Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a drop plate template reinforcement device. Background Art

[0002] Drop-down formwork usually refers to a formwork system used to create height differences in floor or roof panels during construction. In buildings, the thickness of floor decoration varies from room to room depending on its function and the materials used. For example, bathrooms, kitchens and other places have higher requirements for waterproofing and require thicker materials, so the floors of these rooms are often lower than other rooms, which is the so-called "drop-down". This height difference in the structure is designed to ensure that the ground is basically flat after the completion of various materials, to avoid obstacles and facilitate use. Drop-down formwork is an important tool for achieving this structural height difference. During the construction process, the formwork needs to be prepared according to the design size to ensure that the structure at the drop-down position meets the specification requirements, and the drop-down formwork is reinforced by reinforcement devices.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the drop-down formwork reinforcement device in the prior art cannot be adjusted according to the size of different drop-down formworks, has a small scope of use, and increases construction costs. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a drop-plate formwork reinforcement device.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a reinforcement device for a drop plate formwork, comprising four reinforcement rods, each reinforcement rod side wall is provided with a slide groove, each of the slide grooves is slidably connected with a sliding rod, each of the sliding rod side walls is fixed to the adjacent reinforcement rod side walls, each of the sliding rod side walls is provided with a tooth groove, each of the slide groove inner walls is provided with a receiving groove, a fixing assembly for fixing the sliding rod is installed on the reinforcement rod, and the fixing assembly includes a fixing rod that is penetrated and slidably connected to the reinforcement rod, a limit block fixed to the end of the fixing rod and meshed with the tooth groove, and a control block fixed to the end of the fixing rod away from the limit block.

[0006] By adopting the above technical scheme, when the drop-down formwork needs to be reinforced, the staff moves multiple sliding rods to make the side walls of the four reinforcement rods press against the drop-down formwork, and then moves the fixed rod and the limit block through the control block to make the limit block engage with the tooth groove, thereby fixing the position of the sliding rod, thereby reinforcing the drop-down formwork. This is conducive to adjusting the reinforcement device according to the size of different drop-down formworks, increasing the scope of use and reducing construction costs.

[0007] Furthermore, a mounting groove is provided on the side wall of each reinforcement rod close to the control block, and a spring is provided in each mounting groove, one end of the spring is fixed to the inner wall of the mounting groove, and the other end of the spring is fixed to the side wall of the control block.

[0008] By adopting the above technical solution, the control block keeps the fixed block in meshing with the tooth groove under the elastic force of the spring, thereby reducing the probability of the limit block being separated from the tooth groove and causing the sliding rod to move.

[0009] Furthermore, a rubber sheet is fixed to the side wall of the limiting block away from the fixing rod.

[0010] By adopting the above technical solution, the rubber sheet is made of rubber material, and its surface has a large friction coefficient. The limit block cooperates with the tooth groove and presses against the rubber sheet, which increases the friction between the limit block and the tooth groove and enhances the fixing effect on the sliding rod.

[0011] Furthermore, the cross section of the fixing rod is rectangular.

[0012] By adopting the above technical solution, the rectangular cross section is more stable than the circular cross section, and the situation in which the limit block is separated from the tooth groove due to the rotation of the fixing rod is avoided.

[0013] Furthermore, a rotation groove is provided on the side wall of the control block close to the reinforcing rod, a fixing groove is provided on the inner wall of the rotation groove, a rotating shaft is rotatably connected to the inner wall of the fixing groove, and a support block is fixedly sleeved on the rotating shaft.

[0014] By adopting the above technical solution, when the position of the sliding rod needs to be adjusted, the staff moves the control block to the side away from the tooth groove, and rotates the support block to open it, so that the side wall of the support block is pressed against the side wall of the reinforcement rod, thereby limiting the position of the control block, eliminating the tedious operation of pulling the control block with one hand and moving the sliding rod with the other hand, making it easier for the staff to pull the sliding rod to move in the slide groove.

[0015] Furthermore, a torsion spring is arranged in the fixing groove, one end of the torsion spring is fixed to the inner wall of the fixing groove, and the other end of the torsion spring is fixed to the side wall of the support block.

[0016] By adopting the above technical solution and the setting of the torsion spring, the support block automatically opens under the torque of the torsion spring after the staff pulls the control block, eliminating the tedious operation of the staff manually turning the support block and facilitating the staff to limit the control block.

[0017] Furthermore, the cross-sections of the slide groove and the slide rod are both dovetail-shaped.

[0018] By adopting the above technical solution, the dovetail-shaped sliding rod and the sliding groove keep the sliding rod and the side wall of one side of the reinforcement rod flush with each other, thereby preventing the sliding rod from falling off from the notch on one side of the sliding groove away from the control block.

[0019] Furthermore, a limiting groove is provided on the inner wall of the slide groove, and a sliding block which is slidably connected to the limiting groove is fixed on the side wall of the sliding rod.

[0020] By adopting the above technical solution, the slider is slidably connected to the limit groove, which limits the movement range of the sliding rod and avoids the situation where the sliding rod moves too much and falls out of the sliding groove.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, when the drop-down template needs to be reinforced, the staff moves multiple sliding rods to make the side walls of the four reinforcement rods close to the drop-down template, and then moves the fixed rod and the limit block through the control block to make the limit block engage with the tooth groove, thereby fixing the position of the sliding rod, thereby reinforcing the drop-down template, which is conducive to adjusting the reinforcement device according to the size of different drop-down templates, expanding the scope of use and reducing construction costs;

[0023] 2. In the present application, the control block keeps the fixed block in meshing with the tooth groove under the elastic force of the spring, thereby reducing the probability of the limit block being separated from the tooth groove and causing the sliding rod to move;

[0024] 3. In the present application, when the position of the sliding rod needs to be adjusted, the staff moves the control block to the side away from the tooth groove, and rotates the support block to open it so that the side wall of the support block is pressed against the side wall of the reinforcement rod, thereby limiting the position of the control block, eliminating the tedious operation of pulling the control block with one hand and moving the sliding rod with the other hand, making it easier for the staff to pull the sliding rod to move in the slide groove.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0032] like Figure 1-5 As shown, an embodiment of the present application discloses a drop plate formwork reinforcement device, including a reinforcement rod 1, a sliding rod 2 and a fixing assembly 3.

[0033] The reinforcement rod 1 is a horizontally arranged rectangular rod-shaped structure, and there are four reinforcement rods 1. Each reinforcement rod 1 has a side wall with a slide groove 11, and the cross section of the slide groove 11 is dovetail-shaped. Each slide groove 11 has an inner wall with a receiving groove 12. The sliding rod 2 is a dovetail-shaped structure, and there are four sliding rods 2. The four sliding rods 2 are respectively connected to the four slide grooves 11 by sliding. The side wall of each sliding rod 2 is fixed to the adjacent side wall of the reinforcement rod 1, and each side wall of the sliding rod 2 has a tooth groove 21.

[0034] The fixing assembly 3 is installed on the reinforcement rod 1 and is used to fix the sliding rod 2. The fixing assembly 3 includes a fixing rod 31, a limit block 32 and a control block 33. The fixing rod 31 is a horizontally arranged rod-shaped structure, and the fixing rod 31 is penetrated and slidably connected to the reinforcement rod 1. The limit block 32 is fixed to the end of the fixing rod 31, and the limit block 32 is engaged with the tooth groove 21. The control block 33 is a rectangular parallelepiped structure, and the control block 33 is fixed to the end of the fixing rod 31 away from the limit block 32.

[0035] When the drop-down formwork needs to be reinforced, the staff moves multiple sliding rods 2 to make the side walls of the four reinforcement rods 1 press against the drop-down formwork, and then moves the fixed rod 31 and the limit block 32 through the control block 33 to make the limit block 32 engage with the tooth groove 21, thereby fixing the position of the sliding rod 2, so as to reinforce the drop-down formwork. This is conducive to adjusting the reinforcement device according to the size of different drop-down formworks, increasing the scope of use and reducing construction costs. The dovetail-shaped sliding rod 2 and the slide groove 11 keep the sliding rod 2 flush with the side wall of the reinforcement rod 1 on one side, avoiding the sliding rod 2 from falling off from the notch on the side of the slide groove 11 away from the control block 33.

[0036] In order to reduce the probability of the limit block 32 being separated from the tooth groove 21, a mounting groove 13 is opened on the side wall of each reinforcement rod 1 close to the control block 33, and a spring 4 is arranged in each mounting groove 13, one end of the spring 4 is fixed to the inner wall of the mounting groove 13, and the other end of the spring 4 is fixed to the side wall of the control block 33. Under the action of the elastic force of the spring 4, the control block 33 keeps the fixed block in a state of meshing with the tooth groove 21, thereby reducing the probability of the limit block 32 being separated from the tooth groove 21 and causing the sliding rod 2 to move.

[0037] In order to enhance the fixing effect on the sliding rod 2, a rubber sheet 5 is fixed to the side wall of the limit block 32 away from the fixing rod 31. The rubber sheet 5 is made of rubber material and its surface has a large friction coefficient. The limit block 32 cooperates with the tooth groove 21 and presses against the rubber sheet 5, thereby increasing the friction between the limit block 32 and the tooth groove 21, thereby enhancing the fixing effect on the sliding rod 2.

[0038] In order to prevent the fixing rod 31 from rotating, the fixing rod 31 has a rectangular cross section, which is more stable than a circular cross section, thereby preventing the limit block 32 from being separated from the tooth groove 21 due to the rotation of the fixing rod 31.

[0039] In order to facilitate pulling the sliding rod 2, a rotating groove 331 is opened on the side wall of the control block 33 close to the reinforcement rod 1, and a fixed groove 332 is opened on the inner wall of the rotating groove 331. The inner wall of the fixed groove 332 is rotatably connected to the rotating shaft 6, and a support block 7 is fixedly sleeved on the rotating shaft 6. When it is necessary to adjust the position of the sliding rod 2, the staff moves the control block 33 to the side away from the tooth groove 21, and rotates and opens the support block 7 so that the side wall of the support block 7 is tightly pressed against the side wall of the reinforcement rod 1, thereby limiting the position of the control block 33, eliminating the tedious operation of pulling the control block 33 with one hand and moving the sliding rod 2 with the other hand, and facilitating the staff to pull the sliding rod 2 to move in the sliding groove 11.

[0040] In order to facilitate the limiting of the control block 33, a torsion spring 8 is arranged in the fixing groove 332, one end of the torsion spring 8 is fixed to the inner wall of the fixing groove 332, and the other end of the torsion spring 8 is fixed to the side wall of the support block 7. The setting of the torsion spring 8 enables the support block 7 to automatically open under the torque of the torsion spring 8 after the staff pulls the control block 33, eliminating the tedious operation of the staff to manually rotate the support block 7, thereby facilitating the staff to limit the control block 33.

[0041] In order to prevent the sliding rod 2 from moving too much, a limiting groove 14 is opened on the inner wall of the slide groove 11, and a slider 9 is fixed to the side wall of the sliding rod 2 which is slidably connected to the limiting groove 14. The slider 9 is slidably connected to the limiting groove 14, which limits the movement range of the sliding rod 2, thereby preventing the sliding rod 2 from moving too much and detaching from the slide groove 11.

[0042] The use principle of a drop-plate formwork reinforcement device in the present embodiment is as follows: when the drop-plate formwork needs to be reinforced, the staff moves multiple sliding rods 2 to make the side walls of the four reinforcement rods 1 press against the drop-plate formwork, and then moves the fixed rod 31 and the limit block 32 through the control block 33 to make the limit block 32 engage with the tooth groove 21, thereby fixing the position of the sliding rod 2, so as to reinforce the drop-plate formwork, which is conducive to adjusting the reinforcement device according to the size of different drop-plate formworks, expanding the scope of use and reducing construction costs. The dovetail-shaped sliding rod 2 and the slide groove 11 keep the sliding rod 2 flush with the side wall of the reinforcement rod 1 on one side, avoiding the sliding rod 2 from falling off from the notch on the side of the slide groove 11 away from the control block 33.

[0043] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
