The utility model has the advantages that: solved the key technology problem that cast -in -place continuous beam beiLei beam support was dismantled effectively, than in the past through hydraulic jack, installation sandbox safer, more swiftly, more reliable, can accelerate ann's speed of tearing open of beiLei beam support simultaneously, reduced construction cost, improved productivity.
Description
Technical field
This utility model relates to a kind of easy device dismantling Bailey beam support, it is mainly used in the cast-in-situ box girder that engineering Bailey truss is set up, owing to cast-in-situ box girder is after concreting completes, between Bailey beam support and box beam and column very close to each other, Bailey beam cannot be removed, can make Bailey beam support safely, quickly, smoothly remove by this device, it is to avoid conventional installation sandbox efficiency is low and installs the shortcomings such as hydraulic jack cost is high, unstable.
Background technology
Continuous increase along with China's infrastructure construction scale, newly-increased highway, the construction of railway are increasing, newly-increased railway, highway bridge have and much all adopt scene to set up Bailey beam support cast-in-place concrete, in Bailey beam rack construction, dismounting Bailey beam support is always up the technological difficulties of Bailey beam construction, the sandbox dismounting method before adopted and default hydraulic jack method, efficiency of construction is low, construction cost is high, and safety coefficient is low, has a strong impact on the construction period simultaneously.
Utility model content
This utility model overcomes existing shortcoming in the art, provide a kind of easy device dismantling Bailey beam support, simple in construction, convenient to operation, use safety, it is achieved that the quick dismounting of Bailey beam, have updated the dismounting technique of Bailey beam, greatly reduce labor strength.
The technical solution of the utility model is: a kind of easy device dismantling Bailey beam support, including upper bracket, hold-down support and two pieces, left and right lateral adjustment bearing, wherein: two pieces, left and right adjustment bearing connects into entirety by adjusting screw rod, and adjusting screw rod both sides are provided with adjusting bolt; Described upper bracket and hold-down support are processed into catwalk shape, are symmetricly set between two pieces of lateral adjustment bearings, and the catwalk of upper bracket is up big and down small, and the catwalk of hold-down support is up-small and down-big; Fit clearance between the side of upper bracket and hold-down support catwalk and two pieces of lateral adjustment bearings is zero.
Further, described lateral adjustment bearing is processed into half catwalk shape.
Further, between described adjusting bolt and adjusting screw rod it is internal and external screw thread matched in clearance; Further, described matched in clearance is gap is the cooperation of zero.
Further, the catwalk height of described upper bracket and hold-down support is 70mm to 100mm.
Compared with prior art, the utility model has the advantages that: have updated the key technical problem of dismounting Bailey beam, it is possible to reach the purpose of dismounting Bailey beam quickly and easily, accelerate the project progress of box girder construction simultaneously, reduce construction cost, improve labor productivity.
Accompanying drawing explanation
This utility model will illustrate by example and with reference to the appended drawing, wherein:
Fig. 1 is this provision for disengagement front view before dismounting Bailey beam;
Fig. 2 is this provision for disengagement front view after dismounting Bailey beam.
Detailed description of the invention
A kind of easy device dismantling Bailey beam support, as depicted in figs. 1 and 2, including: upper bracket 2, lateral adjustment bearing 3, adjusting bolt 4, adjusting screw rod 5, hold-down support 6, wherein:
Two pieces, left and right lateral adjustment bearing 3 is connected with adjusting bolt 4 by adjusting screw rod 5, and wherein upper bracket 2 and hold-down support 6 are between two pieces of lateral adjustment bearings 3, and wherein hold-down support 6 is fixed in distribution beam 7.
Two pieces, described left and right adjustment bearing 3 connects into entirety by adjusting screw rod 5, then is fastened from two ends by adjusting bolt 4. Lateral adjustment bearing 3 is processed into half catwalk shape, is to reduce between lateral adjustment bearing 3 and upper bracket 2, and the force of sliding friction between lateral adjustment bearing 3 and hold-down support 6, can prevent again upper bracket 2 from coming off in moving process simultaneously; Half catwalk shape of lateral adjustment bearing 3 simultaneously, it is also possible to making lateral adjustment bearing 3 slip down to when contacting with distribution beam 7 is face contact, reduces the impact to distribution beam 7.
Described adjusting screw rod 5 must assure that its tensile strength reaches requirement, and being distributed in the external screw thread on lateral adjustment bearing 3 both sides with coordinating of the female thread of adjusting bolt 4 must be the matched in clearance of zero for gap.
Described upper bracket 2 and hold-down support 6 are between two pieces of lateral adjustment bearings 3, upper bracket 2 and hold-down support 6 are processed into catwalk shape, ensureing that the catwalk plane of the two can be fully mated, between upper bracket 2 and hold-down support 6 and lateral adjustment bearing 3, fit clearance is zero.
Described hold-down support 6 is mobile in order to prevent, and is separately fixed at distribution beam 7 on request, and hold-down support 6 plays the effect of location, it is ensured that divide equally Bailey beam support 1.
This adjusting apparatus forms with common iron is cleaved, material is easy to get, technique is simple, with low cost, can conveniently use, simultaneously can also reclaiming, economize on resources.
This adjusting apparatus according to the requirement to lift, can process different size of main component. The catwalk height of upper bracket 2 and hold-down support 6 is 70mm to 100mm so that the maximum moving distance up and down of this covering device can reach 120mm, can meet the dismounting of all kinds of Bailey beam support.
This device specifically includes that upper bracket, lateral adjustment bearing, adjusting bolt, adjusting screw rod, hold-down support, wherein lateral adjustment bearing is connected with adjusting bolt by adjusting screw rod, upper bracket and hold-down support are between lateral adjustment bearing, hold-down support is fixed in distribution beam, under Bailey beam poppet pressure, upper bracket is made to move up and down by regulating the adjusting bolt at adjusting screw rod two, simultaneously, lateral adjustment bearing moves up and down itself, so that Bailey beam moves up and down, reach the purpose of dismounting Bailey beam support. Dismantle Bailey beam support by this device and namely can ensure that stablizing of support, it is unnecessary to the convenience of dismounting and full hall frame is set at Bailey beam frame upper, simplify operation, it is effectively improved the progress of construction, greatly reduce the workload of workmen, improve work efficiency, save cost simultaneously.
This apparatus structure is simple, convenient to operation, use safety.Efficiently solve the key technical problem of cast-in-situ continuous beam Bailey beam support dismounting, than ever by hydraulic jack, install sandbox safer, faster, more reliable, the peace that simultaneously can accelerate Bailey beam support tears speed open, reduces construction cost, improves labor productivity.
