Abstract
The invention relates to a sandwich connector. By the sandwich connector, a horizontal floor can be stably connected with a vertical wallboard. The sandwich connector comprises a connecting bottom plate, a herringbone sandwich board, two panel connectors with middle small holes, a poured core and a T-shaped reinforcing block. Components of the herringbone sandwich board are connected with each other in a herringbone manner, wing rafters of the T-shaped reinforcing block are adhered in the middle of the connecting bottom plate, the herringbone sandwich board is connected with the bottom plate by adhesive and screws, the two panel connectors with the small holes are positioned on two sides of the herringbone sandwich board, the poured core is filled in space, and the panel connectors, the herringbone sandwich board and the connecting bottom plate are connected with one another by means of adhesion to form the space. The sandwich connector has the advantages that the bearing capacity of a structure can be improved, the structure is fatigue-resistant, shock-absorbing and sound-insulation, stress concentration at a joint can be effectively relieved, and the efficiency of the structure is improved; and the weight of the structure can be greatly reduced while the performance of the structure is not deteriorated owing to the poured core which is a 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 vertical wallboard with horizontal floor.
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 focal issue in very long one period from now on.In numerous new materials, Sandwich Plates taking 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.Be fast, firmly the most important thing that this sandwich structure is applied to engineering field, so must find a kind of suitable, durable connected system, ensure 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 system architecture form, cheaply 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:
Sandwich link, comprise connecting bottom board, one the be man type chevron shaped sandwich board connecting, 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, between chevron shaped sandwich board and base plate, link together by glue and screw, 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 connecting and composing of connecting bottom board.
In the middle of desk connector, respectively there is an aperture to pour into a mould core for vacuum pouring.
Connecting bottom board, desk connector and T-shaped enhancing piece are made up of metal, metal alloy or composite material.
Cast core is to be mixed with by polyester and isocyanates a kind of hard polyurethane ester elastomer forming.
Chevron shaped sandwich board can adopt polyurethane elastomer sandwich board, honeycomb sandwich board or Composite Sandwich Plates.
Beneficial effect of the present invention is:
First, two panel support of sandwich board, as primary load bearing member, form larger bending resistance moment 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 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 advantages of endurance, damping, sound insulation, also can effectively alleviate joint stress simultaneously and concentrate, improve structure efficiency; Finally, adopt the cast core of polyurethane elastomer can in not reducing structural behaviour, greatly alleviate the quality of structure.
Brief description of the 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 described in more detail below in conjunction with accompanying drawing:
Comprise base plate, (two panels on sandwich board top accompany fuse to a chevron shaped sandwich board, 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 base plate glued joint, between chevron shaped body sandwich board and base plate, mix and be connected with screw by glue, two are positioned at the both sides, front and back of fuse, glued joint and form with chevron shaped sandwich board, base plate with foraminate desk connector, and fuse forms for pouring into a mould.
The present invention can also comprise:
Described polyurethane elastomer is to be mixed at a certain temperature with isocyanates by polyester (or polyethers), vacuumizes cast and forms, and according to different needs, its performance can be selected formula 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: wing rafter and the base plate 4 of T-shaped enhancing piece 5 glued joint.The present invention also comprises that 1, two of a chevron shaped sandwich board is with foraminate desk connector 3, and chevron shaped sandwich board 1 is mixed and is connected with screw by glue with base plate 4, and two are with between foraminate desk connector 3 and chevron shaped sandwich board 1, 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: by bonding to T-shaped enhancing piece 5 and base plate 4, bonding process is: first will carry out surface treatment to adherend surface, adopt 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, clean surface, make surface obtain suitable roughness, then Bond J39 is evenly coated in by maxxaedium, require gluing uniformity, avoid air to sneak into, reach without holiday, not starved, without bubble, do not pile up, bondline thickness is controlled at 0.08～0.15mm, after finally pushing certain hour, treat that it is curing complete, following adhering method is identical therewith.Then entirety is mixed and is connected with screw by glue with chevron shaped sandwich board 1, then be with foraminate desk connector 3 to glued joint with chevron shaped sandwich board 1, base plate 4 by two, form a cavity structure, finally insert in the aperture of link 3 with two sections of conduits, the polyurethane elastomer vacuum pouring that mixing reaction is good is entered, after it solidifies, complete.
