Examples
An inflatable concrete formwork assembly is shown in fig. 2-9 and is formed by combining an inflatable formwork 1, a supporting and connecting crossbeam 2, a supporting and connecting crossbeam mounting hoop 3, a right-angle connecting column 4, a parallel connecting column 5, a fixing pile 8 and a connecting arm 9.
The inflatable template 1, the supporting and connecting beam 2, the supporting and connecting beam mounting hoop 3, the right-angle connecting column 4 and the parallel connecting column 5 are core components. The supporting connecting beam mounting hoop 3 and the inflation and deflation valve 7 are accessory parts of the inflatable template 1 and are fixedly mounted on the inflatable template 1.
The inflatable template 1 adopts PVC wiredrawing cloth as a template main body material, and a wiredrawing structure 15 is arranged in the inner space of the template and connected with the opposite template surface layer. The inflatable template using the PVC wiredrawing cloth has the advantages of high local hardness and high overall strength of the inflatable template, and can keep the inflatable template straight and high straightness.
The supporting and connecting beam 2 is made of hollow metal, and the supporting and connecting beam mounting hoop 3 and the supporting and connecting beam mounting hoop bottom plate 16 are made of PVC material with certain elasticity. The support connecting beam mounting hoop 3 and the support connecting beam mounting hoop bottom plate 16 are overlapped in an adhesive mode, and are bonded with the PVC layer 14 on the surface of the inflatable template 1 in the same adhesive mode. As shown in fig. 6 and 8, the bottom plate 16 of the support connecting beam mounting hoop is a structure with two straight ends and a concave middle under the state of being not filled with air, the concave and the arc-shaped space of the support connecting beam mounting hoop 3 jointly form an insertion hole of the support connecting beam 2, and under the state of not being filled with air, the hole and the support connecting beam 2 have slight spaciousness, so that the support connecting beam 2 is easy to mount. When the inflatable template is inflated, as the internal pressure of the inflatable template is increased, the concave part of the supporting and connecting beam mounting hoop bottom plate 16 bonded on the surface of the inflatable template is gradually flattened under the action of tensile force generated by tightening the surface of the template under the pressure of the template, and the supporting and connecting beam mounting hoop 3 and the supporting and connecting beam mounting hoop bottom plate 16 are stressed to deform, so that the supporting and connecting beam 2 is clamped, the supporting and connecting beam 2 is tightly connected with the inflatable template 1, as shown in fig. 7 and 9, and the connection and the fixation between the templates are realized.
The right-angle connecting column 4 is formed by connecting two connecting plates 4-1, is a metal cylinder with a 90-degree radial cross section and a surface coated with PVC materials, and is provided with a supporting and connecting beam jack 6. The right-angle connecting column 4 is used for 90-degree connection of the inflatable template, is arranged at the 90-degree connection position of the template when in use, and is connected and fixed with the inflatable template through the supporting connecting beam 2 and the supporting connecting beam jack 6 so as to play roles of connecting and fixing, plugging a gap and fixing a position.
The parallel connecting column 5 is formed by connecting a flat plate 5-1 and a supporting plate 5-2, is a metal cylinder with a T-shaped radial section and a PVC material coated on the surface, and is provided with a supporting and connecting beam jack 6 on the supporting plate 5-2. The parallel connecting columns 5 are used for parallel connection of the inflatable formworks 1. When in use, the supporting plate 5-2 provided with the supporting connecting beam insertion hole 6 is clamped between the two inflatable templates, and the other surface is a flat plate 5-1 which is arranged in the pouring space and is tightly attached to the surfaces of the templates. Because the distance between the supporting and connecting beam and the flat plate 5-1 is less than the thickness of the inflatable template 1, the template can be clamped by the supporting and connecting beam 2 and the flat plate 5-1 after inflation, so that the effects of connecting, fixing, blocking gaps and fixing positions are achieved.
The fixing pile 8 is of a right-angle frame structure, a supporting and connecting beam connector 10 is arranged at the end part of one side, connected with the template, of the fixing pile, and the supporting and connecting beam connector 10 is mutually independent from the template and is fixedly connected with the fixing pile in an adhesive mode; the two ends of one side of the floor contact with the ground are provided with ground nail jacks for inserting ground nails 12, and the middle of the floor contact with the ground is provided with a hinge connecting shaft for connecting the template connecting arm 9. The connecting arm is square tube structure, and its one end is connected one through pivot structure 11 and is connected crossbeam connector 10 with the independent support of inflatable forms 1 mutually, and the other end is equipped with the hinge connecting axle and is used for connecting spud pile 8. The support connector beam connectors described herein are structurally identical to the support connector beam mounting hoops and support connector beam mounting hoop base plates, but are not bonded to the formwork surfaces. When the inflatable connecting device is used, the template upper support connecting beam 2 is inserted into the connector of the connecting arm 9 before inflation, and the template lower support connecting beam 2 is inserted into the connector of the fixing pile 8. When the air inflation device is used for inflating, the connector automatically clamps and supports the connecting beam 2 along with the increase of the air pressure in the template. After clamping, the connecting arm 9 is connected with the fixing pile 8, and the ground nail 12 is inserted into the ground nail inserting hole 13 to stably connect the fixing pile with the ground.
When not in use, the interior of the inflatable template 1 is in an airless state and can be folded or rolled up to reduce the volume.
When the inflatable template is used, the inflatable template 1 is unfolded, and the supporting connecting beam is inserted into the supporting connecting beam mounting hoop, the supporting connecting beam connector and the supporting connecting beam jack in an internal airless state.
And after the beam is installed, an external inflation tool is used for inflating the inflation template through the inflation and deflation valve. In the inflation process, along with the increase of the air pressure in the inflatable template, the support connecting beam mounting hoop, the support connecting beam connector and the support connecting beam jack are inflated and expanded along with the template to automatically clamp the beam, so that the inflatable template, the right-angle and parallel connecting columns, the fixing piles, the connecting arms and the ground are connected and fixed.
And after the inflation is finished, the interior of the inflatable template is in a full-air state, the inflation and deflation valve is closed at the moment, and the concrete is poured.
Because the PVC material has the characteristic of not sticking to concrete, a concrete isolating agent does not need to be coated on the surface of the template to assist demoulding, and the condition that the concrete is damaged by demoulding is reduced.
And (3) when the concrete is poured and molded until the standard of the template removal is reached, opening an air charging and discharging valve of the inflatable template for air discharging, removing the supporting cross beam, the connecting arm, the fixing pile and the connecting column after the mounting hoop is loosened, and then removing the inflatable template in an internal air-free state from the concrete.
Because the PVC material has the characteristics of non-sticking to concrete and corrosion resistance, the template does not need to be subjected to complex cleaning and maintenance operations after being used. And finally, folding and rolling the inflatable template in an internal airless state, and finishing construction.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
