Description

Technical Field

[0001] This application relates to the field of building construction, and specifically to a support structure for installing and protecting a cross-channel steel beam. Background Technology

[0002] With the rapid development of construction technology, steel structure bridges are widely used in urban bridge construction due to their good strength and self-weight. Steel structure bridges have many advantages, but during the installation process, steel pipe supports need to be set up according to the actual situation on site. At the same time, when the steel beam crosses the urban passage, professional protective scaffolding needs to be set up to ensure the normal passage during construction. The conventional practice is to first install a safety protection scaffolding at the place where the steel beam crosses the passage, and then install the steel beam assembly bracket after acceptance to carry out the installation and construction of the steel structure bridge.

[0003] The channel protection scaffolding is set below the steel beam assembly bracket to receive objects that accidentally fall from above to prevent falling objects from damaging vehicles and pedestrians passing through the urban channel. The channel protection scaffolding does not need to bear the specific structure of the steel structure bridge, so its bearing capacity is designed to be low, and the bearing capacity of the supporting columns on both sides is also designed to be low accordingly. The material, size and construction plan of the supporting columns are all affected by the low bearing capacity requirements.

[0004] The steel beam assembly bracket is set above the safety protection scaffolding to provide an installation position for the steel structure bridge. The upper surface of the steel beam assembly bracket is used to bear the specific structure of the steel structure bridge, so its bearing capacity is designed to be high. The bearing capacity design of the supporting columns on both sides is also high accordingly. The material, size and construction plan of the supporting columns are all affected by the high bearing capacity requirements.

[0005] The existing channel protection scaffolding and steel beam installation bracket are set separately, and the two structures are independent of each other. During construction, the urban channel needs to be cleared once to complete the construction of the channel protection scaffolding, and then the urban channel needs to be cleared twice to complete the construction of the steel beam assembly bracket. The urban channel needs to be cleared and constructed at least twice, resulting in a long time of road occupation, a greater impact on traffic, and a long construction period. As the construction period increases, the safety risk also increases.

[0006] In addition, since the channel protection scaffolding and the steel beam installation bracket are separately arranged, the two structures are independent of each other. During construction, it is necessary to first install the steel pipe columns of the channel protection scaffolding on the ground on both sides of the urban channel, and perform the top structure construction on the steel pipe columns on both sides of the channel protection scaffolding. Then, install the steel pipe columns of the steel beam assembly bracket on the ground on both sides of the urban channel, and perform the top structure construction on the steel pipe columns on both sides of the steel beam assembly bracket. The lifting operation workload is large. The steel pipe columns of the steel beam assembly bracket are located on the outside of the steel pipe columns of the channel protection scaffolding and the bearing capacities of the two steel pipe columns are different. The material cost is large and the design is complex.

[0007] In addition, in some construction scenarios, initially only the passage protection shed frame is designed and built. When the steel beam assembly support needs to be built later, extension construction will be carried out on the steel pipe columns on both sides of the passage protection shed frame, and the top structure of the steel beam assembly support will be constructed on the extended part. However, the extension construction on the existing steel pipe columns itself will bring complex construction problems, and since the bearing capacity of the steel columns of the passage protection shed frame cannot meet the bearing capacity requirements of the steel beam assembly support, its safety cannot be guaranteed.

[0008] In summary, in the conventional double-layer support structure across the passage, when the passage protection shed frame and the steel beam assembly support are designed separately, it will occupy the passage space, and multiple relocations are required, resulting in great difficulty in construction organization, high construction costs and material costs; when the passage protection shed frame and the steel beam assembly support are designed integrally, due to the lack of unified design planning in the early stage, the construction is complex, the construction safety risk is relatively high, and materials are easily wasted. Summary of the Invention

[0009] This application provides a support structure for installing and protecting steel beams across a passage, which can solve the technical problems of complex construction, high construction difficulty, high safety risk, and high cost caused by the separate setting of the steel beam installation support and the passage protection shed frame in the prior art.

[0010] In a first aspect, an embodiment of this application provides a support structure for installing and protecting steel beams across a passage, and the structure includes:

[0011] Multiple groups of steel pipe columns that are evenly distributed on both sides of the passage along the passage direction and are matched with the bearing capacity of the steel beam assembly support;

[0012] On one side of each steel pipe column close to the passage, there is a support corbel. A protection frame distribution beam is erected between the two support corbels of the same group of steel pipe columns, and an installation frame distribution beam is erected between the same group of steel pipe columns and is located above the protection frame distribution beam;

[0013] Protection steel plates are laid on all the support corbels along the passage direction.

[0014] In this embodiment, the urban passage is used for the passage of vehicles. Multiple groups or pairs of steel pipe columns are set along the passage direction of the urban passage. Each group of steel pipe columns is relatively set on both sides of the passage. The bearing capacity of the steel pipe columns matches that of the steel beam assembly bracket, and can simultaneously bear the steel beam assembly bracket and the passage protection scaffolding. Support brackets are set on the side of each group of steel pipe columns on one side of the passage. Protection frame distribution beams are set on the two support brackets for later erection of protection steel plates thereon to form a passage protection scaffolding structure. A mounting frame distribution beam is set on the top of each group of steel pipe columns. The bottoms of both ends of the mounting frame distribution beam 5 are respectively connected to the top of the steel pipe columns. The construction of the steel beam to be erected on the mounting frame distribution beam is used for the later installation of the steel beam to be erected.

[0015] The structural form of the cross-channel steel beam installation bracket that also serves as a protective bracket is integrated on the basis of the separate settings of the conventional steel beam installation bracket and the cross-channel protective bracket, forming a set of bracket forms that combine installation and protection functions. Structurally, this bracket form adopts a unified steel pipe column, and a protective layer is added by setting a corbel on the steel pipe column. Compared with the conventional cross-channel bracket set separately, it fully utilizes the pipe pile material. The steel beam assembly bracket and the channel protection scaffolding share the same steel pipe column, which reduces the investment in pipe pile materials and reduces the occupation of the channel site. In terms of construction, it can reduce the occupation of the channel by two installation constructions, reducing the construction difficulty and safety risks. Combined with the first aspect, in one embodiment, the steel pipe columns are all set vertically.

[0016] Combined with the first aspect, in one embodiment, the supporting brackets are all arranged at a preset passage height of the passage.

[0017] In combination with the first aspect, in one embodiment, the supporting corbel includes a horizontal I-beam and a diagonal bracing steel pipe connected to each other.

[0018] Combined with the first aspect, in one embodiment, one end of each of the horizontal I-beams is connected to a steel pipe column, and the other end extends to the inside of the channel, and each of the horizontal I-beams is arranged horizontally;

[0019] The protective steel plate is installed above the horizontal I-beam of the protective corbel.

[0020] Combined with the first aspect, in one embodiment, the protective steel plate is detachably mounted on the protective corbels between the same group of steel pipe columns.

[0021] Combined with the first aspect, in one embodiment, one end of the diagonal bracing steel pipe is connected to the steel pipe column, and the other end is connected to the bottom of the horizontal I-beam.

[0022] Combined with the first aspect, in one embodiment, the side of the steel pipe column close to the passage is coated with a reflective layer.

[0023] In combination with the first aspect, in one embodiment, the covering height of the reflective layer reaches the preset passing height of the channel.

[0024] In combination with the first aspect, in one embodiment, the protective corbel is welded to the steel pipe column.

[0025] The beneficial effects brought by the technical solution provided by the embodiments of the present application include:

[0026] The structural form of the installation bracket for the cross-channel steel beam of the present invention that also serves as a protective bracket integrates on the basis of separately setting the conventional steel beam installation bracket and the cross-channel protective bracket, forming a set of brackets that combine both installation and protection functions. Structurally, this bracket form uses a unified steel pipe column, and the structural design of the steel pipe column matches the bearing capacity of the steel beam assembly bracket. A protective layer is added by setting a corbel on the steel pipe column. Compared with the way of separately setting the conventional cross-channel brackets, it makes full use of the pipe pile materials, reduces the input of pipe pile materials, and at the same time reduces the occupation of the channel site; in construction, it can reduce the occupation of the channel by two installation constructions, and reduce the construction difficulty and safety risks.

[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0032] To make the purpose, technical solution and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0033] In a first aspect, the embodiments of the present application provide a bracket structure for installing and protecting a cross-channel steel beam.

[0034] In one embodiment, with reference to Figure 1 and Figure 2 , Figure 1 FIG. is a schematic structural diagram of an embodiment of a bracket structure for installing and protecting a cross-channel steel beam in the present application, Figure 2 is Figure 1 a schematic cross-sectional view taken along line 2-2 in Figure 1 and Figure 2 . As shown in

[0035] , the bracket structure for installing and protecting a cross-channel steel beam includes:

[0036] A plurality of groups of steel pipe columns 1 that are uniformly distributed on both sides of the channel along the channel traveling direction and are matched with the bearing capacity of the steel beam assembly brackets;

[0037] On the side of each steel pipe column 1 close to the channel, a support corbel 2 is provided. A protection frame distribution beam 3 is erected between the two support corbels 2 of the same group of steel pipe columns 1, and an installation frame distribution beam 5 located above the protection frame distribution beam is erected between the same group of steel pipe columns 1;

[0038] On all the support corbels 2 along the channel direction, a protection steel plate 4 is laid.

[0039] In this embodiment, the urban channel is used for vehicle passage. A plurality of groups or pairs of steel pipe columns 1 are arranged along the urban channel passing direction. Each group of steel pipe columns 1 is relatively arranged on both sides of the channel. The steel pipe columns 1 are matched with the bearing capacity of the steel beam assembly brackets, and can simultaneously bear the steel beam assembly brackets and the channel protection shed. On the side of each group of steel pipe columns 1 on one side of the channel, a support corbel 2 is provided, and a protection frame distribution beam 3 is erected on the two support corbels 2 for later erection of a protection steel plate 4 thereon to form a channel protection shed structure. An installation frame distribution beam 5 is erected on the top of each group of steel pipe columns 1. The bottom ends of both ends of the installation frame distribution beam 5 are respectively connected to the top of the steel pipe column 1. The construction of the steel beam 6 to be erected on the installation frame distribution beam 5 is for later installation of the steel beam 6 to be erected.

[0040] Further, in one embodiment, the above-mentioned protection corbel is welded to the above-mentioned steel pipe column 1.

[0041] In a specific embodiment, the installation of the cross-channel steel beam installation and protection bracket includes the following steps:

[0042] Step 1: Install steel pipe columns 1 on the road surfaces on both sides of the channel, and determine the spacing of the steel pipe columns 1 in the advancing direction of the channel according to the channel conditions and the steel beam to be erected.

[0043] Step 2: Install the support bracket 2 by welding at a height of H1 from the bottom of the steel pipe column 1. The bracket can be welded to the steel pipe column 1 in advance according to the installation height and hoisted together with the steel pipe column 1 on-site. Attention should be paid to the sectioning of the steel pipe column 1 and the installation height of the support bracket 2.

[0044] Step 3: After the support bracket 2 passes the acceptance, hoist the protection frame distribution beam 3 onto the support bracket 2, adjust the position and then fix it by spot welding to ensure that the protection frame distribution beam 3 does not displace and is more convenient to disassemble.

[0045] Step 4: Hoist the cut-to-length protection steel plate 4 onto the protection frame distribution beam 3, and fix it to the protection frame distribution beam 3 by spot welding after adjustment.

[0046] Step 5: Continue to extend the steel pipe column 1 to the designed height H (H is greater than H1), and install the installation frame distribution beam 5 at the top of the column. The installation frame distribution beam 5 is welded to the steel pipe column 1 to complete the installation of the whole set of bracket systems.

[0047] In this embodiment, the cross-channel steel beam installation and protection bracket includes a steel pipe column 1, a support bracket 2, a protection frame distribution beam 3, a protection steel plate 4, an installation frame distribution beam 5, etc. Among them, the support bracket 2 of the protection bracket is set at a certain height (H1) of the steel pipe pile according to the channel passage requirements, and the support bracket 2 is welded to the steel pipe pile of the steel pipe column 1; the protection frame distribution beam 3 is placed on the support bracket 2 and fixed by spot welding; the protection steel plate 4 is laid and fixed on the protection frame distribution beam 3; after extending the steel pipe pile (total height H), continue to install the steel installation frame distribution beam 5 at the top of the column to complete the installation of the whole set of bracket systems. Among them, during the installation and erection of the upper installation frame distribution beam 5, since the protection frame distribution beam 3 has been completed, the actual construction has been isolated from the channel, greatly reducing the construction safety risk.

[0048] Further, in an embodiment, the above-mentioned steel pipe columns 1 are all vertically arranged.

[0049] In this embodiment, the ground lines on both sides of the channel may be uneven. The steel pipe columns 1 are preferably vertically arranged, and the protection frame distribution beam 3 and the installation frame distribution beam 5 are preferably horizontally arranged. The protection frame distribution beam 3 and the installation frame distribution beam 5 only need to be perpendicular to the steel pipe column 1 when installed on it for the convenience of construction.

[0050] Further, in one embodiment, the steel pipe column 1 includes a base portion and an extension portion connected to the top of the base portion.

[0051] In this embodiment, at the same installation position, the base portion of the steel pipe column 1 is constructed first. A support bracket 2 is provided on the side of the base portion close to the passage. Then, a protective frame distribution beam 3 and a protective steel plate 4 are erected between the support brackets 2 to form a passage protection support layer. After the passage protection support layer is installed, the actual construction is isolated from the passage, greatly reducing the construction safety risk. Then, the extension portion is continued to be constructed. The structures of the base portion and the extension portion are essentially the same, and the construction is relatively simple. After extending the base portion to form the extension portion of the steel pipe column 1, a connection frame is provided at the top of the extension portion to connect the installation frame distribution beam 5.

[0052] The bracket for installing and protecting the cross-passage steel beam has good usability, economy and safety. Specifically, it can reduce the cumbersome construction of separately setting two sets of bracket systems, optimize the use of the bracket steel pipe column 1, effectively reduce the waste of section steel materials, and at the same time reduce the traditional two-time cross-road construction to one time, which can reduce the construction safety risk brought by the high-risk cross-road operation.

[0053] Further, in one embodiment, the above-mentioned support brackets 2 are all arranged at the preset passing height of the passage.

[0054] In this embodiment, arranging the support brackets 2 at the preset passing height of the passage can ensure the passage of vehicles in the passage while avoiding the support brackets 2 and the subsequent passage protection support layer being set too high, resulting in waste of construction costs.

[0055] Further, in one embodiment, the above-mentioned support bracket 2 includes a horizontal I-beam and a diagonal bracing steel pipe connected to each other.

[0056] In this embodiment, the ground lines on both sides of the passage may be uneven. The steel pipe column 1 is preferably arranged vertically, and the protective frame distribution beam 3 and the installation frame distribution beam 5 are preferably arranged horizontally. The protective frame distribution beam 3 and the installation frame distribution beam 5 only need to be perpendicular to the steel pipe column 1 when installed, so as to facilitate construction.

[0057] Further, in one embodiment, one end of each of the above-mentioned horizontal I-beams is connected to the steel pipe column 1, and the other end extends to the inner side of the passage, and the above-mentioned horizontal I-beams are all horizontally arranged;

[0058] The above-mentioned protective steel plate 4 is erected above the horizontal I-beam of the protective bracket.

[0059] In this embodiment, the bracket for installing and protecting the cross-channel steel beam includes a steel pipe column 1, a supporting bracket 2, a protection frame distribution beam 3, a protection steel plate 4, an installation frame distribution beam 5, etc. Among them, the supporting bracket 2 of the protection bracket is set at a certain height (H1) of the steel pipe pile according to the passage requirements of the channel, and the supporting bracket 2 is welded to the steel pipe pile of the steel pipe column 1; the protection frame distribution beam 3 is placed on the supporting bracket 2 and fixed by spot welding; the protection steel plate 4 is laid and fixed on the protection frame distribution beam 3; after extending the steel pipe pile (total height H), the column top steel installation frame distribution beam 5 is continued to be installed to complete the installation of the entire bracket system. Among them, during the installation process of the upper installation frame distribution beam 5, since the protection frame distribution beam 3 has been completed, the actual construction has been isolated from the channel, greatly reducing the construction safety risk.

[0060] The ground lines on both sides of the channel may be uneven. The steel pipe column 1 is preferably set vertically, and the protection frame distribution beam 3 and the installation frame distribution beam 5 are preferably set horizontally. The protection frame distribution beam 3 and the installation frame distribution beam 5 only need to be perpendicular to the steel pipe column 1 when installed on it for the convenience of construction.

[0061] Further, in one embodiment, the above-mentioned protection steel plate 4 is detachably installed on the protection brackets between the same group of steel pipe columns 1.

[0062] Further, in one embodiment, one end of each of the above-mentioned diagonal bracing steel pipes is connected to the steel pipe column 1, and the other end is connected to the bottom of the horizontal I-beam.

[0063] Further, in one embodiment, the side of the above-mentioned steel pipe column 1 close to the channel is coated with a reflective layer.

[0064] In this embodiment, the steel pipe columns 1 are installed on the road surfaces on both sides of the channel. The spacing of the steel pipe columns 1 is determined according to the channel conditions and the steel beam to be erected. The steel pipe columns 1 within the channel height range need to be painted with eye-catching reflective paint to form a reflective layer to improve construction safety.

[0065] Further, in one embodiment, the covering height of the above-mentioned reflective layer reaches the preset passage height of the channel.
