Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a temporary floor slab reinforcement device with pre-axial force. Background Technology

[0002] During the construction of building structures, structural floor slabs may require temporary heavy vehicle or heavy load transport. Faced with unforeseen reinforcement needs, a post-construction reinforcement strategy is often adopted. This involves using several support pipes under the floor slab to temporarily reinforce it. While this post-construction reinforcement strategy can respond quickly and solve sudden problems of insufficient floor slab load-bearing capacity, the support pipes are often only placed under the floor slab. The support pipes do not generate sufficient pre-axial force to support the floor slab. As a result, when the floor slab is temporarily reinforced, the support pipes do not actually play their due supporting role. In most cases, when the floor slab is under load, the main load is still borne by the original structure, which greatly reduces the reinforcement effect and fails to fully achieve the expected reinforcement goals. The installation and stability of the building structure under extreme load conditions cannot be guaranteed. Utility Model Content

[0003] To address the deficiencies in existing technologies, this application provides a temporary floor slab reinforcement device with pre-axial force, thereby solving the technical problem that the support pipe in the existing temporary floor slab reinforcement device does not generate sufficient pre-axial force to support the floor slab, resulting in unsatisfactory temporary floor slab reinforcement effect.

[0004] To achieve the objectives of the above application, the technical solution provided in this application is as follows:

[0005] A temporary floor slab reinforcement device with pre-axial force is characterized by comprising a base, an open sleeve fixedly disposed on the upper surface of the base, a cylindrical support seat disposed inside the sleeve, the lower end of the support seat being connected to the base, a sliding cylinder for placing a support tube slidably disposed inside the sleeve, the support tube being slidably connected to the sleeve, a vertical groove disposed on the sleeve, a connecting plate disposed inside the groove, one end of the connecting plate being fixedly connected to the sliding cylinder, the other end of the connecting plate extending out of the groove, a lifting device driving the connecting plate to move up and down along the groove so that the upper end of the support tube abuts against the lower surface of the floor slab, when the connecting plate is not lifted, the sliding cylinder is placed on the support seat, a horizontal locking groove disposed on the upper side of the support seat, when the sliding cylinder leaves the support seat, the small end of a wedge-shaped locking piece can be inserted into the gap between the sliding cylinder and the support seat through the locking groove to maintain the displacement of the sliding cylinder and the pre-axial force of the support tube.

[0006] In one embodiment, the sleeve and the support are concentrically arranged, and the inner diameter of the sleeve is equal to the outer diameter of the support.

[0007] In one embodiment, the sleeve is provided with two sliding grooves that are symmetrical about the central axis of the sleeve, and the slide is provided with two connecting plates that are symmetrical about the central axis of the slide.

[0008] In one embodiment, the sleeve is provided with two grooves that are symmetrical about the central axis of the sleeve, and the line connecting the two grooves is perpendicular to the line connecting the two sliding grooves.

[0009] In one embodiment, the lifting device is a jack that can display the lifting force, the jack is disposed below the connecting plate, and the lifting end of the jack contacts the end of the connecting plate that extends out of the slide groove.

[0010] In one implementation, the jack stops lifting the connecting plate when the jacking force reaches a set value.

[0011] In one embodiment, the base, support, sleeve, connecting plate, and wedge-shaped locking plate are all made of high-strength materials.

[0012] In one embodiment, the support pipe is a steel pipe, and the support base is a steel pier.

[0013] Compared with the prior art, this application has at least the following beneficial effects:

[0014] The temporary floor slab reinforcement device with pre-axial force described in this application uses a jacking device to firmly press the support pipe of the temporarily reinforced floor slab against the floor slab. By using wedge-shaped locking plates to engage in the gap between the sliding cylinder and the support seat, the relative position between the support pipe and the support seat can be effectively locked, ensuring that the pre-axial force within the steel pipe is stably maintained after the jack is unloaded and will not be lost due to external forces. The operation is simple, efficient, and safe. Construction personnel only need to complete temporary fixing at one support pipe before quickly moving to the next steel pipe to repeat the operation, greatly improving the efficiency and quality of the reinforcement work. Furthermore, the temporary reinforcement device described in this application can be repeatedly reused in subsequent projects, significantly improving economic and cost-effectiveness.

[0025] To better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings.

[0026] This embodiment provides a temporary floor slab reinforcement device with pre-axial force, such as... Figure 1-4As shown, the device includes a base 2, with an open sleeve 3 fixedly mounted on the upper surface of the base 2. A cylindrical support 201 is installed inside the sleeve 3, with its lower end connected to the base 2. A sliding cylinder 5 for placing a support tube 1 is slidably mounted inside the sleeve 3, and the support tube 1 is slidably connected to the sleeve 3. A vertical groove 4 is provided on the sleeve 3, and a connecting plate 6 is installed inside the groove 4. One end of the connecting plate 6 is fixedly connected to the sliding cylinder 5, and the other end of the connecting plate 6 extends out of the groove 4. A lifting device is also included. 7 can drive the connecting plate 6 to move up and down along the slide groove 4 so that the upper end of the support pipe 1 abuts against the lower surface of the floor slab 10. When the connecting plate 6 is not lifted, the slide cylinder 5 is placed on the support base 201. The sleeve 3 is provided with a transverse groove 9. The groove 9 is located on the upper side of the support base 201. When the slide cylinder 5 leaves the support base 201, the small end of the wedge-shaped locking piece 8 can be inserted into the gap between the slide cylinder 5 and the support base 201 through the groove 9 to maintain the displacement of the slide cylinder 5 and the pre-axial force of the support pipe 1.

[0027] In this embodiment, the sleeve 3 and the support base 201 are concentrically arranged, and the inner diameter of the sleeve 3 is equal to the outer diameter of the support base 201. Two grooves 4 symmetrical about the central axis of the sleeve 3 are provided on the sleeve 3, and two connecting plates 6 symmetrical about the central axis of the sliding cylinder 5 are provided on the sliding cylinder 5. This allows for the stable lifting of the support pipe 1 by steadily raising the sliding cylinder 5, ensuring that the pre-axial force is efficiently and stably transmitted to the interior of the support pipe 1. Two slots 9 symmetrical about the central axis of the sleeve 3 are provided on the sleeve 3, and the line connecting the two slots 9 is perpendicular to the line connecting the two grooves 4, so that the wedge-shaped locking piece 8 can be inserted into the slot 9.

[0028] In this embodiment, the lifting device 7 is a jack that can display the lifting force. The jack is located below the connecting plate 6, and the lifting end of the jack contacts the end of the connecting plate 6 that extends out of the slide groove 4. When the lifting force of the jack reaches the set value, the jack stops lifting the connecting plate. The lifting force of the jack is proportional to the pre-axial force of the support pipe 1. When the lifting force of the jack reaches the set value, sufficient pre-axial force is formed inside the support pipe 1 to support the floor slab. To avoid the jacking force being too large and damaging the support pipe, the jack stops working when the lifting force reaches the set value.

[0029] To ensure the load-bearing capacity of the temporary floor reinforcement device, the base 2, support 201, sleeve 3, and connecting plate 6 are all made of high-strength materials. In this embodiment, the base 2, support 201, sleeve 3, and connecting plate 6 are all made of Q345 steel. The wedge-shaped locking plate 8 in this embodiment is also made of high-strength material. The support pipe 1 is a steel pipe, and the support 201 is a steel pier.

[0030] The working principle of the temporary floor slab reinforcement device in this embodiment is as follows:

[0031] like Figure 5As shown, the support pipe 1 is placed vertically on the slide cylinder 5 inside the sleeve 3, with the upper end of the support pipe 1 already in contact with the lower surface of the floor slab 10. The connecting plate 6 is driven to move up and down along the slide groove 4 by the lifting device 7, so that the upper end of the support pipe 1 abuts against the lower surface of the floor slab 10. When the lifting force of the lifting device 7 reaches the design value, the lifting drive plate 6 is stopped. The small end of the wedge-shaped locking piece 8 is inserted into the gap between the slide cylinder 5 and the support seat 201 through the slot 9 to maintain the displacement of the slide cylinder 5 and the pre-axial force of the support pipe 1. The lifting device is gradually removed so that the wedge-shaped locking piece 8 can ensure the stability of the support pipe 1. The lifting device 7 is then used in other temporary reinforcement devices for the floor slab.

[0032] After the lifting device 7 applies force, the wedge-shaped locking plates 8 are hammered into the gap between the support pipe 1 and the support base 201 by the construction personnel through the slot 9 of the sleeve 3. As the wedge-shaped locking plates 8 are gradually pushed in and hammered to the center of the steel pipe, they will effectively lock the relative position between the steel pipe and the base, thereby ensuring that the pre-axial force in the support base 201 is stably maintained after the lifting device 7 is unloaded and will not be lost due to external forces.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation methods of the application or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of this application, and all of them should be covered within the scope of the technical solutions claimed in this application.
