Description

Technical Field

[0001] This utility model relates to a connection structure and connector, specifically a high-precision connection structure and connector for prefabricated houses, belonging to the technical field of prefabricated house connection structures, and is particularly suitable for multi-story reinforced concrete prefabricated houses. Background Technology

[0002] Prefabricated houses are residences where some or all of the building components are prefabricated in a factory, transported to the construction site, and then assembled into a complete house using reliable connection methods. These components typically include beams, slabs, columns, and architectural finishing accessories, and are made primarily of concrete, steel, or other materials. Prefabricated houses have a wide range of applications, including commercial, residential, and industrial sectors. In the residential sector, prefabricated houses are becoming an increasingly popular choice due to their efficiency, environmental friendliness, and energy savings. Meanwhile, in the commercial and industrial sectors, prefabricated houses are also favored for their rapid construction and flexible assembly capabilities.

[0003] Currently, there are many types of prefabricated houses produced in factories, especially prefabricated houses that are produced entirely on a large scale. These houses also have various fixing methods, but the main methods of assembling embedded parts and welding them after assembly, and fastening them with pre-installed bolts, all have some shortcomings:

[0004] Taking precast reinforced concrete houses as an example, if welding is used for fixing, a significant problem will be faced: concrete itself is not resistant to high temperatures, so the high temperature generated during the welding process can easily cause the concrete to crack. This will not only affect the welding quality, but also directly damage the overall structure of the building and shorten its service life. Therefore, although welding has the advantage of being easy to operate in some cases, it is inadequate in fixing precast reinforced concrete houses.

[0005] On the other hand, if the method of fixing with pre-embedded bolts is adopted, although the impact of high temperature on concrete can be avoided, this method also has the problem of difficulty in ensuring the accuracy of adjacent pre-embedded parts. In actual operation, due to construction errors or improper design, the pre-embedded bolts are often misaligned. At this time, the construction workers have to abandon some pre-embedded bolts and adopt other fixing methods. This practice will undoubtedly weaken the overall performance of the building and reduce its stability and safety.

[0006] To address this, a high-precision connection structure and connectors for prefabricated houses are proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a high-precision connection structure and connectors for prefabricated houses, so as to solve one of the problems mentioned in the background art.

[0008] This utility model is implemented by the following technical solution: a high-precision connection structure and connectors for prefabricated houses, including a first ground beam and a second ground beam. The first ground beam has pre-embedded connecting steel bars embedded at equal intervals inside. The second ground beam is cast on the first ground beam to form a stepped ground beam. The top of the pre-embedded connecting steel bars is embedded inside the second ground beam.

[0009] A wall is provided on the first ground beam. Countersunk holes are evenly opened inside the wall. A connecting component is installed inside the countersunk hole. The end of the connecting component away from the wall is embedded in the interior of the second ground beam. A reinforcing component is pre-embedded inside the wall. The end of the reinforcing component away from the wall is embedded in the interior of the second ground beam.

[0010] As a further preferred embodiment of this technical solution: the reinforcement component includes a first insert plate, a connecting sleeve, a connecting screw, and a second insert plate, one end of the connecting sleeve being fixedly connected to the first insert plate, and one end of the connecting screw being fixedly connected to the second insert plate.

[0011] As a further preferred embodiment of this technical solution: the end of the connecting screw away from the second insert plate is threaded into the inside of the connecting sleeve.

[0012] As a further preferred embodiment of this technical solution: both the first insert plate and the connecting sleeve are embedded inside the wall.

[0013] As a further preferred embodiment of this technical solution: both the second interlocking plate and the connecting screw are embedded inside the second ground beam.

[0014] As a further preferred embodiment of this technical solution: the bottom of the wall is attached to the upper surface of the first ground beam, and one side of the wall is attached to the second ground beam.

[0015] A connector includes a connecting assembly comprising a Z-shaped connecting bolt and a connecting nut, the connecting nut being threaded onto the outer wall of the Z-shaped connecting bolt.

[0016] As a further preferred embodiment of this technical solution: one end of the Z-shaped connecting bolt is located inside the countersunk hole, the other end of the Z-shaped connecting bolt is embedded inside the second ground beam, and the connecting nut is located inside the countersunk hole.

[0017] Advantages of this invention: This invention first inserts Z-shaped connecting bolts into the countersunk holes, uses connecting nuts to define the position of the Z-shaped connecting bolts, and then erects the wall. If it is a prefabricated reinforced concrete building, it can be erected first and placed on the first ground beam. After determining the position, the Z-shaped bolts are inserted and fixed with nuts. The second ground beam is then poured on the first ground beam. After the second ground beam is formed, the wall is firmly connected to the second ground beam through the connection of the connecting components and the reinforcing components. Since the second ground beam is directly poured and formed on the connecting components and the reinforcing components, a high-precision connection of the prefabricated wall is achieved, ensuring the accuracy of the wall connection without affecting the strength and lifespan of the structure. After the wall is fixed, the countersunk holes can be smoothed with cement mortar or plaster, thereby improving the aesthetics of the wall. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] Please see Figures 1-8 This utility model provides a technical solution: a high-precision connection structure for prefabricated houses, including a first ground beam 12 and a second ground beam 13. The first ground beam 12 is equidistantly embedded with pre-embedded connecting steel bars 14. The pre-embedded connecting steel bars 14 are pre-embedded during the pouring of the first ground beam 12. After the first ground beam 12 is poured and formed, the pre-embedded connecting steel bars 14 are integrally formed with the first ground beam 12.

[0031] The second ground beam 13 is cast on the first ground beam 12 to form a stepped ground beam. The top of the pre-embedded connecting steel bar 14 is embedded in the interior of the second ground beam 13. The second ground beam 13 is formed by casting on the first ground beam 12. Under the action of the pre-embedded connecting steel bar 14, the connection strength of the two ground beams can be guaranteed.

[0032] A wall 11 is provided on the first ground beam 12. Countersunk holes 17 are evenly provided inside the wall 11. The countersunk holes 17 are reserved when the wall 11 is cast.

[0033] A connecting component 16 is installed inside the countersunk hole 17. The end of the connecting component 16 away from the wall 11 is embedded in the interior of the second ground beam 13. The bottom of the wall 11 is attached to the upper surface of the first ground beam 12, and one side of the wall 11 is attached to the second ground beam 13. The connection between the wall 11 and the second ground beam 13 can be achieved through the connecting component 16.

[0034] A reinforcing component 15 is pre-embedded inside the wall 11. The end of the reinforcing component 15 away from the wall 11 is embedded in the interior of the second ground beam 13. The reinforcing component 15 can enhance the connection strength between the wall 11 and the second ground beam 13.

[0035] During construction, the connecting component 16 is first installed inside the countersunk hole 17, and then the wall 11 is erected. At this time, both the connecting component 16 and the reinforcing component 15 are located on the first ground beam 12. The second ground beam 13 is then poured. After the second ground beam 13 is formed, the wall 11 is tightly connected to the second ground beam 13 under the connection of the connecting component 16 and the reinforcing component 15. Since the second ground beam 13 is directly poured and formed on the connecting component 16 and the reinforcing component 15, a high-precision connection of the precast wall 11 is achieved, ensuring the accuracy of the connection of the wall 11, and without affecting the strength and life of the structure. After the wall 11 is fixed, the countersunk hole 17 can be smoothed with cement mortar or plaster, thereby improving the aesthetics of the wall.

[0036] In this embodiment, specifically: Figure 5 , Figure 8 Another connection method and connector, each with its own advantages, is used. The reinforcement component 15 includes a first insert plate 151, a connecting sleeve 152, a connecting screw 153, and a second insert plate 154. One end of the connecting sleeve 152 is fixedly connected to the first insert plate 151, and one end of the connecting screw 153 is fixedly connected to the second insert plate 154. The end of the connecting screw 153 away from the second insert plate 154 is threaded into the inside of the connecting sleeve 152. The reinforcement component 15 adopts an assembly connection, which is convenient for construction.

[0037] In this embodiment, specifically: the first embedding plate 151 and the connecting sleeve 152 are both embedded inside the wall 11. The first embedding plate 151 and the connecting sleeve 152 are pre-embedded when the wall 11 is poured, so that when the wall 11 is formed, the first embedding plate 151, the connecting sleeve 152 and the wall 11 are integrally formed.

[0038] The second interlocking plate 154 and the connecting screw 153 are both embedded inside the second ground beam 13. Through the cooperation of the second interlocking plate 154, the connecting screw 153, the connecting sleeve 152, and the first interlocking plate 151, the wall 11 can be reinforced.

[0039] A connector includes a connecting assembly 16, which includes a Z-shaped connecting bolt 161 and a connecting nut 162. The connecting nut 162 is threaded onto the outer wall of the Z-shaped connecting bolt 161. One end of the Z-shaped connecting bolt 161 is located inside a countersunk hole 17, and the other end of the Z-shaped connecting bolt 161 is embedded inside a second ground beam 13. The connecting nut 162 is located inside the countersunk hole 17. Through the cooperation of the Z-shaped connecting bolt 161 and the connecting nut 162, the connection between the wall 11 and the second ground beam 13 can be realized.

[0040] In terms of working principle or structural principle, when in use, first insert the Z-shaped connecting bolt 161 into the countersunk hole 17, and use the connecting nut 162 to limit the position of the Z-shaped connecting bolt 161. Then, erect the wall 11. At this time, the Z-shaped connecting bolt 161, the connecting screw 153, and the second interlocking plate 154 are all located on the first ground beam 12. Then, cast the second ground beam 13 on the first ground beam 12. After the second ground beam 13 is formed, the wall 11 and the second ground beam 13 are tightly connected under the connection of the connecting component 16 and the reinforcing component 15, thereby achieving a high-precision connection of the wall 11. Then, use cement mortar or plaster to smooth the countersunk hole 17 to ensure the aesthetics of the wall 11.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
