Description

Technical Field

[0001] This utility model relates to the field of template technology, and in particular to a pre-drilled hole template for building civil engineering construction. Background Technology

[0002] Pre-formed hole templates are specialized molds used in building construction to pre-form holes in concrete components (such as walls, floor slabs, beams, and columns). They are typically made of metal, plastic, or wood, and their shape and size are customized according to the hole specifications required by the design. Common shapes include circular, square, or irregular structures. Structurally, pre-formed hole templates generally include the template body, reinforcing frames, and connecting components. The template body forms the surface for the holes, the reinforcing frames enhance the overall rigidity of the template, and the connecting components are used to fix the template to the main template (such as wall templates or floor slab templates).

[0003] Existing pre-drilled hole templates have significant shortcomings in terms of ease of installation, making them unsuitable for efficient construction. Currently, most pre-drilled hole templates are fixed to the main template using bolt connections. Installation requires first lifting the template body to a preset position, precisely aligning the threaded holes on the template with the through holes on the main template, and then tightening the bolts through the through holes and threaded holes. This installation method demands a high degree of teamwork, and the bolt connection process is cumbersome, especially in high-altitude operations or confined spaces. Personnel supporting the template must maintain a fixed posture for extended periods, resulting in high labor intensity. Furthermore, if the bolts become stuck during tightening, the template position must be repeatedly adjusted, further extending the installation time. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a pre-drilled hole template for building civil engineering construction, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a pre-drilled hole template for building construction, comprising several main templates connected end to end. Two corresponding connecting rods are inserted into one side of each main template, and an assembly ring is fixedly connected between the two connecting rods. One side of the assembly ring is in contact with the main template, and several symmetrically arranged positioning pins are fixedly connected to the side of the assembly ring away from the connecting rods. A pre-drilled hole template body is slidably connected between the positioning pins. The side of the pre-drilled hole template body closest to the main template is in contact with the assembly ring. A locking plate is fixedly connected to the inner wall of the pre-drilled hole template body, and two symmetrically arranged locking bolts are rotatably connected to one side of the main template. The threaded portions of the two locking bolts are threadedly connected to the locking plate.

[0007] Preferably, one side of the main template has two corresponding connecting holes, and both connecting rods are slidably connected to the main template through the connecting holes.

[0008] Preferably, one side of the locking plate has two symmetrically arranged threaded holes, and the screw portions of the two locking bolts are threadedly connected to the locking plate through the threaded holes.

[0009] Preferably, one side of the pre-drilled hole template body has two symmetrically arranged positioning holes, and the pre-drilled hole template body is slidably connected to the positioning pin through the positioning holes.

[0010] Preferably, in any of the above solutions, a sealing groove is provided on the side of the pre-drilled hole template body near the main template, and a sealing gasket is fixedly connected to the side of the assembly ring away from the main template. The sealing gasket is slidably connected to the pre-drilled hole template body through the sealing groove.

[0011] Preferably, in any of the above schemes, the inner wall of the pre-drilled hole template body is fixedly connected to two symmetrically arranged support plates, and both support plates are welded together with the locking plate.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. During installation, first insert the connecting rod into the main template through the connecting hole, ensuring the assembly ring fits snugly against the main template. Then, slide the pre-drilled hole template body into the positioning pin through the positioning hole, allowing the sealing gasket to embed into the sealing groove. At this point, the locking plate aligns with the locking bolt on the main template. Finally, rotate the locking bolt to tighten it through the threaded hole and lock it to the locking plate, completing the installation. Positioning, alignment, and fixing can be completed by a single person, eliminating the need for multiple people to lift it. The cooperation between the positioning pin and the positioning hole enables rapid positioning of the pre-drilled hole template body, avoiding repeated alignment adjustments. The connection method between the locking bolt and the threaded hole simplifies the fixing process, reduces installation time, and significantly reduces the labor intensity of construction workers, especially in high-altitude or confined spaces, thereby improving construction efficiency.

[0013] 2. During assembly, the sealing gasket is embedded into the sealing groove along with the main body of the pre-drilled hole template, forming a sealed structure; the welding of the support plate and the locking plate enhances the strength of the locking part; the connecting rod connects to the main template through the connecting hole, and with the support of the assembly ring, the overall structure is subjected to uniform stress. The cooperation between the sealing gasket and the sealing groove effectively prevents grout leakage during concrete pouring, ensuring the forming quality of the pre-drilled hole; the support plate improves the load-bearing capacity of the locking plate, preventing excessive stress on the locking bolts and resulting deformation; the synergistic effect of the connecting rod and the assembly ring enhances the connection stability between the main body of the pre-drilled hole template and the main template, preventing template displacement during pouring and ensuring accurate pre-drilled hole dimensions.

[0016] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0017] like Figures 1 to 5 As shown, a pre-drilled hole template for building construction includes several main templates 1 connected end to end. Two corresponding connecting rods 2 are inserted into one side of each main template 1. An assembly ring 3 is fixedly connected between the two connecting rods 2. One side of the assembly ring 3 is in contact with the main template 1. Several symmetrically arranged positioning pins 4 are fixedly connected to the side of the assembly ring 3 away from the connecting rods 2. A pre-drilled hole template body 5 is slidably connected between the positioning pins 4. The side of the pre-drilled hole template body 5 closest to the main template 1 is in contact with the assembly ring 3. A locking plate 6 is fixedly connected to the inner wall of the pre-drilled hole template body 5. Two symmetrically arranged locking bolts 7 are rotatably connected to one side of the main template 1. The threaded parts of the two locking bolts 7 are threadedly connected to the locking plate 6.

[0018] As an optional technical solution of this utility model, two corresponding connecting holes 8 are opened through one side of the main template 1. Both connecting rods 2 are slidably connected to the main template 1 through the connecting holes 8. The connecting holes 8 on one side of the main template 1 provide a sliding channel for the connecting rods 2, so that the connecting rods 2 can be stably inserted into the main template 1 and drive the assembly ring 3 to fit with the main template 1. This not only ensures the installation accuracy of the assembly ring 3, but also provides a basic support for the positioning of the subsequent pre-drilled hole template body 5. At the same time, the sliding connection facilitates the disassembly and adjustment of the connecting rods 2.

[0019] As an optional technical solution of this utility model, two symmetrically arranged threaded holes 9 are provided on one side of the locking plate 6. The screws of the two locking bolts 7 are threadedly connected to the locking plate 6 through the threaded holes 9. The threaded holes 9 on the locking plate 6 cooperate with the locking bolts 7, and the locking plate 6 and the main template 1 are firmly fixed by the threaded connection, ensuring that the main body 5 of the pre-reserved hole template will not loosen due to concrete impact or vibration during construction. At the same time, the threaded connection method facilitates quick disassembly and assembly, improving the reusability and maintenance convenience of the template.

[0020] As an optional technical solution of this utility model, two symmetrically arranged positioning holes 10 are provided on one side of the pre-drilled hole template body 5. The pre-drilled hole template body 5 is slidably connected to the positioning pin 4 through the positioning holes 10. The positioning hole 10 on one side of the pre-drilled hole template body 5 is slidably connected to the positioning pin 4, which can guide the pre-drilled hole template body 5 to accurately align with the assembly ring 3 during installation, avoid deviation in installation position, ensure the accuracy of pre-drilled hole forming, and at the same time reduce the alignment adjustment time and improve installation efficiency.

[0021] As an optional technical solution of this utility model, a sealing groove 11 is provided on the side of the pre-reserved hole template body 5 near the main template 1, and a sealing gasket 12 is fixedly connected on the side of the assembly ring 3 away from the main template 1. The sealing gasket 12 is slidably connected to the pre-reserved hole template body 5 through the sealing groove 11. The sealing groove 11 of the pre-reserved hole template body 5 and the sealing gasket 12 of the assembly ring 3 cooperate to form a sealing barrier at the connection between the two, preventing the grout from leaking from the gap during concrete pouring, avoiding burrs or deformation at the edge of the pre-reserved hole, and ensuring the construction quality of the pre-reserved hole.

[0022] As an optional technical solution of this utility model, the inner wall of the pre-drilled hole template body 5 is fixedly connected with two symmetrically arranged support plates 13. Both support plates 13 are welded together with the locking plate 6. Welding the support plates 13 on the inner wall of the pre-drilled hole template body 5 to the locking plate 6 can enhance the structural strength and load-bearing capacity of the locking plate 6, prevent the locking plate 6 from bending and deforming under the tightening of the locking bolts 7 or the action of concrete pressure, and ensure the stability and service life of the locking structure.

[0023] A pre-drilled hole formwork for building civil engineering construction, the working principle of which is as follows: 1): During installation, first insert the connecting rod 2 into the main template 1 through the connecting hole 8, so that the assembly ring 3 fits into the main template 1.

[0024] 2): Slide the pre-drilled hole template body 5 into the positioning pin 4 through the positioning hole 10, so that the sealing gasket 12 is embedded in the sealing groove 11. At this time, the locking plate 6 is aligned with the locking bolt 7 on the main template 1.

[0025] 3): Rotate the locking bolt 7 to tighten it through the threaded hole 9 and secure it to the locking plate 6, completing the installation. Positioning, alignment, and fixing can be completed by a single person, without the need for multiple people to assist in lifting.

[0026] In summary, the pre-drilled hole template for building construction is installed by first inserting the connecting rod 2 into the main template 1 through the connecting hole 8, so that the assembly ring 3 fits against the main template 1; then, the pre-drilled hole template body 5 is slid in through the positioning hole 10, aligned with the positioning pin 4, so that the sealing gasket 12 is embedded in the sealing groove 11, at which point the locking plate 6 is aligned with the locking bolt 7 on the main template 1; finally, the locking bolt 7 is rotated to tighten and fix it to the locking plate 6 through the threaded hole 9, completing the installation. A single person can complete the positioning, alignment, and fixing operations without the need for multiple people to assist in lifting. The engagement of the positioning pin 4 and the positioning hole 10 enables rapid positioning of the pre-reserved hole template body 5, avoiding repeated alignment adjustments. The connection between the locking bolt 7 and the threaded hole 9 simplifies the fixing process and reduces installation time, especially in high-altitude or confined spaces, significantly reducing the labor intensity of construction workers and improving construction efficiency. During assembly, the sealing gasket 12 is embedded into the sealing groove 11 along with the installation of the pre-reserved hole template body 5, forming a sealing structure. The welding of the support plate 13 and the locking plate 6 enhances the strength of the locking part. The connecting rod 2 is connected to the main template 1 through the connecting hole 8, and with the support of the assembly ring 3, the overall structure is subjected to uniform stress. The engagement of the sealing gasket 12 and the sealing groove 11 effectively prevents grout leakage during concrete pouring, ensuring the quality of the pre-reserved hole molding. The support plate 13 enhances the load-bearing capacity of the locking plate 6, preventing the locking bolt 7 from deforming due to excessive force. The synergistic effect of the connecting rod 2 and the assembly ring 3 enhances the connection stability between the pre-reserved hole template body 5 and the main template 1, preventing template displacement during pouring and ensuring accurate pre-reserved hole dimensions.
