CN2409257Y - Butt jointing structure of plastic-steel plate for partition - Google Patents

Abstract

The utility model discloses a butt joint structure of a plastic-steel board for separating rooms, which is characterized in that butt joint ends at both sides of a plate (2) form wedge contacts (26) (25) with left and right sides and the wedge contacts (26) (25) are formed by two groups of symmetrical convex tenons (22) (21) and concave grooves (24) (23) which are mutually butted. The structure has the advantages of multilayer locking operation, strong combining ability, a plurality of folding angles and good blocking effect on gas and water.

Description

Compartment is constructed with the butt joint of plastic-steel plate

The utility model relates to a kind of butt joint structure that is used for the plastic-steel plate of compartment or dustfree environment demand.

At present, the plastic-steel plate is because its quality has good characteristic, so in lightweight compartment or dustfree environment extensive use now, the main body of plastic-steel sheet material is the plate that one li portion is formed with dead slot, its cross section is a rectangle; And when constituting the metope of compartment, be between two plates (11), (12), as shown in Figure 1, to being separated with the indirect material (13) of a H shape, owing to the existence of this indirect material (13), after metope forms, joint can be given prominence to a raised line (14), influences the planarization of metope; In addition, also has counter structure as shown in Figure 2, establish concavo-convex wedge interface (15) at the interface of two plates (11), (12), after two plates (11), (12) butt joint, involutory surface only forms to engage at central portion mainly does the force, if another plate (12) is bestowed external force F, the central point of convex is difficult to the strength with a bit, resist external external force F, two docking plates (11), (12) are broken away from.

The purpose of this utility model provides the butt joint structure of the strong compartment of a kind of combining ability with the plastic-steel plate.

For reaching above-mentioned purpose, the utility model by the following technical solutions:

The utility model is two side butt ends at plastic-steel sheet material, the wedge joint of two sides point about being formed with, and this wedge joint point be by the tenon of two groups of symmetries and groove mutually to forming, this butt joint structure can obviously increase its combining ability, and air capable of blocking or water flow through from its butt joint.

The utility model will be further described below in conjunction with the embodiment accompanying drawing:

Fig. 1 is one of the involutory mode of a common plastic-steel plate schematic diagram.

Fig. 2 is two schematic diagrames of the involutory mode of common plastic-steel plate.

Fig. 3 is the utility model embodiment schematic diagram.

(11), (12) are that plate, (13) are that the right tenon, (22) for left side tenon, (23) for the right groove, (24) for left side groove, (25), (26) for wedge joint point, (27), (28) be screw, (3) for slot, (20) be limit face for wedge interface, (2) for sheet material, (21) for raised line, (15) for indirect material, (14).

As shown in Figure 3, the utility model is the butt joint side at sheet material (2), mode with male and female, be provided with adjacent limit, left and right sides tenon (22), (21) and relative limit, left and right sides groove (24), (23), utilize the right tenon (21) to wedge relative set limit, the left and right sides groove (24) of opposite sheet material respectively with left side tenon (22), (23) after, form two and make power wedge joint point (25), (26), and respectively by screw (28), (27) attack lock from two side faces, two-screw (27), (28) can obtain interlocking layer more than at least five layers respectively, this interlocking layer is perpendicular to screw (27) by tenon and groove, (28) limit face forms, utilize the mode of this multilayer locking, except increase is spirally connected the effect, more be adjacent to relatively because of polygon, and significantly increase the frictional force at interface, thereby obviously increase its combined friction power, auxiliary combination structural strength; Again since about the existence of two groups of tenons and groove, make this wedging face form the form of polygon shape vertical butt joint, so air or water or other fluid be difficult to wear the slot (3) of walking around this wedge joint face, to reach the good barrier property of convection cell; Again because two groups tenon and groove about being provided with, utilize the wedge joint of two tenons, as shown in Figure 3, under the principle of 2 being aligneds, be subjected to external force F at side plate material (2) and do the time spent, wedge joint point (26) that then can on the left side tenon (22) produces extruding force, and wedge joint point (25) produces and to make the removal force of this tenon (21) between relative with groove (23) on the right, owing to add that opposite frictional force and wedge mouth that several limit faces (20) form to each other are the mechanical enhancer power of polygon shape turnover, and can be directly in this wedge oral area position, eliminate the influence of external force F, reach the effective combination between the sheet material this wedge joint power.

Claims (1)

1, a kind of compartment is constructed with the butt joint of plastic-steel plate, it is characterized in that: at two butt joint sides of sheet material (2), be provided with adjacent limit, left and right sides tenon (22), (21) and relative limit, left and right sides groove (24), (23), two sheet materials (2) utilize the tenon and the groove butt joint of two butt joint sides, form limit, left and right sides wedge joint point (26), (25).
