Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a reinforcing device for building construction templates of arc-shaped walls or beams. Background Art

[0002] At present, curved lines are common in building design, which can make buildings look more elegant, soft and warm, and have a sense of spatial art. However, curved structures with a large degree of curvature are more difficult to construct during the main structure of the building.

[0003] When the construction unit is constructing the main structure, there are two common practices for arc structure construction;

[0004] The first solution: The reinforcement of curved reinforced concrete walls or beams generally uses curved formwork as the support surface, wooden squares as vertical ribs, steel bars as horizontal ribs, and steel pipes fixed outside the steel bars as vertical back ribs, and then reinforced with tension bolts. This reinforcement method is not easy to control during operation. During construction, it is necessary to manually control the bending degree of the steel bars at the construction site to ensure the curvature of the curved reinforced concrete wall or beam. When the radius of curvature of the arc is small, large-diameter steel bars are difficult to bend, and the elasticity of the steel bars during manual bending can easily cause unsafe factors.

[0005] The second option: reinforced concrete curved walls or beams use specially customized curved reinforced square steel pipe materials, which are processed in the factory and then shipped to the construction site for use. However, for construction projects with few curved shapes, this approach is too costly and uneconomical. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a reinforcement device for building construction templates of curved walls or beams, which has the effects of good economy, safety and reliability, convenience and practicality and can be used for various curved structures.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: A reinforcement device for a building construction template of a curved wall or beam, comprising:

[0010] Wooden squares are arranged at intervals between the arc-shaped template and the supporting square steel;

[0011] A fixing piece connects the supporting square steels on the inner and outer sides.

[0012] In a preferred example, the utility model can be further configured as follows: the fixing member is a tension bolt that passes through the arc-shaped template and the supporting square steel.

[0013] In a preferred example, the utility model can be further configured as follows: the wooden square includes an inner support block, an outer support block and an adjustment mechanism, the inner support block abuts against the outer side of the arc-shaped template, the outer support block abuts against the inner side of the supporting square steel, and the adjustment mechanism is used to control the distance between the inner support block and the outer support block.

[0014] In a preferred example, the utility model can be further configured as follows: the adjustment mechanism includes a bidirectional lead screw, a pair of adjustment blocks and four adjustment rods, the bidirectional lead screw is vertically arranged between the inner support block and the outer support block, a pair of the adjustment blocks are threadedly connected to the two ends of the bidirectional lead screw, the four adjustment rods are distributed in pairs on both sides of the adjustment block, one end of the adjustment rod is rotatably connected to the adjustment block, and the other end is rotatably connected to the support block or the outer support block.

[0015] In a preferred example, the utility model can be further configured as follows: silicone pads are provided at the ends of the inner support block and the outer support block that are away from each other.

[0016] In a preferred example, the utility model can be further configured as follows: one end of the bidirectional lead screw is provided with a spline, and the other end is provided with a keyway for the spline to be inserted.

DETAILED DESCRIPTION

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] Embodiment 1:

[0029] like Figure 1 As shown, a reinforcement device for a construction formwork of a curved wall or beam comprises a curved formwork 1, supporting square steels 2, wooden squares 3 and fixing parts 4.

[0030] like Figure 1 As shown, the arc-shaped formwork 1 includes inner and outer formworks arranged at intervals, forming a concrete pouring space in the middle, and forming an arc-shaped wall or beam after molding.

[0031] like Figure 2 , Figure 3 , Figure 4 As shown, the supporting square steel 2 is arranged outside the inner and outer templates to bend and arrange the arc template 1 according to the shape of the supporting square steel 2, and to support the arc template 1. Triangular notches 21 are arranged at intervals on the supporting square steel 2, and the outward end of the notch 21 is expanded to facilitate the control of the bending deformation of the supporting square steel 2.

[0032] like Figure 1 As shown, the wooden squares 3 are arranged at intervals between the arc-shaped template 1 and the supporting square steel 2 to achieve stable support between the two.

[0033] like Figure 1 As shown, the fixing part 4 is a tension bolt with a diameter of 14 mm, which passes through the arc formwork 1 and the supporting square steel 2, and connects the supporting square steels 2 on both sides inside and outside to fix the entire formwork system. If necessary, the formwork support system of the arc wall or beam can be fixed with basket bolts to prevent collapse.

[0034] When it is necessary to build a curved wall or beam, firstly, the thickness of the curved formwork 1, the position and spacing of the wooden squares 3, the spacing of the supporting square steels 2 and the spacing of the fixings 4 required to reinforce the curved reinforced concrete wall or beam are calculated using construction safety calculation software, and then the spacing of the notches 21 on the supporting square steels 2 is calculated using the spacing of the wooden squares 3 and the curvature of the curved structure.

[0035] When performing calculations, the size of the notch 21 can be designed through CAD software and BIM modeling. After the design is completed, workers are arranged to cut the notch 21 and bend the supporting square steel 2. After bending, it is necessary to further inspect whether the supporting square steel 2 can meet the reinforcement requirements of the curved reinforced concrete wall or beam.

[0036] After there are no problems, the notch 21 of the bent supporting square steel 2 is spot welded to better meet the tensile or compressive requirements of the formwork support system. After calculating the relevant parameters and processing the supporting square steel 2, the formwork support system is assembled at the construction site according to the construction specifications, so that the entire formwork system is economical, highly applicable, safe and reliable, and can meet the reinforcement requirements of various arc structures.

[0037] Embodiment 2:

[0038] like Figure 5 As shown, a reinforcement device for a construction formwork of a curved wall or beam, the wooden square 3 includes an inner support block 31, an outer support block 32 and an adjustment mechanism 5, the inner support block 31 abuts against the outer side of the curved formwork 1, the outer support block 32 abuts against the inner side of the supporting square steel 2, and the adjustment mechanism 5 is used to control the distance between the inner support block 31 and the outer support block 32.

[0039] like Figure 5 As shown, the adjustment mechanism includes a bidirectional lead screw 51 , a pair of adjustment blocks 52 and four adjustment rods 53 . The bidirectional lead screw 51 is vertically arranged between the inner support block 31 and the outer support block 32 . The pair of adjustment blocks 52 are threadedly connected to both ends of the bidirectional lead screw 51 .

[0040] like Figure 5 As shown, four adjustment rods 53 are distributed in pairs on both sides of the adjustment block 52 , wherein one end of the adjustment rod 53 is rotatably connected to the adjustment block 52 , and the other end is rotatably connected to the support block or the outer support block 32 .

[0041] When the thickness of the wooden planks 3 needs to be changed according to the construction requirements, the bidirectional screw 51 is controlled to rotate. At this time, the bidirectional screw 51 drives a pair of adjustment blocks 52 to move closer to or away from each other, thereby controlling the synchronous movement of the adjustment rods 53 on both sides to achieve the adjustment of the distance between the inner support block 31 and the outer support block 32, thereby meeting the use requirements of wooden planks 3 of different thicknesses and improving practicality. At the same time, the wooden planks 3 can be recycled and reused, which is also convenient for turnover and reduces construction costs.

[0042] like Figure 5 As shown, a silicone pad 33 is provided at one end of the inner support block 31 and the outer support block 32 which are away from each other, so as to reduce the pressure at the contact position and prevent pressure loss. At the same time, the contact area between the inner support block 31 and the outer support block 32 and the arc-shaped template 1 and the supporting square steel 2 can be increased at the arc position to ensure stable support and improve the stability of the template system.

[0043] like Figure 5 As shown, one end of the bidirectional lead screw 51 is provided with a spline 54, and the other end is provided with a keyway 55 for inserting the spline 54. The upper ends of the inner support block 31 and the outer support block 32 are provided with an insert block 34, and the lower ends are provided with a socket 35 for inserting the insert block 34.

[0044] When two or more layers of wooden planks 3 need to be laid, the upper and lower bidirectional lead screws 51 can be connected by plugging and fitting the splines 54 and the keyways 55 , and the upper and lower inner support blocks 31 and outer support blocks 32 can be connected by plugging and fitting the plug rods and the sockets 35 .

[0045] Therefore, when adjusting the spacing between the inner support block 31 and the outer support block 32, the spacing between all the inner support blocks 31 and the outer support blocks 32 can be adjusted by rotating any bidirectional lead screw 51, making the adjustment and assembly process more convenient. At the same time, the inner support blocks 31 and the outer support blocks 32 on the upper and lower sides are connected to each other, increasing the overall stability of the wooden square 3 and achieving stable support.

[0046] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
