The feature of cement bunker top of the present invention Elements of Space Grid Truss braced structures is also: the far-end of hanging oneself from a beam at described shaped steel arranges hanging ring screw, and described pull bar is connected with hanging ring screw by turnbuckle.
The feature of the construction method of cement bunker top of the present invention Elements of Space Grid Truss braced structures is carried out as follows:
Step 1: on the round apical ring beam of described clinker warehouse wall, point to be on the inside wall of clinker warehouse wall and lateral wall and to be symmetrical arranged shaped steel supporting leg; On described round apical ring beam, utilize and described shaped steel supporting leg is fixedly installed in cantilevered fashion shaped steel overarm, described shaped steel overarm overhangs towards the outside of clinker warehouse wall in level;
Step 2: be fixedly installed each carrier setting bolt ball on described round apical ring beam, is fixedly mounted on described carrier setting bolt ball in upright column, on the top of described column, fixed installation first floor winds up spiral ball; Wherein, carrier setting bolt ball corresponds to shaped steel supporting leg position and is in the center of round apical ring beam, and wind up spiral ball and described carrier setting bolt ball of described column and first floor is being on same vertical position;
Step 3: the adjustable pull bar of connecting length between string spiral ball and the shaped steel far-end of hanging oneself from a beam on the first layer; Wind up spiral ball as bottom supporting unit using pull bar, carrier setting bolt ball, column and first floor, utilize rod member and by carrier setting bolt ball and the first floor spiral ball that winds up, each bottom supporting unit be evenly distributed on the round apical ring beam of clinker warehouse wall carried out complete cycle connection, forming rack reference circle;
Step 4: the holding state keeping each bottom supporting unit, rack reference circle successively upwards completes clinker warehouse Elements of Space Grid Truss shaping across construction.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention is based on the round apical ring beam of wall of cement bunker, and the assembly working environment of its rack reference circle is greatly improved, and construction quality and workman's personal safety are protected.
2, in the present invention, Tiebar structure is light, detachable, and it is easy to assembly, technique is simple, easy to operate, and only need a crane to complete construction, the adjustable of pull bar length effectively can guarantee construction precision.
3, the deadweight active balance gravity of bracing frame of pull bar and shaped steel overarm in the present invention, the center of gravity of the structural system at more than clinker warehouse wall top is overlapped with clinker warehouse top center substantially, greatly reduce eccentric moment, on shaped steel supporting leg, upper group power of expansion bolt is relatively little, be conducive to the stable of whole system, thus guarantee construction safety.
4, the present invention adopts pull bar can realize the stable of bracing frame, and auxiliary construction material is only 1/4th of high-altitude stent support formula construction method material therefor, and mounting cost be only its 1/5th, therefore its economic benefit is clearly.
5, in the present invention, pull bar is reusable, can save temporary lining Master Cost further, and the construction period is relatively short simultaneously, and the total investment of engineering of cement bunker significantly reduces.
