Description

Technical Field

[0001] This utility model belongs to the field of building formwork support technology, and more specifically, it relates to an angle-adjustable building formwork support top. Background Technology

[0002] Formwork support tops are key adjustable components used in formwork support systems during building construction. Their main function is to precisely adjust the height and flatness of the formwork and transfer the load to the lower support structure, ensuring the stability and dimensional accuracy of the formwork during concrete pouring. Most existing support tops are fixed. When dealing with non-horizontal or non-vertical concrete structures (such as sloping roofs, inclined beams, curved walls, stair treads, etc.), angle-adjustable support tops are needed to adapt to the tilt angle requirements of complex structures and ensure that the formwork is precisely matched with the designed slope and curvature.

[0003] Chinese patent publication number "CN222045046U" discloses an angle-adjustable template support top, including a screw rod, a support plate, a connector, and a positioning component. The support plate is located on top of the screw rod and is hinged to the screw rod via the connector. The positioning component is located between the support plate and the screw rod, including a first mating part and a second mating part. The support plate and the screw rod are hinged together via the connector, enabling free adjustment of the support plate angle. This is suitable for construction scenarios where the casting template and the bottom support system are not perpendicular, making adjustment simple and improving construction efficiency. By setting the positioning component, the support plate can be positioned after the angle is adjusted to ensure its stability and thus the effectiveness of the support.

[0004] In later use, the device also had the following problems: the adjustment and locking operations were very cumbersome, requiring frequent disassembly of bolts and pins to complete one adjustment of the tray angle, resulting in low installation efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an angle-adjustable building formwork support top support. By setting the support top support, the angle of the tray can be adjusted after pulling the tray upward. After the adjustment is in place, the tray is pressed down, so that the inclined teeth squeeze the end tooth retaining rings on both sides, thereby fixing the tilt angle of the fixing components and the tray and completing the adjustment of the tray support angle.

[0006] An adjustable-angle building formwork support top includes a hollow steel pipe with a support base at the bottom. The support base includes a pressure plate, and a lower screw is fixedly connected to the top of the pressure plate. An adjusting nut is threaded onto the lower screw. A support top is provided at the top of the hollow steel pipe, and the support top includes an upper screw. Another set of adjusting nuts is threaded onto the upper screw. An installation frame is fixedly connected to the top of the upper screw. A limit slide frame is slidably connected to the inner wall of the installation frame. Two sets of end toothed blocks are slidably connected inside the limit slide frame. An opening is fixedly provided in the middle of the limit slide frame. A fixing component is slidably connected to the opening. A tray is fixedly connected to the top of the fixing component. Side baffles are fixedly connected to both sides of the top of the tray. Single-tube bayonets are fixedly provided on the side baffles.

[0007] Preferably, the upper side wall of the mounting bracket is fixedly provided with a shaft hole, a pin is slidably contacted in the shaft hole, a B-type pin is installed at the tail of the pin, an annular groove is fixedly provided below the shaft hole, an end tooth retaining ring is fixedly connected inside the annular groove, and a limit countersunk hole is fixedly provided in the middle of the bottom of the mounting bracket.

[0008] Preferably, the fixing component includes a fixing column, a side support column extending outward from the upper part of the fixing column, a straight groove fixedly opened on the side support column, multiple sets of grooves fixedly opened on the lower side wall of the fixing column, and an avoidance support column fixedly connected to the bottom of the fixing column.

[0009] Preferably, the outer end of the end tooth block is fixedly connected with a helical tooth, and the inner end of the end tooth block is fixedly provided with a notch, and the top of the notch is fixedly provided with a pressing end face.

[0010] Preferably, the extrusion end face cooperates with the fixed post. When the fixed post presses the extrusion end face downward, the end tooth block moves outward, so that the helical teeth contact the end tooth retaining ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting a support top, pulling the tray upwards causes the fixing column to disengage from the extrusion notch, and the oblique teeth stop extruding the end tooth retaining ring, thus allowing the tray angle to be adjusted. After adjustment, pressing the tray down causes the oblique teeth to extrude the end tooth retaining rings to both sides, fixing the tilt angle of the fixing components and the tray, and completing the adjustment of the tray support angle. 2. By setting limit countersunk holes and avoidance support columns, when the pallet supports the horizontal template, the avoidance support columns are inserted into the limit countersunk holes, which further improves the stability of the pallet support in addition to locking the limit slide frame. 3. By setting a fixing component and an end toothed block, when the fixing column slides down, the end toothed block is pushed outward to lock the current position of the limiting slide frame, and the tilt angle of the tray is fixed. When the fixing column is pulled up, the end toothed block is allowed to slide inward and retract into the limiting slide frame, and the angle of the tray is restored to a freely adjustable state.

[0014] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] like Figure 1 , Figure 2 and Figure 3 As shown, an angle-adjustable building formwork support includes a hollow steel pipe 3. A support base 1 is provided at the bottom of the hollow steel pipe 3. The support base 1 includes a pressure plate 101. A lower screw 102 is fixedly connected to the top of the pressure plate 101, and an adjusting nut 2 is threaded onto the lower screw 102. The support base 1 provides bottom support for the entire building formwork support system. A support top 4 is provided at the top of the hollow steel pipe 3. By setting the support top 4, pulling the tray 7 upward causes the fixing column 801 to disengage from the extrusion notch 902, and the inclined teeth 901 stop extruding the end tooth retaining ring 402D. This allows the angle of the tray 7 to be adjusted. After adjustment, pressing down on the tray 7 causes the inclined teeth 901 to press the end tooth retaining ring 402D to both sides, fixing the tilt angle of the fixing component 8 and the tray 7, thus completing the adjustment of the tray 7's support angle.

[0016] like Figure 4 , Figure 5 and Figure 9 As shown, the support top support 4 includes an upper screw 401, which is threadedly connected to another set of adjusting nuts 2. By rotating the adjusting nuts 2, the length of the support top support 4 extending upward from the hollow steel pipe 3 can be adjusted, thereby completing the support for the building formwork. A mounting bracket 402 is fixedly connected to the top of the upper screw 401. A limiting slide frame 5 is slidably connected to the inner wall of the mounting bracket 402. The limiting slide frame 5 can swing and slide inside the mounting bracket 402, thereby adjusting the tilt angle of the tray 7.

[0017] The limiting slide frame 5 has two sets of end toothed blocks 9 slidably connected inside. The limiting slide frame 5 has an opening 501 fixed in the middle. The opening 501 is slidably connected to the fixing component 8. By setting the fixing component 8 and the end toothed blocks 9, when the fixing column 801 slides down, the end toothed blocks 9 are pushed outward, so that the end toothed blocks 9 contact and cooperate with the end toothed ring 402D to lock the current position of the limiting slide frame 5 and fix the tilt angle of the tray 7. When the fixing column 801 is pulled up, it avoids the cooperation between the support column 803 and the end toothed blocks 9, allowing the end toothed blocks 9 to slide inward and retract into the limiting slide frame 5. The end toothed blocks 9 and the end toothed ring 402D can no longer maintain the squeezing contact, and the angle of the tray 7 returns to a state of free adjustment. The top of the fixing component 8 is fixedly connected to the tray 7. By setting the side baffles 701 on the top of the tray 7, it is possible to support the timber or two sets of steel pipes, thereby fixing the building formwork. Alternatively, a single pipe clamp 702 can be used to fix and limit a single steel pipe, which can both complete the support operation and ensure the stability of the support. The top two sides of the tray 7 are fixedly connected to the side baffles 701, and the side baffles 701 are fixedly provided with single pipe clamps 702.

[0018] like Figure 8 As shown, the upper side wall of the mounting bracket 402 is fixedly provided with a shaft hole 402A, and a pin 6 is slidably contacted on the shaft hole 402A. By setting the pin 6, the fixing component 8 can be installed and disassembled. In order to ensure the stability of the pin 6 installed on the pin hole, a type B pin 10 is used to insert into the opening at the tail of the pin 6. The type B pin 10 is easy for workers to insert and remove by hand, thus facilitating the disassembly and assembly of the fixing component 8.

[0019] like Figure 7 As shown, a type B pin 10 is installed at the tail of the pin 6. Conventional pins require workers to use pliers or other tools to bend and clamp them in place. An annular groove 402C is fixedly opened below the shaft hole 402A. An end tooth retaining ring 402D is fixedly connected inside the annular groove 402C. The end tooth retaining ring 402D is completely located inside the annular groove 402C and will not obstruct the swing of the limiting slide frame 5. A limiting countersunk hole 402B is fixedly opened in the middle of the bottom of the mounting frame 402. By setting the limiting countersunk hole 402B and the avoidance support column 803, when the pallet 7 supports the horizontal template, the avoidance support column 803 is inserted into the limiting countersunk hole 402B, which, in addition to locking the limiting slide frame 5, further improves the stability of the pallet 7 support.

[0020] like Figure 6 As shown, the fixing component 8 includes a fixing column 801, with a side support column 802 extending outward from the upper part of the fixing column 801. The two sides of the side support column 802 slide in contact with the inner wall of the mounting bracket 402, providing support for the fixing column 801 and increasing the stability of the fixing column 801. A straight slot 802A is fixedly opened on the side support column 802, and a pin 6 slides in contact with the straight slot 802A. After the pin 6 is inserted, the fixing component 8 is limited. By setting the straight slot 802A and the opening 501, the fixing column 801 is only allowed to move along the axial direction of the opening 501, and the stroke of the movement is limited by the straight slot 802A. Multiple sets of grooves 801A are fixedly provided on the lower side wall of the fixed post 801. Lubricant can be applied to the bottom of the fixed post 801 to reduce the friction between the fixed post 801 and the end toothed block 9, making it easier for the fixed post 801 to press down and lock the limiting slide frame 5. The design of the grooves 801A facilitates the storage of lubricant and reduces the contact area between the fixed post 801 and the end toothed block 9, thereby reducing frictional resistance to a certain extent. An avoidance support post 803 is fixedly connected to the bottom of the fixed post 801. The diameter of the avoidance support post 803 is smaller than the diameter of the fixed post 801, so that when the fixed post 801 moves upward, the avoidance support post 803 contacts and engages with the end toothed block 9, allowing the end toothed block 9 to retract into the limiting slide frame 5, disengage from the end toothed ring 402D, and return to a free adjustment state.

[0021] like Figure 10 As shown, the outer end of the end tooth block 9 is fixedly connected with a helical tooth 901. The tooth shape of both the end tooth retainer 402D and the helical tooth 901 is triangular. When the helical tooth 901 is subjected to outward extrusion force and maintains contact and engagement with the end tooth retainer 402D, the position of the limiting slide frame 5 is locked. When the helical tooth 901 loses the outward extrusion force, although the helical tooth 901 and the end tooth retainer 402D remain in contact, as the limiting slide frame 5 swings, the triangular tooth shape will cause the helical tooth 901 to be pushed inward, and the two can no longer maintain the engagement state. The inner end of the end tooth block 9 is fixedly provided with a notch 902, and the top of the notch 902 is fixedly provided with an extrusion end face 903.

[0022] The extrusion end face 903 cooperates with the fixed post 801. When the fixed post 801 extrudes the extrusion end face 903 downward, the end tooth block 9 moves outward, so that the helical tooth 901 contacts the end tooth retaining ring 402D.

[0023] The usage process is as follows: Figure 11 and Figure 12 As shown: 1. Insert the lower screw 102 into the hollow steel pipe 3 from the bottom, rotate the adjusting nut 2 on the lower screw 102 to adjust the height of the hollow steel pipe 3, and insert the upper screw 401 into the hollow steel pipe 3 from the top; 2. Lift the tray 7 upwards, and the fixing column 801 moves upwards along the opening 501 to avoid the support column 803 from engaging with the end tooth block 9. After rotating the tray 7 to a suitable angle, press the tray 7 down, and the fixing column 801 moves downwards along the opening 501. The bottom of the fixing column 801 contacts and presses outwards the pressing end face 903, and the helical tooth 901 contacts and locks the end tooth retainer 402D to fix the current tilt angle of the tray 7. 3. If further angle adjustments are needed, simply lift tray 7 upwards again to make adjustments, and press tray 7 down to fix the current angle; 4. When disassembly is required, pull out the B-type pin 10, remove the pin 6, take out the fixing component 8 and tray 7, apply grease to the groove assembly 801A, and then reinstall it for continued use. 5. When the inclined building formwork does not need to be supported, after adjusting the pallet 7 to a horizontal position, press it down. Not only can the limiting slide frame 5 and the end tooth block 9 fix the pallet 7, but as the fixing column 801 is pressed down, the avoidance support column 803 at the bottom of the fixing column 801 is inserted into the limiting countersunk hole 402B to further fix the pallet 7 and increase the support stability in the horizontal position.

[0024] This invention, by setting a supporting top support 4, allows the tray 7 to be pulled upwards, causing the fixing post 801 to disengage from the extrusion notch 902. The helical teeth 901 then stop extruding the end tooth retaining ring 402D, thus allowing the angle of the tray 7 to be adjusted. After adjustment, pressing down on the tray 7 causes the helical teeth 901 to press the end tooth retaining ring 402D to both sides, fixing the tilt angle of the fixing component 8 and the tray 7, completing the adjustment of the tray 7's support angle. By setting a limiting countersunk hole 402B and a clearance support post 803, when the tray 7 is in a horizontal position... When the plate is supported, the support column 803 is inserted into the limiting countersunk hole 402B, which not only locks the limiting slide frame 5, but also further improves the stability of the pallet 7 support. By setting the fixing component 8 and the end tooth block 9, when the fixing column 801 slides down, the end tooth block 9 is pushed outward to lock the current position of the limiting slide frame 5, and the tilt angle of the pallet 7 is fixed. When the fixing column 801 is pulled up, the end tooth block 9 is allowed to slide inward and retract into the limiting slide frame 5, and the angle of the pallet 7 returns to a state of free adjustment.
