Abstract
The utility model discloses a separate-assembly formwork structure at an interlayer outer wall construction joint. The separate-assembly formwork structure comprises an inner side formwork and an outer side formwork which are arranged on the side portions of a concrete outer wall body to be poured in a supporting mode. The elevation of the outer side formwork is lower than the elevation of a concrete building plate top plate according to a preset value. A fixed formwork with the width larger than the preset value is placed along the horizontal full length of an upper opening of the outer side formwork. The fixed formwork is fastened on the poured concrete outer wall body through a pre-buried piece. According to the separate-assembly formwork structure at the interlayer outer wall construction joint, when upper layer concrete and lower layer concrete are poured, the fixed formwork always maintains the original position, seamless combining of the fixed formwork and the concrete wall body is guaranteed, mortar leakage and slab faulting are avoided, the fixed formwork is arranged in a supporting mode, so that the foundation which can be attached is provided for supporting of other formworks of an outer wall, operation is convenient, after the formworks are disassembled, an upper layer joint and a lower layer joint are tight, mortar is in satiation, perception quality is good, and outer wall decorating construction can be directly carried out.
Description
Technical field
The utility model, about a kind of formwork structure, refers in particular to the loose formwork structure of spelling in a kind of interlayer external wall construction seam place.
Background technology
Concrete structure mainly consists of reinforcing bar, template, the large subitem of concrete three, and wherein, form work engineering is the most complicated, a work items of amount of labour used maximum, and it has become the key factor that affects workmanship, programming.Although widely popularize now typing masterplate, all-steel big shuttering etc., various other new type formworks are also in continuous appearance,, loosely spell that template is low with its cost, convenient transportation, the assembled characteristics such as flexibly be still in occupation of most of market.Yet, along with the workmanship requirement is more and more higher, the shortcomings such as its piece, spillage, faulting of slab ends, distortion are also more and more obvious, not only affect structural safety and presentation quality, also can increase very large post-processed expense, affect carrying out of various work.Especially the thin section at interlayer external wall construction seam place processes, and the spillage that piece does not sternly cause and faulting of slab ends are puzzlement people's a difficult problem for a long time always.Once spillage and faulting of slab ends phenomenon occur, deal with very trouble, the effort of taking a lot of work is more expensive, processes not in time impact image again.
Therefore, each unit actively takes different measures to carry out pre-control, as: the people is arranged at outer wall template bottom pad one elongated flitch, the method can reduce spillage, but the faulting of slab ends phenomenon usually occurs; Someone sets up sponge strip at exterior wall, and the method is had relatively high expectations to complete concrete wall outer edge glacing flatness, otherwise can't jam-packed, still there will be the phenomenons such as spillage and faulting of slab ends; Someone adds a timber wedge in the keel place each time in the wall form bottom, makes the adjacent body of wall of template, the method, and the timber waste is large, and can the pair cross-section size exert an influence; Similar method is a lot, differ and with, but all can't guarantee template and complete concrete wall close contact, thereby tackle the problem at its root.
The utility model content
Because the problems referred to above, the utility model provides a kind of interlayer external wall construction seam place the loose formwork structure of spelling, comprise inner side template and an outboard template of being located at the concrete exterior wall body of wall sidepiece of building to be poured, the absolute altitude of described outboard template is the absolute altitude lower than the concrete floor top board by a preset value, be placed with along described outboard template horizontal full-length suitable for reading the fixed form that a width is greater than described preset value, and described fixed form is anchored on the concrete exterior wall body of wall after having built by a built-in fitting.
Further improvement of the utility model is, described built-in fitting is a pre embedded bolt, one end of described pre embedded bolt wears into concrete exterior wall body of wall to be built, and the other end of described pre embedded bolt stretches out concrete exterior wall body of wall to be built, and further through described fixed form.
Further improvement of the utility model is, the end that described pre embedded bolt wears into concrete exterior wall body of wall to be built is welded with a vertical reinforcing bar.
Adopt the loose template of spelling in interlayer external wall construction seam of the present utility model place, after having built concrete, do not remove fixed form and pre embedded bolt, only remove the template of remainder, the vertical reinforcing bar of pre embedded bolt can form a mutual grasp with concrete, guarantee template firmly.When installing the upper strata outboard template, take fixed form and joined mould as basis in its bottom, and its top is configured by above-mentioned same method, then by the size through calculative determination and spacing configuration secondary joist, main joist and reinforced, check etc.After upper strata concreting completes, then remove the fixed form of outboard template bottom, upper strata, and excise the pre embedded bolt that stretches out exterior wall simultaneously, so repeat construction, complete the construction of whole exterior wall.
The utility model, owing to having adopted technique scheme, has following beneficial effect:
1, due in building the concrete process of levels, fixed form remains that original position is motionless, has guaranteed the seamless combination of itself and concrete wall, avoids occurring spillage and faulting of slab ends phenomenon.
2,, owing to having installed fixed form, what make exterior wall other parts template has installed the basis depended on, convenient operation.
3, exceed the absolute altitude of floor top board due to fixed form, facilitated inspection and the check of glacing flatness and the sectional dimension of outboard template.
4, after form removable, the levels seam is tight, and mortar is full, and organoleptic quality is good, can directly carry out the decoration of exterior wall construction.
The accompanying drawing explanation
Fig. 1 is the loose configuration schematic diagram of spelling the fixed form of formwork structure in interlayer external wall construction seam of the present utility model place.
Fig. 2 is the loose configuration schematic diagram of spelling the pre embedded bolt of formwork structure in interlayer external wall construction seam of the present utility model place.
