[0003] The development of prefabricated buildings and building industrialization is conducive to promoting the transformation of traditional construction methods to modern industrialized construction methods. The application of steel, bamboo, and plastic composite materials in the field of prefabricated buildings will bring good social benefits and economic value. At present, the assembly and installation steps between the various components of the prefabricated steel, bamboo, and plastic composite beam-slab structure are cumbersome, and the support of the various components after connection is poor, resulting in a small bearing capacity of the large-span secondary beam and main beam, which affects the strength of the beam-slab structure. For this reason, we introduce a prefabricated steel, bamboo, and plastic composite beam-slab structure and its construction method. Summary of the invention

[0004] The object of the present invention is to provide an assembled steel-bamboo-plastic composite beam-slab structure containing an auxiliary support seat to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: an assembled steel-bamboo-plastic composite beam-slab structure with an auxiliary support seat, comprising an I-shaped main beam, a secondary beam and a top plate, the I-shaped main beam is provided with a U-shaped groove for clamping the secondary beam, and the I-shaped main beam and the secondary beam are arranged vertically, and the auxiliary support seats are fixed on both sides of the U-shaped groove by first bolts;

[0006] After the second bolt on the top plate is locked with the buckle mechanism on the secondary beam, the lower end of the top plate is pressed against the top of the I-shaped main beam, the secondary beam and the auxiliary support seat;

[0007] After the two sides of the buckle mechanism extend through the slots on the side walls of the U-shaped groove, the two sides of the buckle mechanism are buckled on the first bolts under the driving of the second bolt locking, so as to realize the locking and fixing of the top plate, the secondary beam and the I-shaped main beam. At the same time, the secondary beam presses the diagonal brace on the auxiliary support seat downward to the horizontal part of the lower end of the I-shaped main beam, so as to realize the auxiliary support seat for the auxiliary support of the bottom of the secondary beam;

[0008] Two symmetrical groups of inclined plates are connected to the bottom of the top plate. When the second bolt is tightened, the top plate moves downward, and the locking piece inside the lower end of the inclined plate matches and locks with the positioning locking mechanism on the side of the secondary beam. The secondary beam provides auxiliary support to the top plate through the inclined plate, so that the top plate is further fixed to the secondary beam through the inclined plate.

[0009] Preferably, the auxiliary support seat comprises a U-shaped seat, an L-shaped support plate fixed to the upper ends of both sides of the U-shaped seat, and a plug-in block fixed to both sides of the U-shaped seat;

[0011] The L-shaped support plate is clamped on the side of the horizontal part of the upper end of the I-shaped main beam, and a limiting block is provided on the upper end of the top of the L-shaped support plate, which is used to be clamped in the limiting groove at the lower end of the top plate.

[0012] A pressure plate is provided on the top of the diagonal brace, and arc-shaped spring pieces are provided on both sides of the pressure plate, which are used to support the inner wall of the U-shaped seat to limit the downward movement of the diagonal brace. When the secondary beam presses down on the pressure plate, the arc-shaped spring pieces are squeezed inward by the inner wall of the U-shaped seat and deformed, so that the lower end of the diagonal brace passes through the U-shaped seat and moves downward until the lower end of the diagonal brace is inserted into the oblique slot on the horizontal part of the lower end of the I-shaped main beam.

[0013] Preferably, a rectangular groove is provided on the secondary beam, a middle protrusion is provided at the center of the bottom thereof, and a sliding groove is provided on the upper side of the middle of the rectangular groove;

[0015] The second bolt passes through the top plate and the secondary beam and is screwed to the middle of the lifting block. The slot is connected to the corresponding through slot. An elastic sheet is connected to the inner side of the snap plate, which is used to contact the middle protrusion to pop the bottom of the snap plate out of the rectangular slot, and make the bottom of the snap plate extend through the slot to between the front and rear two groups of plug-in blocks in the through slot;

[0016] At this time, when the second bolt is locked, the lifting block drives the snap plate to move up, so that the outer side of the bottom of the snap plate moves up between the front and rear groups of plug-in blocks until the outer side of the bottom of the snap plate is snapped on the first bolt.

[0017] Preferably, the top plate includes a top steel plate and a bottom steel plate distributed up and down and a bamboo-plastic plate filled between the top steel plate and the bottom steel plate;

[0019] The inner and outer sides of the lower end of the inclined plate are respectively provided with a first opening groove and a second opening groove, and the first opening groove and the second opening groove are communicated;

[0020] The locking member comprises a horizontal seat and a locking seat connected to the upper end of the inner side of the horizontal seat, and a connecting shaft passes through the outer end of the horizontal seat, and both ends of the connecting shaft are inserted into the vertical grooves on the side wall of the second opening groove;

[0022] The vertical plates are fixedly connected to the side walls of the secondary beams, the abutment plates are located between the two groups of vertical plates, and the height of the abutment plates is lower than the height of the horizontal axis;

[0023] When the second bolt is locked, the top plate drives the inclined plate to move downward, so that the lower end of the inclined plate is stuck between the two sets of vertical plates, and the horizontal shaft enters the first opening groove, pushing the locking seat upward to rotate, so that the horizontal shaft moves over the locking seat;

[0024] Subsequently, the top of the abutment plate contacts the lower end of the horizontal seat, pushing the horizontal seat upward, and when the lower end of the inclined plate contacts the upper end of the bottom plate, the horizontal seat drives the locking seat to lock the horizontal shaft just at the top of the first opening groove.

[0030] The top plate moves downward, and the locking piece inside the lower end of the inclined plate is matched and locked with the positioning locking mechanism on the side of the secondary beam.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention locks the snap mechanism on the secondary beam through the second bolt, so that the two sides of the snap mechanism are snapped on the first bolt, thereby realizing the locking and fixation of the top plate, the secondary beam and the I-shaped main beam. At the same time, the secondary beam presses the diagonal brace on the auxiliary support seat downward to the horizontal part of the lower end of the I-shaped main beam, thereby realizing the auxiliary support of the bottom of the secondary beam by the auxiliary support seat; and when the second bolt is locked, the top plate moves downward, and the locking piece inside the lower end of the inclined plate matches and locks with the positioning locking mechanism on the side of the secondary beam, and the secondary beam realizes auxiliary support for the top plate through the inclined plate, so that the top plate is further fixed to the secondary beam through the inclined plate.

Obviously, the described embodiments are only 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.

[0050] See also Figure 1-16 , the present invention provides a technical solution:

[0051] Embodiment 1:

[0052] An assembled steel-bamboo-plastic composite beam-slab structure, comprising an I-shaped main beam 1, a secondary beam 8 and a top plate 9, wherein the I-shaped main beam 1 is provided with a U-shaped groove 2 for clamping the secondary beam 8, and the I-shaped main beam 1 and the secondary beam 8 are arranged vertically, and auxiliary support seats 6 are fixed on both sides of the U-shaped groove 2 by first bolts 7;

[0053] like Figure 2 , 4 As shown in FIG. 5 , the auxiliary support seat 6 includes a U-shaped seat 61, an L-shaped support plate 63 fixed to the upper ends of both sides of the U-shaped seat 61, and a plug-in block 62 fixed to both sides of the U-shaped seat 61;

[0054] The plug-in block 62 is inserted into the through slot 4 on the side of the U-shaped slot 2, and the plug-in blocks 62 at both ends of the through slot 4 are locked and fixed by the first bolts 7. The through slot 4 is arranged on the vertical part in the middle of the I-shaped main beam 1;

[0055] The L-shaped support plate 63 is clamped on the horizontal side of the upper end of the I-shaped main beam 1, and a limit block 64 is provided on the top upper end of the L-shaped support plate 63, which is used to be clamped in the limit groove at the lower end of the top plate 9.

[0056] A pressure plate 66 is provided on the top of the diagonal brace 67, and arc-shaped spring pieces 65 are provided on both sides of the pressure plate 66, which are used to support the inner wall of the U-shaped seat 61 to limit the downward movement of the diagonal brace 67. When the secondary beam 8 presses down on the pressure plate 66, the arc-shaped spring pieces 65 are squeezed inward by the inner wall of the U-shaped seat 61 and deformed, so that the lower end of the diagonal brace 67 passes through the U-shaped seat 61 and moves downward until the lower end of the diagonal brace 67 is inserted into the diagonal slot 3 on the horizontal part of the lower end of the I-shaped main beam 1.

[0057] After the second bolt 10 on the top plate 9 is locked with the buckle mechanism on the secondary beam 8, the lower end of the top plate 9 is pressed against the top of the I-shaped main beam 1, the secondary beam 8 and the auxiliary support seat 6;

[0058] After the two sides of the buckle mechanism extend through the slots 5 on the side walls of the U-shaped slot 2, the two sides of the buckle mechanism are buckled on the first bolts 7 under the driving of the second bolts 10 to achieve the locking and fixing of the top plate 9, the secondary beam 8 and the I-shaped main beam 1. At the same time, the secondary beam 8 presses the diagonal brace 67 on the auxiliary support seat 6 downward to the horizontal part of the lower end of the I-shaped main beam 1, so that the auxiliary support seat 6 can provide auxiliary support to the bottom of the secondary beam 8;

[0059] The secondary beam 8 is provided with a rectangular groove 12, a middle protrusion 17 is provided at the center of the bottom thereof, and a sliding groove 15 is provided at the upper middle side of the rectangular groove 12;

[0060] like Figure 6 , 8 As shown in FIG. 9 , the buckle mechanism includes a lifting block 14, connecting ears 19 provided on both sides of the lifting block 14, and a buckle plate 11 movably connected between two groups of connecting ears 19 on the same side through a pin shaft 13, and a sliding protrusion 18 is provided in the middle of the front and rear ends of the lifting block 14, which is slidably connected in the slide groove 15;

[0061] The second bolt 10 penetrates the top plate 9 and the secondary beam 8 and is screwed to the middle of the lifting block 14. The slot 5 is connected to the corresponding through slot 4. An elastic sheet 16 is connected to the inner side of the snap plate 11, which is used to contact the middle protrusion 17 to pop the bottom of the snap plate 11 out of the rectangular slot 12, and make the bottom of the snap plate 11 extend through the slot 5 to between the front and rear two groups of plug-in blocks 62 in the through slot 4;

[0062] At this time, when the second bolt 10 is tightened, the lifting block 14 drives the snap plate 11 to move upward, so that the bottom outer side of the snap plate 11 moves upward along between the front and rear groups of plug-in blocks 62 until the bottom outer side of the snap plate 11 is snapped onto the first bolt 7.

[0063] like Fig.10 As shown, the top plate 9 includes a top steel plate 91 and a bottom steel plate 93 distributed up and down, and a bamboo plastic plate 92 filled between the top steel plate 91 and the bottom steel plate 93;

[0064] The top of the top plate 9 is installed in the inverted T-shaped tube 95 through a connecting pin 97, and the upper end of the inverted T-shaped tube 95 passes through the bottom steel plate 93 and extends into the bamboo plastic board 92, and the lower end of the countersunk bolt 94 on the top steel plate 91 passes through the top steel plate 91, the bottom steel plate 93 and the bamboo plastic board 92 in sequence and is screwed to the bottom sides of the inverted T-shaped tube 95.

[0065] The inner and outer sides of the lower end of the inclined plate 96 are respectively provided with a first opening groove 961 and a second opening groove 962, and the first opening groove 961 and the second opening groove 962 are connected;

[0066] Two symmetrical groups of inclined plates 96 are connected to the bottom of the top plate 9. When the second bolt 10 is tightened, the top plate 9 moves downward, and the locking piece inside the lower end of the inclined plate 96 is matched and locked with the positioning locking mechanism on the side of the secondary beam 8. The secondary beam 8 provides auxiliary support for the top plate 9 through the inclined plate 96, so that the top plate 9 is further fixed to the secondary beam 8 through the inclined plate 96.

[0067] like Fig.11 and 12 As shown, the locking member includes a horizontal seat 964 and a locking seat 963 connected to the inner upper end of the horizontal seat 964, and a connecting shaft 965 passes through the outer end of the horizontal seat 964, and its two ends are inserted into the vertical grooves 966 on the side wall of the second opening groove 962;

[0068] like Figure 7 and 13 As shown in Figure 16, the positioning and locking mechanism includes a bottom plate 21 fixed to the bottom of the side of the secondary beam 8, vertical plates 22 connected to both sides of the upper end of the bottom plate 21, a horizontal shaft 23 connected between the two groups of vertical plates 22, and a support plate 24 fixed on the side wall of the secondary beam 8;

[0069] The vertical plates 22 are fixedly connected to the side walls of the secondary beam 8, and the abutment plate 24 is located between the two groups of vertical plates 22, and the height of the abutment plate 24 is lower than the height of the horizontal axis 23;

[0070] When the second bolt 10 is tightened, the top plate 9 drives the inclined plate 96 to move downward, so that the lower end of the inclined plate 96 is stuck between the two sets of vertical plates 22, and the horizontal shaft 23 enters the first opening groove 961, pushing the locking seat 963 upward to rotate, so that the horizontal shaft 23 moves over the locking seat 963;

[0071] Subsequently, the top of the abutment plate 24 contacts the lower end of the horizontal seat 964, pushing the horizontal seat 964 upward. When the lower end of the inclined plate 96 contacts the upper end of the bottom plate 21, the horizontal seat 964 drives the locking seat 963 to lock the horizontal shaft 23 at the top of the first opening groove 961.

[0072] The present invention also provides a construction method for an assembled steel-bamboo-plastic composite beam-slab structure, which specifically comprises the following steps:

[0073] S1. Insert the plug-in block 62 on the auxiliary support seat 6 into the through slot 4 on the side of the U-shaped slot 2, and lock and fix the corresponding two groups of plug-in blocks 62 by the first bolt 7, so that the two groups of plug-in blocks 62 are respectively located at both ends of the through slot 4, thereby fixing the auxiliary support seat 6 on both sides of the U-shaped slot 2;

[0074] S2, inserting the secondary beam 8 into the U-shaped groove 2, and at the same time inserting the secondary beam 8 into the corresponding U-shaped seat 61 of the auxiliary support seat 6;

[0075] S3, placing the top plate 9 on the top of the I-shaped main beam 1, the secondary beam 8 and the auxiliary support seat 6, and then tightening the second bolt 10 so that the lower end of the top plate 9 is pressed against the top of the I-shaped main beam 1, the secondary beam 8 and the auxiliary support seat 6;

[0076] At the same time, the lifting block 14 drives the snap plate 11 to move upward, so that the outer side of the bottom of the snap plate 11 moves upward along the front and rear groups of plug-in blocks 62 until the outer side of the bottom of the snap plate 11 is snapped onto the first bolt 7;

[0077] The top plate 9 moves downward, and the locking member inside the lower end of the inclined plate 96 matches and locks with the positioning locking mechanism on the side of the secondary beam 8.

[0078] Specifically, when in use, the lower end of the diagonal support 67 is extended through the bottom of the U-shaped seat 61 to a certain distance, so that the arc-shaped spring piece 65 is supported on the inner wall of the U-shaped seat 61 to limit the downward movement of the diagonal support 67 (such as Figure 4 status shown);

[0079] like Figure 2 and 3As shown, the plug-in block 62 on the auxiliary support seat 6 is inserted into the through slot 4 on the side of the U-shaped slot 2, and the corresponding two groups of plug-in blocks 62 are locked and fixed by the first bolt 7, so that the two groups of plug-in blocks 62 are respectively located at both ends of the through slot 4, thereby fixing the auxiliary support seat 6 on both sides of the U-shaped slot 2;

[0080] At this time, the L-shaped support plate 63 is stuck on the side of the horizontal part of the upper end of the I-shaped main beam 1;

[0081] The secondary beam 8 is inserted into the U-shaped groove 2. At this time, the outer side of the bottom of the snap plate 11 contacts the side wall of the U-shaped groove 2, so that the outer side of the bottom of the snap plate 11 is squeezed and retracted into the rectangular groove 12 of the secondary beam 8. At this time, the elastic sheet 16 is in a compressed and deformed state, and has an elastic force on the snap plate 11;

[0082] When the outer side of the bottom of the snap plate 11 moves to the position of the slot 5, the bottom of the snap plate 11 pops out of the rectangular slot 12 under the elastic force of the elastic sheet 16, and the bottom of the snap plate 11 extends through the slot 5 to between the front and rear groups of plug-in blocks 62 in the through slot 4, and the first bolt 7 is located above the outer side of the bottom of the snap plate 11;

[0083] When the secondary beam 8 is inserted into the U-shaped groove 2, the secondary beam 8 is also inserted into the corresponding U-shaped seat 61 of the auxiliary support seat 6. At this time, when the secondary beam 8 presses down the pressure plate 66, the arc-shaped spring piece 65 is squeezed by the inner wall of the U-shaped seat 61 and deforms inward, so that the lower end of the diagonal support 67 penetrates the U-shaped seat 61 and moves downward until the lower end of the diagonal support 67 is inserted into the diagonal slot 3 on the horizontal part of the lower end of the I-shaped main beam 1.

[0084] In this way, the secondary beam 8 presses the diagonal brace 67 on the auxiliary support seat 6 downward to the horizontal part of the lower end of the I-shaped main beam 1, and the diagonal brace 67 supports the U-shaped seat 61, thereby realizing the auxiliary support of the auxiliary support seat 6 to the bottom of the secondary beam 8;

[0085] Then, the top plate 9 is placed on the top of the I-shaped main beam 1, the secondary beam 8 and the auxiliary support seat 6, and the limit block 64 at the top end of the L-shaped support plate 63 is stuck in the limit groove at the lower end of the top plate 9 to achieve the positioning effect when the top plate 9 is installed, and at the same time, the lower end of the inclined plate 96 is stuck between the two groups of vertical plates 22;

[0086] Then, the second bolt 10 is tightened, so that the lower end of the top plate 9 is pressed against the top of the I-shaped main beam 1, the secondary beam 8 and the auxiliary support seat 6. At the same time, the second bolt 10 passes through the top plate 9 and the secondary beam 8 and is screwed to the middle of the lifting block 14. The lifting block 14 drives the snap plate 11 to move upward, so that the outer side of the bottom of the snap plate 11 moves upward along the front and rear two groups of plug-in blocks 62 until the outer side of the bottom of the snap plate 11 is snapped on the first bolt 7.

[0087] In this way, when the second bolt 10 is locked, the two sides of the buckle mechanism are buckled on the first bolt 7, so as to achieve the purpose of locking and fixing the top plate 9, the secondary beam 8 and the I-shaped main beam 1;

[0088] When the second bolt 10 is tightened, the top plate 9 drives the inclined plate 96 to move downward, and the lower end of the inclined plate 96 moves downward along the space between the two sets of vertical plates 22, and the horizontal shaft 23 enters the first opening groove 961, pushing the locking seat 963 upward to rotate (such as Fig.14 As shown in the state), the lower end of the inclined plate 96 continues to move downward, so that the horizontal shaft 23 moves over and moves to the top of the locking seat 963 (as shown in the state). Fig.15 status shown);

[0089] Subsequently, the top of the abutment plate 24 contacts the lower end of the horizontal seat 964, pushing the horizontal seat 964 upward. When the lower end of the inclined plate 96 contacts the upper end of the bottom plate 21, the horizontal seat 964 drives the locking seat 963 to lock the horizontal shaft 23 at the top of the first opening groove 961 (such as Fig.16 status shown).

[0090] In this way, after the top plate 9 moves downward, the locking piece inside the lower end of the inclined plate 96 is matched and locked with the positioning locking mechanism on the side of the secondary beam 8. The secondary beam 8 provides auxiliary support for the top plate 9 through the inclined plate 96, so that the top plate 9 is further fixed to the secondary beam 8 through the inclined plate 96.

[0091] 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.
