Description

Fence board

Technical Field

The utility model relates to a fence board, and belongs to the technical field of wood-plastic materials.

Background

The fence board is suitable for a plurality of occasions, such as courtyards, gardens, terraces and the like. The fence board made of wood plastic materials has become a favorite fence for people due to the advantages of light weight, attractive appearance, low cost, scratch resistance, weather resistance, heat resistance, cold resistance and the like.

The prior wood-plastic fence has the appearance structure shown in the patent of the utility model with the publication number of CN 203924898U. The fence panel of this construction can be widely used in the marketplace, mainly because of its ease of installation. When the fence is used, the boss 1 of the first fence plate is arranged upwards, the groove 5 of the second fence plate is aligned with the boss 1 of the first fence plate below, and the assembling between the fence plates is completed by simple splicing through the cooperation of the boss 1 and the groove 5; and because the structures of the boss 1 and the groove 5 determine that a certain self-guiding function exists between the boss and the groove, the boss and the groove do not need to be aligned during splicing, and good splicing can be completed. This greatly facilitates the installation of workers, and thus, it can rapidly spread the market.

However, since the fence board product cannot achieve zero tolerance with the design drawing, when the tolerance of two adjacent boards is large, the self-guiding function can guide the generation of macroscopic splice joints. This is also a common technical problem of such wood-plastic fences. In CN 203924898U, by providing R angles at the shoulder and bottom, the R angle at the shoulder and the R angle at the bottom of the adjacent plate are spliced into a decorative seam, so that the decorative seam is used to mask the splice seam. However, as can be seen from fig. 1 of CN 203924898U, the opening of R angle makes the contact area between the two not enough become more important, which affects the splicing stability of the adjacent plates to some extent. For example, when an upper fence panel is subjected to a sufficiently large downward force, an unexpected expansion of the groove 5 may result due to a reduction in contact area, such that the upper fence panel and its adjacent lower fence panel may have an overrun from the desired fit. Since, in general, the design depth of the recess 5 is slightly greater than the height of the boss 1 in order to ensure proper contact between the two, otherwise the intended fit will not be achieved. If the R angle is too small, the decorative seam cannot play a role in decoration, but can become a larger splicing seam in vision. Thus, opening the R angle is only a relief to some extent, and is not an ideal approach.

Disclosure of utility model

The present utility model addresses the above-described problems, thereby providing a fence panel. The fence panel solves the problem of splice seams through the special structure, ensures the contact area of adjacent fence panels, and does not exceed the expected matching problem caused by too small contact area.

The technical scheme for solving the problems is as follows:

The fence board comprises a board body made of wood plastic materials, wherein the board body comprises a board body, tenons arranged at the upper end of the board body and mortises arranged at the lower end of the board body, the tenons are upwards arranged, the mortises are downwards arranged, and the tenons and the mortises are integrally connected with the board body; the tenon comprises a tenon body and a connecting assembly, wherein the tenon body is provided with a flat male top surface, two male slope surfaces and a flat bottom surface, the two male slope surfaces are arranged in an inverted V shape, so that the tenon body presents a protruding structure, and the inner end and the outer end of the flat bottom surface respectively extend to form a first shoulder and a second shoulder; the connecting assembly comprises a first connecting part and a second connecting part which are vertically arranged; the upper end of the first connecting part is fixedly connected with the first shoulder part, and the lower end of the first connecting part is fixedly connected with the plate body; the upper end of the second connecting part is fixedly connected with the second shoulder part, and the lower end of the second connecting part is fixedly connected with the plate body; the width of the first shoulder and the second shoulder is not less than 1/6 of the thickness of the plate body.

In the technical scheme, when the upper and lower adjacent fence plates are in butt joint, the first shoulder and the second shoulder of the lower fence plate play a role in supporting the upper fence plate, and as the width of the first shoulder and the second shoulder is not smaller than 1/6 of the thickness of the fence body, the first shoulder and the second shoulder have enough widths to provide larger contact area, so that the contact pressure between the first shoulder and the second shoulder is reduced, the lower fence plate can play a role in stably supporting the upper fence plate, and the problem of splicing the V-shaped connected fence plates in the prior art is solved; in the second aspect, in the above technical solution, the first connecting portion and the second connecting portion are further provided to extend the splice seam, so that the splice seam is obviously enlarged to form a decorative seam with obviously increased width, and a good decorative effect is achieved while the splice seam is hidden. And because the width of the decorative seam is high, the problem of insufficient alignment is difficult to see under the condition that the tolerance of the upper fence plate and the lower fence plate is obvious. The alignment means that the plate surfaces of the upper fence plate and the lower fence plate are in the same plane, and the higher the alignment degree is, the smaller the distance between the plate surfaces of the upper fence plate and the lower fence plate is.

Preferably, the first connecting portion and the second connecting portion are both sheet structures.

As an preference of the above technical solution, the plate body includes an upper end face, an inner side face and an outer side face, the upper end face is used for connecting the tenon, the inner side face is connected with the inner end of the upper end face, the outer side face is connected with the outer end of the upper end face through a transition face, the transition face includes a first area with a vertical flat plate profile positioned above and a second area with an arc-shaped plate profile positioned below, the first area is in coplanar connection with the outer side face of the second connecting portion, the second area is fixedly connected with the upper end of the outer side face, and the first area and the second area are in smooth transition; the second area is bent towards the inner direction of the plate body.

In the above-described solution of the utility model, the inner and outer are defined based on the correct mounting of the fence panel. The fence panel is typically installed to isolate a building or area; in the present utility model, the interior and exterior are defined with respect to pedestrian faces toward the panels separated by the fence panel, rather than being based on the panels separated by the fence panel. Based on this scenario, there is the following definition: the side of the fence board facing the pedestrians is the outside, and the side of the fence board facing away from the pedestrians is the inside. Therefore, in the above technical scheme, the inner side surface and the outer side surface refer to the use surface of the fence plate facing away from the pedestrian and the use surface of the fence plate facing toward the pedestrian respectively. Also, the inner and outer ends, the meaning of inner and outer is based on this scenario.

In the technical scheme, the design of the transition surface not only can correctly distinguish the front side and the back side of the fence plate, but also can effectively guide out rainwater. When the rainwater is obliquely beaten in the first area, the rainwater can flow to the second area rapidly under the action of gravity, and because the second area is an arc-shaped curved surface, the rainwater can be flushed out from the edge of the arc-shaped curved surface with certain inertia instead of flowing downwards along the outer side surface, so that the rainwater can be effectively guided out, and the rainwater collecting device has the advantage of no ponding.

As a preferable aspect of the above-mentioned technical solution, a third shoulder is formed between the inner side surface and the first connecting portion, and an upper surface of the third shoulder is an inclined surface.

As described above, the inclined surface on the upper surface of the third shoulder has the advantage of no water accumulation.

Preferably, the upper surfaces of the first shoulder and the second shoulder are plane.

The upper surfaces of the first and second shoulders are planar to provide greater support to the fence panel above. The reverse slope, although better supporting, is easy to cause water accumulation and is not generally adopted.

Preferably, the tenon groove is provided with a notch matched with the tenon in shape, and the depth of the notch is larger than the height of the tenon.

When the slot depth is greater than the height of the dovetail, good splice between the upper and lower fence plates is ensured, i.e., intimate contact between the upper surfaces of the first and second shoulders and the lower end surface of the upper fence plate. Although the best fit is a slot depth equal to the dovetail height, because the produced fence plate cannot be zero-tolerance to the design dimensions, a hold-up is done in the design to ensure that the upper and lower fence plates produce a good splice.

As the optimization of the technical scheme, the mortise comprises a flat female top surface and two female sloping surfaces which are symmetrically arranged, and the two female sloping surfaces are arranged in an inverted V shape, so that the mortise presents a concave structure.

In the technical scheme, the female top surface and the male top surface are of corresponding structures, and the female surface is a concave surface, and is a flat female top surface because the female top surface is positioned at the top and is a plane; the male surface is a convex surface and is a flat top surface due to its being on top and being planar. Similarly, the concave slope surface is the surface forming the groove wall of the groove, and the surface is straight and inclined at the same time; yang Pomian refers to the outer wall surface of a raised structure that is straight and inclined.

As a preferable mode of the technical scheme, the plate body comprises a lower end face, the lower end face is provided with a notch so that the lower end face is divided into a first lower end face and a second lower end face, and the mortises are arranged at the notch; the lower ends of the two concave slope surfaces are respectively connected with the first lower end surface and the second lower end surface.

As the optimization of the technical scheme, the plate body is internally provided with a first space positioned above and a second space positioned below, and the first space and the second space are communicated with the plate body in the length direction of the plate body.

According to the technical scheme, the two spaces are arranged, so that the weight of the plate can be obviously reduced under the condition that the integral strength of the plate is not reduced.

As the optimization of the technical scheme, the first space and the second space are separated by the partition plate which is arranged in parallel with the length direction of the plate body through the plate body, and the thickness difference value between the thickness of the partition plate and any one of the plates where the upper end face, the inner side face, the outer side face, the transition face, the first lower end face and the second lower end face are positioned is not more than 2mm.

In the technical scheme of the utility model, the existence of the partition plates is the basis for forming the two spaces, and if the partition plates are too thick, the weight reduction effect cannot be optimized; and too thin a separator may cause a decrease in overall strength.

In summary, the utility model has the following beneficial effects:

1. The first connecting part and the second connecting part are arranged to extend the splice seam, so that the splice seam is obviously enlarged to become a decorative seam with obviously increased width, and good decorative effect is achieved while the splice seam is hidden;

2. The first shoulder and the second shoulder have enough widths to provide larger contact area, so that the lower fence plate can stably support the upper fence plate, and the problem of splicing V-shaped connected fence plates in the prior art is solved;

3. The design of the transition surface not only can correctly distinguish the front and back using surfaces of the fence plate, but also can effectively guide out rainwater, and has the advantage of no ponding;

4. the two spaces are arranged, so that the weight of the plate can be obviously reduced under the condition that the integral strength of the plate is not reduced.
