Description
Technical Field
The utility model relates to the technical field of building construction, in particular to a novel steel-wood keel for buildings.
Background
The steel-wood keel is a house structure, the structure is made of wood materials and steel materials, if a proper keel needs to be selected in the house decoration process, the comprehensive consideration needs to be combined according to the house structure, construction process, price and the like, the steel-wood keel not only can enable a house to be firmer and firmer, but also can enable the house to be more attractive, the steel-wood keel has the advantages of energy conservation, material conservation, cost conservation, engineering quality improvement, construction efficiency improvement and the like due to the steel-wood keel product, the basic national policy of energy conservation and emission reduction is implemented, the effects of saving resources, labor and cost are achieved, the combination between the wood keel and the steel sleeve of the existing steel-wood keel is not firm, and the wood keel is easy to fall off from the steel sleeve, so that the normal construction is influenced.
SUMMERY OF THE UTILITY MODEL
Therefore, a novel steel-wood keel for buildings needs to be provided, and the problem that the core of the existing steel-wood keel is easy to loose is solved.
In order to achieve the purpose, the utility model provides a novel steel-wood keel for buildings, which comprises an inner keel and a steel sleeve, wherein the inner keel is positioned in the steel sleeve, the outer diameter of the inner keel is matched with the inner diameter of the steel sleeve, the steel sleeve comprises a steel sleeve main body and contraction parts fixed at two ends of the steel sleeve main body, and the cross sectional area of the contraction parts is smaller than that of the steel sleeve main body.
Further, the contraction part is pyramid-shaped, the contraction part of the pyramid shape comprises an expansion end and a contraction end, and the expansion end corresponds to the end part of the steel sleeve main body.
Further, the contraction part and the steel sleeve main body are of an integral structure.
Further, the specification of the steel sleeve main body is 5cm × 5cm, and the specification of the contraction end of the contraction portion is 4.5cm × 4.5 cm.
Further, the inner keel is made of carbonized wood or anticorrosive wood.
The technical scheme has the following beneficial effects:
according to the utility model, the steel sleeve is provided with the contraction part, the contraction part can be manufactured or installed after the inner keel is installed on the steel sleeve, and when the steel sleeve is used, the inner side surface of the contraction part tightly supports against the outer side surface of the inner keel, so that the inner keel can be effectively prevented from falling off from the steel sleeve.
Drawings
Fig. 1 is a structural diagram of a steel-wood keel according to a specific embodiment.
Description of reference numerals:
1. an inner keel; 2. steel dragon sleeves; 21. a constriction; 22. a steel jacket body.
Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1, the embodiment provides a novel steel-wood keel for buildings, which includes an inner keel 1 and a steel jacket 2, wherein the inner keel 1 is located in the steel jacket 2, an outer diameter of the inner keel 1 is matched with an inner diameter of the steel jacket 2, the steel jacket 2 includes a steel jacket main body 22 and a contraction portion 21 fixed at two ends of the steel jacket main body 22, and a cross-sectional area of the contraction portion 21 is smaller than a cross-sectional area of the steel jacket main body 22. The constriction 21 is pyramid-shaped, and the pyramid-shaped constriction 21 includes an expanded end corresponding to the end of the steel jacket body 22 and a constricted end.
The contraction part 21 and the steel sleeve main body 22 are of an integral structure, the specification of the steel sleeve main body 22 is 5cm multiplied by 5cm, and the specification of the contraction end of the contraction part 21 is 4.5cm multiplied by 4.5 cm. The length of the constricted portion 21 is 3 cm.
The inner keel 1 is made of carbonized wood, and the inner keel 1 in another embodiment is made of anticorrosive wood.
When the steel-wood keel contraction device is used, the inner keel 1 is embedded into the steel sleeve 2, then the square steel pipe necking machines are used for extruding the four sides of the two ends of the steel-wood keel, the length of a 5 multiplied by 5cm square steel port is 3cm, the steel keel is contracted into 4.5 multiplied by 4.5cm, the steel sleeve 2 is divided into the contraction part 21 and the steel sleeve main body 22, the contraction part 21 tightly presses the inner keel 1, the contraction parts 21 at the two ends of the steel sleeve main body 22 are fixed to the inner keel 1 in an extruding mode, and the inner keel 1 is effectively prevented from being separated from the steel sleeve 2.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or terminal that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or terminal. Without further limitation, an element defined by the phrases "comprising … …" or "comprising … …" does not exclude the presence of additional elements in a process, method, article, or terminal that comprises the element. Further, herein, "greater than," "less than," "more than," and the like are understood to exclude the present numbers; the terms "above", "below", "within" and the like are to be understood as including the number.
