Abstract

The utility model discloses a plastic wrapped square lumber, wherein a plastic wrapping layer is arranged outside the square lumber, the square lumber is an integrated structure which is made of wood materials, or the square lumber is a separated type structure which is made of wood materials and/or strip wood materials, or is made of sawdust agglutination. The section of the plastic wrapped layer is a rectangle, or is a square, or is shaped like a Chinese character 'ri', or is shaped like a Chinese character 'mu'. Inwards limited crush strips are arranged on the lateral sides of the plastic wrapped layer, and limited grooves matched with the crush strips are arranged on the square lumber. The square lumber has simple structure, can reduce the usage quantity of wood materials and cost, and has good social and economic benefits.

Description

The plastic wraps type lumps of wood

One, technical field: the utility model relates to a kind of lumps of wood for building, particularly relates to a kind of plastic wraps type lumps of wood.

Two, background technology: at present, because timber is in light weight, easily saw digs, and it is convenient to construct, the general user's carpentery workshop of building engineering construction template keel and back cord material.But a large amount of harvest of forest trees must aggravate natural environment deterioration, do not meet national environmental protection policy.Except that the wood supply shortage, in construction work, the problem of a large amount of wastes of timber is also very outstanding, because the lumps of wood should be sawed and should dig, causes and arbitrarily cuts saw, the short usefulness of long material in the use, usually produces a large amount of timber losses and waste.Moreover the lumps of wood is subjected to wind and scrapes the Exposure to Sunlight meeting and the strain cracking phenomenon occurs, influences the shaping structures quality.

At this situation, people propose some measures of saving the lumps of wood or the alternative lumps of wood: adopt the metallic channel sleeve-board on the lumps of wood, play reinforcement effect, perhaps in the metal frid, fill non-wood substance, to reduce lumps of wood consumption, but this mode has increased the weight of building unit, has been with many troubles to construction, also has the problem that cost is higher, be difficult for making in addition.

Three, the content of utility model:

Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, can reduce the timber use amount and the lower-cost plastic wraps type lumps of wood.

The technical solution of the utility model is: a kind of plastic wraps type lumps of wood, contain the lumps of wood, and described lumps of wood outside is provided with the plastic wraps layer.

The described lumps of wood is an integral structure, is made by whole timber; The perhaps described lumps of wood is a split-type structural, is made and/or many timber are made by multistage timber; The perhaps described lumps of wood is made by the sawdust binder.

The described lumps of wood is one, and its cross section is rectangle, square or convex, and the cross section of described plastic wraps layer is corresponding rectangle, square or concave character type.

Perhaps, the described lumps of wood is two or three and is arranged in parallel that the cross section of each lumps of wood is rectangle, square or convex, and the cross section of described plastic wraps layer is corresponding day font or order font.

The side of described plastic wraps layer is provided with inside spacing prominent bar, and the described lumps of wood is provided with the limited impression that is complementary.Described plastic wraps layer same side is provided with two described spacing prominent bars.Be provided with opening between two spacing prominent bars on side of described plastic wraps layer, the described lumps of wood stretches out from this opening.

The beneficial effects of the utility model are:

1, the utility model lumps of wood can be a split-type structural, is made and/or many timber are made by multistage timber, also can be made by the sawdust binder.Reduce the use amount of timber, and can realize twice laid, timber interrupted, strip, sawdust etc. are combined recycling, reduce building costs.

2, the utility model adopts the plastic wraps layer, moulding easily, and low, the easy making of its cost, especially in light weight, be convenient to construction and use.

3, the utility model plastic wraps layer is provided with spacing prominent bar, and the lumps of wood is provided with the limited impression that is complementary, and makes firm the combining of the plastic wraps layer and the lumps of wood, prevents the two disengagement, increases its application life.

4, the utility model is simple and compact for structure, and is applied widely, is easy to promote, and has good society and economic benefit.

Four, description of drawings:

Fig. 1 is one of structural representation of the plastic wraps type lumps of wood;

Fig. 2 be the plastic wraps type lumps of wood structural representation two;

Fig. 3 be the plastic wraps type lumps of wood structural representation three;

Fig. 4 be the plastic wraps type lumps of wood structural representation four.

Five, the specific embodiment:

Embodiment one: referring to Fig. 1, among the figure, the lumps of wood 2 outsides of the plastic wraps type lumps of wood are provided with plastic wraps layer 1.The cross section of plastic wraps layer 1 is a rectangle, and the lumps of wood 2 is an integral structure, is made by whole timber; Perhaps the lumps of wood 2 is a split-type structural, is made and/or many timber are made by multistage timber; Perhaps the lumps of wood 2 is made by the sawdust binder.Determine as required.

Embodiment two: referring to Fig. 2, present embodiment and embodiment one are basic identical, and something in common does not repeat, and difference is: the cross section of plastic wraps layer 1 is a day font, and two lumps of wood 2 are arranged side by side.

Embodiment three: referring to Fig. 3, present embodiment and embodiment two are basic identical, something in common does not repeat, difference is: plastic wraps layer 1 same side is provided with two spacing prominent bars 3, the lumps of wood 2 is provided with the limited impression that is complementary, and be provided with opening between two spacing prominent bars 3, the lumps of wood 2 stretches out from this opening.The shape of cross section of plastic wraps layer 1 is the concave character type that two bottoms link to each other, and the bottom surface of concave character type sunk part is an opening.

Embodiment four: referring to Fig. 4, present embodiment and embodiment two are basic identical, something in common does not repeat, difference is: the side of plastic wraps layer 1 is provided with inside spacing prominent bar 3, the lumps of wood 2 is provided with the limited impression that is complementary, and makes plastic wraps layer 1 and firm the combining of side's 2 wood.

Change the lumps of wood and plastic wraps layer concrete shape, change the concrete structure of spacing prominent bar and the position be set and quantity and change metallic support sheet concrete structure and the position is set and quantity can be formed a plurality of embodiment, be common excursion of the present utility model, do not describe in detail one by one at this.
