Abstract
The utility model provides a composite beam for manufacturing a greenhouse framework. The composite beam is composed of a pair of C-shaped steel beams which are open oppositely, and reinforcing ribs connected between the C-shaped steel beams, wherein the reinforcing ribs are alternately mounted between the C-shaped steel beams in a splay combination manner, and connected with the C-shaped steel beams through expansion bolts. The composite beam is characterized in that no middle supporting pillar is needed inside the composite beam so that the utilization amount of the steel materials is reduced, the middle reinforcing rib structure greatly improves the strength of the greenhouse framework and prolongs the service life of the greenhouse framework, only composite beams can be used or the composite beam can be combined with a single C-shaped steel beam to be used alternatively, the transmission of light of the greenhouse is improved, and vegetables can be suspended vertically or transversely; even though no external cable-stayed support needs to be added as the reinforcing rib, high strength can be obtained, and therefore, the composite beam is beautiful and practical, and also social resources are saved; the use of the combination of the C-shaped steel beams does not cause damage to the thin film of the greenhouse; connection is realized by using the expansion bolts or embedded parts, and a middle bolt without welding, and consequently, the composite beam is convenient to mount and demount.
Description
Technical field
The utility model relates to a kind of composite beam for the manufacture of Keelof green house, belongs to agricultural greenhouse technical field.
Background technology
China's facilities horticulture engineering develops rapidly in recent years, in order to reduce agricultural chemicals and to increase output, the China that is planted in of greenhouse vegetable develops rapidly, various agricultural greenhouse scales constantly expand, as stock---the big-canopy framework of building booth, but can not meet the demand of booth develop rapidly always.Tradition booth adopts the materials such as bamboo and wood, steel, cement to build more.Bamboo Muyi is rotted, and only have 2 years application life, and the booth internal stent that bamboo wood is built is too many, and not only impact is planted, and also greatly reduces the utilization rate in space; Too high by the greenhouse bracket cost of coating steel pipe welding, easily get rusty again, through solar radiation distribute heat, easily canopy film is burnt rotten; The booth of building with cement is extremely heavy, not quick detachable, is more unfavorable for popularizing of canopy chamber; Adopt pipe, its bearing capacity is bad, adopts C shaped steel to add after composite beam, greatly reduce the use amount of steel, but its independent working strength is inadequate, must be used in conjunction with other supplemental support, generally adopt C type beam as main framing, its outside is by oblique pull support and connection body of wall, greenhouse body interior adds intermediate supports pillar, and three is used in combination to increase Keelof green house rigidity, and such combination had both increased steel use amount, reduce again greenhouse principal space, and be unfavorable for vegetables handling.
Utility model content
For the problems referred to above, the utility model provides a kind of composite beam for the manufacture of Keelof green house, and its object is: improve greenhouse application life, increase the intensity of greenhouse main body in the time of saving steel use amount, realize the flexible handling of vegetables.
Technical solution of the present utility model:
A kind of composite beam for the manufacture of Keelof green house, it is characterized in that: described composite beam is comprised of with the reinforcing rib being connected in therebetween the opposing C section steel beam of pair of openings, described reinforcing rib is alternately installed between C section steel beam by " eight " font combination, between described reinforcing rib and C section steel beam, by expansion bolt, is connected.
Described composite beam can be installed separately side by side, also can use with single C section steel beam combined and alternatively, between composite beam is adjacent with single C section steel beam, by vertical girder steel, fixes.
Described vertical girder steel cross section is C type.
Described C section steel beam opening both sides are arc internal fastening type structure.
The beneficial effects of the utility model:
The utility model inside is without intermediate supports pillar, reduced the use amount of steel, middle reinforcing rib structure, intensity and the application life of Keelof green house have greatly been increased, can adopt pure composite beam or use with single C section steel beam combined and alternatively, increase the light transmission in greenhouse, can also can laterally hang dish for vertical lifting dish; Do not need additional oblique pull to support and can obtain high strength as reinforcing rib, both artistic and practical, saved social resources; Not being used in combination of C shaped steel can cause damage to greenhouse film; Adopt expansion bolt or built-in fitting to connect, middle Bolt Connection, does not need welding, easy installation and removal.
Accompanying drawing explanation
Fig. 1: the utility model structural principle schematic diagram.
Fig. 2: the utility model structural principle schematic diagram.
Fig. 3: the utility model A-A cross-sectional view.
Wherein: the vertical girder steel of 1 C section steel beam 2 C section steel beam 3 reinforcing rib 4 expansion bolt 5.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
A kind of composite beam for the manufacture of Keelof green house as shown in Figures 1 to 3, described composite beam is comprised of with the reinforcing rib 3 being connected in therebetween the opposing C section steel beam of pair of openings, between reinforcing rib 3 and C section steel beam, by expansion bolt 4, be connected, reinforcing rib 3 is alternately installed between C section steel beam by " eight " font combination, described composite beam can be installed separately side by side, also can use with single C section steel beam combined and alternatively, it is fixing by vertical girder steel 5 between composite beam is adjacent with single C section steel beam, described vertical girder steel 5 cross sections are C type, described C section steel beam 1, C section steel beam 2 opening both sides are arc internal fastening type structure.
Embodiment:
Reinforcing rib is alternately installed between C section steel beam by " eight " font combination each other, increased the pressure-bearing type of C section steel beam, strength deficiency when can make up the use of single C section steel beam, the composite beam forming can be installed separately side by side, also can use with single C section steel beam combined and alternatively, by vertical girder steel, fix for adjacent.Not being used in combination of C shaped steel can cause damage to greenhouse film; Adopt expansion bolt or built-in fitting to connect, middle Bolt Connection, does not need welding, easy installation and removal, the application life of greatly having improved greenhouse.By this combination, can increase in the situation of greenhouse body span, the use amount of steel, without intermediate supports pillar, has been reduced in inside, has increased the light transmission in greenhouse, can also can laterally hang dish for vertical lifting dish; Do not need additional oblique pull to support and can obtain high strength as reinforcing rib, both artistic and practical, saved social resources.
To sum up, the utility model accomplishes the end in view.
