Description

Technical Field

[0001] The present invention relates to the technical field of greenhouse construction, and in particular to a quick-installation solar greenhouse using GFRP materials and a quick-installation method thereof. Background Art

[0002] Greenhouses, a vital component of modern agriculture, are widely used in northern China. Their primary function is to produce crops off-season. Traditional greenhouses, limited by materials and construction techniques, cannot be used in high-latitude regions. Furthermore, because agriculture has a long payback period, high-cost materials and technologies are not suitable for agricultural production, making large-scale application of many products in the greenhouse industry difficult.

[0003] Traditional greenhouses use concrete ground beams to fix the steel frame. Due to the high temperature and high humidity environment inside the greenhouse all year round, the steel frame is prone to corrosion. Secondly, the exterior wall insulation material of existing quick-install greenhouses is colored steel tiles, which are difficult to bend at the corner between the back slope and the back wall of the greenhouse, and the colored steel tiles are difficult to seal.

[0004] The disadvantages of the prior art are as follows.

[0005] (a) The traditional greenhouse steel frame is fixed in the concrete beam. In the high temperature and high humidity environment of the greenhouse, the steel frame corrodes too quickly, affecting its service life.

[0006] (b) Traditional solar greenhouse construction requires a large amount of steel, and the greenhouse frame itself is heavy and difficult to install and has a weak load-bearing capacity;

[0007] (c) The quick-install structure of the steel frame greenhouse cannot be completely separated from the welding work;

[0008] (d) Color steel tiles are difficult to bend. The joint between the back slope and the back wall of the greenhouse is not sealed tightly, which affects the thermal insulation effect. In addition, the iron sheet of the color steel tiles is not corrosion-resistant. Summary of the Invention

[0009] Based on the determination of the existing technology, the purpose of the present invention is to design a quick-install solar greenhouse using GFRP materials and a quick-install method thereof, using GFRP (glass fiber reinforced plastic) materials to replace traditional steel frames; FRP-XPS composite panels (FRP-glass reinforced plastic; XPS-extruded polystyrene foam panels) to replace traditional color steel tiles; GFRP materials cannot be welded, and a set of quick-install parts required for connecting the various components of the quick-install solar greenhouse using GFRP materials is designed.

[0010] The technical solution of the present invention is as follows: a quick-install solar greenhouse using GFRP material, wherein all skeleton parts are made of GFRP skeletons 1, the GFRP skeletons 1 are not bent, and the GFRP skeletons 1 are connected by quick-install parts.

[0011] The GFRP frame 1 is divided into greenhouse rear wall columns, greenhouse rear slope frame, greenhouse front roof frame, greenhouse side wall frame and greenhouse front bottom corner frame.

[0012] A quick installation method for a quick-install solar greenhouse using GFRP materials is as follows:

[0013] A ground beam trench is opened in the plot 20; a sand cushion layer 21 is filled at the bottom of the ground beam trench;

[0014] The GFRP ground beam 3 has holes on three sides, with circular holes on two opposite sides and a square hole on the top surface; the top surface where the square holes are located faces the sky and covers the entire ground beam groove of the plot 20;

[0015] The GFRP ground beam straight connector 10 is in a straight shape and has a circular hole on its side. When two GFRP ground beams 3 are directly connected, the GFRP ground beam straight connector 10 is respectively sleeved on the opposite ends of the two GFRP ground beams 3. The circular holes of the GFRP ground beam straight connector 10 are aligned with the circular holes of the GFRP ground beam 3. The GFRP pins 17 are inserted into the circular holes and fixed.

[0016] The GFRP ground beam right-angle connector 9 is in a straight line shape, with a circular hole on its side and a square hole on its top. When two GFRP ground beams 3 are connected at a right angle, one of the GFRP ground beams 3 has an opening on the side. One end of the GFRP ground beam right-angle connector 9 is inserted into the opening on the side of the GFRP ground beam 3, and the other end of the GFRP ground beam right-angle connector 9 is sleeved on one end of the other GFRP ground beam 3. After the circular holes of the GFRP ground beam right-angle connector 9 are aligned with the circular holes of the GFRP ground beam 3, a GFRP pin 17 is used to insert the circular holes and fix them.

[0017] The cross-section of the GFRP frame 1 is square and has two openings forming an "8" shape, with grooves on the side.

[0018] Insert one end of the GFRP frame 1 into the square hole of the GFRP ground beam right-angle connector 9; align the circular hole on the side of the GFRP frame 1 with the circular hole on the side of the GFRP ground beam right-angle connector 9, and insert the GFRP pin 17 to secure it. Connect them in sequence until the GFRP ground beam 3 is fixed.

[0019] The GFRP frame 1 has a circular hole at one end, which is inserted into the square opening of the GFRP ground beam 3. The GFRP pin 17 is inserted into the circular hole and fixed. All the greenhouse rear wall columns are plugged in sequence. The greenhouse rear slope frame is fixed to the greenhouse rear wall column using the rear slope connector 7. The greenhouse rear slope frame is fixed to the greenhouse front roof frame using the front roof connector 6. The greenhouse front roof frame is fixed to the greenhouse front bottom corner frame using the front bottom corner connector 5. The greenhouse front bottom corner frame is connected to the GFRP ground beam 3. One end of the greenhouse side wall frame is connected to the GFRP ground beam 3, and the other end is inserted into the batten.

[0020] At the same height as the GFRP frame 1, fix the GFRP round tube reinforcement 2 on the GFRP frame 1 through the GFRP reinforcement connector 4, and install the GFRP reinforcement connector 4 in sequence until the entire GFRP round tube reinforcement 2 is completely fixed;

[0021] Install GFRP wall panel clips 8 on the greenhouse rear wall columns and greenhouse side wall frames; clamp the composite panel bead c13 above the GFRP wall panel clips 8 at the same height, and insert the entire FRP+XPS composite panel 19 between the two composite panel bead c13; use GFRP pulled composite panel bead f16 to connect the FRP+XPS composite panel 19 at the corner of the greenhouse rear slope and the greenhouse rear wall; use GFRP pulled composite panels at the corner of the greenhouse rear slope and the greenhouse front roof. Bead d14 connects the FRP+XPS composite panel 19; GFRP-pulled composite panel bead b12 connects the FRP+XPS composite panel 19 at the corner of the greenhouse side wall and the greenhouse rear wall; composite panel bead a11 is used to secure the FRP+XPS composite panel 19 at the sealing point of the greenhouse front roof; GFRP-pulled composite panel bead e15 is used to secure the top of the greenhouse side wall and the greenhouse front roof frame; polyurethane foam 18 is sprayed on the greenhouse interior rear wall, rear slope, and side walls;

[0022] Finally, fill the ground beam trench.

[0023] The GFRP tie rod connector 4 is a C-shaped structure as a whole, with four legs, and the ends of the legs are bent. The gap formed by the four legs embraces the GFRP round tube tie rod 2, and the bends at the ends of the legs are stuck in the side grooves of the GFRP skeleton 1 to complete the fixation.

[0024] The cross-sectional structure of the composite panel strip a11 is an H-shaped structure as a whole, including two horizontal sides and one vertical side; the horizontal sides are divided into long horizontal sides and short horizontal sides; a flat C-shaped opening is provided on the inner side of the long horizontal side, and the size and depth of the C-shaped opening are consistent with the original film clamping groove, which is used to fix the greenhouse film retaining spring; the vertical side is close to one end of the short horizontal side, and two square and circular guide grooves are respectively provided for installing and fixing rainproof strips; the sealing part of the FRP+XPS composite panel 19 of the front roof of the greenhouse is directly inserted into the composite panel strip a11.

[0025] The composite panel bead c13 is an H-shaped structure, and a groove having the same size as the raised sheet of the wall panel clip 8 is added to one vertical side thereof, and the raised sheet and the groove are fastened up and down.

[0026] The wall panel clip 8 is a C-shaped structure as a whole, with a raised thin plate at the bottom of the structure. The thickness of the raised thin plate is consistent with the width of the groove of the composite panel layer c13.

[0027] The main body of the composite panel strip e15 is an E-shaped structure, with two notches on its vertical side. The size of the first notch is exactly the same as the thickness of the FRP+XPS composite panel 19, and the size of the second notch is adapted to the GFRP skeleton 1; there are two flat C-shaped openings on the opposite side of the second notch, and the size and depth of the C-shaped openings are consistent with the film clamping groove, which is used to fix the greenhouse film retaining spring.

[0029] Beneficial effects of the present invention:
