DETAILED DESCRIPTION

[0018] The following is a detailed description of the climbing material distribution system and its construction method provided by the present invention, with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clarify the purpose of illustrating the embodiments of the present invention.

[0019] Example 1 like Figure 1 As shown, during the construction of a certain super-high-rise building, the construction of the core tube 1 preceded the construction of the outer frame structure 2 by 10 floors. The outer frame structure includes giant columns 3, structural steel beams 4, and floor slabs. The construction of the structural steel beams 4 precedes the concrete pouring of the floor slabs. For construction safety, the installation of the structural steel beams and the laying of the corrugated steel sheets are usually completed on the floor above the floor where the concrete is to be poured. If a concrete placing boom were installed on the outer wall of the core tube 1, the support and climbing issues of the concrete placing boom would be resolved. However, the concrete placing boom can only spread concrete to the outside with its own position as the center, resulting in a limited coverage range. The boom section of the concrete placing boom is located above the corrugated steel sheets and needs to be bent from above to extend under the corrugated steel sheets before pouring the concrete for the floor slabs. This creates many obstacles, resulting in low construction efficiency, slow construction speed, and high costs.

[0020] The climbing material distribution system provided in this embodiment mainly considers moving the material distribution machine from the outer wall of the core tube to the outer frame structure, and solves the problems arising therefrom, such as the track setting of the material distribution machine, the structure setting and climbing of the material distribution machine, the setting of the pump pipe, and the filling of the floor plate.

[0021] Combine Figure 1 and Figure 2As shown, the climbing distribution system provided by the embodiment includes a climbing column 10, a climbing column fixing structure 20, a distribution machine 30, a climbing base 40, a pump pipe 50 and a temporary fixing support 60.

[0022] The climbing column 10 is a steel column, which provides support for the distribution machine, and is hollow, serving as a concrete transportation passage between the pump pipe and the distribution machine. The outer frame structure includes a mega column and a horizontally arranged structural steel beam, and the climbing column is connected to the structural steel beam through a plurality of climbing column fixing structures. As an example, in combination with Figures 1 to 3 As shown, the climbing column fixing structure 20 includes two temporary constraint steel beams 21 and four beam support brackets 22. The two temporary constraint steel beams are arranged side by side and spaced apart, with both ends resting on the structural steel beam and both ends bolted to the beam support bracket. The beam support bracket is fixed to the structural steel beam at the bottom. The climbing column is located between the two temporary constraint steel beams, and the two temporary constraint steel beams are connected by a set of bending moment resisting screws 23 that pass through the climbing column, completing the transfer of bending moment. Of course, the function of the climbing column fixing structure is to fixedly connect the climbing column and the structural steel beam, and other structural forms can of course be used.

[0023] The pump pipe 50 includes a vertical pump pipe for vertical transportation and a horizontal pump pipe located below the structural steel beam, with one end of the horizontal pump pipe communicating with the top of the vertical pump pipe. The pump pipe is fixed to the outer frame structure by a fixing device, such as a clamp, a bolt or a connecting rod. The vertical pump pipe pumps concrete from the ground to the target construction floor, and then transports it to the climbing column through the horizontal pump pipe. The climbing column is provided with a pump pipe fixing interface at the corresponding height, which is used to connect with the end of the horizontal pump pipe. The pump pipe fixing structure can be arranged below or above the construction floor, that is, the horizontal pump pipe can be suspended above the construction floor, or fixed to the structural steel beam of the floor above the construction floor.

[0024] As Figure 4As shown, the climbing rail column includes an upper column section 11, a lower column section 12, and a rotating section 13 located in the middle, which is rotatably connected with the upper column section and the lower column section. The rotating connection can be achieved by pump pipe rotating connection. As an example, a T-shaped slide rail 14 is arranged at the upper and lower end faces of the rotating section, and a T-shaped notch 15 is arranged on the connecting end face of the upper column section and the lower column section. The T-shaped slide rail is buckled in the T-shaped notch to achieve the rotating connection between the rotating section and the upper column section and the lower column section. Lubricating material can also be arranged in the T-shaped notch for sealing. Further, in order to improve the shear resistance and bending resistance of the climbing rail at the rotating section, the outer side wall of the upper column section and the lower column section can be thickened, and a sleeve can also be arranged. One end of the sleeve is fixedly connected with the upper column section and the lower column section, and the other end is sleeved with the end of the rotating section and rotatably buckled with the rotating section. Of course, sleeves can also be arranged at both ends of the rotating section. One end of the sleeve is fixed with the rotating section, and the other end is sleeved with the end of the upper column section and the lower column section.

[0025] In combination Figures 4 to 6 As shown, the rotating section is provided with a connecting hole 16, and one end of the distributing pipe of the distributing machine is fixed with the connecting hole 16 of the rotating section through the telescopic plug-in pump pipe 80. The telescopic plug-in pump pipe 80 includes a first pump pipe section 81, a second pump pipe section 82, a first joint 83, and a second joint 84. One end of the first pump pipe section is sleeved with one end of the second pump pipe section and can slide radially, and is sealed by a rubber sealing ring 85. The other end of the first pump pipe section is provided with the first joint, and the other end of the second pump pipe section is provided with the second joint. The first joint is used to be inserted into the connecting hole, and the second joint is used to be connected with the pump pipe of the distributing machine. The first joint 83 is detachably connected with the connecting hole 16, which can be achieved by the prior art.

[0026] In one specific embodiment, a lock hole 17 is arranged on the side wall of the connecting hole 16, and a lock tongue matched with the lock hole is arranged on the first joint. When the lock tongue is inserted into the lock hole, the first joint is locked with the rotating section. When the lock tongue is pulled out of the lock hole, the first joint is separated from the rotating section. Specifically, a cavity 831 is arranged on the side wall of the first joint 83, and a lock tongue 832 and a spring 833 are arranged in the cavity 831. The protruding end of the lock tongue is wedge-shaped. When the first joint is inserted into the connecting hole, the side wall edge of the connecting hole is opposite to the slope surface of the wedge-shaped lock tongue. Under the action of pressure, the lock tongue extrudes the spring and retracts into the cavity. When the lock tongue moves to the lock hole position, the lock tongue pops out and is inserted into the lock hole under the action of the spring force. Further, a fixed pulley 834 is arranged in the cavity, a rotating handle 86 is arranged on the first pump pipe, and the lock tongue 832 is connected with the rotating handle through a pull rope 87 passing through the fixed pulley 834. When it is needed to pull out the first joint, the rotating handle is controlled to make the pull rope pull the lock tongue to retract into the cavity, and the telescopic plug-in pump pipe is pulled out of the connecting hole.

[0027] It should be noted that the top sealing plate and the bottom sealing plate are arranged in the climbing column, so that the concrete in the horizontal pump pipe is conveyed to the connecting hole through the climbing column, and then conveyed to the placing boom pump pipe through the telescopic plug-in pump pipe to realize the concrete pouring.

[0028] The climbing base 40 is arranged on the climbing column 10 and can move up and down along the climbing column. As an example, an outer thread is arranged on the climbing column, and the climbing base is an activity sleeve provided with an inner thread. The activity sleeve is threadedly connected with the climbing column. When the climbing column is fixed, the activity sleeve can be spirally moved upward or downward along the climbing column by driving the motor. When the activity sleeve is fixed, the climbing column can be rotated and spirally moved upward or downward by driving the motor. Of course, a gear slot can be arranged on the outer wall of the climbing column to form a climbing track, and the relative movement between the climbing base and the climbing column can be realized by driving the climbing gear to rotate by the driving motor. Further, a limit stopper is arranged at the top of the climbing column. The limit stopper can place the maximum climbing position of the climbing base, so as to prevent the climbing base from falling due to climbing to the top of the climbing column.

[0029] The placing boom 30 includes a rotating base and a plurality of arm sections. The rotating base is fixedly connected with the climbing base, and the arm sections of the placing boom are connected in sequence. The first arm section is hingedly connected with the rotating base. The rotating base can rotate the first arm section, so that the first arm section can be rotated from a horizontal state to a vertical state. The first arm section can be limited by a limiting structure after being limited, so that the first arm section is limited to rotate. The rotation of the first arm section can be driven by a hydraulic cylinder or an electric motor. Of course, the arm sections of the placing boom can adopt the prior art. For example, the adjacent arm sections can be relatively rotated. The pump pipe is arranged on the arm section, and the end of the pump pipe of the tail arm section is provided with a discharge port.

[0030] The climbing placing system provided in the embodiment sets the climbing column on the structural steel beam of the outer frame structure, sets the placing boom on the climbing column, and can climb along the climbing column through the climbing base. When the placing boom is supported by the temporary fixing support, the climbing column can be lifted through the climbing base, so that the placing boom can climb by itself, and the construction efficiency is improved. Moreover, the climbing column serves as a communication channel between the placing boom and the pump pipe, so that the pump pipe is arranged below or above the construction layer, and the pump pipe is convenient to install. The placing boom mainly pours the concrete of the layer and a small amount of concrete for filling the hole of the next floor, so that the workers can always work under the protection of the profiled steel plate, and the safety risk of the structural steel beam hoisting of the profiled steel plate on the upper layer to the concrete pouring is avoided, and the construction safety is improved.

[0031] Embodiment two The embodiment provides a construction method of the climbing placing boom in the embodiment one, and the construction method comprises the following steps. Step one, as Figure 7As shown, the climbing rails are fixed to the structural steel beams of the outer frame structure through the climbing rail fixing structure. A concrete placing boom and pump pipes are installed, connecting the pump pipes, climbing rails, and placing boom to form a concrete transportation channel. The nth floor is currently under construction. The n-1th floor is in the curing stage after the concrete pouring, but there are holes on this floor that need to be filled. The structural steel beams of the n+1th floor have been hoisted and the corrugated steel sheeting has been laid.

[0032] Step 2: Figure 8 As shown, a concrete placing boom is used to lay concrete for the nth floor slab and fill in the gaps in concrete for the n-1th floor. The boom can be rotated to change the position of the discharging port. The boom can be rotated around the climbing rails by rotating the climbing base, or vice versa, by rotating the rotating base around the climbing base, thereby increasing the concrete placing boom's coverage area. Simultaneously, the structural steel beams and corrugated steel sheets for the n+2th floor can be constructed.

[0033] Step 3: Figure 9 As shown, clean the concrete placing boom, fold the boom section, and rotate the base to a vertical position. Remove the connections between the climbing rail, concrete placing boom, and pump pipe. By moving the climbing base relative to the climbing rail, the concrete placing boom ascends to the n+1 floor. The climbing base is equipped with a drive motor. When the climbing rail is fixed, the drive motor rotates forward, causing the climbing base to climb up along the climbing rail, thereby raising the concrete placing boom one floor.

[0034] Step 4: Figure 10 As shown, the base is rotated to make the boom section rotate to a horizontal state, and a temporary fixed bracket is installed to support the concrete placing boom.

[0035] Step 5: Figure 11 As shown, the connection between the climbing rail and the mounting structure is removed. The concrete placing boom is now secured by a temporary mounting bracket. Reversing the drive motor allows the climbing rail to be raised one level. The climbing rail is then fixed to the mounting structure, and the temporary mounting bracket is disconnected from the concrete placing boom. Because the climbing rail can rise upward, the connection hole on the swivel joint can accommodate the telescopic plug-in pump pipe. This eliminates the need for top extension or bottom removal of the climbing rail. Simply provide a single connection hole on the climbing rail to accommodate the telescopic plug-in pump pipe.

[0036] Step 6: Figure 12 As shown, a pump pipe is installed to connect the pump pipe, the climbing rail column and the concrete placing boom to form a concrete transportation channel.

[0037] Step 7: Repeat steps 2 to 6 until the concrete pouring of the top layer is completed, and then remove the climbing distribution system.

[0038] In one specific embodiment, the climbing column comprises a rotating joint, a connecting hole is arranged on the rotating joint, and one end of the distributing pipe of the distributing machine is fixed with the connecting hole 16 of the rotating joint through the telescopic plug-in pump pipe 80. The telescopic plug-in pump pipe 80 comprises a first pump pipe joint 81, a second pump pipe joint 82, a first joint 83 and a second joint 84, and the first joint is detachably connected with the connecting hole. Before the distributing machine distributes, the first joint needs to be plugged and fixed with the connecting hole, before the distributing machine climbs upward with the climbing base, the first joint needs to be separated from the connecting hole, and the first pump pipe joint is inserted into the second pump pipe joint, and the telescopic plug-in pump pipe 80 is in a contracted state.

[0039] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.

[0040] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that for those skilled in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
