Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
The structure of the conventional form hanging template is shown in fig. 1, a conventional template 10 is supported by a template support body 20 arranged at the lower part of the conventional template, and the template support body 20 is fixed on a horizontal ground 30, so that after the conventional template 10 is supported and fixed, structural steel bars are laid on the conventional template, concrete is poured, after the poured concrete is solidified and formed to form an upper concrete floor 40, the template support body 20 and the conventional template 10 are removed according to the above, and the pouring construction of a floor is completed. When the next floor slab is poured, the formwork support body 20 needs to be built again, the traditional formwork 10 is supported, and then the construction process is repeated.
According to the construction method, the formwork support body 20 needs to be built once for formwork support every time pouring construction of one floor slab is completed, the working strength is high, and the occupied time is long; and the traditional template 10 is easy to damage in the repeated dismounting and mounting process, so that the template can not be reused, and the construction cost is increased.
In order to overcome the defects of the prior art, the embodiment of the present invention provides a formwork hanging template of a reverse method, the structure of which is shown in fig. 2 and 3, and the formwork hanging template comprises a template main body 1 and a plurality of first bearing steel bars 4. Two ends of the template main body 1 are symmetrically provided with two grooves 2, the centers of the grooves 2 are provided with upright post holes 3, and during construction operation, the template main body 1 is sleeved outside the upright posts 8 through the upright post holes 3 arranged on the template main body; one end fixed connection of a plurality of first bearing reinforcing bars 4 is on template main part 1, and the other end is used for connecting hoisting equipment. The grooves 2 are provided to form a bearing platform for bearing the floor, also called a cap, at the junction of the concrete floor and the upright column 8 after the concrete is poured.
During construction operation, the upright post 8 is fixedly arranged on the ground, the template main body 1 is sleeved outside the upright post 8, and meanwhile, the template main body 1 is connected with hoisting equipment through a plurality of first bearing reinforcing steel bars 4 arranged on the template main body, namely, the template main body 1 is hung by the hoisting equipment. Sleeving a first sleeve 5 on a first bearing steel bar 4, then, starting to lay structural steel bars on the template main body 1, and then pouring concrete; because the outside cover of a plurality of first bearing reinforcing bars 4 is equipped with first sleeve 5 for concreting not with first bearing reinforcing bar 4 direct contact, like this, pour the back, first sleeve 5 and concreting form an organic whole, and stay in the concrete floor after the shaping, but first bearing reinforcing bar 4 can freely descend in first sleeve 5 is inside. By lowering the position of the hoisting equipment downwards, the template main body 1 is driven to slide along the upright post 8 from top to bottom (from the position A to the position B in the figure), when the template main body 1 descends to the elevation of the next floor slab, the structural steel bars are laid on the template main body 1, the first sleeves 5 are sleeved outside the first bearing steel bars 4 again, then concrete is poured, and the process is repeated to finish the pouring of the next floor slab.
The formwork lifting template of the reverse construction method of the utility model can be fixedly connected to the hoisting equipment through the plurality of first bearing steel bars 4 arranged on the formwork lifting template, and the bent formwork supporting body 20 at the lower part of the formwork main body 1 is not needed; just the utility model discloses a template main part 1 need not to demolish repeatedly in the use, and the stand hole 3 that the accessible set up on it makes it descend along 8 directions successive layers of stand, and pouring of a plurality of floors of top-down's completion can reduce construction cost, improves the efficiency of construction.
Preferably, the formwork hanging template of the reverse construction method of the embodiment further comprises a plurality of second bearing steel bars 6 and a plurality of second sleeves 7, the second sleeves 7 have the same function as the first sleeves 5, one ends of the second bearing steel bars 6 are fixedly connected to the template main body 1, and the other ends of the second bearing steel bars 6 are used for connecting an upper floor slab; the second sleeves 7 are sleeved on the second bearing steel bars 6. The other end of second bearing reinforcing bar 6 can pass through fastener fixed connection on the concrete floor of the last floor of pouring the completion, like this, through add a plurality of second bearing reinforcing bars 6 on template main part 1, can be so that template main part 1 passes through the common bearing of concrete floor of hoisting equipment and last floor, when carrying out next floor concrete floor and pour, the each point atress of template main part 1 is more firm, and the improvement operation security, and do benefit to and improve and pour the quality. After the pouring is finished, the second bearing reinforcing steel bars 6 are disconnected with the upper layer concrete floor slab, and then the position of the hoisting equipment can be lowered down, so that the template main body 1 slides to the elevation of the next layer of floor slab from top to bottom along the upright posts 8, and the next layer of floor slab is poured.
Preferably, the first plurality of load-bearing reinforcing bars 4 are symmetrically and uniformly distributed on the formwork body 1. Like this, can make 1 each point atress of template main part more even, the template hoist and mount is more firm, improves the operation security, promotes and pours the quality.
Preferably, a plurality of second load-bearing rebars 6 are symmetrically and uniformly distributed on the formwork body 1. Therefore, the stress uniformity of each point of the template main body 1 can be further improved, the operation safety is improved, and the pouring quality is improved.
