Abstract
Description
Technical Field
[0001] This utility model relates to the field of molding technology, specifically to a molding mold for external wall pipe laying. Background Technology
[0002] In municipal infrastructure construction and building exterior wall engineering, the exterior wall duct system serves as a laying channel for cables (including power cables, communication cables, etc.). The installation accuracy directly determines the smoothness of subsequent cable laying, the safety of cable operation, and the overall functionality of the project. Currently, exterior wall cable duct construction typically requires simultaneous duct positioning during concrete pouring. This involves placing prefabricated duct components within the pouring formwork according to the designed spacing, direction, and elevation. Concrete pouring then integrates the duct with the exterior wall structure, ultimately forming a closed channel for cable installation.
[0003] However, existing construction methods generally suffer from poor positioning reliability, specifically manifested in the following ways: During the concrete pouring stage, due to the lateral impact force and flow pressure generated by concrete vibration, as well as accidental contact by construction personnel, pipes without effective fixing measures are prone to displacement, offset, or spacing deviation, resulting in "misalignment" problems. For pipes that require internal cable installation, the hazards of such misalignment are even more pronounced: On the one hand, pipe axis misalignment or interface misalignment can lead to poor connection between adjacent pipes, making cable installation prone to obstruction, increasing construction difficulty, and potentially scratching the cable sheath, causing safety hazards such as leakage and signal interruption; on the other hand, pipe spacing deviations may exceed the design specifications for cable laying, leading to poor cable heat dissipation, accelerated insulation aging, shortened cable lifespan, and significant inconvenience for subsequent cable maintenance and replacement. Utility Model Content
[0004] To overcome the above-mentioned defects, the present invention provides an external wall pipe shaping mold, which solves the technical problem that municipal pipes are prone to misalignment when pouring concrete in the prior art.
[0005] According to one aspect, at least one embodiment of the present invention provides an external wall pipe-setting mold for positioning pipes during external wall pouring, comprising: A shaping template is provided, which has several through holes, each corresponding to a pipe. The shaping template is used to position and install the pipe through the through holes. A plurality of connecting rods are provided, with at least one connecting rod provided between two adjacent pipes, and the connecting rods are used to limit the movement of the pipes; Fasteners are detachably mounted on the shaping template, and the fasteners fix the connecting rods on the shaping template.
[0006] Optionally, the shaping template is further provided with a number of reinforcing strips, and a reinforcing strip is provided between two adjacent pipes. The connecting rod overlaps the reinforcing strip and is arranged perpendicular to the reinforcing strip.
[0007] Optionally, the shaped template is connected to the externally installed finished template via the reinforcing strip and the connecting rod.
[0008] Optionally, a self-adhesive waterproof membrane is laid on the surface of the template near the exterior wall.
[0009] Optionally, the thickness of the self-adhesive waterproof membrane is 3mm.
[0010] Optionally, the fastener is a U-shaped fastener.
[0011] Optionally, the inner diameter of the through hole is the same as the outer diameter of the pipe.
[0012] Optionally, the through holes are arranged in a rectangular array, and the shape of the through holes is adapted to the cross-sectional shape of the pipe.
[0013] Optionally, the reinforcing strip is rectangular.
[0014] Optional, also includes: An anchor rod is installed on a steel reinforcement frame inside the outer wall. The end of the anchor rod away from the steel reinforcement frame passes through the fixed template and is detachably connected to the anchor rod.
[0015] The beneficial effects of this utility model are as follows: In this invention, during construction, the pipes are inserted one by one into the through holes of the template to initially position them, ensuring that the pipes are distributed according to the design direction and elevation. Connecting rods are laid between adjacent pipes, with the connecting rods tightly against the outer wall of the pipes to form a lateral limit on the pipes. The two ends of the connecting rods are locked to the template with fasteners to ensure the stability of the connecting rods and prevent lateral displacement of the pipes during subsequent construction. The assembled template and pipes are placed inside the outer wall casting template for concrete pouring. During the pouring process, the template continuously positions the pipes. After the concrete has cured to the design strength, the fasteners are removed, the connecting rods are taken out, and the template is peeled off from the outer wall surface, completing the pipe positioning construction. The longitudinal positioning of the pipes through the through holes and the lateral limiting of the connecting rods form a double fixing structure, effectively resisting the lateral impact force and flow pressure generated by concrete vibration, and avoiding pipe displacement, offset, or spacing deviation. The pipe positioning is precise, the connection between adjacent pipe channels is smooth, there is no jamming when the cable is laid, it prevents scratches on the cable sheath, and reduces safety hazards such as leakage and signal interruption. It reduces rework caused by pipe misalignment, shortens the construction cycle, and meets the requirements of cable laying design specifications, ensures the heat dissipation effect of the cable, extends the service life of the cable, and provides convenience for subsequent maintenance and replacement operations.

[0024] like Figures 1-2As shown, this invention illustrates an external wall pipe shaping mold in one embodiment, used for positioning pipes 2 during the pouring of the external wall 1. The mold includes a shaping template 3 with several through holes 31, each corresponding to a pipe 2. The shaping template 3 uses the through holes 31 to position the pipes 2. Several connecting rods 4 are provided, with at least one connecting rod 4 between two adjacent pipes 2. The connecting rods 4 are used to limit the movement of the pipes 2. Fasteners 5 are detachably mounted on the shaping template 3, fixing the connecting rods 4 to the shaping template 3.
[0025] In the above scheme, the external wall pipe-laying mold consists of three parts: a molding template 3, connecting rods 4, and fasteners 5. The molding template 3 is a rectangular steel plate structure with several through holes 31 evenly distributed on the plate. The number of through holes 31 is exactly the same as the number of pipes 2 to be positioned, and the position of each through hole 31 must be strictly determined according to the spacing, direction, and elevation of the pipes 2 in the engineering design. The connecting rods 4 are steel bars, and their number is configured according to the number of pipes 2. At least one connecting rod 4 is set between every two adjacent pipes 2 to ensure the limiting coverage of the pipes 2. The fasteners 5 are detachable and installed on the surface of the molding template 3 to fix the relative position of the connecting rods 4 and the molding template 3.
[0026] During construction, the pipes 2 are inserted one by one into the through holes 31 of the template 3 to initially position the pipes 2, ensuring that the pipes 2 are distributed according to the design direction and elevation. Connecting rods 4 are laid between adjacent pipes 2, so that the connecting rods 4 are close to the outer wall of the pipes 2, forming a lateral limit for the pipes 2. The two ends of the connecting rods 4 are locked to the template 3 with fasteners 5 to ensure the stability of the connecting rods 4 and prevent the pipes 2 from shifting laterally during subsequent construction. The assembled template and pipes 2 are placed as a whole in the pouring template of the outer wall 1 for concrete pouring. During the pouring process, the template continuously positions the pipes 2. After the concrete has cured to the design strength, the fasteners 5 are removed, the connecting rods 4 are taken out, and the template 3 is peeled off from the surface of the outer wall 1, completing the positioning construction of the pipes 2.
[0027] The longitudinal positioning of the pipe 2 via the through hole 31 and the lateral limiting of the connecting rod 4 form a double fixing structure, effectively resisting the lateral impact force and flow pressure generated by concrete vibration, and preventing displacement, offset or spacing deviation of the pipe 2; the pipe 2 is accurately positioned, the connection between adjacent pipe 2 channels is smooth, there is no jamming when the cable is laid, it prevents scratches on the cable outer sheath, and reduces safety hazards such as leakage and signal interruption; it reduces rework caused by misalignment of the pipe 2, shortens the construction cycle, and meets the requirements of cable laying design specifications, ensures the heat dissipation effect of the cable, extends the service life of the cable, and provides convenience for subsequent maintenance and replacement operations.
[0028] In some examples, the template 3 is also provided with several reinforcing strips 6, and a reinforcing strip 6 is provided between two adjacent pipes 2. The connecting rod 4 overlaps the reinforcing strip 6 and is arranged perpendicular to the reinforcing strip 6.
[0029] In the above scheme, several reinforcing strips 6 are welded to the surface of the template 3. The cross-section of the reinforcing strips 6 is rectangular. The arrangement of the reinforcing strips 6 corresponds to the spacing of the pipes 2. One reinforcing strip 6 is set between every two adjacent pipes 2, and the reinforcing strips 6 extend along the length of the template 3. The connecting rod 4 overlaps the reinforcing strip 6 and is perpendicular to the reinforcing strip 6 to form a "well" shaped limiting structure. The two ends of the connecting rod 4 are fixed to the reinforcing strip 6 by fasteners 5. After machining the through hole 31 in the template 3, weld the reinforcing strip 6 to the surface of the template 3 according to the design spacing, ensuring that the center line of the reinforcing strip 6 coincides with the center line of the gap between the adjacent pipes 2; Install the pipes 2 and the connecting rod 4: After inserting the pipes 2 into the through hole 31, place the connecting rod 4 horizontally on the adjacent reinforcing strip 6, adjust the position of the connecting rod 4 so that the connecting rod 4 is close to the outer wall of the pipes 2; lock the connecting rod 4 and the reinforcing strip 6 with the fastener 5 so that the reinforcing strip 6 and the connecting rod 4 together form a three-dimensional limiting structure for the pipes 2.
[0030] The vertical arrangement of the reinforcing strip 6 and the connecting rod 4 upgrades the single lateral limiting to a three-dimensional support structure, further enhancing the fixing strength of the pipe 2 and enabling it to withstand greater concrete impact. The reinforcing strip 6 enhances the deformation resistance of the formwork 3 itself, preventing the formwork from bending due to stress during construction and ensuring the positioning accuracy of the pipe 2. The reinforcing strip 6 provides a clear lap benchmark for the connecting rod 4, reducing the position adjustment time during the installation of the connecting rod 4 and improving construction efficiency.
[0031] In some examples, the prefabricated template 3 is connected to the externally installed finished template via reinforcing strips 6 and connecting rods 4.
[0032] In the above scheme, the fixed template 3 is connected to the finished template used for the construction of the outer wall 1 through the reinforcing strip 6 and the connecting rod 4. The specific connection structure is as follows: the two ends of the reinforcing strip 6 extend to the edge of the fixed template 3, and the end of the reinforcing strip 6 is provided with a connecting hole; the inner side of the finished template is pre-set with a connector, and the connector matches the connecting hole at the end of the reinforcing strip 6; the two ends of the connecting rod 4 that extend beyond the reinforcing strip 6 are also provided with through holes, which can be locked with the connector of the finished template by bolts, forming a rigid connection between the fixed template 3 and the finished template.
[0033] Move the prefabricated template 3, consisting of assembled pipe 2, reinforcing strip 6, and connecting rod 4, to the construction position of the exterior wall 1, aligning the end of the reinforcing strip 6 of the prefabricated template with the connector of the finished template. Lock the reinforcing strip 6 to the connector of the finished template by passing bolts through the connecting holes at the ends of the reinforcing strip 6, and simultaneously fix the through holes at both ends of the connecting rod 4 to the corresponding connectors of the finished template, ensuring that the prefabricated template 3 and the finished template fit tightly without relative displacement. After the connection is completed, pour concrete for the exterior wall 1. The prefabricated template 3 remains stable under the support of the finished template, continuously positioning the pipe 2. After the concrete has cured to the required standard, first remove the connecting bolts between the connecting rod 4 and the finished template, then remove the connection structure between the reinforcing strip 6 and the finished template, and finally remove the finished template and the prefabricated template 3 in sequence.
[0034] The pre-formed template 3 is rigidly connected to the finished template, so that the positioning of the pipe 2 is synchronized with the positioning of the external wall 1 casting template, avoiding deviation of the pipe 2 due to template misalignment.
[0035] The two are connected to form a unified support system, which reduces the risk of formwork shaking or overturning during construction and ensures the safety of workers; there is no need to set up a separate support structure for the prefabricated formwork 3, and the existing finished formwork can be used to achieve fixation, reducing construction costs and shortening the construction period.
[0036] In some examples, the surface of the template 3 near the exterior wall 1 is covered with a self-adhesive waterproof membrane 7.
[0037] In the above scheme, a layer of self-adhesive waterproof membrane 7 is fully laid on the surface of the template 3 near the exterior wall 1. The waterproof membrane is made of modified bitumen material, which has good adhesion and impermeability. The waterproof membrane is completely adhered to the surface of the template 3, with its edges extending beyond the edge of the template 3, ensuring that there are no gaps between the template 3 and the exterior wall 1. After the template 3 is processed, dust, oil, and other impurities are cleaned from the template surface. Then, the release film of the self-adhesive waterproof membrane 7 is removed, and the membrane is laid flat on the surface of the template 3 near the exterior wall 1. It is then compacted with a roller to ensure that there are no air bubbles or wrinkles between the membrane and the template. The template 3 with the waterproof membrane laid on it is then installed in place as required, so that the waterproof membrane is tightly attached to the pouring surface of the exterior wall 1. During the concrete pouring process, the waterproof membrane can prevent concrete slurry from seeping into the gap between the template 3 and the exterior wall 1. When the template is removed, the waterproof membrane is peeled off along with the template 3, or partially remains on the surface of the exterior wall 1 to form an additional waterproof layer.
[0038] It effectively prevents grout leakage during concrete pouring, avoiding quality problems such as cracks and leaks in the exterior wall 1 and extending the service life of the exterior wall 1; it prevents concrete grout from sticking to the surface of the formwork 3, reducing the amount of formwork cleaning and extending the service life of the formwork; it eliminates the need for separate local waterproofing treatment of the exterior wall 1 after the pipe 2 is positioned, combining the waterproofing process with the pipe 2 positioning process to improve construction efficiency.
[0039] In some examples, the thickness of the self-adhesive waterproofing membrane 7 is 3 mm.
[0040] In the above solution, the thickness of the self-adhesive waterproofing membrane 7 is strictly controlled to 3 mm. The membrane base material is polyester felt, the upper surface is covered with a polyethylene film protective layer, and the lower surface is coated with a self-adhesive adhesive layer. The overall thickness error does not exceed ±0.2 mm, which ensures that the membrane has sufficient puncture resistance and good flexibility.
[0041] In some examples, the fastener 5 is a mountain clamp.
[0042] In the above solution, the fastener 5 adopts a mountain clamp, which is made of cast iron and is generally in a "mountain" shape. A circular through hole is provided in the middle, and the aperture of the through hole matches the diameter of the connecting rod 4. The claws at both ends of the mountain clamp can tightly clamp the edge of the setting formwork 3 or the reinforcing bar 6, and locking is realized through matching bolts and nuts. In some examples, the inner diameter of the through hole 31 is the same as the outer diameter of the pipe row 2.
[0043] In the above solution, the inner diameter of the through hole 31 on the setting formwork 3 is exactly the same as the outer diameter of the pipe row 2. The pipe row 2 is slowly threaded into the through hole 31. Since the inner diameter matches the outer diameter, the pipe row 2 can closely fit the inner wall of the through hole 31, and accurate positioning can be achieved without additional adjustment. During concrete pouring, the tight fit between the through hole 31 and the pipe row 2 can prevent slurry from penetrating into the pipe row 2 and avoid shaking of the pipe row 2 in the hole at the same time.
[0044] In some examples, the through holes 31 are arranged in a rectangular array, and the shape of the through holes 31 matches the cross-sectional shape of the pipe row 2.
[0045] In the above solution, the through holes 31 are arranged in a rectangular array on the setting formwork 3, and the pipe rows 2 are threaded into the corresponding through holes 31 in the order of the rectangular array. Due to the array arrangement and shape adaptation, the pipe rows 2 can be positioned quickly and arranged neatly as a whole. The rectangular array arrangement makes the spacing between the pipe rows 2 uniform and the arrangement neat, which fully meets the design specification requirements for cable laying and ensures the heat dissipation effect of cables. Adjusting the shape of the through hole 31 according to the cross-sectional shape of the pipe row 2 can meet the positioning requirements of pipe rows 2 with different cross-sections such as circular and rectangular, which improves the versatility of the mold.
[0046] In some examples, the reinforcing bar 6 is rectangular.
[0047] It should be noted that the above embodiments are only used to explain the technical solution of the present utility model, and are not intended to limit it. Although the present utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of the present utility model without departing from the spirit and scope of the technical solution of the present utility model, and all such modifications and equivalent substitutions shall be included in the scope of the claims of the present utility model.
