Description

Technical Field

[0001] The utility model relates to the technical field of building construction auxiliary devices, in particular to a construction support device for a cast-in-situ belt of a composite slab. Background Art

[0002] As a prefabricated slab composed of concrete and steel bars, composite slabs are lightweight, high-strength, heat-insulating, sound-insulating, waterproof, and fire-resistant, and are widely used in construction and engineering. However, due to their own structural composition, composite slabs must rely on the support of other structures to withstand horizontal and vertical forces.

[0003] Due to the large volume of the composite slab, the general supporting structure has a small supporting range, and multiple supporting structures need to be installed to support the composite slab. This not only wastes a lot of material resources, but also makes the installation operation more cumbersome for the staff. For this reason, we proposed a construction support device for the cast-in-place strip of the composite slab to solve the above problems. Utility Model Content

[0004] The utility model solves the deficiencies of the prior art and provides a construction support device for cast-in-situ strips of composite slabs, which is convenient to shrink or expand, realizes multi-point support of the composite slabs, reduces the operation steps of the workers, and improves the installation efficiency.

[0005] To achieve the above-mentioned object, the present invention first proposes a construction support device for cast-in-situ strips of composite slabs, comprising a central support column and four auxiliary support columns arranged parallel to the central support column. The four auxiliary support columns are symmetrically arranged with the central support column as the center, and the auxiliary support columns are connected to the central support column via a scissor-type telescopic mechanism.

[0006] The scissor-type telescopic mechanism includes two fixed rods, and the opposite surfaces of the central support column and the auxiliary support column are respectively provided with a groove and a rectangular groove matching the size of the fixed rod. A slide rail is provided in the rectangular groove of the auxiliary support column along the length direction of the rectangular groove, and two sliders are slidably installed in the slide rail. The two fixed rods are parallel and cross-arranged, and one end of the two fixed rods is respectively hinged to the upper and lower ends of the groove of the central support column, and the other ends of the two fixed rods are respectively hinged to the two sliders of the auxiliary support column. The two fixed rods are correspondingly provided with a plurality of through holes arranged along the length direction as adjustment holes.

[0007] In this embodiment, the central support column and the auxiliary support column are both telescopic columns with adjustable heights.

[0008] In this embodiment, the central support column includes a telescopic rod, a square hole, a rotating block and a threaded lifting rod. A square hole coaxially arranged with the central support column is opened in the center of the upper end of the central support column. The middle part of the central support column is rotatably assembled with a rotating block at the bottom of the square hole. A threaded lifting rod is coaxially installed in the square hole. The bottom of the threaded lifting rod is fixed to the rotating block, so that the threaded lifting rod and the rotating block are linked. The telescopic rod matches the size of the inner cavity of the square hole. The telescopic rod is slidably installed inside the square hole, and the telescopic rod and the threaded lifting rod are threadedly connected. The top end of the telescopic rod extends out of the central support column and a mounting plate is fixed on it.

[0009] In this embodiment, a threaded hole is opened in the center of the upper end of each auxiliary support column, a threaded rod is threadedly connected inside the threaded hole, the top end of the threaded rod extends out of the central support column and a mounting block is rotatably assembled thereon.

[0010] In this embodiment, mounting holes are provided between the mounting plate and the mounting block to facilitate connection with the composite plate.

[0011] In this embodiment, a pull rod is provided on the outside of the auxiliary support column to facilitate the staff to exert force.

[0012] In this embodiment, anti-slip support seats are installed at the bottom of the central support column and the auxiliary support column.

[0013] With the above structure, the utility model has the following advantages:

[0014] 1. Through the combination of the central support column and the auxiliary support column, as well as the cross connection of the fixing rods, not only the conversion of the device between the storage state and the unfolded state is realized, but also the stability in the unfolded state is ensured, providing multi-point support for the composite board and ensuring the support of the composite board. At the same time, the two fixing rods not only connect the central support column and the auxiliary support column, but also form a triangular area, which enhances the support stability of the entire device and prevents the occurrence of tipping.

[0015] 2. Since both the central support column and the auxiliary support column are height-adjustable telescopic columns, workers can easily adjust the support height, thereby improving construction efficiency.

[0016] 3. A pull rod is provided on the outside of the auxiliary support column for the staff to exert their strength. The staff only needs to pull the auxiliary support column and fix the fixing rod to complete the installation, which reduces the operation steps and improves the installation efficiency.

[0017] In summary, this device enables each auxiliary support column to shrink or expand with the central support column as the center, thereby achieving multi-point support for the composite plate, reducing the operating steps of the staff and improving installation efficiency.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0027] Example 1:

[0028] like Figures 1 to 3As shown, a composite slab cast-in-situ strip construction support device includes a central support column 100 and four auxiliary support columns 102 arranged parallel to the central support column 100. The four auxiliary support columns 102 are symmetrically arranged with the central support column 100 as the center. The auxiliary support columns 102 are connected to the central support column 100 through a scissor-type telescopic mechanism. The scissor-type telescopic mechanism allows the auxiliary support columns 102 and the central support column 100 to have a stowed state and an extended state.

[0029] The scissor-type telescopic mechanism includes two fixed rods 104, and the opposite surfaces of the central support column 100 and the auxiliary support column 102 are respectively provided with a groove 101 and a rectangular groove 103 that match the size of the fixed rod 104, and a slide rail 105 is provided in the rectangular groove 103 of the auxiliary support column 102 along the length direction of the rectangular groove 103, and two sliders are slidably installed in the slide rail 105. The two fixed rods 104 are arranged in parallel and crosswise, and one end of the two fixed rods 104 is respectively hinged to the upper and lower ends of the groove 101 of the central support column 100, and the other ends of the two fixed rods 104 are respectively hinged to the two sliders of the slide rail 105 of the auxiliary support column 102. The two fixed rods 104 are provided with a plurality of through holes arranged along the length direction as adjustment holes (not shown in the figure). When in the unfolded state, the positions of the two fixed rods 104 are locked by pins, thereby improving the stability of the support; the scissor-type telescopic mechanism can not only connect the central support column 100 and the various auxiliary support columns 102, but also enhance the stability between the central support column 100 and the various auxiliary support columns 102. The height adjustment component can adjust the support height of the device, which is convenient for coping with the support of composite plates of different heights.

[0030] In the storage state, the auxiliary support column 102 is parallel to the central support column 100, so that the ends of the two fixing rods 104 sliding in the slide rail 105 are moved away from each other until the auxiliary support column 102 is tightly attached to the outside of the central support column 100. At this time, the two fixing rods 104 are stored in the groove 101 of the central support column 100, completing the storage of the entire device. This not only makes it easier to store the device, but also prevents sharp edges from causing injuries to workers when they are carrying it.

[0031] When in the unfolded state, the central support column 100 can be placed in the center of the composite board to provide central support for the composite board. Then, the staff will pull each auxiliary support column 102 to expand in all directions. During the unfolding process of each auxiliary support column 102, the two fixing rods 104 in the same rectangular groove 103 will abut against each other, so that the lower end of the composite board can be better supported at multiple points. Finally, the intersection of the two fixing rods 104 is fixed with a pin to prevent the auxiliary support column 102 from sliding.

[0032] In this embodiment, the design of the fixing rod 104 enables each auxiliary support column 102 to shrink or expand with the central support column 100 as the center, thereby achieving multi-point support for the composite plate, and also making it convenient for the staff to store the device. At the same time, it also makes it convenient for the staff to install the support device, reduces the staff's operating steps, and improves installation efficiency.

[0033] Example 2:

[0034] like Figure 1-6 As shown, based on the first embodiment, the central support column 100 and the auxiliary support column 102 are both telescopic columns with adjustable heights.

[0035] The central support column 100 includes a telescopic rod 200, a square hole 201, a rotating block 202 and a threaded lifting rod 203. A square hole 201 coaxially arranged with the central support column 100 is opened in the center of the upper end of the central support column 100. A rotating block 202 is rotatably assembled at the middle part of the central support column 100 and at the bottom of the square hole 201. A threaded lifting rod 203 is coaxially installed in the square hole 201. The bottom of the threaded lifting rod 203 is fixed to the rotating block 202, so that the threaded lifting rod 203 and the rotating block 202 are linked together. The telescopic rod 200 matches the inner cavity size of the square hole 201. The telescopic rod 200 is slidably installed inside the square hole 201, and the telescopic rod 200 is threadedly connected to the threaded lifting rod 203. The top end of the telescopic rod 200 extends out of the central support column 100 and a mounting plate 204 is fixed thereon; further, the rotating block 202 of the central support column 100 of this device can also be replaced by a rotating motor to achieve electric telescopic extension.

[0036] A threaded hole is provided in the center of the upper end of the auxiliary support column 102, and a threaded rod 205 is threadedly connected inside the threaded hole. The top end of the threaded rod 205 extends out of the central support column 100 and a mounting block 206 is rotatably fixed on it. A mounting hole is provided between the mounting plate 204 and each mounting block 206.

[0037] The mounting plate 204 is circular, and the mounting block 206 is a 1 / 4 ring. When in the storage state, the four mounting blocks 206 are enclosed on the outside of the mounting plate 204 to form a full ring, and the center hole formed after the enclosure matches the size of the mounting plate 204. This not only facilitates the storage of the mounting plate 204 and the mounting blocks 206, but also avoids injuries to workers during transportation.

[0038] like Figure 2 As shown, a pull rod 207 is provided on the outside of the auxiliary support column 102, and the staff can pull the pull rod 207 to more easily open the auxiliary support column 102.

[0039] Anti-slip support bases 208 are installed at the bottom of the central support column 100 and the auxiliary support column 102 .

[0040] In this embodiment, the upper and lower ends of the rotating block 202 are rotatably connected to the central support columns 100 on the upper and lower sides. By rotating the rotating block 202, the staff can drive the threaded lifting rod 203 to rotate. Since the telescopic rod 200 slides inside the square hole 201 and the telescopic rod 200 is threadedly connected to the threaded lifting rod 203, the threaded lifting rod 203 can drive the telescopic rod 200 to move up and down. At the same time, the staff can rotate each threaded rod 205 to adjust each mounting block 206 and the mounting plate 204 to be on the same horizontal plane, so that the support height can be adjusted.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
