Description
Technical Field
The utility model belongs to the technical field of building construction, and particularly relates to an adjustable post-cast strip supporting column.
Background
The post-cast strip is a concrete strip which is reserved in structures such as beams, plates (including foundation slabs) and walls and has a certain width and is poured after a certain time in order to adapt to the influences of factors such as environmental temperature change, concrete shrinkage and uneven structure settlement. Most structural design is simply supported beam slab in modern building, because keeping somewhere of post-cast strip, the cantilever beam slab is changed into to the structure atress, consequently need add in post-cast strip department and establish the support, avoids causing beam slab cantilever root fracture because of the structural deformation that factors such as concrete dead weight produced, reduces the seepage risk in structure face later stage.
In a construction site, the post-cast strip is traditionally supported independently by support frames, and after concrete pouring is completed and strength is achieved, the support frames are kept not to be detached, so that cracks are prevented from appearing at the post-cast strip. The existing support frame occupies a large space, and the passing space of the basement can be influenced. In part of construction sites, plain concrete columns are used as beam lower supports at post-cast strips, and concrete column molds need to be arranged below beams and need to be poured into the concrete to finally form support columns. Although the bearing capacity of the plain concrete support column meets the requirement, the consumed working time is long, the used materials are more, the plain concrete support column cannot be reused, and the resources are wasted.
Disclosure of Invention
In order to solve the problems, the utility model provides an adjustable post-cast strip supporting column which can solve the supporting problem of a beam at a post-cast strip, avoid cracks and can be used repeatedly.
Therefore, the technical scheme of the utility model is as follows: an adjustable post-cast strip supporting column comprises a first support and a second support, wherein the first support and the second support are both of square tube structures, a lifting hook is arranged on the side surface of the first support, a cover plate is arranged above the first support, an anchoring lug is arranged in the middle of the cover plate, and a plurality of first positioning holes which are uniformly distributed are arranged on four surfaces of the first support; a plurality of second positioning holes which are uniformly distributed are formed in four surfaces of the second support, the lower part of the first support is inserted into the second support, and a bolt penetrates through the first positioning holes and the second positioning holes to fix the first support on the second support; a blocking strip is arranged inside the second support, and a base is arranged below the second support.
Preferably, the radial cross sections of the first stent and the second stent are both square, and the length of the side of the first stent is smaller than that of the side of the second stent.
Preferably, the positions of the first positioning holes on two opposite surfaces of the four surfaces of the first support correspond to one another one by one, and the positions of the first positioning holes on two adjacent surfaces are staggered with one another; in the four surfaces of the second support, the positions of the second positioning holes on two opposite surfaces are in one-to-one correspondence, and the positions of the second positioning holes on two adjacent surfaces are staggered.
The first support and the second support are fixedly connected through bolts, and a first positioning hole and a second positioning hole in proper positions can be selected as required, so that the overall height of the support column is adjusted, and a plurality of bolts can be installed for strengthening stability; the lifting hooks on the two sides of the first support can be used for completing the lifting, shifting and other works of the support column; the second support is internally provided with a stop bar which can prevent the first support from falling to the bottom of the second support.
When the post-cast strip beam is used, the supporting columns are adjusted to be at proper heights and then are hoisted to the cantilever ends of the beam at the post-cast strip, and gaps between the supporting columns and the beam bottom are closed by adopting wood moulds and are fastened and reinforced step by step; concrete is poured on the floor, and the post-cast strip beam and the support column are connected into a whole through a small section of concrete and provide supporting force. After construction, the supporting columns can be detached.
The utility model has simple structure and convenient installation, can be used repeatedly, reduces the construction cost and improves the construction efficiency; the whole length of support column is adjustable, can provide the holding power to the post-cast strip of co-altitude not, avoids the emergence of crack.
