Embodiment 1

[0028] refer to figure 1 and figure 2 , an assembled keel disclosed in this embodiment is integrally formed by a base part 01, a bent part 02 and a flange 03, the bent part 02 includes a first bent part 21 and a second bent part 22, the first bent part 21 is located on both sides of the base 01 and forms a bending angle of 90° with the base 01, the second bending part 22 is located in the middle of the base 01, and the second bending part 22 is bent inward to form a ridge 221 and a connecting edge 222 The connecting edge 222 is located on both sides of the ridge 221 and connects with the base 01. The connecting edge 222 forms a bending angle of 90-130° with the base 01 or the ridge 221. In this embodiment, a second bending is designed in the middle of the base 01 The part 22 changes the overall planar structure of the base 01 and increases the out-of-plane rigidity of the base 01. Therefore, the second bending part 22 can be used to buffer the pressure from both sides of the...

[0034] refer to Figure 5 and Figure 6 , an assembled keel disclosed in this embodiment is integrally formed by a base part 01, a bent part 02 and a flange 03, the bent part 02 includes a first bent part 21 and a second bent part 22, the first bent part 21 is located on both sides of the base 01 and forms a bending angle of 90° with the base 01, the second bending part 22 is located in the middle of the base 01, and the second bending part 22 is bent inward to form a ridge 221 and a connecting edge 222 The connecting edge 222 is located on both sides of the ridge 221 and connects with the base 01. The connecting edge 222 forms a bending angle of 90-130° with the base 01 or the ridge 221. In this embodiment, a second bending is designed in the middle of the base 01 The part 22 changes the overall planar structure of the base 01 and increases the out-of-plane rigidity of the base 01. Therefore, the second bending part 22 can be used to buffer the pressure from both sides of the ...

Embodiment 3

[0040] refer to Figure 7 and Figure 8 , an assembled keel disclosed in this embodiment is integrally formed by a base part 01, a bent part 02 and a flange 03, the bent part 02 includes a first bent part 21 and a second bent part 22, the first bent part 21 is located on both sides of the base 01 and forms a bending angle of 90° with the base 01, the second bending part 22 is located in the middle of the base 01, and the second bending part 22 is bent inward to form a ridge 221 and a connecting edge 222 The connecting edge 222 is located on both sides of the ridge 221 and connects with the base 01. The connecting edge 222 forms a bending angle of 90-130° with the base 01 or the ridge 221. In this embodiment, a second bending is designed in the middle of the base 01 The part 22 changes the overall planar structure of the base 01 and increases the out-of-plane rigidity of the base 01.

Abstract

The invention relates to an assembled keel and a use method thereof. The keel is integrally formed by a base part, a bending part and flanges; the bending part comprises first bending part bodies anda second bending part body, the first bending part bodies are located at the two sides of the base part and form a 90-degree bending angle with the base part, and the second bending part is located inthe middle of the base part and bends inwards to form a ridge part and connecting edges; the connecting edges are located at the two sides of the ridge part and connected with the base part, a 90-130-degree bending angle is formed between the connecting edges and the base part or the ridge part, and the flanges are located at the tail ends of all the first bending parts and form a 90-degree flange angle with the connected first bending parts. According to the assembled keel, V-shaped reinforcing ribs at the edge of a rib net are preferably selected and directly installed on the outer surfacesof the first bending parts of the keel through a plurality of fixing bolts, and loosening does not easily occur in this fixing mode; in addition, the second bending part designed in the middle of thebase part is used for buffering the pressure from the two sides of the base part, and in this way, when the external pressure or impact is large, the deformation of the keel is better prevented.

Description

technical field [0001] The invention relates to the technical field of building components, in particular to an assembled keel and a using method thereof. Background technique [0002] The keel is a light-weight steel component formed by cold-bending the steel plate. In recent years, the manufacturing and use technology of the keel has been very mature. As a new type of steel component with higher strength, lighter weight and better performance, its It is widely used in low-rise residential buildings with combined structures, even in multi-storey residential buildings. [0003] When the keel is used as a wall component support, it is usually necessary to weld the clips on the keel before installing the reinforcement mesh. This not only makes the assembly troublesome, time-consuming and laborious, but also the residual stress after welding is difficult to eliminate, and it is easy to damage the overall structure of the keel Intensity, the supporting force of the building com...
