Description
Technical field
The invention belongs to bridge pier pouring construction field, relate to a kind of bridge pier pouring construction template, especially a kind of adjustable form of bridge variable cross-section high pier construction.
Background technology
Normally segmentedly in Bridge High-pier post work progress build, before a sections is built, first installation form, is bolted fixing between the edge of adjacent forms, then build this sections concrete.After a sections has been built, need the template of next sections to dismantle, be installed to a sections and continue construction.When bridge pier cross dimensions is constant, the template of next sections directly can be turned over mould and install to a upper sections.But at present in bridge construction, for reducing engineering cost, also in order to the aesthetic feeling of structure, often bridge pier column is designed to variable cross-section, adopt certain slope ratio (commonly using as 40:1,60:1 or 80:1), pier stud shape is that little bottom, top is large.Common like this construction method is just inapplicable.Because pier stud is more upwards constructed, template needs according to slope than constantly inwardly shrinking, and must be bolted fixing between the edge of adjacent forms, therefore unit in charge of construction has been the pier stud pouring construction of variable cross-section, or need the template of processing multiple cross dimensions, after a sections has been built, need to select the template of appropriate size to install at a upper sections, so just caused template to drop into greatly; Or by the suitable cutting of lower joint template, then be installed to a sections, to adapt to the continuous reduction of upper joint cross dimensions, cause the template after cutting to be difficult to reuse like this, and the seam of template after cutting and connection part of templates is wayward, affects pier stud and builds presentation quality.
Summary of the invention
The object of this invention is to provide a kind of template of applicable variable cross-section high pier construction, reduce the template cost of Bridge High-pier construction, simultaneously easy and simple to handle in work progress, there is the advantages such as controllability, safety be stable.
Technical scheme of the present invention is as follows:
A kind of bridge variable cross-section height pier adjustable form, comprise two block gap certain distances be parallel to each other and with the fixed form of horizontal plane, it is characterized in that: the lateral surface of every block fixed form, establish at least 3 horizontal back cords in the horizontal direction, the two ends of the horizontal back cord of every bar grow described fixed form both sides of the edge certain length respectively, are connected between the end of two horizontal back cords that two fixed form the same side height are identical by connecting rod; Between two fixed forms, near the both sides of the edge of described two fixed forms, be provided with two pieces of adjustable formworks, the dual-side of described adjustable formwork is fitted with the medial surface of two fixed forms respectively; By connecting pull bar between described two fixed forms, adjustable formwork described in every block is connected by adjusting screw with between the connecting rod be adjacent.
The dual-side that the medial surface of above-mentioned adjustable formwork and described fixed form is fitted is equipped with chamfering.
The present invention is applicable to the one-sided variable cross-section pier stud construction of Bridge High-pier, greatly can reduce the template cost of the one-sided variable cross-section pier stud construction of Bridge High-pier, achieve the recycling of template.The present invention adjusts the spacing of two ends adjusting template and connecting rod by adjusting screw, realize the continuous change at pier stud sectional dimension two ends, do not need between template to be bolted, change in this type of engineering construction and template is constantly carried out cutting, with meet that structure section size constantly changes requirement, there is easy and simple to handle, that controllability is strong advantage, improve workmanship and security and stability simultaneously.Because the present invention does not need to carry out to saving template under pier stud the requirement that cutting meets the reduction of upper joint template cross dimensions, therefore the concrete presentation quality of the pier stud corner of casting complete is stable, greatly improves the concrete presentation quality of pier stud.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, the present invention includes two block gap certain distances be parallel to each other and with the fixed form 1 of horizontal plane, the lateral surface of every block fixed form 1, establish at least 3 horizontal back cords 2 in the horizontal direction, the two ends of the horizontal back cord 2 of every bar grow fixed form both sides of the edge certain length respectively; Connected by connecting rod 3 between the end of two back cords that two fixed form the same side height are identical; Between two fixed forms 1, near the both sides of the edge of two fixed forms, be provided with two pieces of adjustable formworks 4, the dual-side of every block adjustable formwork 4 is fitted with the medial surface of two fixed forms 1 respectively, by connecting pull bar 5 between two fixed forms 1, every block adjustable formwork 4 is connected by adjusting screw 6 with between the connecting rod 3 be adjacent.
For ensureing the presentation quality that pier stud is built, the present invention can all arrange chamfering 7 at the dual-side of described adjustable formwork.
Adjusting screw 6 presets two nuts 8 in connecting rod both sides, after adjustable formwork adjustment puts in place, by nut 8, adjustable formwork is fixed.
When the present invention specifically implements, template can at specialized factory's processing and fabricating.As a kind of specific embodiment, the panel of fixed form and adjustable formwork all adopts the steel plate of 6mm, all establishes horizontal back cord outside fixed form and adjustable formwork.Horizontal back cord adopts 2 × and [channel-section steel and the panel of 10 are welded into integral mold plate, and wherein on fixed form, the two ends of every bar transverse direction back cord grow fixed form both sides of the edge at least 20cm respectively.
Connecting rod adopts 2 × and [channel-section steel of 14, adopts the finish rolling deformed bar of φ 25mm to pull bar, adjusting screw adopts diameter to be the rod iron of 50mm.
Pier stud is divided into contour multiple sections during construction, step pouring from bottom to top, by hand fit's over-form construction.First install first segment template, template uses tower crane lifting, and two fixed forms are reinforced by pull bar, overlap pvc pipe to outside pull bar.After two adjustable formworks are adjusted to predetermined gradient, be connected with connecting rod by adjusting screw, and by the nut 8 that adjusting screw is preset, adjustable formwork fixed, as shown in Figure 1.Then first segment concrete is built.
After first segment has been built, the template of first segment is installed second section template, mounting means is with first segment template.After complete second section concrete to be cast, and when the concrete strength of first segment template reaches requirement, start to turn over mould and carry out Section of three construction.Remove first segment template and template surface is cleaned out, after coating release agent, turned over to rise in second section template with tower crane and installed, the pitch of adjustment adjusting screw, adjustable formwork is made to reach the default gradient of this sections, be fixed and build Section of three concrete, circulation like this is upwards built, and often upwards one saves, adjustable formwork inwardly has contraction to a certain degree according to the slope ratio of design, as shown in Figure 4, thus realize the change of pier stud section, until reach pier stud design height.
