[0050] Production and construction process:

[0051] The construction process of the assembled slope roof structure of the present invention generally includes the following steps: production of lightweight insulation blocks → production of assembled slope roof panels → production of prefabricated groove beams → installation of prefabricated groove beams and columns → hoisting of assembled slope roof panels → construction of waterproof layer; the specific process is as follows:

[0052] Step 1, process and manufacture lightweight thermal insulation blocks according to the designed size; preferably, process and manufacture according to the size of 450mm×450mm×80mm; the test mold material uses 5mm thick steel plate, each steel plate of the test mold can be freely disassembled and assembled, and no gap is left after assembly; the raw materials of the lightweight thermal insulation blocks are recycled brick aggregate, polystyrene particles, cement and sand, and the lightweight thermal insulation concrete is prepared according to the following mix ratio design, and the mix ratio is: cement: water: sand: recycled brick aggregate: polystyrene particles = 1:0.5:1.2:1.8:0.2; then, pour the lightweight thermal insulation concrete into the steel mold, remove the mold after 2 days and move it to the concrete curing room for standard curing to 28 days.

[0053] Step 2: Make the prefabricated slope roof panel template according to the size and assemble it, embed the PVC sleeve in the reserved drainage hole position, embed the PVC sleeve in the reserved hole position of the tension bolt of the L-shaped beam, and embed the bolt in the connection position of the L-shaped connecting plate; tie the steel bars of the reinforced concrete base plate and rib grid, place lightweight insulation blocks at the corresponding position, pour concrete and vibrate it to make it dense.

[0054] Step 3: Make the groove beam template according to the size and assemble it, embed the PVC sleeve in the reserved hole for the tension bolt connected to the L-shaped beam, embed the bolts in the connection position of the rectangular connecting plate, pour the concrete and vibrate it to make it dense.

[0055] Step 4. Before constructing the columns, embedded bolts should be placed according to the connection positions. Before hoisting the prefabricated grooved beams, 2 cm of cement mortar should be applied to the top of the columns to form a cement mortar layer. Use measuring equipment to accurately determine the elevation and axis position of the grooved beams. Then hoist the prefabricated grooved beams to the top of the columns and accurately position them. Use rectangular connecting plates and embedded bolts to connect the columns and prefabricated grooved beams together to ensure a reliable connection.

[0056] Step 5. Connect one end of the downhill roof panel to the second column through an L-shaped connecting plate, insert the L-shaped beam at the other end into the prefabricated groove beam and connect it through tension bolts, and fill the gap between the L-shaped beam and the prefabricated groove beam with cement mortar; insert both ends of the mid-slope roof panel and the uphill roof panel into the prefabricated groove beam respectively and fill the gap between them with cement mortar.

[0057] Step 6. After all the prefabricated sloping roof panels are assembled, fill the gaps of the prefabricated sloping roof panels with cement mortar; then lay the waterproofing membrane. The waterproofing membrane should be laid from the lowest point. First, put the waterproofing membrane in the right position, leaving 8cm joints on the long side and 10cm joints on the short side; then, light the blowtorch and heat it evenly at the bottom surface of the waterproofing membrane and the surface of the base layer; the blowtorch nozzle should be about 30cm away from the surface of the membrane; after the surface of the waterproofing membrane is melted, roll the waterproofing membrane forward and compact it flat. It is best to press out the melted asphalt at the joint part. Do not roll in air and foreign objects when rolling, and prevent deflection, bulging and wrinkling. Finally, use a blowtorch and a press to seal the joints evenly and carefully to prevent warping.

[0058] In the present invention, the structures of the uphill roof panel and the medium-slope roof panel are the same, and both the uphill roof panel and the medium-slope roof panel adopt assembled slope roof panels without drainage grooves; and the difference between the downhill roof panel and the uphill roof panel or the medium-slope roof panel is that a drainage groove is arranged at the lower end of the assembled slope roof panel without drainage grooves to form a slope roof panel structure with drainage grooves.

[0059] The assembled sloping roof structure described in the present invention comprises an assembled sloping roof panel, an L-shaped beam, a prefabricated groove beam and a column; wherein the assembled sloping roof panel comprises a reinforced concrete rib, a building block and a reinforced concrete bottom plate; the assembled sloping roof panel has two forms, one with a drainage groove and one without a drainage groove, the assembled sloping roof panel with a drainage groove is used for the eaves position of the sloping roof, and the one without a drainage groove is used for other positions; the building blocks adopt lightweight insulation building blocks, and the lightweight insulation building blocks are prepared according to a preset proportion by recycled brick aggregate, polystyrene particles, cement, sand and water; wherein the recycled brick aggregate has a small density and a large porosity, and the recycled brick aggregate has both certain insulation performance and certain strength; the recycled brick aggregate plays the role of insulation and skeleton in the building block, the cement mortar plays the role of bonding, and the polystyrene particles play the role of insulation, thereby forming a lightweight insulation building block with both certain strength and good insulation effect.

[0060] In the present invention, the assembled sloping roof panel and the prefabricated groove beam are mainly connected by tension bolts, and reserved holes for tension bolts are reserved at corresponding positions when the L-shaped beam and the prefabricated groove beam are used; the gaps between the L-shaped beam and the prefabricated groove beam and between the sloping roof panels are filled with cement mortar grouting material; the assembled sloping roof panel with a drainage groove at the eaves position is connected to the second column by an L-shaped connecting plate, and bolts should be embedded in corresponding positions when the assembled sloping roof panel and the column are manufactured; the prefabricated groove beam and the column are mainly connected by a rectangular connecting plate, and bolts should be embedded in corresponding positions when the L-shaped beam and the column are manufactured; and a waterproof layer is laid after the assembled sloping roof panel is assembled.

[0061] Compared with the traditional sloping roof construction method, the prefabricated sloping roof of the present invention adopts the construction mode of industrialized production, professional distribution and assembly construction. The construction site mainly relies on professional light machinery, uses less labor, has a high degree of automation, fast construction speed, high production efficiency, and is energy-saving and environmentally friendly. The interior of the prefabricated sloping roof panel is filled with lightweight insulation blocks, and the lightweight insulation material uses recycled brick aggregate polystyrene particle concrete, which not only reduces its own weight, but also realizes the recycling of construction waste.

[0062] The above embodiment is only one of the implementation methods that can realize the technical solution of the present invention. The scope of protection claimed by the present invention is not limited only to this embodiment, but also includes changes, replacements and other implementation methods that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention.
