Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a high-efficiency concrete pouring formwork for building construction. Background Technology

[0002] Concrete formwork refers to the formwork used to shape freshly poured concrete and the entire structural system supporting the formwork. Formwork can be classified in various ways, including by shape (flat formwork and curved formwork) and by stress conditions (load-bearing and non-load-bearing formwork). Currently, the installation of concrete pouring formwork requires tightening multiple locking bolts, which is a very cumbersome process and affects construction efficiency.

[0003] Based on this, Chinese Patent Publication No. CN214739850U discloses a concrete pouring formwork for construction that is easy to assemble. This patented technology uses a first formwork, a second formwork, and a fixing mechanism: the second formwork engages with slots on the first formwork via inserts on both sides, and the inserts on the connecting plate engage with holes on the inserts. Under the pressure of springs, the inserts are fixed, thus achieving the installation and fixing of the first and second formwork. This design changes the traditional installation method of concrete pouring formwork, facilitates rapid assembly, and improves work efficiency.

[0004] However, as can be seen from the specification and accompanying drawings of the aforementioned patent technology, in specific implementation, the aforementioned patent technology can only produce concrete slabs of fixed size. However, in actual use, it is often necessary to produce concrete slabs of different sizes, such as concrete slabs of different thicknesses. This means that personnel often need to process corresponding casting molds according to the concrete slabs, resulting in excessive costs and hindering the production personnel from quickly casting the concrete slabs. Therefore, the existing concrete casting molds have certain shortcomings in use.

[0005] In conclusion, it is necessary to invent a high-efficiency concrete pouring formwork for building construction projects. Utility Model Content

[0006] Therefore, this utility model provides a high-efficiency concrete pouring template for building construction projects, which solves the problem that personnel often need to process corresponding pouring molds according to the concrete slab, resulting in excessive costs and hindering the rapid pouring of concrete slabs by production personnel.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency concrete pouring formwork for building construction, comprising a first formwork and a second formwork, wherein the second formwork is disposed on both sides of the outer wall of the first formwork, and the first formwork is further provided with an extension component for extending the dimensions;

[0008] The extension component includes an extension mold, which is disposed at both ends of the first template. The upper and lower ends of the outer wall of the first template are respectively provided with splicing blocks and mating holes for connection.

[0009] Preferably, each of the two first templates has a mating strip fixed on the outer wall of one side near the second template, and a splicing slot is provided on both sides of the outer wall of the second template at the position corresponding to the mating strip. The outer wall of the mating strip is slidably inserted into the inner wall of the splicing slot at the corresponding position.

[0010] Preferably, the second template and the mating strip are provided with connecting screw holes at corresponding positions on the top of their outer walls, and the inner walls of the connecting screw holes are threaded with locking bolts to fix the second template and the mating strip.

[0011] Preferably, the sidewalls of the first template and the extension mold connection end are both fixed with curved splicing sliders for connection, and the side ends of the first template and the extension mold are both provided with curved grooves at positions corresponding to the curved splicing sliders, and the outer wall of the curved splicing slider is slidably connected to the inner wall of the curved groove.

[0012] Preferably, the splicing blocks are all fixed to the bottom of the outer wall of the upper first template, and the docking holes are all opened at the top of the outer wall of the first template. The upper and lower first templates are spliced ​​together by the splicing blocks and the docking holes.

[0013] Preferably, each of the two outer wall sides of the first template is fixed with a connecting clamping pin, and the multiple clamping pins are evenly arranged in a strip array. The outer wall of each clamping pin is fitted with an upper fixing collar and a lower fixing collar for connection.

[0014] Preferably, the bottom of the outer wall of the upper fixing collar is fixed with a sleeve by a short rod, the bottom of the outer wall of the sleeve is rotatably connected with an adjusting nut, and the bottom of the inner wall of the sleeve is fitted with a threaded rod for connection.

[0015] Preferably, the outer wall of each threaded rod is threadedly connected to the inner wall of the corresponding adjusting nut, and the bottom end of the outer wall of each threaded rod is fixed to the bottom end of the outer wall of the lower fixing collar by a short rod.

[0016] The beneficial effects of this utility model are:

[0017] In this invention, the extension mold allows for the extension of the length of the first and second templates when needed. The splicing blocks and mating holes allow for the vertical splicing of the two first and second templates when needed. The two first templates are then spliced ​​and fixed by the cooperation of the sleeve and threaded rod, thereby increasing the height of the mold. This allows personnel to adjust the casting mold according to their needs, making it easier to adjust the template and cast the concrete slab. Attached Figure Description

Detailed Implementation

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] See attached document Figures 1-4This utility model provides a high-efficiency concrete pouring formwork for building construction, including a first formwork 100 and a second formwork 200. The second formwork 200 is disposed on both sides of the outer wall of the first formwork 100. The first formwork 100 and the second formwork 200 can cooperate to form a square frame, thereby facilitating the pouring of concrete into concrete slabs. Each of the two first formworks 100 has a butt joint strip 210 fixed to its outer wall on the side closest to the second formwork 200. Each side of the outer wall of the second formwork 200 has a splicing slot at a position corresponding to the butt joint strip 210. The outer wall of the butt joint strip 210 slides into the inner wall of the corresponding splicing slot. The mating insert 210 and splicing slot can be used to install the second template 200 on both sides of the outer wall of the first template 100. The top of the outer wall of the second template 200 and the mating insert 210 are respectively provided with connecting screw holes. The inner wall of the connecting screw hole is threaded with a locking bolt 220 to fix the second template 200 and the mating insert 210. The locking bolt 220 can be inserted into the connecting screw hole of the second template 200 and the mating insert 210 to fix the mating insert 210 and the splicing slot. In this way, the first template 100 and the second template 200 can be spliced ​​and fixed so that they can be assembled into a complete template shape.

[0025] The first template 100 is also provided with an extension component for extending its dimensions. The extension component includes an extension mold 110, which is located at both ends of the first template 100. The extension mold 110 can extend the length of the first template 100 according to the needs of the operator. The first template 100 can be configured as a two-section structure, and when needed, the first template 100 can be separated, and the extension mold 110 can be removed and installed between the first templates 100 to extend its length. The second template 200 can also be configured as a two-section structure as needed, and its length can be adjusted according to requirements. The upper and lower ends of the outer wall of the first template 100 are respectively provided with connecting parts. The splicing insert 130 and the mating hole are fixed to the side walls of the connecting ends of the first template 100 and the extension mold 110. Curved splicing sliders 120 are fixed to the side ends of both the first template 100 and the extension mold 110 at positions corresponding to the curved splicing sliders 120. The outer wall of the curved splicing slider 120 is slidably connected to the inner wall of the curved groove. The curved splicing slider 120 and the curved groove are designed to connect the first template 100 and the extension mold 110 together. A certain amount of damping can be provided between the curved splicing slider 120 and the curved groove to prevent separation of the first template 100 and the extension mold 110. The splicing inserts 130 are all fixed to the bottom of the outer wall of the upper first template 100, and the mating holes are all formed at... At the top of the outer wall of the first template 100, the upper and lower first templates 100 are spliced ​​together by splicing blocks 130 and mating holes. The splicing blocks 130 and mating holes are designed to fix the opposite sides of the outer wall of the upper and lower first templates 100 with connecting clamping pins 140. Multiple clamping pins 140 are evenly arranged in a strip array. The clamping pins 140 are used to fix the two first templates 100 when personnel are splicing them together. The outer wall of each clamping pin 140 is fitted with an upper fixing collar 150 and a lower fixing collar 190 for connection. The bottom of the outer wall of the upper fixing collar 150 is fixed with a sleeve 160 by a short rod. The bottom of the outer wall of each sleeve 160 is rotatably connected with an adjusting nut 17. 0. Each sleeve 160 has a threaded rod 180 fitted onto its inner bottom wall for connection. The outer wall of each threaded rod 180 is threadedly connected to the inner wall of the corresponding adjusting nut 170. The bottom end of the outer wall of each threaded rod 180 is fixed to the bottom end of the outer wall of the lower fixing ring 190 via a short rod. Specifically, the operator can fit the outer wall of the upper fixing ring 150 onto the upper clamping pin 140 and the lower fixing ring 190 onto the clamping pin 140 on the bottom first template 100. Then, the operator can use a wrench to clamp and rotate the adjusting nut 170, causing the adjusting nut 170 to retract into the sleeve 160 by driving the threaded rod 180. This reduces the distance between the upper fixing ring 150 and the lower fixing ring 190.This allows the two first templates 100 to be fixed. The threaded rod 180, sleeve 160, and lower fixing collar 190 can be made of metal, and a certain amount of high damping needs to be provided between the adjusting nut 170 and the bottom of the outer wall of the sleeve 160 to ensure the stability of the device structure.

[0026] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above instructions, and then determine the size of the template according to the required size of the concrete slab. When needed, personnel can separate the two sections of the first template 100 and connect the two sections of the first template 100 with the extension mold 110. The first template 100 and the extension mold 110 can be spliced ​​together by the curved splicing slider 120 and the curved slide groove, so that the first template 100 reaches the required size and shape. Then, personnel can take out the second template 200 and align the splicing slot opened on the side of the second template 200 with the connecting strip 210. Then, the second template 200 and the connecting strip 210 are fixed by the locking bolt 220. In this way, personnel can first spray the release agent on the inner walls of the first template 100 and the second template 200, and then pour the required concrete slab through the first template 100 and the second template 200.

[0027] When the thickness of the concrete slab needs to be increased, the corresponding second-layer first template 100, extension template 110, and second template 200 can be taken out and assembled into a frame. They can then be connected through splicing blocks 130 and mating holes. Then, the sleeve 160 is taken out, and the upper fixing collar 150 and lower fixing collar 190 are respectively fastened to the outer walls of the upper and lower clamping pins 140. The operator can then use a wrench to clamp and rotate the adjusting nut 170, so that the adjusting nut 170 can retract into the sleeve 160 by driving the threaded rod 180. This reduces the distance between the upper fixing collar 150 and the lower fixing collar 190, thereby fixing the two first templates 100. The operator can then continue to pour concrete slabs through the assembled mold plate.

[0028] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
