[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. Cantilever scaffolding is a cantilever bracket composed of horizontal bars or diagonal bars cantilevered from the building, suspended above the bottom surface. As a common aerial work equipment, it has many types and is widely used in construction. Due to the structural design and load-bearing needs, traditional cantilever scaffolding has some defects: traditional cantilever scaffolding requires pre-embedded support parts, that is, embedded parts need to be installed in advance, and after installation, it is necessary to wait for the concrete to solidify and form. After the operation is completed, the embedded parts need to be removed to make room for subsequent projects, resulting in an increase in construction period and cost. In addition, traditional cantilever scaffolding has the problems of complex construction, low safety performance, and poor suspension stability.

[0036] Based on the above defects, the present application provides an embodiment, which is the best solution for a pre-buried assembled cantilever scaffold. Specifically, the present embodiment takes a three-story floor as an example to illustrate the structure of the cantilever scaffold.

[0037] Specifically, Figure 1 , is the structural diagram of the cantilever scaffolding in side view, Figure 1 It is shown in the figure that the cantilever scaffolding includes a first support plate 1 and a second support plate 2. The first support plate 1 is placed on the second floor slab 8b, and the second floor slab 8b supports the first support plate 1. The second support plate 2 is placed on the first floor slab 8a, and the first floor slab 8a supports the second support plate 2, so that the second support plate 2 is located at the lower end of the first support plate 1. At the same time, the second support plate 2 extends to the outer edge side of the first floor slab 8a, and the extended part serves as a platform for building a construction scaffolding 4, that is, the first support plate 1 and the second support plate 2 serve as the frame structure of the cantilever scaffolding.

[0038] Furthermore, in the present embodiment, the first support plate 1 and the second support plate 2 are both composed of a plurality of I-beams arranged in parallel, the arrangement direction of the I-beams points to the wall panels on both sides of the floor slab, and each I-beam of the second support plate 2 extends out of the outer edge side of the first floor slab 8a, and the I-beams of the first support plate 1 and the I-beams of the second support plate 2 extend in the same direction.

[0039] Furthermore, in order to avoid fixing the first support plate 1 and the second support plate 2 by setting embedded parts, as shown in FIG. Figure 1 , indicating that the cantilever scaffolding also includes longitudinal support members 3a, 3b, the longitudinal support member 3a is supported between the lower side of the third floor slab 8c and the first support plate 1, and the longitudinal support member 3b is supported between the lower side of the second floor slab 8b and the second support plate 2, so that the longitudinal support members 3a, 3b respectively fix the first support plate 1 and the second support plate 2 to avoid displacement of the first support plate 1 and the second support plate 2 in the stacking direction of the floor slabs.

[0040] Furthermore, in the present embodiment, each I-beam of the first support plate 1 is correspondingly provided with two longitudinal support members 3 a , and each I-beam of the second support plate 2 is correspondingly provided with two longitudinal support members 3 b .

[0041] Further, such as Figure 1 The longitudinal support members 3a and 3b are specifically rods, wherein in order to increase the stability of the longitudinal support members 3a and 3b, support seats 31a are arranged at both ends of the longitudinal support member 3a, the support seat 31a at one end of the longitudinal support member 3a is welded to the I-beam of the first support plate 1, and the support seat 31a at the other end abuts against the lower side of the third floor slab 8c; at the same time, support seats 31b are arranged at both ends of the longitudinal support member 3b, the support seat 31b at one end of the longitudinal support member 3b is welded to the I-beam of the second support plate 2, and the support seat 31a at the other end abuts against the lower side of the second floor slab 8b.

[0042] Furthermore, the cantilever scaffolding also includes transverse support members 7a and 7b, which are also rods and are supported between two I-beams. Specifically, the transverse support member 7a is supported between two I-beams of the first support plate 1, and the transverse support member 7b is supported between two I-beams of the second support plate 2.

[0043] Further, such as Figure 1 After the frame structure of the cantilever scaffolding is completed, a construction scaffolding 4 needs to be built on the frame. In the present embodiment, the construction scaffolding 4 is placed on the outer edge of the three-story slab and extends along the stacking direction of the three-story slab. The lower end of the construction scaffolding 4 is supported on the second support plate 2 and extends out of the outer edge of the first floor slab 8a.

[0044] Further, such as Figure 1 In this embodiment, the construction scaffolding 4 includes two grid structures 41, which are vertically arranged between the floor slabs. The two grid structures 41 are distributed along the extension direction of the second support plate 2 and are supported by the part of the second support plate 2 extending out of the outer edge of the floor slab.

[0045] Further, such as Figure 2 , is a structural schematic diagram of the cantilever scaffolding in the front view, showing that each grid structure 41 is composed of a plurality of cross bars 412 and a plurality of vertical bars 413, the plurality of vertical bars 413 are arranged parallel to the longitudinal supports 3a, 3b, the cross bars 412 and the vertical bars 413 are arranged vertically, the plurality of cross bars 412 are evenly spaced along the stacking direction of the floors, the plurality of vertical bars 413 are evenly spaced along the extending direction of the cross bars 412, and the cross bars 412 and the vertical bars 413 are connected by fasteners 44.

[0046] Further, such as Figure 1 The cantilever scaffolding also includes anchor members 5a and 5b. The anchor member 5a connects the construction scaffolding 4 with the first support plate 1, and the anchor member 5b connects the construction scaffolding 4 with the second support plate 2, thereby providing a pulling force pointing to the floor direction to the construction scaffolding 4, so that the construction scaffolding 4 is firmly connected with the first support plate 1 and the second support plate 2. At the same time, the anchor members 5a and 5b both play the role of transverse cross bars in traditional scaffolding, and the anchor member 5b also plays the role of transverse sweeping rod in traditional scaffolding.

[0047] Further, such as Figure 1 The anchor member 5a extends to pass through the upper part of the two grid structures 41 in sequence, and the nodes 411 corresponding to the two grid structures 41 are also connected by fasteners 44. The anchor member 5b extends to pass through the lower part of the two grid structures 41 in sequence, and the nodes 411 corresponding to the two grid structures 41 are also connected by fasteners 44.

[0048] Further, such as Figure 1 The construction scaffolding 4 also includes a connecting rod 42, and the connecting rod 42 is used to connect the corresponding nodes 411 in the middle of the two grid structures 41 through fasteners 44; at the same time, in the present embodiment, the construction scaffolding 4 also includes pull ropes 43a and 43b, and the pull ropes 43a and 43b are made of steel wire ropes, one end of the pull rope 43a is connected to one end of the connecting rod 42, one end of the pull rope 43b is connected to the other end of the connecting rod 42, and the other ends of the pull ropes 43a and 43b are connected to the end of the first support plate 1; in this way, the gravity exerted on the construction scaffolding 4 can be decomposed multiple times and transferred to the first support plate 1, thereby reducing the pressure of the construction scaffolding 4 on the second support plate 2, and avoiding the second support plate 2 from being damaged due to excessive load.

[0049] Specifically, both ends of the connecting rod 42 are provided with pin holes, a gusset plate is welded on the first support plate 1 near the outer edge of the second floor slab 8b, and holes are formed on the gusset plate. The two ends of the pull ropes 43a and 43b are respectively tied and connected to the holes of the gusset plate and the pin holes on the connecting rod 42.

[0050] Further, such as Figure 1 The anchor members 5a and 5b are connected to the first support plate 1 and the second support plate 2 respectively in the following manner: the anchor members 5a and 5b are rod members, and a tie base 52a is welded on the I-beam of the first support plate 1, and the end of the anchor member 5a away from the construction scaffolding 4 passes through the tie base 52a, and an anchor bolt 53a is provided at the end of the anchor member 5a, which is screwed to the anchor member 5a, and the anchor bolt 53a abuts against the tie base 52a, forming a pulling and strengthening effect on the construction scaffolding 4; a tie base 52b is welded on the I-beam of the second support plate 2, and the end of the anchor member 5b away from the construction scaffolding 4 passes through the tie base 52b, and an anchor bolt 53b is provided at the end of the anchor member 5b, which is screwed to the anchor member 5b, and the anchor bolt 53b abuts against the tie base 52b, forming a pulling and strengthening effect on the construction scaffolding 4.

[0051] Further, such as Figure 1 A pull piece support seat 54a is welded on the I-beam of the first support plate 1, and the pull piece support seat 54a is located between the tie base 52a and the construction scaffolding 4. The anchor pull piece 5a also passes through the pull piece support seat 54a to support the middle part of the anchor pull piece 5a; at the same time, a pull piece support seat 54b is welded on the I-beam of the second support plate 2, and the pull piece support seat 54b is located between the tie base 52b and the construction scaffolding 4. The anchor pull piece 5b also passes through the pull piece support seat 54b to support the middle part of the anchor pull piece 5b.

[0052] Further, such as Figures 1-2 The cantilever scaffolding also includes a protective net 6, which is placed on a side of the construction scaffolding 4 away from the first support plate 1 and the second support plate 2.

[0053] Further, such as Figure 3 , for this cantilever scaffolding Figure 1 Detailed view of point A in the middle. Figure 4 For this cantilever scaffolding Figure 1 Detailed view of point B in the middle. Figure 5 For this cantilever scaffolding Figure 1 The detail diagram at point C in the middle shows that the anchor members 5a, 5b and the connecting rod 42 are extended to be connected to the protective net 6, and the anchor members 5a, 5b and the connecting rod 42 are provided with latch holes 51a, 51b, 421 on the side close to the protective net 6, and latch plates 61 are provided at positions corresponding to the protective net 6 and the latch holes 51a, 51b, 421, and the latch holes 51a, 51b, 421 are connected to the latch plates 61 by bolts and nuts.
