Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an auxiliary device and method for supporting inclined bottom formwork. Background Technology

[0002] In the development of modern architectural engineering, villas, theaters, art galleries, and other civil buildings often adopt sloping roofs to meet drainage, energy-saving, and architectural aesthetic requirements. Some buildings also feature sloping floor slabs such as loft mezzanines or viewing platforms with sloping cantilever slabs. The bottom surfaces of beams and slabs in this type of structure are all sloping. If a conventional horizontal formwork support system is used directly, lateral slippage during concrete pouring can easily lead to structural deviations, and may even cause the beam and slab formwork support system to slip horizontally or overturn due to eccentric compression.

[0003] Currently, a utility model patent for "Support Device for Tunnels Upper Armpit Corner Template" has been found on domestic patent websites. This "support device" includes a first fixing structure and a second fixing structure. Both the first fixing structure and the second fixing structure are right-angled triangular structures. The first fixing structure and the second fixing structure are arranged in parallel and are fixedly connected by a connecting structure, so that the hypotenuses of the first fixing structure and the second fixing structure are located on the same plane, forming a supporting inclined surface. An armpit corner template support member is vertically arranged on the supporting inclined surface, with one end of the armpit corner template support member set on the hypotenuse of the first fixing structure and the other end set on the hypotenuse of the second fixing structure. The aspect most similar to the present application's solution lies in the method of force transmission path on the inclined bottom surface of the structural beam and slab. The existing solution involves installing a support device for the upper armpit corner formwork of a tunnel within the armpit corner range on the inclined bottom surface of the beam and slab to achieve the formwork support erection under the inclined bottom surface of the structural beam and slab. The present application's solution involves embedding and installing an inclined bottom surface formwork support top support auxiliary device under the inclined bottom surface of the beam and slab. By increasing the inclined contact surface and using the auxiliary device's clamping splicing method, the vertical upright bearing node of the formwork support system under the inclined bottom surface of the beam and slab is transformed from a multi-directional unstable state to a vertically stable state, thereby realizing the vertical load transmission path of the inclined bottom surface formwork support.

[0004] In the existing solutions described above, the formwork support for the inclined bottom surface of beams and slabs uses a "support device" to ensure reliable load-bearing of the vertical uprights. However, this "support device" has a complex structure, poor environmental performance, and limited applicability. In actual on-site construction, due to its own structural limitations, this "support device" is difficult to meet the erection requirements for formwork support under the inclined bottom surface of large-area structural beams and slabs. Furthermore, the "support device" is large in size and weight, requiring manual assistance with mechanical hoisting for assembly during the formwork support system erection process, resulting in a slow installation process.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] like Figures 1-7 As shown, an auxiliary device for supporting a tilted bottom template includes two double-arch bridge blocks 1 and a triangular block 2. The double-arch bridge blocks 1 have square conical grooves 3 and two grooves 11. The two double-arch bridge blocks 1 are connected. The triangular block 2 is fixed with a tenon 4. The tenon 4 is inserted into one of the square conical grooves 3 for tenon-and-mortise connection. The triangular block 2 is provided with an inclined surface 12.

[0023] Based on the above scheme, in some embodiments, the two grooves 11 on the double arch bridge block 1 are arranged symmetrically along the central axis of the double arch bridge block 1.

[0024] In some embodiments, the groove 11 is semi-circular.

[0025] Regarding size selection: Optionally, the radius of the groove 11 is 24 mm.

[0026] Optionally, the double-arch bridge block 1 has a length of 2000mm, a width of 150mm, and a height of 50mm.

[0027] Optionally, the triangular block 2 has a length of 2000mm, a width of 150mm, and a height of 50-100mm.

[0028] Optionally, the materials of the double-arch bridge block 1, the triangular assembly block 2, and the tenon 4 all include cedar wood.

[0029] Optionally, the square groove 3 has a length of 50mm, a width of 50mm, and a height of 10mm, and the tenon 4 has a length of 50mm, a width of 50mm, and a height of 10mm.

[0030] Working principle: The double-arch bridge block 1 and the triangular block 2 are the main components of each individual structure in the auxiliary device. According to the design drawings and specifications, the inclined bottom structural beam and slab formwork support system can be assembled by mortise and tenon joints to meet the load-bearing requirements of the corresponding inclined bottom structure. Through the mortise and tenon joints of each individual piece, it is ensured that the top of each support pole 7 can be closely fitted with the concrete structure 8 by means of the structural features of the auxiliary device, and fully bear the force. This ensures the vertical single-path of the force transmission path of the concrete structure 8 of the inclined bottom beam and slab of each structure. At the same time, the double-groove form of the double-arch bridge block 1 can be used to clamp and position the steel pipe 5 to ensure that the steel pipe 5 does not undergo horizontal displacement due to external forces.

[0031] The square groove 3 and the tenon 4 are mainly used to achieve the mortise and tenon joint between them to support the inclined bottom formwork. The auxiliary device for supporting the top support of the inclined bottom formwork is used as a transition piece to transfer the construction load and self-weight load on the inclined bottom beam and slab concrete structure 8 in stages from the steel pipe 5 and the adjustable top support 6 of the disc-type steel pipe support to the uprights 7. This allows the formwork support system to bear the load vertically as a whole and achieves the leveling and positioning effect of each disc-type steel pipe support 6 of the formwork support system. This prevents the formwork from deforming, running out of formwork and bulging due to insufficient bearing capacity provided by the formwork support system during the pouring of the inclined bottom beam and slab concrete structure 8, which would have an adverse effect on the appearance quality, position and dimensional deviation of the cast-in-place structure and the structural strength performance test.

[0032] In a specific embodiment, the double-arch bridge block 1 and the triangular block 2 are first assembled into an inclined bottom formwork support top support auxiliary device by mortise and tenon joints with the corresponding positions of the square conical groove 3 and the splicing tenon 4. Then, according to the requirements of the formwork support system erection sequence, the uprights 7, horizontal bars 9, vertical diagonal bars 10 and the adjustable top support 6 of the disc-lock steel pipe bracket are installed one by one. After the basic formwork support frame is erected, the double steel pipes 5 are erected on each of the adjustable top supports 6 of the disc-lock steel pipe bracket. The double grooves 11 in the inclined bottom formwork support top support auxiliary device position and anchor the double steel pipes 5 in the inclined bottom formwork support top support auxiliary device. Then, by adjusting the extension length of the adjustable top support 6 of the disc-lock steel pipe bracket, the inclined bottom formwork support top support auxiliary device and the inclined bottom formwork of the structural beam and slab are pressed tightly together, so that the formwork support system under the inclined bottom of the structure forms an independent and stable whole.

[0033] like Figure 7 This is a schematic diagram of the application of an inclined bottom formwork support top support device. First, based on the design slope requirements of the inclined bottom surface of the building's structural beams and slabs, an inclined bottom formwork support top support device composed of double arch bridge blocks 1 and triangular blocks 2 with mortise and tenon joints is selected. After the formwork support components are installed and connected to each other, the double steel pipes 5 are positioned and anchored along the built-in double grooves in the inclined bottom formwork support top support device. Then, by adjusting the extension length of the adjustable top support 6 of the disc-type steel pipe bracket, the inclined bottom formwork support top support device and the inclined bottom formwork of the structural beams and slabs are pressed tightly together. Finally, after the concrete strength of the upper beams and slabs reaches the required demolding strength according to the specifications, the beams and slabs formwork support system and each component of the inclined bottom formwork support top support device can be removed one by one and reused in the next stage of inclined bottom formwork support.

[0034] A method for supporting an inclined bottom formwork, based on the aforementioned inclined bottom formwork support top support auxiliary device, includes the following steps: Set the horizontal control elevation; Install vertical support pole 7; The beams and slabs are vertically supported on the uprights 7. The main keel of the beam bottom is erected on the double steel pipe 5 on the disc-lock steel pipe support and the adjustable top support 6 of the disc-lock steel pipe support; The auxiliary device is mounted on the main keel double steel pipe 5; Install the bottom and side formwork of the beam; The main keel of the slab bottom is erected on the double steel pipe 5 on the adjustable top support 6 of the disc-lock steel pipe support; The auxiliary device is mounted on the main keel double steel pipe 5; Floor slab formwork installation; The template support system has passed acceptance testing. Reinforcement binding for beams and slabs; 8. Pour concrete for beams and slabs; Curing of concrete 8; Remove the floor slab formwork; Panasonic disc-lock steel pipe support, adjustable top support; 6. Remove the auxiliary device. Remove beam and slab formwork and clean the formwork. Remove the vertical supports, horizontal bars 9, and adjustable top supports 6 of the disc-lock steel pipe scaffold.

[0035] Preferably, the vertical support of the beam and slab includes horizontal tie rods, vertical diagonal braces 10, and scissor braces.

[0036] In this technology, the double-arch bridge block 1 and the triangular block 2 in the inclined bottom formwork support top support auxiliary device are first assembled with mortise and tenon joints to form an inclined bottom formwork support top support auxiliary device that meets the corresponding design slope. Placing it on the adjustable top support 6 can form an independent and stable support. While ensuring full force bearing in contact with the inclined bottom surface of the beam and slab, it can also constrain the oblique construction load transmission of the inclined bottom surface of the beam and slab, ensuring that the top of the formwork support system is in a unidirectional vertical force state, and preventing the top of the formwork support from eccentric overturning due to the influence of lateral forces.

[0037] The double grooves built into the top support auxiliary device supported by the inclined bottom template are used to fix the double steel pipes 5 in place, ensuring that the double steel pipes 5 do not slide or shift on their own when disturbed or subjected to uneven force, thus ensuring the overall stability of the double steel pipes 5 as the main load-bearing keel.

[0038] It effectively realizes the overall stability and load-bearing capacity of the formwork support system under the inclined bottom surface of the structural beam and slab, and achieves high precision and high quality in the detection of beam and slab structural dimensions and performance.

[0039] Beneficial effects of this invention: This invention utilizes an auxiliary device for supporting the inclined bottom formwork to achieve vertical load transfer at the top bearing nodes of the vertical uprights of the formwork support system under the inclined bottom surface, ensuring overall stability and preventing overturning. It can meet the safety bearing requirements of formwork support erection and installation for structural beams and slabs with different inclinations under various environmental categories. It effectively saves construction labor and material costs while ensuring the construction quality of inclined bottom structural beams and slabs, improving the first-time pass rate of inclined bottom structural beams and slab construction. It is an auxiliary device with good economic efficiency, construction efficiency, and simple manufacturing.

[0040] The components, modules, mechanisms, and devices in this invention that are not described in detail are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
