Abstract
Description
Technical Field
[0001] The invention relates to the field of building construction, and in particular to a steel column shear wall formwork supporting structure. Background Art
[0002] In the field of building construction, it is necessary to support the formwork of the shear wall formwork containing the steel column position, especially for the formwork construction of the rectangular steel column shear wall with stiffening plate. The existing technical construction scheme is as follows Figure 1 and Figure 2 As shown: a stiffening plate 2 extending outward is fixed on a rectangular shear wall steel column 1, and the supporting structure adopts a formwork 3 + secondary beam 4 + main beam 5 + tension screw 6. The formwork 6 is fixed on the outside of the stiffening plate 2, and several secondary beams 4 are fixed between the outsides of the formwork 6. Several main beams 5 are fixed on the outsides of the secondary beams 4. The main beams 5 are fixed by multiple tension screws 6 to tie the shear wall formwork support.
[0003] At the same time, the tension screw rod 6 located near the end of the shear wall steel column is set close to the edge of the steel column stiffening plate 2. This is to ensure that the rigidity of the shear wall formwork support cantilever section is sufficient, and the length of the support cantilever section cannot be too long. Therefore, the tension screw rod 6 near the end of the steel column must be set near the edge of the steel column stiffening plate 2, otherwise the insufficient rigidity caused by the excessive length of the support cantilever section will directly lead to the problem of slurry leakage.
[0004] The existing construction scheme always has the following problems: the reserved vibration space in the area of the steel column stiffening plate 2 is small, which is prone to uneven vibration and missed vibration, resulting in loose concrete inside, loose surface layer, defects, exposed reinforcement or cracks, etc., and the construction quality is difficult to guarantee. The formwork construction of steel column shear walls with stiffening plates has always been troubled by this problem. Summary of the invention
[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a steel column shear wall formwork support structure, which can solve the problem of poor construction quality of the steel column stiffening plate area existing in the current steel column shear wall formwork construction.
[0006] The present invention is achieved through the following technical solutions:
[0007] A steel column shear wall formwork support structure, comprising:
[0008] Steel column section, including: shear wall steel column and stiffening plates; several stiffening plates extending towards the shear wall formwork are fixedly connected to the shear wall steel column; main body section, including: shear wall formwork, secondary steel pipe beams for shear wall formwork support, main steel pipe beams for shear wall formwork support, and tie bolts for shear wall formwork support; the shear wall formwork is provided on the outer sides of the outermost two stiffening plates, the secondary steel pipe beams for shear wall formwork support are fixed on the outer side of the shear wall formwork, the main steel pipe beams for shear wall formwork support are fixed on the outer side of the secondary steel pipe beams for shear wall formwork support, and both ends of the tie bolts for shear wall formwork support are fastened to the two main steel pipe beams for shear wall formwork support to tie and support the shear wall formwork; reinforcement section, including: stiffening plate bolts, end vertical steel pipe beams, and bending connectors; the stiffening plate bolts pass through the main steel pipe beams for shear wall formwork support and the stiffening plates, and the two fastening ends of the stiffening plate bolts press the end vertical steel pipe beams against the main steel pipe beams for shear wall formwork support; the bending connector has two connecting surfaces, and the two connecting surfaces are respectively fixedly connected to the stiffening plate and the stiffening plate bolts.
[0009] Further, the reinforcement section further includes: pressing blocks; the pressing blocks are arranged on the stiffening plate bolts, the inner sides of the pressing blocks abut against the end vertical steel pipe beams, and the nuts of the stiffening plate bolts are screwed tightly on the outer sides of the pressing blocks to press the end vertical steel pipe beams against the main steel pipe beams for shear wall formwork support.
[0010] Further, the end vertical steel pipe beam is: a double steel pipe structure; the double steel pipes are respectively arranged on both sides of the stiffening plate bolts; the pressing blocks press on both steel pipes simultaneously.
[0011] Further, the bending connector is: a 90-degree bent round steel, having two mutually perpendicular connecting surfaces; the two connecting surfaces are respectively fixed on the outer side surface of the stiffening plate and the outer circumference of the stiffening plate bolts.
[0012] Further, the main steel pipe beams for shear wall formwork support are a horizontally arranged double steel pipe structure; the main steel pipe beams for shear wall formwork support are perpendicular to the arrangement direction of the secondary steel pipe beams for shear wall formwork support; the main steel pipe beams for shear wall formwork support are perpendicular to the arrangement direction of the end vertical steel pipe beams.
[0013] Further, the nuts of the tie bolts for shear wall formwork support press on both steel pipes of the main steel pipe beams for shear wall formwork support simultaneously.
[0014] Further, the secondary steel pipe beams for shear wall formwork support are a vertically arranged single steel pipe structure.
[0015] Further, the stiffening plate and the stiffening plate bolts are fixedly connected by welding.
[0016] Further, the bending connector and the outer side surface of the stiffening plate are fixedly connected by welding.
[0017] Furthermore, the bent connecting piece is fixedly welded to the outer peripheral surface of the stiffening plate screw.
[0018] Compared with the prior art, the beneficial effects that the present invention can achieve are as follows:
[0019] The connection stability of the end structure of the shear wall formwork is enhanced by the stiffening plate screw and the bent connecting piece welded on the stiffening plate screw. Since the stability of the end structure of the shear wall formwork is ensured, the distance between the tie bolts of the main body section and the stiffening plate can be increased, that is, the supporting cantilever section can be lengthened, and the concrete vibration space in the stiffening plate area at the end of the shear wall can be greatly increased, which is convenient for the concrete to be vibrated sufficiently, thereby effectively improving the concrete construction quality. In addition, by adding an end vertical steel pipe beam at the end of the shear wall formwork, the original main steel pipe beam for the shear wall formwork is used as the secondary beam, and the end vertical steel pipe beam is used as the main beam. After the stiffening plate screw is locked, the main steel pipe beam for the shear wall formwork will have a slight tendency to deform inward towards the wall, further locking the edge formwork support member, increasing the stiffness of the end structure of the shear wall formwork, and ensuring the concrete construction quality.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] Referring to Figures 3 - 5 , the present invention discloses a steel column shear wall formwork support structure, including:
[0031] A steel column section, including: a shear wall steel column 10 and stiffening plates 20; a plurality of stiffening plates 20 are fixedly connected to the shear wall steel column 10, and their installation direction extends towards the shear wall formwork 30.
[0032] A main body section, including: a shear wall formwork 30, a secondary shear wall formwork support steel pipe beam 40, a main shear wall formwork support steel pipe beam 50, and a shear wall formwork tie rod 60. Among them, the shear wall formwork 30 is provided on the outer sides of the two outermost stiffening plates 20, the secondary shear wall formwork support steel pipe beam 40 is fixed on the outer side of the shear wall formwork 30, the main shear wall formwork support steel pipe beam 50 is fixed on the outer side of the secondary shear wall formwork support steel pipe beam 40, and both ends of the shear wall formwork tie rod 60 are fastened to the two main shear wall formwork support steel pipe beams 50 to tie and support the shear wall formwork 30, that is, to tie and fasten the shear wall formwork 30, the secondary shear wall formwork support steel pipe beam 40, and the main shear wall formwork support steel pipe beam 50 together.
[0033] Reinforcement section, comprising: stiffening plate screw 70, end vertical steel pipe beam 80 and bent connecting piece 90; the stiffening plate screw 70 passes through the main formwork steel pipe beam 50 of the shear wall and the stiffening plate 20, and the two fastening ends of the stiffening plate screw 70 press the end vertical steel pipe beam 80 against the main formwork steel pipe beam 50 of the shear wall, causing a slight inward deformation of the end vertical steel pipe beam 80; the bent connecting piece 90 has two connecting surfaces, which are respectively fixedly connected to the stiffening plate 20 and the stiffening plate screw 70.
[0034] In the past, the structure on one side of the shear wall formwork 30 was tied by tie bolts. In order to avoid insufficient stiffness caused by too long support cantilever section, the interval between the tie bolts and the stiffening plate 20 must be small. In the present invention, the connection stability of the end structure of the shear wall formwork 30 is enhanced by the stiffening plate screw 70 and welding the bent connecting piece 90 on the stiffening plate screw 70 (the bent connecting piece 90 is also fixed to the stiffening plate 20). Since the stability of the end structure of the shear wall formwork 30 is ensured, the distance between the main body section tie bolts and the stiffening plate 20 can be increased, that is, the support cantilever section can be lengthened, and the concrete vibration space in the area of the stiffening plate 20 at the end of the shear wall can be greatly increased, facilitating full vibration of the concrete, thereby effectively improving the concrete construction quality. At the same time, by adding an end vertical steel pipe beam 80 at the end of the shear wall formwork 30, taking the original main formwork steel pipe beam 50 of the shear wall as the secondary beam and the end vertical steel pipe beam 80 as the main beam, after tightening the stiffening plate screw 70, the main formwork steel pipe beam 50 of the shear wall will have a tendency to deform slightly inward towards the wall, further tightening the edge formwork support member, increasing the stiffness of the end structure of the shear wall formwork 30, and ensuring the concrete construction quality.
[0035] Preferably, the reinforcement section further includes a pressing block 100. The pressing block 100 is arranged on the stiffening plate screw 70, the inner side of the pressing block 100 abuts against the end vertical steel pipe beam 80, and the nut of the stiffening plate screw 70 is tightened on the outer side of the pressing block 100, thereby pressing the end vertical steel pipe beam 80 against the main formwork steel pipe beam 50 of the shear wall. The pressing block 100 serves to apply the nut locking force to the end vertical steel pipe beam 80.
[0036] Preferably, the end vertical steel pipe beam 80 is specifically a double-steel pipe structure, and the double steel pipes are respectively arranged on both sides of the stiffening plate screw 70, and the pressing block 100 presses on both steel pipes at the same time.
[0037] Preferably, the bent connecting piece 90 is specifically a 90-degree bent round steel, which has two mutually perpendicular connecting surfaces, and the two connecting surfaces are respectively fixed on the outer side surface of the stiffening plate 20 and the outer circumference of the stiffening plate screw 70.
[0038] Preferably, the main steel pipe beam 50 for formwork of shear wall is specifically a double-steel-pipe structure arranged horizontally; the main steel pipe beam 50 for formwork of shear wall is perpendicular to the arrangement direction of the secondary steel pipe beam 40 for formwork of shear wall, and the main steel pipe beam 50 for formwork of shear wall is perpendicular to the arrangement direction of the end vertical steel pipe beam 80.
[0039] Preferably, the nuts of the tension bolts 60 for formwork of shear wall are simultaneously pressed against the two steel pipes of the main steel pipe beam 50 for formwork of shear wall.
[0040] Preferably, the secondary steel pipe beam 40 for formwork of shear wall is a single-steel-pipe structure arranged vertically.
[0041] Preferably, the stiffening plate 20 and the stiffening plate bolt 70 are fixed by welding.
[0042] Preferably, the outer side of the bending connector 90 and the stiffening plate 20 are fixed by welding.
[0043] Preferably, the outer peripheral surfaces of the bending connector 90 and the stiffening plate bolt 70 are fixed by welding.
