Description

A kind of heavy bamboo guardrail

Technical field

The utility model belongs to protection guardrail, more particularly to a kind of heavy bamboo guardrail.

Background technology

China is bamboo resource country the abundantest in the world, in recent years, gradually deficient with world's timber resources, Rationally and effectively seem more and more important using timber and bamboo timber resource.

The approach that bamboo and wood materials are rationally utilized is exactly material restructuring and is combined, in the prior art, for building, filling The main Recombined bamboo technology in the fields such as decorations has thin bamboo strips used for weaving recombinant technique, bamboo fiber reinforced composite material manufacturing technology, bamboo side's restructuring skill Art, dwarf bamboo recombinant technique, bamboo wood arc recombinant technique etc..A kind of raising utilization rate of bamboo that Recombined bamboo is succeeded in developing in recent years Bamboo product, be currently used primarily in manufacture floor, also have part be used for manufacture furniture.

Additionally, recombining bamboo is divided into cold pressing Recombined bamboo and hot pressing Recombined bamboo according to the difference of processing and forming technology, wherein, it is cold After pressure Recombined bamboo general 150-300mm, 2-2.5m it is long, due to reasons such as device fabrications, length is difficult to significantly extend；Hot pressing weight Up to more than 5m, general thickness is 32mm to group bamboo length, and because heat transfer is limited, thickness is difficult to improve, it is difficult to be directly used as pillar, such as Lamination is glued, and material use is unreasonable, and the problem of heat transfer limitation is equally existed during hot pressing.Therefore, how by recombining bamboo root Used according to splicing is carried out using field, expand application field, improve the utilization rate of bamboo wood, the weight for mitigating bamboo wood turns into instantly urgently Problem to be solved.

Authorization Notice No. discloses a kind of hollow reconsolidated bamboo column for the patent of CN202264271U, belongs to bamboo processing utilization Technical field, it includes that, in the recombined bamboo plate of rectangular structure, described recombined bamboo plate head and the tail pass through splicing or joggle, together When by bond constitute hollow structure square column body structure, it has simple structure, the characteristics of reasonable in design, shows： On the one hand weight is mitigated, by the utilization rate that material is improve using hollow-core construction；Secondly with reference to convenient and reliable, the knot of hollow beam Conjunction mode, in faying face applying glue, is divided into splicing, tongue-and-groove combination, pole tenon with reference to three kinds, improves stock utilization.

A kind of Authorization Notice No. Recombined bamboo assembly hedge guardrail for the patent of CN204252639U is provided, including support Frame, transverse slat component and connects bearing, the transverse slat component include Recombined bamboo transverse slat and are fixedly connected on Recombined bamboo transverse slat two ends End support saddle, the connects bearing is socketed on support frame, and connects bearing is hexahedron main body, and one is set on each outerplanar Individual connection boss, connection boss is provided with buckling groove, and the center of connects bearing is a hexagon through hole, and support frame as described above is by six The column of side shape and be fixedly connected on column lower end base constitute, the end support saddle that the transverse slat component is set by its two ends It is plugged in the buckling groove set on connection boss.

But, notification number uses right angle tenon or square tongue-and-groove by two groups of Recombined bamboos for CN202264271U prior arts Sheet material carries out head and the tail splicing, however, this right angle tenon or square tongue-and-groove connecting method, between two groups of head and the tail splicing recombined bamboo plates Joint tongue button and insecure so that must by junction imposing adhesive, to carry out reinforcement glued, lose tenon buckle it is solid The meaning of connection, while the adhesive for applying increased pollutant composition, reduces the ecological friendly and the feature of environmental protection of sheet material, limits Having made tenon type structure later stage material may deform the change of generation.And notification number for CN204252639U prior art in mainly exist It is the assembling technique between support frame, transverse slat component and connects bearing in the component of hedge guardrail, does not propose as support frame, horizontal stroke The component of the recombining bamboo of board component base material and its problem of connection.

Based on previous reasons, the utility model provides a kind of heavy bamboo guardrail, can not only realize between two groups of recombining bamboos Firmly connection, and realize the quick tenon button connection of sheet material, it is to avoid the use of screw；Meanwhile, tenon type structure has ensured the later stage Material may deform the change of generation；Additionally, the weight of hollow structure square column heavy bamboo section bar reduction recombining bamboo, reduces into This, improves the utilization rate of recombining bamboo resource.

The content of the invention

The purpose of this utility model is exactly that the component of the heavy bamboo guardrail is hollow to provide a kind of new heavy bamboo guardrail Square heavy bamboo cylinder, and the hollow square heavy bamboo cylinder uses prefabricated tenon buckle structure, can not only realize hollow square heavy bamboo Quick tenon between column member is buckled and is solidly connected, and avoids the use of screw, and tenon type structure has ensured that later stage material can The change for producing can be deformed；The weight of recombining bamboo is reduced, reduces cost improves the utilization rate of recombining bamboo resource.

In order to realize above-mentioned target, the technical scheme for using for：A kind of heavy bamboo guardrail described in the utility model includes vertical Post, horizontal bar and subfield, its design feature is the column, horizontal bar is hollow square heavy bamboo cylinder, the hollow square heavy bamboo post Body is formed by two groups of male tenon heavy bamboo sheet materials, two groups of female tenon heavy bamboo sheet materials through male-female engagement tenon buckle structure joggle.

The tenon buckle structure is made up of the tongue-and-groove that the tenon in convex shape matches with concave and with convex shape tenon, The tenon is arranged on the both sides longitudinal edge of public tenon heavy bamboo sheet material, and the both sides that the tongue-and-groove is arranged at female tenon heavy bamboo sheet material are indulged To on edge.

The tenon buckle structure is using 45 ° of angle-inserting type tenon buttons, double-deck tenon button, buckle type tenon button, zip mode tenon button, formula tenon fond of gossip One of button or 3 D stereo skewed slot tenon button are planted, wherein the tenon buckle structure is preferably 3 D stereo skewed slot tenon button.

The tongue-and-groove, tenon in isosceles trapezoid shape or right-angled trapezium shape that one of base angle is 45 °, wherein the tenon The preferred base angle of groove, tenon is 45 ° of right-angled trapezium shape.

The hollow square heavy bamboo cylinder includes hollow square build heavy bamboo cylinder and hollow cuboid-type column heavy bamboo post Body.

The heavy bamboo sheet material includes cold pressing heavy bamboo sheet material, hot pressing heavy bamboo sheet material.

Used as further preferred scheme, the heavy bamboo guardrail also includes that the subfield is hollow square heavy bamboo cylinder.

The beneficial effect that the utility model is realized：The utility model uses the hollow square heavy bamboo cylinder of prefabricated tenon buckle structure Component, can not only realize that the quick tenon between hollow square heavy bamboo column member is buckled and be solidly connected, and avoid making for screw With tenon type structure has ensured that later stage material may deform the change of generation；The weight of recombining bamboo is reduced, reduces cost is improved The utilization rate of recombining bamboo resource, can completely substitute existing indoor and outdoor and be used for manufacturing guardrail, the anticorrosive wood of wayside pavilion or solid wood. Therefore, the utility model has very strong practicality, easy to use, with preferable economic worth and social value.
