Description

Technical Field

[0001] The utility model relates to the field of composite beams and slabs, in particular to a high-precision positioning frame for composite beams and slabs. Background Art

[0002] Composite beam-slab construction is a new building structure primarily composed of prefabricated concrete beams and slabs. Through a laminated construction method, it achieves lightweight yet high strength, improving construction efficiency and conserving materials. Composite beam-slabs offer excellent seismic performance and large spans, making them suitable for multi-story buildings and large spaces. Their simple construction process shortens construction timelines and reduces on-site complexity, making them an increasingly popular option in modern architecture.

[0003] After searching, the Chinese patent "A Prefabricated Composite Panel Support Frame" has the authorization announcement number "CN219281263U". This application provides a prefabricated composite panel support frame, which relates to the field of civil engineering technology. It includes a support frame body, a grounding composite plate for grounding and fixing, and a lateral support rod. The support frame body includes a mounting seat and a support rod, and a limiting slider is integrated at the bottom of the mounting seat. In this prefabricated composite panel support frame, the two groups of mounting seats are connected by a reinforcing telescopic rod for transverse reinforcement, and a grounding composite plate for grounding and fixing is provided at the bottom of the support frame body. By setting the first guide rail at the top of the grounding composite plate and the sliding connection between the limiting slider at the bottom of the mounting seat and the first guide rail, it is convenient for the user to adjust the spacing between the two groups of support rods for supporting the laminated panels, and the mounting seat can be conveniently fixed in different use positions by tightening the plug-in bolts on both sides of the limiting slider, so as to facilitate the adjustment of the lateral support position of the support frame body when the device is used to support laminated panels of different sizes.

[0004] Although the above-mentioned support frame can adjust the height and width of the entire device to support and position the composite beam slab, the fastening method after debugging is basically positioning through bolts, and there is a lack of movement consistency of the support points at both ends when adjusting the width. It is not only manpower-consuming and cumbersome to operate, but also causes inconsistent support points and affects the support of the composite beam slab.

[0005] Therefore, a high-precision positioning frame for composite beams and slabs is proposed to solve the above problems. Utility Model Content

The sliding seat can limit the movable shell to prevent the movable shell from displacement or slipping.

[0013] Preferably, the surfaces of the movable shell and the sliding rod are movably connected to the extrusion rod through a rotating shaft, and one end of the two extrusion rods is movably connected to a driving shell through a rotating shaft, the inner cavity of the driving shell is threadedly connected to a screw rod, and the end of the screw rod close to the movable shell is fixedly connected to a slide plate through a bearing seat, and the surface of the slide plate is slidably connected to the inner cavity of the limiting groove. Through the extrusion rod, the driving shell, the screw rod and the slide plate, the height of the sliding rod and its top connecting plate can be adjusted to increase the height of the composite beam plate so that it is aligned with the installation position.

[0014] Preferably, the surfaces of the sliding rod and the adjusting rod are respectively provided with scales, and the two scales are respectively provided on the front side and the side. By setting the scales, it is convenient for the staff to adjust the extension length of the sliding rod and the adjusting rod according to the specified value.

[0016] The beneficial effects of the utility model are:

[0017] 1. By arranging the adjustment shell, gear, adjustment rod and torsion block in the positioning support assembly, the staff can adjust the distance between the two movable shells more conveniently and quickly. At the same time, through the synchronous displacement method, the support position of the composite beam and slab of the whole device can be made more accurate, preventing the instability of the composite beam and slab caused by the misalignment of the support point;

[0018] 2. By arranging an extrusion rod, a drive housing and a screw rod between the surface of the movable shell and the sliding rod, it is easier for the staff to adjust the height of the connecting plate. At the same time, it can also avoid the slippage caused by the traditional method of fastening with bolts, thereby improving the supporting effect of the overall device and the positioning of the composite beam plate.

[0027] A positioning support assembly 3 is provided on the surface of the base plate 1;

[0028] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the positioning support assembly 3 includes a movable shell 301 arranged on the surface of the base plate 1, the inner cavity of the movable shell 301 is slidably connected to the sliding rod 303, the surface of the sliding rod 303 is provided with a connecting plate 304, and the surface of the movable shell 301 is provided with a limiting groove 312; the two movable shells 301 are fixedly connected to the adjusting rod 306 on opposite sides, and an adjusting shell 305 is provided between the surfaces of the two adjusting rods 306; the inner cavity of the adjusting shell 305 is provided with a gear 313, the top and bottom of the surface of the gear 313 are respectively meshed with the two adjusting rods 306, and the inner cavity of the gear 313 is fixedly connected to the torsion block 307 through a rotating shaft; the end of the movable shell 301 close to the base plate 1 is fixedly connected to the sliding seat 302, and the surface of the sliding seat 302 is slidably connected to the inner cavity of the first sliding groove 2; The surfaces of the movable shell 301 and the sliding rod 303 are movably connected to the extrusion rod 308 through a rotating shaft, and one end of the two extrusion rods 308 is movably connected to the driving shell 309 through a rotating shaft. The inner cavity of the driving shell 309 is threadedly connected to the screw rod 310, and the end of the screw rod 310 close to the movable shell 301 is fixedly connected to the slide plate 311 through a bearing seat, and the surface of the slide plate 311 is slidably connected to the inner cavity of the limiting groove 312; the surfaces of the sliding rod 303 and the adjusting rod 306 are respectively provided with scales 314, and the two scales 314 are respectively set on the front side and the side; the surface of the movable shell 301 is connected to the support rod 315 through a rotating shaft, and the end of the support rod 315 close to the bottom plate 1 is movably connected to the movable seat through a rotating shaft, and the surface of the movable seat is slidably connected to the inner cavity of the second sliding groove 4.

[0029] When the sliding rod 303 and the adjusting rod 306 are displaced, the staff can know the extended length of the sliding rod 303 and the adjusting rod 306 by observing the alignment position of the surface scale 314 and the edge of the movable shell 301 or the adjusting shell 305, which can improve the numerical accuracy of the support point position and height adjustment position of the composite beam and achieve a high-precision effect;
