DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the practical embodiment to clearly and completely describe the technical solution in the practical embodiment. Obviously, the described embodiment is only a part of the embodiment of the practical embodiment, not all of the embodiments. Based on the embodiment in the practical embodiment, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this practical embodiment.

[0034] As attached Figure 1-6 The shown embodiment is an integrated structure of a concrete box beam and embedded components for a railway bridge, comprising a box beam body 1, wherein a steel frame 2 is arranged inside the box beam body 1, and a plurality of embedded components 5 are evenly welded to the bottom end of the steel frame 2, a connecting component 3 is installed at the bottom end of each of the embedded components 5, and a supporting component 4 is installed at the bottom end of each of the connecting components 3.

[0035] In the specific implementation, multiple groups of embedded components 5 are uniformly welded on the steel skeleton 2 set in the concrete box beam body 1 used in the railway bridge, so that each embedded component 5 is integrally fixedly connected to the box beam body 1, and the connecting component 3 is installed at the bottom of each embedded component 5 before the entire box beam body 1 is formed. The installation of the connecting component 3 facilitates the subsequent installation and fixation of the supporting component 4. When it is necessary to set up an I-beam at the bottom of the box beam body 1 to improve the overall strength, the setting of each supporting component 4 and the connection component 3 at the top can cooperate to install the I-beam Fixed, so there is no need to subsequently drill holes in the box beam body 1 to install the fixing parts to install the I-beam, thereby avoiding damage to the structure of the box beam body 1, thereby further improving the overall strength, and in the process of installing the I-beam, after the I-beam is pre-installed in each supporting component 4, the I-beam can be moved by pushing the I-beam, which is convenient for adjusting the position of the I-beam, and the width range of the locking mouth can be adjusted according to the width size of the I-beam, so that the I-beam can be clamped and fixed, thereby improving the convenience of installing the I-beam.

[0036] As attached Figure 4 As shown, the embedded component 5 includes a welding plate 501, and the welding plate 501 is welded on the steel frame 2;

[0037] A plurality of first bolt rods 502 are symmetrically welded to the bottom end of the welding plate 501 .

[0038] There are four first bolt rods 502 , which are symmetrically welded to the bottom of the welding plate 501 , and the bottom ends of the four first bolt rods 502 are commonly connected to the connecting assembly 3 .

[0039] In specific implementation, the welding plate 501 is welded to the steel skeleton 2, and multiple first bolts 502 are welded at the bottom of the welding plate 501, so that the bottom ends of the multiple first bolts 502 can be connected to the connecting component 3, so that when the box beam body 1 is prefabricated with concrete, the embedded component 5 and the box beam body 1 can form a whole, thereby increasing the strength of the connection between the embedded component 5 and the connecting component 3, so as to facilitate the support when the I-beam is installed.

[0040] As attached Figure 5 As shown, the connection component 3 includes a fixing plate 301, and the fixing plate 301 is bolted to the bottom end of the embedded component 5;

[0041] A connecting plate 302, wherein the connecting plate 302 is vertically welded to the bottom of the fixing plate 301;

[0042] The mounting plate 303 is welded to the bottom end of the connecting plate 302 , and the mounting plate 303 and the fixing plate 301 are both circular and coaxially arranged, and the bottom end of the mounting plate 303 is connected to the supporting assembly 4 .

[0043] The fixing plate 301 is symmetrically provided with four bolt holes, and each first bolt rod 502 is connected and matched with a corresponding bolt hole.

[0044] In specific implementation, the fixing plate 301 is connected to each first bolt rod 502 so that the connecting component 3 is connected and fixed to the embedded component 5 as a whole. By welding the connecting plate 302 between the fixing plate 301 and the mounting plate 303, an installation gap can be reserved between the fixing plate 301 and the mounting plate 303, thereby facilitating the installation of the supporting component 4 when the I-beam is installed later.

[0045] As attached Figure 6 As shown, the support assembly 4 includes two second bolt rods 401, and the two second bolt rods 401 are symmetrically connected to the bottom end of the mounting plate 303;

[0046] Two connecting frames 402, each of the connecting frames 402 is connected to a corresponding second bolt rod 401;

[0047] A shaft connecting rod 403, wherein the shaft connecting rod 403 is connected to two connecting frames 402;

[0048] The steel sleeve 404 is sleeved on the shaft connecting rod 403 .

[0050] In specific implementation, the top end of the second bolt rod 401 is connected to the mounting plate 303, and the bottom end is connected to the connecting frame 402. The height of the connecting frame 402 can be adjusted by adjusting the locking length of the second bolt rod 401, so that the shaft connecting rod 403 at the bottom end can be adjusted with the height adjustment, so that the supporting position of the I-beam can be adjusted, so that the I-beam fits as closely as possible to the bottom of the box beam body 1, thereby facilitating the improvement of the fixity of the I-beam installation. When the I-beam is installed, the I-beam can be on the shaft connecting rod 403. With the support of the sleeved steel sleeve 404, when the I-beam is pushed, the I-beam can be moved, thereby adjusting the position of the I-beam at the bottom of the box beam body 1, thereby improving the convenience of installation. After the I-beam is installed, the axial connecting rod 403 supports the bottom of the I-beam, and the connecting frame 402 connects the axial connecting rod 403. Under the connection of the connecting component 3 and the embedded component 5, the box beam body 1 bears the weight of the I-beam. Since the embedded component 5 and the box beam body 1 are a whole, the firmness of the I-beam after installation is improved.

[0051] As attached Figure 5 and Figure 6 As shown, two adjusting grooves are symmetrically provided on the mounting plate 303 , the two adjusting grooves are respectively arranged on both sides of the connecting plate 302 , and the top end of each second bolt rod 401 is respectively connected to the corresponding adjusting groove.

[0052] In specific implementation, the second bolt rod 401 can slide in the adjustment groove, so that the distance between the second bolt rods 401 can be adjusted, so that the distance between the two connecting frames 402 can be adjusted, so that it can be appropriately adjusted according to the width size of the I-beam to ensure that both sides of the I-beam are clamped and fixed.

[0053] As attached Figure 6 As shown, threads are provided at both ends of the shaft connecting rod 403, and nuts are screwed on both sides of the connecting frame 402 connected to the two ends of the shaft connecting rod 403.

[0054] In specific implementation, the installation limit of the shaft connecting rod 403 is limited by the nut, so that the distance between the connecting frames 402 can be limited, so that when the I-beam vibrates, the connecting frame 402 can vibrate synchronously with the I-beam, thereby preventing the I-beam from sliding on the shaft connecting rod 403, thereby reducing the wear on the shaft connecting rod 403 and the connecting frame 402, thereby increasing the overall service life and improving the stability of the I-beam support.

[0055] As attached Figure 6 As shown, the mounting plate 303, two second bolt rods 401, two connecting frames 402, an axial connecting rod 403 and a steel sleeve 404 form a locking mechanism, and a locking opening is formed in the locking mechanism, and the locking opening is used to fasten the I-beam.

[0056] In specific implementation, the height dimension of the locking mouth can be adjusted by adjusting the locking position of the two second bolt rods 401, and the distance between the connecting frames 402 at both ends of the axial connecting rod 403 is adjusted, and the two second bolt rods 401 slide in the adjustment groove, and the distance between the two second bolt rods 401 is adjusted, so that the width dimension of the locking mouth can be adjusted, so that the locking mouth can lock the I-beam.
