Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a support positioning device for a cast-in-place formwork of a building load-bearing column. Background Art
[0002] At present, a Chinese utility model with the announcement number CN204552089U discloses an inner support positioning device for a building beam template, comprising two positioning rods for inserting between two side templates of the beam template and respectively abutting against the inner side surfaces of the two side templates, and the two positioning rods are connected with a gripping rod and a cross bar for abutting against the two side templates to limit the insertion depth. The utility model has the advantages of repeated use, lightness and compactness, and easy operation, and can improve construction quality, reduce material waste, reduce labor, and reduce construction costs.
[0003] Although the existing formwork support and positioning device is easy to operate and can reduce material waste, there are still other problems in the use process, such as poor compaction effect. Although the formworks are only fixed at the intersection to maintain stability, gaps are likely to appear at the intersections, and the overall strength is difficult to guarantee. In addition, it does not have its own anti-shifting function. When concrete is poured into the formwork, the concrete will generate a strong impact force when entering, and the collision between the concrete and the formwork will easily cause the formwork to shift and float upward. Therefore, it is of low practicality. In order to solve the above-mentioned problems, we propose a support and positioning device for cast-in-place formwork for building load-bearing columns. Utility Model Content
[0004] The utility model aims to provide a support and positioning device for cast-in-situ formwork of a building load-bearing column, which solves the problem that the existing support and positioning device has a poor compacting effect and does not have a self-anti-shifting function.
[0005] The above technical objectives of the utility model are achieved through the following technical solutions:
[0006] A support and positioning device for cast-in-place formwork of a building load-bearing column comprises a lower limit frame, the top of which is respectively provided with two transverse formworks and two longitudinal formworks, an upper limit frame is arranged on the top of the lower limit frame, a first screw rod is welded to the top of each of the transverse formworks and the longitudinal formworks, the other end of the first screw rod penetrates and extends to the top of the upper limit frame, and a first fixing nut is threadedly connected to the surface of the first screw rod.
[0007] The above technical solution can achieve a good compaction effect, improve the strength between each template, ensure that the spacing between the templates remains constant, and have a simple structure.
[0008] The utility model is further configured as follows: a U-shaped plate is welded on one side of the transverse formwork and the longitudinal formwork, a through groove is opened at the bottom of the U-shaped plate, a second screw rod pre-buried in the ground is arranged inside the through groove, and a second fixing nut is threadedly connected to the surface of the second screw rod.
[0009] The above technical solution can ensure that the formwork has its own anti-movement function, thereby preventing the formwork from moving when concrete is poured. The operation is simple and the practicability is high.
[0010] The utility model is further configured as follows: guide rods are welded to the bottoms of the transverse template and the longitudinal template, and guide grooves used in conjunction with the guide rods are provided on the top of the lower limit frame.
[0011] By adopting the above technical solution, the transverse template and the longitudinal template can be guided by setting the guide rod and the guide groove, so that the transverse template and the longitudinal template can be quickly aligned with the lower limit frame when falling.
[0012] The utility model is further configured as follows: surfaces of the lower limit frame, the transverse template, the longitudinal template and the upper limit frame are all coated with anti-corrosion paint.
[0013] By adopting the above technical scheme and setting the anti-corrosion coating, the anti-corrosion effect of the surface of the lower limit frame, transverse template, longitudinal template and upper limit frame can be improved, thereby extending the service life of the lower limit frame, transverse template, longitudinal template and upper limit frame.
[0014] The utility model is further configured as follows: the first screw rod and the first fixing nut are both made of stainless steel.
[0015] By adopting the above technical solution, the first screw rod and the first fixing nut have the characteristics of high strength, low density and excellent corrosion resistance.
[0016] The utility model is further configured as follows: the width of the top of the U-shaped plate is greater than the width of the bottom.
[0017] By adopting the above technical solution, it is possible to prevent the bottom of the U-shaped plate from contacting and abutting against the lower limit frame.
[0018] The utility model is further configured as follows: the transverse template and the longitudinal template are both made of polypropylene granular material.
[0019] By adopting the above technical solution, the transverse formwork and the longitudinal formwork have the characteristics of light weight, high strength, wear resistance and corrosion resistance.
[0020] In summary, the utility model has the following beneficial effects:
[0021] 1. The utility model places the lower limit frame at the specified position first, then inserts the guide rods on the transverse template and the longitudinal template into the guide grooves, and picks up the upper limit frame after the transverse template and the longitudinal template are placed. When the upper limit frame is picked up and placed, the top end of the first screw rod is passed upward, and finally the first fixing nut is turned onto the first screw rod and tightened, which can achieve a good compacting effect, improve the strength between each template, and ensure that the spacing between the templates remains constant.
[0022] 2. The utility model pre-buries the second screw on the construction ground first. After the pre-buried second screw is completed, the number and position of the second screw will correspond to the through grooves in the U-shaped plate. After the U-shaped plate is lowered to the bottom, the bottom will fit the ground, and the top of the second screw will extend through the through groove to the inside of the U-shaped plate. Finally, the second fixing nut is taken out, turned onto the second screw and tightened. It can have its own anti-movement function, is simple and convenient to operate, and can prevent the template from moving when concrete is poured. It is highly practical.
