Description

Support frame for racks

The present invention relates to a construction rack, and in particular to a supporting frame for the rack.

When pouring a high beam at a construction site, a conventional construction rack as shown in FIG. 12 and FIG. 13 is used. First, a bottom frame 91 is set up at the bottom for personnel to get on and off and as a bottom support structure. When a pouring formwork 97 is to be installed, a plurality of adjustment seats 911 are first set up at the top of the bottom frame 91. The plurality of adjustment seats 911 are arranged in multiple rows as shown in FIG. 13, and each row of adjustment seats 911 is arranged at intervals as shown in FIG. 12. A long strip of first steel 92 is fixed on each row of adjustment seats 911. Then, as shown in FIG. 13, a plurality of adjustment seats 911 are laid. Several second-type steels 93 are arranged so that each second-type steel 93 is placed across and fixed on a plurality of first-type steels 92. The first-type steels 92 and the second-type steels 93 are both H-shaped steels. Then, pedals 94 and angle bars 95 for construction workers to step on are staggered on the plurality of second-type steels 93. Adjustable steel pipe pillars 96 are fixed on the angle bars 95. The template 97 is provided with a plurality of grids 971 and a plurality of through-bars 972 for support on the back. The template 97 can be set up by fixing the plurality of through-bars 972 on the tops of the plurality of rows of adjustable steel pipe pillars 96.

However, the above-mentioned existing construction racks have the following disadvantages:

1. During installation, the first H-shaped steel 92 and the second H-shaped steel 93 need to be hoisted by a crane and raised to the top of the base frame 91. Since the first H-shaped steel 92 and the second H-shaped steel 93 have considerable weight, not only is the hoisting operation highly dangerous, but the construction workers need to assist in setting the above-mentioned H-shaped steel in the exact position at the top of the base frame 91, and there is also the risk of being hit or falling by the H-shaped steel.

2. Since the structural connection and support between the multiple adjustment seats 911 arranged in multiple rows and the multiple first-type steels 92 respectively arranged on the multiple rows of adjustment seats 911 are poor, during the pouring operation, if the external force caused by the concrete acts on part of the structure first, causing the load to be concentrated on part of the adjustment seats 911 and the first-type steels 92, the adjustment seats 911 and the first-type steels 92 may be deformed, causing the multiple second-type steels 93, pedals 94, and angle bars 95 laid above to tilt, causing construction workers to miss when they want to step on the pedals 94, or causing the adjustable steel pipe support 96 on the angle bars 95 to fail to provide good support, resulting in the template 97 bursting and other industrial safety accidents. The risk is higher.

In order to solve the problem that the existing construction racks are dangerous when hanging and installing steel sections, and the overall structural connectivity is poor and the support is weak, resulting in a higher risk of industrial accidents, the purpose of this invention is to propose a support frame for the rack that does not require the use of long steel sections, has strong structural connectivity, and can provide good and sufficient support.

The present invention solves the technical problem of a support frame for racking, which comprises: a plurality of support columns, which extend upright and are arranged at intervals; and a plurality of support units, each of which is arranged between two adjacent support columns, and the plurality of support units are arranged to form at least two rectangular structures, each of which is formed by four support units surrounding it, and any two adjacent rectangular structures share one of the support units; each of the support units The element comprises two structural square tubes, the two structural square tubes are parallel and are respectively a top square tube and a bottom square tube, the two ends of each structural square tube are respectively fixed on the two corresponding supporting columns, and each structural square tube is provided with a plurality of connecting lugs, the plurality of connecting lugs are paired, and the two connecting lugs in a pair are respectively located on the opposite sides of the structural square tube, and each connecting lug is provided with a connecting hole; and at least one connecting rod, the connecting rod connects the top square tube and the bottom square tube.

The supporting frame for racking, wherein each supporting unit comprises a plurality of connecting rods, some of which are perpendicular to the two structural square tubes, and the remaining connecting rods extend obliquely from the middle of the top square tube and connect to the bottom square tube near the two ends.

The support frame for the rack comprises a plurality of reinforcing rods, each of which is arranged between the top square tubes of the two parallel supporting units, and each of the two opposite ends of the reinforcing rod is fixed with a joint, and the joint and the connection hole of one of the connecting ears of the corresponding top square tube are penetrated by a pin, so that the reinforcing rod is fixed to the top square tubes of the two parallel supporting units.

The supporting frame for racking, wherein two reinforcing diagonal rods are provided between each of the structural square tubes and the corresponding two supporting columns, each of the reinforcing diagonal rods is fixed with a joint, and the joint and the connecting hole of one of the connecting lugs of the structural square tube are penetrated by a pin, so that the reinforcing diagonal rod is fixed to the structural square tube, and the two reinforcing diagonal rods extend obliquely from the middle position of the structural square tube and are respectively connected to the corresponding two supporting columns.

The supporting frame for the rack comprises a plurality of reinforcing rods, each of which is disposed between the top square tubes of the two parallel supporting units and fixed to the top square tubes of the two parallel supporting units.

The supporting frame for the rack, wherein each of the reinforcing rods is a round tube.

The supporting frame for racking, wherein each of the reinforcing rods comprises a square tube body and a plurality of pairs of ears, each pair of the ears is respectively arranged on two opposite sides of the square tube body, and each ear of each pair of the ears is provided with a connecting hole.

In order to understand the technical features and practical effects of the present invention in detail and to implement it according to the content of the invention, the preferred embodiment shown in the drawings is further described in detail as follows: As shown in Figures 1 and 2, the support frame for the rack of the preferred embodiment of the present invention is used in the rack for construction and is installed on a base frame 90 as a support structure of the middle section. The supporting frame includes a plurality of supporting columns 10 and a plurality of supporting units 20. The plurality of supporting columns 10 are respectively connected to the top ends of the plurality of columns of the base frame 90 and arranged at intervals. A supporting unit 20 is arranged between any two adjacent supporting columns 10, and the supporting unit 20 is fixed on the two adjacent supporting columns 10.

As shown in Figures 1 and 2, the plurality of support units 20 are arranged to form two rectangular structures, each of which is surrounded by four support units 20. The two rectangular structures are adjacent to each other and share one of the support units 20 to form a Japanese-shaped structure. Specifically, the support frame includes six support columns 10 and seven support units 20. The six support columns 10 are arranged in two rows, each row includes three support columns 10, and one of the support units 20 is used as a common side of the two rectangular structures. It forms one of the rectangular structures with the other three support units 20, and forms another rectangular structure with the remaining three support units 20.

As shown in FIG2 , each of the supporting units 20 includes two structural square tubes 21 and a plurality of connecting rods 22. The two structural square tubes 21 are parallel to each other in the vertical direction. Each of the structural square tubes 21 has a square tube structure, and the two ends of each of the structural square tubes 21 are respectively fixed on the two corresponding supporting columns 10. Each of the connecting rods 22 extends from one of the structural square tubes 21 to the other structural square tube 21 as a structure for strengthening support. As shown in FIG3 , specifically, the two structural square tubes 21 are respectively a top square tube 21A and a bottom square tube 21B. As shown in FIG4A , when fixed on the two corresponding supporting columns 10, the top square tube 21A is located above the bottom square tube 21B.

The two ends of the top square tube 21A and the bottom square tube 21B are fixed to the two corresponding support columns 10 by means of bolts. Specifically, as shown in FIG. 4A and FIG. 4B , the support column 10 includes a vertical tube 11 and at least two assembly disks 12 connected to the vertical tube 11. Each assembly disk 12 is provided with a plurality of plug holes 13 of different shapes and apertures. Taking the top square tube 21A as an example, a connector 70 is fixed to each end of the top square tube 21A. The connector 70 is a connector having a plurality of holes 13 of different shapes and apertures. 70 is a C-shaped connector and is provided with two pin holes 71 opposite to each other. The two pin holes 71 of the connector 70 and one of the corresponding sockets 13 of one of the assembly discs 12 are penetrated by a pin 80, so that the top square tube 21A is fixed to the two corresponding support columns 10, and the bottom square tube 21B is fixed in the same way; by fixing the connector 70 in a pin manner, the convenience of assembly and disassembly can be increased, and the efficiency of construction can be improved.

As shown in FIG. 3 , in a preferred embodiment of the present invention, the plurality of connecting rods 22 are respectively three straight connecting rods 22A and two oblique connecting rods 22B arranged in a staggered manner. The straight connecting rods 22A are perpendicular to the top square tube 21A and the bottom square tube 21B to increase the overall structural strength, while the two oblique connecting rods 22B extend obliquely from the middle position of the top square tube 21A and are respectively connected to the positions near the two ends of the oblique connecting rod 22B to disperse the external force on the top square tube 21A so that the supporting rod 21A can be easily connected to the bottom square tube 21B. The support unit 20 has better support and can bear a larger load. In the preferred embodiment of the present invention, the support unit 20 includes a plurality of connecting rods 22, which are three straight connecting rods 22A and two oblique connecting rods 22B. In other embodiments, the number and position of the straight connecting rods 22A and the oblique connecting rods 22B are not limited to the preferred embodiment of the present invention. As long as the support unit 20 includes at least one connecting rod 22, the effect of increasing the structural strength and improving the supporting force can be achieved.

As shown in FIG. 3, in a preferred embodiment of the present invention, each of the structural square tubes 21 further includes a tube body 210 and a plurality of connecting lugs 212. The plurality of connecting lugs 212 are arranged in pairs, and the two connecting lugs 212 are arranged on the left and right sides of the tube body 210, respectively. Specifically, the plurality of pairs of connecting lugs 212 are arranged at equal intervals, and the distance between any two pairs of adjacent connecting lugs 212 is 30 cm. Each connecting lug 212 is provided with a connecting hole 213, which can be connected to various reinforcing components as needed, further increasing the structural strength of the supporting frame and improving the load that the supporting frame can bear. The following is further explained with FIG. 5 to FIG. 7.

As shown in FIG. 5 , in order to increase the overall structural strength and supporting force of the support frame, the support frame may further include a plurality of reinforcing rods 30A, each of which is disposed between the top square tubes 21A of two parallel support units 20, and each of which has a connector 70 fixed to its two ends, and the two pin holes 71 of the connector 70 are connected to the corresponding top square tubes 21A. The connecting hole 213 of one of the connecting ears 212 is penetrated by a latch 80, and each of the reinforcing rods 30A is fixed to the top square tubes 21A of the two parallel supporting units 20 by the latch method, and the reinforcing rods 30A are connected between the top square tubes 21A of the two parallel supporting units 20, so as to further increase the structural strength of the overall supporting frame.

As shown in FIG. 6 , the support frame can be equipped with another type of reinforcing rod 30B in the same manner as the above-mentioned bolt fixing method. The difference between the two is that the reinforcing rod 30A shown in FIG. 5 is a round tube, while the reinforcing rod 30B shown in FIG. 6 includes a square tube body 31 and a plurality of ear pieces 32. The plurality of ear pieces 32 are paired, and the two paired ear pieces 32 are respectively arranged on opposite sides of the square tube body 31. The plurality of paired ear pieces 32 are arranged at equal intervals. Each ear piece 32 is provided with a connection hole. By adopting the same configuration as the structural square tube 21, the reinforcing rod 30B can be further connected to other reinforcing members through the connection hole of the ear piece 32. By matching the connecting ear pieces 212 of each structural square tube 21 with the ear pieces 32 of each reinforcing rod 30B, users can design different reinforcing member connection forms by themselves, and the structural strength and supporting force of the supporting frame are more diverse.

In addition, as shown in FIG. 7 , the support frame may be provided with two reinforcing diagonal rods 40 between the top square tube 21A and the two corresponding supporting columns 10, and each of the two ends of the reinforcing diagonal rods 40 is fixed with a joint 70, and the supporting column 10, in addition to the two assembly disks 12 respectively fixing the top square tube 21A and the bottom square tube 21B, further includes another assembly disk 12, and the two pin holes 71 of the joint 70 fixed to one end of the reinforcing diagonal rod 40 and the corresponding one of the pin holes 71 of the joint 70 are connected to the two ends of the reinforcing diagonal rods 40. One of the insertion holes 13 of the other assembly disk 12 of the supporting column 10 is penetrated by a latch 80, and the two pin holes 71 of the joint 70 fixed to the other end of the reinforcing inclined rod 40 and the connecting hole 213 of one of the connecting ear pieces 212 of the top square tube 21A are penetrated by a latch 80, so that the two reinforcing inclined rods 40 are fixed to the top square tube 21A and extend obliquely from the middle position of the top square tube 21A to be connected to the corresponding two supporting columns 10 respectively.

As shown in FIG. 7 , the support frame is also provided with two reinforcing diagonal rods 40 between the bottom square tube 21B and the two corresponding support columns 10, and the fixing method thereof is also fixed by the joint 70 and the latch 80 in a latching manner. The difference is that the two reinforcing diagonal rods 40 fixed to the bottom square tube 21B are not directly connected to the two corresponding support columns 10, but cooperate with the assembly disk 902 on the column of the base frame 90 on which the support frame is provided, and the support column 10 is upright and connected. The column of the base frame 90 is provided with a connecting disc 902 on the column and has the same structure as the connecting disc 12 on the supporting column 10. The two reinforcing diagonal rods 40 fixed to the bottom square tube 21B cooperate with the connecting disc 902 on the column of the base frame 90 provided with the corresponding two supporting columns 10, and are fixed by the joint 70 and the latch 80 in a latching manner, so that the two reinforcing diagonal rods 40 fixed to the bottom square tube 21B are indirectly connected to the corresponding two supporting columns 10.

By fixing the reinforcing diagonal rod 40 on the top square tube 21A and the bottom square tube 21B, and connecting the obliquely extended reinforcing diagonal rod 40 with the corresponding supporting column 10, the overall structural strength and supporting force of the supporting frame can be further increased, making the supporting frame less prone to deformation and having better supporting properties.

Through the above structure, when installing the support frame, the plurality of support units 20, the reinforcement rods 30A, 30B and the reinforcement diagonal rod 40 can be respectively transported to the top of the base frame 90, and then the support units 20, the reinforcement rods 30A, 30B and the reinforcement diagonal rod 40 are assembled and fixed through the joints 70 and the latches 80; the support frame does not use long strips of steel, but uses a plurality of components to assemble and form a support structure, which can save the work of hanging steel, thereby avoiding the risk of steel falling, injuring construction workers, causing construction workers to fall, and other accidents.

As shown in FIGS. 8 to 10, the support frame is used to install the formwork before pouring the crossbeam, wherein a plurality of pedals 94 and a plurality of angle bars 95 are staggered on the support frame. Specifically, the pedals 94 and the angle bars 95 span across the structural square tubes 21 of the two parallel support units 20. The pedals 94 and the angle bars 95 are connected to the support frame by the structural square tubes 21 having a square tube structure. The angle bar 95 is placed on the top surface of the structural square tube 21, which can increase the contact area, avoid the pedal 94 and the angle bar 95 from being placed incorrectly, which will have a negative impact on the safety and accuracy of the construction, and prevent the pedal 94 and the angle bar 95 from falling from the supporting frame; a number of adjustable steel pipe pillars 96 are fixed on each of the angle bars 95, and the template is fixed on the top of these adjustable steel pipe pillars 96.

During the installation of the formwork, grouting or other construction work, the weight of the construction workers stepping on the pedal 94 or the concrete poured into the formwork fixed to the top of the adjustable steel pipe support 96 causes the support frame to bear external force and generate load. At this time, the two structural square tubes 21 fixed to the support column 10, the connecting rod 22 between the two structural square tubes 21 and the support single The arrangement of the elements 20 to form a rectangular structure provides a support structure with strong structural connectivity and good support, which can effectively disperse the external force borne by the support frame, avoid the load of the support frame from being concentrated in a fixed position, and make the load more evenly distributed on the support frame, making the support frame less likely to deform, and can reduce the risk of the pedal 94 and the angle bar 95 tilting or even falling, and reduce the possibility of industrial safety accidents.

Among them, if the supporting frame is further equipped with the plurality of reinforcing rods 30A as shown in FIG5, the position where the adjustable steel pipe support 96 is fixed on the angle bar 95 can be supported by the reinforcing rods 30A as shown in FIG10, thereby further improving the supporting force of the supporting frame and making the load distribution of the supporting frame more uniform, further reducing the risk of template bursting during grouting; in addition, when in use, a guardrail 50 can be installed on the top of the plurality of supporting columns 10, and the guardrail 50 surrounds the area where the pedal 94 and the angle bar 95 are laid to prevent construction workers from falling from the racks on which the supporting frame is applied.

In the preferred embodiment of the present invention, the support frame includes six support columns 10 and seven support units 20 to form two rectangular structures. In other embodiments, the construction personnel can determine the number of support columns 10, support units 20 and the rectangular structures according to the size of the template to be installed and other engineering requirements. As long as the plurality of support units 20 are arranged to form at least two rectangular structures, and any two adjacent rectangular structures share one of the support units 20, the structure of the present invention can achieve strong connectivity and effectively disperse the external force.

The above is only the preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any person with ordinary knowledge in the relevant technical field, within the scope of the technical solution proposed by the present invention, can make partial changes or modifications to the technical content disclosed by the present invention, and within the scope of the technical solution of the present invention, and all of them are still within the scope of the technical solution of the present invention.
