Abstract
The invention discloses a simple formwork supporting method for a basement bottom plate or top plate post-cast strip, which comprises the following steps: manufacturing a formwork support → manufacturing a water-stop steel plate → welding the formwork support on the bottom surface and the top surface of the water-stop steel plate respectively → connecting the formwork support with bottom ribs and surface ribs → fixing a steel wire mesh on one side of the formwork support → welding and fixing the water-stop steel plate and the bottom ribs by a group of short steel bars → pouring concrete. According to the invention, the formwork support is used for replacing a wood formwork and a wood beam in the prior art to support the formwork, in the concrete pouring process, the formwork support system and the concrete form a whole and are left in the bottom plate in a permanent combination mode, and the formwork support does not need to be dismantled in later construction. Both can guarantee the formwork effect, and the later stage can directly carry out next process, not only is waste utilization but also can practice thrift a large amount of manpowers and man-hour to practice thrift construction cost. The invention can also be expanded and popularized to be applied to the construction joint formwork of the standard layer.
Description
Technical Field
The invention relates to a simple formwork supporting method for a basement bottom plate or top plate post-cast strip, and belongs to the technical field of construction of building post-cast strips.
Background
In the long-term construction practice of basement bottom plate or roof post-cast strip and construction joint, because post-cast strip and construction joint need carry out the formwork when pouring. In the prior art, templates, wood beams and the like are generally adopted for supporting the templates. A large amount of manpower and financial resources are required to be consumed for form removal in the later construction process, operation is not easy to occur during form removal in the later period, and an ideal construction effect cannot be achieved.
Disclosure of Invention
The invention aims to provide a simple formwork supporting method for a basement bottom plate or top plate post-cast strip, which can directly perform the next procedure without dismounting the simple formwork at the later stage, can ensure the construction effect and save the cost, and overcomes the defects of the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention discloses a simple formwork supporting method for a post-cast strip of a bottom plate or a top plate of a basement, which comprises the following steps:
step one, manufacturing a formwork support by using a steel bar leftover material of a construction site;
step two, welding a formwork support on the bottom surface and the top surface of the water stop steel plate respectively;
step three, binding or spot welding a formwork support at the bottom of the water stop steel plate with the bottom rib; binding or spot welding a formwork on the top surface of the water stop steel plate with the gluten;
fixing a steel wire mesh on one side of the formwork support far away from the post-cast strip;
step five, welding and fixing one side of the water stop steel plate and the bottom rib by adopting a group of short steel bars;
and step six, pouring concrete.
In the simple formwork supporting method for the basement bottom plate or top plate post-cast strip, the formwork supporting frame is of a rectangular frame structure, and a group of reinforcing ribs are uniformly distributed in the middle of the formwork supporting frame.
In the simple formwork supporting method for the basement bottom plate or top plate post-cast strip, the distance between the reinforcing ribs is not more than 300 mm.
In the simple formwork supporting method for the basement bottom plate or top plate post-cast strip, the formwork supporting frame is vertically welded in the middle along the length direction of the water stop steel plate.
In the simple formwork supporting method for the basement bottom plate or top plate post-cast strip, the steel wire mesh is a dense mesh steel wire mesh.
In the simple formwork supporting method for the basement bottom plate or top plate post-cast strip, the distance between the short reinforcing steel bars is 1500 mm.
Due to the adoption of the technical scheme, compared with the prior art, the formwork support system has the advantages that the formwork support frame is used for replacing a wood formwork and a wood purlin in the prior art to support the formwork, the formwork support system and the concrete form a whole in the concrete pouring process and are retained in the bottom plate in a permanent-temporary combination mode, and the formwork support frame does not need to be detached in later construction. Both can guarantee the formwork effect, and the later stage can directly carry out next process, not only is waste utilization but also can practice thrift a large amount of manpowers and man-hour to practice thrift construction cost. The invention can also be expanded and popularized to be applied to the construction joint formwork of the standard layer.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
The invention discloses a simple formwork supporting method for a post-cast strip of a bottom plate or a top plate of a basement, which comprises the following steps of: manufacturing a formwork support 1 by using a steel bar leftover material of a construction site → manufacturing a water-stop steel plate 2 by using a steel plate → respectively welding the formwork support 1 on the bottom surface and the top surface of the water-stop steel plate 2 → binding or spot welding the formwork support 1 on the bottom surface of the water-stop steel plate 2 and a bottom rib 3; the formwork support 1 on the top surface of the water stop steel plate 2 is bound with the gluten 4 or is connected through spot welding → the steel wire mesh 6 is fixed on one side of the formwork support 1 far away from the post-pouring belt 5 to prevent the concrete from leaking during pouring, one side of the water stop steel plate 2 and the bottom rib 3 are welded and fixed by adopting a group of short steel bars 7 → the concrete pouring is carried out, and the next construction procedure can be carried out after the concrete reaches the strength required by the construction.
The formwork support 1 is shown in fig. 2, the formwork support 1 is a rectangular frame structure, and a group of reinforcing ribs 8 are uniformly distributed in the middle. The spacing between the reinforcing ribs 8 is not more than 300 mm.
The water stop steel plate 2 is a rectangular steel plate, and two long sides of the rectangle are bent downwards; the formwork support 1 is vertically welded in the middle along the length direction of the water stop steel plate 2; the steel wire mesh 6 is a dense mesh steel wire mesh (normally, a dense mesh steel wire mesh with the diameter of 1 mm-4 mm multiplied by 1 mm-4 mm can be adopted); the distance between the short steel bars 7 is 1500 mm.
In specific implementation, the size of the formwork support 1 is determined according to actual engineering requirements; the distance between the binding points or spot welding points of the support die frame 1, the bottom ribs 3 and the gluten 4 is 200 mm; the short bars 7 have the same diameter as the smallest diameter of the gluten 4.
