Description

Technical Field

[0001] The utility model belongs to the technical field of concrete structure construction, and specifically relates to a column foot template positioning device. Background Art

[0002] Concrete pouring is an important process in the construction of concrete structures. The accuracy of the formwork before concrete pouring affects the quality of concrete pouring. Quality problems such as formwork expansion, leakage, and misalignment are endless. The columns are the main load-bearing components of the entire structure, and the quality of their concrete pouring needs to be strictly controlled. During the pouring of concrete columns, the phenomenon of leakage at the column foot is particularly significant. Therefore, preventing leakage at the concrete column foot is of great significance to improving the quality of concrete column pouring.

[0003] The traditional method of preventing leakage at the base of concrete columns is to use mortar to seal the leakage at the base of the column. However, this method increases the manpower input and the transportation of mortar is also very cumbersome during the erection of the formwork. The second method is to use L-shaped steel to reinforce the bottom of the column base when supporting the formwork. The L-shaped angle steel is welded into a frame that matches the column formwork structure, and then the angle steel frame is fixed to the preset position of the floor (or bottom plate). The biggest disadvantage of this method is the structural fit between the connection position between the bottom surface of the angle steel and the surface of the floor, and the connection position between the angle steel and the formwork, which is prone to gaps, so leakage will still occur. Utility Model Content

[0004] The utility model aims to solve the problem of slurry leakage at the lower end of a column foot template in the prior art.

[0005] The utility model solves the above problems and adopts the following technical solutions:

[0006] A column base template positioning device includes a fixing member composed of four L-shaped plates, wherein the L-shaped plates are folded from metal sheets, wherein the bottom plate is horizontally arranged, the vertical plates are inclined, the upper ends of the vertical plates are offset outward, and the angle between the vertical plates and the bottom plate has elastic deformation and elastic reset capabilities.

[0007] Compared with the prior art, the utility model adopting the above technical solution has the following beneficial effects:

[0008] The utility model uses four L-shaped plates to form a rectangular frame for positioning the column foot template, and uses an inclined and elastic vertical plate to make the upper part of the vertical plate fit tightly with the column foot template, thereby avoiding gaps at the connection nodes between the positioning device and the column foot template and reducing slurry leakage.

[0009] As a preferred embodiment, a further technical solution of the utility model is:

[0010] After the vertical plate is connected to the column base formwork, the vertical plate is in a vertical state.

[0011] The beneficial effects obtained by the above-mentioned features are as follows: when the vertical plates are vertical, the angle gaps between the vertical plates are closed, thereby achieving complete slurry blocking.

[0012] The lower parts of the sides of the adjacent L-shaped plates are welded and fixed to each other.

[0013] Beneficial effects obtained by the above features: In this example, four L-shaped plates are combined into an integrated frame, which is convenient for installation and does not affect the function of the vertical plate.

[0014] A fixing plate is also arranged outside the four vertical plates, and the four fixing plates are vertically fixed to the bottom plate. A gap is arranged between each fixing plate and the vertical plate, and the width of the gap is adapted to the thickness of the column foot template.

[0015] Beneficial effects obtained by the above features: This embodiment forms a groove for inserting the lower end of the column base template by cooperating with the fixed plate and the vertical plate, so that a U-shaped gap is formed at the lower end of the template. It is difficult for the column concrete to leak to the outside through the U-shaped curved gap, thereby avoiding leakage from the bottom.

[0016] The sides of the four fixing plates are connected to form a rectangular limiting frame.

[0017] Beneficial effects obtained by the above features: In this example, a constraint frame outside the column base formwork is formed by a fixed plate, thereby strengthening the slurry leakage protection at the angle position of the formwork.

[0018] The height of the fixed plate is lower than that of the vertical plate, and the height difference between the fixed plate and the vertical plate is at least the thickness of the column base formwork.

[0019] Beneficial effects obtained by the above features: In this example, the fixed plate and the vertical plate are staggered in height, making it convenient to insert the column foot formwork.

[0020] The lower end of the fixing plate is connected with the bottom plate screws.

[0021] The beneficial effects obtained by the above features are as follows: this embodiment of the fixing scheme can realize component connection, especially when the fixing plate and the base plate are made of different materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention is further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0029] See also Figures 1 to 5 The utility model provides a column foot template positioning device. The design concept is to use elastic materials to press the connection node position components tightly, thereby improving the tightness of the component connection and preventing leakage.

[0030] Specifically, the column base template positioning device includes a fixing part composed of four L-shaped plates, and the L-shaped plates are formed by folding metal sheets, wherein the bottom plate 1 is horizontally arranged, the vertical plate 2 is inclined, and the upper end of the vertical plate 2 is offset to the outside; the material of the metal sheet is elastic, especially the angle formed by the vertical plate 2 and the bottom plate 1 has elastic deformation and elastic reset capabilities.

[0031] After mold closing, the outside of the column base template 8 needs to be fastened with a positioning hoop 9. The column base template 8 is constrained by the positioning hoop 9 and squeezed inward. The vertical plate 2 is pushed up at the least under the lateral pressure of the column base template 8, thereby becoming a vertical state, and the angle gap between each side vertical plate 2 becomes smaller or closed, forming a complete inner layer of leakage-proof protection; at the same time, the vertical plate 2 generates pressure against the column base template 8 under the action of its own elastic force, and the upper part is tightly pressed against the surface of the column base template, thereby avoiding gaps in the nodes where the positioning device is connected to the template and reducing leakage.

[0032] Optionally, the lower parts of the sides of the vertical plates 2 of the adjacent L-shaped plates are welded to each other, so that the ends of the vertical plates 2 are connected; the position of the weld 6 is shown in FIG. Figure 2 As shown, the height of the weld 6 can be set to about one-third of the height of the vertical plate 2, so as to achieve the connection strength without affecting the elasticity of the upper end of the vertical plate 2. This can increase the integrity of the inner layer of the device and reduce deformation.

[0033] See also Figure 4 , Figure 5 The metal sheets used to make the bottom plate 1 and the vertical plate 2 are thin steel plates; the vertical plate 2 is made of thin plates, so that the thickness difference at the position where it is combined with the column foot template 8 is small. After the concrete is poured, only a shallow concrete dent will appear at the bottom of the column, which will not affect the strength of the column.

[0034] Furthermore, a fixing plate 3 is provided on the outer side of the vertical plate 2 , and four fixing plates 3 are vertically fixed to the bottom plate 1 . A gap 5 is provided between each fixing plate 3 and the vertical plate 2 , and the width of the gap 5 is adapted to the thickness of the column base template 8 .

[0035] In order to strengthen the leakage prevention of the angle, the sides of the four fixed plates 3 are connected to form a rectangular limit frame; the four vertical plates 2 constitute a rectangular protection frame on the inside of the column base template 8, and the four fixed plates 3 constitute a protection frame on the outside of the column base template 8. The middle interval 5 forms a rectangular groove for inserting the column base template. When the column base template 8 is installed, the lower end of each side template is inserted into the groove in turn, and a U-shaped slurry stopping structure is formed at the lower end of the column base template 8. It is difficult for concrete slurry to break through the U-shaped bending gap and leak out of the fixed plate 3, and the leakage prevention effect is good.

[0036] Optionally, the height of the fixed plate 3 is lower than that of the vertical plate 2, and the height difference between the fixed plate 3 and the vertical plate 2 is at least the thickness of the column base template 8, so as to facilitate the installation of the column base template 8. During the specific operation, the column base template 8 is slightly tilted, and the lower end of the column base template 8 gently pushes the upper end of the vertical plate 2, and then it can be inserted into the gap 5 along the vertical plate 2.

[0037] The fixing plate 3 is combined with the base plate 1 by screws 4, and is thus simultaneously installed to a predetermined position of the floor slab 7 on the lower side of the column foot. The overall volume is small, and the installation and positioning are convenient, which facilitates the subsequent installation of the column foot formwork 8.

[0038] The floor slab 7 at the lower side of the column foot of the utility model is embedded in the floor slab concrete during pouring, thereby solving the problem of leakage of slurry due to the gap between the positioning device and the floor slab surface. The utility model constructs a U-shaped slurry stopping structure, and the fluidity of the concrete slurry cannot leak to the outside through the U-shaped slurry stopping structure, thereby solving the problem of leakage of slurry at the bottom of the column foot. After the utility model is demolded, the exposed part above the floor slab is cut off, which will not affect the subsequent structural construction.

[0039] The above description is only a preferred feasible embodiment of the present utility model, and does not limit the scope of rights of the present utility model. All equivalent changes made using the contents of the present utility model specification and its drawings are included in the scope of rights of the present utility model.
