Description

Technical Field

[0001] This utility model belongs to the field of template installation, specifically a template installation and correction device. Background Technology

[0002] Formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components into specified positions and geometric dimensions, maintain their correct position, and bear the self-weight of the formwork and external loads acting on it. The purpose of formwork engineering is to ensure the quality and safety of concrete engineering, accelerate construction progress, and reduce project costs. Formwork installation must meet elevation requirements to ensure that the poured concrete structure conforms to design requirements. Therefore, adjusting the formwork elevation is an essential step in formwork installation. Currently, formwork height adjustment is usually done using tools such as crowbars or jacks. After lifting the formwork from the bottom to the required elevation using crowbars or jacks, support blocks are used at the bottom of the formwork for support.

[0003] Utility model patent application CN202020294558.6 discloses a template height adjustment device, which includes a fixed plate, a nut fixed to the back of the fixed plate, and an adjusting bolt threaded into the nut. In use, the fixed plate is connected to the bottom of the template, and the bottom end of the adjusting bolt rests against a support surface. Rotating the adjusting bolt pushes the fixed plate to move axially along the adjusting bolt to achieve height adjustment. However, this structure has the following drawbacks:

[0004] Firstly, the bottom of the adjusting bolt rests against the support surface, and the weight of the template is transferred to the adjusting bolt through the fixing plate. Furthermore, the bottom of the adjusting bolt rotates on the support surface to complete the height adjustment, which increases the probability of damaging the support surface.

[0005] Secondly, it can only perform vertical correction and cannot adjust horizontally, which means that horizontal adjustment needs to be done separately, affecting adjustment efficiency. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] In this utility model, the terms "vertical," "horizontal," "upper," "lower," "top," and "bottom," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientation or positional relationship shown is for the purpose of describing the present invention only, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0026] Template installation and correction device, such as Figure 1 As shown, it includes a base support plate 1, a vertical screw 6, a horizontal screw 10, a support frame 5, and a bracket for supporting the template;

[0027] A nut 7 is threaded onto the vertical screw 6, and the bracket is fixedly connected to the nut 7. A horizontally extending travel track 2 is laid on the top surface of the base bearing plate 1, and the support frame 5 is movably installed on the travel track 2. The vertical screw 6 is connected to the support frame 5 through a rolling bearing, and a power system is provided to drive the vertical screw 6 to rotate. That is, the support frame 5 provides support for the vertical screw 6, so that the vertical screw 6 can rotate around its axis. During the rotation of the vertical screw 6, the nut 7 is pushed to move along the axis of the vertical screw 6, thereby driving the bracket fixed on the nut 7 to move vertically. Since the template is supported on the bracket, the template can move up and down, thus achieving the purpose of vertically adjusting the installation elevation of the template.

[0028] In this manual, the horizontal direction refers to the extension direction of the walking track 2, which is also the length direction of the walking track 2; the vertical direction refers to the direction that is perpendicular to both the horizontal and vertical directions, which is also the width direction of the walking track 2.

[0029] Fixed plates 3 are respectively provided at both ends of the top surface of the base bearing plate 1 along the transverse direction. The support frame 5 is located between the two fixed plates 3. The horizontal screw 10 passes through the support frame 5 and its two ends are rotatably installed on the corresponding fixed plates 3 through rolling bearings. Nuts are provided on the horizontal screw 10, and the nuts are fixedly connected to the support frame 5. The rotation of the horizontal screw 10 drives the support frame 5 to move along the travel track 2. The support frame 5 is installed on the travel track 2, and the two are limited by a limiting structure, so that the support frame 5 can only move linearly along the extension direction of the travel track 2 and cannot rotate. When the support frame 5 is connected to the nuts on the horizontal screw 10, the horizontal screw 10 rotates, and the nuts move axially along the horizontal screw 10 without rotating, thereby driving the support frame 5 to move horizontally within the range of the base bearing plate 1, and then driving the bracket, so that the template sitting on the bracket can be adjusted horizontally.

[0030] The template installation and correction device uses vertical screws 6 and horizontal screws 10 to achieve synchronous adjustment of the elevation above the horizontal position, thus solving the problem of compound deviations in template construction.

[0031] In use, the base support plate 1 is supported on the ground. Compared with the vertical screw 6 being supported on the ground, it has a larger support area. Moreover, the vertical screw 6 does not exert any force on the ground when it rotates, thus protecting the concrete layer from damage. In addition, the bottom end of the vertical screw 6 is connected to the support frame 5 through a rolling bearing, which reduces the resistance that hinders the rotation of the vertical screw 6 and makes it easier to drive the vertical screw 6 to rotate.

[0032] Among them, such as Figure 3As shown, the power system includes a drive motor 11, a drive gear 12, and a driven gear 13. The output shaft of the drive motor 11 is coaxially connected to the drive gear 12, and the driven gear 13 is coaxially mounted on the vertical screw 6. The drive gear 12 meshes with the driven gear 13. The system achieves height adjustment by electrically driving the vertical screw 6 using a motor, and combines the bidirectional adjustment of the vertical screw 6 and the horizontal screw 10 with the integrated load-bearing design formed by the base bearing plate 1, the support frame 5, and the transmission system. This overcomes the core problems of low efficiency and insufficient precision in adjusting complex deviations during the construction of tall formwork.

[0033] Construction sites often experience dust and debris. To prevent these elements from affecting the power system, this invention uses a box-shaped support frame 5. The drive motor 11, drive gear 12, and driven gear 13 are all located within the support frame 5. The support frame 5 encloses the power system, isolating it from dust and debris and protecting the system.

[0034] To further improve regulation efficiency, preferably, such as Figure 2 As shown, a drive handle 15 is provided at one end of the horizontal screw 10; two foot switches 4 are provided at the bottom of the support frame 5 on one side of the walking track 2, one being a forward foot switch and the other a reverse foot switch; the forward foot switch is connected to the drive motor 11, turning the drive motor 11 forward; the reverse foot switch is connected to the drive motor 11, turning the drive motor 11 in reverse; vertically, the elevation between the drive handle 15 and the foot switch 4 is 80-90cm. This arrangement allows the operator to manually control the drive handle 15 while simultaneously controlling the drive motor 11 by stepping on the foot switch 4, thus enabling simultaneous horizontal and vertical adjustments without requiring sequential adjustments, further improving adjustment efficiency. In practical use, stepping on the forward foot switch starts the drive motor 11 to rotate forward, causing the support frame of the template to move upward; stepping on the reverse foot switch starts the drive motor 11 to rotate in reverse, causing the support frame of the template to move downward.

[0035] To adapt to the lack of power supply at construction sites, preferably, a battery 14 for powering the drive motor 11 is installed inside the support frame 5.

[0036] Preferred, such as Figure 4 As shown, the bracket includes a bracket plate 9 and a connecting plate 8; the connecting plate 8 is vertically arranged, and its bottom end is connected to the horizontally arranged bracket plate 9. The bracket plate 9 and the connecting plate 8 form an L-shaped frame. The bracket plate 9 provides support at the bottom of the template, lifting the template. The connecting plate 8 connects the bracket plate 9 to the vertical screw 6, and also supports the template from the side.

[0037] To ensure smooth lifting, the bottom section of the vertical screw 6 is located inside the support frame 5, and the top section is located outside the support frame 5; a nut 7 is provided on the bottom section and the top section of the vertical screw 6 respectively; a connecting block 17 is provided on the bottom back of the connecting plate 8, and the connecting block 17 passes through the vertical strip hole on the support frame 5 and is connected to the nut 7.

[0038] To ensure smooth horizontal movement, two parallel tracks 2 are laid out. The bottom of the support frame 5 is equipped with four small wheels 16, which cooperate with the track 2 to longitudinally constrain the support frame 5 to the track 2.

[0039] The base support plate 1 is made of 400mm×300mm×3mm thick steel plate to increase the contact area with the ground and improve stability. A 10×10mm running track 2 is welded to each of the two sides of the base support plate along the length direction, i.e., the 400mm side, to support the small wheels 16 of the frame.

[0040] The bracket plate 9 is made of 100mm×50×3mm steel plate and is connected to the connecting plate 8 by welding. Nuts that match the two vertical spiral rods are welded to the connecting plate 8 through the connecting block 17 to form a vertically liftable "L" shaped template support bracket.

[0041] The support frame is made of 30×30×2mm angle iron welded into a 300×300×400mm high skeleton, and the surrounding area is sealed with 2mm sheet iron. Vertical strip holes are opened on the sheet iron within the vertical movement range of the base bearing system.

[0042] The vertical screw 6 and the horizontal screw rod are fully threaded screw rods with a diameter of 12mm and a pitch of 3.0mm. The gear and nut are matched with the screw rod and are welded to the bearing connection.

[0043] The drive motor and battery are 20V 20Ah geared motors with a torque of not less than 90N·m.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
