[0034] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0036] Reference Figure 1-5 The present embodiment provides a casting template for concrete sewage pool construction, which includes an inner template 1, an outer template 2, a triangular reinforcement frame 3 and a gate-shaped reinforcement frame 4. The inner template 1 and the outer template 2 are both annular, and the outer template 2 is arranged outside the inner template 1. The triangular reinforcement frame 3 is arranged at the bottom end of the separated side of the outer template 2 and the inner template 1, and is used to reinforce the bottom end of the casting template; the gate-shaped reinforcement frame 4 is arranged at the top end of the inner template 1 and the outer template 2, and is used to reinforce the top end of the casting template.

[0037] The area between the inner wall of the outer formwork 2 and the outer wall of the inner formwork 1 is used as the space for pouring the concrete side wall of the sewage tank, and the gate-shaped reinforcement frame 4 and the triangular reinforcement frame 3 respectively reinforce the top and bottom ends of the pouring formwork. During the process of pouring concrete, the outer formwork 2 and the inner formwork 1 are provided with limited extrusion to prevent the concrete from expanding the formwork and causing the outer formwork 2 or the inner formwork 1 to shift, which can effectively improve the stability and quality of the construction.

[0038] Reference Figure 3 The triangular reinforcement frame 3 includes a first right-angle frame 31, a second right-angle frame 32 and an oblique frame 33 which are connected in sequence. The first right-angle frame 31 is provided with a first connecting bolt 7 for connecting the inner template 1 or the outer template 2. Accordingly, the separated surfaces of the inner template 1 and the outer template 2 should be respectively provided with mounting holes for installing the first connecting bolt 7; the second right-angle frame 32 is provided with a foundation anchor 5 on the side away from the first right-angle frame 31. The foundation anchor 5 is used to anchor the triangular reinforcement frame 3 to the foundation, so that the second right-angle frame 32 is firmly placed on the foundation plane, and the first right-angle frame 31 is connected to the inner template 1 or the outer template 2. The triangular stable support structure formed by the two connected by the oblique frame 33 can provide good support and limiting effect to the bottom ends of the inner template 1 and the outer template 2.

[0039] 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 the second right-angle frame 32, and the top end is provided with a first screw hole threadedly connected to the first pressure rod 52. The first pressure plate 53 is slidably arranged inside the protective frame 51, and the top and bottom sides are respectively connected to the first pressure rod 52 and the anchor rod 54, and the bottom end of the anchor rod 54 passes through the second right-angle frame 32. The first pressure rod 52 is installed in the first screw hole, and the first pressure rod 52 is rotated to change 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, so as to realize the installation or removal of the foundation anchor 5 from the foundation.

[0040] To improve the convenience of installation or disassembly, in this embodiment, only an external thread is constructed on the side surface of the first pressure rod 52 close to the bottom end, and the bottom end of the first pressure rod 52 is rotated to connect to the first pressure plate 53. When the first pressure rod 52 is at a height connected to the first screw hole through a thread, the anchor rod 54 is completely located on the inner side of the protective frame 51. The first pressure rod 52 can be slowly rotated to slowly lower the anchor rod 54 to align with the through hole on the second right-angle frame 32. After that, the threaded portion of the first pressure rod 52 is disengaged from the first screw hole. At this time, the anchor rod 54 has also penetrated the second right-angle frame 32. The anchor rod 54 can 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.

[0041] Of course, a first guide rod 55 can also be constructed in the protective frame 51. The first guide rod 55 and the first pressure rod 52 are both vertically constructed, and 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, the action process of pressing down the first pressure plate 53 by rotating the first pressure rod 52 is not affected. However, the first guide rod 55 can improve the accuracy and stability of the sliding direction of the first pressure plate 53. Therefore, the worker can speed up the rotation speed of the first pressure rod 52 during the operation to improve efficiency without losing accuracy.

[0042] Reference Figure 4The gate-shaped reinforcement frame 4 includes a first connecting plate 41, a jumper plate 42 and a second connecting plate 43 which are connected in sequence. The jumper plate 42 is provided with a second connecting bolt 8 for connecting the inner formwork 1 or the outer formwork 2. Accordingly, the top surfaces of the inner formwork 1 and the outer formwork 2 should be provided with mounting holes for installing the second connecting bolt 8. The first connecting plate 41 and the second connecting plate 43 are provided with adjustable fasteners 6, respectively. The two sets of adjustable fasteners 6 are connected to the separated surfaces of the inner formwork 1 and the outer formwork 2, respectively. The jumper plate 42 in the gate-shaped reinforcement frame can fix the top surfaces of the inner formwork 1 and the outer formwork 2, and can prevent the top surfaces of the inner formwork 1 and the outer formwork 2 from being separated by concrete compression to a certain extent. However, its stabilizing effect is relatively small, so it is also necessary to use the first connecting plate 41, the second connecting plate 43 and the adjustable fasteners 6 to press against the separated surfaces of the inner formwork 1 and the outer formwork 2 to further improve the stabilizing effect.

[0043] Since the thickness of the side wall of the sewage pool may not be the same during different constructions, in order to enable the gate-shaped reinforcement frame 4 to be erected on the inner formwork 1 and the outer formwork 2, the spacing between the facing surfaces of the first connecting plate 41 and the second connecting plate 43 must be greater than or equal to the spacing between the separated surfaces of the inner formwork 1 and the outer formwork 2. However, when the above two spacings are equal, the friction between the gate-shaped reinforcement frame 4 and the inner formwork 1 and the outer formwork 2 is relatively large, which is not convenient for installation. Therefore, it is more preferred that the spacing between the facing surfaces of the first connecting plate 41 and the second connecting plate 43 is greater than the spacing between the separated surfaces of the inner formwork 1 and the outer formwork 2. At this time, the gate-shaped reinforcement frame cannot ensure the tightening and reinforcing effect on the separated surfaces of the inner formwork 1 and the outer formwork 2. Therefore, the above-mentioned adjustable fastener 6 is introduced. The adjustable fastener 6 can fill the gap between the gate-shaped reinforcement frame 4 and the inner formwork 1 and the outer formwork 2, providing a stronger tightening effect on the inner formwork 1 and the outer formwork 2.

[0044] Among them, the adjustable fastener 6 includes a second pressure rod 61, a second pressure plate 62 and a limiting plug 63. The second pressure plate 62 is arranged on the inner side of the gate-shaped reinforcement frame 4, and its two sides are respectively connected to the second pressure rod 61 and the limiting plug 63; 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, and a slot 111 adapted to the limiting plug 63 is arranged on the inner form 1 and the outer form 2. Similar to the installation and disassembly 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 plug 63 can be driven to approach the inner form 1 or the outer form 2, and then the limiting plug 63 is inserted into the slot 111, and the second pressure plate 62 is pressed against the inner form 1 or the outer form 2 to ensure the stability of the distance between the inner form 1 and the outer form 2, and prevent the concrete expansion form from causing it to deviate or skew.

[0045] In addition, a second guide rod 64 can be arranged on the door-shaped reinforcement frame 4. The second guide rod 64 and the second pressure rod 61 are both arranged transversely. 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-slip limit block is arranged on the end of the second guide rod 64 away from the second pressure plate 62. The second guide can provide a stable guide for the second pressure plate 62, so that the second pressure plate 62 can ensure the position accuracy of the limit plug 63 and the slot 111 during the rapid movement, so as to improve the construction efficiency.

[0046] Reference Figure 5 In order to facilitate the manufacture, transportation and installation of the casting template, the inner template 1 and the outer template 2 are connected by a single template 11 and a limiting insert 12. The connecting sides of adjacent single templates 11 are respectively configured with connecting grooves 112. The side opening width of the connecting groove 112 is smaller than the internal width. The two side ends of the limiting insert 12 are inserted into different connecting grooves 112 from the top. The top of the limiting insert 12 is configured with a lifting handle 13. Since the side opening width of the connecting groove 112 is smaller than the internal width, the limiting insert 12 cannot be separated from the side opening of the connecting groove 112, but can only be installed and removed by sliding in the vertical direction. However, once the installation is completed, the workers will not operate the lifting handle 13 at will, which can effectively ensure the connection stability of the adjacent single templates 11.

[0047] Taking a square concrete sewage tank as an example, the corners of its side walls are assembled by two single-piece templates 11. The connecting grooves 112 on the two single-piece templates 11 are located on the narrow side of the single-piece template 11 and on the large side of the single-piece template 11 (see Appendix 1). Figure 2 and the connecting grooves 112 on the monomer template 11 of the remaining parts are all constructed on the narrow side of the monomer template 11.

[0048] Reference Figure 5 The connecting groove 112 on the inner template 1 and the outer template 2 can be constructed with a cross-shaped or T-shaped (T-shaped not shown) structure in cross section to meet the above-mentioned "the side opening width of the connecting groove 112 is smaller than the internal width" requirement. Of course, technicians in this field can also make adaptive changes based on the cross-sectional shape provided above, as long as it meets the "side opening width of the connecting groove 112 is smaller than the internal width" described in this case.

[0049] During the construction process, the single formwork 11 is first connected to form the inner formwork 1 and the outer formwork 2 through the limiting insert 12. Then the triangular reinforcement frame 3 is 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 through the foundation anchor 5. Then the door-shaped reinforcement frame 4 is 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 through the adjustable fastener 6. Finally, the concrete pouring construction is carried out.

[0050] Compared with the prior art, the beneficial effect of the present invention is that the inner formwork 1 and the outer formwork 2 are reinforced by setting the triangular reinforcement frame 3 and the gate-shaped reinforcement frame 4, 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 a single formwork 11 and a limiting insert 12, which is convenient for assembly and disassembly, and improves the construction efficiency.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0052] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
