Abstract
The utility model discloses a gross area receiving stress concrete prefabricated sectioned multiple use tower engine foundation, including a combination of concrete precast products, a connecting and tightening device for the combination, shearing resistant piece and a tower engine fixing mechanism. The combination is formed by a centerpiece, a transition piece, a tail piece, a middle counterweight piece, and a fringe torsion resistant counterweight piece. The combination also includes a component of force girder on its top, and a back-up provided between the component of force girder and the surface of the combination. The component of force girder is symmetrically mounted at two sides of the cam girder of the transition piece and of the tail piece; the component of force girder, the transition piece, and the tail piece are connected via linkage unit. The utility model need not to provide a hole on the cam girder of the transition piece and of the tail piece to pass the component of force girder; it only need to provide a connecting hole to connect bolt or pass the steel strand. Because the diameter of the connecting hole is very small, it will not affect the bearing stress ability of the cam. The utility model greatly increases the weight bearing capacity of the tower engine fundament.
Description
Technical field:
The utility model relates to construction implement and installs and fixes the concrete basis, relates to the concrete precast assembly particularly and uses foundation for tower crane more.
Background technology:
At present, in building operations, the concrete precast assembly is used foundation for tower crane more, to have a site operation cycle short because of it, and demolition, installation, fortune are convenient and swift, non-environmental-pollution, the No Assets waste, and can improve the utilization ratio of tower machine and the use cost of saving the tower machine, and generally be subjected to attention in the industry, applied in many areas.The inventor had submitted the many parts of patent applications of using foundation for tower crane about the concrete precast assembly to over the past two years, prior art further improvement and innovation have been done, as improvement to the coupling arrangement of foundation for tower crane assembly, design to the fixing position, many assembling bolts hole of tower machine, dispose antitorque counterweight, and to improvement of basic stress situation etc., make concrete precast assembly foundation for tower crane further obtain perfect, especially to the improvement of basic stress situation, improved the lifting surface area (that is weight capacity) of foundation for tower crane greatly, made its range of application wider.But this technical scheme when improving its lifting surface area, inevitably influences the protruding beam stress ability of composite member owing to perforate on the protruding beam of composite member is bigger.
Summary of the invention;
The technical problems to be solved in the utility model is: provide the stressed concrete precast assembly of a kind of gross area to use foundation for tower crane more, when effectively improving basic stress area (that is weight capacity), do not influence protruding beam stress ability.
The utility model is achieved through the following technical solutions: the stressed concrete precast assembly of a kind of gross area is used foundation for tower crane more, the assembly that comprises concrete prefabricated member, the connection fastener of assembly, shearing resistance part and tower machine fastening devices, described assembly is made of central part, transition piece, extremity piece, the antitorque counterweight of middle counterweight and edge, described assembly also comprises the component beam that is provided with on it, and set backing plate between component beam and the assembly surface; Described component beam is symmetricly set in the protruding beam both sides of transition piece, extremity piece, is connected by linkage between component beam and transition piece, the extremity piece.
Beneficial effect:
The utility model need not have the hole of passing for the component beam on the protruding beam of transition piece, extremity piece, get final product and only need leave the connecting hole that supplies connecting bolt or steel hinge line to pass, because this connecting hole diameter is very little, protruding beam stress ability is had no effect.The utility model can make the foundation for tower crane entire area stressed the stressed middle counterweight and the antitorque counterweight in edge of passing to effectively of foundation for tower crane assembly, has improved the weight capacity of foundation for tower crane greatly.The basis of same area, both can be used for little tonnage tower machine, also can adopt the technical program to be adapted to large-tonnage tower machine, thereby in cost that does not increase the large-tonnage foundation for tower crane and construction cost, the utility model also have simple, convenient advantage flexibly.
Description of drawings:
Fig. 1 is the utility model schematic top plan view.
Fig. 2 is the A-A face sectional view of Fig. 1.
The specific embodiment:
Embodiment one:
As shown in Figure 1, how the stressed concrete precast assembly of a kind of gross area is a concrete precast assembly body with foundation for tower crane, and integral body is anistree windmill shape, and component beam 6 is symmetricly set in transition piece 2, extremity piece 3 protruding beam both sides; Be arranged at termination, component beam 6 two ends on the transition piece 2 be pressed in the middle of the surface of counterweight 4, be arranged at the surface that termination, component beam 6 two ends on the extremity piece 3 is pressed in the antitorque counterweight 5 in edge.The center line both sides of counterweight 4 or the antitorque counterweight 5 in edge in the middle of component beam 6 adjacent terminations, two ends are positioned at.Component beam 6 and middle counterweight 4 or and the surface of the antitorque counterweight 5 in edge between be provided with backing plate 7, the three is closely pressed together on together.
As shown in Figure 2, be respectively arranged with connecting hole 8, be parallel to component beam 6 axis and be provided with connecting hole 9 perpendicular to the protruding beam of transition piece 2, extremity piece 3.Bolt passes connecting hole 8, connecting hole 9, with nut transition piece 2 or extremity piece 3 is connected and fixed on component beam 6.
Embodiment two:
As shown in Figure 2, be respectively arranged with connecting hole 8, be parallel to component beam 6 axis and be provided with connecting hole 9 perpendicular to the protruding beam of transition piece 2, extremity piece 3.Steel hinge line passes connecting hole 8, connecting hole 9, with anchor clamp transition piece 2 or extremity piece 3 is connected and fixed on (diagram is not provided) with component beam 6.All the other are implemented as embodiment one.
The stressed concrete precast assembly of a kind of gross area is as shown in Figure 1 used foundation for tower crane more, and its stress-bearing capability improves more than 30% than the foundation for tower crane that does not add component beam 6.
