Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, and more specifically to a support frame suitable for installing tie rods in a grid frame or a grid shell. Background Art

[0002] During the installation of tie rods in steel structure grids and lattice shells (all components are welded round tubes), cranes or tower cranes are often used for hoisting. Since the tie rods are all embedded on the main components, the angle and position of the components need to be adjusted continuously for installation accuracy. When the crane and tower crane are hoisting, the driver is far away from the installation location and needs to transmit signals to the command personnel. In addition, the hook wire rope is long and shakes greatly, which makes it more difficult to accurately position the tie rods and takes a long time to adjust. This not only wastes labor and machinery, but also delays the construction period. Utility Model Content

[0037] When in use, the bottom of the formed gantry is connected and fixed to the two sets of main pipe components respectively; then the lifting assembly 3 is connected and fixed to the tie rod 100, and the tie rod 100 is lifted by the lifting assembly 3 and its relative position relative to the two sets of main pipe components is adjusted. When it meets the design requirements, the two ends of the tie rod 100 are connected to the main pipe components;

[0038] Compared with the prior art, it is not necessary to use large-scale lifting equipment (crane or tower crane) for lifting, which reduces the difficulty of adjusting the tie rod 100 relative to the main component, and the connection accuracy is higher; the construction period is greatly shortened and the construction cost is reduced; compared with using large-scale lifting equipment to lift and adjust the tie rod 100, the entire device in the utility model is small, so that the distance between the lifting assembly 3 and the tie rod 100 is shorter, so that the tie rod 100 shakes less during the lifting and adjustment process, making the adjustment of the tie rod 100 more accurate;

[0039] In some possible implementations, in order to enable the L-shaped assembly 1 to be effectively fixed to the main pipe member, and to enable the formed portal frame to be installed on two sets of main pipe members with different wheelbases;

[0040] The L-shaped assembly 1 comprises an L-shaped frame 11, and a clamping member 12 installed at one end of the L-shaped frame 11 and used for clamping the main pipe component; the other end of the L-shaped frame 11 is connected to the support arm 2 and is slidably matched;

[0041] Two groups of L-shaped frames 11 are connected to the support arm 2 to form a portal frame, and clamping members 12 are respectively arranged at the bottom of the portal frame. The two groups of clamping members 12 are respectively clamped and fixed with the two groups of main pipe components, so that the portal frame can be stably installed on the two groups of main pipe components;

[0042] The two sets of L-shaped frames 11 and the support frame are slidably matched, so that the distance between the two sets of L-shaped frames 11 can be adjusted according to the length of the two sets of main pipe components and the tie rod 100. After the adjustment is in place, the support arm 2 and the two sets of L-shaped frames 11 can be fixed;

[0043] In some possible implementations, in order to make the L-shaped frame 11 have good stability;

[0044] The L-shaped frame 11 includes a cross bar 111 whose one end is connected to the support arm 2 and is slidably matched, a vertical bar 112 connected to the end of the cross bar 111 away from the support arm 2 and forming an L-shaped structure, and a diagonal brace 113 for connecting the cross bar 111 and the vertical bar 112; the end of the vertical bar 112 away from the cross bar 111 is connected to the clamping member 12.

[0045] One end of the crossbar 111 is slidably matched with the support arm 2 and the other end is vertically connected to the vertical rod 112. The diagonal brace 113 is used to connect the vertical rod 112 with the crossbar 111 correspondingly connected to the vertical rod 112 to form a stable whole; the clamping member 12 is installed at the bottom of the vertical rod 112 (the end of the vertical rod 112 away from the crossbar 111); when adjusting the distance according to the tie rod 100 and the two sets of main pipe components, the crossbar 111 can be moved along the length direction of the crossbar 111. After the distance is adjusted to the right position, the support arm 2 and the crossbar 111 are connected and fixed to ensure that the adjusted gantry is a stable whole;

[0046] In some possible implementations, in order to effectively realize the sliding cooperation between the L-shaped frame 11 and the support arm 2, the relative positions of the two groups of L-shaped components 1 are adjusted to meet the installation of two groups of main components with different wheelbases;

[0047] The support arm 2 is a tubular structure, the cross bar 111 is sleeved inside the support arm 2 and is coaxially arranged with the support arm 2, a plurality of through holes are respectively arranged on the support arm 2 and the cross bar 111 along their axial directions, and the support arm 2 and the cross bar 111 are fixed by bolts and through holes;

[0048] The support arm 2 is sleeved on the outside of the cross bar 111, and the two sets of cross bars 111 are close to each other and extend into the support arm 2 at one end. When adjusting, the two sets of cross bars 111 can be slid along the axis of the support arm 2; through holes are respectively provided on the support arm 2 and the cross bar 111, so that the support arm 2 and the cross bar 111 can be fixed by the cooperation of the through holes and bolts after being adjusted in place;

[0051] The upper hoop 121 cooperates with the lower hoop 122 to form a clamping hoop with a clamping cavity, and the upper hoop 121 and the lower hoop 122 are locked by the locking member 123, so that the gantry frame and the main pipe component can be effectively connected and fixed;

[0052] In some possible implementations, in order to make the connection between the L-shaped frame 11 and the main pipe component more stable;

[0053] A support plate 124 is disposed on the upper hoop 121 and is coplanar with the inner side surface of the upper hoop 121 and is disposed along the length direction of the main pipe component.

[0054] The support plate 124 is arranged on the upper hoop 121. When the upper hoop 121 and the lower hoop 122 effectively clamp and fix the main pipe component, the support plate 124 will act on the top surface of the main pipe component, effectively increasing the contact area between the gantry frame and the main pipe component, making the support for the gantry frame more stable and reliable;
