Description
Technical field
The utility model relates to the technical field of construction of railway or highway bridge, during particularly a kind of employing cantilevered construction casting continuous beam and the matching used Hanging Basket steel form of Hanging Basket.
Background technology
The Hanging Basket steel form is the railway of large span and a kind of indispensable equipment that highway cantilevered continuous placing bridge is used, when adopting Hanging Basket to build Longspan Bridge, be not subjected to the influence of factors such as bridge pier height, river be dark, directly extend construction to striding the footpath direction piecemeal from the bridge pier top of having built up.This pouring construction process has not only been simplified the difficulty of construction of Longspan Bridge, and can save duration and the expense of setting up full framing etc. greatly, and extremely unit in charge of construction welcomes.And in the prior art, the structure of Hanging Basket steel form is more complicated all generally, admittedly be difficult to satisfy the requirement that the disconnected cross section of bridge Continuous beam design constantly changes.Present domestic different kinds of roads are in the construction of continuous beam, when rectangle hole width size changes gradually in beam face, beam bottom width degree and the beam, mostly adopt wooden form or take between two steel forms down to go into the way of concentric reducer plank, not only the presentation quality to bridge has certain influence, and the wave given up a large amount of timber and the preparation man-hour.Retrieved a large amount of interrelated datas, do not seen so far at home and utilize direct solution to this problem of steel form or relevant patent.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, by a kind of and simple in structure, easy for installation, construction saving, wide accommodation and lower-cost novel Hanging Basket steel form are provided.
To achieve these goals, the utility model is by the following technical solutions:
It comprises exterior sheathing, interior top template, interior mould holder, soffit formwork, and interior top template, interior mould holder are located at the middle part of exterior sheathing, and soffit formwork is located at the bottom of exterior sheathing, and Screw arbor with nut at both-ends is located at the top of exterior sheathing, interior top template be installed in mould holder above.
Described exterior sheathing comprises the adjusting device of normal reach master module, 0# section template, secondary template, flank template, flank template; Secondary template is mounted in the bottom of master module, and the flank template is installed in the top of described master module, and the adjusting device of described flank template is fixed on the top of the fixed mount of master module.
Described secondary template can be a joint, also can be divided into more piece, and after being poured into the height of beam section depth of section less than described master module, the secondary template of described exterior sheathing can be separated with described master module dismounting.Secondary template can be removed according to the actual merogenesis that requires of Construction of continuous beam environment, the purpose one of this structure setting is to alleviate the phenomenon of template deadweight because of increasing exponentially with cantilever lengthening gravity, the 2nd, strengthened the spatial altitude under the construction beam section, the vehicle of having guaranteed not influence in work progress below the bridge is normally current, this point at trans-city main line, stride railway, stride in the middle of the bridge construction of speedway by for important.
Described flank template realizes regulating the adjustment that greatly facilitates the two-way butt joint of continuous beam.
In described top template comprise in top template, a pair of the right on symmetrical a pair of left side in push up in top template and one pair in template.
Mould holder in described whenever is with 4～8 pairs, two body frames of described interior every pair of left and right symmetry of branch of mould holder, and middle connection batten and the adjusting screw(rod) used connects; The two ends of described adjusting screw(rod) are left and right hand thread, and described left and right two body frames are respectively equipped with the left-handed nut and the nut of dextrorotation, are provided with some fastening bolts on interior mould holder.After having unscrewed fastening bolt,, can require to regulate the width of described interior top template according to the thickness of abdominal wall of institute's casting beams section by rotating described adjusting screw(rod).
In described in the interior top of top template the width of the panel of template form both wings greater than its collet, its wing limit have part ride on the left side in top template in the top template and the right above, on the described interior top template support bar is set.The width on its wing limit should be greater than the required maximal regulated distance of beam inside ceiling panel, top template also is included as the wing limit that prevents panel and causes diastrophic support bar because of pressurized is excessive in described, the material of described support bar is a batten, also with the left side in the shaped steel of the contour size of top template in top template and the left side.
Described soffit formwork comprises template at the end, the right template of the end left side template and the end; The width of the panel of template forms both wings greater than its pallet at described the end, in the described soffit formwork support bar is set.The width on its wing limit should be greater than maximal regulated distance required at the bottom of the beam.Described soffit formwork also is included as distortion is caused on the wing limit that prevents panel because of pressurized is excessive support bar, and the material of described support bar is a batten, also with the shaped steel of the contour size of the right template of the end left side template and the end.
Described Hanging Basket steel form is to cooperate Hanging Basket to carry out the construction of continuous beam, and the front beam of described Hanging Basket and hang and draw assembly to hang the front and back ends that hauls outer slippage beam is respectively hung the exterior sheathing of both sides; Top template and interior mould holder are hung by the interior slippage beam of described Hanging Basket and draw in described; Described soffit formwork is then being held in the palm by the end indigo plant of described Hanging Basket, hangs the described soffit formwork that highly raises of hanging that draws assembly by regulating.
The 0# section template of described exterior sheathing is promptly removed after having built 0# beam section, by the normal reach master module of described exterior sheathing, secondary template and described in top template, interior mould holder, soffit formwork, Screw arbor with nut at both-ends etc. hanging of Hanging Basket draw carry out the building of 1# beam section under the effect after, only need unclamp the Screw arbor with nut at both-ends of steel form and the anchoring piece of Hanging Basket, steel form and Hanging Basket just can be whole on sliding rail by spurring slippage together and arrive next beam fragment position with pulling Hu Lu, anchoring piece and Screw arbor with nut at both-ends are installed the back just can carry out building the cycle of another beam section, close up until full beam.
The utility model compared with prior art has following advantage: the utility model is simple in structure, easy for installation, construct saving, wide accommodation and cost are lower.
