Technical Field
The utility model relates to the technical field of foundation reinforcement of construction hoisting machinery, in particular to a lattice column diagonal bracing reinforcement device for a tower crane foundation.
Background
Along with social development, urban buildings have higher and higher requirements for underground space, and the original basement layer cannot meet the requirements, so that the basement layer of the modern urban building is generally more than 2. Often adopt 4 lattice columns as the support below this kind of building site tower crane foundation cushion cap, it is reinforced with 4 lattice columns to do the bracing along with the excavation needs of basis, and current reinforcement measure adopts L160X 14's angle steel to weld between the lattice column after mainly the on-the-spot measurement size and reinforces.
Because the welding conditions of a construction site are poor, the spaces of a plurality of welding positions are narrow and small, the requirement on welders in high-altitude operation is high, the reinforcing surfaces of the lattice columns are often not on the same straight line, and a triangular steel plate is required to be arranged between the angle steel and the lattice columns for reinforcing, so that the reliability of the welding connection position is often not ensured. In addition, the stability of the foundation of the tower crane is reduced after the lattice column is excavated, the tower crane is not allowed to be used at the moment, continuous operation is usually needed for 3-5 days when one-time reinforcement is carried out, the construction period is easily delayed, a plurality of construction units still use the tower crane before the diagonal bracing is not reinforced, and great potential safety hazards exist. Therefore, it is necessary to reasonably explore the bracing reinforcing device of the lattice column of the tower crane.

Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following examples.
As shown in fig. 1, a portable reinforcement device for a lattice column of a tower crane foundation comprises a clasping clamp a and a support rod B. The number of the holding clamps is at least two, each holding clamp comprises two clamping plates 1 and two swinging plates 2, and the clamping plates are connected through fasteners (such as bolts and nuts). One of the clamping plates is a main clamping plate (shown in figure 7), the other clamping plate is an auxiliary clamping plate (shown in figure 8), and the swinging plates are rotatably positioned at two ends of the main clamping plate. Every splint are the steel sheet that is the right angle and buckles (the appearance with lattice column is fit for), and the both ends of splint still are equipped with pterygoid lamina 1.2, and the system has a plurality of splint holes 1.3 on the pterygoid lamina, and the fastener is installed and is made main splint and vice splint be connected fixedly in the splint hole.
The both ends in the main splint outside system have pivot seat 1.1 respectively (the inboard of main splint is towards the lattice column), be equipped with on the swing board with pivot seat normal running fit's pivot (omit in the picture), still system on the swing board from last three swing plate hole 2.1 that down arrange in proper order, every swing hole is used for installing a vaulting pole, therefore three vaulting poles can be connected simultaneously to every swing board, every is embraced and presss from both sides can press from both sides the simultaneous connection with the other three armful of putting down position on one side, every is embraced and presss from both sides six armful of joinable at most.
The supporting rods are used for connecting the holding clamps in pairs. The stay comprises a connecting rod 3 and two sleeves 4. The connecting rod both ends system has the external screw thread, and the helical direction of two external screw threads is opposite, and the middle part system of connecting rod has regulation hole 3.1, and one of them sleeve is slightly long, and another sleeve is slightly short, and two sleeves are installed respectively at the both ends of connecting rod.
The inner cavity of one end of the sleeve is provided with an internal thread matched with the external thread, the other end of the sleeve is rotatably positioned on the swinging plate (the end of the sleeve is provided with a connecting seat 4.1), and a pin shaft (omitted in the figure) is inserted between the connecting seat and the hole of the swinging plate to be matched with the sleeve to rotate around the pin shaft. The axis of rotation between the sleeve and the swing plate is perpendicular to the axis of rotation between the clamping plate and the swing plate.
Because the lattice column is standard size and middle hole size and position do not change, embrace to press from both sides the direct mount and fix on lattice column 9, the vaulting pole is fixed with embracing on two adjacent lattice columns again to press from both sides the connection for connect as an organic wholely between the lattice column, increased holistic stability, guaranteed the reinforcement effect. Simultaneously, but the adjustable level angle and the every single move angle between vaulting pole and the embrace clamp to the length of vaulting pole also can be adjusted (insert the stock in adjusting the hole and rotate the connecting rod again and finely tune), can satisfy the installation requirement in various places.
