Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of prefabricated concrete structure support, and in particular to a temporary support structure and method for heavier PC beams. Background Art
[0002] Prefabricated concrete structure, referred to as PC structure, refers to a concrete structure that is assembled and connected using prefabricated components as the main load-bearing components. In the traditional construction process of prefabricated concrete structures, PC beams are often directly erected on the walls at both ends or with steel tubes and square timbers erected at the bottom as support structures. However, with the continuous development of prefabricated buildings, the size and weight of PC beams are increasing, and construction conditions are becoming more and more demanding. If traditional support methods are used, the number of supports will need to be increased, but this will reduce the operating space below. If an attached lifting scaffold is used for construction, when the side beams are long and suspended in the air, the attached lifting scaffold needs to be disconnected. If traditional steel tubes and square timbers are used for support, the disconnected part of the attached lifting scaffold lacks protection, making operation difficult.
[0003] To this end, a temporary support structure and method for heavier PC beams have been researched and developed on the basis of existing technologies. The structure has a simple structure, safe support, easy operation, and can achieve the purpose of supporting heavier PC beams with a smaller number of supports. Therefore, when encountering a disconnected part of the attached lifting scaffolding, it is sufficient to set up supports within the protection range of the attached lifting scaffolding, and the structure can be reused, with a high utilization rate. Summary of the Invention
[0004] In view of the above situation, in order to overcome the defects of the existing technology, the present invention provides a temporary support structure and method for heavier PC beams, which solves the problem that the existing support method has limited support weight and lacks a safe operating environment when the side beams are long and suspended, thereby effectively expanding the scope of use.
[0005] Its technical solution is a temporary support structure and method for heavier PC beams, including anti-roll parts, stabilizers, support parts, fixing parts and out-of-plane supports. The anti-roll parts include square steel tubes, bolt rods, washers and nuts. The square steel tubes and bolt rods are welded and connected to prevent the PC beams from tipping over. The stabilizers include steel plates, limit angle steels, support angle steels, and connecting bolts to support the upper PC beams. The support parts include combined double rectangular tubes, I-beam columns, lead screws, adjusting nuts, round steel tubes, horizontal I-beams, steel pipe braces and steel pipe columns to support the upper components and transmit force to the lower structure. The fixing parts include 4 stiffening ribs, fixing steel plates, 4 long screws and corresponding nuts and 2 fastening channel steels to connect with the lower structure.
[0006] Furthermore, in the stabilizing member, the steel plate and the supporting angle steel are welded together, the limiting angle steel and the supporting angle steel are connected by connecting bolts, and long adjustable bolt holes are provided at both ends of the supporting angle steel to facilitate the passage of the connecting bolts, and the long adjustable bolt holes facilitate the adjustment of the position of the limiting angle steel, making the upper PC beam more stable.
[0007] Furthermore, in the support member, the combined double rectangular steel tube is welded to both sides of the I-beam column by two square steel tubes respectively, and the upper part is higher than the I-beam column by a certain distance, and a certain gap is formed between the two square steel tubes in the higher part. The bolt rod in the anti-roll member passes through the gap in the middle of the combined rectangular tube in the support member, and the bolt rod and the combined rectangular tube are fastened together by gaskets and nuts. The fastening length is determined according to the size of the supported PC beam.
[0008] Furthermore, in the support member, the I-beam column is welded to one end of the upper part of the horizontal I-beam, and together with the anti-tilt member, the PC beam is fixed to prevent the PC beam from overturning. The lower center of the horizontal I-beam is welded to the steel pipe column. The steel pipe column serves as a vertical supporting member. In order to ensure its stable force, steel pipe diagonal braces are set on both sides of the steel pipe column, and the upper part of the steel pipe diagonal brace is welded to the two ends of the horizontal I-beam respectively.
[0009] Furthermore, two holes are formed between the steel plate, the limiting angle steel and the supporting angle steel. The square steel tube in the anti-roll member passes through the hole at one end of the stabilizer and reaches the upper part of the horizontal I-beam in the support member, which facilitates the disassembly of the PC beam. The I-beam column in the support member passes through the hole at the other end of the stabilizer and forms a rectangular frame with the anti-roll member and the stabilizer. The PC beam is placed through the rectangular frame, ensuring the accurate position and good stability of the PC beam.
[0010] Furthermore, the lead screw, adjusting nut and round steel pipe form a jacking structure, which is two in total and is symmetrically arranged on both sides of the steel pipe column and welded to the steel pipe column. The jacking structure can be adjusted up and down to adjust the elevation.
[0011] Furthermore, a fixed steel plate and stiffening ribs are welded to the lower end of the steel pipe column. The steel pipe column is located at the center of the fixed steel plate. The four stiffening ribs are arranged in a "cross" shape. The fixed steel plate is connected to the lower completed structural member by a long screw, a nut, and a fastening channel steel. There are two fastening channel steels in total. Using two fastening channel steels can reduce the difficulty of construction. There is a long screw at each end of each fastening channel steel, for a total of four long screws.
[0012] Furthermore, one end of the out-of-plane support is obliquely supported on the existing concrete main structure through embedded parts, and the other end is connected to the steel pipe diagonal brace. The embedded parts need to be fixed in place in advance when pouring the concrete main structure. The out-of-plane support can prevent the support system from becoming unstable out of the plane.
[0013] The present invention also discloses a temporary support method for a heavy PC beam, using the temporary support structure for a heavy PC beam as described above, the method comprises the following steps:
[0014] The first step is to cast external support anchor embedded parts in the completed main structural components in advance to prevent out-of-plane instability.
[0015] The second step is to place fixed steel plates and fastening channel steels on the upper and lower parts of the completed lower components, and connect them together through long screws to form a clamp.
[0016] The third step is to install support parts on the upper part of the fixed steel plate, and simultaneously install out-of-plane supports, connecting them with fasteners to form a stable system.
[0017] In the fourth step, the support member passes through the hole at one end of the stabilizer, and the stabilizer is placed on the upper part of the support member. Then, the PC beam is placed on the upper part of the steel plate in the stabilizer.
[0018] The fifth step is to insert the square steel tube end of the anti-roll piece into the hole at the other end of the stabilizer, adjust the position of the limit angle steel and fix it so that it squeezes the PC beam, and the bolt rod in the anti-roll piece passes through the middle gap of the combined double rectangular tube and is fixed.
[0019] The technical effect of the present invention is that since the PC beam is placed on the stabilizer, the support area of the PC beam can be increased, and the lower part of the support adopts a steel pipe column and an inclined steel pipe design on both sides, which can withstand a larger load and reduce the risk of instability. Therefore, for larger and heavier PC beams, the support structure can be used to meet the safety and stability requirements with a smaller number of supports, thereby reducing the amount of high-altitude work and reducing safety hazards. At the same time, the lower working space is increased. Therefore, when encountering a disconnected part of the attached lifting scaffolding, it is sufficient to set up a support within the protection range of the attached lifting scaffolding. There are I-beam columns and square steel pipes on both sides of the upper part of the PC beam to ensure the accurate position of the PC beam. The lower part of the steel pipe column adopts two fastening channel steels and the clamps of the completed structural components for easy operation. One end of the anti-tilt member is fastened to the support member, and the other end is inserted into the hole of the stabilizer. It is easy to install and disassemble, and can be used in a turnover manner with a high utilization rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1
[0031] See also Figures 1 to 6A temporary support structure and method for heavier PC beams, comprising an anti-tilt member 1, a stabilizer 2, a support member 3, a fixing member 4, and an out-of-plane support 5. The out-of-plane support 5 is tilted on an existing concrete main structure 7 through an embedded member 6. The embedded member 6 needs to be fixed in place in advance when pouring the concrete main structure 7. The anti-tilt member 1 comprises a square steel tube 1-1, a bolt rod 1-2, a gasket 1-3, and a nut 1-4. The square steel tube 1-1 and the bolt rod 1-2 are welded to prevent the PC beam from tipping over. The stabilizer 2 comprises a steel plate 2-1, a limit Angle steel 2-2, supporting angle steel 2-3, connecting bolts 2-4 are used to support the upper PC beam. The support member 3 includes a combined double rectangular tube 3-1, an I-beam column 3-2, a screw 3-31, an adjusting nut 3-32, a round steel tube 3-33, a horizontal I-beam 3-4, a steel pipe brace 3-5 and a steel pipe column 3-6, which are used to support the upper components and transmit force to the lower structure. The fixing member 4 includes 4 stiffening ribs 4-1, a fixing steel plate 4-2, 4 long screws 4-4 and corresponding nuts 4-3 and 2 fastening channel steels 4-5, which are used to connect with the lower structure.
[0032] On the basis of the above embodiment, in the stabilizing member 2, the steel plate 2-1 and the supporting angle steel 2-3 are welded together, the limiting angle steel 2-2 and the supporting angle steel 2-3 are connected by connecting bolts 2-4, and long adjustable bolt holes 2-41 are provided at both ends of the supporting angle steel 2-3 to facilitate the passage of the connecting bolts 2-4. The connecting bolts 2-4 can move left and right in the adjustable bolt holes 2-41, thereby adjusting the position of the limiting angle steel 2-2 to make the upper PC beam more stable.
[0033] On the basis of the above embodiment, in the support member 3, the combined double rectangular steel tube 3-1 is composed of two 40mm×40mm square steel tubes welded to both sides of the I-beam column 3-2 respectively, and the upper part is higher than the I-beam column 3-2 by a certain distance, and a certain gap is formed between the two square steel tubes of the higher part. The bolt rod 1-2 in the anti-tilt member 1 passes through the gap in the middle of the combined rectangular tube 3-1 in the support member 3, and the bolt rod 1-2 and the combined rectangular tube 3-1 are fastened together by gaskets 1-3 and nuts 1-4. The fastening length is determined according to the size of the supported PC beam. Since there is no force requirement on the upper part, the bolt rod 1-2 and the combined rectangular tube 3-1 are connected by nuts 1-4 and gaskets 1-3, which is not only convenient for installation and disassembly, but also avoids material waste.
[0034] On the basis of the above embodiment, in the support member 3, the I-beam column 3-2 is welded to the upper left side of the horizontal I-beam 3-4, and together with the anti-tilt member 1, the left and right sides of the PC beam are fixed to prevent the PC beam from overturning. The lower center of the horizontal I-beam 3-4 is welded to the steel pipe column 3-6. The steel pipe column 3-6 serves as a vertical supporting member. In order to ensure its stable force, steel pipe diagonal braces 3-5 are arranged on both sides of the steel pipe column 3-6. The upper part of the steel pipe diagonal brace 3-5 is welded to the two ends of the horizontal I-beam 3-4 respectively.
[0035] On the basis of the above embodiment, two left and right holes are formed between the steel plate 2-1, the limiting angle steel 2-2 and the supporting angle steel 2-3. The square steel tube 1-1 in the anti-roll member 1 passes through the hole on the right side of the stabilizer 2 and is pushed to the upper part of the right side of the horizontal I-beam 3-4 in the support member 3, which is convenient for disassembling the PC beam. The I-beam column 3-2 in the support member 3 passes through the hole on the left side of the stabilizer 2 and is surrounded by the anti-roll member 1 and the stabilizer 2 to form a rectangular frame. The PC beam is placed through the rectangular frame, which ensures that the PC beam is accurately positioned, cannot shake left and right, and has good stability.
[0036] On the basis of the above embodiment, the lead screw 3-31, the adjusting nut 3-32 and the round steel pipe 3-33 form a supporting structure, which is two in total and is symmetrically arranged on both sides of the steel pipe column 3-6 and welded to the steel pipe column 3-6. The supporting structure can be adjusted up and down to adjust the elevation.
[0037] On the basis of the above embodiment, the lower end of the steel pipe column 3-6 is welded with a fixed steel plate 4-2 and a stiffening rib 4-1. The steel pipe column 3-6 is located at the center of the fixed steel plate 4-2, and the four stiffening ribs 4-1 are arranged in a "cross" shape. In this way, not only can the contact area between the steel pipe column 3-6 and the fixed steel plate 4-2 be increased, the supporting stability of the steel pipe column 3-6 is improved, but also steel can be saved. The fixed steel plate 4-2 is connected to the lower completed structural member by a long screw 4-4, a nut 4-3, and a fastening channel steel 4-5. There are two fastening channel steels 4-5 in total. Since two fastening channel steels 4-5 are used, each fastening channel steel 4-5 has a long screw 4-4 at both ends. During use, since the clamp is installed by bolt connection, it can be completed by one worker alone, which is convenient for installation and disassembly. In addition, the two fastening channel steels 4-5 and the four long screws 4-4 make the force more uniform, and the force is evenly transmitted to the lower completed structural member through the clamp structure.
[0038] Furthermore, one end of the out-of-plane support 5 is obliquely supported on the existing concrete main structure 7 through the embedded part 6, and the other end is connected to the steel pipe diagonal support 3-5. The embedded part 6 needs to be fixed in place in advance when pouring the concrete main structure 7. The out-of-plane support 5 can prevent the support system from becoming unstable out of the plane.
[0039] Example 2
[0040] Please continue reading Figures 1 to 6 This embodiment provides a construction method for a temporary support structure for a heavy PC beam, using the temporary support structure for a heavy PC beam as described in Example 1. The method includes the following steps:
[0041] The first step is to cast the external support anchor embedded parts 6 in advance in the completed main structural member 7 to prevent out-of-plane instability.
[0042] In the second step, a fixing steel plate 4-2 and a fastening channel steel 4-5 are placed on the upper and lower parts of the completed lower component, and are connected together by a long screw 4-4 to form a clamp.
[0043] The third step is to install the support member 3 on the upper part of the fixed steel plate 4-2, and simultaneously install the out-of-plane support 5, and connect them through fasteners to form a stable system.
[0044] In the fourth step, the support member 3 passes through the hole at one end of the stabilizer 2, and the stabilizer 2 is placed on the upper part of the support member 3, and then the PC beam is placed on the upper part of the steel plate 2-1 in the stabilizer 2.
[0045] The fifth step is to insert the square steel tube 1-1 end of the anti-roll component 1 into the hole at the other end of the stabilizer 2, adjust the position of the limit angle steel 2-2 and fix it so that it squeezes the PC beam, and the bolt rod 1-2 in the anti-roll component 1 passes through the middle gap of the combined double rectangular tube 3-1 and is fixed.
[0046] This embodiment provides a temporary support structure and method for heavier PC beams. Because the PC beam rests on a stabilizer 2, the support area for the PC beam can be increased. Furthermore, the lower portion of the support utilizes steel pipe columns 3-6 and diagonal steel pipes 3-5 on both sides, allowing it to withstand greater loads and reduce the risk of instability. Therefore, for larger and heavier PC beams, this support structure can achieve safety and stability requirements with fewer supports, thereby reducing the amount of overhead work and potential safety hazards while increasing the lower working space. Therefore, when encountering a disconnected portion of the attached lifting scaffold, supports can be established within the protection range of the attached lifting scaffold. I-beam columns 3-2 and square steel pipes 1-1 are located on either side of the upper portion of the PC beam, ensuring accurate positioning of the PC beam. The lower portion of the steel pipe column 3-6 is connected to the completed structural member with two fastening channels 4-5, facilitating operation. One end of the anti-tilt member 1 is fastened to the support member 3, while the other end slots into the hole in the stabilizer 2, making installation and removal easy and reusable, with a high utilization rate.
[0047] The present invention has been described in detail above by way of specific embodiments and examples, but these do not constitute any limitation to the scope of the present invention. Without departing from the principles of the present invention, those skilled in the art may make many variations and improvements, which should also be considered as the scope of protection of the present invention.
