Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an adjustable supporting device for bearing superimposed plates. Background Art

[0002] In order to adapt to the fast-paced demands of modern construction and building structures, the construction period is required to be shortened as much as possible. Therefore, as the demand arises, a large number of building structures have begun to use prefabricated parts in order to shorten the construction period.

[0003] Therefore, prefabricated structures and assembly construction technology have been increasingly used. The commonly used assembly structure construction is still in a relatively troublesome situation. A large number of assembly components are required to hoist the composite panels. Conventional columns are still needed to support the bottom of the composite panels, which makes the construction steps cumbersome. It is necessary to build a bracket and reinforce the bracket to stably support the composite panels. It is also necessary to keep the composite panels horizontal, which inevitably generates a large amount of measures costs. Moreover, this operation method is relatively cumbersome and fails to give full play to the advantages of the assembly structure. The building structure cannot be built directly by assembly. The operation is complicated and means an extension of the construction period. Such an assembly structure cannot shorten the construction period by a large amount. It is necessary to continuously build a support frame on the lower layer to support the upper composite panels. How to effectively reduce the measures cost of assembly construction has become the main problem in reducing the cost of assembly construction and shortening the construction period.

[0004] Based on this, the utility model designs an adjustable supporting device for carrying the superimposed plates to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an adjustable supporting device for carrying composite plates, which can reduce the complex structure of the composite plate support system, combine the characteristics of the engineering structure entity, and achieve the elimination of composite plate support columns through support node design, reduce construction steps, and only need to pre-embed locking screws and then adjust the height of the bracket so that the height of each bracket is consistent and in a horizontal installation state. The bracket can carry the rack rod and the composite plate through the rack rod, which is convenient for the real prefabricated construction of the building structure. The structure is more streamlined, and the time for erecting beam and slab components can be effectively reduced while reducing a large number of composite plate support systems, reducing the standard layer construction period and saving support construction operations and costs.

[0006] The utility model is implemented as follows: an adjustable supporting device for carrying a laminated plate, comprising:

[0007] Rack rods, brackets and locking screws;

[0008] The rack rod is a straight rod with flat top and bottom;

[0009] The locking screw is a straight rod covered with threads, the locking screw is horizontally embedded and solidified inside the wall, and both ends of the locking screw are horizontally extended outside the wall;

[0010] The bracket is an integral structure consisting of a limit block, a horizontal plate and a vertical plate. The edges of the horizontal plate and the vertical plate are spliced ​​together to form an angle steel structure. The horizontal plate and the vertical plate are flat plates perpendicular to each other. An adjustment hole is provided on the vertical plate. The limit block is vertically protruded on the outer top edge of the horizontal plate.

[0011] The vertical plate is installed on the locking screw rod in a vertically adjustable manner through the adjustment hole, and the inner side surface of the vertical plate is in contact with the side wall of the wall; the horizontal plate is supported at the bottom of the frame rod.

[0012] Furthermore, the rack rod is a square tube.

[0013] Furthermore, the top of the horizontal plate is horizontal, the inner side of the vertical plate is vertical, and the distance h between the top of the horizontal plate and the top of the wall is the same as the height of the rack;

[0014] The top width d of the transverse plate is greater than the horizontal width of the rack rod, and the difference does not exceed 1 mm.

[0015] Furthermore, a reinforcing rib is provided between the bottom of the horizontal plate and the outer side wall of the vertical plate, and the reinforcing rib is perpendicular to the plane where the horizontal plate and the vertical plate are located;

[0016] The limit blocks, transverse plates, vertical plates and reinforcing ribs are welded into an integral steel structure.

[0017] Furthermore, the adjustment hole is a waist-shaped hole for vertical adjustment, and the adjustment hole and the locking screw are locked by a bolt.

[0018] The beneficial effects of the utility model are as follows: 1. The locking screw of the device is directly embedded and cast in the wall, so the structural integrity is stronger and the supporting strength is higher. There is no need to drill holes in the wall later, so the structural integrity of the wall is not damaged, and the levelness of the locking screw is higher;

[0019] 2. Considering that the locking screw may be not level enough, this device is equipped with a bracket for compensatory adjustment, which can fine-tune the height and left-right balance of the bracket, so as to adjust the horizontality of the rack rod, thereby ensuring that the laminated board can maintain a horizontal state after installation;

[0020] 3. The device has a simple structure and does not require any additional drilling tools. Moreover, one person can complete the installation and construction of the device. It is easy to operate and has low requirements, which greatly saves time and shortens the construction period. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figures 1 to 4 As shown, the utility model provides an adjustable supporting device for carrying composite plates. In order to better understand the above technical solution, the above technical solution will be described in detail below in combination with the drawings in the specification and specific implementation methods.

[0029] In a specific embodiment of the technical solution of the utility model:

[0030] It includes a rack rod 1, a bracket 2 and a locking screw 4;

[0031] The rack rod 1 is a straight rod with flat top and bottom; the rack rod 1 is a stainless steel square tube. It has high support strength and high flatness, and can also provide multiple supports with balanced forces from four directions. It can not only form a limit between the limit block 21 and the wall through the vertical side walls on both sides of the outside to stabilize the rack installation, but also provide load-bearing support through the bottom horizontal plate 24 and the bottom of the composite plate 31. It has high structural strength and can be placed on the bracket 2 during installation. The dimensions of the four sides are the same, which is more convenient to place.

[0032] The locking screw 4 is a straight rod covered with threads. The locking screw 4 is horizontally embedded and solidified inside the wall 3, and both ends of the locking screw 4 extend horizontally outside the wall 3.

[0033] The bracket 2 is an integral structure composed of a limit block 21, a horizontal plate 24 and a vertical plate 25. The edges of the horizontal plate 24 and the vertical plate 25 are spliced ​​together to form an angle steel structure, and the horizontal plate 24 and the vertical plate 25 are mutually perpendicular flat plates. The top of the horizontal plate 24 is horizontal, the inner side of the vertical plate 25 is vertical, and the distance h between the top of the horizontal plate 24 and the top of the wall 3 is the same as the height of the rack 1; the width d of the top of the horizontal plate 24 is greater than the horizontal width of the rack 1, and the difference does not exceed 1mm, so that the width of the top of the horizontal plate 24 that supports the rack 1 is accurate, which is convenient for the stable placement of the rack 1. As long as the size of the rack 1 is accurate, the installation of the device is stable, and the bearing height of the composite plate 31 is also more accurate.

[0034] A reinforcing rib 22 is provided between the bottom of the horizontal plate 24 and the outer side wall of the vertical plate 25, and the reinforcing rib 22 is perpendicular to the plane where the horizontal plate 24 and the vertical plate 25 are located;

[0035] The limit block 21 , the horizontal plate 24 , the vertical plate 25 and the reinforcing ribs 22 are welded into an integral steel structure, which has high structural strength and stable support, and can effectively and stably support the composite plate 31 .

[0036] An adjustment hole 23 is provided on the vertical plate 25. The adjustment hole 23 is a waist-shaped hole for vertical adjustment, and the adjustment hole 23 and the locking screw 4 are locked by bolts. The locking screw 4 is pre-buried in the wall 3, and the horizontal spacing between adjacent locking screws 4 does not exceed the length of a rack rod 1. The device does not require too many support points, and is more convenient to install. It only needs to calculate the combined load of the composite plate and the construction load, and does not require too many support points. The setting of the span of the square steel span plate is conducive to the horizontal control of adjacent composite plates.

[0037] The limit block 21 vertically protrudes on the outer top edge of the horizontal plate 24;

[0038] The vertical plate 25 is installed on the locking screw 4 in a vertically adjustable manner through the adjustment hole 23 , and the inner side surface of the vertical plate 25 is in contact with the side wall of the wall 1 ; the horizontal plate 24 is supported at the bottom of the rack rod 1 .

[0039] It should be noted that:

[0040] 1. The locking screw of the device is pre-buried and fixed when the wall is poured 3. The operation is simple. It only needs to prevent fixing when the wall is built. The level of the locking screw 4 can be kept as level as possible by using a level meter. There is no need to drill holes at all, and the integrity is stronger. The construction method of measuring and drilling holes in the later stage not only destroys the structure of the wall 3, but also causes a lot of dust on the construction site, which has an adverse effect on the health of personnel. At the same time, because there are no wires when the building structure is initially built, drilling requires drilling tools and power supplies. The construction steps of drilling holes in the later stage require dragging generators and drilling tools, which are cumbersome to operate. The device eliminates these steps and makes the structure of the wall 3 more complete. The locking screw 4 is pre-buried after measurement by a level meter, and the horizontality of the locking screw 4 is higher, and it can ensure that each locking screw 3 is supported on the steel bars inside the wall 3 to form an effective support. The screws drilled in the wall 3 in the later stage are generally unstable in the direction of artificial force, causing one side of the hole to tilt. This is already a common problem in on-site construction. The device does not have these drilling problems;

[0041] 2. There are also some straight rods or channel steels that are directly locked on the wall 1 by drilling holes and inserting expansion screws. However, this method of locking the entire straight rod is difficult to adjust the position and is prone to deflection, especially when drilling holes. Even if the positioning is accurate, as long as one hole is not drilled accurately, the level of the entire bracket will be deflected. If the drill hole and screw in the middle are deflected, either the bolt cannot be locked in, or it cannot be effectively supported, and the locking effect cannot be achieved;

[0042] 3. The existing rack 1 requires multiple people to support the rack 1 and drill holes to lock it with expansion bolts. Even a crane is needed to keep the rack 1 stable. Some racks even need two cranes to hoist the left and right sides of the rack 1 to ensure horizontal stability. The present device does not require any of these. Only one person is needed to install the bracket 2, and then one person can place the rack 1 between the limit block 21 and the wall 1. The operation is simple.

[0043] For the convenience of description, the inner and outer sides of the device are referred to as the side close to the wall as the inner side and the side extending outward as the outer side.

[0044] When the utility model is in use, the locking screw rod 4 is pre-buried by a level meter to keep it as horizontal as possible, and the horizontal degree of this pre-buried method is easier to control.

[0045] When installing the bracket 2 later, it is necessary to use a spirit level to calibrate the horizontal line of the installation height, and then put the adjustment hole 23 on the locking screw 4 and lock it with a nut. The adjustment hole 23 is a waist-shaped hole, which can vertically adjust the height position of the bracket 2 to ensure that the horizontal plate 24 is in a horizontal state. Since the rack rod 1 and the bracket 2 are mounted separately, even if the vertical plate 25 is not completely attached to the wall due to insufficient flatness of the cast structure, it will not affect the installation of the rod 1. The installation of the rod 1 has a higher fault tolerance rate and is more convenient.

[0046] After the bracket 2 is locked, the rack rods 1 are placed to ensure stable placement, and each rack rod 1 needs to be placed at a position that ensures that the bracket 2 can be evenly supported. Then the composite plate 31 can be hoisted for installation and construction.

[0047] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
