In the present embodiment, the first tie structure 300 is provided with the bolt 310, and the second tie structure 400 is provided with the nut 410, but in other embodiments, the first tie structure 300 may be provided with the nut 410, the second tie structure 400 may be provided with the bolt 310 and the connecting bracket 420, and when the sandwich portion is placed in the vertical mold 10, the bolt 310 is passed through the bottom mold 100, and the nut 410 is screwed to the bolt 310 from the outside. After demolding, a threaded sleeve is arranged at the end of the lifting appliance, and the sandwich plate member can be lifted by screwing the bolt 310 into the threaded sleeve.

In the drawing of the present embodiment, only a single first tie structure 300 and a single second tie structure 400 are shown, when in use, a plurality of first tie structures 300 may be arranged along the extending direction of the bottom die 100 as required, a plurality of second tie structures 400 may be arranged along the extending direction of the sandwich panel member as required, and the connecting brackets 420 of a plurality of second tie structures 400 may also be configured to be connected into a whole, for example, two adjacent connecting brackets are welded together by a steel bar, so as to further enhance the integrity of the sandwich panel member and enhance the position stability of the sandwich portion in the forming cavity of the vertical die 10.

Aforementioned steel bar framework includes two reinforcing bar net piece 500 and transverse connection member 600, two reinforcing bar net piece 500 set up the both sides at core 700, reinforcing bar net piece 500 can retrain the concrete thick liquids and strengthen its adhesive force, can also increase the tensile strength of sandwich panel member, the face that makes the sandwich panel member is difficult to the fracture, and guarantee the wholeness ability and the shock resistance of sandwich panel member, and transverse connection member 600 wears to locate core 700, and transverse connection member 600's both ends are connected with two reinforcing bar net piece 500 respectively, combine aforementioned, know easily, the pulling force that prevents core 700 come-up is finally transmitted for core 700 by transverse connection member 600.

The number of the transverse connectors 600 may be multiple, during the setting, the maximum tensile force that can be provided by a single transverse connector 600 is calculated according to the maximum stress that can be borne by the material of the core plate 700 and the force transfer area between the transverse connector 600 and the core plate 700, and then the maximum buoyancy that the core plate 700 may be subjected to is estimated according to the density and the volume of the core plate 700 and the density of the concrete slurry, where the ratio of the maximum buoyancy to the maximum tensile force is the minimum number of the transverse connectors 600, and during the actual setting, the number of the transverse connectors 600 may be slightly increased compared with the minimum number.

For the convenience of installation, a plurality of first holes 710 are formed in the core plate 700, the first holes 710 are used for allowing the transverse connectors 600 to pass through, and the first holes 710 can be arranged to avoid the accident that the transverse connectors 600 are directly inserted into the core plate 700 to cause irregular damage to the core plate 700, thereby improving the durability of the core plate 700. Further, a sleeve is arranged in the first hole 710, and the sleeve is blocked between the transverse connector 600 and the hole wall of the first hole 710 to protect the hole wall of the first hole 710, so that the core plate 700 is not easily split and damaged from the hole wall when the transverse connector 600 contacts the hole wall to transmit a pulling force downwards. Moreover, by arranging the sleeve, the structural strength of the hole wall is improved, the maximum tensile force which can be transmitted by a single transverse connecting piece 600 is increased, the number of the transverse connecting pieces 600 can be relatively reduced, and materials and labor are saved.

The material of the sleeve can be various, such as PVC material, metal, steel pipe, etc.

The cross-connecting member 600 may be a short reinforcing bar, which passes through the core plate 700, and both ends of which extend to the position of the reinforcing mesh 500, and are fixed with the reinforcing mesh 500 by binding or welding. Further, the two ends of the steel bars are fixed at the crossing positions of the longitudinal and transverse steel bars of the steel bar mesh sheet 500, so that the structural strength of the steel bar mesh sheet 500 is improved, and the steel bar mesh sheet 500 is further not easy to deform.

When the concrete is poured into the molding cavity of the vertical mold 10, the concrete slurry on the two sides of the core plate 700 is not equal, the pressure generated by the concrete slurry on the two sides of the core plate 700 is not equal, and when the pressure difference between the two sides of the core plate 700 is large, the core plate 700 is easy to deform, so that the internal condition of the molding cavity needs to be closely concerned during pouring, so that the concrete slurry on the two sides of the core plate 700 is approximately increased, and the labor is consumed. In order to solve the technical problem, the core plate 700 is provided with the second holes, the second holes are used for balancing concrete slurry on two sides of the core plate 700 during grouting, when the concrete slurry on two sides of the core plate 700 is unequal, one side with more concrete slurry can flow to the other side through the second holes, so that the effect that the pressure of two sides of the core plate 700 is adjusted to be approximately balanced in a self-adaptive manner is achieved, and the core plate is prevented from being damaged easily due to unbalanced fluid impact force and the quality of the sandwich structure plate is influenced.

When the number of holes provided in the core plate 700 is too large, the ratio of the total area of the holes to the area of the core plate 700 is too large, and the performance of the core plate 700 may be reduced, for example, the structural strength of the core plate 700 itself may be reduced, which may reduce the durability of the sandwich panel member, and the sound insulation and heat insulation effects of the core plate 700 may be reduced, which may reduce the use experience of the sandwich panel member. However, when fewer holes are provided in core plate 700, fewer cross-connectors 600 can be provided, and the greater the force between a single cross-connector 600 and core plate 700 with the same buoyancy, this can result in excessive local stress on core plate 700 and damage.

In order to take account of the structural strength, the sound and heat insulating ability of the core plate 700, the maximum local stress generated when the core plate 700 floats, and the ability of self-adaptive pressure balancing when grouting, the total area of the holes on the core plate 700 is configured to be 5% -10% in the present embodiment.

The sandwich portions of the vertical mold 10 and the sandwich plate member may be fabricated on site, or may be fabricated in advance in a factory, or further, the molding system may be fabricated in advance in a factory, and the concrete slurry may be directly poured into the molding system during production, and the mold may be removed after the concrete slurry is solidified.

The concrete slurry in this embodiment may be ultra-high performance concrete, foamed concrete, ceramsite concrete, or other hardenable fluid filler such as EPS (Expanded Polystyrene foam).

The present embodiment also provides a production process of the sandwich panel member, and the following is a description of the production process.

Manufacturing a vertical mold 10: four side molds 200 are connected with a bottom mold 100 to form a molding cavity with a pouring opening at one end, and a through hole is formed in the bottom film.

Making a sandwich part: the plurality of transverse connectors 600 are arranged on the core plate 700 in a penetrating mode, the plurality of transverse connectors 600 are evenly distributed on the surface of the core plate 700, the two reinforcing mesh pieces 500 are arranged on two sides of the core plate 700, two ends of each transverse connector 600 are connected with the two reinforcing mesh pieces 500 respectively, then two side portions of the connecting support 420 of the second knotting structure 400 are welded with the two reinforcing mesh pieces 500 correspondingly, and the nut 410 of the second knotting structure 400 is located on one side, far away from the core plate 700, of the connecting support 420.

When the sandwich part is manufactured, a gap may be further formed between the mesh sheet 500 and the core plate 700. The gap enables the steel mesh 500 and the core plate 700 not to contact as much as possible, and in the later use process, the steel mesh 500 is not easy to rub the core plate 700 to cause damage when the sandwich plate member is stressed and deflected, so that the durability of the sandwich plate member is improved. And when the subsequent pouring molding is carried out, the reinforcing mesh 500 and the core plate 700 can be fully wrapped by concrete slurry respectively, so that the filling dead angle is reduced, the possibility of generating a hollow hole and an uncompacted part in the sandwich plate member is reduced, air bubbles in the molding cavity can be discharged as far as possible, the excessive oxidation of the reinforcing mesh 500 is prevented, and the quality and the durability of the sandwich plate member are improved.

Alternatively, the holes in the core plate 700 may be drilled in the core plate 700 before the reinforcing mesh 500 is fixed, and the holes for arranging the cross-connectors 600 are inserted into the sleeves to form the first holes 710, and the remaining holes are used as the second holes. It is also possible to purchase the core plate 700 directly with the holes and insert the bushings into the holes where the cross-connectors 600 are to be arranged.

Manufacturing a molding system: the sandwich portion is put into the molding cavity of the vertical mold 10 from the pouring opening of the vertical mold 10 such that the nut 410 corresponds to the through hole of the bottom mold 100, and then is coupled to the nut 410 through the through hole using the bolt 310 of the first tie structure 300 and tightened.

Pouring and forming: placing the molding system with the pouring opening of the vertical mold 10 facing upwards, pouring concrete slurry into the molding cavity from the pouring opening of the vertical mold 10, loosening the bolt 310 to separate the bolt from the nut 410 after the concrete slurry is solidified and hardened, and demolding to obtain the sandwich plate member.

The end of the spreader is threaded onto the nut 410 to hoist the sandwich panel member.

It should be noted that the step of making the vertical mold 10 and the step of making the sandwich portion may be performed simultaneously or sequentially, and the step of making the vertical mold 10 and the step of making the sandwich portion may be switched sequentially, for example, the sandwich portion is made first, and then the split side mold 200 and the bottom mold 100 are disposed at the periphery of the sandwich portion to form the vertical mold 10, and the first tie structure 300 and the second tie structure 400 are connected.

During casting, the reinforcing mesh 500 may be bent due to the pressure generated by the concrete slurry, such as the upward force transmitted by the core plate 700 through the cross connection member 600, and the unbalanced pressure in the transverse direction. Further, two ends of a longitudinal steel bar of the steel bar mesh sheet 500 penetrate out of the bottom die 100 and the pouring opening, two ends of a transverse steel bar of the steel bar mesh sheet 500 penetrate out of the corresponding side die 200, holes with diameters approximately the same as those of the longitudinal steel bar and the transverse steel bar can be drilled in the bottom die 100 or the side die 200, then the two ends of the longitudinal steel bar and the two ends of the transverse steel bar are respectively connected through a tensioning mechanism, and in the pouring forming step, force is always applied to the longitudinal steel bar and the transverse steel bar through the tensioning mechanism, so that the longitudinal steel bar and the transverse steel bar are kept in a prestressed stretched state and are not easy to bend. After the tensioning mechanism applies enough prestress, the two ends of the longitudinal steel bar and the two ends of the transverse steel bar can be fixed by other anchoring devices respectively, and then the tensioning mechanism is removed.

After demoulding, the extending parts of the longitudinal steel bars and the transverse steel bars can be cut off, and the pulling device can be used for connecting one end of each steel bar and pulling out the steel bars.

Example 2:

on the basis of embodiment 1, the aforementioned transverse connection member 600 may also be configured as a structure shown in fig. 8.

The transverse connecting member 600 comprises a connecting rod 610 and two clamping pieces 620, the connecting rod 610 penetrates through the core plate 700, and the two clamping pieces 620 are arranged at two ends of the connecting rod 610 and are used for being clamped with the reinforcing mesh piece 500.

The connecting rod 610 and the two clamping pieces 620 can be integrally formed or fixedly connected, and in this embodiment, the connecting rod 610 and the two clamping pieces 620 are in an insertion structure so as to facilitate field installation.

As shown in fig. 9, sockets are formed at both ends of the connecting rod 610, and after the connecting rod 610 is inserted into the core plate 700, two fasteners 620 are respectively inserted into both ends of the connecting rod 610, and the fasteners 620 are fastened on the reinforcing steel bars.

The clamping piece 620 comprises a limiting plate, four clamping nails are formed on one surface of the limiting plate, cross clamping grooves used for accommodating the reinforcing steel bars are formed among the four clamping nails, a plug is formed on the other surface of the limiting plate, and the plug can be in plug-in fit with the socket of the connecting rod 610. The staple can block on vertical reinforcing bar, also can block on horizontal reinforcing bar, can also block in the crossing position of vertical reinforcing bar and horizontal reinforcing bar simultaneously.

When the steel bar net piece is installed, the plug of one clamping piece 620 is inserted into the socket, the clamping piece is clamped on the steel bar net piece 500, and then the other clamping piece 620 is processed by the method. The transverse connecting piece 600 has the characteristics of simple and quick connecting mode, and the two clamping pieces 620 can be abutted against the reinforcing mesh sheet 500 to prevent the connecting rod 610 from sliding in the core plate 700, so that the position of the core plate 700 is further limited, and the positioning precision is improved.

Further, the length of the connecting rod 610 is configured to be substantially the same as the thickness of the core plate 700, so that after the clamping piece 620 is inserted on the connecting rod 610, the limiting plate abuts against the core plate 700 to limit the sliding of the connecting rod 610, a better positioning effect is achieved, and the contact between the reinforcing mesh 500 and the surface of the core plate 700 can be limited to form a gap.

In addition, when the buoyancy is small and the force applied to the single cross-connecting member 600 is not large, the sleeve inserted into the first hole 710 may be directly used as the connecting rod 610.

Example 3:

on the basis of embodiment 1, the aforementioned reinforcing bar framework can also be configured as fasteners 800, the fasteners 800 are fastened to both sides of the core plate 700, and the fasteners 800 on both sides of the core plate 700 are connected to the second tie structure 400.

The structure of the fastening member 800 may be as shown in fig. 10, and includes a plurality of steel bars, each of which is formed with a raised insertion portion 810, the insertion portion 810 having a tip end for inserting into the core 700, so that the fastening member 800 can be fastened to the surface of the core 700.

The insertion part 810 is configured to have an arrow-shaped structure having a tip and a boss formed behind the tip, and since the core plate 700 is made of a material having a high shrinkage elasticity (such as XPS), after the insertion part 810 is inserted into the core plate 700, the arrow-shaped structure is submerged into the core plate 700, the socket formed on the surface of the core plate 700 is shrunk, and the arrow-shaped structure is not easily separated from the core plate 700 under the limitation of the boss, so that the fixing effect is good. Alternatively, the boss may be a plurality formed behind the tip.

Further, the insertion portion 810 has a flat sheet structure, which allows the arrow-shaped structure to be inserted only by forming a narrow opening in the surface of the core plate 700, and the insertion opening is more easily contracted. Moreover, the flat insertion part 810 is arranged parallel to the bottom mold 100 to increase the action area of the insertion part 810 and the core plate 700, so as to reduce the local stress and make the core plate 700 not easy to be damaged.

The number of the fasteners 800 may be configured in plural, and a plurality of the fasteners 800 are respectively disposed at each surface of the core plate 700. Each fastener 800 is connected to the second tie structure 400.

Since the fasteners 800 are not directly connected to each other, the sandwich portion formed by the core 700 and the fasteners 800 is easily bent or shifted left and right, and in order to further improve the position accuracy, a convex abutting portion 820 is formed on one surface of each steel bar facing the side mold 200, and the abutting portion 820 is used for abutting against the side mold 200. After the sandwich part is placed into the forming cavity, the abutting parts 820 on the fasteners 800 at two sides of the core plate 700 abut against the corresponding side dies 200, so that the whole sandwich part is not easy to bend or shift left and right.

The inserting part 810 and the supporting part 820 on the fastener 800 can be formed separately and then welded to the steel bar, or formed integrally, in this embodiment, the manufacturing method of the fastener 800 is as follows: the inserting part 810 and the abutting part 820 are punched on the steel bar, one end of the inserting part 810 and one end of the abutting part 820 are still connected to the steel bar, and then the inserting part 810 and the abutting part 820 are respectively flanged towards two sides of the steel bar.

Optionally, the insertion part 810 and the abutting part 820 may be formed separately and then directly disposed on the steel mesh 500 in embodiment 1, so that the steel mesh 500 can be directly connected to the core plate 700 through the insertion part 810, instead of the transverse connector 600, to further accelerate the installation of the steel mesh 500.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
