Description

Technical Field

[0001] The utility model relates to the technical field of concrete components, in particular to a splicing structure of prefabricated concrete panels. Background Art

[0002] Precast concrete refers to concrete that is made in a factory or on-site (not in the final design location) to make concrete products. Precast concrete is poured elsewhere rather than on the final construction site. Precast concrete of different sizes and shapes can be reinforced with fibers to enhance its reliability and toughness after cracking. Because precast concrete components have been manufactured in the factory, they can significantly speed up the construction of buildings. Adjacent precast concrete components can be spliced ​​to improve the stability of the connection.

[0003] The Chinese utility model patent with announcement number CN209686681U discloses a fastening connection structure of a concrete precast panel, which relates to the field of precast panels and aims to solve the problem of low connection strength of existing concrete precast panels. Its technical points include a precast panel body one and a precast panel body two spliced ​​with the precast panel body one, and also include a plurality of stable tripods arranged in the precast panel body one and extending along the length direction of the precast panel body one, a connecting cavity arranged in the stable tripod and one end of which passes through the precast panel body one, a connecting rod arranged at the connecting end of the precast panel body two and inserted into the connecting cavity, and a fixing component arranged at the connecting ends of the precast panel body one and the precast panel body two, thereby achieving the purpose of improving the connection strength of the concrete precast panel.

[0004] The above-mentioned prior art solutions have the following defects: although the above-mentioned splicing structure can improve the connection strength between the concrete precast panels, the filling channels, filling pipes and other structures as fixed components are exposed on the surface of the precast components, which affects the flatness of the surface of the precast components and will have an adverse effect on the subsequent surface construction of the components. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a splicing structure of concrete precast panels, which can improve the splicing stability between adjacent precast panels, and the splicing structure is not exposed, will not affect the flatness of the surface of the precast components, and will not have an adverse effect on the subsequent component surface construction.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a splicing structure of a concrete precast panel, comprising a panel body, a plug block being fixed at one end of the panel body, a slot being provided at the other end of the panel body, the shape and size of the slot being adapted to the plug block, an inner slot being provided on the surface of the plug block, a fixed block being slidably arranged in the inner slot, the sliding direction of the fixed block being perpendicular to the panel surface of the panel body, a fixed slot being provided on the inner wall of the slot for inserting the fixed block, a plurality of spring sheets being fixed on the side wall of the fixed block, the end of the spring sheet away from the fixed block being inclined and extending toward the direction of the plug block, the end of the spring sheet away from the fixed block being in sliding contact with the inner wall of the fixed slot, and an iron block being fixed on the end of the fixed block away from the plug block.

[0007] Through the above technical solution, personnel splice adjacent plates through plug-in blocks and slots, then take a magnet and place it on the plate surface of the plate, move the magnet to the position of the iron block, the iron block is attracted by the magnet and moves into the fixed slot, the iron block pulls the fixed block into the fixed slot, and after completion, the spring sheet plays the effect of making the fixed block move in one direction to prevent the iron block from falling spontaneously, and the adjacent plates are prevented from separating by plugging the fixed block and the fixed slot. Through this splicing structure, the plate surface does not have any holes or protruding structures, the plate has good flatness, is more beautiful, and will not affect the subsequent surface construction of components.

[0008] Preferably, a groove wall of the inner groove is provided with a receiving groove for the spring piece to enter.

[0009] Through the above technical solution, when the fixing block is completely located in the inner groove, the shrapnel is accommodated by the accommodating groove to prevent the shrapnel from being subjected to force.

[0010] Preferably, the spring pieces are distributed on both sides of the fixing block and are symmetrically arranged.

[0011] Through the above technical solution, the spring pieces symmetrically distributed on both sides have a better effect of restricting the unidirectional movement of the fixed block and the force is more uniform.

[0012] Preferably, a film capsule is fixed at the deepest part of the fixing groove, and glue is contained in the film capsule.

[0013] Through the above technical solution, when a person attracts the iron block to move by a magnet, the iron block moves very fast and has its own inertia, so it can squeeze the film bag to rupture, causing the glue inside to flow out. The glue sticks between the spring sheet below and the wall of the fixed groove, further improving the stability and preventing the iron block and the fixed block from falling spontaneously.

[0014] Preferably, the end of the iron block close to the film capsule is configured as a pointed end.

[0015] Through the above technical solution, the end of the iron block is set as a pointed end, which can ensure that the film capsule can be broken when the iron block squeezes the film capsule.

[0016] Preferably, a plurality of liquid leakage grooves are formed at the end of the spring piece away from the fixing block.

[0017] Through the above technical solution, the leakage groove is used for glue to pass through, that is, the glue on the top spring piece can fall onto the spring piece below through the leakage groove, so that there is glue at the bottom end of each spring piece, thereby improving the fixing effect of all spring pieces and the fixing groove wall.

[0018] Preferably, a limiting block is fixed to the end of the fixing block away from the inserting block, and the inner wall of the fixing groove is provided with a limiting groove which is slidably matched with the limiting block.

[0019] Through the above technical solution, after the fixing block is inserted into the fixing groove, the limiting block is also inserted into the limiting groove. The cooperation between the limiting block and the limiting groove can improve the stability and accuracy of the insertion and avoid left and right shaking between adjacent plates.

[0020] Preferably, the number of the limiting blocks at the end of each of the fixing blocks is two, and the two limiting blocks are respectively located on both sides of the iron block.

[0021] Through the above technical solution, the two symmetrically distributed limit blocks further improve the stability after insertion.

[0022] In summary, the beneficial effects of the present invention compared with the prior art are as follows:

[0023] 1. Through this splicing structure, the splicing of adjacent panels can be completed quickly, and the separation of adjacent panels can be prevented. The panel surface does not have any holes, grooves or protruding structures. The panel has good flatness and is more beautiful, and will not affect the subsequent surface construction of components;

[0024] 2. To prevent separation between plates, just move the magnet, which is easy to operate;

[0025] 3. It can automatically stimulate the glue to bond the internal plug-in structure, with high stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-5 The utility model is described in further detail.

[0033] Reference Figure 1 , which is a splicing structure of a concrete prefabricated panel disclosed in the utility model, comprises a panel body 1, the panel body 1 is made of concrete, and a plurality of panel bodies 1 are connected left and right for splicing. An insert block 2 is fixed at one end of the panel body 1, and a slot 3 is provided at the other end of the panel body 1. The shape and size of the slot 3 are adapted to the insert block 2. The number of the insert blocks 2 and the slot 3 is set to be several. When the insert block 2 of one panel body 1 is inserted into the slot 3 of another panel body 1, the preliminary positioning of the adjacent panel bodies 1 is completed.

[0034] Reference Figure 2 and Figure 3 An inner groove 21 is provided on the surface of the insert block 2, and a fixing block 4 is slidably arranged in the inner groove 21. The sliding direction of the fixing block 4 is perpendicular to the board surface of the board body 1. A fixing groove 31 is provided on the inner wall of the slot 3 for the fixing block 4 to be inserted. When the fixing block 4 is inserted into the fixing groove 31, the separation of the adjacent board bodies 1 can be limited.

[0035] A plurality of spring pieces 41 are fixed to the side wall of the fixed block 4. The ends of the spring pieces 41 away from the fixed block 4 extend obliquely toward the insert block 2. The ends of the spring pieces 41 away from the fixed block 4 are in sliding contact with the inner wall of the fixed groove 31. The spring pieces 41 are distributed on both sides of the fixed block 4 and are symmetrically arranged. The groove wall of the inner groove 21 is provided with a receiving groove 22 for the spring pieces 41 to enter. The groove width of the receiving groove 22 is greater than the groove width of the fixed groove 31. When the fixed block 4 slides into the inner groove 21, the spring pieces 41 do not contact the groove wall of the receiving groove 22.

[0036] By setting the spring sheet 41, when the fixed block 4 slides into the fixed groove 31, the spring sheet 41 also enters the fixed groove 31. As the spring sheet 41 slides and contacts the groove wall of the fixed groove 31, since the spring sheet 41 is set obliquely, the elastic force of the spring sheet 41 expanding outward also acts on the groove wall of the fixed groove 31, thereby producing a one-way movement effect. Specifically, when the fixed block 4 slides into the fixed groove 31, the resistance of the spring sheet 41 acting on the groove wall of the fixed groove 31 is small, thereby facilitating the sliding of the fixed block 4 into the fixed groove 31; when the fixed block 4 slides out of the fixed groove 31, the resistance of the spring sheet 41 acting on the groove wall of the fixed groove 31 is large, thereby preventing the fixed block 4 from sliding out of the fixed groove 31, thereby achieving the effect of the fixed block 4 entering the fixed groove 31 in one direction.

[0037] An iron block 42 is fixed to the end of the fixed block 4 away from the plug block 2. The iron block 42 is used to cooperate with the magnet outside the plate body 1, and the iron block 42 is attracted to move by the magnet. A film capsule 32 is fixed to the deepest part of the fixed groove 31, and glue 33 is contained in the film capsule 32. The end of the iron block 42 close to the film capsule 32 is set as a tip, and this structure facilitates the iron block 42 to pierce the film capsule 32. When the tip of the iron block 42 squeezes and pierces the film capsule 32, the glue 33 leaks out of the film capsule 32 and flows to the spring 41 below, and then the glue 33 flows along the spring 41 to the groove wall of the fixed groove 31. After the glue 33 solidifies, it produces a fixing effect between the spring 41 and the groove wall of the fixed groove 31, further preventing the spring 41 and the fixed block 4 from spontaneous movement.

[0038] A plurality of leakage grooves 411 are provided at the end of the spring piece 41 away from the fixed block 4, and the leakage grooves 411 are used for the glue 33 to pass through, that is, the glue 33 on the top spring piece 41 can fall onto the spring piece 41 below through the leakage grooves 411, so that there is glue 33 at the bottom end of each spring piece 41, thereby improving the fixing effect of all spring pieces 41 and the groove wall of the fixed groove 31.

[0039] Reference Figure 2 and Figure 4 A limiting block 43 is also fixed to the end of the fixed block 4 away from the plug-in block 2, and a limiting groove 34 is provided on the inner wall of the fixed groove 31 to slide with the limiting block 43. There are two limiting blocks 43 at the end of each fixed block 4, and the two limiting blocks 43 are respectively located on both sides of the iron block 42. When the fixed block 4 is inserted into the fixed groove 31, the limiting block 43 is also inserted into the limiting groove 34. The cooperation between the limiting block 43 and the limiting groove 34 can improve the stability and accuracy of the plug-in connection and prevent the adjacent plate bodies 1 from shaking left and right.

[0040] It should be noted that after the fixing block 4 moves to the bottom of the inner groove 21 , the iron block 42 and the limiting block 43 do not protrude from the surface of the plug-in block 2 , and the iron block 42 and the limiting block 43 will not hinder the plug-in process of the plug-in block 2 and the slot 3 .

[0041] Reference Figure 1 , Figure 5 and Figure 3 The implementation principle of the splicing structure of the concrete precast panel is as follows: the personnel splice the adjacent panels 1 through the insert block 2 and the slot 3, then take the magnet and place it on the panel surface of the panel 1, move the magnet to the position of the iron block 42, the iron block 42 is attracted by the magnet and moves into the fixed slot 31, the iron block 42 pulls the fixed block 4 to insert into the fixed slot 31, and after completion, the spring piece 41 plays the role of making the fixed block 4 move in one direction, preventing the iron block 42 from falling spontaneously. And because the iron block 42 moves very fast and has its own inertia, the tip of the iron block 42 can squeeze the film capsule 32 to break, so that the glue 33 inside flows out, and the glue 33 sticks between the spring piece 41 below and the wall of the fixed slot 31, further improving the stability and preventing the iron block 42 and the fixed block 4 from falling spontaneously.

[0042] Through this splicing structure, the adjacent plates 1 can be quickly spliced ​​and can prevent the adjacent plates 1 from separating. The magnets can be moved during operation, which is very easy to operate. The glue 33 can be automatically activated to bond the internal plug-in structure, which is highly stable. The plate surface of the plate 1 does not have any holes or protruding structures, so the plate 1 has good flatness and is more beautiful, and will not affect the subsequent surface construction of components.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
