Embodiment 1

[0050] Example 1, see Figure 1 to Figure 3 , a prefabricated anti-cracking door frame riser for the door opening structure of the inner partition wall of the strip, including a prefabricated door frame riser body 100; the upper part of the prefabricated door frame riser body 100 is provided with an L-shaped gap for placing a prefabricated door head plate 110, a first prefabricated grouting groove 120 is provided on the inner surface of the L-shaped gap along the height direction and the horizontal direction, and the first prefabricated grouting groove 120 is provided on the inner surface of the L-shaped gap along the height direction and the horizontal direction, which may be impermeable The structure can also be a through structure. In this embodiment, the through structure is preferred; when assembling the door opening, the grouting channel is synthesized in the first prefabricated grouting groove and the corresponding spliced ​​prefabricated door head plate prefabricated gr...

Embodiment 2

[0057] Example 2, see Figure 8 to Figure 10 , in the above structure, preferably, the upper end surface of the prefabricated door frame vertical plate body 100 is provided with a third prefabricated grouting groove 122, which is convenient for the prefabricated door frame vertical plate body and the top beam or floor slab or splicing above the prefabricated door frame vertical plate body The installation and connection of the inner partition wall slats is explained in this implementation by taking the inner partition wall slats above the prefabricated door frame vertical plate body as an example; the prefabricated door frame vertical plate body and the inner partition wall spliced ​​above the prefabricated door frame vertical plate body A slurry storage channel is formed between the mating surfaces of the slats, and the mortar storage channel is densely filled with mortar. The secondary connector formed after the mortar solidifies also forms an inner bolt, which has strong coh...

Embodiment 3

[0058] Example 3, see Figure 11 to Figure 14 , in order to meet the requirements of some inner partition wall door openings with higher strength requirements; in the above structure, preferably, the prefabricated door frame vertical plate body is pre-embedded with steel bars 111 .

[0059] In order to further improve the connection strength between the present invention and the prefabricated door head panel, a steel bar insertion sleeve 112 is pre-embedded at the L-shaped notch 110 . When the door opening is actually built, the present invention is assembled together with the matching prefabricated door head plate. The prefabricated door head plate has steel bars protruding from the lower end surface and is inserted into the steel bar insertion sleeve of the L-shaped gap to realize connection, or the prefabricated door head plate is also connected. The pre-embedded steel bar inserting sleeve and the pre-embedded steel bar inserting sleeve at the L-shaped gap are connected by ...

Abstract

The invention discloses a prefabricated anti-cracking door frame vertical board for a ribbon board internal parting wall door opening structure. The prefabricated anti-cracking door frame vertical board comprises prefabricated door frame vertical board bodies; L-shaped notches are formed in the upper parts of the prefabricated door frame vertical board bodies, so that the prefabricated door framevertical board bodies are connected with prefabricated door head boards in a joint-staggering engaged mode to improve the connecting firmness of the prefabricated door frame vertical board bodies andthe prefabricated door head boards; prefabricated grouting grooves are formed in the outer side faces of the prefabricated door frame vertical board bodies, during door opening splicing, the prefabricated door head boards are inserted in the L-shaped notches of the two corresponding prefabricated door frame vertical board bodies to form a door opening, internal parting wall ribbon boards are spliced on the side face of the door opening, and prefabricated mortar storage grooves are compactly filled with mortar to form secondary connecting bodies with the internal bolting effect to be fixedly connected; and jointing grooves are formed in the edges of the outer sides of the L-shaped notches correspondingly and spliced with the adjacent prefabricated door head boards with jointing grooves andthe internal parting wall ribbon boards during door opening splicing to define anti-cracking edge sealing grooves, net laying and mortar smearing are conducted on the interiors of the anti-cracking edge sealing grooves to form anti-cracking connecting bodies, the connecting strength of joints is improved, and the phenomenon that as for an existing door opening structure, due to frequent opening and closing and vibration of a door, the spliced positions of the door opening are prone to being cracked is effectively avoided.

Description

technical field [0001] The invention belongs to the field of door opening structures of inner partition walls, and in particular relates to a prefabricated anti-cracking door frame vertical plate used for the door opening structure of inner partition walls with slats. Background technique [0002] When the interior partition wall slats are installed, the door opening is one of the important nodes. The existing interior partition wall slat installation door opening is to splice the door head panel at the corner position in the door opening. Due to the frequent opening and closing of the door, the upper part of the door opening Cracks are prone to occur at the horizontal and vertical joints at inner corners, so special construction treatment is required when installing and building door openings. According to market research, the following solutions are often used in current construction operations to solve the problem of door opening cracking. [0003] Option 1: Process the s...
