Description

Technical Field

[0001] The present invention belongs to the field of stools for reinforcing bars, and particularly relates to a completely prefabricated concrete slab stool for reinforcing bars. Background Art

[0002] With the rapid development of the construction industry in China, reinforced concrete structures have been widely used in engineering practice. Reinforcing bars play a very important role in the construction process and are known as the "skeleton" of the structure, directly affecting the bearing capacity and stability of the structure. During the process of casting in-situ reinforced concrete slabs, it is necessary to lift the upper steel bar mesh to ensure that the concrete evenly covers the floor slab, and it is also necessary to bear the impact load and the live load of the crowd during pouring. This requires that the lower support of the steel bar mesh has sufficient strength and good stability to ensure safety during the construction process. The measures taken during the construction process are usually to set stools for reinforcing bars (commonly known as "iron horses") under the upper structural steel bar mesh to bear the upper load and ensure the stability of the structure. There are many forms of stools for reinforcing bars, such as "several"-shaped, bench-shaped, precast concrete stools, etc. However, during the construction process, a large amount of manpower is usually required to install the stools for reinforcing bars, and it is necessary to fix them together with the lower steel bar mesh by binding, welding, etc. This will increase the steel consumption, increase the self-weight of the floor slab, waste resources seriously, consume time and labor, and more seriously, it will slow down the overall construction progress of the project, and cannot well ensure the stability of the overall structure and the workload is large. In addition, the installation quality cannot be well guaranteed, and multiple inspections are required to ensure safety. In recent years, the tree structure has been favored by engineering designers. The tree structure is a complex spatial rigid frame system with clear force flow, reasonable force transmission, and beautiful shape. It is a bionic structure integrating shape bionics and structure bionics, and can be applied to structural engineering such as large amusement parks, cultural venues, airport buildings, and waiting platforms.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0029] like Figures 1 to 3 As shown in the figure, a fully assembled concrete slab horse stool reinforcement is used. This structure is optimized by the general finite element software ANSYS. The length of each bar and the angle of each node can be accurately obtained.

[0030] A fully assembled concrete slab saddle reinforcement is a tree-like structure saddle reinforcement, which provides better stability and is placed between the steel bar spacings at the bottom of the concrete slab.

[0031] The overall structure of the horse stool reinforcement in this application is made of PVC material, which has a certain elasticity, so that the steel bar can be stuck into the inside of the groove and is not easy to slide out. However, it is not limited to PVC material. Any material with the characteristics of light weight, economy, environmental protection, sufficient strength, and easy production can be used as source material.

[0032] like Figures 1 to 3 As shown, a fully assembled concrete slab horse stool reinforcement includes a main support leg 1, a main connecting head 2, a sub-support leg and a base 3;

[0033] The diameter of the main support leg 1 should be smaller than the spacing of the steel bars at the bottom of the concrete slab, and its height should be equal to the thickness of the protective layer of the concrete slab.

[0034] The main support leg 1 is located at the top of the entire device and is connected to a single steel bar of the upper steel mesh.

[0035] The main supporting leg 1 is connected to the sub-supporting leg through a main connecting head 2. There are multiple sub-supporting legs. The bottom of the sub-supporting leg is detachably connected to the base 3, and the top of the sub-supporting leg is detachably connected to the main connecting head 2. The main supporting leg 1 is detachably arranged on the upper end of the main connecting head 2, and the tops of multiple sub-supporting legs are connected to the same main connecting head 2.

[0036] The sub-supporting legs include a first sub-supporting leg 4, a sub-connecting head 5, and a second sub-supporting leg 6;

[0037] A first slot 401 for mounting the first branch support leg 4 is provided at the bottom of the main connector 2;

[0038] The first branch support leg 4 is connected to the second branch support leg 6 through a branch connector 5. The upper end of the branch connector 5 is provided with a first branch support slot 501 for plugging the first branch support leg 4. The lower end of the branch connector 5 is provided with a second branch support slot 502 for plugging the second branch support leg 6. The second branch support leg 6 is provided with a plurality of legs;

[0039] It should be noted that in actual use, various forces such as pressure may cause the first slot 401 and the second supporting slot 502 to have different inclination angles.

[0040] The diameter of the first sub-support slot 501 is consistent with that of the first sub-support leg 4, ensuring that there is no gap between them and no relative movement occurs;

[0041] The diameter of the second sub-support slot 502 is consistent with that of the second sub-support leg 6, ensuring that there is no gap between them and no relative movement occurs;

[0042] The first supporting legs 4 are provided with three, and the second supporting legs 6 are provided with nine;

[0043] The main connector 2 and the branch connector 5 have the same structure. During actual production and on-site installation and use, only one type of support head needs to be produced, which saves the design and manufacturing costs of the production plant. During installation and use, the main connector 2 and the branch connector 5 have the same structure, so there is no need to select one, which speeds up the installation efficiency.

[0044] The main connector 2 and the branch connector 5 have the same structure.

[0045] The base 3 includes a plurality of bottom plates 7 , the number of the bottom plates 7 corresponds to the number of the sub-support legs, the bottom plates 7 are V-shaped, and each bottom plate 7 is provided with a base slot 701 for inserting the second sub-support leg 6 .

[0046] The inclination angle of the base slot 701 is consistent with the inclination angle of the second supporting leg 6 .

[0047] The base 3 also includes a connecting block, and two adjacent bottom plates 7 are detachably connected via the connecting block.

[0048] Both ends of the connecting block are folded upward to form a first C-shaped hook 8, a limiting connecting block 801 is provided in the middle position of the connecting block, and both ends of the bottom plate 7 are folded downward to form a second C-shaped hook corresponding to the first C-shaped hook 8, and the first C-shaped hook 8 is connected with the second C-shaped hook 802.

[0049] The bottom surface of the bottom plate 7 is also provided with supporting feet 9 .

[0050] Due to the different loads encountered during construction, here are two solutions for adjusting the overall height of the horse stool reinforcement:

[0051] Solution 1: When the plate is thin and the lateral load is small, the overall height can be adjusted by adjusting the height of the uppermost main support leg 1 of the saddle reinforcement or the height of the support foot 9.

[0052] Solution 2: When the slab is thicker, a good supporting effect cannot be achieved by adjusting the height of the uppermost main support leg 1 of the saddle bar or the height of the support foot 9. The reason is that when the lateral load on the saddle bar is large, if the height is adjusted by the method described in Solution 1, the overall stability will be reduced. When encountering a large lateral load (such as when pouring concrete), a large bending moment will be generated at the connection between the main support leg 1 and the upper steel bar, resulting in unreasonable force. Therefore, when the slab is thicker, the slab thickness problem can be solved by enlarging the overall proportion of the saddle bar. This can ensure the overall stability and withstand the large lateral load caused by pouring concrete.

[0053] Installation process:

[0054] Step 1: Determine the height of the tree-like structure horse stool reinforcement according to the thickness of the concrete slab and the thickness of the protective layer. The overall height and the size of each structure are determined by the general finite element software ANSYS form optimization.

[0055] Step 2: After the size of each component is determined, a mold is made in the factory and each component is poured out through the mold.

[0056] Step 3: prefabricate the tree-like structure horse stool reinforcement components in the factory. In order to facilitate the production, the diameters of the connecting rods are set to the same value. The connecting rods are uniformly made into an integrated long rod, and the long rod is cut according to different length requirements to obtain the second branch support leg 6 and the first branch support leg 4.

[0057] Step 4: dig out the middle solid parts of the branch connector 5 and the main connector 2 poured out of the mold to make a hollow sleeve for plugging the main supporting leg 1, the first branch supporting leg 4 and the second branch supporting leg 6.

[0058] Step 5. When making the base 3, it can be made into a long plate with a solid sleeve through a mold. The long plate includes a bottom plate 7 and a supporting foot 9. The solid sleeve is hollowed out to form a base slot 701, and then the bottom plate 12 is cut to form a second limit block 802 and a connecting block.

[0059] Step 6: Assemble the finished parts. During the assembly process, ensure that the parts are tightly connected and cannot slip out or fall off.

[0060] Step 7: Transport the fully assembled horse stool reinforcement to the construction site.

[0061] Step 8: Fix the main support leg 1 at the top of the horse stool reinforcement to a single steel bar on the upper steel mesh. Place the horse stool reinforcement on the lower steel mesh. Check whether the connection between the components is firm to prevent any component from falling off.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
