Description

Technical Field

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

[0002] Formwork support components in building construction are structural parts used to support and fix concrete formwork. They are mainly used to maintain the shape and position of the formwork during concrete pouring, ensuring that the concrete can solidify according to the expected design shape. Support frames are mainly used to support the vertical and horizontal forces of the formwork, and common types include steel pipe supports and aluminum alloy supports.

[0003] Formwork support frames are used to fix formwork and prevent it from deforming or moving during concrete pouring, ensuring that the shape and size of the concrete structure meet the requirements. For the bottom formwork of some concrete structures, formwork support frames are also an important tool for transferring the weight of the uncured concrete at the top of the formwork to the ground.

[0004] In the prior art, patent document CN221920286U discloses a formwork support frame support device for construction. This device involves placing the support column vertically, then removing multiple legs from multiple first slots and placing them on the ground. The end of the second top rod contacts and presses against the top of the third slot. This allows the formwork support frame to remain stable when supporting the formwork on uneven ground, preventing tilting due to stress. It also effectively transmits pressure from the formwork to the ground, reducing formwork deformation. However, in actual construction, when supporting floor formwork, a full-span support frame is typically installed below the floor to be poured. Multiple support devices are then inserted into the upper ends of the vertical pipes of the full-span support frame to support the floor formwork. This support device is not suitable for use in conjunction with a full-span support frame.

[0005] The existing support system consists of screws, top plates, and screw sleeves, and has a simple structure. After the full-span support frame is arranged, multiple support devices are installed sequentially on the upper end of the vertical pipe. Installing the support devices requires manual climbing and carrying multiple devices, posing significant safety hazards during the installation process. Utility Model Content

[0006] The main objective of this invention is to provide a support device that can be pre-installed on the vertical pipes before laying the full-span support frame. Pre-installing the support device on the upper end of the vertical pipes of the full-span support frame eliminates the need for workers to climb to heights to install the support device, improving installation efficiency and reducing safety hazards during construction.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: A formwork support device for construction engineering includes a screw rod, a support plate fixed to the upper end of the screw rod, a screw sleeve threaded onto the screw rod, a sliding sleeve concentrically fitted onto the screw rod below the screw sleeve, the screw rod being able to slide within the sliding sleeve, a fixed sleeve concentrically arranged on the outer side of the sliding sleeve, the upper end of the fixed sleeve being bent towards its center to form a bent portion, the bent portion being fixed to the outer side of the sliding sleeve, a cavity being formed between the fixed sleeve portion below the bent portion and the sliding sleeve, multiple long grooves evenly distributed around the circumference of the fixed sleeve portion below the bent portion, the length direction of the long grooves being parallel to the axial direction of the fixed sleeve, a rotating rod elastically rotatably connected within the long groove, the lower end of the rotating rod being inclined away from the axis of the fixed sleeve, the upper end of the rotating rod contacting the outer edge of the sliding sleeve, and a rubber block being fixed to the side of the lower end of the rotating rod facing the sliding sleeve.

[0008] Specifically, a support sleeve is concentrically fixed at the lower end of the threaded sleeve, and the sliding sleeve is located inside the support sleeve. The lower end of the support sleeve is in rotatable contact with the upper end of the bent part of the fixed sleeve.

[0009] Specifically, a baffle is concentrically fixed at the lower end of the screw, and the baffle is used to limit the movement of the sliding sleeve.

[0010] Specifically, the two ends of the support plate are bent upwards at 90 degrees to form vertical parts, and the two vertical parts are arranged opposite each other.

[0011] Specifically, a rotating shaft is fixed on the rotating rod, and the rotating shaft is rotatably connected to the fixed sleeve. A torsion spring is sleeved on the rotating shaft, with one end of the torsion spring fixedly connected to the rotating shaft and the other end of the torsion spring fixedly connected to the fixed sleeve.

[0012] Specifically, the rubber block is made of elastic rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This support device achieves rapid installation through a plug-in design. When the sliding sleeve is inserted into the upper end of the vertical pipe, the rotating rod automatically rotates outward under the contact of the vertical pipe. At the same time, the rubber block is compressed and deformed and presses tightly against the outer edge of the vertical pipe, forming a frictional self-locking mechanism. This eliminates the need for additional fastening tools, simplifies the operation process, and ensures stability during construction vibrations. It reduces manual intervention and improves construction efficiency, making it especially suitable for high-altitude or complex environments.

[0014] 2. The threaded sleeve design allows users to manually rotate the sleeve to drive the screw and support plate to move up and down, achieving stepless adjustment of the support height. The rotational contact between the lower end of the sleeve and the upper end of the sliding sleeve allows for smooth movement, facilitating precise matching of the template height, significantly improving construction flexibility, avoiding the cumbersome component replacement required by traditional support devices, saving time and adapting to dynamic construction conditions.

[0015] 3. The support sleeve is concentrically fixed to the lower end of the threaded sleeve and rotates in contact with the bent part of the fixed sleeve, which disperses the load pressure, enhances the support strength of the threaded sleeve, improves the compressive strength and durability of the overall device, reduces the risk of deformation or failure, ensures uniform and reliable support of the template, and is suitable for heavy-duty working conditions.

[0016] 4. The elastic rotation of the rotating rod and the deformation design of the rubber block play a buffering role during installation and support, effectively absorbing unexpected impacts or vibrations during construction. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1: Refer to Figures 1-5 As shown, a formwork support device for construction engineering includes a screw rod 1, with a support plate 4 fixed to the upper end of the screw rod 1. The two ends of the support plate 4 are bent upward at 90 degrees to form vertical parts. The two vertical parts are arranged opposite to each other. When the support plate 4 supports square timber, the square timber is located between the two vertical parts.

[0028] A threaded sleeve 5 is threaded onto the screw 1. A sliding sleeve 2 is concentrically fitted onto the screw 1 below the threaded sleeve 5. The screw 1 can slide within the sliding sleeve 2. A baffle 3 is concentrically fixed at the lower end of the screw 1. The baffle 3 is used to limit the sliding sleeve 2.

[0029] A fixed sleeve 7 is concentrically provided on the outer side of the sliding sleeve 2. The upper end of the fixed sleeve 7 is bent towards its center to form a bent part. The bent part is fixed on the outer side of the sliding sleeve 2. A cavity is formed between the fixed sleeve 7 below the bent part and the sliding sleeve 2.

[0030] The fixed sleeve 7 below the bend has multiple elongated grooves 8 evenly distributed around its circumference. The length direction of the elongated grooves 8 is parallel to the axial direction of the fixed sleeve 7. A rotating rod 9 is elastically rotatably connected within the elongated groove 8. Specifically, a rotating shaft 11 is fixed on the rotating rod 9. The rotating shaft 11 is rotatably connected to the fixed sleeve 7. A torsion spring is sleeved on the rotating shaft 11. One end of the torsion spring is fixedly connected to the rotating shaft 11, and the other end of the torsion spring is fixedly connected to the fixed sleeve 7.

[0031] The lower end of the rotating rod 9 is inclined away from the axis of the fixed sleeve 7, the upper end of the rotating rod 9 is in contact with the outer edge of the sliding sleeve 2, and a rubber block 10 is fixed to the side of the lower end of the rotating rod 9 facing the sliding sleeve 2. The rubber block 10 is made of elastic rubber.

[0032] When laying the full-span support frame, pre-install this support device onto the vertical pipe 12 of the full-span support frame. (Refer to...) Figures 6-8 As shown, the sliding sleeve 2 is inserted into the upper end of the vertical tube 12, so that the upper end of the vertical tube 12 is inserted into the insertion cavity. During the insertion of the upper end of the vertical tube 12 into the insertion cavity, when the vertical tube 12 contacts the upper end of the rotating rod 9, the upper end of the rotating rod 9 rotates outward towards the fixed sleeve 7, and the lower end of the rotating rod 9 rotates towards the axis of the fixed sleeve 7. At the same time, the rubber block 10 is compressed and deformed, pressing tightly against the outer edge of the vertical tube 12. When the upper end of the vertical tube 12 contacts the bent part of the fixed sleeve 7, the support device is installed in place. At this time, under the action of the friction between the rubber block 10 and the outer edge of the vertical tube 12, the support device is stably installed on the upper end of the vertical tube 12.

[0033] After the full-span support frame is laid, hold the support plate 4 and rotate the screw sleeve 5. Since the lower end of the screw sleeve 5 is in rotational contact with the upper end of the sliding sleeve 2, the screw rod 1 and the support plate 4 can move up and down during the rotation of the screw sleeve 5, so that the support plate 4 can be used to support the template.

[0034] Example 2: Based on Example 1, referring to... Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, a support sleeve 6 is concentrically fixed at the lower end of the threaded sleeve 5, and the sliding sleeve 2 is located inside the support sleeve 6. The lower end of the support sleeve 6 is in rotatable contact with the upper end of the bent part of the fixed sleeve 7.

[0035] In this embodiment, by providing a support sleeve 6, the fixing sleeve 7 can support the threaded sleeve 5 through the support sleeve 6, thereby improving the support effect on the threaded sleeve 5.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
