Abstract

The utility model discloses a kind of sleeper structure, comprise sleeper body (1) and metal shell (2), this metal shell (2) is coated on the external surface of sleeper body (1), both are close together, the two ends of described metal shell (2) are embed the inner sharp end (2-1) of described sleeper body (1), and it embeds angle beta and is more than or equal to 60 °, the bottom of described metal shell (2) and side stamp out many rows and embed inner triangle staple thorn (3) of sleeper body (1), this nail thorn (3) place plane and metal shell (2) place plane orthogonal, be positioned at nail thorn (3) interlaced arrangement between row and row in same metal shell (2) plane, this sleeper structure has better strength and stiffness, metal shell two ends are set to sharp end, and be embedded in sleeper body, can effectively prevent sleeper in use, the top of metal shell is surprisingly peeled off, its structure is simple, anti-bending strength is good, long service life, be suitable for and apply.

Description

A kind of sleeper structure

Technical field

The utility model relates to a kind of sleeper, specifically for supporting template in construction work.

Background technology

In construction work, generally involve and use sleeper to support some template.Traditional sleeper is directly used in support after timber is processed into required form, due to timber self-characteristic, in use its flexural strength is not enough, easily exposed to the weather and the impact of sleety weather etc., its service life is shorter, so need periodic replacement, need the timber of at substantial, thus add use cost.In addition, because the intensity of timber own is not high, when supporting template, needing to arrange that intensive sleeper could arrive the requirement supported, thus adding construction volume.

Traditional way is direct layer of metal plate on sleeper external surface cover, to increase the intensity of sleeper.But its drawback is that the binding ability of steel bushing and sleeper outer wall is too poor, and after used a period of time, metal easily tilts or bulge, and the deadweight of whole sleeper is excessive, and anti-bending strength is poor, thus increases construction intensity.

So need a kind of sleeper at present badly, the requirement of strength and stiffness can be met, there is better anti-bending strength again, longer service life.

Utility model content

For above-mentioned deficiency, main purpose of the present utility model is to provide a kind of sleeper structure, and this sleeper structure, compared to traditional sleeper structure, has better strength and stiffness, also has better anti-bending strength, longer service life.

The utility model is realized by such technical scheme:

A kind of sleeper structure, comprising:

Sleeper body and metal shell, this metal shell is coated on the external surface of sleeper body, and both are close together, and the two ends of described metal shell are the sharp end embedding described sleeper body interior, and it embeds angle beta and is more than or equal to 60 °;

Wherein, the bottom of described metal shell and side stamp out the triangle staple thorn that many rows embed sleeper body interior, and this nail thorn place plane and metal shell place plane orthogonal, the nail be positioned in same metal shell plane stings interlaced arrangement between row and row.

Further, the length of described nail thorn is less than 10mm, and the spacing with nail thorn is less than or equal to 30mm, between increase metal shell and sleeper body while binding ability, also reduces manufacture difficulty and the operation of sleeper structure, is easy to production and processing.

Further, the thickness of described metal shell is less than or equal to 1.5mm.

Further, described metal shell is steel part or Al-alloy products.

Owing to have employed said structure, the utility model adopts metal shell dual structure that is coated and embedding sleeper body to be made into sleeper, compared to existing sleeper structure, there are better strength and stiffness, metal shell two ends are set to sharp end, and be embedded in sleeper body, can effectively prevent sleeper in use, the top of metal shell is surprisingly peeled off, the side of metal shell and bottom all arrange the nail thorn of multi-row staggered layout, this nail thorn can directly punching press hammer in sleeper body, be convenient to processing and manufacturing, not only strengthen the bonding tightness between metal shell and sleeper body, both binding abilities are better, the strength and stiffness that simultaneously also avoid metal shell are subject to the impact brought when punching press nail stings, its structure is simple, anti-bending strength is good, long service life, be suitable for and apply.

Fig. 2 is I shown in Fig. 1-I sectional view.

Fig. 3 is the bottom view of this case sleeper structure.

Fig. 4 is II shown in Fig. 3-II sectional view.

Detailed description of the invention

In order to clearly understand the purpose of this utility model, technical scheme and beneficial effect, below in conjunction with accompanying drawing, the utility model is described further, but protection domain of the present utility model is not limited in the examples below.

As shown in Figure 1 to Figure 3, a kind of sleeper structure, comprise sleeper body 1 and metal shell 2, this metal shell 2 is coated on the external surface of sleeper body 1, and both are close together, and the two ends of described metal shell 2 are the sharp end 2-1 embedding described sleeper body 1 inside, to strengthen the binding ability of metal shell 2 and sleeper body 1, the angle beta of two sharp end 2-1 embedding sleeper body 1 inside is more than or equal to 60 °, and during effectively to prevent from using, metal shell 2 is unexpected peels off, and strengthens security performance; Wherein, the bottom of described metal shell 2 and side stamp out the triangle staple thorn 3 that many rows embed sleeper body 1 inside, this nail stings 3 place planes and metal shell 2 place plane orthogonal, with the bonding tightness of further reinforcement metal shell 2 with sleeper structure, and nail thorn 3 interlaced arrangement be between row and row positioned in same metal shell 2 plane, prevent when to nail thorn 3 punch forming, adjacent nail thorn 3 is affected; As preferably, the length of nail thorn 3 is less than 10mm, and the spacing with nail thorn 3 is less than or equal to 30mm, and the thickness of described metal shell 2 is less than or equal to 1.5mm; Described metal shell 2 can be steel part or Al-alloy products, also can be the good metal product of other antiseptic properties, is not particularly limited at this; Described nail thorn 3 can after the coated good sleeper body of metal shell 2, and direct punching press hammers in sleeper body 1, not only can strengthen sleeper body 1 and the binding ability of metal shell 2, also be convenient to processing and manufacturing, reduce manufacturing cost further.

More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
