Description

Technical Field

[0001] The utility model relates to the technical field of concrete construction, in particular to an extra-long concrete construction structure. Background Art

[0002] An overlong concrete structure refers to a large concrete structure without expansion joints, which is formed in a certain direction of the building to meet special functional requirements or design aesthetics. Due to its overlong length, the temperature stress and shrinkage stress generated by the concrete during the hardening process may cause structural cracks, affecting the safety and durability of the building.

[0003] Therefore, some special measures need to be taken for the construction of such structures. The following measures are often used in construction: 1. Post-cast strip technology: reserve a post-cast strip of a certain width at the appropriate position of the structure, and pour it after the concrete on both sides reaches a certain age to release early temperature stress and shrinkage stress; 2. Skip-bin method: divide the super-long structure into several small sections and pour them in batches, leaving an interval between each batch to control temperature stress and shrinkage stress; 3. Use continuous expansion reinforcement strip: introduce a continuous concrete strip with expansion agent added at the appropriate position of the structure to make the concrete expand slightly during the hardening process to offset the shrinkage effect of other parts of the concrete and control the generation and development of cracks.

[0004] Among them, the continuous expansion reinforcement belt method is adopted. During construction, in order to ensure the effective separation of the expansion reinforcement belt and the surrounding concrete and avoid mutual interference of the expansion effect, a quick-closing net is usually installed at the joint of the two to isolate them. However, the installation of the quick-closing net is relatively inconvenient now, which can easily affect the construction efficiency. The quick-closing net is made up of multiple mesh pieces overlapped. After the overlap is completed, the mesh needs to be tied and fixed with the steel structure by binding wire, and finally supported by the on-site welded skeleton to keep it upright and fixed. In the actual construction site, due to the complex on-site construction environment and the messy placement of steel bars, the installation of the quick-closing net requires multiple tying and fixing. Therefore, when tying and fixing the mesh, the operating space is often limited, which is inconvenient to operate and easily affects the construction efficiency. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide an extra-long concrete construction structure to solve the problem that in the existing extra-long concrete construction process, the space for installing the quick-and-easy closing net is limited, thereby affecting the construction efficiency.

[0006] The technical solution adopted by the utility model is as follows:

[0007] An extra-long concrete construction structure comprises a top plate, a bottom plate, and a connecting rod detachably connected between the top plate and the bottom plate, a plurality of diagonal bracing rods are hinged on one side of the top plate along its length direction, the diagonal bracing rods are connected to a steel structure, an upper slide groove matching the upper side edge of a mesh is provided on the upper side of the top plate, a lower slide groove matching the lower side edge of the mesh is provided on the lower side of the bottom plate, the bottom plate is connected to the steel structure, the mesh slides horizontally between the upper slide groove and the lower slide groove, and limiting members for limiting the mesh from falling out are provided at both ends of the top plate.

[0008] Principle of the utility model:

[0009] When using this solution, the bottom plate, connecting rods, top plate and diagonal bracing rods can be pre-assembled to form a frame, and then the frame is placed in a predetermined position and connected to the steel structure, and then the mesh is horizontally slid between the upper slide and the lower slide. After all the meshes are loaded, the two ends of the top plate are locked by the limiter to prevent the outermost mesh from coming out. This solution adopts modular installation. After the frame is assembled, it is fixed to the corresponding position, and then the mesh is installed by sliding it into the upper and lower slides. This installation method not only solves the problem of limited installation due to the messy on-site construction environment, but also limits and guides the mesh by the upper and lower slides, so that the positioning and alignment of the mesh can be achieved. Compared with the traditional binding method, the operation of this solution is simpler, and the installation is more convenient and efficient. At the same time, the frame formed by the bottom plate, connecting rods and top plate can also be used as a reinforcing rib to improve the strength of the entire mesh, so that it can better resist the lateral pressure of concrete.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. This solution adopts modular installation, which not only solves the problem of limited installation due to the messy on-site construction environment, but also limits and guides the mesh through the upper and lower slide grooves, so as to achieve the positioning and alignment of the mesh, making the operation simpler and the installation more convenient, which is conducive to improving the construction efficiency.

[0012] 2. The frame composed of the bottom plate, connecting rods and top plate in this scheme can be used as reinforcement to improve the strength of the entire mesh plate so that it can better resist the lateral pressure of concrete.

[0013] As a preferred embodiment of the utility model, it also includes an intermediate plate located between the top plate and the bottom plate. The intermediate plate is detachably connected to the top plate and the bottom plate with connecting rods. A T-shaped groove is formed on one side of the intermediate plate. The spliced ​​sides of two vertically adjacent meshes are inserted into the T-shaped groove. In some concrete structures, the height of a single mesh may not be enough, and it is necessary to overlap the meshes vertically. The intermediate plate in this solution can be used to connect two vertically adjacent meshes. The intermediate plate is connected to the top plate and the bottom plate by a detachable connection method. It can be stacked according to the actual concrete height, and it is easy to disassemble and assemble.

This solution uses a split connection between the diagonal brace and the top plate, which can facilitate transportation and storage on the one hand, and on the other hand, can adjust the number of diagonal braces according to the actual strength of the concrete support, thereby adjusting the support strength and maximizing resource utilization.

[0015] As a preferred embodiment of the utility model, the connecting member includes a sleeve threadedly connected to the diagonal support rod, an arc plate is provided at one end of the sleeve away from the diagonal support rod, and locking bolts for locking the arc plate and the ear plate are passed through the arc plate and the ear plate. This solution uses a locking bolt to lock the arc plate and the ear plate, and the locking structure is simple and easy to operate.

[0016] As a preferred embodiment of the utility model, the upper side and the lower side of the mesh are both U-shaped folded edges. In this solution, the upper and lower sides of the mesh are set to be U-shaped. When the mesh is inserted into the upper and lower sliding grooves matched therewith, the horizontal part of the U-shaped folded edge can limit it vertically, and the vertical part of the U-shaped folded edge can limit it horizontally, so that the mesh is more stable.

[0017] As a preferred embodiment of the utility model, both side walls of the upper chute end are provided with through holes, the two through holes are coaxially arranged, and the limiting member includes a limiting rod penetrating the two through holes. In this solution, when the limiting rod is inserted into the two through holes, the limiting rod can limit the outermost mesh from coming out.

[0018] As a preferred embodiment of the utility model, it also includes a connecting sleeve arranged in cooperation with the mesh, the connecting sleeve is inserted into the overlapping area of ​​adjacent meshes, and the meshes and the connecting sleeve are spaced and slid into the upper slide groove and the lower slide groove. In this solution, the connecting sleeve is inserted into the overlapping area of ​​adjacent meshes, which can not only strengthen the connection between adjacent meshes, but also enhance the strength of the overlapping area of ​​the meshes, further improving the strength of the entire mesh panel.

[0025] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0026] In the description of the present application, the terms "top", "bottom", "one end", "one side", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present application.

[0027] See also Figure 1 and Figure 2 As shown, this embodiment discloses an extra-long concrete construction structure, including a top plate 2, a bottom plate 1 and a connecting rod 4 threadedly connected between the top plate 2 and the bottom plate 1. Specifically, a plurality of connecting tubes 41 are welded correspondingly along the length direction of the lower side of the top plate 2 and the upper side of the bottom plate 1, and an internal thread is provided in the connecting tube 41. Both ends of the connecting rod 4 are provided with external threads, which are connected by the matching of the internal and external threads.

[0028] A plurality of diagonal braces 5 are hingedly connected along one side of the top plate 2 in the length direction. Specifically, a plurality of ear plates 6 are evenly welded along one side of the top plate 2 in the length direction. A connector 7 is detachably connected to the upper end of the diagonal brace 5. The connector 7 includes a sleeve 71 threadedly connected to the diagonal brace 5. An arc plate 72 is welded to one end of the sleeve 71 away from the diagonal brace 5. Through holes are formed on the arc plate 72 and the ear plate 6. A locking bolt 61 is inserted into the through holes of the arc plate 72 and the ear plate 6. When in use, after the diagonal brace 5 is connected to the sleeve 71, the locking bolt 61 is inserted into the through holes of the arc plate 72 and the ear plate 6. Then, the angle of the diagonal brace 5 is adjusted. After the angle is adjusted, the nut 62 is screwed onto the locking bolt 61 until the arc plate 72 and the ear plate 6 are locked. The lower end of the diagonal brace 5 is welded and fixed to the steel structure. This solution uses the locking bolt 61 to lock the arc plate 72 and the ear plate 6. The locking structure is simple and easy to operate.

[0029] The upper side of the top plate 2 is provided with an upper slide groove that matches the upper side edge of the mesh 8, and the lower side of the bottom plate 1 is provided with a lower slide groove that matches the lower side edge of the mesh 8, and the mesh 8 can slide horizontally between the upper slide groove and the lower slide groove. Specifically, the upper side edge and the lower side edge of the mesh 8 are both U-shaped folded edges. Therefore, the upper slide groove and the lower slide groove are both U-shaped slide grooves, wherein the heights of the two side walls of the lower slide groove are inconsistent, and the lower end of the side wall with higher height extends outward to form an integral mounting plate 11, and the mounting plate 11 is welded to the steel structure. When installing the mesh 8, the mesh 8 slides in horizontally from the side, and then the horizontal part of the U-shaped slide groove can be used to vertically limit the mesh 8, and the vertical part of the U-shaped slide groove can be used to horizontally limit the mesh 8.

[0030] The top plate 2 is also provided with a stopper for limiting the mesh 8 from slipping out at both ends. Specifically, through holes are opened on both side walls of the upper chute end, and the two through holes are coaxially arranged. The stopper includes a stopper rod 21 inserted into the two through holes. In this solution, when the mesh 8 slides between the upper chute and the lower chute, the stopper rod 21 is inserted into the two through holes, and the stopper rod 21 can limit the outermost mesh 8 from slipping outward.

[0031] See also Figure 1 and Figure 4 As shown, the overlapping area of ​​adjacent meshes 8 is sleeved with a connecting sleeve 9, which is arranged in conjunction with the meshes 8. The upper side and the lower side of the connecting sleeve 9 are also U-shaped and can slide into the upper and lower slide grooves. When in use, the meshes 8 and the connecting sleeve 9 are spaced and slide between the upper slide groove and the lower slide groove, and the connecting sleeve 9 is sleeved in the overlapping area of ​​adjacent meshes 8. By setting the connecting sleeve 9, on the one hand, the connection of adjacent meshes 8 can be strengthened, and on the other hand, the strength of the overlapping area of ​​the meshes 8 can be enhanced, further improving the strength of the entire mesh board.

[0032] For further information, see Figure 3 As shown, in some concrete structures, the height of a single mesh sheet 8 may not be enough, and the mesh sheet 8 needs to be overlapped vertically. Therefore, this solution also includes an intermediate plate 3 that can be used to connect two vertically adjacent mesh sheets 8. Specifically, the intermediate plate 3 is located between the top plate 2 and the bottom plate 1. The upper and lower sides of the intermediate plate 3 are welded with a plurality of connecting tubes 41 along the length direction thereof. The intermediate plate 3 is respectively connected to the top plate 2 and the bottom plate 1 by connecting rods 4. One side of the intermediate plate 3 is provided with a T-shaped groove in cooperation with the U-shaped folding edge, and the side formed by the splicing of the two vertically adjacent mesh sheets 8 is inserted into the T-shaped groove. Among them, the number of intermediate plates 3 can be stacked according to the actual concrete height.

[0033] Specific implementation process:

[0034] When using this solution, the bottom plate 1, connecting rod 4, top plate 2 and diagonal brace rod 5 can be pre-assembled to form a frame, and then the frame is placed in a predetermined position and welded to the steel structure, and then the mesh 8 and connecting sleeves 9 are slid into the upper slide groove and the lower slide groove at intervals, and each connecting sleeve 9 is respectively inserted into the overlapping area of ​​an adjacent mesh 8. After all the meshes 8 and connecting sleeves 9 are installed, the limiting rods 21 are respectively inserted into the two ends of the upper slide groove to lock the two ends of the top plate 2 to prevent the outermost mesh 8 from escaping.

[0035] This solution adopts a modular installation. The frame is first assembled and then fixed to the corresponding position. Then the mesh 8 is installed by sliding it into the upper and lower slide grooves. This installation method can not only solve the problem of limited installation due to the messy on-site construction environment, but also limit the mesh 8 by the upper and lower slide grooves. The limiting and guiding of the mesh 8 can achieve the positioning and alignment of the mesh 8, making the operation simpler and the installation more convenient, which is conducive to improving the construction efficiency. At the same time, the frame structure formed by the bottom plate 1, the connecting rod 4, and the top plate 2 can be used as a reinforcing rib to improve the strength of the entire mesh plate, so that it can better resist the lateral pressure of the concrete, and it is highly practical.

[0036] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
