Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete pouring, in particular to a pouring formwork and a pouring system. BACKGROUND

[0002] In highway construction, concrete wall pouring is a core process. In highway engineering, concrete retaining walls, crash barriers, bridge piers and other wall structures bear the key role of resisting lateral soil pressure, ensuring road alignment stability and buffering vehicle impact. The construction quality directly determines the stability and long-term performance of the overall structure. In this process, the fixing method and support system of the formwork play a decisive role. Only by ensuring that the formwork has reliable fixing effect and efficient support capacity can the quality of the concrete wall be guaranteed, and the wall can truly shoulder the responsibility of supporting the building structure and ensuring its stability and durability.

[0003] A concrete wall pouring plate fixing structure is disclosed in Chinese Patent No. CN222991171U, which includes a tensioning screw rod, and a formwork stopper, a reinforcing bar pressing element and a locking nut are sequentially arranged from the inside to the outside at both ends of the tensioning screw rod. The formwork stopper and the reinforcing bar pressing element at the same end of the tensioning screw rod are located on the inside and outside of the formwork, respectively, and the outside wall of the formwork stopper abuts against the inside wall of the formwork, and the inside wall of the reinforcing bar pressing element abuts against the outside wall of the formwork. The advantages are that the pouring plate has sufficient strength when pouring the concrete wall, and the formwork deformation is effectively prevented. Although the above-mentioned patent can prevent the formwork from deforming, it cannot prevent the poured concrete from being waterproofed.

[0004] A water-stopping three-section tensioning screw rod is disclosed in Chinese Patent No. CN212317504U, which includes a screw rod body and a water-stopping part. The water-stopping part is arranged on the screw rod body, and is used to prevent water flow from moving along the axial direction of the screw rod body. Since the water-stopping part is arranged on the screw rod body, it can prevent water flow from moving along the axial direction of the screw rod body, has a good blocking effect on the penetration of water flow along the screw rod body in the concrete wall, improves the water-blocking performance of the tensioning screw rod, and has important significance for reducing the water penetration damage to the wall.

[0005] Although the above-mentioned patent can achieve water-blocking, due to long-term use and drying, gaps may be left between the water-stopping part and the concrete, which can still cause some water to flow from the gaps between the water-stopping part and the concrete. At the same time, the middle part of the above-mentioned three-section tensioning screw rod will be left inside, resulting in an increase in economic investment cost.

[0053] The reinforcing assembly 3 penetrates through both sides of the pouring plate 1, and is used for reinforcing both sides of the pouring plate 1 to prevent the mold from expanding.

[0054] Further, the reinforcing assembly 3 comprises a water stop part 31 for preventing water from flowing along the length direction of the reinforcing assembly 3; the water stop part 31 can block the flow of water through the gap between the reinforcing assembly 3 and the poured concrete, and is suitable for pouring scenes with waterproof requirements.

[0059] The butt joint screw hole 36 is arranged at one end of the other screw rod 32 close to the water stop part 31, can directly cooperate with the butt joint screw column 35, and realizes switching of the reinforcing assembly 3 from the state of being provided with the water stop part 31 to the state of being not provided with the water stop part 31; in the present application, when the water stop part 31 is not needed, the water stop part 31 is taken down, the butt joint screw column 35 is screwed into the butt joint screw hole 36, direct connection of the two screw rods is realized, the state switching is quickly completed, and the concrete pouring construction requirement without the water stop part 31 can be met.

[0060] The first limiting pressing plate 37 is sleeved on the end part of the screw rod 32; in the present application, the first limiting pressing plate 37 can transmit the pressure of the first pressing nut 38 to the formwork through the horizontal reinforcing steel pipe 39, and prevents the formwork from being damaged due to excessive local pressure.

[0061] A first compression nut 38 is threadedly connected to the end of the screw rod 32; in particular, the first compression nut 38 can be a hexagonal nut matched with the thread of the screw rod 32, and by screwing the first compression nut 38, pressure can be generated on the first limiting pressing plate 37, and then the horizontal reinforcing steel pipe 39 is tightly attached to the formwork, so as to realize reinforcement, and the material thereof is high-strength steel, which can ensure sufficient locking force.

[0062] The water stop part 31 comprises a butt joint pipe 3101, the inner wall of which is provided with threads at both ends, and the peripheral wall of which is threadedly connected with limiting plates 3102 at both ends, and the peripheral wall of the middle part is provided with a through sliding groove 3103; in particular, the threads at both ends of the inner wall of the butt joint pipe 3101 are matched with the screw rod 32, so as to be conveniently connected, and the limiting plates 3102 are circular, and are threadedly connected at both ends of the butt joint pipe 3101, so as to limit the moving range of the water stop plates 3104.

[0063] Two water stop plates 3104 are symmetrically arranged on the peripheral wall of the butt joint pipe 3101; in particular, the water stop plates 3104 are made of steel plates, and a hole matched with the outer diameter of the butt joint pipe 3101 is arranged at the center, and the water stop plates 3104 can move along the axial direction after being arranged on the peripheral wall of the butt joint pipe 3101.

[0064] Two pressing members 3105 are symmetrically arranged in the through sliding groove 3103 and are integrally welded with the water stop plates 3104; when the butt joint stud 35 extrudes the pressing members 3105, the pressing members 3105 move to drive the water stop plates 3104 to move and extrude the high-elastic rubber blocks 3106, so as to realize pre-compression of the water stop part 31. The high-elastic rubber blocks 3106 are arranged between the two pressing members 3105; when being extruded by the pressing members 3105, the high-elastic rubber blocks 3106 are elastically deformed, and under the elastic force of the high-elastic rubber blocks 3106, the water stop plates 3104 are pushed to move outward after the screw rod 32 is removed, so as to enhance the water stop effect.

[0065] The high-elastic rubber sleeve 3107 is arranged on the two water stop plates 3104 at both ends and has an arc-shaped concave part 3108 at the middle part. Before pouring, the water stop part 31 is pre-compressed, and the arc-shaped concave part 3108 at the middle part is more concave in the pre-compressed state of the water stop part 31; after pouring, under the elastic force of the high-elastic rubber blocks 3106, the water stop plates 3104 are pushed to move outward after the screw rod 32 is removed, and the high-elastic rubber sleeve 3107 is stretched, so that the arc-shaped concave part 3108 is more tightly attached to the poured concrete, and the waterproof property is further enhanced.

[0066] The butt joint pipe 3101 is provided with a first groove 3109 matched with the first outer sleeve 34 at both ends. By arranging the first groove 3109, when the first outer sleeve 34 is matched with the butt joint pipe 3101, the end of the first outer sleeve 34 can be embedded in the first groove 3109, so as to realize the tight connection of the two, and prevent the concrete from entering the gap.

[0067] The pouring plate 1 comprises a formwork body 101, the back of which is provided with a "U"-shaped reinforcing rib boss 102 integrally poured with the formwork body 101, and the middle area of the back is provided with reinforcing ribs 103 which are longitudinally and transversely intersected and integrally poured with the formwork body 101. The height of the "U"-shaped reinforcing rib boss 102 is 5-10 cm, which is integrally poured with the formwork body 101 to enhance the strength of the periphery of the formwork and prevent the deformation of the corners. The reinforcing ribs 103 in the middle area of the back are longitudinally and transversely intersected to form a grid structure, further improving the overall bearing capacity of the formwork. A pull hole 104 is formed in the middle of the formwork body 101 for the screw rod 32 to pass through.

[0068] A plurality of matching holes 105 are formed on the "U"-shaped reinforcing rib boss 102, which cooperate with the fixing assembly 2 to realize the fixing between adjacent pouring plates 1. Specifically, the number of the matching holes 105 is determined according to the length of the "U"-shaped reinforcing rib boss 102, and generally one is formed every 30-50 cm. The hole diameter is matched with the fixing tube 201 of the fixing assembly 2, and the adjacent formworks can be firmly connected by inserting the fixing assembly 2 into the matching hole 105, so as to ensure the flatness and stability of the spliced part of the formwork.

[0069] The fixing assembly 2 comprises a fixing tube 201, the bottom side wall of which is symmetrically provided with two limiting protrusions 202, and the top thereof is provided with an inclined handle part 203. In the present application, the limiting protrusions 202 are integrally formed with the bottom of the fixing tube 201, which can prevent the fixing tube 201 from sliding out of the matching hole 105, and the inclined handle part 203 is integrally formed with the fixing tube 201, which is convenient for the operator to hold and plug the fixing assembly 2.

[0070] The conical limiting sleeve 33 comprises a conical body 3301, one end of which is provided with a second groove 3302 matched with the first outer sleeve 34. Specifically, when the first outer sleeve 34 cooperates with the conical limiting sleeve 33, the end of the first outer sleeve 34 can be embedded in the second groove 3302, so that the two are more closely connected, and the concrete is prevented from entering.

[0071] It also comprises a second outer sleeve 312 which can butt joint the two first outer sleeves 34. Preferably, the second outer sleeve 312 is made of a PVC pipe, the outer diameter of which is the same as the inner diameter of the flared part 3401, and the length thereof is determined according to the gap between the two first outer sleeves 34. When it is necessary to lengthen the outer sleeve or connect the two first outer sleeves 34, the second outer sleeve 312 is sleeved on the butt joint of the two first outer sleeves 34, which can play a protective and connecting role, so that the first outer sleeve 34 and the second outer sleeve 312 form an integral whole. The first outer sleeve 34 is provided with a flared part 3401 at one end close to the water stop part 31. Specifically, the flared part 3401 is a flared structure formed by flaring the end of the first outer sleeve 34, which facilitates the butt joint of the first outer sleeve 34 and the second outer sleeve 312.

[0072] The present application also discloses a pouring system, the pouring system of the present application adopts the formwork described above, and further comprises a horizontal reinforcing steel pipe 39 arranged between the first limiting pressing plate 37 and the pouring plate 1 and used for reinforcing the formwork in the horizontal direction. Specifically, the horizontal reinforcing steel pipe 39 is arranged in cooperation with the first limiting pressing plate 37 and the formwork to form a support in the horizontal direction, thereby dispersing the horizontal force received by the formwork and preventing the formwork from deforming in the horizontal direction.

[0073] Further, a second limiting pressing plate 310 is sleeved on the end of the screw rod 32 and located outside the first pressing nut 38.

[0074] A second pressing nut 313 is threadedly connected to the end of the screw rod 32.

[0075] A vertical reinforcing steel pipe 311 is arranged between the horizontal reinforcing steel pipe 39 and the first limiting pressing plate 37 and used for reinforcing the formwork in the vertical direction. Specifically, the vertical reinforcing steel pipe 311 is made of the same material as the horizontal reinforcing steel pipe 39 and arranged along the height direction of the formwork and between the horizontal reinforcing steel pipe 39 and the first limiting pressing plate 37. The vertical reinforcing steel pipe 311 can effectively resist the pressure of the concrete on the formwork in the vertical direction through the pressing of the second pressing nut 313, thereby preventing the formwork from vertically rising.

[0076] In use, first, the water stop part 31 is butted against the two screw rods 32, wherein the screw rod 32 without the butt joint stud 35 is tightened to just abut against the pressing part 3105, and the screw rod 32 with the butt joint stud 35 is tightened to first abut against the pressing part 3105 and then continue to be screwed to extrude the high-elastic rubber block 3106 and simultaneously drive the water stop plate 3104 to move to the other water stop plate 3104. The movement of the water stop plate 3104 drives the high-elastic rubber sleeve 3107 to move. Due to the arrangement of the arc-shaped concave part 3108, the arc-shaped concave part 3108 is more concave inwardly. Finally, the screw rod 32 with the butt joint stud 35 is tightened with the butt joint pipe 3101. Then, the first outer sleeve 34 is penetrated on the screw rod 32. Then, the tapered limiting sleeve 33 is butted against the screw rod 32, thereby completing the pre-assembly of the reinforcing assembly 3.

[0077] Then, one side of the formwork is placed, the assembled reinforcing assembly 3 is penetrated into the opposite pulling hole 104 of the placed formwork, the opposite pulling hole 104 of the other side of the formwork is penetrated through the reinforcing assembly 3, then the first limiting pressing plate 37 and the first pressing nut 38 are butted against the screw rod 32, and then the first pressing nut 38 is fastened according to requirements.

[0078] The present application can insert the horizontal reinforcing steel pipe 39 between the formwork and the first limiting pressing plate 37 according to requirements, thereby enhancing the support in the horizontal direction, dispersing the horizontal force received by the formwork, and preventing the formwork from deforming in the horizontal direction.

[0079] The present application can also place a vertical reinforcing steel pipe 311 outside the horizontal reinforcing steel pipe 39 according to the needs, and then press the vertical reinforcing steel pipe 311 on the horizontal reinforcing steel pipe 39 through the second limiting pressing plate 310 and the second pressing nut 313, thereby enhancing the support in the vertical direction, dispersing the horizontal force received by the formwork, and preventing the formwork from deforming in the vertical direction.

[0080] After the concrete pouring is completed, the second pressing nut 313, the second limiting pressing plate 310, the first limiting pressing plate 37, and the first pressing nut 38 are removed first, and then the horizontal reinforcing steel pipe 39 and the vertical reinforcing steel pipe 311 are removed. Then, the screw rod 32 on the same formwork is loosened multiple times by using an electric sleeve head and a hand drill, and each time a few turns are loosened. After the screw rod 32 is loosened, it moves outward and pushes the formwork outward by driving the conical limiting sleeve 33. After multiple loosening, on the one hand, the screw rod 32 is completely separated from the butt joint pipe 3101, and on the other hand, the formwork is pushed to achieve demolding. Since the screw rod 32 is provided with the first outer sleeve 34, after the screw rod 32 is separated from the butt joint pipe 3101, the screw rod 32 can be completely pulled out of the first outer sleeve 34, thereby improving the reusability and avoiding the problem of low reusability caused by leaving most of the reinforcing assembly 3 in the wall as in the prior art.

[0081] After the screw rod 32 is separated from the butt joint pipe 3101, since the high-elasticity rubber block 3106 is in a compressed state before pouring, after the screw rod 32 is removed, the high-elasticity rubber block 3106 will push the two water stop plates 3104 to move to both sides under the elastic force of the high-elasticity rubber block 3106, thereby compressing the high-elasticity rubber sleeve 3107 on the poured concrete. Not only does this achieve the effect of enhancing water stop, but it also achieves a two-stage sealing effect, avoiding the situation where a gap is left between the water stop piece and the concrete due to concrete solidification shrinkage, as in the prior art, which prevents water stop from being achieved.

[0082] As shown in Figure 9 When the water stop part 31 is not needed at the partial pouring position, the butt joint stud 35 and the butt joint hole 36 of the two screw rods 32 are directly butt jointed, then the second outer sleeve 312 is sleeved on the screw rod 32, then the first outer sleeve 34 is butt jointed with the second outer sleeve 312, and then the conical limiting sleeve 33 is butt jointed with the screw rod 32, thereby completing the pre-assembly of the reinforcing assembly 3 without the water stop part 31, and then used for concrete pouring without the water stop part 31. The present application can switch the reinforcing assembly 3 with the water stop part 31 to the reinforcing assembly 3 without the water stop part 31, thereby being applicable to concrete pouring with water stop and concrete pouring without water stop.

[0083] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that the technical solutions described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalent features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
