Accompanying drawing 2 is removable support bridge elevations of the utility model embodiment 1.
Among the figure: 1, pontic, 2, the support portion, 3, hold-doun nut, but 4 adjusting screw(rod)s, 5, disciform screw hole, 6, level controlling board, 7, the absolute altitude regulating nut, 8, lock nut.
The specific embodiment
Embodiment 1:
As shown in Figure 1 and Figure 2, present embodiment is the removable support bridge that uses in a kind of efficient large area concrete floor construction, and this support is in carrying out concrete construction, be arranged on ground, be used for the back-up roller axis rail, after construction is finished, can take out and continue to use.
The present embodiment supporting bridge comprises pontic 1, support portion 2 and absolute altitude adjusting portion; Pontic 1 is arranged on the support portion 2; Pontic (1) is one section reinforcing bar, at each hold-doun nut 3 of two ends welding as pontic 1 reinforcing bar; Support portion 2 is for being welded on two " splay configuration " supporting leg reinforcing bars as the bottom of pontic 1 reinforcing bar.The absolute altitude adjusting portion is arranged on the pontic .1 reinforcing bar, but but comprise pontic 1 reinforcing bar each hold-doun nut 3 of two ends welding, in each hold-doun nut 3, respectively mesh an adjusting screw(rod) 4, respectively mesh an absolute altitude regulating nut 7 and level controlling board 6 above the hold-doun nut 3 on the adjusting screw(rod) 4 at each; Level controlling board 6 comprises two blocks of orthogonal sheet materials, but wherein the sheet material of level passes adjusting screw(rod) 4 by described absolute altitude regulating nut 7 supports, and the sheet material top that number horizontal vertical makes progress is the absolute altitude line.
In the present embodiment, level controlling board 6 is one section angle steel, but on angle steel according to the relative position relation of adjusting screw(rod) 4, be provided with two disciform screw holes 5 and be called absolute altitude control angle steel.But on adjusting screw(rod) 4, also be engaged with lock nut 8.
The product of present embodiment can be according to the equipment of job site, the making of gathering materials on the spot, and process is as follows:
Select the bridge joint reinforcing bar of the about 150mm of length, a diameter 14mm as pontic 1, " splay configuration " supporting leg reinforcing bar at four diameter 10mm of bottom welding of bridge joint reinforcing bar, respectively weld a hold-doun nut 3 at bridge joint reinforcing bar two ends, but wear separately an adjusting screw(rod) 4 supporting, the about 120mm of length in two hold-doun nuts 3, but about the silk mouthful width 2mm of adjusting screw(rod) 4 and hold-doun nut 3, be beneficial to turning of concrete cleaning and screw rod in the concrete construction.But more in addition according to the relative position relation of adjusting screw(rod) 4; adopt with ∟ 30 * 30 * 3 specifications, the angle steel of the about 200mm of length, but the relative position relation according to adjusting screw(rod) 4, two disciform screw holes 5 of processing and fabricating, being made into absolute altitude control angle steel is level controlling board 6, before but absolute altitude control angle steel penetrates adjusting screw(rod) 4, but the absolute altitude regulating nut 7 of on two adjusting screw(rod)s 4, screwing on respectively first, but penetrate in the adjusting screw(rod) 4 absolute altitude being controlled angle steel, but be screwed into lock nut 8 on absolute altitude control angle steel top along adjusting screw(rod) 4 at last, the removable support bridge is just made complete like this.
The method of removable support bridge is installed, at first by measuring accurately unwrapping wire, go out several some positions that spacing is 1400mm in ground survey, hammer into the steel nail more than the diameter 3mm in a position, bind the drawknot iron wire of 16# specification on the steel nail, the bridge joint reinforcing bar that iron wire and absolute altitude control reinforcement bar support is built bridge linking together tightly built bridge mobile to prevent absolute altitude control reinforcement bar support.The installation that absolute altitude control reinforcement bar support is built bridge should strictly be installed by measuring the control line position, can become a straight line after guaranteeing to install.
Until absolute altitude control reinforcement bar support build bridge install and fix complete after, absolute altitude how to measure, adjust absolute altitude control angle steel is a very important step, by near suitable position building bridge at absolute altitude control reinforcement bar support a laser-measured height instrument is set, measure the absolute altitude value of absolute altitude control angle steel face by overcasting staff, contrast elevation design value, but adjusting screw(rod) and absolute altitude regulating nut by the portable absolute altitude control of turn reinforcement bar support is built bridge reach the design elevation value so that absolute altitude is controlled the absolute altitude at angle steel top.
In work progress, adopt the supporting bridge of present embodiment, the concrete absolute altitude levelling control that the concrete floor that is applicable to 100mm ~ 600mm thickness is once constructed and survived, overcome the deficiency of tradition " mortar ash cake " control technology, under the safe prerequisite of ensuring the quality of products, simplify construction technology process, reduced cost, accelerated speed of application, improve the planeness control quality of concrete surface, had simple to operate, the characteristics such as mass effect obvious, environmental protection and energy saving.This job practices obtained the certainly consistent of construction workman and praised highly, and the aspects such as job practices, speed of application, construction quality have all obtained the consistent favorable comment of Construction unit, supervisor.
