Description

Technical Field

[0001] The utility model relates to the field of box beam and T-beam templates, in particular to a prefabricated beam side template device with a transverse partition. Background Art

[0002] Prefabricated prestressed concrete small box beams and T-beams are common beam types. This structure has the advantages of fast construction speed, simple appearance, and good performance. It is particularly suitable for medium and small span bridges such as highways and urban elevated roads. Since small box beams and T-beams have structural characteristics such as thin webs and small width-to-span ratios, the installation of diaphragms can effectively increase the lateral stiffness of the cross section. Small box beams and T-beams are often equipped with oblique beams or orthogonal beams due to problems such as crossing rivers, roads, and straight lines, and the diaphragms are also oblique or orthogonal.

[0003] A Chinese patent document with the authorization announcement number CN219294268U discloses a side form device that can be used for oblique beams. An opening is provided on the side form template, and a diaphragm template is provided at the opening. An adjustment block can be selectively installed in the diaphragm template. By replacing the adjustment block, the diaphragm template can adapt to oblique beams of different angles. During casting, the beam body and the diaphragm can be directly cast without casting the diaphragm separately, which is conducive to reducing construction procedures and improving construction efficiency; the side form template is alternately driven by the transverse movement mechanism and the longitudinal movement mechanism to achieve transverse and longitudinal movement. When demoulding, the adjustment block remains stationary. When the side form template is driven to move transversely and demould by the transverse movement mechanism, the opening is larger than the width of the diaphragm. At this time, the side form template is driven to move longitudinally by the longitudinal movement mechanism until it does not interfere with the diaphragm and its protruding steel bars. This cycle can complete the demoulding of the side form template. After demoulding, the adjustment block can be removed without complicated template assembly operations. However, this technical solution also has certain defects:

[0004] 1) The opening has no support, and the diaphragm panel needs to be installed and supported later, which increases the workload. If a longer adjustment block is required, the concrete load surface will be larger and the support will be more difficult. If reliable support is not obtained, the bearing capacity may not meet the requirements. Therefore, the actual opening of this scheme is generally small, and the adjustment block is only installed on one side. When the length of the beam changes and the position of the diaphragm needs to be adjusted, since the diaphragm template and the side template are an integrated structure, the two need to be moved at the same time to achieve the purpose. Since the adjustment block can only be installed on one side, when the angle of the diaphragm changes, the template and the corresponding bracket at the diaphragm need to be replaced as a whole;

[0005] 2) When used for oblique beams, the diaphragm templates and adjustment blocks are all special-shaped templates, and the corresponding surfaces must be fitted together, which requires very high processing accuracy and is difficult to process. It is easy to have misalignment and joints. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a prefabricated beam side formwork device with a transverse partition which has a simple structure, is convenient for position adjustment and is conducive to reducing the workload of installation and disassembly.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0009] As a further improvement of the above technical solution: the cross section of the groove is a U-shaped structure or an L-shaped structure, and the opening of the L-shaped structure faces the end of the beam body.

[0010] As a further improvement of the above technical solution: a reinforcing rib is provided on the back side of the side mold template, and the reinforcing frame is connected to the reinforcing rib as a whole.

[0011] As a further improvement of the above technical solution: a plurality of hollow portions are provided on the side formwork for the protruding steel bars of the beam body to pass through.

[0012] As a further improvement of the above technical solution: the hollowed-out portion is a plurality of rows of grooves.

[0013] As a further improvement of the above technical solution: it also includes a baffle for preventing leakage of slurry, the baffle is arranged between the first adjusting block and the second adjusting block, and the baffle is provided with a through hole for the protruding steel bar to pass through.

[0014] As a further improvement of the above technical solution: the baffle is connected to the side mold template through a fastener.

[0015] As a further improvement of the above technical solution: the first adjusting block and the second adjusting block are both detachably connected to the side mold template.

[0016] As a further improvement of the above technical solution: the first adjustment block and the second adjustment block are both connected to the side mold template through fasteners.

[0017] As a further improvement of the above technical solution: the sides of the first adjustment block and the second adjustment block facing the beam body are flush with the working surface of the side mold template, and the first adjustment block and the second adjustment block are provided with a draft angle on the side close to the cross partition and / or the side away from the cross partition.

[0018] Compared with the prior art, the utility model has the advantages that: the precast beam side form device with diaphragm disclosed by the utility model, by opening a groove on the side form template and also providing a reinforcing frame on the back, ensures that the side form template can effectively bear the pressure brought by the concrete.

In addition, different adjustment blocks can be set on both sides of the groove according to the angle of the diaphragm to be cast, that is, when the angle of the diaphragm changes, there is no need to replace the template as a whole.

There is no need to move the position of the side form template as a whole, and the hoisting work of the large template is omitted, so that the use and construction are more convenient and the cost is lower.

[0031] Embodiment 1

[0032] Figures 1 to 5 An embodiment of the precast beam side form device with a transverse diaphragm of the utility model is shown. The precast beam side form device with a transverse diaphragm of this embodiment includes a side form template 1. In this embodiment, there are two sets of side form templates 1 arranged opposite to each other. A groove 11 is provided on the side of the side form template 1 facing the beam body 3, and a reinforcing frame 13 is provided on the back of the groove 11 (or the groove 11 is provided on the inner side of the side form template 1, and the reinforcing frame 13 is provided on the outer side of the side form template 1). A first adjustment block 21 is provided on the side of the groove 11 close to the end of the beam body 3, and a second adjustment block 22 is provided on the side close to the middle of the beam body 3 (see Figure 1, the first adjustment block 21 is arranged on the left side of the groove 11, and the second adjustment block 22 is arranged on the right side of the groove 11), and there is a gap between the first adjustment block 21 and the second adjustment block 22 to cast the diaphragm 31 of the beam body 3. In this embodiment, the reinforcing skeleton 13 is provided with a hollow portion 12. Preferably, the hollow portion 12 is a multi-row channel structure so that the protruding steel bars 32 can pass through, and can adapt to a variety of protruding steel bars 32 at different angles and positions. A reinforcing rib 14 is provided on the back of the side form template 1, or the reinforcing skeleton 13 corresponds to the groove 11 area, and the reinforcing rib 14 is arranged in other areas except the groove 11. The reinforcing skeleton 13 is connected to the reinforcing rib 14 as a whole, and cooperates with the side form back frame 6 to provide support, which is conducive to increasing the strength of the side form template 1, improving the strength of the groove 11 and the stability when pouring concrete. Among them, the reinforcing skeleton 13 can be made of reinforcing rib plates, channel steels or rectangular cross-section pipes, etc., all of which can strengthen the strength of the groove 11.

[0033] The precast beam side form device with a diaphragm in this embodiment ensures that the side form template 1 can effectively bear the pressure brought by the concrete by providing a groove 11 on the side form template 1 and a reinforcing frame 13 on the back. Compared with the existing side form template 1 with an opening, the problem of the bearing capacity not meeting the requirements due to the opening being too large is avoided, and the panel installation and disassembly process is also omitted. In addition, first adjusting blocks 21 and second adjusting blocks 22 of different angles or lengths can be set on both sides of the groove 11 according to the angle of the diaphragm 31 to be cast or the different positions of the diaphragm 31. When the length of the beam body 3 changes in a small range, generally only the positions of the diaphragms 31 at both ends of the beam body 3 need to be adjusted on site. By replacing the first adjusting blocks 21 and the second adjusting blocks 22 of different lengths, the position of the gap between the first adjusting blocks 21 and the second adjusting blocks 22 changes accordingly, and the position of the diaphragm 31 can be adjusted. Then, the position of the end mold can be adjusted accordingly to adapt to the change in the length of the beam body 3 without moving the position of the side mold template 1 as a whole. When the angle of the diaphragm 31 changes, only the first adjusting block 21 and the second adjusting block 22 with different bevel angles need to be replaced to adapt to the change in the angle of the diaphragm 31. There is no need to replace the template and bracket at the diaphragm as a whole, which saves the hoisting work of large templates, making it more convenient to use and construct, and lowering the cost.

[0034] Furthermore, in this embodiment, the cross section of the groove 11 is a U-shaped structure, and the cross sections of the first adjustment block 21 and the second adjustment block 22 are both right-angled trapezoidal structures, so that the straight edges of the first adjustment block 21 and the second adjustment block 22 can fit with the corresponding straight edges of the groove 11, and the side facing the beam body 3 is flush with the working surface of the side mold template 1 to avoid misalignment and seams. Correspondingly, the hypotenuse of the first adjustment block 21 and the second adjustment block 22 is adapted to the angle of the diaphragm 31. For diaphragms 31 of different angles, only the angle of the hypotenuse needs to be considered, which greatly reduces the processing difficulty of the side mold template 1, the first adjustment block 21 and the second adjustment block 22. Preferably, the first adjustment block 21 and the second adjustment block 22 are provided with a draft angle on the side close to the diaphragm 31 to facilitate demoulding. Of course, in other embodiments, the draft angle can also be set on the side of the first adjustment block 21 and the second adjustment block 22 away from the diaphragm 31, or the draft angle can be set on both sides.

[0035] Furthermore, in this embodiment, the first adjustment block 21 and the second adjustment block 22 are both detachably connected to the side mold template 1. Connecting the first adjustment block 21 and the second adjustment block 22 to the side mold template 1 is conducive to fixing the first adjustment block 21 and the second adjustment block 22 in the groove 11 to avoid displacement during pouring. When it is necessary to replace a different first adjustment block 21, second adjustment block 22 or adjust the position, the first adjustment block 21 and the second adjustment block 22 currently in use can be disassembled.

[0036] As a preferred embodiment, the first adjustment block 21 and the second adjustment block 22 are connected to the side formwork 1 by fasteners 4 (such as screws, bolts, etc.). The fasteners 4 are used to achieve a detachable connection, which has good connection reliability and is easy to disassemble.

[0037] Furthermore, in this embodiment, the precast beam side formwork device with a diaphragm also includes a baffle 5 for preventing slurry leakage. The side formwork template 1 is provided with a through hole (not shown in the figure) for the protruding steel bars 32 of the beam body 3 to pass through. The baffle 5 is located between the first adjustment block 21 and the second adjustment block 22. The baffle 5, the first adjustment block 21 and the second adjustment block 22 cooperate to form a forming cavity for the diaphragm 31. The baffle 5 is helpful in preventing slurry leakage from the hollow portion 12 of the side formwork template 1 during pouring, and can also increase the rigidity of the side formwork template 1. When the angle and position of the protruding steel bars 32 of the diaphragm 31 change, it is only necessary to open a through hole on the baffle 5 for the protruding steel bars 32 to pass through.

[0038] As a preferred embodiment, the baffle 5 is connected to the side mold template 1 through the fastener 4, which has good connection reliability and is easy to disassemble.

[0039] As a preferred embodiment, the first adjustment block 21 and the second adjustment block 22 are both formed by welding a plurality of plates. The first adjustment block 21 and the second adjustment block 22 of this structure are easy to process and adjust the bevel angle, and are light in weight, more convenient to install and disassemble, and also convenient for the fastener 4 to pass through.

[0040] Embodiment 2

[0041] Figure 6 Another embodiment of the precast beam side formwork device with a transverse partition of the utility model is shown. The precast beam side formwork device with a transverse partition of this embodiment has a structure that is basically the same as that of the first embodiment, except that:

[0042] In this embodiment, the cross section of the groove 11 is an L-shaped structure, and the opening of the L-shaped structure faces the end of the beam body 3. Accordingly, the first adjustment block 21 on one side of the groove 11 can be set to extend to the end of the beam body 3. When the length of the beam body 3 changes, the position of the first adjustment block 21 can be moved, and there is no need to replace the first adjustment block 21 as a whole, thereby reducing the construction workload.

[0043] Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the art can use the above disclosed technical content to make many possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention should fall within the scope of protection of the technical solution of the present invention.
