Description
Technical field
The utility model relates to technical field of bridge construction, the square sand cylinder of particularly a kind of steel tube frame top load-bearing.
Background technology
Bailey bracket, also known as beret truss, Bailey beam or truss, is being invented, to solve the needs of durante bello bridge fast erecting, and with his naming by a Britain engineer at first in World War II.Bailey beam has the features such as structure is simple, mounting or dismounting are convenient, combination is flexible, convenient transportation, erection is quick, interchangeability good, strong adaptability, be widely used in Urban Bridge supporting system, often as use such as make-shift bridge, cast in place concrete form support, spelling portal frames.
After engineering construction completes, need to remove Bailey bracket.When adopting post and beam steel pipe Bailey truss in cast-in-situ bridge construction method, mode of unloading mainly adopts timber wedge to unload, and minority adopts circular sand cylinder to unload, and their pluses and minuses are: the advantage of timber wedge is that control Beam Elevation is more accurate; Shortcoming is that workload is large, and wood material consumption is large, long in time limit; Vibrate easy landing; Increase the base plate formwork structure number of plies, cause base plate template settling amount to increase; Unload by beaing dismounting timber wedge, timber wedge waste is large; The equal hanging operation of gross area, security risk is high, and after removing, place is in disorder, and Effect Field holds field looks, and pile workload is large.Relative timber wedge, the advantage of circular sand cylinder saves timber wedge in base plate formwork structure layer and the bottom lumps of wood, saves material, reduces bed die settling amount; Unload terminal-velocity degree fast, the duration is short; Unload drop point and be positioned at steel pipe buttress place, handling safety, construction plant is clean; Bearing capacity is large and unload height amplitude comparatively large (in the construction of bridge rack template, bearing capacity is generally no more than 500KN, unloads drop height degree and generally reaches 5cm).
Figure 1 shows that prior art adopts the schematic diagram of circular sand cylinder, circular sand cylinder comprises upper cover 1 and lower cover 2, and upper cover 1 is nested in lower cover 2, and lower cover 2 is provided with and unloads sand mouth 3.During use, in lower cover 2, fill sand, then upper cover 1 is put into lower cover 2, the top and bottom of circular sand cylinder are welded between the crossbeam 6 under steel pipe column 7 and Bailey bracket.Need weld to adopt gas cutting to cut open when removing Bailey bracket, take apart and unload sand mouth, sand unloads, and upper cover 1 sinks, then removes Bailey bracket.The shortcoming of circular sand cylinder be particularly different object of construction production even the steel pipe column caliber that adopts of same project is not necessarily identical, generally adopt Φ 380-630mm, during installation must caliber identical, cause turnover to use limitation; Install, remove comparatively inconvenience, must up and down tube wall alignment firm welding during installation, adopt gas cutting to cut open during dismounting again; Circular sand cylinder highly about 40cm, in order to increase supporting capacity, be cast with concrete in upper cover 1, weight is about 240-360kg, inconvenient operation; Integrated construction cost is high.Existing this circular sand cylinder mode of unloading saves material than timber wedge, reduce the duration, but its major defect limits promoting the use of of circular sand cylinder.
Given this, the applicant develops a kind of sand cylinder overcoming above defect specially, and this case produces thus.
Utility model content
The purpose of this utility model is the square sand cylinder providing a kind of steel tube frame top load-bearing, achieves installation, removes conveniently, easy to operate, low cost and other advantages.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of square sand cylinder of steel tube frame top load-bearing, it is characterized in that: comprise upper cover, lower cover, unload sand mouth, suspension hook, described upper cover, lower cover are square structure, described upper cover is nested in lower cover, upper cover has upper surface and soffit, a vertical passage is offered between upper and lower surface, under cover and be provided with bolt hole, by bolt, upper cover, lower cover are connected into as a whole, bolt is fixed on down through passage and covers, and upper cover vertically can move up and down in the altitude range of passage in lower cover; Describedly unload the bottom that sand mouth is arranged in lower cover; Suspension hook is arranged in the front and rear surfaces of lower cover.Adopt square sand cylinder, can not be subject to the restriction that steel pipe column caliber is different, all can adopt this square sand cylinder for different calibers, the scope of application is wide.Design this and cross acting as of channel bolts: prevent the front and rear surfaces of lower cover under the effect of carrying, the effect of sand causes front and rear surfaces lateral deformation; Make upper and lower covers become as a whole, be convenient to sale, transport etc.; Play position-limiting action to upper cover, when upper cover is maximum settlement height, the soffit that this bolt can limit upper cover moves up further; Ensure that the center of gravity of sand is positioned at centre position.
Further, be provided with several vertical steel plates between the upper and lower surface of described upper cover, welding between the upper and lower surfaces.Vertical steel plate plays strengthens stressed effect, strengthens the supporting capacity of upper cover soffit.
Further, described suspension hook has two, is located on lower cover front and rear surfaces diagonally opposing corner position.Adopt in this way, suspension hook only need arrange two, saves material and more lifting is stable, rise to cod tin time, only these two suspension hooks need be hung sand cylinder of just can steadily slinging.
Further, the front and rear surfaces of described lower cover is provided with cross reinforcing, and described reinforcing rib is positioned at below bolt hole.
Further, described in unload sand mouth and be provided with cover plate, described cover plate is bolted on and unloads on sand mouth, prevents sand from dropping.When dismantling Bailey bracket, unloading bolt, unloading lower cover, sand just can removal, easy to operate.
Further, described in unload sand mouth and be provided with three, wherein two are arranged in the two ends in lower cover front, a centre position being arranged in the lower cover back side.This kind of design can also can complete fast while meeting bearing capacity unloads sand.
Further, described upper and lower surface adopts block steel plate.
The technical program has the following advantages:
Precisely Beam Elevation is controlled by unloading to sand; Adopt square structure, can be general to the steel pipe column of different tube diameters, applied widely; Install, remove conveniently, can not need during installation to weld.Circular sand cylinder is stressed in order to ensure, usually can in upper cover casting cement, cause sand cylinder very heavy, the utility model is lightweight, installs, transports more convenient, also can reduce security risk.Improve fitting operation environment, reduce the duration, save construction cost; Effective reduction rack template construction safety risk; Turnover use economizes on resources.Also can be used as other and carry lowering device temporarily.
