[0002] The foundations of large steel structure factory buildings require the installation of pile caps, foundation slabs, and ground beams. Currently, foundation excavation typically involves large-scale simultaneous excavation, followed by the pouring of pile caps in the excavated soil. After the pile caps are formed, foundation slabs are poured on top of them. The ground beam is usually located in the middle of the side wall of the foundation slab, therefore backfilling is necessary after the foundation slab is formed before the ground beam can be poured. In this construction method, after the foundation slab is cast, the backfilling must be completed before the ground beam can be poured, which not only increases labor costs but also extends the construction period, hindering project cost control.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] Example:

[0036] like Figures 1-7 As shown, this embodiment provides an integral casting mold for the cup opening and ground beam on a foundation platform, which is used to cast the cup opening and ground beam on the foundation platform in one step. The mold includes a cup opening forming mold 200 and a ground beam forming mold 300, wherein:

[0037] A cup-shaped forming mold 200 is mounted on a support platform 100. The cup-shaped forming mold 200 has a first cavity, within which a cup-shaped steel reinforcement frame 700, formed by binding, is installed. The cup-shaped steel reinforcement frame 700 is connected to the support platform 100. The function of the cup-shaped steel reinforcement frame 700 is to improve the structural strength of the cup rim, enhance its ductility, and constrain the deformation after the cup rim is formed.

[0038] The ground beam forming mold 300 is erected on the foundation ground via a support structure. The ground beam forming mold 300 has a second cavity, and its end is connected to the cup-shaped forming mold 200. The second cavity is connected to the first cavity. A long, strip-shaped steel reinforcement frame 800, formed by binding, is provided in the second cavity and connected to the cup-shaped steel reinforcement frame 700. The function of the aforementioned ground beam steel reinforcement frame is to improve the structural strength of the ground beam, enhance its ductility, and constrain the deformation after cup-shaped forming.

[0039] It should be noted that the cup-shaped steel bar frame 700 and the long strip steel bar frame 800 mentioned above are both existing technologies. Both are made by binding steel bars together. The outer contour of the cup-shaped steel bar frame 700 is shaped like a cup with a bottom, while the outer contour of the long strip steel bar frame 800 is shaped like a cuboid.

[0040] With the above structure, when pouring the cup on the foundation 100, the concrete is poured into the cup forming mold 200 and then flows into the ground beam forming mold 300. The ground beam forming mold 300 is supported on the ground surface by the support part, so that the cup and ground beam on the foundation 100 are poured and formed at one time. After the cup and ground beam are formed, the soil is backfilled, thereby reducing labor costs and shortening the construction period of the foundation 100, the cup and ground beam.

[0041] Optionally, the aforementioned support component is a scaffold 400 made of steel pipes, which has a simple structure, is easy to manufacture, and is easy to assemble and disassemble, resulting in low cost. Of course, the aforementioned support component can also be a mechanical jack.

[0042] An optional implementation of this embodiment is as follows: The cup-mouth forming mold 200 includes an inner mold 210 and an outer mold 220, wherein:

[0043] The inner mold 210 is prefabricated in the factory and is shaped like a rectangular column. It is transported to the construction site as a whole by a transport vehicle. The inner mold 210 is inserted into the cup-shaped steel reinforcement frame 700 and overlaps the bottom of the cup-shaped steel reinforcement frame 700. To ensure sufficient structural strength, several support strips are prefabricated inside the inner mold 210. The outer mold 220 is erected on the foundation 100. The outer mold 220 is a square tube structure assembled from multiple plates and covers the cup-shaped steel reinforcement frame 700. A first cavity is formed between the inner mold 210 and the outer mold 220. It is easy to understand that the top of the first cavity is penetrating through it. During construction, concrete is injected into the first cavity through the top penetrating opening.

[0044] Furthermore, multiple first clamping components 500 are installed outside the cup-shaped mold 200. The multiple first clamping components 500 are used to hold the cup-shaped mold 200 tightly. Specifically, the multiple first clamping components 500 act on the outside of the outer mold 220 to prevent the concrete from expanding the outer mold 220 when pouring concrete.

[0045] To prevent pressure release from the first cavity of the cup-shaped mold 200 during concrete pouring, in this embodiment, the bottom end of the inner mold 210 overlaps the bottom of the cup-shaped steel reinforcement frame 700, and a sealing plate 211 is provided at the bottom of the inner mold 210, with an exhaust hole 212 on the sealing plate 211. During concrete pouring, the exhaust hole 212 helps to expel gas from the first cavity, preventing displacement of the inner mold 210 or outer mold 220 due to excessive pressure during concrete pouring. Furthermore, the exhaust hole 212 also helps to reduce temperature.

[0046] To facilitate the removal of the inner mold 210 after the cup rim is formed, in this embodiment, pearl cotton 213 is also placed between the inner mold 210 and the cup-shaped steel reinforcement frame 700. In fact, the pearl cotton 213 is attached to the outer wall of the inner mold 210. This ensures that the inner mold 210 can be easily detached from the inner wall of the cup rim after it is formed, thus facilitating the recycling and reuse of the inner mold 210.

[0047] Optionally, the first clamping assembly 500 includes four horizontal steel pipes 520 and a first tie bolt 530. Several vertical steel pipes 510 are evenly distributed on the support platform 100 outside the outer mold 220 of the cup forming mold. The four horizontal steel pipes 520 are arranged in pairs to form two groups of steel pipes. The two groups of steel pipes are respectively placed on both sides of the vertical steel pipes 510, and the two groups of steel pipes are pressed against the outer wall of the vertical steel pipes 510 by the first tie bolts 530, so as to press the vertical steel pipes 510 against the outside of the cup forming mold 200.

[0048] The aforementioned tie bolts are commonly used fasteners in the construction industry. They include a threaded rod, two nuts, and two pressure blocks. In use, the threaded rod is inserted between the two horizontal steel pipes 520 of the steel pipe assembly, with both ends of the threaded rod extending beyond the two sets of steel pipes. The pressure blocks are then slidably inserted onto the threaded rod, with the two pressure blocks positioned on either side of the two sets of steel pipes. The nuts are then screwed onto the threaded rod, with the two nuts positioned on either side of the two pressure blocks. Using the preload of the nuts on the threaded rod, when both nuts are tightened simultaneously, the pressure blocks press against the two horizontal steel pipes 520 in the steel pipe assembly. It is worth noting that a first fastening assembly 500 actually includes two first tie bolts 530, which are located on either side of the cup-shaped mold 200.

[0049] Part of the horizontal steel pipe 520 of the first clamping assembly 500 extends laterally, and this part of the first clamping assembly 500 can clamp the cup-shaped mold 200 longitudinally. Another part of the horizontal steel pipe 520 of the first clamping assembly 500 extends vertically, and this part of the first clamping assembly 500 can clamp the cup-shaped mold 200 laterally. The arrangement of the vertical steel pipe 510 allows the clamping force applied by the first clamping assembly 500 to the cup-shaped mold 200 to be applied more evenly to the cup-shaped mold 200.

[0050] Of course, the first clamping component 500 mentioned above can also be tightened step by step. In this case, it is not necessary to arrange the vertical steel pipe 510 outside the cup forming mold 200.

[0051] An optional implementation of this embodiment is as follows: The above-mentioned ground beam forming mold 300 includes a base plate 310 and two side plates 320, wherein:

[0052] A base plate 310 is placed on a support, and a long strip of steel reinforcement 800 is located above the base plate 310. Two side plates 320 overlap the base plate 310, with the two side plates 320 located on either side of the long strip of steel reinforcement 800. A second cavity exists between the base plate 310 and the two side plates 320, with the top and both ends of the second cavity penetrating through it. A through hole 221 is provided in the outer mold 220, through which the long strip of steel reinforcement 800 passes. The ends of the base plate 310 and the two side plates 320 are inserted into the through hole 221, so that the ground beam forming mold 300 is connected to the cup-shaped forming mold 200. Thus, the end opening of the ground beam forming mold 300 is connected to the first cavity of the cup-shaped forming mold 200, thereby connecting the first cavity and the second cavity.

[0053] It should be noted that, under normal circumstances, the ground beam is set between the cup openings on the two foundations 100. Therefore, the two ends of the cedar ground beam forming mold 300 are respectively connected to the two cup opening forming molds 200.

[0054] Optionally, multiple second clamping assemblies 600 are also installed outside the aforementioned ground beam forming mold 300. These second clamping assemblies 600 are used to hold the ground beam forming mold 300 tightly to prevent the side plate 320 from expanding during concrete pouring. Specifically, each second clamping assembly 600 includes four vertical timber beams 610 and two tie bolts 620. The four vertical timber beams 610 are arranged in pairs to form two timber beam groups. The two timber beam groups are placed on both sides of the ground beam forming mold 300, and are pressed tightly against the outside of the ground beam forming mold 300 by the second tie bolts 620.

[0055] In practical use, the threaded rod of the tie bolt is threaded between the two vertical timbers 610 of the timber assembly, with both ends of the threaded rod extending out of the two timber assemblies respectively. Then, the clamping blocks of the tie bolt are slidably threaded onto the threaded rod, with the two clamping blocks positioned on either side of the two timber assemblies. Next, the nuts of the tie bolt are screwed onto the threaded rod, with the two nuts positioned on either side of the two clamping blocks. Using the preload of the nuts on the threaded rod, when both nuts are tightened simultaneously, the clamping blocks press against the two vertical timbers 610 in the timber assembly, thereby clamping the side plate 320 of the ground beam forming mold 300 using the two sets of vertical timbers 610. It is worth noting that a set of second clamping components 600 actually includes two second tie bolts 620, located above and below the ground beam forming mold 300 respectively.

[0056] Multiple sets of the aforementioned second clamping components 600 are sequentially arranged along the length direction of the ground beam forming mold 300, thereby applying a uniform clamping force along the length direction of the ground beam forming mold 300.

[0057] Of course, the second clamping component 600 mentioned above can also be a step-by-step clamping mechanism.

[0058] The construction and usage methods of the mold provided in this embodiment are as follows:

[0059] Step 1: According to the drawings and construction requirements, pour a 100mm foundation on the foundation ground;

[0060] Step 2: Tie the aforementioned cup-shaped steel reinforcement frame 700 onto the foundation 100;

[0062] Step 4: Securely install the base plate 310 of the ground beam forming mold 300 onto the scaffolding 400;

[0063] Step 5: Tie the above-mentioned long strip steel bar frame 800, and connect the end of the long strip steel bar frame 800 with the above-mentioned fastened steel bar frame.

[0064] Step 6: Insert the inner mold 210 of the cup mouth forming mold 200 into the cup-shaped steel bar frame 700;

[0065] Step 7: Install an outer mold 220 on the outside of the cup-shaped steel bar frame 700, and make the outer mold 220 form the above-mentioned through hole 221. Place the long strip steel bar frame 800 in the above-mentioned through hole 221, and insert the end of the above-mentioned bottom plate 310 into the above-mentioned through hole 221, so that the bottom plate 310 is overlapped by the hole edge of the through hole 221.

[0066] Step 8: Install the two side plates 320 of the ground beam forming mold 300 so that the ends of the side plates 320 enter the through holes 221.

[0067] Step 9: Install the first clamping assembly 500 on the outside of the formed cup-mouth forming mold 200, and install the second clamping assembly 600 on the outside of the formed ground beam forming mold 300;

[0068] Step 10: Pour concrete into the first cavity and the second cavity described above;

[0069] Step 11: After the concrete has cured, the cup-shaped opening and the ground beam will be formed on the foundation 100.

[0070] Step 12: Remove the first clamping assembly 500 and the second clamping assembly 600, remove the inner mold 210, outer mold 220, bottom plate 310 and side plate 320, and dismantle the scaffolding 400.
