TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a shearing wall formwork support structure. BACKGROUND

[0002] Before cast-in-place shearing wall is poured, a formwork needs to be set outside the reinforcement cage to limit the pouring shape of the concrete. The formwork is generally supported and fixed by a large number of inclined support rods and iron wires between the formworks. The support structure is complex, and it is difficult for workers to construct. SUMMARY

[0003] To solve or partially solve the problems in the related art, the present application provides a shearing wall formwork support structure, which aims to reduce the difficulty of formwork support and improve the working efficiency of shearing wall formwork support.

[0004] Therefore, the present application provides a shearing wall formwork support structure, which comprises a lateral support mechanism, a transverse pre-tightening mechanism and a wall formwork.

[0005] The wall formwork is arranged on both sides of the shearing wall pouring area.

[0006] The lateral support mechanism is arranged outside the wall formwork and comprises a support column, a bottom plate, an inclined support rod, a horizontal support rod and a wall formwork.

[0007] The lower end of the support column is hinged to one end of the bottom plate, the other end of the bottom plate is hinged to one end of the inclined support rod, the other end of the inclined support rod is movably connected to the upper part of the support column, and the support column, the bottom plate and the inclined support rod form a triangular structure.

[0008] The support column is provided with a horizontal support rod perpendicular thereto, the horizontal support rod is arranged in a vertical direction and abuts against the wall formwork.

[0009] The transverse pre-tightening mechanism comprises a PVC sleeve, a tensioning screw and a butterfly buckle. The tensioning screw passes through two wall formworks, the two ends of the tensioning screw are respectively threadedly connected with butterfly buckles, the butterfly buckles are located outside the wall formworks, the tensioning screw is sleeved with a PVC sleeve, and the PVC sleeve is located between the two wall formworks.

[0010] In some schemes, the bottom plate is provided with a through hole, and a positioning pin is inserted into the ground after passing through the through hole.

[0011] The outer end of the bottom plate is provided with a limiting column inserted into the ground.

[0012] In some schemes, the upper end of the inclined support rod is in abutment with the side surface of the support column, the side surface of the support column is screwed with locking bolts, the locking bolts are distributed along the vertical direction, and the lower end of the locking bolts is in abutment with the upper end of the inclined support rod.

[0013] In some schemes, the upper end of the inclined support rod is hinged with an L-shaped abutment block, and the upper end of the abutment block is in abutment with the locking bolt.

[0014] In some schemes, the splicing gap of the wall formwork is provided with a clearance hole matched with the size of the tensioning screw rod.

[0016] The horizontal support rod of the present application is in abutment with multiple wall formworks at the same time, and then the horizontal support rod is supported by the side support mechanism. After the fixed bottom plate is supported, the support column is rotated to stand up, which is convenient to install and effectively improves the labor intensity of the workers. At the same time, the two wall formworks are pulled tightly by the transverse pre-tightening mechanism, which effectively reduces the pressure on the side support mechanism during pouring, thereby improving the stability of the support.

DETAILED DESCRIPTION

[0024] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0025] like Figures 1-3 As shown, this application provides a shear wall formwork support structure, including a side support mechanism 1, a transverse pre-tightening mechanism 2, and a wall formwork 3. The wall formwork 3 is set on both sides of the shear wall pouring area to define the shape of the shear wall pouring, and can be made of wood, aluminum alloy steel plate, etc. The side support mechanism 1 is set on the outside of the wall formwork 3 (note: the side closer to the shear wall is defined as the outside, and the side farther from the shear wall is defined as the inside), effectively supporting the wall formwork 3 from the side to prevent the wall formwork 3 from collapsing during the shear wall pouring process. The transverse pre-tightening mechanism 2 is used to tighten the two wall formworks 3, so that the positions of the two wall formworks 3 mutually restrict each other, thereby reducing the pressure of the grout on the side support mechanism 1 during shear wall pouring. By supporting the wall formwork 3 simultaneously through the side support mechanism 1 and the transverse pre-tightening mechanism 2, the support is more stable and the support structure is more robust.

[0026] The side support mechanism 1 includes a support column 101, a base plate 102, diagonal braces 103, horizontal support rods 104, and a wall template 3. The lower end of the support column 101 is hinged to one end of the base plate 102, and the other end of the base plate 102 is hinged to one end of the diagonal brace 103. The other end of the diagonal brace 103 is movably connected to the upper part of the support column 101. The support column 101, the base plate 102, and the diagonal brace 103 form a triangular structure. The support column 101 is provided with horizontal support rods 104 that are perpendicular to it. The horizontal support rods 104 are spaced apart in the vertical direction and abut against the wall template 3.

[0027] In use, the horizontal support rod 104 is installed on the wall formwork 3, the base plate 102 is fixed on the ground, and then the support column 101 is rotated to be parallel to the wall formwork 3, at this time, the inner side of the horizontal support rod 104 is just abutted on the horizontal support rod 104, thereby forming stable support to the wall formwork 3. It is conceivable that the workers can set multiple triangular structures composed of the support column 101, the base plate 102 and the inclined support rod 103 along the length direction of the shear wall at intervals according to the length of the shear wall, and the horizontal support rod 104 is supported by the multiple triangular structures at the same time, thereby further improving the support stability of the horizontal support rod 104. Preferably, the horizontal support rod 104 is arranged at intervals in the vertical direction, and the wall formwork 3 is supported by multiple points, which is beneficial to improve the support stability of the wall formwork 3.

[0028] The transverse pre-tightening mechanism 2 comprises a PVC sleeve 201, a tensioning screw 202 and a butterfly buckle 203. The tensioning screw 202 passes through two wall formworks 3, and the two ends of the tensioning screw 202 are respectively threadedly connected with the butterfly buckles 203. The butterfly buckles 203 are located outside the wall formworks 3, and the PVC sleeve 201 is arranged on the tensioning screw 202 and located between the two wall formworks 3. The butterfly buckle 203 adopts a “mountain”-shaped butterfly buckle 203. In use, the butterfly buckles 203 are tightened to abut the two ends of the butterfly buckles 203 with the wall formworks 3, thereby tightening the two wall formworks 3, and effectively reducing the pressure of the slurry on the lateral support mechanism 1 during pouring of the shear wall. The PVC sleeve 201 facilitates the removal of the shear wall after pouring, and enables the tensioning screw 202 to be reused.

[0029] Preferably, the transverse pre-tightening mechanisms 2 are uniformly and intermittently arranged at the gaps of the wall formworks 3, thereby limiting the wall formworks 3 at multiple points, effectively reducing the stress of the wall formworks 3, and thereby improving the service life of the wall formworks 3.

[0030] In some specific embodiments, the support column 101 is provided with a clamping groove matched with the horizontal support rod 104, and the horizontal support rod 104 is clamped in the clamping groove. In this way, when the lateral support mechanism 1 is built, the horizontal support rod 104 can be first fixed on the support column 101, and then the support column 101 is erected, which is beneficial to improve the installation convenience of the lateral support mechanism 1.

[0031] In some specific embodiments, the base plate 102 is provided with a through hole, and the positioning pin 4 is inserted into the ground after passing through the through hole. The outer end of the base plate 102 is provided with a limiting column 5 inserted into the ground. The positioning pin 4 and the limiting column 5 enable the base plate 102 to be stably fixed on the ground, thereby effectively ensuring the stability of the lateral support mechanism 1.

[0032] In some embodiments, the upper end of the inclined support rod 103 is in abutment with the side surface of the support column 101, and the side surface of the support column 101 is provided with a protruding connecting portion, and a locking bolt 105 is threadedly connected to the connecting portion, the locking bolt 105 is distributed along the vertical direction, and the lower end of the locking bolt 105 is in abutment with the upper end of the inclined support rod 103, so that the upper end of the inclined support rod 103 is driven to move downward by rotating the locking bolt 105, so as to adjust the inclination of the inclined support rod 103, and further adjust the angle of the support column 101.

[0033] In some embodiments, the upper end of the inclined support rod 103 is hingedly connected with an L-shaped abutment block 106, and the upper end of the abutment block 106 is in abutment with the locking bolt 105.

[0034] In some embodiments, the spliced gap of the wall formwork 3 is provided with a clearance hole matched with the size of the tension screw rod 202, and the tension screw rod 202 is installed to pass through the clearance hole, which is conducive to reducing the size of the gap between adjacent wall formworks 3, thereby improving the surface quality of the cast shear wall.

[0035] The above has described the embodiments of the present application, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles, practical application, or improvement of the technology in the market of the embodiments, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
