Description

Technical Field

[0001] The invention relates to a spherical grid construction technology, in particular to a spherical grid deflection adjustment support and a spherical grid deflection adjustment construction method. Background Art

[0002] According to the Technical Code for Spatial Grid Structures (JGJ 7-2010), the construction methods for installing space grids are divided into: high-altitude bulk method, strip or block installation method, sliding method, overall hoisting method, overall lifting method, overall jacking method, and folding and unfolding overall lifting method. In the process of installing and constructing space grids, the "high-altitude bulk method" is more commonly used. This method has the advantages of fast construction speed, safety, high efficiency, and simple operation. However, during the construction process, as the high-altitude bulk continues to extend forward, the extended end of the grid will have serious downward deflection. If it is not corrected in time, there will be serious safety and quality hazards. The traditional correction method is to use steel pipes as temporary supports at appropriate locations, and use a fall chain at the upper end of the steel pipe to lift the upper string of the grid. The operation and adjustment are extremely inconvenient, and the safety risk is high. Or, correction is made by setting up a full-hall scaffolding. This method is time-consuming and labor-intensive, and the safety and adjustment accuracy are not high. Summary of the invention

[0008] Furthermore, a plurality of support ribs are arranged at the lower end of the outer sleeve, and the support ribs are evenly distributed around the axis of the outer sleeve and avoid the positions of the vertical long holes.

[0009] The invention also discloses a spherical grid deflection adjustment construction method, which comprises the following steps.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] like Figures 1 to 5 As shown, the spherical grid deflection adjustment support 1 of the present invention has a structure including a base 1-1, an inner sleeve 1-3, an outer sleeve 1-2, a telescopic adjustment mechanism 1-4 and a lifting part 1-5.

[0033] The base 1-1 is located at the bottom of the outer sleeve 1-2. The base 1-1 is a circular or rectangular structure. The outer sleeve 1-2 is perpendicular to the base 1-1 and is located at the center of the base 1-1. The outer sleeve 1-2 and the base 1-1 are connected by welding.

[0034] The length of the inner sleeve 1-3 is much greater than that of the outer sleeve 1-2, the lower end of the inner sleeve 1-3 is inserted into the outer sleeve 1-2, and the inner diameter of the outer sleeve 1-2 is slightly larger than the outer diameter of the inner sleeve 1-3, so that when the inner sleeve 1-3 is inserted into the outer sleeve 1-2, the inner sleeve 1-3 can slide stably in the outer sleeve 1-2.

[0035] The adjustment of the relative position between the inner sleeve 1-3 and the outer sleeve 1-2 is achieved through a telescopic adjustment mechanism 1-4, which is arranged vertically, and its two ends are respectively connected to the inner sleeve 1-3 and the outer sleeve 1-2.

[0036] A vertical long hole 1-6 is provided on the side wall of the lower end of the outer sleeve 1-2, a lower connecting portion 1-7 is connected to the side wall of the lower end of the inner sleeve 1-3, and the lower connecting portion 1-7 extends outward through the vertical long hole 1-6, and an upper connecting portion 1-8 is connected to the outer wall of the upper end of the outer sleeve 1-2, and the upper connecting portion 1-8 and the lower connecting portion 1-7 correspond to each other, and the telescopic adjustment mechanism 1-4 is located between the upper connecting portion 1-8 and the lower connecting portion 1-7, and its upper end is connected to the upper connecting portion 1-8, and its lower end is connected to the lower connecting portion 1-7. Since the position of the upper connecting portion 1-8 is fixed, the telescopic adjustment mechanism 1-4 can drive the lower connecting portion 1-7 to move up and down in the vertical long hole 1-6 by telescoping, thereby driving the inner sleeve 1-3 to move up and down.

[0037] A lifting part 1-5 is provided at the top of the inner sleeve 1-3, and the lifting part 1-5 is used to lift the node connection ball of the spherical grid. Specifically, the lifting part 1-5 includes two vertical support plates arranged in a cross shape, and an arc groove 1-11 is provided on the vertical support plate, and the radius of the arc groove 1-11 is consistent with the radius of the node connection ball of the spherical grid. The two arc grooves 1-11 on the two vertical support plates form a space capable of accommodating the spherical structure. After the node connection ball of the spherical grid is placed in the space, the connection ball can rotate in the space, and the connection ball can be prevented from detaching from the space.

[0038] Among them, the upper connecting part 1-8 and the lower connecting part 1-7 are both hanging ears, and a connecting plate 1-10 is arranged above the upper connecting part 1-8. The connecting plate 1-10 is connected to the upper part of the hanging ear, which can enhance the structural strength of the upper connecting part 1-8.

[0039] The telescopic adjustment mechanism 1-4 is a manual fall chain or an electric fall chain.

[0040] There are two vertical strip holes 1-6, which are respectively located on both sides of the outer sleeve 1-2, and there are two lower connecting parts 1-7, upper connecting parts 1-8 and telescopic adjustment mechanisms 1-4. The height of the inner sleeve 1-3 can be stably adjusted through two sets of symmetrical telescopic adjustment mechanisms 1-4.

[0041] A plurality of support ribs 1-9 are provided at the lower end of the outer sleeve 1-2. The support ribs 1-9 are evenly distributed around the axis of the outer sleeve 1-2 and avoid the positions of the vertical long holes 1-6.

[0042] The invention also discloses a spherical grid deflection adjustment construction method, which comprises the following steps.

[0043] a. Prepare several spherical grid deflection adjustment supports 1, which include a base 1-1, an inner sleeve 1-3, an outer sleeve 1-2, a telescopic adjustment mechanism 1-4 and a lifting portion 1-5. The outer sleeve 1-2 is arranged perpendicular to the base 1-1, and the lower end of the outer sleeve 1-2 is connected to the center of the base 1-1. The inner sleeve 1-3 is inserted into the outer sleeve 1-2, and the inner sleeve 1-3 and the outer sleeve 1-2 are slidably connected. A vertical long strip hole 1-6 is arranged on the side wall of the outer sleeve 1-2, and a vertical strip hole 1-6 is arranged on the inner sleeve A lower connecting portion 1-7 is provided at the lower end of the tube 1-3, and an upper connecting portion 1-8 is provided at the upper end of the outer sleeve 1-2. The lower connecting portion 1-7 corresponds to the vertical long hole 1-6 and extends outward through the vertical long hole 1-6. A telescopic adjustment mechanism 1-4 is provided between the lower connecting portion 1-7 and the upper connecting portion 1-8. The lower connecting portion 1-7 and the upper connecting portion 1-8 are moved closer to or farther away from each other through the telescopic adjustment mechanism 1-4. The lifting portion 1-5 is located at the top of the inner sleeve 1-3, and is used to lift the node connection ball of the spherical grid.

[0044] b. Make a starting grid 3 with an inverted triangle cross section on the ground, and set a starting steel column 2 at the initial position of the high-altitude bulk.

[0045] c. Set the spherical grid deflection adjustment support 1 along the high-altitude bulk direction, and determine the position and height of the spherical grid deflection adjustment support 1 based on calculation.

[0046] d. Hoist the starting grid 3 onto the starting steel column 2 and the first spherical grid deflection adjustment support 1, place the node connection ball at the bottom of the starting grid 3 in the lifting part 1-5, and place the first node connection ball above the starting grid 3 on the top of the starting steel column 2.

[0047] e. Measure the deflection of the grid and adjust the support height according to the measured data until it meets the design and specification requirements, and then weld and fix the first node connection ball above the starting grid 3 to the top of the starting steel column 2.

[0048] f. A certain length of continuous grid 4 is produced on the ground, and the spherical grid deflection adjustment support 1 is continued to be set along the high-altitude bulk direction. The position and height of the spherical grid deflection adjustment support 1 are determined according to calculations.

[0049] g. Hoist the connected grid 4 made in the previous step and place it on the newly set spherical grid deflection adjustment support 1, so that the connected grid 4 is connected to the completed grid part.

[0050] Before connection, the deflection of the grid needs to be measured again and the support height needs to be fine-tuned based on the measured data.

[0051] h. Repeat steps f and g until the grid is installed to the designed position of the steel column support 5 and then carry out the construction of the steel column support 5.

[0052] In step f, the length of the subsequent grid is the distance between three nodes, and no node connection ball is set on the side close to the initial position during production.

[0053] When the height difference of the spherical grid between two steel columns is large, it is necessary to prepare a plurality of sets of spherical grid deflection adjustment supports 1 with different initial heights.

[0054] When the height difference of the spherical grid between two steel columns is small, only two groups of spherical grid deflection adjustment supports 1 need to be prepared. When the grid is constructed, first set up one group of spherical grid deflection adjustment supports 1 for support. When the second group of spherical grid deflection adjustment supports 1 are set up along the high-altitude bulk direction, the first group of spherical grid deflection adjustment supports 1 can be evacuated and moved to the next spherical grid deflection adjustment support 1 installation position. The deflection adjustment construction of the spherical grid can be realized by using the two groups of spherical grid deflection adjustment supports 1 in reverse.

[0055] The subsequent construction operations of the spherical grid are carried out in accordance with the above steps until the construction of the entire spherical grid is completed.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments may still be modified, or some or all of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
