Description
Technical Field
The utility model relates to an assembly technical field who divides the die sinking especially relates to a precast beam column mould end board of easy installation dismantlement.
Background
The assembly type building is a new building construction mode, and is not like a traditional building, bricks are built one by one or poured one by one, but like building blocks, all prefabricated parts are assembled one by one to form the building. Most of the work during construction is performed in a prefabrication yard, not on a construction site, where only simple assembly work is performed, so that the construction period is extremely short and the noise and dust pollution are extremely small. Since 2015, China began to vigorously popularize assembly type buildings, and a series of policies were developed to encourage the development of assembly type buildings.
The kinds of prefabricated members used in fabricated buildings vary greatly according to construction conditions, but prefabricated beams and prefabricated columns are inevitably used as load-bearing members. When the precast beam and the precast column are connected with other parts, in order to ensure the connection stability, the main bars of the reinforcement cages of the precast beam and the precast column need to be crossed, and sometimes, the reinforcing bars need to be connected by using members such as grouting sleeves. This also requires that the precast beams and the precast columns have the reserved steel bars left at the ends thereof to extend out of the concrete.
When the precast beam and the precast column are poured, the operation of extending the main reinforcement to the outside of the mold to form the reserved reinforcement is called as the rib throwing, the rib throwing also means that the reserved reinforcement passes through the end plate of the mold, and the end plate is provided with a main reinforcement hole. In order to ensure the smooth assembling process, the reserved steel bars are bent according to the use scene so as to be assembled with parts with angles such as a sloping roof and the like. Because the reserved steel bars are thick, workers in a pouring site cannot bend the reserved steel bars, the reserved steel bars are bent well when the reinforcement cages are bound, and then the reserved steel bars are placed into a die (in the shape of a long groove) for pouring. This, however, presents great difficulties in the installation of the end plates of the mould.
Because the processing of the end plate and the bending of the reserved steel bar are separately carried out, the tolerance is easy to accumulate; and when the end plate is installed, the end plate needs to move along the bent reserved steel bars under the condition that a plurality of reserved steel bars are sleeved at the same time, which can be almost not completed, almost all the end plates can be clamped on a half way in actual construction, and the disassembly is carried out on the premise that the reserved steel bars and main reinforcement holes are stained with a large amount of solidified mortar, so that the difficulty is higher. In actual construction, in order to enable the end plate to be installed reluctantly, the main rib holes are generally required to be reamed to a degree much larger than the main ribs, and part of the main rib holes are required to be changed into waist holes. This leads to supporting sealing member to block up the main muscle hole very difficultly, and the end board is sealed totally very difficultly, leaks to starch seriously, and the concrete spare tip of pouring is irregular, and even so, the installation of end board is dismantled still comparatively difficultly, needs to dismantle with the mode violence installation of hammering, leads to the end board to damage very fast.
The applicant finds that complete main rib holes on the end plate are easy to be clamped when more than one row of the complete main rib holes are formed in the end plate, but the complete main rib holes are not easy to be clamped even if the number of the complete main rib holes is large.

as shown in fig. 4, step one: installing and fixing a bottom plate 1 on a template 5 at the bottom of the precast beam column mould, and screwing bolts into bolt holes 73 on folded edges 71 of the bottom plate 1 to fix the bottom plate 1 on the template 5 of the bottom plate 1 during installation; then, the reinforcement cage 6 is erected on the bottom plate 1, so that the main reinforcement at the bottom of the reinforcement cage 6 falls into the corresponding main reinforcement hole 72 on the bottom plate 1.
As shown in fig. 5, step two: and (3) installing the templates 5 at two sides of the precast beam column mold, then installing and fixing the side plates 2 on the templates 5 at two sides respectively, enabling the main reinforcements at two sides of the reinforcement cage 6 to enter corresponding main reinforcement holes 72 on the side plates 2, and screwing bolts into bolt holes 73 on folded edges 71 of the side plates 2 during installation to fix the side plates 2 on the templates 5 at the side parts. Of course, the sequence of the installation of the formworks 5 on both sides and the installation of the side plates 2 can be reversed, that is, the side plates 2 are firstly slid to the installation position along the main ribs, and then the formworks 5 are installed and the formworks 5 and the side plates 2 are connected.
As shown in fig. 6, step three: the center plate 3 is installed so that the main reinforcement in the middle of the reinforcement cage 6 enters the corresponding main reinforcement hole 72 of the center plate 3.
As shown in fig. 7, step four: the unit plates are connected together by connecting plates 4, here again by bolts passing through the connecting plates 4 and through bolt holes 73 in the unit plates.
In addition, be the hollow square matrix of individual layer to this kind of main muscle and arrange, and the steel reinforcement cage 6 of aligning about the main muscle one-to-one of 6 tops of steel reinforcement cage and bottom, can also arrange the cell board like this:
except the bottom plate 1, the unit plate further comprises two side plates 2 anchored on the inner sides of the formworks 5 on the two sides of the precast beam column die respectively and a central plate 3 arranged between the two side plates 2, the side plates 2 are rectangular plates vertically arranged in the length direction, the lower edges of the side plates are attached to the upper edge of the bottom plate 1, the central plate 3 is divided into two vertically symmetrical plates, and the lower edges of the central plate 3 located below are attached to the upper edge of the bottom plate 1.
