Abstract
The utility model provides a kind of blast cutting joist steel upright, comprising: wing plate (1) and web (2), and I-shaped two side plate is wing plate (1), and I-shaped intermediate plate is web (2); Web (2) is provided with web opening (3), wing plate (1) is provided with cutting hookup wire (5), cutting hookup wire (5) and wing plate (1) junction, both sides are provided with burst disk otch (4).The utility model successfully solves the problem that steel construction directional explosion is removed, and reduces the risk and cost of high-rise working during manual demolition, and the safety of removing for steel construction provides guarantee, greatly can shorten the construction period simultaneously.
Description
Technical field
The utility model relates to explosion field, particularly relates to a kind of blast cutting joist steel upright.
Background technology
It is the comprehensive application technology of an and building collapsing theory theoretical in conjunction with blast cutting that steel construction blast cutting is removed, and records at present, description there are no pertinent literature.In prior art, Explosive Cutting Technique and structure demolition demolition technique two kinds of technology.These two technology existing all have respective limitation, can not solve separately the needs of steel work directional explosion cutting disassembling.As Explosive Cutting Technique only processes the cutting resolution problem of sheet metal at present, such as shipwreck deck cutting disassembling etc., and structure demolition demolition technique is also only limitted to the demolition blasting of reinforced concrete structure building at present.There are no the case that the two combines, also have no description and how the technical writing case studies etc. that jet cutter could realize steel building blasting cut is installed.
Summary of the invention
The purpose of this utility model is to provide a kind of blast cutting joist steel upright, and joist steel upright naturally can depart from original position and form blasting cut after being blown up.
In order to solve the problems of the technologies described above, the utility model provides a kind of blast cutting joist steel upright to be achieved in that
A kind of blast cutting joist steel upright, comprising: wing plate 1 and web 2, I-shaped two side plate is wing plate 1, and I-shaped intermediate plate is web 2; Web 2 is provided with web opening 3, wing plates on two sides 1 is provided with cutting hookup wire 5, cutting hookup wire 5 is provided with burst disk otch 4 with junction, wing plate 1 both sides.
Optionally, the angle 35 of described cutting hookup wire 5 and wing plate 1 level
0≤ α≤45
0.
Optionally, described web opening 3 has two, and parallel with the both sides up and down of web 2, two ends are crossing with wing plate 1.
Optionally, described cutting hookup wire 5 respectively has one in wing plate (1) both sides.
The blast cutting joist steel upright that the utility model provides, web is provided with web opening, wing plate is arranged cutting hookup wire, at cutting hookup wire as the calibration line installing cutter, cutter and junction, wing plate both sides arrange burst disk otch, ensure that naturally can depart from original position after joist steel upright is blown up forms blasting cut.The utility model successfully solves the problem that steel construction directional explosion is removed, and reduces the risk and cost of high-rise working during manual demolition, and the safety of removing for steel construction provides guarantee, greatly can shorten the construction period simultaneously.
Further, the blast cutting joist steel upright that the utility model provides, the angle 35 of described cutting hookup wire and wing plate
0≤ α≤45
0, determine through lot of experiments, when cut angle α is within the scope of 35 ° to 45 °, the effect of linear incision is best.
Accompanying drawing explanation
Fig. 1 is the blast cutting joist steel upright front view that the utility model provides;
Fig. 2 is the blast cutting joist steel upright right view that the utility model provides;
Fig. 3 is the blast cutting joist steel upright top view that the utility model provides.
Wherein, 1-wing plate, 2-web, 3-web opening, 4-burst disk otch, 5-cuts hookup wire.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, Figure 2 and Figure 3, the blast cutting joist steel upright that the utility model provides, comprising: wing plate 1 and web 2, and I-shaped two side plate is wing plate 1, and I-shaped intermediate plate is web 2; Web 2 is provided with web opening 3, wing plates on two sides 1 is provided with cutting hookup wire 5, cutting hookup wire 5 is provided with burst disk otch 4 with junction, wing plate 1 both sides.
For guaranteeing cutting effect, the angle 35 of described cutting hookup wire 5 and wing plate 1
0≤ α≤45
0.
For guaranteeing that joist steel upright naturally departs from original position and forms blasting cut, described web opening 3 has two, and parallel with the both sides up and down of web 2, two ends are crossing with wing plate 1.
For guaranteeing that joist steel upright naturally departs from original position and forms blasting cut, described cutting hookup wire 5 respectively has one in wing plate (1) both sides.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
