Description

Technical Field

[0001] This utility model belongs to the technical field of steel structure factory buildings, and in particular relates to a crack-proof structure for the foundation concrete of steel structure factory buildings. Background Technology

[0002] Steel structure workshops are one of the mainstream choices for modern industrial buildings. A steel structure workshop refers to a building whose main load-bearing components are made of steel, including steel columns, steel beams, steel foundations, steel roof trusses, and steel roofs. Its walls can also be enclosed with brick walls. Steel structure workshops have comprehensive advantages such as light weight, easy installation, short construction period, good seismic performance, and less environmental pollution. Compared with reinforced concrete structures, steel structure workshops have many advantages and are widely used in modern industrial buildings. However, to ensure their safety and stability, careful design, high-quality construction, strict acceptance, and regular maintenance are required. During the installation process of a steel structure workshop, concrete blocks need to be installed within it.

[0003] The existing authorized public account CN211850977U discloses a concrete crack-prevention structure, belonging to the field of building construction technology. It includes a waterproof layer, cooling water steel pipes, and a filter structure. The waterproof layer prevents rapid water loss from the concrete structure, thus preventing cracks. The filter structure prevents scale buildup inside the cooling water steel pipes, facilitating their long-term reuse. The filter structure includes a limiting hole, a limiting plate, and a filter plate. A fixing block on the filter plate, under the action of a compression spring, enters the limiting hole, causing the filter plate to abut against the limiting plate, enabling rapid installation. For removal, pressure is applied to the fixing block in the limiting hole until it completely detaches, allowing the filter plate to be removed, greatly improving installation and dismantling efficiency and simplifying operation. However, the aforementioned concrete crack-prevention structure involves placing S-shaped cooling water steel pipes inside the concrete structure. This installation can damage the internal structure of the concrete, affecting its overall strength. Therefore, it is necessary to provide a concrete crack-prevention structure for steel structure factory foundations to address these issues. Utility Model Content

[0004] The technical content of this utility model is to provide a crack-resistant concrete foundation structure for steel structure factory buildings.

[0005] To address the aforementioned problems, this utility model provides a concrete anti-crack structure for steel structure factory foundations, comprising a steel frame, an open inner side of the steel frame, a sealing plate mounted on the top of the steel frame via locking bolts, buffer blocks mounted on the inner side of the steel frame and the bottom of the sealing plate, a concrete block mounted on the inner side of the steel frame, buffer springs mounted on the bottom of the sealing plate and the inner side of the steel frame, a fixing plate mounted on the bottom of the steel frame, a guide tube mounted on the fixing plate, a fixing rod mounted inside the guide tube, a fixing block mounted on the top of the fixing rod, an L-plate mounted on the fixing plate, and a reinforcing block mounted on the L-plate.

[0006] As a further solution of this utility model, the steel frame is configured as a rectangular structure, the top of the steel frame is configured as an open structure, the thickness of the concrete block is the same as the inner depth of the steel frame, the inner dimension of the steel frame is larger than the size of the concrete block installed therein, two sets of fixing bolts are symmetrically installed on the sealing plate, and fixing holes are opened on both sides of the top of the steel frame, so that the sealing plate is fixedly installed on the top of the steel frame by fixing bolts.

[0007] As a further solution of this utility model, a set of buffer springs is installed on both sides of the inner bottom of the steel frame. The buffer springs are configured as an inclined structure. The bottom sides of the concrete block are in contact with the tops of the two sets of buffer springs installed on the inner bottom of the steel frame. There is a certain gap between the bottom of the concrete block and the inner bottom of the steel frame, so that the bottom of the concrete block has a certain expansion space.

[0008] As a further solution of this utility model, a set of buffer blocks is installed on the inner sides and bottom of the steel frame. The size of the buffer blocks is smaller than the inner dimensions of the steel frame, and the thickness of the buffer blocks is the same as the inner depth of the steel frame. The three sets of buffer blocks are in contact with the sides and bottom of the concrete block, thereby assisting the buffer spring in providing support for the concrete block.

[0009] As a further solution of this utility model, two sets of buffer springs are symmetrically installed at the bottom of the sealing plate. The buffer springs are configured as an inclined structure. The top two sides of the concrete block are in contact with the bottom of the two sets of buffer springs installed at the bottom of the sealing plate. At the same time, the bottom of the buffer block installed at the bottom of the sealing plate is in contact with the top of the concrete block, thereby giving the top of the concrete block an expansion space.

[0010] As a further solution of this utility model, the width of the fixing plate is greater than the width of the steel frame, the length of the fixing plate is the same as the length of the steel frame, guide tubes are installed at the four corners of the fixing plate, the inner diameter of the guide tubes is the same as the diameter of the fixing rod, and the bottom of the fixing rod is set as a tapered structure so as to fix the fixing rod in the fixing hole opened in the ground.

[0011] As a further solution of this utility model, L-plates are installed on both sides of the bottom of the steel frame. The sides of the L-plates are fixedly connected to the bottom sides of the steel frame, and the bottom of the L-plates is fixedly connected to the top of the fixing plate. Multiple sets of reinforcing blocks are installed on the L-plates. The reinforcing blocks are perpendicular to the L-plates, which can increase the strength of the L-plates themselves.

[0012] Compared with related technologies, the anti-crack structure for concrete foundation of steel structure factory buildings provided by this utility model has the following beneficial effects:

[0013] 1. This utility model has a set of buffer springs installed on both sides of the bottom inner side of the steel frame. The buffer springs are set with an inclined structure, and the top of the steel frame is set with an open structure. When the concrete block is installed on the steel frame from top to bottom, the bottom sides of the concrete block contact the top of the two sets of buffer springs, thereby providing support for the concrete block through the two sets of buffer springs. At the same time, a set of buffer blocks are installed on both sides and the bottom of the inner side of the steel frame. The three sets of buffer blocks contact the sides and bottom of the concrete block. The buffer springs and buffer blocks can be compressed, so that the concrete block has expansion space on all sides, which can effectively prevent the concrete from cracking. Compared with the comparative case, this device does not affect the strength of the concrete block itself.

[0014] 2. This utility model installs guide tubes at the four corners of the fixed plate, and a fixed rod is installed in the guide tube. The inner diameter of the guide tube is the same as the diameter of the fixed rod. The bottom of the fixed rod is set as a conical structure. By using a tool to hammer the fixed block installed on the top of the fixed rod, the fixed rod can be moved downward along the guide tube, thereby fixing the fixed rod in the fixed hole opened in the ground, thus realizing the overall fixed installation of the device.

[0015] 3. This utility model increases the connection strength between the steel frame and the fixed plate by installing L-plates on both sides of the bottom of the steel frame. The sides of the L-plates are fixedly connected to the bottom sides of the steel frame, and the bottom of the L-plates is fixedly connected to the top of the fixed plate. Multiple sets of reinforcing blocks are installed on the L-plates, which are perpendicular to the L-plates and can increase the strength of the L-plates themselves. Attached Figure Description

[0024] Please refer to the following: Figure 1-6 A crack-resistant concrete foundation structure for a steel structure factory building includes a steel frame 1. The inner side of the steel frame 1 is set as an open structure. A sealing plate 3 is installed on the top of the steel frame 1 through locking bolts 2. Buffer blocks 4 are installed on the inner side of the steel frame 1 and the bottom of the sealing plate 3. Concrete blocks 5 are installed on the inner side of the steel frame 1. Buffer springs 6 are installed on the bottom of the sealing plate 3 and the inner side of the steel frame 1. A fixing plate 7 is installed at the bottom of the steel frame 1. A guide tube 8 is installed on the fixing plate 7. A fixing rod 9 is installed inside the guide tube 8. A fixing block 10 is installed on the top of the fixing rod 9. An L-plate 11 is installed on the fixing plate 7. A reinforcing block 12 is installed on the L-plate 11.

[0025] Preferably, the steel frame 1 is configured as a rectangular structure, and the top of the steel frame 1 is configured as an open structure so that the concrete block 5 can be installed from the top of the steel frame 1 into the interior of the steel frame 1. The thickness of the concrete block 5 is the same as the inner depth of the steel frame 1, and the inner dimension of the steel frame 1 is larger than the size of the concrete block 5 installed therein, so that the concrete block 5 has a certain expansion space. Two sets of fixing bolts are symmetrically installed on the sealing plate 3, and fixing holes are opened on both sides of the top of the steel frame 1, so that the sealing plate 3 is fixedly installed on the top of the steel frame 1 by fixing bolts, thereby closing the steel frame 1 and preventing the concrete block 5 installed therein from detaching from the steel frame 1.

[0026] Preferably, a set of buffer springs 6 are installed on both sides of the inner bottom of the steel frame 1. The buffer springs 6 are set in an inclined structure. When the concrete block 5 is installed on the steel frame 1 from top to bottom, the bottom sides of the concrete block 5 contact the top of the two sets of buffer springs 6 installed on the inner bottom of the steel frame 1. Thus, the two sets of buffer springs 6 provide support for the concrete block 5, so that there is a certain gap between the bottom of the concrete block 5 and the inner bottom of the steel frame 1, thereby giving the bottom of the concrete block 5 a certain expansion space.

[0027] Preferably, a set of buffer blocks 4 are installed on both sides and the bottom of the inner side of the steel frame 1. The size of the buffer blocks 4 is smaller than the inner side size of the steel frame 1, and the thickness of the buffer blocks 4 is the same as the inner depth of the steel frame 1. The three sets of buffer blocks 4 are in contact with the sides and bottom of the concrete block 5, thereby assisting the buffer spring 6 in providing support for the concrete block 5. When the concrete block 5 is heated and expands, the buffer blocks 4 are compressed accordingly, thereby continuously providing support for the concrete block 5, and thus installing the concrete block 5 more stably on the inner side of the steel frame 1.

[0028] Preferably, two sets of buffer springs 6 are symmetrically installed at the bottom of the sealing plate 3. The buffer springs 6 are set in an oblique structure. When the sealing plate 3 is fixedly installed to the steel frame 1, the top two sides of the concrete block 5 are in contact with the bottom of the two sets of buffer springs 6 installed at the bottom of the sealing plate 3. At the same time, the bottom of the buffer block 4 installed at the bottom of the sealing plate 3 is in contact with the top of the concrete block 5, so that the top of the concrete block 5 has an expansion space. By reserving an expansion space around the concrete block 5, the cracking of the concrete can be effectively prevented.

[0029] Preferably, the width of the fixing plate 7 is greater than the width of the steel frame 1, the length of the fixing plate 7 is the same as the length of the steel frame 1, and guide tubes 8 are installed at the four corners of the fixing plate 7. The inner diameter of the guide tubes 8 is the same as the diameter of the fixing rod 9. The bottom of the fixing rod 9 is set as a conical structure. By using a tool to hammer the fixing block 10, the fixing rod 9 can be moved downward along the guide tube 8, so that the fixing rod 9 can be fixedly installed in the fixing hole opened in the ground. Thus, the overall fixing installation of the device is achieved by the four sets of fixing rods 9.

[0030] Preferably, L-plates 11 are installed on both sides of the bottom of the steel frame 1. The sides of the L-plates 11 are fixedly connected to the bottom sides of the steel frame 1, and the bottom of the L-plates 11 is fixedly connected to the top of the fixing plate 7. Thus, the connection between the steel frame 1 and the fixing plate 7 is strengthened by the L-plates 11. Multiple sets of reinforcing blocks 12 are installed on the L-plates 11. The reinforcing blocks 12 are perpendicular to the L-plates 11, which can increase the strength of the L-plates 11 themselves.
