[0029] Reference is made to the drawings Figures 1-6The embodiment provides a jig for assembling a lattice column, which comprises a base 1, limiting vertical plates 2, a horizontal supporting plate 3 and telescopic rods 4, at least two groups of the limiting vertical plates 2 are oppositely arranged on the base 1, and the two groups of the limiting vertical plates 2 are movably connected with the base 1 and the spacing is adjustable; the horizontal supporting plate 3 is located between the two groups of the limiting vertical plates 2 oppositely arranged and is used for supporting a lattice column component 15; and the telescopic rods 4 are located between the two groups of the limiting vertical plates 2 oppositely arranged and are used for abutting the lattice column component 15 against the limiting vertical plates 2.

[0030] When the lattice column to be assembled is a single lattice column, the lattice column component 15 is a steel plate and an angle steel in the single lattice column; when the lattice column to be assembled is a composite lattice column, the lattice column component 15 is a single lattice column.

[0031] Taking the assembly of a single lattice column as an example, when assembling, two groups of angle steels are oppositely arranged on the horizontal supporting plate 3, the horizontal plate of the angle steel is overlapped with the horizontal supporting plate 3, and the vertical plate of the angle steel naturally drops; then the limiting vertical plates 2 are moved, so that the spacing of the two groups of the 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 abuts against the opposite faces of the vertical plates of the two groups of the angle steels, and the opposite faces of the vertical plates of the two groups of the angle steels are respectively abutted against the limiting vertical plates 2 on the two sides; finally, the steel plate used for connecting the angle steels is arranged above the horizontal plate of the angle steel and is welded and fixed, so that a semi-finished product one with a U-shaped section (the opening downward) is formed; after two semi-finished products one are manufactured, the semi-finished products one are rotated by 90 degrees, so that the section is C-shaped and the openings of the C-shaped sections are opposite; in the same way as described above, the top faces of the two semi-finished products one are welded and fixed by the steel plate, so that a semi-finished product two is obtained; the semi-finished product two is rotated by 180 degrees, and in the same way as described above, the steel plate is welded on the top face of the semi-finished product two at this time, so that a single lattice column is obtained.

[0032] In the embodiment, the base 1 can be arranged as a plate or a rod according to the working condition requirement, the plate can be an integral large plate meeting the stable support requirement, or can be arranged as a plurality of parallel plates according to the specific requirement; of course, the heightening supporting legs 14 can be arranged at the bottom of the base 1 to adapt to different construction workers and construction working conditions, the heightening supporting legs 14 can be the heightening supporting legs with fixed length which can be detachably replaced (for example, bolt connection), or can be the telescopic heightening supporting legs with locking function (for example, threaded sleeve rod).

[0033] In order to ensure the stability of the support, the triangular support frame 5 is arranged on the side of the two groups of positionally opposite limiting vertical plates 2, and is slidably arranged on the base 1 and can be fixed by the locking member one 8. The structure of the triangular support frame 5 can be set according to the actual working condition, and can be a three-dimensional grid or a plane grid with the outer profile of the front view being a right triangle, and the inside can have several staggered horizontal supports, vertical supports and inclined supports, etc. One of the right angles (or surfaces) of the triangular support frame 5 is horizontal, and the other right angle (or surface) is vertical and abuts 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, and the edge or surface connected with the limiting vertical plate 2 can be welded, bolted or in several other ways, which is not limited here.

[0034] The connection mode of the triangular support frame 5 and the base 1 can be set according to the actual working condition. For example, a straight slot one 6 can be arranged at the bottom of the triangular support frame 5, the straight slot one 6 extends along the connecting line direction of the two groups of positionally opposite limiting vertical plates 2, the locking member one 8 is arranged as a high-strength bolt penetrating through the straight slot one 6, and the base 1 is provided with a screw hole one 7 matched with the locking member one 8. When the distance between the two groups of positionally opposite limiting vertical plates 2 needs to be changed, the locking member one 8 is loosened, the cap end of the locking member one 8 loses the abutting force against the outer wall of the straight slot one 6, and the triangular support frame 5 and the limiting vertical plate 2 can be slid along the extension direction of the straight slot one 6. When the distance is adjusted appropriately, the locking member one 8 is tightened, the cap end of the locking member one 8 abuts against the outer wall of the straight slot one 6, so that the triangular support frame 5 cannot be freely slid.

[0035] If the vertical end of the lattice column component can freely droop, the horizontal supporting plate 3 should be arranged in a suspended manner. In order to enable the horizontal supporting plate 3 to stably support the lattice column component 15, the horizontal supporting plate 3 should be connected with the limiting vertical plates 2 at both ends, but the position of the limiting vertical plate 2 also needs to be adjustable, so at least one group of limiting vertical plates 2 is slidably connected with the horizontal supporting plate 3 and can be fixed by the locking member two 11. The shape of the horizontal supporting plate 3 can be set according to the actual working condition, and can be a H-shaped, T-shaped or π-shaped (the ends are straight and not bent), the two ends in the first direction (for example, the horizontal part of the above-mentioned shape) are connected with the side edges of the limiting vertical plates 2 to realize stable and suspended arrangement, and the second direction (for example, the vertical part of the above-mentioned shape) is located between the two groups of positionally opposite limiting vertical plates 2, and the top surface is used to support the horizontal end of the lattice column component, and the vertical end of the lattice column component is freely arranged between the limiting vertical plates 2 and the horizontal supporting plate 3.

[0036] As to the connecting mode of the horizontal supporting plate 3 and the limiting vertical plate 2, the actual working condition can be considered, for example, the straight slot two 9 can be arranged on the horizontal supporting plate 3, the straight slot two 9 extends along the connecting direction of the two groups of positionally opposite limiting vertical plates 2, the locking member two 11 is a high-strength bolt penetrating through the straight slot two 9, and the limiting vertical plate 2 is provided with the screw hole two 10 matched with the locking member two 11. When the spacing of the two groups of positionally opposite limiting vertical plates 2 needs to be changed, the locking member one 8 and the locking member two 11 are loosened, the cap end of the locking member one 8 is separated from the outer wall of the straight slot one 6, the cap end of the locking member two 11 is separated from the outer wall of the straight slot two 9, the triangular supporting frame 5 and the limiting vertical plate 2 can be slid along the extension direction of the straight slot one 6 (in the same direction as the straight slot two 9). When the spacing is adjusted to be appropriate, the locking member one 8 and the locking member two 11 are tightened (there is no sequence), the cap end of the locking member one 8 is tightly abutted against the outer wall of the straight slot one 6, so that the triangular supporting frame 5 cannot be freely slid, and the cap end of the locking member two 11 is tightly abutted against the outer wall of the straight slot two 9, so that the horizontal supporting plate 3 cannot be slid relative to the limiting vertical plate 2.

[0037] The horizontal supporting plate 3 can be slidably connected with only one side of the limiting vertical plate 2, and fixed with the limiting vertical plate 2 on the other side by using common screw holes and bolts in one-to-one correspondence; or the horizontal supporting plate 3 can be slidably connected with both sides of the limiting vertical plate 2, which is not limited here.

[0038] In addition, the embodiment also provides a scheme 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 for connecting the semi-finished products, the two semi-finished products are arranged opposite to each other in up and down directions, the openings of the two semi-finished products are opposite to each other, the lower semi-finished product is placed on the base 1, and the upper semi-finished product is placed on the horizontal supporting plate 3; the triangular supporting frame is pushed to make the limiting vertical plates 2 on the two sides of the semi-finished products close to each other to a spacing equal to the side length of the single lattice column; the length of the telescopic rod 4 is adjusted to make the telescopic rod 4 abut against the close faces of the two vertical ends of the semi-finished product, and the far faces of the two vertical ends of the semi-finished product are respectively abutted against the limiting vertical plates 2 on the two sides, wherein the number of the telescopic rods 4 is increased or decreased according to the requirement, and the telescopic rods 4 for supporting should be arranged on the two semi-finished products respectively; finally, the steel plate is welded on the two semi-finished products at the gap between the limiting vertical plates 2 on the same side of the single lattice column.

[0039] However, when this efficient assembly scheme is used, it should be noted that a plurality of screw holes two 10 with different heights need to be arranged on the limiting vertical plate 2 according to the side length of the lattice column, for adjusting the installation height of the horizontal supporting plate 3, so that the spacing between the two semi-finished products meets the requirement.

[0040] The telescopic rod 4 can be arranged to include a middle rod 4-1 and end rods 4-2 located at both ends of the middle rod 4-1, and the end rods 4-2 extend in the same direction as the middle rod 4-1 and are connected in a sliding manner (which can be a sliding sleeve, that is, one of the middle rod 4-1 and the end rod 4-2 is hollow to accommodate the other). The fixed locking mode can be that a plurality of screw holes three 12 are arranged on the middle rod 4-1 and the end rod 4-2 along the axial direction, respectively, and the corresponding screw holes three 12 on the middle rod 4-1 and the end rod 4-2 are provided with locking pieces three 13, which can be high-strength bolts. By changing the position of the locking piece three 13, the length of the telescopic rod 4 can be changed. The fixed locking mode can also be that one of the middle rod 4-1 and the end rod 4-2 is provided with external threads, and the other is provided with threads. The threads are fastened, and the length of the telescopic rod 4 can be changed by rotating.

[0041] In addition, a pressing plate 4-3 can also be arranged at the apart end of the two groups of end rods 4-2, and the size of the pressing plate 4-3 is greater than the cross-sectional size of the end rod 4-2. The contact area with the lattice column component 15 is increased, and the support stability is improved.

[0042] When assembling the composite lattice column, the horizontal support plate 3 can be arranged in the shape of π, and the two parallel ends thereof are respectively arranged on different single lattice columns, and the same mode as above is adopted to weld the steel plate or other steel members serving as connecting members between the adjacent single lattice columns.

[0043] Compared with the prior art, the utility model has the beneficial effects that: the lattice column component 15 is hung by the horizontal support plate 3, the distance between the two groups of opposite lattice column components 15 which have not been welded is limited by the spacing adjustable limiting vertical plate 2, the lattice column component 15 is abutted by the telescopic rod 4, the distance between the two groups of opposite lattice column components 15 which have not been welded is adjusted at one time by the limiting vertical plate 2, and then the connecting steel plate is welded, so that the influence of the precision and efficiency caused by the repeated adjustment of the distance between the two groups of opposite lattice column components 15 which have not been welded in the construction can be avoided. Meanwhile, the jig frame is a shaped member, and the pass type and direction thereof are pre-set, for example, the direction and precision of the straight slot one 6 and the straight slot two 9, and when the adjustment is made, the locking piece one 8 and the locking piece two 11 are loosened or tightened, and the related components are pushed along the above-mentioned slots, so that the adjustment precision is not affected by the experience and skills of the construction personnel. The jig frame can be used not only for assembling the single lattice column, but also for assembling the composite lattice column by assembling a plurality of single lattice columns, and the practicality is high.

[0044] The above is the preferred embodiment of the utility model, and it should be pointed out that for ordinary technical personnel in the technical field, a number of improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model.
