Description
Technical field
This utility model relates to wind pressure measurement field, is specifically related to a kind of house for the research of low rise buildings roof system wind pressure actual measurement.
Background technology
Device direction, existing wind load test room is fixed, and the frequency that high wind arrives is very low, considerably increases the difficulty of experiment, when high wind comes interim, it is impossible to according to the blast needed for wind direction flexibly capture assay, differ greatly with the ideal effect of test requirements document. The unfavorable wind load that test is required, the research of impact test may not necessarily be got.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of house for the research of low rise buildings roof system wind pressure actual measurement.
The purpose of this utility model is realized by such technical scheme, a kind of house for the research of low rise buildings roof system wind pressure actual measurement, including main house body, for measuring the wind pressure measurement system of main house body windward side blast, it is arranged at below main house body for carrying the base of main house body and upper cannelure, described base lower surface forms the lower cannelure corresponding with described upper cannelure, it is provided with some balls in lower cannelure, ball is pressed on lower cannelure by upper cannelure, the diameter of ball is less than or equal to upper, the groove width of lower cannelure, the diameter of ball is more than the distance of upper cannelure bottom land to lower cannelure bottom land, being provided with locating dowel on the chassis at described upper cannelure center, the base of main house body is provided with the through hole coordinated with locating dowel, the upper end of locating dowel is stretched in main house body after described through hole.
Further, the roof system that described main house body includes body of wall, be covered on body of wall and the lowering or hoisting gear for roof system is lifted, described lowering or hoisting gear includes support 1, commutation gearing speed-reducer 2, pedestal 3, long lead screw 4, adapter sleeve 5, flat thrust ball bearing 6, trapezoidal nut 8, bracing frame 9, clutch shaft bearing 18, sprocket wheel 19, limited block 22 and protection set 23; Be provided with trapezoidal nut 8 in the upper end of long lead screw 4, trapezoidal nut 8 is fixed with bracing frame 9, and bracing frame 9 is fixed on roof system; The lower end of described long lead screw 4 is connected with the port of commutation gearing speed-reducer 2 vertical direction, and the port of described commutation gearing speed-reducer 2 horizontal direction is connected with motor 17 and drive disk assembly;Described commutation gearing speed-reducer 2 is fixed on support 1, the housing of commutation gearing speed-reducer 2 upper end is fixed with bracing frame pedestal 3, installing, by flat thrust ball bearing 6, the set 5 that is located by connecting on bracing frame pedestal 3, described long lead screw 4 is connected by the port of adapter sleeve 5 with commutation gearing speed-reducer 2 vertical direction; Be provided with protection set 23 in the lower end of described long lead screw 4, protection set 23 is set on adapter sleeve 5, is convexly equipped with for protection set 23 is carried out spacing limited block 22 on the outer wall of adapter sleeve 5.
Further, described drive disk assembly is for including the first cross axle 7, jackshaft 12, universal joint fork the 13, second cross axle 14, reductor 16, motor 17 and power transmission shaft 20, the clutch end of motor 17 is connected with the power intake of reductor 16, the clutch end of reductor 16 is connected with power transmission shaft 20, power transmission shaft 20 is connected with the second cross axle 14, second cross axle 14 is connected with jackshaft 12 by universal joint fork 13, and jackshaft 12 is connected by the port of the first cross axle 7 with commutation gearing speed-reducer 2 horizontal direction.
Further, described wind pressure measurement system includes little differential pressure sensor, three way cock 27, pressure measurement probe 25, valve 31 and plenum chamber, described little differential pressure sensor includes static pressure and gathers port 29 and stagnation pressure collection port 28, stagnation pressure is gathered port and is connected to one end of three way cock by silica gel tube 26, the other two ends of three way cock are connected with pressure measurement probe and valve respectively, pressure measurement probe adopts external screw thread rustless steel hollow pipe, outwardly and inwardly it is connected with an internal coiling sleeve pipe respectively at roof system, valve is connected for getting rid of from the internal rainwater flow to of pressure measurement probe with drainage pipeline 30, described static pressure is gathered port and is connected with plenum chamber by silica gel tube, for measuring static pressure data, the afterbody of little differential pressure sensor is connected with harvester by cable, blast analogue signal is converted into digital signal by harvester, thus data acquisition work.
Owing to have employed technique scheme, this utility model has the advantage that
This utility model can make wind load test room adjustment direction flexibly, by the wind pressure sensor in test room, the wind pressure data to test room of the wind from different directions can be collected, substantially reduce the number test and consumed, save plenty of time and human and material resources, financial resources in a large number.
