[0026] In order to better understand the purpose, structure and function of the utility model, the bridge frame embedded part of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] An embodiment of the utility model provides a new type of bridge frame embedded part, including a shell 1, which is a cubic structure formed by two L-shaped steel plates spliced ​​into an upper and lower opening. The front and rear surfaces of the shell 1 are symmetrically and evenly spaced with a plurality of wire pipe holes 11. The upper opening of the shell 1 is sealed with tape as a sealing structure 6 to prevent concrete from entering the shell 1 during pouring; angle steels 2 are symmetrically welded on the outer sides of the upper and lower parts of the shell 1 as fixed wings so as to be fixed on the template 4; each angle steel 2 is a cubic structure, and the length of each angle steel 2 is equal to the side length of the adjacent side of the shell 1; along the length direction of the shell 1, each angle steel 2 is provided with at least two reserved holes 21, and along the width direction of the shell 1, each angle steel 2 is provided with at least one reserved hole 21; the connecting component 3 connects the shell 1 and the template 4 through the reserved hole 21 at the lower part of the shell 1.

[0028] Combination Figures 1 to 3 As shown in Figures 4 and 5, in the first embodiment of the utility model, along the length direction of the shell 1, two reserved holes 21 are arranged on each angle steel 2, and the distance between the two reserved holes 21 is greater than the distance from the edge of the angle steel 2 to the adjacent reserved hole 21; along the width direction of the shell 1, a reserved hole 21 is arranged in the middle of each angle steel 2.

[0029] like Figure 4 As shown, in the second embodiment of the utility model, three reserved holes 21 are arranged on each angle steel 2 along the length direction of the shell 1, and the distance between two adjacent reserved holes 21 is equal and greater than the distance from the edge of the angle steel 2 to the adjacent reserved hole 21; along the width direction of the shell 1, a reserved hole 21 is arranged in the middle of each angle steel 2.

[0030] The production method involved in the utility model:

[0031] (1) Making the shell 1 of the embedded parts: In the early stage, the embedded parts of the bridge are customized according to the size of the bridge to ensure that the horizontal size and height are appropriate. Two L-shaped steel plates are welded into a cubic shell 1 by electric welding. A number of wire tube holes 11 are opened symmetrically and evenly spaced on the front and back surfaces of the shell 1. The specific number is determined according to the number of wire tubes entering the bridge on each layer. Since the shell 1 is mainly used to pass the bridge, it must be guaranteed to have sufficient hardness.

[0032] (2) Making the fixing wings of the embedded parts: symmetrically weld the angle steels 2 of the cube structure on the outer sides of the upper and lower parts of the shell 1, and make holes at the predetermined positions of the angle steels 2 to form fixing wings for fixing the embedded parts.

[0033] In order to prevent the embedded parts from falling off due to loose connection with the formwork 4, on the one hand, it is ensured that the number of reserved holes 21 set on each angle steel 2 is specifically determined according to the actual length of the bridge. In addition, once the number of reserved holes 21 set on each angle steel 2 is greater than one along the length or width direction of the shell 1, it is necessary to follow that the distance between two adjacent reserved holes 21 is equal, and the distance between two adjacent reserved holes 21 is greater than the distance from the edge of the angle steel 2 to the adjacent reserved hole 21. For example, when the aspect ratio of the shell 1 is 200:100, two reserved holes 21 can be opened on the long side; when the aspect ratio of the shell 1 is 400:100, three reserved holes 21 can be opened on the long side. More implementation cases are not repeated here.

[0034] On the other hand, dovetail screws are used to pass through the reserved holes 21 on the fixed wings at the bottom of the shell 1 to fix the embedded parts to the template 4; and each steel wire rope 5 is passed through the reserved holes 21 on the upper part of the shell 1 in turn along the length direction or width direction of the shell 1, and finally wound around two dovetail screws symmetrically placed at the bottom of the shell 1, to ensure that the embedded parts and the aluminum template 4 are better fixed, thereby avoiding the phenomenon of loose connection on the aluminum template 4.

[0035] (3) Installing embedded parts: Before fixing the embedded parts, determine the number and size of wire tubes entering the bridge on each layer, reserve the corresponding tube holes for the wire tubes, and install nuts of the same specifications as those in the wire tube holes 11 on the embedded parts on the reserved tube holes, so that the wire tubes can pass through the wire tube holes 11 on the embedded parts and the tube holes on each layer of the bridge in sequence when laying and fixing them;

[0036] During the main roof construction phase, the embedded parts are precisely positioned. The distance between the roof and the wall is controlled at 5cm~10mm, and the position is marked. The combined embedded parts and the template 4 are placed at the marked position, and the upper open part of the embedded parts is wrapped and sealed with tape to prevent concrete from entering during pouring; after the positioning is accurate, the embedded parts are fixed and installed according to the marked position; after the civil engineering reinforcement construction is completed, the position of the embedded parts is confirmed again to ensure that the embedded parts are not offset.

[0037] (4) Installing the bridge: After the embedded parts are installed, pour concrete along the outside of the embedded parts, clean the remaining tape at the upper opening of the embedded parts, repair the damaged parts, and then pass the bridge directly through the embedded parts to ensure that the inside of the embedded parts and the installed bridge are in perfect contact with each other, thereby reducing the fireproof sealing area and eliminating the steps and costs of secondary repair and fireproof sealing of the reserved holes. This simplifies the construction process, makes the operation simple, and saves manpower and material costs.
