Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a support structure for filling gaps in composite slab formwork. Background Technology

[0002] With the development of modern industrial technology, prefabricated buildings have come into the public eye. Employing factory production and on-site assembly and installation, they represent modern industrialized production methods. Composite slabs are one type of prefabricated construction, with steel pipe truss prestressed concrete composite slabs being a typical example. After installation, a gap is reserved on the side of the beam (60mm) for later pouring, such as... Figure 5 As shown, the gap between the top surface of beam 60 and composite slab 70 is adjusted by filling the gap to correct the cumulative error during the installation of composite slab 70.

[0003] When constructing the gap-filling area along the edge of a prestressed concrete composite slab beam using a steel pipe truss, a 300-400mm wide strip formwork is required. During formwork erection, steel pipe uprights must be erected, and longitudinal and transverse horizontal bars, ground-level bars, and top-level bars must be installed to reinforce the uprights. Adjustable supports are then installed, followed by the laying of main steel pipes and secondary square timber, and finally, the wooden formwork. After the composite slab is installed, the adjustable supports need to be adjusted and reinforced. This traditional formwork erection method is cumbersome, resulting in low construction efficiency and wasting time and labor. Therefore, we propose a composite slab gap-filling formwork support structure to solve the aforementioned problems. Summary of the Invention

[0004] In view of this, in order to solve the problem that the traditional steel pipe truss prestressed concrete composite slab beam edge filling formwork erection process is relatively cumbersome, resulting in low construction efficiency and time and labor costs, this utility model provides a composite slab filling formwork support structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite slab filling template support structure, including a first reinforcing beam, including a vertical rod and a horizontal rod hinged to the top of the vertical rod, wherein an adjusting member is provided between the vertical rod and the horizontal rod for adjusting the rotation of the horizontal rod to improve the sealing of the filling area; The second reinforcing beam includes a horizontal section and a vertical section integrally set at one end of the horizontal section at a 90° angle. The horizontal section can be adjusted vertically and horizontally on the vertical rod through a positioning component, and the positioning component can be used to position the first and second reinforcing beams after adjustment. The vertical section is positioned and connected to the vertical rod through a connector, thereby completing the support of the entire template.

[0006] Furthermore, the positioning component includes an L-shaped block, the inside corner of which is snapped onto the bottom of the horizontal section and the side near the vertical rod, and the top of the L-shaped block cannot be higher than the top of the horizontal section, and the outside corner of the L-shaped block is in contact with the side of the vertical rod near the horizontal section.

[0007] Furthermore, the positioning component also includes a first screw fixedly connected to the side of the L-shaped block's external corner. A vertical adjustment hole is provided on one side of the vertical rod for adjusting the first screw to pass through. A first locking nut for fixing the vertical rod is threaded onto the first screw.

[0008] Furthermore, the positioning component also includes a second screw fixedly connected to the inside corner side of the L-shaped block, and a lateral adjustment hole for adjusting the second screw is provided on one side of the horizontal section, and a second locking nut for fixing the horizontal section is threaded on the second screw.

[0009] Furthermore, the connector includes a fixing block fixedly connected to one side of the vertical rod, and a tie rod passing through the fixing block and positioned and connected to the vertical section. A vertical hole is provided on one side of the vertical section for adjusting the position of the tie rod.

[0010] Furthermore, the adjusting component includes a rotating part and two adjusting screws that are threaded in opposite directions through both ends of the rotating part. The ends of the two adjusting screws that are far apart from each other are respectively hinged to the bottom of the crossbar and the top of the fixed block.

[0011] The embodiments of this utility model have the following beneficial effects: This invention effectively supports the entire formwork through the cooperation of positioning and connecting parts between the first and second reinforcing beams and the crossbars. It eliminates the need for erecting vertical poles, horizontal bars, and supports, simplifying the construction process, making operation more convenient, and thus improving construction efficiency. Furthermore, the vertical and horizontal adjustments between the first and second reinforcing beams allow for support of formwork with beams of different thicknesses and widths. The rotation adjustment of the crossbars via the adjusting parts increases the contact density between the wooden formwork and the composite slab in the gap-filling area, effectively ensuring the sealing and stability of the pouring.

Detailed Implementation

[0015] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0016] Example 1: Please refer to Figure 1 , Figure 5This embodiment provides a formwork support structure for filling gaps in composite slabs, including a first reinforcing beam 10. The first reinforcing beam 10 consists of a vertical rod 101 and a horizontal rod 102. The horizontal rod 102 is hinged to the top of the vertical rod 101, and the horizontal rod 102 is used to support the formwork in the gap between the beam 60 and the composite slab 70. The horizontal rod 102 can be rotated and adjusted by an adjusting member 50, which is located between the vertical rod 101 and the horizontal rod 102. By adjusting the adjusting member 50, the density between the wooden formwork 80 and the composite slab 70 can be increased through the horizontal rod 102, thereby improving the sealing and stability of the pouring.

[0017] The support structure also includes a second reinforcing beam 20, which is an integrally formed L-shape with a 90° turn. Specifically, it includes a horizontal section 201 and a vertical section 202. The horizontal section 201 can be adjusted vertically and horizontally on the vertical rod 101 via a positioning element 30. Adjusting the horizontal section 201 allows for the formwork fixing of beams 60 of different heights and thicknesses. Furthermore, after adjusting the second reinforcing beam 20, the first reinforcing beam 10 and the second reinforcing beam 20 can be positioned and fixed using the positioning element 30.

[0018] The support structure also includes a connector 40. After the first reinforcing beam 10 and the second reinforcing beam 20 are adjusted and positioned, the first reinforcing beam 10 and the second reinforcing beam 20 are finally connected and fixed through the connector 40, thereby completing the support and positioning of the entire template.

[0019] This invention can be used in the field of composite slab filling template support structure, and can also be applied to other fields of this invention.

[0020] Example 2: This example is a further improvement on the previous example: as follows Figures 1-5 As shown, the positioning component 30 includes an L-shaped block 301. The bottom surface of the inner corner of the L-shaped block 301 abuts against the bottom of the horizontal section 201, and the side surface of the inner corner of the L-shaped block 301 abuts against the side of the horizontal section 201 near the vertical rod 101, thereby causing the L-shaped block 301 to snap onto one bottom corner of the horizontal section 201. The horizontal section 201 can move back and forth within the inner corner of the L-shaped block 301 for adjustment. To ensure that the horizontal section 201 is supported and fixed to the square timber 90 at the bottom of the beam 60, the top of the L-shaped block 301 cannot be higher than the top of the horizontal section 201 to avoid contact with the square timber 90, which would prevent the horizontal section 201 from properly supporting the square timber 90. In addition, the side surface of the outer corner of the L-shaped block 301 contacts the side of the vertical rod 101 near the horizontal section 201, so that one side of the L-shaped block 301 abuts precisely between the horizontal section 201 and the vertical rod 101.

[0021] A first screw 302 is welded to the side of the external corner of the L-shaped block 301. A vertical adjustment hole 1011 is provided on one side of the vertical rod 101. One end of the first screw 302 passes through the vertical adjustment hole 1011 and extends outward. A first locking nut 304, which can be unscrewed, is threaded onto the extended end of the first screw 302. The vertical adjustment hole 1011 allows the first screw 302 to move synchronously up and down within the hole during the adjustment of the L-shaped block 301. After adjustment, the first locking nut 304 is tightened to fix the L-shaped block 301 onto the vertical rod 101. A first washer 303 is fitted onto the first screw 302 to improve the fixing effect.

[0022] A second screw 305 is welded to the side of the inner corner of the L-shaped block 301. A transverse adjustment hole 2011 is provided on one side of the horizontal section 201. One end of the second screw 305 passes through the transverse adjustment hole 2011 and extends outward. A second locking nut 307, which can be unscrewed, is threaded onto the extended end of the second screw 305. When adjusting the vertical movement of the second reinforcing beam 20, the second screw 305 can drive the L-shaped block 301 to move up and down synchronously, thereby driving the first screw 302 to move up and down within the vertical adjustment hole 1011. The transverse adjustment hole 2011 allows the second reinforcing beam 20 to be adjusted back and forth on the L-shaped block 301 when it is adjusted horizontally. Because the L-shaped block 301 is limited by the first screw 302 and the second screw 305 within the vertical adjustment hole 1011 and the transverse adjustment hole 2011 respectively, the L-shaped block 301 can only be adjusted vertically and cannot move horizontally with the second reinforcing beam 20. Therefore, by adjusting the vertical and horizontal movement of the second reinforcing beam 20, formwork can be provided for beams 60 of different heights and thicknesses. Finally, after adjusting the second reinforcing beam 20, the second locking nut 307 is tightened to fix the second reinforcing beam 20 to the L-shaped block 301, thus completing the support and fixation of the entire formwork. Similarly, to improve the fixing effect, a second washer 306 is added to the second screw 305.

[0023] Example 3: This example is a further improvement on the previous example: as follows Figures 1-3As shown, the connector 40 includes a fixing block 401 fixedly connected to one side of the vertical rod 101, and the fixing block 401 is positioned directly above the L-shaped block 301, so that the fixing block 401 corresponds to the vertical section 202 of the second reinforcing beam 20. A through hole 4011 is provided on one side of the fixing block 401 for the through-hole positioning of the tie rod 402. After the first reinforcing beam 10 and the second reinforcing beam 20 are adjusted and positioned, one end of the tie rod 402 is passed through the through hole 4011, and simultaneously through the wooden template 80 and the beam 60, and finally through the vertical section 202 of the second reinforcing beam 20, and then fixed with a washer and a nut. A vertical hole 2021 is provided on one side of the vertical section 202, and the positioning end of the tie rod 402 passes through the vertical hole 2021. After the second reinforcing beam 20 is vertically adjusted, it can be ensured that the tie rod 402 can always be aligned and pass through the vertical section 202, so as to achieve the fixation between the first reinforcing beam 10 and the second reinforcing beam 20. Since the fixing block 401 and the vertical section 202 are always aligned, during the horizontal adjustment process, as long as the length of the tie rod 402 is sufficient, the final fixation can be completed.

[0024] Example 4: This example is a further improvement on the previous example: as follows Figures 1-3 As shown, the adjusting component 50 includes a rotating part 501, which is U-shaped and used for the operation of the entire adjusting component 50. Each of the two ends of the rotating part 501, which are far apart from each other, is threadedly connected to an adjusting screw 502, with the threads of the two adjusting screws 502 arranged in opposite directions. The ends of the two adjusting screws 502, which are close together, extend to the inside of the rotating part 501, and the ends of the two adjusting screws 502, which are far apart from each other, are hinged to the bottom of the crossbar 102 and the top of the fixing block 401, respectively. After the first reinforcing beam 10 is placed on the upper square timber 90, the rotation of the rotating part 501 can drive the two adjusting screws 502 to move relative to each other, that is, to move closer to each other or further away from each other. Since the vertical rod 101 is in contact with the side square timber 90, it drives the horizontal rod 102 to flip upward. At the same time, the corresponding square timber 90 makes the wooden formwork 80 tightly contact the bottom of the composite plate 70, thereby increasing the compactness between the wooden formwork 80 and the composite plate 70 and avoiding grout leakage during the pouring process.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
