Description

Technical Field

[0001] The utility model relates to the technical field of fair - faced concrete installation, and particularly relates to a connection node of fair - faced concrete components. Background Art

[0002] With the development of fair - faced concrete technology, more and more public buildings choose to use fair - faced concrete as the exterior facade decoration. Its overall appearance is relatively high - end and grand. At the same time, due to the large difficulty in controlling the construction quality of cast - in - place fair - faced concrete, factory - precast fair - faced concrete has emerged, and the method of transporting it to the construction site and connecting it with structural components is adopted. The traditional method is to reserve steel bars for both precast components and cast - in - place components, and then carry out welding or mechanical connection on - site, and then cast - in - place concrete. Since there are many steel bar connections in this method, the positioning and alignment of steel bars will consume a lot of time, and the welding quality is affected by various factors, resulting in very difficult construction when connecting precast components with structural components, and the construction quality and construction efficiency cannot be effectively guaranteed. Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the utility model provides a connection node of fair - faced concrete components, which solves the problem of low efficiency when connecting precast fair - faced concrete precast components with structural beams in the prior art.

[0018] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

[0019] Such as Figure 1As shown in Fig. -4, an embodiment of the utility model provides a connection node for fair - faced concrete components, including a precast component 1 and a structural beam 4. A connecting steel beam 2 is fixedly arranged on one side of the precast component 1. A plurality of groups of anchor bolts 3 are symmetrically arranged on both side walls of the connecting steel beam 2. A groove is opened at one end of the structural beam 4 for the connecting steel beam 2 to be inserted into. During construction, first, the anchor bolts 3 are welded on both sides of the connecting steel beam 2. In this embodiment, two rows of anchor bolts 3 are arranged on each side of the connecting steel beam 2, and the number of anchor bolts 3 in each row is four. The same arrangement is made on the other side of the connecting steel beam 2. Then, the precast component 1 is fabricated. When fabricating the precast component 1, one end of the connecting steel beam 2 is embedded into the precast component 1, so that after the precast component 1 is formed, it is fixed on one side of the precast component 1. Then, the structural beam 4 is poured. When pouring the structural beam 4, a groove is reserved at one end of the structural beam 4. In this embodiment, the width of the groove is about 10 CM wider than the width of the integrated structure composed of the connecting steel beam 2 with anchor bolts 3. When connecting the precast component 1 and the structural beam 4, first, the inner wall of the groove of the structural beam 4 is roughened. Then, the precast component 1 is hoisted and positioned, so that the connecting steel beam 2 is inserted into the groove of the structural beam 4, and the end of the structural beam 4 with the groove is closely attached to the outer wall of the precast component 1. After confirming the accurate position, concrete can be poured into the groove. Finally, wait for the concrete to solidify. Workers do not need to weld the steel bars on the precast component 1 and the steel bars on the structural beam 4 by welding. They only need to insert the connecting steel beam 2 on one side of the precast component 1 into the groove of the structural beam 4, and then pour concrete. The anchor bolts 3 on both sides of the connecting steel beam 2 can increase the anchoring force and transfer the load, and prevent relative slip between the structural beam 4 and the connecting steel beam 2. By this method, while improving the connection efficiency when connecting the fair - faced concrete precast component 1 and the structural beam 4, the connection strength between the two also meets the quality requirements, ensuring the safety and reliability of the building.

[0020] As Figure 1 —4 shows, further, it also includes connecting bars 5. A number of connecting bars 5 are equally spaced on two opposite inner walls of the groove of the precast beam. Specifically, in this embodiment, two rows of connecting bars 5 are arranged on both opposite inner walls of the groove of the structural beam 4. The connecting bars 5 are connected to the inner wall of the groove of the structural beam 4 by embedding. The connecting bars 5 play the role of shear keys. After pouring concrete into the groove, the connecting bars 5 are inserted into the concrete, increasing the contact area between the structural beam 4 and the concrete, making the connection between the structural beam 4 and the concrete more stable. At the same time, it can effectively transfer and disperse the shear force, reduce stress concentration, and prevent cracking or slipping between the structural beam 4 and the concrete.

[0021] Furthermore, each connecting rib 5 is located between two anchor bolts 3. Specifically, after connecting the precast member 1 to the structural beam 4, each connecting rib 5 and the anchor bolts 3 are staggered. This staggering is in the horizontal direction and vertically upward. This not only improves the strength after the concrete solidifies but also enhances the connection strength between the structural beam 4 and the precast member 1 after connection.

[0022] As Figure 4 shown, furthermore, the distance from the top of the precast member 1 to the bottom of the connecting steel beam 2 is the same as the depth of the groove of the structural member. By controlling the distance between the connecting steel beam 2 and the precast member 1, after connecting the precast member 1 to the structural beam 4, the top of the precast member 1 and the top of the structural beam 4 are on the same horizontal plane, which is more aesthetically pleasing.

[0023] As Figure 1 shown in Figure 4, furthermore, it also includes a water stop plate 6. There are two water stop plates 6, and the two water stop plates 6 are respectively arranged on the two inner walls of the groove of the structural beam 4. In this embodiment, the two water stop plates 6 are arranged opposite to each other, and both water stop plates 6 are located between the two connecting ribs 5. The water stop plate 6 blocks the water entering through the joint between the concrete and the structural beam 4, preventing it from continuing to penetrate downward, thereby ensuring the connection quality between the structural beam 4 and the precast member 1.

[0024] As Figure 3 shown, furthermore, the water stop plate 6 is U-shaped, and one side of each water stop plate 6 facing away from the precast beam is located between the two anchor bolts 3. Specifically, the U-shaped water stop plate 6 can significantly improve the waterproof performance of the construction joint. The U-shaped water stop plate 6 has a certain elasticity and can adapt to the deformation caused by factors such as temperature change, load action, and foundation settlement of the overall structure, always playing a good water stop effect.

[0025] As Figure 3 shown in Figure 4, furthermore, a convex block 7 is provided on the side wall of the structural beam 4 facing the precast member 1, and a positioning groove 8 for inserting the convex block 7 is provided on the side wall of the precast member 1 facing the structural beam 4. By providing the convex block 7 on the structural beam 4, when aligning the structural beam 4 and the precast member 1, the convex block 7 of the structural beam 4 is pre-inserted into the positioning groove 8 of the precast member 1, thereby playing a positioning role in the connection between the two.

[0026] As Figure 1 and 3 shown, furthermore, the connecting steel beam 2 is an I-beam. As a common material in the construction field, the I-beam is easy to find, has a high cost performance, and the I-beam itself has high strength and stability and can bear a large load. Used as the connection structure between the precast member 1 and the structural beam 4, it can bear strong bending and shear forces and is suitable for the high-strength connection between the two.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
