Description

Technical Field

[0001] This utility model relates to the field of concrete pouring construction technology, and in particular to a pouring template for concrete sewage tank construction. Background Technology

[0002] A concrete sewage tank is a sewage treatment facility made of concrete, primarily used for collecting and treating sewage. It is widely used in industrial parks, urban sewage treatment plants, and rural sewage treatment stations. During construction, concrete sewage tanks typically employ a casting formwork system for concrete pouring. The casting formwork consists of inner and outer formwork, with concrete poured between them. After the concrete hardens, the sewage tank structure is formed.

[0003] However, existing formwork casting methods have some problems during construction. Specifically, there is a lack of effective limiting and fixing measures between the inner and outer formwork. During concrete pouring, the high pressure of the concrete on the formwork can easily cause displacement of either the inner or outer formwork, leading to wall deformation and affecting construction quality. Therefore, existing formwork casting technology needs further improvement to enhance construction stability and quality. Utility Model Content

[0004] The purpose of this utility model is to provide a casting template for the construction of concrete sewage tanks, so as to solve the problems mentioned above.

[0005] The technical solution adopted by this utility model is: a pouring formwork for concrete sewage tank construction, which includes an inner formwork, an outer formwork, a triangular reinforcing frame and a portal-shaped reinforcing frame. The inner formwork and the outer formwork are both annular. The outer formwork is located outside the inner formwork. The triangular reinforcing frame is located at the bottom of the two separated sides to reinforce the bottom of the pouring formwork. The portal-shaped reinforcing frame is erected at the top of the inner formwork and the outer formwork to reinforce the top of the pouring formwork.

[0006] Furthermore, the triangular reinforcement frame includes a first right-angled frame, a second right-angled frame, and a diagonal frame connected in sequence. The first right-angled frame is provided with a first connecting bolt for connecting the inner template or the outer template, and the second right-angled frame is provided with a foundation anchor on the side opposite to the first right-angled frame.

[0007] Furthermore, the foundation anchor includes a protective frame, a first pressure rod, a first pressure plate, and an anchor rod. The bottom end of the protective frame is fixedly connected to the second right-angle frame, and the top end is provided with a first screw hole that is threadedly connected to the first pressure rod. The first pressure plate is slidably disposed inside the protective frame, and the top and bottom sides are respectively connected to the first pressure rod and the anchor rod. The bottom end of the anchor rod penetrates through the second right-angle frame.

[0008] Furthermore, the protective frame is provided with a first guide rod, the first pressure plate is sleeved on the first guide rod, and the bottom end of the first pressure rod is rotatably connected to the first pressure plate.

[0009] Furthermore, the portal frame includes a first connecting plate, a cross-connecting plate, and a second connecting plate connected in sequence. The cross-connecting plate is provided with a second connecting bolt for connecting the inner template or the outer template. The first connecting plate and the second connecting plate are respectively provided with adjustable fasteners, and the two sets of adjustable fasteners are respectively connected to the disjoint surfaces of the inner template and the outer template.

[0010] Furthermore, the adjustable fastener includes a second pressure rod, a second pressure plate, and a limiting block. The second pressure plate is located inside the portal frame, with the second pressure rod and the limiting block connected to its two sides respectively. The first end of the second pressure rod is rotatably connected to the second pressure plate, and the other end is threadedly connected to the first connecting plate or the second connecting plate. The inner template and the outer template are provided with slots that are adapted to the limiting block.

[0011] Furthermore, a second guide rod is provided on the portal frame, one end of which is fixedly connected to the second pressure plate, and the other end slides through the first connecting plate or the second connecting plate; an anti-detachment limiting block is provided on the end of the second guide rod away from the second pressure plate.

[0012] Furthermore, the inner template and the outer template are formed by connecting single templates and limiting strips. Connecting grooves are respectively formed on the connecting sides of adjacent single templates. The opening width of the side end of the connecting groove is smaller than the internal width. The two ends of the limiting strip are inserted into different connecting grooves from the top.

[0013] Furthermore, the top of the limiting insert is provided with a lifting handle.

[0014] The beneficial effects of this utility model are as follows: by setting up triangular and portal-shaped reinforcing frames to reinforce the inner and outer formwork, displacement of the formwork during pouring is effectively prevented, thus improving construction quality. Simultaneously, the inner and outer formwork are connected by individual formwork units and limiting strips, facilitating assembly and disassembly and improving construction efficiency.

[0029] The technical solutions of the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] 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.

[0031] Reference Appendix Figure 1-5 This embodiment provides a casting formwork for the construction of a concrete sewage tank, comprising an inner formwork 1, an outer formwork 2, a triangular reinforcing frame 3, and a portal-shaped reinforcing frame 4. Both the inner formwork 1 and the outer formwork 2 are annular, with the outer formwork 2 positioned outside the inner formwork 1. The triangular reinforcing frame 3 is positioned at the bottom of the outer formwork 2 and the inner formwork 1 on opposite sides, used to reinforce the bottom of the casting formwork; the portal-shaped reinforcing frame 4 is erected at the top of the inner formwork 1 and the outer formwork 2, used to reinforce the top of the casting formwork.

[0032] The area between the inner wall of the outer formwork 2 and the outer wall of the inner formwork 1 serves as the space for pouring the concrete sidewall of the sewage tank. The portal frame 4 and the triangular frame 3 reinforce the top and bottom ends of the pouring formwork, respectively. During the concrete pouring process, they provide limiting compression for the outer formwork 2 and the inner formwork 1, preventing the concrete from expanding and causing the outer formwork 2 or the inner formwork 1 to shift. This can effectively improve the stability and quality of the construction.

[0033] Reference Appendix Figure 3 The triangular reinforcement frame 3 includes a first right-angled frame 31, a second right-angled frame 32, and a beveled frame 33 connected in sequence. The first right-angled frame 31 is provided with a first connecting bolt 7 for connecting the inner template 1 or the outer template 2. Correspondingly, the surfaces of the inner template 1 and the outer template 2 that are separated from each other should be provided with mounting holes for installing the first connecting bolt 7. A foundation anchor 5 is provided on the side of the second right-angled frame 32 opposite to the first right-angled frame 31. The foundation anchor 5 is used to anchor the triangular reinforcement frame 3 to the foundation, ensuring that the second right-angled frame 32 is stably placed on the foundation plane. The triangular stable support structure formed by the first right-angled frame 31 connecting the inner template 1 or the outer template 2, and the two connected by the beveled frame 33, provides good support and restraint to the bottom ends of the inner template 1 and the outer template 2.

[0034] The foundation anchor 5 includes a protective frame 51, a first pressure rod 52, a first pressure plate 53, and an anchor rod 54. The bottom end of the protective frame 51 is fixedly connected to a second right-angle frame 32, and the top end has a first screw hole for threaded connection with the first pressure rod 52. The first pressure plate 53 is slidably disposed inside the protective frame 51, with the first pressure rod 52 and the anchor rod 54 connected to its top and bottom sides respectively. The bottom end of the anchor rod 54 penetrates through the second right-angle frame 32. The first pressure rod 52 is installed in the first screw hole. Rotating the first pressure rod 52 changes the length of the first pressure rod 52 extending into the protective frame 51, thereby changing the height of the first pressure plate 53 and the anchor rod 54, enabling the foundation anchor 5 to be installed or removed from the foundation.

[0035] To improve the ease of installation or disassembly, in this embodiment, external threads are only formed on the side of the first pressure rod 52 near the bottom end, and the bottom end of the first pressure rod 52 is rotatably connected to the first pressure plate 53. When the first pressure rod 52 is at the height of the threaded connection with the first screw hole, the anchor rod 54 is completely located inside the protective frame 51. The anchor rod 54 can be slowly lowered by slowly rotating the first pressure rod 52 to align with its through hole on the second right-angle frame 32. After that, the threaded part of the first pressure rod 52 disengages from the first screw hole, and at this time the anchor rod 54 has also penetrated the second right-angle frame 32. The anchor rod 54 can then be quickly pressed down by hammering the top of the first pressure rod 52. The above process achieves accurate positioning and rapid anchoring of the anchor rod 54.

[0036] Of course, a first guide rod 55 can also be constructed in the protective frame 51. Both the first guide rod 55 and the first pressure rod 52 are vertically constructed. The first pressure plate 53 is sleeved on the first guide rod 55. Since the bottom end of the first pressure rod 52 is rotatably connected to the first pressure plate 53, even if multiple first guide rods 55 are constructed in the protective frame 51, it will not affect the action of pressing down the first pressure plate 53 by rotating the first pressure rod 52. However, the first guide rod 55 can improve the accuracy and stability of the sliding direction of the first pressure plate 53. Therefore, workers can speed up the rotation speed of the first pressure rod 52 during operation to improve efficiency without losing accuracy.

[0037] Reference Appendix Figure 4 The portal frame 4 includes a first connecting plate 41, a bridging plate 42, and a second connecting plate 43 connected in sequence. The bridging plate 42 is provided with a second connecting bolt 8 for connecting the inner formwork 1 or the outer formwork 2. Correspondingly, the top surfaces of the inner formwork 1 and the outer formwork 2 should each have mounting holes for installing the second connecting bolt 8. The first connecting plate 41 and the second connecting plate 43 are respectively provided with adjustable fasteners 6, and the two sets of adjustable fasteners 6 connect the separating surfaces of the inner formwork 1 and the outer formwork 2. The bridging plate 42 in the portal frame can fix the top surfaces of the inner formwork 1 and the outer formwork 2, and can to some extent prevent the top surfaces of the inner formwork 1 and the outer formwork 2 from separating due to concrete pressure. However, its stabilizing effect is relatively small. Therefore, it is necessary to use the first connecting plate 41, the second connecting plate 43, and the adjustable fasteners 6 to press against the separating surfaces of the inner formwork 1 and the outer formwork 2 to further improve the stabilizing effect.

[0038] Since the thickness of the sewage tank sidewall may vary in different construction processes, and in order for the portal frame 4 to be erected on the inner template 1 and outer template 2, the distance between the facing surfaces of the first connecting plate 41 and the second connecting plate 43 must be greater than or equal to the distance between the separating surfaces of the inner template 1 and the outer template 2. However, when the two distances are equal, the friction between the portal frame 4 and the inner template 1 and the outer template 2 is large, which makes installation inconvenient. Therefore, it is preferable that the distance between the facing surfaces of the first connecting plate 41 and the second connecting plate 43 is greater than the distance between the separating surfaces of the inner template 1 and the outer template 2. However, at this time, it is impossible to guarantee the clamping and reinforcement effect of the portal frame on the separating surfaces of the inner template 1 and the outer template 2. Therefore, the aforementioned adjustable fastener 6 is introduced. The adjustable fastener 6 can fill the gap between the portal frame 4 and the inner template 1 and the outer template 2, providing a stronger clamping effect on the inner template 1 and the outer template 2.

[0039] The adjustable fastener 6 includes a second pressure rod 61, a second pressure plate 62, and a limiting block 63. The second pressure plate 62 is located inside the portal frame 4, with the second pressure rod 61 and the limiting block 63 connected to its two sides respectively. One end of the second pressure rod 61 is rotatably connected to the second pressure plate 62, and the other end is threadedly connected to the first connecting plate 41 or the second connecting plate 43. The inner template 1 and the outer template 2 are provided with slots 111 that are adapted to the limiting block 63. Similar to the installation and removal method of the foundation anchor 5, in the adjustable fastener 6, by rotating the second pressure rod 61, the second pressure plate 62 and the limiting block 63 can be moved closer to the inner template 1 or the outer template 2, thereby causing the limiting block 63 to be inserted into the slot 111, and the second pressure plate 62 to press against the inner template 1 or the outer template 2, ensuring the stability of the distance between the inner template 1 and the outer template 2, and preventing the concrete from expanding and causing it to shift or tilt.

[0040] In addition, a second guide rod 64 can be constructed on the portal frame 4. Both the second guide rod 64 and the second pressure rod 61 are constructed laterally. One end of the second guide rod 64 is fixedly connected to the second pressure plate 62, and the other end slides through the first connecting plate 41 or the second connecting plate 43. An anti-disengagement limiting block is constructed on the end of the second guide rod 64 away from the second pressure plate 62. The second guide rod can provide stable guidance for the second pressure plate 62, so that the second pressure plate 62 can ensure the positional accuracy of the limiting block 63 and the slot 111 during rapid movement, thereby improving construction efficiency.

[0041] Reference Appendix Figure 5To facilitate the manufacturing, transportation, and installation of the casting formwork, the inner formwork 1 and the outer formwork 2 are connected by individual formwork 11 and limiting strips 12. Connecting grooves 112 are respectively formed on the connecting sides of adjacent individual formwork 11. The width of the side opening of the connecting groove 112 is smaller than its internal width. The two ends of the limiting strip 12 are inserted into different connecting grooves 112 from the top. A lifting handle 13 is formed at the top of the limiting strip 12. Because the width of the side opening of the connecting groove 112 is smaller than its internal width, the limiting strip 12 cannot be detached from the side opening of the connecting groove 112, but can only be installed and removed by sliding vertically. However, once installed, workers will not arbitrarily operate the lifting handle 13, effectively ensuring the connection stability of adjacent individual formwork 11.

[0042] Taking a square concrete sewage tank as an example, the corners of its side walls are joined together by two individual formwork panels 11. The connecting grooves 112 on these two individual formwork panels 11 are located on the narrow side of the individual formwork panel 11 and on the large surface of the individual formwork panel 11 (see attached). Figure 2 This facilitates the installation of templates at the corners; while the connecting grooves 112 on the remaining individual templates 11 are all located on the narrow side of the individual templates 11.

[0043] Reference Appendix Figure 5 The connecting groove 112 on the inner template 1 and the outer template 2 can be configured with a cross-shaped or T-shaped cross section (T-shaped not shown) to meet the requirement that "the width of the side opening of the connecting groove 112 is less than the internal width". Of course, those skilled in the art can also make adaptive changes based on the cross-sectional shape provided above, as long as the requirement that "the width of the side opening of the connecting groove 112 is less than the internal width" is met.

[0044] During construction, the individual formwork 11 is first connected to form the inner formwork 1 and the outer formwork 2 using limiting inserts 12. Then, triangular reinforcing frames 3 are installed at the bottom of the inner formwork 1 and the outer formwork 2, and the bottom of the formwork is fixed to the foundation using foundation anchors 5. Next, portal-shaped reinforcing frames 4 are installed at the top of the inner formwork 1 and the outer formwork 2, and the inner formwork 1 and the outer formwork 2 are tightly connected using adjustable fasteners 6. Finally, concrete pouring is carried out.

[0045] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up the triangular reinforcing frame 3 and the portal-shaped reinforcing frame 4, the inner formwork 1 and the outer formwork 2 are reinforced, effectively preventing the formwork from shifting during the pouring process and improving the construction quality. At the same time, the inner formwork 1 and the outer formwork 2 are connected by single formwork 11 and limiting strips 12, which facilitates assembly and disassembly and improves construction efficiency.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.

[0047] 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.
