Description

Technical Field

[0001] The present application relates to the technical field of construction engineering, and in particular to a roof formwork support system and a roof formwork construction method. Background Art

[0002] During the construction process, it is necessary to set up a support system and a top slab formwork system, and the support system supports the top slab formwork system.

[0003] The top plate formwork system is generally divided into two types: aluminum formwork and wooden formwork. The aluminum formwork includes multiple finished formworks such as keel plates, corner finished formworks, support plates and main boards. At present, the layout rule of aluminum formwork is generally that the support spacing between two adjacent keel plates is not more than 1.3 meters, and the length of each finished formwork of the top plate formwork does not exceed 1.1 meters. It can be seen that the size of each finished formwork in the related art is small, which will cause the following series of problems: (1) The small size and large number of finished formwork will increase the frequency of operations in each process such as sawing, punching, welding, shaping, inspection, and renovation. For example, processing two 400 mm wide and 800 mm long boards requires one more operation per process than processing one 400 mm wide and 1600 mm long board, resulting in low construction efficiency of the finished formwork and high sawing waste rate. At the same time, the number of end sealing plates required to match the finished formwork is large, and the material consumption is high.

[0004] (2) Multiple finished formworks are spliced ​​together to form a complete top plate formwork. In this way, the top plate formwork forms multiple joints. The more finished formworks there are, the more joints there will be in the top plate formwork. This will lead to poor concrete molding quality.

[0005] (3) The connection between two finished formworks is through pins and pin pieces. The large number of finished formworks will lead to a large loss of pins and pin pieces, low installation efficiency of the top plate formwork, large packaging and loading and unloading volume, and difficult material management.

[0006] In addition, the support frame generally adopts the following support method for the top plate formwork: the support frame is provided with a plurality of support vertical rods, each of which extends from the ground to the top plate formwork, and the top plate formwork is directly supported by the plurality of support vertical rods. With this support method, if the length of the finished formwork of the top plate formwork is increased, it is easy to cause the support strength of the support frame for the top plate formwork to be insufficient, or in order to ensure the support strength of the top plate formwork, the number of support vertical rods needs to be increased, resulting in dense distribution of the support vertical rods, and high transportation cost and material cost. Summary of the invention

[0007] In view of this, the present application provides a top plate formwork support system and a top plate formwork construction method, which can increase the distance between two supporting uprights, increase the size of the formwork components of the top plate formwork, and reduce the number of supporting uprights. At the same time, the support frame can meet the support strength requirements for the top plate formwork.

[0008] According to one aspect of the present application, an embodiment of the present application provides a roof formwork support system, including a roof formwork and a support frame, the roof formwork includes a plurality of keel support plate groups and a plurality of main board groups, the plurality of main board groups and the plurality of keel support plate groups are arranged alternately in sequence, each keel support plate group includes a plurality of keel plates, each main board group includes a plurality of main boards, and each main board is connected to the keel plate; wherein, the length of at least some of the keel plates in the plurality of keel plates ranges from 1.1m to 1.7m; and / or, the length of at least some of the main boards in the plurality of main boards ranges from 1.1m to 1.7m; the support frame includes a plurality of support units, the plurality of support units are connected to the plurality of keel support plate groups in a one-to-one correspondence, each support unit includes a first support truss and two support uprights, the first support truss includes a truss support rod and a truss connection frame, the truss connection frame is a polygonal structure, the truss connection frame is connected to the two support uprights, the truss support rod is connected to the truss connection frame and is arranged parallel to the support uprights.

[0009] Through the above-mentioned arrangement, the truss support rods and the support uprights jointly support the top plate formwork. There is no need to arrange extra support uprights between the two support uprights of the support unit, which can reduce the number of support uprights of each support unit and increase the distance between two adjacent support units in multiple support units. The pressure is shared by multiple "edges" of the truss connecting frame, thereby ensuring the bearing capacity of each support unit while reducing the number of support uprights. At the same time, the length of the keel plate and the main board of the top plate formwork can be increased, the number of keel plates and the main board can be reduced, the construction efficiency and turnover efficiency of the top plate formwork can be improved, and the labor intensity can be reduced.

[0010] In at least one embodiment, the multiple keel plates of each keel support plate group include at least one first keel plate, the length of the first keel plate ranges from 1.1m to 1.7m, and the first keel plate is connected to the truss support rod; each keel support plate group includes at least two support plates, the two support plates are located at both ends of the first keel plate and connected to the first keel plate; wherein the two support uprights of each support unit are connected one-to-one with the two support plates of each keel support plate group.

[0011] Through the above arrangement, the two support plates can realize early dismantling of the first keel plate, and the truss support rod is connected to the first keel plate, and the two support vertical rods are connected to the two support plates. Since the two support plates are connected to the first keel plate, the supporting strength of the first keel plate with a longer length can be guaranteed.

[0012] In at least one embodiment, in each support unit: there is one truss support rod, which is located at the middle position of the first keel plate along the length direction of the first keel plate; or, there are multiple truss support rods, each of which is connected to the first keel plate, and each of which is spaced apart along the length direction of the first keel plate.

[0013] By arranging a truss support rod in the middle of the first keel plate, the force distribution of the first keel plate can be uniform, and the support strength of the keel support plate group can be further improved. Since the keel support plate group and the main plate group are connected to each other, the support strength of the entire top plate template can be improved. By arranging multiple truss support rods and supporting the top plate template together through multiple truss support rods, the support strength of the first support truss to the keel support plate group can be further increased.

[0014] In at least one embodiment, the support unit also includes a first adjustable top support and a second adjustable top support, the first adjustable top support is correspondingly arranged on each supporting upright, the first adjustable top support is passed through the supporting upright and the height of the first adjustable top support is adjustable; the second adjustable top support is correspondingly passed through the truss support rod of the first supporting truss, and the height of the second adjustable top support is adjustable; wherein the first adjustable top support is connected to the support plate; the second adjustable top support is connected to the first keel plate.

[0015] By setting an adjustable top support, the keel support plate group is pre-arched upward to a certain height, so as to offset the partial deformation of the top plate template applied by the concrete when pouring concrete, thereby reducing the downward bending deformation of the top plate template. Combined with the setting of the truss connection frame, when the top plate template is subjected to the pressure of the concrete, the structure of the support frame will be more stable.

[0017] Since the support uprights are connected to the support plates, the distance between the two support uprights is the sum of the length of the keel plate or the main plate and half the length or width of the support plate. By limiting the size of the support plate to 100mm to 200mm and combining the length of part of the keel plate and part of the main plate to a value range of 1.1m-1.7m, the distance between the two support uprights can be within 2m. In this way, the first keel plate can be removed early and the supporting strength of the support frame to the top plate formwork is guaranteed.

[0018] In at least one embodiment, the width of each support plate is the same as the width of the first keel plate.

[0019] This arrangement reduces the width types of the support plate and the first keel plate, improves the processing and manufacturing efficiency of the support plate and the first keel plate, and the support plate and the first keel plate can be arranged flush in the width direction.

[0021] By providing reinforcing ribs, the structural strength of each keel plate and each main plate is improved, so that the supporting strength of the top plate formwork itself to the concrete can be guaranteed while the length of the formwork components is lengthened.

[0022] In at least one embodiment, the multiple keel plates and the multiple main boards each include a plurality of connecting ribs, the length direction of each connecting rib is arranged at an angle with the length direction of the reinforcing rib, and the multiple connecting ribs are arranged at intervals along the length direction of the template body.

[0023] By setting connecting ribs, the structural strength and bearing capacity of the formwork body can be further improved.

[0024] In at least one embodiment, the truss support rods are connected to connecting ribs or reinforcing ribs.

[0025] In this way, when the keel plate is provided with reinforcing ribs / connecting ribs, the connection between the truss support rod and the keel plate is achieved.

[0029] Through the above arrangement, the pressure can be shared by multiple "sides" of the truss connecting frame, thereby improving the supporting strength of each supporting unit. No additional supporting poles are required between the two supporting poles of the supporting unit, thereby increasing the supporting distance between the two supporting poles of each supporting unit and reducing the number of supporting poles of each supporting unit.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0046] In the related technical means, the length of each template component (finished template) of the top plate template system of the aluminum template is generally less than 1.1m. In this way, the length of each template component is short and the size is small, which will lead to low construction efficiency and installation efficiency of the top plate template, and there are many joints between the template components. In addition, the support frame in the related technical means directly supports the top plate template through multiple support vertical poles of multiple support units, and according to the requirements of the building standard specifications, the distance between the multiple support units and the distance between the two support vertical poles of each support unit need to be kept within 1.3m to ensure the support strength of the support frame to the top plate template. In this way, each support unit needs to use multiple support vertical poles, which need to be set in a large number. The support vertical poles used in this arrangement form are more materials, and the transportation cost and material cost are high. Among them, if the length of the keel board of the top plate template is increased, the distance between the two support vertical poles of each support unit must be increased. Similarly, if the length of the main board of the top plate template is increased, the distance between the support vertical poles of the two support units must be increased. However, if the distance between the support vertical poles of the support frame is directly increased, the support strength of the support unit of the support frame will be insufficient.

[0047] An embodiment of the present application provides a roof plate formwork support system, including a roof plate formwork and a support frame, the roof plate formwork includes multiple keel support plate groups and multiple main board groups, the multiple main board groups and the multiple keel support plate groups are arranged alternately in sequence, each keel support plate group includes multiple keel plates, each main board group includes multiple main boards, and each main board is connected to the keel plate; the support frame includes multiple support units, the multiple support units are connected to the multiple keel support plate groups one by one, each support unit includes a first support truss and two support uprights, the first support truss includes a truss support rod and a truss connection frame, the truss connection frame is a polygonal structure, and the truss connection frame is connected to the two support uprights.

[0048] Through the above-mentioned arrangement, the truss support rods and the support uprights jointly support the top plate formwork. When supporting the top plate formwork, there is no need to arrange extra support uprights between the two support uprights of the support unit, which can reduce the number of support uprights of each support unit and increase the distance between two adjacent support units in multiple support units. The pressure is shared by multiple "edges" of the truss connecting frame, thereby reducing the number of support uprights while ensuring the bearing capacity of each support unit. At the same time, the length of the keel plate and the main board of the top plate formwork can be increased, the number of keel plates and the main board can be reduced, the construction efficiency and turnover efficiency of the top plate formwork are improved, and the labor intensity is reduced.

[0049] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features in the following embodiments and examples can be combined with each other.

[0050] See also Figure 1 and Figure 2 An embodiment of the present application provides a roof formwork support system, comprising: a roof formwork 1 and a support frame 2.

[0051] In the related art, each support unit includes three support uprights and two cross bars, and the top of two adjacent support uprights are connected by a cross bar to ensure the stability of the structure between the two adjacent support uprights. However, if the distance between the two support uprights is increased, only connecting the two support uprights with a cross bar cannot well ensure the structural stability and support strength of the support uprights.

[0052] See also Figure 1 and Figure 2 In the present application, the support frame 2 includes a plurality of support units 30, and the plurality of support units 30 are connected one-to-one with the plurality of keel support plate groups 10. Each support unit 30 includes a first support truss 31 and two support uprights 32. The first support truss 31 includes a truss support rod 310 and a truss connection frame 311. The truss connection frame 311 is a polygonal structure. The truss connection frame 311 is connected with the two support uprights 32. The truss support rod 310 is connected to the truss connection frame 311 and is arranged parallel to the support uprights 32.

[0053] Through the above-mentioned arrangement, the truss support rod 310 and the support vertical rod 32 jointly support the top plate formwork 1. When supporting the top plate formwork 1, the truss connection frame 311 replaces the original cross rod, and the truss support rod 310 replaces the middle support vertical rod of the original three support vertical rods. In this way, the number of support vertical rods 32 of each support unit 30 can be reduced, and the distance between two adjacent support units 30 in multiple support units 30 can be increased. The pressure is shared by multiple "edges" of the truss connection frame 311, so as to reduce the number of support vertical rods 32 while ensuring the bearing capacity of each support unit. At the same time, the length of the keel plate 100 and the main board 200 of the top plate formwork can be increased, and the number of keel plates 100 and the main board 200 can be reduced, thereby improving the construction efficiency and turnover efficiency of the top plate formwork 1 and reducing labor intensity.

[0054] See also Figure 2 and Figure 4The top plate formwork 1 includes a plurality of keel support plate groups 10 and a plurality of main plate groups 20, and the plurality of main plate groups 20 and the plurality of keel support plate groups 10 are arranged alternately in sequence, each keel support plate group 10 includes a plurality of keel plates 100, each main plate group 20 includes a plurality of main plates 200, and each main plate 200 is connected to the keel plate 100; wherein, the length of at least some of the keel plates 100 in the plurality of keel plates 100 is in the range of 1.1m to 1.7m; and / or, the length of at least some of the main plates 200 in the plurality of main plates 200 is in the range of 1.1m to 1.7m. The above arrangement increases the length of the keel plates 100 and the main plates 200, thereby reducing the number of formwork components of the top plate formwork 1, improving the construction efficiency and installation efficiency of the formwork components of the top plate formwork 1, reducing the joints between formwork components, and improving the quality of concrete molding.

[0055] In some embodiments, the roof template 1 is an aluminum template.

[0056] In some embodiments, a plurality of support units 30 are distributed in an array.

[0057] In some embodiments, the plurality of support units 30 are distributed along a first direction; or, the plurality of support units 30 are distributed along a second direction, wherein the first direction is perpendicular to the second direction, and the first direction is the distribution direction of the two support poles 32 in one support unit 30 .

[0058] The arrangement of the plurality of support units 30 may be selected according to the actual building space.

[0059] Specifically, the support pole 32 is used to connect with the support base surface, and the first support truss 31 is arranged on a side of the support pole 32 away from the support base surface. The support base surface is the ground.

[0060] In some embodiments, the truss support rod 310 is passed through the truss connection frame 311, so that the truss support rod 310 can act as a reinforcement of the truss connection frame 311, while supporting the support frame 2 to support the top plate formwork 1, and at the same time, increase the supporting strength of the first supporting truss 31.

[0061] In some embodiments, the truss connection frame 311 is symmetrically arranged with the first preset axis as the symmetry axis; wherein the first preset axis is located at the middle position of the truss connection frame 311 along the length direction of the support uprights 32, and the first preset axis extends along the distribution direction of the two support uprights 32. In this arrangement, the structure of the truss connection frame 311 is symmetrical up and down, so that the force distribution of the truss connection frame 311 is uniform, thereby preventing the truss connection frame 311 from being fractured due to stress concentration.

[0062] In some embodiments, the truss connection frame 311 is symmetrically arranged with the second preset axis as the symmetry axis; wherein the second preset axis is located in the middle position of the truss connection frame 311 along the length direction of the support pole 32, and the second preset axis extends along the length direction of the support pole 32. In this arrangement, the structure of the truss connection frame 311 is bilaterally symmetrical, so that the force distribution of the truss connection frame 311 is uniform, thereby preventing the truss connection frame 311 from being fractured due to stress concentration.

[0063] In some embodiments, the truss connection frame 311 includes three connection rods 312, and the three connection rods 312 form a triangular structure, which is an isosceles triangle structure. In this way, the truss connection frame 311 can form a left-right symmetrical structure so that the force distribution of the truss connection frame 311 is uniform, thereby preventing the truss connection frame 311 from breaking due to stress concentration.

[0064] Preferably, the truss connection frame 311 is symmetrically arranged with the first preset axis as the symmetry axis, and the truss connection frame 311 is symmetrically arranged with the second preset axis as the symmetry axis, so that the truss connection frame 311 forms a structure that is symmetrical up and down and left and right, and further makes the force distribution of the truss connection frame 311 uniform, thereby preventing the truss connection frame 311 from stress concentration and fracture.

[0065] Specifically, the second preset axis is the central axis of the truss support rod 310 , and the first preset axis is perpendicular to the second preset axis. The extension direction of the first preset axis is the same as the distribution direction of the two support poles 32 of one support unit 30 .

[0066] In some embodiments, see Figure 2 and Figure 3 The truss connection frame 311 includes four connection rods 312 to form a quadrilateral structure. The four connection rods 312 share the pressure, so that the support strength of the truss connection frame 311 of the first support truss 31 can be guaranteed.

[0067] Preferably, the four connecting rods 312 have the same length to form a diamond structure, so that the truss connecting frame 311 forms a vertically symmetrical and left-right symmetrical structure, thereby making the force distribution of the truss connecting frame 311 uniform.

[0068] In some embodiments, the truss connection frame 311 includes six connection rods 312, and the six connection rods 312 form a hexagonal structure. By setting the truss connection frame 311 as a hexagonal structure, it can be applied to the situation where the distance between the two support poles 32 is far, thereby improving the use range of the support truss.

[0069] See also Figure 2 and Figure 4In some embodiments, the multiple keel plates 100 of each keel support plate group 10 include at least one first keel plate 101, the length of the first keel plate 101 ranges from 1.1m to 1.7m, and the first keel plate 101 is connected to the truss support rod 310; each keel support plate group 10 includes at least two support plates 110, the two support plates 110 are located at both ends of the first keel plate 101 and connected to the first keel plate 101; wherein, the two support uprights 32 of each support unit 30 are connected to the two support plates 110 of each keel support plate group 10 in a one-to-one correspondence. By providing two support plates 110, the early removal of the first keel plate 101 can be achieved, and the truss support rod 310 is connected to the first keel plate 101, and the two support uprights are connected to the two support plates 110. Since the two support plates 110 are connected to the first keel plate 101, the support strength of the first keel plate 101 with a longer length can be ensured.

[0070] In some embodiments, the multiple keel plates 100 of each keel support plate group 10 further include two second keel plates 102, the length of each second keel plate 102 is less than or equal to the length of the first keel plate 101, each support plate 110 is located between the first keel plate 101 and the second keel plate 102, one end of each second keel plate 102 is connected to the corner formwork component 40, and the other end of each second keel plate 102 is connected to the support plate 110. In addition, the support rod 32 is connected to the support plate 110, and the vertical wall is connected to the corner formwork component 40. In this way, through the arrangement of the corner formwork component 40 and the support rod 32, the vertical wall and the support rod 32 can jointly provide support force for the second keel plate 102, thereby ensuring the support strength of the second keel plate 102. Among them, after the first keel plate 101 is arranged, the length of the remaining space is less than the length of the first keel plate 101. At this time, the second keel plate 102 can be arranged in the remaining space to meet the layout requirements of the top plate template 1, and the first keel plate 101 is used as a plate of standard length, which reduces the length types of the plates and improves the layout efficiency.

[0071] In some embodiments, there is one first keel plate 101 , and two second keel plates 102 are connected to two ends of the first keel plate 101 through two first supporting plates 1101 , respectively.

[0072] In some embodiments, Fig.10 As shown, there are multiple first keel plates 101 , and two first keel plates 101 among the multiple first keel plates 101 are connected to two second keel plates 102 in a one-to-one correspondence through two first supporting plates 1101 , respectively.

[0073] In some embodiments, Fig.10As shown, each keel support plate group 10 includes at least one second support plate 1102 , and the second support plate 1102 is used to connect to the support system. There are multiple first keel plates 101 , and two adjacent first keel plates 101 are connected by a second support plate 1102 .

[0074] By disposing the first support plate 1101 and the second support plate 1102 , early removal of the first keel plate 101 and the second keel plate 102 is achieved.

Through the above arrangement, in combination with the arrangement of a plurality of keel plates and a plurality of main plates, the length of the keel plates and the main plates is increased, and the number of formwork components is reduced, thereby improving the construction efficiency and installation efficiency of the top plate formwork, and ensuring the support strength of the top plate formwork itself for concrete while the keel plates and the main plates become longer.

[0079] In some embodiments, in each support unit 30, there is one truss support rod 310, and one truss support rod 310 is located at the middle position of the first keel plate 101 along the length direction of the first keel plate 101. By arranging one truss support rod 310 at the middle position of the first keel plate 101, the force distribution of the first keel plate 101 can be uniform, and the support strength of the keel support plate group 10 is further improved. Since the keel support plate group 10 and the main plate group 20 are connected to each other, the support strength of the entire top plate template 1 is improved.

[0080] In some embodiments, in each support unit 30, there are multiple truss support rods 310, each of which is connected to the first keel plate 101, and the multiple truss support rods 310 are arranged at intervals along the length direction of the first keel plate 101. By arranging multiple truss support rods 310, the support strength of the first support truss 31 on the keel support plate group 10 can be further increased.

[0081] Optionally, multiple truss support rods 310 are arranged at equal intervals along the length direction of the first keel plate 101, so that the force on the first keel plate 101 can be uniform; or, multiple truss support rods 310 are concentrated in the place where the force is concentrated on the first keel plate 101 to ensure the reliability of the first support truss 31 in supporting the first keel plate 101.

[0082] In some embodiments, see Figure 2 and Figure 3 The truss connection frame 311 is a diamond structure, and the truss support rod 310 is one, and one truss support rod 310 is arranged on the diamond structure to divide the diamond structure into two triangular structures. In this way, the diamond structure forms two stable triangular structures, which improves the force stability of the truss connection frame 311.

[0084] By setting an adjustable top support, the keel support plate group 10 is pre-arched upward to a certain height, so as to offset the partial deformation of the top plate template 1 applied by the concrete when pouring concrete, thereby reducing the downward bending deformation of the top plate template 1. Combined with the setting of the truss connection frame 311, when the top plate template 1 is subjected to the pressure applied by the concrete, the structure of the support frame 2 will be more stable. And by setting the second adjustable top support 34, when pouring concrete, the downward bending deformation of the first keel plate 101 with a longer length can be reduced to ensure the structural stability of the top plate template 1 during the pouring process.

[0085] See also Figure 2 and Figure 3In some embodiments, the truss support rod 310 has a through hole, and the second adjustable top support 34 includes a screw rod 340, a bracket 341 and a nut 342.

The nut 342 is connected to the truss support rod 310 and rotates relative to the truss support rod 310. By setting an adjustable top support, the nut 342 is rotated to adjust the length / height of the screw rod 340, so that the top plate formwork 1 is pre-arched upward by a certain height, so as to offset the partial deformation of the top plate formwork 1 applied by concrete when pouring concrete, thereby reducing the downward bending deformation of the first keel plate 101 of the top plate formwork 1. Combined with the setting of the truss connection frame 311, when the top plate formwork 1 is subjected to the pressure applied by concrete, the structure of the support frame 2 will be more stable.

[0086] In some embodiments, the nut 342 of the second adjustable jack 34 abuts against the end of the truss support rod 310 .

[0088] In some embodiments, the nut 342 of the first adjustable jack 33 abuts against the end of the supporting pole 32 .

[0089] In some embodiments, the bracket 341 is in the shape of a flat plate and is used to support the keel support plate assembly 10 .

[0090] Optionally, an anti-skid rubber strip is provided on the upper surface of the bracket 341, and the anti-skid rubber strip is used to increase the friction between the keel support plate group and the bracket 341, and the anti-skid rubber strip has a shock-absorbing effect.

[0091] In other embodiments, the bracket 341 has a limiting support groove. By setting the limiting support groove, the moving position of the keel support plate group 10 can be limited to position the keel support plate group 10, thereby improving the connection stability and reliability between the keel support plate group 10 and the bracket 341.

[0092] See also Figure 2 and Figure 3In some embodiments, the truss connection frame 311 includes: two connection frames 22, which are connected to two supporting uprights 32 in a one-to-one correspondence, and the two connection frames 22 each include a first connection rod 221 and a second connection rod 222 that are connected to each other, and the first connection rod 221 and the second connection rod 222 are arranged at an angle; wherein one of the first connection rod 221 and the second connection rod 222 of each connection frame 22 is connected to the corresponding supporting upright 32.

[0093] Through the above arrangement, the connection between the truss connection frame 311 and the support pole 32 is achieved, and there is only one connection position between the truss connection frame 311 and the support pole 32. The connection structure between the truss connection frame 311 and the support pole 32 is simple.

Combined with the arrangement of the truss reinforcement rod 23 and the two truss support rods 310, the hexagonal truss connection frame 311 forms a plurality of stable triangular structures, thereby further improving the support strength of the first support truss 31.

[0096] In the relevant technology, according to the concrete strength requirements when the formwork components are removed, the formwork removal conditions for the plate structure are that when the structure span is less than or equal to 2m, the formwork can be removed when it reaches 50% of the designed concrete strength grade value; when the span is greater than 2m and less than or equal to 8m, the formwork can be removed when it reaches 75% of the designed concrete strength grade value; when the span is greater than 8m, the formwork can be removed when it reaches 100% of the designed concrete strength grade value. The architectural aluminum formwork system increases the support points, and the support poles are still retained after the formwork is removed, which is equivalent to reducing the structural span. The support spacing of the support poles is arranged within 2m, which can achieve early removal of the formwork components.

[0097] In some embodiments, in at least some of the support units 30, the distance between the central axes of the support poles 32 of two adjacent support units 30 along the second direction is in the range of 1.3m to 1.8m, and the second direction is perpendicular to the distribution direction of the two support poles 32 in one support unit 30; and / or, the distance between the central axes of the two support poles 32 of at least some of the support units 30 is in the range of 1.3m to 1.8m.

[0098] Through the above-mentioned settings, the present application can ensure the supporting strength of the top plate formwork 1 through the setting of the first supporting truss 31, reduce the bending deformation of the top plate formwork 1, and at the same time increase the distance between the two supporting uprights 32 in different directions, reduce the number of supporting uprights 32 in two different directions, further reduce the production cost of the support frame 2, and control the distance between the two supporting uprights 32 within 2m, so as to realize the early dismantling of the formwork components.

[0099] In some embodiments, in at least some of the support units 30, the distance between the central axes of the support poles 32 of two support units 30 adjacent to each other along the second direction is 1.8 m, and the distance between the central axes of the two support poles 32 of at least some of the support units 30 is 1.8 m. In this way, the support strength of the support frame 2 to the top plate formwork 1 can be ensured, and the top plate formwork 1 can be dismantled early. At the same time, the distance between the two support poles 32 is increased to a certain extent, and the number of support poles 32 is reduced.

The specific value of the distance between the support unit 30 of the second support group and the support unit 30 of the adjacent first support group is determined according to the spacing of the remaining space.

[0102] In some embodiments, each first support group and second support group includes multiple first support units and one second support unit, the distance between the central axes of the two support poles 32 of each first support unit is 1.8m, and the distance between the central axes of the two support poles 32 of the second support unit is less than or equal to 1.8m.

[0103] Among them, multiple first support units are arranged in sequence until the spacing of the remaining space is less than 1.8m, and then the second support unit is arranged. The specific value of the distance between the central axes of the two support poles 32 of the second support unit is determined according to the spacing of the remaining space.

[0104] In some embodiments, the support frame 2 includes a plurality of second support trusses 3 , each of which is connected to the support uprights 32 of two adjacent support units 30 .

[0105] In some embodiments, the structure of each second support truss 3 is the same as that of the first support truss 31. The structure of each second support truss 3 is similar to that of the first support truss 31, and the truss connection frame 311 of the second support truss 3 and the truss connection frame 311 of the first support truss 31 jointly share the pressure of the top plate formwork 1, so that the support strength of the support frame 2 on the top plate formwork 1 can be further improved.

[0106] In some embodiments, each second support truss 3 is a crossbar structure. Since each support unit 30 is provided with a first support truss 31, the support strength of the support frame 2 has met the requirements. At this time, each second support truss 3 is a crossbar structure, which can reduce the manufacturing materials and manufacturing process of the support frame 2 and reduce the production cost.

[0107] In some embodiments, the structures of some of the plurality of second supporting trusses 3 are similar to the structures of the first supporting trusses 31 , and the structures of another part of the second supporting trusses 3 are crossbar structures.

[0108] See also Figure 1 and Figure 2 In some embodiments, the support frame 2 adopts a buckle support system, and each support pole 32 is provided with a plurality of connecting buckles 400 , and the plurality of connecting buckles 400 are arranged at intervals along the length direction of the support pole 32 .

[0109] In some embodiments, the first connecting rod 221 of the connecting frame 22 is connected to the outer circumference of the second connecting rod 222, and a connecting head is provided on the second connecting rod 222. The connecting head on the second connecting rod 222 is fixedly connected to the connecting disk buckle 400 through a pin sheet.

[0110] Through the above-mentioned arrangement, a fixed connection between the supporting uprights 32 and the truss connecting frame 311 is achieved, and the outer peripheral surfaces of the first connecting rod 221 and the second connecting rod 222 are connected, which can ensure the connection area between the first connecting rod 221 and the second connecting rod 222, thereby ensuring the stability of the connection between the first connecting rod 221 and the second connecting rod 222.

[0111] Specifically, the first connecting rod 221 and the second connecting rod 222 of each connecting frame 22 are welded together with the outer peripheral surface of the truss support rod 310. This arrangement can ensure the connection area between the first connecting rod 221 / the second connecting rod 222 and the truss support rod 310, and ensure the connection stability between the first connecting rod 221 / the second connecting rod 222.

[0112] In some embodiments, the first connecting rod 221 is welded to the outer circumference of the second connecting rod 222 to stabilize the connection structure between the first connecting rod 221 and the second connecting rod 222 .

[0113] In some embodiments, the second connecting rod 222 is connected to the outer circumference of the first connecting rod 221. Specifically, the second connecting rod 222 is welded to the outer circumference of the first connecting rod 221.

[0114] In some embodiments, the first connecting rod 221 and the second connecting rod 222 are arranged at an acute angle. Through the above arrangement, the end of the polygonal structure at the acute angle can be connected to the support pole 32, so that the truss connection frame 311 can adapt to the longer distance between the two support poles 32.

[0115] In some embodiments, the angle between the first connecting rod 221 and the second connecting rod 222 ranges from 10° to 50°.

[0116] In some embodiments, see Figure 1 The support frame 2 also includes: a first connecting cross bar 401 and a second connecting cross bar 402, each first connecting cross bar 401 connects the supporting uprights 32 of two adjacent supporting units 30 along the second direction; the second direction is perpendicular to the distribution direction of the two supporting uprights 32 in one supporting unit 30; each second connecting cross bar 402 is connected to the two supporting uprights 32 of each supporting unit 30.

[0117] The structural stability of the entire support frame 2 is ensured by the arrangement of the first connecting cross bar 401 and the second connecting cross bar 402 .

[0118] In some embodiments, see Figure 1 The support frame 2 further includes a reinforcing rod 5; two first connecting cross bars 401 are provided, and the two first connecting cross bars 401 and the two supporting vertical bars 32 of two adjacent supporting units 30 form a first rectangular structure, and the reinforcing rod 5 connects two diagonal corners of the first rectangular structure. By providing the reinforcing rod 5, a stable triangular structure is formed between the reinforcing rod 5, the first connecting cross bar 401 and the supporting vertical bars 32, further improving the structural strength of the entire support frame 2.

[0119] In some embodiments, the support frame 2 further includes a reinforcing rod 5; two second connecting cross bars 402 are provided, and the two second connecting cross bars 402 form a second rectangular structure with two supporting vertical bars 32 of the same supporting unit 30; and the reinforcing rod 5 connects two diagonal corners of the second rectangular structure. Through the above arrangement, a stable triangular structure is formed between the reinforcing rod 5, the second connecting cross bar 402 and the supporting vertical bars 32, further improving the structural strength of the entire support frame 2.

[0120] In some embodiments, connecting heads are provided at both ends of the reinforcing rod 5, connecting heads are provided at both ends of the first connecting cross bar 401, and connecting heads are provided at both ends of the second connecting cross bar 402, wherein: the reinforcing rod 5, the second connecting cross bar and the supporting vertical rod are connected by connecting disc buckles 400 and pins.

[0121] Specifically, the pin piece is passed through the connecting head of the reinforcing rod 5, the connecting head of the second connecting cross bar 402 and the connecting disc buckle 400; and / or the reinforcing rod 5, the first connecting cross bar 401 and the supporting vertical rod 32 are connected through the connecting disc buckle 400 and the pin piece, specifically, the pin piece is passed through the connecting head of the reinforcing rod 5, the connecting head of the first connecting cross bar 401 and the connecting disc buckle 400.

[0122] In some embodiments, both ends of the reinforcing rod 5 are flat structures. This arrangement facilitates the connection between the reinforcing rod 5 and the connectors on the reinforcing rod 5, increases the connection area between the reinforcing rod 5 and its connectors, and makes the connection structure between the reinforcing rod 5 and its connectors more stable.

[0123] In some embodiments, the support frame 2 includes an adjustable base support 300, which is disposed at the bottom of the support post 32. The adjustable base support 300 includes a base support screw, a base support nut and a base support seat. The base support screw is adjustably positioned on the support post 32, the base support screw is threadedly connected to the base support nut, the base support nut is sleeved on the support post 32 and rotatably connected to the support post 32, the base support seat is fixedly connected to the base support screw, and the base support seat is used to contact the support base surface.

[0124] In some embodiments, the support plate 110 is a rectangular structure; wherein: the length of the support plate 110 ranges from 100 mm to 200 mm; and / or the width of the support plate 110 ranges from 100 mm to 200 mm. Since the support posts are connected to the support plate 110, the distance between the two support posts 32 is the sum of the length of the keel plate 100 or the main board 200 and half the length or width of the support plate 110. By limiting the size of the support plate 110 to 100 mm to 200 mm, and combining the length of part of the keel plate 100 and part of the main board 200 with a range of 1.1 m to 1.7 m, the distance between the two support posts 32 can be within 2 m, so as to achieve early removal of the first keel plate 101, and ensure the support strength of the support frame 2 to the top plate formwork 1.

[0125] In some embodiments, the support plate 110 is a square plate.

[0126] In some embodiments, the length and width of the square plate are both 200 mm. The top plate formwork 1 is supported by a support system (support frame 2), and the length of each first main plate 201 is 1.6 m; the length of the first keel plate 101 between two adjacent support plates 110 in the first direction is 1.6 m. This arrangement can ensure that the distance between the central axes of the two support plates 110 is 1.8 m (within 2 m), thereby ensuring the support strength of the support system (support frame 2) for the top plate formwork 1.

[0127] In some embodiments, the length and width of the support plate 110 are both 100 mm; the length of each first main plate 201 is 1.7 m; the length of the first keel plate 101 between two adjacent support plates 110 in the first direction is 1.7 m. This arrangement can ensure that the distance between the central axes of the two support plates 110 is 1.8 m (within 2 m), thereby ensuring the support strength of the support system (support frame 2) to the top plate formwork 1.

[0128] In some embodiments, the width of each support plate 110 is the same as the width of the first keel plate 101. In this way, the width types of the support plates 110 and the first keel plates 101 are reduced, the processing efficiency of the support plates 110 and the first keel plates 101 is improved, and the support plates 110 and the first keel plates 101 can be arranged flush in the width direction.

[0129] In some embodiments, see Figure 5 The support plate 110 and the second keel plate 102 are connected via a pin 500 and a pin sheet 501 .

[0130] See also Figure 2 In some embodiments, each support plate 110 has a first limiting groove 111, and two support uprights 32 are connected to the inner bottom wall of the first limiting groove 111 of the corresponding support plate 110; the first keel plate 101 has a second limiting groove 112, and the truss support rod 310 is connected to the inner bottom wall of the second limiting groove 112. The setting of the limiting groove can ensure the reliability of the connection between the rod and the template component.

[0131] See also Figure 3 and Figure 6 In some embodiments, the plurality of keel plates 100 and the plurality of main plates 200 each include: a template body 120 having a groove portion 121; and reinforcing ribs 122, which are arranged on the inner bottom wall of the groove portion 121 and extend along the length direction of the template body 120. By providing the reinforcing ribs 122, the structural strength of each keel plate 100 and each main plate 200 is improved, so that the supporting strength of the top plate template for concrete can be ensured while the template component becomes longer.

[0132] See also Figure 3 and Figure 7 In some embodiments, a plurality of keel plates 100 or a plurality of main plates 200 are divided into: a plurality of first template components 130, the template body 120 of each first template component 130 is a first template body, the reinforcement rib 122 of each first template component 130 is a first reinforcement rib 1301, and each first template component 130 includes a plurality of first reinforcement ribs 1301, and the plurality of first reinforcement ribs 1301 are spaced apart along the width direction of the groove bottom plate 1011 of the first template body.

[0133] By setting up multiple first reinforcing ribs 1301, multiple first reinforcing ribs 1301 jointly share the pressure exerted by the concrete on the top plate formwork 1, thereby reducing the bending deformation of the groove bottom plate of the formwork component, and further improving the supporting strength of the formwork component to ensure the supporting strength of the top plate formwork for the concrete.

[0134] In some embodiments, the groove portion 121 of the first template body has a groove side plate 1012 connected to the groove bottom plate 1011, and the height of the first reinforcing rib 1301 is the same as the width of the groove side plate 1012 of the first template body. This arrangement can ensure the structural strength of the first template component 130 to ensure the supporting strength of the top plate template for concrete.

[0135] See also Figure 3 and Figure 8 In some embodiments, a plurality of keel plates 100 or a plurality of main boards 200 are divided into: a plurality of second template components 140, wherein the width of the second template component 140 is smaller than the width of the first template component, the template body 120 of each second template component 140 is a second template body, and the reinforcement rib 122 of each second template component 140 is a second reinforcement rib 1401; wherein the height of the second reinforcement rib 1401 is smaller than the height of the first reinforcement rib.

[0136] Since the width of the second template component 140 is relatively small and the height of the second reinforcement rib 1401 is smaller than the height of the first reinforcement rib, the second template component 140 reduces the material used for the reinforcement rib while meeting the support strength, thereby reducing the weight of the top plate template 1.

[0137] In some embodiments, there is one second reinforcing rib 1401, and one second reinforcing rib 1401 is arranged in the middle of the width direction of the groove bottom plate 1011 of the second template body. The second reinforcing rib 1401 is arranged in the middle of the groove bottom plate 1011 to strengthen the support strength of the second template component 140, so that the force on the groove bottom plate is uniform.

[0138] In some embodiments, the groove portion 121 of the second template body has two groove side plates 1012 connected to the groove bottom plate 1011, and the two groove side plates 1012 are arranged opposite to each other, wherein: the end of the second reinforcement rib 1401 away from the groove bottom plate 1011 of the second template body is located at 1 / 4 to 1 / 2 of the width of the groove side plate 1012 of the second template body. This arrangement reduces the amount of reinforcement ribs while meeting the support strength requirements, thereby reducing the weight of the top plate template 1; and / or, each second template component 140 has two protrusions 124, and the two protrusions 124 are connected to the inner sides of the two groove side plates 1012 in a one-to-one correspondence. This arrangement improves the bending resistance of the second template component 140.

[0139] In some embodiments, each reinforcing rib 122 is a hollow structure. By setting each reinforcing rib 122 as a hollow structure, the material usage of the reinforcing rib 122 is reduced, and the weight of the top plate formwork 1 is reduced.

[0140] See also Figure 3 In some embodiments, the plurality of keel plates 100 and the plurality of main plates 200 each include: a plurality of connecting ribs 123, the length direction of each connecting rib 123 being arranged at an angle to the length direction of the reinforcing rib 122, and the plurality of connecting ribs 123 being arranged at intervals along the length direction of the formwork body 120. By arranging the connecting ribs 123, the supporting strength of the formwork body 120 for concrete can be further improved.

[0141] In some embodiments, the connecting ribs 123 and the reinforcing ribs 122 are arranged vertically, wherein the connecting ribs 123 extend along the width direction of the trough bottom plate, and the reinforcing ribs 122 extend along the length direction of the trough bottom plate 1011 .
