Provided is a windproof prefabricated part assembly and connection device. The windproof prefabricated part assembly and connection device comprises a windproof prefabricated part embedded steel plate, a connection structural steel, flange steel plates and connection bolts, wherein one end of the connection structural steel is connected with the flange steel plates in welding mode, the other end of the connection structural steel is connected with the windproof prefabricated part embedded steel plate, and the flange steel plates are connected through the connection bolts. The windproof prefabricated part assembly and connection device simplifies windproof prefabricated part assembly and connection process and has the advantages of being simple in installation process and effectively improving assembly accuracy and efficiency of large-scale prefabricated parts.
Description
Technical field
The utility model relates to a kind of windproof splicing prefabricated components linkage.
Background technology
Certain railway the second double line engineering is through the strong wind district, and strong wind mostly is the Gobi desert in the district, and natural conditions are abominable, and are meagrely-populated, and wind speed is high, the wind phase is long, and the speed that blows is fast, and especially Bai Lifeng district, three Shi Lifeng districts are one of the most powerful areas of landlocked wind-force.
Resist the harm that cause in the strong wind area for the windproof open cut tunnel engineering of above domestic the first of background China's autonomous Design, my company carries out the first windproof open cut tunnel test section construction in the Bai Lifeng district.Windproof open cut tunnel engineering and ordinary crossing engineering More different, at first the aperture is much larger than common two-wire railway tunnel, secondly windproof open cut tunnel adopts prefabricated pipe section to be assembled into ring, adopts first reinforcing bar to connect the mode that is rigidly connected of concreting between the section of jurisdiction again, and construction technology far is different from ordinary crossing.
The hoop assembly unit is adopted in windproof open cut tunnel prefabricated units design, and seam adopts first reinforcing bar directly to connect the concrete mode that is rigidly connected of after-pouring, and the problem that this kind form exists is:
1, the prefabricated precision of prefabricated units is low, of poor quality in the existing windproof open cut tunnel test section work progress; There is the small-size concrete piece to drop when section of jurisdiction ring is with loop contacts in the assembly unit process, in case have the phenomenon that drops, the disease that can cause then that assembly unit is of poor quality, efficient is low etc. and can't renovate.
2, windproof prefabricated units are designed with five kinds of different connection form, and secondly reinforcing bar is indenting in the assembly unit process, interfere with each other, and the aligning accuracy requirement is high, constructional difficulties, and the installation work consuming is consuming time, and the application life and the driving that affect windproof prefabricated units of later stage are steady.
3, four angle points of windproof open cut tunnel pipe sheet assembling are very difficult consistent with a upper anchor ring, cause the stressed and sedimentation and deformation of windproof open cut tunnel section of jurisdiction inhomogeneous, and entire effect substructure and profile are not attractive in appearance.
4, wet seam connecting reinforcement welding needs assembly unit equipment to cooperate with concreting, and the equipment turnover rate is low.
The utility model content
Its purpose of the utility model just is to provide a kind of windproof splicing prefabricated components linkage, has the simple characteristics of installation process, and Effective Raise splicing accuracy and the efficient of assembly unit Large Precast Members.
The technical scheme that realizes above-mentioned purpose and take, comprise windproof prefabricated units pre-embedded steel slab, also comprise and connect shaped steel, flange steel plate and connecting bolt, described connection shaped steel one end and flange Plate Welding, the other end is connected with windproof prefabricated units pre-embedded steel slab, is connected and fixes with connecting bolt between the flange steel plate.
Compared with prior art, the utility model has the advantage of, by comparing with design assembly unit connected mode, the practical operation proof adopts the windproof prefabricated units of the interim connected mode assembly unit of shaped steel, can effectively solve the problem of assembly unit quality, have good looking appearance, whole stressed, the characteristics that work progress is simple, safety is controlled, and can greatly improve the turnover rate of splicing prefabricated components equipment.
Description of drawings
Below in conjunction with accompanying drawing this practicality newly is described in further detail.
Fig. 1 is this apparatus structure schematic diagram.
Fig. 2 is A-A sectional view among Fig. 1.
The specific embodiment
This device comprises windproof prefabricated units pre-embedded steel slab 4, as depicted in figs. 1 and 2, also comprise and connect shaped steel 5, flange steel plate 7 and connecting bolt 6, described connection shaped steel 5 one ends and 7 welding of flange steel plate, the other end is connected with windproof prefabricated units pre-embedded steel slab 4, and it is fixing with connecting bolt 6 between the flange steel plate 7 to be connected.
Described connection shaped steel 5 is the I25b i iron, and described connecting bolt 6 is the M24 bolt.
Described windproof prefabricated units pre-embedded steel slab 4 connects main muscle 2 and anchor bar 3.
Described windproof prefabricated units pre-embedded steel slab 4 is arranged in the prefabricated reinforced concrete structure 1.
The interim connection of Large Precast Members assembly unit is that windproof prefabricated units are provided with to connect shaped steel 5 and connect the after-pouring rigid concrete for the prefabricated units hoop.Be connected to windproof prefabricated units to the structure design size by connecting shaped steel 5 connection design sizes.Connecting shaped steel 5 connections is to be made of I25b i iron and flange steel plate 7, M24 connecting bolt 6 supporting nut designs.Described I25b i iron one termination and 7 welding of flange steel plate, and the other end of I25b i iron is connected with windproof prefabricated units pre-embedded steel slab 4; Be used for large-scale windproof prefabricated units hoop is laterally connected at described flange steel plate 7, M24 connecting bolt 6 supporting nuts.
The interim connected mode characteristics of the new Large Precast Members (windproof open cut tunnel section of jurisdiction) of this practicality also are:
Described I25b shaped steel is set to pre-bending shaped steel, and the pre-bending direction of described I25b shaped steel is the circular arc direction of Large Precast Members.
Described flange shaped steel connects can be firmly, work progress is simple, splicing accuracy is high, to connect four angle points be a face in the section of jurisdiction and be assembled into an anchor ring and become whole and substructure is affected very little, can prolong section of jurisdiction application life and construction safety.
