For example, the installation and dismantling of formwork involves a large workload, affecting construction efficiency; the formwork material is prone to deformation, leading to unstable PC column forming quality; and the low reusability of formwork increases construction costs. These problems not only hinder the advancement of PC column construction technology but also affect the sustainable development of the construction industry. To overcome the shortcomings of traditional formwork techniques, a modular, tool-type column base grouting formwork is proposed. Summary of the Invention
[0004] To address the problems of existing technologies, this invention provides a modular, standardized column base grouting formwork. This formwork offers advantages such as improved installation and dismantling efficiency and high formwork utilization. It solves the problem of traditional PC column base formwork techniques, which typically use steel or wooden formwork for assembly.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0016] 1. This invention utilizes high-precision steel to manufacture steel formwork, achieving high dimensional accuracy and surface smoothness, thus ensuring the dimensional and aesthetic quality of concrete structures. Compared to traditional wooden formwork, steel formwork has relatively lower procurement costs and higher utilization rates, reducing material costs for construction units. This aligns with sustainable development principles, helping to reduce the consumption of natural resources such as timber and minimizing environmental damage and pollution.

[0026] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0027] The structure of the present invention will now be described in detail with reference to the accompanying drawings.
[0028] like Figures 1 to 6 As shown in the figure, the tool-type standardized column bottom grouting template provided in this embodiment of the invention includes two long templates 1 and two short templates 2. The two long templates 1 and two short templates 2 are engaged by tenon and mortise to form a frame. A first angle steel 4 is fixedly installed on the middle of the outer side of each long template 1, and a second angle steel 5 is fixedly installed on the middle of the outer side of each short template 2.
[0029] In this application, 10mm thick steel formwork is used as the main formwork material. Steel formwork not only has good tensile and compressive strength, but also can withstand large construction loads and pressures, ensuring stability and safety during construction. Simultaneously, steel formwork is corrosion-resistant, has a high reusability rate, and is environmentally friendly, thus extending its service life, increasing turnover rate, and reducing construction costs. Secondly, due to the good rigidity and strength of steel formwork, it ensures a smooth and even surface after concrete pouring, improving construction quality. Compared to traditional materials such as wooden formwork, steel formwork has a relatively low procurement cost, reducing material costs for construction units.
[0030] In this case, the main material selected was two 760mm*80mm*10mm and 530mm*60mm*10mm steel templates spliced together. Common angle steel and cement nails were used to fix the middle of the steel templates to prevent misalignment and eccentricity, optimize the on-site installation process, and improve construction efficiency.
[0031] like Figure 1 , Figure 2 As shown, the frame formed by the long template 1 and the short template 2 is positioned by a cross positioning plate 6, and steel plates 7 are fixedly connected to both sides of the cross positioning plate 6.
[0032] In this application, the steel plate 7 is provided to improve the stability of the cross positioning plate 6.
[0033] like Figure 1 , Figure 2 , Figure 3 As shown, sleeves 8 are fixedly connected at the contact points between the steel plate 7 and the cross positioning plate 6. A first steel block 9 is welded onto each sleeve 8, and a second steel block 10 is welded to both ends of each short template 2.
[0034] In this application, the arrangement of the first steel block 9 and the second steel block 10 facilitates the integration of the cross positioning plate 6, which is fixedly connected to the sleeve 8, with the frame formed by the long template 1 and the short template 2 into a whole, thereby improving the stability of the entire grouting template.
[0035] like Figure 1 , Figure 2 , Figure 3 As shown, bolt holes 14 are provided on both the first steel block 9 and the second steel block 10, and adjacent first steel blocks 9 and second steel blocks 10 are fixedly connected by fixing bolts 11.
[0036] In this application, the installation and disassembly efficiency of the first steel block 9 and the second steel block 10 is improved by setting the fixing bolt 11, thereby increasing the grouting speed.
[0037] like Figure 1 , Figure 4 , Figure 5and Figure 6 As shown, the long template 1 has a first mortise and tenon groove 101 at both ends, and a horizontal slot 102 is provided on the long template 1 on one side of each first mortise and tenon groove 101. The short template 2 has a second mortise and tenon groove 201 at both ends. The long template 1 and the short template 2 are engaged through the first mortise and tenon groove 101 and the second mortise and tenon groove 201.
[0038] In this application, since the grouting height of the PC column base is 50mm, the length is 650mm, and the width is 450mm, grooves are made on both sides of the steel formwork. The height of the first tenon groove 101 on both sides of the 760mm*80mm*10mm long formwork 1 is 40mm, and the height of the second tenon groove 201 on both sides of the 530mm*60mm*10mm short formwork 2 is 20mm. Since the height of the short formwork 2 is 60mm, the height difference between the grouting height of the PC column base and the height of the short formwork 2 is 10mm. This 10mm height difference is used for vertical leveling, so that the grouted concrete has sufficient height difference for leveling the horizontal surface. The setting of the horizontal groove 102 facilitates the horizontal leveling of the short formwork 2.
[0039] like Figure 1 , Figure 2 , Figure 4 As shown, each horizontal slot 102 is equipped with a horizontal adjustment steel block 3 for adjusting the levelness.
[0040] In this application, by inserting the horizontal adjustment steel block 3 into the horizontal slot 102, the short template 2 is horizontally adjusted under the action of the inner plane of the horizontal adjustment steel block 3, thereby improving the stability of the steel template frame and avoiding positional displacement during grouting, which could lead to errors in the finished grouting product.
[0041] like Figure 1 , Figure 2 , Figure 4 As shown, the height of the first angle steel 4 is the same as the height of the long template 1, and the height of the second angle steel 5 is the same as the height of the short template 2.
[0042] In this application, the placement of the first angle steel 4 and the second angle steel 5 facilitates the positioning of the steel formwork and improves construction efficiency.
[0043] like Figure 1 , Figure 2 , Figure 4 As shown, both the first angle steel 4 and the second angle steel 5 have two cement nail holes 12 for fixing the angle steel, and both the first angle steel 4 and the second angle steel 5 have holes 13.
[0044] In this application, the cement nail hole 12 is provided to facilitate the fixing of the cement nail to the steel formwork frame by angle steel. After the grouting is completed, the hole 13 is provided so that the cement nail can be pried up by inserting steel bars through the hole 13, so as to achieve the effect of quick demolding and quick turnover.
[0045] Working principle of the invention:
[0046] First, the cross lines of the pre-installed PC columns are pre-drawn according to the raft slab grid to ensure the accuracy of the PC column positions. Then, four steel templates are connected into a frame by combining the first tenon groove 101 and the second tenon groove 201, so that the steel template frame covers the bottom cross lines of the PC column. Then, each horizontal adjustment steel block 3 is inserted into each horizontal slot 102 to ensure the levelness of the short template 2. Then, the first angle steel 4 and the second angle steel 5 are fixed with cement nails to prevent the steel template frame from being misaligned or eccentric, so as to improve construction efficiency.
[0047] Then, using the pre-drawn cross lines at the bottom of the PC column, place the cross positioning plate 6 inside the steel formwork frame, so that the four corners of the cross positioning plate 6 abut against the four corners inside the steel formwork frame, and then weld the steel plate 7 onto the cross positioning plate 6.
[0048] Before drilling, the PC column area should be leveled and checked according to the elevation. The hole depth should not be determined directly by the ground to avoid the anchor bolts being exposed too long or too short after installation. Then, drill holes according to the cross lines drawn on the bottom of the PC column. At the location where holes need to be drilled, weld the sleeve 8 with an outer diameter of 42mm and an inner diameter of 28mm to the steel plate 7 to form a whole and ensure the position of the hole.
[0049] After the hole is drilled, use a blower to blow out the dust and other debris in the hole to ensure that there is no debris in the hole. Insert the matching chemical agent into the hole 13 to anchor to a depth of 220mm. Then, insert the anchor bolt. After insertion, the chemical anchor bolt should be left to stand for a period of time and should not be bumped to avoid loosening.
[0050] After the PC column has solidified, it is installed. The anchor bolts should be inserted as the PC column is installed and protected to prevent deformation from collisions with external objects. After the PC column is installed, the bottom is grouted. After the bottom of the column has solidified, steel bars are inserted into the cavity 13 to pry up the cement nails, thereby achieving the effect of quick demolding and quick turnover.
[0051] In summary, this modular column base grouting formwork, made from high-precision steel, boasts high dimensional accuracy and surface smoothness, ensuring the dimensional and aesthetic quality of the concrete structure. Compared to traditional wooden formwork, steel formwork offers lower procurement costs and higher utilization rates, reducing material costs for construction units. This aligns with sustainable development principles, reducing the consumption of natural resources like timber and minimizing environmental damage and pollution. After special treatment, the steel formwork exhibits excellent corrosion and wear resistance, reducing maintenance costs. Furthermore, its superior tensile and compressive strength allows it to withstand significant construction loads and pressures, ensuring smooth construction. The process ensures stability and safety; the standardized connection methods and auxiliary tools used in the steel formwork installation process improve installation accuracy and construction efficiency, reducing the impact of installation errors on structural accuracy; modern steel formwork calibration and testing equipment enables integrated operation, quickly and accurately completing formwork calibration and testing, further improving construction accuracy and quality control; by drawing on the characteristics of traditional Chinese mortise and tenon structures in the design, and combining the design drawings with the actual construction requirements of the construction site, the PC column base formwork is further designed, reducing the need for many auxiliary tools and equipment during installation and dismantling, thus lowering the difficulty of installation and dismantling; secondly, the formwork uses uniform dimensions and specifications, facilitating assembly and dismantling, and improving construction efficiency.
