Embodiment 1

[0047] The following will combine Figure 1 to Figure 4 , the present invention provides an integral steel platform 10 formwork super large bearing capacity wall attachment system for further introduction.

[0048] For illustrative purposes, figure 1 Only one grid of the core tube is shown in the figure. The steel platform 10 is set on the platform formwork 11. The platform formwork 11 is located in the grid of the core tube 30. The support steel beam 12 and the climbing steel beam are passed under the platform formwork 11. 13 is fixed on the core tube 30. The two ends of the supporting steel beam 12 and the climbing steel beam 13 are provided with telescopic corbels, which are called supporting corbels and climbing corbels respectively. For the detailed structure of the steel platform and platform formwork, this The invention does not need to be introduced too much. The wall attachment system of the present invention is arranged on the wall body of the core tube 30, and is ...

Embodiment 2

[0060] Since the shear key 26 is embedded in the core tube, the difficulty of demolding is increased to a certain extent. In order to reduce the difficulty of demolding, further, such as image 3 and Figure 5 As shown, the cross-section of the shear key 26 is a right-angled trapezoid, the right-angled side of the right-angled trapezoid is arranged horizontally, the hypotenuse is located above the right-angled side, the two bottom sides are vertically arranged and the longer right-angled side is welded and fixed to the horizontal purlin . More preferably, an arc-shaped chamfer is formed between the hypotenuse of the right-angled trapezoid and the shorter right-angled side.

[0061] Because the shear key 26 is embedded in the core tube, the difficulty of formwork removal increases. If the formwork is violently removed, the wall of the core tube 30 and the attached wall unit 20 may be damaged, affecting the concrete quality of the core tube and reducing the turnover times of th...

Embodiment 3

[0067] The invention provides a construction method of the super large bearing capacity attached wall system of the integral steel platform formwork, the following is combined with the attached figure 1 to attach Figure 7 for further clarification. The construction method includes:

[0068] S1: Pre-embed the fixing piece 28 on the wall of the core tube 30, and set reserved holes. The fixing piece 28 and the reserved hole match the bolt hole 25 and the shear key 26 of the wall-attached unit 20 respectively. Wherein, the fixing part 28 may be a pre-embedded screw, and the wall-entry end of the pre-embedded screw is hook-shaped or claw-shaped or has an enlarged end to increase the bearing capacity of the fixing frame. The position and size of the reserved holes match the shear key 26, and the position and size of the fixing piece 28 match the position and size of the shear key 26.

[0069] S2: Insert the shear keys 26 of multiple wall-attached units 20 respectively into the r...

Abstract

Disclosed are a super-large load bearing capacity wall-attached system for integrated scaffolding and formwork equipment with a steel platform, and a construction method therefor. The wall-attached system comprises several wall-attached units (20), wherein the wall-attached unit (20) comprises a wall-attached steel plate (21); a shear key (26) and a bracket placement device (27) are respectively arranged on two sides of the wall-attached steel plate (21); the bracket placement device (27) supports scaffolding and formwork equipment (11) with a platform, and the shear key (26) is attached to a wall body of a core tube (30); adjacent wall-attached units (20) are assembled and fixed to form an integrated bearing mechanism; and the wall-attached units (20) are provided with a demolding device. The construction method for the super-large load bearing capacity wall-attached system for integrated scaffolding and formwork equipment with a steel platform comprises: T1, after the binding of steel bars for a first layer of wall body of the core tube (30) is completed, mounting the wall-attached units (20), anchoring steel plates (40) and normal formworks (50) and assembling same to constitute a formwork system; T2, pouring concrete, and removing the normal formworks (50) in a timely manner; T3, mounting a steel platform system; T4, repeating steps T1 and T2 to complete the construction of a second layer of wall body of the core tube (30); T5, using a hydraulic climbing system of the scaffolding and formwork equipment (11) with the platform to enable the steel platform (10) to climb by one floor; T6, removing formworks for the first layer of wall body of the core tube (30), and mounting the formworks to a third layer of wall body of the core tube; and T7, repeating steps T4-T6 to complete the construction of all wall bodies of the core tube (30). By means of the super-large load bearing capacity wall-attached system for integrated scaffolding and formwork equipment with a steel platform, and the construction method therefor, an acting force from the scaffolding and formwork equipment (11) with the platform can be dispersed to the shear keys (26) of the multiple wall-attached units (20), thereby improving the load bearing capacity and safety of the scaffolding and formwork equipment (11) with the platform.

Description

technical field [0001] The invention relates to a wall-attached system with super large bearing capacity of an integral steel platform formwork and a construction method, belonging to the technical field of building construction. Background technique [0002] Integral steel platform formwork is the main equipment for the construction of high-rise and super high-rise core tube shear wall concrete structures. For example, a formwork system of a cylinder support type power built-in integral jacking steel platform disclosed in Chinese patent CN102661039B, the support of the cylinder support can be The telescopic corbel is supported in the reserved hole of the concrete shear wall to realize the shelving and climbing needs of the formwork equipment. In order to avoid the vertical reinforcement of the shear wall structure and reduce damage to the structure, the width of the reserved opening is generally controlled within 150mm, resulting in a small supporting area of ​​the telescop...
