Description

Technical Field

[0001] This utility model relates to the field of concrete component connection technology, and more specifically to a steel structure connection node for concrete components. Background Technology

[0002] Precast concrete structures refer to structures in which precast concrete components are fabricated to predetermined dimensions, pre-cast into a monolithic structure in a factory or prefabrication site, and then transported to the construction site for assembly into a building structure. Precast concrete structures are widely used both domestically and internationally due to their advantages such as short construction period, fast production speed, good environmental performance, and excellent quality. They represent one of the important directions for the development of building structures in my country and are conducive to the industrialization of my country's construction industry.

[0003] However, once a precast concrete structure is cast, it cannot be disassembled and the precast concrete components cannot be disassembled for secondary assembly, which fails to meet the development principles of sustainable use and the 3R [Reduce, Reuse, Recycle] development concept.

[0004] Therefore, how to provide a concrete component connection node that is easy to disassemble and can be disassembled for secondary assembly is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a steel structure connection node for concrete components, which solves the technical problem that the concrete components in the precast concrete structure cannot be separated and cannot be disassembled for secondary assembly after pouring.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A steel structure connection node for concrete components includes a square tube, a first concrete component, a second concrete component, and a third concrete component. The openings of the square tube are arranged vertically, and its outer side wall has a first wall surface. The first concrete component is arranged above the square tube and is detachably connected to the square tube via a first connecting steel component. The second concrete component is arranged below the square tube and is detachably connected to the square tube via a second connecting steel component. The third concrete component is arranged on one side of the square tube and is detachably connected to the first wall surface via a third connecting steel component.

[0008] Through the above technical solution, this utility model discloses a steel structure connection node for concrete components. Concrete component one, concrete component two, and concrete component three are respectively arranged above, below, and to the right of the square tube, and are respectively assembled with the square tube through connecting steel component one, connecting steel component two, and connecting steel component three. Concrete component one, concrete component two, and concrete component three can all be disassembled from the square tube individually for secondary assembly.

[0009] Preferably, the connecting steel component is a connecting steel pipe. The top end of the connecting steel pipe is integrally cast and fixed to the bottom of the concrete component, and its bottom end is inserted into the cavity of the square tube. The square tube and the connecting steel pipe are provided with multiple corresponding bolt holes, and high-strength bolts are used to connect the square tube and the connecting steel pipe through the bolt holes.

[0010] The beneficial effect of adopting the above technical solution is that the high-strength bolts can stably connect the steel pipe and the square tube without detaching, thereby making the connection between the concrete component and the square tube more secure.

[0011] Preferably, the second connecting steel component includes a connecting block and a first connecting steel plate; one end of the connecting block is fixed to the top of the second concrete component; the first connecting steel plate consists of two pieces arranged in parallel, the first first connecting steel plate is vertically fixed to the bottom of the square tube, the second first connecting steel plate is fixedly connected to the other end of the connecting block, and the two first connecting steel plates are attached vertically and bolted together by high-strength bolts.

[0012] The beneficial effect of adopting the above technical solution is that, while the second concrete component can be detachably connected to the bottom of the square tube, the second concrete component can effectively support the square tube through the first connecting steel plate.

[0013] Preferably, the connecting steel component three includes an I-beam and a second connecting steel plate; the I-beam consists of two pieces arranged opposite to each other, one of which is vertically fixed to the first wall surface, and the other is fixedly connected to the concrete component three; the second connecting steel plate consists of two pieces arranged in parallel, and the two second connecting steel plates are respectively fixed to the corresponding ends of the two I-beams, and the two are bolted together by high-strength bolts.

[0014] The beneficial effect of adopting the above technical solution is that, unlike the connection methods of connecting steel parts one and two, the connection strength between the concrete component three and the square tube is higher through the connecting steel part three formed by the I-beam and the second connecting steel plate.

[0015] Preferably, a concrete component steel structure connection node further includes a concrete component four, which is arranged on the front side of the square tube. The outer side wall of the square tube has a second wall surface arranged perpendicular to the first wall surface, and the concrete component four is installed on the second wall surface by connecting steel component four.

[0016] Preferably, the connecting steel component four includes channel steel and a third connecting steel plate; the channel steel consists of two pieces, one end of each channel steel is fixed to the concrete component four, the two channel steels are arranged in parallel with their U-shaped openings far apart from each other, and the two channel steels are arranged at intervals to form a limiting joint between them; the third connecting steel plate is vertically fixed to the second wall surface, and the third connecting steel plate is inserted into the limiting joint from the other end of the two channel steels and welded to the limiting joint for fixation.

[0017] The beneficial effect of adopting the above technical solution is that the concrete component can be firmly and securely fixed to the second wall of the square tube by connecting the steel component.

[0018] Preferably, concrete component one, concrete component two, concrete component three and concrete component four are all integral structures formed by steel reinforcement and concrete pouring. Attached Figure Description
