Description

Technical Field

[0001] The utility model relates to the technical field of trestle corridors, in particular to an assembled trestle corridor. Background Art

[0002] Plants that need to transfer raw materials over a large area will generally build trestle corridors, so that the raw materials can be transferred in the passage of the trestle corridor (the space inside the trestle corridor is connected to form a passage), which can avoid occupying the ground space of the plant. At the same time, facilities such as conveyor tracks can be built in the passage to improve the efficiency of transfer. In the prior art, the trestle corridor generally includes a main line section, that is, extending from one end of the conveying channel to the other end. It can generally be constructed with an assembled structure, which can improve construction efficiency. In order to add entrances or exits to the middle section of the conveying channel, an inclined trestle corridor branch can often be added at the required location. The higher end is connected to the main line section of the trestle corridor, and the lower end is connected to the ground below or the loading platform. In this way, an entrance or exit can be added through the trestle corridor branch. In the prior art, the branch roads of the trestle corridors can also be constructed using prefabricated modules, generally in the same overlapping manner as the main line sections, but the main line sections are generally at the same level, and adjacent corridors (the main corridor is formed by connecting several corridors) can be well connected, and the installation is also relatively convenient. However, in order to shorten the length, the branch roads are generally inclined with a larger slope. In this way, the corridors located at higher places have a tendency to slide downward, and therefore will have a downward pushing force on the corridors below. During the installation process, more auxiliary stabilization measures need to be set (such as adding more scaffolding), which will lead to a decrease in overall efficiency. Utility Model Content

A first bolt is also connected between the mounting sleeve and the second support column.

[0007] Furthermore, both ends of the transverse support beam are respectively fixedly connected with upper convex plates extending upward, and second bolts are respectively connected between the upper convex plates and the second corridor and the third corridor or between two adjacent third corridors.

[0016] By providing a lap foundation by setting a high platform and a low platform on the cross support beam, a gap can be left between the second corridor and the third corridor, and between the third corridors without interfering with each other. During the installation process, the second corridor or the third corridor at an angle above can be relatively independent of the third corridor at an angle below, avoiding the application of a downward push force to the third corridor below.

DETAILED DESCRIPTION

[0026] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] In an exemplary embodiment, Figure 1 , 2As shown, the present embodiment provides an assembled trestle corridor, which includes a main line section, the main line section includes a plurality of first corridors 1 connected in sequence, and also includes a second corridor 2 connected to one of the first corridors 1 and inclined, and a plurality of third corridors 3 connected in sequence to the lower end of the second corridor 2. The main line section with a similar structure in the prior art is composed of a plurality of connected first corridors 1, and the second corridors 2 and third corridors 3 formed a branch. There can be multiple branches. A channel is opened on the side of a first corridor 1 at a position where it is required to be set to connect with the corresponding second corridor 2, wherein: the higher end of the second corridor 2 is overlapped on a pair of first support columns 4, and the lower end is overlapped on a transverse joist 5, and the two ends of each third corridor 3 are overlapped with a transverse joist 5 respectively. The first support column 4 can also be additionally provided with a first reinforcement block 6 and a second reinforcement block 7, the first reinforcement block 6 is used to assist in supporting the second corridor 2, and the second reinforcement block 7 is used for the first corridor 1 to overlap; the two ends of each transverse joist 5 are also connected with a second support column 8 respectively; the second corridor 2 and Gaps can be reserved between the adjacent third corridors 3 and between two adjacent third corridors 3 to avoid them directly abutting against each other, and an elastic frame 9 can be sandwiched at the gap position. The elastic frame 9 is a frame structure made of an elastic material (such as rubber), and together with the second corridor 2 and the third corridor 3, a channel is formed. The top of the elastic frame 9 is also covered with a gusset plate 10. The gusset plates 10 between the second corridor 2 and the adjacent third corridor 3 are also overlapped with each other, and the gusset plates 10 between the two adjacent third corridors 3 are also overlapped with each other, that is, a The gusset plate 10 covers the top of the gap, which can cover and protect the elastic frame 9 below and prevent rain and external dust from falling into the gap; the cross support beam 5 includes a high platform part 11 and a low platform part 12, and the high platform part 11 and the low platform part 12 are enclosed into a step structure and the top surface of the high platform part 11 is located above the low platform part 12, the lower ends of the second corridor 2 and the third corridor 3 are overlapped with the high platform part 11, and the higher end of the third corridor 3 is overlapped with the low platform part 12; the first corridor 1, the second corridor 2 and the third corridor 3 are all prefabricated concrete structures.

[0029] In the above embodiments, the second aisle 2 and several third aisles 3 form a branch. The first support column 4 is used for the higher end of the second aisle 2 to be lapped. Several cross beams 5 are used for the second aisle 2 and the third aisle 3 to be lapped. The lap foundations are respectively provided on the cross beams 5 through the high platform part 11 and the low platform part 12. In this way, gaps can be left between the second aisle 2 and the third aisle 3, and between the third aisles 3 without mutual contact. During the installation process, the second aisle 2 or the third aisle 3 obliquely above can be relatively independent of the third aisle 3 obliquely below, avoiding applying a downward pushing force to the third aisle 3 below. Therefore, it is more stable and only a small number of auxiliary stabilizing measures are required. As a result, the overall efficiency can be appropriately improved. More specifically, two second support columns 8 and a corresponding cross beam 5 form a support structure in the shape of "冂", and a step structure is formed on the top surface to provide lap foundations for the higher side and the lower side structures respectively. In this way, the structures at the higher position (the second aisle 2 or the third aisle 3) and the structures at the lower position (the third aisle 3) both apply forces to the cross beam 5 without directly applying forces to each other. That is to say, the structures at the higher position and the structures at the lower position are both supported by the cross beam 5 below and are relatively independent of each other. Therefore, the cross beam 5 can provide more stable support, making the entire installation process more stable than the prior art. The erection and disassembly of auxiliary stabilizing measures can be reduced, thereby reducing the overall time consumption and improving the overall efficiency.

[0030] As Figure 1 , 2 shown, in a further exemplary solution, mounting sleeves 13 are respectively fixedly connected to both ends of the bottom of the cross beam 5. A first top groove 14 located within the mounting sleeve 13 is also recessed on the cross beam 5. The upper end of the second support column 8 passes through the mounting sleeve 13 and is inserted into the first top groove 14. A first bolt 15 is also connected between the mounting sleeve 13 and the second support column 8. The first top groove 14 provides a connection space for the upper end of the second support column 8. The first bolt 15 plays a fixing role, increasing the connection strength between the second support column 8 and the cross beam 5 below the first top groove 14. More specifically, the upper end of the second support column 8 provided can be a larger-sized top entry head 16. The top entry head 16 passes through the mounting sleeve 13 and is inserted into the first top groove 14. The first bolt 15 connects the top entry head 16 and the mounting sleeve 13 to achieve the installation of the second support column 8;

[0031] Upper convex plates 17 extending upward are respectively fixedly connected to both ends of the cross beam 5. Second bolts 18 are respectively connected between the upper convex plates 17 and the second aisle 2 and the third aisle 3 or between two adjacent third aisles 3. That is, both ends of the step structure on the cross beam 5 provide left and right limits for the second aisle 2 and the third aisle 3 through the upper convex plates 17 respectively, and are connected by the second bolts 18 at the same time, so as to make the connection between the cross beam 5 and the second aisle 2 and the third aisle 3 more stable.

[0032] like Figure 1 , 3 As shown, the second corridor 2 and the third corridor 3 adjacent thereto, as well as the two adjacent third corridors 3, are separated, and a pair of connecting vertical plates 19 are provided on both sides thereof at the separated positions, and a third bolt 20 is provided between the connecting vertical plate 19 and the second corridor 2 and the third corridor 3 or between two adjacent third corridors 3, so that the connection strength between the connecting vertical plate 19 and the second corridor 2 and the third corridor 3 is increased on the side by the third bolt 20, so that the overall structure is further stabilized. In more detail, the connecting vertical plate 19 is also fixedly connected with a side convex plate 21 that can be inserted between the second corridor 2 and the third corridor 3 adjacent thereto, as well as between two adjacent third corridors 3, and the side convex plate 21 can be abutted against the outer side wall of the elastic frame 9, so that left and right limits are provided for both sides of the elastic frame 9, which helps to improve the stability of the overall structure.

[0033] like Figure 1 , 4As shown, in a more detailed exemplary solution, the lower ends of the second aisle 2 and the third aisle 3 are respectively fixedly connected with a first mounting frame 22, and the upper end of the third aisle 3 is also fixedly connected with a second mounting frame 23. The elastic frame 9 is clamped between the first mounting frame 22 and the adjacent second mounting frame 23. A fourth bolt 24 is also connected between the first mounting frame 22, the second mounting frame 23 and the upper end of the elastic frame 9 therebetween. In particular, the fourth bolt 24 is located inside the aisle, passing through the first mounting frame 22, the second mounting frame 23 and the elastic frame 9, making the connection of the three more stable. Further, a fifth bolt 25 is also connected between the two sides at the lower ends of the first mounting frame 22 and the second mounting frame 23. The fifth bolt 25 is located inside the elastic frame 9 and is not connected to the elastic frame 9. The fifth bolt 25 and the provided side convex plate 21 clamp the side of the elastic frame 9 therebetween. This can strengthen the connection strength of the first mounting frame 22 and the second mounting frame 23 while providing inner and outer side limits to the elastic frame 9, further contributing to the improvement of the overall structural stability. More specifically, the upper ends of the first mounting frame 22 and the second mounting frame 23 both extend above the second aisle 2 and the third aisle 3. The buckle plate 10 includes a covering section 26 covering the top surfaces of the first mounting frame 22 and the second mounting frame 23, a first clamping portion 27 and a second clamping portion 28 fixedly connected to both ends of the covering section 26, and a third clamping portion 29 fixedly connected to the middle section of the covering section and clamped between the first mounting frame 22 and the second mounting frame 23. The first clamping portion 27 abuts against the first mounting frame 22, and the second clamping portion 28 abuts against the second mounting frame 23. That is, the provided buckle plate 10 is integrally in a U-shaped structure and buckles on the tops of the first mounting frame 22 and the second mounting frame 23 exposed above. This can play a better protective role, and at the same time, the installation and disassembly are relatively convenient, facilitating subsequent maintenance. In particular, a third clamping portion 29 is also convexly provided at the middle section of the buckle plate 10. In this way, the third clamping portion 29 can also abut against the top surface of the lower elastic frame 9, providing upward limit to the top surface of the elastic frame 9. At the same time, the third clamping portion 29 being clamped into the gap also helps to provide the connection stability of the buckle plate 10 itself.

[0034] As Figure 1 , 2As shown in Figure 5, in a further exemplary embodiment, a first top block 30 is fixedly connected to the high platform portion 11, and a second top groove 31 for the first top block 30 to be inserted into the bottom surface of the first mounting frame 22 is provided, so that the first mounting frame 22 can be placed on the high platform portion 11 in a buckled manner. Similarly, a second top block 32 is fixedly connected to the low platform portion 12, and a third top groove 33 for the second top block 32 to be inserted into the bottom surface of the second mounting frame 23 is provided, so that the second mounting frame 23 can also be placed on the low platform portion 12 in a buckled manner. The first mounting frame 22 and the second mounting frame 23 can be relatively independent. A reinforcing straight plate 34 is also provided between the inner bottom surface of the first mounting frame 22 and the adjacent second mounting frame 23, and sixth bolts 35 are respectively provided between the reinforcing straight plate 34 and the first top block 30 and the second top block 32. The reinforcing straight plate 34 is provided in the channel through the sixth bolt 35 to strengthen the connection strength of the first mounting frame 22 and the second mounting frame 23. At the same time, the sixth bolt 35 also passes through the first mounting frame 22 and the second mounting frame 23 and is connected to the first top block 30 and the second top block 32 respectively, so that the first mounting frame 22 and the second mounting frame 23 are clamped between the reinforcing straight plate 34 and the cross support beam 5. Furthermore, the higher side and the lower side of the reinforcing straight plate 34 are also extended outward to the second corridor 2 or the third corridor 3, so that more sixth bolts 35 can be further added so that the reinforcing straight plate 34 is also connected to the second corridor 2 and the third corridor 3, and the overall stability is further improved; in more detail, the middle section of the reinforcing straight plate 34 is also fixedly connected with a lower convex plate 36, which can be inserted between the second mounting frame 23 and the third mounting frame 39, or between the two third mounting frames 39, and abutted against the inner bottom surface of the elastic frame 9 below, so that the reinforcing straight plate 34 provided in this way can also provide an upper limit for the lower side of the elastic frame 9, thereby making the elastic frame 9 more stable, which helps to further improve the stability of the overall structure.

[0035] like Figure 5 As shown, in a more detailed exemplary scheme, a reinforcing angle plate 37 is further provided between the side of the low platform 12 and the third corridor 3 adjacent thereto, and a seventh bolt 38 is further provided between the reinforcing angle plate 37 and the low platform 12 and the third corridor 3, respectively. The reinforcing angle plate 37 can be a split structure welded together, or can be an integral structure bent as a whole, so that the connection between the higher end of the third corridor 3 and the cross support beam 5 can be more stable, thereby making it difficult for the higher end of the inclined third corridor 3 to move downward, thereby ensuring the stability of the overall structure.

[0036] like Figure 1 , 5As shown in Figure 6, in a further exemplary scheme, the third mounting frame 39 is fixedly connected to the higher end of the second corridor 2, and the first reinforcing block 6 and the second reinforcing block 7 are respectively provided on both sides of the upper end of the first supporting column 4, and the second reinforcing block 7 is overlapped by the third mounting frame 39. More specifically, the top surfaces of the first reinforcing block 6 and the second reinforcing block 7 are flush with the top surface of the first supporting column 4, the top surface of the first supporting column 4 is recessed with a first card slot 40, the top surface of the first reinforcing block 6 is recessed with a second card slot 41, and the bottom surface of the third mounting frame 39 is fixedly connected with a first card block 42 and a second card block 43 which can be respectively inserted into the first card slot 40 and the second card slot 41, an eighth bolt 44 is further provided between the first supporting column 4 and the first card block 42, and a ninth bolt 45 is further provided between the first reinforcing block 6 and the second card block 43, the eighth bolt 44 connects the first card block 42 and the first supporting column 4, and the ninth bolt 45 connects the second card block 43 and the first reinforcing block 6 In this way, the third mounting frame 39 is connected to the first support column 4 and the first reinforcement block 6 respectively, and the third mounting frame 39 is more stably connected. Similar to the above-mentioned reinforcement angle plate 37, it plays a role in enhancing the connection strength between the second corridor 2 and the first support column 4. The higher end of the second corridor 2 is not easy to move downward, thereby ensuring the stability of the overall structure; in further detail, a third clamping block 46 and a fourth clamping block 47 can also be added to the bottom of the first corridor 1. The third clamping block 46 can be inserted into the first clamping groove 40 together with the first clamping block 42. The eighth bolt 44 passes through the first support column 4, the first clamping block 42, and the third clamping block 46, so that they are connected together. A third clamping groove 48 can be recessed on the second reinforcement block 7 for the fourth clamping block 47 to be inserted, and then the third clamping block 46 and the second reinforcement block 7 are connected by the tenth bolt 49. In this way, the first support column 4 and the first corridor 1 are more stably connected, and the overall structure is further stabilized.

[0037] like Figure 2 , 5 As shown in Figures 7 and 8, in a more detailed exemplary scheme, the top surfaces of the high platform portion 11 and the low platform portion 12 are respectively recessed with a first mounting groove 50 and a second mounting groove 52 for accommodating the lower ends of the first top block 30 and the second top block 32. A pair of first extension plates 53 are also fixedly connected at both ends of the first top block 30. The first extension plates 53 are fixed to the bottom of the first mounting groove 50 by an eleventh bolt 54. Similarly, a pair of second extension plates 56 are also fixedly connected at both ends of the second top block 32. The second extension plates 56 are fixed to the bottom of the second mounting groove 52 by a twelfth bolt 57. During the specific installation, the first top block 30 and the second top block 32 are first installed, and then concrete is added to fill the first mounting groove 50 and the second mounting groove 52, so that the first top block 30 and the second top block 32 are more firmly connected, and then other structures are installed.

Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
