Anti-side and Self-resetting performance study technical field.
Background technique
Heavy timber construction refers to the structural system using large scale wood component as main supporting member.Outside heavy timber construction
The wood characteristics of dew make it have unique construction aesthetic perception.It is heavy other than possessing the advantage of light-duty wooden low-carbon, environmental protection
Timber structure due to scantling it is larger and the features such as show more excellent fire resistance and endurance quality.But such knot
The anti-side rigidity and bearing capacity of structure system are limited, it usually needs and buckling restrained brace is used in conjunction with.
In the prior art, steel wood buckling restrained brace is one of common anti-side element in heavy timber construction, has consumption
The advantages that energy ability is low, convenient for structure installation.But this supporting form still has several drawbacks:
One, the support hardly has runback bit function: when the behavior of compression overall collapse or tension occurs in embedded steel core plate
After surrender, support would generally generate apparent irrecoverable deformation.
Two, the wooden component only serves the effect for constraining embedded core plate, and rift grain direction does not almost stress, thus the utilization rate of intensity
It is limited.
Three, since the elasticity modulus of steel is apparently higher than timber, thus such support and the matching of timber structure still need
It further to study.
In view of the above several points, it is necessary to take technical measures promoted the Self-resetting performance of buckling restrained brace, bearing capacity with
And the matching with timber structure.
Summary of the invention
Technical problem to be solved by the present invention lies in a kind of timber structure buckling restrained brace is provided, can make the wooden component with
Core material participates in stress jointly, promotes the bearing capacity of buckling restrained brace.
To solve the above-mentioned problems, The technical solution adopted by the invention is as follows:
A kind of timber structure buckling restrained brace, it is characterised in that: including the first wooden component, the second wooden component, shape note
Recall alloy core material, several marmem screw rods and anchor,
The described first wooden component and the second wooden component respectively have planar side,
Two wooden components are affixed merging and open up along timber vertical line direction in binding face and be collectively formed one in plane side to be led to
Slot, the through slot match with the shape of the marmem core material, and marmem core material is embedded in through slot, shape
The both ends of shape memory alloys core material are stretched out outside two wooden components,
The marmem screw rod runs through two wooden components, marmem spiral shell along perpendicular to timber vertical line direction
Bar is fixed after tension tool tensioning by both ends of the anchor to marmem screw rod.
Further, the marmem core material is linear type core plate or bar.
Further, the described first wooden component respectively accounts for the one of through slot depth in the groove depth for being bonded position with the second wooden component
Half.
Further, the height of the through slot is the one third of two wooden component binding face height.
The present invention also provides the production methods of above-mentioned timber structure buckling restrained brace, comprising the following steps:
S1, it slots respectively along opposite side of the timber vertical line direction to the first wooden component and the second wooden component, then by two
The wooden component fits together；
S2, marmem core material is placed in the through slot being collectively formed between two wooden components, makes shape memory
The both ends of alloy core material are stretched out outside two wooden components；
S3, according to the wooden sectional dimension of members, drill in two wooden components perpendicular to timber vertical line direction, then again two
Marmem screw rod is penetrated in a component；
S4, tensioning is carried out to marmem screw rod using tension tool, then using anchor to shape memory
The both ends of alloy screw are fixed.
Further, the marmem core material is linear type core plate or bar.
Further, the described first wooden component respectively accounts for the one of through slot depth in the groove depth for being bonded position with the second wooden component
Half.
The working principle of the invention is that the ultimate tensile intensity of marmem is much higher than timber, thus applies and answer in advance
Power can more effectively utilize the strength of materials of marmem screw rod.Marmem screw rod can be in two wood after tensioning
Extruding force is generated on the band direction of component, to guarantee the close contact of the wooden component Yu marmem core material.By rubbing
Wiping effect makes the wooden component participate in stress, makes full use of the advantage that strength of structural timber parallel to grain is high, promotes the bearing capacity of buckling restrained brace.
Compared with prior art, the beneficial effects of the present invention are:
1, compared with steel, the elasticity modulus of marmem and timber more closely, thus buckling of the invention about
Bundle branch support is more preferable with the matching of timber structure.Under screw rod prestressing force and marmem collective effect, the Self-resetting of support
Performance significantly improves.
2, prestressed application can guarantee that two wooden components are formed with embedded core material and effectively contact, and make wood by rubbing action
Component participates in stress, to promote the bearing capacity of support.
3, timber structure buckling restrained brace of the invention is easy to make, convenient for constructing and promoting in engineering.
Detailed description of the invention
Fig. 1 is the main view of one embodiment of the present invention.
Fig. 2 is the top view of one embodiment of the present invention.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.According to following explanation, originally
The purposes, technical schemes and advantages of invention will be apparent from.It should be noted that described embodiment is of the invention preferred
Embodiment, instead of all the embodiments.
