Abstract
The utility model relates to a double-faced framework erection steel bracket, which is characterized in that: a main body comprises a beam and two groups of rod pieces which are welded at the same side of two ends of the beam, each group of rod pieces comprises a long rod at the outer side and a short rod at the inner side, and the short rod is provided with a nail hole. A vertical outside formwork can be erected by the long rod at the outer side of the steel bracket, an inside formwork can be fixed in a suspended way by the short rod through a screw bolt or an iron nail, and the bottom space is vacated. When a channel is cast-in-place, channel walls at two sides of the channel and channel bottom can be cast-in-place and one-time molded by two groups of inside and outside frameworks which are matched with the flat ground surface, the cast molding channel has good integrality and has no seam, the channel wall and the channel bottom are in a connecting structure, the whole rigidity is good and the service life is long.
Description
Technical field:
The utility model relates to a kind of site operation and is used for the two-sided formwork erection steel bracket that support shuttering is used.
Background technology:
The field irrigation canals and ditches are divided into row, feed ditch two classes substantially.Escape canal is based on barnacle, can adopt laid dry or grouts.The field irrigation water channel is based on concrete body canal, adopts generally that concrete gives that clamp dog is built by laying bricks or stones, Cast-in-place concrete or U type groove concatenation construction technology.Comprehensive each existing construction technology, the pluses and minuses division of its existence is as follows: it is simple that the U-lag canal has construction technology, the characteristics that cost is lower.But its joint is many, and every kilometer reaches 1000 joints, and construction quality is difficult to control, mainly is that support slot body basis, joint jointing are difficult.So application life is short, general time limit 3-5.Advantages such as precast concrete block is built canal by laying bricks or stones and had construction simply, and section is easy to control, and cost is low.But concrete gives clamp dog and produces house by specialty and produce, and quality is unsecured, service life 10-20.The cast-in-place canal of post forming adopts the cast-in-place operation of twice, at the bottom of the canal and the canal wall be shaped separately, globality is relatively poor, the canal cross section of especially big section is stable inadequately, the canal wall easily collapses.Cast-in-place one-time formed template supported setting at the bottom of how a kind of Qu Qiang, canal were provided, and promptly became the object of the utility model research.
Summary of the invention:
The purpose of this utility model is to design a kind of two-sided vertical template that supports, in order to the two-sided formwork erection steel bracket of thin-walled rectangle concrete water channel cast-in-place construction.
Technical solutions of the utility model are achieved in that a kind of two-sided formwork erection steel bracket, it is characterized in that main body comprises a crossbeam and two groups of rod members that are welded on crossbeam two ends homonymy, every group of rod member comprises a stock and an inboard quarter butt in the outside, offers hole for nailing on the quarter butt.Steel bracket outside stock can be set upright vertical outboard template, and quarter butt can pass through bolt or the unsettled fixedly inner side template of iron nail, and vacates bottom space.When concrete is built, cooperate smooth ground by outboard template in two groups, making can once cast-in-place moulding at the bottom of channel both sides Qu Bi and the canal.
The utlity model has reasonable in design, simple in structure, convenience operation, can support two-sided vertical template, construct in order to the Cast-in-place concrete channel, make the channel good integrity of building moulding, no seam, conjoined structure at the bottom of Qu Bi and the canal, integral rigidity is strong, long service life.

The specific embodiment:
With reference to Fig. 1, a kind of two-sided formwork erection steel bracket, its main body is welded by angle steel, comprise a crossbeam 1 and two groups of rod members that are welded on crossbeam two ends homonymy, every group of rod member comprises a stock 2 and an inboard quarter butt 3 in the outside, offer hole for nailing 31 on the quarter butt 3, make things convenient for the unsettled fixedly inner side template 4 of iron nail or bolt; Also can offer hole for nailing on the stock 2, convenient fixedly outboard template 5.The high difference of outboard template 5 and inner side template 4 equals to design the thickness at the bottom of the canal; The spacing of the difference of stock 2 and quarter butt 3 and stock 2 and quarter butt 3 is suitable, and the thickness that the spacing of stock 2 and quarter butt 3 deducts the medial and lateral template equals to design the thickness of canal wall.
In addition, as shown in the figure, described crossbeam 1 is an extensible canopy, and this crossbeam 1 is divided into two sections, and two sections infalls all offer slotted eye 11, lock together by a bolt at least.Unclamp bolt and can regulate the length of crossbeam 1, to satisfy the construction demand of different channel width.Certainly the stretching structure of crossbeam 1 also can adopt the flexible routine techniques scheme that waits of sleeve pipe to realize.
With reference to Fig. 2, Fig. 3 and Fig. 4, fix a support bar 63 of inboard two quarter butts, this support bar 6 can directly be welded on angle steel 3 of two quarter butts, the batten that also can adopt summary to grow any substitutes, before building, be supported between two quarter butts, play reinforcement effect, be subjected to concrete side pressure when avoiding building, and make quarter butt 3 distortion, influence canal face quality.If crossbeam 1 is the extensible canopy structure, support bar 6 also corresponds to the expansion link structure with it so, reaches synchronous corrective action.In addition then, be welded with a steel plate 7 respectively towards template one side at stock 2 and quarter butt 3, steel plate 7 width between 15-30cm, the seam of utilizing this steel plate 7 to come support shuttering lap-joint, as shown in Figure 3.Can on the crossbeam 1 of template one side, be welded with a supporting rod 8 at stock 2 and quarter butt 3 again, this supporting rod 8 cooperates with stock 2 and quarter butt 3 can press from both sides positive template, make in fixing to need not outboard template 4,5 o'clock between two templates, to add support member in addition, can guarantee the spacing of two templates.
With reference to Fig. 3, steel bracket can be processed into two kinds of structures, and a kind of long and short bar 2,3 band steel plates 7 are in order to reinforcing template lap-joint, and is another kind of for not being with the steel plate steel bracket, in order to the frame continuous template that is connected, selects during confession frame shuttering.Certainly, steel bracket also can only be used a kind of structure, and in template lap-joint, can reinforce with a plank in the outside of template, and it can achieve the goal equally.Also can offer the nail hole 41 corresponding on the inner side template 4 in advance,, directly adopt latching to fix so that when hanging inner side template 4 with quarter butt hole for nailing 31.
With reference to Fig. 4, be cast-in-place sectional schematic diagram, steel bracket can make two-sided formwork erection form one, but normative operation, disjunctor at the bottom of channel 9 Qu Bi that build out and the canal, good integrity.
