Description

Technical Field

[0001] This utility model relates to the field of Bailey beam technology, specifically a detachable Bailey beam support structure. Background Technology

[0002] Bailey bridges are widely used as an important load-bearing component in many engineering fields such as building construction, bridge erection, and large equipment installation. They have advantages such as simple structure, convenient assembly, and strong load-bearing capacity, and can quickly build temporary or semi-permanent support platforms to meet the construction needs of different engineering scenarios. The existing Bailey bridge support structure is mainly composed of crossbeams and columns. The columns are composed of multiple pipes connected by flanges and multiple bolts. Adjacent columns also need to be connected by welding or bolts to ensure the overall stability of the support structure. Therefore, the installation and dismantling process is relatively complicated.

[0003] To address this issue, we have designed a detachable Bailey beam support structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a detachable Bailey beam support structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable Bailey beam support structure, comprising support columns and crossbeams. The support columns consist of upper support columns, middle support columns, and lower support columns inserted sequentially from top to bottom. The middle support column has two pairs of vertically distributed U-shaped grooves fixed on its side. The upper and lower support columns each have a pair of U-shaped grooves fixed on their sides. Each U-shaped groove has a through hole on its side. The U-shaped grooves of four vertically connected and adjacent support columns can be connected and fixed together by a four-column connector. The U-shaped grooves of two vertically connected support columns can also be connected and fixed together by a two-column connector. A lower base plate is fixed at the top of the upper support column. Four threaded columns arranged in a rectangular array are fixed on the lower base plate. Each threaded column is provided with a lower nut and an upper nut. Two upper base plates are fixed at the bottom of the crossbeam. Each upper base plate has four through holes. The four threaded columns on the lower base plate pass through these four through holes respectively. The upper base plate is sandwiched between the lower nut and the upper nut.

[0006] As a preferred embodiment of this utility model, the top ends of the middle support and the lower support are provided with insertion holes, and the bottom ends of the upper support and the middle support are fixed with insertion blocks that can cooperate with the insertion holes.

[0007] As a preferred technical solution of this utility model, the four-column connector consists of two horizontal bars, three first vertical bars and two diagonal braces. The three first vertical bars are fixed at equal intervals between the two horizontal bars. The two diagonal braces are respectively fixed at the diagonal of the two rectangular frames formed by the horizontal bars and the first vertical bars. Each horizontal bar has through holes on both sides. The four ends of the two horizontal bars can be inserted into the U-shaped grooves of the four pillars that are connected vertically and adjacent to each other horizontally and are fixed with bolts.

[0008] As a preferred technical solution of this utility model, the two-column connector consists of a second vertical rod and two protrusions. The two protrusions are respectively fixed at both ends of the side of the second vertical rod. Each protrusion has a through hole on its side. The two protrusions can be inserted into the U-shaped grooves of the two vertically connected pillars and fixed with bolts.

[0009] As a preferred technical solution of this utility model, the bottom end of the lower support column is fixed with a base, and the base has a reserved mounting hole for connecting the foundation.

[0010] As a preferred technical solution of this utility model, a Bailey beam body can be erected on the top of the crossbeam, and the crossbeam has pre-drilled mounting holes and can be fixed to the Bailey beam body with bolts.

[0011] Compared with the prior art, this utility model provides a detachable Bailey beam support structure, which has the following advantages:

[0012] This detachable Bailey beam support structure, through the insertion of plugs and sockets, and in conjunction with four-column connectors or two-column connectors, allows for the quick connection and fixation of the upper, middle, and lower supports together. Compared to the traditional flange connection method, it greatly reduces the amount of bolts used, making it easier for workers to install and disassemble. In addition, the four-column connectors can also directly connect two adjacent support columns together, ensuring the overall stability of the support structure and eliminating the need to weld brackets between two support columns.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-6A detachable Bailey beam support structure includes a support column 1 comprising an upper support column 101, a middle support column 102, and a lower support column 103. All three columns are tubular to reduce the overall weight of the support structure. The top of the middle support column 102 and the lower support column 103 are provided with insertion holes 105, and the bottom of the upper support column 101 and the middle support column 102 are fixed with insertion blocks 106 that mate with the insertion holes 105. The support column 1 is composed of the upper support column 101, the middle support column 102, and the lower support column 103 sequentially inserted from top to bottom through the engagement of the insertion blocks 106 and the insertion holes 105. The insertion blocks 106 and the insertion holes 105 use irregularly shaped blocks and matching irregularly shaped holes, such as polygonal prisms, to restrict rotation between the columns. The side of the middle support column 102 is fixed... There are two pairs of vertically distributed U-shaped grooves 104. Each of the upper support column 101 and lower support column 103 has a pair of U-shaped grooves 104 fixed to its side. Each U-shaped groove 104 has a through hole on its side. For four supports that are vertically connected and horizontally adjacent, a four-column connector 3 is used for connection and fixation. The four-column connector 3 consists of two horizontal bars 301, three first vertical bars 302, and two diagonal braces 303. The three first vertical bars 302 are fixed at equal intervals between the two horizontal bars 301. The two diagonal braces 303 are respectively fixed at the diagonal of the two rectangular frames formed by the horizontal bars 301 and the first vertical bars 302. Each horizontal bar 301 has through holes on both ends of its side. The four ends of the two horizontal bars 301 are inserted into the U-shaped grooves 104 of the four supports, and then bolts are used to pass through the U-shaped grooves 104. The four vertically connected and horizontally adjacent pillars are fixed together as a whole by fixing the through holes at the ends of the U-shaped groove 104 and the crossbar 301. For the two vertically connected pillars, a two-pillar connector 4 is used for connection and fixation. The two-pillar connector 4 consists of a second vertical rod 401 and two protrusions 402. The two protrusions 402 are fixed to the two ends of the side of the second vertical rod 401, and each protrusion 402 has a through hole on its side. The two protrusions 402 are inserted into the U-shaped groove 104 of the two pillars respectively, and bolts are used to fix them through the through holes of the U-shaped groove 104 and the protrusions 402. The two vertically connected pillars are fixed together as a whole by fixing the top of the upper pillar 101 to the bottom plate 5. Four bolts arranged in a rectangular array are fixed on the bottom plate 5. The crossbeam 2 is connected to the support column 1 by threaded posts 6, each with a lower nut 7 and an upper nut 8. Two upper base plates 9 are fixed to the bottom of the crossbeam 2, each with four through holes. The four threaded posts 6 on the lower base plate 5 are passed through these four through holes. By adjusting the positions of the lower nuts 7 and upper nuts 8, the upper base plate 9 is clamped between the lower nuts 7 and upper nuts 8, thus connecting the crossbeam 2 to the support column 1. A base 10 is fixed to the bottom end of the lower support column 103. Mounting holes are pre-drilled on the base 10 for connecting to the foundation. Bolts are passed through these mounting holes and connected to the foundation, thus connecting and fixing the base 10 to the foundation. A Bailey beam body 11 is erected on top of the crossbeam 2. Mounting holes are pre-drilled on the crossbeam 2. Bolts are passed through the mounting holes of the crossbeam 2 and the Bailey beam body 11 and nuts are connected.This allows for the connection and fixation of the crossbeam 2 and the Bailey beam 11.

[0022] Example 2: In actual use, the length of the support column 1 can be increased according to actual needs. When increasing the length, multiple middle support columns 102 are connected to the insertion block 106 through the insertion hole 105, and the connected middle support columns 102 are fixed together by the four-column connector 3 or the two-column connector 4 to form a longer middle support column 102. Then, the upper support column 101 and the lower support column 103 are connected and fixed to the extended middle support column 102 to complete the lengthening of the support column 1.

[0023] Usage Procedure: During assembly of this detachable Bailey beam support structure, first, the support columns 1 are spliced. The insert 106 of the upper column 101 is inserted into the insertion hole 105 at the top of the middle column 102, and the insert 106 of the middle column 102 is inserted into the insertion hole 105 at the top of the lower column 103. For the connection points of the four columns that are connected vertically and horizontally, a four-column connector 3 is used. The four ends of the two crossbars 301 are respectively inserted into the corresponding U-shaped grooves 104 of the four columns, and bolts are passed through the U-shaped grooves 104. Secure the crossbar 301 by screwing in the through holes and nuts. For the connection between the two upper and lower support columns, use the two-column connector 4. Insert the two protrusions 402 into the U-shaped grooves 104 of the two support columns respectively. Secure the support column 1 by screwing in the through holes of the U-shaped grooves 104 and the protrusions 402 and screwing in the nuts. After the support column 1 is assembled, connect the base 10 at the bottom of the lower support column 103 to the foundation with bolts through the reserved mounting holes. Then install the crossbeam 2. First, thread the four threads on the lower base plate 5. Connect the lower nut 7 to column 6 and adjust its height position on the threaded column 6. Then, align the four through holes of the upper base plate 9 with the four threaded columns 6 on the lower base plate 5 and insert them so that the lower surface of the upper base plate 9 contacts the lower nut 7. Next, connect the upper nut 8 to the four threaded columns 6 and tighten the upper nut 8 to make it fit tightly against the upper surface of the upper base plate 9, completing the connection between the crossbeam 2 and the support column 1. Finally, erect the Bailey beam body 11 on top of the crossbeam 2 and use bolts to pass through the pre-drilled mounting holes in the crossbeam 2 and the Bailey beam body 11. Tighten the nuts to secure it. When disassembling the support structure, remove the upper nut 8 from the threaded post 6 to remove the crossbeam. After removing the four-post connector 3 and the two-post connector 4, the supports can be separated. If the top of the crossbeam 2 is blocked, preventing the support from moving upwards to pull the insert 106 out of the socket 105, the lower nut 7 can be tightened to the lowest end of the threaded post 6 to lower the overall height of the support structure, so that there is enough space to pull the insert 106 out of the socket 105.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
