Description

Technical Field

[0001] The present application relates to the field of bridge construction, and in particular to a device for casting beam sleepers with adjustable formwork size. Background Art

[0002] Beam sleepers are commonly used auxiliary facilities in the construction of prefabricated box beams and prefabricated panels. They are often used as sleepers between beams. Since the prefabricated beams are 25m, 30m, and 31m in length during construction, and the cross-bridge dimensions of the bottom of the beams are different, the required length of the beam sleepers also needs to be adjusted accordingly. The conventional method is to use wooden formwork for construction, but after many uses, the formwork is prone to deformation, leakage, and poor appearance quality, and new formwork needs to be made. This method consumes more manpower and material resources, resulting in low utilization of wooden formwork and waste of resources.

[0003] The adjustable formwork in the prior art, such as an adjustable concrete lintel precast mold disclosed in authorization announcement No. CN219820070U, includes a partition and an open box mold, the box mold is a rectangular parallelepiped and is formed by a bottom plate, a first closing plate, a second closing plate and two side plates, the partition is arranged in the box mold and divides the inner cavity of the box mold into two parts, the partition can slide along the length direction of the box mold, and a fastener for fixing the partition is connected between the box mold and the partition. A mold is formed by enclosing a bottom plate, a first closing plate, a second closing plate and two side plates, and the size of the casting area of ​​the mold is adjusted by sliding the partition. Not only is the production simple and the construction of the prefabricated lintel is realized, but also the same prefabricated lintel mold can be used to cast lintels of different specifications, thereby reducing costs. Although the above scheme can be adjusted according to the size of the casting, the mold is an integral structure. After the casting is completed, the mold needs to be demolded. The demolding of the above scheme requires waiting for the casting to be completely solidified before demolding. Moreover, when demolding, it needs to be inverted and knocked to demold the workpiece and the mold, which makes demolding very inconvenient. Utility Model Content

[0004] The main purpose of the present application is to provide an adjustable formwork size device for pouring beam sleepers, which can not only be adjusted according to the size of the pouring parts, but also facilitates the demolding and installation of the mold.

[0005] In order to achieve the above-mentioned objectives, in a first aspect, the present application provides a device for casting an adjustable formwork size for a beam sleeper, comprising side formworks located on both sides, a first end formwork connected between the side formworks on both sides, and a second end formwork, positioning structures are respectively arranged between the two sides of the first end formwork and one end of the side formworks on both sides, and a tensioning structure is arranged between the other ends of the side formworks on both sides, the positioning structure comprises a guide positioning groove opened on the inner side of the side formworks on both sides or on both sides of the first end formwork, and a circular positioning protrusion fixedly arranged on both sides of the first end formwork or on the inner side of the side formworks on both sides and matching with the guide positioning groove, the guide positioning groove comprises a horizontal section with an entrance, and a vertical section connected with the horizontal section.

[0006] As a further improvement, the tensioning structure includes notches opened at the ends of the side formworks on both sides, mounting columns fixedly disposed in the notches, and connecting plates fixedly disposed on the mounting columns, and the connecting plates on both sides are connected by tension bolts.

[0007] A further improvement is that the first end template is a rectangular parallelepiped with a hollow structure, which is fixed by six panels.

[0008] As a further improvement, the second end template includes a first side plate and a second side plate, and a plurality of connecting columns are fixedly connected between the first side plate and the second side plate.

[0009] A further improvement is that the first side formwork and the second side formwork are made of channel steel.

[0010] A further improvement is that the first end template is welded from six steel plates.

[0011] A further improvement is that the first side plate and the second side plate are made of steel plates, the connecting column is made of steel bars or L-shaped channel steel, and the connecting column is welded and fixed to the first side plate and the second side plate.

[0012] A further improvement is that a scale is provided on the upper end surface of the first side template and / or the second side template.

[0013] The utility model provides a device for casting an adjustable formwork size for beam sleepers. Compared with the prior art, its beneficial effect is that when adjusting, only the position of the second end formwork needs to be adjusted, and the position of the first end formwork is relatively fixed. The positioning between the first end formwork and the side formwork is replaced by the original tension bolts through the cooperation of the guide positioning groove and the positioning protrusion. Moreover, when tension bolts are used on both sides, deformation will be caused by uneven force due to inconsistent tightening forces on both sides. In this solution, only tension bolts are used on one side, which is not only more convenient for demolding and installing the mold, but also does not cause uneven force, and the mold as a whole is not easy to deform. In addition, the entire mold adopts a rigid structure, which replaces the original wooden mold, and is not easy to have problems such as template deformation, slurry leakage, and poor appearance quality. Finally, through the set scale ruler, the position of the second end formwork can be accurately adjusted to ensure the dimensional accuracy of the cast part. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In addition, the term "plurality" shall mean two or more.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] like Figure 1-Figure 4 As shown, a device for casting a beam sleeper with an adjustable formwork size comprises side formworks 1 located on both sides, a first end formwork 2 connected between the side formworks 1 on both sides, and a second end formwork 3, positioning structures are respectively arranged between the two sides of the first end formwork 2 and one end of the side formworks 1 on both sides, and a tensioning structure is arranged between the other ends of the side formworks 1 on both sides, the positioning structure comprises a guide positioning groove 4 opened on the inner side of the side formworks 1 on both sides or on both sides of the first end formwork 2, and a circular positioning protrusion 5 fixedly arranged on both sides of the first end formwork 2 or on the inner side of the side formworks 1 on both sides and matched with the guide positioning groove 4, and the guide positioning groove 4 comprises a horizontal section with an entrance and a vertical section connected with the horizontal section.

[0027] Therefore, before the mold is used, it is pre-assembled. On a clean and flat road surface, the first end template 2 is first connected between the two side templates 1 through the positioning structure. When connecting, first align the circular positioning protrusion 5 horizontally with the entrance of the guide positioning groove 4, and then push it in horizontally, and then push it in vertically to complete the positioning. When pouring again, the expansion force of pouring expands outward, and the cooperation of the vertical section and the circular positioning protrusion 5 plays a good limiting role, and under the action of the first end template 2's own gravity, it is not easy to loosen. When removing the mold, you only need to first pull the first end template 2 upward and then withdraw it horizontally from the guide positioning groove 4, which is convenient to operate. In addition, as for the second end template 3, first adjust it to the desired position, and then tighten and fix it through the tensioning structure, clamp it from both sides through the two side templates 1, and during operation, the original need to operate the tension bolts 9 on both sides is reduced to only one side operating the tension bolts 9, which not only solves the problem of uneven force but also facilitates operation.

[0028] In this embodiment, preferably, the tensioning structure includes a notch 6 opened at the end of the side formwork 1 on both sides, a mounting column 7 fixedly arranged in the notch 6, and a connecting plate 8 fixedly arranged on the mounting column 7. The connecting plates 8 on both sides are connected by tension bolts 9. The notch 6, the mounting column 7 and the connecting plate 8 are provided to facilitate the installation and connection of the tension bolts 9. The mounting column 7 is welded in the notch 6 by steel bars, and the connecting plate 8 is welded to the steel bars by steel plates, which is convenient for processing and manufacturing.

[0029] Preferably, in the present embodiment, the first end template 2 is a rectangular parallelepiped with a hollow structure, which is fixed by six panels. In order to ensure the design of the positioning structure, the first end template 2 not only plays the role of an end template, but also plays a good limiting role. When operating the tension bolts 9, since there is a large flat contact surface between the first end template 2 and the side templates 1 on both sides, the tension bolts 9 are evenly stressed after being tightened, so that the entire mold will not have uneven stress and easy deformation.

[0030] In this embodiment, the second end formwork 3 includes a first side plate and a second side plate, and a plurality of connecting columns are fixedly connected between the first side plate and the second side plate. The second end formwork 3 only serves as an end formwork. Since it is close to the tension bolts 9, its force limiting capacity is limited. Therefore, its structure is simplified, which not only reduces the processing cost, but also reduces its weight, making it easier to operate and construct.

[0031] In order to prevent problems such as formwork deformation, leakage, and poor appearance quality, the first side formwork 1 and the second side formwork 1 are made of channel steel, the first end formwork 2 is welded from six steel plates, the first side panel and the second side panel are made of steel plates, the connecting column is made of steel bars or L-shaped channel steel, and the connecting column is welded and fixed to the first side panel and the second side panel.

[0032] Finally, in order to facilitate construction workers to adjust the size, a scale ruler 10 is provided on the upper end surface of the first side formwork 1 and / or the second side formwork 1.

[0033] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
