Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for cap beam construction, and in particular to an anti-tipping device for a cap beam construction platform. Background Technology

[0002] In bridge engineering, the capping platform serves as a cornerstone of safety, and its stability and reliability are crucial, directly impacting construction safety and quality. Traditional capping platforms often reveal numerous shortcomings when facing complex construction environments and diverse loads.

[0003] Some existing construction platforms have simple structural designs and lack effective anti-tipping measures. When affected by factors such as lateral wind forces, vibrations from construction machinery, and uneven load distribution, the platforms are prone to tilting or even overturning, posing a serious threat to the lives of construction workers, hindering construction progress, and increasing project costs. For example, some platforms rely solely on simple support structures without considering the forces acting in different directions. Once a large lateral force occurs, it becomes difficult for them to maintain their balance and stability. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-overturning device for a cap beam construction platform to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anti-overturning device for a girder construction platform includes sand buckets mounted on side piers on both sides of a column. Each sand bucket has several pairs of anti-overturning components on its top. The tops of the two sand buckets on the same side are equipped with main beams, which are fixed to the tops of the sand buckets by the anti-overturning components. Several anti-overturning components are symmetrically and equally spaced on the tops of the two main beams. A distribution beam is fixed between two symmetrical anti-overturning components. A fixing limiting component is also provided on the column, which is fixed to one end of the main beam.

[0007] As a preferred embodiment of this utility model, the anti-overturning component includes a high-strength stud, a positioning steel plate is fitted on the high-strength stud, and an adjusting nut is threaded on the high-strength stud, with the adjusting nut located above the positioning steel plate.

[0008] In a preferred embodiment of this utility model, the fixing and limiting component includes a pair of semi-circular rings. The two semi-circular rings are sleeved on the outside of the column. Connecting ears are symmetrically arranged on both sides of the semi-circular rings. The two connecting ears of the two semi-circular rings are fixed together by a group of bolts. A support rod is provided on the side of the semi-circular ring. A support plate is provided on the top of the support rod. A U-shaped plate is provided on one side of the support plate. The bottom plate of the main beam is placed inside the U-shaped plate. A positioning component is provided on the top of the U-shaped plate.

[0009] In a preferred embodiment of this utility model, the positioning component includes an installation cylinder disposed on the top of the U-shaped plate, a positioning rod movably disposed inside the installation cylinder, the bottom of the positioning rod being inserted into the main beam, a pressure plate disposed on the positioning rod, the pressure plate being located inside the installation cylinder, a top pressure spring sleeved on the outside of the positioning rod, the top pressure spring being abutted between the pressure plate and the top surface inside the installation cylinder, and a gripping block disposed on the top of the positioning rod.

[0010] As a preferred embodiment of this utility model, the inner wall of the semicircular retaining ring is provided with several rows of retaining spikes, and a pair of patterned rubber pads are also provided on the inner wall of the semicircular retaining ring, with the two patterned rubber pads symmetrically arranged on the upper and lower sides of the retaining spikes.

[0011] In a preferred embodiment of this invention, both ends of the two main beams are connected by tie rods, and the tie rods are located on the outside of the column.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] 1. The sand buckets of this utility model serve as a supporting foundation and are distributed on the side piers on both sides of the column. Several pairs of anti-overturning components are set on the top of the sand buckets to limit the main beam from the bottom. The two sand buckets on the same side are tightly connected to the main beam through the anti-overturning components, which effectively prevents the main beam from shifting in the horizontal direction, ensures the stability of the platform in the lateral direction, and reduces the risk of the platform overturning due to lateral forces.

[0014] 2. The anti-overturning components symmetrically and at equal intervals are arranged on the top of the two main beams, and the distribution beams fixed by these components form a stable superstructure system. This arrangement enables the distribution beams to evenly transfer the force to the main beams when bearing construction loads, thereby enhancing the stability of the entire platform in the direction perpendicular to the columns.

[0015] 3. This utility model uses a semi-circular retaining ring, which is tightly fitted onto the outside of the column by fixing the retaining component. The connection between the retaining ring and the column is ensured by the fixing method of connecting ears and bolt groups. The barbs and patterned rubber pads on the inner wall of the semi-circular retaining ring increase the friction and adhesion with the column, effectively preventing the retaining ring from sliding or rotating on the column. This provides a stable support point at one end of the main beam, ensuring the reliability of the connection between the main beam and the column, thereby enhancing the overall stability of the entire platform.

[0016] 4. This utility model uses the positioning component at the top of the U-shaped plate to accurately limit the position of the main beam. The positioning rod is inserted into the positioning groove of the main beam under the action of the top pressure spring, ensuring that the main beam can be accurately positioned during installation and remain stable during subsequent construction, preventing displacement due to vibration or other external forces, and further improving the reliability and stability of the connection between the main beam and the sand bucket and column.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] like Figures 1-6 As shown, the present invention proposes an anti-overturning device for a cap beam construction platform, which includes a sand bucket 1, an anti-overturning component 2, a main beam 3, a fixing and limiting component 7, and a distribution beam 4, etc. The components cooperate with each other to ensure the stability and reliability of the platform.

[0026] First, the sand buckets 1 are set up. The sand buckets 1 are placed on the side piers on both sides of the column 5 to provide basic support for the entire platform. Each sand bucket 1 is equipped with several pairs of anti-overturning components 2 on top. These anti-overturning components 2 play a key role in preventing the platform from overturning in the future.

[0027] The main beam 3, constructed from 45A I-beams, serves as a load-bearing beam and spans the tops of two sand buckets 1 on the same side. It is securely fixed to the sand buckets 1 by anti-overturning components 2, ensuring the horizontal stability of the main beam 3. Several anti-overturning components 2 are also symmetrically and evenly spaced on the tops of the two main beams 3. These components, in conjunction with the anti-overturning components 2 on the sand buckets 1 below, further enhance the platform's anti-overturning capability. Then, the distribution beam 4 is fixed between two symmetrical anti-overturning components 2, forming a stable platform bearing surface, thus preventing safety accidents caused by the collapse of the support system. Simultaneously, the installation of anti-overturning components improves construction standardization, ensures the spacing of the distribution beams during platform installation, and serves a positioning function.

[0028] The fixed limiting component 7 is installed on the column 5 and is tightly fixed to one end of the main beam 3, effectively limiting the longitudinal displacement of the main beam 3. The fixed limiting component 7 consists of a pair of semi-circular rings 70. The two semi-circular rings 70 are tightly fitted on the outside of the column 5. Connecting ears 71 are symmetrically arranged on both sides of the semi-circular rings 70. The connecting ears 71 of the two semi-circular rings 70 are fixed together by several bolt groups 72 to ensure that the semi-circular rings 70 firmly hold the column 5. A support rod 73 is provided on the side of the semi-circular rings 70. The support plate 74 at the top of the support rod 73 is used to support the main beam 3. A pair of U-shaped plates 75 on one side of the support plate 74 are used to accommodate the bottom plate of the main beam 3, realizing the initial positioning of the main beam 3.

[0029] To further ensure the fixing effect of the main beam 3, a positioning component 78 is provided at the top of each U-shaped plate 75. A positioning rod 781 is movably installed in the mounting cylinder 780 of the positioning component 78. When the bottom plate of the main beam 3 is placed in the U-shaped plate 75, the positioning rod 781 is inserted into the preset hole on the main beam 3 under the action of the top pressure spring 782, so as to achieve precise positioning of the main beam 3. The pressure plate 783 on the positioning rod 781 and the top pressure spring 782 work together to ensure the stable insertion and fixing effect of the positioning rod 781. The grab block 784 at the top of the positioning rod 781 facilitates the operation of the construction personnel.

[0030] On the inner wall of the semicircular retaining ring 70, there are several rows of retaining spikes 76 and a pair of patterned rubber pads 77. The retaining spikes 76 and patterned rubber pads 77 increase the friction and adhesion between the semicircular retaining ring 70 and the column 5, preventing the semicircular retaining ring 70 from sliding or rotating on the column 5, and further improving the stability of the fixed limiting component 7.

[0031] In addition, to prevent the main beams from overturning laterally, 16mm tie rods 6 are used to connect both ends of the two I-beam main beams 3 through the web of the I-beams. The tie rods 6 are located on the outside of the columns 5. The function of the tie rods 6 is to enhance the integrity and stability between the two main beams 3, so that they can work together to share the weight when bearing construction loads, thereby ensuring the structural safety and stability of the entire cap beam construction platform.

[0032] When installing the platform before the construction of the cap beam, firstly, the array of fixed limiting components 7 are precisely fixed on the column 5. The installation position should be accurately determined according to the actual height of the main beam 3 to ensure the accuracy and stability of the subsequent installation. Then, several sand buckets 1 are placed on the side piers on both sides of the two columns 5. During the placement process, their positions need to be strictly measured to ensure that the positions of the sand buckets 1 on the same side of the two columns 5 are completely symmetrical.

[0033] Subsequently, a truck crane is used to lift the main beam 3 above the sand bucket 1. During the lifting process, it is ensured that both ends of the main beam 3 are accurately placed into the U-shaped plate 75. During this process, the operators need to manually lift several positioning rods 781 to make room for the insertion of the main beam 3. After the bottom plate of the main beam 3 is fully inserted, the positioning rods 781 are released. At this time, the top pressure spring 782 will push the positioning rods 781 into the positioning grooves pre-set in the main beam 3, thereby realizing the limiting and fixing of the main beam 3 and ensuring that it will not be displaced during subsequent construction.

[0034] At the same time, it is necessary to ensure that the main beam 3 is located between the array of anti-overturning components 2 to further enhance its stability. Then, the construction personnel manually rotate the positioning steel plate 21 to accurately cover the bottom plate of the main beam 3. Next, they use tools to tighten the adjusting nut 22 so that the positioning steel plate 21 is tightly pressed onto the bottom plate of the main beam 3, thus completing the secondary limiting reinforcement of the main beam 3 and effectively preventing it from shaking or shifting during construction.

[0035] Finally, several distribution beams 4 were placed stably on the two main beams 3, with a spacing of 30cm between each distribution beam. The distribution beams 4 were then firmly fixed with anti-overturning components 2. Thus, the installation of the entire platform was successfully completed, providing a safe and stable operating platform for the subsequent cap beam construction.
