DETAILED DESCRIPTION

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by this embodiment more clearly understood, this embodiment is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this embodiment and are not used to limit this embodiment.

[0034] Please also read Figures 1 to 7 Now, a suspension for rapid installation of segment beams provided in this embodiment is described. In this embodiment, a suspension for rapid installation of segment beams is provided with a plurality of groups of suspensions 1, and two adjacent suspensions 1 are connected by screws 2.

[0035] Specifically, the suspension 1 includes a suspension body 11 and two relatively arranged suspension arms 12 at the bottom of the suspension body 11. The two suspension arms 12 are used to lift the segmental beam 3 to be installed. A tensioning hole 111 is penetrated through the suspension body 11 along the installation path direction of the segmental beam 3. The two ends of the screw rod 2 are respectively inserted into the tensioning holes 111 on the two suspension bodies 11, and the two ends of the screw rod 2 are respectively connected with two bolts 21. External force drives the bolt 21 to move relative to the screw rod 2 to change the distance between two adjacent suspensions 1.

[0036] The present embodiment is a hanger for rapid installation of segmental beams, wherein a tensioning hole 111 is provided on the hanger 1, and both ends of a screw rod 2 are passed through the tensioning hole 111, and bolts 21 are provided at both ends of the screw rod 2. By changing the relative position of the bolts 21 on the screw rod 2, the spacing between the two hangers 1 is changed, thereby further realizing a rapid assembly process of the segmental beam 3, saving the process of setting a temporary tensioning seat on the segmental beam 3 in the traditional technology, and can reduce economic costs, save construction time to the greatest extent, and create benefits.

[0037] Based on the overall introduction of the above structure, a specific implementation method of the hanging for rapid installation of segment beams in this embodiment is as follows: Figure 1 and Figure 2As shown. A connecting seat 122 is provided at the top of the hanging body 11, and is connected to the external sling assembly 5 through a steel wire rope 62, so that it can be hoisted later. The cross section of the hanging body 11 is in the shape of an "I". The top of the hanging body 11 is connected to the sling assembly 5, the bottom of the hanging body 11 is connected to the segment beam 3 to be installed, and the middle part of the hanging body 11 is used to connect the top and bottom of the hanging body 11. Among them, two hanging arms 12 are relatively arranged at the bottom of the hanging body 11, and the hanging body 11 is connected to the segment beam 3 through the two hanging arms 12.

[0038] As a preferred embodiment, the boom 12 and the segment beam 3 are connected by bolts, which has good stability. Figure 3 As shown in the figure, the boom 12 includes a connecting column 121 that is passed through and fixed on the suspension body 11, and a connecting seat 122 that is arranged on the segment beam 3. When the segment beam 3 is hoisted, the connecting column 121 is assembled to the connecting seat 122 and fixed, so that the connection between the suspension 1 and the segment beam 3 can be realized.

[0039] In addition, refer to Figure 3 , Figure 5 and Figure 6 As shown in the figure, a tensioning hole 111 is provided through the middle of the hanging body 11. When installing between the two end segment beams 3, the two ends of the screw rod 2 respectively pass through the tensioning holes 111 on the two hanging bodies 11, and bolts 21 are provided at the ends of the screw rod 2 to prevent the screw rod 2 from falling.

[0040] Preferably, two tensioning holes 111 are staggered in the height direction on the same hanging body 11 to facilitate connection with the previous hanging body 1 and the next hanging body 1. To facilitate the insertion of the screw 2, the two tensioning holes 111 on the opposite sides of the two adjacent hanging bodies 11 are at the same level. In order to avoid interference between the connections of multiple hanging bodies 1 and the screw 2, such as Figure 3 As shown, two tensioning holes 111 are staggered up and down in the height direction on the same suspension body 11, so that multiple suspensions 1 can be hoisted at the same time and it is convenient for construction workers to carry out continuous construction.

[0041] Among them, it should be noted that the clearance between the tensioning hole 111 and the screw 2 is matched to facilitate the screw 2 to pass through the tensioning hole 111, and the clearance between the screw 2 and the hole wall of the tensioning hole 111 is adjusted to make the screw 2 and the hole wall of the tensioning hole 111 fit in the same direction as much as possible, thereby increasing the friction between the two and avoiding relative sliding between the screw 2 and the suspension 1.

[0042] In order to distinguish the two tensioning holes 111 and facilitate assembly, preferably, the two tensioning holes 111 on the same suspension 1 are respectively set to have diameters of 1 m and 1.6 m.

[0043] When installing the suspension 1, the screw 2 needs to be inserted into the tensioning hole 111, and the gap between the screw 2 and the wall of the tensioning hole 111 needs to be adjusted to make the screw 2 and the wall of the tensioning hole 111 fit in the same direction as much as possible, and then the screw 2 and the bolt 21 of the suspension 1 need to be tightened at a torque of T=500N·m to ensure that there is sufficient friction during lateral tensioning to prevent relative sliding between the screw 2 and the suspension 1. This design reduces the need to set a tensioning seat on the concrete block in the traditional sense, and reduces the need to set a tensioning seat for each concrete block, and can quickly perform tensioning, thereby improving overall construction efficiency.

[0051] 1. The height of the leg 41 is adjusted according to the longitudinal slope of the line, and the lateral height is adjusted by the bottom lead screw 42 according to the lateral slope to ensure that the upper part of the leg 41 is level.

[0053] 3. The entire beam is erected and ready for the next cycle of operations.

[0054] 4. The overhead crane 6 and the hoisting device hoist the segment beam 3 through the suspension 1. When installing the suspension 1, the screw rod 2 needs to be inserted into the hoisting hole, and the gap between the screw rod 2 and the wall of the tensioning hole 111 needs to be adjusted to make the screw rod 2 and the wall of the tensioning hole 111 fit in the same direction as much as possible. Then, the bolts 21 of the screw rod 2 and the suspension 1 are tightened at a torque of T = 500 N·m to ensure that there is sufficient friction during transverse tensioning to prevent relative sliding of the screw rod 2 and the suspension 1.

[0055] A segmental beam hanger of the present embodiment is provided with a hanger for rapid installation of segmental beams in the first embodiment, and a tensioning hole 111 is provided on the hanger 1 to be connected with a screw rod 2, thereby driving the segmental beam 3 to move, realizing the tensioning process of the segmental beam 3, and further realizing rapid assembly of the segmental beam 3.
