Description

Technical Field

[0001] This utility model belongs to the field of support systems, and in particular relates to a beam and slab formwork support system. Background Technology

[0002] In current construction projects, large-section, oversized beams and slabs are increasingly used to meet diverse functional requirements. Due to their heavy weight, these components require formwork support and reinforcement systems to withstand greater positive pressure and unbalanced forces during the pouring process. Typically, the support system uses main ribs to transfer and distribute vertical loads. However, existing main ribs lack effective reinforcement measures at the joints, leading to reduced load-bearing capacity at these locations and increased susceptibility to deformation. This results in deflection at the corresponding location after concrete pouring. Furthermore, it significantly increases the bending moment load on the columns surrounding the joints, affecting the overall balance, stability, and safety of the formwork support system. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a beam and slab formwork support system, which avoids the insufficient bearing capacity at the joint of the main support beam, ensures the overall support system is stress-balanced, and improves the integrity and stability of the support system.

[0004] The technical solution adopted by this utility model is: a beam and slab formwork support system, including formwork and timber, and further including a main support rib and a reinforcing rib set at the bottom of the timber. Two main support ribs are joined together to form a joint. Column assemblies are symmetrically arranged on both sides of the joint. The main support rib and the reinforcing rib are arranged side by side on the top of the column assemblies.

[0005] Furthermore, the joint portions are staggered along the length of the component to be constructed, and there is only one joint portion between the two column assemblies.

[0006] Furthermore, both ends of the reinforcing rib are respectively connected to the column assembly.

[0007] Furthermore, the diameter of the reinforcing rib is the same as that of the supporting main rib.

[0008] Furthermore, the reinforcing ribs and other supporting main ribs are disposed on both sides of the two mating supporting main ribs.

[0009] Furthermore, the column assembly includes a reinforcing top support, which includes a limiting groove for accommodating the main supporting rib and the reinforcing rib.

[0010] Furthermore, the width of the limiting groove is adapted to the sum of the diameters of the main supporting rib and the reinforcing rib.

[0011] Furthermore, the column assembly also includes a column detachably connected to the reinforcing top support, the axis of the column being aligned with the center of the limiting groove.

[0012] Furthermore, the reinforcing top support also includes a reinforcing member and a connecting member. The connecting member is disposed at the bottom of the limiting groove and is threadedly connected to the column. The reinforcing member is connected to the bottom of the limiting groove and the connecting member respectively.

[0013] The advantages and positive effects of this utility model are:

[0014] (1) By setting up reinforcing ribs, the reinforcing ribs and the main supporting ribs are set side by side on the top of the column assembly, so that the reinforcing ribs can provide stable support for the upper timber, make up for the defect of insufficient bearing capacity at the joint, and avoid the phenomenon of deflection at this part; and can evenly distribute the vertical load to the column assembly on both sides, ensuring the overall support system is balanced, improving the integrity and stability of the support system, and effectively avoiding the occurrence of safety accidents.

[0015] (2) By setting the reinforcing ribs and the other supporting main ribs along the length on both sides of the connecting supporting main ribs, local overload can be effectively avoided, which is conducive to improving the overall load-bearing capacity of the support system.

[0016] (3) By setting up reinforced top supports and reinforced ribs, the formwork support system is always supported by the continuous main support ribs or the continuous main support ribs and reinforced ribs along the length of the main support ribs, which improves the balance and continuity of the force of the formwork support system and further ensures the stability and safety of the formwork support system.

[0021] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0022] like Figure 1 , Figure 2As shown, this utility model proposes a beam and slab formwork support system to solve the problem of insufficient load-bearing capacity of the main ribs at the joint 31 in the existing beam and slab formwork support system. By rationally designing the force-bearing system, the overall load-bearing capacity, balance and stability of the formwork support system are improved.

[0023] like Figure 1 , Figure 2 As shown, this application provides a beam and slab formwork support system, including a formwork 1, a timber 2, main support ribs 3, reinforcing ribs 4, and column assemblies 5; the main support ribs 3 and the reinforcing ribs 4 are arranged at the bottom of the timber 2; two main support ribs 3 are joined together to form a joint 31, and column assemblies 5 are symmetrically arranged on both sides of the joint 31, and the main support ribs 3 and the reinforcing ribs 4 are arranged side by side at the top of the column assemblies 5.

[0024] The template 1 is used to shape the beam and slab components to be constructed, so that the hardened concrete has the shape and size required by the design. In this embodiment, the template 1 is set at the bottom of the component to be constructed. The timber 2 is evenly set at the bottom of the template 1 to form a balanced and stable support for the template 1. The main support rib 3 and the reinforcing rib 4 are used to support the timber 2 and distribute the vertical load along its length direction to the column assembly 5. The column assembly 5 is erected on the ground to form a stable support for the template 1, timber 2, main support rib 3 and reinforcing rib 4 above it.

[0025] In this application, the timber beam 2, the main supporting rib 3, and the reinforcing rib 4 are all strip-shaped components. The main supporting rib 3 and the reinforcing rib 4 are arranged perpendicular to the timber beam 2. Normally, the main supporting rib 3 has a predetermined length. When the size of the component to be constructed is large, the main supporting rib 3 needs to be joined end-to-end to meet the support requirements, inevitably forming the joint portion 31 in this application. In the prior art, the main supporting rib 3 is supported by several top support components. However, since the joint portion 31 is suspended, its load-bearing capacity is low, constituting a weak link in the support. This application, by setting the reinforcing rib 4, arranges it side-by-side with the main supporting rib 3 on top of the column assembly 5. The reinforcing rib 4 provides stable support for the upper timber beam 2, compensating for the insufficient load-bearing capacity of the joint portion 31 and preventing sagging. It also evenly distributes the vertical load to the column assemblies 5 on both sides, ensuring a balanced force on the overall support system, improving the integrity and stability of the support system, and effectively preventing safety accidents.

[0026] The joint portion 31 mentioned above is staggered along the length of the component to be constructed, and there is only one joint portion 31 between the two column components 5. By staggering the joint portion 31, too many joints in the same position can be avoided, thereby avoiding a significant decrease in load-bearing capacity due to too many joints, which is conducive to improving the overall load-bearing capacity and seismic performance. There is only one joint portion 31 between the two column components 5, which simplifies the stress situation between the two column components 5 and helps to ensure that the reinforcing rib 4 can provide sufficient support.

[0027] The two ends of the aforementioned reinforcing rib 4 are respectively connected to the column assembly 5; preferably, the length of the reinforcing support is such that it can extend to the opposite outer sides of the two column assemblies 5 to ensure a stable connection between the reinforcing rib 4 and the column assembly 5.

[0028] In one specific embodiment, the diameter of the reinforcing rib 4 is the same as that of the supporting main rib 3, so as to ensure that the top and bottom of the reinforcing rib 4 and the supporting main rib 3 are at the same height, forming effective support; the reinforcing rib 4 is preferably made of the same material and specifications as the supporting main rib 3, or a portion of the length of the supporting main rib 3 is cut off to form the reinforcing rib 4, which is convenient for processing and manufacturing.

[0029] In this application, the number of main supporting ribs 3 can be set as needed, and is usually designed to be no less than two. The main supporting ribs 3 located on the two column assemblies 5 include two butt-jointed main supporting ribs 3 and other main supporting ribs 3 that run the length of the column. The reinforcing ribs 4 and other main supporting ribs 3 are set on both sides of the two main supporting ribs 3 that are aligned and connected. This design places the joint 31 in the middle, which can balance the force on both sides and avoid stress concentration on one side, thereby improving the overall stability of the structure. The reinforcing ribs 4 and other main supporting ribs 3 are all set the length of the column between the two column assemblies 5, which can distribute the load more evenly when under stress, avoid local overload, and help improve the overall load-bearing capacity of the support system. In addition, this design is more convenient for workers to carry out construction and avoid confusion.

[0030] In one specific embodiment, each column assembly 5 is provided with two main support ribs 3 and one reinforcing rib 4. One of the main support ribs 3 is connected to the main support rib 3 on the other column assembly 5 in the longitudinal direction to form a joint portion 31. The other main support rib 3 is arranged along the length between the two column assemblies 5. The two connected main support ribs 3 are located between the reinforcing rib 4 and the main support rib 3 arranged along the length.

[0031] The column assembly 5 in this application includes a reinforcing top support 51, which includes a limiting groove 511 for accommodating the main support 3 and the reinforcing support 4, so as to limit the main support 3 and the reinforcing support 4 and prevent them from shifting their positions during use.

[0032] Specifically, the limiting groove 511 includes a side wall and a supporting base plate. The width of the limiting groove 511 is adapted to the sum of the diameters of the supporting main rib 3 and the reinforcing rib 4, so that the supporting main rib 3 and the reinforcing rib 4 located in the limiting groove 511 abut against each other, forming an effective limiting of the supporting main rib 3 and the reinforcing rib 4.

[0033] The column assembly 5 in this application also includes a column 52 detachably connected to the reinforcing top support 51. The axis of the column 52 is aligned with the center of the limiting groove 511. Since the supporting main rib 3 is located in the middle of the reinforcing top support 51, this design enables the axis of the column 52 to be aligned with the supporting main rib 3, thereby maximizing the balance of force on each part of the reinforcing top support 51 and avoiding eccentric force that could affect the stability of the column 52.

[0034] The reinforcing top support 51 also includes a reinforcing member 512 and a connecting member 513. The connecting member 513 is disposed at the bottom of the limiting groove 511 and is threadedly connected to the column 52. The reinforcing member 512 is connected to the bottom of the limiting groove 511 and the connecting member 513 respectively. The reinforcing member 512 forms a support for the limiting groove 511, which can effectively prevent the reinforcing top support 51 from deforming and enhance the strength of the reinforcing top support 51. Specifically, the reinforcing member 512 in this application is a triangular steel plate, and the two right-angled sides of the triangle are connected to the bottom of the limiting groove 511 and the connecting member 513 respectively.

[0035] In this application, several conventional top supports are also provided along the length of the main support rib 3, and reinforced top supports 51 are provided on both sides of the joint 31. Due to the setting of the reinforced support rib 4, the supporting base plate of the reinforced top support 51 is larger than that of the conventional top support. By setting conventional top supports and reinforced top supports 51, the upper load of the formwork support system is always borne by the continuously installed main support rib 3 or the continuously installed main support rib 3 and reinforced support rib 4 along the length of the main support rib 3, which improves the balance and continuity of the force of the formwork support system and ensures the stability and safety of the formwork support system.

[0036] The construction method for the beam and slab formwork support system proposed in this application includes the following steps:

[0037] S1. Design and verify the template support system;

[0038] Through design and calculation, the positions of the main support rib 3, the joint 31, the column 52, and the length of the reinforcing support rib 4 were determined.

[0039] S2. Calculate and determine the cross-sectional dimensions of the reinforcing top support 51;

[0040] Based on the vertical load transmitted by the main support rib 3 and the reinforcing support rib 4 borne by the reinforced top support 51, the supporting base plate of the limiting groove 511 is designed. The width of the supporting base plate is equal to the sum of the diameters of the main support rib 3 and the reinforcing support rib 4 it supports. Thus, the length of the supporting base plate can be determined through stress calculation to meet the bearing capacity requirements of the reinforced top support 51.

[0041] S3. Calculate the dimensions of the reinforcing member 512; calculate the dimensions of the reinforcing member 512 based on the dimensions of the limiting groove 511 and the load conditions.

[0042] S4. Construct a reinforced top support 51;

[0043] S5. Install reinforcing top supports 51 on the upper ends of the columns 52 on both sides of the joint 31 supporting the main beam 3.

[0044] Install the template support system, set up columns 52 according to the designed distance, and install conventional top supports and reinforced top supports 51 on the columns 52. The reinforced top supports 51 are installed on the columns 52 on both sides of the joint 31, and the conventional top supports are installed on the columns 52 in other parts.

[0045] S6. Install the main support beam 3 and the reinforcing support beam 4.

[0046] First, install the main support ribs 3. In this embodiment, the main support ribs 3 are arranged in two rows, and each row of main support ribs 3 includes several main support ribs 3 that are connected in the length direction. First, install the two main support ribs 3 to be connected on the reinforcing top support 51, and then install the reinforcing support rib 4 and another main support rib 3 on both sides of the connected main support ribs 3 respectively.

[0047] This application, by setting up reinforcing ribs, places them side-by-side with the main support ribs at the top of the column assembly. This allows the reinforcing ribs to provide stable support for the upper timber, compensating for insufficient load-bearing capacity at the joint and preventing sagging in that area. It also evenly distributes the vertical load to the column assemblies on both sides, ensuring balanced stress on the overall support system, improving its integrity and stability, and effectively preventing safety accidents. Placing the continuous reinforcing ribs and another continuous main support rib on either side of the joined main support ribs effectively prevents localized overload and improves the overall load-bearing capacity of the support system. By setting up reinforcing top supports and reinforcing ribs, the formwork support system ensures that the upper load is always borne by the continuous main support ribs or a combination of continuous main support ribs and reinforcing ribs along the length of the main support ribs, improving the balance and continuity of stress on the formwork support system and further ensuring its stability and safety.
