Description

Technical Field

[0001] This utility model relates to the field of floor slab casting technology, specifically to a reinforcing component for cast-in-place strips of composite slabs. Background Technology

[0002] Floor slab construction is a common part of building construction. In this process, a structural support layer is usually built first, supported by columns. Then, rectangular composite slabs are placed on top of the structural support layer at intervals. Next, a layer board is placed below the strip between two adjacent composite slabs, so that the two sides of the layer board are tightly attached to the bottom surface of the two adjacent composite slabs to form a casting groove. Concrete is then poured into the casting groove to form a cast-in-place slab strip. After the cast-in-place slab strip solidifies, it connects with the precast slabs on both sides to form a dense floor slab.

[0003] As can be seen from the above, the airtightness of the fit between the layer slab and the bottom surface of the composite slab, as well as the structural stability of their relative positions, are necessary conditions for the successful casting of the cast-in-place slab strip. During the casting process, the weight of the concrete applies pressure to the layer slab, which inevitably affects the airtightness and relative structural stability between the layer slab and the composite slab, resulting in poor appearance quality of the cast-in-place strip. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforcing component for cast-in-place strips of composite slabs, which can solve the problems of insufficient airtightness / structural stability between composite slabs and layers to support the weight of concrete, and poor appearance quality.

[0005] This utility model is achieved through the following technical solution:

[0006] A reinforcing member for cast-in-place strips of composite slabs includes an upper pressure beam, which is vertically connected to a screw rod, and the screw rod is screwed with a nut. Pressure rods are vertically provided at both ends of the upper pressure beam along its length, and the bottom ends of the two pressure rods are respectively used to press down on the edges of two adjacent composite slabs. A lower pressure beam is arranged parallel to the upper pressure beam directly below it, and the top surface of the lower pressure beam is used to press down on a layer plate, so that the sides of the layer plate are pressed tightly and sealed against the edges of two adjacent composite slabs. The lower pressure beam has a through hole and slides with the screw rod through the through hole. The nut is used to press down on the lower pressure beam.

[0007] Optionally, the top ends of both the screw and the pressure rod are connected to the bottom of the upper pressure beam, and both are located at the middle of the width direction of the upper pressure beam.

[0008] Optionally, the screw is located at the middle of the upper pressure beam along its length.

[0014] Optionally, the foam double-sided adhesive is disposed near the inner edge of the laminate.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] This utility model provides a reinforcing component for cast-in-place strips of composite slabs. An upper pressure beam is provided, with a pair of vertically mounted pressure rods at opposite ends of its length. These rods press down on the inner edges of two adjacent composite slabs. A lower pressure beam is then positioned directly below the upper beam, pressing down on the upper slabs to support them and provide upward pressure. A screw and nut are then installed, with the screw vertically connected to the upper pressure beam and a through hole formed in the lower pressure beam. The screw passes downward through the through hole, and the nut is screwed onto the screw, pressing down on the bottom of the lower pressure beam. This gradually clamps the lower and upper pressure beams together, thereby clamping the composite slabs and the upper slabs, effectively improving the sealing performance and relative structural stability between them.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0023] Example

[0024] Please refer to Figure 1 and Figure 2 This embodiment provides a reinforcement component for the cast-in-place strip of composite slabs, including an upper pressure beam 10, which is vertically connected to a screw rod 11, and the screw rod 11 is screwed with a nut 111. Pressure rods 12 are vertically provided at both ends of the upper pressure beam 10 along its length, and the bottom ends of the two pressure rods 12 are respectively used to press down on the edges of two adjacent composite slabs. The second component includes a lower pressure beam 20, which is parallel to and directly below the upper pressure beam 10. The top surface of the lower pressure beam 20 is used to press down on the layered slabs, so that the two sides of the layered slabs are pressed tightly and sealed to the edges of two adjacent composite slabs. The lower pressure beam 20 has a through hole, and slides with the screw rod 11 through the through hole. The nut 111 is used to press down on the lower pressure beam 20.

[0025] The reinforcement component for the cast-in-place strip of composite slabs provided in this embodiment is achieved by setting an upper pressure beam 10 with a pair of vertical pressure rods 12, with the pressure rods 12 located at both ends of the upper pressure beam 10 along its length. The two pressure rods 12 press down on the inner edges of two adjacent composite slabs. On this basis, a lower pressure beam 20 is set directly below the upper pressure beam 10, pressing down on the layer plates to support them and provide upward pressure. Furthermore, a screw 11 and a nut 111 are provided. The screw 11 is vertically connected to the upper pressure beam 10 and has a through hole in the lower pressure beam 20, allowing the screw 11 to pass downward through the through hole. The nut 111 is then screwed to the screw 11, pressing down on the bottom of the lower pressure beam 20, thereby gradually clamping the lower pressure beam 20 and the upper pressure beam 10, thus clamping the composite slabs and the layer plates, effectively improving the sealing performance and relative structural stability between them.

[0026] To prevent the upper pressure beam 10 from bearing torque due to unbalanced force, the top ends of the screw 11 and the pressure rod 12 are both connected to the bottom of the upper pressure beam 10, and both are located in the middle of the width direction of the upper pressure beam 10.

[0027] With the above arrangement, the screw 11 and the pressure rod 12 are vertically installed at the bottom of the upper pressure beam 10, and both are located in the middle of the width direction of the upper pressure beam 10. When the three are subjected to axial force, they only exert vertical upward pressure or downward tension on the middle of the width direction of the upper pressure beam 10, and will not exert upward pressure or downward tension on other positions in its width direction, so as to avoid uneven force in its width direction causing torsional force, thereby avoiding the upper pressure beam 10 from bearing unnecessary torque.

[0028] To further improve the overall stress balance of the reinforcing component, the screw 11 is located at the middle of the length direction of the upper pressure beam 10.

[0029] In order to disassemble the reinforcement component for recycling after the concrete has solidified, both the screw 11 and the pressure rod 12 are detachably fitted with sleeves 13 that slide on the same axis. The length of the sleeve 13 on the pressure rod 12 matches the length of the pressure rod 12, and the length of the sleeve 13 on the screw 11 is greater than the length of the sleeve 13 on the pressure rod 12.

[0030] With the above setup, after the concrete solidifies, the concrete connects to the outer wall of the sleeve 13, but the inner wall of the sleeve 13 still maintains a detachable sliding fit with the screw 11 and the pressure rod 12. At this time, it is only necessary to remove the nut 111, remove the pressure beam 20, and then pull up the pressure beam 10 to pull the screw 11 and the pressure rod 12 out of the sleeve 13.

[0031] In order to prevent the middle part of the lower pressure beam 20 from deforming under the pressure of the nut 111, which would cause the shelf to deform, wooden blocks 21 are vertically provided at both ends of the lower pressure beam 20 along its length, and the top surface of the wooden blocks 21 is used to press the shelf.

[0032] By setting it up as described above, the lower pressure beam 20 is separated from the shelf, and the shelf is pressed down only by the wooden block 21. This avoids the problem of the shelf being forced to deform when the middle part of the lower pressure beam 20 deforms under the pressure of the nut 111.

[0033] To prevent the pressure beam 20 from bearing torque due to unbalanced force, the bottom of the timber 21 is connected to the top of the pressure beam 20.

[0034] To prevent the pressure bar 12 and the timber 21 from being out of collinear in applying force, which would cause the laminated board and the plywood to bend and deform due to torsion, the timber 21 is positioned directly below the corresponding pressure bar 12.

[0035] In order to increase the contact area between the nut 111 and the lower pressure beam 20 and reduce the pressure between them, a washer 112 is sandwiched between the nut 111 and the lower pressure beam 20.

[0036] To further prevent concrete slurry from flowing out of the gap between the composite slab and the layer slab, the above-mentioned reinforcing components for the cast-in-place strip of the composite slab also include two foam double-sided adhesive strips 30, which are sandwiched between the composite slab and the layer slab.

[0037] To prevent concrete from being pressed into the gaps between the laminate and the composite slab through the thickness of the foam double-sided adhesive 30, the foam double-sided adhesive 30 is positioned close to the inner edge of the composite slab.

[0038] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
