Description

Post-pouring strip side support template

Technical Field

The utility model belongs to the technical field of post-cast strips, and particularly relates to a post-cast strip side support template.

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 in order to prevent harmful cracks possibly generated by uneven self shrinkage or uneven settlement of a reinforced concrete structure in building construction.

There are upper layer steel bar 102 and lower layer steel bar 103 on the post-cast strip, and upper layer steel bar 102 and lower layer steel bar 103 stretch into the post-cast strip, guarantee intensity. Prior to casting, battens 101 are secured to the mesh reinforcement on both sides of the post-cast strip. As shown in fig. 1, the formwork formed by the battens 101 divides the casting space into 3 spaces, two casting areas 104 and 105 are positioned at two sides, a post-casting belt 106 is positioned between the two casting areas, and when the casting machine works, the casting process needs to be strictly controlled, so that concrete is prevented from entering the post-casting belt when the casting areas are cast.

The template comprises battens 101, gaps are reserved between adjacent battens 101, upper layer steel bars 102 and lower layer steel bars 103 penetrate through the gaps between the battens 101, and through the arranged battens 101, concrete is prevented from entering the post-cast strip, and the construction quality of the post-cast strip is guaranteed.

However, this structure has the disadvantage that: due to the arrangement of the upper layer of steel bars 102 and the lower layer of steel bars 103, the battens 101 are required to be placed block by block, so that the upper layer of steel bars 102 and the lower layer of steel bars 103 are spaced apart, the width of each batten 101 is 150 mm-200 mm, and a large amount of labor and time can be consumed during placement. In addition, reserving the clearance that can let upper reinforcing bar 102 and lower reinforcing bar 103 pass through between the square, there is concrete to leak in this clearance easily, in order to solve this problem, often to the condition of filling plastic cloth in the clearance in prior art, later stage pouring still needs the clearance, has increased the clearance degree of difficulty.

To solve this problem, in the prior art, a comb-shaped mold plate is provided, as shown in fig. 2, and the comb-shaped mold plate includes two mold plates, a gap is reserved between the two mold plates, the gap is used as a post-cast strip 106, and the space is equally divided into three areas by the two mold plates, two pre-cast areas 104.105 located at two sides and the post-cast strip 106 located in the middle.

The template structure is: the tooth grooves 108 which can allow the upper layer steel bars 102 and the lower layer steel bars 103 to pass through are reserved on the templates 107, and the influence of the templates on the upper layer steel bars 102 and the lower layer steel bars 103 is avoided through reserving the tooth grooves 108. In practice, the template 107 may be fixed to the preset wire mesh 109.

The structure can avoid concrete from entering the post-pouring belt 106, and meanwhile, the construction efficiency is improved.

The structure has the following defects: because the upper layer steel bar 102 and the lower layer steel bar 103 extend into the post-pouring belt, no gap exists between the upper layer steel bar 102 and the lower layer steel bar 103 and the post-pouring belt, the comb-tooth type template 107 can not be placed again after the upper layer steel bar 102 and the lower layer steel bar 103 are placed. Therefore, the order of placement of the templates and the reinforcing bars needs to be adjusted: during construction, the reinforcement mesh 109 needs to be fixed with the mesh paved in advance; subsequently, two comb-tooth templates 107 are fixed to the reinforcing mesh 109; and then, the upper layer steel bars 102 and the lower layer steel bars 103 pass through tooth grooves 108 on the comb-shaped templates 107 one by one, and finally, concrete pouring is carried out.

The placement mode greatly reduces the probability of concrete leakage into the post-pouring belt 106, ensures the construction quality of the post-pouring belt, but the problem of low construction efficiency still exists because the steel bars pass through one by one after being placed by the comb teeth, and meanwhile, the steel bars collide with the comb teeth type template 107 in the process of placing the steel bars, so that the template 107 shifts, and the construction efficiency is further influenced.

Detailed Description

In embodiment 1, as shown in fig. 3 to 9, the post-cast strip side support template comprises two side molds, and a gap is reserved between the two side molds, wherein the gap is the reserved post-cast strip. When the method is implemented, two sides of the two side dies are poured firstly, and then the space between the two side dies is poured.

The two side dies comprise die frames 1, the die frames 1 comprise two opposite supporting frames 7, the supporting frames 7 are vertically arranged, the cross section of each supporting frame 7 is U-shaped, and U-shaped openings of the two supporting frames 7 are oppositely arranged; a connecting steel plate 8 is welded between the two opposite supporting frames 7, so that the stability of the supporting frames 7 is ensured.

An upper die 4 and a lower die 6 positioned below the upper die 4 are arranged between the two supporting frames 7; in the implementation, the upper die 4 and the lower die 6 are clamped in the supporting frame 7.

An upper reinforcement groove 10 with an upward opening is arranged on the upper die 4, and a lower reinforcement groove 9 with a downward opening is arranged on the lower die 6. The upper steel bar groove 10 and the lower steel bar groove 9 which are arranged correspond to the existing upper layer steel bar 2 and lower layer steel bar 3, so that the side die does not affect the upper layer steel bar 2 and the lower layer steel bar 3, and the pouring requirement is guaranteed.

The closing of the casting space is achieved by placing the upper die 4 and the lower die 6 into the support frame 7.

In order to adapt to different pouring thicknesses, at least 1 middle die 5 is further arranged between the upper die 4 and the lower die 6, in this embodiment, the number of the middle dies 5 is 1, and of course, the height of 1 middle die 5 is insufficient, and two middle dies 5 or even more middle dies 5 can be arranged. In the implementation, the upper die 4, the lower die 6 and the middle die 5 are not fixedly connected, only are attached, and in order to ensure the attaching firmness of the upper die 4, the lower die 6 and the middle die 5, the upper die 4 and the supporting frame 7 are connected through bolts.
