Description

A movable tall formwork frame

Technical Field

The utility model relates to the field of building construction equipment, in particular to a movable tall formwork frame.

Background technique

A building formwork frame is a device used to support, fix and protect building structures during construction. Its functions include supporting temporary structures, reinforcing temporary structures during construction, sharing and transferring loads, maintaining work safety, etc. The wheelbase of the frame structure is evenly arranged, the beam and slab structure is basically consistent, and it is operable. However, when the project schedule is tight and the task is heavy, it is necessary to insert multiple formwork frames into the construction at the same time, and all of them are super-high formworks. A large amount of turnover materials are invested at one time, and the subsequent workload of demolding is large, resulting in slow site cleaning and handover, affecting the progress of construction process interspersed. For this reason, technical personnel in this field have proposed a movable tall formwork frame to solve the above problems.

An embodiment provided by the utility model is a movable tall formwork frame, referring to FIGS. 1-5 , which mainly comprises a base, a full frame and load-bearing wheels 7 .

The base includes an upper bottom beam 4 and a lower bottom beam 1. The lower bottom beam 1 and multiple upper bottom beams 4 are stacked and fixed to each other. The single upper bottom beam 4 and the lower bottom beam 1 in this embodiment are I-beam components. The length of the I-beam is 6 meters. The seven lower beams are used to support the vertical poles 6, and the four upper beams are used to lift the load-bearing wheels 7. A space for installing a lifter is formed between the upper bottom beam 4 and the ground.

The full-frame includes uprights 6, which can be disc-type uprights for easy connection. The distance between uprights 6 is 900mm or 1200mm. Two or more uprights 6 are evenly distributed and fixed on the lower bottom beam 1. Scaffolding boards 8 are provided two meters below the tops of the two or more uprights 6. Adjustable top supports 15 for supporting formwork 16 are provided on the tops of the uprights 6. The adjustable top supports 15 are provided with a certain downward height range. The load-bearing wheels 7 are detachably mounted on the bottom of the upper bottom beam 4.

By setting up the upper and lower bottom beam bases, the base body structure is stable, the base is in contact with the ground surface during the formwork construction, and the contact area is large, ensuring construction safety and construction accuracy; the full-floor frame adopts an adjustable top support 15, and after removing the formwork and related connecting rods, the jacking space is obtained by adjusting the downward height range, and then the jacking device can be used to jack up the frame and the base as a whole. By installing the load-bearing wheels 7, the frame can realize mobile turnover, and the removed materials can be stacked on the scaffolding board 8 for turnover together. Compared with the process of using the jacking device and the load-bearing wheels for load-bearing construction in the prior art, the safety of personnel and equipment and the construction accuracy are greatly guaranteed, and compared with the prior art, only one-quarter of the materials need to be invested, which greatly reduces the one-time input of turnover materials, improves the turnover rate, and reduces costs. It can reduce the workload of erecting and dismantling the frame, reduce the material turnover time, improve the efficiency of demoulding, greatly improve the efficiency of site handover, facilitate subsequent interlaced construction, and speed up the construction progress. In summary, the purpose of this embodiment is achieved.

Specifically, as shown in Figure 2, horizontal rods 11 are evenly distributed and fixed between two adjacent vertical rods 6 along their height direction, and the upper and lower adjacent horizontal rods 11 are connected by diagonal braces 5. Specifically, the outer periphery of the frame is fully equipped with diagonal braces 5, and one is pulled in the middle, and the upper and lower adjacent diagonal braces 5 are arranged in a V shape; horizontal scissors braces 17 are also provided between the vertical rods 6, as shown in Figure 3, and two horizontal scissors braces 17 are specifically provided in this embodiment, one at the sweeping rod, and one at an interval of 4.5 meters; a steel wire rope 2 is provided on the outside of the full-height frame, and the two ends of the steel wire rope 2 are respectively obliquely tied to the connection nodes of the scaffolding board 8 and the vertical rod 6 and the lower bottom beam 1, and the tying diagram is shown in Figure 4. A protective fence 9 is fixedly connected to the outer upper side of the vertical rod 6 located outside the scaffolding board 8; as shown in Figure 1, a connecting steel pipe 3 for connecting to a fixed frame and/or a mobile frame outside the full-height frame is also provided on the vertical rod 6. After more than two full-height frames are installed and connected with the mobile frame/fixed frame, they are used together to form an integral support frame for the factory roof beam template, as shown in Figure 3.

The workflow of this embodiment is:

First, according to the layout diagram, the upper and lower layers of I-beams are positioned vertically and staggered, and welded into a base. The intersection is fully welded on both sides, and the connection between the upper bottom beam 4 and the lower bottom beam 1 is welded and strengthened with stiffening plates at the intersection of the four corners. Then, the center position of the vertical pole 6 of the outer circle of the frame is marked on the top of the lower bottom beam 1. At the marked position, a steel bar head with a diameter of more than 20 cm and a height of not less than 10 cm is welded to fix the position of the outer row of vertical poles 6 to prevent the frame from slipping. The adjacent vertical poles 6 are connected by snaps through the horizontal rod 11, and The upper and lower adjacent horizontal rods 11 are connected by diagonal rods 5 to finally form a full-frame frame. After the single frame is erected, it is connected to the surrounding frames to ensure that the frame in each water flow area forms an overall stable force-bearing body, and a scaffolding board 8 is fully installed 2 meters below the top of the frame, and a protective fence 9 is set outside the scaffolding board 8. After the frame is erected, it is reinforced with steel wire ropes 2 on four sides. The steel wire ropes 2 are tied at the four corner nodes of the scaffolding board 8 and the four corner nodes of the lower bottom beam 1, and are arranged according to the upper left and lower right. The upper right and lower left are connected in a pulling form, and the wire rope must be tied and tightened. Two wires are set on each surface of the frame, and a total of 8 wires are set, which are combined with the frame into a whole. The top of the vertical pole 6 is installed with a horizontal template through an adjustable top support 15, and the vertical templates are fixed by tension screws. The steel bar arrangement and concrete pouring construction are handed over later. When the work is completed and the frame needs to be moved, the wooden formwork is first disassembled, and the materials behind the wooden formwork are stacked on the scaffolding board 8 to facilitate the subsequent overall movement. Then, the adjustable top support 15 is adjusted to lower the full-hall frame as a whole. , remove the connecting steel pipe 3, and then use four jacks to lift the upper bottom beam 4 upwards, so that the entire frame moves to a certain height. At this time, the staff will insert the mounting bolts 14 into the corresponding mounting holes 10 respectively, and then pass the mounting holes reserved on the outside of the mounting plate 12 through the bottom ends of the mounting holes 10. At this time, screw the mounting nuts 13 into the mounting bolts 14 to fix the mounting plate 12 on the upper bottom beam 4. At this time, loosen and remove the jacks, so that the frame temporarily falls on the load-bearing wheels 7, and then the overall frame of the full-frame is moved to ensure stability during use.

Although the present invention has been described in detail above with specific implementation methods, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention are within the scope of protection claimed by the present invention.
