Abstract
The utility model discloses a kind of handrail formwork for placing structure of spiral stairs, comprising: an outer arc template, comprise one first panel and be incorporated into the first steel framework of the first panel, outer arc template erection is on the bench pouring structure of spiral stairs; One inner arc template, comprises one second panel and is incorporated into the second steel framework of the second panel, inner arc template erection on ground and relatively outer arc template-setup; Wherein: the bottom of the second panel is formed with one section lower than the first panel and the low level faceplate section concordant with described bench pouring structure, multiple split bolt is equipped with between first panel and the second panel, have at least a split bolt to wear low level faceplate section, and be fixed on the reinforcing bar of bench pouring structure.The split bolt of low level faceplate section, for the problem that there is height fall between outer arc template and the panel of inner arc template, is utilized the reinforcing bar of bench pouring structure to be fixed, thus ensure that the stability of handrail formwork for placing structural base by the utility model.
Description
Technical field
The utility model relates to the formwork structure used in a kind of concreting, espespecially a kind of formwork structure of building for the handrail of spiral stairs.
Background technology
Consult the spiral stairs structure shown in Fig. 1, it comprises spiral bench 10, circular wall 20 and handrail 30; Wherein, this handrail 30 includes an extrados 31 and an intrados 32, and adopts pouring exposed concrete, and therefore at formwork erection, split bolt arranges all there is larger problem, annoyings those skilled in the art always.
Utility model content
The technical problems to be solved in the utility model is to propose a kind of novel spiral stairs handrail formwork for placing structure, and it is set up the difficult point that can overcome and exist in prior art at the cloth of formwork erection and split bolt.
For solving the problems of the technologies described above, the utility model discloses a kind of handrail formwork for placing structure of spiral stairs, comprise: an outer arc template, comprise one first panel and be incorporated into the first steel framework of described first panel, described outer arc template erection is on the bench pouring structure of described spiral stairs; One inner arc template, comprises one second panel and is incorporated into the second steel framework of described second panel, and described inner arc template erection is on ground and relatively described outer arc template-setup; Wherein: the bottom of described second panel is formed with one section lower than described first panel and the low level faceplate section concordant with described bench pouring structure, multiple split bolt is equipped with between described first panel and described second panel, have at least a split bolt to wear described low level faceplate section, and be fixed on the reinforcing bar of described bench pouring structure.
The split bolt of low level faceplate section, for the problem that there is height fall between outer arc template and the panel of inner arc template, is utilized the reinforcing bar of bench pouring structure to be fixed, thus ensure that the stability of handrail formwork for placing structural base by the utility model.
Further improvement of the utility model is that described second steel framework comprises: a panel connection box, connects described second panel, and described panel connection box is formed with the split bolt support back cord vertically extended; One floor-type support frame, is located at the bottom of described panel connection box, is supported on ground.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
Refer to shown in Fig. 2, formwork structure of the present utility model mainly comprises outer arc template 40 and an inner arc template 50, wherein:
Coordinate shown in Fig. 3,5, this outer arc template 40 comprises one first panel 41 further and is incorporated into the first steel framework 42 on the first panel 41, this first steel framework 42 comprises the split bolt that arc back cord 421 and multiple tracks vertically extend and supports back cord 422, supports to be provided with between back cord 422 strengthen back cord 423 at split bolt; This split bolt is supported back cord 422 and the impact that it can be made not to be subject to template arc is vertically set, still straight line is kept to extend, meet the strength and stiffness requirement that split bolt supports back cord, ensure that the stability that split bolt connects, and then improve the seal of spiral stairs handrail template.And split bolt support back cord 422 adopts vertical arc back cord 421 mode to arrange, and facilitates the machining accuracy of steel framework, adopts arc force structure, then the bad guarantee of machining accuracy if complete.After this split bolt support back cord 422 is welded and fixed, support between back cord 422 at split bolt and arrange arc back cord, this arc back cord is also stressed back cord.This outer arc template 40 is set up on the bench pouring structure 60 of spiral stairs, and shores further by a steel pipe jacking 61 on the circular wall 20 that is fixed on and built in advance.
Coordinate shown in Fig. 4,5, this inner arc template 50 comprises one second panel 51 further and is incorporated into the second steel framework 52 on the second panel 51, this second steel framework 52 comprises one for connecting the panel connection box 521 of the second panel 51, and one for being supported in the floor-type support frame 522 on ground; The structure of this panel connection box 521 is basic identical with the first steel framework 42, is formed with arc back cord, and the split bolt that multiple tracks vertically extends supports back cord and strengthens back cord; This floor-type support frame 522 is arranged at the bottom of panel connection box 521, is a rectangular box structure, by it, inner arc template 50 is set up in bottom surface, and shores further by a steel pipe jacking 53 and be fixed in external support system 54.
Consult shown in Fig. 2,5 further, outer arc template 40 and inner arc template 50 are oppositely arranged, centre defines the casting space of this handrail, multiple split bolt 70 is equipped with between the first panel 41 and described second panel 51, wherein the bottom of the second panel 51 is formed with one section lower than described first panel 41 and the low level faceplate section 511 concordant with described bench pouring structure 60, this low level faceplate section 511 is equipped with equally a split bolt 71, and this split bolt 71 is fixedly welded on the reinforcing bar 62 of bench pouring structure 60 after wearing low level faceplate section 511.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make many variations example to the utility model according to the above description.Thus, some details in embodiment should not formed restriction of the present utility model, the utility model by the scope that defines using appended claims as protection domain of the present utility model.
