technical field

The utility model relates to the technical field of shelters, in particular to a connecting edge for composite material shelters.

Background technique

The shelter is a structure similar to a container. It is organically combined with various strong materials to form a convenient and movable whole. As an independent box, the shelter must be able to adapt to various methods of loading, unloading and transportation , can provide suitable working environment and safety protection for staff and equipment.

Due to the particularity of the use of the shelter, in the design and production, its mechanical properties, airtightness and thermal insulation must be considered. The large-slab shelter is one of the existing structural forms of the shelter. The large-slab shelter is made of large It is an integral structure composed of plates, corner pieces, bent angles, etc. connected by bolts, rivets, and sealing plates. Since the mechanical connection performance of the composite material skin is not as good as that of the traditional aluminum alloy skin, when the existing edge structure is used for connection, it is necessary to prefabricate the metal skeleton inside the composite material slab, and the composite material slab with the metal skeleton is not only The weight is heavy, the matching of materials is not good, and it also brings great inconvenience to the production. Therefore, the existing edges are not suitable for the connection of large composite material plates. Based on this, a new type of composite material shelter is designed. It is still necessary to connect the edges.

Utility model content

Aiming at the deficiencies in the prior art, the purpose of this utility model is to provide a connecting edge for a composite material shelter, which has a simple structure, reasonable design, high rigidity, high connection strength, easy assembly, and improves the overall quality of the large plate shelter. The structure is reliable and airtight, has strong practicability, and is easy to popularize and use.

In order to achieve the above object, the utility model is achieved through the following technical solutions: a connecting edge for a shelter made of composite material, including a body, a square hole, a first U-shaped groove and a second U-shaped groove, A square hole, a first U-shaped groove, and a second U-shaped groove are provided. The two sides of the square hole are provided with a first U-shaped groove and a second U-shaped groove perpendicular to each other. The body passes through the first U-shaped groove. The groove and the second U-shaped groove are connected with the big board of the shelter, and the connection between the edge and the big board of the shelter is fully glued.

Preferably, the first U-shaped groove is glued to the left side plate, and the left side plate is inserted longitudinally into the first U-shaped groove; the groove interface of the first U-shaped groove is connected to the left side plate Structural adhesive is applied to the edges of both sides of the U-shaped groove, and the U-shaped groove socket of the first U-shaped groove is glued to the left side plate.

As a preference, the second U-shaped groove is glued to the bottom plate, and the bottom plate is inserted into the second U-shaped groove transversely; the groove interface of the second U-shaped groove and both sides of the bottom plate are coated with Structural adhesive, the U-shaped groove socket of the second U-shaped groove is glued to the bottom plate.

The beneficial effects of the utility model: (1) The structure is simple, easy to assemble, and the overall reliability and airtightness of the large-slab shelter are greatly improved.

(2) The edge itself has high rigidity. As the load-bearing skeleton of the composite material shelter, it effectively transmits the load between the corner parts of the shelter and the skin, and solves the defect of insufficient rigidity of the skeleton connection structure.

(3) There is no need for riveting and fixing. Under the condition of only using structural adhesive, one edge can connect two adjacent side panels of the shelter together. The connection strength between the edge and the large panel of the shelter is high and the airtight performance it is good.

(4) The material of the edge structure is not limited, it can be made of metal material or composite material, and the most suitable material and processing technology can be selected according to specific requirements.

detailed description

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

Referring to Figures 1-3, this specific embodiment adopts the following technical solutions: a connecting edge for a shelter made of composite materials, including a body 1, a square hole 2, a first U-shaped groove 3 and a second U-shaped groove 4, The body 1 is provided with a square hole 2, a first U-shaped groove 3, and a second U-shaped groove 4, and the two sides of the square hole 2 are provided with a first U-shaped groove 3 and a second U-shaped groove perpendicular to each other. 4. The main body 1 is connected with the large panel of the shelter through the first U-shaped groove 3 and the second U-shaped groove 4, and the top plate, the bottom plate of the large plate of the shelter and each side plate are connected to each other through the edges.

It is worth noting that the first U-shaped groove 3 is glued to the left side plate 5, and the left side plate 5 is inserted longitudinally into the first U-shaped groove 3; The groove interface and both sides of the left side plate 5 are coated with structural adhesive, and the U-shaped groove socket of the first U-shaped groove 3 is glued to the left side plate 5 .

It is worth noting that the second U-shaped groove 4 is glued to the bottom plate 6, and the bottom plate 6 is inserted laterally into the second U-shaped groove 4; the groove interface of the second U-shaped groove 4 is connected to the Both sides of the bottom plate 6 are coated with structural adhesive, and the U-shaped groove socket of the second U-shaped groove 4 is glued to the bottom plate 6 .

In addition, the edge is made of metal material or composite material, and the material of the edge is not limited. The edge can be made of carbon fiber or glass fiber as a reinforcing material, epoxy resin as a matrix material, and is prepared by a pultrusion process. This kind of composite material has high edge strength, extremely small thermal stress, and strong corrosion resistance; edge processing and molding processes are not limited.

This specific embodiment consists of a square hole and a pair of U-shaped grooves perpendicular to each other. The function of the U-shaped grooves is to cooperate with the large board of the shelter. The inside of the U-shaped groove and the edge of the large slab of the shelter are coated with structural adhesive, and the structural adhesive also plays a role of sealing while connecting; the U-shaped groove socket on the edge and the sandwich structure The composite material shelter slabs are glued together, which can further strengthen the sandwich structure of the shelter slabs.

Taking the connection structure between the edge and the left side plate 5 and the bottom plate 6 as an example (Fig. 3), apply structural adhesive to the groove interface between the edges on both sides of the left side plate 5 and the first U-shaped groove 3 of the edge, and place the left side The plate 5 is inserted longitudinally into the first U-shaped groove 3, and the structural adhesive is applied to the groove interface between the edge of the bottom plate 6 and the edge of the second U-shaped groove 4, and the bottom plate 6 is inserted horizontally into the second U-shaped groove 4; finally The structural adhesive is cured at room temperature to realize the high-strength connection between the left side panel 5 and the bottom panel 6 . The area where the square hole 2 is located is the connection and matching area between the corner fittings and the edges at the eight vertices of the shelter. This seam connection method can greatly improve the reliability and airtightness of the overall connection of the composite shelter.
