Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, the utility model discloses a concrete pillar steel reinforcement cage fixed knot constructs, establish pillar template 2 on steel reinforcement cage 1 including the cover, pillar template 2's lower extreme is fixed in on basis 3, be equipped with between steel reinforcement cage 1 and the pillar template 2 and be used for adjusting adjustment mechanism 4 of distance between steel reinforcement cage 1 and the pillar template 2, adjustment mechanism 4 includes screw rod 41 and nut 42, the one end of screw rod 41 and pillar template 2's inner wall butt, the other end and nut 42 screw-thread fit, nut 42 is fixed on steel reinforcement cage 1's the main muscle 11.
The nut 42 may be fixed to the main bar 11 by welding or by clamping with a clamping mechanism. The embodiment of the utility model provides an in, nut 42 passes through curved overlap joint muscle 43 welding on adjacent main muscle 11 to reduce the atress of single main muscle, prevent single main muscle atress deformation.
Specifically, the lower end of the pillar formwork 2 may be fixed to the foundation by bolts.
The number of the adjusting mechanisms 4 is usually multiple, and the specific positions can be preset or set on site according to needs. But the site setting is inconvenient, and the construction efficiency can be influenced.
This steel reinforcement cage fixed knot constructs sets up adjustment mechanism 4 between adjustment steel reinforcement cage 1 and pillar template 2, after pillar template 2 is fixed, can be through the change screw rod 41 of the adjustment mechanism 4 of the less department of rotatory pillar template 2 and 1 interval of steel reinforcement cage, make its 41 stretch out to can make steel reinforcement cage 1 remove or warp to opposite direction, and then reach fixed steel reinforcement cage 1, adjust the distance between steel reinforcement cage 1 and the pillar template 2, the purpose of control steel reinforcement cage protective layer thickness. This steel reinforcement cage fixed knot constructs only needs can reach the purpose of control steel reinforcement cage protective layer thickness through rotatory corresponding screw rod 41, not only can improve the quality of construction, and the adjustment is convenient, and is with low costs.
Along steel reinforcement cage 1's direction of height, because the bending deformation degree of each part of steel reinforcement cage 1 is inconsistent, for the distance between more convenient control steel reinforcement cage 1 and the pillar template 2, in the embodiment of the utility model, be equipped with the multiunit adjustment mechanism group along steel reinforcement cage 1's direction of height interval arrangement between steel reinforcement cage 1 and the pillar template 2, every adjustment mechanism group of group includes four adjustment mechanism 4, and the adjustment mechanism 4 of every adjustment mechanism group is annular equipartition on steel reinforcement cage 1. Therefore, the distance between the corresponding position of the reinforcement cage 1 and the pillar formwork 2 can be adjusted through each adjusting mechanism group. Each adjusting mechanism group comprises four adjusting mechanisms 4, the adjusting mechanisms 4 of each adjusting mechanism group are annularly and uniformly distributed on the steel reinforcement cage 1, and therefore, the screw rods 41 of the four adjusting mechanisms 4 in each adjusting mechanism group are adjusted, the extending length of each screw rod 41 is enabled to be suitable, the steel reinforcement cage can be fixed from four directions, and the relative position relation between the steel reinforcement cage and the pillar formwork 2 can be better guaranteed. After adopting above-mentioned structure, can be when the steel reinforcement cage production with every adjustment mechanism group establish on the steel reinforcement cage in advance.
The height of the concrete column is generally high and its column formwork 2 is generally constructed from a plurality of sections of formwork units 21 joined end to end in sequence. When the pillar form 2 is formed by connecting the multiple sections of form units 21 end to end in sequence, a certain coaxial error also exists between the multiple sections of form units 21, and therefore, a group of adjusting mechanisms is correspondingly arranged in each section of form unit 21. The structure can better ensure the space between the reinforcement cage 1 and each section of template unit 21 and can better control the thickness of the protection layer of the reinforcement cage.
In order to better control the shape of the reinforcement cage, an annular framework rib 12 for shaping the reinforcement cage 1 is arranged between two adjacent groups of adjusting mechanisms, the annular framework rib 12 is arranged on the inner side of the reinforcement cage 1, and a support frame 13 is arranged in the annular framework rib 12. The supporting frame 13 is used for improving the rigidity of the rib 12, and the supporting frame 13 can be in a cross-shaped or triangular structure. After being equipped with annular skeleton muscle 12 that is used for setting steel reinforcement cage 1 between adjacent two sets of adjustment mechanism groups, the steel reinforcement cage is in the region of transport, the main deformation of hoist and mount in-process takes place in annular skeleton muscle 12 both sides, and this region just in time corresponds with every group adjustment mechanism group, promptly: the deformation area can be controlled in the area where the adjusting mechanism group is arranged, so that the thickness of the protective layer of the reinforcement cage can be controlled more conveniently through the adjusting mechanism 4.
In the circumferential direction of the reinforcement cage, the setting of the adjusting mechanisms 4 of each adjusting mechanism group can be the same (see fig. 1), and also can be arranged in a staggered manner, so that the two adjacent upper and lower adjusting mechanisms 4 are not on the same vertical line. In order to be able to limit the position of the reinforcement cage from more directions and thus to better control the thickness of the protective layer of the reinforcement cage, the adjusting mechanisms 4 of two adjacent adjusting mechanism groups are optimally arranged in a staggered manner.
