Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated plate supports, and in particular relates to a bridge prefabricated plate supporting device. Background Art

[0002] Bridge precast panels refer to the bridge panels that are prefabricated in factories or precast yards during bridge construction and then transported to the site for installation. There are many types of bridge precast panels, such as prestressed concrete hollow panels, prestressed concrete solid panels, prestressed concrete T-beams, etc. Different types and specifications of precast panels have different usage methods and precautions.

[0003] Problems with existing technologies:

[0004] Precast slab support refers to the support system used in the construction of precast slabs to ensure the stability and safety of the precast slabs. The amount of scaffolding used in the precast slab support system is much lower than that of cast-in-place structures. According to different construction conditions and requirements, the way of precast slab support will also be different. For example, the support system used in the construction of precast slabs of bridges to ensure the stability and safety of precast slabs needs to be carried out on the piers to ensure the stability and load-bearing capacity of the precast slabs. Among them, the most important thing is that the precast slabs also have the function of stacking in the installation sequence during the lifting process. However, for some existing precast slab supports, when workers guide the precast slabs to dock with the piers on the base, the bottom of the support plate completely supports the precast slabs, which makes the line of sight blocked during the stacking and installation with the piers. In addition, the precast slab body 1 is unstable during the lifting process. Utility Model Content

[0005] The purpose of the utility model is to provide a bridge precast slab support device, which can provide a relatively stable lifting environment and will not produce a large swing amplitude. Workers can identify the position of the precast holes at the bottom of the precast slab body 1 by observation and issue corresponding instructions to install the precast slab body 1 accordingly with the bridge piers, so that it can be quickly stacked in sequence with the bridge piers.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A bridge precast panel support device comprises a precast panel body, wherein a movable gantry is provided on the top of the precast panel body, a support assembly for supporting the precast panel body is provided on the bottom of the precast panel body, and the movable gantry hoisting support assembly moves with the precast panel body.

[0008] The support assembly includes a main beam and a secondary beam relatively arranged on both sides of the prefabricated panel body. A bottom support is provided at the relative position of the main beam and the secondary beam. The bottom support holds the panel body, and the two sides of the bottom support are adapted to extend from the outside of the prefabricated panel body to form protective side arms.

[0009] Support feet are symmetrically arranged on the side walls opposite to the main beam and the auxiliary beam, and rolling pulleys are arranged at the bottom of the support feet. Steel ropes are arranged at positions corresponding to the pulleys on both sides of the movable gantry, and the steel ropes lift the support assembly through the pulleys.

[0010] A support foot is provided at the bottom of the main beam and the auxiliary beam and between the support feet, and the bottom of the support foot protrudes from the bottom of the support foot.

[0011] The positions where the support legs are fixed to the main beam and the auxiliary beam are all provided with ribs, and are reinforced by the ribs.

[0012] A support plate is arranged on a side of the main beam opposite to the supporting foot, and a baffle is arranged on a side of the secondary beam opposite to the support plate.

[0013] The support plate is located at the bottom of the baffle plate and is in contact with the baffle plate.

[0014] The technical effects achieved by the utility model are:

[0015] The utility model has a bottom support that supports the bottom of the precast panel body to prevent the ground of the precast panel body from being worn during lifting, and the outer side of the bottom support extends to form a protective side arm that can better protect the side wings of the precast panel body, has a relatively stable lifting environment, and will not produce a large swing amplitude, and in the lifting process, the precast panel body is always between the main beam and the auxiliary beam, thereby improving the safety and efficiency of the precast panel body during the lifting construction process, and when the precast panel body is stacked, the support legs first contact the pads, and the precast panel body is in a suspended state, and the workers can identify the position of the precast holes at the bottom of the precast panel body by observation, and issue corresponding instructions to install the precast panel body and the bridge pier accordingly, so that it can be quickly stacked in sequence with the bridge pier.

[0024] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0025] like Figure 1-2 As shown, a bridge precast panel supporting device comprises a precast panel body 1, a movable gantry 2 is provided on the top of the precast panel body 1, a supporting assembly 3 for supporting the precast panel body 1 is provided on the bottom of the precast panel body 1, the movable gantry 2 hoists the supporting assembly 3 and moves with the precast panel body 1, the supporting assembly 3 comprises a main beam 301 and a secondary beam 302 which are relatively arranged on both sides of the precast panel body 1, a bottom support 307 is provided at the relative position of the main beam 301 and the secondary beam 302, the bottom support 307 holds the panel body 1, and the two sides of the bottom support 307 are adapted to extend from the outside of the precast panel body 1 to form protective side arms.

[0026] Furthermore, the bottom support 307 supports the bottom of the precast panel body 1 to prevent the ground of the precast panel body 1 from being worn during the lifting process, and the outer side of the bottom support 307 extends to form a protective side arm that can better protect the side wings of the precast panel body 1. This special shape design can not only provide better protection for the precast panel body 1, but also make it located between two opposite main beams 301 and secondary beams 302 during the lifting process, so as to have a relatively stable lifting environment and will not produce a large swing amplitude.

[0027] Refer to the attached Figure 2-3 Support legs 303 are symmetrically arranged on the side walls opposite to the main beam 301 and the auxiliary beam 302, and a rolling pulley 304 is arranged at the bottom of the support legs 303. Steel ropes 4 are arranged at the positions corresponding to the pulleys 304 on both sides of the mobile gantry 2. The steel ropes 4 lift the support assembly 3 through the pulleys 304. Support legs 305 are arranged at the bottom of the main beam 301 and the auxiliary beam 302 and between the support legs 303, and the bottom of the support legs 305 protrudes from the bottom of the support legs 303.

[0028] Furthermore, during the lifting process, the precast panel body 1 is always between the main beam 301 and the secondary beam 302, which improves the safety and efficiency of the precast panel body 1 during the lifting construction process, and the bottom of the support legs 305 on the main beam 301 and the secondary beam 302 protrudes from the bottom of the support legs 303, so that when the precast panel body 1 is stacked, the support legs 305 first contact the pads, and the precast panel body 1 is in a suspended state. At this time, the workers can identify the position of the precast holes at the bottom of the precast panel body 1 by observation, and issue corresponding instructions to install the precast panel body 1 accordingly with the bridge piers, so that it can be quickly stacked in sequence with the bridge piers.

[0029] Furthermore, ribs 306 are provided at the positions where the support legs 305 are fixed to the main beam 301 and the auxiliary beam 302 , and are reinforced by the ribs 306 .

[0030] Refer to the attached Figure 3-4 A support plate 309 is provided on the side of the main beam 301 opposite to the support foot 303 , and a baffle 308 is provided on the side of the secondary beam 302 opposite to the support plate 309 . The support plate 309 is located at the bottom of the baffle 308 and contacts the baffle 308 .

[0031] According to the above structure, by setting a support plate 309 on the main beam 301 and setting a baffle 308 on the secondary beam 302 corresponding to the support plate 309, when the main beam 301 and the secondary beam 302 are close to each other, the baffle 308 and the support plate 309 are enclosed to form a enclosure, so that the bottom support 307 can be better protected during the process of lifting the prefabricated panel body 1, so that the prefabricated panel is not easy to collide with other panels lifted at the same time and cause damage.

[0032] The working principle of the utility model is as follows: the bottom support 307 supports the bottom of the precast panel body 1 to prevent the ground of the precast panel body 1 from being worn during the lifting process, and the outer side of the bottom support 307 extends to form a protective side arm that can better protect the side wings of the precast panel body 1, and has a relatively stable lifting environment without a large swing amplitude. In the lifting process, the precast panel body 1 is always between the main beam 301 and the auxiliary beam 302, thereby improving the safety and efficiency of the precast panel body 1 during the lifting construction process. When the precast panel body 1 is stacked, the support leg 305 first contacts the pads, and the precast panel body 1 is in a suspended state. Workers can identify the position of the precast holes at the bottom of the precast panel body 1 by observation, and issue corresponding instructions to install the precast panel body 1 accordingly with the bridge piers, so that it can be quickly stacked in sequence with the bridge piers.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
