[0002] Prefabricated buildings are a current development trend in the construction industry, such as prefabricated stairs, prefabricated walls, etc. They are composed of multiple components assembled together, and joints will inevitably occur at the splicing positions.

[0003] Currently, for sealing joints, the practices of directly filling joints with mortar or filling joints with PE materials + caulking are mostly adopted. These practices not only have complex construction but also easily result in imperfect joint sealing due to thermal expansion and contraction of the filling materials, causing cracks in the upper decorative materials and other drawbacks. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a caulking structure for the joints of prefabricated components, so as to simplify the construction process of joint sealing and ensure the reliability of joint sealing.

Hanging ears are arranged on both sides of the outer framework, and a matching outer framework protrusion and an outer framework groove are respectively arranged at both ends of the outer framework; matching inner strip protrusions and inner strip grooves are respectively arranged at both ends of the inner strip.

[0006] Further, the hanging ears are integrally formed with the outer framework.

[0007] Further, the outer framework is in an inverted "L" shape.

[0008] Further, the inner strip is fixedly embedded in the upper part of the outer framework.

[0009] Further, the top of the inner strip is flush with the top of the outer framework.

[0010] Further, the area surrounded by the inner strip and the outer framework forms a cavity below.

[0011] The beneficial effects of the utility model: The caulking structure for the joints of prefabricated components of the utility model includes an outer framework and an inner strip fixedly embedded in the outer framework. Hanging ears are arranged on both sides of the outer framework, and a matching outer framework protrusion and an outer framework groove are respectively arranged at both ends of the outer framework; matching inner strip protrusions and inner strip grooves are respectively arranged at both ends of the inner strip; by adopting the caulking structure for the joints of prefabricated components of the present application, the construction process of joint sealing is simplified, and the reliability of joint sealing is ensured.

[0021] The present invention will be described in detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 7 As shown: This embodiment provides a caulking structure for the joints of assembled components, including an outer frame 1 and an inner caulking strip 2 fixedly embedded with the outer frame, wherein the two sides of the outer frame are provided with hanging ears 1-1, and the two ends of the outer frame are respectively provided with matching outer frame protrusions 1-2 and outer frame grooves 1-3; the two ends of the inner caulking strip are respectively provided with matching inner caulking strip protrusions 2-1 and inner caulking strip grooves 2-2.

[0023] In this embodiment, the two sides of the outer frame are bent to form integral hanging ears; the outer frame is in an inverted "J" shape; the inner embedding strip is embedded and fixed on the upper part of the outer frame; the top of the inner embedding strip is flush with the top of the outer frame; the inner embedding strip is a flexible filling structure with good coordinated deformation performance; the area below the inner embedding strip and the outer frame forms a cavity 3 to meet the deformation requirements.

[0024] When applied, such as Figures 3 to 6As shown, the outer frame protrusion of one outer frame matches and fits with the outer frame groove of another outer frame, and synchronously, the inner lining protrusion of one inner lining also matches and fits with the inner lining groove of another inner lining. In this way, multiple caulking structures can be assembled, thereby changing the overall length and shape of the assembled caulking structure to meet the sealing requirements of different lengths of caulking. In actual needs, the caulking structure can be as follows Figure 5 The curved section structure shown in FIG. Figure 6 The straight section structure shown.

[0025] The following is a further explanation of the specific construction method:

[0026] like Figure 7 As shown, the caulking structure is installed at the joint of two components 4. The surface of the component is provided with a hanging ear installation groove 4-1. The depth of the hanging ear installation groove is slightly larger than the size of the hanging ear 1-1. The hanging ear is embedded in the hanging ear installation groove to achieve a close fit with the component. The caulking structure fills and closes the joint between the components. For components with height differences on both sides of the joint, a deep groove should be cut in the higher side component, the hanging ear should be further bent and embedded in the deep groove of the higher side component, and a shallow groove should be cut in the lower side component, and the hanging ear on the other side should be embedded in the shallow groove to achieve adjustment. Both the external frame and the internal caulking strip have a certain deformation capacity. By adjusting the depth of the slit groove, a smooth caulking of components with a certain height difference can be achieved.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
