Abstract
The invention relates to a sleeve for connecting wood structural members and a connecting method, and aims to provide a connecting sleeve between the wood structural members and a method for connecting the wood structural members by using the connecting sleeve.
Description
Technical Field
The invention belongs to the technical field of civil engineering, and particularly relates to a sleeve for connecting a wood structural member and a connecting method.
Background
The wood structure building has various forms and flexible layout, and the structure in the building can be easily changed according to the requirement. In the aspect of stress performance, the wood has good compression resistance, bending resistance and tensile resistance, and particularly has good plasticity in compression resistance and bending resistance, so that the wood structure house structure system is applied to many countries all over the world, along with the continuous improvement of the living standard of people in China, modern wood structure houses, villas and apartments appear in many areas in China, the industrialization, standardization and matched installation technology of wood structure buildings are realized in China, but the development of the wood structure buildings in China is slow and is only limited to low-rise commercial buildings and public buildings, but the development of the wood structure building system to multi-rise and high-rise assembled buildings becomes the subject of research of scholars at home and abroad.
At present, the factory production of the wood structure in China just starts, the field assembly technology is deficient, the treatment of the large connecting joint of the cross section size of the wood structure member is not perfect, a bolt connecting joint form is generally adopted, the tightness and the toughness are good, the manufacture is simple, the connecting mode is common in the wood structure, a bolt directly penetrates through the wood structure member through a hole, however, a gap is formed between the bolt and the hole wall, the stress between the bolt and the hole wall is not uniform due to the gap, the local bearing stress of the bolt hole is large, no matter whether wood used by the wood member is cross grains or straight grains, the wood member can be damaged along the grains of the wood, and the bolt connecting bending rigidity is greatly reduced.
Due to the defects, when the wood structures are connected, holes are drilled in the wood structures at present, and thin-wall sleeves are placed in the holes, so that gaps between bolts and hole walls are reduced, but the problem that local bearing stress at the bolt holes is large still exists in the technology, and meanwhile, chemical adhesives are added during construction, so that human health is harmed.
Disclosure of Invention
The invention aims to provide a connecting sleeve between wood structural members and a method for connecting the wood structural members by using the connecting sleeve, so as to solve the problems of stress concentration, wood grain damage and harm to human health caused by using a chemical adhesive in the existing wood structural member connecting structure.
In order to achieve the above object, the present invention provides a sleeve for connecting wood structural members, which is characterized in that: the outer wall circumferential surface at sleeve both ends is equipped with the mechanism that can imbed in the timber structure spare.
The sleeve is divided into two sleeves in the middle, the broken part of one sleeve is processed into a step shape, and the two sleeves are sleeved and stopped on the step surface.
The mechanism capable of being embedded in the wood structural member is a plurality of blades or cones.
The height of the blade or the cone is 2-3mm.
The blades are butted to form a saw-tooth shape.
The invention also provides a wood structural member connecting method, which is characterized by comprising the following steps:
1) Punching according to the connecting node position of the wood structural member;
2) Placing the sleeve in cooling equipment, and determining cooling time according to physical parameters of steel used by the sleeve;
3) And placing the cooled sleeve into the connected wood structural member, and after the wood structural member is restored to the room temperature, penetrating a bolt through the sleeve and fastening the bolt by using a nut to complete the connection.
The length of the sleeve is not less than that of the connected wood structural member, so that the wood structural member is prevented from being damaged during connection and fixation.
The invention has the advantages that:
the mechanism capable of being embedded into the wood structural member is processed on the outer walls at the two ends of the sleeve, and the sleeve is processed through the cooling equipment, so that when the mechanism is used for connecting the wood structural member, the sleeve expands due to temperature change to generate pressure, the mechanism capable of being embedded into the wood structural member is embedded into the wood structural member, the problem of local bearing stress concentration at a bolt hole is solved, the ductility and the pressure resistance of a connecting node are greatly improved, the overall anti-seismic performance of the wood structural building is improved, the use of chemical binders is avoided, and the harm of chemical harmful substances to human health is reduced.
Drawings
FIG. 1 is a schematic view of an integral sleeve of the present invention;
FIG. 2 is a schematic view of a split sleeve;
fig. 3 is a schematic view of the sleeve in use.
Detailed Description
Referring to fig. 1, the embodiment of the present invention is: the outer walls of the two ends of the integral sleeve 1 are provided with a plurality of blades 2, and all the blades are butted to form a saw-tooth shape. The blade can be replaced by a pyramid, so that the blade is easier to embed.
Referring to fig. 2, the sleeve with blades 2 at two ends is divided into a sleeve I3 and a sleeve II 4 in the middle, wherein the broken part of the sleeve II is processed into a stepped sleeve, and the two sleeves are sleeved and stopped at a stepped surface 5.
Referring to fig. 3, the method for connecting the wooden structural members includes the steps of:
1) After the wood beam 6 is manufactured in a prefabricating and processing factory, accurately measuring the position and the size of a wood structural part needing to be perforated;
2) The sleeve 1 is placed in cooling equipment, the temperature change of the cooling equipment is controlled through the physical properties of the sleeve, and the volume change of the sleeve in the cooling equipment is ensured;
3) When the set temperature requirement is met, the sleeve 1 is taken out and penetrates through the three wood beams 6 to be placed in the sleeve, the sleeve can change in volume along with the rise of the external temperature, so that the blades 2 at the end parts of the two sides of the sleeve are completely embedded into the wood beams at the two ends, when the wood beams are recovered to the room temperature, the bolts 7 penetrate into the wood beams, and the nuts 8 are screwed, so that the connection is completed.
Claims (2)
