Abstract
The utility model discloses an anti-slipping anchorage device for a spliced tower crane foundation. The anti-slipping anchorage device comprises an anchor ring and a clamping piece in the anchor ring. Threads are arranged on the periphery of a clamping end of the anchor ring; matched threads are arranged on an inner peripheral surface of a clamping cap; the clamping cap is in threaded connection with the clamping end of the anchor ring; and a connecting object piercing hole is formed in the top of the clamping cap. The anti-slipping anchorage device has a good anti-slipping effect, the structure of the conventional anchorage device is not required to be changed, only the threads are required to be arranged on the clamping end of the anchor ring, and the clamping cap is connected with the clamping end of the anchor ring to tightly push the clamping piece. The anti-slipping anchorage device is simple in manufacture and low in cost. A sealing ring is arranged on the inner periphery of the connecting object piercing hole in the top of the clamping cap, so that rainwater can be prevented from entering the anchorage device, and an anti-corrosion effect is good.
Description
Technical field
The utility model relates to the basis that building machinery installs and fixes, and is specifically related to the connector of pin-connected panel foundation for tower crane.
Background technology
Concrete precast assembly foundation for tower crane, 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 and the use cost of practicing thrift the tower machine of tower machine, and generally receive an acclaim, applied preferably.In the last few years; The applicant has proposed a series of patent applications and has obtained the authorization; Concrete precast assembly foundation for tower crane has been done further to improve, and for example the patent No. is: 200620142420.4, and name is called " the antiskid fastener that big-and-middle-sized concrete precast assembly is used foundation for tower crane more "; The further improvement of making to the fastener of the steel strand that connect each prefabricated component exactly; When load was in the negative stress state, fastener is slippage very easily for fastener of the prior art (anchor slab anchor clamps), and made fixation loosening.The structure of disclosed antiskid fastener in the above-mentioned patent; Like second page in manual said " the antiskid fastener comprises ground tackle, intermediate plate, and characteristics are that ground tackle has plush copper, and the plush copper inboard is provided with screw thread; push-tight nut arranged outside has the screw thread that matches; push-tight nut one end pushes up with intermediate plate mutually, and behind the push-tight nut screwing clamping, the intermediate plate in the ground tackle can not skid off because of the negative stress effect ".Know that from above-mentioned this " antiskid fastener " exists following defective: the one, processing and fabricating comparatively complicated (need special-purpose mould, also need) in the inner peripheral surface tapping; The 2nd, environment for use is had relatively high expectations, for example can not long period of soaking in water or in the earth, otherwise corrosion easily, the safe handling of tower machine is threatened.
Summary of the invention
The technical problem that the utility model will solve provides a kind of antiskid ground tackle that is used for the pin-connected panel foundation for tower crane, can overcome the defective that prior art exists.
The utility model is realized through following technical scheme:
The antiskid ground tackle that is used for the pin-connected panel foundation for tower crane comprises the intermediate plate in anchor ring, the anchor ring, and said anchor ring pinching end periphery is provided with screw thread, and the clamping cap inner peripheral surface is provided with the screw thread that is complementary, and clamping cap is threadedly connected to the anchor ring pinching end; Said clamping cap top is provided with attachment and passes the hole.
The further improvement project of the utility model is to be provided with elastic between clamping cap top and the intermediate plate end.Said elastic is a spring, or is elastomeric pad.
The utility model further improvement project is, said attachment passes hole and the setting of anchor ring concentric, said hole interior week be provided with sealing ring.
The utility model compared with prior art has following obvious advantage:
One, the utility model not only has antiskid effect preferably, and need not change the structure of existing ground tackle, only needs in anchor ring pinching end periphery screw thread is set, and is connected in the anchor ring pinching end with clamping cap and intermediate plate is held out against get final product, makes simply, cost is low.
Two, the attachment of the utility model at the clamping cap top passes that week is provided with sealing ring in the hole, can prevent effectively that rainwater from getting into, and anti-corrosion is effective.
Description of drawings
Fig. 1 is the utility model cross-sectional schematic.
The specific embodiment
As shown in Figure 1, be used for the antiskid ground tackle of pin-connected panel foundation for tower crane, comprise the intermediate plate 2 in anchor ring 1, the anchor ring 1, said anchor ring 1 pinching end periphery is provided with screw thread 3, and clamping cap 4 inner peripheral surfaces are provided with the screw thread that is complementary, and clamping cap 4 is threadedly connected to anchor ring 1 pinching end.
Still as shown in Figure 1, be provided with elastic 5 between clamping cap 4 tops and intermediate plate 2 ends, said in the present embodiment elastic 5 is selected elastomeric pad (like rubber sheet gasket) for use.
Still as shown in Figure 1, the clamping cap top is provided with attachment 6 and passes the hole, saidly passes hole and the setting of anchor ring concentric, the hole be provided with sealing ring 7 interior week.In the present embodiment, said attachment 6 which is provided with ground tackle after from the hole of prefabricated component 8, passing.
