Abstract

A kind of wood structure member sleeve for connection and connection method, it is an object of the invention to provide the branch sleeve between a kind of wood structure member, a kind of method that wood structure member is connected using the branch sleeve is provided simultaneously, the present invention is machined with the mechanism that can be embedded in wood structure member on the outer wall at sleeve two ends, sleeve is handled further through cooling device, therefore, when the connection for wood structure member, sleeve expands generation pressure because of temperature change, allow to be embedded in the mechanism insertion wood structure member in wood structure member, solve partial pressing's problem of stress concentration at bolt hole, and the ductility and compressive property at connecting node have large increase, improve the overall anti-seismic performance of timber buildings, it it also avoid the use of Chemical Felter, chemical noxious material is reduced to be detrimental to health.

Description

A kind of wood structure member sleeve for connection and connection method

Technical field

The invention belongs to technical field of civil engineering, and in particular to a kind of sleeve of wood structure member connection and connection side Method.

Background technology

Timber buildings are various informative, flexible layout, can be as needed, and the structure of building interior is easily made to change.Stress There is energy aspect, timber good resistance to compression, bending resistance and tensile property, particularly resistance to compression and bending resistance to have good plasticity, therefore Wooden frame structure structural system obtains many national applications in the whole world, with the continuous improvement of our people's living standard, Occurred modern wood frame house, villa and apartment in many areas of China, China realizing timber buildings industrialization, Standardization and supporting mounting technique, but China's timber buildings slower development are only limitted to some low layer commercial buildings and public built Build, but timber buildings system develops into the problem of domestic and foreign scholars research to multilayer and high-rise assembled architecture.

Current China timber structure factorial praluction is at the early-stage, on-site consolidation technology shortcoming, and especially wood structures are cut Size larger connecting node in face handles not perfect enough, the joint form being typically connected by screw bolts, and its compactness and toughness are good, Make simple, be common a kind of connected mode in timber structure, bolt by hole directly through wood structures, but bolt Gap is had surely with hole wall, this gap can cause discontinuity between bolt and hole wall, so as to can make locally to hold at bolt hole Compression is larger, and no matter timber used in wooden component is band or rift grain, can all be destroyed along the lines of timber, greatly Big reduction bolt connection bending rigidity.

Just because of disadvantage mentioned above, at present when timber structure is connected, first drilled in timber structure, hole is built into thin-wall sleeve Pipe, so as to reduce the gap between bolt and hole wall, but still to there is partial pressing's stress at bolt hole larger for such a technology Problem, while adding Chemical Felter during construction, is detrimental to health.

The content of the invention

It is an object of the invention to provide the branch sleeve between a kind of wood structure member, while providing one kind utilizes the connection The method of sleeve connection wood structure member, to solve stress concentration present in existing wood structure member attachment structure, lumber grain quilt The problem of destroying and be detrimental to health using Chemical Felter.

To achieve the above object, the present invention provides a kind of wood structure member sleeve for connection, it is characterised in that：Sleeve two ends Outer wall circumferential surface, which is provided with, can be embedded in the mechanism in wood structure member.

Described sleeve is divided into two at middle part as two sleeves, and the gap of one of sleeve is processed into ladder Formula, two sleeves are socketed and terminate in cascaded surface.

The described mechanism that can be embedded in wood structure member is some blades or cone.

Described blade or cone height are 2-3mm.

Described blade docks to form zigzag.

The present invention also provides a kind of wood structure member connection method, it is characterised in that comprise the following steps：

1）Punched according to wood structure member link node position；

2）Sleeve is placed in cooling device, the physical parameter of steel, determines cool time according to used in sleeve；

3) sleeve after cooling is placed in connected wood structure member, bolt is passed through into set when wood structure member returns to room temperature Cylinder simultaneously completes connection with nut fastening.

The length of described sleeve is not less than the length of connected wood structure member, in order to avoid timber structure is damaged when being connected Part.

It is an advantage of the invention that：

The present invention is machined with the mechanism that can be embedded in wood structure member on the outer wall at sleeve two ends, at cooling device Sleeve is managed, therefore, when the connection for wood structure member, sleeve expands generation pressure because of temperature change, allow to embedded wood In mechanism insertion wood structure member in structural member, partial pressing's problem of stress concentration at bolt hole, and connecting node are solved The ductility and compressive property at place have large increase, improve the overall anti-seismic performance of timber buildings, it also avoid chemistry viscous The use of agent is tied, chemical noxious material is reduced and is detrimental to health.

Brief description of the drawings

Fig. 1 is integral sleeve schematic diagram of the invention；

Fig. 2 is split type sleeve schematic diagram；

Fig. 3 is sleeve use state schematic diagram.

Embodiment

Reference picture 1, the specific embodiment of the invention is：Some blades 2 are provided with the outer wall at the two ends of integral sleeve 1, All blades dock to form zigzag.Also blade can be changed into pyramid, insertion is easier.

Reference picture 2, sleeve of the two ends with blade 2 is divided into two at middle part as I sleeves 3 and II sleeves 4, wherein II sets The gap of cylinder is processed into staged sleeve, and two sleeves are socketed and terminate in cascaded surface 5.

Reference picture 3, the connection method of wood structure member comprises the following steps：

1) wooden frame 6 is after prefabricated processing factory completes, and accurate measurement wood structure member needs position and the size of perforate；

2) sleeve 1 is placed in cooling device, the change of cooling device temperature is controlled by sleeve physical attribute itself, it is ensured that Volume Changes occur in cooling device for sleeve；

Etc. 3) when reaching the temperature requirement of setting, sleeve 1 is taken out through three wooden frames 6 and is placed in one, with ambient temperature liter Volume Changes can occur for height, sleeve, so that the blade 2 of sleeve both side ends position is completely embedded into the wooden frame at two ends, treat wood When beam returns to room temperature, bolt 7 is penetrated in wooden frame, and tightens nut 8, that is, completes connection.
