Description

Technical Field

[0001] This utility model relates to a spherical space frame construction technology, specifically a spherical space frame deflection adjustment support. Background Technology

[0002] According to the "Technical Specification for Spatial Grid Structures" (JGJ 7-2010), the construction methods for installing spatial grid structures are divided into: high-altitude bulk assembly 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 spatial grid structures, the "high-altitude bulk assembly method" is more commonly used. This method has the advantages of fast construction speed, safety and efficiency, and simple operation. However, as the high-altitude bulk assembly continues to extend forward during construction, the joint end of the grid structure will experience severe sagging. If it is not corrected in time, serious safety and quality hazards will occur. The traditional correction method is to use steel pipes as temporary supports at appropriate locations and use a chain hoist to lift the upper chord of the grid structure at the top of the steel pipes. The operation and adjustment are extremely inconvenient and have high safety risks. Alternatively, the correction method is to use full-span scaffolding. This method is time-consuming and labor-intensive, and the safety and adjustment accuracy are not high. Utility Model Content

[0003] The purpose of this utility model is to provide a spherical space frame deflection adjustment support to solve the problems of inconvenient operation and poor adjustment accuracy when correcting deflection through steel pipes or full-span scaffolding during space frame construction.

[0004] This utility model is implemented as follows: A spherical space frame deflection adjustment support includes a base, an inner sleeve, an outer sleeve, a telescopic adjustment mechanism, and a lifting part. The outer sleeve is arranged perpendicular to the base, and its lower end is connected to the center of the base. The inner sleeve is inserted into the outer sleeve, and the inner sleeve and the outer sleeve are slidably connected. A vertical elongated hole is provided on the side wall of the outer sleeve. A lower connecting part is provided at the lower end of the inner sleeve, and an upper connecting part is provided at the upper end of the outer sleeve. The lower connecting part corresponds to the vertical elongated hole and extends outward through the vertical elongated hole. A telescopic adjustment mechanism is provided between the lower connecting part and the upper connecting part, which allows the lower connecting part and the upper connecting part to move closer or further apart. The lifting part is located at the top of the inner sleeve and is used to support the node connecting spheres of the spherical space frame.

[0005] Furthermore, both the upper and lower connecting parts are hooks, and the telescopic adjustment mechanism is a manual chain hoist or an electric chain hoist.

[0006] Furthermore, there are two vertical elongated holes, located on both sides of the outer sleeve, and there are two lower connecting parts, two upper connecting parts, and two telescopic adjustment mechanisms.

[0007] Furthermore, the supporting part includes two vertical support plates arranged in a cross shape, and an arc-shaped groove is provided on the vertical support plate. The radius of the arc-shaped groove is consistent with the radius of the node connecting ball of the spherical grid.

[0008] Furthermore, a number of support ribs are provided at the lower end of the outer sleeve. The support ribs are evenly distributed around the axis of the outer sleeve and avoid the position of the vertical elongated hole.

[0009] This utility model also discloses a construction method for adjusting the deflection of a spherical space frame, including the following steps.

[0010] a. Prepare several spherical space frame deflection adjustment supports. Each spherical space frame deflection adjustment support includes a base, an inner sleeve, an outer sleeve, a telescopic adjustment mechanism, and a support part. The outer sleeve is set perpendicular to the base, and its lower end is connected to the center of the base. The inner sleeve is inserted into the outer sleeve, and the inner sleeve and the outer sleeve are slidably connected. A vertical elongated hole is provided on the side wall of the outer sleeve. A lower connecting part is provided at the lower end of the inner sleeve, and an upper connecting part is provided at the upper end of the outer sleeve. The lower connecting part corresponds to the vertical elongated hole and extends outward through the vertical elongated hole. A telescopic adjustment mechanism is provided between the lower connecting part and the upper connecting part, which allows the lower connecting part and the upper connecting part to move closer or further apart. The support part is located at the top of the inner sleeve and is used to support the node connecting spheres of the spherical space frame.

[0011] b. Construct a starting space frame with an inverted triangular cross-section on the ground, and set up starting steel columns at the initial position of the bulk loading at high altitude.

[0012] c. Install spherical space frame deflection adjustment supports along the direction of high-altitude bulk loading, and determine the position and height of the spherical space frame deflection adjustment supports based on calculations.

[0013] d. Hoist the starting grid frame onto the starting steel column and the first spherical grid frame deflection adjustment support, place the node connecting ball at the bottom of the starting grid frame inside the support part, and place the first node connecting ball at the top of the starting grid frame on the top of the starting steel column.

[0014] e. Measure the deflection of the space frame, 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 connecting ball above the starting space frame to the top of the starting steel column.

[0015] f. Construct a certain length of continuous space frame on the ground, and continue to install spherical space frame deflection adjustment supports along the direction of high-altitude bulk assembly.

[0017] h. Repeat steps f and g until the space frame is installed at the designed steel column support position, and then construct the steel column support.

[0018] Furthermore, in step f, the length of the subsequent grid structure is the distance between three nodes, and no node connecting balls are set on the side closest to the initial position during construction.

[0019] Furthermore, two sets of spherical space frame deflection adjustment supports are prepared. After the second set of spherical space frame deflection adjustment supports is set along the high-altitude bulk direction, the first set of spherical space frame deflection adjustment supports can be removed and moved to the installation position of the next spherical space frame deflection adjustment support.

[0020] This invention is used in space frame installation projects to safely, quickly, and efficiently adjust the deflection generated during the high-altitude assembly of space frames. Compared with traditional adjustment methods, it increases the safety factor, reduces the operational difficulty of the construction process, and also improves the construction speed.

[0030] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] like Figures 1 to 5 As shown, the spherical grid deflection adjustment support 1 of this utility model includes 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 tube 1-2. The base 1-1 has a circular or rectangular structure. The outer tube 1-2 is perpendicular to the base 1-1 and is located at the center of the base 1-1. The outer tube 1-2 and the base 1-1 are connected by welding.

[0034] The length of the inner sleeve 1-3 is much greater than the length 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 within the outer sleeve 1-2.

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

[0036] The outer sleeve 1-2 has a vertical elongated hole 1-6 on its lower side wall. A lower connecting part 1-7 is connected to the lower side wall of the inner sleeve 1-3, extending outward through the vertical elongated hole 1-6. An upper connecting part 1-8 is connected to the upper outer wall of the outer sleeve 1-2, corresponding to the lower connecting part 1-7. A telescopic adjustment mechanism 1-4 is located between the upper connecting part 1-8 and the lower connecting part 1-7, with its upper end connected to the upper connecting part 1-8 and its lower end connected to the lower connecting part 1-7. Since the position of the upper connecting part 1-8 is fixed, the telescopic adjustment mechanism 1-4 can move the lower connecting part 1-7 up and down within the vertical elongated hole 1-6 by telescopic movement, thereby driving the inner sleeve 1-3 to move up and down.

[0037] A support part 1-5 is provided at the top of the inner sleeve 1-3. The support part 1-5 is used to support the node connecting balls of the spherical space frame. Specifically, the support part 1-5 includes two vertical support plates arranged in a cross shape. An arc-shaped groove 1-11 is provided on the vertical support plate. The radius of the arc-shaped groove 1-11 is the same as the radius of the node connecting ball of the spherical space frame. The two arc-shaped grooves 1-11 on the two vertical support plates form a space that can accommodate the spherical structure. After the node connecting ball of the spherical space frame is placed in this space, the connecting ball can rotate in this space and is prevented from falling out of the space.

[0038] The upper connecting part 1-8 and the lower connecting part 1-7 are both lugs. A connecting plate 1-10 is provided above the upper connecting part 1-8. The connecting plate 1-10 is connected to the upper part of the lug, which can strengthen the structural strength of the upper connecting part 1-8.

[0039] The telescopic adjustment mechanisms 1-4 are manual or electric chain hoists.

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

[0041] Several support ribs 1-9 are provided at the lower end of the outer tube 1-2. The support ribs 1-9 are evenly distributed around the axis of the outer tube 1-2 and avoid the position of the vertical elongated hole 1-6.

[0042] This utility model also discloses a construction method for adjusting the deflection of a spherical space frame, including the following steps.

[0043] a. Prepare several spherical space frame deflection adjustment supports 1. Each spherical space frame deflection adjustment support 1 includes 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. The outer sleeve 1-2 is perpendicular to the base 1-1, and its lower end 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 elongated hole 1-6 is provided on the side wall of the outer sleeve 1-2. The lower end of tube 1-3 is provided with a lower connecting part 1-7, and the upper end of the outer tube 1-2 is provided with an upper connecting part 1-8. The lower connecting part 1-7 corresponds to the vertical elongated hole 1-6 and extends outward through the vertical elongated hole 1-6. A telescopic adjustment mechanism 1-4 is provided between the lower connecting part 1-7 and the upper connecting part 1-8. The telescopic adjustment mechanism 1-4 makes the lower connecting part 1-7 and the upper connecting part 1-8 move closer or further apart. The lifting part 1-5 is located at the top of the inner tube 1-3 and is used to support the node connecting ball of the spherical grid.

[0044] b. Construct a starting space frame 3 with an inverted triangular cross-section on the ground, and set up starting steel columns 2 at the initial position of the bulk loading at high altitude.

[0045] c. Install spherical space frame deflection adjustment support 1 along the high-altitude bulk direction, and determine the position and height of spherical space frame deflection adjustment support 1 according to 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 connecting ball at the lower part of the starting grid 3 into the support part 1-5, and place the first node connecting ball at the top of the starting grid 3 on the top of the starting steel column 2.

[0047] e. Measure the deflection of the space frame, adjust the support height according to the measured data until the design and specification requirements are met, and then weld and fix the first node connecting ball above the starting space frame 3 to the top of the starting steel column 2.

[0048] f. Construct a certain length of continuous space frame 4 on the ground, and continue to set up spherical space frame deflection adjustment support 1 along the high-altitude bulk direction. Determine the position and height of spherical space frame deflection adjustment support 1 based on calculations.

[0049] g. Hoist the pre-made extension space frame 4 into place on the newly installed spherical space frame deflection adjustment support 1, so that the extension space frame 4 is connected to the completed space frame section.

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

[0051] h. Repeat steps f and g until the space frame is installed at 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 structure is the distance between three nodes, and no node connecting balls are set on the side closest to the initial position during construction.

[0053] When the height difference of the spherical space frame between two steel columns is large, multiple sets of spherical space frame deflection adjustment supports with different initial heights need to be prepared.

[0054] When the height difference of the spherical space frame between two steel columns is small, only two sets of spherical space frame deflection adjustment supports 1 are needed. During the construction of the space frame, one set of spherical space frame deflection adjustment supports 1 is set up first for support. After the second set of spherical space frame deflection adjustment supports 1 is set up along the high-altitude bulk direction, the first set of spherical space frame deflection adjustment supports 1 can be removed and moved to the installation position of the next spherical space frame deflection adjustment support 1. The construction of deflection adjustment of the spherical space frame can be realized by using the two sets of spherical space frame deflection adjustment supports 1 in reverse.

[0055] The subsequent construction operations of the spherical space frame shall be carried out in accordance with the above steps until the construction of the entire spherical space frame is completed.

[0056] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
