A steel plate is fixedly welded to the top of the fixed steel pipe. The plug-in component is placed in a template and cast to form a precast fair-faced concrete component. The diameter of the fixed steel pipe is larger than the diameter of the movable steel pipe. The fixed steel pipe is plugged into the top of the movable steel pipe. Structural adhesive is used to fill the gap between the bottom wall of the precast fair-faced concrete component and the top of the roof filling layer.

[0006] Furthermore, both the movable and fixed steel pipes are galvanized steel pipes. The movable steel pipe has a diameter of 50mm and a height of 50cm, while the fixed steel pipe has a diameter of 80mm and a height of 35cm. The movable steel pipe has a threaded opening at a height of 20cm or less at the bottom.

[0007] Furthermore, the threaded joint has a diameter of 55mm and a height of 20cm. The outer wall of the threaded opening is threaded to the inner wall of the threaded joint. Four steel bars are fixedly welded to the outer side of the bottom end of the threaded joint, and eight steel bars are fixedly welded to the outer wall of the fixed steel pipe. The eight steel bars are divided into two rows of four bars each.

[0008] Furthermore, the reinforcing bars are 8mm in diameter and 8cm in length threaded steel bars, with the four reinforcing bars at the bottom of the threaded joint fixed on the floor slab. The top of the floor slab is equipped with a roof filling layer, and the steel plate has a diameter of 80mm and a thickness of 10mm.

[0009] Furthermore, the vertical height from the top of the waterproof layer to the top of the roof filling layer shall not be less than 25cm, and the structural adhesive shall be silicone structural adhesive.

[0021] A fixing device for a precast fair-faced concrete solar roof foundation includes a receiving component 1 and a plug-in component 2. The receiving component 1 includes a movable steel pipe 3 and a threaded joint 4. The movable steel pipe 3 is a galvanized steel pipe with a diameter of 50mm and a height of 50cm. A threaded opening 13 is provided at a position 20cm below the bottom of the movable steel pipe 3.

[0022] Both the receiving component 1 and the plug-in component 2 are prefabricated in the factory, which allows for better control over the quality of the concrete, such as the quality of raw materials, mix proportions, and vibration processes. Then, the plug-in component 2 is placed in the formwork, and after pouring concrete, a prefabricated fair-faced concrete component 9 is formed. Prefabrication also improves construction efficiency. During roof construction, the prefabricated receiving component 1 and plug-in component 2 only need to be transported to the roof for installation, which is simple, time-saving, and labor-saving.

[0023] The threaded connector 4 has a diameter of 55mm and a height of 20cm. The outer wall of the threaded opening 13 is threaded to the inner wall of the threaded connector 4. By rotating and moving the steel pipe 3, the threaded opening 13 can be moved up and down along the threaded connector 4, thereby adjusting the height of the moving steel pipe 3 to adjust the overall height of the fixing device according to the actual construction needs.

[0024] Four reinforcing bars 5 are fixedly welded to the outer side of the bottom end of the threaded joint 4. The reinforcing bars 5 are threaded steel bars with a diameter of 8mm and a length of 8cm. The four reinforcing bars 5 at the bottom end of the threaded joint 4 are fixedly set on the floor slab 6.

A waterproof layer 12 is fixedly set on the movable steel pipe 3. The threaded joint 4 is fixed to the floor slab 6 by several reinforcing bars 5. The four reinforcing bars 5 can be pre-embedded in the floor slab 6. That is to say, the threaded joint 4 is pre-embedded in the floor slab 6, and then it is installed with the precast fair-faced concrete component 9 through socket joint.

[0025] The vertical height from the top of the waterproof layer 12 to the top of the roof filling layer 10 shall not be less than 25cm. That is to say, the waterproof layer 12 shall be extended onto the movable steel pipe 3, and the height of the waterproof layer 12 shall be at least 25cm higher than the roof filling layer 10, so as to better play the role of waterproofing.

[0026] The plug-in assembly 2 includes a fixed steel pipe 7, and several steel bars 5 are also fixedly installed on the outer wall of the fixed steel pipe 7.

A steel plate 8 is fixedly welded to the top of the fixed steel pipe 7. The steel plate 8 has a diameter of 80mm and a thickness of 10mm. The plug-in assembly 2 is placed in the template and cast to form a precast fair-faced concrete component 9.

[0027] Inside the factory, the plug-in component 2 is first placed in the casting template, and concrete is added into the template to form a precast fair-faced concrete component 9, which is the fair-faced concrete foundation for the roof solar panel. The eight steel bars 5 can make the plug-in component 2 more stable. After the steel plate 8 is installed, it contacts the top of the moving steel pipe 3, which can better form support.

[0028] The fixed steel pipe is a galvanized steel pipe. The diameter of the fixed steel pipe 7 is 80mm and the height is 35cm. The diameter of the fixed steel pipe 7 is larger than the diameter of the movable steel pipe 3, so that the fixed steel pipe 7 can be smoothly inserted into the top of the movable steel pipe 3, saving time and effort.

[0029] Finally, structural adhesive 11 is used to fill the gap between the bottom wall of the precast fair-faced concrete component 9 and the top of the roof filling layer 10. Structural adhesive 11 is silicone structural adhesive, which effectively solves the problem of cold joints easily forming during the pouring of beam-column joints.
