[0075] Each connection structure 3 is provided with a second connection buckle 34 and a second card slot that match each other in the outer direction toward the corresponding two long sides;

[0076] Every two adjacent strip structures are spliced ​​and connected by a plurality of sets of second connecting buckles 34 and second card slots that match each other and are arranged between a plurality of pairs of connecting structures 3 on two adjacent long sides.

[0077] like Figures 3 to 5 As shown, in some embodiments, each connecting buckle 2 includes a connecting plate 21 connected to a side of the corresponding steel structure frame 1 facing away from the corresponding plastic plate 5;

[0078] Each connecting plate 21 is provided with a clamping portion on one side facing the outer side of the corresponding steel structure frame 1;

[0079] Each clamping part includes two limit rods 29 capable of reciprocating along the corresponding first edge, and a limit clamping rod 25 connected to the two limit rods 29 in a movable pair;

[0080] Each limiting rod 25 is tubular, and a limiting rod 29 is provided at each opening at both ends. An elastic body is provided between the two corresponding limiting rods 29 to push the two corresponding limiting rods 29 out of the corresponding openings.

[0081] The two limiting rods 29 arranged in the same limiting rod 25 extend out of the ends of the corresponding limiting rods 25 and are both symmetrically wedge-shaped, and the farther away from the corresponding connecting plate 21, the shorter the length.

[0082] The connection structure 3 includes a connection structure body 31 and a connection block 313 connected in a revolving manner;

[0083] The rotary shaft 310 of the rotary pair formed by each connecting structure body 31 and the corresponding connecting block 313 is parallel to the first edges of the two steel structure frames 1 connected to the corresponding connecting structure 3, and a U-shaped clamping plate 32 is provided on the surface facing the two connecting buckles 2 connected to the corresponding connecting structure 3;

[0084] Each U-shaped clamping plate 32 includes two flat plate structures with a spacing not less than the length of the limiting clamping rod 25 of the corresponding connecting buckle 2, and the two plate structures are provided with a clamping hole 33 with a size larger than the cross section of the corresponding limiting rod 29 as a clamping slot matching the corresponding connecting buckle 2 to clamp the corresponding connecting buckle 2;

[0085] Each connecting structure body 31 is provided with a gear rod slide groove 35 and a matching gear rod slide rod 36 connected in a movable pair on one side facing the corresponding connecting block 313;

[0086] Each gear rod slide bar 36 can reciprocate along the normal direction of the steel structure frame 1 connected to the corresponding U-shaped clamping plate 32, and the side facing the corresponding connecting block 313 is a rack structure 37 that matches the semicircular fixed gear 311 set on the corresponding rotating shaft 310;

[0087] Each semicircular fixed gear 311 is coaxially arranged with the corresponding rotary shaft 310;

[0088] Each connecting structure body 31 is provided with a gear block limiting mechanism 39 at a position located on one side of the rotary shaft 310 .

[0089] In some embodiments, a connecting block 22 is provided between each limiting clamping rod 25 and the corresponding connecting plate 21;

[0090] The elastic body is a single spring 27, or a spring connecting block 26 connecting two springs 27;

[0091] Each spring connection block 26 is arranged at the middle position of the length of the corresponding limit clamp rod 25;

[0092] Each rotary shaft 310 and the corresponding semicircular fixed gear 311 are fixedly connected to the connecting block 313 through the rotating block 312, and are connected to the corresponding connecting structure body 31 through the bearings arranged at both ends to form a rotary pair connection;

[0093] Each gear bar slide groove 35 has an opening at one end facing away from the corresponding plastic plate 5 , and the corresponding gear bar slide rod 36 is provided with a handle 38 at one end located at the opening.

[0094] In some embodiments, each connecting plate 21 is provided with a push-pull rod slot 23 parallel to the corresponding limit clamping rod 25;

[0095] Each push-pull rod slot 23 is provided with two L-shaped push-pull rods 210 corresponding to the two limit rods 29 in the corresponding limit rod 25, and can reciprocate along the length direction of the corresponding limit rod 25;

[0096] Each L-shaped push-pull rod 210 includes a slider portion disposed in a corresponding push-pull rod slot 23, and a limit rod slot 28 passing through a side wall of a corresponding limit rod 25, and connecting a corresponding limit rod 29 and a connecting arm of a corresponding slider portion respectively;

[0097] Each connecting arm is connected to the corresponding sliding block to form an L-shaped structure.

[0098] In some embodiments, each gear block limiting mechanism 39 is an elastic plate with gear teeth that can mesh with the rack structure 37. When the corresponding gear bar slide 36 moves back and forth, it provides a minimum driving force test for driving the corresponding semicircular fixed gear 311 to rotate. When the force applied to the corresponding gear bar slide 36 is not greater than the elasticity of the corresponding gear block limiting mechanism 39, the relative position between the corresponding rack structure 37 and the corresponding semicircular fixed gear 311 is locked.

[0099] In practical applications, when it is necessary to splice every two steel structure frames 1 along the first edge, the connection structure 3 and the connection buckle 2 are first spliced, and the specific operation is as follows:

[0100] First, pull the L-shaped push-pull rod 210 of the connecting buckle 2 to be connected to the connecting structure 3, so that the L-shaped push-pull rod 210 drives the corresponding two limiting rods 29 to retract into the corresponding limiting clamping rod 25, then align the two clamping holes 33 of the U-shaped clamping plate 32 of the connecting structure 3 with the two ends of the corresponding limiting clamping rod 25, and release the L-shaped push-pull rod 210 at the same time. Under the elastic action of the spring 27, the two limiting rods 29 extend from the two ends of the limiting clamping rod 25 and clamp into the two clamping holes 33 of the U-shaped clamping plate 32, that is, the connecting structure 3 is connected with a connecting buckle 2;

[0101] Afterwards, the connecting buckle 2 of another steel structure frame 1 is connected to the already installed connecting structure 3, and the operation method is the same, except that the U-shaped clamping plate 32 of the original connecting structure main body 31 is replaced with the U-shaped clamping plate 32 of the connecting block 313 of the already installed connecting structure 3, so that the two steel structure frames 1 are firmly connected. At the same time, due to the design of the connecting buckle 2 and the connecting structure 3, this connection method is convenient and fast, which greatly improves the construction efficiency;

[0102] When the splicing angle needs to be adjusted, it can be achieved by adjusting the rotating mechanism inside the connecting structure 3. First, pull the handle 38 of the connecting structure 3, and the handle 38 drives the rack structure 37 to move along the gear rod slot 35. The movement of the rack structure 37 will drive the semicircular fixed gear 311 meshing with it to rotate. The rotation of the semicircular fixed gear 311 will then drive the connecting block 313 to rotate through the rotating shaft 310, thereby achieving the angle adjustment between the connecting structure body 31 and the connecting block 313. During the angle adjustment process, due to the meshing relationship between the rack structure 37 and the semicircular fixed gear 311, the adjusted angle can be ensured to be accurate and stable. When the desired angle is reached, release the handle 38, and the rack structure 37 will be limited at the desired position by the gear block limiting mechanism 39. At this time, the semicircular fixed gear 311 and the connecting block 313 will also remain at the current angle.

[0103] When it is necessary to splice two strip structures formed by multiple template units connected end to end in sequence through corresponding first edges, multiple sets of second connecting buckles 34 and second card slots that match each other are arranged between multiple pairs of connecting structures 3 on two adjacent long sides to splice and connect;

[0104] The structure of the second connecting buckle 34 is the same as the clamping part of each connecting buckle 2, and the second clamping groove plays the same role as the U-shaped clamping plate 32 clamping each connecting buckle 2, so that multiple strip structures can be connected in sequence to form a concrete formwork only through the same steps.

[0105] like Figure 1 and Figure 2 As shown, in some embodiments, each steel structure frame 1 includes a plurality of mutually perpendicular horizontal ribs and vertical ribs;

[0106] Each horizontal rib and each vertical rib are parallel to the first edge or the second edge respectively.

[0107] In some embodiments, within each steel structure frame 1 , any corresponding horizontally arranged horizontal ribs or vertical ribs facing upward are provided with a plurality of plastic plate connecting blocks 4 , which are connected to the corresponding plastic plates 5 through the plurality of plastic plate connecting blocks 4 .

[0108] like Figure 6 system Fig. 9As shown, in some embodiments, each plastic plate connecting block 4 includes a plastic plate connecting block body 41;

[0109] Each plastic plate connecting block body 41 is provided with a clamping block 42 on one side facing the corresponding plastic plate 5;

[0110] Each card block 42 is provided with a connection card block 43 on one side facing the plastic plate 5, which matches with the connection hole reserved on the horizontal rib or vertical rib of the corresponding steel structure frame 1, and can be smoothly inserted into the connection hole for fixing;

[0111] Each end of the connecting block 43 facing the corresponding plastic plate 5 includes two elastic second limiting rods 44 that can extend along the length direction of the corresponding horizontal rib or the corresponding vertical rib;

[0112] The ends of each of the two elastic second limiting rods 44 extending from the corresponding connecting block 43 are semicircular in cross section;

[0113] Each plastic plate 5 is provided with a plastic plate connecting block 52 at a position corresponding to each plastic plate connecting block 4;

[0114] Each plastic plate connecting block 52 includes a blind hole matching the portion of the plastic plate connecting block 4 extending toward the corresponding plastic plate 5;

[0115] Two elastic second limiting rods 44 of the corresponding connecting block 43 of each blind hole are provided with a plurality of pairs of connecting block slots 53 along the depth direction to form a movable connection with the corresponding connecting block 43 .

[0116] In some embodiments, the two elastic second limit rods 44 of each plastic plate connecting block 4 are arranged in a slide groove parallel to the length direction of the corresponding horizontal rib or the corresponding vertical rib on the corresponding connecting block 43, and a second spring 45 is provided between the two facing surfaces in the slide groove.

[0117] In some embodiments, a plurality of tension screw holes 54 are provided on the plastic plate body 51 of each plastic plate 5 facing the corresponding steel structure frame 1;

[0118] Each plastic plate 5 and each plastic plate connecting block 4 are made of high-strength glass fiber modified polypropylene material.

[0119] When it is necessary to splice each plastic plate 5 with the corresponding steel structure frame 1, first align the connecting block 42 of the plastic plate connecting block 4 with the connecting hole reserved on the steel structure frame 1 to ensure that the connecting block 42 can be smoothly inserted. Then, align the connecting block 43 with the corresponding plastic plate connecting block 52 on the plastic plate 5, and gently push the plastic plate connecting block 4 so that the connecting block 43 gradually enters the interior of the plastic plate connecting block 52. During this process, each of the two elastic second limiting rods 44 on both sides of the connecting block 43 will move inward under the pressure of the inner wall of the plastic plate connecting block 52 to compress the second spring 45. When each of the two elastic second limiting rods 44 moves to the position of the connecting block slot 53, due to the reset effect of the second spring 45, each of the two elastic second limiting rods 44 will quickly pop out and be stuck in the connecting block slot 53, thereby firmly fixing the plastic plate 5 on the steel structure frame 1. After completing the preliminary fixation of the plastic plate 5 and the steel structure frame 1, in order to further ensure the stability of the connection, a tension screw can be used for reinforcement.

[0120] First, select a tension screw of appropriate length, and pass one end of it through the tension screw hole 54 on the front side of the plastic plate body 51, and then align the other end with the corresponding reserved hole on the steel structure frame 1, and tighten it with force until both ends of the tension screw are firmly fixed on the two structural members. In this way, the tension of the tension screw can further enhance the connection strength between the plastic plate 5 and the steel structure frame 1, ensuring the stability and safety of the entire structure;

[0121] In practical applications, different numbers of plastic plate connecting blocks 4 and plastic plates 5 can be selected as needed for flexible splicing and combination to meet the needs of different occasions. At the same time, since the plastic plate connecting blocks 4 and plastic plates 5 are modularly designed, they can be easily replaced and repaired, which improves the convenience and economy of use.
