Problems solved by technology

[0005] When adopting the "pipe backing method" for the existing floor concrete pouring, the concrete pouring can only be carried out along a straight line, and the concrete is piled up at the outlet of the pump pipe, which requires manual paving from the outlet of the pump pipe to the surroundings, which has construction efficiency Low labor intensity and many other problems, the invention provides a crawler-type concrete distribution system in the floor, which can realize the full coverage of concrete in the floor, greatly reduces the labor intensity of workers, improves the construction efficiency of concrete pouring, shortens the The construction period reduces the construction cost

Embodiment 1

[0039] see figure 1 , the crawler-type in-floor concrete distribution system provided in this embodiment includes a crawler travel mechanism 100 , a rotary distribution mechanism 200 and a pump pipe follower mechanism 300 .

[0040] refer to figure 1 and figure 2 As shown, the crawler running mechanism 100 includes a platform frame 110 , a crawler roller 120 and a driving device 130 located below the platform frame 110 . As an example, the crawler roller 120 includes a driving wheel, a load wheel, a supporting wheel, a guide wheel and a covered crawler. The driving wheel is connected to a driving device 130, and the driving device 130 includes a motor, a transmission mechanism and a control system for the motor. The platform frame body 110 can be welded by square steel pipes and angle steels, and is used to support the rotary distribution mechanism 200 . The platform frame body 110 of the crawler walking mechanism 100 is provided with a connection frame fixedly connected w...

Embodiment 2

[0054] The present invention also provides a construction method for the concrete distribution system in a crawler-type floor, combined below Figure 1 to Figure 7 As shown, the construction method is further described. This construction method comprises the steps:

[0055] S1. If Figure 8 As shown, according to the size of the core tube and the area of ​​the floor slab, determine the number of fixed pump pipes 301, the outlet position and the length of the pump pipe follower 300, and then install the crawler belt travel mechanism 100, the rotary material distribution mechanism 200 and the pump pipe follower 300 , forming the crawler-type floor concrete distribution system in Embodiment 1.

[0056] S2. The rotary material distribution mechanism 200 rotates the material distribution, and walks backward through the crawler belt traveling mechanism 100, so that the rotary material distribution mechanism 200 realizes continuous and full coverage of the fixed pump tube 301 there...

Abstract

The invention relates to a crawler-type floor internal concrete distributing system and a construction method thereof, and belongs to the technical field of building construction. The concrete distributing system comprises a crawler walking mechanism, a revolving distributing mechanism and a pump tube following mechanism. The crawler walking mechanism can be supported on a steel bar net in a floor. The pump tube following mechanism comprises a plurality of rotatable pump tubes which are sequentially connected through pump tube rotating connecting pieces. The rotatable pump tubes are supportedon the steel bar net through rolling supporting seats. The revolving distributing mechanism comprises a distributing tube, a supporting frame and a revolving base. According to the concrete distributing system, the pump tube following mechanism and the revolving distributing mechanism can be driven through the crawler walking mechanism to rotate flexibly, and the revolving distributing mechanism can freely rotate and distribute materials, so that full coverage and continuous distributing of concrete in the floor are achieved; and compared with a traditional 'tube pulling method' point-type material distributing, the workload of concrete manually-paving can be significantly reduced, so that the construction efficiency is improved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a crawler-type concrete distribution system in a floor and a construction method thereof, belonging to the technical field of building construction. Background technique [0002] In the current super high-rise buildings, reinforced concrete core tube plus peripheral steel structure or peripheral hybrid structure has become the basic form of super high-rise buildings. The usual construction sequence is: first construct the core tube, then hoist the peripheral steel structure of the core tube and simultaneously lay the profiled steel composite floor slab on the floor level, and then pour the floor concrete. [0003] Usually the hoisting of the peripheral steel structure often lags behind the construction of the core tube by 8-10 floors, and the concrete pouring construction of the floor of the peripheral steel structure lags behind the hoisting of the peripheral steel structure by 4-6 floors. The material distribution device for...
