Description

Technical Field

[0001] The utility model belongs to the field of super high-rise building construction, relates to an inner climbing formwork supporting device for a core tube connecting beam, and is a method for processing a climbing formwork pre-embedded in a core tube on a beam. Background Art

[0002] With the gradual increase in super high-rise buildings, climbing formwork has also become the main formwork system for building super high-rise buildings. During the construction process, the shear wall of the inner tube will also be transformed into a beam as the height changes. The embedded parts of the previous climbing formwork position will lose their attachment due to insufficient beam height. At this time, a transferable and lightweight device is needed to provide an attachment point; the traditional approach is to make concrete columns, which has the disadvantage of wasting materials and incurring secondary cutting costs; and if steel columns are selected as support points, the height of the steel columns must be set to the same as the floor height, and as the floor height changes, the steel columns also need to be made into different heights. Under complex construction conditions on site, the specifications of the steel columns are also variable; in addition, during the construction process, the distance between the climbing formwork platform and the wall is relatively close, which seriously affects the turnover of the steel columns, and there are also safety hazards in the turnover.

[0003] In order to solve the problem of embedded parts of climbing formwork meeting beams in the core tube of super high-rise buildings, it is necessary to upgrade and simplify the traditional approach; it is necessary to design a simple, unique and lightweight support device, which can be achieved by transforming the position of the force point.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] Figure 1 It is a structural schematic diagram of the utility model. Figure 2 It is a side view of the utility model. Figure 3 It is a top view of the utility model, referring to Figure 1-3 As shown, the utility model is a climbing formwork support device for the core tube connecting beam, comprising a bearing plate 1, which is welded together with a rib plate 2, an additional plate 6, and a diaphragm 7 to form a main force-bearing system; a hoisting part 3 is arranged on the upper part of the bearing plate 1 to facilitate the turnover of the support system and reduce manual handling. Four embedded connection holes 4 are arranged on the upper part of the bearing plate 1; four embedded parts 8 are fixed to the embedded connection holes 4 by high-strength bolts 10. Two hanging seat connection holes 5 are arranged on the lower part of the bearing plate 1; the hanging seat 9 is fixed to the hanging seat connection holes 5 by high-strength bolts 10, and a connecting nut 11 is sleeved on the other end of the high-strength bolt 10. The diaphragm 7 is welded to the inner side of the bearing plate 1, does not contact the concrete surface, and does not affect the embedding of the embedded parts 8; the additional plate 6 is connected to the outer side of the bearing plate 1, which provides integrity for the device without affecting the connection of the hanging seat 9 pre-installation.

[0023] Specifically, a climbing formwork support device for the core tube connecting beam includes a load-bearing plate 1, a rib plate 2, a hanging part 3, an embedded connection hole 4, a mounting connection hole 5, an additional plate 6, a transverse partition 7, an embedded part 8, a mounting 9, a high-strength bolt 10, and a connecting nut 11; the embedded part 8 is embedded in the beam inside the core tube; usually, four embedded parts 8 are embedded in one position on site, and the four embedded parts 8 fix the entire support device on the beam to bear the load transmitted by the climbing formwork; the embedded connection holes 4 are arranged on the load-bearing plate 1, and their lateral spacing is equal to the embedded part spacing of the climbing formwork, and the vertical spacing must ensure that the lower embedded connection holes 4 can also be embedded in the beam.

[0024] The bracket connection hole 5 is arranged at the lower part of the bearing plate 1, and its height should be the same as the height of the embedded parts of other climbing formwork positions to ensure that all climbing formworks are at the same horizontal position. At the same time, it is necessary to ensure that the bracket connection hole 5 is at the lower part of the beam and does not affect the installation of the bracket. It is also necessary to reserve operating space for installing nuts to ensure that the entire bracket is on the bearing plate 1.

[0025] The hoisting member 3 is welded to the upper side of the bearing plate 1 , and a hoisting hole is provided on the hoisting member 3 , and the hoisting hole as a whole exceeds the bearing plate 1 , so as to facilitate the hoisting and turnover of the supporting device on site by means of a hoist or other machines.

[0026] The ribs 2 are welded on both sides of the load-bearing plate 1 and are mainly used to bear the bending moment generated by the bracket on the supporting device. Two ribs 2 are provided, and the distance between them is sufficient to leave a distance for other components to meet the installation requirements of the high-strength bolts 10 and the bracket 9.

[0027] The transverse partition 7 is welded to the outer side of the bearing plate 1 and does not contact the concrete surface. It mainly resists the torque generated by the bracket 9 on the supporting device to ensure that the supporting device as a whole does not deform.

[0028] The additional plate 6 is welded to the inner side of the load-bearing plate 1 and is located below the beam. It is mainly used to resist the torque generated by the connection between the hanger 9 and the high-strength bolts 10 on the supporting device to ensure that the supporting device as a whole does not deform.

[0029] Specific working steps:

[0030] First, open a lifting hole with a diameter of 32 on the lifting part 3, open four embedded connection holes 4 on the upper part of the load-bearing plate 1, and open two bracket connection holes 5 on the lower part. The sizes of the embedded connection holes 4 and the bracket connection holes 5 are consistent with the holes on the climbing formwork bracket plate. Then weld the ribs 2, lifting parts 3, additional plates 6, and diaphragms 7 to the load-bearing plate 1 to form an integrated force system. Embed the embedded parts 8 in the beam during concrete pouring. After the concrete strength is reached, use the force bolts to fix the embedded parts 8 to the load-bearing plate 1 through the embedded connection holes 4. Use high-strength bolts 10 and connecting nuts 11 to fix the bracket 9 to the load-bearing plate 1 through the bracket connection holes 5. The climbing formwork is connected to the bracket 9 to transfer the force to the support device, and the support device then transfers the force to the beam of the core tube.

[0031] The supporting device is installed in a sealed shaft and large lifting equipment cannot be used. The overall design width is less than 150 mm (the distance between the climbing formwork platform and the core tube wall), which optimizes the weight of each rod and facilitates installation and turnover by construction personnel.

[0032] The hanging seat 9 is connected to the hanging seat connecting hole 5 on the bearing plate 1, so that the force of the climbing formwork is fully transmitted to the bearing plate 1, and the climbing formwork does not need to consider the absence of an attachment position point.

[0033] During construction, the complex conditions of the construction space and working conditions on site are comprehensively considered. In addition to meeting the requirements of the climbing formwork meeting the beam, the convenience of on-site construction and the simplicity of operation for workers must also be considered. This is to completely solve the impact of the embedded parts of the climbing formwork meeting the beam on the ongoing construction work.

[0034] It should be noted that the protection scope of the present invention is not limited to the above embodiments, and all technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
