Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary facilities for cast-in-place reinforced concrete structure construction, in particular to a cantilevered disc buckle scaffolding construction system. Background Art

[0002] With the continuous development and iteration of the construction industry, various peculiar architectural shapes, complex structural forms, and different spatial combinations have gradually become the norm in modern buildings. However, this also brings great challenges to engineering construction. When the structural form of the project changes greatly and the building structure has floor misalignment (the length of the structure is greater than 3 meters), it will cause difficulties for the installation and construction of conventional scaffolding. In addition, when installing the scaffolding, the scaffolding riser is usually inserted into the adjustable support. In order to facilitate the construction operation, the diameter of the support rod of the adjustable support is smaller than the inner diameter of the scaffolding riser (usually the greater the difference between the two, the easier it is to install the scaffolding riser during construction). For projects with a small overall height of the scaffolding, the scaffolding shaking caused by the gap between the scaffolding riser and the support rod will not cause construction safety problems. However, for higher scaffolding or scaffolding erected in the air, there are higher requirements for the stability and safety of the scaffolding. Utility Model Content

DETAILED DESCRIPTION

[0023] Hereinafter, an embodiment of the cantilevered disc-lock scaffolding construction system of the present invention will be described with reference to the accompanying drawings.

[0024] The embodiments described herein are specific embodiments of the present invention, which are used to illustrate the concept of the present invention, are explanatory and exemplary, and should not be interpreted as limiting the embodiments of the present invention and the scope of the present invention. In addition to the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the claims and the contents disclosed in the specification of this application, including technical solutions that adopt any obvious replacement and modification of the embodiments described herein.

[0025] The drawings of this specification are schematic diagrams, which assist in explaining the concept of the utility model and schematically show the shapes of various parts and their mutual relationships. Please note that in order to clearly show the structure of various components of the embodiments of the utility model, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0026] Figure 1A building structure layer 1 is shown, which includes a first structure layer 11, a second structure layer 12 and a third structure layer 13 from top to bottom. On the first structure layer, the building structure has floor misalignment (the length of the structure is greater than 3 meters), and a construction joint 111 is provided on the first structure layer, which makes it difficult to install and construct a conventional scaffold on the second structure layer. In addition, when installing the scaffold, the scaffold riser is usually inserted into the adjustable support. For the convenience of construction operation, the diameter of the support rod of the adjustable support is smaller than the inner diameter of the scaffold riser (usually the greater the difference between the two, the easier it is to install the scaffold riser during construction). For projects with a small overall height of the scaffold, the scaffold shaking caused by the gap between the scaffold riser and the support rod will not cause construction safety problems. However, for higher scaffolds or scaffolds erected in the air, there are higher requirements for the stability and safety of the scaffold.

[0028] A horizontal beam 2, a ground anchor fixing device 5 and a buckle scaffold 6; the ground anchor fixing device 5 fixes the horizontal beam 2 on the building structure layer 1; the buckle scaffold 6 includes an adjustable drag seat 61 and a scaffold body 62;

[0029] The adjustable drag seat 61 includes a base 611, a support rod 613 and an adjustment tray 612. The lower end of the support rod 613 is fixedly connected to the base 611. The adjustment tray 612 is installed on the support rod 613. The height position of the adjustment tray on the support rod 613 is adjusted by rotating the adjustment tray 612. In a preferred embodiment, the support rod is provided with an external thread, and the adjustment tray 612 is provided with a thread structure adapted to the external thread. The support rod is a cylindrical structure, and its diameter is smaller than the inner diameter of the steel pipe upright of the buckle scaffolding; the base 611 is fixedly connected to the horizontal beam 2.

[0031] When the cantilevered disc-lock scaffolding construction system of the above embodiment of the utility model is used, when it is necessary to carry out construction at the location of the first structural layer, the horizontal beam 2 can be first fixed on the second structural layer using the anchor fixing device 5, and the disc-lock scaffolding can be installed using the horizontal beam to carry out construction on the first structural layer. At the same time, since the adjustable drag seat is provided with a top block and an adjusting rod, the steel pipe upright of the scaffolding body is sleeved on the top of the supporting rod when the top block is retracted into the accommodating cavity, and then the top block is extended out of the accommodating cavity by rotating the adjusting rod and is used to press against the inner wall of the steel pipe upright, thereby eliminating the gap between the steel pipe upright and the supporting rod, avoiding shaking between the two, and improving the stability and construction safety of the disc-lock scaffolding.

With the above-mentioned adaptation arrangement, when the adjusting rod is rotated in the same direction, the first top block and the second top block can be extended or retracted from the corresponding accommodating cavity at the same time, thereby achieving a tightening effect. A tool hole (such as a tool hole with a square structure) is provided at the end of the adjusting rod, and a tool can be inserted into the tool hole from the hole surrounded by the internal thread of the top block, thereby rotating the adjusting rod.

In order to prevent the setting of the anchor body from causing damage to the corresponding position of the second structural layer, a metal plate 56 is provided at the position where the anchor body is provided in the second structural layer, and the metal plate is used for protection. Through the setting of the ground anchor fixing device of the above embodiment, the horizontal beam can be firmly fixed on the second structural layer, so that the buckle scaffolding can be installed on the horizontal beam for construction. Combined with Figure 2 As shown, the anchor body is roughly a "J"-shaped structure, and the anchor body and the truss steel bars can be connected by welding. The horizontal beam can be clamped in the anchor body by the first and second wooden beams, and the setting of the wedge block can prevent the horizontal beam from shaking left and right. In a further preferred embodiment of the cantilevered disc buckle scaffolding construction system, the ground anchor fixing device 5 also includes a first limiting steel bar 52, and the first limiting steel bar 52 is fixedly connected to the horizontal beam 2 and the anchor body respectively. By setting the first limiting bar, the horizontal beam can be prevented from moving in the straight line direction where the horizontal beam is located, thereby improving the stability of the disc buckle scaffolding setting.

Specifically, an embedded plate 41 is arranged on the upper surface of the third structural layer 13, and the second end 43 of the support rod 4 is connected to the embedded plate 41.

[0036] In a preferred embodiment of the cantilevered disc-locked scaffolding construction system, as Figure 1 and Figure 3 As shown, it also includes a steel wire rope 3, one end of which is connected to the lower surface of the first structural layer 11, and the other end of the steel wire rope 3 is connected to the horizontal beam 2. A lifting ring 32 is set on the lower surface of the first structural layer 11, and the end of the steel wire rope passes through the lifting ring and is fixed by a buckle 31. A second limiting steel bar 33 is welded on the inner side of the horizontal beam 2 to fix the steel wire rope, which is used to clamp the steel wire rope to prevent it from moving further toward the second structural layer. Figure 3 Also shown is a connecting beam 7, which is vertically welded to the horizontal beam and is used to connect two or more mutually parallel horizontal beams into a whole, thereby further improving the stability of the horizontal beam and the stability of the coiled scaffolding.
