Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a building support frame for building engineering. Background Technology

[0002] In the concrete pouring construction of building projects, the building support frame is the core temporary load-bearing system that ensures construction safety and concrete forming quality. Its core function is not only to accurately bear the self-weight of the newly poured concrete, the dynamic live loads of personnel operation and vibration equipment during construction, but also to stably support the entire weight of the formwork system, ensuring that the concrete maintains its preset shape and structural stability before reaching the design strength. It is mainly divided into two categories: formwork support system and temporary auxiliary support. This type of support frame is used in conjunction with the formwork system and directly determines the pouring quality and construction safety. The building support frame can provide stable and reliable temporary load-bearing guarantee for concrete pouring construction.

[0003] Chinese Patent Publication No. CN222949513U discloses a building support frame for construction engineering, including a support component, an adjustment component, and two guide rods. The support component includes two support plates, both of which are hinged to the same connecting plate via pins. Both support plates have through slots. In this invention, a forward-rotating operating block and a threaded rod rotate to move a movable block toward the connecting plate. The movable block, through the connecting rod, causes the two support plates to rotate around the connecting plate. This design allows the support frame, composed of support plates and connecting plates, to flexibly adapt to columns and beams at different angles and achieve stable connection and fixation. This effectively meets the diverse structural construction needs in construction engineering, greatly improves the applicability of the support frame in various construction scenarios, and provides reliable protection for the construction of complex building structures.

[0004] However, the present invention has the following problems in actual use; When the existing equipment is in use, the support components at the rear can only support and limit the upper part of the frame. When cement is poured into the frame, the weight of the newly poured cement will cause the lower part of the frame to bear a concentrated load. Without corresponding support and protection, the lower part of the frame is prone to tilting and deformation due to excessive stress. In severe cases, it may even cause structural damage, which not only affects the forming accuracy of the cast components, but also easily causes construction safety hazards. Utility Model Content

[0005] (a) Technical problems to be solved To overcome the aforementioned deficiencies of the prior art, this utility model provides a building support frame for construction engineering. It solves the problem mentioned in the background art that when existing equipment is used, the rear support components can only support and limit the upper end of the frame. When cement is poured into the frame, the self-weight of the newly poured cement will cause the lower end of the frame to bear a concentrated load. Without corresponding support and protection, the lower end of the frame is prone to tilting and deformation due to excessive stress, and in severe cases, structural damage may even occur. This not only affects the forming accuracy of the cast components, but also easily causes construction safety hazards.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a building support frame for construction engineering, comprising a frame plate, a positioning frame bolted to one side of the frame plate, a support rod detachably connected inside the positioning frame, a lower support rod detachably connected to the lower end of the support rod, one side of the lower support rod detachably connected to the outer surface of the frame plate, a middle support rod fixedly connected to the upper end of the lower support rod, and one end of the middle support rod detachably connected to the outer surface of the frame plate.

[0007] Preferably, a sliding groove for positioning is provided on one side of the frame plate, and a connecting block for limiting the position is fixedly connected to the other side of the frame plate.

[0008] Preferably, a connecting rod for positioning is inserted into one side of the support rod, and one end of the connecting rod passes through the support rod and the positioning frame in sequence.

[0009] Preferably, one end of the connecting rod is threaded with a nut for fixing, and the outer surface of the nut is provided with friction texture for anti-slip.

[0010] Preferably, positioning plates are fixedly connected to both sides of the positioning frame, and bolts for fixing are inserted into one side of the positioning plate.

[0011] Preferably, the bottom of the support rod is fixedly connected to a mounting plate for limiting the position, and the upper end of the mounting plate is inserted with an anchor for limiting the position.

[0012] Preferably, a fastening post for fixing is inserted into the outer surface of one end of the central support rod, and one end of the fastening post passes through one side of the central support rod and is inserted into the interior of the frame plate.

[0013] Preferably, a threaded post for fixing is inserted into the outer surface of one end of the lower support rod, and one end of the threaded post passes through one side of the lower support rod and is threaded into the inside of the frame plate.

[0014] (III) Beneficial Effects This utility model provides a building support frame for construction engineering, which has the following beneficial effects: The building support frame used in this construction project, through the coordinated arrangement of support rods and frame panels, can more conveniently bear the self-weight of cement and construction loads transmitted by the frame panels when workers use it. It transfers vertical forces downward to the foundation or lower load-bearing structure, preventing the frame panels from sinking or deforming due to excessive vertical stress. At the same time, the central support rod can form a lateral tension force in the middle of the frame, balancing the lateral load in the middle of the frame panel during cement pouring, preventing the frame panel from bulging or deforming in the middle due to uneven stress at the top and bottom. It also connects the lower support rod and the frame panel, so that the support force forms a transition in the middle of the frame, reducing stress concentration during load transfer. The setting of the lower support rod can also offset the lateral pressure on the lower end of the frame panel during cement pouring, preventing the lower end of the frame from tilting due to stress concentration.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Example 1; Please see Figures 1 to 4This utility model provides a technical solution: a building support frame for construction projects, mainly used in concrete pouring scenarios. It includes a frame plate 1, with a positioning frame 2 bolted to one side of the frame plate 1. A support rod 3 is detachably connected inside the positioning frame 2. A connecting rod 8 for positioning is inserted into one side of the support rod 3. One end of the connecting rod 8 passes through the support rod 3 and the positioning frame 2, and a nut 9 for fixing is threaded onto one end of the connecting rod 8. The outer surface of the nut 9 has anti-slip friction textures. A lower support rod 4 is detachably connected to the lower end of the support rod 3, and one side of the lower support rod 4 is detachably connected to the outer surface of the frame plate 1. The upper end of the lower support rod 4 is fixedly connected to the middle support rod 5. One end of the middle support rod 5 is detachably connected to the outer surface of the frame plate 1. The support rod 3 and the positioning frame 2 are rigidly connected by the connecting rod 8 to prevent the support rod 3 from sliding relative to the positioning frame 2 when under force, ensuring stable force transmission between the two and avoiding instability of the support rod 3 due to loose connection. With the help of the nut 9, the connecting rod 8 is firmly fixed to the support rod 3 and the positioning frame 2 by tightening, further strengthening the connection strength between the two. The friction texture on the outer surface can increase the friction of the hand or tool, making it easy to tighten during installation, while preventing loosening due to vibration during use and ensuring connection reliability. Example 2; Please see Figures 1 to 4 The frame plate 1 has a positioning groove 6 on one side, and a limiting connecting block 7 is fixedly connected to the other side of the frame plate 1. Positioning plates 10 are fixedly connected to both sides of the positioning frame 2, and bolts 11 for fixing are inserted into one side of the positioning plates 10. The groove 6 is located on one side of the frame plate 1, providing adjustable positioning space for the connection between the frame plate 1 and other templates or other auxiliary components. This facilitates adjusting the installation position of the frame plate 1 according to the size of the cast component, improving the adaptability of the frame plate 1. At the same time, it can also serve as a positioning reference to ensure the flatness when multiple frame plates 1 are spliced, and avoid the casting accuracy being affected by positional deviations at the splicing point. With the help of the connecting block 7, it mainly serves to limit and guide the splicing. When multiple frame plates 1 need to be used in combination, the connecting block 7 can cooperate with the sliding groove 6 of the adjacent frame plate 1 to limit the lateral and longitudinal displacement of the frame plate 1, ensure that the frame plate 1 is aligned as a whole after splicing, and prevent the component size deviation caused by the misalignment of the frame plate 1 during the pouring process. The matching of the positioning plate 10 and the bolt 11 is the core connecting part between the positioning frame 2 and the frame plate 1. The positioning frame 2 is firmly fixed on the frame plate 1 through the thread engagement, ensuring that the positioning frame 2 does not shift when bearing the load transmitted by the support rod 3, and providing a stable installation foundation for the support rod 3. Example 3; Please see Figures 1 to 4The bottom of the support rod 3 is fixedly connected to a mounting plate 12 for limiting the position. An anchor 13 for limiting the position is inserted into the upper end of the mounting plate 12. A fastening post 14 for fixing is inserted into the outer surface of one end of the middle support rod 5. One end of the fastening post 14 passes through one side of the middle support rod 5 and is inserted into the inside of the frame plate 1. A threaded post 15 for fixing is inserted into the outer surface of one end of the lower support rod 4. One end of the threaded post 15 passes through one side of the lower support rod 4 and is threaded into the inside of the frame plate 1. By using the mounting plate 12, the contact area between the support rod 3 and the foundation or substructure is increased, which can evenly transfer the vertical load borne by the support rod 3 to the ground, preventing the lower end of the support rod 3 from sinking into the foundation due to excessive pressure, thus preventing the frame plate 1 from sinking. At the same time, it provides an installation position for the anchor nail 13, realizing the limiting and fixing of the support rod 3. The middle support rod 5 is detachably connected to the frame plate 1 by the fastening column 14. The relative displacement between the middle support rod 5 and the frame plate 1 is limited by the physical plug-in action, ensuring that the middle support rod 5 can stably bear the lateral load transmitted by the frame plate 1. At the same time, it is easy to disassemble later, improving the reusability of the frame plate 1. By using the threaded column 15, the lower support rod 4 is rigidly fixed to the frame plate 1, ensuring that the lower support rod 4 does not detach from the frame plate 1 when bearing lateral pressure. The threaded connection method facilitates the adjustment of the position of the lower support rod 4 during installation, while ensuring the connection strength and preventing the lower support rod 4 from loosening due to stress.

[0019] In this invention, the working steps of the device are as follows: First, place the frame plate 1 in position according to the baseline. Place the positioning bracket 2 against one side of the frame plate 1, ensuring the positioning plates 10 on both sides of the positioning bracket 2 are flush with the surface of the frame plate 1. Insert the bolts 11 into the pre-drilled holes in the positioning plates 10, passing through them and threadedly connecting them to the frame plate 1. Tighten the bolts 11 with a wrench to ensure the positioning bracket 2 is firmly fixed to the frame plate 1 without loosening or displacement. Insert the support rod 3 into the internal installation space of the positioning bracket 2 and adjust its verticality. Insert the connecting rod 8 into the pre-drilled hole on one side of the support rod 3, ensuring one end of the connecting rod 8 passes through both the support rod 3 and the positioning bracket 2. Place a nut 9 on the protruding end of the connecting rod 8, using the friction texture on the outer surface of the nut 9 to increase friction. Tighten the nut 9 with a wrench to achieve a rigid connection between the support rod 3 and the positioning bracket 2, preventing relative sliding. Simultaneously, place one end of the lower support rod 4 against the outer surface of the frame plate 1, and align the other end with the pre-drilled interface at the lower end of the support rod 3. Insert the threaded post 15 into the pre-drilled hole at one end of the lower support rod 4, passing through it. 4. Connect the lower support rod 4 to the internal thread of the frame plate 1, adjust the angle of the lower support rod 4, tighten the threaded post 15 to fix the lower support rod 4, align one end of the middle support rod 5 with the reserved slot on the outer surface of the frame plate 1, and fit the other end with the fixing point at the upper end of the lower support rod 4. Insert the fastening post 14 into the reserved hole at one end of the middle support rod 5, pass through the middle support rod 5 and then insert it into the frame plate 1. Tap the fastening post 14 to make it fully locked, completing the installation of the middle support rod 5. If the concrete pouring component is large and multiple frame plates 1 need to be spliced, the corresponding... When adjacent frame plates 1 are brought close together, the connecting block 7 of one frame plate 1 is embedded into the groove 6 of another frame plate 1. The position of the frame plate 1 is adjusted along the groove 6 to ensure that the splice is flat and aligned. The mounting plate 12 at the bottom of the support rod 3 is completely in contact with the ground. If there is a gap, a thin steel plate can be inserted to level it. The anchor nail 13 is inserted from the reserved hole at the top of the mounting plate 12. The anchor nail 13 is hammered to make one end of the anchor nail 13 penetrate into the foundation or the lower load-bearing structure, thereby limiting and fixing the support rod 3 and improving its anti-overturning ability.
