Description

Technical Field

[0001] This utility model belongs to the field of foundation pit engineering technology and relates to an all-steel ring beam for retaining structure. Background Technology

[0002] Conventional retaining structure materials include reinforced concrete, steel, and cement-soil, but due to limitations in shape and splicing conditions, the ring beam at the top of the retaining structure is usually made of concrete. However, concrete requires a certain age to reach its full strength before subsequent excavation and other work can proceed, thus impacting the project schedule on the critical path. Currently, for projects with tight schedules, high-strength grouting materials or high-strength concrete are often used to reduce the time required to reach design requirements. This increases costs, and the inability to recycle leads to waste and construction debris. More importantly, this method still requires a certain amount of time (usually 2-3 days) to reach the predetermined strength, causing further delays. This utility model is proposed based on these issues. Utility Model Content

[0003] The purpose of this invention is to provide an all-steel ring beam for enclosure structures, which enables rapid connection and recycling of the ring beam to the enclosure structure.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A steel ring beam for an enclosure structure, comprising:

[0006] A standard section of a ring beam is formed by splicing several precast ring beams in sequence. The precast ring beam has a precast through hole in the middle that allows the enclosure support structure to be fitted into it, so that the precast ring beam can be detachably connected to the enclosure support structure.

[0007] A cast-in-place transition section located at a corner and connecting two adjacent standard sections of ring beams.

[0008] Furthermore, the precast ring beam is a precast steel box.

[0009] Furthermore, the two ends of the precast ring beam are provided with joint structures that can be connected to each other.

[0010] Furthermore, the joint structure has pre-drilled holes, and adjacent precast ring beams are connected by connecting bolts that match the pre-drilled holes.

[0011] Furthermore, the precast ring beam contains several ribs to improve stress stability.

[0012] Furthermore, the size of the prefabricated through hole is larger than the area into which the enclosure support structure is fitted, so that there is a gap between the prefabricated through hole and the enclosure support structure, and the gap is filled with adhesive material.

[0013] Furthermore, the adhesive material is a hot-melt material.

[0014] Furthermore, the cast-in-place transition section includes an anchor plate connected to the standard section of the ring beam, and cast-in-place material for connecting the retaining support structure and the anchor plate at the corner.

[0015] Furthermore, the enclosure support structures are connected by interlocking fasteners.

[0016] Furthermore, the retaining support structure is a steel pipe pile, a precast concrete pile, or a steel section.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] (1) It can realize the rapid connection between the ring beam and the enclosure structure without waiting for a certain age, which greatly saves the construction period;

[0019] (2) The all-steel structure can be recycled, reducing construction waste, saving resources, and is green, low-carbon and environmentally friendly;

[0020] (3) Using standardized components can enable rapid installation and greatly improve efficiency. Attached Figure Description

[0038] To achieve rapid connection and recycling of the ring beam and the enclosure structure, this utility model provides an all-steel ring beam for the enclosure structure, comprising:

[0039] A standard section of the ring beam is formed by splicing several prefabricated ring beams 1 in sequence. The prefabricated ring beam 1 has a prefabricated through hole in the middle that allows the enclosure support structure to be fitted into it, so that the prefabricated ring beam 1 can be detachably connected to the enclosure support structure.

[0040] A cast-in-place transition section located at a corner and connecting two adjacent standard sections of ring beams.

[0041] By using precast ring beams 1, which are detachably connected to the maintenance support structure, to replace concrete pouring materials, the ring beam structure at the top of the maintenance structure can be constructed. This allows for a rapid connection between the ring beam and the maintenance structure. After construction is completed, the standard section of the ring beam can be disassembled and recycled from the maintenance support structure and the cast-in-place transition section.

[0042] In some specific embodiments, the precast ring beam 1 is a precast steel box or the like.

[0043] In some specific embodiments, the two ends of the precast ring beam 1 are provided with joint structures 4 that can be connected to each other.

[0044] Furthermore, the joint structure 4 is a pre-drilled hole, and preferably, adjacent precast ring beams 1 are connected by connecting bolts 5 that match the pre-drilled hole.

[0045] In some specific embodiments, the precast ring beam 1 contains several ribs 6 for improving stress stability.

[0046] In some specific embodiments, the size of the pre-fabricated through hole is larger than the area into which the enclosure support structure is fitted, resulting in a gap 3 between the pre-fabricated through hole and the enclosure support structure, which is filled with adhesive material. Furthermore, the adhesive material is a hot-melt material 11, such as commonly used hot-melt anchoring adhesive; for example, it can be polyamide hot-melt adhesive, polyurethane hot-melt adhesive, etc.

[0047] In some specific embodiments, the cast-in-place transition section includes an anchor plate 9 connected to the standard section of the ring beam, and cast-in-place material for connecting the retaining support structure at the corner and the anchor plate 9. Preferably, the cast-in-place material can be high-strength grouting material 8 (meeting the filling and reinforcement requirements in foundation pit engineering), hot-melt material 11, etc.

[0048] In some specific embodiments, the enclosure support structures can be connected by locking buckles 7.

[0049] In some specific embodiments, the retaining support structure is a retaining steel pipe pile 2, a precast concrete pile, or a steel section 10.
