Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plate strip template reinforcement, in particular to a reinforcement device for a laminated plate strip. Background Art
[0002] With China vigorously promoting prefabricated structural construction, composite slab construction is essential, involving both rigid assembly and pre-assembled slab strips. The space between the composite slabs (precast panels) is called a slab strip. After the slab strips require slab formwork for support, concrete is poured into the slab strips to securely connect them to the cast-in-place slab above the composite slab. The slab strip formwork is removed after the concrete sets and hardens.
[0003] If the treatment measures for the reserved slab assembly points are not properly taken, it will cause quality problems in the later decoration, which will require more manpower and money to deal with. The existing slab reinforcement method is generally fixed by the bottom return steel pipe support. This method has a cumbersome construction process, a relatively long erection time, and is difficult to operate. It consumes a lot of materials and labor. In addition, when using steel pipe formwork for erection, a large amount of materials are occupied. It is necessary to provide fixed-length steel pipes and wooden squares of appropriate length to adapt to the erection height and width of the slab position, which increases construction costs and cannot ensure the quality of reinforcement. In addition, when using steel pipe formwork for erection, workers' erection operations are not uniform, and the reinforcement return is not in place or over the top, which easily causes openings in the joints. In addition, the stability of the frame is greatly affected by human factors, and the workers' ability level directly affects the slab forming effect.
[0004] In addition to using bottom-supported steel pipes, the current method also uses aluminum membranes with independent supports. This method uses a single vertical pole for support, which can easily cause grout leakage on both sides and formwork misalignment. Both methods suffer from insecure reinforcement and loose joints, which can easily cause grout leakage during concrete vibration and affect the overall visual quality. Utility Model Content
[0005] In view of this, the utility model provides a reinforcement device for composite plate strips, which can reinforce and fix the plate strip templates of composite plates with different plate thicknesses, ensure the quality of the joints, and is firmly installed and easy to assemble and disassemble.
[0006] The utility model is realized through the following technical solutions: a reinforcement device for a composite plate strip, comprising a plate strip template and a fixing assembly; the plate strip template is the same length as the plate strip, the plate strip template width is greater than the plate strip width, the plate strip template is located at the bottom of the plate strip, and the two sides of the plate strip template are respectively abutted against the composite plates on both sides of the plate strip; the fixing assembly comprises a fixing rod, a screw rod and an adjusting assembly; the fixing rod is parallel to the connecting direction between the composite plates, and the two ends of the fixing rod are respectively overlapped on the top of the composite plates on both sides of the plate strip; the upper end of the screw rod is vertically fixed to the middle of the fixing rod, and the lower end of the screw rod extends through the middle of the plate strip template, and the distance between the screw rod and the composite plates on both sides of the plate strip is the same; the adjusting assembly is arranged on the protruding part of the screw rod, and the adjusting assembly can move along the length direction of the screw rod, and the adjusting assembly presses the plate strip template onto the bottom surface of the composite plate through a fastener that cooperates with the screw.
[0007] Furthermore, the adjustment component includes a butterfly card and a steel pipe. The steel pipe is parallel to the fixing rod and abuts against the plate and strip template. The two steel pipes are respectively limited in the two card slots of the butterfly card.
[0008] Furthermore, the width of the overlapped portion on each side of the plate strip formwork is not less than 5 cm; the length of the overlapped portion on each side of the fixing rod is not less than 10 cm; and the difference between the length of the steel pipe and the width of the plate strip is not less than 20 cm.
[0009] Furthermore, the fixing rod is made of a steel bar with a diameter of 18 mm.
[0010] Furthermore, multiple groups of fixing components are evenly arranged along the length direction of the plate strip.
[0011] Compared with the existing technology, the beneficial effects of the utility model are:
[0012] 1. The utility model can reinforce and fix the plate strip templates of composite plates with different plate thicknesses, and can accurately fix them in the plate strip position, effectively meeting the requirements of tight joints at the plate strip position and no leakage of slurry and expansion of the mold, and the components can be used in a turnover manner and are easy to dismantle.
[0013] 2. The utility model adopts elastic-plastic materials such as square steel bars, screws, and steel pipes as the main load-bearing components, which are easy to obtain and meet the load-bearing and use requirements of the fixed plate and strip formwork.
[0014] 3. The utility model can be transformed and used as a tool, has a wide adaptability, reduces construction costs, and reduces uncontrollable factors such as the arbitrariness of manual construction and erection standards that do not meet the requirements of the plan.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0020] The utility model provides a reinforcement device for laminated plate strips, such as Figure 1 、 2 As shown, the device includes a plate strip template 6 and a fixing assembly; the plate strip template 6 is the same length as the plate strip 9, and the width of the plate strip template 6 is greater than the width of the plate strip 9, and the width of the plate strip 9 is the distance between the connecting lines of the composite plates 7 on both sides of the plate strip 9; the plate strip template 6 is located at the bottom of the plate strip 9, and the two sides of the plate strip template 6 are respectively abutted against the composite plates 7 on both sides of the plate strip 9; the fixing assembly includes a fixing rod 1, a screw rod 2 and an adjusting assembly; the fixing rod 1 is parallel to the connecting line direction of the composite plates 7, and the two ends of the fixing rod 1 are respectively overlapped on the top of the composite plates 7 on both sides of the plate strip 9; the upper end of the screw rod 2 is vertically fixed to the middle of the fixing rod 1, and the lower end of the screw rod 2 extends through the middle of the plate strip template 6, and the distance between the screw 2 and the composite plates 7 on both sides of the plate strip 9 is the same; the adjusting assembly is arranged at the protruding part of the screw rod 2, and the adjusting assembly can move along the length direction of the screw 2, and the adjusting assembly presses the plate strip template 6 onto the bottom surface of the composite plate 7 through a fastener that cooperates with the screw 2.
[0021] The adjustment assembly includes a butterfly card 4 and a steel pipe 3. The steel pipe 3 is parallel to the fixing rod 1 and abuts against the plate and strip template 6. The two steel pipes 3 are respectively limited in the two card slots of the butterfly card 4.
[0022] In this embodiment, the fixing rod 1 is made of steel bars with a diameter of 18 mm. The screw rod 2 has a diameter of 14 mm, the steel pipe 3 has a diameter of 48 mm, and the fastener is a nut 5 that matches the screw rod 2. Leftover 18 mm steel bars processed at the construction site can be directly cut into straight sticks that are at least 20 cm longer than the width of the slab 9 to serve as the fixing rod 1. The overlapping portion of the fixing rod 1 on each side is no less than 10 cm long. The 14 mm diameter screw rod 2 is cut into an appropriate length according to the thickness of the building structure floor slab and fixed to the steel bars by welding to ensure a full weld. A hole can be perforated at the corresponding position in the middle of the slab template 6 to facilitate the insertion of the screw rod 2. The screw rod 2 passes through the slab template 6 and the position of the slab template 6 is adjusted to ensure that the distance between the screw rod 2 and the composite plates 7 on both sides of the slab 9 is the same. At the same time, the width of the abutment portion of the slab template 6 and the composite plates 7 on both sides of the slab 9 is consistent (width refers to the length of the abutment portion in the direction connecting the composite plates 7). Furthermore, the width of the abutment portion of the slab template 6 on each side is no less than 5 cm. From the bottom of the screw rod 2, screw the butterfly clamp 4 and nut 5 onto the screw rod 2. Adjust the position of the butterfly clamp 4 so that the steel pipe 3, which is restrained in the butterfly clamp slot, abuts the slab formwork 6. Furthermore, the difference between the length of the steel pipe 3 and the width of the slab 9 is at least 20 cm, that is, the length of each end of the steel pipe 3 extending from the slab 9 is at least 10 cm. Tighten the nut 5 to secure the butterfly clamp 4 so that the steel pipe 3 presses against the slab formwork, ensuring that there is no gap at the abutment between the slab formwork 6 and the composite plate 7, and preventing leakage and misalignment during the construction of the cast-in-place slab 8.
[0023] Multiple sets of fixing components can be evenly spaced along the length of the slab 9 to ensure the complete fixation of the slab formwork 6. Once the device is installed, the nut 5 controls the free movement of the steel pipe 3 on the slab formwork 6, ensuring that the device can adapt to different plate thicknesses and slab formwork materials. Tightening the nut 5 also increases the friction between the steel bar and the composite plate, firmly securing the entire reinforcement device to the composite plate 7. The flatness of the slab formwork 9 can also be adjusted by adjusting the position of the steel pipe 3 and the tightness of the nut 5, achieving a leak-proof effect at the clamped joints.
[0024] After all installation is completed, fine-tune the installation quality and tighten the nut 5 a second time. During the concrete pouring process, check the tightness of the nut 5 to ensure that each set of fixing components can function and avoid quality and safety accidents. After the construction is completed, when removing the reinforcement device, first loosen the nut 5, remove the steel pipe 3, remove the nut 5 and the butterfly clamp 4, and install them for turnover use.
[0025] The utility model discloses a composite plate strip reinforcement device, which is light, concise, and easy to operate, reduces labor and material consumption, has low cost investment, and significantly reduces quality problems caused by the position of the plate strip formwork at the construction site. It has a good effect of safe and civilized construction, and is very economical, practical, and popularizable.
[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
