Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude corridors, and in particular to a positioning device suitable for high-altitude fish-belly steel corridors in old renovation projects. Background Art

[0002] With the booming construction industry and the accelerating urban development, more and more high-rise buildings with corridors are widely used in various public and commercial buildings. Double-tower buildings and even multi-tower structures are becoming more and more common, and corridors are often used to connect multiple towers. Generally speaking, the height of steel structure corridors is very high and has a large span. Large-tonnage cranes can be used in combination with tower cranes to assemble various parts. Therefore, traditional steel structure corridor construction generally adopts the method of ground assembly, overall hydraulic lifting, and high-altitude extension installation.

[0003] Although this traditional installation system of the overall climbing of the corridor has been widely used in various engineering projects, it still has the following disadvantages:

[0004] (1) Super high-rise buildings are tall and steel corridors are heavy, so ordinary lifting equipment cannot be used for the construction of super high-rise corridors.

[0005] (2) The accuracy of the overall hoisting positioning of the steel corridor is difficult to control, which is not conducive to the later installation of the steel corridor supports. In addition, the fish-belly-shaped corridor structure is wide at the top and narrow at the bottom. The traditional corridor in-place construction method is difficult to meet the installation accuracy requirements of the support nodes.

[0006] (3) For large-scale super-high-rise building interior corridors and some super-large building renovation projects involving on-site installation of high-rise corridors, the traditional installation method of overall climbing of the corridor is limited by space, and large lifting equipment cannot complete the overall lifting construction of the corridor in areas with dense traffic or inside the building.

[0029] like Figure 1-7 As shown, a positioning device for a high-altitude fish-belly steel corridor suitable for an old renovation project is used to erect a steel corridor between a base tower and a standard tower, comprising a fish-belly steel corridor 1, the fish-belly steel corridor 1 is assembled on the floor of the base tower, an erection opening is relatively arranged between the base tower and the standard tower, a guide beam 5 is extended along the erection opening direction at the extended front end of the fish-belly steel corridor 1, pulley tracks are arranged in the same direction on the floors of the base tower and the standard tower, a power device for driving the guide beam 5 to extend along the pulley track direction is arranged on the floor of the base tower, and a lifting device for keeping the guide beam 5 in a horizontally pushed-out state is arranged on the standard tower, to ensure that the pushed-out guide beam 5 is connected to the pulley track of the standard tower.

[0030] The utility model proposes a positioning device for a high-altitude fish-belly steel corridor suitable for an old-building renovation project, which is used for erecting a steel corridor between a base tower and a target tower. When in use, the fish-belly steel corridor 1 is assembled on the floor of the base tower, and the guide beam 5 is driven by the power device to extend in the direction of the pulley track and to the erection opening position of the target tower, so that the fish-belly steel corridor 1 is erected, wherein the lifting device keeps the guide beam 5 in a horizontally pushed-out state, and makes the pushed-out guide beam 5 connect with the pulley track of the target tower. The present invention assembles the steel corridor in the tower together with the positioning device, and pushes it to a predetermined position of the corridor through a power device, effectively avoiding the risks of high-altitude hoisting operations of traditional steel structure corridors, and solving the problem that the traditional overall climbing installation method of the corridor is limited by space and cannot complete the overall construction of the corridor in areas with dense buildings or in buildings of old-building renovation projects.

[0031] Specifically, as shown in the figure, the front and rear ends of the fish-belly steel corridor 1 are vertically downwardly provided with reinforcement columns 10, the guide beam 5 is horizontally arranged at the bottom side of the reinforcement columns 10 at the front end of the fish-belly steel corridor 1, and the bottom side of the reinforcement columns 10 at the rear end of the fish-belly steel corridor 1 is provided with walking rollers that cooperate with the floor rolling. The reinforcement columns 10 and walking rollers are arranged at the rear end of the fish-belly steel corridor 1, so that the fish-belly steel corridor 1 can be kept in a horizontal state while being convenient to push and extend.

[0032] Specifically, as shown in the figure, the pulley track includes a number of transmission rollers 2 that are evenly spaced and arranged in a straight line on the floors of the base tower and the standard tower. A channel steel slide groove 11 is provided on the bottom side of the guide beam 5 along its length direction. The channel steel slide groove 11 is in limited sliding cooperation with the transmission roller 2.

[0033] Specifically, as shown in the figure, the power device includes a first winch 3 arranged on the base tower floor, and the first winch 3 drives the fish-belly steel corridor 1 to perform a pushing action along the pulley track direction through a steel wire rope.

[0034] Specifically, as shown in the figure, the lifting device includes a second winch 6 arranged on the tower, and a fixed pulley 7 matched with the second winch 6, and a steel wire rope 8 is movably wound around the fixed pulley 7 and connected to the guide beam 5. When in use, as the guide beam 5 is continuously extended, the second winch 6 synchronously pulls the guide beam 5 and applies an upward force, so that the guide beam 5 maintains a horizontally pushed-out state.

[0035] Specifically, as shown in the figure, positioning steel plates 9 are provided at both ends of the fish-belly steel corridor 1, and both ends of the positioning steel plates 9 are fixedly connected to the base tower and the standard tower respectively.

[0036] Specifically, the specific implementation steps of the utility model are:

[0037] Step 1: Structural verification: Based on the construction drawing of the large-span fish-belly steel corridor, combined with the load conditions existing in the sliding process of the fish-belly steel corridor, an overall model of the fish-belly steel corridor 1, guide beam 5, and walking roller 4 is established, and the connection nodes between the guide beam 5 and the fish-belly steel corridor 1 and the stress conditions of the guide beam 5 are analyzed to verify whether the bearing capacity of the structure can meet the construction requirements.

[0038] Step 2: On the corresponding floors of the tower, the fish-belly steel corridor 1, the guide beam 5, and the walking roller 4 are assembled and connected on site. A positioning steel plate 9 is welded on the end of the steel corridor to ensure that the steel corridor reaches the position accurately. A channel steel slide 11 is welded at the lower end of the guide beam 5 to prevent the steel corridor from derailing and losing its position during the forward movement.

[0039] Step 3: According to Figure 1 The on-site surveyor accurately measured and located each point of the pulley track 2 of the towers on both sides and the installation position of the steel corridor, to ensure that after the guide beam passes through the hollow area between the towers, it accurately docks with the pulley track of the rear tower and moves forward smoothly to the installation area. After the positioning is completed, the pulley track 2 is laid on site and fixed to the floor.

[0040] Step 4: According to Figure 1 The installation device diagram shows that the pulley power device (winch) 3 is installed on the front tower, and the corridor installation lifting device 6 is installed on the rear tower. The pulley power device drives the floor pulley to rotate, thereby providing friction for the steel corridor to move forward. During the movement of the steel corridor, the corridor installation lifting device is gradually tightened, playing a certain supporting role, providing a certain safety margin for the structure, and neutralizing the downward deflection of the guide beam to ensure that the guide beam can smoothly enter the rear tower.

[0041] Step 5: The fish-belly steel corridor 1, pulled by the pulley power device (winch) 3, smoothly passes through the hollow area between the towers. According to the fixed point measured in the early stage, the steel corridor accurately reaches the installation position of the steel corridor support. After temporarily supporting the steel corridor by jack and lifting, the pulley track 2, the rear end walking roller of the fish-belly steel corridor and the guide beam 5 are removed to complete the installation of the foundation support of the steel corridor.

[0042] The installation of each component of the entire positioning system of the utility model is simple and convenient, and there is no need to assemble a tire frame for the steel beam corridor. The corridor is accurately positioned through a preset pulley track to ensure that the translation route of the steel corridor meets the accuracy requirements, and the pulley track is docked on the other side, which effectively shortens the construction period of the steel corridor, improves the safety of the steel corridor construction, and achieves good economic benefits. It effectively solves the problem that the fish belly steel corridor has an irregular structure and is difficult to move horizontally on the slide rail, and has a certain applicability to steel corridors of different structural forms.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0044] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
