Description

Technical Field

[0001] The utility model relates to the technical field of granary construction, in particular to an assembled steel-concrete bulk grain building warehouse. Background Art

[0002] As a new type of grain storage warehouse, building warehouse has many advantages such as high space utilization and small footprint. However, most of the current bulk grain building warehouses are cast-in-place structures. When building grain building warehouses, construction workers need to build steel bars on site and then pour concrete. This type of grain building warehouse has the following shortcomings:

[0003] 1. Since all parts need to be prepared and assembled on site by construction workers before they can be poured, this not only greatly increases the workload of construction workers, but also seriously affects the construction efficiency of grain warehouses;

[0004] 2. The on-site preparation of components takes a long time and requires more production and processing equipment, which will cause greater environmental pollution during the long construction process;

[0005] Therefore, there is an urgent need for an assembled steel-concrete bulk grain building warehouse that can be quickly assembled on site. Utility Model Content

[0006] In order to overcome the shortcomings of the background technology, the utility model discloses an assembled steel-concrete bulk grain building warehouse, which can achieve the purpose of rapid on-site assembly. At the same time, the beam-column node parts and part of the plate are cast on-site, which improves the construction speed, shortens the construction period and reduces the construction cost under the premise of ensuring the air tightness of the structure.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An assembled steel-concrete bulk grain building warehouse, comprising:

[0009] The columns are cast-in-situ steel-concrete columns, and the inner steel in the columns is cross-shaped steel;

[0010] The main beam is a prefabricated steel-concrete beam. The inner steel of the main beam is H-shaped steel. A cast-in-place concrete area is reserved at the connection between the main beam and the column, and the remaining area of ​​the main beam is prefabricated with concrete.

[0011] The wall body is prefabricated by an inner leaf wall, an outer leaf wall, and an insulation board arranged between the inner leaf wall and the outer leaf wall;

[0012] The silo bottom plate is formed by pouring concrete on corrugated steel plate;

[0013] A plurality of columns, main beams, walls and warehouse bottom plates are assembled to form a multi-layer structure of bulk grain building warehouse.

[0014] Furthermore, inner column stirrups 11 are evenly distributed on the outer side of the inner column steel section, and the inner column steel section 10 and the inner column stirrups 11 cooperate to form a cast-in-place portion.

[0015] Furthermore, the insulation board is an extruded polystyrene board.

[0016] Furthermore, both sides of the wall are provided with evenly arranged buckle bars.

[0017] Furthermore, an L-shaped rib is provided on the upper side of the wall, and a corrugated pipe is provided on the lower side of the wall.

[0018] Furthermore, a mortar layer is provided on the upper part of the wall 1 connected to the main beam.

[0019] Furthermore, the upper and lower parts of the inner steel sections in the main beam are respectively provided with upper longitudinal bars and lower longitudinal bars arranged along the axial direction of the main beam, and the two ends of the upper longitudinal bars and the lower longitudinal bars are respectively connected to adjacent columns.

[0020] Furthermore, the main beam is provided with a plurality of steel secondary beams which are arranged in an orderly manner along the axial direction of the main beam and are perpendicular to the main beam.

[0021] Furthermore, shear bolts are provided on the upper portion of the steel secondary beam.

[0022] Furthermore, upper and lower corresponding wall connections are respectively provided with upper and lower hidden beams.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] By setting cast-in-place parts at both ends of the main beam, it is not only convenient for the subsequent connection and installation of the main beam and the column, but also the on-site joint casting method can ensure that the building warehouse has reliable mechanical properties and good air tightness;

[0025] The wall body is composed of inner leaf wall, outer leaf wall and insulation board, so as to ensure that the building warehouse has good resistance to environmental dormitory and grain loading machinery, and at the same time has excellent fire resistance performance, meeting the fire resistance requirements of the building warehouse;

[0026] By setting up the mortar layer, the density between the main beam and the wall can be effectively improved to enhance the air tightness, while reducing the workload of on-site construction;

[0027] By setting up steel secondary beams and shear bolts, the firmness and stability of the warehouse floor can be ensured, and slippage between the floor floor and the steel secondary beams can be avoided;

[0028] The utility model realizes the purpose of production in factory and rapid assembly on site by adopting factory production and assembly of most components in the building warehouse system. At the same time, the beam-column node parts and some plates are cast on site, which improves the construction speed, shortens the construction period and reduces the construction cost under the premise of ensuring the air tightness of the structure. At the same time, compared with the traditional building warehouse, the addition of steel sections makes the assembled building warehouse have better earthquake resistance and is suitable for high-intensity areas.

In the description, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present invention and are for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0040] Please refer to the instruction manual Figure 1-6 , the utility model provides a technical solution:

[0041] Embodiment 1, a prefabricated steel-concrete bulk grain building warehouse, comprising:

[0042] The column is a steel-concrete column cast on site, the inner column steel 10 in the column is a cross-shaped steel, and inner column stirrups 11 are evenly distributed on the outer side of the inner column steel 10;

[0043] The main beam is a prefabricated steel concrete beam. The inner beam steel 12 in the main beam is an H-shaped steel. The outer side of the inner beam steel 12 is evenly distributed with inner beam stirrups 14. The upper and lower parts of the inner beam steel 12 in the main beam are respectively provided with upper longitudinal reinforcement and lower longitudinal reinforcement arranged along the axial direction of the main beam. A cast-in-place concrete area is reserved at the connection between the main beam and the column. The remaining area of ​​the main beam is cast with the prefabricated part of the beam concrete 16, thereby completing the prefabrication of the main beam;

[0044] The wall 1 is prefabricated by an inner leaf wall, an outer leaf wall, and an insulation board arranged between the inner leaf wall and the outer leaf wall. The insulation board is an extruded polystyrene board. Both sides of the wall 1 are provided with evenly arranged buckle ribs 4. The upper side of the wall 1 is provided with an L-shaped rib 3. The lower side of the wall 1 is provided with a corrugated pipe 2.

[0045] The silo bottom plate is formed by pouring concrete on the corrugated steel plate 17;

[0046] A plurality of columns, main beams, walls and warehouse bottom plates are assembled to form a multi-layer bulk grain building warehouse. Specifically, column inner stirrups 11 are evenly distributed on the outer side of the column inner steel 10. The column inner stirrups 10 and the column inner stirrups 11 cooperate to form a cast-in-place part 9. When the cross-shaped steel of the upper and lower parts of the column inner steel 10 are connected, the flange is first welded to the web, and then the web welding seam is anchored with a bolt anchor plate. After the plurality of columns are distributed in a rectangular shape, a plurality of prefabricated main beams are installed between the corresponding columns. Multi-layer main beams can be arranged according to the number of floors of the building warehouse. The ends of the main beams are connected to the columns and the gusset plates by bolts. A cast-in-place area is left at the connection between the main beams and the columns. The ends of the upper longitudinal reinforcement and the lower longitudinal reinforcement in the main beam are respectively connected to the adjacent columns.

[0047] The main beam is provided with a plurality of steel secondary beams 19 which are arranged in an orderly manner along the axial direction of the main beam and are perpendicular to the main beam. The steel secondary beams can be welded to the main beam. When installing the warehouse floor, the corrugated steel plate 17 in the warehouse floor is first installed on the main beam and the upper part of the steel secondary beam 19. In order to prevent the corrugated steel plate 17 from slipping on the steel secondary beam 19, the upper part of the steel secondary beam 19 is provided with shear bolts 18 connected to the warehouse floor;

[0048] When installing the wall 1 between adjacent columns, it is generally installed by splicing multiple layers of the wall 1 up and down. After the buckle bars 4 on both sides of the wall 1 are inserted into the columns, the longitudinal bars in the columns are placed to form an effective connection. The outer side of the corrugated pipe 2 on the lower side of the wall 1 is provided with spiral stirrups. The longitudinal bars of the L-shaped bars 3 on the upper part of the lower wall 1 are placed in the outer spiral stirrups of the corrugated pipe 2 on the lower side of the upper wall 1. After the upper and lower walls 1 are calibrated and aligned, mortar is injected into the reserved grouting holes of the corrugated pipe 2 to form a whole. In order to improve the air tightness between the walls 1, the upper and lower corresponding wall 1 connections are respectively provided with cast upper hidden beams 5 and lower hidden beams 6. The upper hidden beams 5 and the lower hidden beams 6 are provided with reserved stirrups 7 for hidden beams. The reserved stirrups for hidden beams are not only used to strengthen the connection between the upper and lower walls 1, but also to ensure the casting of the upper hidden beams 5 and the lower hidden beams 6.

[0049] A mortar layer 8 is provided at the connection between the upper side of the wall and the main beam at the lower part of the main beam. During on-site construction, the beam and the wall do not need to be connected with steel bars. The mortar layer 8 improves the density between the main beam and the wall, thereby enhancing air tightness and reducing on-site construction workload.

[0050] After the installation of the columns, main beams, walls 1 and corrugated steel plates 17 is completed, the corrugated steel plates 17 can be installed at the upper end to cap the roof, and the cast-in-place parts 9 reserved for the columns can be used to pour concrete. The concrete fills the connection between the columns and the main beams, and then the corrugated steel plates 17 are poured to form the warehouse bottom plate, thereby completing the construction of the grain building warehouse.
