Abstract
The utility model discloses a full-area force-bearing concrete prefabricated split mounting type multi-purpose foundation for a tower machine, which comprises a combination body for concrete prefabricated pieces, a connecting and fastening device of the combination body, an anti-cutting piece and a fixing device for the tower machine, wherein the combination body is composed of a central piece, transition pieces, end pieces, a central balance weight piece and an edge anti-torsion balance weight piece. The utility model is characterized in that a convex beam which is perpendicular to the transition pieces and the end pieces is provided with a hole; a force distribution beam passes through the hole; the two ends of the force distribution beam are respectively pressed on the balance weight piece and the edge anti-torsion balance weight piece; shim plates are arranged between the force distribution beam, and the central balance weight piece and the edge anti-torsion balance weight piece, and the surfaces of the force distribution beam, the central balance weight piece and the edge anti-torsion balance weight piece are tightly abutted with each other to ensure that force is effectively transferred by the force distribution beam, thereby, the whole area of the foundation for the tower machine entirely bears force and the force bearing capability of the foundation for the tower machine is increased. The foundation of the same area can be used for a small-tonnage tower machine and can be suitable for a large-tonnage tower machine by adopting the technical scheme. The utility model has the advantages of simple, convenient and flexible operation.
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.That submits to before the inventor uses foundation for tower crane about the concrete precast assembly more (application number is: 2004200804052), 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, and dispose antitorque counterweight etc., it is perfect that concrete precast assembly foundation for tower crane has further been obtained, and prefabricated simple to operate with assembly unit, range of application is wider.But stress surface that should the basis only is about 3/5 of the basic gross area, its antitorque counterweights etc. are only as antitorque and counterweight, and do not give the function of its load-bearing, for large-tonnage tower machine, can only realize load-bearing by the middle transition part number of packages that increases the basis, so not only increase foundation cost, and increased construction cost.
Summary of the invention;
The technical problem to be solved in the present invention is: a kind of transition piece that does not need to increase the basis is provided, that is does not need to increase the area on basis, only need all to change the existing area on basis into lifting surface area, can realize same purpose.
The technical solution of the utility model is to realize like this, 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 by central part, transition piece, extremity piece, the antitorque counterweight of middle counterweight and edge constitutes, feature is perpendicular to transition piece, the protruding beam of extremity piece has the hole, the component beam passes from the hole, the two ends of component beam are pressed in respectively on middle counterweight and the antitorque counterweight in edge, at component beam and middle counterweight, be provided with backing plate between the antitorque counterweight in edge, their surface fits tightly together, to guarantee the component beam power is transmitted effectively.
Hole perpendicular to protruding beam can be square hole or circular hole, and this can decide according to the transverse shape of component beam, is square as its cross section, the Kong Zewei square hole, and vice versa; How much determining of hole by the weight capacity of component beam self.
Beneficial effect:
The utility model perforate on the protruding beam of transition piece, extremity piece, pass this hole by the component beam, with stressed middle counterweight and the antitorque counterweight in edge of passing to effectively of foundation for tower crane cross assembly, make the foundation for tower crane entire area all stressed, 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 schematic top plan view of the utility model rigid material component beam.
Fig. 2 is the A-A face sectional view of Fig. 1.
Fig. 3 has the sectional view in folk prescription hole for the B-B face of Fig. 1.
The specific embodiment:
As shown in Figure 1, how the stressed concrete precast assembly of gross area is a concrete precast assembly body with foundation for tower crane, as mentioned above, with the inventor about the technical scheme described in " the concrete precast assembly is used foundation for tower crane more ", connection fastener, shearing resistance part, the tower machine of foundation for tower crane are fixedly done pre-buried earlier and carried out prefabricated in many assembling bolts hole of usefulness, transition piece 2 wherein, extremity piece 3 also will prefabricatedly on protruding beam portal 6 by shown in Figure 3, and the inboard in hole 6 is provided with the lining of rigid material.After prefabricated component is made, be assembled into assembly as shown in Figure 1, component beam 7 is worn the protruding beam hole 6 of transition piece 2, hole 6 inwalls and component beam 7 outer walls match (as shown in Figure 2), the surface of counterweight 4 in the middle of the two ends of component beam 7 are pressed in, the two ends of passing the component beam in extremity piece 3 protruding beam holes 6 are pressed in the surface of the antitorque counterweight 5 in edge, the adjacent two ends of component beam 7 is in the center line both sides (as shown in Figure 1) of the antitorque counterweight 5 of middle counterweight 4 or edge, be provided with backing plate 8 (as Fig. 1 between the surface of the antitorque counterweight 5 of component beam and middle counterweight 4 and edge, shown in 2), the three is closely pressed together on together.Described backing plate 8 is selected rigid material in the present embodiment for use, and it is a rectangle, slightly is wider than the width of component beam, and backing plate 8 also can be used concrete prefabricated member.Described component beam 7 usefulness channel-section steels, i iron all can, what present embodiment adopted is channel-section steel.
The stressed concrete precast assembly 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 7.
