Description

Technical Field

[0001] The present invention relates to a decorative line connection device for the facade of an assembled building. Background Art

[0002] In recent years, assembled buildings have become an important way for the transformation and upgrading of the construction industry in China due to their many advantages, and have been encouraged by government management departments everywhere and developed rapidly. Green buildings and assembled buildings are being promoted to an unprecedented new height in the construction development of China.

[0003] However, assembled buildings, especially concrete assembled buildings, also have their shortcomings compared with traditional cast-in-place concrete buildings due to the limitations of existing technical means. One of the more serious problems currently exposed is the monotonous facade and uniform shapes. The reason is mainly that the exterior wall components of concrete assembled buildings are all prefabricated in factories and are connected and installed on-site through sleeve grouting or secondary casting. The prefabricated exterior wall components are integrated with thermal insulation structures before leaving the factory (sandwich precast concrete exterior wall panels, abbreviated as sandwich PC panels), that is, the prefabricated exterior wall components include a concrete wall, a thermal insulation layer, and an outer leaf panel connected from the inside to the outside. The thickness of the outer leaf panel outside the thermal insulation layer is only 60 mm thick, and it is not allowed to chisel holes or grooves to prevent damage to the integrity of the outer leaf panel. If traditional GRC decorative lines or EPS decorative lines need to be installed, they all require technical means of bonding and anchoring. Once anchored, it will damage the outer leaf panel of the prefabricated exterior wall component, and even the thermal insulation layer, posing a potential water leakage risk. If the outer decorative materials are installed by bonding instead of traditional mechanical connection or anchoring means during the later stage, there will be a great risk of falling off. As a result, the exterior facade of concrete assembled buildings cannot be decorated with traditional GRC decorative lines or EPS decorative lines, and the exterior facade is monotonous and lacks rich shapes. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies existing in the prior art. The present invention provides a decorative line connection device for the facade of an assembled building.

[0005] The present invention is achieved through the following technical solutions:

[0006] A decorative line connection device for the facade of an assembled building, which includes a connection component and an installation component. One end of the connection component is arranged in the construction joint of the prefabricated exterior wall component, and the other end of the connection component extends out of the outer surface of the prefabricated exterior wall component and is connected to the installation component. The installation component is used to connect with the decorative line.

[0007] Further, one end of the connection component away from the installation component has a hook portion, and the hook portion is used to connect with a fixing component inside the prefabricated exterior wall component.

[0008] Further, the hook portion is used to hook the steel bars or grouting sleeves inside the precast exterior wall component.

[0009] Further, the connecting component further includes a screw rod and a nut. One end of the screw rod extends into the precast exterior wall component and is connected to the hook portion, and the other end of the screw rod passes through the installation component and is connected to the nut.

[0010] Further, the installation component is connected to the connecting component and extends outward along the radial direction of the connecting component.

[0011] Further, the installation component fits and abuts against the outer side of the outer leaf panel.

[0031] The descriptions of the following embodiments refer to the attached drawings to exemplify specific embodiments in which the present invention can be implemented.

[0032] Embodiment 1

[0033] As Figure 1 and Figure 2 shown, this embodiment discloses a connecting device for decorative lines on the facade of a prefabricated building. The connecting device for decorative lines on the facade of the prefabricated building includes a connecting component 1 and an installation component 2. One end of the connecting component 1 is arranged in the construction joint 104 of the prefabricated exterior wall component 10, and the other end of the connecting component 1 extends out of the outer surface of the prefabricated exterior wall component 10 and is connected to the installation component 2. The installation component 2 is used to connect to the decorative line 20.

[0034] By embedding the connecting component 1 in the construction joint 104, using the part of the connecting component 1 that is completely connected to the prefabricated exterior wall component 10 to connect to the installation component 2, and then connecting to the decorative line 20 through the installation component 2, the installation of the decorative line 20 is realized, thus ensuring the integrity of the outer panel 103 in the prefabricated exterior wall component 10 and effectively avoiding chiseling holes and grooving on the outer panel 103. At the same time, the decorative line 20 will not be directly installed on the prefabricated exterior wall component 10 but directly installed on the installation component 2, effectively strengthening the connection strength of the decorative line 20, and the construction process is simple and easy to operate, with prominent and obvious effects, which has a positive promoting effect on the improvement and popularization of the building prefabrication process.

[0035] Anchoring connection and / or bonding can be adopted between the installation component 2 and the decorative line 20. Through the anchoring connection between the installation component 2 and the decorative line 20, the installation connection strength of the decorative line 20 is effectively strengthened, and the risk of the decorative line 20 detaching is avoided. Among them, a certain building adhesive can be applied to the contact part between the decorative line 20 and the prefabricated exterior wall component 10.

[0036] One end of the connecting member 1 away from the mounting member 2 has a hook portion 11, and the hook portion 11 is used to connect with the fixing member in the precast exterior wall member 10. The hook portion 11 is placed in the construction joint 104 between two precast exterior wall members 10. Through the hook portion 11, the connection strength between the connecting member 1 and the precast exterior wall member 10 will be effectively enhanced, greatly improving the stability of the decorative line connection device on the facade of the prefabricated building.

[0037] The interior of the precast exterior wall member 10 has steel bars, and there is also a grouting sleeve in the construction joint 104 between two precast exterior wall members 10. The grouting sleeve will be sleeved on the steel bars of the two precast exterior wall members 10, and then during the grouting construction, the grouting sleeve will be integrated with the two precast exterior wall members 10 and precast in the construction joint 104. The fixing member can be a steel bar or a grouting sleeve. The hook portion 11 is used to hook the steel bar or the grouting sleeve in the precast exterior wall member 10. By hooking the steel bar or the grouting sleeve with the hook portion 11, the decorative line connection device on the facade of the prefabricated building is very convenient to use and has high stability.

[0038] In this embodiment, the connecting member 1 may further include a screw 12 and a nut 13. One end of the screw 12 extends into the precast exterior wall member 10 and is connected to the hook portion 11, and the other end of the screw 12 passes through the mounting member 2 and is connected to the nut 13. The mounting member 2 has a through hole, and the screw 12 passes through the through hole of the mounting member 2 and is connected to the nut 13, which will realize the connection between the connecting member 1 and the mounting member 2. By rotating the nut 13, the detachable connection between the connecting member 1 and the mounting member 2 can be realized. The connection is very convenient to use, and by rotating the nut 13, it will tightly abut against the mounting member 2, realizing high stability of the decorative line connection device on the facade of the prefabricated building. Of course, in other embodiments, the connecting member 1 and the mounting member 2 can also be connected in other ways, as long as the connection between the connecting member 1 and the mounting member 2 can be ensured.

[0039] The mounting member 2 fits and abuts against the outer side of the outer leaf panel 103. By tightening the nut 13, the mounting member 2 will tightly fit and abut against the outer side of the outer leaf panel 103. The mounting member 2 will be able to block the through holes in the concrete wall 101, the insulation layer 102 and the outer leaf panel 103 of the precast exterior wall member 10, strengthening the protection effect on the precast exterior wall member 10 and effectively avoiding the potential water leakage problem.

[0040] The mounting member 2 is connected to the connecting member 1 and extends outward along the radial direction of the connecting member 1. By extending outward along the outer surface of the precast exterior wall member 10, the mounting member 2 can effectively increase the protection area and further strengthen the protection effect.

[0041] Among them, the material of the installation component 2 is a heat-insulating material. The heat-insulating performance of the precast exterior wall component 10 can be effectively enhanced through the installation component 2. Preferably, the material of the installation component 2 is a graphene heat-insulating material. With the graphene heat-insulating material, while ensuring heat insulation, the fire resistance reaches Class A2, and there is no need to add other materials to enhance the strength and fire resistance.

[0042] When the decorative line connection device for the exterior facade of the prefabricated building in this embodiment is used in construction, it includes the following steps:

[0043] Step 1, before the sleeve grouting operation of two precast exterior wall components 10, the hook portion 11 on the connection component 1 will be connected to the steel bar or the grouting sleeve in the construction joint 104, and a part of the screw 12 on the connection component 1 extends out of the construction joint 104;

[0044] Step 2, perform sleeve grouting construction according to the conventional requirements, so that a part of the structure of the connection component 1 is integrated with the building;

[0045] Step 3, connect the installation component 2 to the exposed screw 12 of the connection component 1;

[0046] Step 4, connect the decorative line 20 to the installation component 2.

[0047] Embodiment 2

[0048] As Figure 3 shown, the same parts of the structure of the decorative line connection device for the exterior facade of the prefabricated building in this embodiment as those in Embodiment 1 will not be repeated, and only the differences will be described. The specific structures of the installation component 2 and the decorative line 20 in this embodiment are different from those in Embodiment 1. The shape of the installation component 2 can be in the form of a block, a plate, etc., and the specific structure of the installation component 2 is not limited here and can be designed accordingly according to the specific structure of the decorative line 20.

[0049] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
