(1) Hall: the hall is a building with a slope on both sides of the roof, which has five ridges. Because the area is wider than the depth, the front and back slopes intersect to form a ridge, and the left and right slopes intersect with the front and back slopes to form four vertical ridges. The main frame and truss purlin of the hall are the same as the general beam frame, and there are two golden purlins on the left and right slopes and on the corresponding parts of the golden purlins on the front and back slopes to support the rafters of the two mountains. The two truss purlins intersect with the truss purlins of the corresponding steps on the front and back slopes at right angles under four vertical ridges. In the vertical plane of the central line of the golden truss purlins on the front and back slopes of the two hills, the downstream girders of each layer are arranged below and parallel to the purlins.
The girder is divided into upper, middle and lower floors, each of which is placed on the top of the truss purlin on the mountain, one end on the main girder frame, and on the top of the girder, the pier supporting the intersection of the diameter purlin on the mountain and the front and rear slope of the golden truss purlin is called the cross-golden pier, such as the melon pillar is called the cross-golden gourd pillar, and the intersection of the angles of the truss purlin on each floor is placed from the position of the cross-angle beam. The back end is cut with half mortise, and if the mountain is not pushed upward, it is intersected on the chiroprack, which is the skeleton of the four vertical ridges.
But in order to make the vertical ridge curve on the vertical projection, the method of pushing hill is usually adopted on the top of Ludian. The method of pushing hill is to reduce the size of each step from the golden pedestal to the ridge pedestal by 10% except that the eaves are square angles. If the seven purlin roof truss has three steps (eaves, golden steps, ridge steps) on each hill, each step is four feet one step, except that the first step (eaves) is a square angle without pushing the hill, the second step (golden steps) is pushing the hill by 1/10 of the eaves size (four feet); the second step is pushing the hill by 3 feet 6 inches; the third step is pushing the net size of the second step by 3 feet 6 inches. The net size of the third step (ridge pedestal) is 3 feet 2 inches 4 minutes, that is, the total size of the seven purlin pushing hill should be pushed outward is 1 feet 1 inch 6 minutes, and the total net size of the mountain through the pushing pedestal (that is, three pedestals and) is 10 feet 0 8 inches 4 minutes. For example, nine purlin and hill slope are four steps, and each step is four feet.
Which family is good in ancient architecture?
The first step is not pushing the mountain, the second step is pushing 4 feet 1/10 (4 inches) net 3-6 inches; the third township is pushing 1/10 according to 3-6 inches of the second step, 3-2-4 inches net; the fourth step is pushing 1/10 according to 3-2-4 inches of the third step, 2-9-1-6 inches net, that is, the spine step is pushing 2-9-1-6 inches. A per cent. That is to say, the total size of the nine purlins pushing the mountain outward is two feet two inches four centimeters, that is, after the position of the Taiping beam is pushed by the mountain pushing method, the golden ridge purlins are lengthened accordingly, so that the ridge purlins hang out of the ridge gourd pillars to hang on the thunder pillars, so the Taiping beam must be added. The length of the Taiping beam is that the two ridges of the front and back slopes are placed on the gold truss purlin on the front and back slopes, and then a thunderbolt is added to the Taiping beam to support the purlin.
(2) Hard hill: Hard hill has only two slopes, the left and right ends are brick gables, Gables have front and rear eaves, the gold pillar is in the mountain column, the top of the ridge purlin, in the crack with the same level of high position, there are inserted coffins from the eaves pillar straight into the mountain column, forming a girder frame, known as a row of mountain coffin, row of hill each girder frame has a single-step beam. The construction method of the double step beam and even the three step beam is the same as that of the single step beam and the double step beam.
