Abstract
The invention discloses a cantilever frame anchoring element. A bolt in an existing cantilever frame anchoring element is too long, and an anchoring plate is prone to fall. The cantilever frame anchoring element comprises a concrete plate, the anchoring plate and a pressing plate, wherein the anchoring plate is arranged at the bottom of the concrete plate, the pressing plate tightly presses a steel beam between the pressing plate and the surface of the concrete plate, an adjusting rod is disposed between the pressing plate and the anchoring plate, the adjusting rod comprises an anchor bolt, a bolt and a connector, one end of the anchor bolt is fixedly connected with the anchoring plate, an isolation sleeve is disposed between the anchor bolt and the concrete plate, one end of the bolt is connected with nuts pressing the pressing plate, and the anchor bolt and the bolt are connected through the connector. The pressing plate and the anchoring plate are connected in a plurality of sections so that the length of the anchor bolt extending out of the concrete plate before installation is reduced, space is not occupied, and construction is not obstructed. The connector is connected and the diameter of the connector is larger than that of the isolation sleeve so that before the pressing plate is installed, the anchor bolt and the anchoring plate are not separated from the concrete plate when the anchor bolt collides due to a blocking function of installation of the connector.
Description
[technical field]
The present invention relates to a kind of girder steel fixture, especially a kind of suspension scaffold anchoring piece.
[background technology]
The tradition suspension scaffold adopts steel pipe as supporting mechanism, less stable, and suspension scaffold all adopts shaped steel as support in recent years, and it is way different fixedly, makes suspension scaffold support the economy and the safety that produce very large parameter has occured.
Application number discloses the removable anchor device of a kind of overhanging type steel girder steel in the patent documentation of " 201220176727.1 ", comprise the base plate be located on the concrete slab bottom surface and the overhanging type steel girder steel is fixed in pressing plate on the concrete slab end face, lay plastic sheeting and concrete slab isolation on base plate, four jiaos of base plates are vertically fixed respectively a screw rod, screw rod passes concrete slab and screw jacket has sleeve pipe and concrete slab isolation, four jiaos of pressing plates are socketed on screw rod, and nut is combined on screw rod and clamping platen downwards; This anchor device is detachable, can have enough to meet the need use, without waste, though the cost input is larger, but after turnover, average unit cost is low, and security performance is high, has ensured the safety in utilization of outrigger; But for connecting and regulating pressing plate, so screw rod is generally longer, easily bump at the work progress screw rod, affect construction operation, and can cause the bending of screw rod, affect it and use function, also easily cause potential safety hazard; Collision process during construction also may cause coming off of screw rod and base plate, causes security incident.
[summary of the invention]
The invention provides a kind of suspension scaffold anchoring piece, this anchoring piece does not affect normal construction, and can prevent the component accidental.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of suspension scaffold anchoring piece, comprise concrete slab, anchor slab and pressing plate, described anchor slab is located at bottom concrete slab, described pressing plate is pressed on girder steel between pressing plate and concrete slab surface, be provided with adjusting rod between described pressing plate and anchor slab, adjusting rod is regulated the distance between pressing plate and anchor slab, described adjusting rod comprises crab-bolt, bolt and adapter, described crab-bolt one end be fixedly connected with anchor slab and crab-bolt and concrete slab between be provided with separation sleeve, one end of described bolt is connected with the nut of clamping platen, and crab-bolt connects by adapter with bolt.
Further, described adapter is cylindrical shape, and the diameter of adapter is greater than the diameter of described separation sleeve.
Further, the first end of described switching is threaded with crab-bolt, and the adapter other end is connected with bolt thread.
Further, be provided with barrier film between described anchor slab and concrete slab.
Further, be provided with timber wedge between described adjusting rod and girder steel.
Further, the bottom of described pressing plate is provided with rubber layer.
Beneficial effect of the present invention:
At first, adjusting rod between suspension scaffold anchoring piece center platen of the present invention and anchor slab comprises crab-bolt, bolt and adapter, is divided into multistage, and crab-bolt is fixedly connected with anchor slab, again crab-bolt is passed through the adapter connecting bolt after placing steel beam, on bolt, the attaching nut makes pressing plate compress girder steel; Therefore only have a bit of crab-bolt to expose concrete slab before steel girder erection, take up room little, can not hinder construction;
Next connecting adapter on crab-bolt, adapter diameter are greater than the separation sleeve diameter, and before pressing plate and bolt were not installed, due to the barrier effect of adapter, when crab-bolt occurs to clash into, crab-bolt and anchor slab can not break away from concrete slab.
These characteristics of the present invention and advantage will be below the specific embodiment, accompanying drawing in detailed exposure.
[description of drawings]
The present invention is described further below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present invention.
[specific embodiment]
The invention provides a kind of suspension scaffold anchoring piece, comprise concrete slab, anchor slab and pressing plate, described anchor slab is located at bottom concrete slab, described pressing plate is pressed on girder steel between pressing plate and concrete slab surface, be provided with adjusting rod between described pressing plate and anchor slab, described adjusting rod comprises crab-bolt, bolt and adapter, described crab-bolt one end be fixedly connected with anchor slab and crab-bolt and concrete slab between be provided with separation sleeve, one end of described bolt is connected with the nut of clamping platen, and described crab-bolt connects by adapter with bolt.The suspension scaffold anchoring piece is detachable structure, can reuse, and reduces the waste of material.
Be explained and illustrated below in conjunction with the accompanying drawing of the embodiment of the present invention technical scheme to the embodiment of the present invention, but following embodiment is only the preferred embodiments of the present invention, is not whole.Based on the embodiment in embodiment, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belong to protection scope of the present invention.
With reference to figure 1, shown in a kind of suspension scaffold anchoring piece of the present invention, include concrete slab 2, anchor slab 3 and pressing plate 4, described anchor slab 3 is located at concrete slab 2 bottoms, described pressing plate 4 is pressed on girder steel 1 between pressing plate 4 and concrete slab 2 surfaces, be provided with adjusting rod between described pressing plate 4 and anchor slab 3, adjusting rod is positioned at the both sides of girder steel 1, and the distance of regulating between pressing plate 4 and anchor slab 3 by adjusting rod compresses girder steel 1.
Above-mentioned adjusting rod comprises crab-bolt 51, bolt 52, fixing many row's crab-bolts 2 on anchor slab 3, the outer socket separation sleeve 6 of crab-bolt 51, then at anchor slab 3 and the outer concreting plate 2 of separation sleeve 6, crab-bolt 51 is stretched out concrete slab 2 part connecting adapter 53 lower ends, after putting into girder steel 1 between crab-bolt 51, then at the upper end of adapter 53 connecting bolt 52, pressing plate 4 passes bolt 52, is screwed into nut 54 on bolt 52 tops and makes pressing plate 4 compress girder steels 1.Preferably, use double nut to be screwed into bolt and press down pressing plate.
