Description

Technical Field

[0001] The invention relates to a building component, in particular to a building component used for a backfilling groove in a construction project, specifically to a filling body structure used for a backfilling groove in a construction project. Background Art

[0002] During the construction of the construction project structure, there is often a trench with a width of 1 to 2 meters and a depth of 3 to more than 10 meters between the basement outer wall and the foundation pit retaining piles. When the construction height of the building structure exceeds ±0.00, the surrounding trench can be backfilled.

[0003] The trenches around the building structure are often backfilled with soil, and concrete is poured on the surface to harden. However, in the rainy season, the backfill soil is easy to seep water, or there is groundwater in the soil layer, which causes the backfill soil in the trench to sink, resulting in cracks or even collapse of the hardened concrete on its surface, affecting the surrounding environment of the building. In addition, in buildings along the rail transit line, it is often required that a backfill body that can reduce the vibration and noise of rail transit operation should be set on the outside of the building basement, and some high-quality housing buildings also require that the outer backfill body of the building basement should have the function of resisting vibration and noise from the surrounding area and heat insulation, and the use of soil backfill trenches obviously cannot meet the above requirements. In order to avoid the above problems and achieve the above functions, concrete is currently backfilled in the above trenches. However, this will directly increase the cost of engineering materials. Moreover, the concrete production process consumes a lot of energy, which also indirectly increases carbon dioxide emissions.

[0004] Therefore, there is an urgent need to improve the existing technology so that it can not only meet the requirements of building design, but also reduce the amount of concrete used and achieve energy conservation and environmental protection. Summary of the invention

[0005] The purpose of the present invention is to provide a filling body structure for backfill grooves in construction projects in response to the current problems in the construction of backfill grooves around buildings. The filling body structure can be filled into the backfill groove together with concrete, which can not only fully meet the needs of building functions, but also effectively reduce the amount of concrete used, reduce the cost of engineering materials, and indirectly reduce carbon dioxide emissions. It also has the functions of sound absorption and vibration reduction, heat insulation and heat preservation, thereby achieving energy saving and environmental protection.

Implementation

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1 to 7 shown.

[0027] A filling body structure for backfilling trenches in construction projects includes a body 7, cables 4-5, and a suspension device. The inner wall of the backfilling trench 5 is a basement outer wall 6, and the outer wall thereof is a retaining pile 2. The outer side of the retaining pile 2 is a soil layer 1.

[0028] The main body 7 is hollow cylindrical, and its size is adapted to the backfill groove 5, so that it can be placed in the backfill groove 5 of the construction project, and the gap between it and the wall of the backfill groove 5 is 100-150mm, which meets the needs of pouring concrete construction. The interior of the main body 7 is filled with content 7-4. The content 7-4 is made of organic materials such as foamed polyurethane, so that the interior of the main body 7 is filled to form a whole, so as to resist the concrete side pressure on its outer surface without being concave, and the organic foam material used in the content has good sound absorption and vibration reduction, heat insulation and heat preservation functions. The density of the content can be determined according to the burial depth. At the same time, a through hole 7-5 is reserved at the center line of the content to facilitate subsequent assembly.

[0029] The outer periphery of the body 7 is provided with an annular protruding rib 7-3. The ribs 7-3 are multiple, arranged at intervals in the transverse direction and parallel to each other, so that the body 7 has the ability to fully resist the horizontal lateral pressure of the external concrete. The body 7 and the ribs 7-3 can be formed by injection molding in one step, which is convenient for production. The foam material filled inside can further increase the compressive resistance of the body, and its specific gravity and strength can be selected and determined according to the embedding depth, that is, the external pressure to be borne.

[0030] The two ends of the main body 7 are provided with connecting parts. The connecting part is a cylindrical protrusion, provided with external threads and / or internal threads. In this embodiment, the connecting part located at the upper end of the main body is an internal threaded tube 7-1 provided with internal threads, and the connecting part located at the lower end of the main body is an external threaded column 7-2 provided with external threads, so that the main bodies can be screwed together through threads to form a body component with a "sugar-coated haws" structure, so as to adapt to the depth of the backfill groove, and the vertical spacing after assembly can achieve a larger filling rate to replace more concrete. Preferably, the connecting part is centrally arranged to facilitate the screwing operation.

[0031] The cables 4-5 are steel wire ropes which can pass through the body 7 or the body assembly along the perforations and can fully prevent the body from floating up and resist unilateral vibration and impact during construction, so that the body 7 can be kept in the installed position.

[0032] The suspension device includes a suspension frame 3 and a suspension structure 4. The suspension frame 3 is composed of a fixing rod 3-1, a suspension beam 3-2 and a diagonal rod, all of which are steel sections, which are welded or bolted to each other into a right-angled triangle shape to form a stable structure. The suspension beam 3-2 is located at the bottom and is made of an I-beam; the fixing rod 3-1 is located on the side and is made of a channel steel, and is installed on the retaining pile 2 by an anchor bolt 11. Preferably, the opening of the fixing rod 3-1 faces the supporting pile 2, which can adapt to the cylindrical shape of the supporting pile 2, and reduce the verticality of the fixing rod 3-1 by the uneven surface of the supporting pile 2 during installation by reducing the contact surface.

[0033] The suspension structure includes a suspension plate 4-1. The suspension plate 4-1 is in the shape of a "door" and is hung on the suspension beam 3-2. It can slide along the suspension beam as needed to make the cable 4-5 in a vertical state. A suspension pin 4-3 is provided at the lower opening of the suspension plate 4-1. A positioning retaining ring 4-2 and a basket bolt are provided on the suspension pin 4-3. There are two positioning retaining rings 4-2, which are respectively arranged on both sides of the basket bolt 4-4 to ensure that the basket bolt 4-4 is installed in the center. The upper end of the cable 4-5 is fixed by an aluminum compression tube 4-6 after passing through the basket bolt 4-4. The aluminum compression tube is a short double-hole tube. The end of the cable 4-5 passes through one hole of the aluminum compression tube, passes through the basket bolt 4-4, and then passes through the other hole of the aluminum compression tube. A special compression clamp is used to extrude and deform the aluminum compression tube 4-6 so that it is tightly embedded with two strands of steel wire ropes, so that the annular end of the cable is effectively fixed.

[0034] A U-shaped top support plate 4-9 is also provided inside the suspension plate 4-1. The U-shaped top support plate 4-9 is located between the lower flange of the suspension beam 3-2 and the suspension pin 4-3, is connected to the side wall of the suspension plate 4-1 through a connecting bolt 4-10, and is pressed against the bottom surface of the suspension beam 3-2 in the middle through a top support bolt 4-8 to prevent the suspension plate 4-1 from sliding along the suspension beam 3-2.

[0035] The building bottom plate 8 of the backfill groove 5 is provided with an O-type anchor bolt 9. The lower end of the cable 4-5 passes through a hole of the aluminum compression tube, bypasses the O-type anchor bolt 9, and then passes through another hole of the aluminum compression tube. Then, the aluminum compression tube 4-6 is squeezed and deformed to fit tightly with the two steel wire ropes, so that the lower end of the cable is firmly fixed.

[0036] Furthermore, it also includes a pad 4-7. The pad 4-7 is in the shape of a flat plate and is provided with mounting holes, which can be sleeved on the two ends of the cable 4-5. At the same time, the diameter of the mounting hole is smaller than the outer dimensions of the aluminum compression tube 4-6, so that the aluminum compression tube 4-6 can be pressed against the pad 4-5, and then the pad 4-5 is pressed against the connecting part, ensuring that the cable 4-5 can clamp the body 7 or the body assembly.

[0037] The method of use of the present invention is: According to the design requirements of the backfill slot of the construction project, the production of different components is completed in the factory. Then, it is transported to the construction site, and the cables are passed through the designed number of bodies and connected and assembled with each other, so that the minimum clear distance between adjacent bodies is about 0.1m. Then, the suspension frame is installed on the retaining piles with anchor bolts, and O-type anchor bolts are installed at the bottom of the building foundation backfill slot 5; then, the two ends of the cable are connected to the suspension frame and the O-type anchor bolts respectively, and the cable is ensured to be vertical by adjusting the suspension plate. Then, the two ends of the cable are anchored with aluminum compression tubes, and the aluminum compression tubes are pressed against the upper and lower ends of the pad and the body assembly. At the same time, the basket bolts are adjusted to tighten the cable, so that the body remains in the installation position and has the ability to resist the vibration impact load when pouring concrete. Then, concrete 10 is injected into the backfill slot 5 of the construction project for backfilling until the design elevation.

[0038] After pouring, when the concrete solidifies and reaches the required strength, the suspension device is removed and the backfill construction is completed.

[0039] The present invention can backfill the backfill groove of the construction project together with the main body and the backfill concrete 10, and prevent the main body from floating or shifting when backfilling and pouring concrete through the pulling effect of the cable. Therefore, the amount of backfill concrete 10 can be effectively reduced, the construction cost can be reduced, and the emission of carbon dioxide can be indirectly reduced. Moreover, although the backfill concrete 10 is partially replaced by the main body with large organic elastic thermal resistance, it can still maintain sufficient overall strength and ground endurance, and has good noise reduction, vibration reduction, heat insulation and heat preservation functions, achieving the purpose of energy saving and environmental protection.

[0040] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art.
