Description

Technical Field

[0001] This utility model relates to the field of reverse retaining wall construction technology, and in particular to a reverse retaining wall casting template. Background Technology

[0002] A retaining wall is an important structural feature in building construction. It is generally made of cast concrete, placed on the floor and protruding from the base plate, and is used to prevent outdoor water from flowing into the room or to prevent water from seeping between different rooms (e.g., water from the bathroom seeping into other rooms).

[0003] The retaining wall is part of the building structure; therefore, according to traditional construction procedures, its construction precedes the underfloor heating installation. This not only helps ensure the integrity and stability of the main structure but also facilitates the construction of the waterproofing layer. However, since the retaining wall protrudes from the base slab, its initial construction will affect the laying of the underfloor heating pipes at the doorway. This necessitates cutting grooves in the retaining wall when laying the pipes, increasing construction difficulty, reducing efficiency, and causing variations in groove quality due to differences in construction experience, ultimately impacting the final construction results of both the retaining wall and the underfloor heating system. Utility Model Content

[0004] The purpose of this utility model is to provide a reverse retaining wall casting template to overcome the shortcomings in the above-mentioned background technology.

[0005] The technical solution of this utility model is: a reverse-slope casting template, which includes a first side mold, a second side mold and an adjustable distance fixing device. The first side mold and the second side mold are parallel and spaced apart to form a casting area. The two are connected by the adjustable distance fixing device, which can adjust the width dimension of the casting area. At least two sets of third side molds are provided in the casting area. The third side molds extend along the width of the casting area and can divide the casting area into at least a first partition, a second partition and a third partition that are independent of each other. The first partition, the second partition and the third partition are dispersed along the length of the casting area.

[0006] Furthermore, the two ends of the third side mold are movably connected to the first side mold and the second side mold, respectively, and can move along the length of the casting area to change the size of the first partition, the second partition and / or the third partition.

[0007] Furthermore, the first side mold and the second side mold are respectively provided with a first straight through groove corresponding to the position, and the first straight through groove extends along the length of the casting area; the third side mold includes a first connecting rod slidably disposed in the first straight through groove, the outer wall of the first connecting rod is provided with threads, and the two ends are respectively connected to a first locking nut located outside the casting area.

[0023] The technical solutions of the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] In the description of the embodiments of this utility model, it should be understood that the terms "top," "bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be noted that unless otherwise expressly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model through specific circumstances.

[0025] Reference Appendix Figure 1-4 This utility model provides a reverse-slope casting template, which specifically includes: a first side mold 1, a second side mold 2, a distance adjusting device 4, and at least two sets of third side molds 3. The first side mold 1 and the second side mold 2 are arranged parallel and spaced apart to form a casting area 5. The two are connected by the distance adjusting device 4. The distance adjusting device 4 can adjust the width dimension of the casting area 5 by adjusting the distance between the first side mold 1 and the second side mold 2. The third side mold 3 is located in the casting area 5 and extends along the width of the casting area 5. At least two sets of third side molds 3 can divide the casting area 5 into at least three independent sections: a first section 51, a second section 52, and a third section 53. The first section 51, the second section 52, and the third section 53 are dispersed along the length of the casting area 5.

[0026] During construction, the first side mold 1 and the second side mold 2 are placed on both sides of the wall, covering the lower end of the door opening. The first side mold 1, the second side mold 2, and the two side walls of the door opening form the pouring area 5. The distance between the first side mold 1 and the second side mold 2 is adjusted by the adjusting fixture 4, which can press the first side mold 1 and the second side mold 2 against both sides of the wall to prevent them from loosening during pouring. Due to the setting of the adjusting fixture 4, this anti-sill pouring template can be used for walls of different thicknesses. The first section 51 and the third section 53, which are separated by the third side mold 3, can be used as the actual pouring area 5 of the anti-sill, while the second section 52 is not poured with mortar to provide installation space for the underfloor heating pipes. This avoids the need to perform grooving work after the anti-sill is poured, avoids damage to the anti-sill structure, saves working time, and comprehensively improves construction quality and efficiency.

[0027] In the above construction plan, compared with the size of the door opening, the size of the second section 52 reserved for the installation of underfloor heating pipes is relatively small. After the first section 51 and the third section 53 are poured, waterproofing construction can be carried out. After the underfloor heating pipes are installed, the second section 52 is sealed and waterproofed, which will not affect the overall waterproof and seepage prevention effect of the inverted wall.

[0028] In this embodiment, the two ends of the third side mold 3 are movably connected to the first side mold 1 and the second side mold 2, respectively, and can move along the length of the casting area 5 to change the size of the first partition 51, the second partition 52 and the third partition 53.

[0029] Specifically, the first side mold 1 and the second side mold 2 are respectively provided with a first through groove 11 corresponding to the position, and the first through groove 11 extends along the length of the casting area 5; the third side mold 3 includes a first connecting rod 31 slidably disposed in the first through groove 11, the outer wall of the first connecting rod 31 is provided with threads, and the two ends are respectively connected to a first locking nut 32 located outside the casting area 5.

[0030] By loosening the first locking nut 32 and sliding the first connecting rod 31 along the first through groove 11, the position of the third side mold 3 in the pouring area 5 can be changed, thereby changing the size of the first partition 51, the second partition 52 and the third partition 53, and adjusting the position and size of the second partition 52 to adapt to different construction needs.

[0031] In this embodiment, the first side mold 1 is a longitudinally arranged flat plate structure, and the second side mold 2 includes a vertical wall 21 and a slope wall 22. The vertical wall 21 is parallel to the first side mold 1 and is located at the top of the slope wall 22. The bottom end of the slope wall 22 is inclined away from the first side mold 1, so that the actual cast-in-place curb has a slope surface, so as to better prevent water seepage and overflow.

[0032] In order to strictly separate the first partition 51, the second partition 52 and the third partition 53, the third side mold 3 in this embodiment has a surface that tightly abuts against the first side mold 1 and a surface that tightly abuts against the second side mold 2. In order to tightly abut against the second side mold 2, the surface of the third side mold 3 that abuts against the second side mold 2 should have at least a vertical part 33 and a slope part 34. The vertical part 33 is located at the top of the slope part 34, and the slope part 34 has the same inclination angle and height as the slope wall 22.

[0033] Since the distance between the first side mold 1 and the second side mold 2 is adjustable, a third side mold 3 of various sizes can be prefabricated according to the above-mentioned shape characteristics, so as to facilitate quick selection during construction.

[0034] Reference Appendix Figure 2 The first side mold 1 and the second side mold 2 are respectively provided with corresponding second straight grooves 12, which extend along the length of the casting area 5; the adjusting fixture 4 includes a second connecting rod 41 that is slidably disposed in the second straight groove 12, the outer wall of the second connecting rod 41 is provided with threads, and at least one end is connected to a second locking nut 43 located outside the casting area 5.

[0035] More specifically, the second connecting rod 41 can have different second locking nuts 43 connected to its two ends, or it can have a limiting part 42 at one end and a second locking nut 43 connected to the other end, wherein the radial dimension of the limiting part 42 is larger than the width of the second through groove 12. In the latter case, a long bolt can be used instead of the second connecting rod 41. Due to the presence of the limiting part 42, the number of second locking nuts 43 installed can be reduced, simplifying the construction operation and improving construction efficiency.

[0036] During construction, the number of adjustable fixing devices 4 and the position of sliding adjustable fixing devices 4 can be increased or decreased according to the position of the third side formwork 3 and the formwork fastening requirements.

[0037] It is worth noting that both the first straight groove 11 and the second straight groove 12 should be higher than the top surface elevation of the curb to avoid grout leakage. In addition, since the first straight groove 11 and the second straight groove 12 are distributed in the vertical direction, after the first locking nut 32 and the second locking nut 43 are locked respectively, the first side mold 1 (or the second side mold 2) has two sets of fastening points in the vertical direction. And since the height of the curb is generally low, the height of the first side mold 1 (or the second side mold 2) is also correspondingly low. With the coordinated limiting of the first connecting rod 31, the second connecting rod 41, the first locking nut 32 and the second locking nut 43, the tightness between the first side mold 1 (or the second side mold 2) and the wall can be guaranteed. In actual construction, it has been verified that with this technical solution, the bottom of the first side mold 1 and the second side mold 2 will not tilt or overflow even without other fastening measures.

[0038] When constructing the inverted curb using the above-mentioned casting template, firstly, place the first side mold 1 and the second side mold 2 on both sides of the wall, with the second side mold 2 located on the water-facing side of the inverted curb (e.g., the inside of the bathroom); then, install the third side mold 3 between the first side mold 1 and the second side mold 2, and pre-connect the first locking nut 32 and the second locking nut 43 to the first connecting rod 31 and the second connecting rod 41, respectively, so that the first connecting rod 31 and the second connecting rod 41 can slide but cannot detach from the first side mold 1 and the second side mold 2; then, precisely adjust the position of the third side mold 3 and the adjusting fixing device 4 according to the construction plan, and lock the first locking nut 32 and the second locking nut 43, so that the facing surfaces of the first side mold 1 and the second side mold 2 are pressed against the wall and the third side plate; pour mortar in the first section 51 and the third section 53 to construct the inverted curb, and after solidification, remove the formwork and construct the waterproof layer; after installing the underfloor heating pipes in the second section 52, seal and refine the waterproof layer.

[0039] Compared with the prior art, the beneficial effects of this utility model include at least the following: by setting the third side mold 3, the pouring area 5 is divided into the first section 51 and the third section 53 as the actual pouring area 5 of the reverse curb, while the second section 52 is not poured with mortar, providing installation space for the underfloor heating pipes. This avoids the need for grooving after the reverse curb is poured, thus avoiding damage to the reverse curb structure and saving working time, thereby comprehensively improving construction quality and efficiency. In addition, through the design of the adjustable fixing device 4 and the third side mold 3, this reverse curb pouring template can be applied to different wall thicknesses and different requirements for reserved construction areas for underfloor heating pipes, thereby improving the practicality of this template.

[0040] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
