Description

Technical Field

[0001] This application relates to the field of underground building construction structures, and more particularly to a construction structure for a basement and its construction method. Background Technology

[0002] A basement is a building structure built below the ground floor of a building. In the field of modern construction, building basements as parking lots or shops can increase the usable area of ​​a building.

[0003] Current basement construction work requires workers to first excavate a foundation pit, then lay a level concrete floor in the pit, and finally pour walls and cap the pit. The capped area can withstand a large load and can serve as a road for construction vehicles. Through this step-by-step construction, the construction of a large basement area can eventually be completed.

[0004] The aforementioned technical solutions have the following drawbacks: during the excavation of the foundation pit, construction personnel and transport vehicles need to enter the pit for construction, and there is a risk of the foundation pit collapsing during the construction process, making the construction dangerous. Summary of the Invention

[0005] To improve the safety of basement construction, this application provides a basement construction structure and construction method thereof.

[0006] The technical solution for the construction structure of a basement provided in this application is as follows:

[0007] A construction structure for a basement includes a support structure and a casting formwork. The support structure includes multiple right-angled plates and multiple flat plates, with the flat plates positioned between adjacent right-angled plates. The multiple right-angled plates and the multiple flat plates form a frame structure. The support structure is installed in the foundation pit and abuts against the inner wall of the foundation pit. The right-angled plates and flat plates are detachably connected. The casting formwork is positioned outside the support structure, and there is a gap between the casting formwork and the support structure for injecting cement mortar.

[0008] By adopting the above technical solution, a support structure is set up inside the foundation pit, forming a square tube structure that abuts against the side wall of the foundation pit, thereby achieving the effect of retaining soil. After the support structure is installed, construction workers can enter the foundation pit to transport soil and pour the floor. By setting up a pouring formwork outside the support structure, a gap is created between the pouring formwork and the support structure. Cement mortar is poured between the pouring formwork and the support structure, allowing the cement mortar to solidify and form a concrete wall. At this point, construction workers can remove the support structure and the pouring formwork, allowing the concrete wall to be used for retaining soil, thus improving the safety of construction.

[0009] Optionally, the right-angle plate is provided with multiple ribs, which are spaced apart along the vertical direction.

[0010] By adopting the above technical solution, ribs are set on the right-angle plate to support both sides of the right-angle plate, thereby reducing the probability of deformation of the support structure in the foundation pit.

[0011] Optionally, the right-angle plate is provided with multiple hangers, and the plate is provided with multiple structural beams. The structural beams are fixed to one side surface of the plate, and the ends of the structural beams are used to be snapped onto the hangers.

[0012] By adopting the above technical solution, hangers are installed on the right-angle plates, and multiple structural beams are fixed on the flat plate. The structural beams are fixed between the two right-angle plates by snap-fit. Construction workers can move the flat plate with a crane, so that the flat plate is connected to the right-angle plates, which facilitates the loading and unloading of the support structure. The ends of the structural beams are snap-fitted with the hangers, which serves to support the flat plate.

[0013] Optionally, the support structure may have an inlet / outlet on the side closest to the ground.

[0014] By adopting the above technical solution, and by opening an entrance and exit on one side of the support structure, transport vehicles can enter the foundation pit and transport earth.

[0015] Optionally, multiple scaffolds are provided on the inner wall of the support structure away from the entrance and exit, and the scaffolds are spaced apart in the vertical direction.

[0016] By adopting the above technical solution and setting up scaffolding inside the support structure, when the foundation pit collapses, the excavated soil can easily enter the support structure from the inlet and outlet, and the construction workers can leave the foundation pit through the scaffolding, thereby improving construction safety.

[0017] Optionally, the casting template includes two limiting plates and three side plates. The three side plates are connected to each other to form a semi-frame structure. The limiting plates are installed on the side plates, and a gap is formed between the two limiting plates. The limiting plates are connected to the support structure, and a gap is formed between the support structure and the casting template.

[0018] By adopting the above technical solution, a limiting plate is set on the side plate to connect the limiting plate with the support structure, thereby forming a cavity between the support structure and the pouring template. After the cement mortar solidifies, the support structure can move horizontally and be moved out from one side of the concrete wall, which facilitates the construction personnel to hoist the support structure.

[0019] Optionally, the support structure is provided with fixing clips, which include multiple horizontal bars and multiple vertical bars. The horizontal bars and vertical bars are perpendicular to each other and are set outside the support structure. The fixing clips are used to abut against the support structure, and the ends of the fixing clips are used to fix them to the ground.

[0020] By adopting the above technical solution, and by setting fixing clips on the support structure, the horizontal and vertical bars supporting the support structure are exposed on the side outside the pit, thereby enabling the support structure to maintain structural stability and reducing the probability of deformation of the support structure inside the pit.

[0021] The construction method for a basement structure provided in this application adopts the following technical solution:

[0022] A construction method for a basement structure includes the following steps:

[0023] S1: Excavate the foundation pit and install a support structure inside the pit;

[0024] S2: Transport the excavated soil from the foundation pit and carry out the concrete paving work at the bottom of the foundation pit;

[0025] S3: Replace the flat plate and hoist the right-angle plate to reduce the footprint of the support structure;

[0026] S4: Set up a casting template on the support structure, pour cement mortar between the support structure and the casting template, and carry out excavation work on one side of the foundation pit.

[0027] S5: After the cement mortar has solidified, move the support structure to the unconstructed foundation pit area and remove the pouring formwork by hoisting.

[0028] By adopting the above technical solution, the support structure is hoisted into the foundation pit, and the support structure is assembled and supports the inner wall of the foundation pit. The support structure can protect the construction site. After the construction in the foundation pit is completed, the construction workers can use a crane to remove the flat plate and move the right angle plate, which can reduce the footprint of the support structure and create a gap between the support structure and the foundation pit. The construction workers can then easily pour cement mortar between the pouring formwork and the support structure by installing the pouring formwork in the foundation pit and connecting it with the support structure.

[0029] In summary, the beneficial technical effects of this application are as follows:

[0030] 1. By setting a flat plate between right-angle plates, the right-angle plates and the flat plate are connected by structural beams, so that the support structure can play the role of retaining soil in the foundation pit, reducing the risk of foundation pit collapse and improving the safety of construction workers in the foundation pit.

[0031] 2. By setting up a casting template outside the support structure, the support structure can act as a cement template, which makes it easier for construction workers to pour concrete walls in the foundation pit. After the concrete walls are formed, construction workers can use a crane to move the support structure horizontally, so that the support structure can be moved away from one side of the concrete wall, which makes it easier to move the support structure.

[0032] 3. By installing fixing clips on the support structure, the ends of the fixing clips can be fixed to the ground, thereby providing support to the support structure and reducing the probability of displacement of the support structure in the foundation pit. Attached Figure Description

[0039] The present application will be further described in detail below with reference to the accompanying drawings.

[0040] This application discloses a construction structure and construction method for a basement, referring to... Figure 1 , Figure 2 and Figure 3The structure includes a support structure 1, a pouring formwork 2, and fixing clips 3. The support structure 1 is installed inside the foundation pit 4. A slope 5 is provided on one side of the foundation pit 4. The foundation pit 4 is a rectangular deep pit. The slope 5 formed by the excavation on one side of the foundation pit 4 allows transport vehicles to enter the bottom of the foundation pit 4 via the slope 5, thereby achieving the effect of transporting excavated soil. The support structure 1 is installed in the foundation pit 4 and abuts against the inner wall of the foundation pit 4, thereby improving construction safety and reducing the probability of the inner wall of the foundation pit 4 collapsing. After the excavation of the foundation pit 4 is completed, the construction workers reset the support structure 1 to create a gap between the support structure 1 and the inner wall of the foundation pit 4. By placing the pouring formwork 2 on the support structure 1, a cavity structure is formed by the support structure 1, the pouring formwork 2, and the inner wall of the foundation pit 4. The construction workers pour cement mortar into the cavity, which solidifies to form a concrete structure, thereby further improving the structural strength inside the foundation pit 4. The fixing clip 3 is detachably connected to the support structure 1. The fixing clip 3 is used to keep the support structure 1 vertical, thereby improving the pouring quality when pouring cement mortar.

[0041] Reference Figure 4 and Figure 5 The support structure 1 includes multiple right-angled plates 11 and multiple flat plates 12. In this embodiment, four right-angled plates 11 and four flat plates 12 are used. Each right-angled plate 11 is a plate with a right-angled cross-section. Each side of the right-angled plate 11 is connected to a flat plate 12. The multiple right-angled plates 11 and multiple flat plates 12 can form a rectangular frame structure. By placing the support structure 1 inside the foundation pit 4, the construction workers can make the support structure 1 abut against the vertical inner wall of the foundation pit 4, thereby supporting the inner wall of the foundation pit 4 and achieving the purpose of retaining soil.

[0042] Reference Figure 4 and Figure 5 The right-angle plate 11 has multiple ribs 111 fixed to two mutually perpendicular plates. The ribs 111 are spaced apart along the length of the right-angle plate 11, enhancing its structural strength. Multiple hangers 112 are mounted on the right-angle plate 11, and multiple structural beams 121 are mounted on the flat plate 12. The structural beams 121 are bolted to the flat plate 12 and are horizontally positioned on the flat plate 12, spaced apart vertically. Each end of a structural beam 121 engages with a hanger 112 on one of the right-angle plates 11, thus connecting the flat plate 12 and the right-angle plate 11. When the surfaces of the flat plate 12 and the right-angle plate 11 are subjected to earth pressure, the structural beams 121 and hangers 112 bear stress, thus providing a retaining effect.

[0043] Reference Figure 3 and Figure 4An entrance / exit 13 is provided on the side of the support structure 1 closest to the slope 5, and the entrance / exit 13 is located on a flat plate 12. After the support structure 1 is installed in the foundation pit 4, transport vehicles can enter and exit the foundation pit 4 through the entrance / exit 13. Multiple scaffolding 122s are installed on the inner wall of the support structure 1, spaced apart vertically, and located on the inner wall of the support structure 1 away from the entrance / exit 13. When the foundation pit 4 collapses, there is a chance that soil will enter the support structure 1 through the entrance / exit 13. Construction workers in the foundation pit 4 can leave the foundation pit 4 through the scaffolding 122 on the side away from the entrance / exit 13, thereby improving construction safety.

[0044] Reference Figure 2 and Figure 4 The casting template 2 is installed on the support structure 1. The casting template 2 is a plate structure, and the casting template 2 and the support structure 1 are fixedly connected by bolts. In other embodiments, the casting template 2 is set as a frame structure, including two limiting plates 21 and three side plates 22. The three side plates 22 are connected to each other to form a semi-frame structure. The two limiting plates 21 are respectively set on both sides of the frame. The support structure 1 is set in the casting template 2 and can slide through the gap between the two limiting plates 21. When the casting template 2 is installed outside the support structure 1, the construction workers can pour cement mortar between the support structure 1 and the casting template 2. By setting bolts at the ends of the structural beam 121, the construction workers can make the right-angle plate 11 and the flat plate 12 tightly connected, thereby improving the sealing of the surface of the support structure 1. After the cement mortar solidifies, the construction workers can detach the casting template 2 from the support structure 1, and then the support structure 1 and the casting template 2 can be removed from the foundation pit 4 by hoisting.

[0045] Reference Figure 4 Multiple flat plates 12 are provided, and the widths of the multiple flat plates 12 are different. After the construction workers install the support structure 1 in the foundation pit 4 and complete the excavation of the foundation pit 4, they can lift and move the right angle plate 11 by unloading the multiple flat plates 12 from the right angle plate 11. By setting smaller flat plates 12 between the right angle plates 11, the area occupied by the support structure 1 can be reduced, and a gap can be formed between the support structure 1 and the foundation pit 4. At this time, the construction workers can lift the pouring formwork 2 into the foundation pit 4 and connect the pouring formwork 2 to the support structure 1 from the outside.

[0046] Reference Figure 3 The casting template 2 is equipped with a clamping plate 23, which is installed on the limiting plate 21 of the casting template 2. One end of the clamping plate 23 is connected to a limiting plate 21. When the construction personnel hoist the right angle plate 11, they can use the crane to abut the right angle plate 11 against the clamping plate 23, thereby facilitating the placement of the right angle plate 11.

[0047] Reference Figure 3The fixing clip 3 includes two horizontal bars 31 and two vertical bars 32. The horizontal bars 31 and vertical bars 32 are perpendicular to each other. The horizontal bars 31 and vertical bars 32 are respectively set on the outside of the support structure 1 and abut against the support structure 1. The ends of the horizontal bars 31 or vertical bars 32 can be fixed to the ground by bolts, so that the fixing clip 3 can support the support structure 1 and reduce the probability of the support structure 1 shifting in the pit 4.

[0048] The implementation principle of this application embodiment is as follows: By setting a support structure 1 in the foundation pit 4, the support structure 1 supports the inner wall of the foundation pit 4, thereby improving construction safety. By detachably connecting the flat plate 12 between the right angle plates 11, the construction personnel can move the right angle plates 11 and set the flat plate 12 between the right angle plates 11, thereby reducing the footprint of the support structure 1 and forming a cavity between the support structure 1 and the foundation pit 4. By setting the pouring template 2 on the support structure 1, the construction personnel can put cement mortar between the support structure 1 and the pouring template 2, so that the cement mortar can solidify to form a wall, thereby completing the construction of the basement wall. After the construction is completed, the construction personnel can move the support structure 1 and the pouring template 2 to carry out the construction of the next area.

[0049] This embodiment discloses a construction method for an underground construction structure, including the following steps:

[0050] S1: Excavate foundation pit 4 and install support structure 1 inside foundation pit 4;

[0051] S2: Transport the excavated soil in the foundation pit 4 and carry out the concrete paving work at the bottom of the foundation pit 4;

[0052] S3: Replace the flat plate 12 and hoist the right-angle plate 11 to reduce the floor area of ​​the support structure 1;

[0053] S4: Set up a casting template 2 on the support structure 1, pour cement mortar between the support structure 1 and the casting template 2, and carry out excavation work on one side of the foundation pit 4.

[0054] S5: After the cement mortar has solidified, move the support structure 1 to the unconstructed foundation pit area and remove the pouring formwork 2 by hoisting.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
