Abstract
A rapid assembly connecting structure for alternation of big formwork belongs to the assembly connecting technology of concrete big formwork in the building field. The utility model is a new connecting structure aiming at the common fault of alternation of board and realizing rapid assembly. By adopting an elliptoid-column type connecting bolt and an elliptoid bolt hole matched with the bolt, the utility model realizes the connection of the formwork and overcomes the alternation problem; the utility model realizes rapid assembly and disassembly by adopting the T-shaped structure of the connecting bolt and the connecting mode of straight insert into the bolt hole. During the assembling operation of the formwork, rotates the connecting bolt in 90 degrees and finishes the location of the board surface and the firmness of the connection. The utility model can not only be suitable for big formwork of whole steel, but also be suitable for other construction formworks that take the steel as frame.
Description
One, affiliated technical field
The utility model is a kind of large form composite assembly technology that is used for building engineering field.Be to be prone to the wrong flat problem of plate face and to realize the new Joining Structure of loading and unloading fast at solving the template assembling.By this structure, not only can fundamentally solve the wrong flat problem in the template assembling fully, further improve workmanship; And realized that template assembles fast, and make assembly unit and dismounting simpler, more convenient, can increase work efficiency greatly, accelerating construction progress, reduction engineering cost.
The utility model is not only applicable to all steel large form of all size shape, and to can be used for the steel be other construction formworks of frame.
Two, background technology
In the construction work concrete construction, because that the steel large form has a speed of application is fast, advantages such as good engineering quality are subjected to the generally approval and the extensive use of industry.But in recent years owing to high praise to the clear water concrete project, to improving constantly of workmanship standard and construction efficiency requirement, large form exists bothersome effort and is difficult to overcome in composite assembly the uneven common fault of plate face dislocation has become a great problem of mould plate technique and the technical bottleneck that further improves workmanship.
Large form combination at present all is to adopt plain bolt to assemble, conveniently make bolt pack into easily and withdraw from order to install and remove, the diameter that require to connect the connecting bolt hole on the floor than the big 2mm of the used diameter of bolt about (hole of general drill diameter 18mm is with the bolt of diameter 16mm).Because the difference of keyhole and tightening latch diameter makes template assembling back be difficult to guarantee the smooth of opposite joint both sides adjacent panels face, 2mm even bigger mistake flat (as Fig. 1, Fig. 2) often occur; And when assembly and disassembly, taking a lot of trouble effort, the trivial operations work efficiency is low.
Three, summary of the invention
1, the problem that will solve
The purpose of this utility model provides the flat assembling fast of a kind of large form mistake proofing syndeton.The problem that solves is: fundamentally overcome and be prone to the wrong flat problem of plate face in the large form composite assembly, guarantee that it faces the smooth of plate face mutually; The operation that simplifies the operation is increased work efficiency, and realizes the quick assembling of template.
2, technical scheme
The technical scheme that the utility model adopted is:
(1), the bolt hole on the template fillet rib is done ovalisation (or like oval), the minor axis of elliptical aperture is perpendicular to the plate face of template, and equates that with the major axis dimension of used ellipse tightening latch the major axis in hole is 1.6-2.0 a times of minor axis.(as Fig. 3)
(2), for solving the wrong flat problem of template plate face, the tightening latch (no thread part) of connecting bolt is made oval column type, require long axis of ellipse to equal the minor axis of keyhole, the minor axis of bolt is than the few 2-3mm of major axis, and the length of its cylindroid part is equal to or less than the thickness of 2 floors that connected.(as Fig. 3, Fig. 4)
(3), realize quick dispatch for the operation that simplifies the operation.Connecting bolt is made the T type, and T connector also is oval column type, for guaranteeing to pack into smoothly and withdraw from keyhole, require the long and short axle of oval head to lack 2-4mm than the long and short axle of keyhole respectively, and minor axis equates with the minor axis length of bar portion.The connecting bolt direct inverse is inserted keyhole to the end with T type oval head during the template assembling, and Rotate Right can be finished location and fastening again.
(4) for ease of processing ease bolt is screwed, can 2 symmetrical corner angle edges be screwed the little inclined-plane that direction is made 2 * 3mm at the root of bolt T connector.
3, beneficial effect
The utlity model has following beneficial effect:
The wrong flat problem of the plate face that has been prone to when (1) fundamentally having solved the form assembly assembly unit can guarantee fully that template opposite joint both sides face the smooth of plate face mutually, makes the total quality of template improve a class.
(2) changed traditional operating habit, made the assembly and disassembly of template simpler, more convenient.Only need connecting bolt is carried out the rotation of 90 degree, can finish the assembly and disassembly of template.Compare the raising work efficiency with current way more than 5 times, can accelerate the turnaround speed of template greatly and reduce engineering cost.
(3) rational in infrastructure, simple and reliable, low, the easy enforcement of cost, comparing with existing way does not increase new parts, does not need additionally to increase expense substantially.
(4) widely applicable, be not only applicable to all steel large form, and to can be used for various be other construction formworks of frame with the steel.

Five specific embodiment
The all steel large form commonly used with construction work is example, and its limit rib is generally the band steel of 80*8.Its way is: will connect keyhole and make the ellipse that long and short axle is respectively 33mm and 18mm.Connecting bolt is a T shape, and its T shape head is divided into the oval column type that major and minor axis is respectively 30mm and 15mm, height 10mm; The no silk of tightening latch is respectively the oval column type of 18mm and 15mm for long and short axle partly, and the length of oval part is 15mm.Thread part is M16, length 25mm.(as Fig. 5)
During the template assembling, connecting bolt revolves withdrawing nut (after accent is turned round when using for the first time usually, not needing again moving during repeated use) at the Shi Buxu that packs into.Can be directly insert keyhole from an end of T shape oval head, nut be clamped with spanner in the back, with special spanner the oval head right side of bolt is turn 90 degrees and can finish location and fastening (as Fig. 6-8).During the template dismounting, only need T shape oval head Rotate Left, can move back and get bolt template dismounting (as Fig. 9-11) with connecting bolt.
This utility model not only can solve the wrong flat problem of the plate face that is difficult to overcome fully, and has changed traditional operating habit, has simplified operational sequence, has improved work greatly and has imitated.
