Description

Imitation wood building and its steel-wood connection structure

technical field

The invention relates to the technical field of imitation wood building, more specifically, it relates to imitation wood building and its steel-wood connection structure.

Background technique

Imitation wood building is a kind of building that looks like wood, but is actually other structures. Other structures usually use cement and stone.

In the field of imitation wood construction, although cement or stone structures have the characteristics of saving wood, preventing insect corrosion, and improving structural safety, they have the disadvantages of heavy component weight, inconvenient installation, difficulty in matching with related structures, and greater environmental pollution during construction and dismantling. In order to achieve the same effect as the wooden structure after painting, high requirements are put forward for the production and installation of imitation wood components.

Now there are also imitation wood building construction schemes using steel structures, which have many advantages compared to cement and stone construction techniques, such as lighter weight and easy installation. However, in the prior art, there has always been a situation in which the connection between the wooden structure and the steel structure is not firm enough.

Therefore, the Chinese patent whose notification number is CN204919828U discloses a connection structure between wooden beams and steel structural columns of an antique building. The steel sleeve is arranged vertically to the steel structure column, the end of the wooden beam is inserted into the steel sleeve, and a plurality of tension bolts are arranged on the steel sleeve.

When it is necessary to connect the wooden structure with the steel structure, the wooden beam and the steel structure column can be firmly connected through the cooperation of the steel sleeve and multiple pull bolts.

However, in practical applications, because the nuts on the pull bolts are relatively close to the steel structure columns, when it is necessary to install or remove wooden beams, the tools used by workers are difficult to insert, which causes inconvenience during installation or removal, and makes installation or removal difficult. It is inconvenient to disassemble imitation wood buildings.

Contents of the invention

In view of the shortcomings of the above-mentioned prior art, the first object of the present invention is to provide a steel-wood connection structure, which has the advantage of being convenient for workers to install and disassemble steel structure support columns and wooden beams.

The length direction of the structural support column is set, the end of the wooden beam is plugged into the steel sleeve, the steel sleeve is pierced with a screw that penetrates the wooden beam, and the screw is away from the steel structural support column along its head, and the bottom is The direction close to the supporting column of the steel structure is arranged obliquely, the bottom of the screw is threaded with a fastener, the outer surface of the steel sleeve is fixedly provided with a protrusion, and the protrusion and the fastener abut and fit, and The abutting surfaces of the protrusion and the fastener are parallel to each other.

By adopting the above-mentioned technical scheme, the protrusions allow workers to have more space for tightening or loosening the fasteners when installing and dismounting the steel structure support columns and wooden beams, compared with the fasteners directly attached to the steel sleeves, so the It is easier to install and install; in addition, the screw is inclined along the direction where the head is away from the steel structure support column and the bottom is close to the steel structure support column, so that it is convenient for the worker to move the screw from the direction of the screw along its axis after the fastener is loosened. The head is pulled out; the abutting and mating surfaces of the protrusion and the fastener are parallel to each other, so that the contact area between the fastener and the protrusion is the largest, the degree of abutment is higher, and the degree of locking is firmer.

Preferably, the fastener includes a nut and a washer sleeved on the screw, and the washer is located between the protrusion and the nut.

By adopting the above technical solution, the cooperation between the nut and the screw is simple and practical, and the washer increases the abutment area between the nut and the protrusion, so that the locking degree of the nut is higher.

Preferably, the steel sleeve is provided with a clamping groove for snap-fitting with the head of the screw.

By adopting the above technical scheme, the worker only needs to rotate the nut when loosening the nut to disassemble the wooden beam; it reduces the situation that the screw rotates with the nut as a whole when the worker loosens the nut, thereby reducing the disassembly efficiency of the worker.

Preferably, the head of the screw is polygonal.

By adopting the above technical solution, the head of such a screw has a plurality of edges, which are clipped and matched with the slot, so as to ensure that the screw will not rotate easily when the nut is loosened.

Preferably, a rib is provided between the steel sleeve and the steel structure support column.

By adopting the above technical scheme, the rib plate can improve the supporting effect of the steel sleeve on the wooden beam, and the bearing strength is higher.

Preferably, the outer wall of the steel structure support column is covered with wood boards.

By adopting the above technical solution, the wooden board makes the appearance of the steel structure support column more beautiful, and improves the aesthetics of the whole imitation wood building.

Preferably, the wall thickness of the steel sleeve is between 12mm and 15mm.

By adopting the above-mentioned technical scheme, the steel sleeve can better bear the wooden beam, and the structural strength of the steel sleeve can be guaranteed, and the practicability is good.

The second object of the present invention is to provide an imitation wood building, which utilizes the above-mentioned steel-wood connection structure, which facilitates the installation and removal of wooden beams by workers, and further facilitates the installation and disassembly of the imitation wood building by workers.

In order to achieve the above object, the present invention provides the following technical solutions: a wood-like building, including four steel structure support columns fixedly installed on the ground and sequentially connected to form a rectangle, and fixedly installed directly above the four steel structure support columns The roof is characterized in that it includes the steel-wood connection structure according to any one of claims 1 to 7; the top ends of the four steel structure support columns are sequentially connected with wooden beams, and the wooden beams and the steel There are steel-wood connection structures between the structural support columns.

By adopting the above technical scheme, when installing or dismantling the imitation wood building, the steel structure support columns and wooden beams connected by the steel-wood connection structure facilitate the installation or disassembly of the worker, thereby facilitating the installation and disassembly of the imitation wood building by the worker.

Preferably, the bottom end of the steel structure support column is fixedly installed with a base, and the base is fixedly installed on the ground through pull-out screws.

By adopting the above technical solution, the base increases the area where the steel structure support column contacts the ground, thereby making the steel structure support column more stable. In addition, the base fixed by bolts is convenient for workers to disassemble and install.

In summary, the present invention has the following beneficial effects:

The protrusions allow workers to install and disassemble steel structure support columns and wooden beams, compared with directly attaching to the steel sleeve, the operation space for tightening or loosening the fasteners is larger, so disassembly and installation are easier; in addition, the screws along the Its head is away from the steel structure support column, and the bottom is inclined to the direction of the steel structure support column, so that it is convenient for the worker to pull the screw out from the head of the screw along its axis after the fastener is loosened; the protrusion and fastening The abutting and mating surfaces of the fasteners are parallel to each other, so that the contact area between the fastener and the protrusion is the largest, the abutment degree is higher, and the locking degree is firmer.
