Abstract

The utility model relates to a low-cost earthquake-resistant reinforcing door frame for a purlin roof. The door frame comprises four parts, namely, a steel roof truss, steel pillars, gusset plates, and knee braces, wherein the steel roof truss and the steel pillars are welded together through the gusset plates; and one side of the knee braces are welded with the steel roof truss through the gusset plates, and the other sides are welded with the steel pillars. Grooves are formed on top chords of the steel roof truss at the gusset plates or formed by enclosing a plurality of orthogonal gusset plates. Due to the grooves, the load transmitted from a purlin can be efficiently transmitted to top chord node points, and the purlin cannot be divorced from the top chord node points in earthquake. The load transmitted from the purlin is firstly transmitted to the whole steel roof truss by the top-chord node points, and next transmitted to the steel pillars by the steel roof truss, and then transmitted to a foundation by the steel pillars, and finally transmitted by the foundation to a base. The purlin type low-cost earthquake-resistant reinforcing door frame efficiently changes the unreasonable stress state of the purlin roof and considerably overcomes the defects of a house with the purlin roof. A gable wall is changed from a bearing wall to an enclosure wall, so that the earthquake-resistant performance of a whole building is reinforced. Therefore, the casualties in vast rural areas in earthquake are lowered and the economic losses are reduced.

Description

Purlin low cost seismic hardening door frame is put on hard mountain
Technical field
The utility model relates to a kind of hard mountain and puts purlin earthquake-resistant building reinforcing door frame, belongs to intrinsic concrete structure reinforcement technical field.
Background technology
" 5.12 earthquake " that occurred in the Wenchuan, Sichuan in 2008 exposes incisively and vividly the anti-seismic performance of Chinese countryside local-style dwelling houses weakness.In our vast southwest, for example Yunnan Province also exists a large amount of wooden frame structures now.Load roof truss and roofing is all born by pin if this class house timber frame is complete, and body of wall only works the effect of going along with sb. to guard him.From the earthquake situation of repeatedly earthquake, this class house can be accomplished " wall fall the upright room of frame do not collapse " to show good seismic resistance when earthquake takes place.If timber frame is imperfect purlin directly is shelved on the gable, when promptly adopting hard mountain to put the purlin form, gable then is vertical supporting member, based on pressurized, in fact is in the eccentric compression state, and purlin bottom body of wall local compression.Therefore, the outer easily sudden strain of a muscle of body of wall is collapsed, interior sudden strain of a muscle is collapsed, roof truss bottom body of wall is easy to generate vertical straight joint.According to Pan Minghui; the paper that Miao's Noboru is delivered at world's earthquake engineering magazine " anti-seismic problem that China townlet and house, villages and small towns exist is seen in 6.2 grades of earthquakes from Dayao County, Yunnan Province " as can be known, the gable that the purlin house is put on hard mountain is higher, intensity is low, poor stability, easily interior the sudden strain of a muscle collapsed during earthquake, causes the roof system slump, cause resident family's death that is buried alive, personal casualty loss is quite heavy.Whole family's situation that none survived is not held the roof truss post and is adopted hard mountain to put the man of peasant household of purlin with regard to appearing in Dayao's 721 earthquakes.
Summary of the invention
The purpose of this utility model provides a kind of hard mountain and puts purlin low cost seismic hardening door frame.This door frame can improve the defective that the purlin house is put on hard mountain significantly, and gable is become enclosure wall by load bearing wall, thereby strengthens the anti-seismic performance of whole building.The casualties of vast rural area when reducing earthquake reduces economic loss.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model is made up of steel roof truss, steel column, gusset plate, angle brace four parts.Wherein, steel roof truss and steel column weld together by gusset plate, and angle brace welds with steel roof truss on one side mutually by gusset plate, and another side welds mutually with steel column.Winding up of steel roof truss has groove or surrounds a groove by several orthogonal gusset plates at the gusset plate place, what the load that these grooves transmit purlin can be passed to roof truss effectively winds up that purlin can not break away from the node that winds up when node and earthquake.The load that the node that winds up transmits purlin is passed to whole Pin steel roof truss, and steel roof truss is passed to steel column with load, and steel column is passed to ground with load, and last ground is passed to the basis with load.By such measure, change has taken place in the Path of Force Transfer of structure before and after reinforcing, and gable is by the enclosure wall of reinforcing after preceding load bearing wall becomes reinforcing.So just effectively changed the unreasonable force-bearing situation that purlin is put on hard mountain.
The beneficial effects of the utility model are: under the situation of less increase peasant economy burden, improve the defective that the purlin structure is put on hard mountain, thereby when reducing earthquake because the casualties that this defective causes, the reduction economic loss.
Below in conjunction with drawings and Examples the utility model is further specified, but structure of the present utility model is not limited to shown in the accompanying drawing.
Description of drawings
Fig. 1 is the front elevation view that purlin low cost seismic hardening door frame is put on hard mountain.
Fig. 2 is the side elevational view that purlin low cost seismic hardening steel column that door frame adopts and node thereof are put in hard mountain.
Fig. 3 is that hard mountain puts that purlin low cost seismic hardening steel roof truss that door frame adopts winds up and the vertical view of node.
The specific embodiment
Among Fig. 1 to Fig. 3, steel roof truss 1, steel column 2, gusset plate 3, angle brace 4.
By accompanying drawing as can be seen, this Scheme of Strengthening mainly is made up of four parts: steel roof truss 1, steel column 2, gusset plate 3, angle brace 4 four parts are formed.Steel roof truss 1 and steel column 2 weld together by gusset plate 3, and angle brace 4 welds with steel roof truss 1 on one side mutually by gusset plate 3, and another side welds mutually with steel column 2.Winding up of steel roof truss is fluted or surround a groove by several orthogonal gusset plates at the gusset plate place, and what the load that these grooves transmit purlin can be passed to roof truss effectively winds up that purlin can not break away from the node that winds up when node and earthquake.Because this Scheme of Strengthening is at the rural area, and rustic home is seldom considered modulus when building, and produce the Scheme of Strengthening that is fit to this family according to each tame real size when therefore it being reinforced, can be in this order when specifically implementing:
(1) measures the standard width of a room in an old-style house, depth, the floor height size of intending reinforcing the house, the concrete shape and the way thereof of observing out roofing;
(2) calculate dead load, live load, wind load, characteristic value of snowload according to the actual conditions of intending the reinforcing house, consider that the combination of above-mentioned standard value calculates each design load that node bore that winds up of institute's employing steel roof truss;
(3) design each member section of steel roof truss and the node size of intending employing according to each design load that node bore that winds up;
(4) design load that need bear by each steel column and Design of length thereof the various parameters that go out steel column;
(5) make designed steel roof truss and the steel column that comes out;
(6) steel column is installed;
(7) steel roof truss is installed;
(8) steel column and steel roof truss are welded;
(9) roof truss is winded up node firmly is connected with purlin;
(10) with jack with steel column jack-up, when the load of roofing is all born by steel roof truss and steel column, suspension column is fixed, install.
