Description
Technical field
The utility model relates to a kind of field of reinforcement of Steel Compression rod member, particularly relate to the steel bonding of a kind of local with the Steel Compression rod member reinforced, specifically being applicable to steel truss structure because of rod member buckle in compression causes Lack of support, rod member adopts local steel bonding to reinforce, and does not need to take off-load or supporting measure when reinforcing, can not weaken the Compressive Bearing Capacity in reinforcing face.
Background technology
After liberation, China has built a large amount of bent structure factory buildings, and bent structure is made up of post, roof truss, roof panel.These factory buildings are through the use of decades, and what have has met or exceeded design life, need to remove to rebuild.Some Enterprises is because of the reason of the aspects such as fund tightly maybe can not stop production, and unable dismounting is rebuild or stopped production and reconstructs.For ensureing production safety, must safety detection evaluation be carried out, after the structural element of strength deficiency is reinforced, national regulation, regulatory requirements must be met and just can continue to come into operation.
Generally steel roof truss is adopted when factory building span is large, safety detecting appraisal is carried out to this kind of steel roof truss, can find that some Steel Compression rod member of steel truss there will be because rod member buckle in compression causes the problem of Lack of support, make structural safety low, jeopardize the safety of structure.To the rod member of this strength deficiency, " steel structure strengthening technology specification " recommends to adopt the method strengthening bar cross section to reinforce, namely the mode of reinforcement of weld or snail bolt reinforcement by connection is adopted, by newly-increased steel rod elements be reinforced rod member and connect into entirety (see Fig. 1 and Fig. 2), improve anti-pressure ability and the Critical Load of Steel Compression rod member by increasing bar cross section.Implement to strengthen bar cross section reinforcing method under normal circumstances to have no problem, but under given conditions, adopt reinforcement of weld or snail bolt reinforcement by connection to there is following point:
1) adopt welding manner to reinforce: see Fig. 1, which needs welding on Steel Compression rod member to weld bar 5 to reinforce, and according to the regulation of " steel structure strengthening technology specification ", reinforcement of weld under load, requires the maximum nominal stress σ of steel beam column be reinforced
o maxbe in low-stress state, to guarantee construction safety.The design work condition classification of component is divided into four classes by this specification, requires I class | σ
o max|≤0.2f
y, II class | σ
o max|≤0.4f
y, III, IV class | σ
o max|≤0.55f
y, wherein f
yfor the standard value of steel yield strength.For the Steel Compression rod member of Lack of support, its maximum nominal stress σ
o maxsometimes up to 0.67f
yleft and right, does not meet above-mentioned low stress welding procedure conditional request, now must take the engineering measure such as off-load or supporting, and when requiring strengthening construction not affect plant produced, roof truss generally cannot unload or supporting.
2) snail bolt reinforcement by connection is adopted: see Fig. 2, this kind of mode needs to hole on the Steel Compression rod member be reinforced, and will certainly reduce the cross-sectional area of boring sites in curing, weaken the Compressive Bearing Capacity in this cross section, affect consolidation effect.When Steel Compression bar cross section intensity affluence amount hour, this cross-sectional strength after boring, is easily caused not meet code requirement; When there being multiple boring bolt 6 to connect, hole in scene, accurately positioning difficulty is large.
Summary of the invention
The purpose of this utility model overcomes needing of existing in prior art to take off-load or supporting measure, easily weaken the defect and the problem that are reinforced face Compressive Bearing Capacity, provide a kind of and do not need to take off-load or supporting measure, can not weaken be reinforced face Compressive Bearing Capacity local steel bonding with the Steel Compression rod member reinforced.
