In addition, the utility model also relates to a construction device including the above-mentioned device for plugging the root of a formwork. Background Art
[0002] When the flatness of the floor slab at the bottom of the on-site concrete column and shear wall is insufficient, there often occurs the phenomenon that the bottom of the formwork of the frame column and shear wall is not tightly plugged or not plugged at all, which will lead to poor quality of the locally formed concrete. In severe cases, there may even be a quality defect of concrete root rot, affecting the overall stress condition of the structure.
[0003] During the construction process, the bottom of the formwork is smooth during concrete construction, while the raft board surface after chiseling treatment is usually uneven. Therefore, there will be a phenomenon that the joint between the bottom of the formwork and the raft board surface is not tight, resulting in the outflow of the root concrete slurry. This phenomenon is called slurry leakage. Slurry leakage will lead to poor quality of the locally formed concrete.
[0004] In summary, how to avoid the occurrence of slurry leakage is an urgent problem to be solved by those skilled in the art at present. Summary of the Utility Model

[0029] A device for plugging the root of a template provided by the present application includes: a matrix 1, an airbag 2 and a gas supply device;
[0030] Among them, the matrix 1 is used to be arranged on the floor slab and form a tubular structure with the floor slab, and one end of the tubular structure is used to abut against the template 3;
[0031] The airbag 2 is arranged inside the tubular structure;
[0032] The gas supply device is connected to the airbag 2 and is used to supply gas to the airbag 2 or extract gas from the airbag 2.
[0033] Specifically, please refer to the attached Figure 2, the base body 1 is arranged on the upper surface of the floor slab and forms a tubular structure with the floor slab. One end of the tubular structure abuts against the formwork 3. An airbag 2 is arranged inside the tubular structure. The airbag 2 is selected as a high-strength elastic airbag similar to that used in the interception of high and low grades of concrete. One side of the formwork 3 abuts against the base body 1, and the other side is used to fit the unfixed concrete. Since one end of the formwork 3 close to the floor slab cannot be fully fitted with the concrete due to bending or other reasons, at this time, it is necessary to control the air supply device to introduce a sufficient amount of gas into the airbag 2. The gas can be selected as air, preferably nitrogen, so as to cooperate with the base body 1 through the inflated airbag 2 to extrude the formwork 3, so that the formwork 3 can be fully fitted with the unfixed concrete, avoiding the occurrence of slurry leakage.
[0034] Optionally, a pressure sensor can be arranged inside the airbag 2, and a display device can be arranged outside the airbag 2, so as to ensure that the formwork 3 can be fully fitted with the concrete under the condition of being extruded by directly observing the internal air pressure value of the airbag 2.
[0035] Optionally, a gasket can be arranged between the airbag 2 and the formwork 3 to prevent the sharp end on the formwork 3 from piercing the airbag 2.
[0036] On the basis of the above embodiment, the base body 1 includes a U-shaped airbag groove 11 and a fixing plate 12. The airbag 2 is arranged in the airbag groove 11, and the fixing plate 12 is connected to the airbag groove 11.
[0037] Specifically, the airbag groove 11 is set as a U-shaped structure, and directly buckling on the floor slab can form a rectangular tubular structure. One end of the airbag groove 11 is connected with a fixing plate 12. Both the airbag groove 11 and the fixing plate 12 are made of angle steel, and the thickness is generally designed to be 3 mm, reducing the overall weight on the premise of ensuring structural stability and improving the convenience of using the device.
[0038] On the basis of the above embodiment, at least two fixing holes 121 are arranged on the fixing plate 12, and the fixing holes 121 are used in cooperation with the positioning device and are used to realize the positioning of the fixing plate 12.
[0039] Specifically, at least two fixing holes 121 are arranged on the fixing plate 12, and the positioning device passes through the two fixing holes 121 respectively, so as to prevent the base body 1 from rotating, and can also ensure structural stability after the airbag 2 is inflated by the air supply device.
[0040] On the basis of the above embodiment, the positioning device is a screw.
[0041] Specifically, the positioning device is generally selected as a screw, and the fixing plate 12 is fixed on the surface of the floor slab through an electric drill bit, which can ensure structural stability.
[0042] Optionally, the positioning device can also be selected as a structure such as a rivet, as long as it can realize the fixation of the base body 1.
[0043] In some embodiments, two fixing plates 12 are provided, and the two fixing plates 12 are respectively connected to two ends of the airbag groove 11.
[0044] Specifically, a fixing plate 12 is provided at each end of the airbag groove 11. Positioning the airbag groove 11 through the two fixing plates 12 can improve the stability during the operation of the device.
[0045] Based on the above embodiments, a demoulding layer is provided on the base body 1, and the demoulding layer is used to reduce the difficulty of disassembling the base body 1.
[0046] Specifically, before fixing the base body 1 to the floor slab, a demoulding agent is applied to the surface of one end of the base body 1 that abuts against the formwork 3 to form a demoulding layer. During the process of disassembling the base body 1 after the concrete in contact with the formwork 3 is set, due to the action of the demoulding agent, it is convenient to take out the device smoothly.
[0047] Based on the above embodiments, a formwork line 111 is provided on the side of the airbag groove 11 facing away from the airbag 2. The formwork line 111 is provided in the middle of the airbag groove 11 and is arranged along the extending direction of the airbag groove 11.
[0048] Specifically, a formwork line 111 is provided in the middle of the side of the airbag groove 11 facing away from the airbag 2. Before installing the base body 1 on the surface of the floor slab, it is necessary to align the formwork line 111 on the airbag groove 11 with the formwork line 111 on the formwork 3 to ensure that the position where the airbag 2 can squeeze the formwork 3 is accurate, and to avoid the position deviation of the force of the airbag 2 on the formwork 3 resulting in slurry leakage.
[0049] The specific usage process of the above device for plugging the root of the formwork is as follows: First, abut the airbag groove 11 and the fixing plate 12 of the device against one side of the formwork 3 and apply a demoulding agent to the upper end surface of the airbag groove 11. Then, overlap the formwork line 111 on the airbag groove 11 with the formwork line 111 on the formwork 3 popped out on site and fix it with screws. Then, inflate the airbag 2 through the air supply device so that the bottom of the airbag 2 is in close contact with the roughened floor slab, thereby eliminating the bottom gap. Then, let the workers carry out the suspended formwork construction of the concrete column. Finally, fix it with square-round fasteners and wooden squares on the outside of the formwork 3, and the installation process of the device can be completed. For the structural schematic diagram of the device after installation, please refer to the appendix Figure 1 .
[0050] In addition to the above device for plugging the root of the formwork, the present utility model also provides a construction equipment including the device for plugging the root of the formwork disclosed in the above embodiments. For the structures of other parts of the construction equipment, please refer to the prior art and will not be elaborated herein.
