Description

Technical Field

[0001] The invention relates to the technical field of concrete floor slabs, and in particular to a prefabricated concrete composite floor slab. Background Art

[0002] The composite floor is an assembled integral floor made of prefabricated panels and cast-in-place reinforced concrete layers. The main materials are concrete and steel bars. During subsequent processing, the steel bars are used to fix the floor, and then the gaps are poured to fix the floor and the building to complete the construction.

[0003] The composite floor slabs currently used have the following disadvantages: 1. The floor slab made of concrete and steel bars only provides load-bearing function, and seismic gaps need to be set to buffer the vibration of the floor slab, which will lead to reduced strength and lack of shock-absorbing function that can avoid affecting the strength of concrete; 2. The floor structure is simple. If the heating needs to be pre-laid, the floor strength will be reduced or the thickness will be increased, thereby reducing the practical space and lacking the temperature control function that does not affect the space; 3. Lack of thermal insulation effect and lack of controllable thermal insulation function. Summary of the invention

[0004] In view of this, the present invention provides a prefabricated concrete composite floor, which has a hollow beam frame that can be used for heating. The interior of the hollow beam frame can be filled with water for circulation, and a heater and a drive assembly are connected in series, so that it can be used as floor heating. A circulation channel is formed by a guide edge, thereby facilitating the interconnection between each group of hollow beam frames. If circulating water is selectively filled in the steel wire hose and the interior of the hollow beam frame and heated, it can be used as floor heating. There is no need to lay additional floor heating space, making the living environment more suitable.

[0005] The present invention provides a prefabricated concrete composite floor slab, specifically comprising a main body floor slab, which is a prefabricated part, and is cast by a rectangular formwork, and a steel beam frame connected by steel bars is cast in the middle of the main body floor slab; a trapezoidal module is integrally arranged on the outside of the main body floor slab; the trapezoidal module is a trapezoidal structure; two groups of main body floor slabs can be oppositely combined through the trapezoidal module; four groups of docking grooves are opened on the adjacent side edges of the two groups of main body floor slabs; a hollow beam frame, and docking pins aligned with the docking grooves are integrally arranged on the upper and lower ends of both sides of the hollow beam frame, and the docking pins can be inserted into the docking grooves in a matching manner.

[0006] Optionally, the length and width of the upper base of the trapezoidal module are shorter than the length and width of the lower base.

[0007] Optionally, a dovetail groove for assembly connection is provided in the middle of the sides of the hollow beam frames, and two groups of hollow beam frames can be fixedly connected by providing a splicing block that matches the dovetail groove.

[0008] Optionally, the middle of the hollow beam frame is a comb-like structure, the interior of the hollow beam frame is a hollow structure, and a guide edge is integrally provided inside the hollow beam frame, and the hollow beam frame forms a uniform circulation channel through the guide edge.

[0009] Optionally, a steel wire hose is provided in the middle connection of both sides of the hollow beam frame, a connecting seat is fixedly provided at the end of the steel wire hose, a flange structure is integrally provided on the outside of the connecting seat, and the two sets of connecting seats are fixedly connected by providing a docking buckle.

[0010] Optionally, the trapezoidal module is made by secondary casting of a shaping template.

[0011] Optionally, the middle grid of the hollow beam frame wraps around the trapezoidal modules and does not contact the trapezoidal modules.

[0012] Optionally, the docking buckle includes: a control panel, the number of control panels is set to two groups, a reinforcing edge strip is integrally provided on the outside of the control panel, the two groups of control panels are hingedly connected, and a locking screw is provided on the outside of one side of the control panel through a threaded connection.

[0013] The beneficial effects are as follows: 1. The main floor slab and the hollow beam frame together constitute the floor slab structure. The hollow beam frame can absorb shock, and the gap shock absorption effect is no longer used alone, which ensures the strength of the floor slab. The upper and lower trapezoidal modules can fit stably and provide support functions. When the upper and lower trapezoidal modules fit together, the sides of the trapezoidal modules also present staggered slopes. A small amount of concrete pouring can be used to fix the trapezoidal modules, and then the two sets of main floor slabs can be fixed to form a stable floor slab. The assembly can be completed by only a small amount of pouring, which does not affect transportation and is convenient for production.

[0014] 2. The interior of the hollow beam can be filled with water for circulation, and the heater and drive assembly are connected in series, so it can be used as floor heating. A circulation channel is formed by the guide edge, which facilitates the interconnection between the groups of hollow beams. If the steel hose and the hollow beam are selectively filled with circulating water and heated, it can be used as floor heating. There is no need to lay additional floor heating space, making the living environment more suitable.

[0015] 3. The internal space of the hollow beam frame has dual uses. If air conditioning or air heating is installed indoors and floor heating is not needed, the hollow beam frame can be evacuated. First, the water in the hollow beam frame is pumped out, and then the air in the hollow beam frame is pumped out to form a negative pressure space. The edges of the ground and the joints between the wall panels and the ground are all hollow beam frames, which can slow down the temperature transmission and provide insulation effect.

[0020] The length and width of the upper base of the trapezoidal module 102 are smaller than the length and width of the lower base.

[0021] Among them, a dovetail groove 202 for assembly connection is opened in the middle of the side of the hollow beam frame 2, and two groups of hollow beam frames 2 can be fixedly connected by setting a splicing block that matches the dovetail groove 202.

[0022] The middle of the hollow beam frame 2 is a comb-shaped structure, the interior of the hollow beam frame 2 is a hollow structure, and a guide edge 203 is integrally provided inside the hollow beam frame 2 . The hollow beam frame 2 forms a uniform circulation channel through the guide edge 203 .

[0023] Among them, a steel wire hose 204 is connected in the middle of both sides of the hollow beam frame 2, and a connecting seat 205 is fixedly provided at the end of the steel wire hose 204. The outside of the connecting seat 205 is integrally provided with a flange structure, and the two groups of connecting seats 205 are fixedly connected by setting a docking buckle 3.

[0024] The trapezoidal module 102 is made by secondary casting of a shaping template.

[0025] The middle grid of the hollow beam frame 2 wraps around the trapezoidal module 102 and does not contact the trapezoidal module 102 .

[0026] Among them, the docking buckle 3 includes: a control panel 301, the number of control panels 301 is set to two groups, a reinforcing edge strip 302 is integrally arranged on the outside of the control panel 301, the two groups of control panels 301 are hingedly connected, and a locking screw 303 is arranged on the outside of one side of the control panel 301 through a threaded connection.

[0027] like Figure 1-8 As shown, the floor slab of this application is set by pouring three times, the specific steps are: The first pouring is carried out in the factory. First, the main floor slab 1 is prefabricated by a rectangular frame template. The steel beam frame 101 and the connected steel bar frame are placed in the frame template for prefabrication. The strength of the main floor slab 1 is ensured by the steel bar structure. Then, the main floor slab 1 is inverted for secondary pouring. The trapezoidal module 102 and the docking groove 103 are cast by the template. The steel beam frame 101 is wrapped by the trapezoidal module 102. At this time, the main floor slab 1 is formed as a whole, which is convenient for integrated stacking and palletizing, or transported by vehicle. After the main floor slab 1 is transported to the interior of the building, the third pouring is performed; The main floor slab 1 and the hollow beam frame 2 are transported to the interior of the building, and then the main floor slab 1 and the hollow beam frame 2 are assembled using the docking grooves 103 and docking pin piles 201 to form a whole floor slab. Then the floor slab is temporarily tied with ropes, and the gargle position of the hollow beam frame 2 is erected upward. Three pourings are performed between the hollow beam frame 2 and the trapezoidal module 102. Since the length and width of the upper bottom of the trapezoidal module 102 are lower than the length and width of the lower bottom, the sides of the trapezoidal module 102 are all inclined surfaces. When the upper and lower trapezoidal modules 102 are fitted together, the sides of the trapezoidal module 102 also present staggered inclined surfaces. The trapezoidal module 102 can be fixed by pouring a small amount of concrete, and then the two groups of main floor slabs 1 are fixed to form a stable floor slab. The hollow beam frame 2 will withstand the vibration, so there is no need to set up a separate anti-seismic gap.

[0028] Embodiment 2: Based on embodiment 1, Figure 6 As shown, the interior of the hollow beam 2 is a hollow structure, and a circulation channel is formed by the guide edge 203, so as to facilitate the interconnection between each group of hollow beams 2. Circulating water is filled and heated inside the steel wire hose 204 and the hollow beam 2, and can be used as floor heating without the need for additional floor heating space.

[0029] Embodiment 3: Based on embodiment 1, Figure 6 As shown, the air or water inside the hollow beam frame 2 can be pumped out by a pump, thereby reducing the thermal conductivity and providing a heat preservation function; the guide edge 203 also provides a supporting function, strengthens the strength of the hollow beam frame 2, and prevents the hollow beam frame 2 from collapsing when there is a negative pressure inside.

[0030] Specific usage and function of this embodiment: In the present invention, when in use, firstly, the main floor slab 1 is prefabricated by a rectangular frame template, and the steel beam frame 101 and the connected steel bar frame are placed in the frame template for prefabrication, and the strength of the main floor slab 1 is ensured by the steel bar structure, and then, the main floor slab 1 is inverted for secondary pouring, and the trapezoidal module 102 and the docking groove 103 are cast by the template, and the steel beam frame 101 is wrapped by the trapezoidal module 102; The main floor slab 1 and the hollow beam frame 2 are transported to the interior of the building, and then the main floor slab 1 and the hollow beam frame 2 are assembled using the docking groove 103 and the docking pin pile 201 to form a whole floor slab. The floor slab is temporarily tied with ropes, and then the floor slab is erected and poured three times between the hollow beam frame 2 and the trapezoidal module 102. A small amount of concrete is poured to fix the trapezoidal module 102, and then the two sets of main floor slabs 1 are fixed, and finally the binding is removed; The floor slab is laid on the ground by inserting the dovetail block into the dovetail groove 202, and then the floor slab is formed to provide the bearing function; When splicing the hollow beam frame 2, the connection seats 205 outside the two sets of hollow beam frames 2 are pre-assembled together, the ports outside the connection seats 205 are connected and sealed with sealing rings, and then the docking buckle 3 is installed, the locking screw 303 is tightened to open the two sets of control panels 301, and the connection seats 205 are buckled and assembled with two sets of reinforcing edge strips 302 to achieve fixation, and the sidemost set of steel wire hoses 204 are led to the room for retention; Filling the steel hose 204 and the hollow beam 2 with circulating water and heating them can be used as floor heating. Conversely, extracting the air or water in the hollow beam 2 can slow down the temperature propagation and provide a heat preservation effect.
