Description
Technical field
The utility model belongs to raw bamboo Architectural Structure Design field, is related to a kind of bamboo bar with screw shell built-in fitting and connects
Long structure.
Background technique
Under the energy-saving and environment-friendly main trend in the whole world, breeding is easy, growth is fast, becomes a useful person morning and yield height etc. due to having for bamboo
Feature has been widely used in building structure, especially in some more earthquake areas or the area that goes sightseeing, however is carrying out bamboo
In the process of construction of building, it is often necessary to be attached two raw bamboos, i.e. bamboo bar spreading, existing connection type is directly by two
Root raw bamboo is bundled by rope, however this mode will lead between two raw bamboos that there are laps after connecting, thus
The spreading that cannot greatly realize bamboo bar, causes the axle center of two bamboo bars to be not arranged on the same straight line, can not preferably into
Row power transmission, while it being easy to appear the phenomenon that two raw bamboos are mutually rolled and fallen off, globality is poor.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts provides a kind of pre-buried with screw shell
The bamboo bar spreading structure of part, the globality of the structure is preferable, and can realize the spreading of bamboo bar to the greatest extent.
In order to achieve the above objectives, the bamboo bar spreading structure described in the utility model with screw shell built-in fitting includes the
One steel bushing, the second steel bushing, the first raw bamboo and the second raw bamboo；
One end of first steel bushing is inserted in the first raw bamboo along the end of the first raw bamboo, and one end of the second steel bushing is along
The end of two raw bamboos is inserted in the second raw bamboo, and external screw thread, the second steel bushing are provided on the outer wall of the first steel bushing other end
The internal screw thread matched with the external screw thread is provided on the inner wall of the other end, the outer wall of the first steel bushing is interior with the first raw bamboo
High performance concrete is filled between wall and between the outer wall of the second steel bushing and the inner wall of the second raw bamboo.
It is offered on the side wall of first raw bamboo and on the side wall of the second raw bamboo several for supplying water what slurry penetration passed through
Through-hole.
It is carved on the outer wall of first steel bushing and on the outer wall of second steel bushing and is equipped with scratch or decorative pattern.
The end of first raw bamboo and the end of the second raw bamboo are provided with ring or are socketed with cuff.
The diameter of first raw bamboo is different from the diameter of the second raw bamboo.
The first through hole for passing through for the first steel bushing is provided on the ring of first raw bamboo, on the ring of the second raw bamboo
It is provided with the second through-hole for passing through for the second steel bushing.
The utility model has the following beneficial effects:
Bamboo bar spreading structure described in the utility model with screw shell built-in fitting is when specific operation, the first steel bushing
Cylinder is inserted in the first raw bamboo, and the second steel bushing is inserted in the second raw bamboo, is passed through between the first steel bushing and the second steel bushing
It is threadedly coupled, to realize the connection of the first steel bushing and the second steel bushing, the inner wall of the outer wall of the first steel bushing and the first raw bamboo
Between and the second steel bushing outer wall and the second raw bamboo inner wall between be filled with high performance concrete, to realize the first steel
The connection of sleeve and the first raw bamboo, while realizing the connection of the second raw bamboo and the second steel bushing, to avoid the first raw bamboo, second
There is relative displacement between raw bamboo, the first steel bushing and the second steel bushing, to improve the globality of the first raw bamboo and the second raw bamboo,
And it avoids partly overlapping between the first raw bamboo and the second raw bamboo, to greatly realize the spreading of bamboo bar.
Detailed description of the invention
The structural schematic diagram of Fig. 1 the utility model.
Wherein, 1 it is the first raw bamboo, 2 be the second raw bamboo, 3 be the first steel bushing, 4 is the second steel bushing.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1, the bamboo bar spreading structure described in the utility model with screw shell built-in fitting includes the first steel
Sleeve 3, the second steel bushing 4, the first raw bamboo 1 and the second raw bamboo 2；One end of first steel bushing 3 is inserted into along the end of the first raw bamboo 1
In in the first raw bamboo 1, one end of the second steel bushing 4 is inserted in the second raw bamboo 2 along the end of the second raw bamboo 2, the first steel bushing 3
It is provided with external screw thread on the outer wall of the other end, is provided on the inner wall of 4 other end of the second steel bushing and is matched with the external screw thread
Internal screw thread, between the outer wall of the first steel bushing 3 and the inner wall of the first raw bamboo 1 and the outer wall of the second steel bushing 4 and second former
High performance concrete is filled between the inner wall of bamboo 2, the diameter of the first raw bamboo 1 is different from the diameter of the second raw bamboo 2.
Several slurry penetrations that are used to supply water are offered on the side wall of first raw bamboo 1 and on the side wall of the second raw bamboo 2 to pass through
Through-hole, in casting concrete, cement slurry penetrates through the through-hole, realizes the more preferable connection of raw bamboo and cement slurry.
It carves on the outer wall of first steel bushing 3 and on the outer wall of the second steel bushing 4 and is equipped with scratch or decorative pattern, with more the
Bite force between one steel bushing, 3 outer wall and 4 outer wall of the second steel bushing and high performance concrete；The end of first raw bamboo 1 and
The end of two raw bamboos 2 is provided with ring, and first for passing through for the first steel bushing 3 is provided on the ring of the first raw bamboo 1
