Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a large-span assembled mulch board dense joint anti-leakage slurry construction device. Background Art

[0002] Plywood, also known as laminated panels or semi-prefabricated panels, is a building material used in residential and industrial construction. It is mainly used with double skin walls to build monolithic buildings. It is light in weight and easy to install on site using cranes with lower load-bearing capacity.

[0003] The mulch board is usually composed of a 40-60 mm thick concrete slab, longitudinal and transverse reinforcements and longitudinal bending truss bars. The truss bars are composed of welded concrete steel bars, a visible upper chord, two lower chords injected with concrete, and diagonal connecting rods between the upper and lower chords. The rough surface of the composite board and the diagonal connecting rods of the truss bars ensure the final bonding between the prefabricated components and the cast-in-place concrete. When it comes to the splicing of large-span mulch boards, there is a splicing gap between two adjacent mulch boards. The existing sealing and leak-proofing method is to directly pour concrete after the installation is completed so that it can be connected and closed, thereby making the splicing seam leak-proof.

[0004] However, since concrete will both shrink and expand during the solidification process, in most cases, the concrete filled inside will be more or less squeezed and broken due to the physical properties of the connecting structure, which will affect the integrity of the joints of the mulberry boards. As a result, during long-term use, liquid will easily penetrate and remain inside, affecting the effectiveness and stability of the seal. At the same time, the concrete and the mulberry boards are only connected by planar bonding, which lacks stability and firmness, making it difficult to combine the concrete at the joints and the mulberry boards into an integral structure. As a result, there is much room for improvement in the sealing stability of the existing prefabricated mulberry board joint seam leakage prevention construction device. In this regard, the present invention provides a large-span prefabricated mulberry board close-jointed seam leakage prevention construction device to solve the above-mentioned problem.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0033] See also Figures 1 to 7 The present invention provides a technical solution: a large-span assembled mulch board joint anti-leakage slurry construction device, comprising a plurality of mulch board bodies 1, a support frame 2 and a connecting frame beam 3, a plurality of fixing plates 4 fixedly connected to the bottom of the corresponding mulch board body 1 are fixed on both sides of the connecting frame beam 3, a basic sealing component 500 is installed on the top of the connecting frame beam 3, a connecting component 600 is installed on the inner side of the connecting frame beam 3, and a sealing reinforcement component 700 is installed on the outer side of the mulch board body 1;

[0034] In the above-mentioned embodiment, through the coordinated use of the mulch board body 1, the support frame 2, the connecting frame beam 3, the fixing plate 4 and the basic sealing component 500, the basic sealing property of the mulch board connection can be ensured, so that it can meet the demand for anti-leakage slurry use. Under the coordinated action of the connecting component 600, the adjacent mulch boards can be effectively connected after the concrete solidifies. Through the use of the sealing reinforcement component 700, the sealing performance of the basic sealing component 500 can be increased, and the joints can be sealed in multiple layers through the special-shaped sealing structure to prevent liquid from entering. Moreover, through the layout of the structure, it has a certain extension and activity ability, avoiding cracking caused by hard extrusion, so that the concrete after solidification can have excellent sealing performance.

[0035] It should be noted that the support frame 2 is fixedly installed at the bottom of the corresponding connecting frame beam 3, the top of the connecting frame beam 3 is open, and the connecting frame beam 3 is fixedly installed between the bottoms of two adjacent mulberry board bodies 1 through the fixing plates 4 on both sides, so that the mulberry board body 1 can be constructed, installed and fixed normally.

[0036] In this embodiment, the connection assembly 600 is a structure used to increase the integrity of the connection of large-span plywood.

[0037] like Figure 1 and Figure 4 As shown, the connection assembly 600 includes a plurality of connection plates 601 fixedly mounted on the inner bottom wall of the connection frame beam 3, two connection pieces 602 are fixed on the top of the connection plates 601, a first semicircular piece 603 is fixed on the top of the connection piece 602 on one side, and a second semicircular piece 604 is fixed on the top of the connection piece 602 on the other side, and a plurality of connection blocks 605 are fixed on the bottom of the mulberry board body 1, a connection groove 606 is provided at the bottom of the connection block 605, and connecting holes 607 are provided on the front and back sides of the connection block 605.

[0038] It should be noted that the corresponding first semicircular parts 603 and second semicircular parts 604 are symmetrically distributed, and the diameter of the second semicircular parts 604 is larger than the diameter of the first semicircular parts 603, so that the first semicircular parts 603 and the second semicircular parts 604 can move independently through the diameter difference without affecting the movement of each other, thereby adapting the concrete when the concrete shrinks or expands. There are two groups of connecting plates 601 inside each connecting frame beam 3, and two groups of connecting blocks 605 are fixed at the bottom of each mulberry board body 1, which correspond to the positions of the corresponding group of connecting plates 601. The connecting groove 606 can be used for the corresponding first semicircular parts 603 and the second semicircular parts 604 to be plugged in at the same time, so that the corresponding first semicircular parts 603 and the second semicircular parts 604 can be plugged in on the inner side of the connecting groove 606.

[0039] In addition, the bottom of the connecting hole 607 is open, and the interior of the connecting hole 607 is connected to the interior of the corresponding connecting groove 606, so that concrete can enter the interior of the connecting groove 606 through the connecting hole 607 for filling, so that after solidification, it can be limited on the inner side of the first semicircular piece 603 and the second semicircular piece 604, thereby improving the integrity and connection stability of the leak-proof structure.

[0040] In this embodiment, the sealing reinforcement assembly 700 is a structure used to enhance the sealing capability and increase the integrity.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the sealing reinforcement component 700 includes two adaptation grooves 701 provided at the bottom of the mulberry board body 1, the inner side of the adaptation groove 701 is filled with a sponge layer 702, the left and right sides of the mulberry board body 1 are provided with oblique grooves 703 with an opening at the top, the right side of the mulberry board body 1 is fixed with a first extrusion plate 704, the inner bottom wall of the connecting frame beam 3 is fixed with two groups of first screw rods 705, the outer side of the first screw rod 705 is threadedly connected with a first nut 706, the left side of the mulberry board body 1 is fixed with a second extrusion plate 707, and the top of the first extrusion plate 704 is provided with an activity hole 708 for the corresponding first screw rod 705 to move;

[0042] like Figure 5 , Figure 6 and Figure 7 As shown, two docking grooves 709 are provided on the top of the mulberry board body 1, and the inner side of the docking groove 709 is coated with sealant 710, an extrusion block 711 is inserted between the inner sides of two adjacent docking grooves 709, a shielding plate 712 is fixed on the top of the extrusion block 711, and two first sealing members 713 are bonded to the bottom of the shielding plate 712, two triangular grooves 714 are provided on the top of the mulberry board body 1, and two second sealing members 715 are bonded to the bottom of the shielding plate 712, a bottom plate 716 is fixedly installed between the opposite sides of two adjacent support frames 2, an embedding groove 717 is provided on the top of the bottom plate 716, an extrusion pad 718 is bonded to the inner side of the embedding groove 717, and a cylindrical strip 719 is bonded to the top of the extrusion pad 718.

[0043] It should be noted that a plurality of second screws 720 are fixed on the inner side of the docking groove 709, and the outer side of the second screw 720 is threadedly connected with a second nut 721. The top end of the second screw 720 passes through the corresponding extrusion block 711 and the baffle plate 712 in sequence and extends to the outside. The second nut 721 abuts against the top of the corresponding baffle plate 712, so that the cooperation between the second screw 720 and the second nut 721 can reinforce the positioning of the baffle plate 712 and exert a downward extrusion force, so that the sealing structure is pressed more tightly.

[0044] In addition, the front and back sides of the adaptation groove 701 are both open, so that the corners of the mulberry board body 1 close to the adaptation groove 701 can move to a certain extent, which is convenient for adaptation with concrete. The front and back sides of the oblique groove 703 are both open, so that concrete can be filled between the oblique groove 703 and the inside of the connecting frame beam 3. The first screw rod 705 on the left side of the same connecting frame beam 3 penetrates the top of the corresponding first extrusion plate 704, and the first screw rod 705 on the right side of the same connecting frame beam 3 penetrates the inside of the corresponding movable hole 708 and the top of the second extrusion plate 707, so that the first extrusion plate 704 and the second extrusion plate 707 can be connected and fixed to the corresponding first screw rod 705, and the corresponding first screw rod 705 can move inside the movable hole 708, which is convenient for adaptation with solidified concrete.

[0045] At the same time, the docking groove 709 is opened on one side close to the adjacent mulberry board main body 1, and the left and right sides of the docking groove 709 are opened, so that the sealant 710 inside the two adjacent docking grooves 709 can be evenly coated, and the baffle plate 712 is fixedly installed between the tops of the two adjacent mulberry board main bodies 1, so that the connecting seams of the mulberry board main bodies 1 can be shielded and sealed by the baffle plate 712.

[0046] In addition, the bottom of the first seal 713 abuts against the top of the mulberry board body 1, and the second seal 715 is filled in the inner side of the corresponding triangular groove 714, so that the cooperation of the first seal 713 and the second seal 715 can play a stable sealing role in the joint seam of the mulberry board body 1 to prevent external liquid from entering. Two cylindrical grooves are provided at the bottom of the mulberry board body 1, and the opposite sides of the two adjacent cylindrical grooves are both open. The cylindrical strip 719 is inserted between the inner sides of the corresponding two cylindrical grooves, so that the cylindrical strip 719 can be inserted in the inner side of the cylindrical groove to seal the bottom connecting seam of the mulberry board body 1.

[0047] In this embodiment, the basic sealing assembly 500 is a structure used to perform leak-proof sealing on the joints of the plywood body 1 .

[0048] like Figure 1 and Figure 5 As shown, the basic sealing assembly 500 includes two first sealing grooves 501 opened at the top of the connecting frame beam 3, the inner side of the first sealing groove 501 is bonded with a first sealing strip 502, the top of the first sealing strip 502 is bonded with a first sealing gasket 503, and the first sealing gasket 503 is fixed with an extension piece 504 on one side of the inner side of the corresponding connecting frame beam 3, and a concrete layer 505 is filled between the inside of the connecting frame beam 3 and the inside of the oblique groove 703.

[0049] It should be noted that the top of the first sealing gasket 503 abuts against the bottom of the corresponding mulberry board body 1, so that the first sealing gasket 503 can play a role of abutment and sealing, and the extension piece 504 extends to the inside of the corresponding connecting frame beam 3, so that after the extension piece 504 and the solidified concrete layer 505 are connected, the integrity of the overall leak-proof structure can be improved.

[0050] The working principle of the above embodiment is:

[0051] (1) During construction, the support frame 2 and the connecting frame beam 3 are connected and fixed according to the installation construction plan. According to the splicing direction, the mulberry board body 1 is fixed on the top of the connecting frame beam 3, so that the connecting groove 606 moves between the outer sides of the corresponding first semicircular part 603 and the second semicircular part 604, and the front and rear corresponding mulberry board bodies 1 are fitted together, and the first nut 706 is locked so that the first extrusion plate 704 and the second extrusion plate 707 can be pressed downward, so that the opposite sides of the two adjacent mulberry board bodies 1 on the left and right can be squeezed downward, thereby making the first sealing pad 503 and the first sealing strip 502 more stably abutted to improve the tightness of the connection, and the bottom plate 716 is assembled between the opposite sides of the two adjacent connecting frame beams 3, and the extrusion pad 718 and the cylindrical strip 719 are abutted against the bottom of the mulberry board body 1 to complete the sealing connection work at the bottom.

[0052] (2) Apply sealant 710 to the inner side of the docking groove 709, then insert the extrusion block 711 into the inner side of the docking groove 709, and fix the shielding plate 712 between the tops of the two adjacent mulberry board bodies 1. The first seal 713 and the second seal 715 can seal and prevent leakage at the top of the mulberry board body 1. Finally, pour concrete into the interior of the connecting frame beam 3 through the oblique groove 703 and vibrate it so that the concrete can be evenly filled. During the solidification process, the outer side of the mulberry board body 1 will be driven to adapt to the deviation under the action of the adaptation groove 701, and the right side of the second seal 713 and the second seal 715 can be used to seal and prevent leakage. A screw 705 moves inside the movable hole 708, so that the structure can meet the movement requirements when the concrete solidifies. After the concrete is completely solidified, a concrete layer 505 is formed. The concrete layer 505 located inside the connecting frame beam 3 can play an effective connection and sealing role, and the concrete layer 505 located between the inner sides of the corresponding first semicircular member 603 and the second semicircular member 604 can limit the position of the first semicircular member 603 and the second semicircular member 604, thereby increasing the area connected to the main body 1 of the mulberry board, so that the integrity is improved to a certain extent, and the dense joints of the assembled mulberry board have good sealing and leakage prevention capabilities.

[0053] Compared with the prior art, the large-span assembled mulch board close-jointed seam anti-leakage slurry construction device can ensure the basic sealing of the mulch board connection through the coordinated use of the mulch board body 1, the support frame 2, the connecting frame beam 3, the fixing plate 4 and the basic sealing component 500, so that it can meet the demand for anti-leakage slurry use, and under the coordinated action of the connecting component 600, the adjacent mulch boards can be effectively connected after the concrete solidifies, and additional pulling force can be applied to the mulch boards through the coordination of the solidified concrete and the internal structure, thereby improving the integrity of the mulch board connection, and through the use of the sealing reinforcement component 700, the sealing performance of the basic sealing component 500 can be increased while also being able to The joints are sealed in multiple layers through special-shaped sealing structures to prevent liquid from entering, and the structure is arranged to have a certain extension ability, so that matching activities can be carried out when the concrete expands or contracts during the solidification process, avoiding cracking caused by hard extrusion, ensuring the integrity of concrete solidification, and making the solidified concrete have excellent sealing performance, thereby achieving the advantages of greatly improving the sealing and stability of the dense joints of the mulberry board, and solving the problem that the concrete poured by the sealed joint anti-leakage slurry construction device of the assembled mulberry board is easily squeezed with the surrounding structure during the solidification process, resulting in cracking, resulting in insufficient actual sealing and stability.
