Abstract
The utility model relates to a sandwich connecting element capable of being stably connected with a horizontal floor and a vertical wallboard. The sandwich connecting element comprises a connecting bottom plate, a herringbone sandwich panel connected in a herringbone shape, two panel connecting pieces with small holes in the middles, a pouring core and a T-type reinforcing block. The wing edge of the T-type reinforcing block is adhered to the middle of the connecting bottom plate, the herringbone sandwich panel is connected with the bottom plate through glue and screws, the two panel connecting pieces with the small holes are located on the two sides of the herringbone sandwich panel respectively, and the pouring core is placed in the space composed by the panel connecting pieces, the herringbone sandwich panel and the connecting bottom plate. The sandwich connecting element can strengthen bearing force of a structure, enables the structure to have the advantages of being fatigue-resistant, shock-absorbing and sound-proof, additionally, can effectively reduce stress concentration phenomena at a joint, improves efficiency of the structure, and greatly reduces the weight of the structure on the basis that structure performance is not reduced due to adoption of the pouring core made of polyurethane elastomer.
Description
Technical field
What the present invention relates to is a kind ofly can realize the sandwich link that be connected firm with horizontal floor and vertical wallboard.
Background technique
Along with the development of materials science research and deeply, the fast development in every field of new material and new technology, the exploitation of material behavior and high performance material and scientific research will become the from now on focal issue in very long one period.In numerous new materials, Sandwich Plates take the hard polyurethane ester elastomer as fuse is a kind of relatively structural type of novel practical, it is not only superior than single isotropic material aspect intensity, vibration damping, noise reduction and the mechanical characteristic such as uprising, can also play light-weighted effect.Fast, firmly be this sandwich structure to be applied to the most important thing of engineering field, so must find a kind of suitable, durable connected system, guarantee the long-term safety of structure.And this link can make sandwich structure and firm being connected in other positions, and it is simple to have the system architecture form, and is cheap practical, the advantages such as strong adaptability.
Summary of the invention
The object of the present invention is to provide a kind of sandwich linkage structure in heavy mechanical equipment, building and shipbuilding industry.
The object of the present invention is achieved like this:
The sandwich link, comprise connecting bottom board, one the be man type chevron shaped sandwich board that connects, the two foraminate desk connectors of Intermediate Gray, cast core and T-shaped enhancing pieces, the wing rafter of T-shaped enhancing piece is adhesive in the neutral position of connecting bottom board, link together by glue and screw between chevron shaped sandwich board and the base plate, two with foraminate desk connector be positioned at chevron shaped sandwich board both sides, build core and be filled in desk connector, chevron shaped sandwich board, the gluing space that connects and composes of connecting bottom board.
Respectively there is an aperture to be used for vacuum pouring cast core in the middle of the desk connector.
Connecting bottom board, desk connector and T-shaped enhancing piece are made by metal, metal alloy or composite material.
The cast core is to be mixed with a kind of hard polyurethane ester elastomer that forms by polyester and isocyanates.
Chevron shaped sandwich board can adopt polyurethane elastomer sandwich board, honeycomb sandwich board or Composite Sandwich Plates.
Beneficial effect of the present invention is:
At first, two panel support of sandwich board form larger bending resistance moment as the primary load bearing member between two panels, make structure have very high flexural rigidity, and can select different sandwich boards according to actual requirement; Secondly, cast core between sandwich board and the T-shaped enhancing piece is the good hard polyurethane ester elastomer of a kind of energy-absorbing effect, can strengthen the bearing capacity of structure, makes structure have the advantage of endurance, damping, sound insulation, also can effectively alleviate simultaneously joint stress and concentrate, improve structure efficiency; At last, the cast core of employing polyurethane elastomer can alleviate the quality of structure greatly when not reducing structural behaviour.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is structural section figure of the present invention.
Specific embodiments
For example the present invention is done more detailed description below in conjunction with accompanying drawing:
Comprise connecting bottom board, (two panels on sandwich board top accompany fuse to a chevron shaped sandwich board, the bottom only has the panel of outwards bypassing), two be with foraminate desk connector, cast fuse (a kind of hard polyurethane ester elastomer, vacuum pouring forms) and one of T-shaped enhancing, the wing rafter of T-shaped enhancing piece and connecting bottom board glued joint, mixed with screw by glue between chevron shaped body sandwich board and the base plate and be connected, two are positioned at the both sides, front and back of fuse, glued joint with chevron shaped sandwich board, base plate link and form with foraminate desk connector, and fuse forms for cast.
The present invention can also comprise:
Described polyurethane elastomer is to be mixed at a certain temperature with isocyanates by polyester (perhaps polyethers), vacuumizes cast and forms, and according to different needs, its performance can be selected prescription and change.
Fig. 1 is sandwich linkage structure overall diagram, and Fig. 2 is sandwich linkage structure sectional view.The present invention mainly comprises base plate 4 and T-shaped enhancing piece 5, and its major character is: the wing rafter of T-shaped enhancing piece 5 and connecting bottom board 4 glued joint.The present invention comprises that also 1, two of a chevron shaped sandwich board is with foraminate desk connector 3, and chevron shaped sandwich board 1 is mixed with screw by glue with base plate 4 and is connected, and two are with between foraminate desk connector 3 and chevron shaped sandwich board 1, the base plate 4 is that splicing forms.The present invention also comprises fuse 6 simultaneously, and it is to utilize the aperture cast of link 3 to form.
Working process of the present invention is: T-shaped enhancing piece 5 and base plate link 4 is bonding, bonding process is: will carry out surface treatment to the adherend surface first, adopt the removing surface method to remove by the oxide of maxxaedium, the foreign matter crud layers such as greasy dirt, moisture film and the gas of absorption, the clean surface, make the surface obtain suitable roughness, then Bond J39 evenly is coated in by on the maxxaedium, require the gluing uniformity, avoid air to sneak into, reach without holiday, starved not, without bubble, do not pile up, bondline thickness is controlled at 0.08～0.15mm, pushes at last and treats that it solidifies complete getting final product behind the certain hour, and following adhering method is identical therewith.Then integral body is mixed with screw by glue with chevron shaped sandwich board 1 and be connected, then be with foraminate desk connector 3 and chevron shaped sandwich board 1, base plate 4 to glued joint with two, form a cavity structure, insert in the aperture of link 3 with two sections conduits at last, the polyurethane elastomer vacuum pouring that mixing reaction is good is entered, after it solidifies, namely finish.
