[0047] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Reference Figure 1-Figure 4 The embodiment of the present application discloses a template assembly structure with a reinforcement structure for a box culvert, which includes two sets of outer corner template groups, two sets of inner corner template groups, and a reinforcement mechanism for fixing each outer corner template group and the inner corner template group.

[0049] The outer corner template group includes a first A-type template 11, a standard template 2 and a B-type template 3 which are arranged vertically and connected in sequence from top to bottom, and a reinforcement mechanism is used to fix the top of the first A-type template 11 and the outer side of the B-type template 3;

[0050] The inner corner formwork group includes two second A-type formworks 12 arranged orthogonally and an axillary corner formwork 4 connected between the two second A-type formworks 12 . The reinforcement mechanism is also used to fix the opposite sides of the two second A-type formworks 12 .

[0051] In addition, the two groups of outer corner formwork groups are located outside the two groups of inner corner formwork groups, the second A-type formwork 12 vertically arranged in the inner corner formwork group is arranged in parallel with the first A-type formwork 11 in the outer corner formwork group, and a "U"-shaped casting cavity 5 is enclosed between the two groups of inner corner formwork groups and the two groups of outer corner formwork groups.

[0052] Wherein, the first A-type template 11 and the second A-type template 12 both include a standard template 2 and a first slide groove 61, and the first slide groove 61 is connected to the side of the standard template 2;

[0053] The B-type template 3 includes a standard template 2 and a second slide groove 62 , and the second slide groove 62 is connected to the outer side surface of the standard template 2 .

[0054] In this way, when casting the box culvert, after assembling multiple groups of outer corner formwork groups and inner corner formwork groups, the gap between the outer corner formwork group and the inner corner formwork group can be controlled, and then the first A-type formwork 11, the second A-type formwork 12 and the B-type formwork 3 can be fixed with a reinforcement mechanism, so that a casting cavity 5 with a firm outer structure can be formed, which is convenient for casting and molding the box culvert; and in the process of fixing the outer corner formwork group and the inner corner formwork group, the reinforcement mechanism will not pass through the casting cavity 5, that is, there will be no holes on the box culvert after molding, which can effectively improve the problem of water leakage at the hole position caused by fixing with tension screws in the current technology. Moreover, the outer corner formwork group, the inner corner formwork group and the reinforcement mechanism can be assembled in an assembled form, and after casting and molding, they can be easily disassembled and reused, which solves the problems of heavy weight, inconvenient movement and low installation and disassembly efficiency of traditional integrated formwork, and also solves the problems of low turnover rate of wooden formwork and low concrete molding quality, which can greatly reduce construction costs.

[0055] In addition, refer to Figure 1 , the reinforcement mechanism includes:

[0056] A cross bar 71 is arranged along the arrangement direction of the outer corner template group and the inner corner template group;

[0057] The movable fixing member is anti-slip and slidably arranged in the first slide groove 61 and the second slide groove 62;

[0058] A close connection member is used to fix the movable fixing member in the first slide groove 61 close to the cross bar 71 to the cross bar 71. Specifically, the close connection member is used to connect the first A-type template 11 in the outer corner template group and the vertical second A-type template 12 in the inner corner template group; and

[0059] The long-distance connecting member is used to fix the movable fixing member in the second slide groove 62 and the first slide groove 61 away from the cross bar 71 to the cross bar 71. Specifically, the long-distance connecting member is used to connect the horizontal second A-type formwork 12 in the inner corner formwork group and the B-type formwork 3 in the outer corner formwork group.

[0060] Among them, refer to Figure 5 The movable fixing part includes a stopper plate 81 which is anti-slip and slidingly arranged in the first slide groove 61 or the second slide groove 62, and two parallel connecting plates 82 which are fixed to the bottom plate. The groove types of the first slide groove 61 and the second slide groove 62 are both T-shaped grooves. The two connecting plates 82 are spaced apart and located in the middle of the stopper plate 81. A through hole 821 is penetrated at one end of the connecting plate 82 away from the stopper plate 81.

[0061] Reference Figure 1 The cross bar 71 is provided with a plurality of fixing holes 711 spaced apart along the length direction thereof, and the close-distance connecting member is provided as a first latch 712 which is jointly provided in the through hole 821 and one of the fixing holes 711 .

[0062] Remote connectors include:

[0063] The diagonal brace 72 has a movable fixing piece connected to one end and is mounted on the cross bar 71 through a close connection piece; the other end is provided with a plurality of adjustment holes 721 spaced apart along its length direction and connected to the movable fixing piece in the second slide slot 62 or the movable fixing piece in the first slide slot 61 away from the cross bar 71;

[0064] The second latch 722 is plugged and matched with the support adjustment hole 721 and the through hole 821 .

[0065] In addition, refer to Figure 1 and Figure 5 At least two adjusting screws 811 are threadedly provided on the connecting plate 82. On the one hand, the movable fixing part can be fixed to the end of the diagonal support rod 72 by the adjusting screws 811; on the other hand, by tightening the adjusting screws, the support plate 81 can be locked in the first slide groove 61 or the second slide groove 62, so as to facilitate locking and positioning of the outer corner template group and the inner plate template group after the cross bar 71 is fixed.

[0066] In this way, the outer corner formwork group and the inner plate formwork group can be locked on the crossbar 71 independently by means of the combination of the long-distance connector and the short-distance connector, and this locking structure will not cross the casting cavity 5, which can effectively ensure the casting quality of the box culvert. At the same time, the movable fixing member can slide in the first slide groove 61 and the second slide groove 62, so that the fixing system can move longitudinally along the box culvert, such as Figure 7 As shown, the influence of the vertical reinforcement of the side wall can be avoided and the installation efficiency can be improved.

[0067] Moreover, a plurality of fixing holes 711 are provided on the crossbar 71, and the movable fixing parts can be fixed at different positions on the crossbar 71 through the first latch 712, that is, the outer corner formwork group and the inner plate formwork group can be independently provided at different positions on the crossbar 71, which is suitable for the pouring of box culverts with different wall thicknesses and different sizes, so that the reusability of the assembled formwork and reinforcement system of the present application is greatly improved. Furthermore, by providing a plurality of adjustment holes 721 on the diagonal support rod 72 and supplemented with the second latch 722 matched therewith, the installation state of the outer corner formwork group can also be adjusted.

[0068] In order to further improve the application of this application for the casting of box culverts of various sizes and models, refer to Figure 6 The diagonal support rod 72 and the cross bar 71 are both configured as an outer rod 91 and at least one inner rod 92, the inner rod 92 is slidably disposed in the outer rod 91, the inner rod 92 has a plurality of adjustment holes 921 spaced apart along its length direction, the outer rod 91 has a positioning hole 911 at one end close to the inner rod 92, and a third latch 93 is inserted into the positioning hole 911 and is plugged into the adjustment hole 921. In a specific configuration, the inner rod 92 and the outer rod 91 can be a square tube or a round tube, and the inner rod 92 is provided at both ends of the outer rod 91 in the cross bar 71.

[0069] In this way, the actual length of the cross bar 71 or the diagonal support bar 72 can be adjusted by sliding the inner rod 92 in the outer rod 91. After the adjustment is completed, the third pin 93 is inserted into the corresponding adjustment hole 921 to lock the inner rod 92 after the length adjustment is completed.

[0070] Specifically, refer to Figure 2-Figure 4 The above-mentioned standard template 2 is arranged in a rectangular shape, and a plurality of bolt holes 21 are provided on the peripheral side of the standard template 2, and a back rib 22 is connected to the back side. The cross section of the axillary corner template 4 is an isosceles trapezoid, and the upper bottom of the cross section has a back rib 22, and the hypotenuse of the cross section has a plurality of bolt holes 21. The plurality of bolt holes 21 on the long side of the standard template 2 correspond one to one with the plurality of bolt holes 21 on the hypotenuse of the axillary corner template 4. In this way, the back rib 22 can greatly improve the rigidity of the standard template 2 as a whole, and can effectively limit the occurrence of mold expansion; the setting of a plurality of bolt holes 21 facilitates the self-bolting assembly of each inner corner template group and the outer corner template group, which greatly improves the modular effect of the assembly template and reinforcement system of the present application, and is extremely practical.

[0071] The implementation principle of a template assembly structure with a reinforcement structure for a box culvert in the embodiment of the present application is:

[0072] When pouring the box culvert, multiple groups of outer corner formwork groups and inner corner formwork groups can be assembled and fixed with a reinforcement mechanism. In the process of fixing the outer corner formwork groups and the inner corner formwork groups, the long-distance connector and the short-distance connector will not pass through the pouring cavity 5, that is, there will be no holes on the box culvert after forming, which can effectively improve the problem of water leakage at the hole position caused by fixing with tension screws in the current technology. Moreover, the outer corner formwork group, the inner corner formwork group and the reinforcement mechanism can be assembled in an assembled form. Similarly, after pouring and forming, the formwork can be easily disassembled and reused, which solves the problems of heavy, inconvenient to move and low installation and disassembly efficiency of traditional integrated formworks. At the same time, it also solves the problems of low turnover rate of wooden formworks and low concrete forming quality, which can greatly reduce construction costs.
