Description

Technical Field

[0001] This invention relates to the field of building technology, specifically to an auxiliary device and support method for a large-slope formwork support combination base. Background Technology

[0002] During the construction of the main structure, the sloping floor has a natural difference in horizontal slope, which causes the formwork support system to face core problems such as uneven foundation bearing capacity, excessive horizontal thrust, and difficulty in controlling overall stability. Conventional vertical ground support technology cannot be directly applied.

[0003] Currently, a utility model patent for "an auxiliary device for erecting a template support frame on an inclined surface" has been found. This "auxiliary device" includes multiple base plates installed on the inclined surface. Each base plate has a load-bearing body fixed on its top. A sleeve is ball-jointed to the top of the load-bearing body. A limiting component is provided on the load-bearing body to prevent the sleeve from rotating. A vertical pole is inserted above the sleeve. The template support frame is installed on the top of the vertical pole. The aspect most similar to the present application is the method of adjusting the uprights of the formwork support system to be perpendicular to the support surface. The existing solution uses a positioning screw to pass through a base plate with a rubber anti-slip pad and then locks the nut to fix it to the inclined surface to form a firm anchor point. The upper load-bearing body is connected to the formwork support upright through a ball joint sleeve and matching limiting parts. The verticality of the upright is adjusted by rotating the sleeve, so that the formwork support upright can adjust the overall stress of the formwork support system according to the slope of the floor, thereby improving its own stability and the quality of the top slab project. The present application solution is to embed and install a large-slope formwork support combined base auxiliary device at the bottom of the large-slope formwork support upright. By pre-embedding steel pipes to anchor the base layer and connecting and splicing the base, the formwork support upright located on the inclined floor can be directly placed on the flat surface formed by the auxiliary device, so that the formwork support system has a horizontal force-bearing foundation on the inclined surface and realizes the vertical force transmission of the large-slope formwork support.

[0004] In the existing solutions described above, the verticality of the uprights in the formwork support system to the support surface is achieved using an "auxiliary device" to ensure the vertical force transfer of the formwork support on steep slopes. However, this "auxiliary device" is complex in construction, lacks overall integrity, and involves cumbersome procedures. In actual on-site construction, because this "auxiliary device" is independently installed and fixed on the sloping floor, the verticality adjustment of each upright must be done manually, making it difficult to ensure the overall vertical stability of the formwork support system. Furthermore, due to its inherent structural limitations, the range of verticality adjustment via sleeve rotation is limited, making it unsuitable for floors with steep slopes. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention aims to provide an auxiliary device and support method for a combined base of templates with steep slopes. To solve these problems, this invention employs the following technical solution: A large-slope template support combination base auxiliary device includes a ladder-shaped module A, a ladder-shaped module B and a ladder-shaped module C, wherein the ladder-shaped module B is provided with two or more. Trapezoidal module A, trapezoidal module B, and trapezoidal module C are all in the shape of right-angled trapezoids; Both the side wall of the trapezoidal module B and the side wall of the trapezoidal module C have connecting recesses. Both trapezoidal module A and trapezoidal module B have embedded blocks fixedly connected to their side walls. The embedded block on the side wall of the trapezoidal module A is inserted into the connecting recess on the side wall of the trapezoidal module B for mortise and tenon connection. The embedded block on one trapezoidal module B is inserted into the connecting recess on the side wall of the adjacent trapezoidal module B for mortise and tenon connection. The other trapezoidal modules B are connected in the same way. The embedded block on the side wall of one trapezoidal module B is inserted into the connecting recess on the side wall of the trapezoidal module C for mortise and tenon connection.

[0006] Optionally, it may also include four or more adjustment modules D, each of which is in the shape of a right trapezoid and has an embedded block fixed to its bottom wall; Connecting recesses are provided on the top walls of the trapezoidal module A, the trapezoidal module B, and the trapezoidal module C; The embedded block is inserted into the connecting recess on the top wall of the trapezoidal module A, the connecting recess on the top wall of the trapezoidal module B, or the connecting recess on the top wall of the trapezoidal module C for mortise and tenon connection.

[0007] Optionally, the ladder-shaped module A has a left side length of 200mm, a right side length of 100mm, a left and right width of 200mm, and a front and back thickness of 200mm.

[0008] Optionally, the trapezoidal module B has a left length of 200mm, a right length of 100mm, a left and right width of 200mm, and a front and back thickness of 200mm.

[0009] Optionally, the trapezoidal module C has a left length of 200mm, a right length of 100mm, a left and right width of 200mm, and a front and back thickness of 200mm.

[0010] Optionally, the adjustment module D has a left length of 50mm, a right length of 100mm, a left and right width of 200mm, and a front and back thickness of 200mm.

[0011] Optionally, the materials of the ladder-shaped module A, ladder-shaped module B, ladder-shaped module C, adjustment module D, and embedded block all include cedar wood.

[0012] Optionally, the embedded block is cubic in shape, with a length, width, and height of 50mm, and the connecting recess is cubic in shape, with a length, width, and height of 50mm.

[0013] A method for supporting formwork with a large slope, based on the aforementioned auxiliary device for a combined base of formwork supports with a large slope, includes the following steps: Step 1: An auxiliary device is formed to connect the ladder-shaped modules A, B, and C. The embedded block on the side wall of ladder-shaped module A is inserted into the connecting recess on the side wall of ladder-shaped module B to form a mortise and tenon connection. The embedded block on one ladder-shaped module B is inserted into the connecting recess on the side wall of the adjacent ladder-shaped module B to form a mortise and tenon connection. The other ladder-shaped modules B are connected in the same way. The embedded block on the side wall of one ladder-shaped module B is inserted into the connecting recess on the side wall of ladder-shaped module C to form a mortise and tenon connection. Step 2: Place the auxiliary device on a concrete structure with a certain slope; Step 3: The anti-lateral displacement module is placed into each of the pre-embedded steel pipes one by one according to the cavity positions set by itself, forming a reliable horizontal support reaction support. The horizontal support reaction support and the auxiliary device fit together. Step 4: Place each vertical support pole on the installed auxiliary device according to the spacing requirements of the formwork support system. Step 5: Install the longitudinal and transverse horizontal tie rods, vertical diagonal braces, and scissor braces one by one to form an independent and stable beam and slab formwork support system. Finally, after the concrete strength of the upper beam and slab structure reaches the specification requirements and the demolding strength is achieved, the beam and slab formwork support system and auxiliary devices can be removed one by one and reused in the next stage of large slope formwork support.

[0014] Optionally, step one may also include: Connection of adjustment module D: Each tiered module A, tiered module B, and tiered module C is connected to adjustment module D by inserting the embedded block on adjustment module D into the connecting recess on the top wall of tiered module A, the connecting recess on the top wall of tiered module B, or the connecting recess on the top wall of tiered module C for mortise and tenon connection.

[0015] The present invention has the following beneficial effects: Firstly, the trapezoidal modules A, B, and C, along with the adjusting module D, are joined together using mortise and tenon joints to form a large-slope formwork support base auxiliary device. This device provides a horizontal base for the formwork support system under different slopes. Simultaneously, it ensures that the vertical support poles provide simple force transmission to the upper beam and slab structure, offering vertical unidirectional support. Then, by embedding steel pipes and nesting anti-lateral displacement modules, a reliable horizontal support reaction seat is formed to constrain the large-slope formwork support base auxiliary device from overturning displacement caused by the horizontal force of the structural slope and its own weight. This effectively achieves the overall stable load-bearing function of the beam and slab formwork support system and ensures high precision and high quality in the detection of the upper beam and slab structure dimensions and performance.

[0023] like Figures 1-8 As shown, an auxiliary device for a large-slope template support combination base includes a tiered module A1, a tiered module B2, and a tiered module C3, wherein the tiered module B2 has two or more components. Trapezoidal module A1, trapezoidal module B2, and trapezoidal module C3 are all in the shape of right-angled trapezoids; Both the sidewall of the trapezoidal module B2 and the sidewall of the trapezoidal module C3 are provided with connecting recesses 6; Both trapezoidal module A1 and trapezoidal module B2 have embedded blocks 5 fixedly connected to their side walls. The embedded block 5 on the side wall of the trapezoidal module A1 is inserted into the connecting recess 6 on the side wall of the trapezoidal module B2 for mortise and tenon connection. The embedded block 5 on one of the trapezoidal modules B2 is inserted into the connecting recess 6 on the side wall of the adjacent trapezoidal module B2 for mortise and tenon connection. The other trapezoidal modules B2 are connected in the same way. The embedded block 5 on the side wall of one of the trapezoidal modules B2 is inserted into the connecting recess 6 on the side wall of the trapezoidal module C3 for mortise and tenon connection.

[0024] According to an optional embodiment of the present invention, it further includes four or more adjustment modules D4, each of which is in the shape of a right trapezoid and has an embedded block 5 fixedly connected to its bottom wall. Connecting recesses 6 are provided on the top walls of the trapezoidal module A1, the trapezoidal module B2, and the trapezoidal module C3; The embedded block 5 is inserted into the connecting recess 6 on the top wall of the trapezoidal module A1, the connecting recess 6 on the top wall of the trapezoidal module B2, or the connecting recess 6 on the top wall of the trapezoidal module C3 for mortise and tenon connection.

[0025] Optionally, the ladder-shaped module A1 has a left side length of 200mm, a right side length of 100mm, a left and right width of 200mm, and a front and back thickness of 200mm.

[0026] Optionally, the ladder-shaped module B2 has a left side length of 200mm, a right side length of 100mm, a left and right width of 200mm, and a front and back thickness of 200mm.

[0028] Optionally, the adjustment module D4 has a left side length of 50mm, a right side length of 100mm, a left and right width of 200mm, and a front and back thickness of 200mm.

[0029] Optionally, the ladder-shaped module A1, ladder-shaped module B2, ladder-shaped module C3, adjustment module D4, and embedding block 5 are all made of cedar wood.

[0030] Optionally, the embedding block 5 is cube-shaped, with a length, width, and height of 50mm, and the connecting recess 6 is cube-shaped, with a length, width, and height of 50mm.

[0031] like Figure 9 As shown, a method for supporting formwork with a large slope, based on the aforementioned auxiliary device for a combined base of formwork support with a large slope, includes the following steps: Step 1: An auxiliary device is formed to connect the trapezoidal modules A1, B2, and C3. The embedded block 5 on the side wall of trapezoidal module A1 is inserted into the connecting recess 6 on the side wall of trapezoidal module B2 for mortise and tenon connection. The embedded block 5 on one of the trapezoidal modules B2 is inserted into the connecting recess 6 on the side wall of the adjacent trapezoidal module B2 for mortise and tenon connection. The other trapezoidal modules B2 are connected in the same way. The embedded block 5 on the side wall of one of the trapezoidal modules B2 is inserted into the connecting recess 6 on the side wall of trapezoidal module C3 for mortise and tenon connection. Step 2: Place the auxiliary device on the concrete structure 8 with a certain slope; Step 3: The anti-lateral displacement module 10 is placed into each of the pre-embedded steel pipes 9 one by one according to the cavity positions set therein, forming a reliable horizontal support reaction support. The horizontal support reaction support and the auxiliary device fit together. Step 4: Place each vertical support pole 7 on the installed auxiliary device according to the spacing requirements of the template support system. Step 5: Install the longitudinal and transverse horizontal tie rods, vertical diagonal braces, and scissor braces one by one to form an independent and stable beam and slab formwork support system. Finally, after the concrete strength of the upper beam and slab structure reaches the specification requirements and the demolding strength is achieved, the beam and slab formwork support system and auxiliary devices can be removed one by one and reused in the next stage of large slope formwork support.

[0032] Preferably, step one also includes: Connection of adjustment module D4: Each tiered module A1, tiered module B2, and tiered module C3 is connected to adjustment module D4. The embedded block 5 on adjustment module D4 is inserted into the connecting recess 6 on the top wall of tiered module A1, the connecting recess 6 on the top wall of tiered module B2, or the connecting recess 6 on the top wall of tiered module C3 for mortise and tenon connection.

[0033] Working principle: like Figures 1-8 The diagram shows an auxiliary device for a large-slope formwork support combination base. The ladder-shaped module A1, ladder-shaped module B2, ladder-shaped module C3 and adjustment module D4 are the main components of each individual structure in the auxiliary device.

[0034] According to the design drawings and specifications, the irregular concrete structure 8 can be constructed by mortise and tenon joints to form a beam and slab formwork support system base that meets the overall stability and vertical bearing capacity under the corresponding slope conditions. Through the nesting of each component, it is ensured that the bottom of each vertical support pole 7 will not tilt or shift independently under the influence of the inclination angle of the concrete structure 8 itself, thanks to the planar stability provided by the auxiliary device, thus ensuring the simple unidirectional downward force transmission of each irregular beam and slab concrete structure 8.

[0035] The embedded block 5 and the connecting recess 6 are mainly used to achieve the joint support of the template support system base on the irregular concrete structure 8 through their closed connection, and to achieve the precise positioning effect of each vertical support rod 7 of the template support system. This prevents the beam and slab concrete structure 8 from tilting and shifting due to the overturning horizontal force of the concrete structure 8 and the self-weight of the template support system during the pouring process, which would cause quality defects such as honeycomb surface and misalignment in the beam and slab concrete structure 8, and negatively affect the flatness, verticality, load-bearing reliability and structural performance testing of the structural base. The pre-embedded steel pipe 9 and the anti-lateral displacement module 10 are mainly used to constrain displacement and provide reverse horizontal support for the auxiliary device of the large slope template support combination base. The pre-embedded steel pipe 9 and the anti-lateral displacement module 10 are nested together to cancel out the lateral horizontal forces on each individual unit in the auxiliary device of the large slope template support combination base.

[0036] Implementation process: First, the ladder-shaped modules A1, B2, and C3 are respectively connected one by one through their own embedding blocks 5 and connecting recesses 6 to form a large slope template support combination base auxiliary device, which is then placed on a concrete structure 8 with a certain slope.

[0037] Depending on the slope of the site structure, it may be necessary to add an adjustment module D4 to meet the horizontal requirements of the support base. Then, the anti-lateral displacement module 10 is placed into each pre-embedded steel pipe 9 along each cavity position to form a reliable horizontal support reaction support. After that, each vertical support pole 7 is placed on the auxiliary device of the large slope formwork support combination base according to the support system layout interval requirements. Then, longitudinal and transverse horizontal tie rods, vertical diagonal rods and scissor braces and other supporting turnover materials are installed one by one to form an independent and stable beam and slab formwork support system.

[0038] like Figure 9 As shown, based on the slope of the concrete structure 8 at the construction site, a large-slope formwork support combination base auxiliary device foundation is selected, consisting of interlocking trapezoidal modules A1, B2, and C3. Alternatively, tiered modules A1, B2, and C3, together with adjustment module D4, can be assembled using mortise and tenon joints to form a progressive auxiliary device for a large-slope template support base. Next, the anti-lateral displacement module 10 is placed into each pre-embedded steel pipe 9 along each cavity position to form a reliable horizontal support reaction support that fits tightly with the large slope formwork support combination base auxiliary device. Then, each vertical support pole 7 is placed on the large slope formwork support combination base auxiliary device one by one. Then, the longitudinal and transverse horizontal tie rods, vertical diagonal rods and scissor braces and other supporting turnover materials are installed one by one to form an independent and stable beam and slab formwork support system. Finally, after the concrete strength of the upper beam and slab structure reaches the standard requirement for demolding strength, the beam and slab formwork support system and each component of the large slope formwork support combination base auxiliary device can be removed one by one and reused in the next large slope formwork support stage.

[0039] The preferred construction procedure is as follows: Pre-embed the steel pipe 9 → Determine the horizontal control elevation → Assemble the large-slope formwork support base auxiliary device on the structural slope → Nest the anti-lateral displacement module 10 with the pre-embedded steel pipe 9 → Install the vertical support pole 7 → Install the vertical support for the beam and slab (including longitudinal and transverse horizontal tie rods, vertical diagonal rods, and scissor braces) → Erect the main keel double steel pipe of the beam bottom onto the top support plate of the disc-lock steel pipe bracket → Erect the secondary keel timber of the beam bottom onto the main keel double steel pipe → Install the beam bottom formwork and side formwork → Erect the main keel double steel pipe of the slab bottom On the top support plate of the disc-lock steel pipe scaffold → erect the secondary keel timber on the main keel double steel pipe → floor slab formwork installation → formwork support system passes acceptance → beam and slab reinforcement binding → beam and slab concrete pouring → concrete curing → formwork removal approved by the supervisor before demolding → pine disc-lock steel pipe scaffold adjustable top support → remove beam and slab formwork, clean the formwork → remove horizontal tie rods, vertical diagonal rods, scissor braces and disc-lock steel pipe scaffold → large slope formwork support combination base auxiliary device, anti-lateral displacement module 10 and cut off the embedded steel pipe 9, structural repair.

[0040] In this technology, the trapezoidal modules A1, B2, and C3, along with the adjustment module D4, are interlocked in a mortise and tenon joint to form a large-slope formwork support base auxiliary device. This device provides a horizontal base for the formwork support system under different slopes. Simultaneously, it ensures that the vertical support poles 7 provide simple force transmission for the upper beam and slab structure, offering vertical unidirectional support. Then, a reliable horizontal support reaction seat is formed by the nesting of pre-embedded steel pipes 9 and anti-lateral displacement modules 10, thus constraining the large-slope formwork support base auxiliary device from overturning displacement caused by the horizontal force of the structural slope and its own weight. This effectively achieves the overall stable load-bearing function of the beam and slab formwork support system and ensures high precision and high quality in the detection of the upper beam and slab structure dimensions and performance.
