Description

Technical Field

[0001] This utility model relates to the field of ultra-flat floor construction, and in particular to a combined steel formwork for ultra-flat floor construction. Background Technology

[0002] Currently, when constructing ultra-flat floors, it is necessary to use a level and spirit level to measure the elevation and levelness of the upper surface of the template to ensure that the upper surface of the template is flat and consistent with the elevation of the floor.

[0003] To meet the varying thickness requirements of different flooring construction projects, the applicant designed a height-adjustable formwork (CN218881508U) for ultra-flat flooring construction. This allows for horizontal raising and lowering of the side formwork simply by turning a pivot with a wrench, a simpler and more efficient method compared to the traditional method of adjusting multiple screws. However, during implementation, the applicant discovered that the need to cut the top plate of the channel steel along its length necessitates the creation of a specially designed L-shaped side formwork, resulting in higher manufacturing costs. Furthermore, the adjustment mechanism could be further optimized.

[0004] Application number CN201610349927.5 discloses a combined steel formwork for leveling ultra-flat ground, which has the advantages of simple structure and low manufacturing cost. However, during adjustment, it is necessary to use a wrench to adjust the upper and lower nuts at the connection between the bolt and the angle steel to eliminate the elevation error. The adjustment operation is troublesome and inefficient.

[0005] Therefore, how to conveniently adjust the formwork height while reducing the formwork manufacturing cost is a pressing issue. Consequently, a modular steel formwork for ultra-flat floor construction is proposed, which offers advantages such as low manufacturing cost and convenient, quick, and precise height adjustment.

[0027] Example 1

[0028] As attached Figure 1 To be continued Figure 5 As shown, this embodiment provides a combined steel formwork for ultra-flat floor construction, including channel steel 1, angle steel 2, thin steel plate 3, guide and positioning assembly 4, and lifting and adjusting assembly 5, wherein:

[0029] The bottom plate of the channel steel 1 can be fixed to the ground by means of nails or expansion bolts, and multiple guide and positioning components 4 are provided on its top plate.

[0030] The guide positioning assembly 4 includes columns 4.1 detachably installed on the top of the channel steel at equal intervals along its length, positioning plates 4.2 slidably mounted on the columns to limit the rising height of the angle steel, and locking bolts 4.3 for locking the position of the positioning plates. Preferably, in this embodiment, the bottom of the columns 4.1 is screwed to the top plate of the channel steel 1, and the columns 4.1 are provided with a sliding groove 4.1.1. One end of the positioning plate 4.2 is provided with a sleeve, and the inner wall of the sleeve is provided with a protrusion 4.2.1 that matches the sliding groove 4.1.1, so as to realize the sliding fit between the positioning plate and the columns.

[0031] The bottom plate of the angle steel 2 has through holes at each column 4.1, and guide sleeves 2.1 are installed in the through holes for sliding connection with the columns 4.1. The angle steel is limited by multiple columns, so that it can only move along the length of the columns. At the same time, multiple top rods 2.2 are provided at the bottom of the angle steel 2. The top rods 2.2 extend through the top plate of the channel steel 1 into the channel steel.

[0032] One end of the thin steel plate 3 is welded to the vertical plate of the angle steel 2, and the other end is tightly attached to the channel steel 1 to cover the gap between the angle steel and the channel steel and prevent grout leakage during pouring.

[0033] The lifting adjustment component 5 is located inside the channel steel 1 and acts on the top rod 2.2 to control the lifting and lowering of the angle steel. Preferably, in this embodiment, the lifting adjustment component 5 is a wedge-shaped lifting adjustment component. A roller 2.3 is rotatably mounted on the bottom of the top rod 2.2. The wedge-shaped lifting adjustment component lifts the top rod, thereby realizing the rise of the angle steel. The roller at the bottom of the top rod can reduce the friction between the top rod and the wedge-shaped lifting adjustment component.

[0034] Furthermore, the lifting and adjusting assembly 5 in this embodiment includes a slide rail 5.1, a slider 5.2, a fixing plate 5.3, an adjusting screw 5.4, and an adjusting handwheel 5.5. The slide rail 5.1 is fixedly installed on the base plate of the channel steel 1. The slider 5.2 is movably installed on the slide rail 5.1 and has multiple wedge blocks 5.2.1 corresponding to the top rod 2.2 for lifting the top rod. The fixing plate 5.3 is fixedly installed inside the channel steel 1. One end of the adjusting screw 5.4 is rotatably installed on one end of the slider 5.2 via a bearing, and the other end is threaded through the fixing plate 5.3 and connected to the adjusting handwheel 5.5. In this embodiment, the adjusting screw can be controlled to rotate forward by adjusting the handwheel, thereby causing the slider to move to the right along the slide rail, which in turn causes the top rod to lift the angle steel under the action of the wedge blocks, thus raising the angle steel. When the adjusting screw is controlled to rotate in reverse, the slider moves to the left along the slide rail, and the angle steel descends under its own weight.

[0035] Preferably, in this embodiment, a shoulder 2.2.1 is also provided on the top rod 2.2, and a spring 5.6 is also sleeved on the top rod 2.2 between the shoulder 2.2 and the top plate of the channel steel 1. When the control adjusting screw reverses, the slider moves to the left along the slide rail, and the angle steel is quickly reset by the spring.

[0036] In practice, the height of each positioning plate is first quickly adjusted according to the ground elevation, and then the angle steel is quickly lifted using the lifting and adjusting components so that the angle steel contacts the positioning plate. The operation is simple and efficient.

[0037] The modular steel formwork designed in this embodiment eliminates the need for cutting the top plate of the channel steel. Furthermore, the channel steel, angle steel, and thin steel plate are all readily available finished products of optional specifications. The structure of the guide positioning component and the lifting adjustment component is also simple, which can effectively reduce the manufacturing cost of the steel formwork.

[0038] Example 2

[0039] Based on Embodiment 1, the column 4.1 in this embodiment is provided with a scale (not shown in the figure), which can facilitate and quickly adjust the positioning plate to the set position.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
