[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Figure 1 This is an elevation view of this embodiment. Figure 2 This is a floor plan of this embodiment, as shown below. Figure 1 and Figure 2 As shown, this embodiment provides a template structure for cleaning and grouting the bottom of concrete columns, including a template body 10, a support structure 20, and a support 30.

[0035] In this embodiment, the template body 10 includes four sides and is a square structure formed by four sets of wooden templates arranged sequentially. The template body 10 is used to enclose the outer perimeter of the concrete column 11; each side of the template body 10 has a hole 100 at its bottom.

[0036] The support structure 20 is set on the outer periphery of the template body 10, including horizontal bars 201 and vertical bars 202. There are multiple vertical bars 202, which are evenly distributed between the horizontal bars 201 and the template body 10. The support 30 is set at the hole 100 and connected to the support structure 20.

[0037] This formwork structure, used for cleaning and grouting the bottom of concrete columns, has holes of a certain size pre-drilled in the main body 10 of the concrete column formwork to clean debris from the bottom of the column. Before pouring concrete, a certain thickness of concrete mortar of the same proportion is poured manually at the holes 100. After pouring, the supports 30 are installed, and then the overall concrete is poured to ensure the construction quality of the joints of the concrete columns and to prevent the phenomenon of rotten roots in the concrete columns.

[0038] As an optional implementation method, such as Figure 3 and Figure 4 As shown, the support 30 includes a first bracket 301 and a second bracket 302. The first bracket 301 is connected to the crossbar 201 via a first connecting component 41; the second bracket 302 is disposed on top of the first bracket 301 and is connected to the crossbar 201 via a second connecting component 42.

[0039] In this embodiment, the first support 301 and the second support 302 have the same structure. Specifically, both the first support 301 and the second support 302 are plate-shaped structures made of steel.

[0040] By setting the support 30 to use the first bracket 301 and the second bracket 302 with the same structure, this support type can be applied to a variety of scenarios, and can be installed horizontally or vertically.

[0041] When in use, the support 30 can be fixed to a concrete or masonry structure by inserting steel nails into the fixing holes. When fixed to a formwork, bolts can be inserted through the bolt holes to fix it, which facilitates the subsequent removal of the formwork.

[0042] In this embodiment, both the first connecting component 41 and the second connecting component 42 include a screw 401 and a nut 402 that can be connected to the screw 401.

[0043] Specifically, the crossbar 201 is provided with a hole structure for the screw 401 to pass through. The screw 401 passes through the hole structure from one side of the crossbar 201 and is then fixed on the other side of the crossbar 201 by a nut 402. In this embodiment, to improve the stability of the connection, nuts 402 are provided on both sides of the hole structure.

[0044] As an optional implementation, the support structure 20 also includes tie bolts 203 and fasteners 204. The crossbar 201 is connected by tie bolts 203 and fixed by fasteners 204. The two sides of the upright 202 are respectively attached to the crossbar 201 and the template body 10.

[0045] This embodiment also provides a construction method for the above-mentioned formwork structure for cleaning and grouting the bottom of concrete columns, including the following steps:

[0046] S1: Reserved holes: During the installation of concrete column formwork, reserved holes are made on each side of the bottom of the formwork body 10.

[0047] Specifically, during the installation of the concrete column formwork, holes 100mm are pre-drilled on the bottom four sides of the interface positions of the formwork body 10. The size of the holes can be set according to the actual construction needs.

[0048] S2: Fix the support structure 20 by placing the upright 202 on the inside, clamping it with the crossbar 201, and then fixing it. During construction, the crossbar 201 is connected by tie bolts 203 and fixed with fasteners 204, which include fasteners and nuts.

[0049] S3: Clean up debris. After the installation of the formwork and steel reinforcement of the first-floor main structure is completed, when rinsing the formwork of the beams and slabs, some formwork debris or other debris will enter the bottom of the formwork with the water flow.

[0050] S4: Secondary rinsing, including using a high-pressure water gun to rinse the concrete joint area; by pre-reserving holes 100 at the bottom of the formwork body 10, it can be ensured that there are no debris or impurities on the contact surface during secondary rinsing.

[0051] S5: Support 30 installation: Before concrete pouring, connect the first support to the crossbar, and adjust the first support to the inner side of the formwork body by adjusting the connecting components. The joints are sealed with waterproof tape.

[0052] During construction, after cleaning the interface, before pouring concrete, weld the first bracket 301 and the screw 401 of the first connecting component 41 together according to the drawings, and pre-install the inner adjusting nut 402 on the screw 401. Use the outer nut 402 and the inner nut 402 to install and fix the first bracket 301 and the screw 401 into the slot of the crossbar 201. Use the nut 402 to level the inner side of the first bracket 301 with the inner side of the template body 10. After leveling, seal the joint with waterproof tape to prevent grout leakage.

[0053] S6: Concrete mortar injection. Before concrete pouring, concrete mortar of the same proportion is injected through the second support at position 302.

[0054] Specifically, after the lower first support 301 is installed and the concealed acceptance is passed, a few minutes before the concrete pouring, concrete mortar of the same proportion is manually injected through the position of the upper second support 302 that is not installed, and the construction quality of the mortar is ensured by observing through the position of the second support 302.

[0055] S7: After the mortar is injected, connect the second support 302 to the crossbar 201, and adjust the second support 302 and the inner side of the template body 10 by adjusting the connecting components. Seal the joint with waterproof tape.

[0056] During construction, after the cement mortar of the same proportion is poured, the upper second bracket 302 and screw rod 401 (the second bracket 302 and the screw rod 401 of the second connecting component 42 are welded together) are installed and fixed into the slot of the crossbar 201. The inner side of the second bracket 302 is leveled with the inner side of the template body 10 by using the nut 402. After leveling, the joint is sealed with waterproof tape to prevent grout leakage.

[0057] S8: Concrete pouring for the frame columns.
