"upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.

The description will be given taking as an example the prefabrication of the sectional box girder shown in fig. 1 and 2. As can be seen from fig. 1, the temporary Zhang Kong and the lifting hole 102 in the section box girder 1 penetrate through the top plate 103 of the section box girder 1, and the temporary hole 101 is taken as an example, the hole at one end of the temporary hole is positioned at the top of the section box girder 1, and the hole at the other end of the temporary hole is positioned at the hole wall of the middle hole 104 of the section box girder 1.

To pre-form the segmented box girder shown in fig. 1 and 2, a box girder mold 2 shown in fig. 3 may be used. The box girder mold 2 comprises two end molds 201, side molds 202 and an inner mold 203, wherein the inner mold 203 is used to form the middle hole 104 of the segmented box girder 1.

As shown in fig. 4, fig. 5 and fig. 6, the pre-burying device for forming a hole in a process hole of a matched prefabricated section box girder (hereinafter referred to as pre-burying device) provided in the embodiment of the application includes: a girder 3, at least one end of which is used for being connected with the box girder die 2; the frame beam 3 is provided with a plug hole 4, the plug hole 4 corresponds to the arrangement position of the process hole of the section box beam 1, and penetrates through the frame beam 3 along the radial direction of the frame beam 3; the embedded rod 5 is connected with the frame beam 3 in an inserting way through the inserting hole 4, and the outer diameter of the embedded rod 5 is matched with the aperture of the inserting hole 4; the first end 505 of the embedded rod 5 extends out of the girder erection 3 and into the girder box die 2.

The ends of the frame beams 3 may be connected to the end form 201 in the box beam mold 2 by welding or fastening (e.g., bolting, etc.), for example, as shown in fig. 5. In the related art, one of the two end molds 201 of the box girder mold 2 is a fixed end mold and the other is a movable end mold. The fixed end die is used as an assembly foundation of the box girder die 2, and the perpendicularity of the die surface of the fixed end die and the central axis of the section box girder 1 to be poured can be well guaranteed, so that if only one end of the frame girder 3 is connected with the box girder die 2, the frame girder 3 can be connected with the fixed end die to ensure that the embedded rod 5 inserted on the frame girder 3 is positioned at a design position in the box girder die 2.

In view of the above, the upper plate 103 is penetrated by the upper Zhang Kong and the lifting hole 102 of the segmental box girder 1, and the bottom of the upper plate 103 is formed by the inner mold 203, so that in this embodiment, the first end 505 of the embedded rod 5 can abut against the top of the inner mold 203, and the inner mold 203 can be used as an axial supporting structure of the embedded rod 5, as shown in fig. 6.

Illustratively, when the process holes in the section box girder 1 are formed only by the pre-buried bars 5 (i.e., the pre-buried bars 5 are in contact with concrete when the section box girder 1 is poured), the outer diameters of the pre-buried bars 5, the diameters of the plugging holes 4, and the diameters of the process holes are the same. When the process hole is formed through the embedded pipe, the embedded rod 5 is only used for positioning the embedded pipe (namely, the embedded pipe is in contact with concrete when the section box girder 1 is poured), the embedded rod 5 is inserted into the embedded pipe, and the outer diameter of the embedded rod 5, the aperture of the inserting hole 4 and the inner diameter of the embedded pipe are the same.

Illustratively, the number of the plugging holes 4 provided on the frame beam 3 is equal to or greater than the number of the process holes of the segment box beam 1.

Before the pre-burying device in this embodiment is used, the box girder mold 2 needs to be installed (including installing the reinforcement cage into the box girder mold 2). At least one end of the frame beam 3 is connected to the end mould 201 of the box beam mould 2, so that the position of the inserting holes 4 on the frame beam 3 is aligned with the position of the process holes (the position of the process holes is determined according to the structural design of the section box beam 1) of the section box beam 1 to be poured. For example, as shown in fig. 1 and 6, when the process hole is located at the top of the segmented box girder 1, the end of the frame girder 3 is connected to the top of the end mold 201.

After the girder 3 is fixed, the embedded rod 5 is inserted into the inserting hole 4 corresponding to the process hole, the first end 505 of the embedded rod 5 passes through the inserting hole 4 and then enters the box girder die 2, and the insertion depth of the embedded rod 5 corresponds to the depth of the process hole. For example, as shown in fig. 1 and 6, when the process hole penetrates the top plate 103 of the segmented box girder 1, the first end 505 of the embedded rod 5 may be made to abut against the top of the inner mold 203 of the box girder mold 2. Because the external diameter of the embedded rod 5 is matched with the aperture of the plug hole 4, the embedded rod 5 cannot move or incline in an uncontrolled radial direction in the plug hole 4, and the molding quality of the process hole can be ensured.

After the embedded bars 5 are inserted, concrete can be poured into the box girder die 2. After the concrete in the box girder die 2 is initially set, the embedded rod 5 can be pulled out from the inserting hole 4, and the process hole is formed at the moment.

According to the embedded device provided by the embodiment of the application, the girder erection 3 is connected with the box girder die 2, so that the position between the girder erection 3 and the section box girder 1 can be kept unchanged in the section box girder 1 forming process. Because the splicing holes 4 arranged on the frame beam 3 correspond to the process holes of the section box beam 1, the embedded bars 5 can be ensured to be accurately positioned at the process holes after passing through the splicing holes 4. Because the outer diameter of the embedded rod 5 is matched with the aperture of the inserting hole 4, the inserting hole 4 can limit the embedded rod 5, so that the embedded rod 5 is prevented from radial movement or inclination, and the embedded rod 5 is ensured to be reliably kept at a preset position all the time in the process of forming the process hole.

Meanwhile, as the embedded rod 5 is connected with the frame beam 3 in an inserting way through the inserting hole 4, the embedded rod 5 only needs to be axially moved along the inserting hole 4 when the embedded rod 5 is dismounted, and the use is convenient.

As shown in fig. 4, 5, 7 and 8, in some embodiments, the frame beam 3 includes a first frame beam 301, the first frame beam 301 being a tubular structure; the plug hole 4 comprises a first plug hole 401 arranged on the first frame beam 301, the embedded rod 5 comprises a first embedded rod 501, and the outer diameter of the first embedded rod 501 is matched with the aperture of the first plug hole 401.

Illustratively, the radial cross-sectional outer profile of the first frame beam 301 is square, i.e. the first frame beam 301 is a beam consisting of square tubes.

The first plug hole 401 corresponds to the hoisting hole 102 of the section box girder 1 to be poured, as shown in fig. 2 and 5, for example. In combination with the foregoing, that is, the first jack hole 401 can be coaxially aligned with the hoist hole 102, and the aperture of the first jack hole 401 is the same as the designed inner diameter of the hoist hole 102 (the inner diameter of the concrete hole or the inner diameter of the embedded pipe).

Illustratively, the outer diameter of the first pre-buried bar 501 is matched with the aperture of the first jack 401, that is, the outer diameter of the first pre-buried bar 501 is the same as the aperture of the first jack 401.

Illustratively, the first frame beam 301 is provided with two first jack holes 401 at intervals along the axial direction (such as the X1 direction in fig. 4).

Taking the structure shown in fig. 4, 7 and 8 as an example, the first jack hole 401 penetrates the first frame member 301, and the first frame member 301 has a tubular structure. When the first embedded rod 501 passes through the first plug hole 401, the first end 505 of the first embedded rod passes through the wall of one side of the tubular structure to enter the interior of the tubular structure, and then passes through the wall of the opposite side of the tubular structure to extend out, i.e. the tubular structure can position the first embedded rod 501 twice through the walls of the opposite sides of the tubular structure. Therefore, the positioning accuracy of the first frame beam 301 and the first plug hole 401 to the first embedded bar 501 can be improved by arranging the first frame beam 301 in a tubular structure, which is helpful for improving the quality of the process hole formed by the embedded bar 5.

As shown in fig. 4, 5, 6, 9 and 10, in some embodiments, the frame beam 3 further includes a second frame beam 302 spaced parallel to the first frame beam 301, the plugging hole 4 includes a second plugging hole 402 disposed on the second frame beam 302, and the pre-buried rod 5 includes a second pre-buried rod 502, and an outer diameter of the second pre-buried rod 502 matches an aperture of the second plugging hole 402.

Illustratively, the second socket hole 402 corresponds to the face Zhang Kong 101 of the segmental box girder 1 to be poured, as shown in fig. 2 and 5.

Illustratively, all the process holes on the section box girder 1 are divided into a plurality of hole groups according to the arrangement rule, and the plugging holes 4 in the same pre-buried device only correspond to the process holes in one hole group. When prefabricating the segmental box girder 1, one box girder die 2 can be provided with two or more pre-buried devices, so that a splicing hole 4 is arranged at a preset position of each process hole in the box girder die 2 to correspond to the preset position.

For example, taking the section box girder 1 shown in fig. 2 as an example, all the process holes can be divided into two axisymmetric hole groups, and the plugging holes 4 of one pre-buried device can be arranged to correspond to the process holes in one of the hole groups. In prefabrication, two identical pre-embedding devices are used, one of which is arranged corresponding to one hole set and the other is arranged corresponding to the other hole set after rotating horizontally 180 degrees, as shown in fig. 5.

As shown in fig. 4, 9, and 10, in some embodiments, the second frame beam 302 includes a temporary Zhang Kong positioning mechanism 3021 and two sub-beams 3022 respectively connected to the temporary Zhang Kong positioning mechanism 3021, wherein an end of the sub-beams 3022 remote from the temporary Zhang Kong positioning mechanism 3021 is used for connection to the box beam mold 2; along a radial direction (e.g., Y1 direction in fig. 4) of the second frame beam 302, the width of the temporary Zhang Kong positioning mechanism 3021 is greater than the width of the sub-beam 3022; the second plugging hole 402 is disposed in the positioning mechanism 3021 of the temporary Zhang Kong.

Taking the structure of the section box girder 1 shown in fig. 2 as an example, the faces Zhang Kong 101 on the section box girder 1 can be divided into two groups, and each group comprises four faces Zhang Kong 101 distributed in an array.

The second frame beam 302 is configured to include a wider face Zhang Kong positioning mechanism 3021 for providing four second mating holes 402 corresponding to the four faces Zhang Kong 101 of the array. Since the four faces Zhang Kong 101 are distributed more compactly, the length (dimension along the X1 direction in fig. 4) of the face Zhang Kong positioning mechanism 3021 can be correspondingly set smaller for material saving.

To enable the attachment of the temporary Zhang Kong positioning mechanism 3021 to the box girder mold 2. The second frame beam 302 further includes two sub beams 3022 connected to the positioning mechanism 3021 of the temporary Zhang Kong, and one end of the two sub beams 3022 away from the positioning mechanism 3021 of the temporary Zhang Kong can be connected to the box beam mold 2, so as to ensure that the position between the positioning mechanism 3021 of the temporary Zhang Kong and the box beam mold 2 is relatively fixed during prefabrication.

As shown in fig. 5, 6, 9 and 10, in some embodiments, the positioning mechanism 3021 of the temporary Zhang Kong includes at least two positioning plates 30211 spaced in parallel along a direction away from the box girder mold 2, and the second plugging holes 402 penetrate all of the positioning plates 30211.

When the second embedded rod 502 is connected with the second frame beam 302 in an inserting way through the second inserting hole 402, the first end 505 of the second embedded rod 502 sequentially passes through all positioning plates 30211, each positioning plate 30211 can position the second embedded rod 502, namely, at least two positioning plates 30211 can position the second embedded rod 502 at least twice, the positioning precision of the second frame beam 302 and the second inserting hole 402 to the second embedded rod 502 can be improved, and the quality of process holes formed through the embedded rods 5 can be improved.

As shown in fig. 5 and 6, in some embodiments, two ends of the sub beams 3022 near the positioning mechanism 3021 of the face Zhang Kong are respectively connected to two opposite side walls of the positioning mechanism 3021 of the face Zhang Kong.

In order to shorten the axial length of the sub-beam 3022, one end of the sub-beam 3022 may be connected to the side wall of the positioning mechanism 3021 of the temporary Zhang Kong by welding or the like, and the other end may be connected to the box beam mold 2. At this time, the length of the second frame beam 302 (i.e., the dimension in the X1 direction in fig. 4) is the sum of the lengths of the two sub beams 3022 and the length of the positioning mechanism 3021 of the temporary Zhang Kong.

As shown in fig. 4, in some embodiments, two of the sub-beams 3022 are arranged concentrically.

The two sub beams 3022 are concentrically arranged, so that the distribution of supporting force provided by the sub beams 3022 to the positioning mechanism 3021 of the temporary Zhang Kong is reasonable.

As shown in fig. 4, 5 and 6, in some embodiments, two ends of the first frame beam 301 are connected to one connecting piece 6, and two ends of the second frame beam 302 are connected to one connecting piece 6, respectively; the box girder mold 2 includes an end mold 201, and the connection member 6 is connected to the top of the end mold 201.

Illustratively, the connector 6 is formed of a square tube having an axial direction (i.e., in the Y1 direction in fig. 4) perpendicular to the axial directions of the first frame rail 301 and the second frame rail 302 (i.e., in the X1 direction in fig. 4).

Illustratively, the connector 6 is located on a side of the first 301 and second 302 frame beams that is adjacent to the box beam mold 2. As in fig. 6.

The end parts of the first frame beam 301 and the end part of the second frame beam 302 on the same side are connected to the same connecting piece 6, so that on one hand, the relative distance between the first frame beam 301 and the second frame beam 302 can be kept unchanged, and on the other hand, the connecting piece 6 is directly connected with the end mould 201, so that the first frame beam 301 and the second frame beam 302 can be simultaneously fixed on the end mould 201, and the embedded device of the embodiment is more convenient to use.

The connecting piece 6 is connected to the top of the end mold 201, that is, the connecting piece 6 is located above the end mold 201, and the end mold 201 can support the connecting piece 6, so that the girder 3 in the pre-burying device of the embodiment is erected above the box girder mold 2.

As shown in fig. 6 and 11, in some embodiments, the second end 506 of the pre-buried rod 5 extends out of the frame beam 3, and the second end 506 is connected with a hanging ring 503; the second end 506 of the pre-buried rod 5 is remote from the first end 505 of the pre-buried rod 5.

After the embedded rod 5 and the frame beam 3 are inserted, the second end 506 of the embedded rod 5 is exposed (located on the side, far away from the box beam die 2, of the frame beam 3), in order to facilitate pulling out the embedded rod 5, a hanging ring 503 is arranged at the second end 506 of the embedded rod 5, so that an outward pulling force is applied to the embedded rod 5 through a finger or a hanging hook.

As shown in fig. 11, in some embodiments, the pre-buried rod 5 is in a tubular structure, the second end 506 of the pre-buried rod 5 is connected with a plugging plate 504, and the hanging ring 503 is in threaded connection with the plugging plate 504.

In order to reduce the weight of the pre-buried bar 5, the pre-buried bar 5 may be provided in a tubular structure. Before the insertion hole 4 is inserted, the opening of the pipe hole at the first end of the embedded rod 5 can be plugged through rubberized fabric or other structural members, so that concrete is prevented from entering the pipe hole of the tubular structure during prefabrication.

For installing the hanging ring, a plugging plate 504 is arranged at the second end 506 of the embedded rod 5, and a threaded through hole is directly arranged on the plugging plate 504, or a through hole is arranged on the plugging plate 504 and a nut concentric with the through hole is fixed. When the hanging ring 503 is installed, the threaded post of the hanging ring 503 is screwed into the threaded through hole or the nut.
