Description

Technical Field

[0001] The invention relates to the technical field of building formwork, and in particular to a disassembly-free wall formwork and an assembly method thereof. Background Art

[0002] In building construction, wall formwork is a common construction tool used to construct the basic framework of the wall. However, due to the lack of sufficient versatility and adjustability in design, traditional wall formwork is difficult to adapt to building structures of different sizes and shapes, which increases the complexity and difficulty of the installation process. In addition, in the installation process of traditional wall formwork, in order to ensure the stability of the formwork, complex fastening measures are usually required, such as the use of a large number of bolts, nuts and other connectors, which not only increases the installation workload, but may also lead to longer installation time. In addition, a large number of connectors are used for fixing, and these connectors may require special tools or methods when disassembling, which increases the difficulty of disassembly.

[0003] In view of the problems of traditional wall formwork, engineers have developed a spliced ​​non-disassembly wall formwork structure (CN118564042A) to solve the problem. The solution is to produce the formwork body through plastic molds, with a unique convex and concave groove design and H-shaped connectors, to achieve fast and stable wall construction without removing the formwork, greatly reducing construction costs and improving construction efficiency. However, engineers found in actual use that the above technical solution still has aspects that need to be optimized:

[0004] 1. The convex-concave design is used to seal the template joints, which requires forming a convex-concave structure on the prefabricated template. In order to ensure smooth joints, the precision of the convex-concave structure is required to be high, which greatly increases the difficulty of template production and reduces production efficiency.

[0005] 2. When using H-type connectors to connect the formwork on both sides, the force-bearing area of ​​the traction end of the H-type connector is relatively low, which can easily cause the formwork on both sides to be subjected to lateral pressure from the concrete when pouring concrete, resulting in stress concentration at the H-type connector, making the corresponding formwork easily break, resulting in reduced connection strength.

[0006] Therefore, it is of great practical significance to develop a wall formwork and an assembly method thereof which is easy to produce, simple to install and disassemble, and has strong connectivity. Summary of the invention

[0007] The purpose of the present invention is to provide a non-disassembly wall formwork and an assembly method thereof, which solves the problem that the convex and concave groove design of the formwork body increases the difficulty of formwork production and reduces production efficiency by improving the formwork body structure.

By using traction plates on both sides of the connecting piece, the contact area with the formwork body is increased, thereby solving the problem that the force-bearing area of ​​the traction end of the ordinary H-type connecting piece is relatively low, which easily leads to stress concentration at the H-type connecting piece, making the corresponding formwork easily break and resulting in reduced connection strength.

DETAILED DESCRIPTION

[0067] 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.

[0068] Embodiment 1

[0069] like Figure 1-Figure 9As shown, this embodiment provides a wall formwork that does not require disassembly, and the wall formwork that does not require disassembly includes two sets of template bodies 10 arranged in parallel and spaced apart. The template body 10 can be a concrete slab prefabricated by a mold, or a tile structure of the same size, so that the wall surface is free from decoration and is more practical. The specific size is set according to actual needs. This embodiment does not limit the material of the template body 10, and it can be concrete, tile, etc.

[0070] The template body 10 includes two groups of long sides and two groups of short sides. The two groups of long sides and the two groups of short sides form a quadrilateral, and it should be understood that the two groups of long sides can also be equal to the short sides to form a square template.

[0071] The same template body 10 is provided with at least one set of assembly grooves 40 on the two sets of long sides, and the positions of the assembly grooves 40 on the two sets of long sides of the same template body 10 are correspondingly arranged (such as Figure 1 As shown, the assembly grooves 40 on the two sets of long sides of the same template body 10 are arranged in corresponding positions up and down).

[0072] The present application does not limit the forming method of the assembly groove 40 , for example, a T-shaped slotted piece may be used for processing.

[0073] Furthermore, the two sets of template bodies 10 can be arranged symmetrically (eg Figure 1 As shown), the assembly grooves 40 on the same side of the two sets of template bodies 10 are arranged one by one; when the same template body 10 is provided with at least two sets of assembly grooves 40 on the two sets of long sides, the two sets of template bodies 10 can also be arranged in a staggered manner (such as Fig. 9 As shown), and the two sets of template bodies 10 are offset by at least one interval between adjacent assembly grooves 40;

[0074] The two corresponding groups of assembly grooves 40 are cooperatively connected with connecting members 20 , wherein the connecting members 20 are used to connect the two groups of formwork bodies 10 together, and provide traction to the formwork bodies 10 on both sides when pouring concrete.

[0075] Furthermore, the number of the above-mentioned connecting members 20 is consistent with the number of the assembly grooves 40 opened on the long sides of each group of template bodies 10. In this embodiment, four groups of assembly grooves 40 are opened on the long sides of each group of template bodies 10 as an example (eg Figure 2 shown).

[0076] The distance between the central axes of two adjacent groups of assembly grooves 40 is equal to the sum of the distances from the two outermost groups of assembly grooves 40 to the corresponding short sides on the same side.

[0077] Furthermore, the four groups of assembly grooves 40 may be distributed symmetrically or asymmetrically about the vertical center line of the template body 10 .

[0078] When the two sets of template bodies 10 are arranged symmetrically and the assembly grooves 40 on the template bodies 10 are distributed symmetrically about the vertical center line of the template bodies 10 (such as Figure 1 As shown), the connecting pieces 20 on the corresponding two groups of formwork bodies 10 are symmetrically distributed, so that the force of the limiting connections at both ends of the formwork bodies 10 is more even, ensuring that the force of the two groups of formwork bodies 10 is stable when the concrete slurry is injected; at the same time, the subsequent multiple groups of formwork bodies 10 are horizontally spliced ​​to ensure that the spacing between adjacent connecting pieces 20 after splicing is consistent, so that the concrete side pressure at both ends of the splicing of the horizontally spliced ​​formwork bodies 10 is consistent, ensuring the stability of the dismantling-free wall formwork system formed by the splicing combination.

[0079] When the two sets of template bodies 10 are arranged in a staggered manner and the assembly grooves 40 on the template bodies 10 are symmetrically distributed about the vertical center line of the template bodies 10 (such as Fig. 9 As shown), the connecting members 20 can be staggered (that is, the end connecting members 20 of the current two groups can be connected to the assembly grooves 40 of another group that are transversely staggered and corresponding thereto), so that when multiple groups of template bodies 10 are transversely spliced, the mutual clamping connection is more firmly provided to the multiple groups of template bodies 10 after splicing. A stable connection force is provided to the whole.

[0080] Furthermore, if Figure 6 As shown, the above-mentioned connecting member 20 is H-shaped, and the connecting member 20 includes a connecting rod 21 in the middle and a traction plate 22 connected to both ends of the connecting rod 21. The two traction plates 22 are fixed to the connecting rod 21 by welding. A plurality of connecting members 20 are correspondingly assembled in the assembly grooves 40, so that the formwork bodies 10 on both sides are sufficiently limited, ensuring that when pouring concrete, the pouring cavity formed between the two formwork bodies 10 can stably support and limit the concrete inside.

[0081] The traction disk 22 may be circular or polygonal.

[0082] In addition, the above-mentioned connecting member 20 increases the effective contact area with the template body 10 by using traction discs 22 on both sides. When pouring concrete, when the template bodies 10 on both sides are subjected to lateral pressure from concrete, due to the large effective contact area between the traction discs 22 and the template body 10, the stress of the limiting traction is dispersed on the contact surface between the traction discs 22 and the template body 10, avoiding stress concentration. Therefore, the corresponding connection of the template is not easy to break, thereby enhancing the connection strength.

[0083] Furthermore, since the traction disk 22 has a larger area, under the condition of the same tensile strength, the thickness of the traction disk 22 can be thinner than that of the rod-shaped structure, thereby making it more convenient to process the template body 10 when processing the matching assembly groove 40, and the long side processing range of the template body 10 is also more sufficient.

[0084] Furthermore, if Figure 1-Figure 4 As shown, the template body 10 of this embodiment cancels the setting of the concave-convex connection structure, and seals the two sets of spliced ​​template bodies 10 by setting a sealing strip 30, wherein the sealing strip 30 includes a set of long sides and a set of short sides, and the two are connected to each other, the long side of the sealing strip 30 corresponds to the long side of the template body 10, the short side of the sealing strip 30 corresponds to the short side of the template body 10, and as shown in FIG. Figure 7 As shown, the sealing strip 30 is also provided with matching grooves 50 , the number of which is consistent with the number of the assembly grooves 40 , and the distances between the matching grooves 50 are set according to the positions of the assembly grooves 40 , and the matching grooves 50 are adapted to the connector 20 to facilitate subsequent installation.

[0085] It should be noted that the thickness of the sealing strip 30 on the short side should not be too thick to avoid affecting the uniformity of the traction force of the template body 10 after transverse splicing (if it is too thick, the distance between the two assembly grooves 40 will be changed, which exceeds the allowable error range); and the use of the sealing strip 30 can resolve the thermal expansion and contraction problems at the joints of the template body 10, and prevent leakage of concrete when pouring concrete. The sealing strip 30 can be made of a variety of materials, and its width is similar to the width of the long side of the template body 10.

[0086] Embodiment 2

[0087] like Figure 5 As shown, this embodiment further refines the assembly groove 40 in the first embodiment, wherein the assembly groove 40 includes a semicircular through groove 41 and a semicircular force-bearing groove 42, wherein the force-bearing groove 42 is adapted to the traction disc 22 in the thickness direction, so as to facilitate the longitudinal position limitation of the traction disc 22, wherein the through groove 41 and the force-bearing groove 42 can also be long semicircular, and during processing, a semicircular cutting piece is used to move along the long side direction for processing;

[0088] The longitudinal edge of the through groove 41 and the edge of the connection between the through groove 41 and the force groove 42 are rounded to facilitate matching the welding structure left at the connection between the connecting rod 21 and the traction plate 22.

[0089] Embodiment 3

[0090] This embodiment is a further refinement of the sealing strip 30 in the first embodiment.

[0091] like Figure 7 and Figure 8 As shown, the matching groove 50 includes an air avoidance groove 1 51 and an air avoidance groove 2 52, and the air avoidance groove 1 51 and the air avoidance groove 2 52 are arranged vertically to each other, wherein the air avoidance groove 1 51 cooperates with the connecting rod 21, and the air avoidance groove 2 52 cooperates with the traction plate 22, so as to facilitate installation on the template body 10 with the connecting part 20, while ensuring the sealing of the connection.

[0092] And if Figure 8As shown, a T-shaped sealing structure is provided on the side of the sealing strip 30 near the air avoidance groove 51, which can prevent leakage of slurry at the joints of multiple sets of template bodies 10, and the head connection setting of the air avoidance groove 51 makes it easier to form the sealing strip 30 during the production and processing, avoiding bending and deformation at each matching groove 50.

[0093] Furthermore, if Fig. 20 and Fig.21 As shown, the sealing strip 30 is smoothly arranged near the side of the air avoidance groove 51. Compared with the above-mentioned solution of setting a T-shaped sealing structure, the smoothly arranged sealing strip 30 is easier to produce and saves costs.

[0094] Embodiment 4

[0095] like Fig.10 and Fig.11 As shown, on the basis of Example 2 or Example 3, a steel mesh is arranged inside the template body 10 in this embodiment, and the steel mesh includes longitudinal steel bars 60 distributed along the long side of the template body 10 and transverse steel bars 70 distributed along the short side of the template body 10, wherein the longitudinal steel bars 60 and the transverse steel bars 70 are staggered in the thickness direction of the template body 10 to avoid mutual interference between the two, and the tensile and compressive strengths of the template body 10 are improved by the longitudinal steel bars 60 and the transverse steel bars 70, so that when the connecting piece 20 pulls the template bodies 10 on both sides, the stress-bearing part (i.e., the connection between the template body 10 and the connecting piece 20) maintains a certain strength to avoid the template body 10 from collapsing due to the stress.

[0096] Furthermore, the steel mesh is located at the most stressed position inside the template body 10. Due to the supporting effect of the support member 80, the height uniformity of the steel mesh inside the template body 10 is ensured, and cutting of the steel mesh is avoided when processing the assembly groove 40.

[0097] And further, if Fig.11 and Fig.12 As shown, a longitudinal steel bar 60 is symmetrically arranged on both sides of the groove 41 of the assembly groove 40, and a transverse steel bar 70 is arranged at the bottom of the groove 41, and the maximum axial plane spacing of the longitudinal steel bars 60 on both sides is greater than the distance of the force groove 42 along the long side direction of the template body 10, and the bottom of the axial plane of the transverse steel bar 70 along the short side direction of the template body 10 is higher than the bottom surface of the force groove 42, ensuring that when the force groove 42 is subjected to force, the two longitudinal steel bars 60 and the one transverse steel bar 70 can further provide support force to ensure the strength of the force-bearing part.

[0098] Embodiment 5

[0099] like Fig.12As shown, in this embodiment, on the basis of the fourth embodiment, a support member 80 is further provided at the intersection of the longitudinal reinforcement 60 and the transverse reinforcement 70, and the support member 80 may be a first support member 81, a second support member 82, or a third support member 83;

[0100] Among them Fig.13 and Fig.14 As shown, the first support member 81 includes a first supporting member 812, at least one first leg 811 is provided at the bottom of the first supporting member 812, and a first supporting groove 813 is provided inside the first supporting member 812, wherein the opening of the first supporting groove 813 faces upward, and the first supporting groove 813 is an arc shape or a U shape larger than a semicircle, and the longitudinal steel bar 60 or the transverse steel bar 70 supported inside is fully limited by the design larger than a semicircle (when it is an arc shape, since it is larger than a semicircle, the arc in the area above the semicircle will limit the longitudinal steel bar 60 or the transverse steel bar 70 supported inside up and down);

[0101] Furthermore, if Fig.13 As shown, support wings 814 are symmetrically arranged on both radial sides of the first supporting member 812, and the support wings 814 on both sides are connected to the outer axial surface of the first supporting member 812, and a support opening 815 is arranged through the opening of the first supporting groove 813. The cross-arranged longitudinal steel bars 60 and the transverse steel bars 70 are stably supported by the support wings 814 on both sides, the support opening 815 and the first supporting member 812, so as to avoid the bending of the longitudinal steel bars 60 and the transverse steel bars 70 under the force of the template body 10 during pouring, and because the support wings 814 on both sides are connected and supported by the longitudinal steel bars 60 or the transverse steel bars 70, the force on the first supporting member 81 during pouring will not deflect around the center of the first supporting groove 813, thereby causing the support ends on both sides of the longitudinal steel bars 60 or the transverse steel bars 70 to be unbalanced, affecting the support effect.

[0102] Furthermore, if Fig.14 As shown, when the first supporting groove 813 is an arc shape larger than a semicircle, the top of the circular trajectory surrounded by the arc surface in the first supporting groove 813 is tangent to the top surfaces of the supporting wings 814 on both sides, so that the longitudinal steel bars 60 or transverse steel bars 70 supported in the first supporting groove 813 are tangent to the transverse steel bars 70 or longitudinal steel bars 60 supported by the supporting wings 814 on both sides. When the first supporting groove 813 is U-shaped, the longitudinal steel bars 60 or transverse steel bars 70 supported in the first supporting groove 813 are also tangent to the transverse steel bars 70 or longitudinal steel bars 60 supported by the supporting wings 814 on both sides, thereby ensuring the connection between the longitudinal steel bars 60 and the transverse steel bars 70 during pouring, and working together to provide more sufficient supporting force.

[0103] Among them Fig.15 and Fig.16As shown, the second support member 82 includes a second supporting member 822, at least one second leg 821 is provided at the bottom of the second supporting member 822, and a second supporting groove 823 is provided inside the second supporting member 822, wherein the opening of the second supporting groove 823 faces upward, and the second supporting groove 823 is an arc shape or a U shape larger than a semicircle, and the longitudinal steel bar 60 or the transverse steel bar 70 supported inside is fully limited by the design larger than a semicircle (when it is an arc shape, since it is larger than a semicircle, the arc in the area above the semicircle will limit the longitudinal steel bar 60 or the transverse steel bar 70 supported inside up and down);

[0104] Furthermore, if Fig.15 As shown, a third supporting member 824 is provided on one radial side of the second supporting member 822, the third supporting member 824 is connected to the outer axial surface of the second supporting member 822, and a third supporting groove 825 is provided inside the third supporting member 824, the third supporting groove 825 is consistent with the second supporting groove 823, and is also an arc shape or a U shape larger than a semicircle, wherein the third supporting groove 825 is provided through the opening of the second supporting groove 823, and a supporting portion 826 is provided on the other side of the opening of the second supporting groove 823, 6 and the second supporting member 822 cooperate to stably support the cross-arranged longitudinal reinforcement 60 and transverse reinforcement 70 to prevent the longitudinal reinforcement 60 and transverse reinforcement 70 from bending when the template body 10 is poured. In addition, since the third supporting member 824 is provided on one side to connect and support the longitudinal reinforcement 60 or the transverse reinforcement 70, the second supporting member 82 will not deflect around the center of the second supporting groove 823 when it is poured, thereby causing the support ends on both sides of the longitudinal reinforcement 60 or the transverse reinforcement 70 to be unbalanced, affecting the support effect.

[0105] Furthermore, if Fig.16 As shown, when the second supporting groove 823 and the third supporting groove 825 are in an arc shape larger than a semicircle, the top of the circular trajectory surrounded by the arc surface in the second supporting groove 823 is tangent to the bottom surface of the third supporting groove 825, so that the longitudinal steel bars 60 or transverse steel bars 70 supported in the second supporting groove 823 are tangent to the transverse steel bars 70 or longitudinal steel bars 60 supported by the third supporting groove 825. When the second supporting groove 823 and the third supporting groove 825 are U-shaped, the longitudinal steel bars 60 or transverse steel bars 70 supported in the second supporting groove 823 are also tangent to the transverse steel bars 70 or longitudinal steel bars 60 supported by the third supporting groove 825, thereby ensuring the connection between the longitudinal steel bars 60 and the transverse steel bars 70 during pouring, and working together to provide more sufficient supporting force.

[0106] Among them Fig.17 and Fig.18As shown, the third support member 83 includes a fourth supporting member 832, at least one third leg 831 is provided at the bottom of the fourth supporting member 832, and a fourth supporting groove 833 is provided inside the fourth supporting member 832, wherein the fourth supporting groove 833 opens upward, and the fourth supporting groove 833 is an arc shape or a U shape larger than a semicircle, and the longitudinal steel bar 60 or the transverse steel bar 70 supported inside is fully limited by the design larger than a semicircle (when it is an arc shape, since it is larger than a semicircle, the arc in the area above the semicircle will limit the longitudinal steel bar 60 or the transverse steel bar 70 supported inside up and down);

[0107] Furthermore, if Fig.17 As shown, fifth supporting members 834 are symmetrically arranged on both sides of the fourth supporting member 832 in the radial direction, and the two fifth supporting members 834 are connected to the outer axial surface of the fourth supporting member 832, and a fifth supporting groove 835 is opened inside the fifth supporting member 834, and the fifth supporting groove 835 is consistent with the fourth supporting groove 833, and both are arc-shaped or U-shaped larger than a semicircle, and the two fifth supporting grooves 835 and the fourth supporting groove 833 are mutually connected, and the longitudinal steel bars 60 and the transverse steel bars 70 arranged crosswise are stably supported by the fourth supporting member 832 and the two fifth supporting members 834, so as to avoid mold. When the plate body 10 is poured, the longitudinal steel bars 60 and the transverse steel bars 70 are bent under force, and due to the cooperation of the two sides, the cross-arranged longitudinal steel bars 60 and the transverse steel bars 70 are stably supported, thereby preventing the longitudinal steel bars 60 and the transverse steel bars 70 from being bent under force during the pouring of the template body 10. The two fifth supporting members 834 are connected to the longitudinal steel bars 60 or the transverse steel bars 70 for support, so that during pouring, the third supporting member 83 will not be deflected around the center of the fourth supporting groove 833 when subjected to force, thereby causing imbalance in the supporting ends on both sides of the longitudinal steel bars 60 or the transverse steel bars 70, affecting the supporting effect.

[0108] Furthermore, if Fig.18 As shown, when the fourth supporting groove 833 and the fifth supporting groove 835 are in an arc shape larger than a semicircle, the top of the circular trajectory surrounded by the arc surface in the fourth supporting groove 833 is tangent to the bottom surface of the fifth supporting groove 835, so that the longitudinal steel bars 60 or transverse steel bars 70 supported in the fourth supporting groove 833 are tangent to the transverse steel bars 70 or longitudinal steel bars 60 supported by the fifth supporting groove 835. When the fourth supporting groove 833 and the fifth supporting groove 835 are in a U shape, the longitudinal steel bars 60 or transverse steel bars 70 supported in the fourth supporting groove 833 are also tangent to the transverse steel bars 70 or longitudinal steel bars 60 supported by the fifth supporting groove 835, thereby ensuring the connection between the longitudinal steel bars 60 and the transverse steel bars 70 during pouring, and working together to provide more sufficient supporting force.

[0109] Embodiment 6

[0110] like Fig.19As shown, the present embodiment is a non-dismantling wall formwork system in which the non-dismantling wall formworks of multiple embodiments one are combined horizontally and / or vertically. During vertical splicing, the upper end of the traction plate 22 of the connecting piece 20 cooperates with the assembly groove 40 at the lower end of the top formwork body 10 to form a stable connection, and plays a role in limiting the vertical splicing.
