Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a formwork fixing device for construction site use. Background Technology
[0002] Construction formwork is a temporary support structure, made according to design requirements, to shape concrete structures and components in the specified positions and geometric dimensions, maintain their correct positions, and bear the self-weight of the formwork and the external loads acting on it. The purpose of formwork engineering is to ensure the quality and safety of concrete engineering, accelerate the construction progress, and reduce project costs.
[0003] During construction, in order to ensure the stability of the formwork system, it is necessary to use a special formwork fixing device for reinforcement. In traditional construction, beam clamps are commonly used as the main fixing tool.
[0004] However, in practical applications, although beam clamps can effectively prevent formwork displacement and ensure the stability of concrete pouring, their complicated disassembly and assembly process significantly reduces the work efficiency of construction workers. Secondly, since multiple fixing points need to be set up and the spacing between each fixing device needs to be repeatedly measured and confirmed manually, this tedious installation process further affects the overall construction progress. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that the existing formwork fixing device has low disassembly and assembly efficiency and requires construction personnel to repeatedly measure the spacing during the installation process, thus affecting the construction efficiency. Therefore, a formwork fixing device for construction site is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A formwork fixing device for construction site includes a formwork and further includes: fixing plates, multiple sets of fixing plates connected end to end to form a frame structure, the frame structure encircling the formwork, one of the fixing plates being provided with a quick-release structure, wherein the multiple sets of frame structures are connected by positioning members and are vertically arranged on the formwork; and hinge members, arranged at the corners of two adjacent fixing plates, wherein when the hinge members are stretched to their limit position, the two adjacent fixing plates are perpendicular to each other.
[0008] For adjusting the rotation of the fixed plate, preferably, the hinge includes: a locking block, wherein the fixed plate has a groove and the locking block is slidably connected in the groove; and a connecting rod, both ends of which are rotatably connected to two adjacent locking blocks respectively.
[0009] To reset the fixed plate, a tension spring is further included, one end of which is fixedly connected to the slide groove, and the other end of the tension spring is fixedly connected to the locking block.
[0010] To further guide and limit the locking block, a T-shaped groove is provided in the slide groove, and a T-shaped block that is fixedly connected to the locking block is slidably connected in the T-shaped groove.
[0011] To further improve the quality of the fixed plate angle adjustment, the connecting rod is further designed to be arc-shaped.
[0012] To improve the template fixing effect, preferably, the fixing plate includes a vertical plate that abuts against the template, and a horizontal plate is fixedly connected to the side of the vertical plate away from the template, with positioning elements set on the horizontal plate.
[0013] To facilitate the control of the spacing between the fixing devices by the staff, the positioning component further includes a limiting frame and a positioning frame fixedly connected to the horizontal plate. A positioning rod is rotatably connected to the limiting frame, and the end of the positioning rod away from the limiting frame is engaged with the adjacent positioning frame.
[0014] To achieve rapid assembly of the fixing plates, one of the fixing plates is further comprising two separate structures. The quick-release structure is used to connect the two separate structures. The horizontal plate has a protrusion integrally formed, and the opposite horizontal plate has a slot in which the protrusion is inserted.
[0015] To further secure the mounting plate, mounting holes are provided on both the slot and the protrusion, into which bolt assemblies or pins are inserted.
[0016] To further improve the stability of the fixed plate locking installation, the bolt assembly includes a bolt inserted into a mounting hole, and the bolt is threaded with a nut that abuts against the fixed plate.
[0017] Compared with the prior art, this utility model provides a formwork fixing device for construction site use, which has the following advantages:
[0018] 1. This formwork fixing device for construction sites uses two separate fixing plates. After the protrusion of one fixing plate is inserted into the slot of the other fixing plate, the fixing plates can be quickly connected. Then, the two separate structures are fixed by bolt assembly, which can improve the stability of the fixing plates.
[0019] 2. This formwork fixing device for construction sites, through the setting of positioning parts, allows construction workers to unfold the pre-installed lower frame structure after the upper frame structure of the formwork is installed. The positioning rods are used to achieve precise docking of adjacent frame structures, which can automatically control the installation spacing of the frame structure, significantly improve construction efficiency, and reduce manual operation errors.
[0020] 3. This formwork fixing device for construction sites uses hinges to precisely adjust the angle of the fixing plate, ensuring that the inner side of the fixing plate is completely in contact with the formwork, significantly improving the positioning accuracy of the formwork. Furthermore, after the fixing plate is removed, a tension spring is used to reset and adjust the fixing plate to make it into a straight structure, which greatly facilitates the handling and carrying of construction personnel.
[0021] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model uses hinges to precisely adjust the angles of the five fixed plates, making them fit tightly with the template to form a stable frame structure. Combined with the quick-release structure, the frame structure is positioned, effectively improving the stability of the concrete pouring process. In addition, the positioning device enables convenient connection of the vertical frame structure, eliminating the traditional manual measurement of spacing and significantly improving construction efficiency.

[0030] Example:
[0031] Reference Figures 1-5 A formwork fixing device for construction sites includes a formwork and five fixing plates 1 connected end-to-end to form a frame structure that surrounds the formwork. One of the fixing plates 1 has a quick-release mechanism. When the quick-release mechanism releases the restriction on the fixing plate 1, the fixing plate 1 can be quickly disassembled. When the quick-release mechanism locks the fixing plate 1, the resulting frame structure can efficiently position the formwork. Two sets of frame structures are connected by positioning components and are vertically mounted on the formwork. A hinge is located at the corner of two adjacent fixing plates 1. When the hinge is stretched to its limit position, the two adjacent fixing plates 1 are perpendicular to each other, forming a 90-degree angle, which is used to fix the two adjacent formwork panels.
[0032] Specifically, the five fixed plates 1 are precisely angled by hinges to fit tightly with the template to form a stable frame structure. The quick-release structure is used to position the frame structure, which effectively improves the stability of the concrete pouring process. In addition, the positioning device enables convenient connection of the vertical frame structure, eliminating the traditional manual measurement of spacing and significantly improving construction efficiency.
[0033] The hinge includes: a locking block 3, a groove is provided on the fixing plate 1, the locking block 3 is slidably connected in the groove, a T-shaped groove is provided in the groove, and a T-shaped block is slidably connected to the locking block 3 in the T-shaped groove for guiding and limiting the locking block 3; and a connecting rod 31, both ends of which are rotatably connected to two adjacent locking blocks 3 respectively. The connecting rod 31 is arc-shaped to further improve the stability of the adjustment of the fixing plate 1.
[0034] It also includes a tension spring 32 with one end fixedly connected to the slide groove, and the other end of the tension spring 32 fixedly connected to the locking block 3.
[0035] Specifically, the angle of the fixing plate 1 is precisely adjusted by the hinge to ensure that the inner side of the fixing plate 1 is completely in contact with the template, which significantly improves the positioning accuracy of the template. Furthermore, after the fixing plate 1 is disassembled, the tension spring 32 is used to reset and adjust the fixing plate 1 so that it is in a straight line structure, which greatly facilitates the handling and carrying of construction personnel.
[0036] The fixed plate 1 includes a vertical plate that abuts against the template. A horizontal plate is fixedly connected to the side of the vertical plate away from the template. Positioning components are set on the horizontal plate. After the vertical plate and the horizontal plate are connected, their cross-section is T-shaped.
[0037] The positioning component includes a limiting frame 2 and a positioning frame 22 fixedly connected to the horizontal plate. The limiting frame 2 is fixedly installed on the top of the horizontal plate, and the positioning frame 22 is fixedly installed on the bottom of the horizontal plate. A positioning rod 21 is rotatably connected to the limiting frame 2, and the end of the positioning rod 21 away from the limiting frame 2 is engaged with the adjacent positioning frame 22.
[0038] Specifically, by setting up positioning components, after the installation of the upper frame structure of the template is completed, the construction workers will unfold the pre-installed lower frame structure and use positioning rods 21 to achieve precise docking of adjacent frame structures. This can automatically control the installation spacing of the frame structures, significantly improve construction efficiency, and reduce human error.
[0039] One of the fixing plates 1 consists of two separate structures. A quick-release structure is used to connect the two separate structures. The horizontal plate has a protrusion integrally formed, and the opposite horizontal plate has a slot. The protrusion is inserted into the slot, which is used to quickly assemble the two separate structures and improve installation efficiency.
[0040] Both the slot and the protrusion have mounting holes. After the protrusion is inserted into the slot, the mounting holes are vertically aligned. A bolt assembly or a pin is inserted into the mounting hole. Here, a bolt assembly is preferred. The bolt assembly includes a bolt 11 inserted into the mounting hole. A nut 12 that abuts against the fixing plate 1 is threaded onto the bolt 11.
[0041] Specifically, by using two separate fixing plates 1, the protrusion of one fixing plate 1 can be inserted into the slot of the other fixing plate 1 to achieve quick connection of the fixing plates 1. Subsequently, the two separate structures can be fixed by using a bolt assembly, which can improve the stability of the fixing plates 1 in use.
[0042] In the formwork fixing operation, the middle fixing plate 1 is first tightly attached to the formwork surface. Then, the construction workers simultaneously pull the two separate fixing plates 1. During this process, the movement of the fixing plate 1 will cause the locking block 3 to slide in the preset groove. When the locking block 3 slides, it will stretch the tension spring 32 and drive the connecting rod 31 to move accordingly. When the locking block 3 is adjusted to the designated position, a precise 90-degree angle will naturally be formed between the two adjacent fixing plates 1. In this way, the five fixing plates 1 are combined into a stable frame structure. The inner wall of this frame structure is in close contact with the formwork surface. At this time, the construction workers accurately insert the bolts 11 into the installation holes and use the tight connection between the nuts 12 and the bolts 11 to achieve a firm lock on the frame structure, thereby significantly improving the stability of the formwork support positioning.
[0043] The fixing of templates often requires the use of multiple such frame structures, and these frame structures need to be installed vertically. Taking a specific operation as an example: after the upper frame structure is installed, the construction workers only need to gently move the positioning rod 21 on the pre-installed fixing plate 1 to accurately snap its free end onto the positioning frame 22 of the installed frame structure. This can achieve automatic and accurate positioning of the spacing of the pre-installed fixing plates 1. This design saves the tedious step of manually measuring the spacing and greatly improves the construction efficiency. After the snapping operation is completed, the construction workers move the two fixing plates 1 in opposite directions to form a frame structure. Then, the bolts 11 and nuts 12 are used to securely position the frame structure.
[0044] When construction workers need to dismantle the formwork, they can remove the nut 12 on the bolt 11 and pull out the bolt 11 to quickly dismantle the frame structure. After dismantling, the frame structure will automatically return to a straight structure under the reset action of the tension spring 32, which greatly facilitates the handling and transportation work of construction workers.
[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
