Description

Technical Field

[0001] This utility model relates to the technical field of precast concrete component bases, specifically to a box girder fabrication platform. Background Technology

[0002] In bridge construction, box girders are key load-bearing components, and their quality directly affects the overall performance and service life of the bridge. Currently, traditional box girder fabrication platforms mostly adopt fixed structures, which have obvious defects in the box girder curing process. Box girder curing requires water spraying to ensure the strength and durability of the concrete, and the ambient temperature needs to be monitored.

[0003] Regarding the uniformity of curing, the traditional fixed-position water spray nozzles on the beam fabrication platform are not properly arranged, which is not conducive to providing a uniform humidity field distribution, affecting concrete shrinkage and strength formation, and thus leading to problems such as cracks and insufficient strength in the box girder. Therefore, it is necessary to meet the curing requirements of box girders and improve curing efficiency and quality. In view of this, we propose a new type of box girder fabrication platform.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Please see Figures 1-4 The present invention will describe the above technical solution in detail through the following embodiments:

[0030] The box girder fabrication platform in this embodiment includes, for example: Figure 1 The concrete abutment foundation 1 shown is used to support the box girder body 7. In order to facilitate maintenance, the abutment has a pre-embedded guide pipe 2 inside, and a valve 6 is installed at the water inlet end of the guide pipe 2. At the same time, the guide pipe 2 has evenly distributed branch pipes 21 along both sides of the concrete abutment foundation 1. The inlet end of the guide pipe 2 is used to connect to external water for maintenance.

[0031] This embodiment sets up four evenly distributed maintenance components, such as... Figures 2-4 The structure shown has four sets of telescopic units 3 that can be detachably installed on both sides of the concrete pedestal foundation 1. Each telescopic unit 3 is detachably equipped with an atomizing nozzle 4, and the atomizing nozzle 4 and the branch pipe 21 are connected by a soft water pipe.

[0032] like Figure 4 The structure shown includes a telescopic unit 3 comprising a sleeve 32 into which a telescopic rod 31 is inserted via a limiting pin 34. For example, in this embodiment... Figure 1 In terms of position, the top of the sleeve rod 32 is connected to a support block 35 for detachable installation of the atomizing nozzle 4; its telescopic rod 31 is kept tilted to control the atomizing nozzle 4 to face both sides of the box girder body 7, so as to spray atomized oxidizing water to its sides; in order to facilitate installation, the bottom of the sleeve rod 32 in this embodiment is fixedly connected to a locking block 33, which is inserted into the slot 101 to facilitate disassembly and adjustment of the spraying position.

[0033] It should be noted that during the spraying of curing water, excessive curing water will flow back along the outer wall of the box girder body 7. Therefore, in this embodiment, if the amount of curing water is excessive, it will flow back along the outer wall of the box girder body 7. Figure 1 In terms of location, return trays 5 are detachably installed on both sides of the upper surface of the concrete pedestal foundation 1. The bottom of the return trays 5 is equipped with a filter screen, which can filter the returned curing water. In order to better adjust the temperature and humidity conditions of the curing water spray, temperature and humidity sensors are installed on both sides of the concrete pedestal foundation 1 to detect the ambient temperature and humidity and ensure a good curing environment.

[0034] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
