Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated concrete technology, and in particular to a continuous column structure in prefabricated concrete. Background Technology
[0002] In the development of the construction industry, prefabricated buildings have gradually become an important development direction in the construction field due to their advantages such as fast construction speed, controllable quality, energy saving and environmental protection. For low-rise building structures such as small villas, traditional concrete column connection methods have problems such as complex construction, large amount of on-site wet work, and long construction period. For example, when pouring concrete columns on site, a series of tedious procedures are required, such as setting up a large number of formwork, tying steel bars and pouring concrete, and the long concrete curing time affects the construction progress. At the same time, traditional connection methods also have certain limitations in terms of structural integrity and seismic performance.
[0003] Therefore, those skilled in the art have provided a prefabricated concrete continuous column structure to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a prefabricated concrete continuous column structure, which reduces the amount of on-site wet work, avoids complex procedures such as formwork erection and rebar tying, effectively shortens the construction cycle, improves construction efficiency, and reduces labor costs and construction management difficulty.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A prefabricated concrete through-column structure includes a long column mechanism and multiple node connection mechanisms. The long column mechanism includes two through column plates, which are welded perpendicularly to each other to form a "T" shape. Both ends of the two through column plates are fixedly provided with outer connecting plates.
[0007] Furthermore, each of the outer connecting plates is fixedly provided with a node plate, and each of the node plates is provided with a plurality of connecting bolts running through it.
[0008] Furthermore, each of the multiple node connection mechanisms includes a node profile, and each of the multiple node profiles has multiple connection ports inside.
[0009] Furthermore, all of the aforementioned node profiles are fixedly connected to the node plate through the connection port by multiple connecting bolts.
[0010] This utility model has the following beneficial effects:
[0011] 1. This utility model proposes a prefabricated concrete continuous column structure. In this structure, steel sections are connected to the upper and lower concrete columns at the factory to form a continuous column. On-site installation of the concrete beams only requires bolting. Compared to the traditional on-site casting method for concrete columns, this significantly reduces on-site wet work, avoids complex procedures such as formwork erection and rebar tying, effectively shortens the construction cycle, improves construction efficiency, and reduces labor costs and construction management difficulty.
[0012] 2. This utility model proposes a prefabricated concrete continuous column structure. By using steel sections to connect the beam-column joints, the excellent mechanical properties of the steel sections enhance the connection strength and integrity of the joints. This allows the entire continuous column structure to more effectively transfer and disperse stress when bearing vertical and horizontal loads, improving the seismic performance and stability of the building structure, and ensuring the safety and durability of the building.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1: Refer to Figure 1-4 The present invention provides an embodiment of a prefabricated concrete through-column structure, comprising a long column mechanism 1 and multiple node connection mechanisms 2. The long column mechanism 1 includes two through column plates 102, which are welded perpendicularly to each other to form a "T" shape. Both ends of the two through column plates 102 are fixedly provided with outer connecting plates 101. Multiple node plates 104 are fixedly provided on the outside of the multiple outer connecting plates 101. Multiple connecting bolts 105 are passed through the inside of the multiple node plates 104. The multiple node connection mechanisms 2 each include node profiles 201. Multiple connection ports 202 are opened inside the multiple node profiles 201. The multiple node profiles 201 are fixedly connected to the node plates 104 through the connection ports 202 by multiple connecting bolts 105.
[0023] Specifically, both the long column mechanism 1 and the node connection mechanism 2 are standardized components that can be mass-produced in the factory. This modular design facilitates quality control, ensuring the precision and quality consistency of each component, reducing on-site construction errors, and improving the overall quality of the building. The node connection mechanism 2 is tightly connected to the node plate 104 of the long column mechanism 1 via connecting bolts 105. The bolted connection method has well-defined mechanical properties and can withstand large tensile, compressive, and shear forces. When the structure is under stress, it can reliably transmit internal forces, ensuring the safety and stability of the structure under normal use and extreme loads such as earthquakes.
[0024] Example 2: Refer to Figure 5 and 6 This utility model provides another embodiment: a prefabricated concrete through-column structure, including a long column mechanism 1 and multiple node connection mechanisms 2. The long column mechanism 1 includes two through column plates 102, which are welded perpendicularly to each other to form an "L" shape. Outer connecting plates 101 are fixedly installed at both ends of the two through column plates 102. Node plates 104 are fixedly installed on the exterior of each of the multiple outer connecting plates 101, and multiple connecting bolts 105 are passed through the interior of each of the multiple node plates 104. Each of the multiple node connection mechanisms 2 includes a node profile 201, and multiple connection ports 202 are opened inside each of the multiple node profiles 201. The multiple node profiles 201 are fixedly connected to the node plates 104 through the connection ports 202 by multiple connecting bolts 105.
[0025] In Example 2, the "L"-shaped long column mechanism 1 is suitable for corner parts of building structures with special spatial layout requirements. Its principle is similar to Example 1, achieving load transfer through a reliable connection between the node connection mechanism 2 and the long column mechanism 1. The "L"-shaped column structure can better adapt to the spatial needs at building corners, meeting diverse architectural design requirements without changing the basic connection principle and ease of construction. It provides more possibilities for architectural form and space utilization. It has a certain degree of versatility with the components in Example 1; the node connection mechanism 2 and other components are interchangeable. During construction, "T"-shaped or "L"-shaped columns can be flexibly selected according to the actual building layout, reducing the types of molds and components, and facilitating construction management and material procurement.
[0026] Working Principle: In the long column mechanism 1, two central column plates 102 are welded perpendicularly to each other to form a "T" shape, constituting the main structure of the long column. The outer connecting plate 101 provides the installation base for the node connection. The node plate 104 is fixedly connected to the outer connecting plate 101, and the connecting bolts 105 passing through it are used to connect with the node connection mechanism 2. The node profile 201 in the node connection mechanism 2 has a connection port 202 inside. The node profile 201 is fixedly connected to the node plate 104 by the connecting bolts 105 passing through the connection port 202. In actual operation, when the building is subjected to vertical loads, the load is transferred to the node connection mechanism 2 through the concrete beam, and then transferred to the long column mechanism 1 through the connecting bolts 105. Finally, the long column transfers the load to the foundation.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
