Description

Assembled lattice column reinforcing apparatus

Technical Field

The utility model belongs to the lattice column reinforcement technology, and particularly relates to a basic lattice steel column assembly type reinforcement device of a tower crane, which can be repeatedly used, save raw materials and reduce labor intensity and technical requirements of site constructors.

Background

A tower crane (tower crane for short) is an essential mechanical device for building construction. For stable operation of the tower crane, under the foundation of the tower crane, lattice type steel columns (lattice columns for short) are used for supporting the foundation of the tower crane and the load of the whole tower crane so as to ensure the stability of the whole tower crane.

The design and construction of the tower crane foundation are the preceding steps before entering the tower crane. With the development of society, urban buildings have increasingly demanded underground space, the original basement of one floor cannot meet the demand, and the basement of a common building generally needs more than 2 floors. According to the construction procedure of excavating and supporting the foundation pit and then installing the tower crane, the tower crane which is close to the center of the foundation pit faces the difficult problem that the tower crane cannot be installed. The lattice column type tower crane bearing platform can well solve the contradiction, and the installation of the tower crane is completed before the deep foundation pit is excavated and supported, so that the tower crane is also beneficial to being put into use in advance. The lattice column type tower machine bearing platform consists of a reinforced concrete bearing platform and 4 lattice columns. Each lattice column is formed by splicing four angle steel and batten plates, reinforced concrete bearing platforms are arranged at the tops of the 4 lattice columns within a certain range, the bottoms of each lattice column are connected with one bored concrete pile, and the lattice columns are inserted into the bored cast-in-situ pile.

With deep excavation of the foundation from the ground, the length of the exposed surface of the lattice column gradually increases, particularly, the length of the lattice column reaches about 20m in a plurality of commercial center basement rooms, the tower crane is turned on or braked to generate extremely large turning torque on a foundation bearing platform in a working state, and the torsion resistance requirement cannot be met by supporting the lattice column under the bearing platform by 4 independent lattice columns, so that 4 lattice columns are required to be interconnected and reinforced by using a transverse strut and a diagonal strut to obtain the integral strength in order to prevent the lattice column from being integrally unstable under the action of the turning torque of the tower crane. The existing reinforcement measure is that in the process of excavation, when the transverse support node elevation position is excavated, transverse support and diagonal support manufacturing of the support section are immediately carried out, the transverse support and the diagonal support generally adopt angle steel which is the same as the composition of the lattice columns, and the lattice columns are reinforced by cross welding between the lattice columns through the transverse support and the diagonal support.

The aforementioned manner of reinforcing the lattice columns by cross-welding between the lattice columns by means of the cross braces and the diagonal braces has the following drawbacks:

1. because the welding condition of the construction site is poor, the welding operation space is narrow, and the construction is difficult;

2. the requirements on welding on site are high, the reinforcement surfaces of the lattice columns are often not on the same straight line (the parallelism of the vertical surfaces of the four lattice columns is difficult to control when the vertical surfaces of the four lattice columns are inserted into pile holes), and triangular steel plates are arranged between angle steel and the lattice columns for reinforcement, so that the reliability of welding joints is difficult to ensure;

3. after the lattice column is excavated, the stability of the foundation of the tower crane is reduced, so that the tower crane needs to stop working when not reinforced, and the continuous operation is usually required for 3-5 days when the site welding is adopted for one-time reinforcement, and the shutdown will generate higher time cost. Even some construction sites use tower cranes as usual before the reinforcement is completed in order to rob the construction period, and great potential safety hazards exist.

Therefore, research on a tower crane foundation lattice column reinforcing device is very necessary to realize quick, effective, safe and reliable reinforcement.

Hoop 100 includes two identical hoop bodies 101 surrounding lattice columns and connected as a hoop. As shown in fig. 3-4, each hoop body 101 has two right angle sides 105. Therefore, as shown in fig. 1, the included angle 106 of the two hoop bodies 101 is opposite and the corresponding right-angle sides are connected to form the square hoop ring 100. The connection between the right-angle sides 105 is made by abutting the end face 107 of one right-angle side against the side face 108 of the other right-angle side and connecting the two sides by means of a fastening bolt 109. The fastening bolt 109 is provided at the connection portion with a first reinforcing structure 110, and the first reinforcing structure 110 is a block structure welded to the side surface of the right-angle side for increasing the strength of the right-angle side and the length of the thread connected to the fastening bolt 109.

The hoop 100 is provided with a locking structure for locking the hoop to the lattice column. The locking structure is a locking bolt 111 which is connected to the hoop body 101 and extends into the hoop ring to be tightly propped against the lattice column. A second reinforcing structure 112 is arranged on the hoop body 101 at a position where the locking bolt 111 is connected. The second reinforcing structure 112 is like a column and is threaded therein, thereby increasing the strength of the anchor body and the threaded connection length of the locking bolt.

The corner of the hoop 100 is provided with a connecting seat, which as shown in fig. 3-4 comprises a three-hole connecting seat 102 and a single-hole connecting seat 103, the three-hole connecting seat and the Shan Konglian seat on one hoop body are rotationally assembled on the hoop body through the same shaft 113, the three-hole connecting seat is provided with three first pin holes 104, and the single-hole connecting seat is provided with one first pin hole 104. Therefore, the three-hole connecting seat is connected with other connecting seats in the overall peripheral elevation plane system of the lattice column through the three stay bar assemblies 200 for supporting and reinforcing the overall peripheral elevation plane system of the lattice column, and the single-hole connecting seat 103 is connected with an oblique connecting seat in the internal three-dimensional space of the lattice column through one stay bar assembly for supporting and reinforcing the oblique three-dimensional space of the overall internal of the lattice column.

The stay bar assembly 200 comprises two sections of connecting rods 201 connected along the length direction and a screw rod 202 positioned between the two sections of connecting rods, threads at two ends of the screw rod 202 are opposite in rotation direction, two ends of the screw rod are respectively connected with one end of one section of connecting rod through threads, and connecting lugs 203 are arranged at the other ends of the two sections of connecting rods, so that two ends of the stay bar assembly are provided with one connecting lug. The connecting lug 203 is provided with a second pin hole 204, and the screw 202 is provided with a screwing structure 205. The connecting rod 201 forming the stay bar assembly comprises at least two steel pipes 206 extending in the same direction and uniformly distributed circumferentially, one end of each steel pipe 206 is welded with a nut 207 for connecting with a screw, and the other end of each steel pipe 206 is welded with a connecting lug 203.

The pin 300 is used for being inserted into the first pin hole 104 and the second pin hole 204 to connect the connecting lug at one end of the stay bar assembly to the connecting seat of one hoop.

In the above-described assembled lattice column reinforcement device, when reinforcing the lattice columns, two hoop bodies 101 are connected around one lattice column with fastening bolts 109 in a connection relationship as shown in fig. 1 at the elevation position of the cross brace joint of each lattice column, and locking bolts 111 are pressed against the lattice columns to fasten the hoop to the lattice columns. Accordingly, the strut assembly 200 is connected between the three-hole connecting seats 102 corresponding to the positions on each hoop, namely, the connecting lug 203 at one end of the strut assembly is connected to the connecting seat of one hoop by inserting the pin 300 into the first pin hole 104 and the second pin hole 204, and then the screw 202 is rotated by the screwing structure 205 to tighten the strut assembly 200, so that the assembly and installation can be completed, and the strut assembly 200 plays a role in strengthening as a welded cross brace and diagonal brace for supporting and strengthening the whole peripheral elevation plane system of the lattice column. This case of support reinforcement is shown in fig. 2 and 7. Furthermore, as shown in fig. 5-7, the 4 lattice column reinforcing surfaces are not on the same straight line, however, with the foregoing fabricated lattice column reinforcing apparatus, this disadvantage can be overcome because the three-hole connection base can be pivoted.

As shown in fig. 3-4, when the corner of one hoop body 101 is assembled with the three-hole connecting seat 102 and the single-hole connecting seat 103 through one shaft 113, besides supporting and reinforcing the whole periphery elevation plane system of the lattice column through the three-hole connecting seat, the brace rod assembly 200 can be connected between the single-hole connecting seats 103 to support and reinforce the whole internal three-dimensional space of the lattice column in an inclined manner, wherein the inclined direction can be between the opposite angles in the same horizontal support node elevation plane or between the opposite angles in different horizontal support node elevation positions, and the brace rod assembly 200 marked in fig. 8 is the condition of supporting and reinforcing the inclined diagonal angle.

According to the assembled lattice column reinforcing device, for lattice columns with inconsistent sizes, the clamping can be adjusted through the locking bolts so as to fix the hoop on the lattice column. If the types of the lattice columns are different, the specification and the size are large, the matching with the lattice columns can be realized only by changing the length of the right-angle side of the anchor ear body, and the matching can be used for configuring the anchor ear ring and the stay bar components with different specifications for the lattice columns with different specifications.

According to the assembled lattice column reinforcing device, the three-hole connecting seat and the single-hole connecting seat can respectively and freely rotate in a certain range on the same shaft, so that the self-adaptive lattice column shape and position can possibly generate a larger error installation working condition. The three-hole connecting seat and the three stay bar components form the support reinforcement of the overall peripheral elevation plane system of the lattice column, and the single-hole connecting seat and the single stay bar components are connected to form the oblique reinforcement of the three-dimensional space inside the lattice column.

According to the assembled lattice column reinforcing device, the single-hole connecting seat is positioned in the middle of the three-hole connecting seat, and the single-hole connecting seat and the three-hole connecting seat can rotate independently and do not interfere with each other, so that the problem of contradiction between node arrangement collected by a plurality of stay bar assemblies at the same reinforcing point is effectively solved.

Above assembled lattice column reinforcing apparatus adopts two segmentation structures, and realizes the adjustment of length and pretightning force through the screw rod, compares with traditional on-the-spot welding formula reinforcement, has improved the effect of reinforcement effectively. The cross section size and the number of the used steel pipes depend on the cross section area of the lattice column, and the requirements of the related technical standards on 'the cross section area of the diagonal brace is preferably larger than the cross section area of the lattice column by increasing or decreasing the number of the steel pipes and changing the size of the configured steel pipes'. Furthermore, the arrangement of the steel pipes can be changed to obtain a satisfactory moment of inertia of the cross section of the rod, so that the aims of meeting the strength of the rod, saving materials and reducing the weight of the rod can be achieved.

The assembled lattice column reinforcing device is standardized by adopting an assembled structure, so that the number of the reinforced roads is not limited for a specific lattice column, and the higher the height of the lattice column is, the more the number of the reinforced roads is, so that the actual reinforcing effect is easy to achieve.

According to the assembled lattice column reinforcing device, all parts can be reused; the size of the parts can be well close to the allowable size of the actual reinforcement operation space, the difficulties of material in-out, hoisting and consolidation during reinforcement are reduced, and the time and labor intensity of the reinforcement operation are greatly reduced, so that the method is beneficial to improving economic and social benefits.
