At this time, lattice columns are generally used instead.

[0003] There are many deficiencies and problems in the traditional lattice column assembly scheme: due to the large length of the lattice column, when the steel plates (or steel components that serve as connections) are welded in sequence along its length, the unwelded end may have excessive freedom, requiring repeated adjustment and positioning. The welded end may also experience stress concentration problems during the above adjustment and positioning process. In addition, due to the limitations of experience and skills, the assembly accuracy and efficiency of the lattice column are relatively low. Summary of the invention

The second locking piece is a high-strength bolt with a screw portion passing through the second straight slot, and the limiting vertical plate is provided with a second screw hole adapted to the second locking piece.

[0014] Furthermore, the telescopic rod includes a middle rod and end rods located at both ends thereof, the end rods extend in the same direction as the middle rod and are slidably connected, and can be fixed by a locking member or threadedly fastened.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0034] Reference Figure 1-6 The present embodiment provides a frame for assembling lattice columns and a method for using the frame, the frame comprising: a base 1, a limiting vertical plate 2, a horizontal supporting plate 3 and a telescopic rod 4, at least two sets of limiting vertical plates 2 are arranged opposite to each other on the base 1, the two sets of limiting vertical plates 2 arranged opposite to each other are movably connected to the base 1 and the spacing is adjustable; the horizontal supporting plate 3 is located between the two sets of limiting vertical plates 2 arranged opposite to each other, and is used to support the lattice column component 15; the telescopic rod 4 is located between the two sets of limiting vertical plates 2 arranged opposite to each other, and is used to press the lattice column component 15 against the limiting vertical plates 2.

[0035] When the lattice columns to be assembled are single-body lattice columns, the lattice column components 15 are steel plates and angle steels in single-body lattice columns; when the lattice columns to be assembled are composite lattice columns, the lattice column components 15 are single-body lattice columns.

[0036] Taking the assembly of a single lattice column as an example, during assembly: two groups of angle steels are placed on the horizontal support plate 3 in opposite directions, the horizontal plate of the angle steel is overlapped with the horizontal support plate 3, and the vertical plate of the angle steel droops naturally; then the limiting vertical plate 2 is moved so that the spacing between the two groups of limiting vertical plates 2 is equal to the side length of the single lattice column; the length of the telescopic rod 4 is adjusted so that the telescopic rod 4 is pressed against the facing surfaces of the vertical plates of the two groups of angle steels, and at the same time, the separated surfaces of the vertical plates of the two groups of angle steels are pressed against the limiting vertical plates 2 on both sides respectively; finally, the steel plate used to connect the angle steels is fixed. , placed on top of the angle steel cross plate, welded and fixed to construct a semi-finished product one with a U-shaped cross section (opening downward); after making two semi-finished products one, rotate the semi-finished product one 90° to make the cross section C-shaped, and the C-shaped openings are opposite to each other, and the top surfaces of the two semi-finished products one are welded and fixed with steel plates in the same manner as above to obtain a semi-finished product two; rotate the semi-finished product two 180°, and weld the steel plate on the top surface of the semi-finished product two at this time in the same manner as above to obtain a single lattice column.

[0037] In this embodiment, the base 1 can be configured as a plate or a rod according to working conditions. The plate can be a large one-piece plate that meets the requirements of stable support, or it can be configured as a plurality of parallel arrangements according to specific needs, just like the rod. Of course, an elevated foot 14 can also be provided at the bottom of the base 1 to adapt to different construction personnel and construction conditions. The elevated foot 14 can be a detachable and replaceable (for example, bolted) and fixed-length elevated foot, or it can be a retractable elevated foot with a locking function (for example, a threaded sleeve, etc.).

[0038] Since the cross section of the limiting vertical plate 2 is narrow, in order to ensure its support stability, in this embodiment, triangular support frames 5 are respectively provided on the separated sides of the two sets of relatively positioned limiting vertical plates 2. The triangular support frames 5 are slidably arranged on the base 1 and can be fixed by a locking member 8. The structure of the triangular support frame 5 can be set according to the actual working conditions. It can be a three-dimensional grid frame or a plane grid frame whose front projection of the external contour is a right-angled triangle. There can be a number of staggered horizontal braces, vertical braces, and diagonal braces inside. One right-angled side (or face) of the triangular support frame 5 is horizontal, and the other right-angled side (or face) is vertical and pressed against the limiting vertical plate 2. The main function of the triangular support frame 5 is to provide stable support for the limiting vertical plate 2. The side or face connected to the limiting vertical plate 2 can be welded, bolted, or other ways, which are not specifically limited here.

[0039] The connection mode between the triangular support frame 5 and the base 1 can be configured according to the actual working conditions. For example, a straight notch 6 can be provided at the bottom of the triangular support frame 5, and the straight notch 6 extends along the connecting direction of the two sets of relative position limiting vertical plates 2. The locking member 8 is configured as a high-strength bolt whose screw portion passes through the straight notch 6, and the base 1 is provided with a screw hole 7 adapted to the locking member 8. When it is necessary to change the spacing between the two sets of relative position limiting vertical plates 2, the locking member 8 is loosened, and the cap end of the locking member 8 loses the pressing force against the outer wall of the straight notch 6, and the triangular support frame 5 and the limiting vertical plate 2 can be slid along the extending direction of the straight notch 6; when the spacing is adjusted to be appropriate, the locking member 8 is tightened, and the cap end of the locking member 8 presses against the outer wall of the straight notch 6, so that the triangular support frame 5 cannot slide freely.

[0040] If the vertical end of the lattice column member is to be able to droop freely, the transverse support plate 3 should be suspended. In order for the transverse support plate 3 to stably support the lattice column component 15, the transverse support plate 3 should be connected to the limiting vertical plates 2 at both ends thereof. However, the position of the limiting vertical plates 2 also needs to be adjustable, so at least one group of limiting vertical plates 2 is configured to be slidably connected to the transverse support plate 3 and can be fixed by the locking member 11. The shape of the transverse support plate 3 can be set according to the actual working conditions, and can be I-shaped, T-shaped, or π-shaped (the ends parallel to each other are straight, not curved). The two ends of the transverse support plate 3 in the first direction (such as the transverse part of the aforementioned shape) are connected to the side of the limiting vertical plates 2 to achieve a stable, suspended structure. The second direction (such as the vertical part of the aforementioned shape) is located between the two groups of limiting vertical plates 2 in opposite positions. The top surface is used to support the transverse end of the lattice column member, and the vertical end of the lattice column member is freely drooping and placed between the limiting vertical plates 2 and the transverse support plate 3.

[0041] Regarding the connection method between the horizontal support plate 3 and the limiting vertical plate 2, it can be constructed according to the actual working conditions. For example, a straight slot 29 can be provided on the horizontal support plate 3, and the straight slot 29 extends along the connecting direction of the two sets of relatively positioned limiting vertical plates 2. The locking member 211 is a high-strength bolt whose threaded portion passes through the straight slot 29, and the limiting vertical plate 2 is provided with a screw hole 210 adapted to the locking member 21. When it is necessary to change the spacing between the two sets of relatively positioned limiting vertical plates 2, both the locking piece 1 8 and the locking piece 2 11 are loosened, the cap end of the locking piece 1 8 loses the pressing force against the outer wall of the straight slot 1 6, and the cap end of the locking piece 2 11 loses the pressing force against the outer wall of the straight slot 2 9, and the triangular support frame 5 and the limiting vertical plate 2 can be slid along the extension direction of the straight slot 1 6 (in the same direction as the straight slot 2 9); when the spacing is adjusted to be appropriate, the locking piece 1 8 and the locking piece 2 11 are tightened (in no particular order), the cap end of the locking piece 1 8 presses against the outer wall of the straight slot 1 6, so that the triangular support frame 5 cannot slide freely, and the cap end of the locking piece 2 11 presses against the outer wall of the straight slot 2 9, so that the cross support plate 3 and the limiting vertical plate 2 cannot slide relative to each other.

[0042] The horizontal support plate 3 can be slidably connected to the limiting vertical plate 2 on one side only, and fixed to the limiting vertical plate 2 on the other side using common, one-to-one corresponding screw holes-bolts; it can also be slidably connected to the limiting vertical plates 2 on both sides, and no specific restrictions are made here.

[0043] In addition, the present embodiment also provides a solution for more quickly constructing two semi-finished products into a single lattice column: along the length direction of the single lattice column, a plurality of groups of limiting vertical plates 2 are arranged, the spacing between the limiting vertical plates 2 on the same side of the single lattice column is greater than the length of the steel plate used to connect the semi-finished product, the two semi-finished products are arranged opposite to each other up and down, the openings are opposite, the semi-finished product located at the bottom is placed on the base 1, and the semi-finished product located at the top is placed on the horizontal support plate 3; the triangular stabilizing frame is pushed to make the limiting vertical plates 2 on both sides of the semi-finished product close to each other until the spacing is equal to the side length of the single lattice column; then the length of the telescopic rod 4 is adjusted so that the telescopic rod 4 is pressed against the adjacent surfaces of the two vertical ends of the semi-finished product, and at the same time, the separated surfaces of the two vertical ends of the semi-finished product are pressed against the limiting vertical plates 2 on both sides, wherein the number of telescopic rods 4 is increased or decreased according to demand, and the upper and lower semi-finished products should be respectively provided with supporting telescopic rods 4; finally, the steel plate is welded to the upper and lower semi-finished products at the gap between the limiting vertical plates 2 on the same side of the single lattice column.

[0044] However, when adopting this efficient assembly solution, it should be noted that: according to the side length of the lattice column, a plurality of screw holes 10 of different heights need to be set on the limit vertical plate 2 to adjust the installation height of the cross support plate 3, so that the spacing between the two semi-finished products 1 meets the requirements.

[0045] The telescopic rod 4 can be constructed to include a middle rod 4-1 and end rods 4-2 at both ends thereof, the end rods 4-2 extending in the same direction as the middle rod 4-1 and being slidably connected (it can be a sliding sleeve connection, that is, one of the middle rod 4-1 and the end rod 4-2 is hollow inside to accommodate the other), and the fixing and locking method can be: a plurality of screw holes 12 are respectively arranged on the middle rod 4-1 and the end rod 4-2 along the axial direction, and locking members 3 13 are passed through the screw holes 12 corresponding to the positions on the middle rod 4-1 and the end rod 4-2. The locking members 3 13 can be high-strength bolts. By changing the passing position of the locking members 3 13, the length of the telescopic rod 4 can be changed; the fixing and locking method can also be: an external thread is arranged on one of the middle rod 4-1 and the end rod 4-2, and a thread is arranged on the other, the two threads are fastened, and the length of the telescopic rod 4 can be changed by rotation.

[0046] In addition, a pressure plate 4-3 may be provided at the separated ends of the two groups of end rods 4-2, and the size of the pressure plate 4-3 is larger than the cross-sectional size of the end rod 4-2, so as to increase the contact area with the lattice column component 15 and improve the support stability.

[0047] When assembling composite lattice columns, the cross support plate 3 can be configured into a π shape, and its two parallel ends can be respectively inserted into different single lattice columns, and steel plates or other connecting steel components can be welded between adjacent single lattice columns in the same manner as above.

[0048] Compared with the prior art, the beneficial effects of the present invention are: using the horizontal support plate 3 to hang the lattice column component 15, using the adjustable spacing vertical plate 2 to limit the spacing of the two groups of relative lattice column components 15 that have not been welded, using the telescopic rod 4 to press the lattice column component 15, so as to cooperate with the spacing vertical plate 2 to adjust the spacing of the lattice column component 15 at one time, and then welding the connecting steel plate, it can avoid the influence of accuracy and efficiency caused by repeatedly adjusting the spacing of the unwelded ends of the lattice column component 15 during construction; at the same time, the tire frame is a shaped component, and its hole type and orientation are pre-set, such as the direction and accuracy of the straight notch 1 6 and the straight notch 2 9. When adjusting, it is only necessary to loosen or tighten the locking piece 1 8, the locking piece 2 11, etc., and push the relevant components along the above-mentioned notch, and its adjustment accuracy is not affected by the experience and skills of the construction personnel. The tire frame can be used not only for assembling single lattice columns, but also for assembling multiple single lattice columns into composite lattice columns, and has strong practicality.

[0049] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
