are integrally connected to the lattice column 1 by full welding to form a whole, ensuring the integrity of the structure and its bearing capacity.
[0024] There is a third spacing c between one end of the first reinforcement batten plate 2 and the end of the angle steel 102 of the lattice column 1, and a first spacing a between the other end of the first reinforcement batten plate 2 and the corner of the reinforcement angle steel 4.
[0025] Preferably, the width of the first spacing a can be 100 mm, and the width of the third spacing c can be 100 mm. The widths of the first spacing a and the third spacing c can also be adjusted adaptively according to the actual construction conditions.
[0026] A second spacing b is left between the end of the second reinforcing batten plate 3 and the corner of the reinforcing angle steel 4.
[0027] Preferably, the width of the second spacing b can be 100 mm, and the width of the second spacing b can also be adjusted adaptively according to the actual construction conditions.
[0028] Please refer to the appendix Figure 1 , the construction method of the present utility model is as follows:
[0029] Select a steel plate with a width of 150 mm and a thickness of 12 mm as the first reinforcing batten plate 2, select a steel plate with a width of 300 m and a thickness of 12 mm as the second reinforcing batten plate 3, and select an angle steel of L160×16 mm as the reinforcing angle steel 4.
[0030] Weld one end of a pair of first reinforcing batten plates 2 to the batten plate 101 of the lattice column 1. The lap length can be adjusted adaptively according to the actual reinforcement requirements. A third spacing c with a width of 100 mm is left between one end of the first reinforcing batten plate 2 and the end of the angle steel 102 connected to the batten plate 101.
[0031] The other ends of a pair of first reinforcing batten plates 2 extend along the inclined direction of the lattice column 1.
[0032] Weld one surface of a pair of reinforcing angle steels 4 to the other ends of a pair of first reinforcing batten plates 2 respectively. The lap length is the length of one surface of the reinforcing angle steel 4 - 100 mm, so that a first spacing a with a width of 100 mm is left between the other end of the first reinforcing batten plate 2 and the corner of the reinforcing angle steel 4.
[0033] Weld the two ends of the second reinforcing batten plate 3 to the other surfaces of a pair of reinforcing angle steels 4 respectively. The lap length is the length of the other surface of the reinforcing angle steel 4 - 100 mm. A second spacing of 100 mm is left between the end of the second reinforcing batten plate 3 and the corner of the reinforcing angle steel 4.
[0034] The vertical spacing between a pair of first reinforcing batten plates 2 and the second reinforcing batten plate 3 is set to 600 mm, so as to form several reinforcing batten plates and tie them between the reinforcing angle steel 4 and the lattice column 1. The reinforcing angle steel 4 can be set at the same height as the lattice column 1, or the height of the reinforcing angle steel 4 can be adjusted according to the actual reinforcement requirements.
[0035] The first reinforcing batten plate 2, the second reinforcing batten plate 3, the reinforcing angle steel 4 and the batten plate 101 are all welded by full welding, and the weld width is not less than 10 mm to ensure the strength of the welding joint.
[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the protection scope of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
