Description
Technical Field
The utility model belongs to the technical field of post-cast strip formwork, concretely relates to post-cast strip independent support combined frame.
Background
The post-cast strip is a concrete strip reserved at corresponding positions of a foundation slab, a wall and a beam according to design or construction specification requirements for preventing harmful cracks possibly generated by uneven self shrinkage or uneven settlement of a cast-in-place reinforced concrete structure in building construction, temporarily divides the structure into a plurality of parts, pours and smashes construction joint concrete after a plurality of times after the internal shrinkage of a member, and connects the structure into an integral zone.
The post-cast strip is a concrete rigid joint and is suitable for structures which are not suitable for setting flexible deformation joints and tend to be stable in later deformation. At present, post-cast strips are widely used as technical measures for preventing temperature expansion joints of super-long buildings and settlement joints between high-rise parts of high-rise buildings and skirt houses.
In the prior construction, a support system of the overlong top plate is erected into an integral structure, a support is firstly erected at the position of a post-cast strip before the support system is detached, when the support system of the integral structure is detached, the first support system at the position of the post-cast strip is also detached, and at the moment, the support system needs to be erected for the second time at the position of the post-cast strip to support the post-cast strip template. When the post-cast strip is improperly managed on site, the post-cast strip is not jacked in advance or in time, or part of supports of the post-cast strip are removed due to cleaning of the post-cast strip, and the like, the top plate post-cast strip is separated due to the factors such as the self weight of the structure, the construction load and the like, so that the top plate is artificially cantilevered, and the top plate is cracked.
The following phenomena and problems easily occur in the twice formwork erecting of the post-cast strip: 1. dismantling the post-cast strip support of the beam plate to change the beam plate into a cantilever member, and changing the stress mode of the beam plate so as to cause the root of the beam plate to have cracks; 2. the post-cast strip support is reinforced again after being detached, and actually, the stress mode of the beam plate is changed at the moment of detaching the post-cast strip support, deformation is generated, and the re-reinforcement only plays a role in not continuously deforming; 3. the supporting points are reserved at the beam bottoms, the beam plates adopt secondary formwork support, and in the condition, because the contact between the formwork and the concrete surface is not tight, when concrete is poured in the post-cast strip, concrete grout is extruded along the gaps, and the new concrete at the joint of the new concrete and the old concrete is easy to protrude outwards and leak grout. Therefore, it is necessary to design a post-cast strip support frame to support the post-cast strip template and form an independent template supporting system.
In the prior art, a beam plate post-cast strip template support frame (application number: 201310606119.9) consists of a section steel support frame and peripheral steel pipe scaffolds, wherein the section steel support frame is arranged at the beam bottoms at two sides of a post-cast strip and is close to the post-cast strip, the peripheral steel pipe scaffolds are positioned at the plate bottoms at two sides of the post-cast strip and around the section steel support frame, and the section steel support frame is enclosed and connected with the section steel support frame into a whole; the peripheral steel pipe scaffold comprises post-cast strip plate bottoms and vertical rods at beam bottoms. Although the problem of disassembling from the full scaffold is solved, the problem of inflexible dismantling still exists.
SUMMERY OF THE UTILITY MODEL
It is an object of the present invention to solve at least the above problems and to provide at least the advantages which will be described later.

Compared with the prior art, the utility model has the advantages that:
1. the formwork is laid separately, the frame body is erected independently, the roof formwork and the support frame body outside the range of the post-cast strip are not limited by connection with the post-cast strip when the roof formwork and the support frame body are dismantled, and the formwork and the support frame body form a completely independently arranged frame body support. The purpose of quick disassembly is achieved, the lease cost of a large amount of turnover materials is saved, and the turnover utilization rate of the materials of the template and the square timber is improved.
2. Compare with traditional post-cast strip formwork support body, traditional support body is whole to be supported, wholly sets up, if want to demolish support template and support body outside the post-cast strip scope during demolish then need demolish the support frame in post-cast strip. This scheme can not receive the influence of post-cast strip support system when post-cast strip both sides template is demolishd through post-cast strip support frame and inner tower separation, satisfies the post-cast strip scope and supports the requirement of can not demolishing. And the construction mode of illegal support replacement during the previous removal of the post-cast strip template is avoided. The construction cost of secondary topping is reduced.
3. In the construction process, workers can support and adjust the height and the support frame without erecting a frame body to a top jackscrew.
4. The size of the supporting range is adjusted by using the adjustable telescopic rod, and the size is not limited by the fixed modulus of the traditional horizontal connecting rod.
