Description

Technical Field

[0001] The invention belongs to the field of construction requiring rapid edge protection, and in particular relates to an edge protection device and a construction method thereof. Background Art

[0002] For edge protection of trench foundation pits that require temporary support and rapid construction turnover, the traditional method uses steel pipe brackets with snap-on connections, and sets horizontal and vertical bars to enclose the pit edges. It requires a lot of manpower to set up, and because the connection is snap-on, the overall structure is not strong, especially the rear support. Another method uses shaped guardrails. Under the premise of having a good foundation, shaped guardrails can have better protection performance, but the foundation needs to be treated when constructing guardrails. If a stable shaped guardrail needs to be established at the edge of the excavated earth pit, it is often necessary to harden the ground locally. The cycle is long and the cost is high, which is not suitable for short-cycle and high-turnover pit construction. Summary of the invention

[0046] This embodiment provides an edge protection device, Figure 1 Schematic diagram of the structure of this embodiment. Figure 1 As shown, it includes a positioning cap 1, a containment frame 2, a sleeve 3 and a spherical joint 4, wherein:

[0047] The enclosure frame 2 includes multiple transverse frames 21, multiple longitudinal frames 22, multiple oblique frames 23 and multiple surrounding frames 24. In this embodiment, the transverse frames 21, longitudinal frames 22, oblique frames 23 and surrounding frames 24 of the enclosure frame 2 all adopt steel pipe structures, more specifically, circular steel pipe structures with simple structures. By using steel pipes as the main body of the enclosure frame 2, material selection is convenient and the production cost is low. The transverse frames 21, longitudinal frames 22, oblique frames 23 and surrounding frames can be easily disassembled. Compared with the disadvantage that traditional enclosures need to be replaced as a whole when one part is damaged, this device can be manufactured in a modular manner, which saves more investment.

[0048] The positioning cap 1 includes a plurality of grooves 11. The positioning cap 1 is used to connect the enclosure frame, and a rotating shaft is set at the connection position. In this embodiment, the positioning cap is made of metal material, in the shape of a round cake, with a thickness referring to the thickness of a round tube, and grooves 11 are carved along the connection direction of the round tube and the folding direction of the round tube;

[0049] The sleeve 3 includes a plurality of sleeves, which serve as folding devices. In the actual construction process, the sleeve 3 is processed with a steel pipe that is one size larger than the round steel pipe used in the enclosure frame 2, so as to insert the steel pipe of the enclosure frame 2 and connect it to the positioning cap 1. When in use, each transverse frame 21, longitudinal frame 22 and oblique frame 23 are connected to one of the grooves 11 through a sleeve 3;

[0050] Figure 2 Schematic diagram of the structure of the edge protection device of this embodiment when it is folded up. Figure 2As shown, the spherical joint 4 is arranged at the connection between the surrounding frame 24 and the transverse frame 21, the longitudinal frame 22, and the oblique frame 23, and is used to connect the various folding parts. The structure adopts triangular oblique braces to be stable and reliable. The force point of the protective device is in the groove of the positioning cap 1 rather than the connection, so that it has good rigidity under severe impact, which greatly improves the safety compared with traditional protection methods.

[0051] As an optional embodiment, a first axial hole 12 is provided on the positioning cap 1, and a second axial hole 31 is provided on the sleeve 3. The first axial hole 12 and the second axial hole 31 are connected by a rotating shaft 5. When in use, the intercepted skeleton is connected to the positioning cap through the sleeve, and the connecting end is connected with a rotating shaft to ensure smooth folding of the skeleton.

In this embodiment, the slot 32 is set as a circular slot, and the slot 32 includes a first slot 321 and a second slot 322. In actual use, the shape of the slot 32 can be set to other shapes or styles according to actual use needs, as long as the buckle 211 cooperates with the slot 32. Buckles 211 corresponding to the slot 32 are provided on the transverse frame 21, the longitudinal frame 22 and the oblique frame 23, or hollows are carved on the side wall of the sleeve 3, and pins matching the hollows are welded on the steel pipes of the transverse frame 21, the longitudinal frame 22 and the oblique frame 23 to fix the position of the frame. Preferably, the hollow is set to an L shape.

[0053] As an optional implementation, the buckle 211 is set as a telescopic buckle, so that it is simple, convenient and efficient to use, and the disassembly is time-saving and labor-saving, and the work efficiency is high. A work shift (2 people) using this protective device can shorten the installation time by 3 to 4 times compared with the traditional enclosure. It is also easy to install, and compared with the traditional method, the construction quality is easier to guarantee, the personnel input is reduced, the labor efficiency is improved, and the construction progress is accelerated.

[0054] Specifically, Figure 4 is a schematic diagram of the structure of the buckle of this embodiment. Figure 4As shown, a cavity 212 is provided on the transverse frame 21, the longitudinal frame 22 and the oblique frame 23, and an elastic member 213 is provided in the cavity 212. In this embodiment, the elastic member 213 adopts a spring structure. In actual use, a spring sheet or other elastic object can also be used. One end of the telescopic buckle 211 is located in the cavity 212, and the other end of the telescopic buckle 211 extends out of the cavity 212. During installation, when the skeleton steel pipe is pushed into the positioning cap 1, the telescopic buckle 211 automatically pops out into the slot 32, and the telescopic buckle 211 is fixed through the first slot 321; when disassembly is required, press the telescopic buckle 211 downward and pull out the skeleton steel pipe outward, and the telescopic buckle 211 automatically pops out after sliding to the second slot 322.
