Abstract
The utility model discloses a quick-install truss and a quick-install house using the quick-install truss. Upper chord members, a lower chord member and a roof web member in the quick-install truss are B-type steel profiles; a ridge web member is a B-type steel profile or a tubular profile; the lower ends of the two upper chord members are fixedly connected with the end part of the lower chord member through a lower chord member connecting plate respectively; two ends of the roof web member are fixedly connected with the upper chord members and the lower chord member respectively; one end of the ridge web member is fixedly connected between two opposite ends of the two upper chord members; the other end is fixedly connected to the lower chord member. The bending resistance of the overall truss is improved because of the characteristic that the B-type steel profile is more excellent than the C-type steel profile in inertia moment in the using process; the effect of saving the cost is achieved by adopting a single B-type steel profile, so that the construction cost of the overall truss is reduced.

The specific embodiment
The embodiment 1 of assembled house of the present utility model: extremely shown in Figure 7 as Fig. 1, this assembled house comprises the left and right body of wall 1,2 and the fast-assembling truss of bridge joint between left and right body of wall 1,2 of relative distribution, described right body of wall 2 has the column 21 of the steel that extends up and down, and the upper end of column 21 is in the right side of fast-assembling truss; Described fast-assembling truss comprises upper chord 3, lower chord 4, roofing web member 5 and the ridge web member of being made by single Type B steel profile 6, described upper chord 3 has two and surround the body frame body that is isosceles triangle with lower chord 4, roofing web member 5 bridge joints between upper and lower chord member 4 in the sloped roof position, upright middle position, the upper end that is located at lower chord 4, the lower end of ridge web member 6 is under the upper end of two upper chords 3 so that ridge web member 6 that the position is set is corresponding with the ridge position of assembled house.The two ends of roofing web member 5 are fixed on the upper and lower chord member 3,4 by first and second trip bolt 51,52 respectively.Between the lower end of the two ends of lower chord 4 and two upper chords 3 respectively bridge joint lower chord junction plate 7 is arranged, and lower chord junction plate 7 be equiped with on, lower chord 3,4 the 3rd fixedly connected trip bolts 71, so that on, lower chord 3,4 are fixed together by lower chord junction plate 7 and the 3rd trip bolt 71, and align at above-below direction with the end of the lower chord 4 of corresponding position in the lower end of upper chord 3, the right-hand member that is in the lower chord junction plate 7 on right side stretches out from the right side of lower chord 4, and extension is fixed on by the 8th trip bolt 72 on the body of wall junction plate 22 fixing on the left surface of column 21 upper ends; Set up on the upper surface of left body of wall 1 in the left side of lower chord 4.Fixedly there is upwardly extending upper chord junction plate 8 upper end of ridge web member 6 by the 4th trip bolt 61, and being equiped with the 5th trip bolt 81 at upper chord junction plate 8, upper chord junction plate 8 is fixed together by the upper end of the 5th trip bolt 81 and two upper chords 3; The lower end of ridge web member 6 is fixed on the central position of lower chord 4 by the 6th trip bolt 62.
The assembled house of present embodiment is aspect production technology: the Type B steel profile is selected the thin-wall section that is made through the disposable cold roll forming of cold-bending forming machine by galvanized steel plain sheet for use, can produce according to the designing requirement scale, can waste material;
Aspect energy-conserving and environment-protective: the Type B steel profile still all is the type of attachment that adopts trip bolt in the middle of the process of member no matter be on production technology, and the trip bolt wing plate selects self-tapping screw for use, so just can not produce dusty gas.
Aspect cross section property: well-known, in the steel work selection, as primary structure member, first-selected all is the good steel of self cross section property, such as doing relatively with angle steel, channel-section steel with square steel pipe, no matter be for large-scale factory building, or small-sized construction steel structure house, structure etc.The material first-selection or the square steel pipe that are used for main bearing member, reason be exactly in the middle of the square steel pipe cross section property second moment of area, and resistance moment to be far superior to angle steel and channel-section steel.It is the light-gauge steel section material of a closure that forms through multiple tracks bending rear catch that the Type B steel profile adopts the cross section.And the cross-sectional configuration of C shaped steel section bar is simple, and less than the Type B steel, intensity is relatively poor far away for its second moment of area and resistance moment.
Aspect application: the special type in the cross section of Type B steel profile is preponderated, it not only can be used as industrial premises roof purline and metope purlin, can also do the roofing truss in large span factory building, warehouse, single span and multispan can realize and play fine stressed effect, in addition outdoor, indoor members such as stair.Main is that the Type B steel are mainly used in the central roofing system of civilian construction, no matter be many pitched roofs of simple double-slope roof, complexity.The Type B steel can be processed into the roofing truss that needs, and more are applicable to the structural system of multispan.
In result of use and save aspect material, the cost: the cross section property of Type B steel profile is good, and its used raw-material galvanized steel plain sheet general thickness is between 0.6mm ~ 1mm.The roofing truss that is processed into is very light, common civilian construction, and the roofing truss of single limb just can reach its requirement of strength.A same truss structure weighs 2 ~ 3 times with the C shaped steel truss than working it out with the Type B steel profile that this is worked it out the new year, if the structure of large span also will weigh a lot.Not only wasted material also increased a large amount of artificial, and processing and fabricating, install all very inconvenient, thereby increased cost.The outward appearance of Type B steel profile is good-looking than C shaped steel in addition, can play the effect of decoration.
