Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a temporary support structure for reinforcing steel beams and its assembly and use method. Background Technology

[0002] Concrete-supported beam structures are widely used in deep foundation pit engineering. These beams are characterized by a large number of top and bottom reinforcing bars, as well as numerous rows of reinforcing bars on the sides. Before tying and fixing the reinforcing bar skeleton at the joints of the supporting beam, measures must be taken to temporarily limit and secure the reinforcing bars.

[0003] Currently, during the reinforcement binding process of supporting beams, scaffolds erected with steel pipes and couplers are generally used as temporary supports for the reinforcement, which are then removed after the beam reinforcement cage is bound and fixed. However, due to the large working area required for erecting steel pipe scaffolds and the large size of the steel pipes, they are only suitable for supporting the top reinforcement of the beam; and after the reinforcement cage is bound and fixed, the steel pipe scaffolds are difficult to dismantle. Summary of the Invention

[0004] To address the aforementioned problems, this invention discloses a temporary support structure for reinforcing bars of a supporting beam and its assembly and usage method. This effectively solves the problem in the prior art where the supports erected using steel pipe fasteners during the binding of reinforcing bars of a supporting beam are difficult to dismantle as temporary supports for the reinforcing bars and cannot be used for supporting the side reinforcing bars of the beam.

[0005] On one hand, the present invention discloses a temporary support structure for the reinforcing steel of a supporting beam, comprising: an L-shaped limiting member, a supporting pipe, and two opposing columns;

[0006] Both columns are hollow structures. A strip-shaped hole is opened on one side of the two columns that are facing away from each other. A first insertion hole is opened at intervals along the height direction on the upper part of the opposite side of the two columns, and the first insertion holes on the two columns are correspondingly arranged. A second insertion hole is opened at intervals along the height direction on two sides of each column that are perpendicular to the extension direction of the support beam, and the second insertion holes on the two columns are correspondingly arranged. The L-shaped limiting member is inserted into the second insertion hole.

[0007] The support tube is detachably fixed between the two columns by a pin inserted into the first insertion hole. The support tube is used to place the top reinforcing steel of the support beam. A limit block is fixedly provided on the inner wall of each column below each second insertion hole. The L-shaped limit member includes a first rod and a second rod perpendicularly connected to the first rod. One end of the first rod is inserted into the second insertion hole, and the end of the first rod located inside the column is vertically provided with a pier. When the L-shaped limit member is rotated to the point where the lower surface of the pier is located on the limit block, the second rod is horizontally positioned, and the end of the second rod is located between the two columns to place the side reinforcing steel of the support beam.

[0008] In some of the embodiments, the column is a steel column.

[0009] In some of these embodiments, the pin has a T-shaped structure.

[0010] In some embodiments, the pin is a bolt.

[0011] In some embodiments, the L-shaped limiting member is an L-shaped steel bar.

[0012] In some of these embodiments, the support fitting is a steel pipe.

[0013] In some embodiments, the limiting block is a steel plate.

[0014] In some embodiments, the steel plate is welded and fixed to the inner wall of the column.

[0015] On the other hand, the present invention also discloses a method for assembling and using a temporary support structure for reinforcing steel bars of a supporting beam, which, based on the aforementioned temporary support structure for reinforcing steel bars of a supporting beam, includes the following steps:

[0016] Step S1: Based on the cross-sectional design dimensions of the support beam, the thickness of the top protective layer, and the dimensions of the top longitudinal reinforcement, select the first insertion hole on the column and insert the pin.

[0017] Step S2: After the column is installed in place, a support pipe is sleeved between the two pins to serve as the top steel reinforcement support for the support beam.

[0018] Step S3: According to the position of the side reinforcement of the designed support beam, adjust the L-shaped limiting member on the column so that the pier head is placed on the limiting block, and the second rod of the L-shaped limiting member is set horizontally so that the second rod serves as a support for the side reinforcement of the support beam.

[0019] Step S4: After all the reinforcing bars of the support beam are tied using the temporary support structure of the support beam steel bars, adjust the L-shaped limiting piece to make the second rod vertical, and remove the support pipe and the column.

[0020] Compared with the prior art, the above invention has at least one of the following advantages or beneficial effects:

[0021] I. The temporary support structure for the reinforcing steel bars of the supporting beam of the present invention can improve the construction efficiency of workers, speed up the construction progress, and save construction time and labor.

[0022] Second, the temporary support structure for the supporting beam reinforcement of the present invention can be adapted to the support beam reinforcement installation system with different beam heights and different beam side reinforcement design dimensions. It can realize the application of one set of support structure in multiple scenarios and has good economic efficiency.

[0023] Third, the temporary support structure for the reinforcing steel bars of the support beam of the present invention has fewer component materials compared with the traditional support system, which facilitates unified management on site. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but these are not intended to limit the scope of the invention.

[0032] Example 1:

[0033] like Figures 1-5 As shown, this invention discloses a temporary support structure for the reinforcing bars of a supporting beam. Specifically, the temporary support structure for the reinforcing bars of the supporting beam includes: an L-shaped limiting member 3, a supporting pipe 4, and two opposing columns 1. Both columns 1 are hollow structures. A strip-shaped hole is provided on the opposite side of each column 1 (this strip-shaped hole facilitates the insertion of the pin 2 into a suitable first insertion hole, and also facilitates observation of the positional relationship between the pier head and the limiting block 5 inside the column 1 when the L-shaped limiting member 3 is pulled out or rotated). The upper part of the opposite side of each column 1 has a first insertion hole spaced apart along the height direction of the column 1. Each column 1 has a first insertion hole, and the first insertion holes on the two columns 1 are correspondingly set (specifically, any first insertion hole on one column 1 can be found on the other column 1, and the two corresponding first insertion holes are located on the same horizontal line). Each column 1 has a second insertion hole spaced apart on both sides perpendicular to the extension direction of the support beam along the height direction of the column 1, and the second insertion holes on the two columns 1 are correspondingly set (specifically, any second insertion hole on one column 1 can be found on the other column 1, and the two corresponding second insertion holes are located on the same horizontal line). An L-shaped limiting member 3 is inserted into the second insertion hole. The aforementioned support pipe 4 is disposed between two columns 1, and the support pipe 4 is detachably fixed between the two columns 1 by a pin 2 inserted into the first insertion hole. The support pipe 4 serves as a top steel bar support for the support beam to place the top steel bar 6 of the support beam. A limiting block 5 is fixedly provided below each second insertion hole on the inner wall of the column 1. The L-shaped limiting member 3 includes a first rod and a second rod perpendicularly connected to the first rod. One end of the first rod is inserted into the second insertion hole, and the end of the first rod inserted into the column 1 is vertically provided with a pier. When the L-shaped limiting member 3 is rotated until the lower surface of the pier is located on the limiting block 5, the second rod is horizontally positioned, and the end of the second rod is located between the two columns 1. The second rod serves as a side steel bar support for the support beam to place the side steel bar of the support beam.

[0034] In an embodiment of the present invention, the first pin holes on the two columns 1 can be pre-reserved according to the common support beam height, protective layer thickness and steel bar size. Then, on site, according to the actual beam height, a suitable first pin hole is selected on the column 1 to insert the pin 2, so as to fix the support pipe 4 between the two columns 1 and make the support pipe 4 have a suitable elevation, so as to serve as the top steel bar support for the support beam.

[0035] In the embodiments of the present invention, the limiting principle of the L-shaped limiting member 3 is as follows: a second insertion hole is reserved at equal intervals on the side of the column 1, a limiting block is welded to the lower part of the second insertion hole on the inner side of the column 1, and a pier is provided at the end of the L-shaped limiting member 3 located on the inner side of the column 1, which can ensure that when the L-shaped limiting member 3 is rotated to the pier being located on the upper surface of the limiting block 5, the pier can limit the L-shaped limiting member 3 in the vertical direction; the L-shaped limiting member 3 is adjusted to the pier on the limiting block 5 by rotation and pulling, at which time the part of the L-shaped limiting member 3 located on the outer side of the column 1 can form a cantilever support state, which can be used as a side steel reinforcement support for the supporting beam; then, by rotation and pulling, the pier can be adjusted to outside the range of the limiting block 5, at which time the limiting steel reinforcement is rotated and reset.

[0036] In a preferred embodiment of the present invention, the column 1 is a steel column.

[0037] In a preferred embodiment of the present invention, the aforementioned pin 2 has a T-shaped structure to facilitate the insertion and removal of the pin 2. Specifically, the pin 2 is a pin.

[0038] In a preferred embodiment of the present invention, the L-shaped limiting member 3 is an L-shaped steel bar.

[0039] The supporting pipe 4 is a steel pipe, and the limiting block 5 is a steel plate. The materials are simple and readily available.

[0040] In a preferred embodiment of the present invention, the steel plate is welded and fixed to the inner wall of the column 1.

[0041] Example 2:

[0042] This embodiment discloses the assembly and use method of the above-mentioned temporary support structure for the reinforcing steel of the support beam, including the following steps:

[0043] Step S1: Based on the cross-sectional design dimensions of the support beam, the thickness of the top protective layer, and the dimensions of the top reinforcing bars of the support beam (i.e., the top longitudinal reinforcing bars of the support beam), select a suitable first insertion hole on the column and insert the pin. The height of the first insertion hole should meet the height requirements for installing the support pipe.

[0044] Step S2: After the columns on both sides of the beam section are installed in place, a support pipe is sleeved between the two pins to serve as a support for the top steel reinforcement of the beam.

[0045] Step S3: According to the position of the side reinforcement of the design support beam, adjust the L-shaped limiting piece on the column so that the pier head is placed on the limiting block, and the second member of the L-shaped limiting piece is set horizontally so that the second member serves as the side reinforcement support of the support beam (at this time, the L-shaped limiting piece is in the activated state).

[0046] Step S4: After all the steel bars of the support beam are tied using the temporary support structure of the support beam steel bars, adjust the L-shaped limiter to the second member to be set vertically (at this time, the L-shaped limiter is in the reset state), and remove the support pipe and column.

[0047] In summary, the temporary support structure for the reinforcing bars of the supporting beam disclosed in this invention, along with its assembly and usage method, can be pre-assembled at the processing site, requiring only simple positioning and connection on-site. This enables prefabricated construction and improves on-site construction efficiency. Furthermore, the L-shaped limiting component in this invention can achieve both "activated" and "reset" states. Multiple L-shaped limiting components can accommodate different design dimensions of the reinforcing bars on different beam sides. In addition, this temporary support structure for the reinforcing bars of the supporting beam has advantages such as clear structural stress, simple operation, and good economic and environmental benefits.
