Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an assemblable precast box girder formwork. Background Technology

[0002] Existing bridge box girder formwork is often a single unit. After using the formwork, dismantling the concrete is very troublesome. Moreover, after dismantling the concrete, the unused formwork needs to be transported away to facilitate other construction. However, since most bridge box girder formwork is a single unit, it not only occupies a lot of space during transportation but also cannot transport too many pieces of formwork.

[0003] During the patent application process, a search revealed a Chinese patent with patent number CN213382120U: an assemblable precast box girder template. Before use, the box girder template of the above patent was difficult to assemble because the upper and lower support plates were connected to the template body by plugging. Furthermore, the support area of ​​the telescopic rod on the upper support plate was too small, resulting in insufficient stability of the assembled box girder template. Therefore, improvements are needed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an assemblable precast box girder formwork, which solves the problems of inconvenient installation and insufficient stability.

[0005] This utility model also provides an assemblable precast box girder template, comprising: a vertical plate, an upper support plate hinged to the upper end of the vertical plate and a lower support plate hinged to the lower end, both the upper and lower support plates being flipped inward, a sliding groove provided on the side of the upper and lower support plates that are close to each other, a support block being slidably connected in the sliding groove, a groove provided on the opposite side of the two support blocks, a spherical connector being movably connected in the groove, a connecting pipe being fixedly connected to the spherical connector, a rotating block being rotatably connected to the connecting pipe, and a screw being slidably connected inside the connecting pipe on the side of the two rotating blocks that are close to each other, a limiting plate being fixedly connected to the rotating block and the limiting plate, a pin being slidably connected between the rotating block and the limiting plate, a thread being provided on the inner side of the rotating block, and a screw being threadedly connected to the screw, a snap-fit ​​block being fixedly connected to the other end of the screw, the snap-fit ​​block having a protrusion and a slot, and the snap-fit ​​blocks on the upper and lower sides being compatible.

[0006] According to the assembled precast box girder template, both the upper and lower support plates have two sliding grooves, which are symmetrically arranged.

[0007] According to the assembled precast box girder template, a limit strip is fixedly connected to one upper end of the upper support plate.

[0008] According to the assembled precast box girder template, a rubber pad is fixedly connected to the lower support plate located outside the chute.

[0009] According to the assembled precast box girder template, the protrusions and slots on the snap-fit ​​block are all fixedly connected with anti-slip pads.

[0010] According to the assembled precast box girder template, the size of the snap-fit ​​block is adapted to the sliding groove.

[0011] This utility model has the following beneficial effects:

[0012] In this invention, support plates are hinged to both ends of a vertical plate. The support plates contain a sliding groove, a support block, a connecting pipe, a screw, and a locking block. In use, the connecting pipe and screw in the sliding groove are flipped out, and the rotating blocks on the upper and lower connecting pipes are rotated to bring the locking blocks on both sides closer together until the protrusions and slots on the locking blocks on both sides are connected. Then, the pin and the limiting plate cooperate to fix the rotating block. The operation is convenient, no assembly is required, and the installation efficiency is improved.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-5 This utility model provides an assemblable precast box girder template, which includes a vertical plate 1. The upper end of the vertical plate 1 is hinged to an upper support plate 2, and the lower end is hinged to a lower support plate 3. The vertical plate 1 is L-shaped, which facilitates the storage of the upper support plate 2 and the lower support plate 3 and makes it easy to carry. A limiting strip 21 is fixedly connected to one end of the upper side of the upper support plate 2. The limiting strip 21 is used to position the template. Both the upper support plate 2 and the lower support plate 3 are flipped inward. A sliding groove 4 is provided on the side of the upper support plate 2 and the lower support plate 3 that are close to each other. There are two sliding grooves 4 on both the upper support plate 2 and the lower support plate 3, which are symmetrically arranged. A rubber pad 31 is fixedly connected to the lower support plate 3 located outside the sliding groove 4. Under the action of the rubber pad 31, the upper support plate 2 and the lower support plate 3 are prevented from colliding during storage.

[0024] A support block 5 is slidably connected within the groove 4. A groove 51 is provided on one side of each support block 5 opposite to the other. A spherical connector 61 is movably connected within the groove 51. A connecting pipe 6 is fixedly connected to the spherical connector 61. Under the action of the groove 51 and the spherical connector 61, the connecting pipe 6 can be flipped inwards and outwards, but cannot rotate. A rotating block 62 is rotatably connected to the connecting pipe 6, and a screw 7 is slidably connected inside it. The rotating block 62 is tubular. A limiting plate 63 is fixedly connected to the connecting pipe 6 on the side of the rotating blocks 62 that is close to each other. The limiting plate 63 has several pin holes. The rotating block 62 and the limiting plate 63 are connected... A pin 64 is slidably connected between the discs 63. Under the action of the pin 64 and the limiting disc 63, the rotating block 62 is easily fixed. The inner side of the rotating block 62 is provided with threads, and the threads are connected to the screw 7. The other end of the screw 7 is fixedly connected to the snap-fit ​​block 8. The size of the snap-fit ​​block 8 is adapted to the slide groove 4. The snap-fit ​​block 8 is provided with a protrusion 81 and a slot 82. The upper and lower snap-fit ​​blocks 8 are adapted to each other. The protrusion 81 and the slot 82 on the snap-fit ​​block 8 are fixedly connected with anti-slip pads. Under the action of the anti-slip pads, the friction between the snap-fit ​​blocks 8 on both sides is increased, the stability is improved, and the damage caused by the squeezing of the snap-fit ​​blocks 8 on both sides is avoided.

[0025] Working principle: When in use, first unfold the upper support plate 2 and the lower support plate 3, then flip the connecting pipe 6 and the screw 7 out from the slide groove 4, then slide the support block 5 to the outer end of the slide groove 4, and then rotate the rotating block 62 on the upper and lower connecting pipes 6 so that the two side locking blocks 8 come closer to each other until the protrusion 81 and the slot 82 on the two side locking blocks 8 are connected to each other. Then the pin 64 cooperates with the limiting plate 63 to fix the rotating block 62. No assembly is required, which improves the installation efficiency.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
