Abstract
The utility model relates to ultra-long reinforced concrete construction, in particular to a demolition-free template of a reinforced concrete construction joint with an ultra-long structure, which comprises a steel reinforcement framework which is welded on the reinforced bar of a beam slab, square lumber which closely props against the steel reinforcement framework and is connected with the upper reinforced bar of the beam slab and a steel screen which is fixedly arranged on the steel reinforcement framework. The utility model can tightly hold the concrete and can mix novel concrete and old concrete as a whole without removing the template.
Description
Technical field
The utility model relates to the overlength reinforced concrete construction, relates in particular to a kind of template of super-long structural reinforced concrete construction seam.
Background technology
In the super-long structural reinforced concrete construction, usually need factors such as loading characteristic, concrete supply ability and on-site actual situations according to structure, concrete structure is divided into several portions constructs, at concrete structure vertical construction joints is set, in order to guarantee to combine well with the concrete of pouring next time, vertical construction joints all has protruding bar, and the vertical construction joints surface requirements is a pitted skin.
If the vertical construction joints place installs with wooden model, wooden form is reinforced relatively difficulty, and form removable is also pretty troublesome, and after the wooden model dismounting, also needs to cut a hole hair to the vertical construction joints surface and handle.
Summary of the invention
The utility model is intended to address the above problem, and a kind of non-dismantling formwork of super-long structural reinforced concrete construction seam is provided.The utility model can hang on to concrete, makes new, old concrete coincide into an integral body herein, and template need not removed.
The utility model is achieved in that a kind of non-dismantling formwork of super-long structural reinforced concrete construction seam, it comprises: be welded on the cage of reinforcement on the beam reinforced steel bar, near this cage of reinforcement and be connected the lumps of wood on the beam slab top reinforcement, and be fixed on the expanded metal lath on the cage of reinforcement.
The non-dismantling formwork of described a kind of super-long structural reinforced concrete construction seam, described expanded metal lath comprises two-layer, one deck is the fine mesh expanded metal lath, another layer is for dredging the perforated plate net, the expanded metal lath density interphase, the colligation of two-layered steel plates net is fixed together, adjacent steel plate wire side overlap joint.
The non-dismantling formwork of described a kind of super-long structural reinforced concrete construction seam, described expanded metal lath top with nail wrap up in nail the lumps of wood on, adopt on the steel nail fixing concrete bed course or on the template expanded metal lath bottom.
The non-dismantling formwork of described a kind of super-long structural reinforced concrete construction seam, described cage of reinforcement is made up of vertical reinforcement and horizontal reinforcement, its highly be the below on earth, the top deducts protective layer thickness to the beam slab concrete plate surface.
The utility model mainly is made up of clad steel expanded metals and cage of reinforcement, and the clad steel expanded metals is isolated concrete, cage of reinforcement supporting steel plate net.The interface performance of more conventional plywood form is better: when concrete is built in the template back, concrete grout is penetrated into the interface by expanded metal lath mesh checkerwork cell and forms the very desirable coarse grain interface of a kind of shear behavior, reliably bonding with as placed concrete, fundamentally overcome defectives such as constuction joint is loose.
Secondly, the utility model easy construction, this template is from heavy and light, transportation and easy for installation, the reinforcing bar of interspersed various diameters easily, cutting in the work progress, easy to process.
At last, the utility model can shorten the construction period; This template set-up time was lacked than the time that plywood form is installed.Non-dismantling formwork is stayed in the concrete, has saved the take-down time.
Description of drawings
Below, in conjunction with the accompanying drawings the utility model is further described:
Fig. 1 is the utility model sectional drawing;
Fig. 2 is an A-A sectional view among Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2: a kind of non-dismantling formwork of super-long structural reinforced concrete construction seam, it comprises: be welded on the cage of reinforcement 1 on the beam reinforced steel bar, near this cage of reinforcement 1 and be connected the lumps of wood 3 on the beam slab top reinforcement, and be fixed on the expanded metal lath 2 on the cage of reinforcement 1.
Described cage of reinforcement 1 is made up of vertical reinforcement 5 and horizontal reinforcement 6, its highly for the below on earth, the top deducts protective layer thickness to the beam slab concrete plate surface.
Described expanded metal lath 2 comprises two-layer, and one deck is the fine mesh expanded metal lath, and another layer is thin perforated plate net, the expanded metal lath density interphase, and the colligation of two-layered steel plates net is fixed together, adjacent steel plate wire side overlap joint.
Described expanded metal lath 2 tops with nail wrap up in nail the lumps of wood 3 on, adopt on the steel nail 4 fixing concrete bed courses or on the template expanded metal lath 2 bottoms.
Claims (4)
