Description

Technical Field

[0001] The invention relates to a cavity system structure, in particular to a cavity system structure and a manufacturing method thereof. Background Art

[0002] The cavity (overlap, formwork, etc.) system is a building structure system that is mainly used for the manufacture and installation of prefabricated components. Its core feature is the use of cavity components, which are prefabricated in the factory and then assembled on site, thereby reducing the complexity and time of on-site construction. The structure of the cavity system is a prefabricated concrete slab on the outside and a cavity with a steel cage in the middle. The steel cage cooperates with the tie components to tie and fix the prefabricated concrete slabs on both sides. In the existing cavity system, most of the tie bars such as pre-buried tie bars or web bars are used for tie structures. However, the height of the welding points is easily inconsistent when the tie bars are manually welded. When pouring concrete, the depth of the tie bars in the concrete is also different. When the prefabricated concrete slab is subjected to an outward external force, the force will be directly transmitted to the welding point between the tie bars and the steel cage. Relying only on the fixation of the welding points makes the tension of the tie bars on the cavity system structure weak, and the stability of the cavity system structure is poor. Summary of the invention

[0003] In view of this, the present invention provides a cavity system structure and a manufacturing method thereof to solve the above technical problems.

[0004] The technical solution of the present invention is achieved in this way:

[0005] The present invention provides a cavity system structure, comprising a steel cage arranged in a rectangular column shape and a precast concrete slab located outside the steel cage, wherein a plurality of anchoring components are provided inside the steel cage, and connecting pieces are provided at both ends of the anchoring components, and the anchoring components are clamped with the steel cage through the connecting pieces, and the precast concrete slabs on the outside are connected to each other through the anchoring components, and the anchoring components comprise a connecting rod passing through the steel cage and an anchoring head connected to the precast concrete slab, and the anchoring heads are connected to each other through the connecting rod.

[0006] Preferably, the connecting member is a rectangular plate, the inner end of the rectangular plate is fixedly connected to the side wall of the anchor component, the outer end of the rectangular plate is bent toward the center side of the anchor component, and the rectangular plate is welded and fixed to the steel cage.

[0007] Preferably, the connecting member includes an upper clamping plate and a lower clamping plate, a clamping cavity is formed between the upper clamping plate and the lower clamping plate, the steel cage is clamped with the clamping cavity, and the outer ends of the upper clamping plate and the lower clamping plate are bent toward the center direction of the clamping cavity to form a duckbill-shaped clamping interface.

[0008] Preferably, the connecting members are arranged in a cross shape on the side walls of the anchoring component.

[0009] Preferably, the connecting rod is fixedly connected to the tie head.

[0010] Preferably, the connecting rod is detachably connected to the tie head, a threaded hole is provided at the center of the tie head, external threads are provided at both ends of the connecting rod, and the connecting rod is threadedly connected to the threaded hole.

[0012] Preferably, the precast concrete panels are arranged on both sides of the steel cage, and the two ends of the anchor component are connected to the precast concrete panels to form a cavity system wall structure.

[0013] Preferably, the precast concrete panels are connected in a "mouth" shape and covered on all sides of the outer side of the steel cage, the anchor components are horizontally cross-shaped and pass through all sides of the steel cage, the anchor components pointing forward and backward connect the precast concrete panels on the front and rear sides, and the anchor components pointing left and right connect the precast concrete panels on the left and right sides, forming a cavity system column structure.

[0015] S1: Make steel cage;

[0016] S2: making tie parts;

[0017] S3: Determine the type of cavity system to be produced;

[0018] If the cavity system structure is a wall structure, the tie components are fixed through both sides of the steel cage and placed on a casting platform so that the tie components stand on the top surface of the casting platform. Then, concrete is poured on the casting platform so that the tie heads at the bottom of the tie components are embedded in the concrete. After the concrete solidifies into a concrete slab, the concrete slab and the steel cage are turned over 180 degrees as a whole, and concrete is poured on the casting platform again so that the tie heads at the other end of the tie components are embedded in the concrete.

[0019] If the cavity system structure is a column structure, the tie parts are crisscrossed through the sides of the steel cage, and concrete is poured around the steel cage so that the tie heads on all sides are pre-embedded in the concrete.

DETAILED DESCRIPTION

[0032] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0033] See also Figures 1 to 6 The present invention provides a cavity system structure, including a steel cage 1 arranged in a rectangular column shape and a precast concrete slab 2 located outside the steel cage 1, wherein a plurality of anchoring components 3 are provided inside the steel cage 1, and connecting members 4 are provided at both ends of the anchoring components 3, and the anchoring components 3 are clamped with the steel cage 1 through the connecting members 4, and the precast concrete slabs 2 on the outside are connected to each other through the anchoring components 3, and the anchoring components 3 include a connecting rod 31 passing through the steel cage 1 and an anchoring head 32 connected to the precast concrete slab 2, and the anchoring heads 32 are connected to each other through the connecting rod 31.

[0034] By replacing the traditional embedded tie bars or web bars with the tie component 3, the setting of the tie head 32 can increase the contact area with the inside of the precast concrete slab 2, thereby improving the bite force of the tie head 32 on the concrete and increasing the pulling force on the precast concrete slab 2; and the traditional embedded tie bars or web bars are set on both sides of the steel cage 1, and can only play a unidirectional pulling effect on the precast concrete slab 2 on each side. The anchor component 3 connects and fixes the anchor heads 32 on both sides through the connecting rod 31 to form an integrated structure, which firmly connects the precast concrete slabs 2 on both sides. When the precast concrete slab 2 on the left side is about to deflect due to external force, the external force will also act on the precast concrete slab 2 on the right side, and the precast concrete slab 2 on the right side will also generate a reaction force to curb the deviation of the precast concrete slab 2 on the left side, thereby changing the tensile resistance provided by the original embedded tension bars or web bars to the tensile resistance provided by the anchor component 3 in cooperation with the precast concrete slab 2 on the other side, which greatly improves the tensile resistance effect, thereby improving the strength and stability of the cavity system wall structure.

[0035] For details, see Figure 3The connecting member 4 is a rectangular plate, one end of which is fixedly connected to the side wall of the anchor component 3, and the rectangular plate is welded and fixed to the steel cage 1. The rectangular plate can not only provide a welding point with the steel cage 1, but also play a supporting role for the steel bars when building the steel cage 1, thereby achieving rapid construction. The outer end of the rectangular plate is bent toward the center side of the anchor component 3, and the raised outer end can effectively prevent the steel bars from rolling off the connecting plate.

[0036] For details, see Figure 4 The connecting member 4 includes an upper clamping plate 41 and a lower clamping plate 42, and a clamping cavity 43 is formed between the upper clamping plate 41 and the lower clamping plate 42. The steel cage 1 is clamped with the clamping cavity 43, and the steel bars of the steel cage 1 are clamped into the clamping cavity 43. The steel bars are clamped and fixed by the upper clamping plate 41 and the lower clamping plate 42. The outer ends of the upper clamping plate 41 and the lower clamping plate 42 are bent toward the center direction of the clamping cavity 43 to form a duckbill-shaped clamping interface, thereby reducing the outlet height of the clamping cavity 43 and better locking the steel bars inside.

[0037] Specifically, the connectors 4 are arranged in a cross shape on the side walls of the anchoring component 3 , which can fix the steel bars on the left, right, front or rear sides, and can reduce the difficulty of adjusting the orientation of the connectors 4 when arranging the anchoring component 3 .

[0038] Specifically, the connecting rod 31 can be fixedly connected to the tie head 32 by welding, or by integrally formed fixed connection or other connection methods.

[0039] Specifically, the connecting rod 31 is detachably connected to the tie head 32, a threaded hole can be opened in the center of the tie head 32, both ends of the connecting rod 31 are provided with external threads, and the connecting rod 31 is connected to the tie head 32 by threaded connection, so that the connecting rod 31 of appropriate length can be used according to the required thickness of different cavity systems to achieve rapid assembly of the tie component 3.

[0040] Specifically, the cross-sectional diameter of the tie head 32 is larger than the cross-sectional diameter of the connecting rod 31, thereby forming a T-shaped structure with the connecting rod 31, increasing the volume of the tie head 32 embedded in the precast concrete slab 2, thereby improving the bite effect between the tie head 32 and the precast concrete slab 2, and the interior of the tie head 32 is axially provided with a through groove 5 for concrete to pass through, and the through groove 5 is arranged in a ring shape inside the tie head 32.

[0041] A method for manufacturing a cavity system structure comprises the following steps:

[0042] S1: making steel cage 1;

[0043] S2: making the tie-fastening component 3;

[0044] S3: Determine the type of cavity system to be produced;

[0045] If the cavity system structure is a wall structure, the tie component 3 is fixed through both sides of the steel cage 1 and placed on a casting platform so that the tie component 3 stands on the top surface of the casting platform. Then, concrete is poured on the casting platform so that the tie head 32 at the bottom of the tie component 3 is embedded in the concrete. After the concrete solidifies into a concrete slab, the concrete slab and the steel cage 1 are turned over 180 degrees as a whole, and concrete is poured on the casting platform again so that the tie head 32 at the other end of the tie component 3 is embedded in the concrete. After the concrete solidifies into a concrete slab, the production of the cavity system wall structure is completed.

[0046] See also Figure 1 and Figure 2 If the cavity system structure is a column structure, the tie parts 3 are crisscrossed through the sides of the steel cage 1, and concrete is poured around the steel cage 1 so that the tie heads 32 on all sides are pre-embedded in the concrete. After the concrete solidifies into a concrete slab, the production of the cavity system column structure is completed. The concrete pouring method includes a split pouring method and an integrated pouring method.

[0047] See also Figure 5 The split casting method is that the tie component 3 stands on the top surface of the casting platform, concrete is first poured on the casting platform, so that the tie head 32 is embedded in the concrete, and after the concrete solidifies into the first concrete slab, the concrete slab and the steel cage 1 are turned 90 degrees along the direction of the tie head 32, and concrete is poured on the remaining three surfaces of the steel cage 1 respectively, so that the concrete slabs on the four surfaces are connected to each other, and the tie heads 32 on the four surfaces are all embedded in the concrete. After the concrete is completely solidified into a concrete slab, the production of the cavity system column structure is completed;

[0048] See also Figure 6 The integrated casting method is to build a "U"-shaped, "concave"-shaped or U-shaped cavity template 6 around the steel cage 1, so that the template 6 is covered on the outside of the steel cage 1, and the tie head 32 is pre-embedded in the inside of the template 6, and then concrete is poured into the template 6. After the concrete solidifies into a concrete slab, the production of the cavity system column structure is completed.

[0049] In addition, when pouring concrete, grilles or meshes made of materials such as basalt can be added to prevent cracking on the surface of the formed wall or column, and to prevent rust on the surface of the wall or column in the later stage.

[0050] It should be noted that the cavity system mentioned in the present application includes cavity systems such as composite wall (column) system and formwork wall (column) system.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
