Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a concrete beam formwork reinforcement device. Background Technology

[0002] With continuous economic development, buildings are constantly being constructed. Concrete beams are one of the commonly used structural components in building engineering. They bear the important task of bearing and transferring the loads of floor slabs or roofs. The construction of concrete beams is crucial and directly affects the quality and performance of the building. Concrete beam formwork is usually made of plywood, which lacks sufficient strength and rigidity to effectively support and withstand the loads during concrete pouring, easily leading to bulging and deformation. Moreover, the use of steel-concrete composite beams is increasing. Traditional side formwork reinforcement of concrete beams requires inserting tie rods within the beam cross-section. However, because steel-concrete composite beams contain internal steel sections, it is difficult to drill tie rod holes on the side of the steel sections. Furthermore, drilling tie rod holes in the steel sections can affect the structural stress. Excessive drilling requires additional reinforcement measures, increasing workload and project costs. If the concrete beam formwork is not securely fixed, collapse accidents may occur during concrete pouring, endangering the lives of construction workers and rendering the poured concrete beam structure unusable, resulting in significant economic losses.

[0031] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Figure 1 This is a structural schematic diagram of the concrete beam formwork reinforcement device according to an embodiment of the present utility model;

[0033] Figure 2 This is a schematic diagram illustrating the application of the concrete beam formwork reinforcement device according to an embodiment of the present utility model. Figure 3 This is a top view of the application of the concrete beam formwork reinforcement device according to an embodiment of the present utility model;

[0034] like Figures 1-3 As shown in the figure, the concrete beam formwork reinforcement device proposed in this embodiment can be used to reinforce the left and right formwork of concrete beam casting, and can also be used to reinforce the left and right formwork of other structure casting.

[0035] This concrete beam formwork reinforcement device includes a first clamp 1 and a second clamp 2 connected by an adjusting screw 3. Both the first clamp 1 and the second clamp 2 are inverted L-shaped and are connected by the adjusting screw 3 to form a U-shaped rod. By adjusting the adjusting screw 3, the distance between the first clamp 1 and the second clamp 2 can be adapted to the distance between the outer sides of the left and right formwork 5, thereby clamping them on the outer sides of the left and right formwork 5.

[0036] To facilitate stable clamping on the outer sides of the formwork 5 on both sides of the concrete beam to be poured, the first clamp 1 may include a first connecting pipe 11, an end plate 13 with a central hole at the first end of the first connecting pipe 11, and a first clamping rod 12 vertically arranged on the side wall of the first end of the first connecting pipe 11, forming an inverted L-shaped right angle first clamp 1; the second clamp 2 includes a second connecting pipe 21 whose outer periphery is adapted to the inner periphery of the first connecting pipe 11, a sealing plate 23 at the first end of the second connecting pipe 21, an adjusting screw 3 welded to the middle of the sealing plate 23, and a second clamping rod 22 vertically arranged on the side wall of the second end of the second connecting pipe 21, forming an inverted L-shaped right angle second clamp 2.

[0037] The first end of the second connecting pipe 21 passes through the second end of the first connecting pipe 11, and the first clamping rod 12 and the second clamping rod 22 are in the same direction. The second connecting pipe 21 and the adjusting screw 3 are simultaneously inserted into the first connecting pipe 11. The adjusting screw 3 protrudes from the central hole of the end plate 13 of the first connecting pipe 11. The length of the second connecting pipe 21 inserted into the first connecting pipe 11 can be adjusted according to the distance between the outer sides of the left and right templates 5, so that the distance between the first clamping rod 12 and the second clamping rod 22 is close to the distance between the outer sides of the left and right templates 5. Then, it is clamped on the outer side of the left and right templates 5. The first connecting pipe 11 and the second connecting pipe 21 are horizontal above the left and right templates 5. Further adjustment is made so that the first clamping rod 12 and the second clamping rod 22 are respectively close to the outer side of the left and right templates 5. Finally, the part of the adjusting screw 3 that protrudes from the central hole is tightened with the nut 4. The support rods evenly arranged between the inner sides of the left and right templates 5 cooperate with the concrete beam template reinforcement device evenly arranged on the outer side of the left and right templates to clamp and position the left and right templates respectively.

[0038] The interlocking first connecting pipe 11 and the second connecting pipe 21 can be used to reinforce left and right templates with different spacing.

[0039] In one specific embodiment of this utility model, for stable insertion, both the first connecting pipe 11 and the second connecting pipe 21 are steel pipes with rectangular cross-sections. The square steel pipes facilitate alignment and insertion of the first connecting pipe 11 and the second connecting pipe 21. After insertion, the first clamping rod 12 and the second clamping rod 22 can be stably kept in the same direction, which is convenient for installation onto the outer mold.

[0040] In a specific embodiment of this utility model, the first clamping rod 12 and the second clamping rod 22 can be irregularly shaped channel steel of the same size. The irregularly shaped channel steel includes a middle plate with a lower end wider than the upper end and vertical plates and inclined plates respectively welded to both sides of the middle plate. The lower end of the first clamping rod 12 is welded to the side of the first connecting pipe 11, and the lower end of the second clamping rod 22 is welded to the side wall of the second connecting pipe 21. The vertical plates of the first clamping rod 12 and the vertical plates of the second clamping rod 22 are arranged opposite each other.

[0041] The first clamping rod 12 is welded to the first end of the first connecting pipe 11, and the second clamping rod 22 is welded to the second end of the second connecting pipe 21. The vertical plate forms a right angle with the first connecting pipe 11 / second connecting pipe 21. The vertical plates of the two clamping rods face each other. The first clamping rod 12, the first connecting pipe 11, the second connecting pipe 21, and the second clamping rod 22 form a right-angled U-shaped clamping component, which can be completely clamped to the outside of the left and right templates.

[0042] In one specific embodiment of this utility model, in order to ensure stable welding, the width of the vertical plate is equal to the width of the side wall of the first connecting pipe 11, and the wide end of the first clamping rod 12 / second clamping rod 22 can be stably and firmly welded to the first connecting pipe 11 / second connecting pipe 21.

[0043] In one specific embodiment of this utility model, the first connecting pipe 11 and the second connecting pipe 21 can have the same length, and the insertion of the first connecting pipe 11 and the second connecting pipe 21 can form various lengths, which can be applied to the reinforcement of various beam cross-section external molds.

[0044] In one specific embodiment of this utility model, the height of the first clamping rod 12 and the second clamping rod 22 can be no less than two-thirds of the height of the template 5, which is beneficial for the stable clamping of the template 5.

[0045] In one specific embodiment of this utility model, in order to stably connect the first connecting pipe 11 and the second connecting pipe 21, the screw can be an M12 screw, and an M12 nut 4 is tightened at the outer end of the screw. The thicker screw can stably support the sealing plate 23 connecting the second connecting pipe 21 and the end plate of the first connecting pipe.

[0046] In one specific embodiment of this utility model, the length of the screw is not less than the length of the first connecting tube 11, which ensures that the screw can be tightened when the first connecting tube 11 and the second connecting tube 21 are connected to form the longest possible length.

[0047] In one specific embodiment of this utility model, in order to prevent water ingress, a sealing plate is provided at the second end of the second connecting pipe 21. Each port of the second connecting pipe 21 and the first connecting pipe 11 is not completely open, which can reduce water ingress.

[0048] In a specific embodiment of this utility model, the number of concrete beam formwork reinforcement devices used can be determined according to the length of the formwork 5. The concrete beam formwork reinforcement devices can be evenly arranged on the outer side of both formworks, and concrete support rods are evenly supported between the inner sides of both formworks. Secondary timber squares are evenly supported on the outer side of the formwork along the height direction. The concrete support rods, timber squares and the concrete beam formwork reinforcement devices work together to clamp the two formworks 5.

[0049] The dimensions of each component of this utility model can be flexibly set according to the construction situation, and no specific limitation is made here.

[0050] The concrete beam formwork reinforcement device according to the present invention is described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the concrete beam formwork reinforcement device proposed in the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
