Description

Technical Field

[0001] This utility model relates to the field of prefabricated component technology, and in particular to a single-sided composite prefabricated component and its vertical connection structure. Background Technology

[0002] Composite walls are a type of wall structure that combines prefabricated components with cast-in-place concrete, and are widely used in prefabricated buildings. Their core feature is that the combination of prefabrication and cast-in-place construction balances construction efficiency with structural integrity.

[0003] The existing composite wall has an unreasonable structure in the cast-in-place zone. If the cast-in-place concrete shrinks, the density of the concrete near the vertical reinforcement will decrease, thereby reducing the connection strength between the cast-in-place concrete and the vertical reinforcement, and thus making the anchorage effect of the cast-in-place zone worse.

[0004] Therefore, this utility model is proposed. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a single-sided composite prefabricated component and its vertical connection structure to solve the technical problems in related technologies.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] According to one aspect of this utility model, a single-sided composite precast component is provided, comprising a component body, the lower part of which has a cast-in-place zone; the bottom of the cast-in-place zone is open from the bottom of the component body, one side of the cast-in-place zone is an open structure for supporting formwork; the sides and bottom of the component body have openings to facilitate the support of the formwork; the top of the cast-in-place zone has vent holes, and below the top are fixing holes for installing the formwork. The inner surface of the top of the cast-in-place zone has a corrugated structure, and the component body contains vertical reinforcing bars, which extend from the troughs of the corrugated structure.

[0008] Optionally, the vent is located at the crest of the wave-shaped structure.

[0009] Optionally, the bottom of the main body of the component is provided with a height adjustment mechanism for adjusting the elevation of the prefabricated component.

[0010] Optionally, the height adjustment mechanism is an adjusting bolt.

[0011] Optionally, the cast-in-place zone includes multiple zones, each of which extends along the length of the precast component to form a continuous cast-in-place area.

[0012] This utility model also provides a vertical connection structure for a single-sided composite precast component. The vertical connection structure includes an upper precast component and a lower precast component. Both the upper and lower precast components are the aforementioned single-sided composite precast components, wherein the vertical reinforcing bars of the lower precast component extend into the cast-in-place area at the bottom of the upper precast component.

[0013] This utility model provides a single-sided composite precast component, including a component body. A wave-shaped structure is constructed on the top surface of the bottom cast-in-place area of ​​the component body. The bottom ends of the vertical reinforcing bars of the component body protrude from the troughs. In this way, even if the cast-in-place concrete shrinks, it will first occur at the crests and will not affect the troughs. Therefore, the density of the concrete near the vertical reinforcing bars will not change, thus avoiding affecting the anchoring effect when connecting the upper and lower precast components.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] This utility model provides a single-sided composite prefabricated component, combined with Figure 1-6 The system includes a main component 1, with a cast-in-place zone 2 at its lower part. The bottom of the cast-in-place zone 2 is connected to the bottom of the main component 1, and one side of the cast-in-place zone 2 is an open structure for supporting formwork. The top of the cast-in-place zone 2 is connected to a concrete pouring channel 3, the upper end of which extends from the top of the main component 1. In use, formwork is erected on the open side of the cast-in-place zone 2, and then concrete is poured into the cast-in-place zone 2 through the concrete pouring channel 3. The concrete forms a bond with the vertical reinforcing bars 4 and horizontal reinforcing bars 5 within the cast-in-place zone 2. After the concrete has solidified, the formwork is removed, thus completing the cast-in-place process.

[0024] The main body 1 has gaps 12 on both sides and at the bottom to facilitate the installation of formwork. Specifically, the main body 1 has narrow gaps 12 on both sides, and the bottom is constructed with gaps 12 starting from the cast-in-place zone 2. The top of the cast-in-place zone 2 has vent holes 6, and below the top are fixing holes 7 for installing formwork. The formwork can be fixed by connecting components such as tie bolts passing through the fixing holes 7. The vent holes 6 can be used to release air during concrete pouring to ensure the internal density of the cast-in-place zone 2.

[0025] The top inner surface of the cast-in-place zone 2 is a corrugated structure 8. The main component 1 contains vertical reinforcing bars 4, which extend from the troughs of the corrugated structure 8. This ensures that even if the concrete is not sufficiently dense and shrinkage occurs, the shrinkage will occur at the top and will not affect the vertical reinforcing bars 4 located in the troughs. Since the vertical reinforcing bars 4 also serve to connect the upper and lower precast components, the anchorage strength of the connection between the upper and lower layers will not be affected by concrete shrinkage. Vent holes 6 are located at the crests of the corrugated structure 8, allowing gas generated during concrete pouring to escape from the top.

[0026] The bottom of the main component 1 is equipped with a height adjustment mechanism for adjusting the elevation of the prefabricated component, which facilitates elevation adjustment during wall assembly. Various mechanisms can be used for the height adjustment; in this embodiment, it is an adjusting bolt 9.

[0027] The cast-in-place zone 2 includes multiple zones, each of which extends along the length of the precast component to form a continuous cast-in-place zone 2 domain, meaning that the cast-in-place zone 2 is relatively long.

[0028] This embodiment also provides a vertical connection structure for single-sided composite precast components. The vertical connection structure includes an upper precast component 10 and a lower precast component 11. Both the upper precast component 10 and the lower precast component 11 are the aforementioned single-sided composite precast components. The vertical reinforcing bars 4 of the lower precast component 11 extend into the cast-in-place area 2 at the bottom of the upper precast component 10, forming an overlap with the vertical reinforcing bars 4 of the upper precast component 10. After pouring concrete, the connection and anchoring between the upper and lower precast components are completed.

[0029] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
