Description
Technical field
This utility model relates to one and ascends a height or by structure, in particular to the terraced beam direct connection device in a kind of Assembled stairs platform.
Background technology
Landing is except conventional concrete placings, also have steel construction and other material, its range of application has operation, visit, mainteinance repair, line balance converter pipeline passway and bridge landing, and port and pier, indoor and outdoor are meet or change the landing that building uses function to set up.
The mode of construction of landing has non-at-scene making in-site installation, field fabrication and installation, semifinished or finished goods assembling etc. Before fabrication and installation, generally want in-site measurement, and draw drawing by different configuration (particularly different gradient), then fabrication and installation. Field surveys workload is big and difficulty has ensured measurement accuracy, and some bulky pre-constructed unit, component bring difficulty also to the constructions such as lifting, transport, assembly, installation, anticorrosion and facing paint.
Additionally, due to the climatic factor such as the strong sunlight impact of rainy season in winter and summer, it is not easy to outdoor field fabrication, important place, fire-proof and explosion-proof and poisonous strategic point, production, life, commerce area, public place etc. make scene when simultaneously carrying out with installation need to do the protection isolation of necessity, to meet safety requirements, as long in the occupied ground time, to public transport, personnel are passing puts to no little inconvenience, and improve operating cost, reduce working performance, extend construction period.
At present, in Assembled stairs stage+module, the prolongation of ladder beam generally adopts the modes such as welding, Flange joint, overlap joint, telescopic joint and end face docking, above-mentioned connected mode is difficult to ensure that the security intensity of ladder beam, or increase other measure to ensure the security intensity of ladder beam, additionally, it is also possible to can cause ladder beam splice, when connecting, other parts are caused interference, cause difficulty of construction big, affect construction period, therefore, a kind of simple to operate, easy construction need to be designed and terraced beam direct connection device that security intensity is ensured.
Utility model content
The purpose of this utility model seeks to solve the deficiency of above-mentioned background technology, it is provided that a kind of simple to operate, easy construction and safe and reliable terraced beam direct connection device.
The technical solution of the utility model is: a kind of ladder beam direct connection device, including the casing mutually being wedged left-hand thread by two L-shaped connecting plates, the bottom surface of casing correspondence ladder beam end is provided with two faggings, in described fagging, is provided with the bracer being slidably matched with it.
Further, described connecting plate correspondence ladder beam end is provided with two link bolt hole, and described link bolt hole is arranged in outside described fagging.
Further, being inclined-plane inside described fagging, described fagging medial surface is provided with positioning runner; Described bracer includes the wedge shape slide plate being positioned at both sides and the connecting portion connected by both sides wedge shape slide plate, and described wedge shape slide plate arranged outside has the positioning sliding block coordinated with described positioning runner.
Closer, described connecting portion is provided with bolt hole, and the corresponding described bolt hole place of described connecting plate is provided with through hole.
A kind of ladder beam direct connection device of the present utility model, it is possible to directly adjacent ladder beam is connected, and simple to operation, and can guarantee that the security intensity of ladder beam.
Accompanying drawing explanation
Fig. 1 is that direct connection device of the present utility model arranges schematic diagram;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the fractionation schematic diagram of Fig. 2.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, the disclosed a kind of ladder beam direct connection device of the present embodiment, including some terraced beams 1, when ladder beam 1 needs extending length, it is possible to arrange direct connection device 2 between two be mutually butted terraced beams 1, so that the terraced beam length after docking meets instructions for use.
With reference to Fig. 2 and Fig. 3, the direct connection device 2 of the present embodiment includes mutually being wedged left-hand thread by two L-shaped connecting plates 2.1 and being bolted to connection all-in-one-piece casing, the bottom surface of casing correspondence ladder beam 1 end is provided with two faggings 4, in fagging 4, is provided with interior and that its outside tensioner can the be made bracer 3 that is slidably matched with it.
The connecting plate 2.1 of the present embodiment corresponding ladder beam end is provided with two link bolt hole 2.3, and connecting bolt 2.3 is arranged in outside fagging 4, by the cooperation of link bolt hole 2.3 and bolt, connecting plate 2.1 is arranged on ladder beam 1 end.
The present embodiment is inclined-plane inside fagging 4, and described fagging 4 medial surface is provided with positioning runner 4.1; Bracer 3 includes the wedge shape slide plate 3.1 being positioned at both sides and the connecting portion 3.3 connected by both sides wedge shape slide plate 3.1, and slide plate 3.1 arranged outside has the positioning sliding block 3.2 coordinated with positioning runner 4.1. Connecting portion 3.3 is provided with two bolts hole 3.4, and corresponding bolt hole 3.4 place of connecting plate 2.1 is provided with through hole 2.2.
Before the direct connection device of the present embodiment being arranged between two the terraced beams 1 needing docking, mounting groove need to be set at ladder beam 1 end face, distance between width and the fagging 4 of mounting groove matches, first bracer 3 is loaded between fagging 4, then fagging 4 is inserted in this mounting groove, bracer 3 is pushed, by fagging 4 spreading, support tightly on the mounting groove inner hole wall of ladder beam-ends face, ensure that the location of connecting plate 2.1 and ladder beam 1 end face, making it install stable, the pre-tightening tension simultaneously produced can undertake again partial shear, improves the bonding strength of ladder beam 1 and direct connection device 2.
The positioning sliding block 3.2 of the present embodiment slides in positioning runner 4.1, make bracer 3 can only slide along the setting direction of positioning runner 4.1, and owing to wedge shape slide plate 3.1 is wedge shape, wedge shape slide plate 3.1 is not only made to slide smooth and easy, can also make wedge shape slide plate 3.1 and fagging 4 inwall is that face contacts, it is ensured that the bracer 3 tension force to fagging 4.
The bracer 3 of the present embodiment is adjusted by bolt, the through hole 2.2 of screw bolt passes connecting plate 2.1 and the bolt hole 3.4 corresponding with through hole 2.2, the bolt scalable bracer 3 displacement in fagging 4, and then regulate the tensile force size of its generation, make the bonding strength of ladder beam 1 and direct connection device 2 meet instructions for use.
The above, be only preferred embodiment of the present utility model, and structure of the present utility model is not done any pro forma restriction. Every any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, all still falls within the scope of the technical solution of the utility model.
