Abstract
The utility model discloses a steel and wood composite beam for a construction formwork. The steel and wood composite beam for the construction formwork comprises a wood beam body and a steel tube, wherein the wood beam body is sleeved with the steel tube, the cross section of the steel tube is of a rectangular shape, and at least one face plate of the steel tube is thinner than the other face plates. The rectangular tube is used, the rectangular tube is composed of the thick plates and the thin plates, and nails can be easily hammered into the thin plates. The four faces of the rectangular tube are respectively provided with a hole or a through groove, the structure is complete, and the rectangular tube is not prone to deformation when force is exerted on the rectangular tube. Meanwhile, the two ends of the wood beam body can make contact with water, other portions of the wood beam body are isolated from water, the wood beam body is made to be in a dry state for a long time, and therefore long-term use can be facilitated.
Description
Technical field
The utility model relates to a kind of construction tool for building, relates in particular to a kind of wood of clad steel for building operations formwork a tree, used in making timber for boats.
Background technology
Building of steel concrete first used the template moulding usually in building trade, and the template of moulding supports by wooden a tree, used in making timber for boats.And the wooden a tree, used in making timber for boats rate of recovery is very low, the waste is larger.At present, in the construction of domestic construction industry, the casting reinforced concrete molding component mainly adopts compound wood brace.The structure of existing compound wood brace is to be embedded wooden a tree, used in making timber for boats in steel framework mostly, wherein is provided with groove on steel framework face, or large hole.Thus, the one side of compound wood brace and template contact is that stressed rear easily the expanding outwardly with wooden a tree, used in making timber for boats of steelframe on template contact surface both sides separated and be out of shape; Wood a tree, used in making timber for boats large tracts of land is exposed, easily suction, the application life of the wooden a tree, used in making timber for boats of shortening.
The utility model content
Given this, the purpose of this utility model is to provide a kind of compound wood brace of not yielding, long service life.
For solving above technical problem, the technical scheme that the utility model provides is that a kind of wood of clad steel for building operations formwork a tree, used in making timber for boats is provided, comprise wooden a tree, used in making timber for boats, be set in the steel pipe on wooden a tree, used in making timber for boats, the cross section of described steel pipe is rectangle, and at least one panel of steel pipe is thinner than other panels.
Preferably, described rectangle is square.
Preferably, the gauge of sheet of described steel pipe be slab thickness 1/2.
Be provided with along its length bar-shaped trough at least one face of described wooden a tree, used in making timber for boats, a face laminating at bar-shaped trough place on a thin plate of steel pipe and wooden a tree, used in making timber for boats.
Be embedded with cushion course in described bar-shaped trough.
Described cushion course is cystosepiment.
The width of described bar-shaped trough be bar-shaped trough place face width 1/3 ~ 1/2.
Compared with prior art, the utlity model has following advantage:
1, the utility model has used quarter bend, and this quarter bend is divided into slab and thin plate, and thin plate is easily worn by the nail nail.On four faces of quarter bend, hole or groove are not set, structural integrity, not yielding when it is stressed.Simultaneously, except wooden a tree, used in making timber for boats two ends can touch water, other positions of wooden a tree, used in making timber for boats all isolate with water, make wooden a tree, used in making timber for boats be in for a long time dry state, are more conducive to long-term use.
2, after nail passes thin plate, the place of penetrating can produce inside pointed projections, is provided with bar-shaped trough on wooden a tree, used in making timber for boats of the present utility model, prevents from hindering and changing wooden a tree, used in making timber for boats in the wooden a tree, used in making timber for boats of pointed projections insertion.
3, be provided with cushion course in bar-shaped trough of the present utility model, this cushion course preferred foams plate.After compound wood brace was reused, thin plate can stay some holes,, by this cystosepiment, can prevent that sealing enters in compound wood brace.

The specific embodiment
Describe below in conjunction with accompanying drawing and specific embodiment.
Embodiment 1:
Referring to Fig. 1 to Fig. 3.The described a kind of wood of clad steel for the building operations formwork a tree, used in making timber for boats of the present embodiment, comprise wooden a tree, used in making timber for boats 1, is set in the steel pipe 2 on wooden a tree, used in making timber for boats, and the cross section of described steel pipe 2 is rectangle, and namely this steel pipe is quarter bend, and four faces of steel pipe 2 are complete steel plate.As preferably, this rectangle is square.Four panels of steel pipe 2 are respectively a thin plate and three slabs, gauge of sheet be slab thickness 1/2.
Embodiment 2:
Referring to Fig. 4.The described a kind of wood of clad steel for the building operations formwork a tree, used in making timber for boats of the present embodiment, comprise wooden a tree, used in making timber for boats 1, is set in the steel pipe 2 on wooden a tree, used in making timber for boats.The cross section of steel pipe 2 be the square, four panels of steel pipe 2 are respectively a thin plate and three slabs, gauge of sheet be slab thickness 1/2.Wood a tree, used in making timber for boats 1 a face on middle part be provided with along its length bar-shaped trough 3, the cross section of this bar-shaped trough is rectangle, the width of bar-shaped trough 3 be bar-shaped trough place face width 1/3.The face at bar-shaped trough place laminating on the thin plate of steel pipe 2 and wooden a tree, used in making timber for boats.
Be embedded with cushion course 4 in bar-shaped trough 3, this cushion course 4 is cystosepiment.
Be below only preferred embodiment of the present utility model, should be pointed out that above-mentioned preferred embodiment should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with the claim limited range.For those skilled in the art, within not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
