Description

Technical Field

[0001] The utility model belongs to the technical field of building equipment, and in particular relates to an assembled concrete slab-column connection structure. Background Art

[0002] The slab-column connection structure is the key part connecting the slab and the column, and its connection quality is directly related to the structural safety of the entire building. In prefabricated buildings, the high-strength concrete slab-column connection structure needs to be able to withstand various loads to ensure the stability and safety of the building.

[0003] Although the construction speed of prefabricated buildings is relatively fast, a certain degree of accuracy and convenience must still be ensured during the installation process. The installation deviation and complex installation process in the traditional connection method will affect the construction efficiency and quality. In the traditional connection method, the steel bars at the nodes are often too dense and cross-linked, which not only increases the difficulty of construction and makes the arrangement and fixing of steel bars more complicated, but also affects the pouring and vibration density of concrete. The dense crossing of steel bars will also make it difficult for concrete to fully fill the node area, thereby affecting the overall performance and durability of the node. Utility Model Content

[0012] There is a step-shaped fracture between the limiting parts of the structural beams on both sides, the fixing plates are located on both sides of the fracture, and ribs are provided on both sides of the fixing plates at the bottom of the limiting part of the structural beam. The ribs are triangular in shape, one right-angle side of the ribs is connected to the limiting part of the structural beam, and the other right-angle side is abutted against the hollow bottom column.

[0013] The fixing plate is L-shaped, and the fixing plates on both sides of the fracture are opposite to each other. The clamp includes a frame and a pressure plate.

Figure 5 As shown, the positioning edge 36 is located between the top of the hollow bottom column 1 and the bottom of the hollow connecting column 2.

[0055] The fixing plate 35 is L-shaped, and the fixing plates 35 on both sides of the fracture are opposite to each other. The clamp 34 includes a frame 341 and a pressure plate 342. One end of the frame 341 is clamped on the fixing plate 35 on one side, and the other end is connected to the pressure plate 342 by bolts.

[0057] Example 5

[0058] In the above-mentioned embodiment, the steel bars at the nodes of the traditional connection method are often too dense and cross, which not only increases the difficulty of construction, but also affects the pouring and vibration density of concrete. Therefore, on the basis of embodiment 3, this embodiment is provided with a connecting part 5 in the connecting sleeve 3, and the connecting part 5 is located on both sides of the inner part of the hollow column limit part 31, such as Fig. 9 As shown, the connection part 5 includes a connecting plate 51 and a connecting rod 52 connected to each other. The connecting plate 51 is located at the upper and lower ends of the connecting rod 52 and is horizontally arranged.

[0061] Compared with the prior art, the connecting portion 5 provided in the connecting sleeve 3 enables the steel bars in the hollow bottom column 1 and the hollow connecting column 2 to be connected in an orderly manner through the connecting portion 5, effectively avoiding the dense crossing of the steel bars at the nodes, thereby reducing the construction difficulty. At the same time, it ensures that the pouring and vibration of the concrete can be carried out smoothly, improves the density of the concrete and the quality of the overall structure. During construction, it is only necessary to insert the steel bars into the corresponding steel bar holes 511 for fixing, without complicated operations or additional tools and equipment. The simplified construction process not only improves the construction efficiency, but also reduces the construction cost.
