Abstract
Description
Technical Field
[0001] The utility model relates to the field of bridge reinforcement auxiliary devices, in particular to a U-shaped supporting forming die used for reinforcing a tensile zone of a T-shaped bridge with cement-based materials. Background Art
[0002] Highway bridges are an important part of road traffic. Currently, T-shaped bridges are widely used in highway bridges. However, under long-term service, the lower part of the beam of the T-shaped bridge (i.e., the tension zone) is prone to tensile cracks due to long-term tension. At present, the traditional repair and reinforcement methods are mostly to stick fiber fabric materials, such as carbon fiber cloth, on the lower part of the beam. This reinforcement method is simple and direct to construct, but there are also problems such as structural adhesives facing degradation and inability to effectively improve the bending stiffness of the beam. In addition, cement-based materials are a superior reinforcement material, but they have not been widely used in the field of bridge reinforcement. The reason is that there is no fixed platform for setting up the formwork, that is, the construction of cement-based materials for auxiliary reinforcement is difficult. At the same time, there is no targeted structure at the bottom of the T-shaped bridge for coordinated construction; based on this, this scheme designs a cement-based material support molding die for cement-based material reinforcement of the tension zone of the T-shaped bridge to solve the above problems. Summary of the invention
[0003] In view of this, the purpose of the utility model is to provide a U-shaped supporting forming mold for reinforcing the tension zone of a T-shaped bridge with cement-based materials, which has a simple structure, is flexible and convenient to implement, and has low operating difficulty.

[0007] A pair of sealing plates, which are arranged on two open sides of the U-shaped shell structure of the support plate and are detachably connected to the support plate to prevent side overflow when the molding cavity is filled with reinforcement materials;
[0008] Among them, the sealing plate is provided with an avoidance gap whose contour is adapted to the horseshoe-shaped structure of the reinforcement body. The upper part of the avoidance gap of the sealing plate is a slope structure, which is used to overlap and cooperate with the upper part of the horseshoe-shaped structure of the reinforcement body so that the support plate is relatively constrained and fixed on the reinforcement body.
[0009] As a possible implementation manner, further, the open sides of both sides of the support plate described in this solution are also provided with reinforcement plates extending outward, and the sealing plate is detachably connected to the reinforcement plates of the support plate.

[0013] There are multiple auxiliary support members, which penetrate into the U-shaped shell structure of the support plate from the closed sides of both sides of the support plate and are used to abut against the horseshoe-shaped structural surface of the reinforcement body, so that the support plate is auxiliary constrained and fixed on the reinforcement body.
[0014] As a preferred implementation option, preferably, the auxiliary support member of this solution includes:
[0015] A plurality of wedge-shaped pads are divided into two groups and arranged at intervals on both sides of the U-shaped shell structure of the support plate;

The multiple bolts are respectively inserted into the U-shaped shell structure of the support plate from the closed sides on both sides of the support plate and are threadedly connected with the corresponding wedge-shaped pads, so that the wedge-shaped pads are abutted against the surface of the reinforcement body.
[0017] As a preferred implementation option, preferably, the wedge-shaped pad described in this solution is made of wood or cement mortar.
[0018] As a preferred implementation option, preferably, the wedge-shaped pads described in this solution are arranged on the upper parts of both sides inside the U-shaped shell structure of the support plate.
[0019] As a preferred implementation option, preferably, the support plate and the sealing plate described in this solution are both made of steel, and the thickness thereof is 10 to 20 mm.
[0020] As a possible implementation mode, further, a T-beam diaphragm is provided at the lower portion of the T-shaped bridge in the present embodiment, and avoidance openings adapted to the T-beam diaphragm are provided on both closed sides of the support plate.

Since the sealing plate of the forming mold of the scheme has an avoidance gap, the avoidance gap can be used to assist in overlapping the supporting plate on the horseshoe-shaped reinforcement, which can greatly facilitate the fixation of the forming mold. In addition, the scheme further improves the stability of its installation by inserting a plurality of auxiliary support members on the supporting plate, so that when paying attention to the reinforcement material, it can avoid abnormal detachment problems such as the supporting plate slipping under force; and after the reinforcement material is solidified and formed, it is only necessary to disassemble the supporting plate and the sealing plate. The scheme has a simple structure, flexible and convenient implementation, and low operation difficulty. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is particularly noted that the following embodiments are only used to illustrate the present invention, but do not limit the scope of the present invention. Similarly, the following embodiments are only partial embodiments of the present invention rather than all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] like Figures 1 to 3 As shown in one of the embodiments, a U-shaped support forming mold for cement-based material reinforcement of the tension zone of a T-shaped bridge is provided. The upper two sides of the T-shaped bridge 9 are flanges 91, and the lower part is provided with a reinforcing body 93 of a horseshoe structure. The web 92 of the T-shaped bridge 9 is located above the reinforcing body 93. Figure 1 , Figure 2 As shown, the molding die comprises:
[0033] The support plate 3 is a U-shaped shell structure, the interior of which is used to penetrate and cooperate with the horseshoe-shaped structure of the reinforcement body 93, and a forming cavity for pouring reinforcement materials is formed between the interior of the U-shaped shell structure of the support plate 3 and the outer wall of the reinforcement body 93. In this solution, the U-shaped shell structure of the support plate is composed of a bottom plate 32 and side plates 31 arranged on both sides of the bottom plate 32, wherein the bottom plate 32 and the side plates 31 can be formed by bending or by welding and splicing;
[0034] The sealing plates 1 are a pair, and the sealing plates 1 are relatively arranged on the open sides of the U-shaped shell structure of the support plate 3 and are detachably connected to the support plate 3 to prevent side overflow when the molding cavity is poured with reinforcement materials. In order to facilitate assembly, in this solution, the sealing plates 1 are spliced by a pair of structurally symmetrical sub-plates 2.
[0035] In this solution, the inner contour dimension of the support plate 3 must be larger than the outer contour dimension of the horseshoe-shaped structure of the reinforcement body 93 of the T-shaped bridge. Therefore, when selecting the support plate 3, the inner contour dimension of the support plate 3 must be further determined based on the cement-based material reinforcement thickness requirements and the size specifications of the reinforcement body 93 in each reinforcement project.
[0036] In addition, the sealing plate 1 described in the present scheme is provided with an avoidance notch 11 whose contour is adapted to the horseshoe-shaped structure of the reinforcement body 93, and the upper part of the avoidance notch 11 of the sealing plate 1 is a slope structure, which is used to overlap and cooperate with the upper part of the horseshoe-shaped structure of the reinforcement body 93, so that the support plate 3 is relatively constrained and fixed on the reinforcement body 93, that is, after the sealing plate 1 is assembled on the support plate 3, the support plate 3 can be indirectly hung on the reinforcement body 93 through the slope structure on the upper avoidance notch 11 of the sealing plate 1, so as to facilitate the subsequent pouring of reinforcement materials.
[0037] In order to improve the structural rigidity of the support plate 3, in the present embodiment, the open sides of the support plate 3 are further provided with outwardly extending reinforcing plates 33. In the present embodiment, the reinforcing plates 33 can also be used as connecting plates, that is, the sealing plate 1 is detachably connected to the reinforcing plate 33 of the support plate 3, that is, the edge of the sub-plate 2 of the sealing plate 1 is detachably connected to the reinforcing plate 33.
[0038] As one of the better implementation options for the detachable connection between the closing plate 1 and the supporting plate 3, preferably, the closing plate 1 described in this scheme is detachably connected to the reinforcing plate 33 through a plurality of bolt and nut assemblies, and both the closing plate 1 and the reinforcing plate 33 are provided with mounting through holes for installing the bolt and nut assemblies, that is, the bolts 4 of the bolt and nut assembly pass through the mounting through holes on the reinforcing plate 33 and the closing plate 1 (specifically, the sub-plate 2 of the closing plate 1) in sequence, and then are locked by the nuts 5. In order to improve the locking stability, a gasket 6 may be further provided between the bolts and the nuts to improve the installation reliability.
[0039] Since the support plate 3 in this solution may be inconvenient to install due to its high dead weight, therefore, as a better implementation option, preferably, this solution also includes:
[0040] There are multiple auxiliary support members, which penetrate into the U-shaped shell structure of the support plate 3 from the closed sides of both sides of the support plate 3 (i.e., the side plates 31), and are used to abut against the horseshoe-shaped structural surface of the reinforcement body 93, so that the support plate 3 is auxiliary constrained and fixed on the reinforcement body 93; specifically, the auxiliary support members of this scheme include:
[0041] The wedge-shaped pads 8 are multiple and divided into two groups and arranged at intervals on both sides of the U-shaped shell structure of the support plate 3. In terms of material selection, the wedge-shaped pads 8 in this solution can be made of wood or cement mortar (when the cement-based reinforcement material filled into the molding cavity will immerse the wedge-shaped pads 8, wooden materials are not used);
[0042] There are multiple bolts 7 and they correspond one-to-one to the wedge-shaped pads 8. The multiple bolts 7 are respectively inserted into the U-shaped shell structure of the support plate 3 from the closed sides on both sides of the support plate 3 (i.e., the side plates 31) and are threadedly connected with the corresponding wedge-shaped pads 8, so that the wedge-shaped pads 8 are abutted against the surface of the reinforcement body 93.
[0043] The wedge-shaped pads 8 described in this solution are all arranged on the upper parts of both sides of the U-shaped shell structure of the support plate 3. At the same time, in order to prevent the bolts 7 from causing external force damage to the lower part of the T-shaped bridge 9, the threaded connection holes on the wedge-shaped pads 8 of this solution that cooperate with the bolts 7 are blind holes.
[0044] In terms of the material selection and specification thickness of the support plate 3 and the sealing plate 1, as a better implementation option, preferably, the support plate 3 and the sealing plate 1 described in this solution are both made of steel, and the thickness thereof is 10 to 20 mm.
[0045] exist Figure 1 , Figure 2 Based on the above, further combining Figure 3 , Figure 4 As shown, Figure 3 The schematic diagram shows that the forming mold of this scheme is installed on the reinforcement body 93 of the T-shaped bridge. It can be seen that after the device of this scheme is installed, the upper part of the support plate 3 has an opening for pouring reinforcement materials. The construction personnel can pour reinforcement materials (such as cement-based materials, which include cement mortar, ultra-high performance concrete, steel fiber concrete and other materials using cement as a binder) into it, and then remove the support plate 3 and the closing plate 1 after solidification. The installation of the U-shaped support can be completed.
[0046] Since one of the technical purposes of the device of this scheme is to facilitate installation, therefore, for some construction requirements of longer U-shaped supports (for example, for the situation where the crack distribution range in the tension zone of the T-beam is longer (>50cm), and the crack height (>40cm) extends into the web of the T-beam), the use of multiple support plates 3 for splicing can better adapt to the working conditions, improve the universality and flexibility of the device, and facilitate on-site installation. In actual operation, the length of the support plate 3 does not exceed 50cm each, and does not exceed 100cm after splicing.
[0047] Combination Figure 5 As shown, in this solution, for some cases where a longer U-shaped support is required, the above Figure 1 , Figure 2 In the structure shown, the number of pallets is increased to multiple, and the open sides of the multiple pallets are detachably connected to each other; in this case, a pair of sealing plates are detachably connected to the open sides of the U-shaped shell structure of the pallets located at both ends.
[0048] In addition, the present solution can also be achieved by raising the height of the support plate, for example, raising the side wall of the support plate to a height of 50 to 60 cm as required.
[0049] Combination Figure 6 , Figure 7 As shown, in this solution, when a T-beam diaphragm is also provided at the lower part of the T-shaped bridge, avoidance openings 311 adapted to the T-beam diaphragm are provided on both closed sides of the support plate.
[0050] The above descriptions are only some embodiments of the present invention, and do not limit the protection scope of the present invention. Any equivalent device or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present invention.
