Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and particularly relates to a combined prefabricated component. Background Art

[0002] In the construction industry, architectural lines are an important part of decoration and structure. The quality of their production and installation directly affects the aesthetics, durability and safety of the building. Traditionally, the production and installation of architectural lines are mostly done by on-site casting or masonry. Although this method meets construction needs to a certain extent, it has many disadvantages.

[0003] First, on-site pouring or masonry construction methods are time-consuming and inefficient. From material preparation to on-site construction and maintenance, the entire process requires a lot of manpower, material resources, and time. In addition, on-site construction conditions are complex and changeable. Factors such as weather and site conditions are often difficult to control, which can easily affect the construction progress and even cause delays.

[0004] Secondly, on-site construction quality is difficult to control stably. Due to the uncertainty of the construction environment and the differences in the skill levels of construction workers, traditional construction methods are often rough in the treatment of joints, and the stability and integrity of the connections are difficult to ensure. This not only affects the aesthetics of the building, but also poses potential safety hazards to the long-term use of the building.

[0005] To overcome the shortcomings of traditional construction methods, prefabricated component technology has emerged. Prefabricated components are produced in a standardized manner in factories, which can effectively ensure the quality and dimensional accuracy of the components and reduce the complexity and uncertainty of on-site construction.

[0006] However, the existing technology still has some shortcomings in the connection method of prefabricated lines. Common connection methods such as welding and bolt connection, although they can achieve the connection function to a certain extent, are time-consuming and labor-intensive to install, resulting in low efficiency in the installation of prefabricated lines.

[0007] Therefore, it is necessary to develop a new type of building line connection method to overcome the shortcomings of the existing technology and improve the connection quality and construction efficiency of building lines. Utility Model Content

It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0029] like Figure 1-5As shown, a prefabricated component for assembly includes a connecting plate 3 and two prefabricated concrete lines 2, the lower ends of both sides of the connecting plate 3 are fixedly connected with a plurality of steel bars 7, a plurality of circular reserved holes 12 are opened inside the prefabricated concrete line 2, the steel bars 7 located on both sides of the connecting plate 3 are respectively inserted into the circular reserved holes 12 on the prefabricated concrete line 2, a plurality of drainage grooves 6 are opened inside the prefabricated concrete line 2, the upper end of the drainage groove 6 is open, the circular reserved hole 12 is connected to the lower end of the drainage groove 6 away from one end of the connecting plate 3, a drainage groove 2 10 and a circular reserved hole 2 13 are further opened inside the prefabricated concrete line 2, the upper end of the drainage groove 2 10 is open, the rear end of the circular reserved hole 2 13 is open, the lower end of the drainage groove 2 10 is connected to the front end of the circular reserved hole 2 13, a steel bar 2 11 is inserted into the circular reserved hole 2 13, and the end of the steel bar 2 11 away from the prefabricated concrete line 2 is fixedly connected to the wall 1;

[0030] During use, the staff will insert the steel bars 7 located at the lower ends of both sides of the connecting plate 3 into the inside of the circular reserved hole 12 to combine the precast concrete lines 2, and at the same time place the connected connecting plate 3 and precast concrete lines 2 on the outside of the wall 1, and insert the steel bars 11 fixedly connected to the outside of the wall 1 into the inside of the circular reserved hole 2 13 to complete the assembly of the wall 1, the precast concrete lines 2, and the connecting plate 3. At that time, the construction workers can pour the prepared self-compacting concrete into the drainage trough 1 6 and the drainage trough 2 10, and flow through the drainage trough 1 6 and the drainage trough 2 10 to the circular reserved hole 12 and the circular reserved hole 2 13 to fill the gaps around the steel bars 11 and the steel bars 7. When the concrete solidifies, the connection stability between the combined prefabricated parts is increased.

[0031] like Figure 1-3 As shown, a pouring hole 2 9 is opened at the upper end of the precast concrete line 2, and the lower end of the pouring hole 2 9 is connected to the upper end of the drainage trough 2 10. When in use, the upper opening area of ​​the drainage trough 2 10 is enlarged by the pouring hole 2 9, so that the concrete can more conveniently enter the interior of the drainage trough 2 10.

[0032] like Figure 1-3 As shown, a pouring hole 4 is provided at the upper end of the precast concrete line 2, and the lower end of the pouring hole 4 is connected to the upper end of the drainage groove 6. When in use, the drainage groove 6 increases the upper opening area of ​​the pouring hole 4, making it easier for concrete to enter the pouring hole 4.

[0033] like Figure 3-4 As shown, a sealing gasket 5 is fixedly connected to one end of the precast concrete line 2 close to the connecting plate 3, and the sealing gasket 5 is located between the connecting plate 3 and the precast concrete line 2. When in use, the circular hole 8 can effectively reduce the mortar loss of the self-compacting concrete during pouring and connection, thereby reducing costs.

[0034] like Figure 1-5 As shown, multiple circular holes 8 are opened on the side of the steel bar 7. When in use, the circular holes 8 provide more attachment points for the self-compacting concrete, so that the concrete can better wrap the steel bar. During the pouring process, the concrete can flow into the circular holes 8 and form a mechanical bite with the steel bar, thereby greatly enhancing the bonding force between the concrete and the steel bar 7, and effectively increasing the connection stability between the wall 1, the precast concrete line 2, and the connecting plate 3.

[0035] The inner diameter of the circular reserved hole 12 is 1.5-2 times the outer diameter of the steel bar 7, and the inner diameter of the circular reserved hole 2 13 is 1.5-2 times the outer diameter of the steel bar 2 11.

By setting the inner diameter of the circular reserved hole 2 13 and the outer diameter of the steel bar 2 11, a channel for concrete flow is provided between the circular reserved hole 2 13 and the steel bar 2 11.

[0036] like Figure 1-5 As shown, the drainage groove 1 6 and the circular reserved hole 12 form an angle of 140 degrees, and the drainage groove 2 10 and the circular reserved hole 2 13 form an angle of 140 degrees. When in use, the 140-degree angle setting can provide a guide for the flow of self-compacting concrete. During the pouring process, the concrete can flow more smoothly to the circular reserved hole 12 and the circular reserved hole 2 13, reducing the flow obstruction or blockage caused by improper angles.

[0037] The working principle of this utility model is:

[0038] The staff will respectively insert the steel bars 7 located at the lower ends of both sides of the connecting plate 3 into the inside of the circular reserved hole 12 to assemble the precast concrete lines 2, and at the same time place the connected connecting plate 3 and the precast concrete lines 2 on the outside of the wall 1, and insert the steel bars 11 fixedly connected to the outside of the wall 1 into the inside of the circular reserved hole 2 13 to complete the assembly of the wall 1, the precast concrete lines 2, and the connecting plate 3. At that time, the construction workers can pour the prepared self-compacting concrete into the inside of the drainage groove 1 6 and the drainage groove 2 10, and the concrete will flow through the drainage groove 1 6 and the drainage groove 2 10 to the circular reserved hole 12 and the circular reserved hole 2 13 to fill the gaps around the steel bars 2 11 and the steel bars 7. When the concrete solidifies, the connection stability between the assembled prefabricated parts is increased.

[0039] In summary, the present technical solution first uses steel bars 1 7 and steel bars 2 11 to install the precast concrete lines 2 and the connecting plates 3, and after the installation is completed, concrete is poured around the steel bars 1 7 and the steel bars 2 11 through the drainage trough 1 6 and the drainage trough 2 10, so that the precast concrete lines 2 and the connecting plates 3 can be quickly and stably fixed to the outside of the wall 1 through the concrete and the steel bars 1 7 and the steel bars 2 11.
