Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and in particular to a support beam formwork reinforcement structure and reinforcement method. Background Technology
[0002] Currently, reinforced concrete support beam structures are widely used in deep foundation pit engineering. The cross-sectional dimensions of the support beams are relatively simple, generally consisting of main beams and secondary beams, and only side formwork is required during construction, which facilitates the application of modular formwork reinforcement systems. However, in actual construction, the support beam construction schedule is tight, and the working area is limited.
[0003] Current methods for reinforcing support beam formwork typically involve using double steel pipes and tie bolts. Specifically, depending on the height of the support beam, holes are drilled in the formwork to insert PVC pipes and tie bolts. The outer main purlins (double steel pipes) are secured with butterfly buckles, and the exposed tie bolt threads are tightened to achieve overall formwork reinforcement. However, this method can damage the formwork and the concrete of the support beam itself (leaving holes). Summary of the Invention

Detailed Implementation
[0033] 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.
[0034] Example 1:
[0035] like Figure 1 As shown, this invention discloses a support beam template reinforcement structure. The support beam template includes two beam side templates 2 installed on a cushion layer, and the two beam side templates 2 are respectively located on both sides of the extension direction of the support beam 1. Specifically, the support beam template reinforcement structure includes: a steel beam 4, a steel main purlin 5, and an adjustable support frame 6. The steel beam 4 is set on the top of the two beam side templates 2, and the length direction of the steel beam 4 is perpendicular to the surface of the beam side template 2. Purlin through holes 41 are provided at intervals along the length direction of the steel beam 4 at both ends. Steel main purlins 5 are respectively provided on both sides of the two beam side templates 2, and the steel main purlins 5 are installed through the purlin through holes 41. The adjustable support frame 6 includes a telescopic rod, one end of which is rotatably connected to one end of the steel beam 4, and the other end of which is fixed to the steel main purlin 5.
[0036] Specifically, the adjustable support frame 6 includes a pair of ear plates, a first pin 62, a telescopic rod, and a second pin 67. The ear plates are fixed below the end of the steel beam 4. The top end of the telescopic rod is located between the two ear plates 61 of the ear plate pair. The first pin 62 passes through the ear plate pair and the top end of the telescopic rod to rotatably connect the top end of the telescopic rod between the two ear plates 61 of the ear plate pair. Multiple pin holes are provided on the main steel purlin 5 along the length of the main steel purlin 5. The bottom end of the telescopic rod is fixed to the main steel purlin 5 by the second pin 67. The aforementioned telescopic rod includes a first rod, a threaded sleeve 66, and a second rod. The first rod is rotatably connected to a first pin 62, and the second rod is fixedly connected to the main steel purlin 5 via a second pin 67. Both the first and second rods have external threads 65 at their opposite ends. The first and second rods are respectively connected to the two ends of the threaded sleeve 66 via the external threads 65, and the directions of the external threads 65 on the first and second rods are opposite. In this embodiment, the adjustable support frame 6 utilizes the purlin through-holes 41 on the steel beam 4 to meet the requirements of different beam widths; and by using the purlin through-holes 41 on the steel beam 4 for selection, and then using the rotation of the threaded sleeve 66 to adjust the length of the support frame, it meets the requirements of different beam heights. Therefore, it is applicable to environments with different beam widths and heights, and has good economic and environmental benefits.
[0037] In a preferred embodiment of the present invention, both the first and second rods include a steel sheet 63 and a steel pipe 64. The steel pipe 64 is provided with external threads. The steel sheet 63 of the first rod is rotatably connected to the first pin 62, and the steel sheet 63 of the second rod is fixedly connected to the main steel purlin 5 by the second pin 67. In this first and / or second rod, the steel sheet 63 and the steel pipe 64 are welded together.
[0038] The specific principle of the aforementioned adjustable support frame is as follows: Two ear plates 61 are welded to the bottom of the steel beam 4; the steel plate 63 is connected to the ear plates 61 using the first pin 62. This allows for free adjustment of the adjustable support frame angle; the steel plate 63 is welded to the steel pipe 64 to form a whole, and the outer surface of the other side of the steel pipe 64 is threaded; the upper and lower steel pipes are connected to a whole using a threaded sleeve 66 with internal threads, and the length of the adjustable support frame is adjusted by rotating the threaded sleeve 66; the lower steel plate 63 is connected and fixed to the pin hole on the main steel purlin 5 using the second pin 67.
[0039] It should be noted that the steel fittings in this application can all be replaced with lightweight and high-strength aluminum alloy components; the above-mentioned threaded sleeves can be replaced with socket-type inserts; the steel purlins can be replaced with square column buckles that are already widely used in the market for reinforcing frame column formwork, which does not affect the purpose of this invention.
[0040] In a preferred embodiment of the present invention, timber purlins 3 are provided on both sides of the two beam side formwork 2, and steel main purlins 5 are provided close to the timber purlins 3 on the outside of the timber purlins 3.
[0041] In a preferred embodiment of the present invention, a tensioning rod 7 is provided between the steel purlins 5 located outside the two beam side templates 2, and the two ends of the tensioning rod 7 respectively abut against the side walls of the two steel purlins 5 to tighten the two steel purlins 5. Specifically, the tensioning rod 7 is a wooden beam.
[0042] In a preferred embodiment of the present invention, two rows of purlin through holes 41 are respectively arranged at both ends of the steel beam 4, and the two rows of purlin through holes 41 are staggered, such as... Figure 5 As shown, the purlin perforations 41 of the two rows are adjacent to each other. Any purlin perforation 41 in one row overlaps with any purlin perforation 41 in the other row, but not completely, so that the main steel purlin 5 can select a purlin perforation 41 that is closer to the beam side formwork 2.
[0043] Example 2:
[0044] This embodiment discloses a method for reinforcing support beam formwork, based on the support beam formwork reinforcement structure in Embodiment 1 above. Specifically, the method includes the following steps:
[0045] Step S1: After the beam side formwork and timber are installed in place, adjust the top elevation of the beam side formwork and place the steel beam on top of the beam side formwork.
[0046] Step S2: Based on the spacing between the outer walls of the two beam side formworks, insert the main steel purlins into the steel beam through the purlin holes.
[0047] Step S3: Install an adjustable support frame between the steel beam and the main steel purlin, and use the adjustable support frame to support and reinforce the side formwork of the beam.
[0048] Step S4: Tighten the top of the support beam between the main steel purlin and the steel beam using a jacking rod.
[0049] In summary, the support beam formwork reinforcement structure and method disclosed in this invention have the advantages of simple and clear structural stress, simple operation, readily available materials, and the ability to achieve prefabricated construction. It does not require pre-drilled tie bolt holes, thereby reducing the destructive impact on the support beam structure itself. It is suitable for reinforcement of support beam formwork with different beam widths and heights, has good energy-saving and efficiency-enhancing effects, and has good economic and environmental benefits.
