Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, specifically to a novel prefabricated steel structure greenhouse foundation. Background Technology

[0002] The emergence of solar greenhouses has solved the problem of winter vegetable production in northern regions. Currently, most solar greenhouses are based on brick-concrete structures, earthen wall structures, or rubble stone structures.

[0003] Among them, the foundation of the brick-concrete structure needs to be below the frost line, and depending on the geological structure, rubble, water-washed sand, reinforced concrete ring beams or pile concrete columns need to be used below the masonry foundation slab; construction waste is generated during the construction process, and the underground part of the wall must be below the frost line, construction is restricted by the external climate, and the project cost is high.

[0004] The foundation of the earthen wall structure requires the use of large excavators to excavate and pile up the earth for the back wall. The height of the back wall can reach 1.5-6 meters, and the thickness of the earthen wall base can generally reach 3-10 meters, with a top thickness of 1.2-3 meters. The amount of earth for the back wall is huge, and after piling, it needs to be wrapped to prevent rainwater erosion. It occupies a large area of ​​arable land, will damage the original topsoil layer during greenhouse construction, the earthen wall is easily eroded by rainwater, and once water enters the greenhouse, it will cause devastating damage to the wall structure.

[0005] Rubble masonry structures are only used in areas with abundant rubble resources. Because of the gaps between the rubble stones, cement mortar is needed for grouting and construction. The base thickness of a rubble masonry structure can reach 3-5 meters, and the top thickness 1-2 meters, requiring a huge amount of rubble material and labor. Rubble masonry structures are limited to areas with abundant rubble resources, are difficult to construct, and have high project costs.

[0006] In summary, existing greenhouse foundation types suffer from problems such as high construction difficulty, construction waste generation, and high project costs. Therefore, a new type of prefabricated steel structure greenhouse foundation is needed to solve the above-mentioned technical problems. Utility Model Content

[0010] Furthermore, the north side crossbeam, south side crossbeam, east side longitudinal beam, and west side longitudinal beam each include several beam segments, and adjacent beam segments are fixed together by ring beam connecting components and ring beam connecting bolts.

The first layer of water-retaining plate is connected and fixed to the frame, and the waterproof membrane is tightly attached to the first and second layers of water-retaining plates. The waterproof membrane extends upward along the foundation pit to the ground and then connects with the frame. The tops of the first and second layers of water-retaining plates are flush with the ground. The backfill soil in the foundation pit is compacted.

[0015] Furthermore, both the first and second water-blocking plates are extruded polystyrene boards.

[0031] Example 1

[0032] This embodiment is applicable to a structure with a single-layer frame on the north, south, east and west sides of the greenhouse, with one row of crossbeams 101 on the north side.

[0033] like Figure 1 and Figure 2As shown, a novel prefabricated steel structure greenhouse foundation includes a ring beam 1, ring beam connecting components 2, ring beam connecting bolts 3, anchor bolts 4, anchor bolt connecting bolts 5, ring beam transverse reinforcing bars 6, ring beam support plates 7, angle brackets 8, angle bracket connecting bolts 9, pre-embedded tie rods 10, and tie rod connecting bolts 11.

The east side longitudinal beams 103 and west side longitudinal beams 104 are fixed longitudinally to the east and west ends of the north side transverse beams 101 and south side transverse beams 102, respectively, forming a rectangular ring beam 1. Below the west longitudinal beam 104, several ring beam support plates 7 are spaced along the length direction. The ring beam support plates 7 are used to level the ring beam 1 as a whole and bear the downward load of the ground part of the ring beam 1. Several angle brackets 8 are fixed at intervals on the inner side of the north transverse beam 101, south transverse beam 102, east longitudinal beam 103, and west longitudinal beam 104 by angle bracket connecting bolts 9 to connect to the frame on the ground. Several anchor bolts 4 are fixed at intervals on the outer side of the north transverse beam 101, south transverse beam 102, east longitudinal beam 103, and west longitudinal beam 104 by anchor bolt connecting bolts 5. Pre-embedded tie rods 10 are fixed to all anchor bolts 4 of the north transverse beam 101 by tie rod connecting bolts 11. The pre-embedded tie rods 10 are used to connect the ground part of the pressure rope.

[0034] The north side crossbeam 101, south side crossbeam 102, east side longitudinal beam 103 and west side longitudinal beam 104 each include several beam segments, and adjacent beam segments are fixed together by ring beam connecting members 2 and ring beam connecting bolts 3.

[0035] The north side crossbeam 101, south side crossbeam 102, east side longitudinal beam 103, and west side longitudinal beam 104 are all angle steel made of hot-dip galvanized steel.

The two ends of the ring beam reinforcing rods 6 are connected to the two rows of north side crossbeams 101 respectively via reinforcing rod connecting bolts 601, further strengthening and fixing the connection between the two rows of north side crossbeams 101 through the ring beam reinforcing rods 6. The reinforcing rod connecting bolts 601 are made of hot-dip galvanized steel.

[0047] The installation method for the foundation of the novel prefabricated steel structure greenhouse in Example 2 is as follows: First, level the site, then mark the points and lay out lines along the axis of the ring beam, spreading lime. Excavate foundation pits 12 on the north, south, east, and west sides along the lime lines. Then, install the ring beam 1 along the axis of the ring beam 1 at the bottom of the foundation pit. During installation, adjacent beams of the north horizontal beam 101, south horizontal beam 102, east longitudinal beam 103, and west longitudinal beam 104 are fixed together by ring beam connecting components 2 and ring beam connecting bolts 3. Then, anchor rods 4 are nailed at intervals on the outer sides of the north horizontal beam 101, south horizontal beam 102, east longitudinal beam 103, and west longitudinal beam 104, and anchor rod connecting bolts 5 are installed to bolt and fix them to the ring beam 1. After the anchor rods 4 are installed, ring beam support plates 7 are evenly laid under the ring beam 1 (during construction, under the ring beam 1). (Reserve space for laying ring beam support plate 7), bolt the two rows of north side crossbeams 101 with ring beam reinforcing rods 6, install angle brackets 8 at intervals on the inner side of the north side crossbeam 101, south side crossbeam 102, east side longitudinal beam 103 and west side longitudinal beam 104 with angle bracket connecting bolts 9, and connect the angle brackets 8 to the frame on the ground with bolts. On all the anchor rods 4 of the north side crossbeam 101, pre-embedded tie rods 10 are fixed with tie rod connecting bolts 11 to connect the ground part of the pressure rope; then install the first layer of water retaining plate 131, waterproof membrane 14 and second layer of water retaining plate 132 in the foundation pit 12 of the south side crossbeam 102 in sequence, connect and fix the top of the waterproof membrane 14 to the frame, and finally backfill the soil 16 in all the foundation pits 12. After the soil 16 is half backfilled, use water to sink it and continue backfilling until all backfilling is completed.
